Container with a cross-section which changes between a square contour and a rectangular contour

Abstract

The invention relates to a container ( 1 ) made of plastic material, including a body ( 2 ) that extends along a main axis (X), a shoulder ( 3 ) which forms an extension of the body ( 2 ) on an upper side, and a base ( 5 ) which forms an extension of the body ( 2 ) on a lower side, the body having a square cross-sectional shape near the shoulder ( 3 ) as well as near 7 the base ( 5 ), and a rectangular cross-sectional shape in a median area of the body ( 2 ).

1 . Container ( 1 ) made of plastic material, comprising a body ( 2 ) that extends along a main axis (X), a shoulder ( 3 ) that forms an extension of the body ( 2 ) from an upper side, and a bottom ( 5 ) that forms an extension of the body ( 2 ) from a lower side, with the body comprising four faces ( 9 ,  10 ), namely a first pair of faces ( 9 ) that, in cross-section, are parallel to one another, and a second pair of faces ( 10 ) that, in cross-section, are parallel to one another and perpendicular to the faces ( 9 ) of the first pair, with the faces ( 9 ) of the first pair being separated, in the cross-section in the vicinity of the shoulder ( 3 ) as well as in the vicinity of the bottom ( 5 ), by a distance D, and the faces ( 10 ) of the second pair being separated, in the cross-section in the vicinity of the shoulder ( 3 ) as well as in the vicinity of the bottom ( 5 ), by a distance D′ that is equal or approximately equal to the distance D, with the values of D and D′ being such that: 
       
         
           
             
               0.95 
               < 
               
                 
                   D 
                   ′ 
                 
                 D 
               
               < 
               1.05 
             
           
         
       
       with this container ( 1 ) being characterized in that in the cross-section in a median zone of the body ( 2 ), the faces ( 9 ) of the first pair are separated by a first distance D 1  and the faces of the second pair ( 10 ) are separated by a second distance D 2  that is different from the distance D 1 . 
     
     
         2 . Container ( 1 ) according to  claim 1 , wherein the distances D 1  and D 2  are in a ratio of between 0.85 and 0.95. 
     
     
         3 . Container ( 1 ) according to  claim 2 , wherein the distances D 1  and D 2  are in a ratio of approximately 0.93. 
     
     
         4 . Container ( 1 ) according to  claim 1 , wherein at least one of the distances D 1  and D 2  is less than the distance D. 
     
     
         5 . Container ( 1 ) according to  claim 4 , wherein the distances D 1  and D 2  are both less than the distance D. 
     
     
         6 . Container ( 1 ) according to  claim 1 , wherein the body comprises beveled facets ( 11 ) connecting the faces ( 9 ,  10 ). 
     
     
         7 . Container ( 1 ) according to  claim 6 , wherein in the cross-section in the vicinity of the shoulder ( 3 ) as well as in the vicinity of the bottom ( 5 ), the facets ( 11 ) form an angle of approximately 45° with the faces. 
     
     
         8 . Container ( 1 ) according to  claim 6 , wherein in the cross-section in said median zone of the body ( 2 ), the facets ( 11 ) form an angle that is, strictly speaking, less than 45° with the faces ( 9 ) of the first pair. 
     
     
         9 . Container ( 1 ) according to  claim 8 , wherein in the cross-section in said median zone of the body ( 2 ), the facets ( 11 ) form an angle of between 37° and 43° with the faces ( 9 ) of the first pair. 
     
     
         10 . Container ( 1 ) according to  claim 9 , wherein in the cross-section in said median zone of the body ( 2 ), the facets ( 11 ) form an angle of approximately 40° with the faces ( 9 ) of the first pair. 
     
     
         11 . Container ( 1 ) according to  claim 7 , wherein in the cross-section in said median zone of the body ( 2 ), the facets ( 11 ) form an angle that is, strictly speaking, less than 45° with the faces ( 9 ) of the first pair.
