Description

  The present invention relates to an individual packaging box for individually packaging discharge lamps, and more particularly to an individual packaging box for a xenon discharge lamp in which high-pressure gas is enclosed in a glass arc tube.

In a short arc type discharge lamp used for a light source for a digital cinema or the like, a discharge gas such as xenon is enclosed in a glass arc tube at a pressure higher than atmospheric pressure.
Such a discharge lamp is basically safely transported, and the arc tube will not burst, but it is extremely dangerous if it breaks, so just in case it is transported in the lamp individual box. It is held in a cushioning material called a pad, packed and shipped.

For example, Japanese Unexamined Patent Application Publication No. 2002-370784 (Patent Document 1) describes a conventional example of this type of individual packaging box.
Fig.8 (a) is a perspective view which shows the individual packaging box concerning a prior art example. In this figure, an individual packaging box 80 is composed of an outer packaging box 81 made of corrugated paper and pads 82 arranged at both ends in the box.
FIG. 8B is a perspective view showing the pad. The pad 82 is formed by bending a piece of corrugated cardboard as shown in the figure, and has V-shaped support surface portions 89 and 89 and reinforcing surface portions 85 and 85 for holding the same.
With such a structure, the support surface portion 89 is reinforced by the reinforcing surface portion 85 while being slightly deformed in accordance with the shape of the lamp cap.
According to the present invention, even if the length of the lamp is long or short, it can be held correspondingly, and when discarding the individual packaging box, it is not necessary to separate the buffer material, and the assembly is simple. It was a thing.

However, the lamp weight has increased due to the increase in size of the lamp. In addition, overseas production and sales volumes are increasing, and even overseas, even if a cautionary note is placed on the outer surface of an individual packaging box during handling, it may be handled roughly. This causes a problem that the pad is deformed during transportation. If the pad is transported in a deformed state, there is nothing that reliably holds the lamp, which may cause damage.
Furthermore, the individual packaging box is transported not only in a state where the longitudinal direction is horizontally oriented as shown in the figure but also in a state where it is placed vertically from the viewpoint of efficiency. It is coming. Therefore, in the conventional pad, the holding in all directions is insufficient, and in particular, the holding in the longitudinal direction of the individual packaging box is insufficient.
