Description

The present invention relates to a mount with a shrink film, and more particularly to a mount with a shrink film that can be stably held even when an object to be packaged is heavy.

2. Description of the Related Art Conventionally, a storage container for packaging a product to be packaged so as to be visible from the outside has been used. For example, a blister package, a skin pack, a card package, or the like, in which an object to be packaged which is directly wrapped with a transparent packaging material is fixed to a mount on which a product label or design is printed is used. Blister packaging is a method in which the article to be packaged is housed in a thermoformed plastic sheet, and is covered with a backing sheet for packaging. The skin pack is a method in which an object to be packaged is placed on a mount and directly packaged with a film heated from above. In card packaging, the backing made of paper, synthetic resin, or a metal plate is coated with a heat-shrinkable film of synthetic resin, and the film is overheated and heat-shrinked so that the whole is tightly and integrally applied. It is a method of packaging.

As an example of the above packaging, a heat-shrinkable tube (cylindrical shrink film) is adhered with an adhesive applied to the mount to form a mount with a shrink film, and the shrink film is heat-shrinked while the packaged item is stored. A package in which an article to be packaged is attached to a mount is known (Patent Documents 1 and 2).
Further, as a mount with a shrink film, some forms have been proposed in which both a hanging display and a self-supporting display on a product shelf or the like are possible (Patent Document 3).

JP-A-49-3796 JP, 2013-82460, A JP 2012-20762 A

In the packages disclosed in Patent Documents 1 to 3, since the object to be packaged is attached to the front surface of the mount, the package is attached to the front of the mount at a distant position such as when the weight of the packaged object is large or the size is large. The center of gravity of the object to be packaged may be positioned and the mount may bend forward during hanging display, resulting in poor appearance.

In the packaging disclosed in Patent Document 3, since the opening of the shrink film is located in the vertical direction of the article to be packaged, when the article is hung or displayed on a shelf at the store, the bottom or top of the article (the article to be packaged) is placed. Dust may adhere to the surface.

In addition, there is a demand that the surface to be viewed of the packaged object is placed on the front surface and attached to the mount. For example, in a cylindrical container in which the characteristics of the product are written on the upper surface of the cap, it is desired to arrange and package the container so that the upper surface of the cap is the front surface. In addition, for example, an adhesive tape or the like for taping the body has a cylindrical shape in which an adhesive tape having elasticity and cushioning properties is wound around a winding core. In such an adhesive tape, a sheet on which a product name or the like is written may be provided on the surface in the thickness direction of the adhesive tape, and in order to improve the visibility, it is desired to arrange this sheet on the front surface for packaging. In the packaging disclosed in Patent Document 1 and Patent Document 2, the shrink film is heat-shrinked by placing the object to be packaged in the cylindrical space of the shrink film in a state where the shrink film is cylindrically attached to the mount. Therefore, in order to arrange the sheet of the adhesive tape on the front surface, it is necessary to arrange it in the direction in which the winding core of the adhesive tape is orthogonal to the tubular axis of the shrink film. At this time, when the object to be packaged is soft like an adhesive tape having elasticity and cushioning property, the shrink film may distort the outer shape of the object to be packaged, which may impair the appearance.

Further, in the case of packaging a product having a shape in which the axial and circumferential dimensions are significantly different, such as a tubular or rectangular parallelepiped product that is long in the axial direction, when the major axis is orthogonal to the mount, The circumferential dimension of the shrink film and the axial dimension of the shrink film are significantly different. Therefore, the adhesive portion between the shrink film and the mount is short, and it is difficult to stably support the packaged object when the packaged object is heavy.

The present invention has been made in view of the above circumstances, and is stable while ensuring visibility even when the object to be packaged has a large weight and the aspect ratio of the dimensions is large and the object to be packaged is projected to the front. The purpose of the present invention is to provide a mount with a shrink film that can be packaged.

The mount with a shrink film according to the present invention is a tubular shrink film that wraps an object to be packaged, a first panel part, a second panel part in which an opening is formed, the first panel part and the second panel. And a mounting portion for supporting an object to be packaged wrapped in the shrink film, and a mounting sheet to which the shrink film is adhered, In a state in which the one panel portion and the second panel portion are folded with respect to the mounting portion, at least a part of the first panel portion and the second panel portion are joined to each other, and the front of the folded mount is The shrink film is opened in the depth direction of the writing portion, and the shrink film is attached to the writing portion via the adhesive portion .

In the mount with a shrink film according to the present invention, the adhesive portion is provided to extend in a direction intersecting a folding line between the placing portion and the first panel portion or the second panel portion, and the shrink film is Alternatively, the adhesive portion may be attached in a tubular shape in the extending direction.

In the mount with a shrink film according to the present invention, the lower end of the opening may be formed at a position including a fold line between the placing part and the second panel part.

In the mount with a shrink film according to the present invention, the edge portion of the mounting portion is formed to extend into the opening, the second panel portion is bent with respect to the mounting portion, the edge. The end portion may be configured to project forward of the folding line between the placing portion and the second panel portion.

The mount with a shrink film according to the present invention may have an opening formed in the first panel portion.

ADVANTAGE OF THE INVENTION According to this invention, even if it is the case that the to-be-packaged object with large weight and the aspect ratio with a large dimension is projected to the front, and packaging is carried out, the mount with a shrink film which can be accommodated stably, ensuring visibility. Can be provided.

It is a perspective view showing a use mode of a mount with a shrink film concerning one embodiment of the present invention. It is a top view of the mount with a shrink film concerning one embodiment of the present invention. It is a front view showing a use mode of a mount with a shrink film concerning one embodiment of the present invention. It is a top view of the modification of the mount with a shrink film. It is a side view which shows the usage condition of the modification of the mount with a shrink film. It is a front view of FIG.

Hereinafter, an embodiment of a mount with a shrink film according to the present invention will be described with reference to FIGS. 1 and 2.
FIG. 1 is a perspective view showing a usage mode of a mount 1 with a shrink film according to the present embodiment. FIG. 2 is a plan view showing the unfolded mount 1 with shrink film.

The mount 1 with a shrink film according to the present embodiment includes a shrink film 2 and one mount 3 as shown in FIGS. 1 and 2. The shrink film is a film having heat-shrinkability, and when it is heat-shrinked, it wraps a part or all of the packaged object placed inside.

In the shrink film 2, two opposing side edges 21 and 22 of a rectangular film are overlapped and rolled into a tubular shape, and the overlapped side edges 21 and 22 are adhered to each other to form a seal portion 23. ing.

The shrink film 2 may be a film that shrinks by heating. As a material of the shrink film 2, for example, polystyrene, polyvinyl chloride, polypropylene, polyethylene, or polyester resin is preferably used. Polylactic acid, which is a sustainable material derived from agricultural products, can be used as the polyester-based resin, and can be preferably used as an environment-friendly packaging.

As the shrink film 2, either a uniaxially stretched film or a biaxially stretched film can be used, but the uniaxially stretched film is preferred from the viewpoint of controlling the shape change during heat shrinkage. For example, when the shrink film 2 is arranged so that the contraction in the circumferential direction is larger than the contraction in the axial direction when the ends are bonded to each other to form a tubular shape, the shrink film 2 shrinks when shrink-wrapped. Since P does not come off from the shrink film 2, it is suitable for this application.

Moreover, since the shrink film 2 generates a larger tension when it shrinks as the shrinkage ratio upon heating (the shrinkage ratio of the length in the predetermined direction when shrinking) is higher, for example, a shrink film having a shrinkage ratio of 40% or more is preferable. .. However, since the tension changes depending on the area of the shrink film 2 and the like, the shrinkage rate and the area of the shrink film 4 are appropriately set depending on the shape of the article P to be packaged, the rigidity of the mount 3 on the side to be adhered, and the like. Good to be. The shrink film is set longer than the size of the article P to be packaged. Further, the shrinkage starting temperature of the shrink film 2 is preferably set to 60° C. or higher so that the shrink film 2 does not start shrinking in the distribution stage before use of the shrink film-equipped mount 1.

The mount 3 includes a first panel unit 4, a second panel unit 5, and a mounting unit 6. As shown in FIG. 2, the mount 3 includes a substantially rectangular sheet on which the first panel portion 4, the mounting portion 6, and the second panel portion 5 are in the direction of the arrow Y shown in FIG. They are provided in order in the longitudinal direction), and folding lines 81 and 82 are formed at the boundaries of the respective regions. The arrow Y direction shown in FIG. 2 is the vertical direction of the first panel portion 4 and the second panel portion 5 and the depth direction of the mounting portion 6 when the mount 1 with shrink film is made into a three-dimensional shape.

As the mount 3 used for the shrink film mount 1, a plate-shaped material such as paper, a plastic sheet, or a metal plate can be used. The paper is not particularly limited as long as it is thick and has rigidity. Further, aluminum vapor deposition paper having an aluminum vapor deposition layer on the surface can also be used. In addition to the product name and description of the article P to be packaged, a pattern or the like that enhances the design may be appropriately printed on the mount 3.

The second panel portion 5 is formed in a substantially rectangular shape, and has an opening 52 formed by cutting out the central portion in the arrow X direction shown in FIG. 2 and the vicinity of a folding line 82 with the mounting portion 6. A through hole 9 for suspending and displaying the mount 1 with the shrink film is formed in a substantially central portion of the upper end 51 of the second panel portion 5 when the mount 1 with the shrink film is three-dimensionally assembled. The opening 52 is appropriately set according to the shape and size of the article P to be packaged. In the present embodiment, the opening portion 52 is formed to have two linear portions 521 extending in parallel to the arrow Y direction and an arch portion 522 that is convex toward the upper end portion 51 of the second panel portion 5. There is.

The mounting portion 6 is located between the first panel portion 4 and the second panel portion 5. The dimension of the mounting portion 6 in the arrow Y direction is shorter than the dimension of the first panel portion 4 and the second panel portion 5 in the arrow Y direction. At the center of the mounting portion 6 in the direction of the arrow X shown in FIG. 2, an extending portion 62 is formed so that the edge portion 61 of the mounting portion 6 projects into the opening 52 of the second panel portion 5. ing. The fold lines 82 are formed on both sides of the extending portion 62 in the arrow X direction, avoiding the extending portion 62.

The first panel portion 4 is formed in a substantially rectangular shape, and a through hole 9 for suspending and displaying the mount 1 with the shrink film is provided at a substantially central portion of the upper end portion 41 when the mount 1 with the shrink film is three-dimensionally assembled. Are formed. In the arrow Y direction, the dimension of the first panel portion 4 is slightly shorter than that of the second panel portion 5.

An adhesive portion 35 is provided at the center of the mounting portion 6 in the direction of the arrow X shown in FIG. 2, and the shrink film 2 is attached thereto. The adhesive portion 35 is provided on the mounting portion 6 so as to have a rectangular shape extending in a direction orthogonal to the folding line 81. As the adhesive used for the adhesive portion 35, a pressure-sensitive adhesive may be used as in Patent Document 1. Alternatively, a hot melt adhesive may be used. A reactive hot melt adhesive is preferable especially when exposed to a high temperature in a sunny store or the like. Conventional hot melt adhesives are those that contain a thermoplastic resin as a component, solid hot melt adhesives are heated, melted and applied, and then solidified and adhered by cooling, and there is a limit in terms of heat resistance. ..

Reactive hot-melt adhesives are solid at first, and using them by heating and melting are the same as conventional hot-melt adhesives for plastic resins, but after application and cooling, the reaction proceeds and cures. Thus, adhesiveness with high physical properties such as heat resistance can be obtained. Reactive hot-melt adhesives containing urethane resin as the main component are solidified with the urethane prepolymer produced by heating and melting leaving the terminal isocyanate groups when cooled, and even in the air after cooling. Moisture contained in the adherend reacts with the terminal isocyanate group to promote high molecular weight, and adhesiveness with higher heat resistance can be obtained. A reactive hot melt adhesive containing a urethane resin as a main component does not require a treatment for promoting curing after application, and thus can be preferably used.

The seal portion 23 is attached to the mounting portion 6 of the mount 3 by the adhesive portion 35. The seal portion 23 is preferably on the surface on the adhesive portion 35 side, that is, on the surface on the side that contacts the mounting portion 6 of the mount 3. It is more preferable that the shrink film 2, which is formed by wrapping and shrinking the object to be packaged, is arranged in the vicinity of the adhesive portion 34 so as to be as inconspicuous as possible when the shrink film 2 stands up from the mounting portion 6.
In the cylindrical shrink film 2, one opening is arranged along the fold line 81, the other opening is arranged so as to project further forward than the edge portion 61, and a fold line is provided in the arrow Y direction so as to crush the cylinder. Has been.

Next, with reference to FIG. 1 and FIG. 3, a state where the mount 1 with shrink film is three-dimensionally assembled will be described. FIG. 3 is a front view showing a usage mode of the mount 1 with shrink film. As shown in FIG. 1, the backing sheet 3 is folded along the two folding lines 81 and 82 to raise the first panel portion 4 and the second panel portion 5 into a three-dimensional shape, and the upper end portion 41 of the first panel portion 4 and the second The upper end portion 51 of the panel portion 5 is aligned and brought into contact. In this state, the first panel portion 4 and the second panel portion 5 are attached with an adhesive or the like. Since the dimension of the second panel portion 5 in the arrow Y direction is longer than that of the first panel portion 4, the second panel portion 5 bends toward the first panel portion 4 side to form a curved surface, as shown in FIG. .. Since the folding line 82 at the boundary between the second panel portion 5 and the placing portion 6 is formed so as to avoid the extension portion 62, the extension portion 62 is folded even when the second panel portion 5 is started up. It is not bent and is located on the same plane as the rest of the mounting portion 6.

With the backing sheet 3 in a three-dimensional shape, the article P to be packaged is inserted from the opening of the tubular shrink film 2 on the opening 52 side. In the present embodiment, an example of packaging a columnar object P to be packaged is shown.
The object to be packaged P is arranged with a gap of 3 mm or more between it and the folding line 81 of the first panel portion 4, and on the second panel portion 5 side, it is inside the end portion of the shrink film (first portion). It is arranged so that the end portion is located on the panel portion 4 side). That is, the shrink film 2 projects 3 mm or more from the end of the packaged object P on the first panel section 4 side in the state where the packaged object P is inserted, and on the second panel section 5 side. The front is projected longer than the front position.

By shrinking the shrink film 2 by heat shrinking the shrink film 2 by heating at around 180° C. or at about 55 to 60° C. in a state where the packaged object P is arranged in the tubular shrink film 2. 2 is brought into close contact with the article P to be packaged. At this time, the curing of the reactive hot melt adhesive is progressing, and therefore the adhesive strength of the adhesive portion 35 is not deteriorated by heat. Therefore, the shrink film 2 does not peel off from the mount 12, and the position where the shrink film 2 is attached to the mount 3 does not shift.

In the state where the packaged object P is packaged in the tubular shrink film 2, the packaged object P has a part of the upper surface P1 side protruding outward (forward) from the opening 52. A part of the upper surface P1 side of the article to be packaged P is supported by the extending portion 62. On the other hand, the lower surface (not shown) of the article to be packaged P is close to the first panel section 4.

In this way, when the article P to be packaged is wrapped in the three-dimensional mount 1 with shrink film, it can be hung and displayed at the store through the through hole 9 in a hook or the like provided on the product display stand at the store or the like. Further, the placing portion 6 serves as a bottom portion and can be placed directly on a product display stand for exhibition, and even a cylindrical object P can be exhibited while the upper surface P1 is arranged in front as shown in FIG. The package P does not roll in the circumferential direction.

In the mount 1 with the shrink film according to the present embodiment, the article to be packaged is stably supported on the mounting portion. Therefore, even a heavy packaged object or a long packaged object can be displayed without damaging the appearance by preventing the backing sheet from being bent or damaged. Therefore, even when an object to be packaged with a large weight or an object to be packaged with a large dimensional aspect ratio is projected on the front surface to be packaged, it is possible to stably package while ensuring visibility.

In the backing sheet with shrink film 1 according to the present embodiment, the lower end portion 53 of the opening 52 is formed at a position including the folding line 82 between the placing portion 6 and the second panel portion 5, so that the article to be packaged is In the state where P is supported by the mounting portion 6, the article P to be packaged can be visually recognized from the opening 52. Therefore, the article to be packaged P can be easily visually recognized from the outside of the packaging container.

The mount 1 with a shrink film according to the present embodiment has a mounting portion 6 at the bottom, the upper surface side is covered with the first panel portion 4 and the second panel portion 5, and the opening of the tubular shrink film 2 is formed. Opens in the depth direction of the mount 1 with shrink film. Therefore, the upper and lower surfaces of the article to be packaged are covered, dust is unlikely to adhere to the article when it is displayed, and the article can be displayed without impairing its appearance.

In the mount 1 with the shrink film according to the present embodiment, when the three-dimensional assembly, the edge portion 61 of the mounting portion 6 is configured to project to the front side from the fold line 82, and thus the packaged object P Can be supported by the extending portion 62 in a state of being projected from the front surface of the second panel portion 5. Therefore, the packaged object P can be stably supported even when the packaged object P projects from the opening 52.

Although one embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment, and various modifications may be made to each component without departing from the spirit of the present invention. , Or the configurations of the respective embodiments can be combined.

Modifications of the mount 1 with shrink film according to the above embodiment are shown in FIGS. 4 to 6. FIG. 4 is a plan view of a mount 10 with a shrink film according to a modified example. FIG. 5: is a side view which shows the state which mounted the mount 10 with a shrink film of a modification in three dimensions, and FIG. 6 is the same front view. The same components as those of the mount 1 with the shrink film in the above-described embodiment are designated by the same reference numerals, and duplicate description will be omitted.

In the above-described embodiment, the configuration in which the opening 52 is formed only in the second panel portion 5 has been illustrated, but in the present modification, the opening 42 is also formed in the first panel portion 4. As shown in FIG. 4, in the opening portion 42 of the first panel portion 4, the lower end portion 43 of the opening portion 42 has a folding line 81 between the mounting portion 6 and the first panel portion 4, similarly to the opening portion 52. Located in the vicinity.

In the above-described embodiment, the configuration in which the extension portion 62 is provided on the mounting portion 6 has been shown, but the extension portion 62 is not an essential configuration, and the extension portion 62 is provided as in the mount 10 with the shrink film of the modification. Alternatively, the edge 61 may be on the same line as the folding lines 81 and 82, that is, the lower ends 43 and 53 of the openings 42 and 52. In the mount 10 with the shrink film of the modified example, the adhesive portion 35 is provided along the arrow Y direction of the mounting portion 6 (longitudinal direction of the mount 3), and the end portion of the tubular shrink film 2 in the arrow Y direction is mounted. The edge portions 61 of the mounting portion 6 are arranged and bonded so as to project above the edge portions 61 (upper and lower sides shown in FIG. 4).

In the above-mentioned embodiment, although the upper end portions 41 and 51 of the first panel portion 4 and the second panel portion 5 are brought into contact with each other to be joined, the first panel portion 4 and the second panel portion 5 are connected. The structure for joining the is not limited to this. At least a part of the first panel portion and the second panel portion may be joined to each other. For example, in the mount 10 with the shrink film of the modified example, the flap 44 is provided in the upper end portion 410 of the first panel portion 40 substantially in the center in the arrow X direction, and the upper end portion 51 of the second panel portion 50 is substantially formed in the arrow X direction. A notch 54 is formed in the central portion and below the through hole 9. The dimension of the first panel portion 40 is shorter than that of the second panel portion 50 in the arrow Y direction. As shown in FIG. 6, the first panel section 40 and the second panel section 50 are bent at the folding lines 81 and 82 to stand up, the first panel section 40 and the second panel section 50 are opposed to each other, and the flap is provided. 44 is inserted into the notch 54, and the first panel section 40 and the second panel section 50 are engaged and joined. In addition, the flap may be formed on the second panel portion, and the notch may be formed on the first panel portion to engage the both.

As shown in FIG. 5, when the mount 10 with the shrink film of the modified example is formed into a three-dimensional shape, the first panel unit 40, the second panel unit 50, and the mounting unit 6 are substantially isosceles triangles in a side view. The article P having a shape and having a substantially columnar shape is inserted into the opening 42 of the first panel section 40 and the opening 52 of the second panel section 50, and is supported by the placing section 6. Even with such a configuration, as in the case of the backing sheet with shrink film 1 according to the above-described embodiment, even when a large object to be packaged or an object to be packaged with a large aspect ratio is packaged by projecting to the front. , It can be packaged stably while ensuring visibility.

Further, in the mount 10 with the shrink film of the modified example, since the opening 42 is also formed in the first panel portion 40, the article P to be packaged is substantially centered in the depth direction (arrow Y direction) of the mounting portion 6. Can be fixed with. Therefore, the center of gravity of the packaged object can be arranged at a position where it is more stable, even for a long packaged object or a packaged object having a large weight. Moreover, both the upper surface and the lower surface of the packaged object can be visually recognized. Therefore, when the product name or the like is displayed on the upper surface of the packaged object and the component display or the like is described on the bottom surface, the consumer can confirm both.

In addition to the above, in the above-described embodiment and modification, the configuration in which the adhesive portion 35 is provided on the placing portion 6 is shown, but if the packaged object is supported by the placing portion, the position at which the adhesive portion is provided is particularly Not limited. For example, although not shown, an adhesive portion is provided so as to extend in the up-down direction of the first panel portion, and a tubular shrink film is attached so that the tube extends in the up-down direction of the first panel portion. The packaged object may be tightly wrapped with a shrink film, and the bottom surface of the packaged object may be supported in a state of abutting against the mounting portion. In this case, the upper surface side of the article to be packaged is visibly projected from the opening.

In addition, in the above embodiment, as shown in FIGS. 2 and 4, the adhesive portion 35 is provided so as to extend in the arrow Y direction of the mounting portion 6, but the extending direction of the adhesive portion is Not limited to. For example, the adhesive portion is provided so as to extend in the width direction (the arrow X direction shown in FIGS. 2 and 4) of the placing portion or the first panel portion, and the longitudinal axis of the tubular shrink film is along the direction in which the adhesive portion extends. It may be configured to be arranged and adhered. In this case, after the heat treatment, since the openings of the shrink film are formed on both sides of the mount with the shrink film in the width direction, it is difficult for dust to adhere while the product is displayed. Further, it is also effective for packaging in which the side surface of the object to be packaged is arranged on the front surface.

In the above embodiments and modifications, the example in which the object to be packaged has a substantially cylindrical shape is shown, but the shape of the object to be packaged in the mount with shrink film is not limited to the substantially cylindrical shape, and a cube, a rectangular parallelepiped, a bottle It can be applied to various shapes such as tube shape and tube shape.
