SOLUTION: Steps 2a-2d, 3a-3c, 4a-4c and 5a-5c are formed at the peripheries of rising walls 2-5 on four sides of a square container having at its inside a plurality of housing parts for housing component parts, and the steps on the opposite sides are positioned, being offset sideways.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a packaging container for electronic parts and the like.

[0002]

2. Description of the Related Art In order to store electronic parts in a large box in a state where they are stacked vertically, the electronic parts are planted in a cushioning material using their terminals, and another cushioning material is laminated above them. By doing so, it was made into a polymer and stored in this state in a large box.

[0003]

With the above-mentioned structure, a load from above may be applied to the lower electronic component, which may be damaged.

Therefore, the present invention has an object to prevent damage to a housing for electronic parts and the like below.

[0005]

In order to achieve this object, the present invention is directed to four sides of the outer periphery of a rectangular container having an upright wall on the outer periphery and a plurality of component storage portions inside. Steps are formed on the outer peripheral surface of the standing wall, and the steps on the opposite sides are offset laterally, thereby achieving the intended purpose.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the invention of claim 1 of the present invention, a rectangular container having a standing wall on the outer peripheral portion and a plurality of component storage parts on the inner side is provided on the outer peripheral surface of the standing wall on the four sides of the outer periphery. Respectively form step portions, and the step portions on the opposite sides are laterally offset.

With the above construction, after the parts are housed in the packaging containers of the same shape, the packaging containers to be stacked on top are simply rotated by 180 degrees to be stacked, and the steps on the four sides of the upper side are the standing walls on the bottom. Since it is placed on the upper side, the load in the lower packaging container from the upper packaging container is not applied and the damage is not caused.

According to a second aspect of the present invention, the component storage portion includes a component support portion and terminal storage portions which are concave downwards on both sides thereof, and the step portion is equivalent to the terminal storage portion. The packaging container according to claim 1 provided below the packaging container, and a sufficient storage space is formed in the packaging container below the terminal storage portion of the upper packaging container.

Further, according to the invention of claim 3 of the present invention, the packaging container according to claim 2 wherein a recess for reinforcement is provided in the component supporting portion, and the bottom surface of the recess is provided above the bottom surface of the terminal accommodating portion. Therefore, when the packaging container is formed by the vacuum forming method, since the bottom of the reinforcing recess is not pulled downward, the wall thickness can be held thick and the reinforcing force becomes high.

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a polyethylene terephthalate packaging container, in which standing walls 2 to 5 are provided on the outer peripheral four sides, and a plurality of component storage portions 6 are provided inside thereof.

Each standing wall 2-5 is provided with a plurality of steps 2a-2d, 3a-3c, 4a-4c, 5a-5c, respectively, but the steps on opposite sides, for example, 2a and 4a.
Positions c, 3a and 5c are laterally offset.

In addition, the component storage section 6 has a board-shaped electronic component 7
Is to be stored. The electronic component 7 has terminals 7a bent downward on both sides thereof.
a is accommodated in the terminal accommodating portion 6a which is concave downward as shown in FIGS. 1, 3 and 4, and in that state, the component supporting portion 6a is accommodated.
supported on b. Further, as shown in FIG. 4, a reinforcement recess 6c is provided between the component support portions 6b.

Now, FIG. 2 shows the same packaging container 1 as in FIG. 1, but it is in a state rotated by 180 degrees. When the packaging container 1 of FIG. 1 is polymerized on the packaging container 1 of FIG. 2 in this state, the states shown in FIGS. 3 and 4 are obtained. As is apparent from FIGS. 3 and 4, since the facing step portions are laterally displaced as described above, the upper and lower step portions do not overlap in the vertical direction in the overlapped state, and the upper step portion does not overlap. Vertical walls 2 to 5 of the lower packaging container 1
It will be placed on the upper side as shown in FIG. This figure 4
Using the steps 2a to 2d, 3a to 3c, 4a to 4c, 5
The heights of a to 5c, the terminal accommodating portion 6a, and the reinforcing concave portion 6c will be described. Since the step portion is equal to or lower than the terminal accommodating portion 6a, the height below the upper terminal accommodating portion 6a. Has a sufficient storage space, and therefore the lower packaging container 1
The load from above is not applied to the electronic component 7 inside,
Damage is prevented.

The bottom of the recess 6c for reinforcement is set to be higher than the bottom of the terminal accommodating portion 6a by extending the bottom of the recess 6c downward when the packaging container 1 is formed by the vacuum forming method. To keep the wall thickness thin,
Sufficient wall thickness is secured and a large reinforcing force is obtained.

[0015]

As described above, according to the present invention, in a rectangular container having a standing wall on the outer peripheral portion and a plurality of component storage parts inside, a step portion is provided on each of the outer peripheral surfaces of the standing walls on the four sides of the outer periphery. And the steps on the opposite side are offset to the side,
With the above configuration, after the parts are stored in the packaging containers of the same shape, the packaging container to be stacked on top is simply rotated by 180 degrees and stacked, and the step portions on the four upper sides are mounted on the lower standing wall. As a result, the items stored in the lower packaging container are not loaded by the upper packaging container and are not damaged.
