2. Description of the Related Art Electronic equipment parts such as floppy disks and CD cassettes, sealed books whose contents are not known from the outside, and paper or resin film used for sealing and storing products such as picture postcards and letter sets. As shown in FIG. 10 (front view of conventional product) and FIG. 11 (enlarged vertical cross-sectional side view of FIG. 10) of the attached drawings, the conventional sealed-type packaging box related to the template material is connected to the periphery of the front surface 1 of the developed template. The back surface 7 of the unfolding paper pattern, which is folded into each of the surrounding surfaces and the lid surface 6 is attached and sealed to assemble into a sealed type packaging box, has the same length as the front surface 1 and is attached to the glue flaps 3 and 3 '. Then, the lid surface 6 having a length reaching the attached back surface 7 is superposed on the back surface 7 from above by closing the opening of the entrance and exit, and the flaps 3, 3 '
And a back surface 7 and a lid surface 6 are laminated and sealed in a triple layer.

[0003]

The conventional packaging box of this kind has a narrow opening and an inconvenient entrance / exit for the storage because of the sticking and sealing of the front surface 1 and the rear surface 7 having the same size and the same length. The superposition of the surface 6 on the back surface 7 is performed by covering the lid surface 6 with a triple layer.
Is a step lid with respect to the back surface 7, and the sealing appearance is bad, and the step edge of the lid surface 6 is a catching edge, which is very inconvenient, and it is inconvenient for aligning, stacking, and organizing and storing (FIG. 11). reference). Furthermore, the lid surface 6 after the bag is once opened and the stored items are taken in and out.
Since the closing lid is also a stepped lid as described above due to the stacking lid, it is easy to open the lid even if it is slightly caught, and the stepped lid is very disturbing and inconvenient for organizing and storing. Since the development paper pattern of three-layer sticking formation requires a large area, the paper pattern cost is high, the product cost is correspondingly high, and it is uneconomical, and the demand is low. It has many drawbacks.

In view of the above-mentioned drawbacks of the conventional products, the present invention provides: A, the lid surface is in the form of a sticking seal which has a flat surface with no step with respect to the back surface, and even when the lid is opened after opening, On the other hand, by making it a flat surface with no steps, it is possible to easily eliminate the drawbacks of the conventional step closing lid. B, the flat surface sealing method with two steps attached to the lid surface makes it possible to make the sealing appearance extremely good, and to make it possible to arrange and store the sealing portion without disturbing the sealing portion. C. Furthermore, even if the lid is opened once, it can be conveniently stored under the stepless lid. D, With the back sticking shorter than the front, the opening of the entrance and exit can be made very wide by opening the lid to facilitate the handling of putting in and out of stored items. E. With the short back surface formation and the concavo-convex fitting formation between the back surface and the lid surface, the development paper pattern of this kind of packaging box is made into the minimum area paper pattern, the paper pattern cost is reduced while saving the paper surface, economical and demand We will ensure the low-volume production of highly reliable products. F, By forming the concave and convex fitting on the back surface and the lid surface, the fit of the tongue flap with respect to the horizontal cut and the deviation closing lid are eliminated, and a stable and reliable closing product is provided. G, Affix the seal on the lid so that it can be peeled off easily and neatly. The purpose is to

[0005]

[Means for Solving the Problems] Adhesive flaps symmetrical to both sides and both sides on the front side, a lid side surface and a lid surface on the upper side, and a bottom side surface and a back side on the lower side, each of which is bent and the lid surface is attached and sealed. Then, the rear surface of the unfolding paper pattern to be assembled into the closed-type packaging box is formed into a recess which is shorter than the front surface and has an opening surface with a horizontal cut at a required depth, and the short rear surface is used for the glue flap. A means for sticking the upper part of the flap in an exposed state, and a lid surface formed with a tongue flap that has a symmetrical convex portion that fits in a recess on the back surface and that fits in a horizontal cut,
With the lid surface and the exposed upper portion of the flap, the convex portion is fitted into the recess on the back surface in a concavo-convex manner, and only the tongue flap is placed on the upper surface of the horizontal cut portion. It is a means for sticking and sealing in a planar shape, and a means for fitting the tongue flap to the horizontally cut back surface of the lid surface after opening to make a sticking back surface and a stepless flat surface lid, and also a short back surface The surface of each exposed upper part of the bilateral symmetric glue margin flap is exposed as a non-glued surface, the contour is half-cut on that surface, and only the contour range surface is the glue coated surface on the lid surface. And means.

[0006]

[Operation] When the back side, which is shorter than the front side, is attached to the glue flap, the upper part of the flap is exposed on the attaching surface with respect to the lid surface, and the upper part of the bilaterally symmetrical exposure is open, and the entrance is wide open. , The exposed sticking surface is sealed by covering the opening with the lid surface that fits in the recess and recess on the short back, and the tongue flap is placed on the horizontal cut part. Just a short back and a flat flat surface with no steps are attached, and once the lid is opened, the flap is attached to the horizontal cut on the back and the lid is closed. And it becomes a flat surface lid with no step.

Further, when the lid surface is pasted on the partially glued surface in the half cut of the contour to be applied to the exposed upper portion of the glue allowance flap, the lid surface unsealing using the flap of the tongue flap as a picking piece is easy to peel off and peeling residue is not attached. There are few beautiful peels.
