Abstract
Abstract A rigid, non-removable hollow cylindrical insert is located in the end portion of a deformable plastic tube. The end portion of the tube is situated between thin film layers with the insert aligned with an edge to be sealed. The assembly is placed between the mating pressure dies to be welded. In a single operation, the edges of the layers are sealed to form a pouch as the tube end portion is welded to the layers along the seam at the top of the pouch. The insert supports the tube end portion in a non-deformed state during welding. This permits an effective weld to be obtained with tubes of various structures and, particularly, very soft tubes such as one with thin walls composed of polyvinylchloride.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
98 words
A tube and pouch combination, said tube comprising a relatively deformable hollow body having an inner diameter and an end portion, said pouch comprising first and second walls sealed along an edge except at an opening into which said end portion is welded and a hollow tubular insert non-removably mounted within said end portion in alignment with said edge and having an outer diameter substantially equal to the inner diameter of said member, said insert being relatively rigid and supporting said end portion in a relatively non-deformed condition as said end portion is welded between said pouch walls.
Claim 2
Dependent Claim
98 words
A tube and pouch combination, said tube comprising a relatively deformable hollow body having an inner diameter and an end portion, said pouch comprising first and second walls sealed along an edge except at an opening into which said end portion is welded and a hollow tubular insert non-removably mounted within said end portion in alignment with said edge and having an outer diameter substantially equal to the inner diameter of said member, said insert being relatively rigid and supporting said end portion in a relatively non-deformed condition as said end portion is welded between said pouch walls.
Claim 3
Dependent Claim
20 words
The combination of Claim 1, wherein said insert comprises an inclined end to facilitate insertion thereof into said end portion.
Claim 4
Dependent Claim
21 words
The combination of Claim 1, wherein the walls of said tube are in the range of .5 to 1.0 mm. thick.
Claim 5
Dependent Claim
12 words
The combination of Claim 1, wherein said body is composed of polyvinylchloride.
Claim 6
Dependent Claim
12 words
The combination of Claim 1, wherein said pouch walls are-composed of polyvinylchloride.
Claim 7
Dependent Claim
12 words
The combination of Claim 1, wherein said insert is composed of polyethylene
Claim 8
Dependent Claim
14 words
The combination of Claim 1, wherein . said insert is approximately one inch long.
Claim 9
Independent Claim
137 words
A method for joining the end portion of a relatively deformable tube to a pouch or the like having first and second walls seamed along a peripheral edge portion in a welding tool of the type having mating pressure dies, the method comprising the steps of: (a) inserting, into said end portion, a non-remoyable, relatively rigid, hollow tubular member; (b) locating said end portion between the walls of the pouch with said member aligned with the peripheral edge portions thereof; (c) placing the tube-pouch assembly between the dies; and - (d) applying pressure and energy through the dies such that the peripheral edge portion of the walls of the pouch are welded together and to the exterior surface of the end portion of the tube, as the member supports the end portion in a relatively non-deformed state.
Claim 10
Independent Claim
137 words
A method for joining the end portion of a relatively deformable tube to a pouch or the like having first and second walls seamed along a peripheral edge portion in a welding tool of the type having mating pressure dies, the method comprising the steps of: (a) inserting, into said end portion, a non-remoyable, relatively rigid, hollow tubular member; (b) locating said end portion between the walls of the pouch with said member aligned with the peripheral edge portions thereof; (c) placing the tube-pouch assembly between the dies; and - (d) applying pressure and energy through the dies such that the peripheral edge portion of the walls of the pouch are welded together and to the exterior surface of the end portion of the tube, as the member supports the end portion in a relatively non-deformed state.
Claim 11
Dependent Claim
35 words
The method of Claim 8, wherein the step of inserting comprises.the steps of forming an inclined leading edge on one end of said member; and causing said leading edge to be received in the member.
