Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging paper box, for example, a packaging paper box suitable for packaging foods such as cup ramen and bagged intramen.

[0002]

2. Description of the Related Art Many foods such as cup noodles, intard noodles in a bag, etc. are transported and stored in a so-called wrap-around packaging paper box.
In a mass retailer, the packaging paper box is often opened in a vertically divided manner, and is displayed and displayed on a display shelf or the like while being stored in a half of the divided paper box.

Conventionally, as a packaging paper box used in such a manner, as shown in FIG. 3, a reinforcing tape (T) for opening is provided inside the side walls (52) (54) and the inner flaps (62) (64). A vertical cut (5) that is attached and cuts the reinforcing tape for opening (T) at the longitudinally intermediate portion of the side walls (52) and (54).
6) and notches (57) continuing on both left and right sides thereof are formed to form opening knobs (61) and (61). From the knobs (61) and (61), a widthwise middle portion of the side wall ( A packaging paper box is known in which the box body is opened and divided into upper and lower parts by tearing and separating 60) into a band shape.

As shown in FIG. 4, side walls (72) (7)
4) And a number of break notches (88) (88) ... are arranged in two rows in parallel on the inner flaps (82) and (84), and the break joints between the break notches (88) and (88) A packaging paper box in which the box main body can be opened and divided by separating the band-shaped separating portions (80) (80) from the box main body by breaking (89) ... is known.

[0005]

However, the packaging paper box using the opening reinforcing tape (T) requires the cost of the opening reinforcing tape (T) itself and the cost of sticking to the box body. However, there is a problem in that the price is slightly higher than the latter so-called zipper type packaging paper box. Also, depending on the quality of the cardboard constituting the packaging paper box, a considerable force may be required to tear the side wall.

In the case of the zipper type, the break notch (88) overlaps the fold as well as near the corner, that is, near the fold between the side walls (72) and (74) and the inner flaps (82) and (84). So that the side walls (72) and (74) and the top wall (71) cannot be bent from the fold between the bottom wall (73) during box production, Cut (88)
... may be bent from the line, and the packaging paper box may not be assembled in a desired form. Furthermore, in addition to such inconveniences at the time of box making, when a large number of packaging paper boxes are stacked, the lower packaging paper box is bent from the row of breaks (88) due to the load from above. Sometimes it does. If the wrapping paper box contains beverages, such as canned beer or canned juice, stored in canned containers, the canned containers themselves receive the load, so the bend from the breaking cut (88) ... May be a so-called blister, but if the food stored in the packaging paper box is food such as instant noodles in a bag or ramen in a cup, the instant noodles or styrene containers may be damaged. is there.

Of course, in order to avoid such a situation, it is only necessary to use a stronger cardboard or to relatively lengthen the length of the breaking connecting portion (89).
In the case of the former, the cost increases, and in the case of the latter, the breakable connecting portions (89)... Become difficult to break, and the opening cannot be performed smoothly.

The present invention has been made in view of the above problems, and has as its object to provide a packaging paper box that can be manufactured without increasing the cost and that can be easily opened by a zipper.

[0009]

In order to achieve the above object, a break notch is provided only on the side wall, and its area is excluded except for the vicinity of the fold between the side wall and the inner flap. Limited to the area. That is, according to the present invention, a plurality of break notches (8) (8)... Are arranged in a pair in the longitudinal direction of the side walls (2) (4) on the pair of opposing side walls (2) (4) of the packaging paper box. (9) that are aligned with each other and between the breaking cuts
(9) In the packaging paper box in which the box body can be opened and divided by separating the strip-shaped separation parts (10) (10) between the rows from the side walls (2) (4) by breaking ... The break notch (8) is provided in an area excluding the vicinity of the folds (32) and (34) between the side walls (2) and (4) and the inner flaps (22) and (24), while the inner flap is provided. (22) At the center of (24), a cut (12) for vertically separating the box body is provided along the length direction of the inner flap, and the cut (12) for vertical separation and the fold (32) are provided. ) And (34), a pair of C-shaped guiding notches (13) and (13) facing the breaking notch (8) of the side wall and converging toward the vertical separating notch (12).
However, a configuration in which the folds (32) and (34) are provided at an interval is adopted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on embodiments shown in the drawings.

The packaging paper box shown in this embodiment is
It follows the basic form of a wrap-around type cardboard packaging paper box as it is, and is made from one piece of cardboard. As shown in an expanded state in FIG. 2, an upper wall (1), a side wall (2), The bottom wall (3), the side wall (4) and the joining piece (5) for sticking the body are connected in series through the folds (41), (42), (43) and (44), and the bottom wall (3) After arranging a predetermined number of bagged instant noodles, which are articles to be packaged, in an upright state on the inner surface, the side wall (2), the upper wall (1), the side wall (4), and the body bonding piece (5) are covered. It is designed to be folded around a package.

The side walls (2) and (4) have, at the center, a longitudinal cut (6) for starting opening, and guide cuts (7), (7) and (7) extending in opposite directions on both left and right sides at both ends thereof. (7) are provided to form the opening knobs (11) and (11), and the connecting portions (9) for breaking from the ends of the guide cuts (7), (7), (7) and (7). Many break notches (8) through ...
Are provided along the length direction toward the end of the side wall and arranged in two rows parallel to each other. (Ten)
Is a separation part between columns.

Further, when the packaging paper box is assembled, the upper wall (1) and the bottom wall (3) come into contact with each other through the folds (31), (31), (33), and (33) from both edges thereof. Outer flaps (21), (21), (23), and (23) are provided to close the openings, and folds (32) are formed from both edges of the side walls (2) and (4).
(32) (34) (34) through the outer flap (21)
(21) (23) Inner flap (2
2) (22) (24) (24) are connected in series.

In each of the inner flaps (22) and (24), a cut (12) for separating the box body vertically is provided in the center along the length direction of the inner flaps (22) and (24). The upper and lower separating cuts (12) and the folds (32), (32), (34)
(34) and a pair of C-shaped cuts (13) (13) (13) facing the break cuts (8) of the side walls (2) and (4) and converging toward the upper and lower separating cuts (12). 13) is provided at an interval from the folds (32), (32), (34), and (34).

From this expanded state, the wrapping paper box is assembled by bending and sticking a required portion of the wrapping paper box. FIG. 1 shows the assembling process. The items to be packaged are stored. The bending and sticking of the required portions are performed in the same manner as in a conventional wrap-around type wrapping paper box, and thus detailed description is omitted.

Thus, the outer flap (21) from the state shown in FIG.
By attaching (23) to the inner flaps (22) and (22), a packaging completed state is obtained. From the completed packaging state, in a mass retailer or the like, to display and display the packaged object together with the packaging paper box on a display shelf or the like, the bottom wall (3) is placed downward and the center of the side walls (2) and (4). Inserting a finger into the opening vertical cut (6), pulling the opening knobs (11) and (11), and pulling it to the left and right, the breakable connecting portions (9) and (9) are sequentially broken to form a strip. The separation part (10) starts to separate from the side wall.
When the band-shaped separation portions (10) and (10) are pulled up to the vicinity of the fold between the inner flap and the breakage cut (8) is not provided in the portion, a slight resistance is received. , The strip-shaped separation part (10) as it is ... inner flap (22)
Keep pulling toward (24), and you will see a C-shaped cut (13)
When (13) is reached, the strip-shaped separating portions (10) and (10) are separated from the box body, whereby the box body can be separated vertically.

In this embodiment, the break notches (8), (8),... Are arranged in parallel with each other, but the arrangement is not limited to this. It may be a wavy shape, a zigzag shape, or the like as disclosed in Japanese Patent Application Laid-Open No. 198247, and the interval between rows may not be constant.

[0018]

As described above, in the packaging paper box according to the present invention, the break notches (8)... Have the folds between the side walls (2) and (4) and the inner flaps (22) and (24). (32) (34) Provided in the area excluding the vicinity, the notch (12) at the center of the inner flaps (22) and (24) for separating the box body up and down is the length of the inner flaps (22) and (24). Along the direction
A pair of a pair of opposing cut-offs (8) on the side wall and converging toward the cut-offs (12) between the upper and lower separation cuts (12) and the folds (32) and (34). C-shaped cut (1
3) Since (13) is provided at an interval from the folds (32) and (34), the break notch (8) during box making
… Prevents unintentional bending from the row of rows, making the box production smooth. Therefore, it is possible to contribute to the improvement of the productivity by eliminating the defective assembly of the packaging paper box in the wrap-around packaging in which the packaging object is packed while assembling the packaging paper box and the adverse effect on the packaging line based on the assembly failure.

Further, since undesired bending is prevented, the length of the connecting portion (9) for breaking is made as short as possible so that the connecting portion (9) of the band-like separating portion (10) can be prevented from the side wall (2) (4). Separation and opening of the packaging box can be facilitated.

Furthermore, since the pressure resistance of the corner portion is higher than that of the conventional packaging paper box provided so that the break notch extends from the side wall to the inner flap, a large number of packaging paper boxes are stepped. Even in the case of stacking, there is no possibility that the box form of the lower packaging box is damaged, and thus the packaged object can be sufficiently protected.
