Description

  The present invention relates to a backing film with a shrink film for fixing and packaging a string-like product, and displaying and selling it at a store.

  As a packaging form in which the product to be packaged is stored so that it can be seen together with the mount on which the display and design are printed, the packaged product is stored in a thermoformed plastic sheet and covered with the mount. There is a skin pack in which an article to be packaged is placed on top and directly wrapped with a heated film from above.

  In addition, the object to be packaged is applied to a card made of paper, synthetic resin, or metal plate, which is covered with a heat-shrinkable film (shrink film) of a cylindrical synthetic resin, and the film is heated to heat. There is card wrapping that is shrunk and applied tightly and integrally throughout.

  The mount with a shrink film proposed as one form of card packaging simply requires attaching a tubular shrink film to the mount in advance and inserting the product into the shrink film to cause heat shrinkage. However, in the mount with shrink film, it was necessary to manually open the shrink film and insert the product, and it took time and effort to open the collapsed shrink film.

  The mount with shrink film described in Patent Document 1 is divided into a front panel and a rear panel in order to save the trouble of opening the cylindrical shrink film, and the shrink film is arranged between the front panel and the shrink film. And partially adhered to the rear panel.

  The mount with shrink film described in Patent Document 1 is convenient for opening the shrink film, but unsuitable for inserting a product with no waist, such as a string-like product. Also, the package could not be displayed upright.

  The problem to be solved by the present invention is to propose a backing film with a shrink film that can efficiently store a string-like product, is excellent in appearance, and can also be displayed upright.

  As means for solving the above-mentioned problems, the invention described in claim 1 is composed of a mount, a cylindrical shrink film fixed to the mount, and a core for winding a string-like product. The shrink film-attached mount, wherein the winding core has a triangular tube shape, and has two bottom surfaces that form a mountain shape and a bottom surface that contacts the mount, and a ridge line where the bottom surface and the slope intersect each other from the bottom surface or the slope surface. A mount with shrink film, characterized by having a plurality of arc-shaped protrusions extending.

  The mount with shrink film according to the present invention has a triangular cylindrical core, and a plurality of arc-shaped protrusions extending from the bottom surface or the inclined surface are provided on the ridge line where the bottom surface and the inclined surface of the triangular tube intersect. When a string-like product is wound, it can be wound neatly without slipping, and since the protrusion is arcuate, it is not torn when the shrink film shrinks.

  The invention according to claim 2 is characterized in that a plurality of arc-shaped cut lines provided along mountain ruled lines in which the arc-shaped protrusions of the core are to be ridge lines where the bottom surface and the inclined surface cross each other are The mount with shrink film according to claim 1, wherein the mount is formed so as to protrude from the ridge line by folding the ruled line.

  The invention according to claim 3 is the mount with shrink film according to claim 1 or 2, wherein the triangular cylindrical core has a trapezoidal cross section at the center.

  The mount with a shrink film according to the present invention can be stored with a good appearance by winding a string-like product around a triangular cylindrical core. In addition, the triangular cylindrical core has two slopes that form a mountain shape with the bottom surface in contact with the mount, and a plurality of arc-shaped protrusions extending from the bottom surface or slopes on the ridgeline where the bottom surface and the slope intersect. So, when winding a string-like product, it can be wound neatly without slipping.

  Further, since the protrusion is provided on the ridge line where the bottom surface of the winding core and the inclined surface intersect, when the shrink wrapping is performed, the protrusion easily adheres to the mount and can be packaged with good appearance. Further, since the projection is arcuate, it is difficult for the film to be caught and torn.

  As in the invention described in claim 2, a plurality of arc-shaped cut lines provided on the arc-shaped protrusions of the core along the mountain-fold ruled lines to be ridge lines where the bottom surface and the inclined surface cross each other are the mountain-fold ruled lines. When the sheet is formed so as to protrude from the ridgeline, the target core can be prepared by a simple operation of folding a planar cardboard along the mountain fold ruled line.

  Moreover, when the cross section of the central part of the triangular cylindrical core is trapezoidal as in the invention described in claim 3, the string-like product is in a horizontal state in the central part of the core. As a result, the display effect will increase. Also, when shrink-wrapped, the tightening force is not concentrated and the product is less damaged than in the case of a triangular cylinder. Furthermore, since the upper and lower ends are higher than the center of the core, there is an effect of protecting the product.

  Hereinafter, the mount with shrink film according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a package 20 using a mount 1 with a shrink film according to the present invention. FIG. 2 is a schematic cross-sectional view showing the A-A ′ cross section of FIG. 1.

  A mount 1 with a shrink film according to the present invention includes a mount 2, a tubular shrink film 3 fixed to the mount, and a core 4 for winding a string-like product 13. It is.

  The winding core 4 has a triangular tube shape, and has two slopes 6 forming a mountain shape with the bottom surface 5 in contact with the mount 2, and extends from the bottom surface 5 or the slope 6 to the ridgeline 7 where the bottom surface 5 and the slope 6 intersect. A plurality of arcuate protrusions 9 are provided. In the example shown in FIG. 1, the plurality of arcuate protrusions 9 are extended from the bottom surface 5.

  FIG. 3 is a schematic plan view showing a state in which the mount 2 and the shrink film 3 of the mount with the shrink film shown in FIG. 1 are fixed. In this example, the tubular shrink film 3 is fixed to the mount 2 with an adhesive 10.

  When the triangular cylindrical core 4 around which the string-like product 13 is wound in advance is inserted into the cylindrical shrink film 3 and the whole is passed through the shrink tunnel and heated, the shrink film contracts and the string The product and the core are firmly fixed to the mount.

  FIG. 4 is a perspective view showing an embodiment of a triangular cylindrical core 4 which is a constituent element of the mount 1 for shrink film according to the present invention. FIG. 5 is a schematic plan view showing a blank 4B of the core 4 shown in FIG.

  In this example, the arc-shaped protrusion 9 of the winding core 4 has a plurality of arc-shaped cut lines 8 provided along the mountain crease line 12 to be the ridge line 7 where the bottom surface 5 and the inclined surface 6 cross each other. Is formed so as to protrude from the ridge line 7 by being folded.

  By doing in this way, the arc-shaped protrusion 9 extended from the bottom face 5 is automatically formed only by folding the blank 4B of the core along the three mountain fold ruled lines 12.

  Since there are a plurality of arc-shaped protrusions 9 on the ridge line 7, the winding does not shift when the string-like product 13 is wound around the core 4. Moreover, since the tip of the projection is arc-shaped and smooth, the shrink film 3 is not torn when the shrink film 3 is contracted.

  The packaging body 20 shown in FIG. 1 can be hooked on the hook of the exhibition stand using the suspension holes 11 provided in the mount 2, or as shown in FIG. It is also possible to stand up and display by aligning the end faces and packaging.

  Further, the triangular cylindrical core 4 can be used without using an adhesive or the like so that it naturally expands when the string-like product 13 is removed. In that case, only the outer surface of the core is used. In addition, various information can be described on the inner surface, leading to an increase in display area.

  Furthermore, since the inside of the triangular cylindrical core 4 is hollow, accessories and instruction manuals can be inserted here. In this case, a lid may be provided on the cylindrical core.

  FIG. 6 is a perspective view showing another embodiment of the triangular cylindrical core 4. In this example, the plate that forms the slope 6 and the plate that forms the bottom surface 5 are made of different members, and a plurality of arc-shaped protrusions 9 are formed on the left and right ends of the bottom plate. The plate that forms the inclined surface and the plate that forms the bottom surface may be bonded with an adhesive or the like, or may be integrated by inserting an insertion protrusion into the cut.

  FIG. 7 is a perspective view showing an embodiment of a triangular cylindrical core in the invention of claim 3. In this example, the upper part and the lower part of the core 4 are triangular cylinders, but the central part has a trapezoidal cross section.

  This trapezoidal shape is caused by six mountain crease lines 12 and two valley crease lines 14 provided on two slopes 6.

  In this way, when the cross section of the central part of the triangular cylindrical core is trapezoidal, the string-like product is observed in a horizontal state in the central part of the core, so the display effect is enhanced. . Also, when shrink-wrapped, the tightening force is not concentrated and the product is less damaged than in the case of a triangular cylinder. Furthermore, since the upper and lower ends are higher than the center of the core, there is an effect of protecting the product.

  In addition, since the upper surface of the central part of the core is flat, there is an advantage that when the display is performed on this part, the display is easy to read.

  As the mount 2 used for the mount with a shrink film according to the present invention, a plate-like one such as paper, a plastic sheet, a metal plate, or the like can be used. The paper is not particularly limited as long as it is thick paper and is stiff. Also, aluminum vapor-deposited paper having an aluminum vapor-deposited layer on the surface can be used.

  The shrink film 3 may be a film that shrinks by heat, and a film whose shrinkage amount in the direction of narrowing the tube is larger than the shrinkage amount in the direction of shortening the tube is a product when shrinking when shrink wrapping. Is difficult to remove from the shrink film and is suitable for this application.

  As a material of the shrink film 3, polystyrene resin, polyvinyl chloride resin, polypropylene resin, polyethylene resin, polyester resin, or the like is used. Tubes that have been cooled by stretching these resin films in the thickness direction will shrink and hold the product firmly when inserted into a packaged product and heated to around 100 ° C in a shrink tunnel. To do.

  As a method of fixing the shrink film 3 to the mount 2, an adhesive tape or the like may be used, but an adhesive 10 is generally used. As the adhesive 10, a hot-melt adhesive that can be applied in a heated state and immediately solidified to exhibit an adhesive force by cooling is preferably used.

  Among hot-melt adhesives, reactive hot-melt adhesives are cured by reacting with moisture in the air after solidification, and after curing, they will not melt even when reheated. It can be most preferably used for applications such as heating in a tunnel.
