<p>A cap of sealing preservation container comprises a central plug 3 arranged inside a cap body 2 that is attachable to a mouth 5a of a sealing preservation container 5. The cap body 2 forms a retention section 2c projecting toward an opening 2b. The central plug 3 forms internally a receiving space 3c that receives the retention section 2c to enter through an opening. The central plug 3 is inserted in such a way as being opposing the retention section 2c and vertically movable in unison with the retention section 2c, while rotating force of the retention section 2c being not applied to the central plug 3. As such, the operation of bottle opening is made easy and the container is re-usable and maintains sealing performance.</p> |
