Description

  The present invention belongs to the technical field of cartons for storing wrap films used for food packaging in general households and the like, and in particular, relates to a carton for wrap films having a function of preventing unwinding of wrap films fed out by hand. Is.

  Conventionally, as a representative of this kind of carton for wrap film, a smooth surface is provided on a portion of the front side plate of the carton body that is covered with a lid piece, and is temporarily adhered to the smooth surface by the self-adhesiveness of the wrap film. Thus, many are used which prevent the wrap film from being unwound after being cut out. Such smooth surfaces include plastic films and other smooth surfaces, including those in which the irregularities of container materials such as paper are completely smoothed by repeatedly applying solutions and emulsions such as polystyrene and vinyl chloride. There are known those in which a sheet is attached (see Patent Document 1), and those in which a smooth coating layer is provided with a crosslinkable curing varnish (see Patent Document 2).

  In the conventional carton that prevents the wrap film from rewinding on the smooth surface as described above, the self-adhesiveness of the wrap film is exhibited while the smooth surface is clean, and the wrap film is prevented from unwinding after cutting. However, when hand dirt or the like adheres during use, the adhesiveness of the smooth surface gradually deteriorates and the wrap film is peeled off, which makes it impossible to prevent rewinding. In addition, the wrap film was peeled off from the smooth surface by vibration applied to the carton.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a wrap film carton that can reliably rewind a film after cutting.

  In order to achieve the above object, the present invention provides a carton body having a long box shape with an opening at the top, and a rear side edge of the upper opening in the carton body that is undulated and connected to the front plate of the carton body. In a carton for a wrap film comprising a lid body having overlapping lid pieces and a cutting blade attached along the tip back side of the lid piece, at a predetermined position facing the front side of the front plate and the back side of the lid piece, Each of the sheet pieces is pasted in a combination in which one is an adsorbing sheet piece made of a magnetic sheet and the other is an adsorbed sheet piece that can stick to the adsorbing sheet piece.

  And it is preferable to apply | coat a stopper varnish on the surface of the sheet piece stuck on the front side of a front side board in the carton for lap films of the said structure.

  The carton for a wrap film of the present invention has an adsorbed sheet in which one side is an adsorbing sheet piece made of a magnetic sheet and the other is attached to the adsorbing sheet piece at a predetermined position on the front side of the front side plate and the back side of the lid piece. Since the sheet pieces are pasted together in a combination of pieces, when the wrap film is fed out and the lid is closed, the wrap film is sandwiched between the adsorbed sheet piece and the adsorbed sheet piece, and the wrap after cutting Rewinding of the film can be reliably prevented.

  And if a stopper varnish is apply | coated to the surface of the sheet piece stuck on the front side of a front side board, a film can be fixed more reliably.

It is a perspective view which shows an example of the carton for wrap films which concerns on this invention. It is an expanded view of the blank which assembles the carton for wrap films of FIG. It is a perspective view which shows the opening method of the carton for wrap films of FIG. It is a perspective view shown in the state which opened the carton for wrap films of FIG. It is explanatory drawing which shows the center cross section of the longitudinal direction in the carton for wrapping films of an open state.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an example of a carton for a wrap film according to the present invention, and this carton for a wrap film is formed by assembling a blank whose development is shown in FIG.

  The blank of FIG. 2 is produced by punching a paperboard, and as shown in the drawing, the front side plate 11, the bottom plate 12, the rear side plate 13 and the cover plate 14 are continuously connected via a folding line. A folding piece 15 is connected to the longitudinal end edge of the side plate 11 via a folding line, and a lid cover piece 16 is connected to the longitudinal end edge of the lid plate 14 via a folding line. An opening piece 17 is connected to the piece 16 via a cut line α. Since the unsealing piece 17 is separated from the lid cover piece 16 with the cutting line α as a boundary, the cutting line α is formed in a form that is easy to cut such as a perforation or a lead rule. The opening piece 17 is formed with a total of six semicircular cuts β in the same direction at equal intervals along the longitudinal direction. And the cutting blade C is attached to the back surface of the lid piece 16 along the cutting line α in a state where the cutting edge protrudes toward the opening piece 17 side. As the cutting blade C, in consideration of environmental problems, a hard paper board is punched and saw blades are formed on both edges.

  At both ends (left and right in the figure) of the front side plate 11, the bottom plate 12, the rear side plate 13, the lid plate 14 and the lid cover piece 16, an adhesive piece 18, a side plate 19, a folded piece 20, and a lid side plate are respectively connected via folding lines. 21 and the adhesive piece 22 are provided continuously. Here, the length of the side plate 19 is substantially the same as the width of the front side plate 11 and the rear side plate 13, the length of the bent piece 20 is shorter than the side plate 19, and the length of the adhesive piece 18 is shorter than that. Yes. The length of the lid body side plate 21 is about half of the length of the side plate 19, and the length of the adhesive piece 22 is shorter than the width of the lid plate 14.

  While assembling this blank, the roll of wrap film is accommodated, but, as shown in FIG. 2, with respect to the blank before assembling, at a predetermined position facing the front side of the front plate 11 and the back side of the lid cover piece 16, Each of the sheet pieces is bonded with a double-sided tape in such a combination that one is an adsorbing sheet piece M made of a magnetic sheet and the other is an adsorbed sheet piece S that can stick to the adsorbing sheet piece M. Here, as shown in the drawing, an adsorbing sheet piece M is attached to the front side of the front plate 11, and an adsorbed sheet piece S is attached to the back side of the lid cover piece 16.

  A magnet sheet is obtained by magnetizing a sheet of ferrite (iron oxide) mixed with resin (binder), and isotropic magnet sheet and anisotropic magnet with stronger magnetic force than that. The adsorbing sheet piece M used in the present invention does not require a large adsorbing force, but is an isotropic magnet sheet and is a normal magnet with single-sided multipolar magnetization (100 to 500 gauss). A sheet may be used. Further, as the adsorbed sheet piece S, any material can be used as long as it adheres to the adsorbing sheet piece M, but here, a non-magnetized ferrite sheet is used.

  The procedure for assembling the blank of FIG. 2 is as follows. First, the folded piece 15 is bent and the back side is attached to the back side of the front plate 11. Next, the surface of the front plate 11 and the back surface of the opening piece 17 are pasted together with an adhesive applied in a strip shape so as to overlap the semicircular cut β of the opening piece 17 and sack-attached. At this time, the adhesive portion of the front side plate 11, that is, the circular adhesive portion corresponding to the semicircular cut β of the unsealed piece 17 has the overprint varnish (stopper varnish) removed during printing, and only this circular adhesive portion. Is bonded to the inside of the semicircular cut β of the opening piece 17.

  And after raising the blank that has been sack pasted into a square tube shape, with one end closed, the roll-shaped wrap film is introduced from the other open end, and then the open end By closing the part, a wrap film carton as a product shown in FIG. 1 is created. Here, either end is closed by the following procedure. That is, the folded piece 20, the adhesive piece 18 and the side plate 19 are sequentially bent, the adhesive piece 18 is sandwiched between the front surface of the folded piece 20 and the back surface of the side plate 19, and the respective contact surfaces are bonded to each other so that the carton body side Next, the adhesive piece 22 and the lid side plate 21 are sequentially bent, and the surface of the adhesive piece 22 and the back surface of the lid side plate 21 are bonded together to close the lid side.

  When using the wrap film carton shown in FIG. 1, the end of the opening piece 17 is picked and pulled in the direction of the arrow shown in FIG. Then, the paper is delaminated inside the semicircular cut β that is the bonding portion, the opening piece 17 is cut off from the cut line α, and the cutting blade C is exposed. After opening in this way, when the lid is lifted and opened, the roll-shaped wrap film F housed in the carton is exposed as shown in FIG. Then, it becomes possible to cut with the cutting blade C.

  When taking out the wrap film F, hold the vicinity of the center of the carton with your hand, lift the lid diagonally with that hand, pick the end of the wrap film F with the other hand, and pull out the required amount. (See FIG. 4 and FIG. 5) Cover the lid piece 16 directly on the front plate 11, and cut with the cutting blade C with the wrap film F sandwiched between the front plate 11 and the lid piece 16. When this cutting operation is performed, the remaining wrap film F is in a state in which the end portion is sandwiched between the suction sheet piece M and the suctioned sheet piece S, so that even after cutting, the wrap film F cannot be rewound into the carton body. Absent.

  Further, since the lid cover piece 16 is fitted to the front plate 11 by the magnetic force of the suction sheet piece M and the suctioned sheet piece S, the cutting of the wrap film F with the cover open halfway is reduced. We can expect reduction of mistakes. In addition, by sticking the suction sheet piece M and the suctioned sheet piece S, there is also an advantage that the strength of the finger pressing portion is improved, which is effective in the case of a carton storing a long roll.

  As mentioned above, although embodiment of this invention was described in detail, the carton for wrap films by this invention is not limited to an above-described embodiment at all, In the range which does not deviate from the meaning of this invention, various changes are possible. Is possible.

  For example, many conventional wrap film cartons have a stopper varnish applied to the front plate surface to prevent film rewinding. In the present invention, the same stopper varnish is applied to the front plate 11 as well. Alternatively, the film may be securely fixed by applying a stopper varnish on the surface of the suction sheet piece M or the suction sheet piece S attached to the front plate 11.

  Also, in the case of a long wrap film carton, the combination of the adsorbing sheet piece M and the adsorbing sheet piece S is moved from the center to the left and right when considering the use of both right-handed and left-handed people. You may make it provide in two places.

  In the above example, the end edge of the lid piece is straight, but the carton for wrap film of the present invention may be V-shaped with the center protruding.
