Definitions

• the invention relates to a stand-up pouch with two side walls which are integrally connected in the edge region along their side edges to form protruding side edge strips.
• a stand-up pouch or refill pouch of this type is known from DE-GM 88 07 593. With such a bag, cleaning or washing liquids but also powders for refilling corresponding original containers, in particular bottles, are offered.
• the lower circumferential edge can serve as the base of the known refill bag, the side walls of the bag are connected to one another at the lower end by a foldable base.
• the edges of the floor can be integrally connected, in particular welded, to the lower edges of the side walls in such a way that the edges stand down as stiffened edges and form a kind of standing edge.
• a cylindrical spout is warmed to it protrudes over the top edge of the bag - i.e. opposite the bag bottom.
• a spout edge is formed as a straight continuation of one of the edges of the bag provided on the side walls. This makes it very easy to pour or pour the contents of the bag.
• the choice of material for the stand-up pouches is made in such a way that as much volume as possible of refill substance can be accommodated in the smallest space. This requires considerable flexibility for the individual stand-up pouch. However, the flexibility required for storing a large number of stand-up pouches becomes disruptive when a single pouch has to be poured into a container or, especially after partial emptying, to be set up.
• the invention has for its object to increase the stability of a stand-up pouch even further while maintaining the flexibility of the pouch for storage.
• the solution according to the invention for the stand-up pouch mentioned at the outset, with side walls integrally connected to one another at the side edges to form laterally projecting bag edges, is that the side edge strips are stiffened by a three-dimensional profile.
• the geometric deformation according to the invention of the laterally projecting bag edges - that is to say by adding a dimension perpendicular to the edge strip surface - achieves additional dimensional stability of the edge strips which in any case contribute significantly to the bending strength of the stand-up pouch and project outwards.
• the sides edge strips have a stiffening profile extending in their longitudinal direction. This increase in bending stiffness and bending moment in the axial direction, that is, in the direction parallel to the longitudinal extent of the side edges, increases the structural rigidity of the entire bag in such a way that the bag remains stable even with partial filling up to the upright pouring spout. If the side walls and other parts of the stand-up pouch are made of foil, weld seams are preferably provided for materially connecting the edges and edge strips. The object of the invention can then be described as a type of shape welding for producing rounded and / or angular stiffening ribs extending parallel to the longitudinal direction of the edge strips.
• the profile consists of at least one longitudinally extending fold line. This means that a structural stiffness can be achieved if each of the bags is edged - in the area of the integral connection - once by approximately 90 °. Ultimately, it is only a matter of making the edge protruding in strips from the bag in three dimensions. In this sense, the stability becomes even greater if the profile preferably has a single or multiple semicircular, triangular or rectangular cross section in section perpendicular to the longitudinal direction.
• a stiffening profile is provided on the bottom edge of the bag in addition to the side edges.
• a stiffening of the lower edge strips of the bag base is important for the stability of the entire bag, because the bag base is to a certain extent the foundation of the side surfaces, but in particular also the stiffened side edge strips of the bag. It is therefore particularly advantageous in the bottom area of the stand-up pouch to increase the stability and load-bearing capacity to increase the surface stiffness.
• stiffening ribs extending perpendicular to the contact surface are provided on the bottom in the lower edge strip.
• the stiffening profile of the side edge strips can extend into the area of an upper edge strip provided on the top of the bag. There then remains only an pouring spout as an opening, so that the stiffened edge strip running almost all around accordingly forms a type of stiffening frame for the stand-up pouch.
• Figure 1 is a stand-up pouch in perspective.
• Figures 2 and 3 vertical sections through a one-piece and a three-piece bag.
• Fig. 9 a filled stand-up pouch.
• the side walls consist of plastic films welded together at least on the side edges 6 and on the top edge 7.
• the bottom 5 is connected in one piece to the side walls 2 and 3. 3, the lower edges, that is to say the bottom edges 8 of the side walls 2 and 3, are welded to the corresponding bottom edges 9 of the originally separate bottom 5.
• the stand-up pouch 1 also includes the spout 4, which should be essentially cylindrical and which can consist of extension pieces 13 of the side walls 2, 3.
• the spout 4, like the entire stand-up pouch 1, can be made stable in shape with the aid of the stiffening edge strips 10 and 11, which are extended into the area of the spout, such that the pouring opening 14 belonging to the spout 4 is partially or completely filled bag 1 always stands up and remains so open that pouring is almost as possible as with a rigid wall bottle.
• the edge strips 10, 11 and 12 form the essential stiffening structure of the stand-up pouch 1.
• the structural rigidity of the stand-up pouch is increased in that, at least on the side edges 5 in the outwardly projecting side edge strips 10, a longitudinally extending 15 of the edge strips 10 to 12 extends stiffening three-dimensional geometric profile is provided.
• this profile consists of an L-bend along a fold line 16 running parallel to the longitudinal direction 15.
• a single fold line 16 of this type instead of a single fold line 16 of this type, according to FIG. 5, one can also run in the longitudinal direction 15 (FIG. 1) of the respective edge strip Rectangular fold 17 are provided.
• Another possibility according to FIG. 6 is to provide a folding with an accordion cross section, that is to say a triangular folding 18. Good stiffening can also be achieved if the respective edge strip is used as a semi-circular fold according to FIG. 7 or as a serpentine fold 20 is formed according to FIG. 8.
• the originally flat, that is to say two-dimensional, profile of the edge strips is made three-dimensional by folds or bends which act like stiffening "ribs".
• the floor according to FIG. 9 has stiffening ribs 21 which run there within the edge strips 12 approximately perpendicular to the longitudinal direction 15 of the floor edge 8 and approximately vertically.
• lateral folds are formed if the pouch is provided with a pouring spout. This effect is based on the bulging of the bag.
• the lateral edge strips 10 are stiffened according to the invention by the three-dimensional deformation mentioned above.
• the bag according to the invention since the bag according to the invention also bulges when it is filled, it pulls the film surface required for bulging out of the head region, which results in a fold-in region 23 indicated in FIG. 9 adjacent to the shoulder 22.
• folds of the bag during filling cannot be avoided.
• the measures according to the invention ensure that the folding of the bag is shifted in a defined manner into the upper region adjacent to the shoulder 22 and accordingly can no longer impair the stability of the bag.
