Bags, in particular carrier bags

The invention relates to a bag, in particular a carrier bag, the side walls of which are provided with a thermal insulation layer and that by folding the two together superimposed upper edges can be closed.

The well-known bags of this type, which are used to transport frozen Food, ice cream and the like have a heat insulating layer made of foam plastic. This foam plastic has elastic properties and has a relatively high resilience, so that the buckling of the upper edge produced the closure of the bag

opens easily by itself and the thermal Isolation is being challenged.

The object of the invention is to avoid these disadvantages and to provide a lock that is very simple and inexpensive to manufacture to create the roll closure that prevents the bag from opening by itself, but as often as required opening and closing of the bag is permitted.

This object is achieved with the invention in that at least one broad side of the bag with wire inserts provided, flexible clamping strips are attached, which the Hold the upper edge bent several times in the closed position.

This embodiment has the advantage that the closure formed by folding the upper edge of the bag through the clamping strips is prevented from jumping up. Nevertheless, the bag can be opened quickly at any time so that the contents can be checked ader · o4y further Ti ^ f refrigerated goods inserted or removed can be. The bag can then be closed again in a simple manner.

e.g.

The clamping strips can / with a pressure-sensitive cold adhesive provided and glued to the broad side of the bag. Special gluing devices are at It is not necessary to attach the clamping strips and these adhere fully to the surface of the bag.

According to the invention, however, the clamping strips can Kink line should be arranged parallel to the upper edge, broadside protrude over the narrow sides of the bag and are folded around the edges of the narrow sides. This allows the Closure after turning over the upper edge of the bag by simply bending the clamping strips around the side edges of the Reliably secure the bag.

The clamping strip can also extend over the entire width of the Stretch bag. This experiences at the same time a certain stiffening in the area of its upper edge, the is desirable for the transport of pressure-sensitive goods. It is particularly useful to have the upper ones lying on top of one another Fold over the edges of the bag twice and place the clamping strip between the two crease lines. By double Turning the upper edge creates a roll closure, which ensures absolute tightness, because the lower edge with the the end of the clamping strip folded around the side edge of the bag is clamped tightly to the bag.

In another embodiment of the invention, the clamping strips extend perpendicular to the top edge of the bag and are bent over together with this. This arrangement has manufacturing advantages, since the clamping strips extend in the direction of travel of the bag and can be glued to the bag with the handles in one operation. Furthermore, the clamping strips do not protrude over the edge of the bag, so that they are not in the way of storage, not for-

be able to buckle in good time and no one can injure themselves on them can.

In this case, the clamping strips are preferably under attached to the handles in the alignment of the carrying handle on the bag.

The invention is explained in more detail by means of the drawing of exemplary embodiments. It shows:

Fig. 1 shows an open carrier bag according to the invention in an oblique view and

F? G. 2 the 3bag according to FIG. 1 in the closed state in a partial side view,

3 shows another embodiment of the invention also in an oblique image and

FIG. 4 the half-closed bag according to FIG. 3 in a partial side view.

In Fig. 1 and 2, 10 denotes a carrier bag with a suitable heat insulating layer, for example is lined with polystyrene and in the vicinity of its upper edge 11 has two crease lines 12 and 13, which are parallel to the upper edge 11 and along which the two superposed upper edges 11 of the bag 10 twice be bent over so ^ Ctaß "You ^ form aόΐΓ roll closure

(Fig. 2).

Between the kicks 12 and 13 are on a broadside 14- of the bag 10 two with wire inserts 15 provided Clamping strip 16 with a pressure-sensitive cold ' adhesively bonded, which protrude on both sides over the narrow sides 17 of the bag 10 and around the edges 18 of the narrow sides 17 of the bag 10 can be turned over. Instead of of the two clamping strip pieces 16 can also be one over the entire width of the bag 10 continuous clamping strips be glued, which protrudes laterally over the bag.

As can be seen in Fig. 2, the upper hand 11 of the bag is first around the crease line 12 and then around the crease line 15 folded down. This results in a roll closure in which the clamping strips 16 in the Kink line 12 lie between the two lobes of the edge. The laterally protruding ends are then around the side edges 18 of the bag are passed around and bent over against the rear broad side of the bag 10. Through this the lock is secured, but can be opened again at any time by bending the ends of the clamping strips will.

In the embodiment shown in Fig. 3 and 4-. are the clamping strips 16 on a broad side of the bag Glued perpendicular to the upper edge. They extend in alignment with the carrying handle 20 of the carrying handle 19 and close

with the upper edge 11. After filling the bag 10, they are folded over twice together with the upper edge, so that a roller shutter is created that cannot open again by itself, but can be easily bent back can be opened again and closed again.

The invention is not restricted to the exemplary embodiments. For example, it is also possible for the in 3 and 4 illustrated embodiments clamping strips to be attached to both sides of the carrying bag. It is also possible for those running perpendicular to the upper edge 11 To combine clamping strips 16 with clamping strips running parallel to the upper edge, without this the scope of the invention is exceeded.
