Abstract

The present invention relates to a flexible tube for a product having a liquid or pasty consistency, comprising:
a tube head ( 1 ) comprising a shoulder ( 12 ) and a neck ( 11 ), a skirt ( 2 ) having a proximal end ( 21 ) which is connected to the tube head ( 1 ) and a free distal end ( 22 ), the skirt ( 2 ) forming an internal volume which is adapted to contain a product having a liquid or pasty consistency,

characterized in that the proximal end ( 21 ) of said skirt ( 2 ) comprises a plurality of flaps ( 24 ) and a plurality of notches ( 23 ) separating said flaps ( 24 ), said flaps ( 24 ) being folded so as to cover all or part of the shoulder ( 12 ).

First claim

The invention claimed is:

1. A flexible tube for a product having a liquid or pasty consistency, comprising:
a tube head comprising a shoulder and a neck,
a skirt having a proximal end which is connected to the tube head and a free distal end, the skirt forming an internal volume which is adapted to contain a product having a liquid or pasty consistency,
characterised in that the proximal end of said skirt comprises a plurality of flaps and a plurality of notches separating said flaps, said flaps being folded so as to cover all or part of an outer surface of the shoulder, the skirt forming a cylinder of revolution, the plurality of notches comprising between 12 and 32 notches, and the flaps all having the same shape.

2. Tube according to claim 1 , wherein said flaps are folded so as to cover at least 50% of the outer surface of the shoulder of the tube head.

3. Tube according to claim 2 , wherein said flaps are folded so as to cover all of the outer surface of the shoulder of the tube head.

4. Tube according to claim 2 , wherein the tube head further comprises an insert which is arranged so as to rest against the shoulder, so as to form a barrier between the tube head and a product contained in the internal volume defined by the skirt.

5. Tube according to claim 1 , wherein said flaps are folded so as to cover all of the outer surface of the shoulder of the tube head.

6. Tube according to claim 5 , wherein the tube head further comprises an insert which is arranged so as to rest against the shoulder, so as to form a barrier between the tube head and a product contained in the internal volume defined by the skirt.

7. Tube according to claim 1 , wherein the tube head further comprises an insert which is arranged so as to rest against the shoulder, so as to form a barrier between the tube head and a product contained in the internal volume defined by the skirt.
