Abstract (en)
[origin: WO9423917A1] The tool has a female mould (14), a male mould (54) and a one-piece diaphragm (20) arranged between them which is complementary to the outside of the container and has a radial swelling (24) with two opposite side pieces (26) for each handle. On the inside, the side pieces (26) each have a projection (28) to form a grip aperture in the handle. An adjusting device (40) presses the side pieces (26) together before the introduction of the material to be pressed into the tool and during the pressing process in such a way that the projections (28) adjoin. As a result, only a thin flash remains in the grip aperture which can easily be smoothed off. To remove the pressed handled container, the adjusting device (40) moves the side pieces (26) apart until the space between the projections (28) is wider than the handle.
