Definitions

  • the present invention relates to a toast bread bag made of plastic film for packaging a bread stack consisting of individual slices of toast bread.
  • Such stacks of bread have hitherto been packaged in such a way that the bread stack is encased with a plastic film along its longitudinal edges and the plastic film is joined, preferably welded, in the region of the overlaps along the longitudinal edge of the bread stack and on its two end faces.
  • This type of packaging is mechanically complex with regard to an automatic packaging process.
  • a comparatively large amount of plastic film is required.
  • the object of the present invention is to create a new type of toast bread bag which, with simplified mechanical engineering outlay, less need for plastic film, ensures better handling of the toast bread bag by the consumer.
  • the invention brings about a centering effect of the toast bread stack in the region of the conicity of the bag, as a result of which a very good pressure is produced Integration of the toasted bread stack inside the bag is guaranteed. It is only necessary for the packaging to fix the bag in place, to open it with a spreader or the like, and to insert the toasted bread stack into the tubular bag via a holding device which laterally engages the same in the form of two flat holding arms, as a result of which - as already mentioned at the beginning - in the area The taper of the bag creates a centering effect and a holding effect of the stack of bread. The part of the bag protruding from the open end of the toast bag is then gathered up and sealed with a suitable closure.
  • the bag according to the invention makes it possible to pack toasted bread at speeds which are much higher than in the prior art.
  • the mechanical engineering effort is considerably simplified compared to the prior art.
  • An expedient embodiment of the toast bread bag according to the invention is characterized in that the conical area merges into a cylindrical section towards the open end of the toast bread bag.
  • the cylindrical section is intended to ensure that the gripping devices, which are designed as flat holding devices and act on the respective side region of the toasted bread stack, can be inserted together with the stack into the tubular bag without fear of damage to the bag during its filling.
  • the width of the cylindrical section must therefore be chosen so that there is sufficient space for the holding devices. Due to the already mentioned closure of the bag on the front of the bread stack, the bag also fits closely to the bread stack in the area of its cylindrical cut, which results in an overall very compact packaging.
  • the blank expediently has two main surfaces which are connected to one another along their two longitudinal edges, are preferably welded together.
  • the toast bread bag according to the invention is particularly easy to produce as a blank in this way.
  • the conical area of the bag is correspondingly caused by an area on the blank which has a width B which is in particular continuously decreasing. Such a cut can be realized by simple means.
  • the conical area should be dimensioned such that a centering effect prevails when the toast bread bag is filled onto the toast bread stack.
  • the conical area is located in the half facing the open end, preferably one third of the total length of the bag, on the one hand means that the toast bread bag can be filled quickly and easily without the risk of damage to the wall of the bag and that the stack of toast bread is firmly enclosed Packaging produced.
  • the taper angle of the conical area is expediently in a range of 1-10 °.
  • the one-sided closure of the toast bread bag on the front side of the bag facing away from the conical region makes it possible to close the bag with force to be transmitted via the bread stack to the closed rear wall of the bag, thereby achieving a very compact packaging which tightly encloses the bread stack becomes.
  • a closure ring or a holding band can be expediently provided, with which the loose end of the packaging bag can be gathered and constricted.
  • the bottom fold described in claim 11 on the one hand brings about a good adaptation of the bag contour to the contour of the end face of the stack of bread, on the other hand the bottom fold can also be used effectively as an advertising space.
  • both side areas of the bottom gusset are preferably connected to the edges of the bag, e.g. welded.
  • a plurality of perforations can be provided according to claim 13, which allow an exchange of moisture with the outside environment.
  • the bag advantageously consists of low (LD) or high density (HD) polyethylene or of polypropylene.
  • Reference number 1 in FIG. 1 describes the toast bread bag according to the invention in its entirety.
  • the toasted bread bag 1 comprises an area 2 beginning at the open end 6 with a constant width A, which after about a third of the total length of the toasted bread bag 1 merges into an area with a continuously decreasing width B.
  • This conical area 3 ends at the closed end 4 of the toasted bread bag 1.
  • the toasted bread bag 1 has a flap 7 in the area of its open end 6 with e.g. two receiving holes 8, the exception holes having the task of including a holding device that holds a plurality of stacked toast bags during packaging.
  • the bag blank consists of two flat main surfaces 12, 13, which, for example, along their two longitudinal edges 14 are connected to one another, preferably welded to one another, the two longitudinal edges in the cylindrical region 2 running parallel to one another in the conical region 3 of the bag 1 at a certain angle.
  • the entire toast bread bag 1 can be provided with a large number of perforations 11, which is shown in FIG. 1 for the sake of clarity only as a representation of a partial section.
  • the taper angle of the conical region 3 is in a range of 1-10 °, preferably 3 °.
  • the setting of the taper angle depends however on the requirements of the toasted bread stack to be packed.
  • an inwardly folded bottom fold 5 is provided.
  • the side regions 15, 16 of the bottom fold 5 are firmly connected to the respective longitudinal edge 14 or 17, preferably welded.
  • a perforation line 19 can optionally be provided in order to be able to remove the flap 7, if necessary, without the remaining bag area being damaged during the filling process of the bag, which at the same time also increases the advertising effectiveness of the bag 1 .
  • Fig. 3 shows the toast bread bag 1 according to the invention in the state of complete packaging with content, i.e. a bread stack 10 consisting of individual toast bread slices. Due to the dimensions of the toast bread bag 1 and the conical configuration of part 3 of the toast bread bag 1, the bread stack 10 is in a state in which compressive forces act on the outer sides of the bread stack.
  • the present invention ensures considerable advantages both in terms of the mechanical packaging of toasted bread stacks and the manageability of such bags during packaging and by the end user. It therefore represents a particular advance in the relevant field of bread packaging.
  • the invention ensures that the toast bread bag can be opened and closed several times by the end user without any problems.
  • the toasted bread bag can be resealed without problems, which means that the toasted bread stack can be kept longer in comparison to previous packaging.
