Description

[Detailed Description of the Invention] The present invention relates to a paper box for storing a straight tube fluorescent lamp.

Generally, the above-mentioned paper box is assembled by folding a sheet of paper into a rectangular shape to form four elongated rectangular side plates. The side plates at both ends are integrally connected by inserting the flap into a notch in the side plate at the other end. Then, so that the thick insertion tongue piece can be easily inserted into the cut,
Conventionally, Japanese Utility Model Publication No. 14-13391 discloses a method of forming an insertion hole along the insertion portion of the cut.

However, the above-mentioned holes in the mount do not require a separate punching process to remove the mount in the holes after the mount is formed using a press machine; if the holes are relatively large, the punching process can also be performed by a machine. However, the holes small enough to insert the insertion tongues as described above can only be made by hand, and there is a problem in that the efficiency of molding the mount is significantly reduced.

However, in the present invention, a top plate and a bottom plate are connected to each other through folds on both sides in the longitudinal direction of a first side plate having an elongated rectangular shape, and a flap is connected to the top plate through a fold, and Second side plates are connected to the bottom plate through folds, and a plurality of engagement tongues each having a dogleg-shaped bulge on both sides are connected to the long side edges of the second side plates. In a straight tube fluorescent lamp storage paper box in which a plurality of inverted gate-shaped cuts into which tongue pieces are inserted are formed in the flap, the first one on both sides of the lower edge of the cut
The cuts are made along the folds, and a second cut connecting these first cuts is recessed toward the flap by approximately the thickness of the paper relative to the first cut.

Therefore, according to the present invention, when the flap is bent at a substantially right angle with respect to the top plate, the part of the flap closer to the top plate than the second cut protrudes on the same plane as the top plate. Since a hole for inserting the insertion tongue piece is formed between each cut, there is no need to form a preliminary hole in the mount, and the mount can be efficiently formed in one step.
The insertion tongue piece can be easily inserted into the cut.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a paper box mount made of paperboard. In the figure, 1 is an elongated rectangular first side plate, and a top plate 2 is attached to both longitudinal sides of the first side plate 1 through folds a and b.
and the bottom plate 3 are arranged in series.

Further, an elongated trapezoidal flap 4 is connected to the top plate 2 via a fold d, while a second elongated rectangular side plate 5 is connected to the bottom plate 3 via a fold c.

A plurality of folds k are formed on the outer end of the second side plate 5.
While the engaging tongues 9 are connected to each other through the flaps 4, undulating tongues 10 are formed at positions corresponding to the engaging tongues 9 of the flap 4.

The specific structure of this undulating tongue piece 10 will be described in detail based on FIG. 2. First, first cuts 11, 11 at both ends along the fold d are formed, and
A convex second cut 12 is formed which is located closer to the flap 4 by approximately the paper thickness than the first cut 1 and which connects the first cuts 11 and 11, and further includes both the first cuts 1.
A reverse gate-shaped cut
By providing this, an undulating tongue piece 10 that can be raised and lowered with respect to the flap 4 is constructed.

Next, the specific structure of the engaging tongue piece 9 will be explained in detail based on FIG. 3.

This engaging tongue piece 9 has a linear first side 14 and two second sides 15, 15 connected from both ends of the first side 14 in a “dog” shape or a reverse “dog” shape. The middle part has a bulging shape, and the length of the first side 14 is
L ₁ is the first point in the undulating tongue 10 shown in FIG.
The length is set to be approximately equal to or longer than the distance ₁ between the inner ends of the cuts 11, 11.

Further, the distance L ₂ between the vertices 15a, 15a on the second sides 15, 15 of the “dog” shape and inverted “dog” shape is less than the distance ₂ between the outer ends of the first cuts 11, 11. is also set large.

That is, the dimensions of each element are set so that the relational expressions L ₁ ≦ ₁ and L ₂ > ₂ are satisfied.

The illustrated embodiment is configured as described above,
The action will be explained below.

Now, after temporarily folding the top plate 2, bottom plate 3, and flap 4 along each fold line a, b, and d, place a straight tube fluorescent lamp (not shown) on the mount and fold each fold line again. a,
When folded along the lines b and d, the mount is assembled and becomes as shown in Fig. 4. In other words, top plate 2 and bottom plate 3
As shown in the figure, an opening Z is formed between the openings Z, and a portion 2a of the cut
A hole is formed between the cuts 11, 11.

The opening Z is closed by overlapping the second side plate 5 on the flap 4, and its operation will be explained below based on FIGS. 4 to 7.

Now, after bending the second side plate 5 along the fold c and the insertion tongue piece 9 along the fold k, insert the insertion tongue piece 9 through the hole into the cut x. Then, the undulating tongue piece 10 is tilted inward to the first
Since the tongue insertion space becomes larger due to the third cuts 11, 12, and 13 (see Fig. 2), the insertion tongue 9 with the relationship L ₂ > ₂ also fills this large tongue insertion space. It is inserted inward through the cut X.
(See FIG. 5) After the insertion tongue 9 is inserted, the undulating tongue 10 returns to its original position due to the elasticity of the paperboard itself, so that the upper end 10a of the undulating tongue 10
(See Fig. 6) to press the engaging tongue piece 9 against the top plate 2,
Moreover, the apexes 15a, 15a of the second sides 15, 15 of the "dog" shape or inverted "dog" shape of the engaging tongue piece 9 are the flaps at the ends of the first cuts 11, 11, as shown in FIG. 4, the engaging tongue piece 9 closes the opening Z in a locked state.

As is clear from the above embodiments, the present invention has a top plate 2 and a bottom plate 3 connected to each other on both sides in the longitudinal direction of a first side plate 1 having an elongated rectangular shape through folds a and b. A flap 4 is connected to the plate 2 through the fold d, and a second side plate 5 is connected to the bottom plate 3 through the fold c, and an engaging tongue piece is formed to bulge out in a dogleg shape on both sides. 9 are arranged in a row on the long side edge of the second side plate 5, and a plurality of inverted gate-shaped cuts x into which the insertion tongue pieces 9 are inserted are formed in the flap 4. The first cuts 11, 11 on both sides of the lower edge of the cut x are aligned with the fold d, and the second cut 12 connecting these first cuts 11, 11 is made by approximately the paper thickness than the first cuts 11, 11. It is recessed toward the flap 4 side, and when the flap 4 is bent at a substantially right angle to the top plate 2,
By protruding the portion of the cut x closer to the top plate 2 than the second cut 12 on the same plane as the top plate 2, a hole for inserting the insertion tongue piece 9 is formed between the first cuts 11 and 11. Therefore, there is no need to form a preliminary hole in the mount, the mount can be efficiently formed in one step, and the insertion tongue piece 9 can be easily inserted into the cut x, which is a remarkable effect. .
