At the same time, the surface side of the circular flexure 11 is
Although the seal portion C in a surface contact state is formed by pressure contact with the tip end surface 21 of the container 20, the circular press-fitting portion 13 is further connected to the container 20.
By press-fitting into the inner peripheral edge portion 22 of the tip, another seal portion D in a substantially line contact state is formed in this portion.
When the circular flexible portion 11 is pressed, the circular press-fitting portion is accompanied with it.
Since 13 bulges outward, the contact pressure of this seal part D is not
It always grows. The circular flexible portion 11 and therefore the two seal portions C and D can surely prevent moisture from invading along the front end surface 21 of the container 20 from the direction b. The presence of the seal portion D by the circular press-fitting portion 13 is extremely important, because moisture is hardly adsorbed by the desiccant 3 with respect to moisture intrusion from the b direction. Further, since the projection 16 provided on the outer peripheral end of the circular flexible portion 11 contacts the inner surface of the cap main body 1 at least after pressing, sliding of the circular rib portion 15 on the outer peripheral side is restricted. Therefore, the supporting reaction force of the circular flexible portion 11 becomes high, and the reaction force increases the pressure contact force to the seal portion D. ─────────────────────────────────────────────────── ───
