The temporary fastening part 40 is formed in the widthwise direction of the wrap film F, and at least a central part C of the temporary fastening part 40 in the widthwise direction of the wrap film R is so formed that the adhesive property to the wrap film F becomes weaker toward a cut end F1 of the wrap film F.

Description

  The present invention relates to a wrap film storage box for storing a wound film of a wrap film, an aluminum foil, a cooking sheet or the like (hereinafter referred to as “wrap film”) for food packaging.

  The wrap film is usually wound around a paper core to form a tubular film roll, and in that state, the wrap film is stored in a paper cuboid wrap film storage box. Usually, a cutting part such as a metal, paper or resin saw blade for cutting the wrap film drawn from the film winding body is provided at the tip of the lid piece of the wrap film storage box.

  By the way, after cutting a wrap film, the wrap film remaining after cutting may be rewound onto the film winding body in the storage box. Thus, when the wrap film is rewound, it takes time to peel off and pull out the leading end portion of the wrap film again at the next use, which greatly impairs the usability. In view of this, it has been proposed to provide a temporary fastening portion for adhering and temporarily fastening the wrap film remaining after cutting to the front plate of the wrap film storage box (see Patent Documents 1 and 2).

  In the technique described in Patent Document 1, a band-like temporary fixing portion that extends over both ends of the front plate is formed, and the temporary fixing portion includes a notch portion having a narrow width at three locations, that is, a longitudinal center portion and both longitudinal end portions. Is provided. Further, in the technique described in Patent Document 2, the film holding portion is provided with a gap on both sides of the first holding portion applied to the center portion in the width direction of the front plate, and both sides of the first holding portion, and A streaky second holding portion applied to the left and right end portions of the front plate of the case body is provided.

Japanese Patent No. 3195468 JP 2005-212894 A

  However, since the cut end of the wrap film cut by the cutting part is likely to be torn or scratched, when the wrap film is peeled off from the temporary fastening part, the wrap film may be torn starting from the tear or scratch. Therefore, the device which prevents a wrap film from tearing when peeling a wrap film from a temporary fixing part is required. Most people unconsciously pinch around the center of the wrap film when peeling off the wrap film, but in the case of the above-mentioned Patent Document 1, when picking around the center of the wrap film and trying to peel it off from the temporary fastening portion The force is applied intensively to the cut end of the wrap film projecting to the bottom plate side of the temporary fastening portion, and the wrap film may be torn from that portion.

  In the box of the above-mentioned patent document 2, when it is going to peel a wrap film from a temporary fixing part, since it is necessary to peel a wrap film against the strong adhesive force of a temporary fixing part from the beginning, a wrap film is easy to tear.

  The present invention has been made in view of the above points, and while temporarily preventing the wrap film from being unwound at the temporary fixing portion, pinching the central portion of the wrap film at the next use so as not to tear the wrap film. It is an object of the present invention to provide a wrap film storage box that can be peeled from a part.

As a result of intensive studies, the inventor has found that the above-described various problems can be solved by weakening the adhesiveness of the temporary fastening portion to the wrap film toward the cut end of the wrap film, thereby forming the present invention. It came to. That is, the present invention provides the following (1) to (4).
(1) A wrap film storage box for storing a tubular film winding body of a wrap film, which is formed on a surface of the storage box, a cutting portion for cutting the wrap film drawn from the film winding body, A temporary fastening portion for temporarily fastening the wrap film of the film winding body remaining after being cut by the cutting portion, and the temporary fastening portion is formed in the width direction of the wrap film, and the temporary fastening portion A wrap film storage box, wherein at least a central portion of the wrap film in the width direction is formed such that adhesiveness to the wrap film becomes weaker toward a cut end of the wrap film.
(2) In at least three regions at the center when the temporary fastening portion is divided into seven equal parts in the width direction of the wrap film, the adhesiveness to the wrap film becomes weaker toward the cut end of the wrap film. The wrap film storage box according to (1).
(3) Adhesiveness to the wrap film is weakened toward the cut end of the wrap film in all the regions when the temporary fixing portion is divided into seven equal parts in the width direction of the wrap film. ) Or the wrap film storage box according to (2).
(4) At least a part of the temporary fastening portion has a shape that becomes narrower toward the cut end of the wrap film, and the temporary shape with respect to the wrap film is arranged by arranging the shape in the width direction of the wrap film. The wrap film storage box according to any one of (1) to (3), wherein the adhesiveness of the fastening portion is weak.
(5) The wrap film storage box according to (4), wherein a leading end of the shape that becomes narrower toward the cut end of the wrap film is directed toward the center side of the wrap film.
(6) At least a part of the temporary fixing portion has a shape composed of a plurality of points, the density of the number of the plurality of points is lowered toward the cut end of the wrap film, and / or the plurality of the plurality of points. The wrap film storage box according to any one of (1) to (3), wherein the adhesiveness of the temporary fastening portion to the wrap film is weakened by reducing the area per point.
(7) The wrap film storage box according to any one of (1) to (6), wherein the temporary fixing portion is formed of a UV-curing varnish.

  The wrap film storage box of the present invention prevents the wrap film after being cut back into the wrap film storage box and easily peels off at the initial stage of peeling when the cut end side of the temporarily attached wrap film is pinched. Because the distance from the cut end of the wrap film is farther when the area above the temporary fixing portion for facilitating the gripping property and positively preventing rewinding is removed, the cut end of the wrap film becomes longer. The resistance for tearing is difficult to be applied, and the trouble of tearing the wrap film can be prevented. Also, when repairing the trouble that the wrap film is torn, the finger hits the cutting edge of the cutting tool and sometimes injured the finger, but since the trouble that tears the wrap film itself can be prevented, work to repair the trouble is necessary. So it wo n’t hurt your fingers.

  As shown in FIGS. 1 and 2, the wrap film storage box 1 has a rectangular parallelepiped shape as a whole. For example, a lid 13 including a lid piece 10, a lid plate 11, a side lid piece 12, a front plate 14, and a bottom plate. 15, the storage part 19 which consists of the back board 16, the side board 17, the folding | turning piece 18, etc. and the opening piece 20 are provided. Note that the folded piece 18 is folded back to the back surface (inner surface) side of the front plate 14 and does not appear on the appearance.

  As shown in FIG. 3, the storage unit 19 is formed in a rectangular parallelepiped shape having an upper surface opening 19a. For example, a film roll R in which a transparent wrap film F is wound around a cylindrical core is stored from the upper surface opening 19a. it can.

  As shown in FIG. 1, the lid plate 11 of the lid portion 13 extends forward from the upper end edge of the rear plate 16 and covers the upper surface opening 19 a of the storage portion 19. The lid cover piece 10 extends from the front edge of the cover plate 11 toward the front plate 14 and covers the front surface of the front plate 14.

  Examples of the base paper constituting the wrap film storage box 1 include, but are not limited to, cardboard, coated cardboard, cardboard, and the like, and papers known in the industry are appropriately selected and used. Can do. The base paper may be one obtained by embossing, printing, or laminating using polyethylene or the like on these materials.

  The opening piece 20 is located in the lower part of the front surface of the front plate 14 of the storage unit 19 and is formed in a strip shape along the longitudinal direction of the wrap film storage box 1. The unsealing piece 20 is connected to the tip edge of the lid cover piece 10 via a cut line 21. Before opening, the back side of the opening piece 20 is bonded to the plurality of bonding portions 22 of the front plate 14 shown in FIG. The lid portion 13 is sealed by the opening piece 20, and the lid portion 13 can be opened by cutting the opening piece 20 along the cut line 21 as shown in FIG. 4.

  As shown in FIGS. 3 and 4, a saw blade 30 as a cutting portion for cutting the wrap film F drawn from the film winding body R of the storage portion 19 is provided on the back side of the distal end portion of the lid piece 10. Yes. The saw blade 30 is formed across both longitudinal ends of the wrap film storage box 1 (the lid piece 10). The saw blade 30 is formed at a position protruding downward from the tip edge of the lid cover piece 10 when the opening piece 20 is cut off. At the front end of the wrap film F cut by the saw blade 30, a cut end F1 is formed. The material of the cutting portion such as the saw blade 30 is metal, plastic, vulcanized fiber, etc., and the shape of the cutting portion is not particularly limited as long as it is a conventionally known one such as a straight shape, a V shape, and an arch shape. .

  As shown in FIGS. 2 and 3, a temporary fastening portion 40 for temporarily fastening the wrap film F of the film roll R remaining after cutting is formed on the surface of the front plate 14. The temporary fixing portion 40 is formed of, for example, a UV curable varnish and has adhesiveness. The temporary fastening portion 40 is continuously formed along the longitudinal direction (the width direction of the wrap film F) across both end portions in the longitudinal direction of the wrap film storage box 1. The temporary fastening portion 40 is formed, for example, up to both ends within 20 mm from both ends of the front plate 14. For example, as shown in FIG. 5, the temporary fastening portion 40 is entirely formed in a band shape, and the central portion C in the longitudinal direction has an adhesiveness to the wrap film F with respect to the cut end F <b> 1 (the lower side of the front plate 14). ) Is formed to become weaker.

  Specifically, the central portion C of the temporary fixing portion 40 includes a base portion 40a having the same width extending along the longitudinal direction (X direction in FIG. 5) of the front plate 14, and a wrap film of the base portion 40a. It is provided on the side of the cutting end F1 and is composed of a triangular shaped body 40b that becomes narrower toward the cutting end F1. A plurality of the shape bodies 40b are arranged in the longitudinal direction of the front plate 14, and the lower end of the central portion C has a zigzag shape (saw shape). The central portion C is composed of three regions C1, C2, and C3 that are close to the center when the temporary fixing portion 40 is divided into seven equal parts in the longitudinal direction of the front plate 14. Therefore, in each of these three narrow central regions C1, C2, and C3, the area decreases toward the cut end F1 side of the wrap film F, and the adhesiveness decreases. Conversely, in each of the central regions C1, C2, and C3, the area increases from the cut end F1 side of the wrap film F toward the upper end side of the front plate 14, and the adhesiveness increases. Within each central region C1, C2, C3, a plurality of identical features 40b are repeated. The side portions S on both sides of the central portion C of the temporary fastening portion 40 are formed with a constant vertical width. For example, the vertical width of the central region C and the side portion S is the same.

  The wrap film F after being cut is attached and temporarily fixed to the temporary fixing portion 40 disposed on the front plate 14. Then, at the next use, the center portion of the wrap film F is pinched, the wrap film F is peeled off from the temporary fastening portion 40, stretched to a desired length, and the wrap film F is cut by the saw blade 30 with the lid portion 13 closed. .

  According to this Embodiment, since the adhesiveness with respect to the wrap film F of the center part C of the temporary fixing part 40 is weakening toward the cutting | disconnection end F1, the center of the wrap film F is pinched and it is from the temporary fixing part 40. When peeling off, the adhesive force of the temporary fastening part 40 is weak at first, and it is easy to pinch the cutting end F1 near the center of the wrap film F, and the wrap film F can be peeled off from the temporary fastening part 40 without resistance. Therefore, even if the cut end F1 of the wrap film F has a scratch or the like made by the saw blade 30, it is possible to prevent the wrap film F from tearing from the scratch when peeling off from the temporary fastening portion 40. Moreover, since there exists sufficient adhesive force in the upper part of the direction which leaves | separates from the cutting end F1 of the wrap film F of the temporary fixing part 40, the rewinding of the wrap film F can be prevented. In addition, even if there is adhesive force on the upper part of the temporary fastening part 40, since there is a distance from the cut end F1 of the wrap film F, no tearing occurs from the cut part F1. Thus, while preventing the wrap film F from being unwound by the temporary fastening portion 40, the wrap film F can be peeled from the temporary fastening portion 40 so as not to tear, by pinching the central portion of the wrap film F at the next use.

  In addition, when adhesiveness evaluation of the temporary fastening part 40 and the wrap film F was performed, even when the temporary fastening part 40 was formed so that it might become weak toward the cut end F1 of the wrap film F, the wrap film F was picked temporarily. At the time of peeling from the fastening portion 40, the adhesive strength of the temporary fastening portion 40 is initially weak, but the upper portion away from the cut end F1 has sufficient adhesive strength to prevent rewinding.

  Moreover, in the said embodiment, the adhesiveness with respect to the wrap film F is the cutting end F1 in each of three area | region C1, C2, C3 of the center part when the temporary fixing part 40 is divided into 7 equally in the width direction of the wrap film F. Therefore, the wrap film F can be suitably peeled while making it easy to pinch the central portion of the wrap film F.

  In addition, the area | region which weakens the adhesiveness with respect to the wrap film F toward the cut end F1 may be five areas | regions of the center when the temporary fixing part 40 is divided into 7 equally. For example, as shown in FIG. 6, the adhesiveness to the wrap film F may be weakened toward the cut end F <b> 1 in all regions when the temporary fixing portion 40 is divided into seven equal parts.

  In the said embodiment, since the form 40b which becomes narrow toward the cutting | disconnection end F1 of the wrap film F was arranged, and the adhesiveness of the temporary fixing part 40 was weakened toward the cutting part F1, the wrap film F from the temporary fixing part 40 is made. The feeling of peeling off changes continuously, and the operation of the wrap film F becomes easy.

  Moreover, as shown in FIG. 7, the front-end | tip of the shape 40b which becomes narrow toward the cut end F1 of the wrap film F may be orient | assigned to the center P side of the wrap film F. When pinching near the center of the wrap film F and peeling it off from the temporary fastening portion 40, the wrap film F is peeled off radially from the knob position, so the front end of the shape 40b faces the center P side of the wrap film F. Thus, the tearing of the wrap film can be more effectively suppressed. At this time, since the radial center is derived from the knob position, it may not be a single point due to the size of the hand, but the center in the width direction (longitudinal direction of the front plate 14) of the cut end F1 of the wrap film. The range is preferably within 15 cm from P.

  Moreover, in the said embodiment, although the adhesiveness of the temporary fixing part 40 was weakened toward the cutting | disconnection part F1 with the triangular-shaped form 40b, it is not restricted to this, The adhesiveness of the temporary fixing part 40 with another form May be weakened.

  For example, as shown in FIG. 8, the front end of the shape 40b that becomes narrower toward the cutting end F1 may be flat (the shape 40b is trapezoidal). Moreover, as shown in FIG. 9, the curved shape may be sufficient between adjacent taper-shaped bodies 40b.

  Further, as shown in FIG. 10, the shape 40b may be composed of a plurality of circular points. In this case, each point may have the same diameter, and the density of the number of the points may decrease toward the cut end F1 of the wrap film F. Moreover, you may make the area per point of several points small toward the cutting end F1. Moreover, you may combine these points.

  The shape 40b is not limited to these, and may have other shapes and arrangements. In addition, the upper portion of the base portion 40a except for the shape 40b portion of the temporary fastening portion 40 has the same adhesive strength in the film width direction, for example, the same width, in order to positively develop a locking function. Good. In this case, the width of the same width portion is preferably 10 mm or less. If it is such a range, it will be easy to balance between preventing the wrap film F from rewinding to the storage part 19 and facilitating the peeling of the wrap film F in the next use. Moreover, the adhesive strength of the upper part of the temporary fixing part 40 may not be the same in a film width direction.

  In addition, the means for achieving that the adhesiveness of the temporary fastening portion 40 of the present invention to the wrap film F becomes weaker as it goes downward is not particularly limited. For example, the material is used in the temporary fastening portion 40. The method of changing may be used.

  In the above embodiment, the temporary fixing portion 40 is formed of UV-cured varnish, but it is not particularly limited to this, and even if it is an adhesive type such as an adhesive resin, it is non-adhesive. A self-adhesive type such as surface smoothing may be used.

  Moreover, in the above embodiment, you may provide the knob piece 50 which floats ahead on the front board 14, as shown in FIG. The knob piece 50 is formed, for example, by making a notch 51 in the front plate 14, and is lifted by a reaction caused by folding the folded plate 18 to the back side of the front plate 14. The combined use of such a mechanism and the temporary fastening portion 40 in the present invention makes it easier to pinch the wrap film F.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious for those skilled in the art that various modifications or modifications can be conceived within the scope of the idea described in the claims, and these naturally belong to the technical scope of the present invention. It is understood.

  INDUSTRIAL APPLICABILITY In the wrap film storage box, the present invention is useful for suppressing tearing of the wrap film when peeling from the temporary fastening portion while preventing the film from rewinding.
