Abstract: 1. A stand up bag of a heat-sealable or weldable plastic film for receiving liquid and/or paste-like material, comprising two side walls (2, 3) connected to each other at the longitudinal edges thereof, a foldable bottom member which is positioned between said side walls (2, 3) and serves as a self-standing bottom (10) being arranged at the lower end of said stand up bag between lower transverse edges (8, 9), and a foldable cover member being positioned at the upper end of said stand up bag between said side walls (2, 3), and comprising a removal opening (12) between an upper transverse edge (13, 20) of a first side wall (2) and the associated cover member edge (21, 22), a closure element (20) being inserted into said removal opening (12), characterized in that said stand up bag is provided in said first side wall (2) in an area below said closure element (20) with means (33) for stabilizing and retaining said closure element (20) in a forwardly bent position. 2. The stand up bag according to claim 1, characterized in that said upper cover member is provided in an area below said closure element (20) with means (34) for stabilizing and retaining said closure element in an upright position. 3. The stand up bag according to claims 1 or 2, characterized in that said means for stabilizing and retaining said closure element is formed from at least one embossment (33, 34). 4. The stand up bag according to claims 1 and 3, characterized in that said embossment extends from two sides towards the central longitudinal axis (A) of said first side wall (2) as a line embossment. 5. The stand up bag according to at least one of the preceding claims, characterized in that said embossment (33) is a semi-oval line embossment. 6. The stand up bag according to at least one of the preceding claims, characterized in that said embossment (33) is a triangular line embossment. 7. The stand up bag according to at least one of the preceding claims, characterized in that that said embossment (33, 34) is directed from the inside to the outside. 8. The stand up bag according to at least one of the preceding claims, characterized in that said means for stabilizing and retaining said closure element are arranged in the forwardly bent position in the upper third of said first side wall (2). 9. The stand up bag according to claim 1, characterized in that said removal opening (12) is formed between a side wall tab (14) formed on a side wall (2) and projecting beyond a transverse edge (13) of said side wall (2), and a matching cover member tab (15) formed on said cover member (11), said tabs being interconnected along the longitudinal edges (16, 17, 18, 19) thereof. 10. The stand up bag, in particular according to claim 1 or 9, characterized in that said cover member (11) is connected to the respective side wall (3, 2) via seal seams (30) which extend from both longitudinal edges (4, 7) obliquely towards said removal opening (12) of said first side wall or obliquely towards the upper transverse edge of said second side wall; said sloped seal seams (30) being outer seams at the same time. 11. The stand up bag according to at least one of the preceding claims, characterized in that said side walls (2, 3) are provided with longitudinal embossments (21) which extend in spaced-apart relationship between said transverse edges (6, 7, 4, 5) and are oriented to the outside. 12. The stand up bag according to at least one of the preceding claims, characterized in that the length (h1) of said first side wall (2) is greater than the length (h2) of said second side wall (3), so that said removal opening of said first side wall comes to rest above the upper transverse edge (31) of said second side wall (3). 13. The stand up bag according to at least one of the preceding claims, characterized in that said cover member is made integral with said second side wall (3).
