Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a square container that can be suitably used for transporting and storing various parts, various foods, etc. In particular, the present invention relates to a rectangular container devised so that a conventionally used large container can be stacked on top of two rectangular containers arranged in parallel.

``Prior art'' A square container is known that is designed to allow conventionally used large containers to be stacked on top of two square containers arranged in parallel. Since the fitting means with the large containers provided to allow containers to be stacked stably has a large volume, it takes time to cool down during molding, prolonging the molding time, and the fitting means is subject to molding shrinkage. There were drawbacks such as deformation due to the formation of cracks.

``Problems to be solved by the invention'' The inventor of the present invention found that although a means for fitting large containers is provided so that large containers can be stacked stably, the molding time does not become long, and the fitting As a result of conducting research into a square container that does not deform due to molding shrinkage, the present invention was arrived at.

"Means for Solving the Problems" The present invention provides a rectangular container having a bottom, a side wall formed along one opposing side of the bottom, and a side wall formed along the other opposing side of the bottom. The length of the side wall formed along one side of the large container is approximately half the length of the side wall formed along the opposite side of the large container, and the length of the side wall formed along the other side is approximately half of the length of the side wall formed along the opposite side of the large container. The length of the side wall formed along the opposite side of the container is approximately equal to the length of the side wall formed along the opposite side of the container, and the side wall formed along one side is made one step higher than the side wall formed along the other side, and the side wall formed along the other side is A cross-shaped protrusion is formed on the flange provided along the upper edge of the formed side wall to fit into the recess formed by the ribs provided vertically and horizontally at the bottom of the large container. The present invention relates to a characteristic square container.

"Example" The present invention will be described below with reference to the drawings.

Figure 1 shows an example of a rectangular container according to the present invention, the right half of Figure 1 is a plan view of the right half, the left half of Figure 1 is a bottom view of the left half, and Figure 2 is a book The right half of Figure 2 shows a cross-sectional view of the right half, the left half of Figure 2 is a front view of the left half, and Figure 3 shows the square container according to the invention. FIG. 4 is a partially cutaway perspective view showing a conventional large container stacked on top of a container; FIG. 4 is a cross-sectional view showing a conventional large container stacked on top of a rectangular container according to the present invention; FIG. 6 is a partial plan view showing a conventional large container stacked on top of the square container according to the present invention, and FIG. 6 is a partial plan view showing a conventional large container stacked on top of the square container according to the present invention. FIG.

The square container is molded from a synthetic resin such as polyethylene or polypropylene, and has a bottom 1 and a bottom 1.
A side wall 2 formed along one opposing side of the bottom portion 1 and a side wall 3 formed along the other opposing side of the bottom portion 1.
have. The length of the side wall 2 formed along one opposing side of the square container is approximately half the length of the side wall 5 formed along one opposing side of the conventional large container 4. The length of the side wall 3 formed along the other side of the conventional large container 4 is approximately equal to the length of the side wall 6 formed along the opposite side of the conventional large container 4. In a square container, the side wall 2 formed along one side is one step higher than the side wall 3 formed along the other side, and the side wall 2 formed along the other side is made higher than the side wall 3 formed along the other side. A cross-shaped protrusion 11 is formed on the provided flange 7 to fit into a recess 10 formed by ribs 9 provided vertically and horizontally on the bottom 8 of the large container 4. In FIGS. 1 to 6, two cross-shaped protrusions 11 are formed at positions slightly inward from the end of the side wall 3, but one or three or more may be formed. It's good too,
It may be formed in the center of the side wall 3 if necessary.

After arranging the two square containers in parallel, the cross-shaped protrusions 11 of each are placed on the bottom 8 of the conventional large container 4.
If the large containers 4 are stacked while being fitted into the recesses 10 formed by the ribs 9 provided vertically and horizontally, a conventional large container can be placed on top of the two square containers without shifting forward, backward, left or right. Can be stacked stably.

"Effects of the invention" In the square container according to the invention, since the means for fitting with the large container 4 is the cross-shaped protrusion 11 and the volume is small, cooling during molding does not take much time and the molding time is prolonged. Furthermore, the fitting means will not be deformed due to molding shrinkage.
