Reference numeral 1 denotes a circular annular part 2 at the upper end, a shallow saucer-shaped circular bottom part 3 at the lower end, and the annular part 2 and the bottom part 3. Left and right columnar portions 4 that are connected to each other, and the inner surface of each columnar portion 4 has an equally spaced pitch in the vertical direction within a length range of about several centimeters in the vicinity of the center in the vertical direction. Further, the concavo-convex portion 5 is a skeleton member formed over the entire length in the width direction of the columnar portion. The skeleton member 1 is made of a synthetic resin material such as polypropylene, polyethylene, nylon, or polyester, and can be molded to a desired hardness by changing the thickness depending on the material used.

  6 is a flexible blank sheet attached to the skeleton member 1 so as to wrap around the skeleton member 1, and the blank sheet 6 is entirely made of a synthetic resin material similar to the material constituting the skeleton member 1. Alternatively, at least the inner surface may be made of the same type of synthetic resin material as the material constituting the skeleton member 1. This blank sheet 6 is connected by a circular sheet portion 6a that matches the shape of the back surface of the bottom portion 3 of the skeleton member 1 and narrow connection portions 6b and 6b on both sides of the sheet portion 6a. 2 and a sheet portion 6c, 6c close to a fan shape for concealing an opening surrounded by the bottom portion 3, the left and right columnar portions 4. The sheet portion 6a of the blank sheet 6 is joined to the back surface of the bottom portion 3 of the skeleton member 1 by heat welding, and the periphery of the sheet portions 6c and 6c, specifically the lower end is the outer surface of the rising portion 3a around the bottom portion 3 Further, the upper end is joined to the outer surface of the lower end of the periphery of the annular portion 2 and both sides are joined to the outer surfaces of the left and right columnar portions 4 by thermal welding, respectively, so that the periphery of the skeleton member 1 is wrapped. The opening surrounded by the columnar part 4 is hidden, and the cup-shaped container 7 is formed.

  By the way, in molding the cup-shaped container 7, a mold composed of a core and a cavity is used, and the core is fitted into the cavity while the sheet portion 6a of the blank sheet 6 is applied to the tip of the core and sucked. By injecting resin between the cavities, a cup-shaped container 7 in which the blank sheet 6 is thermally welded to the skeleton member 1 as described above is formed.

The cup-shaped container 7 stores beverage liquid such as juice or confectionery, and in such a state, the lid body is detachably joined to the upper end of the annular portion 2 of the skeleton member 1 with a finger.
Further, depending on the contents stored in the cup-shaped container 7, the cup-shaped container 7 can be provided with a barrier property.
