Description

  The present invention relates to a wrap film storage carton that stores a wrap film wound in a roll shape, and more particularly, to an improvement technique for a function of preventing a wrap film end from being unwound from the wrap film storage carton.

  Conventionally, wrap film storage cartons that store rolls of wrap film wound in a long length have been widely used. In this wrap film storage carton, the roll-shaped wrap film stored inside the carton is pulled out to a desired length and pressed between the front plate of the carton body and the lid piece of the lid that covers this front plate. The wrap film in a state of being cut is used by cutting with a cutting blade. At this time, the end of the wrap film that will be the most advanced when it is next pulled out often does not remain on the outside of the carton without being pulled out, and often rolls back inside the carton, Making it difficult. In order to prevent this rewinding, various wrapping film storage cartons have been proposed in which some type of rewinding prevention function is provided on the front plate pressed when the wrapping film is cut.

  As this unwinding prevention function, for example, a wrap film holding portion made of a pressure sensitive adhesive layer is provided on the front plate constituting the carton for storing the wrap film, and the lid cover piece is overlapped at a position covering the front plate. A method of exposing the pressure-sensitive adhesive layer to the surface of the carton when the continuous opened pieces are removed by peeling, and holding the wrap film edge after cutting by the pressure-sensitive adhesive layer to prevent rewinding. is there.

In addition, a wrap film holding portion made of a flat resin coating layer is provided on the surface of the front plate where the front plate of the carton and the lid cover piece provided at a position covering the front plate overlap, and the coating layer is smooth. There is also a method of holding using the self-adhesiveness of the wrap film to the surface (for example, see Patent Document 1).
JP-A 64-9151

  However, in the conventional method as described above, for example, in the case of the wrap film holding portion made of the first pressure-sensitive adhesive layer, if the adhesive force of the adhesive itself is too strong, the wrap film adheres too strongly, and the wrap film When pulling out the film, the wrap film is cut, and the pressure-sensitive adhesive layer gradually has dust and dust attached thereto.

  In addition, a method of holding a wrap film holding part cloth layer made of a flat resin coating layer on the surface of the front plate of the carton and holding the wrap film using its smoothness is a self-adhesive polyvinylidene chloride, etc. However, this wrap film has a problem that it is difficult to peel off due to too close contact.

  The present invention has been found to solve the above-described problems. The object of the present invention is to provide a wrap film holding portion for preventing the wrap film end from being rewound into the carton after cutting. Provided with a coated layer of resin that has good adhesion to the film, and further provided a wrap film storage carton that has been improved so that the wrap film holding part is in close contact with the film and is easy to peel off and easy to remove. There is to do.

  The present invention has been made to solve the above-mentioned problems. A lid body is connected to one side edge of an opening of a carton main body in which a wrap film wound in a roll shape is stored so as to be freely opened and closed. In the wrap film storage carton that presses the drawn wrap film between a front plate and a lid cover piece of the lid provided at a position covering the front plate, and cuts it with a cutting blade, at least the front plate A wrap film comprising a wrap film holding portion made of a resin coating layer on a part or all of the lap film covering portion, and a plurality of convex portions formed on a part or all of the wrap film holding portion. A storage carton is characterized in that the shape of the base of the convex portion is circular, elliptical, or oval.

  The wrap film storage carton of the present invention is provided with a wrap film holding portion made of a resin coating layer on the surface of the front plate in order to prevent the end of the wrap film drawn out during use from being rolled back into the carton. By providing a plurality of convex portions on all or part of the film holding portion, the wrap film holding portion has good adhesion to the taken out wrap film and peels off the wrap film when it is used again. It has the effect that it can be pulled out easily. Specifically, the wrap film drawn out on the upper surface of the plurality of convex portions provided in whole or in part of the wrap film holding portion can be appropriately adhered, can prevent rewinding, and when used again, The weak adhesion part between a convex part and a convex part can be peeled off as a handle, and a wrap film can be pulled out easily.

  Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. In the wrap film storage carton of the present invention, a wrap film holding portion made of a resin coating layer is provided on the surface of the front plate, and a plurality of convex portions are provided on all or part of the wrap film holding portion. The part of the wrap film holding part differs depending on the shape of the carton, specifically the attachment position of the cutting blade for cutting the wrap film. After the wrap film is pulled out from the carton body and cut, Any surface can be used as long as it is in contact with the carton and is not particularly limited. However, in general, when cutting the wrap film, the wrap film is sandwiched between the front plate of the carton body and the gutter lid piece where the front plate overlaps, and cut while pressing from the outside. It is easily pressed against the front plate. Therefore, the wrap film holding part is provided at a position where the wrap film on the front plate surface is sandwiched. Further, the size and shape of the wrap film holding portion are free, and may be freely determined so that the function of holding the wrap film is stabilized depending on the material of the wrap film, the carton shape, or the attachment position of the cutting blade.

  1, 4, and 5, typical examples of wrap film storage cartons having different wrap film cutting blade shapes and attachment positions are given. When cutting, it is preferable to be in an area including a position where the wrap film is strongly pressed against the carton surface, and as a result, the wrap film is naturally pressed against the wrap film holding portion and closely adhered by the operation of cutting the wrap film. , Will be held.

The blank 10 of the wrap film storage carton A has a front plate 11, a bottom plate 12, a rear plate 13 and a cover plate 14 which are continuously provided via folding lines a, b and c, as shown in the figure. A fold piece 17 is connected to the side edge of the front plate 11 via a fold line e, and a lid cover piece 15 is connected to the side edge of the cover plate 14 via a fold line d. An opening piece 16 is connected to the lid cover piece 15 through a cut line L. The opening piece 16 can be separated by the cut line L. The cut line L is formed in a form that is easy to cut, such as a perforation or a lead rule. The opening piece 16 is formed with a plurality of semicircular cuts 23 in the same direction at equal intervals along the longitudinal direction.

  The first side pieces 18 and 18 ′ and the side plates 19 and 19 ′ are respectively provided at both end positions of the front plate 11, the bottom plate 12, the rear plate 13, the cover plate 14 and the lid cover piece 15 via folding lines f and f ′. The second side pieces 20 and 20 ′, the side lid plates 21 and 21 ′, and the side lid pieces 22 and 22 ′ are connected in series. Here, the lengths of the side plates 19 and 19 ′ are substantially the same as the widths of the front plate 11 and the rear plate 13, and the lengths of the first side pieces 18 and 18 ′ and the second side pieces 20 and 20 ′ are the side plates. 19 and 19 '. Further, the length of the side cover plates 21 and 21 ′ is substantially half of the length of the side plates 19 and 19 ′, and the length of the side cover pieces 22 and 22 ′ is shorter than the width of the cover plate 14. Yes.

  Further, as shown in FIG. 2, the front plate 11 has a circular shape having the same diameter as that of the notch 23 at a position in contact with the semicircular notch 23 of the opening piece 16 when formed in the wrap film storage carton A. A half-cut portion 24 is provided. And in the wrap film accommodation carton of this invention, the wrap film holding | maintenance part P which prevents the rewinding in the carton of the wrap film end is provided.

  The wrap film holding portion P is coated with a resin having good adhesion to the wrap film to form a coating layer. Examples of the resin used include silicon-modified acrylic resins, polyester resins, emulsion acrylic resins, and various ultraviolet curable resins. Specifically, the silicon-modified acrylic resin is a resin modified with an intermediate composed of siloxane such as methylpolysiloxane, ethylpolysiloxane, dimethylpolysiloxane, diethylpolysiloxane, and the like. Uses siloxane to give releasability, heat resistance, etc. In addition, Si-OH and Si-OMe are used as reactive groups, and acrylic resins that react with these reactive groups are blended, cooked and modified. And as an acrylic resin, acrylic acid ester, methacrylic acid ester, etc. can be used.

  Further, the wrap film holding portion P of the wrap film storage carton A of the present invention is provided with a plurality of convex portions T. The position where the convex portion T is provided is provided in a part or the whole of the wrap film holding portion P, but is preferably provided at a position where the wrap film F is pressed with a finger. As shown in FIG. 3, the shape of the convex portion T is preferably a circular mountain shape, and the upper surface is preferably a flat surface. Moreover, it is preferable to make the magnitude | size of the circular diameter of the base part of the convex part T into the range of 2-7 mm, and when it is less than 2 mm, adhesiveness falls extremely and the wrap film F is a wrap film holding | maintenance part. It becomes easy to peel off from P, and when it exceeds 7 mm, it adheres too much and becomes difficult to peel. Moreover, it is preferable to make the maximum height of the convex part T into the range of 0.1-1.0 mm, and when it is less than 0.1, the wrap film F adheres too much to the wrap film holding part P and peels. When the thickness exceeds 1.0 mm, the paperboard that is the material is cracked or the workability is deteriorated. Furthermore, the space | interval of adjacent convex part T is the range of 1-10 mm, Preferably it is the range of 2-5 mm, and can provide in a straight line form, a zigzag form, etc. When the interval between adjacent convex portions T is less than 1 mm, processing becomes difficult and the effect of facilitating peeling is reduced. On the other hand, when the interval exceeds 10 mm, the distance between the convex portions T and T is small. The part is also easily adhered, and the effect of facilitating peeling is lost. Further, the shape of the base portion of the convex portion T is preferably a circle from the viewpoint of easy processing, but other than the circle, an ellipse, an oval, a substantially polygon, or the like can be used.

  Next, in the case of such a wrap film storage carton A, the blank 10 is assembled as follows. First, the blank 10 is bent along the folding lines a, b, c, d, e, and f, the back surface of the folded piece 17 is attached to the back surface of the front plate 11, and then the second side pieces 20, 20 are attached. The first side piece 18, 18 ′ is sandwiched between the front surface of ′ and the back surface of the side plate 19, 19 ′, and the contact surfaces are adhered to each other, thereby forming a carton storage portion. Moreover, a cover part is formed by sticking the surface of the side cover pieces 22 and 22 ', and the back surface of the side cover plates 21 and 21'.

  In the wrap film storage carton A thus assembled, a roll-shaped wrap film or the like is stored in the recess of the storage portion. Then, the surface of the front plate 11 and the back surface of the opening piece 16 of the lid piece 15 are adhered by an adhesive applied in a band shape so as to overlap the half-cut portion 24 of the front plate 11, thereby sealing the carton. . In that case, only the inside of the half-cut portion 24 from which the overprint varnish is removed is bonded to the inside of the cut 23 of the opening piece 16.

  At the time of use, as shown in FIG. 6, when the opening piece 16 is pinched by the grip portion 25 on the proximal end side of the semicircular cut 23 and the opening piece 16 is separated from the location of the cut line L, The paper on the inner surface of a certain half-cut portion 24 is delaminated to open the carton, and the cutting blade H is exposed from the opened portion. At the same time, the roll-shaped wrap film F stored in the carton is also exposed, so that the wrap film F can be fed out by a necessary amount and cut by the cutting blade H. And the wrap film F after having extended | paid_out is closely_contact | adhered temporarily to the wrap film holding | maintenance part P, and it is prevented that it is wound in. When the wrap film F is pulled out again, the wrap film F is first peeled off from the wrap film holding portion P and then pulled out. At this time, since the wrap film holding portion P is provided with a plurality of convex portions T, the wrap film F is easily wrapped. The film F can be peeled off from the wrap film holding part P.

  FIG. 4 is a perspective view showing a second embodiment of the wrap film storage carton of the present invention. The wrap film storage carton B is different from the wrap film storage carton A of FIG. 1 in that the saw blade-shaped film cutting blade H is V-shaped as shown in FIG. Accordingly, the lid cover piece 15 is provided with a V-shaped cut line L having the same shape as the cutting blade H, and when the opening piece 16 is peeled off and removed, the cutting edge of the V-shaped cutting blade H slightly protrudes. Therefore, the cutting blade H is attached to the lid cover piece 15 at a position on the back surface of the lid cover piece 15 that hangs on the cut line L. And in the case of the cutting | disconnection of the wrap film F, the wrap film F is cut | disconnected from the center part of the wrap film F toward both sides, pressing down the wrap film F in the position near the V-shaped front-end | tip part of the lid piece 15. Therefore, as shown in FIG. 4, the wrap film holding part P can be provided at a position slightly above the center of the front surface of the front plate 11 of the wrap film storage carton B, so that the wrap film F is easily adhered. This is preferable.

  Since the wrap film storage carton B shown in FIG. 4 shows the state after the wrap film storage carton is opened, the wrap film storage carton B is ahead of the cut line L provided on the lid cover piece 15 in the same manner as the wrap film storage carton A. The portion is also an opening piece 16, which is peeled off and removed at the time of opening and is not displayed.

  FIG. 5 is a perspective view showing a third embodiment of the wrap film storage carton of the present invention. In this wrap film storage carton C, when the wrap film storage carton C is assembled, the film cutting blade H is slightly forward of the saw blade-shaped cutting blade H from the bottom plate 12 of the wrap film storage carton C, that is, It is attached to the surface of the bottom plate 12 so as to protrude toward the front plate 11 side. And the wrap film holding | maintenance part P is provided in the position where the wrap film F is hold | suppressed with the lid piece 15 and the film cutting blade H on the surface of the front board 11 of the wrap film accommodation carton C, as shown in FIG.
