Definitions

  • the invention relates to a flow-pack packaging, especially a fiow-wrap packaging, and to a blank for producing a flow-wrap packaging in accordance with the preambles of patent claims 1 and 12.
  • Flow-pack packagings are packagings that are customarily used for packaging, for example, chocolate, confectionary bars or jelly sweets, but also for other products, such as, for example, household products or products of a technical nature.
  • Such packagings consist of a film, which may also be in the form of a laminate.
  • the film In the course of the production of a fiow-pack packaging, the film is usually unrolled from a supply reel and passes through a packaging station in which the film is wrapped around the goods being packaged and then closed on the longitudinal side by means of a fin-seal or lap-seal seam and usually on the transverse sides with a fin-seal seam.
  • a packaging station in which the film is wrapped around the goods being packaged and then closed on the longitudinal side by means of a fin-seal or lap-seal seam and usually on the transverse sides with a fin-seal seam.
  • Packagings of that kind are very versatile in use and economical to produce.
  • a disadvantage of such packagings lies in the fact that the packagings are usually not able to stand up, which means that any ability to stand up is governed exclusively by the shape of the packaged product, with the result that such a flow-pack packaging is not capable of standing in a stable position but falls over if the packaged product is not itself capable of standing up.
  • This example is mentioned here merely by way of example, but applies to all products that do not have their own clearly defined standing surface.
  • the invention is based on the problem of providing a flow-pack packaging, especially a flow-wrap packaging, and a blank for producing such a packaging, that avoids the above-mentioned disadvantages and that is simple and economical to produce using customary packaging machines.
  • a flow-pack packaging especially a flow-wrap packaging, having at least one longitudinal sealed seam in the form of a fin-seal or lap- seal and two transverse sealed seams, the packaging having at least two supporting overlaps which are substantially formed from a material forming the packaging and, in particular, forming the at least one longitudinal sealed seam and the transverse sealed seams, preferably a film material, for example a laminate material, and define a standing surface for the packaging.
  • a flow-pack packaging according to the invention has at least two supporting overlaps which are formed by an overlap of the material from which the flow-pack packaging has been formed, such supporting overlaps creating a thickening of the material forming the packaging in the region of the supporting overlap.
  • That thickening imparts higher strength and, in particular, rigidity to the material forming the packaging.
  • the supporting overlaps extend beyond the edge regions of the packaged goods as a continuation of a side face, wherein the at least two supporting overlaps run, at least over some portions, substantially in parallel, staggered in parallel or parallelogram-like and, with the respective edges of the supporting overlaps furthest away from the packaged goods, define a standing surface which encloses an angle of substantially 90° with respect to a side face of the flow- pack packaging.
  • An important aspect of the invention here is that at least two supporting overlaps are associated with one another and with a side of the flow-pack packaging and project beyond the boundary of the packaged goods associated with that side of the flow-pack packaging and, with the respective outer edges of a first supporting overlap and a second supporting overlap, which edges are in each case remote from the packaging, define a common standing surface.
  • that standing surface encloses an angle of substantially 90° with a side face of the flow-pack packaging, so that by means of that standing surface the flow- pack packaging stands vertically on a horizontal support.
  • the f!ow-pack packaging does not have a single side face or does not have a fiat side face
  • the lengths of the respective outer edges, remote from the packaging, of the first supporting overlap and the second supporting overlap are in any case such that a standing surface is defined which ensures a substantially upright standing position of the flow-pack packaging according to the invention.
  • the flow-pack packaging according to the invention can also have supporting overlaps of different lengths, that is to say that project by different amounts beyond the boundary of the packaged goods, so that by virtue of the supporting overlaps of different lengths an upright standing position of the flow-pack packaging can be ensured. That ability to stand up is achieved by the flow-pack packaging's standing on the outer edge, remote from the packaging, of the first supporting overlap on the one hand and on the outer edge, remote from the packaging, of the second supporting overlap on the other hand.
  • the supporting overlaps run substantially parallel to one another; also possible at this location, however, are supporting overlaps arranged at an angle to one another, which contact one another, for example, in the transverse sealed seam or are alternatively spaced apart from one another.
  • the length of the supporting overlaps it is possible for the length of the supporting overlaps to be selected so that the flow-pack packaging can be placed on a horizontal support specifically at an angle thereto, it being possible in the case of a substantiaily parallelepipedal flow-pack packaging for a side face of that packaging to be placed inclined at an angle in the range of from 30° to ⁇ 90°, preferably in the range of from 45° to ⁇ 90°, especially in the range of from 60° to ⁇ 90°.
  • the angle that can be achieved without the flow-pack packaging falling over as a result of too great an angle of inclination depends upon the nature of the packaged goods and upon the shape and centre of gravity thereof.
  • the supporting overlap consists of two or more layers of the packaging material.
  • This two-layered or multi-layered structure of the supporting overlaps can be formed, for example, by a fold of the material forming the packaging.
  • Such a fold can be realised, for example, directly in the packaging machine by means of suitable guidance of the film, for example by means of rollers.
  • a supporting overlap can also be formed by a fin-seal seam which, in accordance with a further embodiment of the invention, is, for example, preferably in the form of a longitudinal sealed seam.
  • Such an embodiment is especially advantageous because the longitudinal sealed seam, which is anyway necessary for closing the packaging, serves simultaneously as supporting overlap.
  • Such a variant can be used, for example, also in cases where a flow-pack packaging according to the invention is made not from a film in the form of a flow-wrap packaging but from two film webs which are guided towards one another and are sealed or adhesively bonded to one another.
  • a plurality of longitudinal sealed seams able to serve for sealing the packaging on the one hand and/or as supporting overlap on the other hand is also a possibility.
  • an overlap of portions of material forming the supporting overlap is fixed by means of adhesive, especially by means of cold adhesive.
  • adhesive especially by means of cold adhesive.
  • a fold forming a supporting overlap - this can also be a plurality of co-operating folds - is securely fixed and durable.
  • a reinforcing material such as, for example, a strip of metal or cardboard can be incorporated into the supporting seal, insofar as this is desirable.
  • Other materials having a reinforcing action are also possible at this location, such as, for example, a profiled film strip.
  • a special advantage of a supporting overlap formed according to the invention by means of a fold or a fin-seal seal fixed by means of cold adhesive lies, for example, in the fact that the supporting overlap can be formed continuously in a conventional packaging machine, because the supporting overlap can be created continuously, for example by folding or in the form of a fin-seal seam, which can then be fixed, likewise continuously, by means of cold adhesive, which can likewise take place continuously, for example using pressing rollers.
  • the production speed during the production of the flow-pack packaging is not to the slightest degree adversely affected by the production of the supporting overlaps, but can be maintained at maximum speed.
  • a further advantage of the use of cold adhesive lies in the fact that any kinds of materials can be adhesively bonded to one another, for example including those which cannot be heat-sealed, whether it be because the material to be bonded is itself not sealable or because the goods being packaged are heat-sensitive and so sealing is ruled out, as in the case, for example, of chocolate.
  • the fin-seal seam forming the supporting overlap is peelab!e and optionally reclosable, especially restickable.
  • Such an embodiment is advantageous especially when the fin-seal seam simultan- eously forms both the supporting overlap and the longitudinal sealed seam of the packaging according to the invention, since in that way the packaging is on the one hand able to stand up without requiring any additional material and, furthermore, is openable by means of the longitudinal sealed seam forming the supporting overlap, if the longitudinal sealed seam is peeled open for opening. If cold adhesive has been used for the production of the supporting overlap or the longitudinal sealed seam, that embodiment has the further advantage that the longitudinal sealed seam is restickable and the packaging is accordingly reclosable.
  • a further considerable advantage of a supporting overlap that simultaneously constitutes the longitudinal sealed seam of a packaging according to the invention lies, furthermore, in the fact that it is in this way possible to produce a packaging having two, or preferably four, side faces that are free of sealed seams, which can provide a visually attractive appearance and can be utilised, for example, as areas for advertising or other information.
  • An embodiment in which a supporting overlap simultaneously also constitutes a longitudinal sealed seam of the packaging can also be modified according to the invention to the effect that, instead of two supporting overlaps, four supporting overlaps are provided on a flow-pack packaging according to the invention, with in each case two supporting overlaps co-operating in pairs and, on respective side faces of the packaging, being arranged to project away from the packaging in opposite directions, so that the packaging has two standing surfaces, one of which is arranged at the bottom of the packaging when a packaging according to the invention is in a standing position.
  • the packaging according to the invention stands on a support by means of that standing surface.
  • the other, second standing surface projects upwards in the opposite direction from that of the first standing surface and can be used as an alternative standing surface to the first standing surface.
  • the two supporting overlaps associated with a side face can have open, that is to say non-folded, edges in the manner of fin-seal seals, so that the packaging is like a container having a lid formed by the side face, wherein the lid on the one hand is arranged on both sides and at an angle, especially a right-angle, to a transverse sealed seam and on the other hand in each case forms a supporting overlap and is also joined to the respective transverse sealed seams.
  • At least one fin-seal seam of a supporting overlap there is provided at least one corner region free of sealing medium or cold adhesive, which corner region is not sealed or adhesively bonded on the outside of the packaging and can be used as a grip tab for removing the side face formed as the lid of the packaging according to the invention, so that the remainder of the packaging constitutes a kind of "tray", that is to say a "box-like” packaging, which, however, as is preferred according to the invention, is made not from paper or cardboard or from a paper or cardboard laminate, but from a film material, especially a film laminate.
  • At least one fin-seal seam of a supporting overlap can have at least one region that is free of sealing medium or cold adhesive.
  • a transverse-sealed-seam- side end of a supporting overlap where here too a region, especially a corner region, that is free of sealing medium and/or of cold adhesive can be provided, the sealing- medium-free and/or cold-adhesive-free region optionally extending along a transverse- sealed-seam-side end of the packaging from one supporting overlap to an adjacent supporting overlap.
  • one side of the packaging can be partly or fully opened in a very simple way by removing, for example peeling off, the portion of the packaging located between the mutually associated supporting overlaps.
  • the two supporting overlaps each to be in the form of a fin-seal seam; it is also possible, however, to provide only one fin-seal seam for such a supporting overlap, while the other supporting overlap is formed by a fold which, for example, has a predetermined tearing line.
  • a predetermined tearing line can be formed, for example, along the outer edge of the supporting overlap by a line of weakness in the film forming the packaging. On opening, such a line of weakness then allows detachment of the side face of the packaging being opened.
  • At least one supporting overlap preferably two supporting overlaps defining the standing surface or all of the supporting overlaps, can have a predetermined tearing line and optionally a notch or incision arranged as a continuation of the predetermined tearing line, the predetermined tearing line being arranged on an inner boundary, facing the interior of the packaging, of the adhesive forming the supporting overlap, so that access can be gained to the interior of the packaging when the predetermined tearing line is torn open.
  • the packaging according to the invention can therefore be opened by detaching a supporting overlap along a predetermined tearing line from one transverse-sealed-seam-side end of the supporting overlap to the other transverse-sealed-seam-side end of the supporting overlap.
  • the side face of the packaging according to the invention located between the two supporting overlaps can then be folded back so that maximum access can be gained to the interior of the packaging.
  • the transverse sealed seam can also be left intact, so that the strip of packaging between the former supporting overlaps extends handle-like along the packaging.
  • Such a handle-like side strip can be utilised, for example, for suspending the packaging, which can be practical, for example, in an outdoor situation for hanging the opened packaging on the branch of a tree.
  • an opening portion between supporting overlaps preferably between two supporting overlaps, is preferably provided with at least one gripping device, for example a grip tab, such an opening portion being bounded by boundary lines, for example one or, preferably, from two to four predetermined tearing line(s) and/or peelable seam(s), especially supporting over!ap(s) in fin-seal form.
  • such a flow-pack packaging according to the invention accordingly has numerous advantages over previous flow-pack packagings, those advantages being, for example, that a packaging according to the invention is able to stand up, it preferably also being able to stand up on the narrow edges of a packaged article, and accordingly provides a display effect, which in accordance with an especially preferred embodiment of the invention can be provided not only on one side but also on both sides, since the side faces of the flow-pack packaging according to the invention can be formed without any unattractive sealed seams running lengthwise or transversely across the packaging, as is the case with flow-pack packagings in accordance with the prior art.
  • a film blank for producing a flow-pack packaging especially a flow-wrap packaging, having a longitudinal sealed seam in the form of a fin-seal or lap-seal and two transverse sealed seams
  • the film blank has a strip-shaped adhesive coating or sealing region in each of two opposite edge regions, which coatings or sealing regions are used to form the transverse sealed seams of the packaging
  • the film blank has in at least one edge region at least one strip-shaped adhesive coating which is used to form the longitudinal sealed seam of the packaging
  • the film blank also has at least two cold adhesive strips running substantially parallel to the adhesive coating forming the longitudinal sealed seam.
  • the cold adhesive in the region of the film portions forming the respective supporting seals that is to be folded the cold adhesive is arranged in such a way that, after folding and adhesive bonding of the cold adhesive in the supporting overlaps, there is no contact between the adhesive and the contained goods, since the cold adhesive is fully enclosed in, and does not extend beyond, the supporting overlap in question.
  • the film blank according to the invention is matched exactly to the size of the goods being packaged, so that a substantially exactly fitting flow-pack packaging can be produced from the film blank according to the invention. This is advantageous especially because in that way the packaging has a supporting effect on the packaged goods, and goods having, for example, a soft or pasty consistency are held in shape by the packaging.
  • the cold adhesive strips extend substantially from an adhesive coating forming the first transverse sealed seam as far as an adhesive coating forming the second transverse sealed seam, it being possible for the adhesive coating also to be a sealing medium with which the transverse sealed seams in question are formed.
