DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0031] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0032] The present application embodiment discloses a film cover, referring to Figures 1 to 3 , comprising a cover body 1, a plug element 2 and a tear film sheet 3. A cavity is provided inside the cover body 1 to form an inner cavity. The cover body 1 comprises three integral parts from top to bottom, namely an upper cover portion 11, a lower cover portion 12 and a reinforcement flange 13. The reinforcement flange 13 is fixedly provided on the outer wall of the lower cover portion 12 on the side away from the upper cover portion 11. The reinforcement flange 13 is provided as a thickened layer at the bottom of the lower cover portion 12. The reinforcement flange 13 is used to improve the overall strength of the cover body 1 and prevent the cover body 1 from deformation. The diameters of the upper cover portion 11, the lower cover portion 12 and the reinforcement flange 13 increase successively, giving the cover body 1 a three-step appearance. This arrangement can improve the aesthetics and usability of the cover body 1.

[0033] The tear film sheet 3 is fixedly bonded to the top of the upper cover part 11 through the film pressing process. In order to improve the fixing tightness of the tear film sheet 3, two limiting protrusions 113 are integrally opened at one end of the upper cover part 11 away from the lower cover part 12. The two limiting protrusions 113 are symmetrically distributed along the length direction of the upper cover part 11. The setting of the limiting protrusions 113 forms a groove on the top of the upper cover part 11. The tear film sheet 3 is clamped in the groove by the limiting protrusions 113 on both sides and then fixed by the film pressing process, which can prevent the tear film sheet 3 from deflecting. The setting of the limiting protrusions 113 can also cooperate with the film pressing equipment to achieve the technical effect of positioning, thereby improving the success rate of one-time film pressing of the tear film sheet 3.

[0034] The side of the upper cover 11 is provided with a fitting surface 114, which is configured as an inclined surface extending downward from the top of the upper cover 11 along the side of the upper cover 11. The two fitting surfaces 114 are symmetrically arranged and form a gap between the two limiting protrusions 113. Adhesive ears 31 are integrally provided at both ends of the tear film sheet 3. The adhesive ears 31 are fixedly bonded to the fitting surface 114 through a film pressing process. The fitting surface 114 extends from the top of the upper cover 11 toward the lower cover 12. The fitting surface 114 is narrowed, that is, the closer the fitting surface 114 is to the lower cover 12, the narrower its width. This configuration can adapt to the stress when the adhesive ears 31 are bent, and prevent the adhesive ears 31 from breaking when they are bent and attached to the fitting surface 114. The setting of the bonding ear 31 makes it convenient for the operator to tear off the tearing sheet 3 by holding the bonding ear 31. In order to make the tearing process of the tearing sheet 3 smoother, a plurality of bonding handles 115 are provided on the surface of the bonding surface 114. In the embodiment of the present application, each bonding surface 114 is fixedly provided with two bonding handles 115, and the bonding handles 115 are vertically arranged. The bonding handles 115 are provided with a wide end face and a narrow end face, the wide face faces the top of the upper cover portion 11, and the narrow face faces the lower cover portion 12. When the bonding ear 31 is fixedly bonded to the bonding surface 114, the setting of the bonding handles 115 can form a spacing gap between the bonding ear 31 and the bonding surface 114, thereby making it easy to tear off the tearing sheet 3.

[0035] Reference Figure 4 and Figure 5 A filling groove 112 is provided downwardly at the top of the upper cover portion 11. In order to facilitate the removal of medicine through a needle, the bottom of the filling groove 112 extends into the inner cavity. The filling groove 112 can also prevent the liquid medicine from coming into contact with the rubber plug 24 for a long time. The rubber plug element 2 is arranged in the filling groove 112. The rubber plug element 2 is molded with the cover body 1 at one time by two-color glue injection. The filling groove 112 is opened according to the shape of the rubber plug element 2. The rubber plug element 2 includes a filling handle 23. Two pinhole grooves 22 are provided at the top of the filling handle 23 at intervals. Two rubber plugs 24 are fixedly provided at the bottom of the filling handle 23 corresponding to the position of the pinhole grooves 22. The rubber plug 24 is integrally provided with the filling handle 23. The pinhole groove 22 is used to reserve a puncture position for the needle. The pinhole groove 22 is sealed by the tear film 3. In order to improve the sealing effect of the pinhole groove 22 and prevent the pinhole groove 22 from being contaminated, an annular protrusion is provided on the circumferential side of the pinhole groove 22 to form a sealing ring 21. The setting of the sealing ring 21 can increase the surface area of ​​the top of the filling handle 23. When the tear film 3 is fixed, it is blocked by the sealing ring 21 and then bent, thereby increasing the contact area between the tear film 3 and the filling handle 23 and improving the anti-fouling effect.

[0036] The bottom of the filling tank 112 matches the plug 24 and is provided with two grooves to form a plug slot 111, which is used to install the plug 24. The two plugs 24 are independently installed in the two plug slots 111 to avoid cross contamination between the two plugs.

[0037] The implementation principle of this application is as follows: According to the utility model, a film cap is suitable for bottle openings of any size and includes a cap body 1, a plug element 2, and a tear film sheet 3. During actual operation, medical personnel grasp the adhesive ear 31 and gently pull to tear off the tear film sheet 3. This process does not require the use of other tools and is both convenient and quick. Subsequently, a needle can be inserted to remove or dispense medicine. The provision of the tear film effectively avoids contamination of the bottle cap. At the same time, the use of two independent plugs 24 and plug grooves 111 can provide two independent needle insertion ports, avoiding cross contamination during use, ensuring both sealing and anti-fouling properties and improving ease of use.

[0038] The above-described embodiments merely represent implementation methods of the utility model. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the utility model, and these modifications would fall within the scope of protection of the utility model. Therefore, any equivalent changes based on the structure, shape, and principle of the present application would be encompassed within the scope of protection of the present application.
