Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a packaging box for packaging relatively small electrical products and the like.

Conventional technology Conventionally, this type of packaging box is generally sealed by folding down a pair of inner flaps, then folding down a pair of outer flaps, and then pasting adhesive tape along the butting edges of the outer flaps. It was spot on.

Problems to be Solved by the Invention In such a conventional configuration, there was a problem that once the adhesive tape was removed, the packaging device could not be used again as a new packaging device.

This invention solves these problems,
To provide a packaging box that can be easily and inexpensively resealed in the same way as a new packaging box.

Means for Solving the Problems In order to solve the above problems, the present invention provides a packaging box having a pair of inner flaps that open and close and a pair of outer flaps that open and close. The inner flap is formed into a substantially convex shape by providing two score lines perpendicular to and parallel to each other, and also providing a score line parallel to the tip side and having an uncut portion in the center. The pair of outer flaps is provided with a folding line parallel to the tip side of the outer flap, and notched recesses at both ends of the tip side of the outer flap, and the cutout is perpendicular to the tip side of the substantially convex inner flap. A notched recess for inserting a side along the insertion line is formed in the vicinity of the tip in correspondence with the side of the substantially convex inner flap.

Function: With this configuration, the pair of outer flaps is bent inward from the folding line, and both sides of the pair of substantially convex inner flaps are inserted into the notched recesses near the tips of the flaps. The inner flap and the outer flap are sealed by inserting the cutout recess of the outer flap to the end of the cut line of the inner flap while sliding it over the upper surface of the cut line with the inner flap left uncut. I can do it.

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

In the figure, 1 is a pair of inner flaps 2 that open and close.
This is an A-1 type cardboard packaging box that has a pair of outer flaps 3 that can be opened and closed, and has two cut lines 2a and 2b that are perpendicular to the abutting sides of the pair of inner flaps 2 and parallel to each other. , a score line 2c that is parallel to the abutting sides and has an uncut portion in the center, and a score line 2c that has the two mutually parallel score lines 2a, 2b and the uncut portion. A substantially convex inner flap is formed by making a tapered cut line 2d in the end face perpendicular to the inner flap. A pair of outer flaps 3 is provided with a folding line 4 parallel to the abutting sides of the outer flaps 3, and cutout recesses 3a are provided at both ends of the abutting sides of the outer flaps 3. Further, the substantially convex inner flap 2
In order to pass through the side portions along the score lines 2a, 2b, and 2d of the outer flap 3, the score lines 2a, 2 of the substantially convex inner flap 2 are formed near the tip of the outer flap 3.
A cut recess 3d is provided corresponding to the shape of the side portion along lines b and 2d. Note that the width dimension A of the notch recess 3a is the width dimension B between the score line 2c of the inner flap 2 having the uncut portion and the folding line of the inner flap 2.
(A≧B). Further, the height h of the outer flap 3 including the folding line 4 is less than half the total height H of the flap 3 (h<H/2).

Furthermore, the length dimension C of the cut line 2c parallel to the abutting side of the inner flap 2 is the height dimension D between the continuous folding line of the outer flap 3 and the side surface of the packaging box 1 and the notch recess 3a.
(C≧D). Next, the notch recess 3b of the outer flap 3 is formed in a direction parallel to the folding line 4.
It is constructed by long and short score lines 3c and 3d of a book, and is made to correspond to the shape and dimensions of the side portions of the substantially convex inner flap 2 along the score lines 2a, 2b and 2d.

In the above configuration, the pair of outer flaps 3 are bent inward from the folding line 4, and the cut lines 2a, 2b, and 2d of the pair of substantially convex inner flaps 2 are aligned with the cut recesses 3b of the outer flaps 3. Insert the edges along the line. At this time, the outer flap 3 has inner flaps 2 on both sides.
Since it is provided so that it can be easily slid over the width B portion of the inner flap 2 toward the center, it is possible to insert the inner flap 2 up to the end of the uncut cut line 2c at the center of the inner flap 2. The portion between the abutting side of the outer flap 3 and the cut recess 3b of the outer flap 3 can be brought into good contact with the substantially convex inner flap surface at the end of the cut line 2c. Sealing is also possible.

Effects of the invention As described above, according to the invention, the inner flap is formed into a substantially convex shape, and the outer flap is formed with folding lines, notched recesses, and notched recesses, thereby achieving good sealing of the inner and outer flaps. It is easy and inexpensive to make, and can be opened and closed repeatedly, allowing for reuse.
