[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0025] Please see Figure 1 As shown, this embodiment provides a cartridge bottle compression cap, which is affixed to a cartridge bottle. The cartridge bottle compression cap includes a first housing 2, a second housing 3, and a gasket 4, wherein:

[0026] The first housing 2 is a double-opening cylindrical shape. The inner wall of the first housing 2 is provided with a claw 5, which is used to hold the neck of the cartridge bottle body 1.

[0027] The second housing 3 is a single-opening cylindrical shape. The open end of the second housing 3 is interference-fitted onto the first housing 2, and a puncture port 6 is provided on the closed end of the second housing 3.

[0028] The gasket 4 is sandwiched between the first housing 2 and the second housing 3, with one side of the gasket 4 abutting against the mouth of the cartridge bottle 1 and the other side of the gasket 4 abutting against the puncture port 6.

[0029] Thus, by using the claws 5 of the first housing 2 to snap onto the bottle body 1, and by using the second housing 3 to clamp the gasket 4 in an interference fit with the first housing 2, simple manual compression molding and capping of the bottle is achieved, reducing the difficulty of capping and bringing more convenience to the use of the bottle.

[0030] Optionally, the claw 5 is integrally formed with the first housing 2, and the claw 5 is in the shape of an annular plate and is arranged at an angle of 45° toward one side of the gasket 4.

[0031] Therefore, the 45° angled claw 5 facilitates the insertion and securing of the bottle neck 1 into the cartridge bottle body 1, while ensuring even force distribution on the gasket 4, thus improving the sealing effect. The cartridge bottle compression cap has a compact overall structure, is easy to operate, and is suitable for various sizes of cartridge bottles, greatly improving efficiency and safety.

[0032] Furthermore, the diameter of the claw 5 is smaller than the diameter of the mouth of the cartridge bottle body 1 but larger than the diameter of the neck of the cartridge bottle body 1.

[0033] Therefore, the claw 5 fits tightly with the mouth of the cartridge bottle 1 to prevent loosening and ensure the airtightness of the contents inside the bottle.

[0034] Optionally, the gasket 4 is frustum-shaped, with the larger circular surface of the gasket 4 facing the claw 5 and the smaller circular surface of the gasket 4 facing the puncture site 6.

[0035] Therefore, the frustum design of gasket 4 effectively disperses pressure, enhances the sealing effect, and extends service life.

[0036] Optionally, the material of the first housing 2 is ABS, PC, COC, COP, CBC, etc. These materials can greatly increase the strength of the claw 5 in engaging with the cartridge bottle and greatly improve the sealing performance of the cartridge bottle cap.

[0037] Optionally, the second shell 3 can be made of materials such as COC, COP, CBC, or PP. These materials have good heat resistance and impact resistance, ensuring stable performance under high temperature or high pressure conditions, and further improving the durability and safety of the overall structure.

[0038] Optionally, the gasket 4 is made of polyisoprene rubber, halogenated butyl rubber, or a combination of the two. These materials not only ensure the durability and chemical stability of the compression-molded cap, but also further improve the overall sealing performance, adapt to storage needs in different environments, and ensure the safety and freshness of the contents of the bottle.

[0039] In summary, this cartridge bottle compression cap has the following advantages:

[0040] 1) The crimped cap does not shed any aluminum shavings, thus avoiding contamination of the cleanroom environment and the cartridge bottle body;

[0041] 2) Uniformity and stability of capping are achieved by relying on the product's size design, eliminating the need for capping equipment;

[0042] 3) The manual compression molding and capping process can be easily completed, bringing more convenience to small-batch drug production.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
