Means for Solving the Problems A first invention of the present invention is:
A glued panel, a front panel, a first side panel, a back panel, and a second side panel are respectively connected via bending lines, and substantially above an edge of the second side panel to which the back panel is not connected. On the half, a top open panel is continuously provided via a cut line, and a substantially U-shaped opening is defined by the cut line at the upper edge of the front panel, and is locked at a substantially center near the opening. A groove is provided, a sealing panel is continuously provided on the lower edge via a folding line, and a sealing panel is continuously provided via a bending line on both side edges of the back panel, and a top open panel is provided. A front panel and a first side panel of a blank provided with a sealing panel connected to the upper edge via a bending line and provided with an insertion flap inserted into the locking groove substantially at the center of the lower edge. Bend, second side The back side of the panel and the surface of the glued panel are bonded with an adhesive, the back side of the top open panel and the surface of the opening portion of the front panel are bonded with an adhesive, and the lower side of each of the front panel and the back panel A paper box in which each sealing panel provided on the edge is bent and sealed, and each sealing panel provided on the upper edge of the back panel and the top open panel is bent and sealed, and the top open panel is inserted outward from the flap. When peeled off, the top open panel separates from the second side panel, and the opening of the front panel adhered to the top open panel is cut off from the cut line to separate and open from the front panel. When the panel is closed, the insertion flap is locked by a locking groove provided in the front panel and closed. The top is an open paper box.

According to a second aspect of the present invention, there is provided the top open paper box according to the first aspect, wherein the top open paper box can be opened and then resealed.

[0008]

According to the present invention as described above, a glued panel,
A front panel, a first side panel, a back panel, and a second side panel are respectively connected via a bending line, and a substantially upper half of an edge of the second side panel on which the back panel is not connected is provided. The top open panel is continuously connected via the cut line, and the front panel has a blank structure in which a substantially U-shaped opening is defined by the cut line at the upper edge. Can be manufactured at the same time in the step of folding and sucking each panel. Further, since the paper box after the production of the trunk has the same sealing structure as the seal end carton, it can be filled by a normally used filling machine.

Further, a locking groove is provided substantially at the center near the opening portion, and an insertion flap inserted into the locking groove is provided substantially at the center of the lower edge of the top open panel. Later, resealing with the top open panel is possible.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments. <Embodiment 1> FIG. 1 is a development view of an embodiment of a resealable paper box according to the present invention.

As shown in FIG. 1, the resealable top-open paper box of the present invention has a glue panel 11, a front panel 12, a first side panel 13, a back panel 14, and a second side panel 15, each of which has a folding line. It is installed continuously through.

A substantially upper half of the edge of the second side panel 15 on which the rear panel 14 is not connected is provided with a cut line a.
, A top open panel 16 is continuously provided.

A substantially U-shaped opening portion 121 is defined by a cut line b at the upper edge of the front panel 12, and a locking groove for locking an insertion flap 162 described later is provided substantially at the center near the opening portion. c is drilled, and a sealing panel 122 is connected to the lower edge via a bending line.

An upper flap 131 is connected to the upper edge of the first side panel 13 and a lower flap 132 is connected to the lower edge thereof via a bending line.

The upper and lower edges of the rear panel 14 are respectively provided with sealing panels 141, 1 and 1 through bending lines.
42 are provided in series.

An upper flap 151 is connected to the upper edge of the second side panel 15 and a lower flap 152 is connected to the lower edge thereof via a bending line.

A sealing panel 161 is connected to the upper edge of the top open panel 16 via a bending line.
At the approximate center of the lower edge, an insertion flap 162 to be inserted into the locking groove c is formed.

As the break lines a and b, perforations, semi-interrupted broken lines, tear lines with joints, etc. can be used, but tear lines with joints are preferable because they can tear the paper relatively easily. .

The assembling and filling of the contents such as confectionery are performed as follows. That is, first, the glued panel 11
For example, while partially applying a hot melt adhesive or the like to each surface of the opening portion 121 of the front panel,
2 and then the second side panel 15 is folded thereon, and the surface of the glue panel 11 and the second side panel 15
And the front surface of the opening portion 121 and the back surface of the top open panel 16 are adhered to each other, folded in a sleeve shape, and the first operation of attaching the top open panel to the front panel is completed. This operation can be easily performed using a generally known sack sticking machine. Since the sleeve can be stored or transported in the folded state, it is advantageous because it takes up little space.

Next, the folded sleeve is raised and the lower flaps 132 and 152 are applied while applying a known adhesive such as a hot melt adhesive to the back surface of the sealing panel 142, for example.
Then, the sealing panels 122 and 142 are bent along the folding line, and the sealing panels 142 and 122 are adhered to each other to form a bottom and are sealed.

Next, contents such as confectionery are filled from the opening opposite to the side where the bottom is formed, and the upper flaps 131 and 151 and the sealing panels 141 and 16 are filled in the same manner as described above.
1 is folded along the folding line, and the sealing panels 141 and 161 are adhered to each other with an adhesive, and the second operation of filling the contents and box-making is completed.

A series of operations of the filling and the box making can be automatically performed by a generally known cartoning machine.

The removal and resealing of the contents such as confectionery are performed as follows. In other words, when the insertion flap 162 formed on the top open panel 16 is lifted outward by holding it, the top open panel 16
Is separated from the second side panel 15 by tearing from the cut line a, and the opening portion 121 of the front panel bonded to the top open panel is torn along the cut line b,
The front panel 12 is opened so that the contents can be taken out (see FIG. 2).

Return the top open panel 16 to the inside,
When the insertion flap 162 is inserted into the locking groove c formed in the front panel 12, the top open panel 16
Is inserted into the front panel 12 and resealing is completed (see FIG. 3). Further, in addition to providing the locking groove at the time of resealing, it can be inserted into the upper end of the front panel after the opening is cut off. In this case, the dimensions of the top open panel are also adjusted.

[0025]

As described above, the resealable top-open paper box of the present invention can be box-formed and filled only by using a generally known sack sticking machine and a cartoning machine. This eliminates the need for re-sticking to the body of the box, contributing to labor savings and cost reduction.
