Title: Insulated Bag. f

The innovation relates to an insulated bag, a plastic film consisting of j outer jacket, bottom, top part | * and feed bag, one between the outer sheath and feed \ sack provided flexible insulating layer and a
cardboard reinforcement and insulation provided on the inside of the floor.

Such knownisolation bags point to the increase
their stability is essentially rigid
Floor on. The long walls of the bag are made of cardboard
reinforced and also relatively stiff. the
Cross walls of the bag, however, and also the lid part
are flexible. Disadvantage of the known insulating bag
it is now that these take up a relatively large amount of space during storage and transport, which is particularly important when storing and transporting large quantities of such insulating bags.
Although the known insulating bags have a certain flexibility, they cannot be folded flat because of the rigid bottom. j

The innovation is based on the task of creating an insulating bag of the type mentioned above, which is
on the one hand can be folded flat for storage and transport and on the other hand an im in use
essentially rigid, increasing the stability
Has soil.

According to the innovation, this is achieved in that the base can be folded approximately in the longitudinal center plane of the pocket along a fold line extending in the longitudinal direction of the base and that the cardboard reinforcement has a fold groove with a ± m cross-section or is interrupted along this fold line and that a loose, essentially rigid, completely or partially made of insulating material is provided, the outline of which corresponds to the inner cross-section of the flap and which can be inserted into the lower part of the bag before it is used.

For storage and transport of the bag, the loose shelf is inserted into the inside of the bag, that its greatest dimensions are parallel to the side walls of the pocket. Thanks to the bottom of the bag provided folding line, the bottom can now be folded up, although it is provided with a cardboard reinforcement and the side walls of the bag come to rest on each other. The folded flat Bag takes up relatively little space. When storing and transporting large quantities This is a major advantage of this bag because it saves storage space and cargo space. Before using the bag, the essentially rigid shelf is now in the lower part of the Bag inserted in such a way that its greatest longitudinal and transverse dimensions are perpendicular to the side walls and extend parallel to the ground. This will stretch the previously folded bottom of the bag and the Rigid shelf is used to stiffen and reinforce the bottom of the bag. The bag hereby receives their desired stability. When you continue to use the bag, the shelf can always be in remain in this position or the bag without it

The content is to be transported in a space-saving manner, to be removed from its position of use.

Further advantageous refinements of the innovation emerge from the subclaims.

The innovation is explained in more detail on the basis of several exemplary embodiments shown in the drawing.

Show it:

2 shows a cross section through a second exemplary embodiment of a shelf

Fig, J shows a cross section through a second embodiment the insulating bag

Fig. 4- shows a cross section of a collapsed insulating bag.

In the drawing, 1 denotes the outer jacket of the insulating bag made of plastic film, which is connected to the also made of plastic film bottom 2 is firmly welded. The weld 3 is ^ as well as further weld seams indicated by a horizontal line for clarity. For clarification are also the various parts of the bag that lie close to one another when in use are drawn at a distance from one another. To reinforce the bottom 2, two cardboard parts 4, 5 are provided, which are expediently supported by an intermediate film 6 are covered. This intermediate film 6 is welded to the bottom 2 in the edge region

f and also along the fold line F by means of the sweat

seam 7. The fold line F extends about in the longitudinal center plane the pocket in the longitudinal direction of the same. Between the outer jacket 1 and the one made of plastic film Feed bag 8 is also an insulating layer

'9 made of flexible foam material is provided.

There is also a loose shelf 10. This loose shelf can preferably be made of a hard foam

[} plate 11 exist, the outline of which corresponds to the inner cross-section

corresponds to the bag. To a contamination of the rigid foam to prevent this is covered with a sleeve 12 made of plastic film. This sheath 12 can be

; be moderately connected to the feed bag 8 or a part

of the feed bag. In this way it is prevented that the shelf 10 is lost. In Figures 1 and 3 is the shelf - each drawn in the position of use of the bag.

For storage and transport of the bag, the insert bottom is arranged in the bag in such a way that it, like

can be seen from Figure 4-, with its largest

ί stretches extending parallel to the side walls of the bag. Thanks to the fold line and the flexible transverse walls of the bag, it is now possible to place the longitudinal walls of the same close together and the bag then takes

only takes up relatively little space. Before using the bag, the shelf 10 is in the in Figure 1 shown position brought. Here, the shelf 10 pushes the two side walls apart and he spans the floor 2. The shelf 10 is used to stiffen and reinforce the floor.

In the embodiment shown in Figure 2, the shelf 10a is also with a cover 12a encased. The shelf 10a consists of an upper one

Cardboard insert 13 and a lower cardboard insert 14-, intermediate Both cardboard inserts are insulated with a shaft Arranged from flexible foam.

In order to save on sheathing the shelf, it can also be used, as shown in FIG is to be provided between a feed bag 8 'loosely arranged in the bag and the bottom 2' of the bag. Here, the shelf 10 'is expediently made of rigid foam. To the bag for storage and The loose feed bag can be folded for transport 8 'pull up a little and then the shelf 10 Fold up and push up until it assumes the position shown in FIG. The flexible one and the feed sack 8, which is cut relatively wide, allows the insert base 10 'to be both in the transport position as well as to bring it into the position of use.

With reference to FIG. 3, it should be explained that the cardboard reinforcement 16 in the base can also be made in one piece. In this case, the cardboard reinforcement has a folding groove 17 with a weakened cross-section along the fold line F. In order to keep the cardboard reinforcement 16 always in its correct position, the above-mentioned intermediate film 6 ^{1 is also} provided, which is welded to the bottom 2 ' in the frost at the edge. The folding groove 17 also allows folding of the bottom part.
