Abstract

Provided is a container that allows a portion where detachment starts to be fixed at a specified position in a more reliable manner, thus allowing contents to be discharged in a direction expected by a user, allowing eventually reduction in the amount of contents to remain in the container in the end. The container includes a container body holding contents therein and a lid member, the container body and the lid member being sealed by an annular seal portion formed along a flanged face of the opening. There is provided a detaching seal portion which is detached in response to increase of pressure inside the container body associated with deformation of the container body. The detaching seal portion includes a reverse-oriented annular seal portion which occupies a part of a width of the flanged face and which projects toward a radial inner side of the opening.

First claim

1 . A container including a container body holding contents therein and a lid member for closing an opening of the container body, the container body and the lid member being sealed with each other by an annular seal portion formed along a flanged face of the opening;
wherein at a specified portion of the annular seal portion, there is provided a detaching seal portion which is detached in response to increase of pressure inside the container body associated with deformation of the container body; and the detaching seal portion includes a reverse-oriented annular seal portion which occupies a part of a width of the flanged face and which projects toward a radial inner side of the opening.

2 . The container according to claim 1 , wherein there is provided an auxiliary detaching seal portion which connects opposed ends on the radial outer side of the reverse-oriented annular seal portion.

3 . The container according to claim 1 or 2 , wherein:
an outflow channel for discharging the contents extends radially outwards from the detaching seal portion; and
at positions facing the outflow channel from the left and right sides thereof, there are provided non-detaching seal portions comprised of a plurality of annular seal portions extending along a circumferential direction.

4 . The container according to claim 3 , wherein:
the detaching seal portion and the non-detaching seal portion are connected to each other via a pair of left and right connecting annular seal portions; and between a portion of the pair of connecting annular seal portions and the outflow channel, there are provided a pair of auxiliary non-detaching seal portions facing each other across the outflow channel therebetween.

5 . The container according to claim 3 , wherein at a position of the flanged face of the container body corresponding to the outflow channel, there is formed an outflow groove sunk toward the bottom of the container body.

6 . The container according to claim 1 , wherein:
the annular seal portion is provided in the form of a groove sunk in the thickness direction of the flanged face by pressing the lid member against the flanged face via a seal bar having at its leading end an annular projection having a shape corresponding to the annular seal portion; and the reverse-oriented annular seal portion is provided as an uneven sealing force groove having a smaller curvature radius on its radial inner side than its radial outer side.
