The apparatus comprises a carrier (9) having an opening for supporting sleeve (1) in each of two (raised and lowered) positions, a welding ring (10) around the opening for melting the adhesive, and a plunger (11) for successively pressing the two blanks (27, 3) into sleeve (1), while at the same time shaping them and forming a folded rim or flange on each.

Abstract: A packing container of the non-returnable type is frequently manufactured from laminated material which comprises a central carrier layer of paper with thermoplastic layers applied to both sides. As an opening arrangement, a pre-punched pouring opening is used which is covered on the one hand by a tear-off cover strip located outside the packing container and, on the other hand, by an inner protective strip. A method for sealing an emptying opening in accordance with the invention ensures that a part of the inner protective strip corresponding to the shape and size of the pouring opening accompanies the cover strip since the strips are heat-sealed to each other at the same time as they are pressed against each other by means of pressure fluid. An arrangement for carrying out the method comprises a heating device with a heatable zone and an outlet for pressure fluid.

Abstract: A composite can construction wherein the body wall, adjacent either one or both cap receiving ends thereof, is inwardly compressed to reduce the outside diameter of the tubular body while maintaining the inside diameter. The compression, reducing the thickness of the body wall, also densifies the material thereof without effecting the interior of the container or the structural integrity thereof. The compressed area extends along the length of the container body a distance sufficient to project substantially beyond the bead formed as a metal end cap is seamed to the body, thus providing a recess for facilitating accommodating of the driving wheel of a conventional can opener. The formed bead, utilizing the pre-compressed body portion and the denser material thereof, is relatively narrower and stiffer than the bead conventionally obtained upon the sealing of a metal end cap to a composite tubular body.

Abstract: A container having a generally rectangular rim surrounding its opening is closed by a foil membrane that extends over the rim and is sealed to the rim by inductively heating it. The membrane does not correspond in configuration to the rim, but instead its side and end margins curve away from the sides and ends, respectively, of the container rim, so that the peripheral margin of the membrane is located closer to the container rim at the corners of the rim than at the sides or ends of the rim. The foil of the membrane is coated with a resin bonding material, and when the membrane is placed in a rapidly oscillating magnetic field, its foil is inductively heated throughout the entire area that overlies the rim, thereby rendering the bonding material plastic and establishing a uniform bond between the rim and membrane.

Abstract: A composite container body having metal ends secured thereto by means of conventional crimping, and intended for opening by use of any of the various types of toothed driving wheel can openers presently in service. In a particularly preferred embodiment this is accomplished by compressing and densifying the end portion or portions of the composite container body a sufficient distance along its length to eliminate or at least minimize any interference between the toothed driving wheel of the can opener and the exterior of the container body. A weakening score line is preferably provided around the periphery of the metal end to be opened to even further reduce the resistance to cutting encountered by the cutter element as the toothed driving wheel advances said cutter element about the periphery of the container.
