Stackable Independent Container System

Abstract

Stackable container system ( 10 ), comprising a plurality of stackable elements ( 11,12 ), mutual releasable clamping means being provided between one element and the next, made up of hooking means ( 18,20 ) present near the top periphery of each stackable element ( 11, 12 ) and retaining means ( 21,22 ) of an upper element extending from at least one side of said upper stackable element ( 11,12 ) near a lower portion thereof, characterised in that said stackable elements are made up of container elements ( 11 ) and closing elements ( 12 ) of at least part of said containers ( 11 ).

1 . Stackable container system ( 10 ), comprising a plurality of stackable elements ( 11 , 12 ), mutual clamping releasable means being provided between one element and the next, made up of hooking means ( 18 , 20 ) present near the top periphery of each stackable element ( 11 ,  12 ) and retaining means ( 21 , 22 ) of an element above extending from at least one side of said stackable element ( 11 , 12 ) above near a lower portion thereof, characterised in that said stackable elements are made up of container elements ( 11 ) and closing elements ( 12 ) of at least part of said containers ( 11 ). 
   
   
       2 . System according to  claim 1 , characterised in that the hooking means ( 18 , 20 ) of a lower element ( 11 , 12 ) hook to the retaining means ( 21 , 22 ) of an upper element. 
   
   
       3 . System according to  claim 1 , characterised in that said mutual releasable clamping means are provided on the transversal sides ( 15 , 16 ) of each element ( 11 , 12 ). 
   
   
       4 . System according to  claim 1 , characterised in that said hooking means ( 18 , 20 ) comprise at least one folding winglet ( 18 ), presenting in the middle an opening ( 20 ), and said retaining means ( 21 , 22 ) comprise a retaining tooth ( 21 , 22 ) hookable to said opening ( 20 ). 
   
   
       5 . System according to  claim 1 , characterised in that said winglet ( 18 ) is arranged near the top edge of each container element ( 11 ). 
   
   
       6 . System according to  claim 1 , characterised in that said winglet ( 18 ) is located at the perimeter of the top surface of each closing element ( 12 ). 
   
   
       7 . System according to  claim 5 , characterised in that said winglet ( 18 ) is made of flexible material and is hinged to said container elements ( 11 ), and respectively to said closing elements ( 12 ), by means of a line of lesser resistance. 
   
   
       8 . System according to  claim 1 , characterised in that said covering element ( 12 ) presents a central depression ( 8 ) formed in a complementary manner in relation to a bottom portion ( 17 ) of said container element ( 11 ). 
   
   
       9 . System according to  claim 1 , characterised in that said covering element ( 12 ) presents a recessed seat ( 13 ) provided with a retaining tooth ( 23 ) for the housing of said hooking means ( 18 , 20 ). 
   
   
       10 . System according to  claim 1 , characterised in that each container element ( 11 ) presents external dimensions of its top which are complementary to the internal dimensions of the free end ( 14 ) of the walls of each covering element ( 12 ), in such a way as to ensure hooking with light effort between the two elements ( 11 , 12 ). 
   
   
       11 . System according to  claim 1 , characterised in that each container element ( 11 ) presents external dimensions of its bottom section ( 17 ) which are complementary to the internal dimensions of its top in such a way as to ensure hooking with light effort between the two elements ( 11 , 12 ).  12 . System according to any one of the previous claims, characterised in that the edges of said containers ( 11 , 12 ) have a variable height.
