Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an insulator packaging container.

[Prior Art] Conventionally, when packaging the suspension insulator 13 as shown in FIG. 5, a plurality of suspension insulators 13 are put in a wooden box 20 to form a small unit packaging container. Furthermore, a plurality of these small unit packaging containers are stacked on a pallet to bind them together.

[Problems to be Solved by the Invention] However, the wooden box 20 in which the suspension insulator 13 is packed has been apt to be handled roughly roughly by a transport worker. Therefore, there is a problem that the impact causes damage to the wooden box 20 and damage to the suspension insulator 13 in the wooden box 20. Further, the suspension insulators 13 are arranged so that the cap portions 11 are interleaved with each other, and furthermore, auxiliary materials must be attached inside the wooden box 20 to securely fix the suspension insulators 13, so that workability is poor. There was the problem of becoming expensive.

Furthermore, when a plurality of wooden boxes 20 in which the suspension insulator 13 is packed are stacked on a pallet, the outer surfaces of the wooden boxes 20 are simply overlapped with each other, so that the load easily collapses due to an impact from the outside, It became bulky and the volume efficiency when stacking was not good.

[Means for Solving the Problems] Therefore, in order to solve the above problems, the present invention provides a packing container including a pair of packing members that are made of a cushioning material and are polymerized with each other. The large-diameter storage portion and the small-diameter storage portion are provided with concavo-convex storage recesses that are continuous on the same axis, and the outer surface of the side wall and the outer surface of the bottom wall of each of the packing members are fitted at positions corresponding to the small-diameter storage portion. The recess was cut out, and a fitting protrusion capable of fitting with a fitting recess of another packaging container of the same shape was provided at a position corresponding to the large-diameter storage portion.

[Operation] That is, after the insulator is inserted into the storage recess of one of the packing members, the other packing member is superposed on the one packing member to be packed and housed in the packing container.

Further, when an impact is applied from the outside to the packaging container in which the insulator is packaged, the impact force is absorbed by the packaging member made of the cushioning material.

Further, when a plurality of packing containers in the packed state are stacked on a pallet, each packing container has a fitting concave portion and a fitting convex portion on the outer surface of the packing member which are formed in the same shape and are adjacent to each other. Fitting and locking to the fitting projections and fitting recesses provided on the outer surface to prevent collapse of the load, and each insulator housed in both adjacent packaging containers fits into the fitting recess. By fitting and locking with the convex portions, they are housed in different packaging containers and are in an intricately interdigitated state, and the stacking volume becomes smaller accordingly.

[Embodiment] An embodiment in which the present invention is embodied in a packaging container for a suspension insulator will be described below with reference to Figs.

As shown in FIG. 1, the styrofoam packing container is composed of a pair of upper and lower packing members 1 and 2. Second
As shown in the figure, on the inner surface side of the upper and lower packing members 1 and 2, three suspension insulators 13 are housed by a bottom wall 3 and front, rear, left and right side walls 4,5 integrally formed on the outer periphery thereof. Two rows of storage recesses 6 are provided via a partition wall 9.

In the storage recesses 6 of each row, an insulator storage portion 7 as a large diameter storage portion into which the cap portion 11 of one suspension insulator 13 is inserted, and a cap as a small diameter storage portion into which the cap metal fitting 10 is also inserted. The metal fitting housing 8 is formed continuously in the same direction. It should be noted that the storage recesses 6 in both rows are opposite to each other, and the insulator storage portions 7 of one storage recess 6 are formed so as to interleave between the insulator storage portions 7 of the other storage recess 6. . Both front and rear walls 5 adjacent to the insulator storage portion 7
On the inner side of the upper edge, a connecting pin housing portion 14 for housing the connecting pin 12 of the suspension insulator 13 is formed.

Further, as shown in FIGS. 1 and 2, on the outer surfaces of the left and right side walls 4 of the upper and lower packing members 1 and 2 and the outer surface of the bottom wall 3, respective positions corresponding to the cap metal fitting housing portion 8 of the housing recess 6 are provided. In, the fitting recesses 15a and 16a are notched so as to interlock with the insulator storage portion 7 of the storage recess 6 in a staggered manner. On the outer surface of each of the upper and lower packing members 1 and 2, the fitting convex portion 1 that can be fitted into the fitting concave portions 15a and 16a is located at a position corresponding to the insulator housing portion 7.
It is said to be 5b and 16b.

Tape hooking grooves 17 are continuously formed from both front and rear side walls 5 of the upper and lower packing members 1 and 2 to the bottom wall 3.

When the upper and lower packing members 1 and 2 configured as described above overlap each other on the inner surface side thereof as shown in FIG. 1, the storage recess 6 and the fitting concave and convex portions 15a and 15b of the left and right side walls 4 are aligned. It is like this.

Then, in order to package the suspension insulator 13 with both of the packing members 1 and 2, first, as shown in FIG. 2, a set of three suspension insulators 13 connected to each other by the connecting pin 12 to the cap fitting 10 is used. Each of them is fitted into the storage recess 6 of the lower packing member 2. In this state, the cap metal fitting 10 of the suspension insulator 13 is inserted into the cap metal fitting storage portion 8, the cap portion 11 is inserted into the insulator storage portion 7, and the connecting pin 12 is inserted into the connecting pin storage portion 14, respectively, and the lower half of the suspension insulator 13 is inserted. The part matches the storage recess 6.

As a result, the upper half of the suspension insulator 13 is exposed, and when the upper packing member 1 is covered in this state as shown in FIG. 1, each suspension insulator 13 is placed between the storage recesses 6 of both packing members 1 and 2. Is stored in. After that, in order to prevent the upper and lower packing members 1 and 2 from separating and the suspension insulator 13 from being exposed, as shown by the chain double-dashed line in FIG. Fix 1 and 2 to each other. And the suspension insulator 1
As shown in FIG. 3, when the 3 is transported and stored, as shown in FIG. 3, the fitting recesses 15a and 16a and the fitting projections 15b and 16b on the outer surfaces of the packing members 1 and 2 are vertically and horizontally adjacent to each other. The fitting protrusions 15b and 16b and the fitting recess 15 provided on the outer surfaces of the packing members 1 and 2 of the packing container
A plurality of pieces are stacked on the pallet while being fitted and locked to the a and 16a.

In particular, in this embodiment, the shock during the packing work and the transportation is absorbed and absorbed by the cushioning effect of the packing members 1 and 2,
In addition, the fitting concavo-convex parts that are adjacent to each other when the packaging containers are joined
Since 15a, 15b, 16a, 16b disperse and hold the load of the suspension insulator 13 with respect to each other, the packaging container and the suspension insulator 13 inside thereof are less likely to be damaged.

Further, since the suspension insulator 13 can be packed only by the upper and lower packing members 1 and 2, unlike the conventional case, no auxiliary material is required, the number of parts is small, and the packing work can be performed easily and in a short time. Not only can it be improved, but packaging costs can be reduced.

Further, since the storage recesses 6 are separated by the partition wall 9, the cap portions 11 of the suspension insulators 13 do not rub against each other and get damaged.

Further, the insulator housing 7, the cap fitting housing 8, and the connecting pin housing 14 of the housing recesses 6 of the upper and lower packing members 1, 2 are the cap portion 11 of the suspension insulator 13, the cap fitting 10, and the connecting pin 12.
The suspended insulator 13 does not rattle in conformity with.

Since the suspension insulator 13 is packed so as to be hermetically sealed, the suspension insulator 13 does not become dirty.

On the other hand, as shown in FIG. 3, when the packaging containers are stacked vertically and horizontally, the fitting concavo-convex portions 15a, 15b, 16a, 16b of the left and right side walls 4 of the upper and lower packing members 1 and 2 and the bottom wall 3 are fitted to each other. To do. As a result, the stacking volume is smaller and the bulkiness is not higher than in the conventional case, so that the transportation cost can be reduced and the packing container is less likely to collapse.

Although the storage recesses 6 are provided in two rows in this embodiment, it is also possible to provide the storage recesses 6 in one row in the packing members 1 and 2 and increase the number of suspension insulators 13 to be stored, as shown in FIG. Is.

In the present embodiment, the upper and lower packing members 1 and 2 were molded with expanded polystyrene, but in addition to this, mold pulp, cork,
It is also possible to mold with synthetic rubber or the like. Further, although it is embodied as a packaging container for the suspension insulator 13, it can be applied to a packaging container such as a pin insulator.

[Effects of the Invention] As described above in detail, in the present invention, the insulator is packed by using the packing member having the cushioning property, so that the packaging container absorbs the impact and is less likely to be damaged. Also, since the insulator can be packed with only a pair of packing members, unlike the conventional case, no auxiliary material is required, the number of parts is reduced, and the packing work can be performed easily and in a short time, and not only the workability is improved. The packing cost can be reduced.

Further, when a plurality of the packaging containers in the packed state are stacked, the fitting convex portion and the fitting convex portion provided on the outer surface of the packaging member of the other packaging container in which the fitting concave portion and the fitting convex portion of the outer surface of the packaging member are adjacent to each other. Since it is fitted and locked in the fitting recess, it is possible to reliably prevent the collapse of loads by the fitting and locking structure, and each insulator in both adjacent packing containers is stored in separate packing containers. It is possible to make a stacking state in which the layers are stacked in a staggered manner while being in a state, and the stacking volume can be reduced accordingly, and the volumetric efficiency can be improved.
