An arrow display 35 is provided along the circumferential direction.

[Carton sealing operation]
Next, the carton sealing operation will be described.
The contents individually wrapped in advance by the packaging device are arranged by the storage device so as to form a columnar shape as a whole in the storage space 23 of the main body 2.
In addition, an adhesive 28, specifically, hot melt is applied to the outer surface of the cut region 27 of the main body 2 so as not to protrude outward from the cut line.
Thereafter, the side plate portion 22 of the main body 2 is fitted into the inner peripheral side of the side surface portion 32 of the lid 3 to cover the contents. In this state, as shown in FIG. 2, the upper end edge in the axial direction of the side plate portion 22 of the main body 2 faces the lower surface of the top plate 31 of the lid 3 through a predetermined gap X (see FIG. 3). maintain. In this state, the position corresponding to the adhesive 28 is heated from the outer surface side of the side surface portion 32 of the lid body 3, the cut region 27 is adhered to the inner surface of the side surface portion 32 of the lid body 3, and the lid body 3 is attached to the main body 2. Install.
Thereafter, the sealing tape 4 is attached from the outer peripheral surface of the side surface portion 32 of the lid 3 to the bottom surface of the bottom plate 21 of the main body 2, and the sealing process is completed.

[Opening the carton]
Next, the carton opening operation will be described.
First, the user peels off the sealing tape 4.
Thereafter, the user applies a force for relatively moving the main body 2 and the lid 3 in the circumferential direction according to the arrow display 29. Due to the action of this force, the cut region 27 to be bonded to the lid 3 is cut by the cut line 27A from the outer plate 22B of the main body 2, and is in a state of being located in the guide groove 26 as shown in FIG.
In this state, the main body 2 and the lid body 3 are moved in a direction in which the main body 2 and the lid body 3 are relatively separated from each other, whereby the lid body 3 is removed and the contents can be taken out.

When the lid 3 is attached to the main body 2 again for refrigerated storage after taking out a part of the contents, as shown in FIGS. 5 and 6, the cutout region 27 of the lid 3 is the lower edge of the guide groove 26. And the upper edge of the side plate portion 22 of the main body 2 comes into contact with the top plate 31 of the lid 3.
Thereafter, if necessary, the sealing tape 4 is attached again and sealed.
In the sealed state shown in FIGS. 5 and 6, the main body 2 and the lid 3 are close to each other due to the relative positional relationship between the main body 2 and the lid 3 when unopened as shown in FIGS. 2 and 3. Thus, the height dimension is clearly reduced. Further, the main body 2 facing from the opening 33 of the lid 3 is also almost hidden by the lid 3, and it can be seen that it has been opened at a glance. Thus, in the structure of the said embodiment, since it can determine easily that it was opened, unauthorized opening, such as tampering, can be determined easily.

According to the present embodiment as described above, the following effects can be obtained.
(1) In the carton 1 of the present embodiment, the side plate portion 22 of the main body 2 is surrounded by the cut line 27A from the middle portion of one edge in the axial direction of the guide groove portion 26 continuous to the opening surface 24 toward the circumferential direction. A cut area 27 is provided, and the cut area 27 is bonded to the inner surface of the lid 3. And at the time of opening, it is set as the structure by which the cutting area | region 27 is cut off to the cover body 3 side by the cutting line 27A.
For this reason, when the lid 3 is attached to the main body 2, the side plate portion 22 serving as the opening edge of the main body 2 abuts on the top plate 31 of the lid 3, and from the bottom plate 21 of the main body 2 to the top plate 31 of the lid 3. Since the axial distance is shorter than the distance of the unopened carton 1, the user can easily confirm that the carton has been opened. Therefore, even if there is an unauthorized opening such as tampering, it can be easily determined.
And since it is set as the longitudinal cutting area 27 in the circumferential direction, the cutting area 27 cut out on the cover 3 side can be easily formed even in a shallow carton 1 for storing individually wrapped contents such as block cheese. At the same time, the main body 2 and the lid 3 can be easily moved in the circumferential direction to be opened.

(2) In the present embodiment, hot melt as an adhesive 28 is applied in advance to the cutout region 27, and the upper end edge of the side plate portion 22 of the main body 2 is in a predetermined gap with the top plate 31 of the lid 3 in the axial direction. In a state of facing through X (see FIG. 3), heat is applied from the outer peripheral side of the side surface portion 32 of the lid 3 to melt the hot melt, thereby bonding the cut region 27 to the lid 3.
For this reason, the cut-out region 27 of the main body 2 can be easily bonded to the inner surface of the lid 3.

(3) In the present embodiment, as the side plate portion 22 of the main body 2, the inner plate 22 </ b> C is laminated on the inner surface of the cylindrical outer plate 22 </ b> B at least at the position where the cutout 26 </ b> A is closed without being bonded to the cutout region 27. doing.
For this reason, since the axial dimension between the main body 2 and the lid 3 is minimized due to its own weight at the time of resealing, it is difficult to reseal in an unopened state, and unauthorized opening such as tampering is prevented. A configuration that can be easily determined can be easily formed.

(4) In the present embodiment, the sealing tape 4 is attached from the outer peripheral surface of the side surface portion 32 of the lid 3 to the bottom surface of the main body 2.
For this reason, while the tamper-proof effect by the sealing tape 4 is acquired, the structure which becomes difficult for the operation | work which reseals to the relative positional relationship of the main body 2 and the cover body 3 of an unopened state becomes difficult. Obtained with a simple configuration to install.

What is necessary is just to be provided in the position which plugs up the notch 26A at least, such as setting it as the double structure which provides the inner side board 22C over the inner periphery of 22B.

Further, the cutout area 27 is not limited to one place, and may be provided at a plurality of places.
Providing at a plurality of locations is preferable because it becomes more difficult to re-seal the cut region 27 in an unopened state in accordance with the region of the cut line 27A after opening.
The plurality of cutout areas 27 may be provided at equal intervals in the circumferential direction. However, by setting the cutout areas 27 at non-equal intervals, the cutout areas 27 are realigned into the unopened state after opening in accordance with the cutout line 27A area. Since it becomes more difficult to seal, it is preferable.
The cut region 27 is not limited to being formed in a longitudinal shape in the circumferential direction, but is formed in various shapes such as being formed in a longitudinal shape in the axial direction or a semicircular shape from one edge of the guide groove portion 26. can do.

Furthermore, the sealing tape 4 may not be attached.
That is, by providing a plurality of cut regions 27, the main body 2 and the lid 3 are bonded at a plurality of locations. Thus, if sufficient sealing strength with the main body 2 and the cover body 3 is obtained, the sealing tape 4 is not provided, the cost of using the sealing tape 4 can be reduced, and the user's opening workability can also be improved. .
