  • Patent number: 4762430
    Abstract: Draw tape bags for carrying trash have a draw tape with ribs extending across the width of the tape, each rib having a thickness greater than the thickness of the tape. The ribs prevent roping of the draw tape handle when a loaded bag is lifted. Roping is prevented because the packing of the ribs is not uniform, thereby creating free space between the ribs. Triangular and cylindrical elements are embedded in the tape to form the ribs.

  • Patent number: 4738545
    Abstract: A combination mat and carry bag unit includes a sheet of pliable material defining a mat of size to accommodate a person thereon for use as an exercise mat, beach mat or the like. The sheet has a drawstring casing extending about its periphery. The casing has two openings therein on opposite sides of the mat and a drawstring is received in the drawstring casing and is of size to extend continuously about the periphery of the sheet when it defines a mat. The drawstring is slidably received in the drawstring casing so that when portions of the drawstring are pulled out of the drawstring casing through the two openings, the periphery of the sheet forms gathers adjacent the casing to permit the periphery to reduce in size whereby the unit forms a carrying bag. Those portions of the drawstring which are pulled out of the casing are secured together adjacent the openings to form a handle for the carrying bag.

  • Patent number: 4646470
    Abstract: A fast fit liner for an earth ball of the type surrounding nursery plants and trees for transportation is formed from a square piece of cloth material which is folded at midpoints along each side thereof to form interiorly extending pleats, with the seams of the pleats being sewn. The seams divide the cloth into four sections which are drawn around the earth ball. The top free corners of each section can be folded over to receive a rope or other type of drawstring to pull the corners tight around the trunk of the plant or tree. The cloth can be folded and sewn in a number of different configurations to vary the shape of the liner to meet different requirements.

  • Patent number: 4628536
    Abstract: Draw tape bags have a high molecular weight, high density polyethylene draw tape which is intermittently stretched so that the tape has central portions of relatively narrow and thin oriented polyethylene and end portions which are relatively wide and thick. The end portions are heat sealed to the sides of the bag panels to secure them. The stretching makes the tape cost more economical and improves the break characteristics while the thick and wide end portions permit good heat sealing without weakening the draw tape. Also disclosed is a method of making such bags.

  • Patent number: 4558463
    Abstract: A draw tape trash bag made of linear low density polyethylene film has a tack seal between the folded over hem portion of the top of the bag and the adjacent panel. The tack seal extends in the direction of extrusion across the width of the bag below the draw tape. It includes a continuous line of heat fused polyethylene formed by applying heat, but limited pressure, in an amount just sufficient to weld the polyethylene.

  • Patent number: 4547237
    Abstract: A drawstring is mounted near the open mouth of a plastic bag by a pressure sensitive tape that freely laterally encloses the drawstring except for projecting free ends, the tape being formed or treated so as to be non-sticky with respect to the drawstring. A high speed production method of making the bags comprises the steps of laying a continuous length of drawstring material across a series of spaced bags, applying strips of pressure sensitive tape to each bag to freely laterally enclose the drawstring length there and severing the drawstring length between bags.

  • Patent number: 4493683
    Abstract: The present invention relates to a method of manufacturing bag-like packages of flexible material, in which each package is so arranged as to have a number of closure ribbons (38, 48). A blank belt (1) which is essentially double-folded in its longitudinal direction is divided into a number of consecutive, bag-like packaging blanks (7). A number of closure ribbons (38a, b and 48a, b) extend through similarly located channels in all the packaging blanks. The ribbons are shortened in their longitudinal direction, for instance by folding. The blank belt is moved over guide devices (6a, b) which open the packaging blanks at the same time as the distance between their openings (32", 32"') increases. This causes drawing out of sections of the closure ribbons (38, 48) from the channels in the adjacent packaging blanks. The drawn-out closure ribbons are attached to each other in pairs and are cut off at the areas of attachment so as to form endless closure ribbons for each and every one of the packaging blanks.

  • Patent number: RE32308
    Abstract: A flat reusable fill/discharge closure for the end wall (bottom or top) of a cloth bag for transporting bulk materials comprises a flexible tube folded back into itself to form a long inner fill/discharge tube and a short outer closure tube having a length less than the radius of an opening in the bag end wall; the tube fold is sewn into the periphery of the end wall opening of the bag with the closure and fill/discharge tubes projecting outwardly. A flat closure is effected by tying the fill/discharge tube closed, stuffing it into the bag interior, and then closing the closure tube by a drawstring mounted in its outer end.The questions raised in reexamination request No. 90/000,584, filed 07-06-84, have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e).
