Claims

[Scope of utility model registration request]

In an apparatus for manufacturing cup cases in which the bottom and side parts are simultaneously formed using a sheet of paper, the bottom part 12 of the trapezoidal recess 11 is approximately equal to the diameter of the bottom plate of the cup to be processed, and the inclined side wall 13 is Between the wedge-shaped tooth head surface 14 and the tooth bottom surface 15, there is provided a tooth end surface 16 for folding, which absorbs the difference between the bottom plate diameter of the cup and the outer diameter of the circular sheet (blank). The die 1 is provided with a tooth profile 17 having a truncated conical shape, and the inclined side wall 23 of the truncated conical block 21 has a tooth head surface 25, a tooth bottom surface 24, a tooth end surface 24, and a tooth end surface 26 that mesh with the tooth shape 17 of the die 1. A bottom plate 33 is inserted into a disc-shaped blank 3 using a punch 2 provided with a tooth profile 27.
A cup case manufacturing apparatus characterized in that a fold line 31 is provided to separate a side plate 35 and a fold line 32 for pleating is provided on the side plate 35.
