Definitions

  • This invention relates to tamper evident bags, and in particular, to bags which are intended for the transportation of cash or other valuables.
  • a bag having a first pocket for containing cash, such as coins, which can be closed with a security seal, and also including a second sealable pocket which may be opened separately, for containing banknotes or identifying documents.
  • the present invention provides a tamper evident bag including a first pocket of plastics material with an opening having a closure flap adapted to form a tamper evident seal and a second pocket, whose opening is adjacent to that of the first pocket so as to be closed by the same flap, characterised in that the second pocket has an external wall which is perforated so as to allow separate access to the second pocket by tearing the perforations after the bag has been sealed.
  • the first pocket is made by folding over one end of an elongate strip of plastics material such as translucent or transparent polyethylene, and sealing the opposite side edges to form a pocket, and then heat sealing further layers or strips of polyethylene material, onto the bag in a known fashion to form the required further pocket and closure flap.
  • plastics material such as translucent or transparent polyethylene
  • the tamper evident seal comprises a seal embodying layers of adhesive and patterns of lines which are broken up when the seal is opened, as described for example in WO 91/04199, or WO 93/16933.
  • the second, or outer pocket is made of two layers of opaque material, so that the contents of the pocket cannot be seen through the material of the bag, and in a preferred embodiment, each of these layers is made from co-extruded polyethylene material, which facilitates the production of an opaque or coloured material. Alternatively all the layers may be translucent or transparent.
  • the main body of the bag is made from an elongate strip of plastics material, such as polyethylene 2, which is folded over at one end 4, so that the overlapping section, 6, extends about half way along the total length of the bag. This forms the inner end of the first pocket.
  • the remaining part of the first pocket is formed by a second layer, 8, of opaque co-extruded polyethylene material, which is heat sealed, as illustrated at 10, to the short edge of the main part 2 of the bag, i.e. the end opposite the folded end 4.
  • the co-extrusion process facilitates the production of opaque and/or coloured layers, if required.
  • the other end of sheet 8 is heat sealed, as illustrated at 12, to the opposite free end of the overlapped portion 6 of the main body, and a transverse slit 14 in the sheet 8 forms the opening to the main pocket of the bag.
  • a second pocket is formed by superimposing a further short length 16 of co-extruded opaque material, whose lefthand edge, as seen in the drawings, is also heat sealed along the line 12, whilst its righthand edge, 18, is left free, forming an opening to the second pocket which is adjacent to the opening 14 of the main pocket.
  • a strip 20 including a tamper indicating seal is heat sealed by one edge, at 22, so as to form a flap overlying both openings, as shown in Figure 2.
  • All the layers of the bag are then heat sealed along the opposite side edges 24 and 26, and as will be seen from the drawings, this creates a completely enclosed region at the righthand end, bounded by the side edges and the heat seal lines 10 and 22, which can be used to form a handle for the bag by means of an aperture 28 (not shown in Fig. 2).
  • This area may also be colour-coded by virtue of the co-extruded material 8.
  • the edges of the aperture 28 are also heat sealed, and consequently, since the end portion consists of two superimposed layers of material, and is heat sealed along all its free edges, it provides a strongly reinforced region for the bag handle.
  • the tamper evident closure 20 forms a seal across the openings of both pockets of the bag, when it is closed.
  • a line of perforations 30 is provided, at the lefthand edge of the pocket as seen in the drawings. Because the edge 18 is positioned to the left of the slit 14, the main pocket remains sealed even though the second pocket is open.
