Description

Technical Field

[0001] This utility model belongs to the field of film bag technology, and in particular relates to a pharmaceutical packaging film bag. Background Technology

[0002] Compound calamine lotion's main ingredients are calamine and zinc oxide. It is a topical chemical preparation, a pink suspension, with astringent and skin-protecting properties, suitable for acute itchy skin diseases such as urticaria and prickly heat. Currently, compound calamine lotion is packaged in bottles; it is poured into a saucer and then applied to the affected area using a medical cotton swab. This application method is cumbersome as it requires additional tools. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a pharmaceutical packaging film bag that is easy to apply and can prevent leakage of compound calamine lotion.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a pharmaceutical packaging film bag, comprising a film bag body and an anti-drip coating nozzle;

[0005] The anti-drip coating nozzle consists of a nozzle sleeve, a leak tube, a first retaining ring, a spring, a plug, a protective cap, and a tube sleeve. The nozzle sleeve is integrally formed from a cylindrical section and a disc section. The opening of the leak tube is heat-fused and sealed to the cylindrical section of the nozzle sleeve. The disc section of the nozzle sleeve rests against the outer end face of the opening of the membrane bag body. The plug is fixedly and sealed and embedded in the inner end of the cylindrical section. The tube sleeve is fixedly sleeved and installed on the outer end of the leak tube. The first retaining ring is fixedly sleeved and installed on the inner end of the leak tube. The top of the leak tube is set as a plug structure. The leak tube is slidably sealed and installed in the plug. The leak tube is also provided with an inlet hole. The spring is sleeved and installed on the leak tube. The upper and lower ends of the spring act on the plug and the tube sleeve respectively. The first retaining ring contacts the top of the plug to limit the downward movement limit of the leak tube. The disc section has external threads. The protective cap is screwed onto the disc section.

[0006] Preferably, the outer surface of the cylindrical section is provided with several concentric grooves.

[0007] Preferably, a second retaining ring is fixedly provided on the inner wall of the protective cover.

[0008] Preferably, the sealing screw is fixed and embedded in the inner end of the cylindrical section.

[0009] Compared with existing technologies, the advantages of this invention are: the pharmaceutical packaging film bag allows for direct application of compound calamine lotion to the affected area without the need for other tools, making it convenient to use. Compared to plastic or glass bottles, the film bag has lower operating costs and can be squeezed to accelerate the flow of the compound calamine lotion, improving application efficiency. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Figure 1 This is a diagram of the internal structure of this utility model.

[0012] Figure 2 yes Figure 1 Enlarged structural diagram at point M. Detailed Implementation

[0013] The present invention will now be described in detail with reference to specific embodiments:

[0014] like Figure 1 and Figure 2 The pharmaceutical packaging film bag shown includes a film bag body 1 and an anti-drip coated nozzle;

[0015] The anti-drip coating nozzle consists of a nozzle sleeve 2, a leakage tube 3, a first retaining ring 32, a spring 4, a sealing plug 5, a protective cap 6, and a tube sleeve 7. The nozzle sleeve 2 is integrally formed from a cylindrical section 21 and a disc section 22. The opening of the leakage tube 3 is heat-fused and sealed to the cylindrical section 21 of the nozzle sleeve 2. The disc section 22 of the nozzle sleeve 2 abuts against the outer end face of the opening of the membrane bag body 1. The sealing plug 5 is fixedly and sealed and embedded in the inner end of the cylindrical section 21. The tube sleeve 7 is fixedly sleeved on the outer end of the leakage tube 3. The first retaining ring 3... 2. A fixed sleeve is installed inside the leaking pipe 3. The top of the leaking pipe 3 is set as a sealing structure. The leaking pipe 3 is slidably sealed and installed inside the sealing plug 5. The leaking pipe 3 is also provided with an inlet hole 31. The spring 4 is sleeved and installed on the leaking pipe 3. The upper and lower ends of the spring 4 act on the sealing plug 5 and the pipe sleeve 7 respectively. The first retaining ring 32 contacts the top of the sealing plug 5 to limit the downward movement limit position of the leaking pipe 3. The disc section 22 has external threads. The protective cover 6 is screwed and installed on the disc section 22.

[0016] Several grooves 210 are provided on the outer surface of the cylindrical section 21. When the film bag body 1 is hot-melted, the material at the opening melts into the grooves 210, making the film bag body 1 and the mouthpiece 2 more secure.

[0017] A second retaining ring 61 is fixedly provided on the inner wall of the protective cover 6, which can limit the tightness of the protective cover 6 and prevent the protective cover 6 from contacting the sleeve 7 and causing leakage.

[0018] The sealing plug 5 is screwed in and fixedly embedded in the inner end of the cylindrical section 21, which has the advantages of convenient and firm installation.

[0019] The compound calamine lotion is encapsulated inside the membrane bag body 1. The spring 4 pushes the combination of the leakage tube 3 and the sleeve 7 to move outward until the first retaining ring 32 contacts and limits the sealing 5. The liquid inlet 31 is located inside the sealing 5 and is blocked by it. At this time, the leakage tube 3 is in a blocked state, so there will be no leakage problem.

[0020] When applying the product, first shake the main body 1 of the film bag to homogenize the compound calamine lotion, then unscrew the protective cap 6. Hold the main body 1 of the film bag and press the tube sleeve 7 against the affected area. The combination of the tube sleeve 7 and the leakage tube 3 will overcome the elastic force of the spring 4 and move upward. The inlet hole 31 of the leakage tube 3 will extend out from the top of the seal 5. Squeeze the main body 1 of the film bag tightly to allow the compound calamine lotion to quickly enter the leakage tube 3 through the inlet hole 31 and flow out of the tube sleeve 7 to the affected area for application. A cotton ball can be inserted into the end of the tube sleeve 7 to improve the application effect and comfort.
