Process design of pet oral syringe

Pet nutrition cream packaging is divided into many materials, common ones are similar to toothpaste hoses, or aluminum-plastic tubes, and there are also syringe-like packaging. However, as a container for pet medicine, whether in terms of material or structure, performance The requirements are very strict.

Because the pet medicaments contained are different, the requirements for pet nutrition cream packaging are also different, so special attention should be paid to the design and production of pet drug packaging. The choice of raw materials for pet drug packaging should pay attention to the nature of the material and the packaged drug, and whether there will be a reaction between the two. They will permeate, dissolve, and adsorb each other, which will affect the dissolution, adsorption, and influence of the drug. The composition has changed, so when a new pet medicine is selected for packaging, a loading test should be performed to examine the compatibility between the materials used and the medicines in order to confirm whether the packaging for the medicine is suitable.

Pet drug syringe should protect the drug from light and heat sources, as well as moisture absorption, oxidation, and dissipation requirements. With the lid locked, the materials used for packaging have excellent barrier properties against water vapor and oxygen. In terms of design of the packaging bottle body, in order to ensure the fit and sealing effect of the bottle mouth and the cap, the bottle mouth and the thread part are designed to be thicker, and the thickness of the bottle body part should be thinner. Moreover, the bottle body should have a thickening trend, and strive to achieve a uniform thickness in all parts. In order to meet the requirements of high-speed automated canning lines, the bottle body should have good stability, and the height-diameter ratio should generally not be too large, and should not exceed three. The proportion of the bottle should not be too small. In addition to considering the size of the drug and ease of use, the requirements of the filling machine should also be considered.

The veterinary syringe size error should be controlled within the specified range to ensure the smooth filling of the medicine.

In addition to using advanced equipment to produce pet pharmaceutical packaging, it must also comply with the corresponding production technology and management. In addition, research on product design and new materials should be strengthened in order to meet the requirements of pet pharmaceutical packaging.

Effervescent tube packaging

The effervescent tablet packaging is mostly plastic hollow packaging with a certain moisture-proof function, which is mainly composed of two parts, a moisture-proof cap and a tube; the bottle cap adopts an integrated design, and the built-in desiccant in the bottle cap can effectively absorb the water molecules in the package.

There is a bottle buckle, the anti-theft ring will be stuck when the moisture-proof cover is covered, and it will be replaced automatically when it is opened. The connection has been tested for 300 breakpoints, worry-free filling, easy to open; 

2, stopper spring: optional 

3, imported desiccant, the final product rate ≤ 2%, higher than the national standard 2.8; desiccant saturated moisture absorption rate at Between 24% and 26%, to ensure that the drug is kept in good condition; 

4, Germany imported equipment to produce advanced molds, constant environment production, to ensure product quality is stable; 

5, automatic desiccant filling equipment, accurate dosage, more conducive to Control the batch; the stability of the quantity of products; 

6, provide printing or pre-sticking stickers service, improve the overall effect of the product and enhance the brand value.

gel filling way of veterinary syringe

The plastic veterinary syringe is usually composed of a sleeve, a push rod, a piston, a positioning ring and a protective cap. This product can be used as a drug packaging and a syringe, which not only saves the cost of pharmaceutical manufacturers, but also improves the efficiency of use.

Pre-filling is mainly divided into two types of cone head type and spiral head type: cone head type consists of tube sleeve, cone head cap, piston and push rod; spiral head type consists of glass needle tube, screw head cap, screw head, piston and Putter composition.

Plastic syringe filling process:

A semi-automatic filling machine is used to fill a fixed amount of medicine in a needle tube (with a cap), and the piston is pressed or screwed in to seal the medicine liquid, and then a push rod is added for packaging.

Another way is tube with cap and then filling from the bottom of the tube.

How to solve the sealing of veterinary syringe

Veterinary syringe should be able to have a good seal during the validity period of the drug, prevent the invasion of microorganisms and cause deterioration of the drug, thereby posing danger to users. The best solution to verify the pre-sealing of pet medicine packaging is to test the integrity of the seal bottle by bottle.

The internationally accepted quality assurance process based on the design of the container sealing system, the production of sealing components, the completion of the sealing, and the verification of the integrity of the sealing, thereby ensuring the tightness of the finished product. Then the main factors affecting the sealability of the syringe of pet medicine packaging are the following:

First, the design of the sealing system is defective, resulting in a leak that cannot meet the requirements;

Second, there is a quality deviation in the container or sealed component;

Third, there are problems with the sealing process;

Fourth, the seal integrity verification scheme is unreasonable;

The solution is as follows:

Aiming at the problem of the design defect of the plastic syringe and sealing system for pet medicine packaging, a rigorous design scheme should be formulated in advance, and as far as possible, the use of sealing members in accordance with international standards can effectively avoid the risk of leakage.

For the problem of containers and sealed components, suppliers of rubber stoppers and pet medicine packaging pre-filling should be regularly audited to ensure their quality is stable and reliable.

For problems in the sealing process, a sampling test plan should be formulated to standardize the sealing process.

As the seal integrity verification scheme is unreasonable, the integrity of the seal system should be verified.
