Container for fluid product

Abstract

A container ( 10 ) comprises a flexible body ( 30 ) with a side wall ( 35 ) globally directed along a longitudinal axis (A), and a ring-shaped top part ( 20 ) which has a dispensing opening ( 25 ) at one end ( 21 ) and which, at a second end ( 22 ) is adjacent to the side wall ( 35 ) of said flexible body ( 30 ), said ring-shaped top part ( 20 ) being stiffer than said flexible body ( 30 ). The dispensing opening ( 25 ) has an area which accounts for typically at least 60% of the envelope area of said ring-shaped top part ( 20 ) at the level of the first end ( 21 ).

1 ) A container comprising a flexible body with a side wall globally directed along a longitudinal axis (A), and a ring-shaped top part which has a dispensing opening at one end and which, at a second end is adjacent to the side wall of said flexible body, said ring-shaped top part being stiffer than said flexible body, wherein:
 a) said dispensing opening has an area which accounts for typically at least 60% of the envelope area of said ring-shaped top part at the level of the first end;   b) said ring-shaped top part has a cylindrical or prismatic outer surface;   c) said side wall of said flexible body, adjacent at a first end to the second end of said ring-shaped top part, is the continuation of said outer surface of said ring-shaped top part;   d) side wall has a second closed end, whose flattened shape results from joining the facing parts of the inner surface of a cylindrical sleeve whose section was initially that of the first end of said side wall.   
   
   
       2 ) A container according to  claim 1 , wherein said side wall is symmetrical in relation to a plane going through said axis (A) and the direction of said second end is closed and flattened. 
   
   
       3 ) A container according to  claim 1 , wherein the axis (A) is an axis of symmetry (rotational symmetry or n-order symmetry around an axis, n being an integer equal to or greater than 2) of the ring-shaped top part. 
   
   
       4 ) A container according to any of  claim 1 , wherein said ring-shaped top part has, at the level of said first end, an opening of diameter greater than 10 mm, preferably greater than 15 mm, preferably still greater than 19 mm. 
   
   
       5 ) A container according to  claim 1 , wherein said ring-shaped top part has, at the level of said first end, a top wall free of any excrescence, such as a tab or a pivoting cap, so that said ring-shaped top part has an easy to access rim surrounding said dispensing opening. 
   
   
       6 ) A container according to  claim 1 , wherein said ring-shaped top part has, at the level of said first end, a top wall free of any ruggedness so that said ring-shaped top part has an easy to access rim surrounding said dispensing opening, which can be used as a mouth to drink or swallow a product contained in said container. 
   
   
       7 ) A container according to  claim 1 , wherein the stiffness of the ring-shaped top part, provided by the thickness and/or the mechanical properties of the material(s) used to make said ring-shaped top part is sufficient for said container to be gripped with one's fingers placed on said ring-shaped top part without crushing said flexible body, that is, without suddenly decreasing the interior volume of said flexible body. 
   
   
       8 ) A container according to  claim 1 , wherein the height of said ring-shaped top part is chosen so that it facilitates gripping by a user's fingers of said flexible body. 
   
   
       9 ) A container according to  claim 1 , wherein said container also comprises a lid fixed, typically by gluing or heat sealing, to the top wall of the ring-shaped top part. 
   
   
       10 ) A container blank comprising a cylindrical or prismatic sleeve, globally directed along a longitudinal axis (A) and a ring-shaped top part having a dispensing opening at a first end, and being adjacent to said sleeve at a second end, said ring-shaped top part being stiffer than said sleeve, wherein:
 a) said dispensing opening has an area which accounts for typically at least 60% of the envelope area of said ring-shaped top part at the level of the first end;   b) said ring-shaped top part has a cylindrical or prismatic outer surface;   c) said sleeve of said flexible body, adjacent at a first end to the second end of said ring-shaped top part, is the continuation of said outer surface of said ring-shaped top part;   d) said sleeve has a second end which is open.
