Tube head, and tube comprising said tube head

Abstract

A head for manufacturing a flexible tube for containing a liquid or pasty product, comprising an upper wall and an annular side wall, the lower distal end of which defines a plane (A), said head comprising a dispensing orifice extended by a protuberance, a portion of which protrudes from said plane (A), said protruding portion being eccentric relative to the center of the tube head.

1 . A head for manufacturing a flexible tube intended to contain a liquid or pasty product, the head comprising an upper wall and an annular lateral a lower distal end of which defines a plane (A), said head comprising a dispensing orifice extended by a protuberance, a segment of which protrudes from said plane (A), said protruding segment being eccentric with respect to a center of the head. 
     
     
         2 . The head according to  claim 1 , wherein the head has at least two ribs at a level of an internal face of the upper wall. 
     
     
         3 . The head according to  claim 1 , wherein at least one portion of the protuberance extending the dispensing orifice has the shape of a half-cylinder. 
     
     
         4 . The head according to  claim 3 , wherein the dispensing orifice is eccentric with respect to the center of the tube head. 
     
     
         5 . The head according to  claim 1 , said head comprising a hinged cover connected to the tube head by a hinge and movable between an open position and a closed position, said head, the hinged cover and the hinge consisting of a single piece. 
     
     
         6 . The head according to  claim 5 , wherein the tube head is configured so that, when the hinged cover is in the closed position, said hinged cover forms a substantially planar surface with the first upper wall. 
     
     
         7 . The head according to  claim 5 , wherein the annular lateral wall has an undercut and the cover comprises a tab, said undercut and said tab making it easier for a finger of a user to open the cover. 
     
     
         8 . The head according to  claim 1 , said head having a height h 1  of between 5 and 20 mm. 
     
     
         9 . The head according to  claim 1 , wherein a diameter d of the tube head is between 20 and 60 mm, in particular between and 50 mm. 
     
     
         10 . The head according to  claim 8 , wherein a ratio d/h 1  is between 2 and 6. 
     
     
         11 . The head according to  claim 1 , wherein the protruding segment has a height h 2  of between 1.5 and 6 mm. 
     
     
         12 . The head according to  claim 1 , wherein a thickness of material at the level of the first upper wall and of the annular lateral wall is between 0.3 and 2 mm. 
     
     
         13 . A tube comprising a tube head according to  claim 1  and a flexible skirt, said tube comprising at least 50% by mass of paper. 
     
     
         14 . The tube as claimed in  claim 13 , wherein the flexible skirt is attached directly to the tube head. 
     
     
         15 . The head according to  claim 8 , wherein the height h 1  is between 8 and 12 mm. 
     
     
         16 . The head according to  claim 9 , wherein the diameter d of the tube head is between 30 and 50 mm. 
     
     
         17 . The head according to  claim 10 , wherein the ratio d/h 1  is between 3 and 5. 
     
     
         18 . The head according to  claim 11 , wherein the height h 2  of the protruding segment is between 2 and 4 mm. 
     
     
         19 . The head according to  claim 12 , wherein the thickness is between 0.5 and 1 mm.
