Bag construction with auxiliary flap

Claim 2

A flexible bag for carrying articles which is of the flat-bottom type and which includes front, back, gussetted side and bottom panels with the bottom panel movable from a closed position to an open position transverse to said back, front and side panels, and which the back panel includes an overlapping generally centrally positioned seam and said bag further including a removable section: (a) extending from the center seam toward an adjacent side panel; (b) being defined by (i) a section-forming perforation which is generally parallel to the seam and extending between the top and bottom of the bag and (ii) an edge generally parallel to the junction of the back and bottom panels and intersecting the section forming perforation; (c) wherein said perforation is the only section-forming perforation; and (d) having an extension which is integral with the removable section which extension cooperates in forming the bottom panel.

Claim 3

A unitary blank formed from a web for use in forming a flexible bag, which blank includes a plurality of panel defining score and fold lines which define back, front, said and flat bottom panels and wherein the improvement comprises said back panel having an inner portion and an outer portion, wherein the outer portion is wider than the inner portion, said portions adapted to overlap and be adhered together along a generally centrally positioned back seam, said outer portion including a removable section having a perforation constructed to be positioned generally parallel to the back seam and said removable section being less than about one-half as wide as the back pane, being formed so as to overlap the inner part of the back and extending to the edge formed by the inner portion of the back and the adjacent side panel so as to form an off-center positioned removable section and said removable section includes an extension which cooperates in forming said bottom panel and said extension and removable section having a common fold line for defining an edge thereof and said fold line being transverse to the said perforation and said perforation being the only removable-section defining perforation.

Claim 4

A unitary blank formed from a web for use in forming a flexible bag, which blank includes a plurality of panel defining score and fold lines which define back, front, said and flat bottom panels and wherein the improvement comprises said back panel having an inner portion and an outer portion, wherein the outer portion is wider than the inner portion, said portions adapted to overlap and be adhered together along a generally centrally positioned back seam, said outer portion including a removable section having a perforation constructed to be positioned generally parallel to the back seam and said removable section being less than about one-half as wide as the back pane, being formed so as to overlap the inner part of the back and extending to the edge formed by the inner portion of the back and the adjacent side panel so as to form an off-center positioned removable section and said removable section includes an extension which cooperates in forming said bottom panel and said extension and removable section having a common fold line for defining an edge thereof and said fold line being transverse to the said perforation and said perforation being the only removable-section defining perforation.

Claim 5

A flexible bag for carrying articles which is of the V- or pinch-bottom type and which include front, back and side panels which cooperate to form a bottom movable from a closed position to an open position and which the back panel includes an overlapping generally centrally positioned seam and said bag further including a removable section: a) extending from the center seam toward an adjacent side panel; (b) being defined by (i) a section-forming perforation which is generally parallel to the seam and extending between the top and bottom of the bag and (ii) an edge generally parallel to the junction of the back panel and bottom and intersecting the section-forming perforation; (c) wherein said perforation is the only section-forming perforation; and (d) having an extension which is integral with the removable section which extension cooperates in forming the bottom.

Claim 6

A flexible bag for carrying articles which is of the V- or pinch-bottom type and which include front, back and side panels which cooperate to form a bottom movable from a closed position to an open position and which the back panel includes an overlapping generally centrally positioned seam and said bag further including a removable section: a) extending from the center seam toward an adjacent side panel; (b) being defined by (i) a section-forming perforation which is generally parallel to the seam and extending between the top and bottom of the bag and (ii) an edge generally parallel to the junction of the back panel and bottom and intersecting the section-forming perforation; (c) wherein said perforation is the only section-forming perforation; and (d) having an extension which is integral with the removable section which extension cooperates in forming the bottom.

Claim 7

A unitary blank formed from a web for use in forming a flexible V-shaped or pinch-bottom bag type, which blank includes a plurality of score and fold lines which define back, front and side panels and a bottom and wherein the improvement comprises said back panel having an inner portion and an outer portion, wherein the outer portion is wider than the inner portion, said portions adapted to overlap and be adhered together along a generally centrally positioned back seam, said outer portion including a removable section having a perforation constructed to be positioned generally parallel to the back seam and said removable section being less than about one-half as wide as the back panel, being formed so as to overlap the inner part of the back and extending to the back edge formed by the inner portion of the back and the adjacent side panels so as to form an off-center positioned removable section and said removable section includes an extension which cooperates in forming said bottom and said extension and removable section having a common fold line for defining an edge thereof and said fold line being transverse to the said perforation and said perforation being the only removable section-defining perforation.

Claim 8

A unitary blank formed from a web for use in forming a flexible V-shaped or pinch-bottom bag type, which blank includes a plurality of score and fold lines which define back, front and side panels and a bottom and wherein the improvement comprises said back panel having an inner portion and an outer portion, wherein the outer portion is wider than the inner portion, said portions adapted to overlap and be adhered together along a generally centrally positioned back seam, said outer portion including a removable section having a perforation constructed to be positioned generally parallel to the back seam and said removable section being less than about one-half as wide as the back panel, being formed so as to overlap the inner part of the back and extending to the back edge formed by the inner portion of the back and the adjacent side panels so as to form an off-center positioned removable section and said removable section includes an extension which cooperates in forming said bottom and said extension and removable section having a common fold line for defining an edge thereof and said fold line being transverse to the said perforation and said perforation being the only removable section-defining perforation.
