The present invention relates to a vial cap, and more particularly, to a vial cap that can simplify the sealing process of the vial and reduce the defective rate of the vial.

Generally, a vial refers to a vial or a container for keeping internal storage materials such as contact lenses and other chemical liquids such as contact lenses and sterilization, and to prevent leakage and deterioration of contents in storage and It is sealed to block foreign substances from entering, and it is formed in various forms to be safely stored and transported.

The conventional vial is formed of a sterile, antibacterial glass material or a plastic material that has passed the prescribed medicine container test method, as shown in Figure 1, the vial bottle 10 having a space to store the contents therein, and It consists of the rubber field 20 which seals the opening part of the bottle 10, and the vial cap 30 which wraps the outer side of the rubber field 20. As shown in FIG.

Here, the vial cap 30 is composed of a cover 31 made of a synthetic resin to form an upper layer of the cap, and a sleeve 32 made of metal to form a lower layer of the cap, and a central portion of the cover 31. It is fixed to each other by the coupling portion 33 extending downward in the. In addition, the cutting line 34 is formed on the surface of the sleeve 32 so as to easily cut when the cover 31 is peeled off, and the bridge 35 is formed at a predetermined interval on the cutting line 34.

And, the rubber field 20 is made of a different diameter so that the lower end and the upper end end, the lower end is made of a diameter smaller than the inner diameter of the opening to fit the inner diameter of the opening of the vial bottle 10, the upper end of the vial bottle (10) ) And have a diameter that is equal to or slightly smaller than the inner diameter of the sleeve 32 to cover the opening and fit within the sleeve 32. That is, the upper end of the rubber field 20 is inserted into the inner diameter of the vial cap 30, and the lower end is fitted to the opening of the vial bottle 10, thereby reducing the friction force generated between the vial cap 30 and the vial bottle 10. Reduce and increase the sealing force.

The vial having this configuration is sealed by inserting the contents into the vial bottle and then inserting a rubber field into the opening of the vial bottle. Then, the vial cap is put on the outside of the rubber field and the lower end of the sleeve positioned around the opening is clamped and sealed, and then the contents are sterilized. In this case, as shown in FIG. 2, when the contents are contact lenses, steam sterilization is performed at 121 ° C. for 20 minutes. Due to the internal pressure of the vial bottle, the rubber field is pushed upward, and the pressure of the internal pressure pushing the rubber field is increased. The deformation of the sleeve and the breakage of the bridge by the force occurs, which causes a failure of the vial.

In addition, if the strength of the bridge is strengthened to prevent the bridge from boiling, the bridge does not break well despite the pushing force of the internal pressure, but when the end consumer removes the vial cap, the bridge strength is too strong and does not break easily. Due to this, only the plastic cover is removed from the state in which the sleeve is not cut off, which causes difficulty in opening.

In addition, the sealing process of the vials that puts the contents into the vial bottles, seals the rubber pads in the openings of the vial bottles, seals them, covers the vial caps on the outside of the rubber pads, and clamps the lower end of the sleeves located around the openings. There is a problem in that the productivity is poor.

As shown in Table 1, as a result of experimenting with 1000 vials, in the case of Experiment 1, two broken defects of the bridge 322 during sterilization treatment, defects in the cutting direction of the bridge 322 when the vial was opened, and the cover 310 were The number of defects was the smallest, with two missing defects. In the case of Experiment 2, the strength of the bridge 322 was strong and the seal phenomena of the seal member 340 were weak, so that no defects during sterilization were generated. However, the strength of the bridges was strong. . In addition, in the case of Comparative 1, the strength of the bridge was weak during sterilization, so the number of defects of the vials that broke the bridge was pushed up due to the internal pressure of the vial bottle. It was like one. In addition, in the case of Comparative 2, the strength of the bridge is strong, so that even if the rubber field is pushed up due to the internal pressure of the vial bottle, the number of failures of breaking the bridge is smaller than that of Comparative 1, but the number of failures of the cover being removed when the vial is opened is large. .

As can be seen from the test results, the vial cap of the present invention is when the internal pressure of the vial bottle is applied to the seal member due to the recessed groove formed in the upper surface of the seal member, even if the bridge strength of the sleeve is weakened so that consumers can easily separate it. The bottom portion of the thin indented groove is indented to the upper side of the indented groove to further secure a predetermined space inside the vial bottle, thereby buffering the internal pressure, and also the seal member is fixed to the inner wall of the sleeve so that the inside of the vial bottle Not being pushed up by the pressure does not cause deformation in the sleeve and prevents the bridge from breaking, thereby reducing the failure rate. In addition, the vial is easily opened as the bridge's strength of the sleeve is weak.

In addition, the vial cap of the present invention is a sealing process is made by sealing the opening of the vial bottle with the vial cap by the seal member is integrated with the sleeve. In addition, by eliminating the need for a conventional rubber field, it is possible to reduce the cost of the raw materials and to improve productivity by shortening the process.
