Description

[Detailed description of the invention] This invention is characterized by a smooth inner surface of the container and a stacking structure provided on the outer surface of the side wall. The present invention relates to a container that can be applied to double-sided stacking by a combination of the above, or to double-cross stacking by combining with relaxation containers of different shapes and sizes.

Embodiments will be described in detail below with reference to the drawings showing embodiments.

Fig. 1 shows a perspective view of the container of the present invention shaped in a certain shape by a resin, Fig. 2 shows a plan view thereof, and Fig. 3 shows a side view thereof.

The container A includes a bottom wall 1, a pair of opposing long side walls 2, a pair of short side walls 3 that are higher than the long side walls 2 by h, and a top provided on the upper edge of the short side walls 3 facing outward. An edge flange 4, a flange extension 5 continuous to both ends of the upper edge flange 4, that is, outside the width b1 of the short side wall, and a protrusion 6 provided at a corner of the flange extension 5; A lower flange 7 provided on the outside slightly above the lower end of the short side wall 3 (same as or smaller than h above), and a flange 4 with an upper edge at both ends of the short side wall 3.
The main structure is a vertical rib 8 whose lower end is connected to the end of the lower flange 7.

In addition, although the shape of the protrusion 6 is shown as a flat rectangular shape in the figure, it is not limited to this shape, and may be columnar, annular, or triangular. Part 6
It is desirable to make the wall thickness as uniform as possible using normal cutting techniques.

Also, the upper edge flange 9 of the long side wall 2, the vertical ribs 10 on both sides of the side wall 2, and the rib 11 connecting the lower ends of the vertical ribs 8 and 10.
The main purpose of these is reinforcement, and they do not need to be provided if they are unnecessary in terms of strength.

FIG. 4A shows a part of the front and side surfaces of the containers A shown in FIG.

As can be seen in the drawing, the upper and lower containers are stacked such that the lower flange 7 provided on the short side wall of the upper container is in contact with the upper edge flange 4 of the short side wall of the lower container, and the load is also transmitted there.

In addition, the reinforcing rib 11 of the upper container and the protrusion 6 of the lower container
It is also possible to make it so that they are in contact with each other.

In addition, the intersection portion 12 between the lower flange 7 and the vertical rib 8 of the upper container is in contact with the side surface of the protrusion 6 or is close to it with a slight gap, so that the container does not move in the direction parallel to the short side wall 3. It regulates movement.

Also, as can be seen from the same figure, the lower part 3 of the short side wall 3 of the upper container
' is located just inside the upper part 3'' of the short side wall 3 of the lower container, and restricts the movement of the containers in the direction along the long side wall.

When the containers of the present invention are piled up in a pile, the containers are completely prevented from shifting and even falling due to the above-mentioned movement restriction in the two directions.

Note that the opening in Figure 5A shows a partial cross-sectional view taken along lines I-I and III in Figure 4, and the bottom surface of the upper container is at the same height as the upper edge flange 9 of the long side wall 2 of the lower container. It can be seen that it is located slightly higher than that.

Also, there is a gap 31 on the long side wall side. This has the effect that the lower part of the long side wall 2 is positively provided with a slope 30 that is larger than the mold cutting slope normally provided, and even when there is no opening at all in the side wall, it is possible to check the stored items in the container from the gap. have

In FIG. 6, the distance between the outer edges of the upper edge flanges of the short side walls is a,
FIG. 2 is a perspective view showing a state in which two containers A whose distance between the outer edges of the upper edge flanges 9 of the long side walls is b and one container B whose size is aX2b are stacked in a parallel grid shape.

Note that this also includes the case where a=2b.

In this case, container B becomes a regular square. FIG. 7 is a diagram showing how containers A of the present invention and containers C other than the containers of the present invention are combined and stacked in parallel.

In the same figure, container C has almost the same shape as container B in FIG. It does not have the protrusion 6 as shown in FIG.

In this case, the lower flange 25 of the container C is in contact with the upper edge flange 4 of the short side wall 3, which is a high side wall of the lower container A, and the lower flange 26 on the other side is not in contact with the lower container A.

In addition, the lower flange 25 and corner flange 2 of the container C
7 is a narrow flange so that it does not overlap vertically with the protruding part 6 of the container A, or only that part is missing, and the flange 7 abuts the protruding part 6 laterally and moves in the direction of the arrow D of the container C. It is desirable to have a binding function that regulates the movement of.

When container A is stacked on container C in a parallel grid pattern, container A
The lower part of the container C than the lower flange 7 is fitted into the inside of the container C in a commonly used fitting manner, and does not shift in the vertical and horizontal directions.

As described above, the containers of the present invention can be stacked safely by preventing containers of the same size from being separated from each other, and at this time, the inside of the containers can be looked into even if there are no openings in the side walls of the containers.

Furthermore, if you combine containers with the same shape but different sizes, you can create a double stack.

In this case, even though it has a cross-stacking function, the inner surface of the container is smooth and has no unevenness for stacking, so when storing and transporting items of a certain shape and size inside the container, it is necessary to count each time. Even if you do not do this, if you store the items closely until they reach a certain height, you will be able to count them immediately, making the storage work extremely efficient.
