Common problems solutions in twin neck measuring bottle molding

 The twin neck measuring bottle is an innovative type of packaging, which is widely used in solutions that need to be diluted, such as pesticides, pH buffers, and fluorescent leak detectors. This kind of special-shaped bottle is processed by extrusion and blowing technology, and some failures may be encountered during the forming process, but as long as the specific reason is found, the corresponding solution can be selected to ensure the quality of the bottle.

Common problems in the molding process of twin neck measuring bottle include the following:
1. Reasons for the rough surface of the parison: ①The melt temperature is too low and the plasticization is not good; ②Extrusion and pressing speed are too fast; ③Improper die structure.
    Solution: ①Adjust the molding temperature (mainly the die); ②Appropriately reduce the speed; ③Increase the shaping section.
2. Reasons for product deformation: ①The melt temperature is high and the blow molding cycle is short; ②The cooling efficiency of the mold body is poor; ③The blow molding pressure is small.
    Solution: ①Reduce the melt temperature and extend the blow molding time; ②Increase the cooling water volume and cooling temperature, and check whether the cooling water channel is unblocked; ③Increase the blow molding pressure to not less than 0.196MPa (2kg/cm2).

3. Reasons for bubbles in the product: ①The raw material has high moisture content or volatile matter; ②The molding temperature is too high, and the part is overheated and decomposed.
    Solution: ①Pre-dry the material or change the formula; ②Reduce the molding temperature to prevent local overheating or partial storage of the material.
4. The obvious reasons for the suture line of the product: ①The temperature of the die is too low; ②The resin melt viscosity is large or the MFR is small; ③The structure of the die is not good.
    Solution: ① adjust the temperature of the die; ② increase the molding temperature or replace the material with a large MFR; ③ increase the choke device or lengthen the shaping section.
5. Reasons for dents in the cutting edge: ①Improper overflow angle of the cutting edge; ②The closing speed of the mold is too fast.
Solution: ① Repair the angle of the knife edge; ② Slow down the mold closing speed.
In the production process, all aspects such as raw materials, temperature, blow molding time, etc. must be strictly controlled, so as to produce high quality twin neck measuring bottle.

Requirements for packaging of veterinary drugs for different drugs

 Veterinary drugs refer to substances used to prevent, treat and diagnose animal diseases or to purposely regulate animal physiological functions, including vaccines, diagnostic products, antibiotics, biochemical drugs, Chinese medicinal materials, disinfectants, etc., according to the different drug formulations, the packaging of veterinary drugs The requirements are also different.

Although there are many types of veterinary drugs, they are mainly divided into two categories: liquid drugs and powder drugs according to their dosage forms. Liquid medicines generally choose plastic packaging bottles, and the raw materials mainly include polyethylene, polypropylene, polyester, high barrier, etc. Oral liquid and injection medicines will require the bottle to be transparent and shading. In order to ensure that the medicine is not decomposed and deteriorated under the influence of light, a brown polyester bottle is chosen. Liquid medicines have high requirements on the tightness of the bottle, so in the choice of bottle caps, choose more aluminum caps with rubber plugs to achieve a good sealing effect.

The powder dosage form accounts for a relatively small proportion of veterinary drugs. This type of drug requires moisture-proof packaging for veterinary drugs. Plastic packaging bottles are usually the main ones, sealed with aluminum foil gaskets, and a desiccant is placed in the bottle to ensure the dryness of the internal environment. , Prevent the medicine from being damp and deteriorate
In addition, some highly corrosive drugs (such as disinfectants) require high barrier properties for veterinary drug packaging, and packaging of high barrier materials will be selected to ensure that the drug is in a good state of preservation.
The above are the requirements for the packaging of veterinary drugs for several different veterinary drug types. Choosing the appropriate veterinary drug packaging according to the characteristics of the drug is the basic condition to ensure the safety and effectiveness of the drug.

Application of double-neck bottle in disinfectant packaging

 Disinfectant is almost a necessary cleaning product for every family, and it is widely used in agriculture, medical treatment, animal husbandry and other fields. Disinfectants need to be diluted before they can be used. The veterinary packaging is mostly plastic bottles. In order to facilitate the control of the dilution ratio in use, a two neck bottle with a quantitative function has gradually become the first choice for disinfectant packaging.

Most disinfectants are corrosive at high concentrations and can damage the environment, objects, and animal mucous membranes. Especially for animal mucosa, the volatilization of high-concentration disinfectants will cause mucosal damage, resulting in mucosal congestion, bleeding, and local ulceration. Therefore, the dilution concentration of the disinfectant is related to the disinfection effect. The higher the concentration, the better, the appropriate dilution ratio can minimize the adverse effects on the human body and the environment.

In view of the importance of the dilution ratio of the disinfectant, it is generally necessary to control the specific concentration with the help of a measuring cup. In order to be convenient to use, packaging manufacturers have developed a two-neck bottle packaging that combines storage and quantitative functions in combination with the actual needs of the market. This kind of packaging adopts two bottle mouth designs, namely the bottle mouth of the quantitative bottle with marking and the bottle mouth for storing disinfectant. When using, open the cap of the quantitative bottle and gently squeeze the bottle body to make the appropriate amount of disinfectant enter the quantitative bottle. Pour the amount of disinfectant into the dilution container according to the usage amount. This method of use reduces the intermediate steps of pouring the disinfectant into the measuring cup, and can reduce waste while being convenient to use.

At present, two-neck bottles have been widely used in the packaging of animal nutrition solutions, disinfectants, herbicides, pesticides, etc., and consumers are more willing to choose such convenient packaging when purchasing drugs.

Application of twin-neck bottle in veterinary insect repellent drugs

 Parasitic diseases are common diseases in the livestock breeding industry, and regular deworming of livestock is also an important task in the daily management of farms. At present, the anthelmintic drugs on the market are mainly powder and liquid preparations. For the convenience of use, an anthelmintic drug package with a two-neck bottle design has been universally recognized by the market.

Veterinary anthelmintics are mainly used for the prevention and treatment of nematode diseases, mites and parasitic insect diseases in sheep and pigs. From the perspective of the route of administration, veterinary anthelmintics are mostly used by injection, oral administration, painting, etc., depending on the dosage form. , The method of administration is also different. The emergence of two-neck bottle packaging has made the route of administration more diversified, and has also given farmers more choices.

There is a water barrier inside the bottle body of the two-neck bottle. The water barrier divides the bottle body into an upper water tank and a lower water tank. The upper water tank is marked with a scale and can be used as a quantitative bottle. The lower water tank is a space for storing medicines. When in use, open the cap of the measuring bottle and gently squeeze the bottle body to make the appropriate amount of medicine enter the quantitative bottle. The mouth of the measuring bottle is on the top and the mouth of the medicine bottle is on the bottom. The back midline is poured onto the back of the livestock. The liquid medicine can penetrate into the body through the back of the livestock to achieve the effect of deworming. This kind of packaging combines quantitative and storage functions into one, making the way of administration more convenient.

The innovation of science and technology has caused continuous changes in all walks of life, and the emergence of two-neck bottles is the product of this change. Veterinary drug companies should not only focus on product quality in the choice of veterinary packaging, but also need to think more about the convenience of customers.
