[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-stage stacking container for separately storing various items.

[0002]

2. Description of the Related Art Conventionally, multistage stacking containers have been known. This multi-stage stacking container is composed of a plurality of containers, and has an advantage that it is very convenient for stacking various things in separate containers and stacking them in a bulky manner for storage.

However, since the respective containers have a structure of simply stacking and fitting each other, even if an attempt is made to move the entire multi-stage stacking container by applying a force to the upper container, the fitting between the containers is performed. There was a case where it was difficult to move because it was out of sync.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention
An object of the present invention is to provide a multi-stage stacking container in which the mutual fitting of the containers is difficult to be disengaged even when a force is applied to the upper container.

[0005]

In order to solve the above problems, the present invention takes the following technical means.

The multi-stage stacking container of the present invention is formed by stacking a plurality of containers, and one container to be fitted with each other is formed with an outwardly projecting joint, and the other container is formed with the joint. It is characterized by comprising a connecting member which is rotatably hooked to.

Further, the joint portion can be implemented as having a plurality of ribs at a portion where the connecting member is hooked. Further, it is possible to implement it by having a collar portion on the outer circumference and forming irregularities on the collar portion. Further, it may be implemented as having a pair of carrying handles at outer facing positions.

[0008]

The present invention has the following actions.

The containers are stacked and fitted together. Then, by hooking the connecting member of the container on the other side to the joint portion protruding to the outside of the container on the one side, these can be integrated.

If the connecting member in the joint has a plurality of ribs at the hooked portion, even if there is a vertical play in the containers to be fitted to each other, the play will depend on the thickness of the ribs. Can be absorbed.

If the flange is provided on the outer circumference and the flange is provided with irregularities, the outer flange will come into contact when hitting a wall or the like, so that the impact on the container itself is buffered. It is possible to protect the stored items, and it is very easy to move because it is possible to touch the unevenness of the collar when moving it back and forth and left and right.

If a pair of carrying handles are provided at opposite positions on the outside, the whole can be carried as a whole by lifting the pair of handles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 8, the multi-stage stacking container of this embodiment comprises three containers 1 of high, middle and low height formed by synthetic resin molding. The container 2 is also provided with a lid body 2 formed by synthetic resin molding so as to correspond to the shape of the container 1.

The outer peripheral walls 3 of the three containers 1 constituting this multi-stage stacking container have a shape in which vertical irregularities are formed at regular intervals. Then, various items are stacked in the respective containers 1 and arranged so that they can be fitted to each other.

The containers 1 are formed so that they can be stacked in any order. In addition, casters 4 are provided at the four corners of the bottom of each container 1.
An insertion hole 5 (see FIG. 5) for mounting (see FIG. 1, not shown in and after FIG. 2) is formed. Therefore, the caster 4 can be attached regardless of which container 1 is placed at the bottom.

With respect to each of the three containers 1 having high, middle, and low heights, an outwardly projecting joint 6 is formed on the container 1 on one side to be fitted to each other, and the container 1 on the other side is Container 1
Is provided with a connecting member 7 which is rotatably hooked on the joint 6.

As shown in FIGS. 7 and 8, in this embodiment, the joint 6 formed on the upper container 1a is connected to the lower container.
Although the connecting member 7 provided in 1b is hooked, conversely, the connecting member 7 may be provided in the container 1a on the upper side to form the joint portion 6 in the container 1b on the lower side.

The ribs 9 in the horizontal direction are projected on the lower end sides of the front and rear end surfaces 8 of the respective containers 1 to form the joint portion 6 of the upper container 1a. The horizontal rib 9 is provided with a plurality of short ribs 10 projecting upward at a portion where the connecting member 7 is hooked, in a direction in which the connecting member 7 rotates.

On the other hand, the connecting member 7 of the lower container 1b is formed by synthetic resin molding into a generally V-shaped cross section.
A projecting piece 11 is extended from the outer edge of the projecting piece. A pair of opposed ribs 12 are formed on the front and rear end faces 8 of each container 1 so as to project in the vertical direction, and a fitting hole is formed in each rib. Then, the projections 13 projecting on both sides of the connecting member 7 are rotatably fitted into a pair of fitting holes formed in each rib 12.

Each of the containers 1 has a flange portion 14 projecting along the outer periphery thereof on both the upper end side and the lower end side thereof.
Further, the flange portion 14 is formed with vertical irregularities corresponding to the irregularities formed on the outer peripheral surface of the container 1.

In addition, the container having the highest height among the three containers 1 (arranged at the bottom in this embodiment) is provided with a pair of carrying "b" for carrying at outer facing positions. A handle 15 having a V shape is rotatably attached. This handle 15 is a container 1
It is rotatably fitted to the pair of vertical ribs 12 formed on the front and rear end faces 8 of the vertical direction.

Next, the state of use of the multi-stage stacking container of this embodiment will be described. In a state where various objects are divided into three containers 1 and arranged, the respective containers 1 are stacked and fitted to each other. Then, as shown in FIGS. 7 and 8, the connecting member 7 of the container 1b on the lower stage is hooked on the joint portion 6 protruding outward of the container 1a on the upper stage. Thereby, these containers 1 can be integrated. Therefore, there is an advantage that even if any one of the three containers 1, that is, the uppermost container 1 is subjected to a force, the fitting between the containers is not easily disengaged. That is, it is easy to move. Further, even when the entire container is tilted or swung when carrying the lower container 1b, the fitting between the containers is unlikely to be dislocated and stable.

Further, when the connecting member 7 of the lower container 1b is hooked on the joint 6 of the upper container 1a, the fitting between the containers is unlikely to accidentally come off or come out.
It is easy to move back and forth and left and right regardless of where you hold it, as it is difficult to rattle when putting it in and out of the closet.

In this embodiment, since a plurality of short ribs 10 are formed so as to project upward on the horizontal rib 9 of the joint portion 6 where the connecting member 7 is hooked, for example, a little more objects are provided. Even if there is some play in the vertical direction between the containers to be fitted to each other when they are stored too much, due to the elasticity due to the thickness of the short rib 10 made of synthetic resin, that play Can be absorbed and integrated with each other, and further, the same elastic function can enhance the sealing effect in the container.
A similar elastic function is imparted also by the protruding piece 11 extending from the outer end edge of the connecting member 7 formed by synthetic resin molding into a substantially V-shaped cross section. Also, the joint 6
Since the short rib 10 is formed so as to project toward the direction in which the connecting member 7 rotates, there is an advantage that the connecting member 7 can be smoothly introduced when hooked.

Further, when it hits a wall or the like, it comes into contact with the flange portion 14 projectingly formed on the outer periphery of the container 1, so that it is possible to buffer the shock to the container itself and protect the stored object. Since it is possible to touch the unevenness of the outer peripheral wall 3 when moving it in the front-rear direction and the left-right direction, there is an advantage that it is very easy to move.

Furthermore, a pair of grips at opposite outer positions
By lifting 15, there is an advantage that the whole can be carried together.

[0028]

The present invention having the above-mentioned structure has the following effects.

Since the containers to be fitted to each other can be integrated by the connecting member, it is possible to provide a multi-stage stacked container in which the fitting between the containers does not easily come off even if a force is applied to the upper container. .
