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.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to blocks with which utensils and toys can be produced in combination with PET bottles by coupling together just the blocks themselves or by attaching and linking the blocks to the PET bottles. [0003] 2. Description of the Related Art [0004] Couplers that can be fitted to and removed from bottom portions and top portions of PET bottles in order to utilize used PET bottles as utensils and toys, and which include peripheries disposed with coupling means for coupling together the couplers, are known from a prior application of the present inventors (Japanese Registered Utility Model No. 3099575). [0005] However, although the couplers can be coupled together in a horizontal direction in a state where they are not attached to PET bottles, they cannot be coupled together in a vertical direction. For this reason, there has been the problem that vertical utensils and toys cannot be produced wit...

AI Technical Summary

Benefits of technology

[0008] The blocks can be coupled together in a horizontal direction with the coupling means disposed at the peripheries of the frame portions, and can be coupled together straightly and diagonally (state where one upper block is positioned between two lower blocks) in a vertical direction by fitting together the frame portions and the leg portions. For this reason, flat or vertical utensils and toys can be formed with just the blocks themselves. Moreover, by attaching the blocks to the tops and bottoms of PET bottles, the PET bottles can be coupled in a horizontal direction and a vertical direction by coupling the blocks together to form vertical utensils and toys with PET bottles. Moreover, the blocks can easily be separated and taken apart so that it is easy to make other utensils and toys.

Problems solved by technology

However, although the couplers can be coupled together in a horizontal direction in a state where they are not attached to PET bottles, they cannot be coupled together in a vertical direction.

For this reason, there has been the problem that vertical utensils and toys cannot be produced with just the couplers themselves.
