<P>PROBLEM TO BE SOLVED: To provide a cup-shaped container that eliminates the need to check a mouth to be unsealed and that can be unsealed with a comparatively small force. <P>SOLUTION: The cup-shaped container includes a container body 1 of a cup-shaped sectional shape, which has a mouth that is open upward at the top, and a flange part 1c connected integrally with the outer peripheral edge of the mouth of the container body 1. At least, a film 2 is welded along the flange part 1c, thereby closing the mouth of the container body 1. The flange part 1c is provided with a separation tongue 3 to which part of at least the film 2 is welded and which connects to the flange part 1 so as to be separable from the flange part 1c. As a separation tongue 3, a pull-ring 5 is provided, which is lifted around a hinge h as a starting point, separates from the flange part 1c by applying a pulling force, and pulls off the film 2 on the entire region. <P>COPYRIGHT: (C)2010,JPO&INPIT |
