Definitions

  • the invention relates to a bag arrangement having a row of pouches with a plurality of pouches lined up in the longitudinal direction of the row of pouches, wherein a pouch has an opening side with an opening, a bottom side and two longitudinal sides running parallel to the longitudinal axis of the pouch. Furthermore, the present invention relates to a method for producing such a bag arrangement.
  • a bag arrangement of the aforementioned type for freezer bags is already known from practice.
  • the individual bags in the bag row are arranged one behind the other.
  • the bag row with the majority of the bags is made of a tubular film.
  • transversely extending to the longitudinal direction of the bag row transverse welds are provided, each representing the lower closed end of a bag.
  • a perforation is provided parallel to this, which serves to tear a bag from the row of bags.
  • At the separated via the perforation side of each new opening side of the bag is formed, via which the respective bag is opened.
  • a disadvantage of the known bag arrangement is that on the one hand just the opening side, which is handled by the user to open the bag, due to the tear at the perforation optically-aesthetically less appealing.
  • the object of the present invention is therefore to avoid the disadvantages occurring in the prior art.
  • the longitudinal axes of the bags are arranged parallel to one another and transversely to the longitudinal direction of the row of bags.
  • the invention is characterized in that the individual bags in contrast to the prior art in the bag row not in a row, but next to each other.
  • the openings or the opening sides are provided laterally on the row of bags, so that a tearing of a bag from the row of bags does not lead to a tearing of the opening side. Since the openings are provided laterally on the row of bags, they can also be better open.
  • the opening has two opening edges.
  • the invention allows one opening edge to project beyond the other opening edge to form an opening lip.
  • Another advantage associated with the present invention is that a bottom fold is provided on the bottom side.
  • the bottom fold is folded into the interior of the bag and designed so that it forms a floor in the extended state.
  • the formation of the longitudinal sides of a bag according to the invention differs from the prior art.
  • the bag of the bag arrangement according to the invention and thus for forming the longitudinal sides transverse transverse to the longitudinal direction of the bag row transverse welds are provided.
  • perforations are provided which extend over the entire width of the row of bags. Although there is a rather non-uniform tear-off edge over the perforations, this is less conspicuous in the invention, as this odd tear-off edge is provided on the already less respected side margins.
  • At least one tear-off opening is provided in the region of the perforation, which should be designed as a punched-out.
  • the punching results in a passage opening having a maximum width of greater than 0.5 mm, preferably greater than 1 mm.
  • the tear-off should have such a length that can be intervened easily with a finger.
  • the invention can be applied to bags of any kind.
  • the invention is suitable for handle opening freezer bags, which are regularly and frequently consumed in private households and accordingly must be easy to tear off and open.
  • Bag arrangements of the aforementioned type are usually offered in a package.
  • bags with different sized side lengths, uniform packaging or at least the same packaging lengths it makes sense that the opening side is folded along a direction parallel to the longitudinal fold line. This results in an envelope, which rests on an outer flat side.
  • This envelope can vary in size depending on the bag size. In any case, this folding ensures that that the unfolded part is always the same even with different bag lengths.
  • the present invention relates to a method for producing a bag assembly of the aforementioned type.
  • the production method of a bag arrangement with a row of pouches having a plurality of bags lined up in the longitudinal direction of the row of pouches is preferably designed such that a flat film is folded over in the longitudinal direction and transverse welds oriented transversely to the longitudinal direction are provided.
  • the transverse welds define the individual bags, the bottom side being formed by the envelope of the flat film. At the ends of the film results in the opening side with the opening of the bag.
  • the bottom fold described above is folded.
  • the above-mentioned opening lip can be readily realized in that the flat film is handled at the opening side to form the protruding opening lip, that is not folded in the middle.
  • a continuous transverse perforation is introduced between the transverse welds of adjacent bags, whereupon tear-off openings are subsequently punched through in the region of the perforations.
  • the opening side is folded over along a folding line running parallel to the longitudinal direction. Whether or not such a folding is necessary ultimately depends on the length of the individual bags or the width of the bag arrangement.
  • the row of bags of the bag assembly according to the invention is rolled up into a salable supply roll, so that the rolled up Bag assembly can be arranged in a salable packaging.
  • a part of a bag assembly is shown with a row of bags 2.
  • the bag row 2 has a plurality of juxtaposed bags 3.
  • the individual bags 2 are lined up in the longitudinal direction L of the bag row 2 together.
  • Each individual bag 3 has an upper opening side 4 of an opening 5, a lower bottom side 6 and two longitudinal sides 7, 8 extending parallel to the longitudinal axis A of the bag 3.
  • the longitudinal axes A of the individual bags 3 are aligned parallel to one another. Due to the parallelism of the longitudinal axes A it follows that the individual bags 3 are arranged transversely to the longitudinal direction L of the row of bags 2. The juxtaposed bags are all aligned in the bag row 2 with its opening side 4 to the same side. The opening sides 4 of the individual bags 3 are therewith On the other hand, all bottom sides 6 are located on the other longitudinal side 10 of the row of pouches 2.
  • Fig. 1 further illustrates that the opening edges 11, 12 of the opening 5 at the upper opening side 4, which result from the stacked flat portions 13, 14 of the bag 3, are formed in a straight line. From Figs. 1 and 3 it follows that the one opening edge 12 projects beyond the other opening edge 11. By this supernatant results in an opening lip 15, which allows a gripping and thus a very easy opening of the bag 3.
  • Figs. 2 and 4 shows that on the bottom side 6 of each bag 3, a bottom fold 16 is provided. This is inwardly, that is folded into the bag interior 17 inside.
  • Fig. 4 shows that the bottom fold 16 can be unfolded and pulled out and thus forms a floor, which makes it possible to put a bag 3 upright and to hold in this position without further aids.
  • the individual bags 3 are bounded transversely to the longitudinal direction L of the bag row 2 transverse welds 18. Between adjacent transverse welds 18 of adjacent bags 3 is in each case a perforation 19, which extends over the entire width of the row of bags 2.
  • the individual perforations 19 run parallel to each other, transversely to the longitudinal axis L and thus also parallel to the transverse welds 18th
  • a tear-off opening 20 is provided in each case in the region of the perforation 19, into which it is easy to intervene with a finger, which favors the tearing off.
  • the length of the tear-off opening 20 should be between 1 cm and 3 cm.
  • the maximum light width of the tear-off opening 20 is greater than 0.5 mm. In any case, the tear-off opening 20 is more than just an incision in the region of the perforation 19.
  • the bag assembly is folded in the region of the upper opening side 4, along a fold line which is parallel to the longitudinal direction L.
  • the longitudinal side 9 is not outside, but is located on one of the flat areas 13, 14.
