Definitions

  • This invention relates to tamper proof containers and particularly to envelope-like bags used for the transmission of documents, money and other valuables.
  • Such containers are required to hold the contents securely, and preferably, to render obvious any attempt at unauthorised access to the contents.
  • Bags of this type for use in carrying cash may be formed from an elongate sheet of material, which is folded over along a line offset from the centre, so as to form a U-shape in cross-section with one arm of the U longer than the other, the overlapping side edges then being welded together so that the long arm of the U provides a projecting flap which can be folded over the open mouth of the bag, to form a closure.
  • a bag of this type is referred to herein below as a "bag of the type herein described”.
  • the present invention seeks to provide a security bag with improved protection against unauthorised tampering.
  • a bag of the type herein described including a membrane of material having one edge welded to the inner surface of the flap, so that the free portion of the membrane extends into the open mouth of the bag, the flap being coated with a security adhesive so that it can be folded down to adhere onto the exposed surface of the membrane, and also onto the outer face of the bag.
  • the security container of the invention may be made from flexible plastic, such as polyethylene film, paper, foil or laminate of such materials which can be formed into bags, pouches, sachets, sacks or the like.
  • the flap is also transversely perforated in the adhesive area, so that any attempt at peeling open the closure will cause severance of the perforations.
  • a transverse stripe of solvent sensitive ink may be applied to the front face of the bag, so that any application of solvent to the closure adhesive will be rendered obvious.
  • the bag is made from an elongate sheet of plastics film material which is folded over at 6, to form a front wall 8 and a rear wall 10, the rear wall extending beyond the free edge of the front wall so as to form a closure flap 1.
  • the side edges 12 of the bag are heat sealed to form an open bag-like structure having a mouth 14 for the insertion of the contents.
  • the inner surface of the flap 1 is coated with a security adhesive, and also carries parallel lines of perforations 5 so that the flap will be permanently damaged if any attempt is made to peel the adhesive once the bag has been closed.
  • a membrane 2 also of plastics film material, is heat welded to the flap 1 by its upper edge 16, so as to form a captive flap which extends into the mouth 14 of the bag, so that the upper portion is visible as indicated at 2 in Figure 1, whilst the lower portion 3 is concealed below the upper edge of the outer face 8 of the bag.
  • the flap 1 is folded over as shown in Figure 3, and when pressure is subsequently applied to the outer surface of flap 1, it adheres to the upper portion of captive flap 2, as well as to the outer surface 4 of the front wall 8 of the bag, as shown in Figure 4, in an area which is coated with a stripe of solvent sensitive ink.
  • the adhesive on the flap 1 attaches to the surface of the captive flap 2, it is also more difficult to remove the contents by shaking them to the top of the container in order to obtain access through the side edges, since the contents will then be retained behind the captive flap.
  • the latter is treated by a known corona discharge process, which improves the affinity of the surface for the adhesive.
