[0025] The invention discloses a vial cap, which reduces the difficulty of sealing the vial; the invention also provides a vial.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 6 As shown, Figure 1 An exploded view of the assembly structure of the vial cap and the vial provided by the present invention; Figure 2 for Figure 1 Top view of the cap of the vial of Cialis; Figure 3 for Figure 1 Bottom view of the cap of the vial of Cialis; Figure 4 for Figure 1 A longitudinal cross-sectional view of the cap of a vial of Zhongxilin; Figure 5 for Figure 1 Schematic diagram of the assembly structure of the cap and gasket of the vial of Zhongxilin; Figure 6 for Figure 1 Cross-sectional view of the assembly structure of the vial cap and vial.

[0028] The present embodiment provides a vial cap, comprising a cover portion 11 covered on the vial mouth 5; a plurality of buckle portions 12 located at the edge of the cover portion 11 and extending along the thickness direction thereof; a claw 14 extending from the lower edge of each buckle portion 12 for buckling with the vial mouth. When the vial cap 1 is mounted on the vial mouth 5, the claw 14 end of the buckle part 12 is supported by the outer wall of the vial mouth 5, and as the cover part 11 is installed, the claw 14 end extends into the lower end of the vial mouth 5, and the extension length of the buckle part 12 is consistent with the height of the vial mouth 5, ensuring that the claw 14 is clamped with the lower end of the vial mouth 5, and the buckle part 12 is mounted on the outer wall of the vial mouth 5, and the cover part 11 presses the rubber gasket 2 of the vial mouth 5 to achieve the sealing of the vial mouth 5. By adopting the buckle-mounted vial cap 1, the vial sealing 5 and the vial cap 1 are assembled by press-fitting, the installation structure is simple, and the sealing difficulty is low.

[0029] In a specific embodiment of the present case, the cover-mounting portion 11 is a cover-mounting portion of a disc-shaped structure, and a plurality of buckle-mounting portions 12 are evenly arranged along the edge of the cover-mounting portion 11. To adapt to the bottle mouth structure of the vial 3, a rubber gasket 2 is also arranged between the vial cap 1 and the vial mouth 5. To ensure the safety of the rubber gasket 2, the cover-mounting portion 11 is set to a disc-shaped structure, and a plurality of buckle-mounting portions 12 are evenly distributed on the edge of the cover-mounting portion 11 of the disc-shaped structure, thereby improving the stability of the press-fitting structure of the rubber gasket 2 and ensuring the safety of the liquid in the vial.

[0030] In a specific embodiment of the present case, an arc-shaped connecting portion 13 is provided at the lower edge of any two adjacent buckling portions 12 to connect the two. The adjacent buckling portions 12 are composed of the arc-shaped connecting portion 13, that is, the capping end of the vial cap 1 is an annular structure. When the vial cap 1 is installed into the vial mouth 5, the claw 14 opens and the arc-shaped connecting portion 13 is opened at the same time. After the vial cap 1 is installed, the arc-shaped connecting portion 13 pulls the buckling portions 12 to avoid the single buckling portion 12 being disengaged due to force, thereby ensuring the capping safety of the vial cap 1.

[0031] In a specific embodiment of the present case, the inner circle of the buckle part 12 is an arc-shaped buckle surface that fits the outer wall of the vial mouth 5. The buckle part 12 extends from the edge of the cover part 11, and the inner circle of the buckle part 12 is provided with an arc-shaped buckle surface, which is tightly attached to the outer wall of the vial mouth 5, and the cover is stable. The outer circle of the buckle part 12 can be set as a curved surface structure, and can also be set as a special-shaped structure according to the positioning or placement requirements to meet the use requirements of bottles of different materials.

[0032] In a specific embodiment of the present case, the inner diameters of the inner circles of the arc-shaped connecting portion 13 and the buckling portion 12 are the same. The inner diameters of the inner circles of the arc-shaped connecting portion 13 and the buckling portion 12 are the same, and the wall thickness of the outer circle can be controlled according to the stability of the connection structure and the difficulty of opening the buckling portion when buckled onto the mouth of the vial, so as to ensure smooth installation and reduce the difficulty of installation.

[0033] Preferably, the buckle parts 12 include three buckle parts 12 evenly distributed on the edge of the cover part. The three buckle parts 12 are distributed at an angle of 120° to each other, and the structure is stable and easy to buckle. The width of the buckle part can be designed according to different specifications of the vial, ensuring stable connection while reducing material usage.

[0034] In a specific embodiment of the present case, a puncture hole 4 is pre-set on the cover 11. The liquid in the vial 3 needs to be taken out with an infusion tube or a needle, and a puncture hole 4 is reserved in the middle of the cover 11, and multiple puncture holes can also be reserved as needed to improve the convenience of use.

[0035] In a specific embodiment of the present case, a gasket 2 is pre-installed between the multiple buckle parts 12, which fits with the cover part 11 and seals the vial mouth 5. Since the vial cap 1 and the vial 3 adopt a buckle-fitting structure, the rubber gasket 2 used to seal the vial mouth 5 can be pre-installed in the vial cap 1. Specifically, the outer side of the rubber gasket 2 fits with the inner side of the cover part 11, and the loading end of the rubber gasket 2 extending into the vial mouth 5 can be loaded at once after the buckle part is installed. The vial cap 1 and the rubber gasket 2 are assembled with the vial as a whole, which optimizes the process and improves safety.

[0036] In a specific embodiment of the present case, the cover portion 11, the buckle portion 12 and the arc-shaped connecting portion 13 are integrally injection-molded from a plastic material. The vial cap 1 is made of plastic material, and the cover portion, the buckle portion and the arc-shaped connecting portion are integrally injection-molded. The plastic material is flexible plastic, which ensures stable buckle installation and avoids breakage during the insertion process of the vial.

[0037] Based on the vial cap provided in the above embodiment, the present invention further provides a vial, comprising a vial body and a vial cap mounted on the vial body, wherein the vial cap provided on the vial body is the vial cap provided in the above embodiment.

[0038] Since the vial adopts the vial cap of the above embodiment, please refer to the above embodiment for the beneficial effects brought by the vial cap of the vial.

[0039] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
