  • Patent number: 5934547
    Abstract: A spiral wound type composite container of the type that is typically used for packaging refrigerated pressurized dough products includes, as is typical in such containers, an inner liner, a body wall that is wound about the inner layer so as to define a butt joint, and a label member that is wound about the body wall so as to bind the body wall against expansion as a result of forces that are created by the pressurized contents of the container. As is also typical in such containers, the label member has a tab defined at one portion thereof and a predetermined lead path forming the tab so that a consumer can grasp the tab and tear the label member along the lead path, thereby removing enough of the label member from the body wall so that forces of pressurization will cause the body wall to separate and open.

  • Patent number: 5918801
    Abstract: An improved display carton. The carton of the invention includes a front panel having lines of weakness extending from the top corners of the panel down to the scoreline defining the bottom of the front panel. Lines of weakness are also provided in one or more of the flaps defining the top of the carton. The flaps on the top of the carton do not completely close the carton so that a user may grasp the carton at the top and pull on the top panel to remove portions of the top and front panels and reveal the product within the case. A particularly advantageous feature of the invention,is the use of a cut in a scoreline to improve the compressive strength of the carton. The cut is made at the bottom of one or more columns of flutes at a point where the flute would otherwise bend due to the presence of a scoreline defining a fold. The cut causes a complete cut of the flute rather than folding; the complete cut results in an increase in compressive strength when compared to the folded flute.

  • Patent number: 5865367
    Abstract: A box having a container space for retaining box contents is provided. The box is constructed of a foldable sheet material. The box includes first and second side panels, first and second edge panels, and first and second end flaps. All flaps and panels are foldable about associated fold lines to effect a box having sides and seal ends which together define the container space. A removable strip portion is provided on either an end flap or an edge panel to provide access to the container space. The removable strip portion is defined by interior and exterior partial cuts scored into the foldable material, including a plurality of aligned interrupted exterior cuts that are disposed for an extent coincidentally with an associated fold line. The removable strip portion thus constructed helps ensure folding of the associated flap or panel about the intended fold line while maintaining the strength and integrity of the folded edge.

  • Patent number: 5704539
    Abstract: A reducible volume container includes a package wall made from a laminated material having interior surface and an exterior surface, with at least one tear strip formed in the package wall. At least one layer of the laminated material is a monoaxially oriented material disposed on an inner surface of the package wall. The tear strip is defined by a pair of generally parallel frangible tear lines. Each tear line includes a linear cut formed in the exterior of the package wall. The linear cut is disposed generally parallel to the axial orientation of the axially-oriented material, and each linear cut has a depth extending only partly through the thickness of the package wall.

  • Patent number: 5622309
    Abstract: The disadvantages of conventional carton for packaging cut sheets of paper such as the facts that fingers or finger nails are injured upon opening the carton, tearing requires a large force, the removal of the cut sheets is difficult, the beauty of surroundings is spoiled, movement of the carton is required, and industrial wastes are produced are solved by the present invention. A pair of opening face cut lines such as threaded lines, zipper and the like are formed on two selected faces of the rectangular parellelepiped carton, and a trigger cut line such as a threaded line, zipper and the like is formed on this one face or another face. The trigger cut line is connected to the opening face cut lines. The trigger cut line and the opening face cut lines are torn off after cutting and raising a part of the trigger cut line. The face having the opening face cut lines is used as an opened face.

  • Patent number: 5579943
    Abstract: A dispensing closure lid having a tear-away tab for use with a container. The tab itself is configured with an outwardly extending grasping member. The pull tab is defined by a distinct sequence of slits and perforations. The slits have a greater length than the perforations. The specific sequence of slits and perforations facilitates removal of the tab from the container mouth and provides for a clean separation of the tab from the land surface of the container and the remaining lid without tearing into the lid.

  • Patent number: 5505375
    Abstract: The outer surface of an article is covered with a wrapping film, and both ends of the wrapping film are lap-welded by heating, so that a body seal section is created. An unbonded part is formed on the periphery of the edge of an upper overlapping film of the wrapping film along the marginal line of the same. This unbonded part extends between the marginal line of the upper overlapping film and the edge of the body seal section. A slit is formed in the vicinity of the unbonded part at right angles to the marginal line of the upper overlapping film. A weakly bonded part, where the upper overlapping film and the lower overlapping film are weakly bonded to each other, is formed to be adjacent to the opposite side of the unbonded part of the body seal section relative to the slit, and extends from that side of the unbonded part to a predetermined length along a marginal line of the upper overlapping film.

  • Patent number: 5358176
    Abstract: A tearstrip opening for the closure flap of a paperboard container is formed by a single line of tear and an adjacent delamination area located within the closure flap. The tearstrip is applied to one or more of the closure flaps of the container as required. The tearstrip is removed by the combined action of separation of the paperboard along perforations which define the single line of tear and ply separation of the paperboard adjacent to a partial depth cut line of weakness spaced from the single line of tear. When removed, the tear strip releases the closure flap from a side wall of the container while leaving a portion of the closure flap still attached to the side wall.

The container blank includes a plurality of side panels foldably connected together in a longitudinal series, and a connecting flap foldably connected to a first end of the side panels. The side panels form a line of weakness extending substantially completely across each of the side panels, and the connecting flap forms a notch extending from the first end of the side panels. To form the container, the connecting flap is connected to the second end of the side panels, forming the side panels into a continuous side wall for the container; and as this is done, the notch in the connecting flap is positioned over the end portion of the line of weakness.

    Abstract: The invention relates to lids of easy-opening cans for perishable foodstuffs, and a method of obtaining them. These lids are composed of a metal foil and a plastics film, the metal foil having a mechanical non-traversing pre-incision corresponding to a tearing line and the thermo-shrinkable plastics film having a continuous depression situated opposite the mechanical pre-incision. The pre-incision and the depression, obtained by the action of heat, makes it possible to avoid the defects known as "feathering" and the plastics film is less expensive and more resistant to corrosion than is conventional lacquer.

One or more of the outer closure flaps include a tearback tab formed by weakened lines. A base portion of this tearback tab lies immediately over some of the articles in the case while an outer portion of this tearback tab overlies an inner closure flap. Tearing back the tearback tabs provide direct access to at least a portion of the upper parts of all articles within the case for purposes of marking same with tickets or the like. The tearback tabs are then unfolded back to their original flat state, and then tucked underneath an edge of the inner closure flap over which each previously overlied, thus reclosing the article case.
