Japanese Patent JP2668300
Kind Code:
B2
Abstract:
PURPOSE: To provide a two-piece fitted cup-shape container made of thermo- contractive and thermo-plastic materials.
CONSTITUTION: A two-piece fitted cup-shaped container C comprises a continuous sidewall B having an open upper end and including a recessed bottom. The sidewall B is made of a thermo-contractive and thermo-plastic single sheet having similar both ends. Both ends of the sheet are joined with each other along a liquid-tight seam. The sidewall B extends downward from a point neighboring the upper opening of the container C to a point neighboring the bottom, and then is folded upward at a lower edge 11 of the sidewall to form a doubled wall portion 10, 12, and then extends inward. Thus, the sidewall B forms the doubled wall portion 10, 12 and the annular portion 13, which radially extends inward and underlies a separate bottom member 14 sealingly joined to the radially extending portion from the bottom edge of the sidewall.
