Definitions

  • the present invention relates to a chain of laterally interconnected bags comprising in combination: a plurality of bags formed of a plastic film, each having releasably interlocking rib and groove elements on confronting inner faces at the top thereof, each closed by a side seam at each side edge and positioned in side-by-side relationship to form a chain; and a strip of material integral with the material of the bags and detachably connected to the top of each bag alone a line of weakened resistance, especially formed by a plurality of perforations extending parallel to said chain for manual separation from said chain for separating individual bags therefrom.
  • Such chain is known from GB-A 2 109 771.
  • the bags which are involved are thin plastic film bags which have sides and a bottom edge and at the upper end have a reclosable zipper lock structure.
  • the zipper lock structure constitutes a set of interlocking rib and groove profiles.
  • the lock structure is closable and the bag is closed by applying and opposed closure pressure progressively along the length of the profile elements.
  • the lock structure and the bag is opened when the profiles are separated by either drawing them apart, such as by pulling flaps which extend above the profiles laterally or by longitudinal movement of one profile relative to another in such a manner that the profiles snap apart.
  • Reclosable bags of the type described are disclosed, for example, in US-A 28 969 RE, US-A 3 338 284 and US-A 29 208 RE.
  • Bags of the above type are typically made by the plastic being continuously extruded from a circular die to form an endless profile tube.
  • the bags can be made from a folded flat film with interlocking profiles adjacent either end with said profiles either attached integrally or separately attached.
  • the profiles can be formed integrally with the material of the bag or may be on strips which are then secured to the bag material.
  • the mating interlocking profiles are formed on the inner surface of the tube. The profiles are joined when the plastic has cooled sufficiently to eliminate distortion of the plastic. Subsequently, individual bags are formed by cross-seals at spaced intervals to form a seam at each of the side edges of each of the bags with the bags being simultaneously cut from the tube at said seam.
  • the bags are manufactured and are stored to be sold and shipped to the user who opens, fills and recloses the individual bags.
  • These bags may be stacked in boxes, but in one preferred form, the bags are interconnected to each other in strip or chain form with individual bags torn off of the supply strip.
  • This form of chain of bags is advantageously utilized in automatic filling and handling machines, and one arrangement for utilizing such a chain of bags is disclosed in US-A 4 490 959, where automatic machinery has been devised for feeding, opening, and re- closing the reclosable bags.
  • Such mechanism utilizes a series of interconnected bags drawing them along a travel path through work stations of the machine.
  • the individual bags are removed from the supply chain by being 'forcibly torn from the chain. Whether torn from the chain or otherwise disconnected, a relatively high speed production operation can occur by pulling the chain of bags from a supply source, either a roll or a box and having individual bags disconnected from the chain as they are handled by the machine.
  • a significant feature of providing such a chain of bags is that the formation of the chain or interconnection of the bag be done simply without interfering with the manufacturing operation and without adversely affecting the strength and appearance of the bag. Also, whether the bags are forcibly torn from each other, or the interconnecting means is broken or separated by other arrangements as will be described herein, the bags must be separated without damage to them, and also separated rapidly and easily without slowing the high speed operation of the filling and closing machine.
  • an object of the invention to provide an improved bag chain structure wherein the ease of separation of the bags can be controlled by an improved structure for the attachment of bags to each other to form a continuous chain wherein the structure serves to accurately align the adjacent bags to each other maintaining the interlocking rib and groove elements and the top and bottom edges in alignment.
  • An advantage of this form of the invention is to manufacture bags sequentially and provide a removable strip along both edges so that the strip can be separated to sequentially release the bags such as by tearing the strip from the edge.
  • FIG. 1 The only Figure illustrates a chain of bags with the bags preferably formed of a thin polyethylene material and attached to each other in a side-by-side relationship. Bags are shown at 10 and 11 having heat sealed side seams 14 and 15, and a cross section of the bag 9 is shown to illustrate sidewalls 12 and 13. The bottom is closed along a heat sealed seam 16.
  • rib and groove elements 17 and 18 Adjacent the top of the bag on confronting faces are pressure interlocking rib and groove elements 17 and 18.
  • the rib and groove elements are separable in using the bag by pulling apart flanges 23 and 24 at the top of the bag.
  • a strip 19 which is a continuation of the bag walls 12 and 13 below the bottom seam 16, extends along the bottom of the bags and is perforated below said seam by perforations 20.
  • the side seams 14 and 15 extend slightly beyond sealed seam 16 into into the perforations 20 so that when the strip 19 is torn along said perforations, the bags in the chain become separated.
  • a similar strip 21 which is a continuation of flange flap, 24 and extends along the top of the bags and is perforated by perforations 22.
  • the individual connected bags after their rib and groove elements have been pulled apart are filled and then the rib and groove elements are pressed together.
  • the filled bags are then separated from the chain by tearing the strips 19 and 21 from the chain which release the individual bags from the chain. Until the strips are torn off, the bags are interconnected in a chain. It is also possible that the user may wish to fill the individual bags after they have been separated from the chain. In that case the bags will be released by tearing the strips off the chain and each bag will be released to be taken individually and filled when the strips are progressively torn from the chain.
  • the strips 19 and 21 are preferably of material integral with the bag material.
