Description

[Detailed Description of the Invention] The present invention relates to a packaging case for fluorescent lamps and the like that are easily damaged by shock.The purpose of the present invention is to reduce the shock without using a special cushioning member and to have a simple structure. Our goal is to provide inexpensive packaging cases.

Conventionally, fluorescent lamps, which are easily damaged by impact, have been stored or transported in packaging cases made of cardboard, as shown in Figures 1 and 2. In conventional cases like this, the packaging case (
l)′ has a large buffering effect at the four corners, but the case side thI(
In the center of the case (1a), the fluorescent lamp (2)' is only protected by the cushioning effect in the thickness direction of the cardboard that forms the packaging case (1), and the fluorescent lamp (2) is not sufficiently protected. In other words, the collection,
When handling, if the case side C1m) is dropped so that it is parallel to the floor, or if the lighting equipment and fluorescent lamp (2)' are packaged together and transported, the case side C1m) (\1) and the side of the lighting fixture body, a large impact as shown by arrow F in the figure may be applied to the center of the case side (1 m), and the 91 fluorescent lamp (2)' may be damaged. was there. In order to prevent such inconveniences, it would be sufficient to arrange a cushioning material in the center of the case side 1fi (la), but this often has the drawbacks of complicating the structure and increasing cost. The present invention has been made in view of the above points.Examples will be described below with reference to the drawings. 4 to 6 show an embodiment of the present invention, and the embodiment shows a packaging case (1) for a U-shaped fluorescent lamp (2) as shown in FIG. The packaging case (1) is formed by punching cardboard paper into the shape shown in Figure 6 and folding it along the dotted lines. 3b)' is a pair of notches, which are formed over the entire length of the case side surface ('la) in the vertical direction and straddle the case upper surface (lb) 4 or the case lower surface (1c). However, in the example, notches (3b)' and (3a)
Case III surface portion is common. The strip-shaped parts (4m) (4b) formed between the cuts (3a), (3b) or (3aγ(3b)') are formed by bending the central part outward at an acute angle. Folded F!$(5a
) (sb) protrudes from the side of the case and has a V-shaped loose 9f1
(6m) (6b) are formed. In addition, in the embodiment, a large buffering effect t- can be achieved by providing the buffer part (6, a) protruding laterally at the lower part of the packaging case (1) and the buffer part (6b) protruding laterally at the upper part adjacent to each other. I try to get it, but
As shown in FIG. 7, it may be placed in the vertical center of the packaging case il+. It goes without saying that buffer sections (6a) to (6c) may also be provided on the side surface (la) of the case near the outlet of the fluorescent lamp (2). However, in this case, the tongue piece (7) needs to be fixed to the upper surface (lb) of the case by pasting or the like.

The present invention is constructed as described above, and one case has V on the side.
Since the shock absorber is in the shape of a shock absorber, the shock applied to the side of the case is first alleviated by the deformation of this shock absorber, and then the shock is applied to the side of the case. It has the advantage that it is cushioned by materials such as cardboard that is formed, and a large cushioning effect can be obtained without using a special cushioning material. A pair of notches are provided across the bottom surface of the case, and the center of the strip formed between the two notches is bent outward at an acute angle to form a V-shaped buffer. It has the advantage of being simple, simple, and inexpensive.

Claims (1)

[Claims] (1) A pair of notches is provided that spans the entire length of the side surface of the case in the vertical direction and straddles the top or bottom of the case, and the center portion of the strip formed between the two notches is bent outward at an acute angle. A packaging case characterized in that when bent, the bent portion forms a V-shaped buffer portion protruding from the side surface of the case.
