Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hermetic closure device for a vial mouth, and more specifically, it does not require winding and tightening with an aluminum cap to seal the vial mouth, and the rubber stopper is not exposed during use. The present invention relates to an easy closure device for a vial mouth.

[0002]

2. Description of the Related Art Conventionally, the mouth of a vial containing a freeze-dried preparation is hermetically closed by closing the mouth of the vial with a rubber stopper and further covering the aluminum cap with an aluminum cap. However, it is necessary to use the drug after the aluminum cap is peeled off and the sealed vial is pierced with the aluminum cap, and the solution is injected by inserting the injection needle into the rubber stopper to dissolve the drug inside. (Alternatively, it is necessary to remove the rubber stopper and put the solution inside to dissolve the drug inside and use the drug.)
Since the aluminum cap is made of metal, it may be injured by catching with your hands, etc., and after use, it is necessary to separate and discard the aluminum, which is a drawback.

Therefore, as a solution to the above-mentioned drawbacks, the present inventors have a cap outer frame having a skirt and a top surface, and a skirt and a top surface having a through hole. It is composed of a formed cap inner frame and a rubber plug having a flange and a leg. The rubber plug has the leg inserted into the through hole of the cap inner frame and the flange. The cap outer frame is held so as to be positioned between the cap outer frame and the cap inner frame, the cap outer frame is slidable along the outer wall of the skirt of the cap inner frame, and the cap outer frame is We have already proposed a vial cap that is configured so that when it slides down along the skirt, the inner frame of the cap is pressed by the outer frame of the cap to deform inward and engage with the flange of the mouth of the vial. (Special No. flat 5-353241). However, this vial cap is for removing the entire cap, not for exposing the top surface of the rubber stopper,
It has the disadvantage of requiring a relatively high force to remove the cap.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and does not require winding and tightening with an aluminum cap when sealing the mouth of a vial, and the rubber stopper is exposed during use. It is an object of the present invention to provide a hermetic closure device for a vial opening that is easy to operate.
