Claim 1
Independent Claim
242 words
A packing tube, comprising: (a) a tubular body formed of a multi layered foil including a metallic barrier layer disposed between layers of synthetic material and having an inwardly directed peripheral rim; (b) a headpiece formed of synthetic material having a discharge opening, said headpiece including two superimposed portions, the lower portion completely covering the underside of the upper portion and formed of a non-permeable material, the outer diameter of said headpiece being less than the inner diameter of said tubular body, and said upper and lower portions forming an outer rim edge which is bevelled with respect to the central axis of the headpiece; and (c) a connecting element, disposed on said headpiece, including an upper and lower synthetic material layer and a metallic layer disposed therebetween, said connecting element having an outer rim which is positioned relative to the peripheral rim of said tubular body so that one overlaps the other, the superimposed layers of synthetic materials of said tubular body and said connecting element being welded to one another by inductive generation of heat in the metallic layers thereof and the exertion of pressure thereonto so that said synthetic material from at least one of said synthetic material layers of one of said connecting element and said tubular body is attached to the bevelled outer rim edge of said headpiece so as to overlie at least the interface of the upper and lower portions at said outer rim edge.
Claim 2
Dependent Claim

A packing tube, comprising: (a) a tubular body formed of a multi layered foil including a metallic barrier layer disposed between layers of synthetic material and having an inwardly directed peripheral rim; (b) a headpiece formed of synthetic material having a discharge opening, said headpiece including two superimposed portions, the lower portion completely covering the underside of the upper portion and formed of a non-permeable material, the outer diameter of said headpiece being less than the inner diameter of said tubular body, and said upper and lower portions forming an outer rim edge which is bevelled with respect to the central axis of the headpiece; and (c) a connecting element, disposed on said headpiece, including an upper and lower synthetic material layer and a metallic layer disposed therebetween, said connecting element having an outer rim which is positioned relative to the peripheral rim of said tubular body so that one overlaps the other, the superimposed layers of synthetic materials of said tubular body and said connecting element being welded to one another by inductive generation of heat in the metallic layers thereof and the exertion of pressure thereonto so that said synthetic material from at least one of said synthetic material layers of one of said connecting element and said tubular body is attached to the bevelled outer rim edge of said headpiece so as to overlie at least the interface of the upper and lower portions at said outer rim edge.
Claim 3
Dependent Claim
35 words
The packing tube as defined in claim 1, wherein the peripheral rim of said tubular body abuts the outer rim edge of said headpiece and is overlapped by the outer rim of said connecting element.
Claim 4
Dependent Claim
53 words
The packing tube as defined in claim 1, wherein said connecting element includes a step having a side which abuts the outer rim edge of said headpiece and the inwardly directed peripheral rim of said tubular body abuts the outer side of said step and overlaps the outer rim of said connecting element.
Claim 5
Dependent Claim
50 words
The packing tube as defined in claim 1, wherein the lower portion of said headpiece is provided with a cylindrical projection forming at least part of the inner wall of the discharge opening of said headpiece, and the upper portion of said headpiece is provided with an appropriate corresponding recess.
Claim 6
Dependent Claim
20 words
The packing tube as defined in claim 1, wherein the lower portion of said headpiece comprising a non-permeable synthetic material.
Claim 7
Dependent Claim
19 words
The packing tube as defined in claim 1, wherein the lower portion of said headpiece comprising a metallic material.
Claim 8
Dependent Claim
25 words
The packing tube as defined in claim 1, wherein the peripheral rim of said tubular body is overlapping the outer rim of said connecting element.
Claim 9
Dependent Claim
29 words
The packing tube as defined in claim 1, wherein the lower synthetic material layer of said connecting element is attached to the bevelled outer rim edge of said headpiece.
Claim 10
Dependent Claim
33 words
The packing tube as defined in claim 1, wherein at least one of the layers of synthetic material from said tubular body is attached to the bevelled outer rim edge of said headpiece.
