Cup shaped container
The present invention provides a cup shaped container that can be squashed to be compact by hand when disposing after use. The cup shaped container includes a skeletal member made from synthetic resin material and having a ring-like part at the upper end, a shallow saucer-like bottom part at the lower end and columnar parts for connecting the ring-like part and the bottom part, and a blank sheet attached to the skeletal member to wrap the periphery between the ring-like part at the upper end and the bottom part at the lower end of the skeletal member. Each columnar part has, on its inner surface, an indented part formed in the neighborhood of the middle of the columnar part, and protrusions and depressions of the indented part are formed at an equally spaced pitch in an up and down direction of the columnar part.
1. A cup shaped container used for liquid comprising:
a skeletal member made from a synthetic resin and including a ring-like part at an upper end, a shallow saucer-like bottom part at a lower end, and columnar parts for connecting the ring-like part and the bottom part, each columnar part having an indented part on an inner surface in a neighborhood of a central part thereof for a full width of the columnar part, the indented part having protrusions and depressions being formed equally spaced at a few millimeter pitch in an up and down direction of the columnar part; and
a blank sheet made from watertight material and attached to the skeletal member so as to cover an opening defined by the ring-like part, the bottom part and the columnar parts of the skeletal member, wherein when disposing the cup shaped container, the columnar parts are bent inward at a middle due to the presence of the indented part by applying a force in a direction of compressing the cup shaped container from above and below, whereby the cup shaped container is squashed to be compact.
