Abstract
Abstract A plastic bag to be carried in the hand and a method for manufacturing the plastic bag are disclosed. The plastic bag comprises a top part, a jacket part and a bottom part. The top part is provided with a carrying aperture or the like and the bottom part is provided with a filling valve or the like by which the plastic bag can be filled with bulk material. The top part of the plastic bag is formed by a transverse seam and a reinforcing patch attached to one side of the upper end of the bag whereby the top part includes three material plies. A reinforcing patch can be attached to both sides of the upper end of the bag so that the top part is constituted by four plies. In the case where the plastic bag is intended for carrying larger quantities of bulk material, the top part of the plastic bag is formed by at least one fold formed at the upper end of the bag to define a fold portion and the reinforcing patch joins the folded top portion to the jacket part and at the same time overlies at least a part of the transverse seam, the top part thus including at least five thicknesses of material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
206 words
In a hand carry bag constructed of a pair of adjacent plies of plastic material forming a two-ply main course, said bag including a top part, and a bottom part, and an intermediate jacket part, said top part having a carrying aperture formed therein, and wherein a seam joining said adjacent plies along narrow opposed regions thereof extends transversely across said bag to close said top part, the improvement comprising: said top part includes a first portion of said two-ply main course situated above said seam and which has a first pair of mutually adjacent plies and at least one fold portion constituting a second portion of said two-ply main course situated above said seam and which has a second pair of mutually adjacent plies, said fold portion being folded from said two-ply main course to overlie said first portion of said two-ply main course; a reinforcing patch having respective regions which at least partially overlie and are attached to said fold portion of said top part and said jacket part to join the same to each other, said reinforcing patch at the same time overlying and being attached to at least a part of said transverse seam to reinforce the same and improve its strength.
Claim 2
Dependent Claim
206 words
In a hand carry bag constructed of a pair of adjacent plies of plastic material forming a two-ply main course, said bag including a top part, and a bottom part, and an intermediate jacket part, said top part having a carrying aperture formed therein, and wherein a seam joining said adjacent plies along narrow opposed regions thereof extends transversely across said bag to close said top part, the improvement comprising: said top part includes a first portion of said two-ply main course situated above said seam and which has a first pair of mutually adjacent plies and at least one fold portion constituting a second portion of said two-ply main course situated above said seam and which has a second pair of mutually adjacent plies, said fold portion being folded from said two-ply main course to overlie said first portion of said two-ply main course; a reinforcing patch having respective regions which at least partially overlie and are attached to said fold portion of said top part and said jacket part to join the same to each other, said reinforcing patch at the same time overlying and being attached to at least a part of said transverse seam to reinforce the same and improve its strength.
Claim 3
Dependent Claim
21 words
The combination of claim 1 wherein said reinforcing patch is attached to one side of said top part of said bag.
Claim 4
Dependent Claim
23 words
The combination of claim 2 wherein a second reinforcing patch is attached to the other side of said top part of said bag.
Claim 5
Dependent Claim
55 words
The combination of claim 1 wherein the bag is formed of an initially flat blank having a substantially transverse upper edge; said seam spaced below and extending substantially parallel to said upper blank edge; and said fold portion terminating at said transverse upper blank edge which is situated above and proximate to said transverse seam.
Claim 6
Dependent Claim
28 words
The combination of claim 4 wherein a reinforcing patch is attached to the other side of said top part whereby said top part includes at least six plies.
Claim 7
Dependent Claim
31 words
The combination of claim 1, wherein said reinforcing patch constitutes the only other means of interconnection between said first and fold portions, in addition to the fold between these two portions.
Claim 8
Independent Claim
248 words
A method of manufacturing a hand carry bag from a blank having a substantially transversely extending upper edge and a pair of plies of plastic material forming a two-ply main course, the bag including a top part, a bottom part and an intermediate jacket part, said top part having a carrying aperture formed therein, said bottom part being provided with filling means for filling the bag with bulk goods, comprising the steps of: forming a transversely extending seam joining opposed narrow regions of the two plies of the blank at an upper part of said blank and spaced from the upper blank edge to define a first portion of said two-ply main course situated above said seam and which has a first pair of mutually adjacent plies; folding said two-ply main course to form a second fold portion of said two-ply main course situated above said seam and overlying said first portion of said two-ply main course, said second fold portion having a second pair of mutually adjacent plies, the fold portion terminating at the transverse upper blank edge which is situated proximate to and above said transverse seam; and attaching a reinforcing patch such that respective regions thereof at least partially overlie and are attached to the fold portion of the top part and the jacket part to join the same to each other and at the same time so that the reinforcing patch overlies and is attached to at least a part of the transverse seam.
Claim 9
Independent Claim
248 words
A method of manufacturing a hand carry bag from a blank having a substantially transversely extending upper edge and a pair of plies of plastic material forming a two-ply main course, the bag including a top part, a bottom part and an intermediate jacket part, said top part having a carrying aperture formed therein, said bottom part being provided with filling means for filling the bag with bulk goods, comprising the steps of: forming a transversely extending seam joining opposed narrow regions of the two plies of the blank at an upper part of said blank and spaced from the upper blank edge to define a first portion of said two-ply main course situated above said seam and which has a first pair of mutually adjacent plies; folding said two-ply main course to form a second fold portion of said two-ply main course situated above said seam and overlying said first portion of said two-ply main course, said second fold portion having a second pair of mutually adjacent plies, the fold portion terminating at the transverse upper blank edge which is situated proximate to and above said transverse seam; and attaching a reinforcing patch such that respective regions thereof at least partially overlie and are attached to the fold portion of the top part and the jacket part to join the same to each other and at the same time so that the reinforcing patch overlies and is attached to at least a part of the transverse seam.
Claim 10
Dependent Claim
19 words
The method of claim 7 wherein the reinforcing patch is attached only on one side of said top part.
Claim 11
Dependent Claim
27 words
The method of claim 7 comprising the additional step of attaching a second reinforcing patch to a side of the top part opposite the first reinforcing patch.
Claim 12
Dependent Claim
17 words
The method of claim 7 wherein said two-ply main course is folded after forming said transverse seam.
Claim 13
Dependent Claim
28 words
The method of claim 7 wherein said reinforcing patch is attached to at least a part of the transverse seam prior to said two-ply main course being folded.
Claim 14
Dependent Claim
18 words
The method of claim 7, wherein said reinforcing patch is attached after said two-ply main course is folded.
