Filed:

Jan 18, 2005

Appl. No.:

10/586723

Inventors:

William M. Heyn - New Canaan CT, US

International Classification:

B21D 51/30
B21D 51/44

US Classification:

413 4, 413 8, 413 12

Abstract:

End panel () has its periphery () affixed to a flange portion () of container ring member () disposed in a planar position, and the flange portion () is then displaced from the plane for forming an angle (A) therewith. The method results in placing the interface between the end panel () and the flange portion () in sheer, rather than in peel, during retorting or unintentional impact loading.

William Heyn - New Canaan CT, US

International Classification:

B65D 41/00
B65D 43/14
B65D 43/02

US Classification:

220359100, 229125350, 229123100, 220359400

Abstract:

A tubular container is provided with an angled sealing surface extending outwardly and downwardly around the upper periphery of the container. A flexible end panel, such as plastic film, metal foil, or thin plastic, or coated paper stock is heat or adhesively sealed to the angled surface of the container. This combination of container and end panel is particularly effective for food products and the like that are subjected to heat treatment, such as in a retort, following a filling operation of the container and sealing of the end panel thereto. The angled sealing surface retains the end panel in shear, rather than in peel, as the end panel bulges upwardly because of increased internal pressure. The integrity of the seal, at the interface of the container and the overlying end panel, is greatly enhanced.

Inventors:

William M. Heyn - New Canaan CT, US

International Classification:

B65D 41/16

US Classification:

215317

Abstract:

An overcap () for a container () closed by a flexible end panel () is snapped or twisted or threaded onto the container to lie closely adjacent to the flexible end panel for reducing the possibility of the end panel being separated from the container incident to retorting or impact loading. The underside of the overcap may be provided with one or more depending annular rings or leg members () to be placed closely adjacent to or in contact with the flexible end panel to preclude undesirable movement thereof.

Donald J. Roth - Westport CT

Assignee:

Polystar Packaging, Inc. - Norwalk CT

International Classification:

B29C 5300

US Classification:

264153

Abstract:

Tooling for forming an article which includes an injection molded peripheral frame defining an opening closed by a panel insert. The panel insert is struck from sheet material and together with an associated punch or carrier cooperates with a split mold to completely define the cavity for injection molding of the article. Inasmuch as the panel insert is heat bondable to the injection molded frame and forms a portion of the walls of the cavity, it is automatically bonded to the injection molded frame. The panel insert may be peelable from the frame and include a pull tab for effecting the same. The pull tab may be formed by the same punch which cuts out the panel insert, or the pull tab may be separately formed from sheet material adjacent an intended position of a panel insert and folded into overlying relation to the intended position of the panel insert and staked to the sheet material, after which the panel insert is cut from the sheet material by a punch. The pull tab is initially connected to the sheet material along an elongated fold line, after which not all of the pull tab connected to the sheet material is removed by the punch so as to define a centrally located pull tab which is aligned with the projecting part of the punch to effect a completely sealed mold cavity utilizing the panel insert with a previously formed and folded over pull tab staked thereto.

Assignee:

Polystar Packaging, Incorporated - Norwalk CT

International Classification:

B29C 4514

US Classification:

264154

Abstract:

Closures for containers, such as cans and the like, wherein the closure is comprised of an end panel and a frame member which, preferably, are attached together during an insert-injection molding operation used for forming the frame member. Depending upon the respective materials, the attachment therebetween may comprise heat-bonding or adhesives and the like. The various end panels have a displaceable panel portion for providing an opening in the closure to provide access to the product(s) within the container. The various panel portions are defined by weakening lines, perforations or cut lines in the end panel and molded runners for "repairing" and/or sealing weakened or lanced portions of the end panels. The molded runners provide beam strength for protecting against excessive bulging during autoclave or other sterilization processes and against buckling during vacuum processing.

US Classification:

220269

Abstract:

Closures for containers, such as cans and the like, wherein the closure is comprised of an end panel and a frame member which, preferrably, are attached together during an insert-injection molding operation used for forming the frame member. Depending upon the respective materials, the attachment therebetween may comprise heat-bonding or adhesives, and the like. The various end panels have a displaceable panel portion for providing an opening in the closure to provide access to the product(s) within the container.

Inventors:

William M. Heyn - New Canaan CT

Assignee:

The Continental Group, Inc. - New York NY

International Classification:

B65D 1734
B65D 5116

US Classification:

220271

Abstract:

A lightweight container of thin metal such as aluminum which is subject to collapse when load is exerted thereagainst wherein the closure and container are made to minimize the application of such load, the container having a pouring neck and the closure having a panel with a groove into which the neck is telescoped and adhesively bonded thereto, the closure being openable by exerting tensile forces thereon for breeching a selected area of the securement of the closure panel to the neck and then fracturing a push-in section of the panel and whereupon minimal forces are required to open the container without imposing undesirable loads thereagainst. The closure also is tamperproof and vents prior to opening.
