Folding bag
A folded box has side walls and a base unit and/or a lid unit. At least one of the side walls has a convex curvature when the folded box is folded up. At least one supporting unit is connected to the inner wall of the convexly curved side wall and has a first adhesive tab and a second adhesive tab, which are connected to the inner wall and which are arranged spaced apart from each other in the direction of the curvature. Between the first and second adhesive tab there is a supporting tab, which is connected to the first and the second adhesive tab via a first and a second supporting tab fold, respectively. The length of the supporting tab corresponds to the distance between the first and the second adhesive tab. When the box is folded up, the supporting tab can be folded into the interior of the folded box or, folded up automatically into the interior of the folded box.
1. A folded box having side walls and a base unit and/or a lid unit, at least one of the side walls having a convex curvature when the folded box is folded up, the folded box further comprising
at least one supporting unit connected to an inner surface of the convexly curved side wall, the at least one supporting unit having
a first adhesive tab and a second adhesive tab connected to the inner surface of the convexly curved side wall and arranged spaced apart from each other in the direction of the curvature; and
a supporting tab between the first and second adhesive tab and positioned along the convexly curved sidewall, the supporting tab being connected to the first and the second adhesive tab via a first supporting tab fold and a second supporting tab fold, respectively, the length of the supporting tab corresponding to the distance between the first adhesive tab and the second adhesive tab, wherein, when the folded box is folded up, the supporting tab is adapted to be folded into the interior of the folded box or, when the folded box is folded up, the supporting tab is adapted to fold up automatically into the interior of the folded box.
2. The folded box as claimed in claim 1 , further comprising a plurality of supporting units arranged in the direction of the curvature.
3. The folded box as claimed in claim 1 , wherein the folded box has two convexly curved side walls which, when folded up, are opposite each other, so that the result is an oval or round cross-sectional shape, and opposite supporting units are arranged on the inside of the side walls.
4. The folded box as claimed in claim 1 , wherein the supporting tab has a convex curvature inward when folded up.
5. The folded box as claimed in claim 1 , wherein the supporting tab includes at least one further supporting tab fold, the at least one further supporting tab fold being parallel to the first supporting tab fold and the second supporting tab fold and being arranged centrally on the supporting tab.
6. The folded box as claimed in claim 1 , wherein the supporting tab comprises double walls.
7. The folded box as claimed in claim 1 , wherein the supporting tab is arranged underneath the base unit and/or above the lid unit.
8. The folded box as claimed in claim 1 , wherein the base unit and/or the lid unit is connected to the inner surface of the convexly curved side wall via a base fold and a lid fold, respectively, the base fold and lid fold being arranged substantially at the same height as an upper and a lower edge, respectively, of the folded-up supporting tab.
9. The folded box as claimed in claim 8 , wherein the base unit and the lid unit are provided with a base adhesive tab and a lid adhesive tab, respectively, the base adhesive tab and the lid adhesive tab being connected to the convexly curved side wall via a base adhesive tab fold and a lid adhesive tab fold, respectively, the base adhesive tab and the lid adhesive tab further adapted to be connected to the inner surface of the convexly curved side wall.
10. The folded box as claimed in claim 1 , wherein the first and second adhesive tabs of the supporting unit are integrally molded on a lower and/or upper front end edge of the convexly curved side wall via a first adhesive tab fold and a second adhesive tab fold, the folded box further comprising a slot between the convexly curved side wall and the supporting tab.
11. The folded box as claimed in claim 1 , wherein the supporting tab is reinforced by at least one reinforcing tab, the at least one reinforcing tab being connected to the supporting tab via a reinforcing tab fold, the reinforcing tab fold being parallel to the first adhesive tab fold and the second adhesive tab fold.
12. The folded box as claimed in claim 3 , wherein the base unit and/or the lid unit have an external circumferential contour which corresponds substantially to an inner circumferential contour, formed by the convexly curved side walls, of the folded box.
13. The folded box as claimed in claim 1 , wherein the base unit or the lid unit is double-walled.
14. The folded box as claimed in claim 1 , wherein the folded box is composed of board material or plastics material.
15. The folded box as claimed in claim 1 , wherein the folded box is formed from a one-piece blank.
16. The folded box as claimed in claim 1 , further comprising a slot between the supporting tab and the convexly curved side wall.
