Cap re-usable as interlocking building blocks

Abstract

The invention pertains to the field of caps and toys designed as building blocks, and relates in particular to a functional cap that can be re-used as a playing toy designed as interlocking or stackable blocks after the cap has been used for sealing packaging containers. The cap comprises a body ( 1 ) with a top surface ( 2 ) provided with projections ( 3 ) that can take the shape of rings, pins or any other shapes that fit into recesses or cavities ( 41 ) provided in the lower region of the body ( 1 ) or in structures provided in the sidewalls ( 5 ) thereof.

1 . Functional cap, able to be reused as a play toy in the form of interlocking/stackable blocks after its use as a package sealing element, characterized in that it comprises a body ( 1 ) with top surface ( 2 ) provided with projections ( 3 ) able to have the shape of rings, pins or any other shape, which fit into cavities or gaps ( 41 ) present in the lower region of the body ( 1 ) or in structures present on its lateral walls ( 5 ). 
     
     
         2 . Cap according to  claim 1 , characterized in that the body ( 1 ) is cylindrical and the planar top surface ( 2 ) is provided with projections in the form of rings ( 3 ), pins ( 4 ), or various geometrical shapes ( 5 ), arranged so as to produce tracks ( 6 ) for fitting the lower edge ( 7 ) of the lateral skirt ( 8 ) of the body ( 1 ) of a similar cap. 
     
     
         3 . Cap according to  claim 1 , characterized in that the body ( 1 ) has a substantially quadrangular cross section, with the top surface ( 2 ) provided with projections ( 3 ) able to have the shape of rings, pins or any other shape, which fit into cavities or gaps ( 41 ) present in the lower region of the body ( 1 ) or in structures present on its lateral walls ( 5 ). 
     
     
         4 . Cap according to any one of  claims 1  to  3 , characterized in that the cavities or gaps ( 41 ) have the same format as the projections ( 3 ). 
     
     
         5 . Cap according to any one of  claims 1  to  3 , characterized in that the cavities or gaps ( 41 ) have a different format from the projections ( 3 ). 
     
     
         6 . Cap according to any one of  claims 1  to  5 , characterized in that the body ( 1 ) has connection elements on all its surfaces—upper, lateral and/or lower—molded directly in its structure. 
     
     
         7 . Cap according to any one of  claims 1  to  6 , characterized in that the projections, the pins or the gaps ( 3 ,  4  or  5 ) occupy the total surface area of the body ( 1 ). 
     
     
         8 . Cap according to any one of  claims 1  to  6 , characterized in that the projections, the pins or the gaps ( 3 ,  4  or  5 ) occupy only the peripheral region of the surface ( 1 ) so that the central region ( 9 ) remains free to receive inscriptions, engravings, or various applications. 
     
     
         9 . Cap according to any one of  claims 1  to  6 , characterized in that the body ( 1 ) has a lateral skirt ( 8 ) provided with interlocking projections of the male ( 10 . 1 ) and female ( 10 . 2 ) type. 
     
     
         10 . Cap according to any one of  claims 1  to  6 , characterized in that the body ( 1 ) has a lateral skirt ( 8 ) provided with vertical locking elements ( 11 ) that are identical and self-coupling to each other. 
     
     
         11 . Cap according to any one of  claims 1  to  6 , characterized in that the surface ( 2 ) of the body ( 1 ) has four perimeter projections ( 5 ) arranged around a central projection ( 5 . 1 ). 
     
     
         12 . Cap according to any one of  claims 1  to  6 , characterized in that it contains two perimeter projections ( 5 ) provided with “male” type projections ( 12 ) for coupling in the “female” type internal region ( 13 ) of the other projections ( 5 ). 
     
     
         13 . Cap according to any one of  claims 1  to  6 , characterized in that the perimeter projections ( 5 ) contain proximal cavities ( 14 ) located in mutually orthogonal positions for coupling of the positioners ( 15 ) present at the lower end of the internal surface ( 16 ) of the body ( 1 ). 
     
     
         14 . Cap according to any one of  claims 1  to  6 , characterized in that the cavities ( 14 ) and the positioners ( 15 ) have any given geometrical conformation, as long as they are self-coupling. 
     
     
         15 . Cap according to any one of  claims 1  to  6 , characterized in that the body ( 1 ) contains an inner cylinder ( 17 ) as an auxiliary element for coupling of the caps. 
     
     
         16 . Cap according to any one of  claims 1  to  6 , characterized in that the inner cylinder ( 17 ) is employed as a compartment for placement of any given objects and closed by removable plastic film (F) or similar sealing element. 
     
     
         17 . Cap according to any one of  claims 1  to  6 , characterized in that the body ( 1 ) contains interlocking elements ( 10 . 1 ,  10 . 2  or  11 ) arranged on its upper surface ( 2 ).
