Compact batch of grouped containers and method for packaging same

Abstract

A batch comprising at least two containers and at least one strip. The strip holds the containers together, wherein each of said containers has a body and a bottom aligned in a main direction, the at least one strip covers said batch at the peripheral wall of the body of said container. In example embodiments, the at least one strip comprises semi-extensible paper. Additional aspects of the present invention relate to a method for packaging such a batch of containers and a paper retaining strip for such a batch and to the use, in the form of a strip, of such a semi-extensible paper for holding the containers together within such a batch.

A batch comprising at least two containers and at least one strip that holds them grouped together, said containers each having a body and a bottom aligned in a main direction, the at least one strip wrapping said batch at the level of the peripheral wall of the body of said container, wherein the at least one strip is a strip of semi-extensible paper. 
     
     
         2 . The batch as claimed in  claim 1  characterized in that said at least one strip has an index of energy at rupture of at least 180 J/m 2 . 
     
     
         3 . The batch as claimed in  claim 1 , wherein the strip of semi-extensible paper comprises properties of elongation at rupture greater than 5% and a resistance to traction greater than or equal to 5 kN/m. 
     
     
         4 . The batch according to  claim 1 , wherein said at least one strip of semi-extensible paper has a weight per unit area between 50 and 120 g/m 2  inclusive and preferably between 70 and 90 g/m 2  inclusive. 
     
     
         5 . The batch according  claim 1 , wherein said at least strip of paper has tear properties greater than 10 mN·m 2 /g. 
     
     
         6 . The batch of  claim 1 , wherein the at least one strip comprises a single strip of semi-extensible paper. 
     
     
         7 . The batch of  claim 1 , wherein in the main direction the at least one strip of semi-extensible paper has a minimum height of one eighth of the height of the containers, preferably a minimum height of one quarter of the height of the containers. 
     
     
         8 . The batch of  claim 1 , wherein the at least one strip of semi-extensible paper has at least one coating. 
     
     
         9 . The batch according to  claim 8 , wherein the at least one coating has a weight per unit area between 4 and 30 g/m 2  inclusive. 
     
     
         10 . The batch of  claim 1 , further comprising an additional adhesion means at the level of the contact zone formed by applying the retaining strip to the peripheral wall of the containers, said additional adhesion means being initially placeable either on the contact zone or on the interior face of the corresponding strip, or both. 
     
     
         11 . The batch of  claim 1 , further comprising a handle in the form of at least one strap fixed by partially overlapping at least one retaining strip. 
     
     
         12 . The batch according to  claim 1 , wherein the batch comprises:
 at least four containers,   at least one sub-batch comprising at least two of said containers,   at least one closed strip of paper that holds said containers forming the sub-batch together.   
     
     
         13 . A retaining strip of semi-extensible paper for holding together a batch of at least two containers. 
     
     
         14 . A method for packaging at least two containers in a batch comprising:
 providing at least two containers, each container comprising a body and a bottom;   grouping together the at least two containers so as to be aligned in a main direction;   providing at least one strip of semi-extensible paper; and   wrapping the batch with the at least one strip perpendicular to the main direction,   
       wherein the at least one strip of semi-extensible paper exerts a force between about 0.2 and 5 kN/m inclusive at the level of the peripheral wall of the containers, once applied thereto. 
     
     
         15 . An installation for packaging at least two containers in batches as claimed in  claim 1 . 
     
     
         16 . A batch comprising at least two containers and at least one strip that holds them grouped together, the containers each having a body and a bottom aligned in a main direction, the at least one strip wrapping said batch at the level of the peripheral wall of the body of said container, wherein the at least one strip is a strip of semi-extensible paper, wherein the semi-extensible paper comprises an index of energy at rupture of at least 180 J/m 2 , properties of elongation at rupture greater than 5% and a resistance to traction greater than or equal to 5 kN/m, and a weight per unit area between 50 and 120 g/m 2  inclusive and preferably between 70 and 90 g/m 2  inclusive.
