<P>PROBLEM TO BE SOLVED: To provide such an airtight lid structure of a container that a small take-out hole is formed in an airtight seal of the container, and a necessary amount of contents is taken out through the small hole by shaking the container so as to prevent moisture from entering the container. <P>SOLUTION: A lid structure is composed of an airtight attachable/detachable outer lid formed on an opening of the container, and the airtight seal which is stuck on the peripheral edge of the opening and is broken upon unsealing the outer lid. The airtight seal is provided with the take-out hole which is then sealed with a peelable take-out hole seal to form the airtight lid structure of the container. Frequently taking the contents out of the container 1 with a spoon or the like results in the ingress of moisture into the container 1. According to the airtight lid structure of the container, the small take-out hole 9 is formed in advance in the airtight seal 8, and the airtight take-out hole seal 10 is joined so as to be peelable to the airtight seal 8 which is provided with an elastic hinge flap lid 13. This remarkably reduces the amount of moisture that enters the container 1 through the opening 2 upon opening the container 1 first and opening it repeatedly afterward. The airtight lid structure is thus composed of the airtight attachable/detachable outer lid 4 formed at the opening 2 of the container 1, and the airtight seal 8 which is stuck on the peripheral edge 3 of the opening 2 and is broken upon unsealing the outer lid 4. This lid structure solves the problem that the moisture enters the container 1 through the wide open opening 2 to damage the contents at moment when the airtight seal 8 is broken to unseal the outer lid 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
