Structure of a stackable bucket

Abstract

A stackable bucket structure has a hollow body. The top end of the body is protruded upward with a neck part with an opening. The bottom end of the body has a concave accommodating part. The accommodating part has an inner sidewall edge and a supporting surface. The diameter of the inner sidewall of the accommodating part is slightly larger than the outer diameter of the neck part, so that the bucket can use its accommodating part to connect to the neck part of another bucket. When the accommodating part of one bucket connects to the neck part of another bucket, the supporting surface of the accommodating part urges against the top end of he neck part.

1 . A structure of a stackable bucket comprising a hollow body that protrudes upward with a neck part having an opening on the top end thereof and has a concave accommodating part at the bottom end thereof, wherein the accommodating part has an inner sidewall edge and a supporting surface, the diameter of the inner sidewall edge is slightly larger than the outer diameter of the neck part for the bucket to use its accommodating part to connect to the neck part of another bucket, and when the accommodating part and the neck part are connected the supporting surface of the accommodating part urges against the top end of the neck part of another bucket. 
     
     
         2 . The structure of a stackable bucket according to  claim 1 , wherein the neck part is formed with a connecting section, a shrinking limiting section is formed between the inner sidewall edge and the supporting surface, and when the accommodating part of the bucket and the neck part of another bucket are connected, the limiting section of the accommodating part urges against the connecting section of the neck part. 
     
     
         3 . A structure of a stackable bucket comprising a hollow body that protrudes upward with a neck part having an opening on the top end thereof and has a concave accommodating part at the bottom end thereof, wherein the neck part has a cover, the accommodating part has an inner sidewall edge and a supporting surface, the inner diameter and shape of the inner sidewall edge of the accommodating part match with the outer diameter and shape of the cover for the bucket to use its accommodating part to connect to the cover of the neck part of another bucket, and when the accommodating part and the neck part are connected the supporting surface of the accommodating part urges against the top surface of the cover of the neck part of another bucket. 
     
     
         4 . The structure of a stackable bucket according to  claim 3 , wherein the cover is formed with a connecting section toward its top end, a shrinking limiting section is formed between the inner sidewall edge and the supporting surface, and when the accommodating part and the cover on the neck part of another bucket are connected, the limiting section of the accommodating part urges against the connecting section on the cover.
