[Problem to be solved by the present invention]
In the case of Japanese Patent Publication No. 18, since the entire top surface of the carton can be opened, the contents are easy to take out, but the flaps are inserted and fitted, so that when the top surface is opened, the shape of the box cannot be maintained, Since it is decomposed into the original single-wafer state, there is no function of holding the contents, and there is a risk of dispersion. 59-11
No. 073 discloses that the top surface of the carton can be opened in a C shape, but it is inconvenient to take out the contents because the entire surface is not opened. In order to make it easy to take out the entire contents, the operation of dividing horizontally into two parts by a zipper on the side wall and dividing into the body and the lid, and connecting them on the back side to fully open is complicated. Accordingly, an object of the present invention is to obtain a lapland-type carton that can be completely opened along the ridgeline of the top surface of the carton and maintains the shape of the box after opening.

[0004]

SUMMARY OF THE INVENTION The present invention provides the following carton to achieve the above object. That is, a lapland-type carton formed into a box shape by bonding, inserting, and fitting, and can be opened over the entire ridge portion of the surface constituting the top surface of the carton or over most of the ridge lines. As shown in the figure, a cutout such as a zipper or perforation is provided on the ridgeline of the top surface, and the middle flap of the flaps derived from the top plate, bottom plate and side plate is subjected to window cutting or cutting, and adhesive is applied to this portion. Is applied so that three flaps are stuck together, and the carton does not decompose into a single sheet even after the top surface is opened.

[0005]

[Effect] Even if the carton is completely or partially opened along the ridgeline of the top surface of the carton, the middle flap of the three flaps derived from the top plate, the bottom plate, and the side plate is subjected to window cutting or cutting to form this part. Since the adhesive is applied to the three flaps, the three flaps are integrated and do not decompose into the original sheet state, which is suitable for protecting and preserving the contents.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 shows an unfolded state of the carton according to the present invention. Reference numeral 1 denotes a top plate, and a front plate 11 and a rear plate 11 'having front and rear inner flaps 4 and 4' continuously provided through a folding line 10. Are provided continuously, and furthermore, an intermediate flap 5,
5 'are continuously provided, and V-shaped portions are provided at these ridges (folds).
There is a break 2 that leaves a trace in the shape of a letter. Reference numeral 3 denotes the initial opening, and reference numeral 7 denotes a cut formed diagonally from the initial opening 3 to the cuts 2 and 2 of the front and rear ridges. A bottom plate 9 is connected to the back plate 11 '. Outer flaps 6, 6' are connected to the front edge and the rear edge of the bottom plate 9 via a folding line 10, and a trunk flap 12 is connected to the side. The edge is continuously provided via a folding line 10. Then, the back plate 11 'is erected with respect to the bottom plate 9, the top plate 1 is turned back on this, and the front plate 11 is erected, and the inner flaps 4, 4' and the outer flaps are provided with respect to the intermediate flaps 5, 5 '. The box is assembled as shown in FIG. 2 by superposing the flaps 6 and 6 'and attaching the flap 12 to the front plate 11.

The present invention relates to a carton of the wrap round type as described above, in which the intermediate flaps 5 ', 5 are provided with a window 8,
8 'or a cut 13 as shown in FIG. 8. Opening 8, 8 'or cut 13 as described above
7, 9, and 1 in the intermediate flaps 5 and 5 ′ provided with
When the adhesive a is applied like 0, the inner flaps 4 and 4 'and the outer flaps 6 and 6' of the three flaps are bonded with the adhesive a through the windows 8, 8 'and the cut portion 13, and the three flaps are formed. Become one. Therefore, the initial opening 3
Even if the top surface is opened using the cut 2 as shown in FIG. 3 or FIG. 5, the carton will not be disassembled into the original single sheet state as shown in FIG. The opening in FIG. 3 is initially performed from the opening 3 and the opening is advanced through the cut 7, and after reaching the cut 2 provided on the ridge of the intermediate flaps 5 and 5 ', the opening is further continued along the ridge and the back plate 11 is opened. The top plate 1 is removed at the cut line '. The unopened parts 1, 1 'are then removed. 5 is opened using the cut 2 of the entire ridge line,
There is no need to remove the unopened portions 1 'and 1'. In addition, if the perforation 10 'is inserted in the folding line part of the front plate 11, the front plate 11 can be opened and it is convenient.

As described above, a box is formed from a single sheet blank to complete the shape, and a cut is made and opened with a wrap round type carton. A zipper or perforation as shown in the figure or a cut formed by combining them is provided. Open. The cut has the same effect of easiness of bending as the ruled line, and therefore, the ruled line can be substituted with the cut. Depending on the purpose of use, whether the top surface is completely opened or part of the top surface is selected depending on the purpose of use. In order to improve the opening property, a plurality of initial opening ports are provided, but as shown in FIGS. May be taken widely.

As shown in FIG. 6, a normal wrap round type carton or corrugated cardboard has two inner and outer flaps 14, 15, 15 '.
Is glued to complete the box shape. In this case, the flap 1
A slight gap s is generated between the butting surfaces 5 and 15 ', and complete sealing cannot be achieved. In order to completely prevent foreign matter and dust from entering depending on the intermediate food and its inner packaging,
The outer flaps 6 and 6 'are provided so as to close the gap as a three-layer structure. In general, the bonding of a box, a flap, and the like is performed by applying a hot melt adhesive to one of the two sides, and then bending the other side and pressing strongly. In such a method, the three overlapping flaps described above cannot be integrated with an adhesive. That is, three flaps can be overlapped to prevent a gap, but only the bonding of the outer flap and the middle flap can be integrated by the normal bonding as described above, and the inner flap remains folded. In such a state, when the flap is simply inserted and fitted, if the top surface is completely opened, or if it is opened for the most part, the carton will be disassembled into the original sheet blank state, or partially disassembled, and the shape of the box will be Can not be kept, and the box-shaped holding function of the carton is lost, so the configuration of the present invention was adopted.

One of them is to apply a window 8 to the intermediate flaps 5 and 5 'on the side to which the hot melt is applied, in accordance with the application position. A configuration in which a melt is applied is adopted, and the three flaps are integrally bonded. FIG. 1
Intermediate flaps 5, 5 'for applying a hot melt like 0
In this embodiment, a partial cut portion 13 is formed, and hot melt is applied to the inner flaps 4 and 4 'through the cut portion.

From the above, three flaps derived from the side plates including the bottom plate 9 and the top plate 1 and the front plate 11 and the back plate 11 ', that is, the intermediate flaps 5, 5' and the outer flaps 6, 6 '. , The inner flaps 4 and 4 ′ are bonded and integrated, so that the top panel 1, the front panel 11 and the rear panel 1
Even if the ridgeline between 1 ′ and the ridgeline between the top plate 1 and the intermediate flaps 5 and 5 ′ are cut and the top surface is completely opened, all the flaps are integrally bonded to the bottom plate 9, The carton can be kept in the shape of the box without being broken down into the original sheet. Therefore, the carton, whose top surface can be completely opened, is easy to remove and has excellent workability. The box-shaped holding function is suitable for protecting and preserving partially remaining contents. The zippers and perforations provided on the ridges on the top surface are for the purpose of facilitating opening. However, when the zippers are opened, remarkable V-shaped cut marks remain as shown in FIGS. FIG.
By combining the zipper 2 and the perforations 2 ', which leave a V-shaped cut mark as shown in the above, a V-shaped cut mark can be left on the ridge at an arbitrary pitch. Further, there is an advantage that the content can be easily determined by comparing the V-shaped cut traces remaining at predetermined positions on the vertical and horizontal ridge lines. In any case, a zipper or a perforation having a strength suitable for the moldability of the carton, the impact resistance during transportation, and the opening property during use, and a cut formed by combining them are provided.

[0012]

According to the present invention, in the wrap round type carton, the three flaps derived from the bottom surface, the top surface, and the side plate are bonded and integrated, so that the ridge between the top surface and the flaps. Even if the carton is cut and the top surface is fully opened, the carton does not disassemble into the original, single-sheet state, and the shape of the box can be maintained. Therefore, the contents can be easily taken out, the workability is excellent, and the box-shaped holding function is suitable for protecting and preserving the partially left contents.
