Abstract
A bag formed of a sheet material adapted to be filled with contents and opened at the top for taking out the contents. The bag has fused joints along the lateral edges thereof. A plastically deformable wire-like member is attached inside the fused joints over a length from the output opening side portion to the body portion.
Claims12
A bag formed of a sheet material, comprising:
- a plastically deformable wire-like member attached exclusively along a lateral edge of said bag, the lateral edge having a hem seal formed by heat sealing, the wire-like member being disposed inside a fused joint of a folded back hem seal of said bag with a non-fused portion left between the wire-like member and a surrounding fused portion of the hem seal,
- wherein said vertical wire-like member is disposed along the lateral edge inside said folded back hem seal joint such that the folded back hem seal joint is positioned at a top end, at a bottom end, and on at least one side of the vertical wire-like member so as to leave a space from a fused portion of said joint and is disposed exclusively along an upper portion of the hem seal joint of said bag.
A gusset bag, comprising:
- a pair of main faces and a pair of inward folding side faces being adapted to be opened at a top portion of said gusset bag for taking out contents of the gusset bag while self-standing;
- a deformable vertical wire-like member vertically attached along each lateral edge of said gusset bag that is an intersection of adjacent main and side faces over a length from an output opening side portion to a body portion of the gusset bag and is disposed along an upper portion of said gusset bag such that the vertical wire-like member does not extend to a top edge of the gusset bag;
- and
- a lateral wire-like member laterally attached to each of the side faces to substantially form the shape of an inverted angular “U” together with a pair of the vertical wire-like members when the pair of main faces is not folded and the pair of side faces is folded inwardly.

A bag formed of a sheet material, comprising:
- a plastically deformable wire-like member attached exclusively along a lateral edge of said bag, the wire-like member being disposed inside a fused joint of a folded back hem seal of said bag formed along the lateral edge such that the wire-like member does not extend to a top edge of the bag;
- and
- a rectangular projection which extends along side faces of said bag for maintaining a rectangular shape of said bag upon being open,
- wherein the wire-like member is disposed exclusively along an upper portion of the hem seal joint of the bag.

A bag formed of a sheet material, comprising:
- a plastically deformable wire-like member attached exclusively along a lateral edge of said bag, the lateral edge having a hem seal formed by heat sealing, the wire-like member being disposed inside a fused joint of a folded back hem seal of said bag with a non-fused portion left between the wire-like member and a surrounding fused portion of the hem seal, wherein said wire-like member is disposed along the lateral edge inside said folded back hem seal joint such that the folded back hem seal joint is positioned at a top end, at a bottom end, and on at least one side of the wire-like member so as to leave a space from a fused portion of said joint and is disposed exclusively along an upper portion of the hem seal joint of said bag;
- and
- a tubular holder for holding said wire-like member wherein a portion free of said wire-like member of said bag configured for forming an open space of said bag is provided between a top edge of said bag around an opening of said bag and an upper open end of said tubular holder.
