Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a sewing box that is frequently used in households or as a teaching tool.

[Conventional technology and its problems]

The most common conventional sewing box is one with a lid on the main body, but it is simply a container with a lid used to hold sewing tools, and at the same time it can hold the necessary fabrics and other materials. I can't organize my sewing tools,
Moreover, it is very troublesome to selectively take out tools during work. In order to solve this problem, relatively shallow inner trays with partitions to organize sewing tools were stacked on top of the main body of the box for storing fabrics and scraps, and then covered with a lid. Sewing boxes with similar configurations have also been devised and implemented;
Due to distortion of the constituent materials, etc., it is not possible to stack the inner tray on the box body and to cover the lid smoothly. If a gap for stacking is formed to solve this problem, it will cause backlash and other defects such as the corners of the inner tray falling into the box body. Furthermore, in the case of the conventional sewing box mentioned above, when taking out the sewing tools stored inside the box body, the tools cannot be taken out unless the lid and inner tray stacked on top of the box are lifted. There were problems with usability.

The present invention has been devised by focusing on these drawbacks, and is a sewing box with an inner tray that is easy to use, and can prevent the inner tray from accidentally falling into the box body. To provide a sewing box in which an inner plate can be stacked on a box body and a lid can be placed on the box body smoothly.

[Means for solving problems]

The present invention is characterized by a sewing box in which the bottom part enters the upper opening of the box body and is secured by the frame edge of the box body, and the lid is covered by overlapping the inner plates. A drawer is provided that penetrates one of the short side plates and retracts, and the outer side of the corner of the frame edge of the inner plate is formed to be inclined downward and outward, so that the lower edge of the corner of the frame edge is connected to the box body. This is done by making the top opening slightly protrude beyond the corner, and by creating a horizontal step by protruding a headband-shaped bulge on the body side circumferential surface of the inner tray that goes into the box body. A detailed explanation using an example is as follows.

〔Example〕

FIG. 1 is an exploded perspective view of a synthetic resin sewing box embodying the present invention, and FIG. 2 is an enlarged sectional view of the corner portion of the inner tray.

In the figure, reference numeral 1 denotes a box body with an opening at the top, and below the stacked space there is a short side plate of the box body 1 so that sewing tools (not shown) stored inside can be easily taken out. A drawer 3 is provided that penetrates one side of the drawer 2 and retracts from the drawer 3.

Reference numeral 4 denotes an inner tray that is stacked with its body dropped into the upper opening of the box body 1, and the radius of curvature of the lower edge of the frame edge corner portion 5 is set around the opening edge of the upper edge of the box body 1. A locking frame edge 7 with a slight protrusion 6 smaller than the curvature of the corner of the opening is formed, and a partially torn headband is formed on the body side circumferential surface of the inner plate 4 that enters into the box body 1. It has a structure in which a horizontal step 9 is formed by protruding a shaped raised portion 8.

Reference numeral 10 denotes a lid, which is deep enough to hide the locking frame edge 7 of the inner tray 4 when the crown is placed on the crown.

Therefore, the protrusion 6 of the locking frame edge 7 is
In order to smoothly cover the lid 10 on the box body 1 via the inner plate 4, its immediate upper end portion (the upper end portion of the outer side of the frame edge corner portion) is inclined downwardly and outwardly. It is formed in the shape of

Further, in the above embodiment, the headband-shaped raised portion and the resulting horizontal step are not formed in the vertical direction at the center of each side surface, that is, they are partially cut off, but they may be formed continuously.

[Functions and effects of the invention]

In the sewing box of the present invention having the above structure, the outer side of the corner of the frame edge of the inner tray is formed to be inclined downwardly and outwardly, and the lower edge of the frame edge corner is connected to the upper opening corner of the box body. In addition, we created a headband-shaped bulge on the body side circumferential surface of the inner plate that goes into the box body to form a horizontal step, so the slight protrusion at the corner part When dropping the inner tray into the box body, this prevents the locking frame edge from falling inadvertently, achieving reliable locking. Since the protruding portion is slidably contacted, the lid can be closed more smoothly than a lid that is slidably contacted over the entire circumferential surface, and the unsightly appearance caused by sliding scratches on the sliding surface is also eliminated. Furthermore, the headband-shaped protuberance on the circumference of the body of the inner plate acts as reinforcement for the body, minimizing distortion and deformation of the inner plate, and when stacking the inner plate on the box body. Since it acts as a guide and as a spacer to prevent rattling after stacking, it is possible to smoothly stack the box body and the inner tray, and to provide a product without rattling.

Moreover, in addition to these effects, according to the sewing box of the present invention, a drawer is provided at the bottom of the box body that penetrates one of the short side plates of the main body and appears and retracts, so that there is no space inside the box main body. When taking out the stored sewing tools, the tools can be taken out without lifting the lid and inner tray on the box body each time, and the usability is improved by that much compared to conventional sewing boxes. become.
