Abstract: Non-crosslinked polyolefin films or doped crosslinked polyolefin films (i.e., crosslinked polyolefin films that include a tear-alignment additive) may be used to shrink-wrap packages to create a wrapped package that is protected from tampering and damage but is also easy to open with little effort required by the customer. There is no need for perforations, and the films are quiet when torn, folded, cut, etc. Tear initiating cuts may be formed in the film. A tab may be placed over the film, and when the tab is pulled it applies enough force to start a pair of straight tears. The tears may be parallel or perpendicular to each other. The tears propagate in non-crosslinked polyolefin easily in the machine direction of the film as the tab continues to be pulled. In a doped crosslinked polyolefin, the tears propagate in the machine direction or perpendicular to the machine direction of the film.

Abstract: A closure package includes a closure cap and a liner having a pull-tab. The liner is configured for use with a container having a finish or lip portion having a sealing surface at an uppermost portion thereof. The closure cap has a top wall portion and a depending skirt portion depending from the top wall portion. The top wall portion and sealing liner is adapted to coact with the container sealing surface to form a seal therebetween. The liner of the subject invention is for use with a closure package and is disposed in cap, positioned intermediate the top wall portion and the container sealing surface when the cap is positioned on the container. The liner is circular and has a central portion and a tab portion integral with the central portion, extending outwardly from a periphery thereof. The tab is folded on or above a tangent to the periphery of the liner, over the central portion into a folded position, and defines a hinge region at the juncture of the tab and outside the tangential line to the liner circumference. The tab is knurled to provide an improved, secure grip.

Abstract: A food container formed from plastic, can be loaded with food and then closed by a clerk, and thereafter cannot be opened without tearing apart first sides (24, 26) of the base (12) and lid (16). The container is formed by a single sheet of plastic that forms a base and lid with second sides (20, 22) that are latched together and with adjacent first sides that are joined by a joint line (30) in the plastic that is creased and that has slits (40). At the joint line, the lid has a projecting lid tab (32) and the base has a projecting base tab (36). A person grasps both tabs, and lifts only the lid tab to tear apart the first sides of the base and lid along the joint line (30). Thereafter, the lid can be easily closed and reopened on the base.

Abstract: A tab is provided to facilitate opening of a can end. The tab has a nose portion located at a first end of the tab and a lift portion located at a second end of the tab opposite the nose portion. A rivet receiving portion is located proximate to the nose portion, and includes a rivet hole. A flange extends rearwardly from the lift portion of the tab to define a gap. The gap provides increased space between the underside of the flange and the exterior of the container end, thereby facilitating opening of the container end.

Abstract: An upper panel has a shearing line including a shear-start portion, linear portions extending from opposite ends of the shear-start portion in an equal length, and an arced portion connecting leading edges of the linear portion. The upper panel also has foldable lines and ribs on the upper panel, each of the foldable lines being located at a position inner to and in parallel to each of the linear portions, and each of the ribs extending in parallel with each of the foldable lines. A pull tab has a fixing portion fixed to a portion of the upper panel inner to the shear-start portion. The pull tab has a pressing portion extending out the shearing line so as to press a portion of the upper panel located outside of the shear-start portion when a raising portion of the pull tab is raised. When the pull tab is raised for opening operation, each of the linear portions of a part detached from the upper panel has a sheared edge curled toward the inside of a container, providing safety.

Abstract: A container for packaging a particulate product under pressure or vacuum conditions with an easy opening closure structure which allows venting prior to uncovering of the product opening. In one form, an easy peel flexible lid covers a shelf area and a product opening in the top of the can. Peeling back the lid first uncovers the vent opening, permitting the flow of gases but preventing the flow of particulate product, and then uncovers the product opening. Alternatively, the closure structure may be formed by multiple layers of a flexible material, the lower layer of which has the vent opening which is uncovered by peeling back the top layer, after which the product opening is uncovered.

Abstract: A press-on closure 10 for a tubular container 12. The closure includes a molded plastic frame 14 having a ledge 28 on which an end panel 16 is seated and to which the end panel is peelably secured. The end panel has a free outer peripheral edge unbonded to the frame. The resultant closed container is subject to retorting with the result that heretofore the end panel could axially outwardly deform and possibly initiate internal peeling. To prevent this peeling, the frame is provided with a thin flexible integral flange 36 forming a continuation of the ledge on which the end panel is seated. The end panel is also peelably bonded to the flange and the flange deforms or deflects with the end panel. The frame has a press fit onto the container, which is preferably in the form of a metal can, which at the end thereof to be closed by the closure is provided with a radially outwardly directed curl 48. The curl terminates in a raw edge 54 and is so shaped that when it is seated within a groove in the underside of the frame, the raw edge is embedded in a skirt portion of the frame to permanently and sealingly lock the curl within the frame.

Abstract: A frangible seal breaking and aperture resealing device for a beverage container which utilizes a handle being pivotally mounted on the top of the beverage container. The handle is movable from a stowage position to a frangible seal breaking position and then to an aperture resealing position. There is incorporated on the top a camming protuberance which has the function of locating the handle in an inclined or canted position so as to facilitate its movement to frangibly separate a break-away tab incorporated within the top of the beverage container. The camming protuberance also exerts a biasing force tending to maintain the handle in the resealing position.
