  The storage box 10 of this embodiment is a rectangular parallelepiped storage box that stores a tubular film winding body K formed by winding a wrap film F around a paper tube S and whose upper surface side opens and closes. The length of the film roll K in the longitudinal direction (the length in the central axis direction and the length of the paper tube S) is set to a length corresponding to the film width W of the wound wrap film F. The length in the longitudinal direction is a length commensurate with the length in the longitudinal direction (length in the central axis direction) of the film wound body K.

  The storage box 10 includes a box body 12, an openable / closable lid 14 connected to the box body 12, and a cutter 18 for cutting a drawn wrap film (hereinafter referred to as a wrap film drawer) Ff. . And the wrap film F is arrange | positioned in the inside via the open top surface T of the box main-body part 12, and the wrap film F accommodated in the box main-body part 12 of the box main-body part 12 from the front-end | tip F1. It is drawn out of the box body 12 via the open top surface T. Note that both the box body 12 and the lid 14 are made of paper.

  And the carton 20 of this embodiment is comprised by the storage box 10 and the film winding body K accommodated in this storage box 10. FIG. As shown in FIGS. 1 and 2, an unused carton 20 has a paper piece 22 connected to the distal end side of the extension lid portion 16 of the storage box 10, and a pair of side plate portions 24 p and 24 q (one of which will be described later) of the box body portion 12. The side plate portion 24p and the other side plate portion 24q) are releasably fixed to the other side plate portion 24q. The paper piece 22 continues to the extension lid portion 16 through a perforation 34. In order to use the wrap film F, the paper piece 22 is peeled off from the other side plate portion 24q of the box body portion 12 and is separated from the extension lid portion 16 along the perforation 34. A region A shown in FIG. 3 shows a fixing position of the paper piece 22 on the other side plate portion 24q of the box body portion 12. In this embodiment, the paper piece 22 extends over the cutting edge 18t so as to cover the cutting edge 18t of the cutter 18 from the extension lid portion 16.

  The wrap film F is a food packaging wrap film made of, for example, polyvinyl chloride (PVC, also referred to as vinyl chloride resin).

  The box main body 12 includes an elongated bottom plate portion 28 positioned on the lower side of the film winding body K, a pair of elongated side plate portions 24p and 24q positioned on the side of the film winding body K, and a film. The winding body K has a pair of end plate portions 32a and 32b located on both ends in the longitudinal direction, and an open top surface T is formed on the upper side. Each of the pair of end plate portions 32a and 32b has a flap 36 that prevents the accommodated film winding body K from inadvertently jumping out of the box so as to be continuous with the upper edge portion.

  The lid portion 14 is connected to one side plate portion 24p and covers the open top surface T so as to be openable and closable. And the cover part 14 has the flap-shaped extension cover part 16 which can face the other side-plate part 24q in the other side-plate part 24q side.

  The cutter 18 is bonded to a predetermined position of the outer bottom surface 28s of the bottom plate portion 28 with an adhesive, extends between the pair of end plate portions 32a and 32b in the longitudinal direction of the outer bottom surface, and extends from the inner side of the outer bottom surface to the lower end of the other side plate portion 24q. Go over the outside bottom surface. The cutter 18 has the serrated blade edge 18t on the protruding side. The cutter 18 is made of biodegradable plastic.

  Then, as shown in FIG. 4, at both ends in the cutter longitudinal direction, that is, at the longitudinal ends 18e1 and 18e2 of the cutter, the protruding adhesive portions E1 and E2 constituted by the protruding adhesive are respectively formed. Yes.

  In the present embodiment, the protruding adhesive portions E1 and E2 are bonded from the outer bottom surface 28s of the bottom plate portion 28 to the surface side of the cutter 18.

  Moreover, in this embodiment, in the container box longitudinal direction both ends, the space | interval from the outer surface of an end plate part to the cutter 18, ie, the space | interval La from the outer surface 32as of one end plate part 32a to one blade edge | tip longitudinal direction end 18a. , And the distance Lb from the outer surface 32bs of the other end plate portion 32b to the other blade edge longitudinal end 18b is a predetermined range in which the reliability with which the wrap film drawer portion Ff contacts the blade edge 18t over the entire width of the film is increased. It is stipulated in.

  This predetermined range is such that the direction P in which the wrap film drawing portion Ff is pulled is set to the central axis X of the film winding body K when the wrap film drawing portion Ff unwound from the film winding body K comes into contact with the blade edge 18t. This is also a range that is considered in the case of being inclined with respect to the orthogonal direction Y.

  Here, the wrap film drawer portion Ff has a case where the leading end side of the film is cut in a state where it is hung on a wrap target object (such as a dish on which food is placed) as the length from the film roll K increases. Many. In this case, when the wrap film drawing portion Ff is in contact with the blade edge 18t, the direction P in which the wrap film drawing portion Ff is pulled is inclined with respect to the direction Y perpendicular to the central axis X of the film winding body K. There are quite a few. And as the film width W (see FIGS. 3 and 5) of the film winding body K is larger, the drawing length tends to be longer and cut.

  When tilted in this way, the film side edge Fe is displaced at the position of the cutter 18 inward in the longitudinal direction of the blade edge or outward in the longitudinal direction of the blade edge as compared with the case of not tilting.

  Further, when such an inclination occurs, from the crossing portion C (that is, the upper end of the other side plate portion 24q of the other side plate portion 24q, see FIG. 3) of the film drawing portion Ff, the open top surface T and the other side plate portion 24q. The longer the film portion located over the distance G to the cutting edge 18t of the cutter 18, the greater the deviation of the film side edge Fe. Therefore, even if such an inclination occurs, it is preferable that the upper limit value of the predetermined range is smaller as the distance G is larger, from the viewpoint of reliably bringing the wrap film drawer portion Ff into contact with the blade edge 18t over the entire width. The distance G is determined by the number of windings of the wrap film F and the film thickness.

  As shown in FIG. 4, a portion of the storage box 10 made of paper (the box main body 12, the lid 14, the side plate 24, the end plate 32, etc.) is made of cardboard so as to have a required contour. The punched paperboard 40 is folded into a mountain fold along a fold line indicated by a thin line, and a required adhesion is made to a necessary part.

  Further, the cutter 18 is disposed at a required location on the paperboard 40 by being firmly bonded with an adhesive, so that the cutter 18 is not reliably dropped from the box body 12. As the adhesive, water glue or silicone adhesive is preferable from the viewpoint of adhesive strength, damage reduction to the carton to be attached, and convenience of handling, and the silicone adhesive is a water-soluble silicone adhesive. Further preferred.

(Function, effect)
Hereinafter, the operation and effect of the present embodiment will be described. The unused wrap film F accommodated in the storage box 10 has the box body part 12 in one hand with the cover part 14 of the storage box 10 facing up, and lifts the extension cover part 16 with the other hand. By opening the part 14, it is used. At this time, the wrap film F in the box body 12 is exposed to the outside through the open top surface T of the box body 12. In this exposed state, the user pulls out the wrap film F from the front end F1 to the outside of the box through the open top surface T of the box body 12.

  And the wrap film drawer | drawing-out part Ff pulled out from the film winding body K and exceeded on the cutter 18 is made to contact | abut over the full width of the film with the blade edge 18t of the cutter 18 arrange | positioned as an outer blade, and the blade edge 18t from one side of a film width direction. Cut with a tear.

  Here, in this embodiment, at the longitudinal ends 18e1 and 18e2 of the cutter, protruding adhesive portions E1 and E2 made of the protruding adhesive are formed. Therefore, compared with the case where the protruding adhesive portions E1 and E2 are not formed, the longitudinal ends 18e1 and 18e2 of the cutter are hardly separated from the outer bottom surface 28s. Therefore, even if the wrap film F is brought into contact with the cutter 18 and is torn many times, occurrence of peeling from the outer bottom surface 28s of the cutter 18 can be significantly suppressed.

  In FIG. 4, the protruding adhesive portions E1 and E2 are drawn in a semicircular shape, but the shape of the protruding adhesive portions E1 and E2 is not particularly limited, and is a semi-square shape or a semi-elliptical shape. It may be an irregular shape.

  Furthermore, in the present embodiment, the protruding adhesive portions E1 and E2 are bonded from the outer bottom surface 28s of the bottom plate portion 28 to the surface side of the cutter 18. Thereby, the longitudinal direction ends 18e1 and 18e2 of the cutter are further hardly peeled off from the outer bottom surface 28s. The shape of the adhesive portion bonded across the surface side of the cutter 18 is not particularly limited, and may be a semicircular shape, a semisquare shape, a semielliptical shape, an irregular shape, or the like.

  The protrusion width Bv of the protrusion adhesive portions E1 and E2 along the cutter width direction V (cutter short direction) is preferably in the range of 1/5 to 4/5 of the width of the cutter 18. If it is smaller than 1/5, it may be difficult to sufficiently obtain the effect of the protruding adhesive parts E1 and E2. If it is larger than 4/5, foreign matter may adhere to the glue that protrudes. It becomes hygienic and tends to cause poor appearance due to adhesion with other cartons.

  Further, the protrusion length Bu of the protrusion adhesive parts E1 and E2 along the cutter longitudinal direction U is preferably in the range of 1/5 to 4/5 of the width of the cutter 18. If it is smaller than 1/5, it may be difficult to sufficiently obtain the effect of the protruding adhesive parts E1 and E2. If it is larger than 4/5, foreign matter may adhere to the glue that protrudes. It becomes hygienic and tends to cause poor appearance due to adhesion with other cartons.

  Further, as described above, the distance La from the outer surface 32as of one end plate portion 32a to one blade edge longitudinal end 18a, and the outer surface 32bs of the other end plate portion 32b to the other blade edge longitudinal end 18b. The intervals Lb are all defined within the predetermined range.

  Therefore, the certainty that the wrap film F pulled out from the box abuts against the blade edge 18t of the cutter 18 over the entire width of the cutter 18 is greatly increased as compared with the prior art, so that the blade edge longitudinal ends 18a, 18b of the cutter 18 are the wrap film surface. It is prevented from being cut in contact with the inside. This has a great effect in terms of obtaining a good film cutting shape and reducing the load on the cutter 18. This effect becomes more prominent as the film width W is larger.

  In addition, when the cutter 18 is made of biodegradable plastic, if a large force acts on the blade edge longitudinal end 18a or the blade edge longitudinal end 18b, the cutter 18 adhered to the outer bottom surface 28s is easily peeled off from the outer bottom surface 28s. The ability to reduce the load on the cutter 18 is very preferable from the viewpoint of extending the life of the storage box 10. Moreover, in this embodiment, since the cutter 18 is made of biodegradable plastic and not metal, it is not necessary to remove the cutter in the disposal process of the carton 20, and the time and equipment required for the disposal process are greatly reduced. In addition, the risk of injury during removal of the metal cutting blade is eliminated.

  When the film width W in the film winding body K is in the range of 218 to 224 mm, the predetermined range (interval) is preferably in the range of 4 to 10 mm from the viewpoint of further increasing the certainty. If the predetermined range is longer than 10 mm, the blade edge longitudinal end 18a and the blade edge longitudinal end 18b may easily come into contact with the wrap film surface during film cutting. Shrinkage may occur and the intended coating may not be achieved. When the predetermined range is shorter than 4 mm, an unnecessary cutter part is generated, and work efficiency may be deteriorated by transportation and use of the carton 20. The thickness t of the end plate portions 32a and 32b is usually about 2 to 3 mm, and the distance between the width direction end FKe of the wrap film F and the lengthwise end Se of the paper tube S in the film winding body K. For example, D is about 4 mm.

  In this case, when the distance G from the intersection C between the open top surface T and the other side plate portion 24q to the blade edge 18t is in the range of 45 to 50 mm, the predetermined range (interval) is in the range of 4 to 7 mm. Is preferable from the viewpoint of further increasing the certainty.

  In addition, the range example whose film width W is 218-224 mm is an example, and of course, it is applicable also to the thing of film widths other than this (for example, a long film width is 300 mm, 450 mm, or more).

  The number of windings of the wrap film F in the film winding body K is, for example, 30 m, 50 m, 55 m, 60 m, 100 m, and 110 m. When the wrap film thickness is the same, the distance G increases as the number of windings increases.

  Moreover, the material of the wrap film F is polyvinyl chloride (PVC), which is excellent in adhesion, transparency, anti-fogging property, cost merit, etc. Also, film strength, film cutting property, film productivity It is preferable from the viewpoints.

  Moreover, the component of the cutter 18 may contain titanium dioxide. Titanium dioxide can impart water repellency to the cutter 18 depending on the mixing conditions, thereby further reducing the biodegradability of the biodegradable plastic constituting the cutter 18 and further increasing the usable period of the cutter 18. Can be increased. This mixing condition can be arbitrarily selected.

  Further, in the present embodiment, an example in which the blade edge 18t has a sawtooth shape has been described. However, as long as the wrap film F can be cut satisfactorily, a shape other than a sawtooth shape may be used. For example, FIG. 5 illustrates an example in which the blade edge 18t has an acute angle, but a biodegradable plastic cutter whose blade edge 18t has an obtuse angle may be used as a storage box bonded to the bottom plate portion.

  According to the present invention, even a carton with a short wrap film width, which is increasing in demand, is convenient to use, and can be applied in a wide range of fields when packaging an article to be packaged such as food.
