Pet bottle coupler

Abstract

A block is disclosed which comprises an upper frame portion and a lower leg portion that are integrally formed under the condition that the leg portion fits into the frame portion. The frame portion can be fitted to the bottom portion of a PET bottle and removed from it, the periphery of the frame portion being provided with coupling means that couple together adjacent blocks. The leg portion includes at a center portion thereof a receiving hole into and from which the top portion of a PET bottle is fitted and from which it is removed, the outside of the receiving hole being provided with gaps within which are sandwiched corresponding peripheral walls of the frame portions coupled together by the coupling means.

1 . A block comprising an upper frame portion and a lower leg portion that are integrally formed under the condition that the leg portion fits into the frame portion, wherein 
 the frame portion can be fitted to and removed from the bottom portion of a PET bottle, the periphery of the frame portion being provided with coupling means that couple together adjacent blocks, and wherein    the leg portion includes at a center portion thereof a receiving hole into and from which the top portion of a PET bottle is fitted and removed, the outside of the receiving hole being provided with gaps within which are sandwiched corresponding peripheral walls of the frame portions coupled together by the coupling means.    
   
   
       2 . A block as claimed in  claim 1 , further comprising locking convex ridges that engage with the peripheral surface of said bottom portion of said bottle and are disposed in the vertical directions of said peripheral walls of said upper portion.  
   
   
       3 . A block as claimed in  claim 1 , further comprising cuts placed in a peripheral wall of said receiving hole to form movable portions capable of elastic deformation and locking convex portions that engage with recessed portions disposed in a cap covering said bottle and are disposed at said movable portions.  
   
   
       4 . A combination coupler block and bottles that are removably attached together comprising: 
 a pair of bottles having respectively upper pouring portion and lower container walls and;    a coupler block having a first surface with a cavity of a size and configuration to removably secure the bottle container walls and a second surface to removably engage and return the upper pouring portion of the bottle.    
   
   
       5 . The invention of  claim 4  further comprising a third surface on the coupler block for interlocking with another coupler block.  
   
   
       6 . The invention of  claim 5  wherein the third surface is one of a male and female dove shaped connector.  
   
   
       7 . The invention of  claim 4  wherein the second surface includes a plurality of cantilevered tines for engaging the upper pouring portion.  
   
   
       8 . The invention of  claim 4  wherein the second surface is of a perimeter configuration to securely fit into the cavity of the first surface to enable a stacking connection of coupler blocks.  
   
   
       9 . The invention of  claim 4  wherein the first surface includes a plurality of locking ridges extending into the cavity for securing the container wall.  
   
   
       10 . A coupler block set that can be combined to construct objects alone or in combination with bottles that are removably attached together having respectively an upper pouring portion and a lower container wall comprising: 
 a coupler block having a first surface with a cavity of a size and configuration to removably secure the bottle container wall, a second surface to removably engage and retain the upper pouring portion of the bottle and a third surface on the coupler block for interlocking with another coupler block.    
   
   
       11 . The invention of  claim 10  wherein the third surface is one of a male and female dove shaped connector.  
   
   
       12 . The invention of  claim 11  wherein the second surface includes a plurality of cantilevered tines for engaging the upper pouring portion.  
   
   
       13 . The invention of  claim 12  wherein the second surface is of a perimeter configuration to securely fit into the cavity of the first surface to enable a stacking connection of coupler blocks.  
   
   
       14 . The invention of  claim 11  wherein the first surface includes a plurality of locking ridges extending into the cavity for securing the container wall.
