Cup shaped container

Abstract

The present invention aims to provide a cup shaped container that can be squashed by hand so as to become compact when disposing after use. For this purpose, 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 so as 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, a convexo-concave part formed at an equally spaced pitch at the central part in the up and down direction of the columnar part.

1 . A cup shaped container 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 a columnar part for connecting the ring-like part and the bottom part, the columnar part having a convexo-concave part on an inner surface thereof, the convexo-concave part having convexes and concaves being formed at an equally spaced pitch at a central part in an up and down direction of the columnar part; and    a blank sheet attached to the skeletal member so as to wrap a periphery of the skeletal member between the ring-like part at the upper end and the bottom part at the lower end.    
     
     
         2 . The cup shaped container as claimed in  claim 1 , wherein a joint surface of the blank sheet attaching to the skeletal member is made from a synthetic resin material of a same type as the skeletal member.  
     
     
         3 . A cup shaped container 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 a columnar part for connecting the ring-like part and the bottom part; and    a blank sheet attached to the skeletal member so as to wrap a periphery of the skeletal member between the ring-like part at the upper end and the bottom part at the lower end, wherein    the columnar part has a depression having a narrow width formed at a middle thereof as viewed from front.    
     
     
         4 . The cup shaped container as claimed in  claim 3 , wherein a joint surface of the blank sheet attaching to the skeletal member is made from a synthetic resin material of a same type as the skeletal member.
