Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to an insulator packaging container.

[Prior Art] Conventionally, when packing suspension insulators 13 as shown in FIG. 5, a plurality of suspension insulators 13 were placed in a wooden box 20 to form a small unit packaging container. Furthermore, a plurality of these small-unit packaging containers were stacked on pallets and bundled.

[Problems to be Solved by the Invention] However, the wooden box 20 in which the suspended insulator 13 is packed tends to be handled relatively roughly by transport workers.

Therefore, there was a problem that the wooden box 20 was damaged or the suspension insulator 13 inside the wooden box 20 was damaged due to this impact.

In addition, the suspension insulators 13 are arranged in such a way that the ribs 11 are staggered, and additionally, auxiliary materials must be attached inside the wooden box 20 to securely fix the suspension insulators 13, resulting in poor workability. The problem was that it was expensive.

Furthermore, when a plurality of small unit packaging containers are stacked on pallets, the volumetric efficiency is poor because the outer surfaces of the wooden boxes 20 simply overlap.

An object of the present invention is to provide a packaging container that is highly workable, inexpensive, and has high volumetric efficiency.

[Means for Solving the Problems] In order to achieve the above object, the first invention of the present application provides four storage parts for insulator positioning inside the bottom wall and the side walls integrally formed on the outer periphery of the bottom wall. The gist is that it consists of a pair of packaging members, both of which are made of a cushioning material, and that the two packaging members are stacked on top of each other so that the insulator is stored between the two storage recesses.

The gist of the second invention is that the outer surfaces of the side walls of the pair of packaging members are provided with uneven portions that fit into each other when the respective packaging members are installed side by side so that the side walls of each packaging member are overlapped with each other. do.

The third invention provides that the outer surfaces of the bottom walls of the pair of packaging members are provided with uneven portions that fit into each other when the respective packaging members are installed side by side so that the bottom walls of each packaging member are overlapped with each other. This is the summary.

A fourth aspect of the present invention is to provide the outer surfaces of the side walls of the pair of packing members with uneven portions that fit into each other when the respective packing members are placed side by side so that the side walls of each packing member □ overlap each other, and further,
The gist is that the outer surfaces of the bottom walls of the pair of packaging members are provided with concavo-convex portions that fit into each other when the respective packaging members are placed side by side so that the bottom walls of each packaging member are overlapped with each other.

The gist of the fifth invention is that a plurality of rows of storage recesses for positioning the insulators are provided, a plurality of insulators can be stored in each row of storage recesses, and the insulators in the storage recesses adjacent to each other are arranged in a staggered manner. shall be.

[Function] When packing an insulator with both packing members, if the insulator is inserted into the storage recess of the negative packing member and then covered with the other packing member, the insulator will fit into the storage recess of both packing members. It is stored between the recesses. In this case, by providing a plurality of rows of storage recesses for positioning the insulators and making it possible to store a plurality of insulators in each row of storage recesses, the insulators in the storage recesses adjacent to each other can be stored in a staggered manner.

In addition, even if the packaging material is subjected to shock during transportation, *
The packaging member made of I material absorbs this shock, and the shock is not easily transmitted to the insulator.

Further, by fitting the uneven portions of the side wall or the bottom wall of each packing member to each other, or the uneven portions of the side wall and the bottom wall, the packing members can be stacked vertically and horizontally.

[Example] Hereinafter, an example in which the present invention is embodied in a packaging container for a suspended insulator will be described with reference to FIGS. 1 to 3.

As shown in FIG. 1, the styrofoam packaging container is composed of a pair of upper and lower packaging members 1.2. Second
As shown in the figure, three suspended insulators 13 are housed on the inner surface of both the upper and lower packaging members 1.2 by the bottom wall 3 and front, rear, left, and right side walls 4.5 integrally formed on the outer periphery of the bottom wall 3. Two rows of storage recesses 6 are provided with a partition wall 9 in between.

In each row of storage recesses 6, one suspension insulator 13 has a muscle portion 11.
The insulator storage section 7 that stores the insulator and the cap metal storage section 8 that stores the cap metal fitting 10 of one suspended insulator 13 are the same.
It is formed continuously in different directions. Note that the storage recesses 6 in both rows are oriented in opposite directions, and are formed such that the insulator storage portions 7 of one storage recess 6 are staggered between the two insulator storage portions 7 of the other storage recess 6. . A connecting pin housing part 14 for storing a connecting bin 12 of a suspended insulator 13 is formed inside the upper edge of both front and rear walls 5 adjacent to the insulator housing part 7 .

Further, the outer surfaces of the left and right side walls 4 and the outer surface of the bottom wall 3 of both the upper and lower packaging members 1.2 are provided with uneven portions 15a and 15b.

16a and 16b are alternately arranged in parallel in the front-rear direction. Among the uneven portions 15a, 15b, 16a, and 16b, the protruding portions 15b and 16b are provided at positions corresponding to the insulator storage portions 7 of the four storage portions 6, respectively.

A tape hooking groove 17 is continuously formed from the front and rear side walls 5 to the bottom wall 3 of both the upper and lower packaging members 1.2.

When the upper and lower packaging members 1 and 2 configured as described above overlap each other on their inner surfaces as shown in FIG. It has become.

In order to pack the suspension insulators 13 with these packing members 1 and 2, first, as shown in FIG. Each is inserted into the storage recess 6 of the lower packaging member 2. In this state, the cap metal fitting 10 of the suspension insulator 13 is inserted into the cap metal fitting storage part 8, the muscle part 11 is inserted into the insulator storage part 7, and the connecting pin 12 is inserted into the connection pin storage part 14, and the lower half of the suspension insulator 13 is inserted. The part matches the storage part 6.

As a result, the upper half of the suspension insulator 13 is exposed, and when the upper packaging member 1 is placed over the upper packaging member 1 as shown in FIG. is stored in. Thereafter, in order to prevent the upper and lower packing members 1.2 from separating and exposing the suspension insulator 13, the first
As shown by the two-dot chain line in the figure, attach the tape 18 to the tape hanging groove 1.
7 to secure both the upper and lower packaging members 1.2 to each other. When transporting and storing the suspended insulators 13, a plurality of packaging containers are stacked vertically and horizontally on a pallet as shown in FIG.

Particularly in this embodiment, shocks during packing work and transportation are absorbed by the y1 impact effect of the packing member 1.2, so that the packing container and the suspension insulator 13 inside thereof are less likely to be damaged.

In addition, the suspended insulator 13 can be
Unlike conventional packaging, auxiliary materials are not required and the number of parts is reduced, making packaging easier and faster, which not only improves work efficiency but also reduces packaging costs. .

Furthermore, since the storage recesses 6 are separated from each other by the partition wall 9, the striations 11 of the suspension insulators 13 will not rub against each other and be damaged.

Further, the insulator storage section 7, the cap metal fitting storage section 8, and the connecting pin storage section 14 of the storage recess 6 of both the upper and lower packaging members 1 and 2 are provided.
The suspension insulator 13 matches the muscle portion 11, the cap fitting 10, and the connecting bottle 12, so that the suspension insulator 13 does not wobble.

In addition, since the suspension insulator 13 is packed in a sealed manner, the suspension insulator 13 is not contaminated.

On the other hand, as shown in FIG. 3, when the packaging containers are stacked vertically and horizontally, the uneven portions 15a, 15b, 16a of the left and right side walls 4 and bottom wall 3 of both the upper and lower packaging members 1.2.

16b fit into each other. As a result, the stacking volume becomes smaller than in the past, reducing transportation costs and making it difficult for the packaging containers to collapse.

Although two rows of storage recesses 6 are provided in this embodiment,
As shown in FIG. 4, it is also possible to provide the packaging member 1.2 with storage recesses 6 arranged in a row and with an increased number of storage insulators 13.

In this example, both the upper and lower packaging members 1 and 2 were molded from expanded polystyrene, but molded pulp, cork,
It is also possible to mold it from synthetic rubber or the like. Further, although the present invention is embodied in a packaging container for the suspended insulator 13, it is also applicable to packaging containers such as pin insulators.

[Effects of the Invention] As detailed above, in the present invention, since the insulator is packed using a packaging member having WI properties, the packaging container absorbs the WI impact and the insulator is less likely to be damaged. . Also,
Since insulators can be packaged using only the upper and lower packing members, there is no need for auxiliary materials compared to the conventional method, and the number of parts is reduced, making the packing process easier and faster, which not only improves work efficiency. Packing costs can also be reduced.

Furthermore, in the present invention, when the packaging containers are stacked vertically and horizontally, the uneven portions on the side walls or the uneven portions on the bottom wall or the uneven portions on the side wall and the bottom wall of both the upper and lower packing members fit together, so that the stacking volume is small. At the same time, the load becomes less likely to dislodge.

Furthermore, when the insulators in the storage recesses adjacent to each other are stored in a staggered manner, the volumetric efficiency is increased.
