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).

Claims

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.
