  • Patent number: 5746514
    Abstract: The laundry bag includes a body of openwork material defining a substantially spherical interior volume in at least one state and having an opening thereto. A closure is positioned at the opening to close the opening while maintaining the substantially spherical interior volume. The closure may include an additional body of openwork material extending from the opening and having an open end for inserting objects into the interior volume. Further, a laundry bag includes a body of openwork material defining an interior volume. The body of openwork material has an opening for insertion of objects into the interior volume and includes a closure portion of openwork material adjacent the opening such that when the closure portion is folded the interior volume is maintained. A method for using a laundry bag includes providing a laundry bag having a body of openwork material defining an interior volume and having an opening for insertion of objects into the interior volume.

  • Patent number: 5478153
    Abstract: The invention concerns a multilayer sack or bag with side folds which consists of several tubular webs with side folds inserted one into the other, in which arrangement at least one open end is closed by a bottom. To form a bottom that is comparatively less thick, the outer tubular web with side folds has a projecting flap that extends over its width. At least one inner tubular web with side folds is inserted into this tubular web with side folds in such a way that it terminates at the distal edge of the flap. The projecting strip extending parallel to the flap of the at least one inner tubular web with side folds is folded over onto the outer side of the outer tubular web with side folds. The tubular webs with side folds, inserted one into the other, are folded together round the outer edge of this folded over strip and are fixed in this position.

  • Patent number: 5425447
    Abstract: The bag is formed from two layers of a plastic having properties of mutual superficial adhesion. The layers are laid one on top of the other, and define between themselves at least two chambers each containing a different liquid. To simplify the operations of manufacturing and using the bag, without contaminating the liquids contained in the chambers, the chambers are separated from each other by a separating septum formed by a section of mutual adhesion of the two layers, in which the two layers are in intimate superficial contact. The adherent section is bounded by two lines where the layers are folded to define throttle lines which prevent the liquids from getting from the two chambers into the adherent section. To use the bag, the bag is simply unfolded and pressure is applied to the chambers, in such a way as to cause the layers to come apart in the adherent section and the liquids to mix.

  • Patent number: 5281027
    Abstract: A tubular bag blank has a plurality of outer contiguous non-heat sealable plies and an inner heat sealable plastic ply. All of the plies in the tubular blank are bonded together circumferentially around an open top end of the bag and are closed at the bottom end where only the non-heat sealable plies are bonded together. The inner heat sealable ply is freely folded and fully detachable in a non-adhesive manner at the bottom end of the bag. The inner plastic ply being heat sealable to closure at both bag ends. Upon heat sealing the bottom end, a plastic pouch is formed by the inner ply which may be heat sealed to closure at the open end when filled with a product or commodity and may be optionally severed thereat by compressive heat and pressure applied to the outer non-heat sealable plies. When fully packed, the outer paper plies may be stripped away leaving a sealed plastic pouch with the packaged contents therein ready for use by the purchaser.

  • Patent number: 5267795
    Abstract: A paper bag particularly adapted for the packaging of carryout food items such as hamburgers and chicken. The bag is of a unitary construction and includes two inwardly folded bellows panels on its sides, each bellows joining respective sides of the bag. A fold line is positioned below the top, free edges of the side walls. A pair of spaced cuts is located substantially midway of respective fold lines, each cut of each pair extending from above to below its respective fold line, the individual cuts being spaced from each other along the fold line. Respective areas of the front and rear bag walls above the fold line carry indicia, such as printed indicia, to indicate the bag contents. After folding the top of the bag about the fold lines and against either side walls, one or the other indicia is visible to indicate the bag contents. The bag top is inhibited from opening after such folding by distorting the paper between the cuts to effect a latching action.
