Aseptic container for pourable foodstuffs

Abstract

The invention relates to an aseptic container (1) for pourable foodstuffs, having a development axis (H) that develops along a longitudinal direction (D). The container (1) comprises: a bottom wall (2); side walls (3) transversal to the bottom wall (2); and at least one top wall (4) opposed to the bottom wall (2). The side walls (3) are made of multilayer material comprising a plurality of layers overlapped one another, with at least one layer made of opaque material (30) and at least one layer made of transparent material (31). The container (1) further comprises: a plurality of openings (5, 5′) made in the opaque material layer (30) in at least one of the side walls (3), in such a way to be closed by the layer (31) of transparent material. In particular, the openings (5, 5′) are flanked each other along the longitudinal direction (D) and each opening (5, 5′) comprises a peripheral edge (50, 50′) defining a closed profile; wherein the maximum distance between two points of the peripheral edge (50, 50′) is between 4 and 8 millimeters.

1 . An aseptic container ( 1 ) for pourable foodstuffs, having a development axis (H) that develops along a longitudinal direction (D);
 the container ( 1 ) comprises: a bottom wall ( 2 ) that develops transversally with respect to the development axis; side walls ( 3 ), that are transversal with respect to the bottom wall ( 2 ); and at least one top wall ( 4 ) opposed to the bottom wall ( 2 );   the side walls ( 3 ) being made of multilayer material comprising a plurality of layers overlapped one another, with at least one layer made of opaque material ( 30 ) and at least one layer made of transparent material ( 31 );   the container ( 1 ) further comprises: a plurality of openings ( 5 ,  5 ′) made in the opaque material layer ( 30 ) in at least one of the side walls ( 3 ), in such a way to be closed by the transparent material layer ( 31 );   characterized in that:   the openings ( 5 ,  5 ′) are flanked each other along the longitudinal direction (D) and each opening ( 5 ,  5 ′) comprises a peripheral edge ( 50 ,  50 ′) defining a closed profile;   in which the maximum distance between two points of the peripheral edge ( 50 ,  50 ′) is between 4 and 8 millimeters.   
     
     
         2 . The container ( 1 ) according to  claim 1 , in which the side walls ( 3 ) are adjacent and connected each other by means of first bending lines ( 6 ); each of the bottom wall ( 2 ) and the top wall being connected to the side walls ( 3 ) by means of second bending lines ( 60 ); and in which the distance between each opening ( 5 ,  5 ′) and the proximal first bending line ( 6 ) and/or the proximal second bending line ( 60 ) is proportional to the maximum distance between two points of the respective peripheral edge ( 50 ,  50 ′). 
     
     
         3 . The container ( 1 ) according to  claim 2 , in which the distance between each opening ( 5 ,  5 ′) and the proximal first bending line ( 6 ) and/or the proximal second bending line ( 60 ) is between 4 and 16.5 millimeters. 
     
     
         4 . The container ( 1 ) according to  claim 1 , in which the distance between two adjacent openings ( 5 ,  5 ′) is between 11 and 12.5 millimeters. 
     
     
         5 . The container ( 1 ) according to  claim 1 , in which the peripheral edge ( 50 ,  50 ′) of the openings ( 5 ,  5 ′) is circular shaped. 
     
     
         6 . The container ( 1 ) according to  claim 1 , in which the openings ( 5 ,  5 ′) are arranged along a curved path that develops along said longitudinal direction (D). 
     
     
         7 . The container ( 1 ) according to  claim 1 , in which the openings ( 5 ,  5 ′) are arranged along two flanked and parallel rows. 
     
     
         8 . The container ( 1 ) according to  claim 1 , further comprising at least one reference sign disposed along the longitudinal direction (D), next to the openings ( 5 ,  5 ′), that represents the quantity of the foodstuff in the container. 
     
     
         9 . The container ( 1 ) according to  claim 1 , further comprising at least one covering strip ( 7 ) made of opaque material and detachably fixed above the openings ( 5 ,  5 ′). 
     
     
         10 . The container ( 1 ) according to  claim 9 , in which the covering strip ( 7 ) comprises aluminium.
