Description

[Detailed description of the invention] This invention relates to a packaging box for a straight tube type fluorescent lamp apparatus.

Conventionally, this type of packaging box has been disclosed in Japanese Utility Model Application Publication No. 50-10626.

This packaging box requires a separate end-closing member to be fixed to the housing with stitches, so the material cost is high and assembly is troublesome. Because there was no buffer plate interposed between the end plate of the interior reflector of the straight tube fluorescent lamp, the buffering effect was insufficient, and the rigidity and compressive strength of both ends of the casing were also insufficient. The problem was that there was no.

This invention has a casing in which an end plate is integrated with a bottom plate and a side plate, and a winding press plate is attached to the end plate of this casing via a connecting plate to follow the inner surface of the end plate of the interior reflector. By interposing a plurality of inverted U-shaped inner and outer buffer plates connected to each other and connected to both ends of the side plate between the outer surface of the end plate of the reflector and the end plate of the casing, the above-mentioned effect can be achieved. A straight tube fluorescent lamp that solves the conventional problems and has low material costs, easy assembly or packaging, sufficient cushioning, and high rigidity and compressive strength at both ends of the casing. The aim is to provide packaging boxes for instruments.

An embodiment of this invention will be described below with reference to the drawings.

That is, in FIG. 1, A is a long and narrow packaging case made of cardboard or the like, 1 is a bottom plate of this case, 2 is both side plates thereof, and 3 is formed in series with this side plate, and the tip is in the packaging state. The lid plates to be matched, 4 are end plates provided at both ends of the bottom plate 1, and 5 is a trapezoidal reflector provided at the tip via a connecting plate 6, which has the same shape as the end plate of the interior reflector plate described later. A rewind presser plate 7 for fixing the plate is a tongue piece for protecting the reflective surface of the interior reflector plate connected to the tip of the presser plate 5. By bending it along the bending line 8, each end piece can be used to protect the interior reflector. It is designed to come into contact with the reflective surface of the plate.

In addition, 10.11 is a buffer in which the bottom plate 1 side part is connected to both ends of the side plates 2, 2, and the opposite bottom plate 1 side part is separated from the side plates 2, 2. They are arranged on both sides of the end plate 4, the connecting plate 6, and the holding plate 5, separated from these.

Note that the broken line 9 in FIG. 12. 13. 14.
15. 17 each indicate a bending line.

When forming the casing from the punched state shown in FIG. 1, as shown in FIG. Fold these buffer plates 10 and 11 into an inverted U-shape along both bending lines 12° and 13, respectively.
．． 15 to position it inside the end plate 4.

At this time, the relationship between the edge buffer plates 10 and 11 is such that the buffer plate 10 having the bending line 14 on the inside is inserted and clamped into the buffer plate 11 having the bending line 15 on the outside as shown in FIG. This strengthens the shape retention and cushioning effect of the part.

Next, the interior reflecting plate 16 shown in FIG. 2 is placed on the bottom plate 1 with both reflecting surfaces 16a facing downward.

After this placement, each end plate 4 is raised vertically,
With the connecting plate 6 inside, bend this part using the bend line 17 so that it is parallel to the bottom plate 1, and then bend the presser plate 5 at the tip at a right angle toward the bottom plate 1. As a result, each buffer plate 10.11 and the end plate 16b of the reflection plate 16 in the overlapping state are held so as to be held inside thereof.

Then, from this holding state, bend the protective tongue piece 7 along the bending line 8 and attach each end piece to each reflective surface 16a of the reflective plate 16.
bring it into contact with.

That is, in this state, the reflector 16 is fixed inside the packaging casing A, and then the instrument main body 17 is assembled thereon, so that the presser plate 5 and the protective tongue piece 7 are connected to the reflector 16 and the instrument main body 1.
It also serves as a spacer between 7.

Finally, the lid plates 3 are closed together and sealed with tape or the like to complete the packaging work.

As explained above, in the packaging box of this invention, a part of the buffer plate is attached to both ends of the side plate of the case in which both side plates and both end plates are attached to the bottom plate. The entire packaging box, including the packaging box, can be constructed from a single sheet of paperboard such as corrugated cardboard, resulting in low material costs, and since there are no separate members, work efficiency during assembly, ie, packaging work, is also good.

In addition, according to this invention, both edge buffer plates, which are partially attached to both side panels of the housing, are bent into an inverted U shape, and one buffer plate is sandwiched inward by the other buffer plate. Bending the buffer plate from the side plate and positioning it between the bottom plate and the connecting plate,
Since the end plate of the internal reflector of the straight tube type fluorescent lamp is interposed between the end plate of the casing and the holding plate, there are a total of four layers with both buffers, and the rigidity of both ends of the casing is reduced. Growing up,
Because this type of packaging box is long, it can prevent deformation due to twisting loads that tend to occur, and has a good cushioning function.Furthermore, the end of the case has high compressive strength, so it will not deform even if it collides with other objects. Since the reflector plate is positioned between the holding plate and the buffer plate, it is possible to securely position, support and fix the reflector plate, and there is no possibility of parts such as the reflector plate rattling. can get.
