Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a transportation container that can suitably transport foods such as bread. The present invention relates to a transport container in which an upper transport container can be stacked extremely easily on top of the transport container.

[Prior art]

For example, Japanese Utility Model Publication No. 57-57009 discloses a device in which the upper end of the side wall is provided with recesses and recesses that fit into each other in order to stack containers in multiple stages to prevent them from collapsing.

However, in this conventionally known container, the locking structure is a vertically erected rib and a notch into which the rib fits, so there is a risk that the rib may be damaged and the load may collapse unexpectedly during use. That was a problem.

[Problems that ideas should solve]

The problem to be solved by the present invention is to provide a transportation container that is easy to stack, has a structure for stacking and locking, has high strength against impact forces, and is highly durable.

[Means to solve the problem]

The present invention for solving the above problems is based on a transportation container having a pair of tall short side walls facing each other at the bottom and a pair of low long side walls facing each other. An inner step portion 5 and an outer step portion 6 are formed, and a groove 1 is provided at the lower end of the tall short side wall 2 into which the top portion 4 of the lower container can be inserted when the containers are stacked in the same direction.
0 is sandwiched between an inner protrusion 11 and an outer protrusion 12, and the inner step 5 has an oblique side 7 having a small inclination angle toward the center of the inner step, at each position entering the inside from both left and right ends. A protrusion 9 consisting of a hypotenuse 8 with a large inclination angle is formed on the end side, and an inner protrusion 11 at the lower end of the tall short side wall 2 is fitted into the protrusion 9 of the lower container when the containers are stacked in the same direction. It is characterized in that a matching notch 13 is formed.

〔Example〕

The present invention will be explained below with reference to the drawings.

FIG. 1 is a top perspective view showing an example of a transportation container according to the present invention, FIG. 2 is a bottom perspective view showing an example of a transportation container according to the present invention, and FIG. 3 is a top perspective view showing an example of a transportation container according to the present invention. FIG. 4 is a partial cross-sectional view showing the state in which the containers for transportation according to the present invention are stacked, and FIG. FIG. 6 is a front view showing an example of the protrusion of the transportation container according to the present invention.

Transport containers are made of polyethylene, polypropylene,
It is made of synthetic resin such as ABS resin, and has a bottom portion 1, a pair of opposing tall short side walls 2, and a pair of opposing short long side walls 3.

An inner step portion 5 and an outer step portion 6 are formed at the upper end of the high short side wall 2, sandwiching the top portion 4 therebetween. The inner step 5 has protrusions 9 provided at respective positions entering the inner side from the left and right ends, with an oblique side 7 having a small inclination angle on the center side of the inner step part 5 and an inclined side 8 having a large inclination angle on the end side. is formed. The inclination angle α of the oblique side 7 is preferably 20 to 35 degrees, and the inclination angle β of the oblique side 8 is preferably 75 to 90 degrees.

An inner protrusion 11 and an outer protrusion 12 are formed at the lower end of the high short side wall 2, sandwiching a groove 10 into which the top part 4 can be inserted. The inner protrusion 11 has cutouts 13 that fit into the protrusions 9 at respective positions entering the inner side from both left and right sides.

In order to stack the containers according to the present invention so that they do not fall apart, as shown in FIGS. In other words, one end of the outer protrusion 12 and the inner protrusion 11 of the upper container is connected to the outer step 6 of the lower container so as to ride on the step 5 between the two protrusions 9 provided on the container 5.
Place the upper container on the inner step 5 and move it in the direction of arrow A while tilting it diagonally. After one end of the inner protrusion 11 of the upper container rises on the oblique side 7 with a small angle of inclination, turn the upper container horizontally. The protrusion 9 of the lower container may be fitted into the notch 13 of the upper container by
Stacking can be done extremely easily.

[Effect of idea]

When the containers according to the present invention are stacked in multiple stages, the protrusion 9 of the lower container is fitted into the notch 13 of the upper container as shown in FIG. Since the top portion 4 of the lower container is sandwiched between the protruding portion 11 and the outer protruding portion 12, it is possible to prevent the upper container from shifting forward, backward, left or right.

Furthermore, in the present invention, since the protrusion 9 is constituted by the oblique side 7 with a small inclination angle and the oblique side 8 with a large inclination angle, when the upper container is slid in the direction A from the state shown in FIG. Since the portion 11 overcomes the oblique side 7 having a small inclination angle, it can be smoothly carried out with little resistance. Once the containers are stacked, the oblique side 8 of the protrusion 9 having a large inclination angle comes into contact with the surface of the notch 13 provided correspondingly thereto, so that the effect of preventing the containers from slipping becomes great. Furthermore, since the protrusion 9 is tied to the oblique sides 7 and 8 of the container, it has extremely high rigidity against shocks during handling, and there is no risk of breakage.
