Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medicine bottles, in particular to a sealed and puncture-proof medicine bottle. Background Art
[0002] A medicine bottle is a container for holding medicines. Currently, a sealing film structure is generally adhered to the opening of the medicine bottle. The sealing film structure includes a polyethylene bottom layer and an aluminum foil surface layer. The sealing film structure is fixedly adhered to the end of the opening of the bottle body through the circumferential end of the polyethylene bottom layer. However, within a certain period of time or during a long storage time, the adhesion effect at the adhesion part will be reduced, and small gaps are likely to appear, thereby reducing its sealing effect. Or when the user accidentally squeezes the sealing film structure under the action of external force during non-use, it may also cause the adhesion part to tear open, resulting in small gaps. In addition, when the thicknesses of the polyethylene bottom layer and the aluminum foil surface layer are small, it is easy for the user to pierce them during non-use (such as during the collision process or under the action of hard spines), so that the user has to use the medicine immediately. In this way, the overall use effect of the medicine bottle will be greatly reduced. Based on this, we propose a sealed and puncture-proof medicine bottle. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the utility model provides a sealed and puncture-proof medicine bottle. After improvement, the medicine bottle can effectively solve the problems raised in the above background art.
[0004] The technical solution of the utility model is as follows: [[ID= seventeen]]

The sealing film structure is sequentially provided with a base layer, a first puncture-proof layer, a second puncture-proof layer, a third puncture-proof layer and a surface layer from bottom to top. A circular groove is arranged on the inner wall of the opening of the bottle body. A convex ring adapted to the circular groove is arranged on the bottom surface of the base layer. The sealing film structure is adhesively bonded in the circular groove through the convex ring being embedded.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] The following further describes the specific implementation manners of the present utility model in conjunction with the accompanying drawings:
[0024] As Figures 1-4 shown,
[0025] A sealed and puncture-proof medicine bottle includes a bottle body 1 and a sealing film structure 2. A sealing film structure 2 is provided at the opening of the bottle body 1. The sealing film structure 2 is sequentially provided with a base layer 3, a first puncture-proof layer 4, a second puncture-proof layer 5, a third puncture-proof layer 6, and a surface layer 7 from bottom to top. An annular groove 8 is provided on the inner wall of the opening of the bottle body 1. A convex ring 9 adapted to the annular groove 8 is provided on the bottom surface of the base layer 3. The sealing film structure 2 is embedded and bonded in the annular groove 8 through the convex ring 9. The base layer 3, the first puncture-proof layer 4, the second puncture-proof layer 5, the third puncture-proof layer 6, and the surface layer 7 are all fixed by bonding to each other. In this embodiment, by providing the annular groove 8 and the convex ring 9, after the sealing film structure 2 is bonded to the bottle body 1, there are three bonding points. Even if there is a gap in the bonding at one of them, it can still be sealed through the other two bonding points, so that the sealing effect is better. In addition, by providing the first puncture-proof layer 4, the second puncture-proof layer 5, and the third puncture-proof layer 6 between the base layer 3 and the surface layer 7, it will not affect the use of the sealing film structure 2, and moreover, it makes it have strong puncture-proof performance, greatly improving the use effect. It should be noted that the thicknesses of the first puncture-proof layer 4, the second puncture-proof layer 5, and the third puncture-proof layer 6 are the same, which is one-fifth of the thickness of the base layer 3. The purpose is to increase the puncture-proof effect while not excessively increasing the thickness of the sealing film structure 2 as a whole. It is also possible to reduce the thickness of the base layer 3 on the basis of the existing base layer 3. The reduced part can be the same as the sum of the thicknesses of the three puncture-proof layers, so as to ensure that the thickness of the sealing film structure 2 is the same as the original thickness.
[0026] As a preferred implementation manner; the annular groove 8 is a stepped structure; it can be understood that it has a horizontal plane and a vertical plane, increasing the bonding sites with the sealing film structure 2, thereby improving the sealing performance after the sealing film structure 2 is bonded.
[0027] As a preferred implementation manner; the bottom surface of the convex ring 9 is fixedly bonded to the horizontal plane of the annular groove 8, the outer side surface of the convex ring 9 is fixedly bonded to the vertical plane of the annular groove 8, and the bottom end of the base layer 3 is fixedly bonded to the end of the opening of the bottle body 1; it can be understood that the horizontal plane is the first bonding point, the vertical plane is the second bonding point, and the bottom end of the base layer 3 and the opening of the bottle body 1 are the third bonding point, making it have an excellent sealing effect after bonding.
[0028] It is worth mentioning that although bonding sites are added in this application, when tearing the sealing film structure 2, it is still not very strenuous. After all, the thickness, volume and area of the sealing film structure 2 are all small, and tearing the small film is quite easy for normal users.
[0029] As a preferred embodiment; a bottle mouth 10 is provided at the top of the bottle body 1, an external thread is provided on the outer wall of the bottle mouth 10, and a bottle cap 11 is threadedly connected to the bottle mouth 10 through the external thread; by providing the bottle cap 11, on the one hand, the sealing performance of the medicine bottle is increased, on the other hand, when using this medicine bottle, drug leakage can be avoided, and on the third hand, the sealing film structure 2 can also be protected.
[0030] As a preferred embodiment; the bottle body 1 and the bottle mouth 10 are of an integrally formed structure, the materials of the bottle body 1 and the bottle mouth 10 are both glass, and the material of the bottle cap 11 is plastic.
[0031] As a preferred embodiment; the base layer 3 and the convex ring 9 are of an integrally formed structure, and the base layer 3 is a polyethylene layer.
[0032] As a preferred embodiment; the first puncture-proof layer 4 is an aramid fiber layer. Aramid fiber has the characteristics of light weight and good flexibility, and moreover, it also has excellent puncture-proof performance.
[0033] As a preferred embodiment; the second puncture-proof layer 5 is an LLDPE layer; the third puncture-proof layer 6 is an HDPE layer; both LLDPE and HDPE materials have strong toughness, impact resistance and tensile strength, making them have better puncture resistance. Combined with the first puncture-proof layer 4, the overall puncture-proof effect of the sealing film structure 2 is better.
[0034] As a preferred embodiment; the surface layer 7 is an aluminum foil layer; using aluminum foil has certain moisture-proof performance and certain sealing performance, which can improve the use quality of the sealing film structure 2.
[0035] It should be pointed out that the main problems in the prior art are: the sealing effect of the sealing film structure on the medicine bottle is poor, and it is easy to be punctured;
[0036] Therefore, after the improvement of the present application, a circular groove 8 is provided on the bottle body 1, and a convex ring 9 adapted to the circular groove 8 is provided on the bottom surface of the base layer 3. After the sealing film structure 2 is adhesively fixed to the bottle body 1, its sealing effect is excellent, thereby effectively preventing problems such as cracking or gaps at the adhesive joint between the bottle body 1 and the sealing film structure 2 due to various situations, thus greatly improving the sealing effect of the sealing film structure 2 and further enhancing the use effect and quality of the medicine bottle. In addition, by providing a first puncture-proof layer 4, a second puncture-proof layer 5 and a third puncture-proof layer 6 on the sealing film structure 2, the puncture-proof ability of the sealing film structure 2 can be effectively enhanced. Even if the thickness of the base layer 3 is reduced, its puncture-proof effect can still be ensured, thereby avoiding the problem that the sealing film structure 2 is punctured due to the user's misoperation, forcing the user to immediately use the medicine, and thus greatly improving the overall use effect of the medicine bottle.
[0037] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
