Abstract

A structure of a storage box includes a main body, a stacking assembly, and a forward opening. The main body has an upper and front-facing opening and a recess on the rear. The stacking assembly is attached to the main body, covers the upper and front-facing opening, and has an upper cover and a front cover, the upper cover fitted to the front cover with a snap and having a convex portion, the shape of the convex portion identical to the shape of the recess. The forward opening is a part of the upper and front-facing opening of the main body and is covered by the front cover. When two or more storage boxes are stacked, the convex portion of the second storage box embeds the recess of the first storage box, preventing the entire structure from tilting forward when the front cover of the storage box above is opened.

First claim

What is claimed is:

1 . An improved structure of a storage box comprising:
a main body having front and rear portions, with an upper and front-facing opening and a recess on the rear portion of the main body; a stacking assembly attached to the main body, said stacking assembly covering the upper and front-facing opening, wherein the stacking assembly has a upper cover and a front cover, the upper cover fitted the front cover with a snap and the upper cover has a convex portion, and the shape of the convex portion is identical to the shape of the recess; and a forward opening which is a part of the upper and front-facing opening of the main body, the forward opening is cover by the front cover.

2 . The improved structure of a storage box according to claim 1 , wherein the storage box comprises a stacking assembly formed by snap fitting the upper cover and front cover which is achieved by the following: at the corresponding front and back sections of the inside of said upper cover is formed a limiting section which maintains a preset height interval, and a preset height snap portion facing the limiting section, so that when the front cover is correspondingly positioned, the lower concave portion on one side of the periphery can be pushed in and held by said limiting portion, and the periphery on the other side of the front cover snaps into the snap portion so that the entire front cover is snapped to the inner surface of the upper cover; a predetermined part of the inner periphery of the upper cover is a clasp portion which has several channels so that in coordination with the main body, the cover of the upper opening is able to snap into the bottom portion of an annular flange.

3 . The improved structure of a storage box according to claim 1 , wherein the storage box comprises a groove recessed into a preset section of the inside of the upper cover, into which a coordinating reinforcing panel is placed for additional strength when storage boxes are stacked on top of each other.

4 . The improved structure of a storage box according to claim 1 , wherein the storage box comprises a lower surface formed on a preset section of the inside of the main body towards its front, so that the front cover on the bottom of the stacking assembly can be pushed in or slid out along said flat surface by means of the slightly protruding rounded convex portion on either side.

5 . The improved structure of a storage box according to claim 1 , wherein the storage box comprises a concave portion protruding from the back section of the upper cover of the upper opening of the main body which matches the bottom adjacent concave portion on the bottom of the main body of the storage box into which it can be introduced when stacking so as to make the stacking between storage box and storage box more stable; and at the bottom of the main body, the preset corners are protruded with a plurality of convex portions which match the recessed area recessed in the middle of the upper cover which covers the upper opening of the main body when being stacked.

6 . The improved structure of a storage box according to claim 1 , wherein the storage box comprises a raising support of extending channels on a predetermined part of the outer side of the upper periphery of the main body, which when multiple main bodies are not being used and are stacked with one another, said raising support is positioned in the corresponding indented section of the adjacent main body below to maintain an appropriate interval and facilitate being unstacked for further use.

7 . The improved structure of a storage box according to claim 1 , wherein the storage box comprises a concave portion recessed on both sides at the rear of the upper cover which covers the upper opening of the main body, and allows the snap fitted stacking assembly of the upper cover and front cover when not in use and being stacked with one another to be introduced into the rounded convex portion on the corresponding part of the front cover on the inside so that the upper and lower stacking assemblies can be stacked in a stable manner.
