Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a packaging material for packaging morning glory-shaped ceramics such as ferrite cores for television deflection yokes (hereinafter referred to as ferrite cores).

Conventionally, there have been packaging materials of this type as shown in FIGS. 1 and 2. That is, FIG. 1 shows a conventional foamed polystyrene packaging material, which has drawbacks such as high cost and unavoidable pollution problems when disposed of. Figure 1 shows a conventional cardboard packaging material with a stiffener S on the side of the packaging material body.
Although the material cost is low, tools such as the above-mentioned Stiffener S or glue are required during assembly, and since the packaging material inevitably bends in such a configuration, the ferrite core inside the packaging shape However, there was a drawback that the fixation and holding tended to lack stability, resulting in a lack of reliability.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional ones, and by providing a pair of insertion tongues protruding from both ends of a single plate and drilling an insertion hole in the center, The purpose of the present invention is to provide a packaging material for morning glory-shaped ceramics that is easy to assemble without requiring tools and can maintain and fix its shape.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is an opening of a packaging material showing an embodiment of the present invention, and FIG. 4 is an assembly diagram of FIG. Two insertion tongues are formed in each side in a symmetrical protruding shape, and reference numeral 3 is an insertion hole drilled in the center of the plate 1 corresponding to the insertion tongue 2.

In the above configuration, the packaging material according to one embodiment of the present invention includes one plate 1 and an insertion tongue 2 as shown in FIG.
The mutually parallel bending lines a, b, and c at predetermined locations are sequentially bent at right angles so as to wrap inward, and the pair of insert tongues 2 are overlapped to form a pillar-like body, and this is inserted into the upper surface from the inside. It is inserted into the insertion hole 3 located in the hole 3 to form an assembled structure, thereby making it possible to easily package a morning glory-shaped ceramic such as a ferrite core and to hold and fix it in a highly reliable state.

As described above, according to the present invention, the insertion tongue and the insertion hole are integrally formed in the plate-shaped packaging material, and the structure has a desired shape that can be assembled after folding. (1) Stitching during assembly. There is no need for tools such as glue or glue, and it can be easily assembled by folding and inserting.

(2) Since the insertion part becomes a support, the reliability of fixing and holding the ferrite core is improved.

(3) Cardboard, which is an inexpensive material, can be used.

You can get great benefits such as:

Claims (1)

[Claims] (1) One board has an insertion hole in the center, vertical bending straight lines parallel to each other at symmetrical positions on both sides, and insertion tongues forming a pair at both ends of the insertion hole. It has a structure in which each bending straight line is sequentially bent at right angles so as to be rolled inward, and the pair of insertion tongues are overlapped with each other to form a pillar-like body, which is then inserted into the insertion hole upward from the inside.
