<P>PROBLEM TO BE SOLVED: To provide a delamination container easily manufactured and assembled, improved in sealing performance without the age-based degradation of sealing performance and preventing a change in the external shape of the container by leading in air between an outer layer and an inner layer and preventing the content of the inner layer from being exposed to air while allowing a cap to be provided with virgin seal with a large opening. <P>SOLUTION: A side part of an opening cylindrical portion 120 of the delamination container 100 is provided with at least one through hole 121, and an inner plug 150 having a valve mechanism separating from and contacting with the opening cylindrical portion 120 is inserted into a skirt wall portion 140 of the cap 130. The inner plug 150 includes a holding outer frame 151 of hollow cylinder shape, a central valve element 152 permitting only the unidirectional flow of the content, and an air valve element 153 permitting only the unidirectional flow of air. <P>COPYRIGHT: (C)2013,JPO&INPIT |
