[0026] Please see Figure 1 As shown, this embodiment provides an aseptic filling cap for vials, which is affixed to the vial body 1. The aseptic filling cap includes a first shell 2, a second shell 3, a rubber stopper 4, and a third shell 5, wherein:

[0027] The first housing 2 is a double-opening cylindrical shape. The inner wall of the first housing 2 is provided with a claw 6, which is used to hold the neck of the vial body 1.

[0028] The second housing 3 is a single-opening cylindrical shape. The open end of the second housing 3 is fitted onto the first housing 2 and is press-fitted with the first housing 2. A puncture port 7 is provided on the closed end of the second housing 3.

[0029] The rubber stopper 4 is sandwiched between the first housing 2 and the second housing 3, and the rubber stopper 4 is used to seal the mouth of the vial body 1;

[0030] The third housing 5 is a single-opening cylindrical shape. The open end of the third housing 5 is fitted onto the second housing 3 and threadedly connected to the second housing 3. The third housing 5 is used to close the puncture port 7.

[0031] Thus, by using the claws 6 of the first housing 2 to snap onto the vial body 1, by using the interference fit between the second housing 3 and the first housing 2 to clamp the rubber stopper 4, and by using the threaded connection between the third housing 5 and the second housing 3, simple manual compression capping of the vial is achieved, ensuring that the filled medicine is in a sterile environment, avoiding contamination, and making the filling process more convenient.

[0032] Optionally, the rubber stopper 4 is made of TPE material and can be laser-sealed after puncture.

[0033] Therefore, the TPE stopper 4 possesses excellent flexibility and elasticity, ensuring that it maintains its sealing performance after puncture and laser sealing, preventing drug leakage.

[0043] 1) The first housing 2 and the second housing 3 are interference-fitted, and the rubber plug 4 is clamped in them;

[0044] 2) The second housing 3 and the third housing 5 are threaded together to seal the puncture port 7;

[0045] 3) The claws 6 of the first housing 2 are used to hold the neck of the vial body 1;

[0046] 4) Unscrew off the third housing 5, and fill the rubber plug 4 through the puncture port 7 (while simultaneously venting air);

[0047] 5) Laser seal the puncture hole of the rubber stopper 4;

[0048] 6) Screw the third housing 5 back on to seal the puncture port 7 and protect the puncture surface of the rubber stopper 4 from contamination.

[0049] In summary, this aseptic filling cap for vials has the following advantages:

[0050] 1) The crimped cap does not shed any aluminum shavings, thus avoiding contamination of the cleanroom environment and vials;

[0051] 2) Uniformity and stability of capping are achieved by relying on the product's size design, eliminating the need for capping equipment;

[0052] 3) The manual compression molding and capping process is simple, bringing more convenience to small-batch drug production;

[0053] 4) The TPE rubber stopper allows for repeated puncture filling and laser sealing, ensuring the sterility of the medicine;

[0054] 5) The third housing 5 is detachably connected to the second housing 3 to ensure that the puncture surface of the rubber stopper 4 is sterile.
