Definitions

  • This invention relates to a bag closure, and in particular to a bipartite bag closure, the parts of which each comprise a strip with a handle or hanger member, each strip being attached to an edge of a bag opening, and the strips having cooperating means, distributed along their lengths, for closing the bag opening by holding the strips together, and a hinge element being provided at opposite ends of the bag closure.
  • the handle strip is made of singular construction with two score lines spaced apart a distance corresponding to the length of the bag opening, with the sum of the lengths projecting on opposite sides beyond the score lines also corresponding to the length of the bag opening.
  • These projecting strip portions can be folded over towards each other about the score lines, and when the free ends are interconnected there is formed a bag closure with two strips fixedly interconnected at their ends, but one of which carries a coupling member e.g. halfway along its length.
  • a bipartite bag closure which does admit of being optimally opened is proposed in French patent 2,088,777, in which the closure strips are interconnected at their ends by a hinge element comprising a pin and a sleeve rotatable about the pin.
  • a bipartite bag closure as defined in the opening paragraph of this specification is characterized in that each hinge element is a flexible lip formed on a strip end and adapted to be folded and to be secured to the juxtaposed end of the other strip.
  • the hinge element could be made as a loose element and be connected to both strip ends, but preferably the lip is formed as a prolongation of each strip end and carries a coupling member moiety at its free end, the other moiety of which is arranged on the corresponding end of the other strip.
  • a flexible prolongation lip may be provided at its free end with a press button moiety, the other moeity of which is arranged on the opposite strip end.
  • each lip connected to a strip end carries a press-button moiety, the other moiety of which is arranged on the side of the other strip end facing away from the strip end connected to the lip. Accordingly, in the coupled condition, the lip is folded over the strip end concerned, and when the two strips are pulled apart, the forces exerted on the hinge do not tend to open the press-button closure, but on the contrary force the one press-button moiety into the direction of the other press-button moiety, so that the terminal press buttons are effectively prevented from being opened.
  • each strip of the bag closure according to the invention may be provided on one end with a lip and at the other end with a press-button moiety, it is simpler, from the point of view of manufacturing technique, to provide one strip with a prolongation lip on both ends, and the other strip just with press-button moieties at both ends.
  • the prolongation lips may be made thin compared to the strip material, so that they are very flexible. It is thus ensured that the strips can be pressed flatly against each other by the cooperating closure members virtually throughout their entire length. This is in particular of importance in case the package is a display package, and a packed article may be on display for a long period of time. With the bag closure according to the invention it is ensured that during such presentation in the shop the packed article cannot be soiled by the ingress of dust and the like.
  • a plastics bag 1 comprising two sheets 5 and 6 interconnected by side edges 2 and 3 and a bottom edge 4, has an opening 7 defined by edges 8 and 9, with which the bag is connected, by heat sealing or otherwise, two strips 10 and 11 forming part of a bipartite bag closure. At least one of the strips 10, 11 is equipped with a handle or hanger member 12. Snap closures, such as press buttons, are spaced uniformly over the length of the strips, of which Fig. 1 shows spigot moieties 13 on the side of strip 11, and of which the corresponding socket moieties are provided in strip 12.
  • hinge elements in the form of relatively thin, flexible lips 14 are formed at the ends of strip 11 which lips have a spigot press-button moiety 15, and socket press-button moieties in the form of holes 16 are formed in the ends of strip 10.
  • another hole 17 may be provided in strip 11, which hole 17 can receive the head of press-button 15 which projects through hole 16 when the strip ends lie flat against each other.
  • Fig. 1 clearly shows that the bag can be optimally opened without there being a risk of snap closures 15, 16 becoming detached, and hence of bag edges 2 and 3 being torn.
  • lips 14 may be formed not both on one strip, but one on either, or alternatively loose hinge lips may be used, which are snap-fastened to both strips. It is also possible for press button 15 to engage with strips 10 from the inside.
