Description

[Detailed Description of the Invention] The present invention relates to a packaging container for a micro motor, particularly a packaging container for a micro motor manufactured by molding a synthetic resin sheet.

Conventionally, as packaging containers for transporting micro motors, containers made of expanded polystyrene as shown in FIG. 1 have often been used. That is, FIG. 1 shows a perspective view of an embodiment of the conventional foamed polystyrene container, in which reference numeral 1 represents the container, 2 represents a micro motor, and 3 represents a motor housing recess.

In FIG. 1, a motor accommodating recess 3 having a shape corresponding to the outer shape of a micro motor 2 is arranged on a box-shaped styrofoam container 1 at an appropriate interval. The micro motor 2 is housed in each of the motor housing recesses 3 as shown in FIG. Then, the containers 1 containing the micro motors 2 are stacked as shown in FIG. 2, which shows a cross-sectional view taken along arrow X-X' in FIG. . The conventional micro-motor packaging means using the Styrofoam container 1 described above has the following problems. That is, (a) Styrofoam is weak in terms of strength, so it is necessary to increase the strength of the container by increasing the wall thickness of the container or adding reinforcement parts. Therefore, the housing space for each motor becomes large, and the motor housing efficiency of the container is low. That is, since the container space per motor is large, a large number of containers are required, and a large space is required for storing the containers, which is disadvantageous in terms of container storage and cost.

(b) Since the volume of the container is the same whether the motor is not housed, that is, the box is empty, or the motor is housed, wasteful space is required to store the empty box.

(c) Styrofoam is more expensive than other packaging materials.

(d) It is difficult to know what to do when disposing of containers that are no longer needed. That is, even if it is crushed, its volume hardly changes, and it cannot be easily incinerated, so careless disposal will cause pollution problems.

The purpose of this invention is to solve the problems of conventional Styrofoam containers by using a container made of sheet-shaped synthetic resin. The weight of the motors is supported by the motors housed in the lower container to compensate for the strength of the sheet-like container, and the efficiency of housing the motors is high. The object of the present invention is to provide a micro-motor packaging container that requires less storage space and is also superior in terms of container manufacturing cost and transportation cost. below,
This will be explained with reference to the drawings.

FIG. 3 is a perspective view showing an embodiment of the micro motor packaging container of the present invention, and FIG.
FIG. 5 is a cross-sectional view showing the storage state of the container, and FIGS. 6A and 6B are plan views of the container, respectively, showing a state in which the orientation has been changed by 180 degrees. Reference numerals 1 to 3 in the figure correspond to those in FIG. 1, and a and b
represents a side of the container 1 forming an opposite side parallel to the axial direction of the motor 2. Note that the lower end position of the side edge is selected to be located below the lower end position of the deepest part of the motor accommodating recess 3, which will be described later.

The packaging container for the micro motor according to the present invention is formed by molding a sheet of synthetic resin (for example, hard vinyl chloride). As shown in FIG. 3, a motor accommodating recess 3 for accommodating a motor 2 is provided in the packaging container 1. If the shape of the motor housing recess 3 corresponds to the outer shape of the motor 2, and the depth of the recess 3 is approximately 1/3 of the outer diameter of the motor 2, the motor 2 can be accommodated without wobbling. I can do it. Further, a plurality of the recesses 3 are arranged in parallel, and a plurality of rows are formed of the plurality of recesses 3 arranged in parallel. By arranging the plurality of recesses 3 and the plurality of rows of recesses 3 in a staggered manner as shown in FIG.
By being located outside of the motor 2, the housing efficiency per unit area (planar) of the motor 2 can be increased.

The packaging container 1 in which the motor 2 is stored in each of the motor storage recesses 3 is stacked in multiple stages and stored in, for example, a cardboard box prepared in advance to match the size of the packaging container 1, and then packed. When stacking the packaging containers 1, if the motors 2 are staggered in the vertical direction as shown in FIG. 4, not only can the three-dimensional storage efficiency of the motors 2 be increased, but also the The upper part of the motor 2 is sandwiched between the two upper motors 2 to prevent it from wobbling, and also, as shown in FIG. It can be placed on the middle packaging container via the holder, resulting in a stable storage condition. In the case of a sheet-shaped container as in the case of the present invention, each layer of sheets does not have enough mechanical strength to support the weight of the motor, but by stacking the sheets as shown in Figure 4, In this way, the above-mentioned lack of strength is compensated for.
In order to obtain the state shown in FIG. 4, it is sufficient to simply change the orientation of the packaging container 1 by 180 degrees in a plane for each stage. That is, FIG. 6A showing the plan view of FIG.
FIG. 6B shows a state in which the illustrated packaging container 1 is turned 180 degrees in plan view. FIG. 6 shows an embodiment in which eight motor housing recesses 3 are arranged in parallel (horizontal direction in the figure) and five rows of the eight recesses 3 are arranged (vertical direction in the figure). It is shown. As a condition for achieving the state shown in FIG. 4, the number of columns in the vertical direction must be an odd number. Therefore, the packaging container 1 in the state shown in FIG. 6B is stacked on the packaging container 1 in the state shown in FIG. 6A (side side a in FIG. 6A and side b in FIG.
6A on top of that)
If the packaging containers 1 shown in the figure are stacked, the motors 2 will be arranged as shown in FIG.

In addition, by providing a plurality of ribs (not shown) in the recess 3 that accommodates the motor 2, the packaging container 1
This can serve as a reinforcement for the motor 2 and as a buffer to prevent damage to the motor 2 from impact. The shape of the ribs may be appropriately selected from a circular arc shape, a trapezoid shape, a triangular shape, or any other shape that is effective for the reinforcement and buffering effects.

Next, the storage condition of the packaging container 1 of the present invention will be explained. Generally, micro-motors are mass-produced, and packaging containers for micro-motors must be produced in even greater quantities and stored in large quantities, for example, in warehouses, until they are used. Therefore, it goes without saying that the smaller the storage space is, the better.

Fig. 5 shows the state of the packaging container 1 of the present invention during storage (Fig. 5 is, for example,
-Y′ cross-sectional view). When the packaging containers 1 of the present invention as shown in FIG. 3 are stacked and pressed in the same direction, that is, so that the sides a and b shown in FIG. Since they are made of synthetic resin such as vinyl and have flexibility, they can be stacked in close contact with each other as shown in FIG. Therefore,
The packaging container 1 requires only a small space during storage, and is particularly suitable for large-volume storage.

As explained above, according to the present invention, the packaging container for the micro motor is formed from a synthetic resin sheet and the motor housing recess is appropriately provided, thereby increasing the motor housing efficiency and improving the storage space of the packaging container. Furthermore, it is possible to provide a micro-motor packaging container that enables reductions in the manufacturing cost of the packaging container and the transportation cost of the motor.
