Definitions

  • the present invention relates to packaging, and more particularly is directed to an improved package for packaging generally block-shaped product for example chocolate bars. Further, the present invention is directed to a method of packaging a block-shaped food products and to a use of a package.
  • a wrapper which is suitable for packaging food products is fabricated from a material which is substantially gas and moisture impervious, in order to maintain the article at a desired level of freshness.
  • the packaging is intended to provide customer information, for example the content of the packaging, its origin or other information. Additionally, the wrapping has to provide a pleasing appearance of the product.
  • Block-shaped products in particular food products being used as snacks, are often wrapped in a sheet of flat, foldable packing material.
  • this sheet is generally rectangular.
  • Such a sheet comprises an inner surface and an outer surface, whereby the inner surface is the surface directed to the food product to be packed.
  • an adhesive is applied to the inner surface of the sheet-shaped packing material to a frame-shaped portion surrounding the central portion onto which the block-shaped food product is laid.
  • an inner surface of the packing material which comprises a pressure sealable and re-sealable wax-like coating composition.
  • self-adhesive thermoplastic materials can be used which stick to each other upon application of moderate pressure.
  • the sheet material is folded around the block-shaped food product such that the block-shaped food product becomes wrapped and the inner surfaces of two opposite portions of the frame-shaped sealing portion contact.
  • the seals are formed around the sealing portion.
  • the sealing portion is frame-shaped and extends from the central body portion of the sheet material onto which the food product is laid to all outer edges of the sheet-shaped packing material, the seals are formed on the very outer edges of the package. Accordingly, it is difficult for a user to open the package without the aid of additional tools such as scissors or knives. Accordingly, such packages are often provided with incisions or perforations enhancing the convenient opening of the package. Such additional elements are provided at specified locations of the package.
  • US 3,291,377 discloses a conveniently openable package for enclosing a perishable comestible.
  • this package comprises a rectangular blank in the form of a generally rectangular sheet of a packing material.
  • This blank includes a central body portion onto which a food product to be packed is laid. Additionally, the blank comprises flaps on opposed longitudinal sides of the central portion.
  • the blank is folded around the product such that wings of the blank provided at opposite sides of the product abut one another in face to face relationship. Subsequently, the flaps which are attached to the extremities of the rings are folded inwardly of the wrapper along fold lines and are sealed thereto.
  • the package itself is sealed such that the folded flaps which form tabs remain freely accessible.
  • the package is closed along the abutting wings and front and end seal areas.
  • a package comprising all the technical features of the preamble of claim is known from US 5945145 A .
  • top, bottom, side, “front” and “rear” and the like denote the direction of the sheet-like packing material when this is conveyed within a packaging machine. Obviously, these directions are considered presently the most convenient ones for packaging a food product. However, the invention is not limited to these directions. On the contrary, these are intended to simplify the description of the present invention.
  • the invention is based on the idea that the opening of a package for a block-shaped food product is simplified by providing flap-shaped tabs along one of the sealings, namely a sealing which runs over the backside of a package. Accordingly, the package can be opened by simply applying a manual force and pulling the tabs or flap-shaped tabs away from each other such the crease formed by the seal running over the back surface of the package is opened.
  • any means which is per se well-known in the art for example applying adhesive or using a thermoplastic material on the inner surfaces of the sealing portion, may be employed.
  • the sheet material comprises two flap portions opposite each other. This means that one of the flap portions is adjacent one side portion of the sealing portion and the other flap portion is adjacent the other one of the side portions of the sealing portion, such that both flap portions are parallel to each other. This ensures an easy opening of the package as both flap portions can be gripped by a user with his fingers and pulled away from each other.
  • One of the flap portion is wider than other one of the flap portions. This ensures an easier gripping of the flap portions by a user who wishes to open the package.
  • these flap portions are provided along the edges of the sheet like packaging material which are parallel to the feeding direction in a packing machine. This enhances the workability when packing a block-shaped food product.
  • block-shaped food product a parallelepepid, a prism or similar shapes are addressed, as long as the food product is provided as one block to be packed.
  • the seal is formed by adhesive applied to the inner surfaces of the sheet in the sealing portion.
  • adhesive in particular a peelable adhesive
  • the sealant can be applied precisely only to those portions of the sheet-like material which are to form the seal.
  • a pattern may be embossed in these portions to enhance the closing strength of the package. This may be achieved by applying a pressure when producing the seal.
  • the package according to the present invention is particularly suited for use to wrap a product having a decorative upper face and a bottom face, in particular confectionary which has at least one decorative surface.
  • the food product is preferably placed on the sheet material such that upon closing the package the decorative upper face of the food product is directed towards the seal which is formed by the side portion of the sealing portion and which usually runs in a centre portion of the upper surface of the product. This is advantageous as a user immediately recognises the decorative pattern or the embossed information of the food product when opening the package.
  • such a food product is a chocolate bar.
  • the sealed side portions of the sealing portion together with the at least one adjacent flap portion are folded around a fold line formed at the border of the central body portion to one of the side portions. This may be done before or after sealing. This means that the package remains flat and, accordingly, very suited for transportation or storage.
  • Fig. 1 shows schematically a generally rectangular sheet of a flat, foldable packing material 10 which is conveyed in the direction of the arrow A in a packaging machine.
  • the sheet of foldable packing material comprises an inner surface (visible surface in Fig. 1 ) and an outer surface. Further, the sheet comprises a central body portion for enclosing the top, bottom, side, front rear surfaces of a block-shaped food product 12 which is illustrated in Fig. 1 as a chocolate bar. This central body portion is denoted in Fig. 1 with reference number 14.
  • a frame-shaped sealing portion 16 surrounds the central body portion.
  • the sealing portion 16 is coated with an adhesive on the inner surface of the sheet material 10 or is formed from a thermoplastic material, for example, so that the seals can be formed under temperatures and pressures which initiate a sticking of the coating to itself.
  • the sealing portion comprises a front portion 17, a rear portion 18 and two side portions 19.
  • the front portion 17 and the rear portion 18 of the sealing portion 16 are arranged such that they extend to the edge of the generally rectangular sheet of the flat foldable packing material 10.
  • the side portions 19 are located between the central body portion 14 and two flap portions 20, 21.
  • the flap portions 20, 21 extend the entire length of the side portions of the sealing portion and form the lateral outer end portion of the sheet of packing material.
  • the flap portion 20 is wider than the flap portion 21.
  • the foldable material can be formed from any suitable material, which is in particular suited for packing food products.
  • suitable material which is in particular suited for packing food products.
  • requirements regarding gas and moisture imperviousness, pleasing appearance, robustness, printability etc., can be taken into account.
  • the food product 12 for example a chocolate bar as shown in Fig. 1 , is placed on the folding material such that the food product 12 contacts the inner surface of the sheet.
  • the food product 12 is preferably placed onto the sheet such that its decorative surface, for example a surface comprising embossing, product information or grooves for breaking the food product, is directed upwards.
  • the food product 12 can be placed within the central body portion of the packing material according to the respective requirements.
  • the sealing line formed by the side portions 19 of the sealing portion is located in a central portion of the food product 12, the food product 12 has to be placed centrally and symmetrically within the central body portion and the sealing portion. It has to be noted that this does not necessarily mean that the food product 12 is placed symmetrically within the entire surface of the sheet of packing material. This is due to the effect that the flap portions 20, 21 have different widths.
  • the sheet material is folded around the food product 12 such that the inner surfaces (i.e. the visible surfaces in Fig. 1 ) of the side portions 19 of the sealing portion 16 contact.
  • the inner surfaces of the flap portion 20, 21 are also directed to each other.
  • a seal is formed, for example by applying pressure, only within the sealing portions such that the side portions 19 contact each other and such that the front portion 17 of the sealing portion 16 is folded back to itself as well as the rear portion 18 of the sealing portion is folded back to itself. Accordingly, the inner surface of the front portion 17 and the inner surface of the rear portion 18 contact themselves.
  • the overlapping portions 19 and 20, 21 of the packing material are folded back onto the central body portion, for example around the border of the central body portion 14 to the right-hand side portion 19 of the sealing portion or around the border of the central portion 14 to the left-hand side side portion 19 of the sealing portion. This means that the outer surfaces of the respective side portion 19 and the adjacent flap portion contact the outer surface of the central body portion.
  • a finished package is obtained which is shown in Figs. 2 and 3 . It is to be noted that the flap portions 20, 21 are only laid loosely above one another such that the inner surface as well as the outer surface thereof remains accessible.
  • a user wishing to open the package may grip one or preferably both of the flap portions 20, 21 and pull them away from each other such that the package is opened as shown in Figs. 2 and 3 .
  • the decorative surface of the food product 12 of the bottom surface of the food product 12 is directed to the consumer when opening the package as shown in Figs. 2 and 3 , wherein in Fig. 2 the decorative surface is directed to the consumer and in Fig. 3 the bottom surface.
  • the food product 12 is, for example, prism-shaped, it is of course possible that two decorative surfaces are directed upwards.
  • the food product 12 has to be placed upside down on the packing material with respect to the situation shown in Fig. 1 .
  • the present invention provides a package for packing generally block-shaped food products which is convenient to open and easy to manufacture. In particular, there are no additional folding steps required.
