Description

Technical Field

[0001] The present invention relates to a bundling label and a package.

Background Art

[0002] When selling a plurality of articles in a batch, conventionally, an integrated packaging form in which these articles are stacked and the entire outside thereof is wrapped with an outer bag has generally been adopted. However, in recent years, as a simple packaging form for the purpose of reducing environmental load, etc., a form using a rectangular bundling label instead of an outer bag has been proposed.

[0003] For example, in Patent Document 1, bundling labels are respectively attached to a pair of side surface portions facing in a direction orthogonal to the stacking direction of articles so as to straddle the boundary portion between articles, and a plurality of articles are bundled by the pair of bundling labels. A packaging form is disclosed.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, referring to FIG. 12, for example, when trying to bundle and attach a bundling label 2 to the side surface of a product of three packs of articles 1a, 1b, 1c each having a container with a flange portion 13 on the outer periphery of the side, such as retort rice, there is a lot of space between the article 1b in the second row (middle row) and the bundling label 2, and the adhesion area of the bundling label 2 to the article 1b is small. Therefore, there is a possibility that the article 1b in the second row may shift and fall off during transportation or the like.

[0006] An object of the present invention is to provide a binding label that is adhered so as to straddle a boundary portion between articles in order to bind three or more articles, and that can suppress movement (displacement) of the articles due to an external force in a state where the three or more articles are bound.

Means for Solving the Problems

[0007] The binding label of the present invention is a binding label that is adhered so as to straddle a boundary portion between articles in order to bind three or more articles, at least one of the articles is a movable article, and has a folded portion adhered to the movable article, wherein the movable article is an article that may move due to an external force if the folded portion is not adhered in a state where the three or more articles are bound, and the folded portion is adhered to the movable article so as to suppress movement of the movable article.

Effects of the Invention

[0008] According to the present invention, it is possible to provide a binding label that is adhered so as to straddle a boundary portion between articles in order to bind three or more articles, and that can suppress movement (displacement) of the articles due to an external force in a state where the three or more articles are bound.

Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same parts or common parts are denoted by the same reference numerals.

[0011] <Binding label> Referring to FIGS. 1 and 2, the binding label 2 of the present embodiment is a binding label 2 that is attached so as to straddle the boundary portion between articles in order to bind three or more articles 1a, 1b, 1c.

[0012] (Article) The article is not particularly limited, but for example, it is various products sold in a bound state.

[0013] The article may be composed of, for example, a content and a container capable of storing the content. The content is not particularly limited, but examples thereof include food, beverages, cosmetics, drugs, and the like. The container is not particularly limited, but examples thereof include a bottle container, a can container, a sheet molding container (tray container, blister container), a bag body, a box body, etc. that can store the content. The material of the container is not particularly limited, but it is preferably a material such that the container does not break even when the binding label is peeled off after being attached. For example, three or more articles are bound by a detachably attached binding label, and when using the articles, the individual articles can be taken out by peeling off the binding label. Examples of the material of the container include resin, metal, paper, and the like.

[0014] Note that the article may be, for example, the product itself without packaging such as a battery. When the article is the product itself, it is preferable that the product is not damaged in appearance due to the attachment and detachment of the binding label.

[0015] Note that in the drawings, the shape of the articles 1a, 1b, 1c in plan view is rectangular, but it is not limited thereto, and may be, for example, circular, elliptical, or the like.

[0016] (Movable article) At least one of the articles is the movable article 1b. The movable article 1b is an article that can move (shift) by an external force if the folding portion 21 described later is not attached in a state where three or more articles 1a, 1b, 1c are bound.

[0017] The movable article 1b, for example, is in contact with the binding label 2 in a state where the folding portion 21 is not attached, but the area of the contact portion (attachment portion) is small (see FIGS. 2 to 5, FIGS. 7 to 9), or the adhesive force of the binding label 2 is weak. Therefore, the fixing force by the binding label 2 is weak, and the article 1b may be an article that can move (relatively easily) by an external force (such as gravity or stress during conveyance), or the article 1b that is not in contact with the binding label 2 (an article that is only sandwiched between other articles) in a state where the folding portion 21 is not attached (see FIG. 6) may also be used.

[0018] (Base material, adhesive layer) The binding label 2 may be, for example, in a sheet shape. The sheet-shaped bundling label 2 includes, for example, a base material and an adhesive layer formed on one surface of the base material. The bundling label 2 can be attached to an article via the adhesive layer.

[0019] The base material of the bundling label may be, for example, a resin film or paper (paper base material). Examples of the material of the resin film include polyolefin-based resins such as polyethylene-based resins, polypropylene (PP)-based resins, cyclic olefin-based resins, copolymer polymers containing polyethylene, etc., polyester-based resins such as polyethylene terephthalate (PET), polyamide-based resins, polystyrene-based resins, and (meth)acrylic-based resins. The paper preferably contains paper material (pulp) as a main component (50% by mass or more). The pulp content in the paper base material is preferably 80% by mass or more, more preferably 90% by mass or more, and still more preferably 95% by mass or more. Examples of such paper base materials include unprocessed papers such as ordinary paper (medium-quality paper), high-quality paper, and synthetic paper, and processed papers such as coated paper (waterproof paper), glossy paper, and matte paper. Note that the bundling label may be, for example, processed paper such as glassine paper, sulfuric acid paper, paraffin paper, or cellophane. Note that when the material of the bundling label contains plant-derived materials, biomass-derived materials, recycled materials, biodegradable materials, or natural materials, the environmental load can be further reduced.

[0020] The thickness of the base material of the bundling label is not particularly limited, but is preferably 15 to 300 μm, and more preferably 20 to 150 μm.

[0021] The adhesive layer is a layer containing an adhesive for attaching the bundling label. The adhesive layer can be formed by applying an adhesive to one surface (back surface) of the base material. The adhesive is not particularly limited, and for example, an ultraviolet-curable hot melt adhesive (such as an ultraviolet-curable acrylic-based hot melt adhesive) can be used.

[0022] The adhesive layer is preferably peelable. If the adhesive strength of the adhesive layer of the binding label is too high, it will be impossible to easily peel off the binding label when taking out one of three or more articles. Therefore, the adhesive strength of the adhesive layer is preferably a strength below a predetermined value at which peeling can be easily performed. However, it is also possible to take out individual articles during use of the article by cutting out the portion (such as the folded portion) of the binding label attached to the article from the binding label. Therefore, in such a case, the adhesive layer does not necessarily have to be peelable.

[0023] Note that a printed layer with characters, designs, etc. may be formed on the front surface (the surface opposite to the adhesive layer of the base material) of the binding label. As the ink for forming the printed layer, for example, ultraviolet curable ink or the like can be used. Furthermore, a transparent cover layer for protecting the printed layer may be provided on the surface of the printed layer.

[0024] (Folded portion) The binding label 2 has a folded portion 21 that is attached to the movable article 1b described above. The folded portion 21 is a bendable portion and can be attached to the movable article 1b by folding it toward the movable article 1b side with respect to other portions (see Fig. 1).

[0025] The folded portion 21 is attached to the movable article 1b so as to suppress the movement (displacement) of the movable article 1b. The adhesion area of the folded portion to the movable article is preferably an area equal to or larger than a predetermined value such that when an external force is applied to the movable article, the binding label 2 does not peel off from the movable article 1b and can suppress the movement of the movable article. The shape of the attachment portion of the folded portion to the movable article is also preferably a shape such that when an external force is applied to the movable article, the binding label 2 does not peel off from the movable article 1b and can suppress the movement of the movable article. For example, in order to suppress the movement of the movable article 1b in the displacement direction S, it is preferable to make the length (width) of the folded portion in the displacement direction S equal to or longer than a predetermined length at which the displacement can be suppressed.

[0026] The folding portion 21 can be formed, for example, by providing a cut 21a in a bundling label 2 having a shape such as a rectangular shape (see FIG. 10). Note that, for example, instead of the cut 21a, a breakable portion such as a perforation may be provided, and the folding portion 21 may be folded while breaking the breakable portion so that the folding portion is adhered to the movable article 1b. Alternatively, the folding portion 21 may be provided by manufacturing a bundling label 2 having a shape with the folding portion 21 from the beginning (see FIG. 11). Note that the folding portion 21 is folded at the location of the dotted line (folding line) in FIGS. 10 and 11 and adhered to the movable article 1b.

[0027] In the present embodiment, for example, three or more articles 1a, 1b, 1c are bundled in a state of being stacked in one stacking direction D (see FIGS. 1 to 8). Each of the three or more articles 1a, 1b, 1c has a first surface 11 which is a surface on the first direction D1 side which is one side of the stacking direction D, and a second surface 12 which is a surface on the second direction D2 side which is a direction opposite to the first direction D1. Here, the movable article 1b is at least one article sandwiched between the article 1a on the most first direction D1 side and the article 1c on the most second direction D2 side.

[0028] The bundling label is adhered to three or more articles 1a, 1b, 1c stacked in one stacking direction D so as to straddle the boundary portion in the stacking direction D between the articles 1a, 1b, 1c on its side surface (a plane located at the outer peripheral end of the article in a plan view seen from the stacking direction D and parallel to the stacking direction D).

[0029] Note that the three or more articles do not have to be stacked in one stacking direction D, and may be bundled in any state. The three or more articles can be bundled such that each of the articles is in contact with at least one other article. For example, the three or more articles 1a, 1b, 1c may be bundled in a state like a straw stack (see FIG. 9).

[0030] The thickness (distance between the first surface 11 and the second surface 12) of the movable article 1b in the stacking direction D shown in FIGS. 2 to 5 and FIG. 8 is thinner at the outer peripheral portion than at the central portion 101 (portion where the first surface 11 and the second surface 12 are substantially parallel) in a plan view seen from the stacking direction D (see FIG. 3 in particular). When the thickness of the movable article 1b is thin on the outer peripheral portion 102 side, the sticking area of the binding label 2 on the side surface side of the movable article 1b becomes small, so it is difficult to sufficiently fix the movable article 1b with the binding label 2. For this reason, the folding portion 21 is attached to at least one (or a part) of the first surface 11 and the second surface 12 of the movable article 1b, for example. Thereby, the movable article 1b is prevented from moving (shifting) in the deviation direction S (a direction perpendicular to the stacking direction D and parallel to the side surface to which the binding label is attached).

[0031] When binding three or more articles 1a, 1b, 1c stacked in one stacking direction D, in the movable article 1b, for example, the thickness of the outer peripheral portion 102 (especially the outer peripheral end) in a plan view is a predetermined thickness or less such that the movable article 1b can move (shift) due to an external force. That is, in the movable article 1b, the area of the side surface of the movable article 1b to which the binding label 2 can be attached without the folding portion 21 is a predetermined area or less such that the movable article 1b can move (shift) due to an external force. For example, when the article is a container (such as a retort food tray container, a blister container, or a pouch container) formed by welding the outer peripheral end portion of a sheet-like member, the thickness of the outer peripheral end portion (flange portion) of the article is about twice the thickness of the sheet-like member, and particularly the thickness of the outer peripheral end of the article is thin. When the thickness of the outer peripheral end portion of the article is thin in this way, the movable article 1b is likely to shift. Therefore, in particular, the effect of suppressing the shift of the movable article 1b by attaching the folding portion 21 of the binding label 2 of the present embodiment to at least one of the first surface 11 and the second surface 12 at the outer peripheral end portion (welding portion of the sheet-like member) of the movable article 1b is useful.

[0032] In FIG. 2, all of the three or more articles 1a, 1b, 1c have the same shape as the movable article 1b described above. However, the present invention is applicable as long as at least the movable article 1b has such a shape (see FIG. 5).

[0033] When the thicknesses of all of the three or more articles 1a, 1b, 1c in the stacking direction are thinner at the outer peripheral portion 102 than at the central portion 101 in a plan view seen from the stacking direction, that is, the thicknesses of the outer peripheral ends of the articles 1a, 1c other than the movable article 1b are also thin, the sticking area of the binding label on the side surface also becomes small for the articles 1a, 1c other than the movable article 1b. In such a case, it is preferable that the binding label 2 is also stuck to the first surface 11 (a part thereof) of the article 1a on the most first direction D1 side and the second surface 12 (a part thereof) of the article 1c on the most second direction D2 side. For example, one end portion 2a of the binding label 2 is stuck to the first surface 11 of the article 1a, and the opposite end portion 2b of the binding label 2 is stuck to the second surface 12 of the article 1c. Thereby, the sticking area of the binding label 2 to the articles 1a, 1c other than the movable article 1b is secured, and the articles 1a, 1c can be sufficiently fixed.

[0034] The binding label 2 is preferably stuck to two opposing side surfaces of the three or more articles 1a, 1b, 1c that are overlapped (see FIGS. 1 to 8). The two side surfaces are, for example, a pair of side surfaces that face in a direction orthogonal to the stacking direction D (stacking direction) of the articles.

[0035] For example, when the bundling label is attached to the four sides (e.g., four sides when the article is rectangular in plan view) of the sides of three or more stacked articles, even if the attachment area to the article is small, the middle article 1b will not become a movable article, or even if the middle article 1b is a movable article without contacting the bundling label, the article 1b will not fall off. Therefore, there is little need to fix the movable article (the middle article 1b) by the folding portion. For this reason, for example, when the bundling label having the folding portion of the present embodiment is attached only to two opposite sides of three or more stacked articles 1a, 1b, 1c, it is particularly useful.

[0036] In this case, each of the two bundling labels 2 may be attached to the two sides (as shown in FIGS. 1, 2, etc.), or one bundling label may be attached to the range including the two sides. In the latter case, for example, one bundling label may be attached to the range covering at least one of the first surface 11 of the article 1a and the second surface 12 of the article 1c and the two sides.

[0037] Further, the folding portion 21 may be provided at any of the central portion, both side ends, and one side end of the bundling label 2 in the displacement direction S of the movable article 1b. In FIG. 1, the folding portion 21 is provided at one side end of the bundling label 2 in the displacement direction S. When the folding portion 21 is provided only at one side end of the bundling label 2, in a plan view seen from the stacking direction D, it is preferable that the folding portions 21 of the bundling labels 2 attached to the two opposite sides are arranged diagonally (at a substantially rotationally symmetric position about the stacking direction D). In this case, since an equal restraining force acts on the displacements to both sides in the displacement direction S, the displacement of the movable article 1b can be more reliably restrained.

[0038] In addition, in order to make the folding portion 21 foldable toward the movable article 1b side with respect to the articles 1a, 1b, 1c as shown in FIGS. 1 to 8, it is preferable to set the length of the folding portion 21 (the length in the direction perpendicular to the folding line) to be shorter than the height of one stage of each article (the thickness of the central portion 101).

[0039] It is preferable that the folding portion 21 is provided with a break prevention portion 21b for preventing the breakage of the binding label 2 due to the displacement of the movable article 1b. The break prevention portion 21b is not particularly limited as long as it can prevent the breakage of the binding label 2. For example, as shown in FIGS. 10(a), (b) and 11, a cut that extends roundabout in the displacement direction S of the movable article 1b from the end portion (outer peripheral end) of the folding line of the folding portion 21 can be mentioned. Here, "extending roundabout in the displacement direction S" means extending in a direction different from the displacement direction S while extending in the displacement direction S as a whole. In addition, the shape of the break prevention portion 21b is U-shaped and square-shaped in FIGS. 10 and 11, but is not particularly limited thereto, and may be a circular hole or the like.

[0040] When the movable article 1b moves in the displacement direction, if the outer peripheral end of the folding portion 21 (for example, the end of the cut forming the folding portion 21) faces a direction close to the displacement direction S, a crack may occur in the displacement direction S of the movable article 1b from that end. When the distance of the end from the end portion in the width direction of the binding label 2 is short, the binding label 2 may be cut by this crack. On the other hand, due to the cut (break prevention portion 21b) that extends roundabout in the displacement direction S of the movable article 1b, the direction of the stress in the displacement direction S applied to the end portion of the folding line is changed (a stress relief field is created), and the force of being torn in the displacement direction S from the end portion of the folding line is relaxed. Therefore, the breakage (cutting) of the binding label can be prevented.

[0041] For example, as shown in FIG. 7, even when the articles 1a, 1b, 1c have convex portions 14 (for example, the winding tightening portion of a can container) protruding laterally, the folding portion of the binding label of the present embodiment is effective. For the articles 1a, 1b, 1c in FIG. 7, the binding label 2 is sufficiently adhered to the article 1a and the article 1c by an end portion 2a adhered to the first surface of the article 1a and an end portion 2b adhered to the second surface 12 of the article 1c. However, on the side surface, due to the convex portion 14, the binding label 2 is adhered only to the convex portion 14 with respect to the articles 1a, 1b, 1c (if there is no folding portion 21), and the article 1b may shift. Therefore, by adhering the folding portion 21 to the side surface of the movable article 1b, the shift of the movable article 1b can be suppressed.

[0042] <Package> The package 3 of the present embodiment is a package in which three or more articles 1a, 1b, 1c are bound by the above-described binding label 2. At least one of the articles is a movable article 1b. As described above, the movable article is the article 1b that may move by an external force if the folding portion 21 is not adhered in a state where three or more articles 1a, 1b, 1c are bound. The folding portion 21 of the binding label 2 is adhered to the movable article 1b so that the movement of the movable article 1b is suppressed.
