Definitions

  • the present invention relates to box-like containers of sheet material according to the preamble to Claim 1.
  • Containers of this type are used widely, for example, in the food industry and, in particular, for the packaging of confectionery products such as pastries, chocolate bars, etc.
  • a container of this type is produced from a profiled, flat, intermediate element of sheet material such as card which is then folded and closed in a generally tube-like configuration.
  • This forms, for example, a generally flat, parallelepipedal box with two larger side faces and two smaller side faces facing one another in pairs and defining two end openings closed by end tabs.
  • Each tab usually comprises a proximal portion which extends from one of the side faces (typically one of the larger side faces) of the box and is intended to cover a respective end opening of the box, as well as a distal portion which can be inserted at least partially inside the wrapper defined by the container when the proximal portion of the tab is folded to the position in which it covers the respective end opening of the container.
  • the user often does not remove the bar from the container completely in order to eat it but simply removes it from the container far enough to expose the part to be eaten, then slides the uneaten portion back into the container.
  • the container which was originally formed to hold the whole product is, in the end, too large to accommodate only a portion of the product. This may create difficulties for the user in withdrawing the remaining portion of the product and removing it from the container.
  • the object of the present invention is to provide a container of sheet material of the type specified above in which the aforementioned problems and disadvantages are avoided.
  • this object is achieved by virtue of a box-like container of sheet material having the specific characteristics recited in Claim 1.
  • Advantageous developments of the invention form the subject of dependent Claims 2 to 11.
  • a box-like container of sheet material such as, in a typical embodiment, thin card, is generally indicated 1.
  • the container 1 is in the form of a flat, parallelepipedal box in which it is possible to distinguish two larger side faces 2, two smaller side faces 3 and two closure tabs 4 which close the ends of the tubular wrapper defined by the paired side faces 2 and 3 of the container 1.
  • the criteria for the production of a container 1 of the type specified above may be considered widely known and in current use in the paper industry. This applies in particular with regard to the specific method of producing the wrapper 1 from an intermediate element constituted by a single piece of sheet material such as card in which the various faces 2, 3, as well as the end tabs 4 are formed by successive punching, cutting and pre-folding operations to form the lines which connect adjacent faces and are intended to define the corners of the container 1.
  • the method of folding the intermediate element along the fold lines, and closing it like a tube, as well as the provision of gluing regions and the subsequent building-up of the container 1 in its final shape are also known in the art.
  • each tab 4 has a proximal portion 5, so to speak, extending from one of the larger faces 2 of the box, from a fold line 5a.
  • the portion 5 can therefore be folded perpendicular to the corresponding larger face 2 of the box, so as to close completely one of the end openings of the tubular wrapper defined by the larger faces 2 and 3.
  • Each tab 4 then comprises a distal portion 6 which extends from the respective proximal portion 5 from a fold line 6a and extends a certain distance inside the container when the proximal portion 5 is closing the respective end opening of the box.
  • the product inside the container 1 can be removed from the container by turning one of the tabs 4 over to the open position so as to render one of the end openings of the container 1 accessible.
  • This can easily be achieved by gripping the tab 4 which is to be turned over, preferably with a gripping action exerted on the distal portion 6.
  • This latter operation is usually facilitated by the presence of notches 7 (see Figure 1 in particular) in the corresponding larger face 2 of the wrapper.
  • the important characteristic of the invention is the provision, within the container 1, of a modular structure which enables its size to be reduced gradually by the removal of one or more portions or pieces of the container in succession, at the same time ensuring that the opening created as a result of the removal of a portion can be closed selectively by tab-like portions substantially comparable to the tabs 4 provided in the original container.
  • this object is achieved by the provision of one or more tear lines 10 in the body of the container 1 (see Figures 1 and 2 in particular in this connection).
  • two of these lines 10 are provided and are constituted by lines of perforations in the card forming the wrapper 1 which define, within the container 1, two end portions S1 and S2 which can be separated from the rest of the container 1. This is achieved as a result of the pulling or tearing of the sheet material constituting the container along the tear lines 10.
  • the two tear lines 10 divide the container 1 into a central portion and two end portions, in a generally symmetrical arrangement.
  • tear lines 10' are also provided in association with the tear lines 10 already described and, in the embodiment illustrated herein, are also constituted by lines of perforations of the card constituting the container 1.
  • the lines 10' which, together with the respective lines 10, extend generally circumferentially relative to the container 1, define in the container 1 (and, in the embodiment illustrated herein, within one of the principal faces 2) respective tab portions, generally indicated 4' in the drawings, each of which also comprises a proximal portion 5' and a distal portion 6', defined by respective fold lines 5a', 6a'.
  • the method of use of the container according to the invention provides, so to speak, for the gradual reduction of the length of the container in the sequence shown schematically in Figures 3 to 6.
  • the container 1, as shown in Figures 1 and 2 initially contains, for example, a bar of chocolate, the size of which corresponds to the size of the container 1.
  • the user has eaten a portion of the chocolate bar equal, for example, to one quarter of the length of the bar, that is, a portion corresponding approximately to the length of the end portion defined by one of the tear lines 10.
  • the user can tear the wrapper 1 along the tear line 10 facing the end of the container which was previously opened so as to separate the end portion, generally indicated S1 in Figure 3, from the container.
  • the container has the shape shown in Figure 4.
  • the user now has a container 1 which, whilst being “shorter” than the original, retains the characteristic that it can be closed at the two ends.
  • the same sequence to shorten the container can be repeated with the removal of another portion such as the portion indicated S2 in Figure 5.
  • the removal of the portion S2 brings about, on the one hand, the formation of a new end mouth or opening of the container and, on the other hand, as a result of the tearing along the corresponding shaped line 10', the formation of a new tab 4' which can be used to close the end opening.
