Abstract

Abstract By first folding inwardly one closed end of a tube made of a synthetic resin to form opposing folded end portions, thereafter thermally bonding or adhesively attaching a thick piece of plate made of a synthetic resin to each of said end portions either on the inside or outside of the fold or between the two sheets of the tube constituting the fold, then forming a grip hole in each of the attached two pieces of plate (said grip hole may be formed in advance), thereafter packing desired contents in said tube from the open end on the other side of the tube, and then sealing this open end, there is provided a bag having a pair of grip handles which are retained on the bag after the portion of the tube material located between the folded two end portions is cut apart to dispense the contents.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 135 words
A bag made of a tube of synthetic resin, and comprising one closed end, said one end being folded of the opposing sheets of the tube to form opposing two folded end portions which are provided with a thermal bonding of broad width along the whole portion of foremost ends thereof; a pair of grip handle members made of synthetic resin thicker than that of the bag, each having a hole for insertion of fingers and being of a width almost equal to that of the bag, said grip handle members being securely attached by thermal bonding of broad width to almost the whole width of said opposing two folded end portions; and an open end from which desired contents are packed into the bag and which is closed by thermal bonding of broad width.
Claim 2
Dependent Claim 135 words
A bag made of a tube of synthetic resin, and comprising one closed end, said one end being folded of the opposing sheets of the tube to form opposing two folded end portions which are provided with a thermal bonding of broad width along the whole portion of foremost ends thereof; a pair of grip handle members made of synthetic resin thicker than that of the bag, each having a hole for insertion of fingers and being of a width almost equal to that of the bag, said grip handle members being securely attached by thermal bonding of broad width to almost the whole width of said opposing two folded end portions; and an open end from which desired contents are packed into the bag and which is closed by thermal bonding of broad width.
Claim 3
Dependent Claim 61 words
A bag according to claim 1, in which said grip handle members are securely attached along the whole root portion almost equal to the diameter of the bag opening to the opposing two folded end portions, respectively, on the outer sides thereof, and said handle members are subjected to auxiliary welding at appropriate sites by relying on the spot welding technique.
Claim 4
Dependent Claim 56 words
A bag according to claim 1, in which said grip handle members are securely attached along the whole one sides thereof except the grip holes to the opposing two folded end portions, respectively, on the inner sides thereof, and thermal bonding is provided between said folded end portions and said handle members around said grip holes.
Claim 5
Dependent Claim 102 words
A baG according to claim 1, in which said grip handle members are securely attached to the opposing two folded end portions, respectively, the whole portion of each of said handle members being sandwiched between the opposing two sheets of the tube constituting one fold; the peripheral edges of each of the grip handle sections being produced by cutting the bilateral edge portions of said folded end portions which are subjected to thermal bonding; and thermal bonding is provided between the respective sheets of said folded end portions and said handle members around grip holes formed through each of said handle sections.
