Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a packaging container for a straight tube fluorescent lamp.

Conventional Structure and Problems Conventionally, for packaging containers for straight tube fluorescent lamps of this type, a notch is provided in the circumferential direction in the main body of the packaging container in the shape of a square tube, and a cut is made in the circumferential direction from both ends of this notch in a direction perpendicular to this. A structure is known in which a folding line extending toward the opening end of the packaging container main body is provided to constitute a folding piece that is a holding piece for a straight tube fluorescent lamp, and the folding piece is folded inward from the folding line. (For example, 1986-
35385, Utility Model Application Publication No. 59-80287).

However, in a packaging container with such a structure, during transportation, handling, etc., when an external impact is applied to the folded piece of the packaging container itself, or when the same impact is applied to the packaging container and the product is stored inside it. There has been a problem in that when the straight tube fluorescent lamp is moved, the folded piece returns to its original state relatively easily, and as a result, the holding function of the straight tube fluorescent lamp is lost.

Purpose of the Invention The present invention provides a packaging container for a straight tube fluorescent lamp that has a simple structure and can securely hold a straight tube fluorescent lamp stored therein without the risk of the holding piece returning to its original state. This is what we provide.

Structure of the Invention The present invention provides a first notch that crosses the ridge in a part of the circumferential direction of a square cylindrical packaging container body, and extends from both ends of the first notch along the ridge near the first notch. A second notch is provided toward the opening end side of the packaging container main body, and a fold line is provided extending from the second notch toward the opening end side of the packaging container main body and whose extension line intersects at the ridge. 1
A folding piece is formed by the cut, the second cut, and the folding line, and the folding piece is folded inward from the folding line so that the ridge located on the folding piece becomes a trough. The present invention is characterized by a packaging container for a straight tube fluorescent lamp, and this structure prevents the folded piece from returning to its original state.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a main part of a packaging container for a straight fluorescent lamp according to an embodiment of the present invention, and FIG. 2 is a developed view thereof.

1 and 2 show an example of a packaging container for simultaneously housing two straight tube fluorescent lamps.
As shown in FIG. 1, this packaging container is made of a piece of thick paper such as cardboard, and has a first cut 3 that crosses the edge 2 in a part of the circumferential direction of the packaging container main body 1 in the shape of a square tube.
A second notch 5 is provided along the edge 2 from both ends of the first notch 3 toward the opening end 4 of the packaging container body that is closer to the first notch 3.
A fold line 6 is provided that extends from the second cut 5 toward the opening end 4 side of the packaging container main body and whose extension line intersects at the edge 2. The first cut 3, the second cut 5, and the fold line 6 constitute a folded piece 7 (see FIG. 2). Then, the folding piece 7 is folded inward from the folding line 6 so that the edge located on the folding piece 7 becomes a trough.

As shown in FIG. 2, two folding pieces 7 are provided at both ends of the packaging container body 1. In the figure, 8 is the upper surface, 9 is the lower surface, 10 and 11 are the side surfaces, 12 is a piece to be glued to the inner surface of the upper surface 8, and 1
3 indicates a partition piece, 14 indicates a gluing margin, and 15 indicates a folding line.

3 and 4 show the straight tube fluorescent lamp housed in the packaging container, FIG. 3 is a view of the packaging container main body as viewed from the open end side, and FIG. 4 is a view of the packaging container main body. It is a diagram seen from the front. In FIGS. 3 and 4, 16 is a straight tube fluorescent lamp, 17 is a glass tube, 18 is a base, and 19 is a pin.

As described above, in this packaging container, after inserting the straight tube fluorescent lamp 16 into the packaging container main body 1, the folding piece 7 formed by the first cut 3, the second cut 5 and the fold line 6 is wrapped. Each end of the straight tube fluorescent lamp 15 is held by these folded pieces 7 which are sequentially folded into a valley shape inside the container body 1 . Therefore, even if an external impact is applied to the packaging container, there is no fear that the folding piece 7 will return to its original state. Therefore, the straight tube fluorescent lamp 16 housed in the packaging container is securely held by the folding piece 7. Also, according to this configuration,
Since a portion of the end of the straight tube fluorescent lamp 16 is covered by the folded piece 7, its holding becomes even more reliable.

In the above embodiments, the case where two straight tube fluorescent lamps are used has been described, but it goes without saying that the present invention can also be implemented in cases where one lamp is used.

FIGS. 5 and 6 show an example of a packaging container containing one straight tube fluorescent lamp, and in this case as well, the same effects as in the above embodiment are achieved. In addition,
In Figures 5 and 6, Figures 1 and 2
Portions corresponding to those in the figures are designated by the same numbers.

Effects of the Invention As explained above, in the packaging container for a straight tube fluorescent lamp of the present invention, a first notch is provided in a part of the circumferential direction of the packaging container main body in the shape of a square tube, and the first cut is provided in a part of the packaging container main body in the circumferential direction. A second notch is provided along the ridge from both ends of the notch toward the opening end of the packaging container body that is closer to the first notch, and a second notch is provided extending from the second notch toward the opening end of the packaging container body. and a fold line whose extension line intersects at the edge is provided, the first cut, the second cut and the fold line constitute a fold piece, and the edge located on the fold piece becomes a trough, The folding piece is folded inward of the packaging container body from the fold line,
Therefore, there is no fear that the folded piece will return to its original state due to an external impact, and the straight tube fluorescent lamp can be held securely. In addition, the folding piece is made up of only cuts and folding lines, and it is only necessary to fold it inside the packaging container body, so the structure is simpler and less complicated than conventional ones.
There is no increase in assembly man-hours and workability is good.
