Abstract

The invention relates to a receptacle ( 10 ), in particular a flexible bag ( 10 ) made of paper, with a front part ( 20 ), a back part ( 30 ) and a bottom ( 50 ), which is closed by a bottom unit, and with an opening ( 1 ) lying opposite the bottom ( 50 ), wherein the bottom unit has a bottom portion ( 120 ) of the front part ( 20 ) and a bottom portion ( 130 ) of the back part ( 30 ), the bottom portion ( 130 ) of the back part ( 30 ) is shorter than the bottom portion ( 120 ) of the front part ( 20 ), such that the bottom portion ( 120 ) of the front part ( 20 ) is secured directly on the back part ( 30 ) by turning the bottom unit ( 100 ) back along a fold line ( 101 ), and the opening ( 1 ) is formed by a peripheral edge ( 2 ) which extends at a height of the front part ( 20 ) and of the back part ( 30 ) and which is at least partially frayed, thereby reducing the danger of injury at the edge ( 2 ).

First claim

What is claimed is:

1. A receptacle ( 10 ), comprising a flexible bag ( 10 ) made of paper, having a front part ( 20 ), a rear part ( 30 ) and a bottom ( 50 ) which is closed by a bottom unit, and having an opening ( 1 ) which is located opposite the bottom ( 50 ), wherein the bottom unit comprises a bottom portion ( 120 ) of the front part ( 20 ) and a bottom portion ( 130 ) of the rear part ( 30 ), the bottom portion ( 130 ) of the rear part ( 30 ) is realized in a shortened manner in relation to the bottom portion ( 120 ) of the front part ( 20 ) such that the bottom portion ( 120 ) of the front part ( 20 ) is fastened directly on the rear part ( 30 ) as a result of turning the bottom unit ( 100 ) along a fold line ( 101 ), the opening ( 1 ) is formed by a peripheral edge ( 2 ) which extends at a height of the front part ( 20 ) and of the rear part ( 30 ) and which is frayed at least in part, as a result of which the risk of injury on the edge ( 2 ) is reduced, the edge ( 2 ) is frayed in a manner of both a perforation defined by a weakening on the paper without a cut through the paper and being torn off along the perforation;
wherein a handle opening ( 4 ) is punched out on the front part ( 20 ) and on the rear part ( 30 );
wherein in a region of the handle opening ( 4 ) an inside ( 22 ) of the front part ( 20 ) and an inside ( 32 ) of the rear part ( 30 ) comprise a reinforcement strip ( 5 );
wherein the reinforcement strip ( 5 ) is at least partially punched out at the same time as the handle opening ( 4 ) is punched out.

2. The receptacle ( 10 ) as claimed in claim 1 , characterized in that the edge ( 2 ) is realized in the manner of a perforation line defined by a weakening on the paper without a cut through the paper and being torn off along the perforation line.

3. The receptacle ( 10 ) as claimed in claim 1 , characterized in that the bottom portion ( 130 ) of the rear part ( 30 ) and the bottom portion ( 120 ) of the front part ( 20 ) comprise a frayed edge ( 123 , 133 ) realized in a manner of a perforation defined by a weakening on the paper without a cut through the paper and being torn off along the perforation.

4. The receptacle ( 10 ) as claimed in claim 1 , characterized in that the front part ( 20 ) comprises an outside ( 21 ) and an inside ( 22 ) and the rear part ( 30 ) comprises an outside ( 31 ) and an inside ( 32 ), wherein the inside ( 22 ) of the front part ( 20 ) faces the inside ( 32 ) of the rear part ( 30 ), wherein the bottom portion ( 120 ) of the front part ( 20 ) comprises an inside surface ( 122 ) and an outside surface ( 121 ) and the bottom portion ( 130 ) of the rear part ( 30 ) comprises an inside surface ( 132 ) and an outside surface ( 131 ), wherein the inside surface ( 122 ) of the bottom portion ( 120 ) of the front part ( 20 ) is glued to the rear part ( 30 ).

5. The receptacle ( 10 ) as claimed in claim 1 , characterized in that at least one side folding ( 3 ) extends between the front part ( 20 ) and the rear part ( 30 ).

6. The receptacle ( 10 ) as claimed in claim 1 , characterized in that the edge ( 2 ) of the opening ( 1 ) is formed at least in part by a front part edge ( 23 ) of the front part ( 20 ) and a rear part edge ( 33 ) of the rear part ( 30 ), wherein the front part edge ( 23 ) and the rear part edge ( 33 ) are at one height.

7. A receptacle ( 10 ), comprising a flexible bag ( 10 ) made of paper, having a front part ( 20 ), a rear part ( 30 ) and a bottom ( 50 ) which is closed by a bottom unit, and having an opening ( 1 ) which is located opposite the bottom ( 50 ), wherein the bottom unit comprises a bottom portion ( 120 ) of the front part ( 20 ) and a bottom portion ( 130 ) of the rear part ( 30 ), the bottom portion ( 130 ) of the rear part ( 30 ) is realized in a shortened manner in relation to the bottom portion ( 120 ) of the front part ( 20 ) such that the bottom portion ( 120 ) of the front part ( 20 ) is fastened directly on the rear part ( 30 ) as a result of turning the bottom unit ( 100 ) along a fold line ( 101 ), the opening ( 1 ) is formed by a peripheral edge ( 2 ) which extends at a height of the front part ( 20 ) and of the rear part ( 30 ) and which is frayed at least in part, as a result of which the risk of injury on the edge ( 2 ) is reduced, the edge ( 2 ) is frayed in a manner of both a perforation defined by a weakening on the paper without a cut through the paper and being torn off along the perforation;
wherein a handle opening ( 4 ) is realized by a laser on the front part ( 20 ) and on the rear part ( 30 );
wherein in a region of the handle opening ( 4 ) an inside ( 22 ) of the front part ( 20 ) and an inside ( 32 ) of the rear part ( 30 ) comprise a reinforcement strip ( 5 );
wherein the reinforcement strip ( 5 ) is at least partially realized by a laser.
