The accommodation box 10 of the present embodiment is a rectangular parallelepiped accommodation box that accommodates a tubular film winding body K formed by winding a wrap film F around a paper tube S and opens and closes the upper surface side. The length in the longitudinal direction of the film winding body K (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 wrapped wrap film F, and The length in the longitudinal direction is set to a length corresponding to the length in the longitudinal direction (length in the central axis direction) of the film winding 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 drawing section) Ff. .. Then, the wrap film F is disposed inside the box body 12 via the open top surface T of the box body 12, and the wrap film F accommodated in the box body 12 extends from the tip F1 thereof to the box body 12. It is adapted to be drawn out of the box body 12 via the open top surface T. The box body 12 and the lid 14 are both made of paper.

Then, the carton 20 of the present embodiment is configured by the accommodation box 10 and the film winding body K accommodated in the accommodation box 10. As shown in FIG. 1 and FIG. 2, in the unused carton 20, a paper piece 22 continuous to the tip side of the extension lid portion 16 of the storage box 10 has a pair of side plate portions 24p and 24q (one Of 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 is connected to the extension lid portion 16 via perforations 34. Due to the use of 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 cut off from the extension lid portion 16 along the perforations 34. A region A shown in FIG. 3 indicates a fixing portion of the paper piece 22 on the other side plate portion 24q of the box body portion 12. In the present 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 wrap film for food packaging made of, for example, polyvinyl chloride (PVC, also called vinyl chloride resin).

The box body 12 includes an elongated bottom plate portion 28 located below the film winding body K, a pair of elongated side plate portions 24p and 24q located on the lateral side of the film winding body K, and a film. The wound 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 continuous with the upper edge portion thereof for preventing the contained film winding body K from accidentally jumping out of the box.

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. The lid portion 14 has a flap-shaped extension lid portion 16 that can face the other side plate portion 24q on the other side plate portion 24q side.

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

Then, as shown in FIG. 4, at both ends of the cutter in the longitudinal direction, that is, at the longitudinal ends 18e1 and 18e2 of the cutter, squeeze-out adhesive portions E1 and E2 composed of the squeezed out adhesive are formed, respectively. There is.

In the present embodiment, the squeeze-out adhesive portions E1 and E2 are adhered to each other over the outer bottom surface 28s of the bottom plate portion 28 and the front surface side of the cutter 18.

Further, in the present embodiment, at both end portions in the longitudinal direction of the storage box, the distance from the outer surface of the end plate portion to the cutter 18, that is, the distance La from the outer surface 32as of the one end plate portion 32a to the one end 18a of the cutting edge longitudinal direction. , And the interval Lb from the outer surface 32bs of the other end plate portion 32b to the other blade edge longitudinal direction end 18b is a predetermined range in which the certainty that the wrap film pull-out portion Ff contacts the blade edge 18t over the entire width of the film Stipulated in.

This predetermined range is such that when the wrap film drawing-out portion Ff unwound from the film winding body K contacts the cutting edge 18t, the pulling direction P of the wrap film drawing-out portion Ff is aligned with the central axis X of the film winding body K. The range is also considered when it is inclined with respect to the orthogonal direction Y.

Here, the wrap film pull-out portion Ff may be cut in a state where the leading end side of the film is hung on a wrapping object (such as a plate on which foodstuffs are placed) as the pull-out length from the film winding body K is longer. Many. In this case, when the wrap film pull-out portion Ff contacts the cutting edge 18t, the pulling direction P of the wrap film pull-out portion Ff is inclined with respect to the direction Y orthogonal to the central axis X of the film winding body K. Is quite a lot. The larger the film width W (see FIGS. 3 and 5) of the film winding K, the longer the drawing length and the more likely the film is wound.

With such an inclination, the film side edge Fe is positioned at the position of the cutter 18 so as to be displaced inward in the longitudinal direction of the cutting edge or outside in the longitudinal direction of the cutting edge, as compared with the case where it is not inclined.

Further, when such an inclination occurs, in the film pull-out portion Ff, from the intersection C between the open top surface T and the other side plate portion 24q (that is, the upper end of the other side plate portion 24q, see FIG. 3). The longer the film portion located over the distance G to the blade edge 18t of the cutter 18, the larger the above-mentioned deviation of the film side edge Fe. Therefore, from the viewpoint of surely contacting the wrap film pull-out portion Ff with the cutting edge 18t over the entire width even if such an inclination occurs, it is preferable that the upper limit value of the predetermined range be smaller as the distance G is larger. The distance G is determined by the number of windings of the wrap film F and the film thickness.

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

Further, the cutter 18 is arranged at a desired position on the paper board 40 by being strongly adhered thereto with an adhesive, so that the cutter 18 is prevented from surely coming off from the box body 12. As the adhesive, water glue or silicone adhesive is preferable from the viewpoint of adhesive strength, reduction of damage to the carton to be attached, and convenience of handling, and the silicone adhesive is a water-soluble silicone adhesive. More preferable.

(Action, effect)
The operation and effect of this embodiment will be described below. The unused wrap film F stored in the storage box 10 holds the box body 12 in one hand with the cover 14 of the storage box 10 facing upward, and the extension cover 16 is pulled up by the other hand to cover it. By opening the part 14, it is ready for use. At this time, the wrap film F in the box body 12 is exposed to the outside by the open top surface T of the box body 12. In this exposed state, the user pulls the wrap film F out of the box from the front end F1 through the open top surface T of the box body 12.

Then, the wrap film pull-out portion Ff pulled out from the film winding body K and over the cutter 18 is brought into contact with the blade edge 18t of the cutter 18 arranged as an outer blade over the entire width of the film, and the blade edge 18t is fed from one side in the film width direction. Cut with tearing.

Here, in the present embodiment, the protruding adhesive portions E1 and E2 formed of the protruding adhesive are formed at the longitudinal ends 18e1 and 18e2 of the cutter, respectively. Therefore, the longitudinal ends 18e1 and 18e2 of the cutter are significantly less likely to be peeled from the outer bottom surface 28s, as compared with the case where the protruding adhesive portions E1 and E2 are not formed. Therefore, even if the wrap film F is brought into contact with the cutter 18 and is torn a number of times, the occurrence of peeling from the outer bottom surface 28s of the cutter 18 can be significantly suppressed.

In addition, 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 half square shape or a semielliptical shape. Alternatively, it may have an irregular shape or the like.

Further, in the present embodiment, the squeeze-out adhesive portions E1 and E2 are adhered to each other over the outer bottom surface 28s of the bottom plate portion 28 and the front surface side of the cutter 18. As a result, the longitudinal ends 18e1 and 18e2 of the cutter are more difficult to peel off from the outer bottom surface 28s. The shape of the adhesive portion that is adhered over the front surface side of the cutter 18 is not particularly limited, and may be a semicircular shape, a semisquare shape, a semielliptical shape, a distorted shape, or the like.

The protruding width Bv of the protruding adhesive portions E1 and E2 along the cutter width direction V (shorter cutter direction) is preferably in the range of 1/5 to 4/5 of the width of the cutter 18. If it is smaller than ⅕, it may be difficult to sufficiently obtain the effect of the squeezed-out adhesive parts E1 and E2, and if it is larger than 4/5, foreign matter may adhere to the squeezed-out glue, and It becomes hygienic and easily adheres to other cartons to cause poor appearance.

Further, the protruding length Bu of the protruding adhesive portions 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 ⅕, it may be difficult to sufficiently obtain the effect of the squeezed-out adhesive parts E1 and E2, and if it is larger than 4/5, foreign matter may adhere to the squeezed-out glue, and It becomes hygienic and easily adheres to other cartons to cause poor appearance.

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

Therefore, the certainty that the wrap film F pulled out from the box is brought into contact with the blade edge 18t of the cutter 18 over the entire width of the film is significantly higher than in the conventional case, and therefore, the blade edge longitudinal ends 18a and 18b of the cutter 18 are located on the lap film surface. It is prevented that it abuts inside and is cut. This brings about a great effect from the viewpoint of obtaining a good film cutting shape and reducing the load on the cutter 18. Further, this effect becomes more remarkable as the film width W is larger.

In addition, when the cutter 18 is made of biodegradable plastic, when a large force acts on the cutting edge longitudinal direction end 18a and the cutting edge longitudinal direction end 18b, the cutter 18 adhered to the outer bottom surface 28s is easily separated 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. Further, in the present embodiment, since the cutter 18 is made of biodegradable plastic and not made of metal, it is not necessary to remove the cutter when disposing of the carton 20, and the time and equipment required for the disposal process are greatly reduced. Moreover, the risk of injury when removing 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, it is preferable that the predetermined range (interval) is in the range of 4 to 10 mm from the viewpoint of further increasing the certainty. When the predetermined range is longer than 10 mm, the blade edge longitudinal direction end 18a or the blade edge longitudinal direction end 18b may easily come into contact with the wrap film surface during the film cutting, and the width direction of the wrap film may be increased when the film is pulled out. Shrinkage may occur and the intended coating may not be possible. If the predetermined range is shorter than 4 mm, an unnecessary cutter portion may be generated and work efficiency may be deteriorated when the carton 20 is transported or used. In addition, the thickness t of the end plate portions 32a and 32b is usually about 2 to 3 mm, and the distance between the widthwise end FKE of the wrap film F and the longitudinal end Se of the paper tube S in the film winding body K. D is, for example, 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 cutting edge 18t is in the range of 45 to 50 mm, this predetermined range (interval) is in the range of 4 to 7 mm. However, it is preferable from the viewpoint of further increasing the certainty.

Note that the range of the film width W of 218 to 224 mm is an example, and it is of course applicable to other film widths (for example, long film widths of 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, 110 m. When the wrap film thickness is the same, the value of the distance G increases as the number of windings increases.

In addition, the fact that the material of the wrap film F is polyvinyl chloride (PVC) is excellent in adhesion, transparency, antifogging property, cost merit, etc., and also film strength, film cutting property, and film productivity. From the viewpoint of the above, it is preferable.

Further, the component of the cutter 18 may include titanium dioxide. Titanium dioxide can impart water repellency to the cutter 18 depending on the mixing conditions thereof, thereby suppressing the biodegradability of the biodegradable plastic constituting the cutter 18 to further extend the usable period of the cutter 18. Can be increased. This mixing condition can be arbitrarily selected.

Further, in the present embodiment, the example in which the cutting edge 18t has a saw-tooth shape has been described, but as long as the wrap film F can be satisfactorily cut, a shape other than the saw-tooth can be used. For example, although FIG. 5 illustrates an example in which the cutting edge 18t has an acute angle shape, a biodegradable plastic cutter having the cutting edge 18t having an obtuse angle may be used as a housing box in which the bottom plate portion is adhered.

INDUSTRIAL APPLICABILITY According to the present invention, even a carton with a short wrap film width, which has been in high demand, is easy to use, and therefore, it can be applied in a wide range of fields for packaging objects to be packaged such as food.
