Abstract

Abstract An article storing tray convenient for various partitioning includes a tray. The tray has a tray body having a plurality of drop-in dovetail grooves and also has at least one comb-toothed partition board having a plurality of through dovetail grooves with dovetail tenons at opposite ends of the partition board. With this configuration, the partition board can be dovetailed in two drop-in dovetail grooves of the tray body. The tray further has at least one sub-partition board having dovetail tenons at opposite ends of the sub-partition board so that the sub-partition board can be dovetailed in any of the drop-in dovetail grooves of the tray body and any of the through dovetail grooves to the comb-toothed partition board. In such a tray, by dovetailing the comb-toothed partition boards and the sub-partition boards in the dovetail grooves, the internal space of the tray body can be divided into a variety of compartments and these partition boards can be securely held.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 254 words
An article storing tray convenient for various partitioning, comprising: a tray body comprising a base having four sides, and opposing sidewalls extending upwardly from the four sides of the base, the base and side walls defining an internal space, each sidewall being provided with a plurality of drop-in dovetail grooves having a predetermined depth, each drop-in dovetail groove having a shape capable of accommodating a dovetail tenon; at least one comb-toothed partition board having opposite ends with dovetail tenons at the opposite ends so that the partition board can be dovetailed in two of the drop-in dovetail grooves of the tray body, each comb-toothed partition board being provided with a plurality of through dovetail grooves extending completely through the comb-toothed partition board in the direction of board thickness, the through dovetail grooves having the same depth as the drop-in dovetail grooves of the tray body, each through dovetail groove having a shape capable of simultaneously accommodating two dovetail tenons with longitudinal sides of the dovetail tenons facing each other, the through dovetail grooves providing flexibility to the comb-toothed partition board; and at least one sub-partition board having opposite ends with dovetail tenons at the opposite ends so that the sub-partition board can be dovetailed in any of the drop-in dovetail grooves of the tray body and can be dovetailed in any of the through dovetail grooves of the comb-toothed partition board, whereby the internal space of the tray body can be divided into various shapes by the at least one flexible comb-toothed partition board.
Claim 2
Dependent Claim 254 words
An article storing tray convenient for various partitioning, comprising: a tray body comprising a base having four sides, and opposing sidewalls extending upwardly from the four sides of the base, the base and side walls defining an internal space, each sidewall being provided with a plurality of drop-in dovetail grooves having a predetermined depth, each drop-in dovetail groove having a shape capable of accommodating a dovetail tenon; at least one comb-toothed partition board having opposite ends with dovetail tenons at the opposite ends so that the partition board can be dovetailed in two of the drop-in dovetail grooves of the tray body, each comb-toothed partition board being provided with a plurality of through dovetail grooves extending completely through the comb-toothed partition board in the direction of board thickness, the through dovetail grooves having the same depth as the drop-in dovetail grooves of the tray body, each through dovetail groove having a shape capable of simultaneously accommodating two dovetail tenons with longitudinal sides of the dovetail tenons facing each other, the through dovetail grooves providing flexibility to the comb-toothed partition board; and at least one sub-partition board having opposite ends with dovetail tenons at the opposite ends so that the sub-partition board can be dovetailed in any of the drop-in dovetail grooves of the tray body and can be dovetailed in any of the through dovetail grooves of the comb-toothed partition board, whereby the internal space of the tray body can be divided into various shapes by the at least one flexible comb-toothed partition board.
Claim 3
Dependent Claim 298 words
An article storing tray convenient for various partitioning, comprising: a tray body comprising a base having four sides, and two pairs of opposing sidewalls extending upwardly from the four sides of the base, the base and side wails defining an internal space, each sidewall being provided with a plurality of drop-in dovetail grooves having a predetermined depth, each drop-in dovetail groove having a shape capable of accommodating a dovetail tenon; at least one comb-toothed partition board having opposite ends, having a length sufficient to enable the partition board to extend between opposing drop-in dovetail grooves of at least one pair of the two pairs of opposing side wails of the tray body, and having dovetail tenons at the opposite ends so that the partition board can be dovetailed in one drop-in dovetail groove of each side wall between which the partition board is enabled to extend, each comb-toothed partition board being provided with a plurality of through dovetail grooves extending completely through the comb-toothed partition board in the direction of board thickness, the through dovetail grooves having the same depth as the drop-in dovetail grooves of the tray body, each through dovetail groove having a shape capable of simultaneously accommodating two dovetail tenons with longitudinal sides of the dovetail tenons facing each other, the through dovetail grooves providing flexibility to the comb-toothed partition board; and at least one sub-partition board having opposite ends with dovetail tenons at the opposite ends so that the sub-partition board can be dovetailed in any of the drop-in dovetail grooves of the tray body and can be dovetailed in any of the through dovetail grooves of the comb-toothed partition board, whereby the internal space of the tray body can be divided into various shapes by the at least one flexible comb-toothed partition board.
Claim 4
Dependent Claim 298 words
An article storing tray convenient for various partitioning, comprising: a tray body comprising a base having four sides, and two pairs of opposing sidewalls extending upwardly from the four sides of the base, the base and side wails defining an internal space, each sidewall being provided with a plurality of drop-in dovetail grooves having a predetermined depth, each drop-in dovetail groove having a shape capable of accommodating a dovetail tenon; at least one comb-toothed partition board having opposite ends, having a length sufficient to enable the partition board to extend between opposing drop-in dovetail grooves of at least one pair of the two pairs of opposing side wails of the tray body, and having dovetail tenons at the opposite ends so that the partition board can be dovetailed in one drop-in dovetail groove of each side wall between which the partition board is enabled to extend, each comb-toothed partition board being provided with a plurality of through dovetail grooves extending completely through the comb-toothed partition board in the direction of board thickness, the through dovetail grooves having the same depth as the drop-in dovetail grooves of the tray body, each through dovetail groove having a shape capable of simultaneously accommodating two dovetail tenons with longitudinal sides of the dovetail tenons facing each other, the through dovetail grooves providing flexibility to the comb-toothed partition board; and at least one sub-partition board having opposite ends with dovetail tenons at the opposite ends so that the sub-partition board can be dovetailed in any of the drop-in dovetail grooves of the tray body and can be dovetailed in any of the through dovetail grooves of the comb-toothed partition board, whereby the internal space of the tray body can be divided into various shapes by the at least one flexible comb-toothed partition board.
Claim 5
Dependent Claim 23 words

Claim 6
Dependent Claim 46 words
A tray as claimed in claim 1, wherein a step is formed in a lower outside portion of each sidewall of the tray body so that a lower portion of a first tray body can be stacked on a top edge of a second tray body.
Claim 7
Dependent Claim 45 words
A tray as claimed in claim 1, wherein each sidewall of the tray body has a top edge provided with a flange extending in an outer direction, the flange having a width allowing the tray body to be slidably stored in a predetermined storage device.
