  • Patent number: 10183766
    Abstract: A food package for sliced food products to be maintained with a fluffed appearance, the package including a rigid base member forming a compartment for receiving the food product and a rigid lid sealed to the compartment. Advantageously, the base member includes a bottom wall and side wall portions that are configured to engage the food product to hold the slices in a fluffed arrangement thereof. Preferably, one or more tapered side wall portions hold the food product upwardly toward the lid and inwardly toward a center of the package. In preferred embodiments, the base member and lid provide a rigid-rigid construction of the food package. In preferred embodiments, the food package is also configured to stand-up in a vertical display orientation and does not require the food product be contained within a sealed pouch within the compartment.

  • Patent number: 8939695
    Abstract: A metal end is applied and sealed to a plastic or paper/plastic composite container body by a crimp-seaming or double-seaming operation. The metal end has an outer curl joined to a compound-angle chuck wall that extends down from the curl. The chuck wall has an upper part that is substantially linear and at an angle ?1 with respect to an axis of the end, and a lower part that is substantially linear and at a larger angle ?2 with respect to the axis. The compound-angle chuck wall allows a substantial diametral clearance between a lower end of the lower part of the chuck wall and the inner surface of the container body, while there is substantially zero clearance, or preferably an interference fit, between the upper part of the chuck wall and the inner surface of the container body. Accordingly, the chuck wall guides the end into concentric alignment with the container body during application.

    Abstract: The aim of the invention is to produce can bodies (24?) comprising a can shell (24) and a closing element (31b, 32, 31a) that is fixed to one face of the can shell (24). Said aim is achieved by producing a tube (11) from a metal strip (1), optionally from directly adjacent sections (112), by means of a shaping step, at least one optional cutting step, and a continuous welding step, sections of said tube (11) being used as closed convex surfaces for cans. The sections are shaped by a shell-shaping device in such a way that can shells (24) are provided into which a closing element (31b, 32, 31a), especially a can bottom (31b), can be inserted. The longitudinal seam (11a, 124) can be produced inexpensively and at great precision essentially as a continuous seam in the welding step by means of simple installations.

The circumferential chuckwall extends downwardly from the curl to the transition wall. The transition wall connects the chuck wall with the substantially planar peripheral edge of the central panel. The transition wall has a folded portion extending outwardly relative to the longitudinal axis.

  • Patent number: 6129494
    Abstract: Sealant is applied onto or into a folded-seam closure of a metal can. Instead of introducing sealant into the U-shaped lid flange and drying, according to the invention the compound or sealant is applied to the base flange, the base of the metal can being dipped into a current of fluid sealant or at least brought into contact with it at the surface. This substantially improves the precision of dosing and the exact amount of applied sealant.

  • Patent number: 5957647
    Abstract: The invention is directed to a method of manufacturing a double seam joining a can end (2) to a can body (1) which includes a sidewall (13) terminating in an outwardly directed flange (16) having a flange angle (.alpha.) within the range of 0 to -45.degree.. During the support of the can end (2) upon the flange (16) of the can body, seeming rolls (37, 38) form a double seam while an axial load of 600N or less is applied to force the can end and the can body one against the other.

  • Patent number: 5947673
    Abstract: An improvement in the shape of a fold in a tin can allows the use of sheet metal of lower gauge than that currently used. This is achieved with a fold geometry on a tin can which is closed off with a double fold, such as for a drink or food tin; by providing a continuous or stepped contour on the fold side; and by insuring that the lid hook is clearly in area-contact (positive fit) on its outer side with the free end of the body hook in its lower third. The invention may be applied to standard-gauge as well as thinner-gauge sheet metal, and generally results in a better seal.

  • Patent number: 5676512
    Abstract: An aerosol container cover having a central opening for a nozzle and an outer edge adapted for sealing attachment to the open end of an aerosol container body. The aerosol container cover being of a relatively thin walled metal and having a wall thickness in the range of 0.005 to 0.013 inch (0.127 to 0.330 mm) if the metal is steel, and being 0.005 to 0.018 inch (0.127 to 0.457 mm) in wall thickness if the metal is aluminum. The cover is thinner walled than would prevent distortion or eversion of the cover at government mandated minimum pressure levels in the aerosol container. The cover is of a generally convex dome shape as it extends from its outer edge to the central opening, and being free of any countersunk recess in the vicinity of its outer edge. In a method of making the aerosol container cover, the cover is attached to a container body by conventional seaming processing.

  • Patent number: 5499438
    Abstract: A pallet container (1) for liquids has a replaceable inner container (2) made of sheet metal, an outer jacket (6) made of latticework, as well as a pallet (9)in the form of a bottom tray (10), which receives the bottom (16) of the inner container. The inner container (2)is made of sheet steel, preferably constructed as a double-walled structure, and is welded together from a jacket (11), a bottom part (12) and a cover (13). For the production of the inner container, a rectangular sheet-metal blank is bent to form a pipe element, whose mating edges are welded lengthwise. The pipe element is stretched to form a jacket of rectangular cross section. Then, a peripheral bead with a V-shaped cross section in each of the two end areas of the jacket is formed at a distance from its edges, which then are cut. Then, the deep-drawn, tray-shaped bottom part with a rounded edge is superposed or joined exactly to the outer sides of one bead of the jacket and the bottom part is attached to the jacket.

  • Patent number: 5320468
    Abstract: The present invention refers to a can seaming process, through which it is possible to produce cans by seaming (fixing) tops and ends to bodies of cans by micro-seaming process. This process provides the use of materials with 0.16 mm thickness or less, with a high hardness DR8 or DR9 for making tops and ends. As a result of the micro-seaming process a significant reduction of dimensions has been obtained on the cover and body hooks and in the length of the seam, without changing volumetric capacity of the can.

  • Patent number: 5277357
    Abstract: A process for making a metal wall enclosure of a package for housing an electronic element. An elongated strip, to be formed as the metal sidewall of the enclosure, and a bottom plate, for closing an open end of the metal sidewall, are formed from a sheet of metal stock. At least one aperture is selectively provided in at least one of the bottom plate and the planar metal strip. The strip is prepared for folding, such as by transverse grooves formed in the strip along predetermined fold lines corresponding to corners of the metal sidewall, to facilitate folding of the strip into the desired configuration of the metal sidewall and with the opposite ends of the strip, as folded to form the metal sidewall, in abutting relationship.
