Definitions

  • the invention relates to a food packaging bag, comprising at least a front part and a back part, which are connected to each other at least one lateral fold or fold at the two lateral edge regions and between which a pouch pocket is formed with an upper open end and a lower closed End, wherein the entire packaging bag has a left and a right bag part, both of which are interconnected along a running between the lower and upper end overlap region, in particular the congruent over the entire height of both the front and back.
  • the lower closed end may be formed by the front part is folded over at a lower fold or a lower fold to the rear on the back part and, for example, attached to this, z. Eg by gluing or welding.
  • Packaging bags for foods of this type are known in the art, for example in an embodiment in which a left-hand bag part is formed from a transparent film and a right-hand bag part is made from a paper material or vice versa.
  • Such bags offer, for example, the advantage that a in such a packaging bag packaged food despite safe absorption in the bag from the outside well visible through the clear film part.
  • bags of this type have the disadvantage that a food packaged therein, e.g. a sandwich, usually can only be removed through the open end, but not such a bag can be opened defined.
  • Careless tearing can entail an undesirable result with such bags even if they have a line of weakness, in particular a completely uncontrolled tearing of the bag and thus even the danger that the food packaged in it falls out in an uncontrolled manner.
  • bags of the type mentioned above which are formed by a left and a right bag part by connecting the two parts further such that it also in an uncontrolled or careless tearing a defined removal of a part of however, the whole of the packaging bag can be allowed, especially in the way that the foodstuff remains safely and hygienically enclosed with the remaining part of the bag and can be held by hand, but allows the food to be eaten after removal of a bag part.
  • the directional information used herein refers to a pouch position where the open end of the pouch is positioned at the top.
  • this object is achieved in that in a packaging bag of the type mentioned in the overlap area or laterally adjacent to this at least one line of weakness is provided at which the two bag parts are separable from each other.
  • a line of weakness extends in the same way as the overlap area and parallel to it, i. completely over the entire height from the lower end to the upper end on the front and back.
  • An essential aspect of an embodiment of the invention is based on the fact that it is exploited that results in a material reinforcement by the overlap of the two bag parts in the overlap region mentioned above, essentially in that here the position of the material of the left bag part with a layer of the material of the right part of the bag is connected and thus always here a thicker or stronger accumulation of material results than in the other areas of the packaging bag, in which the material is always present only in simple strength.
  • such a closed bag according to the invention can be torn open particularly easily if it is held in such a way that the one bag part is gripped by hand, for which the bag can be previously rotated by about 90 °, and then the other bag part with all the fingers of one hand to seize and to disconnect it with a tearing of the held in the other hand bag part.
  • a packaging bag of the type mentioned can provide the advantages described on the one hand the strengthening of the material in said overlap area and on the other hand, the weakening of the material by a line of weakness, for example, both bag parts of the same material in terms of all material properties, so for example both bag parts made of paper or a paper composite material or made of plastic or plastic composite material.
  • a bag part made of plastic, in particular of a transparent film and the other bag part may be made of a paper.
  • composites of several layers can also be used in each case for the materials.
  • both bag parts made of paper, but in different thickness and / or type of paper.
  • both bag parts may be made of plastics, for example of transparent films, but also different in terms of strength and / or type.
  • an inventive packaging bag of this type realizes a higher tensile strength in the one bag part with the already more tear-resistant material and especially in the overlap region of both materials, where by the material reinforcement due to the overlap even higher tensile strength compared to the simple material is achieved and then continue to have a very strong Weakening in that the weakening line at which the tearing process is to take place is arranged in the weaker material, which in particular is easier to tearing down, of both materials.
  • the weakening line is arranged in the overlapping region of both bag parts, but preferably then such that it is arranged laterally next to a connecting line or joint line, where the two bag parts are interconnected z.Bsp. by gluing, welding, embossing or other process steps.
  • the line of weakness is located in that material, which at the front part is overlapped by the other material, that is in consideration of the front part in the rear material.
  • the weakening line is arranged in the overlapping region under the overlapping material.
  • a line of weakness thus arranged is thus covered by the overlapping material, which means protection of the line of weakness and e.g. can then be particularly advantageous if a weakening line is formed as a perforation.
  • the line of weakness is closed by the overlap of the line of weakness so that e.g. Liquids such as oils, fats or sauces or other food coatings, even if they pass through the perforation line, do not escape to the outside.
  • a weakening line in at least one of the two bag parts is arranged immediately laterally adjacent to the overlapping area, thus extending parallel to the overlapping area between the upper and lower ends, in particular both on the front and side of the back , it is understood that, preferably, the distance between the weakening line and the overlapping area is smaller than the width of the overlapping area, in particular smaller than 10 mm, particularly preferably smaller than 5 mm.
  • the overlapping area basically refers to the area in which the materials of the two bag parts overlap, thus So a two-ply of the packaging bag is given in this area.
  • An overlapping area is thus limited in each case to both bag parts through the edge of the respective other bag part.
  • Weakening lines in the sense of the invention may be formed by any means suitable for causing a linear weakening of a bag part in order to define a tear line.
  • this is achieved, e.g. by forming a perforation in the material of at least one of the two bag parts in or laterally adjacent to the overlap area.
  • a perforation to provide a dilution of material to weaken the material at the thinned points and to reduce tearing here.
  • a line of weakness is formed by a linear, releasable connection along which the bag parts are connected to each other in the overlapping region, for example by gluing, welding or embossing. Such a weakening line lies in the overlapping area.
  • Such an embodiment has the advantage that in the production of a packaging bag of this type no manufacturing step for producing a line of weakness in addition to the step of connecting the two bag parts must be provided.
  • such a detachable connection which thus extends along the overlapping area in the latter and connects the two overlapping areas of the two bag parts, may be formed by a broken glue line comprising a plurality of individual glue dots or individual glue line sections. This results in this case along the connecting line thus areas within the overlap where a connection of the overlapping areas is given, as well as areas where the two bag parts overlap each other only loosely.
  • an adhesive line can also be made of an adhesive, in particular a weak adhesive, which allows the non-destructive separation of a bag part from the other.
  • a weak adhesive is thus understood to mean such an adhesive which permits this aforementioned non-destructive separation. It can be e.g. act for pressure-sensitive adhesive, as are known in similar manner from sticky notes and ensure a sufficiently high adhesion between the bag parts at the time of packaging a food, but allow in a tearing the secure release of a bag part of the other. In the present case, preference is given to using an adhesive which is approved in the food sector and / or for consumer goods.
  • a connecting line from a plurality of embossing points, which are arranged in a line-like manner one behind the other, on which the overlapping bag parts are each stamped into one another.
  • the material of a bag part can be passed in an embossing step through the material of the other bag part, so as to produce the connection of the overlapping bag parts in the overlapping area.
  • an interrupted weld seam of a plurality of individual weld points or weld line sections or even a weak welded connection in the above-mentioned sense can be generated.
  • the linear releasable connection can be released with a tearing force that is less than a force needed to destroy the material of each of the two bag parts. This ensures that, in a tear-off operation in which one of the two bag parts is pulled relative to the other, the two bag parts are most likely to separate from one another at the detachable connection without tearing open inside the material of one of the two bag parts.
  • the overlapping area in particular an edge of the overlapping area or a connecting line arranged in the overlapping area both Bag parts or a weakening line which is arranged in the overlapping region or immediately adjacent to this, is arranged at 45% to 55% of the width of the packaging bag, in particular at exactly 50% of the width.
  • the optionally selected aforementioned element preferably runs essentially centrally with respect to the width of the packaging bag so that a substantially half-way division of the packaging bag into a left and a right bag part results, which can be separated from one another are by any of the above mechanisms.
  • the width of a packaging bag is selected such that it is larger, for example at least 50% larger than the food to be packaged therein, so that the food in a packaging process substantially predominantly in one of two bag parts can be positioned, the bag is then closed, for example, by turning an optionally provided lid flap, then a person can hold the packaging bag so that with one hand the packaging bag with the food contained therein, for example, a bread is taken and with the other Hand the empty in a particular large area other bag part, so that this bag part can be taken over a large area and subjected to a tensile force against the other bag part, which causes the tearing off of this bag part according to one of the prescribed mechanisms.
  • the back part for reinforcing the lower closed end has a lower fold which lies in the fold or the fold of the front part, with which the front part on the Back part is folded. This results in the lower end of the bag, a multi-layered material and thus a gain.
  • the packaging bag which preferably has a lid flap, in that the upper edge of the back part is made higher than the upper edge of the front part, it can be provided in width in a left and a right bag part with respect to the division of the packaging bag. that in the lid flap in one of the two bag parts to one side of the overlap region, if necessary also in both bag parts on both sides of the overlap region a recess, for example a punching is arranged, which is glued from the side of the back with a sticker with its adhesive surface through the Recess or the punching through acts.
  • this recess or punching in the stronger or more tear-resistant material of both materials of the two bag parts, if different materials are selected or regardless of the choice of material in those bag part, after the tearing of the other bag part the food / Food surrounds and keeps ready for consumption.
  • the sticker has on its non-adhesive back a coating, in particular an adhesive-repellent coating, which may be provided to be contacted by the adhesive surface of a stacked on the packaging bag further packaging bag, so that through the Stacking of packaging bags of this type according to the invention, a packaging bag stack can be formed, in which the adhesive surface of one of the bags is protected by the adhesive-repellent coating of a bag below or depending on the viewpoint, until the bag is taken from the stack and for the purpose of Packaging is used.
  • a coating in particular an adhesive-repellent coating
  • Such a packaging bag of this type according to the invention is thus classified as particularly hygienic, without the need for an additional peelable protective film for the adhesive surface.
  • a gusset or both gussets, the front and back part connect laterally, in particular the gusset of the bag part that surrounds a food / food after removal of the other bag part and / or in the lid flap has the pasted recess and / or made of paper or the stronger of both materials, protruding beyond the upper edge of the front part.
  • the packaging bag according to the invention or the remaining bag part of the packaging bag according to the invention thereby has a better tightness, which is particularly important in food / food containing sauces. Also, the stability is increased, so that the remaining bag part can be easily placed on a table when the gusset, which then forms the bottom, is easily opened.
  • the protruding part of the gusset may, in one embodiment, protrude to the upper edge of the back part and thus correspond in height to that height of the back part.
  • the part of the side fold protruding beyond the upper edge of the front part has a length which is 20% to 80%, preferably 30% to 60%, more preferably 45% of the length of the cover flap or the distance of the upper one The edges of front and back correspond. Such a length is sufficient for stabilizing and improving the tightness without stiffening the lid flap too much.
  • a gusset which connects the front part and the back part has approximately a W shape in cross-section in the region in which the front part and the back part are connected to this side gusset. In the area of the gusset in which this projects beyond the edge of the front part, the gusset lacks the connection to the front part and thus one of the W-legs of the aforementioned W-shape.
  • the gusset has a pleat part connected to the front part and a pleat part connected to the back part. In the unopened state of a bag according to the invention these fold parts lie on each other. These two folding parts can each have exactly the same width, which corresponds to half the total width of the gusset.
