Description

[Detailed explanation of the idea] The present invention relates to a packaging container for tubes.

In general, in packaging containers for tubes, in particular,
It is important to protect the glass bulb, which is the contents of the tube, which is easily damaged.

Conventionally, for example, as a packaging container for a U-shaped fluorescent lamp, a protective object separate from the flat, rectangular cylindrical packaging container body was inserted inside the container along almost its entire length, and this protective object was used to protect glass bulbs, In particular, those that protect the head are known.

However, in such a packaging container, since the protective object is constructed separately from the packaging container body, the workability thereof is poor, and more materials are used, resulting in an increase in cost.

This invention has good assembly workability, requires less materials, and can reduce costs.
Furthermore, the present invention provides a packaging container for tubes that can sufficiently protect the tube contents from vibrations and impacts.

An embodiment thereof will be described below with reference to the drawings.

In FIG. 1, this packaging container for tubes is made of a piece of corrugated paper, and has a packaging container main body consisting of main surfaces 1, 2, side surfaces 3, 4, and an adhesive margin 5. As shown in FIG. 2, a rectangular cylindrical packaging container body 6 is made by adhering the packaging container body 6 with a folding piece 7, a tube protection piece 8, and a tube protection piece 8 at the open end of the packaging container body 6. A tongue piece 9 is provided in a row. The width of the folded piece 7 is smaller than the width of the main surface 2, the width of the tube protection piece 8 is almost equal to the width of the main surface 2, and the width of the tongue piece 9 is smaller than the width of the tube protection piece 8. Then, from the state shown in FIG. 2, the folded piece 7 is folded back inside the packaging container body 6, and the tube protection piece 8 is folded from this folded piece 7 so as to close the opening of the packaging container body 6. Furthermore, the tongue piece 9 is bent from the tube protection piece 8 toward the open end (see FIG. 3).

Furthermore, from the state shown in FIG. 3, notches 10 and 11 are diagonally provided in the corners of one end of the packaging container body 6, and cuts 12 and 13 are also provided diagonally in the corners of the other end. The support parts 14, 15 and the support parts 16, 17 are each pushed inward of the packaging container main body 6 along the fourth
As shown in the figure, the tube packaging container is assembled. At this time, the tube protection piece 8 is
It is supported from the outside.

In order to package, for example, a U-shaped fluorescent lamp 18 as shown in FIG. 5 using such a tube packaging container, the supporting portion 14 of the tube packaging container in the state shown in FIG. 15 inward, and insert a U consisting of a glass bulb 18a and a cap part 18b into it.
Insert the shaped fluorescent lamp 18, and then insert the support part 1.
6 and 17 in the same manner, the U-shaped fluorescent lamp 18 is housed in the bulb packaging container, as shown in FIGS. 6A, B and C. The head of the glass bulb 18a is in contact with the back surface of the bulb protection piece 8.

According to the above configuration, since the tube protection piece 8 is supported from the outside by the support parts 14 and 15, the tube protection piece 8 can be protected even if vibrations, shocks, etc. are applied during handling or transportation. 8 is firmly supported in a predetermined position without fear of it jumping out.
The U-shaped fluorescent lamp 18 therein is therefore well protected. Furthermore, since the open ends of the main surfaces 1 and 2 have a double structure by overlapping the folded pieces 7 and the tongue pieces 9, the mechanical strength is high. Therefore, even if the U-shaped fluorescent lamp 18 is accidentally dropped with the bulb protection piece 8 facing downward, the U-shaped fluorescent lamp 18 is sufficiently protected from impact. Furthermore, the tube protection piece 8 is
4 and 15, there is no need to use adhesive or stitches for fixing, and the structure is extremely simple. Since the packaging container main body 6 and the tube protection piece 8 are integrated,
Compared to conventional products, the material cost is lower, and assembly is easier and workability is better.

As explained above, the present invention is simple in structure and assembly, can sufficiently protect the tube contents from vibrations and shocks, and requires less material cost, resulting in major improvements such as cost reduction. Accordingly, it is possible to provide an effective tube packaging container.
