摘要:
The invention relates to a method for producing a container which is made of a plastic material and comprises the edge clamping of a flat and flexible part (5) forming a curved surface on the internal face of a hollow body (1). The inventive method consists in bringing the edge of the part (5) into contact with the internal face of the hollow body, in applying a pushing or tensile force on the part in a direction perpendicular to the surface thereof in such a way that radial forces are induced into the part, thereby bringing the edge of the part (5) together with the internal face of the hollow body.

The invention relates to an elastic substantially tubular package (1) for a semi-liquid or pasty extractable by a finger pressure product comprising a skirt (2), a head (3) and optionally a cap (4), wherein said skirt (2) is formed from a wound foil and is provided with a longitudinal weld seam (6) formed by the overlapping of the edges thereof and the head (3) is fixed to the circumference of the skirt end (7) and forms an oval cross-section at the level of the skirt (2) fixing area. The inventive package (1) is characterised in that the end of the longitudinal weld seam (6) contacting the head is located in or near an area where the radius of curvature of the oval cross-section is minimal.

A sealing device for sealing non-circular, in particular polygonal, for example tetragonal, hexagonal, octagonal or elliptical, container openings comprises one or a plurality of induction loops (11, 38, 41) for sealing purposes. Containers (2) comprise joined-on closure devices (3) with sealing discs (15) joined onto a sealing edge (14) of the container opening. The induction loops (11, 38, 41) are adapted to the shape of the sealing edge (14) and the spacing between the induction loop (11, 38, 41) and sealing edge (14) is constantly adjustable and selectable.

A cap heat-sealing apparatus for paper containers comprises a vertically movable head, a fixed pressing member provided on the bottom surface of the head, a pair of divided movable pressing members arranged around the fixed pressing member and connected to the head so as to be horizontally movable toward or away from the fixed pressing member, and a heating high-frequency coil attached to the head and surrounding the fixed pressing member. The fixed pressing member has an outer perophery shaped to position along the inner surfaces of heat-sealing container opening edge fitting portions of inverted V-shaped cross section formed at the outer periphery of a square paper cap, which has an aluminum foil layer. The movable pressing members have an inner periphery shaped to position along the outer surfaces of the fitting portions. The high-frequency coil is spaced apart from the fixed pressing member by a clearance for the fitting portions to enter.
