  • Patent number: 6996949
    Abstract: The packaging container includes a container body formed from a packaging material, and a cap unit attached to a top wall of the container body. The cap unit includes a lip, a pull tab which covers a discharge opening and an inner tape which covers the discharge opening portion from a reverse side of the packaging material. Since the cap is attached to the packaging material in advance of forming the container, positioning of the container body is not required for cap attachment.

  • Patent number: 6217500
    Abstract: A twist-tie cluster is described that includes a plurality of twist ties, each having a wire retained within a strip of material, wherein a cut is made in each of said wires between said first end and said second end, and where an uncut portion of the material connects the twist ties. A connecting means connects first segments of the twist ties together. A twist-tie dispenser is also described including a back wall and a cam member rotatable between a first position and a second position, where the second position traps the twist ties between the back wall and the cam member. A method of dispensing twist-ties is described including trapping a group of twist-ties between a cam member and a back wall.

  • Patent number: 5961434
    Abstract: A cluster of twist-ties is formed by arranging twist-ties generally parallel to one another and interconnecting the twist-ties at a common end. The twist-ties are severed proximate the common end so that a person can pull on an opposite, free end of any twist-tie to remove it from the cluster.

  • Patent number: 5547451
    Abstract: An easy-open container has a spirally-wound paperboard bodywall layer, interior barrier liner layer and outer label layer forming an easy-open seam extending spirally between the ends of the container. A feature is provided for directionally-orienting tearing of the label layer to remove either the entire label layer or just that portion of the label layer which is in bridging relationship to the easy-open spiral seam to allow opening of the container along the spiral seam.

  • Patent number: 5251809
    Abstract: The invention provides spirally wound easy-open containers which comprise a spirally wound body wall having overlapped edges and which have capabilities and benefits associated with conventional butt jointed containers. The overlapped edges of the body wall define an easy-open seam extending helically between the ends of the container. A temporary adhesive between the overlapped edges of the body wall releasably adheres the overlapped edges of the body wall together and allows for opening of the container along the helical, easy-open seam. The easy-open containers provided according to the invention can be readily manufactured with only slight modifications to the conventional manufacturing process. Nevertheless, the easy-open containers of the invention can provide for material savings in container label construction and can allow for vacuum packaging of food products such as dough.

  • Patent number: 5238306
    Abstract: A closure system for a film wall package includes profile strips having a reclosable seal of the interlocking type, flange elements and, adjacent the reclosable seal, an adhered strip of peelable material. The peelable material and the profile strip may be co-extruded. With packaging film attached to the profile strips, typically to the flange elements, the resulting product may be used in a horizontal form, fill and seal operation, at which time the reclosable elements are mated and a peel seal is formed. The peel seal may be disposed on either side of the reclosable seal with respect to the interior of the package. The benefits of both peel seals and reclosable seals may be obtained by using optimum materials for those elements while, at the same time, allowing the use of a different material for the walls of the package.

  • Patent number: 5232431
    Abstract: A dispenser system for dispensing a plurality of twist-ties like closure devices 52 arranged in side-by-side alignment and attached at a second end 61 in sheets 50. The attached second ends 61 are crimped about a rod 51 which is inserted in slots 107 defined in side edges 102 of dispenser 100. A plurality of sheets 50 may selectively be inserted in dispenser 100. The dispenser also includes a cover 103 and a tie alignment block 106. The individual ties have a series of transverse perforations 53, 54 through the wire 55 and proximate the wire 55 to ensure ease of removal and ensure reference of the rotating devices 242 utilized in fabricating the tie 52. Fabrication of the sheets 50 includes taking a stock of uncut twist-tie material 21, advancing it into a cutting station 203 utilizing rotating knives 242, and guillotine-style knives 245, 246. The material 20 is then advanced to a crimping station 205.

  • Patent number: 4782646
    Abstract: In the manufacture of aseptic packing containers from weblike laminate material, the material usually is brought into contact with a liquid sterilizing agent which, after a certain treatment period, is removed again. In order to avoid any accumulation of residues of sterilizing agent behind lugs, opening strips or the like a method and an arrangement for finishing an opening arrangement (2) on a packing container (1) are proposed, according to which an external gripping element (3) is placed over the opening region (4) only after the packing container (1) has been filled with the desired contents and has been closed. This is achieved with the help of a sealing unit (9) with a vacuum device (10) and a gas-permeable striplike gripping element (3).
