Abstract

Abstract A flat mass-produced bag, preferably of plastic, of a rectangular shape made of two layers and having a mouth at one side adapted to be closed by draw strings which are slidable in hems formed adjacent to the mouth by folding over the free ends of both layers and securing them to the layers. The draw strings have a length greater than the width of the bag and the ends of each pair of corresponding strings are knotted together outside of each lateral side of the bag. When the two knotted pairs of strings are pulled in opposite directions, the mouth of the bag will be drawn closed toward its center.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 190 words
A drawstring bag comprising two opposite walls connected to each other along all except one side of said bag to provide at said one side an opening forming the mouth of said bag, each of said two walls having at said mouth a portion folded outwardly toward the respective wall so as to form a hem having a free edge substantially parallel to the outer edge of said mouth, and each of said folded portions being connected along said free edge and along a line between said edge of said mouth and said free edge to the adjacent unfolded portion of the respective wall so as to form two substantially parallel channels in each hem, each defined at one side by said folded and at the opposite side, by said unfolded portion of the respective wall; a string extending through each of said channels, each of said strings in one hem being disposed opposite to one of said strings in the other hem and together forming a pair; and means for connecting the corresponding ends of the strings of each pair at points outside of said hems to each other.
Claim 2
Dependent Claim 190 words
A drawstring bag comprising two opposite walls connected to each other along all except one side of said bag to provide at said one side an opening forming the mouth of said bag, each of said two walls having at said mouth a portion folded outwardly toward the respective wall so as to form a hem having a free edge substantially parallel to the outer edge of said mouth, and each of said folded portions being connected along said free edge and along a line between said edge of said mouth and said free edge to the adjacent unfolded portion of the respective wall so as to form two substantially parallel channels in each hem, each defined at one side by said folded and at the opposite side, by said unfolded portion of the respective wall; a string extending through each of said channels, each of said strings in one hem being disposed opposite to one of said strings in the other hem and together forming a pair; and means for connecting the corresponding ends of the strings of each pair at points outside of said hems to each other.
Claim 3
Dependent Claim 45 words
A bag as defined in claim 1, in which said strings have such a length and said connecting means are located in such positions that at least one of said connecting means on each of said pairs of strings is spaced considerably from said bag.
Claim 4
Dependent Claim 29 words
A bag as defined in claim 1, in which said connecting means are formed by knots tying said corresponding ends of each pair of said strings to each other.
Claim 5
Dependent Claim 46 words
A bag as defined in claim 1 in combination with means forming welds for connecting said folded hem parts of said bag walls to said adjacent unfolded parts of said walls along said two lines extending substantially parallel to the folded outer edge of said mouth.
Claim 6
Dependent Claim 79 words
A bag as defined in claim 4, in which said weld means which are disposed on each of said hems along a line which is spaced at a greater distance from said folded mouth edge form a continuous line of weld, while said weld means disposed on each of said hems along a line which is spaced at a smaller distance from said folded mouth edge and located between said two parallel channels form an intermittent line of weld.
Claim 7
Dependent Claim 62 words
A bag as defined in claim 1, in which said two walls of said bag consist of a single sheet and are connected to each other by folding said sheet at the side of said bag opposite to the side forming said mouth and by Welds along the lateral sides of said bag up to said hems adjacent to said bag mouth.
Claim 8
Dependent Claim 19 words
A bag as defined in claim 1, in which said two walls of said bag consist of sheet plastic.
