Front plate 1, bottom plate 2, rear plate 3, lid plate 4, side plate 8, cover lid piece 5 extending from cover plate 4 in a direction to cover front plate 1, and cover lid piece 5
A rectangular wrapping film storage box whose main part is the unsealing piece 6 arranged via the cutoff line 10 is described in, for example, Japanese Utility Model Laid-Open No. 59-28022.
Most of this type of box body is made of paperboard, and the part board surface is formed by bending and bending at a substantially right angle at each folding line portion and appropriately pasting. Then, the box body is opened by peeling off the bonded portion between the local joints 9 scattered on the surface of the front plate 1 and the back surface of the unsealing piece 6 and by cutting the unsealing piece 6 from the cut line 10. It is also widely known that a necessary amount of the wrap film F is pulled out from the winding film R stored inside and cut by a cutting tool K provided in the box body. This type of storage box is roughly classified into one having a side cover lid piece 11 extending from the cover plate 4 in a direction to cover the side plate 8 and one having no side cover lid 11. The cutting tool K is attached to the bottom plate 2 at a mounting position. In many cases, it is the plate surface near the ridge with the front plate 1, the upper end of the front plate 1 and the tip of the cover lid piece. As the overall shape of the cutting tool (the shape of the virtual line connecting the cutting edges), a straight shape, a concave arc shape, a convex arc shape, a V-shaped projection shape, a trapezoidal projection shape, and the like are known. The types of blades are metal, plastic,
It is known that paper, vulcanized hardened paper and the like, the edges of which are processed into a saw-tooth shape, the ones coated with abrasive grains, and the combination of both processes are used. As a method of deploying this cutting tool, a method of fixing the band processed into the cutting tool to a suitable place of the mount with a caulking tool or an adhesive, a part of the mount is directly processed into the cutting tool, and a practical box body is used. It is known to use a cutting tool that is exposed at the end of the process.

体の外観品位を著るしく低下させる問題点がある。In response to market (consumer) demands placed on this type of storage box, the strength of bonding the opening piece 6 to the front plate 1 is increased, and at the distribution stage up to the consumer. Make sure that the unsealing piece does not peel off / separate, and that the unsealing piece 6 is easy to remove and does not cause an unsightly peeling state (a state in which the appearance quality of the box is maintained) at the stage of practical use by consumers. There is a request to ask. In response to this requirement, at present, the actual bonding area per scattered local joint is approximately 38.5 mm 2 or more (diameter is approximately 7
(Large than the circle of mm) keeps the bonding area, and the peeling of individual local joints is a half cut line (almost half the thickness of the paperboard) placed in the outer peripheral area of the actual bonding area. By promoting the surface layer peeling of the front paper board in the area surrounded by the area, the above requirements have been addressed by adjusting the bonding strength and limiting the layer peeling range. There is a strong tendency to require a high degree of decorativeness in the surface design, and in a storage box that incorporates this decorativeness, even if it is assumed that peeling at the local joint progressed cleanly as designed, Several clear peel marks with an area, that is, a size of about 78.5 mm 2 or more (larger than a circle with a diameter of about 10 mm in terms of circle), are scattered on the decorative printed surface of the box. However, there is a problem that the appearance quality of the box is significantly deteriorated.

のになっている。First, in order to clarify the difference between the main requirements, the structure of the conventional local joint portion 19 shown in FIG. 4C will be described in advance. Also in the case of the conventional local joint portion 19, conceptually, it is scattered on the surface of the front plate 1 on which the entire surface varnish coating process is performed, and the adhesive is applied, but the varnish is not applied. The local joint 19 has a larger area (about 78.5 mm 2 or more) than the local joint so as to completely surround the inside of the area surrounded by the half-cut line 16 (the local joint 19 Is located between the outer circumference and the half cut line 16). In addition, the area per local joint 19 is as large as about 38.5 mm 2 or more.

たものである。This structure is set to fulfill the following roles. That is, the front plate 1 in which the local joints 19 are scattered
Even when the adhesive is applied to the surface of the strip in the longitudinal direction and pasted on the back surface of the unsealing piece 6, the adhesive effect in the varnish coating processed portion only serves as a temporary fixing, and the strong bonding is not achieved. This is an area portion of the local joint portion 19. However, when peeling it off, one of the paperboards with weaker surface strength causes surface layer peeling, and the peeled paper piece adheres to the stronger paperboard via the adhesive layer. To be Therefore,
When the adhesive strength is constant, the bonding strength is proportional to the delamination strength of the weaker surface of the target paperboard, but the variation becomes large if the width and depth of the delaminated surface are not adjusted. Generally, the surface strength of this kind of paperboard as it is is stronger on the front surface side than on the back surface side. Therefore, in conventional local joints,
It is intended to reduce the surface strength by inserting a half-cut line 16 on the front plate side that should have a strong surface strength, and to easily and reliably cause the surface layer peeling on the front plate surface side of the area range delimited by the half-cut line 16. It was done. That is, by adjusting the bonding strength of the local joints within the area delimited by the half-cut line 16 and by controlling the place and the area where the surface layer is peeled off, the peeling is facilitated and the appearance quality of the box body after peeling is maintained. The technical idea is to achieve harmony.

る効果がある。On the other hand, the area of the local joint portion 9 of the present invention is about 19.6 mm 2 or less per piece, which is smaller than almost half of the conventional product, and the half cut line 16 does not exist. That is, only 3 to 10 local joints 9 are scattered in the longitudinal direction on the front plate surface that has been subjected to the varnish coating process. This action is the same as the conventional product when it is pasted with an adhesive, but at the time of peeling, the minimal surface area (the area equivalent to the area of the local joint) on the back side of the unsealing piece with weak paperboard surface peels off the surface layer. And is attached to the surface side of the local joint on the front plate. This phenomenon is a phenomenon that occurs when the area of the local joint is made small on the front side of the paperboard where the difference in the strength of the paperboard between the front and back is large (front> back). It is a phenomenon. Therefore, also in the case of the present invention, the surface of the locally joined portion becomes whitish due to the layer peeling piece on the back side of the unsealed piece, but the brown paperboard substrate is about three times as large as the half cut line (area about 78.5 mm). Compared to the conventional product that is exposed at the size of 2 ), it can be said that it is almost inconspicuous. Moreover, in this product, if the printing design of the front plate surface portion in which the local joint is arranged is, for example, white or a color pattern with a lot of white areas, the effect that the existence cannot be understood unless it is watched is there.

悪化させる。Various shapes can be adopted as the shape of the local joint, for example, triangular, quadrangular, star-shaped, heart-shaped, clover-shaped, as well as conventional shapes such as circular, elliptical and oval. It may be diamond type, spade type, etc. In short, the area per piece is about 19.6 mm 2 (circle with diameter of about 5 mm in yen) to about 0.8 mm 2 (circle with diameter of about 1 mm in yen). It is sufficient if the area of is industrially available. As this area is smaller, peeling traces are less visible and peeling is easier, but the holding property of the sealing tends to decrease. This harmony is performed by arranging the number of local joints and the areas having different areas scattered according to the length of the box.
It is better to use one with an area of about 9.6 mm 2 (circle with a diameter of about 3.5 mm when converted to a circle) to about 1.8 mm 2 (circle with a diameter of 1.5 mm when converted to a circle) The number of arrays is preferably limited to 4 to 8 because it is easy to achieve harmony.
The center-to-center distance is preferably about 3 to 8 cm. In the case of the present invention, if the number of arrays is increased to maintain the bonding strength in the total area, the appearance quality after peeling deteriorates unexpectedly.

いためのものである。In the present invention, as shown in FIG. 3, it is desirable to arrange semicircular cuts (cuts penetrating the paperboard) 15 on the opening piece. The arrangement at this time is such that the semicircular arc portion and the outer periphery of the portion to be locally joined 17 on the front plate overlap each other, and the open leg portion of the cut is opened on the opening piece 6 in one direction (from the open leg portion side). (Peeling direction) is aligned. The disposition of the semicircular cut 15 is also recognized in the conventional product.
The difference from the semi-circular cut used in the conventional product is that the conventional one needs to have a long opening leg portion because it needs to have a semi-circular shape having the same curvature as the shape drawn by the half-cut line 16 on the front plate. In contrast to the case where a large semicircular cut is required, the present invention has a circular shape with the same curvature as the shape of the portion to be locally joined 17 on the front plate, so that a short opening leg is small. It can be a semicircular cut. With that, the opening piece 6
There is an advantage that the tearing of the unsealed pieces is less likely to occur when peeling and detaching by causing. The role of the semi-circular cut 15 is to prevent the paperboard layer peeling that is about to occur on the back surface of the unsealed piece from being cut off so as not to propagate to a wide range of layer peeling.

Considering the advantage that the drying and solidifying time is short, hot-melt adhesive (common name: hot-melt adhesive)
Is preferably used. The coating amount is the amount of resin remaining on the surface of the paperboard, and is preferably a thin layer coating having a value in the range of 0.005 to 0.02 g / cm 2 .

低下させないと言う利点が生じることになる。The structure of the tear line 10 shown in FIG. 3 is for facilitating the separation of the unsealed piece. As shown in the figure, the structure is such that a large number of J-shaped cuts 10 'having long legs are arranged in series in the vertical direction with a slight interval. This role is to easily and surely cut off the unsealing piece 6 from the covering lid piece 5 when advancing the above-described peeling of the local joint portion. In other words, the J-shaped cuts 10 'are cut off by breaking the part connected at a slight interval. Therefore, this slight interval is set in the range of 0.5 to 2 mm. Since this distance is between the J-shaped tip and the J-shaped horizontal line, the remaining portion of the torn paper is lifted to the J-shaped tip side. Therefore, for example, in the case where the saw blade is fixed to the tip of the cover lid piece, the J-shaped cut 10 'is arranged in the direction in which the tip of the J-shape is directed toward the cover lid side, and the fixed position of the caulking tool of the saw blade. If one end of most of the J-shaped horizontal line is set to reach the middle of, the cutting at the cutting line 10 becomes much easier. Further, the remaining portion of the torn paper remains in the valley portion of the tooth flank protruding from the saw blade, which brings about an advantage that the saw blade is excellent in appearance and does not deteriorate the cutting performance of the saw blade.
