Description

With a napkin stocked packaging bag

The invention relates to a packed with a napkin packaging bag for packaging food, with a front and a back layer of a

flat, flexible material and an intermediate layer of a flat, flexible and liquid-impermeable material, wherein the napkin is received between the front-side layer and the intermediate layer and wherein between the

Liner and the back lay a room for the reception of a food is made. Bags constructed in this way are known, for example, from the document DE 1 973 933. The sole figure of this document shows a closing strip 3, which protrudes laterally beyond the bag walls and is intended to close the bag opening. This bag is not suitable for machine production from band-shaped

Material, especially because the shooting strip must be retrofitted, which requires an unacceptable additional effort. Based on this prior art, the invention is based on the object to provide a packaging bag of the type mentioned, which is easy and inexpensive machine-made from strip-shaped material. For such a manufacturing process, reference is made to the document

Referenced WO 2009/043542.

This object is achieved according to the invention in that the front-side or the rear-side layer is longer than that another position to form a foldable flap for the room.

The fact that one of the layers is extended to a closure flap, the inventive

Produce packaging bags simply and inexpensively from strip-shaped material.

According to one embodiment, a cut is arranged in the front side position, which provides access to the napkin

guaranteed. This creates a spatially independent access to the napkin from the opening of the room.

According to another embodiment, the napkin protrudes through the cut to the outside. Thus, the napkin can be easily grasped and pulled out of the bag for use.

According to another embodiment, it is provided that at least the lateral edges are formed as sealing edges, in which the intermediate layer is sealed with. This measure simplifies the manufacture of the bag from endless belts. According to a further embodiment, a self-adhesive area is provided with which the closure flap can be fixed after folding on one of the layers.

According to a further embodiment, the backsheet layer is formed longer than the front side layer and folded at its end towards the front side layer and the folded part has seals on both sides, whereby a pocket is formed. The closure is achieved by the extended area of the backsheet formed flap over the front of the

Packing bag and hung with the bag at the bottom of the packaging bag. Thus is also the

Cut and possibly from this outstanding napkin covered by the flap.

According to another embodiment, the front-side layer is formed longer than the backsheet and folded at its end toward the backsheet back and the folded part has seals on both sides, whereby a pocket is formed. For closure, the closure flap formed by the extended region of the front-side layer is placed over the back of the

Packing bag and hung with the bag at the bottom of the packaging bag. Thus, the cut and possibly out of this outstanding napkin remains free, so that the napkin without opening the

Packaging bag is accessible. If according to another embodiment, the front side

Layer and the back layer are integrally folded and folded in the bottom area, the production of the packaging bag is further simplified. According to another embodiment, the

Packaging bag on a fold bottom. Through this

Measure increases the space for food intake. According to another embodiment, the bottom portion of the packaging bag for the purpose of stiffening on a seal. This facilitates the slippage of said bag for the purpose of closing the packaging bag. Finally, according to another embodiment

provided that at least one line of weakness is arranged as a tear-open in the front-side layer and / or in the backsheet. Thus, the food and / or the napkin can be easily torn open

be removed.

Embodiments of the invention will be described in more detail below with reference to the accompanying drawings, for example. It shows a perspective view of a first

All figures show embodiments in a position in which they can be advantageously made of band-shaped material, wherein the bands each extend in the figure in a direction from top to bottom. In general, the bottom of the bag is shown on the left and the opening for filling on the right in the respective figure.

The packaging bag 1 shown in FIG. 1 has a front layer 3 and a back layer 4 of a flat, flexible material, for example paper. Through a cut 2 in the front side layer 3 a napkin 5 protrudes. As illustrated, the cut 2 can run continuously from one side edge of the packaging bag 1 to the other, as a result of which a section 3a is separated from the front-side layer 3. With 12 is one

Opening edge of the packaging bag 1 denotes. In this embodiment, the backsheet 4 projects beyond the front side layer 3 and forms a closure flap which projects in the direction of the arrow 14 over the opening edge 12 and over the section 2 from which the napkin 5 protrudes,

can be folded. Adjacent to the section 2 is an adhesive strip 13 for holding the closure flap

arranged. Alternatively, the adhesive tape could also be arranged on the closure flap. Alternatively, the

Shutter also be formed shorter, so that their free end would come to lie in the folded state above the napkin 5 in the region of the portion 3a and thus the protruding end of the napkin with closed

Packaging bag would not be covered by the flap. At the side edges, the front-side layer 3 and the backsheet 4 are joined together by sealing edges 10, 11. FIG. 2 shows the packaging bag according to FIG. 1 in a sectional view, wherein the section runs along a horizontal line in FIG. In this embodiment, the front-side layer 3 and the back-side layer 4 are formed from a one-piece, folded-over sheet, wherein the

Bottom 6 of the packaging bag 1 may be formed as a fold bottom. A liquid impermeable intermediate layer 7 extends from the bottom 6 of the packaging bag 1 to close to the opening edge 12 and can there in a sealing area 8 with the front side layer 3 and with the

Section 3a be connected. Sideways, the intermediate layer 7 is advantageously integrated into the sealing edges 10, 11, so that the intermediate layer 7 of an endless belt in one operation with the front side layer 3 and the

Backside 4 can be made. It can be seen that the napkin 5 is disposed between the front sheet 3 and the back sheet 4 and advantageously protrudes through the cut 2 so that it can be easily grasped and pulled out. Clearly visible in this figure is also a between the liner 7 and the

rear layer 4 formed space 22 for receiving a food to be packaged.

Figures 3 to 5 show a bag similar to Figures 1 and 2, but much wider to receive an elongated food such as a sandwich. The flap is also formed in this embodiment of the backsheet 4, but is longer than in the embodiment of Figures 1 and 2. At the free end of the flap, a pocket 20 is formed by folding the backsheet 4 and attaching side seals 21 , Will the

Turned flap in the direction of arrow 15, it extends to a bottom seal 18 and covers it Both the opening edge and the protruding from the section 2 napkin 5. The bottom seal 18 is used

in particular for stiffening the bag edge in this area and can also be attached if the

front layer 3 and the back sheet 4 are integrally connected to each other and even if a

Pleat bottom 6 is present. FIG. 5 is a

Starting from the bottom seal 18, the backsheet 4 extends counterclockwise about the sandwich 22 around, covering both the opening edge 12 and the from the

2 cut napkin 5, in turn reaches to the

Floor seal 18 and is slipped over the bottom seal 18 with the present at its free end pocket 20. So that the bottom seal 18 easily finds room in the pocket 20, it has lateral bevels 19 (Figure 3). The intermediate layer 7 protects the napkin 5 before

Moisture that could escape from the sandwich 22.

FIG. 6 shows a third embodiment of the invention

Packing bag differing from the previous ones

described embodiments differs in that the front-side layer 3 projects beyond the backsheet 4 in the region of the opening edge 12 to form a relatively short flap. The latter is to be folded in the direction of the arrow 16 and is fixed by means of an adhesive strip 13 on the backsheet 4. In FIGS. 7 and 8, a fourth embodiment of the packaging bag is shown, which is constructed similarly to the second embodiment, with the difference that the closure flap is formed not by the backsheet 4 but by the front side layer 3 according to the arrow 17 in Figure 7 is to be moved. As can be seen particularly clearly from FIG. 8, this difference has the consequence that one end of the napkin 5 is exposed even when the packaging bag is closed. Starting from the bottom seal 18, the front-side layer 3 extends clockwise around the sandwich 23, wherein at the top in the figure, the between the front side layer 3 and the

Interlayer 7 recorded napkin 5 protrudes through the cut 2 to the outside. From there, the front side layer 3 continues over the opening edge 12 to the bottom seal 18, over which the bag 20 is slipped and thereby the

Closes packaging bag. This closure

works without the aid of glue and can be opened several times and closed again.

In particular, in the embodiments according to Figures 1, 2 and 6, in which the closure flap by means of a

Adhesive tape is held in the closed position, advantageously at least one of the layers 3, 4 a perforation or lines of weakness for easy tearing of the
