Abstract
Abstract There is disclosed a method for attaching a polyethylene sleeve label to a polyethylene bottle, the label having on the outer surface thereof means for absorbing heat in local, discrete areas of the label at a rate greater than that of other areas of the label; and means for welding the label to the body at the junction of the outer surface of the body and the inner surface of the label, adjacent the local heat-absorbing areas.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
A method for attaching a polyethylene sleeve label to a polyethylene bottle, the bottle having a neck, a body and a bottom; the method comprising the steps of: a. supporting said bottle with the label located around the body of the bottle, said label including means on the label for absorbing heat in local discrete areas at a rate greater than other areas of the label; and b. welding the label to the bottle, with radiant heat without an adhesive, adjacent the heat-absorbing areas of the label at the junction of the outer surface of the body of said bottle and inner surface of said label to thereby prevent loss of the label.
Claim 2
Independent Claim
113 words
A method for attaching a polyethylene sleeve label to a polyethylene bottle, the bottle having a neck, a body and a bottom; the method comprising the steps of: a. supporting said bottle with the label located around the body of the bottle, said label including means on the label for absorbing heat in local discrete areas at a rate greater than other areas of the label; and b. welding the label to the bottle, with radiant heat without an adhesive, adjacent the heat-absorbing areas of the label at the junction of the outer surface of the body of said bottle and inner surface of said label to thereby prevent loss of the label.
Claim 3
Dependent Claim
50 words
A method as defined in claim 1 in which the welding step includes concentrating heat on said heat-absorbing areas of the label with heating means disposed on opposite sides of said bottle and label so as to provide non-continuous welded areas which are disposed on opposite sides of the bottle.
Claim 4
Dependent Claim
35 words
The method of claim 1 wherein said means on said label are at least disposed on opposite sides thereof and the label is welded to the bottle substantially solely on opposite sides of the bottle.
Claim 5
Independent Claim
71 words
A method for securely attaching a polyethylene sleeve label to a polyethylene bottle comprising, providing a polyethylene bottle carrying said label, said label having an area capable of absorbing heat at a rate greater than another area of said label, and welding, with radiant heat without an adhesive, said label to said bottle by heating said greater heat absorbing area so as to prevent loss of said label from said bottle.
Claim 6
Independent Claim
71 words
A method for securely attaching a polyethylene sleeve label to a polyethylene bottle comprising, providing a polyethylene bottle carrying said label, said label having an area capable of absorbing heat at a rate greater than another area of said label, and welding, with radiant heat without an adhesive, said label to said bottle by heating said greater heat absorbing area so as to prevent loss of said label from said bottle.
Claim 7
Dependent Claim
27 words
The method of claim 4 wherein said step of welding is effected while said bottle carrying said label is moved by a conveyor in an upright position.
Claim 8
Dependent Claim
16 words
The method of claim 5 wherein said welding is effected to produce opposite, separate welded areas.
