Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging box for an annular fluorescent lamp.

[Conventional technology]

Conventionally, as shown in FIG. 1, packaging boxes for individual packaging of annular fluorescent lamps have been designed to correspond to the ring outer diameter and tube outer diameter of the annular fluorescent lamp 1 so that the upper end surface 4a can be opened and closed. It was made of cardboard folded and fixed. Furthermore, a certain number of these packaging boxes were collected and stored in a large box (not shown) for distribution.

However, since the packaging box is made of cardboard, it cannot be denied that the cost is high, and in recent years, attempts have been made to reduce the cost by replacing the material of the packaging box from cardboard to paperboard. Jitsukai Showa 53-
Publication No. 6769 shows a typical example of a packaging box for an annular fluorescent lamp using paperboard, and in order to compensate for the lack of cushioning effect when paperboard is used, the four corners of the joint between the bottom plate and the top plate are A configuration has been proposed in which the corners are formed into edge-like protrusions.

[Problem that the invention attempts to solve]

However, the packaging box shown in the above-mentioned Japanese Utility Model Publication No. 53-6769 does not have any measures against the impact force applied in the direction of the surface of the lamp, and has the problem that the impact resistance is lower than that of cardboard products. Because they protrude outward from the packaging box, the size of the large box that stores a certain number of packaging boxes increases, resulting in poor transportation and storage efficiency and an increase in the amount of packaging material used for the large box. It had problems such as:

The present invention aims to provide a packaging box for an annular fluorescent lamp that can reduce the cost of the packaging box without reducing the buffering effect, as well as reduce the logistics costs required for transportation and storage.

[Means for solving problems]

The packaging box for the annular fluorescent lamp according to the present invention is
A box made of paperboard is provided with a protrusion on each side that comes into contact with the annular fluorescent lamp housed in the box, and this protrusion is formed by pressing a plurality of linear protrusions that do not intersect with each other. This is what I did.

[Effect]

In the present invention, the protrusion is adapted to abut the annular fluorescent lamp in the outer radial direction (on the lamp surface side) and in the outer radial direction (in the circumferential direction of the ring). Therefore, the annular fluorescent lamp housed in the packaging box is supported by the protrusions formed on each side and end surface without directly coming into contact with those plate surfaces. Now, even if an external force such as a drop impact is applied to the packaging box from any direction, the protrusion acts as a buffer member, thereby preventing the lamp from being damaged. Furthermore, since the protrusions are straight lines that do not intersect with each other, when press-forming the protrusions, it is possible to prevent the paperboard from tearing at the intersection points, and to facilitate the production of the mold. Furthermore, since the protrusions protrude inward from the packaging box, there is no need to change the shape of the packaging box, as shown in Figure 1, which prevents the size of the large box from increasing and reduces logistics costs. suppress.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 2 to 4.

FIG. 2 is a developed view of the packaging box according to the present invention. That is, punch out a piece of paperboard (for example, the white ball described in "New Packaging Technology Handbook" edited by the Japan Packaging Technology Association, Japan Productivity Center, December 10, 1972, p. 223) to form the bottom surface. Side surfaces 3a and 3b are provided that are connected to each other by gable surfaces 4b, and gable surfaces 4 are provided on the left and right sides of these side surfaces 3a and 3b, respectively, and a sealing portion 6 is connected to the tip of one side surface 3a. A gable surface 4a forming an upper surface is provided. Then, in this packaging box, there is 1 annular fluorescent lamp.
When the annular fluorescent lamp 1 is stored, the ring surface of the annular fluorescent lamp 1 is placed on the side surfaces 3a, 3b, and the end surfaces 4a, 4b, 4
The outer diameter portions of the two come to face each other. In such a device, the present invention provides a projection 5 formed by a press mold or the like on the inner surface of each side surface 3a, 3b and each end surface 4a, 4b, 4 that abuts the annular fluorescent lamp 1.
A plurality of these are installed in a straight line that does not intersect with each other in the inward direction of the box. Specifically, among the projections 5, eight are provided on the side surfaces 3a and 3b radially from the center of the surface, and eight are provided on the end surface 4.
The ones provided at a, 4b, and 4 are arranged in parallel and facing each other. Then, this paperboard is bent so that the respective end surfaces 4 of each side surface 3a and 3b are overlapped, and the overlapping portion is fixed with adhesive or the like, and the third
It is formed into a packaging box as shown in the figure.

In addition, eight projections 5 are formed radially on the side surfaces 3a and 3b as shown in FIG.
The invention is not limited to forming three pieces on each of 4b and 4.

As described above, according to the present invention, on each side and each end of the packaging box for an annular fluorescent lamp made of paperboard,
A plurality of linear protrusions are formed by pressing and contact the fluorescent lamps stored in the packaging box, and do not intersect with each other, thereby improving the protection of the stored items. Moreover, it is possible to prevent the box material from being torn during the process of manufacturing the box, and to facilitate the manufacture of the mold for forming the protrusions. Furthermore, since the dimensions of the packaging box can be reduced, the dimensions of the large box can also be reduced, which in turn improves transportation and storage efficiency, making it possible to reduce logistics costs. We can provide packaging boxes.
