Abstract
A standup bags made of a flexible material and methods of producing these standup bags. In particular, the standup bags have at least one substantially flat surface which is free of seams and folds. When the bag is filled with a flowable substance, the pressure exerted by the fluid upon the flat surfaces allows the bag to be self-standing. Additionally, the standup includes at least one contour structure that defines the geometry of the bag and also contributes to the standup bag's ability to be self-standing when even partially filled with a flowable substance.
Claims14
A standup bag, comprising:
- an enclosure defined by a front wall, a rear wall, a first side wall, a second side wall opposing the first side wall, a top wall and a bottom wall,
- the first side wall further comprising:
- a first substantially longitudinal seal having a first end and a second end;
- an upwardly concave seal extending from the first end of the first substantially longitudinal seal, with a first component thereof terminating proximate a corner region formed by the intersection of the first side wall with the top wall and front wall, and with a second component thereof terminating proximate a corner region formed by the intersection of the sida wall with the top wall and the rear wall;
- and
- a downwardly concave seal extending from the second end of the first substantially longitudinal seal, with a first component thereof terminating proximate a corner region formed by the intersection of the first side wall with the bottom wall and the front wall, and with the second component thereof terminating proximate a corner region formed by the intersection of the first side wall with the bottom wall and the rear wall;
- and
- the second side wall further comprising:
- a second substantlally longitudinal seal having a first end and a second end;
- an upwardly concave seal extending from the first end of the second substantially longitudinal seal, with a first component thereof terminating proximate a corner region formed by the intersection of the second side wall with the top wall and front wall, and with a second component thereof terminating proximate a corner region formed by the intersectio of the second side wall with the top wall and the rear wall;
- and
- a downwardly concave seal extending from the second end of the second substantially longitudinal seal, with a first component thereof terminating proximate a corner region formed by the intersection of the second side wall with the bottom wall and the front wall, and with second component thereof terminating proximate a corner region formed by the intersection of the second side wall with the bottom wall and the rear wall.
