How is the effervescent tube moisture-proof

 The effervescent tube is a special packaging used to store large-dose medicines such as effervescent tablets and candy tablets. Most of the medicines in this type of tablets contain auxiliary materials such as starch, which are prone to fragments, deliquescent and adhesion after being damp. As a special packaging for these drugs, how can the effervescent tube be moisture-proof?

84mm effervescent tablet tube

The moisture inside the drug packaging mainly comes from two aspects. One is the certain water molecules contained in the tablet itself during the compression process. The other is that in the packaging process, the raw materials will also contain a small amount of water molecules. Generally, in order to maintain the dryness inside the package, a desiccant is placed in the medicine bottle. These desiccants will absorb the moisture inside the package and maintain the stability of the medicine.

But the effervescent tube is different from ordinary medicine packaging. Due to the larger dosage form of the tablets and the stacked storage method between the tablets, there is no extra space inside the packaging for the desiccant. After a special design, a small drug warehouse is designed on the cap of the effervescent tube to store silica gel and molecular sieve, which is what we usually call a moisture-proof cap. Such a design can not only absorb internal water vapor and maintain the stability of the drug, but also prevent direct contact between the desiccant and the drug, which is more conducive to the safety of the drug, and to a certain extent, it also avoids the risk of children ingesting the desiccant by mistake.

The effervescent tube guarantees the stability of the medicine with its unique moisture-proof cover. At present, the design of the moisture-proof cover has also been applied to more medicine packaging and played a more important role.

The characteristics of two kinds of protective caps of cow syringe

Mastitis is a common and frequently-occurring disease in dairy cows, especially during the dry period. Using a cow syringe for udder perfusion treatment is an effective treatment method. Its protective caps are divided into breakable and non-breakable. What are the characteristics of these two types?

5ml syringe for cow mastitis

Dairy cow mastitis is mostly recessive, the initial symptoms are not obvious, and it is difficult to find during production, so it is easy to delay the optimal treatment period, which leads to the lack of high-stage lactation performance in milk cows within 2-3 months after delivery. Full performance, severely cause the lactating cows to lose milking ability and be eliminated. Production statistics show that mastitis during the dry period will cause more than 25% of the lactation loss in the next lactation period.
The cow syringe is composed of a pipe sleeve, a push rod, a piston, a protective cap and other structures, and the protective cap has two forms: breakable and non-breakable. The breakable protective cap enters the cow's udder shallowly, can maintain the integrity of the nipple tube, and minimize the entry of bacteria into the gland. The non-breakable protective cap goes deeper into the breast, stretches the sphincter muscles, expands the nipple duct, and is easier to introduce bacteria.

The above is the difference between the breakable cap and the non-breakable cap of the cow udder perfusion device. In general, to reduce the bacterial contamination of the cow udder, the operator should perform strict disinfection before the udder injector to reduce the probability of infection from the root cause. 

Common problems in blowing process of tablet bottles

 There are many types of medicines. Among them, tablets are the most common type, divided into ordinary tablets, dispersible tablets, sustained-release tablets, etc. These drugs are stored in special tablet bottles. The quality of the pharmaceutical packaging is related to the stability of the medicine. The tablet bottle will also encounter some quality problems during the blow molding process. The following are the common ones:

child proof bottle

1. Part of the tablet bottle is excessively stretched. This is due to the central temperature attitude or pre-blowing formed too early, and it hits the stretch rod.

2. There are wrinkles in the bottom of the bottle. The temperature at the bottom is too high, the pre-blowing is too late and the pre-blowing pressure is too low, it may appear this kind of situation, and the flow is too small.

3. The overall thickness of the plastic bottle is thinner. This phenomenon speeds up the pre-blowing time, improves the pre-blowing pressure, and increases the air flow of the plastic bottle.

4. The bottom of the plastic bottle is whitish. The preform of the plastic bottle is too cold, stops stretching if it is too hot, pre-blowing is too early or the pre-blowing pressure is too high.

5. There is a magnifying glass at the bottom of the bottle, and there is too much material at the bottom of the bottle. The pre-blowing is too late, the pre-blowing pressure is too low, etc.

6. The entire plastic bottle does not look so transparent, but rather turbid. This is due to the insufficient cooling time of the tablet bottle.

7. The eccentricity of the bottom of the bottle is related to the temperature of the plastic preform, stretching, pre-blowing, and high-pressure blowing. Reduce the temperature of the plastic preform, accelerate the stretching speed of the plastic bottle, check the gap between the tie rod head and the bottom mold, extend the pre-blowing time, and reduce the pre-blowing pressure. Or postpone high-pressure blowing to check whether the preform is eccentric.

8. The tablet bottle is also particularly prone to deformation. This is because the wall thickness difference between the longitudinal wall thickness position and the radial wall thickness position is too large. The shrinkage formed by the position of the parting line of blow-molded container products is more serious than that of the adjacent position, which is that the cooling rate of the thicker area is much slower than that of the surrounding area. Different cooling speeds result in different shrinkage and deformation. This kind of defect is best dealt with by controlling the longitudinal wall thickness and the radial wall thickness at the same time.

There are many problems in the blow molding of tablet bottles, and some defects are minimal, but even small errors can cause quality problems in the finished bottle. Only by controlling these details can high-quality bottles be produced.

What medicines can be contained in the tablet medicine bottle

 Tablet medicine bottles are generally made of polymer materials such as polyethylene, polypropylene or polyester. This type of packaging bottle has a large mouth and a desiccant is placed inside the bottle to absorb moisture. It can not only be used as a packaging for tablet medicines, It can also contain capsules and pills.

50ml desiccant bottle

Capsules: The drugs packed in capsules are generally powders or granules that are irritating to the esophagus and gastric mucosa, or have a bad taste, are easy to volatilize, are easily broken down by saliva in the mouth, and are easily inhaled into the trachea. These medicines are packed in capsules, which not only protects the properties of the medicines from being destroyed, but also protects the digestive organs and respiratory tract.

Pills: Pills are spherical or spheroid-like preparations made of medicinal powders or medicinal material extracts plus suitable binding auxiliary materials. Classification according to the preparation method: 

①Plastic pills, such as honey pills, paste pills, concentrated pills, wax pills, etc.; 

②Pan pills, such as water pills, water honey pills, concentrated pills, paste pills, etc.; 

③Drip pills (dropping pills). Classified by excipients: water pill, honey pill, water pill, paste pill, wax pill, etc.

HDPE pill bottle

Whether it is tablets, capsules, or pills, these drugs are all solid preparations, which have high requirements on the tightness and moisture resistance of the packaging. The tablets and medicine bottles have abundant raw materials, various shapes and colors, and polymer materials can also be used. By adding additives to improve its performance, it can meet the storage requirements of capsules and pills.

Pet nutrition cream in the form of syringe has become a trend

 Pet nutrition cream is a standing item for families with pets. It is mainly suitable for cats and dogs in frail elderly, post-operative postpartum, lactation and after strenuous exercise. With the increase in the number of pet owners, people have higher requirements for the packaging of pet nutrition cream, and the packaging in the form of a syringe is favored by pet owners and has become a trend.

15 ml syringe for pets feeding

At present, there are two main types of pet nutrition paste packaging on the market. One is the aluminum-plastic tube packaging similar to toothpaste. This type of packaging needs to squeeze the tube body when feeding pets. If the extruded paste is not consumed, it will easily retract again. Inside the tube, it causes secondary pollution to unused drugs. In addition, the tubular packaging is also easy to be bitten by pets, causing excessive consumption, which is not conducive to the health of pets.
Another packaging of pet nutrition cream is in the form of a syringe. This packaging is made of polymer materials and includes five parts: tube sleeve, push rod, piston, protective cap, and positioning ring. It can not only store medicines, but also provide feeding Function. By opening the protective cap, the push rod can be directly fed to the pet, and it is not easy to be bitten. For companies with special requirements, such packaging can also be used with a scale printed on the push rod and used with a positioning ring to make the amount of nutritional cream more accurate.
Compared with the two types of packaging, the syringe package is more convenient to use, can reduce pollution, and can control the dosage of the nutritional cream. Pet owners are more inclined to choose the nutritional cream in the form of the syringe package.

The quality control points of eye drop bottles

 With the prevalence of electronic products, the incidence of various ophthalmic diseases such as glaucoma, cataracts, and dry eye disease remains high. Eye drops are commonly used drugs in ophthalmology. The product quality of eye drop bottles will directly affect the safety and safety of the drugs. Stability, therefore, controlling the quality of packaging is of great significance to the safety of patients' medication.

5ml eye dropper bottle]

Manufacturers of eye drops should select appropriate eye drop bottles in accordance with the barrier properties of packaging materials and the packaging form of the drug, taking into account other factors such as transparency, aesthetics, ease of use, and economics. Quality control mainly considers the following aspects:

1. The eye drops themselves should have a certain degree of stability during storage and use.

2. The packaging materials of medicines must not contain substances that may affect the medicines during use.

3. Due to the difference in eye drop bottle packaging materials, container formulations, selected raw and auxiliary materials, and production processes, some components may be dissolved out by the drugs in contact, or interact with drugs, or be immersed and corroded by drugs for a long time Directly affect the quality of medicines.

4. If the plastic bottle is made with improper dosage, the migration of its trace components will change the medicinal effect of the medicine, and even endanger the health of the person taking the medicine.

5. The pharmaceutical packaging material and the packaged drugs must not react in a chemical or biological sense.

Analysis of the causes of burrs in the effervescent tube

 The effervescent tube is a special packaging for candy tablets such as effervescent tablets. It is composed of a bottle cap and a bottle barrel. Generally, injection molding technology is used in the processing method. However, burrs will appear during the production process. What is the cause?

plastic effervescent tube 92mm*21mm

There are many reasons for the burrs of the effervescent tube, which can be analyzed from the following aspects:

1. The clamping force is too low

Compared with the projected area of the molded part, if the clamping force is small, there will be a gap between the movable mold and the static mold due to the injection pressure, which inevitably produces burrs. Especially when the side gate is placed on the hole close to the center of the p art, since the molding gate requires a large injection pressure, it is very easy to produce burrs.

2. Deformation of the injection mold

If the originality of the mold is insufficient, it will deviate due to the injection pressure. If there is a hole near the center, burrs will be generated around the hole. When using the center hole to open the side door, the hole and the perimeter of the runner will also be created. glitch. The burrs generated for this reason are caused by poor mold manufacturing and are therefore difficult to repair. Reinforcing the mold can reduce burrs.

3. Plastic fluidity is too good

Just because the fluidity of the plastic is too good, theoretically speaking, it is not the cause of the burr. However, when the fluidity of the plastic is too good, even a small gap may be penetrated by the plastic, so burrs are prone to appear. In order to eliminate such burrs, the melting temperature or injection pressure can be reduced, and the mold temperature or injection speed can also be reduced.

4. There are foreign bodies on the surface of the injection mold

Foreign matter on the clamping surface of the mold will inevitably produce burrs. In order to solve this problem, it is obvious that the surface of the mold must be cleaned to close the clamping surface.

Burrs in the effervescent tube can be analyzed from the above aspects to find out the specific reasons to ensure the quality of the finished product.

How to put cockroach-killing glue bait through plastic syringe

 Cockroaches are one of the four major pests, which have the characteristics of rapid reproduction, which seriously affect people's lives. Cockroach-killing glue bait is a new type of poisonous bait medicine. Using the advantages of plastic veterinary syringe packaging, it can achieve the purpose of eradicating cockroaches. Then how to use this kind of glue bait?

Generally, it can reach the characteristic of infecting the whole litter after eating, and achieve the purpose of completely eradicating cockroaches. It is used in many cockroach medicines. A convenient and effective medicine.

paste syringe

The packaging of the anti-cockroach bait is a plastic syringe, which is composed of a tube sleeve, a push rod, a piston, and a protective cap, which has the advantages of convenient use and reduced pollution. When in use, open the protective cap, push the push rod, and directly put the glue bait on the stove, cabinet, drawer and other places where cockroaches frequent. When distributing the medicine, follow the principle of "smaller amount and more", and one point every 15-20 cm Point, the place where cockroach damage is serious can increase the distribution point. After dispensing the medicine, if the medicine is not used up, the protective cap of the veterinary syringe needs to be re-capped to ensure the tightness of the package.
The needle of the plastic syringe is relatively thin and can reach the gaps, corners and other places that are not easy to wipe off. As long as there is a glue bait, it will generally be effective within two years. It should be noted that the application time should be as far as possible between 8:00-9:00 in the evening. This time is the peak period for cockroaches to come out for food, which has a better effect of killing cockroaches.

Innovation in production and design of tablet bottles

 With the rapid development of the pharmaceutical industry, the demand for pharmaceutical packaging is constantly innovating, such as adding new packaging materials and adopting more advanced production processes. Among many packages, the innovation in production and design of tablet bottles is particularly obvious.

child proof bottle

Although my country's pharmaceutical packaging industry started relatively late, it has become an important part of the development of the pharmaceutical industry after recent years of development. Tablet bottles are plastic bottles used to contain tablets and drugs. Its initial production materials are mainly polyethylene, polypropylene, and polyester. The processing techniques include injection blowing, extrusion blowing, injection stretch blowing, etc., with the development of technology With continuous updates, more polymer materials have been developed, such as high barriers, and the production process has been further improved. For example, the one-step injection stretch-blowing process has gradually replaced the two-step process, and the product quality is more stable.

50ml desiccant bottle

In terms of design, the tablet bottle is more user-friendly. In our daily lives, incidents of children accidentally ingesting medicines by opening the package occur from time to time. A package with a function of preventing children from opening can avoid this situation well. The medicinal moisture-proof bottle containing a desiccant in the bottle cap is an innovation in the design of the tablet bottle for the anti-dampness of the medicine.

Of course, there are still many new-style pharmaceutical packaging appearing, and their appearance has enriched the packaging market and made it convenient for consumers. On the other hand, for tablet bottle manufacturers, it has also promoted healthy competition among enterprises based on technology and innovation.

Selection of veterinary drug packaging and many hidden dangers of drug deterioration

 Veterinary drugs play an important role in the prevention, treatment, and diagnosis of animal diseases. Common types of veterinary drugs include serum products, vaccines, diagnostic products, proprietary Chinese medicines, antibiotics, disinfectants, etc. Different drugs have different requirements for veterinary drug packaging. Improper selection can easily lead to deterioration of medicines and even endanger animal health.

vaccine bottle

Under normal circumstances, if the following phenomena occur in a veterinary drug, it means that the drug has deteriorated. Not only can it not have the expected efficacy, but it may also increase its toxicity. For example, the shape and color of the drug contents are inconsistent with the label instructions; the powder absorbs moisture and ferments and becomes smelly; the oral liquid appears flocculent and sediment; the injection solution changes color, turbidity, precipitation or crystal precipitation, etc., all indicate that the drug has deteriorated and cannot be used. If an animal is taken or injected with deteriorating drugs, it will seriously affect the animal's health and cause certain economic losses to the farm.

paste syringe

On the one hand, the cause of drug deterioration is related to the performance and storage period of the drug itself, and on the other hand, it has a lot to do with the quality of the veterinary drug packaging. Packaging not only protects the safety of the drug, but also has sealing properties, which can prevent foreign impurities from invading the inside of the package and affecting the drug. Therefore, when choosing veterinary drug packaging, pharmaceutical companies should strictly examine the quality of the product to ensure the safety and safety of the drug within the validity period. Stability, to avoid the deterioration of the drug and cause serious consequences.

With the increasing trend of population aging and the increasing single population, the number of pet owners continues to grow. As a rigidly-needed item, the market demand for pet nutrition cream has also increased, and the syringe factory will also welcome opportunities while the industry is developing rapidly.

syringe for pet feeding

Pet nutrition cream is a kind of quick tonic nutrition that is easy to digest and absorb and is very practical. It is mainly suitable for developmental stage, old age, disease recovery period, malnutrition, pregnancy and lactation, low immunity, chronic disease, weaning period. For pets with picky eaters and partial eclipses, in order to enhance their pet’s resistance, pet owners generally stock nutrient creams at home.
At present, there are two packaging forms for pet nutrition paste packaging in the market: toothpaste type and syringe. Relatively speaking, toothpaste type packaging is easy to be bitten by pets, resulting in excessive consumption of nutrient paste, which is not conducive to the healthy growth of pets. In addition, this kind of packaging is easy to shrink and cause secondary pollution. The syringe is a new type of packaging that has both storage and feeding functions. The syringe design is not easy to bite. When feeding, open the protective cap and push the push rod, which is convenient to use and reduces pollution. It can also print scales on the push rod according to the needs of pharmaceutical companies, and use it with the positioning ring to make the dosage of the nutritional cream more accurate.

The role of intramammary tube in treatment of dairy cow endometritis

 Endometritis is a common and frequently-occurring disease in dairy cows. It can cause long-term emptying of cows, implantation of fertilized eggs and early embryonic death. It is often chronic in clinical practice and difficult to detect. If it is not detected and treated in time, it will give The aquaculture industry caused huge losses. Among many treatment methods, using a intramammary tube for drug infusion therapy to the uterus is a fast and effective method.

intramammary syringe

The cause of dairy cow endometritis is mainly caused by pathogenic microorganism infection or improper feeding and management. Common treatment methods include uterine washing, uterine perfusion, traditional Chinese medicine therapy, hormone therapy and systemic therapy.
(1) Flush the uterus. Flushing the uterus is an effective way to treat acute and chronic endometritis. The principle of treatment is to clean the uterus, eliminate inflammation, and purify the uterus through the use of antibiotics. Once a day or every other day, rinse repeatedly each time until the reflux fluid becomes clear.
(2) Uterine perfusion. Use the intramammary tube to infuse the drug into the uterus. When in use, the protective cap is opened, the drug delivery end is connected to the catheter, and the drug is inserted into the cow's uterus for drug delivery. This treatment method is simple to operate, less irritating to the cow, reduces drug pollution, and is safer and more effective.
(3) Traditional Chinese Medicine Therapy. For those who do not have uterine sluggishness with lochia, administer Yimu Shenghuasan. The prescription is: motherwort 50g, angelica 120g, chuanxiong and peach kernel 45g, dried ginger (pao), moxibustion each 10g, reconstituted with boiling water, and irrigated with temperature, once a day for 5 days. The number of doses can be increased or decreased according to the condition.
(4) Hormonal therapy. On the 16th to 17th days of the estrus cycle, 20 mg of ethestrol was injected into the affected cows. The purpose is to increase the proliferation of uterine epithelial cells, hyperemia of the mucosa, and strengthen the peristalsis of the uterine muscles, which is conducive to the full manifestation of estrus behavior and the full elimination of uterine inflammation. Then, wash and perfusion with penicillin were performed once.
(5) Systemic treatment. According to the general condition, fluid, sugar, salt and alkali can be supplemented.
The above are several common treatment methods for cow endometritis. The specific treatment method to choose depends on the condition of the cow and the breeding environment. It is important to note that before using the intramammary tube for uterine perfusion treatment, it is necessary to make sure that the intramammary tube is packaged intact and there is no leakage to ensure the safety of medication and the therapeutic effect.

What is the function of the cap of the veterinary injection vial

 The cap is an important part of the bottle, which not only plays the role of sealing the mouth of the bottle, but also improves the aesthetics of the entire bottle. There are many types of bottle caps, and different bottles have different needs. The bottle caps of veterinary injection vials mainly use rubber stopper aluminum caps.

plastic injection vial

Veterinary vaccines are generally injection preparations, and the rubber plug aluminum cap is more convenient for practical application. This kind of cap is composed of an aluminum cap and a butyl rubber stopper. The rubber stopper has good air tightness, heat resistance, aging resistance, acid and alkali resistance, and high cleanliness, which can block the drug in the bottle and the aluminum cap directly. Contact, avoid the reaction between the two and affect the effect of the drug. Its unique chemical stability and excellent sealing properties ensure the quality of medicines and improve the safety of medicines.
The aluminum cover is a very strong material that will not rust or break easily. It is destructive after opening and can effectively prevent theft. In addition, it also has the advantages of cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and it is non-toxic, non-absorbent, non-dust, peeling, and increased, and the sealing performance is very good. Various brand patterns, anti-counterfeiting signs, etc. can be designed on the top of the lid, which brings certain brand value-added to the development of the enterprise.
As an inseparable part of the veterinary injection vial, the rubber stopper aluminum cap not only guarantees the tightness of the package, but also has high aesthetics. The small bottle cap can play a finishing touch.

How to use veterinary syringes for different purposes

 The veterinary syringe is a product of constantly changing market demand and continuous update and iteration of packaging products. It is mainly used for the packaging of drugs such as dairy cow mastitis, dairy cow endometritis, pet nutrition ointment, and cockroach medicine. Depending on the application, the use of veterinary paste syringes is also different.

paste syringe

The plastic veterinary syringe is composed of a sleeve, a push rod, a piston, a protective cap or a positioning ring, and can not only be used as a container for medicine storage, but also can directly realize the function of drug delivery. According to different uses, veterinary syringes are divided into two methods: direct administration and catheter administration.

cockroach syringe

Direct drug delivery: This drug delivery method means that the user can directly administer the drug without using other accessories after opening the protective cap. Medicines such as pet nutrition cream, cockroach medicine, horse oral paste, and camel nutrition cream can be directly administered.
Drug delivery via catheter: drugs such as dairy cow mastitis and dairy cow endometritis generally need to be administered via a plastic catheter. The catheter is connected to the needle of the plastic syringe, and the drug can be directly introduced into the diseased milk area or to the dairy cow. The uterus is perfused and flushed to achieve the therapeutic effect.
Although there are differences in the way of administration, it has to be said that this packaging design facilitates the administration of many drugs. For example, through this packaging, the cockroach-killing bait can reach a deeper gap, making it difficult for pets, children, etc. to reach it. Achieve a good effect of killing cockroaches.

Plastic syringe is a packaging form of cockroach medicine

Cockroaches are one of the main urban pests, which bring many troubles to our lives. In order to solve the cockroach problem, cockroach medicine appeared. The packaging of cockroach medicine varies according to the dosage form of the medicine. There are three common types: bag, spray, and veterinary syringe. Among them, the plastic veterinary syringe is favored by the market due to its convenient use.

There are many types of cockroach medicine, mainly divided into four types: chemical, physical, biological, and natural. In the common packaging, bagged and sprayed are two types that appeared earlier. The pharmaceutical dosage form of bagged is generally powder or granule, and the sprayed package is liquid, but the places where cockroaches are infested are mostly near water sources and near food. There are many inconveniences when applying pesticides in places near heat sources, various gaps, and wooden furniture, especially in various gaps. In order to facilitate the application of pesticides, a new type of plastic syringe packaging has appeared and has become an important packaging form of cockroach medicine.

The plastic veterinary syringe is composed of a tube sleeve, a push rod, a piston, a positioning ring, and a protective cap. It is a new type of packaging with both drug storage and drug delivery functions. Open the protective cap when administering the drug, and put the drug directly into the place where cockroaches frequent. This kind of packaged needle tube has a relatively thin lead-out head, and it is convenient to administer even a very small gap. The built-in medicine is usually a paste-like gel bait, which can maintain the efficacy for a long time after application.

Ease of use is the basic requirement for the packaging of medicines, and it is also an important factor in improving customer experience. At present, the perfusion device has gradually replaced the traditional packaging and has become an important packaging form of cockroach medicine. 

Production process of plastic paste syringes

There are various production processes for veterinary drug packaging, such as injection molding, extrusion blowing, and injection stretch blowing. The veterinary syringe consists of a sleeve, a push rod, a piston, a protective cap, and a positioning ring. So what is its production process?

paste syringe

The veterinary paste syringe is produced by injection molding process, one-time molding, no waste, accurate product size, uniform weight. The production process is as follows:
1. The filling stage
Filling is the first step in the entire injection cycle process. The time starts from when the mold is closed and the injection is started until the mold cavity is filled to about 95%. In theory, the shorter the filling time, the higher the molding efficiency, but in practice, the molding time or injection speed is restricted by many conditions.
2. Pressure holding stage
The function of the holding pressure stage is to continuously apply pressure, compact the melt, and increase the density of the plastic to compensate for the shrinkage behavior of the plastic. During the pressure holding process, the back pressure is relatively high because the mold cavity has been filled with plastic. In the later stage of pressure holding, the material density continues to increase, and the plastic is gradually formed. The pressure holding stage should continue until the gate is solidified and sealed. At this time, the cavity pressure in the pressure holding stage reaches the highest value.
3. Cooling stage
In the injection molding mold, the design of the cooling system is very important. This is because the molded plastic product can only be cooled and solidified to a certain rigidity, and then the plastic product can be prevented from being deformed due to external force after being demolded. Since the cooling time accounts for about 70-80% of the entire molding cycle, a well-designed cooling system can greatly shorten the molding time, improve injection molding productivity, and reduce costs.
4. Demoulding stage
Demoulding is the last link in an injection molding cycle. There are two main ways of demolding: ejector rod demoulding and stripping board demolding. When designing the mold, it is necessary to select an appropriate demolding method according to the structural characteristics of the prefilled syringe to ensure the quality of the product.
The above is the production process of veterinary paste syringes. Any link of filling, holding pressure, cooling and demoulding cannot be ignored. Only by controlling the various production processes can high-quality products be produced.

What is the function of the cap of the veterinary injection vial

The cap is an important part of the bottle, which not only plays the role of sealing the mouth of the bottle, but also improves the aesthetics of the entire bottle. There are many types of bottle caps, and different bottles have different needs. The bottle caps of veterinary injection vials mainly use rubber stopper aluminum caps.

plastic injection vial

Veterinary vaccines are generally injection preparations, and the rubber plug aluminum cap is more convenient for practical application. This kind of cap is composed of an aluminum cap and a butyl rubber stopper. The rubber stopper has good air tightness, heat resistance, aging resistance, acid and alkali resistance, and high cleanliness, which can block the drug in the bottle and the aluminum cap directly. Contact, avoid the reaction between the two and affect the effect of the drug. Its unique chemical stability and excellent sealing properties ensure the quality of medicines and improve the safety of medicines.
The aluminum cover is a very strong material that will not rust or break easily. It is destructive after opening and can effectively prevent theft. In addition, it also has the advantages of cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and it is non-toxic, non-absorbent, non-dust, peeling, and increased, and the sealing performance is very good. Various brand patterns, anti-counterfeiting signs, etc. can be designed on the top of the lid, which brings certain brand value-added to the development of the enterprise.
As an inseparable part of the veterinary injection vial, the rubber stopper aluminum cap not only guarantees the tightness of the package, but also has high aesthetics. The small bottle cap can play a finishing touch.

What is the function of the positioning ring on paste syringe

The paste syringe is a special kind of medicine packaging, mainly used for the packaging of dairy cow mastitis medicine, pet nutrition ointment, cockroach medicine and other medicines. Sometimes we will develop a small circular ring on the push rod. This part What is its function?

The design of the paste syringe comes from the original syringe, and adds the function of storing medicine on the basis of injection. Its composition mainly includes a sleeve, a push rod, a piston, a protective cap, and a positioning ring. The ring on the push rod is the positioning ring, and its main function is to determine the dose of medicine. For example, pet nutrition ointment and dairy cow endometritis drugs require relatively high doses of drugs. If the drugs are excessive or too small, it is not conducive to the health of the animals. The design of the positioning ring can make the dose of the drug more accurate.
Generally, packages equipped with a positioning ring will print a scale on the push rod at the same time.  After the drug dosage is determined according to the medication instructions, the positioning ring is fixed at the standard scale. The push rod will stop and continue to advance when it reaches the position of the positioning ring. Achieve precise drug delivery. Of course, not all prefilled syringes are equipped with a positioning ring. For example, when used for cockroach medicine, the medicine is applied in a spot, and there is no special requirement for the accuracy of the medicine.
The positioning ring makes the dosage of the paste syringe more accurate, thus realizing the scientific feeding of pets. Its functionality is being used by more and more medicines, such as camel nutrition ointment and horse oral paste.
