Definitions

  • the present invention relates to a film of plastic material forming an elongated strip for packaging coins which are arranged in axial alignment and face-to-face contact, by wrapping the strip about the body of coins with marginal edge portions projecting from each end of the body of coins.
  • US-A-3,491,507 describes the use of heat-shrinkable material for packing coins, said material being wrapped about a solid cylindrical body of coins which are arranged in axial alignment and face-to-face contact.
  • the heat-shrinkable material is heated over the entire length of the body of coins so as to shrink into firm engagement with the cylindrical surface of the body of coins.
  • the heat-shrinkable material tends to break at the edges of the ends of the coin body and, moreover, it is difficult to apply a satisfactory print on the package e.g. in order to identify the denomination of the coins in the package or the bank or other monetary institution that has produced the package, because the print is distorted by the shrinking of the heat-shrinkable material.
  • the package obtained is hard and rigid and is difficult to open.
  • the object of the invention is to provide a film of the kind referred to above which substantially facilitates the packaging and at the same time overcomes the disadvantages mentioned above.
  • a solid cylindrical body 10 of coins arranged in axial alignment and face-to-face contact is enclosed to form a package by an elongated strip 11 of a film of plastic material being wrapped about the coin body.
  • the film can consist of any of the conventional materials used for packaging films such as polyethylene or polypropylene.
  • the wrapping is effected by the coin body being held between supports 12 and being rotated in the direction indicated by the arrow 13 while an elongated strip of said material and having a proper length is being wrapped about the coin body.
  • the coin body should have such a width that marginal edge portions 14 thereof project from the edge of the coin body 10.
  • regions of the elongated strip at the ends of the coin body, including the projecting marginal edge portions 14, are heated to a proper temperature in order to effect contraction of the film at said end portions.
  • heating means 15 limiting the heating to the end portions, and such heating means can comprise electrical radiation heaters or nozzles for expelling hot air towards the end portions of the coin body.
  • the coin body enclosed by the elongated strip wrapped about said body is being rotated during said heating.
  • Fig. 3 according to which the marginal edge portions 14 by heating of the film have contracted over the end surfaces of the body of coins.
  • a print on the film, if any, will not be distorted when practising the method as described above, because that part of the package which is located between the restricted end portions which are heated locally, will not be heated at all and therefore will not contract onto the body of coins.
  • the coin package thus obtained can be opened easily, the package at the same time being sufficiently safe so as to withstand the rough handling to which the package may be exposed during transport in a bag or a box.
  • the package can be more easily opened by providing in the elongated strip of plastic film a central longitudinal perforation 16. Due to this perforation it will be easy to break the package centrally thereof, the enclosure being split at the perforation. Since the plastic film has not contracted onto the major part of the length of the coin body, the coins can be easily discharged from the two halves of the enclosure.
  • the invention provides a film of plastic material in the form of an elongated strip constructed in a special way as shown in Fig. 4.
  • the elongated strip shown in Fig. 4 can consist of any of the conventional plastic materials used for packaging purposes such as polyethylene or polypropylene.
  • the marginal edge portions 17 thereof which in a typical embodiment can have a width of 5 to 7 mm are made more heat-absorbing than the intermediate portion 18, a heat-absorbing material being entrained into or applied to the marginal edge portions 17.
  • a heat-absorbing material can comprise e.g. a metal or metal-oxide pigment.
  • the marginal edge portions 17 can be made opaque e.g. by applying a dark (black) colour to said portions.
  • the pigment can be applied e.g. by printing such pigment on the elongated strip.
  • the intermediate portion 18 can be provided with the proper print supplying desired information.
  • the width of the marginal edge portions 17 is adjusted to the length of the body of coins such that these portions, when the elongated strip is arranged centrally on the coin body and is wrapped about said body, cover the uttermost end portions of the coin body and project from the ends thereof. Due to the fact that the marginal edge portions 17 are more heat-absorbing than the intermediate portion 18, said marginal edge portions will be heated more rapidly when the end portions of the film are heated locally, such that the film will contract locally more rapidly at the end portions while the intermediate portion 18 will be substantially unaffected by the heating. The marginal edge portions 17 will contract about the ends of the body of coins and will bend over the end surfaces of the coin body e.g. 3 to 5 mm as shown in Fig. 3. As soon as this has taken place the heat radiation can be discontinued with the intermediate portion 18 intact.
  • the film of the elongated strip is transparent in order to eliminate the possibility of cheating by including in the package iron washers or an iron rod as a substitute for coins.
  • the transparent package makes possible to check the contents of the package by ocular inspection of the contents of the package from the outside thereof without the necessity of breaking the package.
  • the film can be laminated in the manner shown in Fig. 5 an inner layer 19 being provided with a print indicated diagrammatically by lines 20, at one side thereof, and this side of the inner layer is covered by an outer layer 21 which accordingly must be transparent so as to allow reading of the printed information through said layer.
  • the inner layer 19 preferably is transparent for the reasons mentioned above, but is not necessarily of this character.
  • the laminated film will be wrapped about the coin body with the layer 21 facing outwards, said layer protecting the print such that the print will not be damaged or erased.
  • Fig. 6 The embodiment shown in Fig. 6 has been developed from that shown in Fig. 5.
  • the two films forming the inner and outer layers 19 and 21, are put together while prestretching the film 19 such that the laminated film tends to curve as shown in Fig. 6.
  • the elongated strip comprising such laminated film will curve about the body of coins when it is to be wrapped about said body such that the wrapping operation will be facilitated.
