Refillable bag.

description

The invention relates to a NachfülIbeutel with two side walls formed of films of substantially rectangular shape, which are connected in the edge region along its side edges and their upper and lower edges to form bag edges, wherein for filling and emptying in the region of the upper edge of the bag an opening made wicd.

For example, such refillable bags are offered with cleaning or washing liquids, with which bottles whose original fillings have been used up are replenished. The once purchased bottles are used repeatedly in this way. The NachfülI bags require in comparison to the bottles significantly less material, are therefore cheaper and lighter in weight and have in the filled and especially in the emptied state, in which they can be merged in their confined space due to their flexibility, a much lower PIatzbedarf.

A serious disadvantage of these known Nachfüllbeutel is that they are difficult to handle in the filled state due to their flexibility, especially in fillings with liquids. Refill bags, as they are known for example from DE-GM 76 04 889 require cartons or other supports to them without risk of

To offer or store damages on shelves, it is necessary to be able to handle their contents when decanting their contents. From DE-GM 82 05 877 are also NachzuflI booty I bekannv, which are provided at their lower • Eutelrändern with handle parts for hanging the bag during storage. Oa, however, are not always suitable for grip part hanger present / handles the handling of these known bags when hanging very often oil difficult, so that sis not hung, but on shelves, partially stacked, can be placed and thereby damaged. The Hanohabung when removing the suspended bag is difficult and brings • Deschedication by tearing the handle with «I. Furthermore, these known bags can not be stored after opening without re-closing, regardless of whether they are hung up or lying down. They must therefore be completely emptied after opening, so that their use is limited. Moreover, these known pouches are as difficult to handle as the pouches due to their flexibility in transferring their contents.

It is an object of the invention to provide a NachfülI bag of the type mentioned with improved handling and trweiterter possible use.

This is achieved according to the invention by the characterizing parts of claim 1. The refill bag according to the invention has a certain inherent stiffness emanating from its base, which makes it easy to handle it in the filled state, for example by simple gripping, be it for transport or when transferring the contents. Of the

trf i η d · / η (js 3 * * ^ e Muffle pouches can be stored in shelves in a simple manner without the risk of damage, and setting them in and out of the racks is extremely easy. With the arrangement of the opening at the upper edge of the bag with respect to the base and with the inherent rigidity caused by the latter, the advantage is achieved in a surprising manner that the fish according to the invention is open again without re-closing can be stored. In the unfilled state, the refill bag according to the invention has sufficient flexibility, which makes it possible to collapse it on the tightest little.

As a footing of the erfingsgemäßen refill bag whose lower edges are used; For this purpose, the films are preferably connected to each other above their lower edges by a foldable bottom. In this case, the edge regions in which the foldable bottom is connected to the foils can be a plano-concave surface in each case. To ensure the handling of Nachfüllbeuteln that exceed a certain height, it is advantageous to form the films as plastic composite films. The flexibility, ie the collapsibility and thus the handling, of the refill bag according to the invention are not impaired. In addition, the plastic composite film offers a flavor protection.

To improve the handling when transferring the contents of the opening is advantageously formed on a is substantially cylindrical spout, dia -joer the upper edge of the bag protrudes. In case of accidents, the spout can be inserted into the container to be filled.

Wöbe * their cylindrical design prevents jamming in the container opening. In this case, the spout may consist of two extensions of the films, which are connected together in the edge region along their edges to Tüllenrändern. Preferably, a spout edge is the rectilinear continuation of a prey side edge. This creates the opportunity to provide the upper edge of the bag with a handle, preferably an elongated handle opening, and in this way to further improve the handling.

Other measures to improve the handling without affecting the flexibility may be to form the bag edges projecting laterally outside of the bag, the upper edge of the bag so obliquely form that he with the bag side wall facing away from the spout an angle in the range of 95 ° to 120 ° , preferably from 102 ° to 113 °, and to round off the transitions between the upper edge of the bag and the spout and the side of the bag facing away from it.

In the following, the invention will be described in more detail by means of an exemplary embodiment with reference to the drawing. Show it:

F1g.1 the refill bag according to the invention in the folded state,

2 shows the refill bag of Fig. 1 in the filled state in perspective, and

3 shows a bottom view of the refill bag 1 m shown in FIG. 2 filled state.

The refill bag according to the invention consists of two plastic composite films 1 of substantially rectangular shape. Both films 1 ie the edge region of their side edges 2, their upper edges 3 and their lower edges 4 are welded together to corresponding bag edges 5, 6 and 7 respectively. The bag edges 5 and 6 are in a plane (parallel to the drawing plane of Fig. 1) laterally outward. The same applies to the folded refill bag, as shown in FIG. 1 is shown for the lower bag edge. 7

The refill bag according to the invention is designed as a stand-up pouch. For this purpose, it has a foldable bottom 8 on / in each of a lower edge region 9 of the lower edge of the film 4 is welded to the sheets 1 and a free, not welded bottom portion 10, which is folded refill bag between the two films 1 along the fold line 11th folded is arranged. The edge regions 9 represent a plano-concave surface, ie the free bottom portion 10 is attached to the sheets 1 in a concave course along the line 12.

When the refill bag is filled, the fold of the free bottom section 10 is at least partially lifted, so that both lower film edges 4 / together with the welded-on part of the foldable bottom 8 represent the lower edge of the bag 7, with an approximately elliptical course / as shown in FIG / are arranged and serve as a base of the refill bag.

The refill bag according to the invention has a cylindrical grommet 13 in an upper corner area

consists of two corresponding FoLienverlängerungen which are welded together in the edge region along their side edges to Tüllenrändern and ti it form a pouring opening 1A at their upper free ends. One of the Tüllenrinder is the rectilinear continuation of the associated bag side edge 5, while the opposite Vüllenrand is arc to the upper edge of the bag 6 connects, which also rounded in the arc merges into the associated bag side edge and between two roundings runs obliquely so that it with the spout 13 facing away from the bag side edge 5 forms an angle of 106 °. In the upper edge of the bag 6 an elongated handle opening 15 is formed.

ter refill bag according to the invention is particularly suitable for liquid media, but can also accommodate other, for example, powdery materials.
