Abstract
Abstract A carry-bag includes two wall sheets (34,36) joined or coherent to define a bag portion, and the respective top portions of the wall sheets are provided with gripping and carrying openings. In order to provide a strong, easy to use, and relatively tight closing to the interior of the bag portion, the top portion of a first wall sheet (34) has been folded inwardly and attached to define an insertion pocket (24), and a gripping opening is provided in the pocket. A top portion of the other wall sheet (36) is shaped as an insertion tongue (32) which is also provided with a gripping opening (6) and is adapted to be received in the interior of the pocket (24) so that the two gripping openings are at least partially coextensive. In particular, if a carrying stick has been inserted in a passage (8) along the top edge of the insertion tongue, there is provided a strong carrying means which also closes effectively to the interior of the bag portion, since the top edge of the tongue will be drawn against the bottom in the pocket, when carrying the bag.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
257 words
A carrier bag comprising: a first wall sheet; a second wall sheet joining said first wall sheet along two opposed side edges and along a bottom edge so as to define a bag portion; a top portion of said first wall sheet being folded upon itself to define an insertion pocket having an entry edge located at an inner side of said first wall sheet, when said bag is in an open condition and said top portion of said first wall sheet includes a cut defining a first gripping opening and a closing flap; a top portion of said second wall sheet defining an insertion flap adapted for introduction into the interior of said insertion pocket; a second gripping opening defined by said insertion flap adapted for introduction into the interior of said insertion pocket so that said first gripping opening and said second gripping opening are at least partially coextensive when said insertion flap is received in said insertion pocket; said closing flap having a free front edge, the size and location of said closing flap being so adapted that said closing flap extends through said first gripping opening and said second gripping opening when said insertion flap is received in said insertion pocket to close access to the interior of said bag portion at said first gripping opening and said second gripping opening; and means for removably attaching said free front edge of said closing flap to the outer side of said second wall sheet when said insertion flap is received in said insertion pocket.
Claim 2
Dependent Claim
257 words
A carrier bag comprising: a first wall sheet; a second wall sheet joining said first wall sheet along two opposed side edges and along a bottom edge so as to define a bag portion; a top portion of said first wall sheet being folded upon itself to define an insertion pocket having an entry edge located at an inner side of said first wall sheet, when said bag is in an open condition and said top portion of said first wall sheet includes a cut defining a first gripping opening and a closing flap; a top portion of said second wall sheet defining an insertion flap adapted for introduction into the interior of said insertion pocket; a second gripping opening defined by said insertion flap adapted for introduction into the interior of said insertion pocket so that said first gripping opening and said second gripping opening are at least partially coextensive when said insertion flap is received in said insertion pocket; said closing flap having a free front edge, the size and location of said closing flap being so adapted that said closing flap extends through said first gripping opening and said second gripping opening when said insertion flap is received in said insertion pocket to close access to the interior of said bag portion at said first gripping opening and said second gripping opening; and means for removably attaching said free front edge of said closing flap to the outer side of said second wall sheet when said insertion flap is received in said insertion pocket.
Claim 3
Dependent Claim
71 words
A carrier bag of claim 1, wherein said cut in said insertion pocket is a U-shaped cut provided in said first wall sheet before the formation of said insertion pocket by folding, a portion of said U-shaped cut extending along, but spaced from, a top edge of said unfolded first wall sheet, and wherein a portion of said first wall sheet cut free by said U-shaped cut forms said closing flap.
Claim 4
Dependent Claim
31 words
The carrier bag of claim 1, wherein a top edge of said insertion flap is provided with a passage adapted to receive a transverse carrying stick extending along said top edge.
Claim 5
Dependent Claim
33 words
The carrier bag of claim 1, wherein said top portions of said first and said second wall sheets have been doubled by folding before forming said insertion flap and said insertion pocket respectively.
Claim 6
Dependent Claim
55 words
The carrier bag of claim 1, wherein side edge seals of said first and said second sheets are extended to a top edge of said bag, thereby sealing opposite sides of said insertion pocket, whereas the corresponding side edges of said insertion flap are cut away and kept free of the respective side edge seals.
Claim 7
Dependent Claim
28 words
The carrier bag of claim 1, wherein said first wall sheet and said second wall sheet each includes at least one flexible cover layer and a compressible layer.
Claim 8
Dependent Claim
29 words
The carrier bag of claim 6, wherein said compressible layer is formed of a material capable of substantially recovering its initial thickness, when the material is relieved after compression.
Claim 9
Dependent Claim
20 words
The carrier bag of claim 7, wherein said material is a heat insulating material enclosed between two flexible cover layers.
