Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an improvement of an individual case for a straight tube fluorescent lamp.

[Prior art] Generally, this type of individual packaging case is shown in Figs.
As shown in the figure, a rectangular tube-shaped case body A is formed from corrugated paper and cut so that its total length is the same as or slightly longer than the total length of a straight tube fluorescent lamp B. There is.

[Problems to be solved by the invention] By the way, the inner dimensions C of all the walls of the case body A are designed to facilitate automatic insertion of the straight tube fluorescent lamp B into the case body A. Since the diameter is set to be slightly larger than the outer diameter D of the lamp B, the ability of the case body A to hold the straight tube fluorescent lamp B tends to decrease.

Therefore, for example, when the case body A is placed in a vertical position as shown in FIG. 3 during handling, there is a drawback that the straight tube fluorescent lamp B easily falls out of the case body A and is easily damaged.

Therefore, the purpose of the present invention is to improve the retention of the straight tube fluorescent lamp in the case body without impairing the ease of inserting the straight tube fluorescent lamp into the case body through a simple structure. We provide individual packaging cases.

[Means for solving the problem] Therefore, in order to achieve the above-mentioned objective, the present proposal is as follows:
A square cylindrical case body is formed from packaging material, and a plurality of elongated slits resembling perforations are intermittently formed in the longitudinal direction of the wall surface of the case body excluding both ends, and the inner dimension C of the case body is set to be approximately the same as the outer diameter D of the straight tube fluorescent lamp.

[Example] In FIGS. 4 to 6, 1 is a case body made of packaging material such as cardboard and formed into a rectangular tube shape. Excluding the parts 1a and 1b, there are three elongated slits 6 like perforations in the longitudinal direction in the widthwise center part.
This is formed intermittently. The inner dimension C of the case body 1 is set to be approximately the same as the outer diameter D of the straight tube fluorescent lamp 7.

In this way, the wall surfaces 2, 3,
4 and 5 have perforation-like elongated slits 6 formed in the longitudinal direction of the case body 1, so when inserting the straight tube fluorescent lamp 7 into the case body 1, the case body of the straight tube fluorescent lamp 7 1 wall 2, 3,
Frictional resistance to 4 and 5 can be reduced. However, if the slit 6 is formed perpendicularly to the longitudinal direction, the straight tube fluorescent lamp 7 will be caught in the slit 6 when the straight tube fluorescent lamp 7 is inserted into the case body 1. Not only will the performance be significantly impaired, but the case body 1 will also be easily damaged.

Furthermore, since the slits 6 are formed in the wall surfaces 2, 3, 4, and 5 of the case body 1 excluding both ends 1a and 1b, the inner dimension C of the case body 1 is the outer diameter D of the straight tube fluorescent lamp 7. Even if the setting is the same as that of the slit 6, when inserting the straight tube fluorescent lamp 7 into the case body 1,
5) is easily pushed outward. For this reason, most of the frictional resistance that acts on the straight tube fluorescent lamp 7 during insertion is specified from the end 1a (or 1b) of either one (insertion side) of the case body 1, which improves insertability. If it is in good condition, it can be shown.

Further, the slit 6 is formed at both ends 1a of the case body 1,
Since it is formed on the wall surfaces 2, 3, 4, and 5 except for 1b, the strength of the case body 1 is not impaired. Therefore, the straight tube fluorescent lamp 7 is attached to the case body 1.
It is possible to effectively prevent damage to the case body 1 when the case body 1 is inserted into or removed from the case.

Furthermore, since the inner dimension C of both ends 1a and 1b of the case body 1 is set to be approximately the same as the outer diameter D of the straight tube fluorescent lamp 7, it is possible to maintain good retention for the straight tube fluorescent lamp 7. can. Therefore, the straight tube fluorescent lamp 7 will not fall out of the case body 1 during handling. In particular, the wall surfaces 2, 3, 4, and 5 on which the slits 6 are formed are expanded when the straight tube fluorescent lamp 7 is inserted, so they are larger than the straight tube fluorescent lamps compared to both ends 1a and 1b of the case body 1. Although the retention performance for No. 7 is inferior, the slit-forming portion is long and contributes sufficiently to the retention performance.

In addition, in the present invention, the slits can be formed not only on all the wall surfaces, but also only on a specific wall surface, and the number of slits can be other than three. Further, the formation location thereof may be other than the center portion in the width direction of the wall surface.

[Effects of the present invention] As described above, according to the present invention, the simple structure improves the ability of the case body to hold the straight tube fluorescent lamp without impairing the insertability of the straight tube fluorescent lamp into the case body. can be effectively improved.
