[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The transport container of the present invention basically comprises a substantially rectangular parallelepiped container whose upper part is opened by a rectangular bottom plate and side walls erected from the four peripheral edges of the bottom plate. It has a structure capable of stacking and nesting.

As is already known, the above-mentioned stacking is achieved by placing the legs of the upper container body on the upper surface of the flange of the lower container body, and nesting is performed by the legs of the upper container body. This is achieved by fitting into the pocket portion of the lower container body.

In the transport container of the present invention, the bottom of the pocket portion formed in the container main body is formed on a slope inclined downward toward the inside of the container main body, and this inclined surface is formed as a flat inclined surface. It may be one that is formed by an inclined surface curved in an arch shape.

In addition to forming such a flat inclined surface or a curved inclined surface, a portion linked to the pocket portion and the inner wall portion of the container body is formed into a curved shape by a predetermined arc (R). Is preferred.

The transport container is preferably made of a synthetic resin such as polyethylene or polypropylene from the viewpoint of ease of molding and durability. The bottom plate portion and each side wall portion of the container main body constituting the transport container may be a container having a net-like hole.

[0016]

The bottom portion of the pocket portion of the container body in the transport container according to the present invention is formed as a slope having a downward slope toward the inside of the container body, so that fine parts and the like stored in the container body can be placed on the inclined surface. Even if it falls into the container body, it does not stagnate as it is, and it easily slides down this inclined surface and falls into the container body, so that the inside of the pocket portion can always be kept empty.

Also, in addition to forming a flat inclined surface or a curved inclined surface, a portion linked to the pocket portion and the inner wall portion of the container body is not formed into an angular shape, but is curved by a predetermined arc (R). By doing so, it is possible to prevent dust from adhering and accumulating on this corner portion.

Furthermore, since the inclined surface and the curved corner portion allow the pocket portion to be gently connected to the inner side surface of the container main body without the corner, the contents stored in the container main body can be connected to the corner of the pocket portion. Can be prevented from being damaged.

In addition, the dead space below the pocket portion of the lower container body formed to receive the support leg of the upper container body can be reduced.
