Abstract
A foldable bag comprises a front sheet and a back sheet which are circumferentially joined to each other. The bag is disposed in a folded condition in which the bag has a reversed T-shape including a bottom and an upward portion extending upwardly from the bottom. In the folded condition of the bag, upward portion side edges are inwardly creased between the front sheet and the back sheet such that they face to each other. At the bottom, an inner bottom edge portion extends substantially within a plane of the upward portion and each of outer bottom edge portions extend substantially parallel above the inner bottom edge portion.
Claims11
A foldable bag, comprising
- a front sheet and a back sheet circumferentially joined to each other in an unfolded condition wherein in the unfolded condition the bag has a bottom edge and an opposite top edge, and opposite side edges extending between the top edge and the bottom edge, wherein the bottom edge includes an inner bottom edge portion and outer bottom edge portions located at opposite sides of the inner bottom edge portion and extending up to the respective side edges, and wherein the bottom edge and opposing side edges join the front sheet directly to the back sheet and to define a cavity for fluid, so that the entirety of the back sheet is directly overlying the front sheet throughout the cavity;
- and wherein in a folded condition in which the bag has a reversed T-shape including a bottom and an upward portion extending upwardly from the bottom, wherein
- in the folded condition of the bag at the upward portion the side edges are inwardly creased between the front sheet and the back sheet such that they face to each other, and at the bottom the inner bottom edge portion extends substantially within the plane of the upward portion and each of the outer bottom edge portions extend substantially parallel above the inner bottom edge portion
- whereupon filling of the bag in the folded condition returns the bag to the unfolded condition.
A foldable bag comprises a front sheet and a back sheet which are circumferentially joined to each other in an unfolded condition wherein the bag is disposed in a folded condition in which the bag has a reversed T-shape including a bottom and an upward portion extending upwardly from the bottom, and wherein in the folded condition of the bag, upward portion side edges are inwardly creased between the front sheet and the back sheet such that they face to each other, and wherein at the bottom, an inner bottom edge portion extends substantially within a plane of the upward portion and each of outer bottom edge portions extend substantially parallel above the inner bottom edge portion whereupon filling of the bag in the folded condition returns the bag to the unfolded condition.
A foldable bag comprises a front sheet and a back sheet which are circumferentially joined to each other in an unfolded condition wherein the bag is disposed in a folded condition wherein the bag includes a bottom edge and a top edge opposite to each other, and inwardly creased bag portions facing toward each other and extending between the bottom edge and the top edge, wherein each of the inwardly creased bag portions has an upper closed end located near the top edge and a lower closed end located near the bottom edge, wherein the upper closed end and the lower closed end are free ends, and wherein side edge portions are displaced from each other and located at a predetermined distance from the bottom edge at entrances of the inwardly creased portions away from each other whereupon filling of the bag in the folded condition returns the bag to the unfolded condition.
