" Bags with a flickering bottom, especially for holding! Liquids "

The hiring relates to flexible or semi-rigid packaging in the form of a bag with a flat bottom, in particular a bag for holding liquids.

Liquid, doughy or powdery foods, especially Nutrient fluids, such as milk, are currently being filled more and more in bags with a flat bottom, the upper one

Subsequent opening, generally by welding, is closed. Such bags are made of a flexible or semi-rigid material such as a plastic film or, preferably, from a layer material, which is made of a resistant paper consists, which is coated on both sides with a substance, such as polyethylene, lets weld under the influence of heat. The starting material is rolled in the form of an Eohr, from which one then makes a bag, the fluffy bottom of which allows comfortable placement, and that in general parallel-flat'or prismatic lorm a space-saving Storage and shipping permitted.

The well-known bags have a through! Old and tight welding the lower edge of the corrugated flat, generally rectangular or square bottom surface, the only in several work steps or on a comparative basis complicated machines can be manufactured.

The innovation is based on the task of developing a bag, the container bottom of which is easy to manufacture and which can be stored or shipped flat before filling.

The bag in accordance with the innovation is marked with a base which is formed by a bellows consisting of at least two sections folded into the interior of the bag is whose free ligaments are firmly connected with each other, with the middle rope of the bellows to a flat bottom

is unfoldable, the outside of which becomes a kind unite ears arranged inside the bag.

The bag is preferably folded at least three times by an individual in its central region in the manner of a concertina Sheet formed, its overlapping margins are connected to each other. By spreading the middle! hatchet of the bellows to a suitable width you get a rectangular flat bottom, the side edges of which unite in the manner of internal ears connected to the side walls of the bag, which form a prismatic shape.

In the following, on the basis of the drawings, the! described by way of example in order to gain an understanding of the various Features of the innovation and the type of implementation to facilitate. Everything from the text and the Figures emerge is within the framework of the innovation.

The bag consists of a weldable sheet 1, i.e. a sheet of dense paper, which on both sides is provided with polyethylene and which has the property of creating a tight weld seam in a known manner form when the two edges placed on top of each other are heated. The sheet is like this along lines 2, 3, and 4 folded so that two surfaces 5 and 6 are formed which represent the walls of the bag and with two others ! Laughs 7 and 8 are connected, which are arranged between them like a harmonica and here form a bellows.

The free, superimposed strips are welded from one end of the bag to the other along the seams 9a and 9a 9b (fig. 2). This weld joins the edges 5a and 6a on the one hand with one another and on the other hand with the bands 7a and 8a close together, which latter are also welded to one another at the same time. The same thing happens with the edges 5b and 6b or 7b and 8b.

Fig.3 shows the middle part of the bellows 7, 8 for the purpose Spread apart to form a flat floor. This part of the surfaces 7 and 8 is essentially aligned perpendicular to surfaces 5 and 6, while the latter are converted into an approximately prismatic body by having their middle ropes two opposite one another Walls 6d, and their side areas 5c and 6c form two further, opposite! Wear mid-season 9a and 9b. The side areas of the surfaces 7 and 8 of the bellows form in this shape two ears 10, 11 inside the bag, which are welded to seams 9a and 9b, respectively.

Care must be taken that the bag, when empty, does not adopt a geometric shape with sharp angles or preserve. However, Ss can be assumed that if the perimeter of the rectangular bottom is equal to the trunk of the length of the folds 2 and 4 (minus the widths of lines 9a and 9b), the width of the rectangle is equal to the sum of the widths of surfaces 7 and 8. His On the other hand, length a is equal to the difference between half the circumference and this width.

To spread the accordion fold 7, 8 apart and one To form a rectangular flat bottom, folds 2 and 4 must be separated from each other to length a * Above In addition, the distance a must be aligned with the center of the folds 2 and 4.

Fig. 4 shows an apparatus which allows this expansion process to be carried out. She is of a kind Formed shoe trees, the two rectangular plates 12 and 13 of the width a, which with handles 12a and 13a and are articulated to one another at 14. The handle 13a is on a chassis, not shown attached, while the handle 12a by a train 15 which is operated by a pedal 16 which is mounted at 16a on the chassis. At the side of the Chassis is a guide 17 is arranged so that the bag when it is slipped over the plates 12 and and with the resulting deformation into the shape 18 'shown in dashed lines with the seam 9'a against the guide is applied, is exactly centered on the plates 12 and 13.

In the lounging position, the tensioner is not completely closed, i.e. the outer ends of plates 12 and 15 are slightly apart. Therefore, when the bag is advanced to position 18, the free ends can be seen of the plates up to the folds 2 and 4 of the bellows 7, 8. If you then press in the direction of arrow 16Td on the Pedal 16, the tensioner opens, and remove the plates 12 and 13, which are well centered in the bag from each other, taking the middle part of the old 2 and 4 with them to form the rectangular base.

It goes without saying that the type of production described is only an example and can thus be changed, in particular by introducing technical equivalents, without the scope of the invention to leave. In particular, the bellows can have more than two gaps, for example four or six. The invention is not limited to rectangular or square bottom shapes. By symmetrical! "Peculiar to the folding 2 and 4 to the axis of the sheet one could for example make a prismatic bag with trapezoidal shape or triangular bottom.

The hiring is also not limited to containers for liquids. The welds 9a and 9b could be done by others Fastening possibilities are replaced, for example by an adhesive, a seam or a hammering.
