BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage container suitable for storing and storing household accessories, clothes, and the like. In particular, when storage containers are stacked and stored in a closet or the like, the stacked state is maintained. The present invention relates to a storage container in which storage items in a lower storage container can be put in and taken out.

[0002]

2. Description of the Related Art As a conventional storage container, for example, the one shown in FIGS. 8A and 8B has been proposed (see Japanese Utility Model Laid-Open No. 3-23037). That is, each storage container 5
1A and 51B are composed of a container main body 52 and a lid 53 that covers the upper opening of the container main body 52. The lid 53 is formed by mutually connecting the opened / closed lids 53a and 53b with a thin connecting portion 54. By connecting, each open / close lid 53
A and 53b can be opened and closed independently of each other with the connecting portion 54 as a fulcrum.

When the storage containers 51A and 51B are stacked as shown in FIG. 8 (B), the lower storage container 51A is pulled out to about half of the storage container 51A or the upper storage container 51A. By pushing the first storage container 51B backward to about half thereof and moving it, one of the lids 53b of the lower storage container 51A is opened and closed without opening and closing the upper storage container 51B, and the necessary items are opened and closed. Can be taken in and out.

[0004]

However, in such a conventional storage container, the open / close lid 53a or 5a of the lower storage container 51A in the stacked state.
When opening and closing 3b, the upper storage container 51B is simply moved while sliding on the lower storage container 51A, and therefore, depending on the weight of the storage items stored in the upper storage container 51A. In some cases, the sliding resistance when moving the upper storage container 51A becomes too large, and the upper storage container 51A cannot be moved smoothly.

In order to improve the mobility of the storage containers, some of the storage containers 51A and 51B have been provided with casters (wheels) at the bottom of the container body 52. Although the individual storage containers can be easily moved when used alone, when the storage containers are stacked as described above, not only the stability of the upper storage container is lost but also the lower storage container. If the upper storage container is slid on the lower storage container to open and close the opening / closing lid, on the contrary, the momentum is too good and the upper storage container falls from the lower storage container. Even if it does not fall or falls, the casters of the upper storage container may come off from the lower storage container and the upper storage container may be tilted.

The present invention has been made in view of the above-mentioned conventional problems, and has the following advantages. The easiness of movement of the storage container by providing wheels, and the opening and closing of the opening and closing lid of the lower storage container in a stacked state. It is an object of the present invention to provide a storage container structure in which the upper storage container is prevented from dropping or tilting when opening and closing the lower storage container opening / closing lid while ensuring the convenience that can be provided. It is.

[0007]

In order to solve the above-mentioned problems, in the invention of claim 1, a cover is placed over an upper opening of a container body having wheels at front, rear, and center of a bottom. In a stackable storage container, the lid is divided into two opening and closing lids hinged to each other, each opening and closing lid is configured to be independently openable and closable, and the upper storage container in a stacked state And a lower storage container that is relatively slidable so that one of the lids of the lower storage container can be opened and closed, wherein a stopper is provided at the bottom of the container body. When opening and closing one open / close lid of the lower storage container in the stacked state, the upper and lower storage containers are slid relatively to the openable / closable position of the open / close lid. The stopper portion abut to form a stopper contact portion to restrict the relative sliding amount of the container of the upper lower when allowed.

According to the invention of claim 2, in addition to the structure of claim 1, the stopper portion also serves as a reinforcing rib formed in a cross-girder shape on the bottom of the container body.
In the device of the present invention, in addition to the configuration of the first aspect, the stopper abutting portion also serves as a reinforcing embossed portion formed on the lid.

Further, in the invention of claim 4, in addition to the constitution of claim 1, when the upper and lower storage containers in the stacked state are relatively slid on the lid, the upper storage container is moved. A guide groove for guiding wheels is formed. According to the invention of claim 5, in addition to the configuration of claim 4, the upper and lower storage containers in a stacked state are relatively provided on the bottom surface of the guide groove of the lid. Before and after sliding, the receiving recess for receiving the wheel of the upper storage container and positioning the upper storage container is formed.

[0010]

In the above construction, when the upper storage container of the stacked storage containers is slid on the lower storage container, the rear wheel of the upper storage container is temporarily moved from the lower storage container to the lower storage container. Even if the upper and lower wheels are on the lower storage container, the horizontal storage container can be maintained in the horizontal position without falling or tilting as long as the front and center wheels are on the lower storage container. Then, when the upper storage container is slid to a position where one of the opening / closing lids of the lower storage container lid can be opened and closed, the stopper portion comes into contact with the stopper abutting portion, so that further movement is possible. The sliding movement of the upper storage container is prevented.
