The package A1 of the present embodiment includes a base material 1, a tubular film 2, a joint portion 3, and an object to be packaged 4. The tubular film 2 and the object to be packaged 4 constitute the article of the present invention.

FIG. 1 is a plan view showing a packaging material B1 used for the packaging body A1. FIG. 2 is a plan view showing the package A1. FIG. 3 is a cross-sectional view taken along the line III-III of FIG. FIG. 4 is a perspective view showing the package A1. FIG. 5 is a cross-sectional view showing the package A1. FIG. 6 is a cross-sectional view taken along the line VI-VI of FIG. In these figures, the z direction may be referred to as the "top-bottom direction" and may be described as corresponding to the "vertical direction". Further, in a state where the package A1 is self-supporting or suspended, one side in the z direction may be referred to as "top side" and the other side may be referred to as "ground side". Further, the x direction in the drawing may be referred to as a "width direction" and the y direction may be referred to as a "thickness direction".

The base material 1 holds an article composed of a tubular film 2 and an object to be packaged 4 via a joint portion 3. The base material 1 is mainly a base material such as a general non-coated paper such as thick paper, plain paper, or synthetic paper, or a so-called coated paper having a resin layer on the surface, or synthetic paper. A base material mainly made of a synthetic resin material such as a resin sheet can be adopted. As these, various sheet materials such as a single-layer sheet and a laminated sheet in which two or more of these sheets are laminated and adhered can be used. In the present embodiment, a case where the base material 1 is made of thick paper and a substantially long rectangular mount having four sides extending in the x direction and the y direction is used in the state of the packaging material B1 shown in FIG. 1 will be described as an example. The shape of the base material 1 is not limited at all.

The package A1 shown in FIGS. 2 to 4 is configured by packaging the object to be packaged 4 with the tubular film 2 of the packaging material B1 of FIG. 1 and then appropriately assembling the base material 1. In the following, first, the base material 1 in the packaging material B1 will be described with reference to FIG.

The base material 1 has a main plate portion 11, a back plate portion 12, and a bottom plate portion 13.

The main plate portion 11 is a portion that occupies one side of the base material 1 in the z direction. The main plate portion 11 of the present embodiment has a fixing portion 110, a support portion 111, a front leg portion 112, and a pair of rear locking pieces 115.

The fixing portion 110 is a portion including one end on one side of the main plate portion 11 in the z direction, and is a portion fixed to the back plate portion 12 when the package A1 is constructed, as will be described later. The shape of the fixed portion 110 is not particularly limited, and in the illustrated example, it is substantially rectangular. The main plate portion 11 according to the present invention may have a configuration that does not have the fixing portion 110.

The support portion 111 is a portion where the tubular film 2 is directly joined by the joint portion 3 in the illustrated example. Further, the support portion 111 is used as a portion for realizing a state in which the article composed of the tubular film 2 and the object to be packaged 4 is indirectly joined by the back plate portion 12 in the package A1. As in the example described later, the main plate portion 11 may have a configuration that does not have the support portion 111. In the illustrated example, the support portion 111 is connected to the fixed portion 110. The shape and size of the support portion 111 are not particularly limited, and the tubular film 2 is appropriately joined, and the packaged object 4 packaged in the tubular film 2 in the package A1 is appropriately in the intended posture. It may have a shape and size that can be supported. In the illustrated example, the support portion 111 has a substantially rectangular shape.

The front leg portion 112 is a portion adjacent to the support portion 111, and in the present embodiment, the front leg portion 112 has a pair of hypotenuse portions 1121 and a crossing portion 1122. The pair of hypotenuses 1121 are located on both sides of the support 111 (joint 3) in the x direction (width direction). Further, when the fixing portion 110 is fixed to the back plate portion 12, the hypotenuse portion 1121 is connected to the top side portion of the back plate portion 12 in the z direction. Further, the hypotenuse portion 1121 is connected to the bottom plate portion 13. The crossing portion 1122 is a portion connecting the ground side portions of the pair of hypotenuse portions 1121 in the z direction, and has a shape along the x direction. Further, the crossing portion 1122 is connected to the bottom plate portion 13. In addition, two notches 1123 are formed in the cross section 1122 of the illustrated example. The two notches 1123 are provided near both ends of the cross section 1122 in the x direction. In this embodiment and the modifications and embodiments described later, the configuration may or may not have the notch portion 1123. Further, the specific configuration of the front leg portion 112 is not particularly limited, and for example, a configuration having no crossing portion 1122 may be used. For convenience of assembling the package A1, the support portion 111 and the front leg portion 112 are separated from each other by a cutting line. Further, in the illustrated example, a plurality of connecting portions 118 are provided, for example, in order to prevent the support portion 111 from unreasonably moving with respect to the front leg portion 112. The connecting portion 118 is a portion where a part of the cutting line is interrupted.

The pair of rear locking pieces 115 are portions of the self-standing package A1 described later that come into contact with the article composed of the tubular film 2 and the object to be packaged 4. In the present embodiment, the pair of rear locking pieces 115 project inward in the x direction from the pair of hypotenuses 1121 of the front leg portions 112. In the illustrated example, the rear locking piece 115 is connected to the hypotenuse portion 1121 near the center in the z direction. The illustrated rear locking piece 115 has a semicircular shape, but the shape of the rear locking piece 115 is not particularly limited, and can be various shapes such as a polygonal shape and a semi-elliptical shape. Further, in the illustrated example, a connecting portion 118 is provided at the tip of the rear locking piece 115.

In the illustrated example, the main plate portion 11 is provided with a hanging hole 119. The hanging hole 119 is a portion used for hanging the package A1 in a suspended state, which will be described later. In the illustrated example, the hanging hole 119 is provided at substantially the center of the fixing portion 110 in the x direction and closer to one end in the z direction.

The back plate portion 12 is a portion intended to be located on the back side of the article composed of the tubular film 2 and the object to be packaged 4 in the self-standing package A1 described later. The shape and size of the back plate portion 12 are not particularly limited, and in the illustrated example, the back plate portion 12 has a substantially rectangular shape. Further, the size of the back plate portion 12 in the z direction is smaller than the size of the main plate portion 11 in the z direction.

In the illustrated example, the back plate portion 12 is provided with a hanging hole 129. The hanging hole 129 is a portion used together with the hanging hole 119 for suspending the package A1 in the suspended state described later. In the illustrated example, the hanging hole 129 is provided at substantially the center of the back plate portion 12 in the x direction and closer to the other end in the z direction.

The bottom plate portion 13 is interposed between the main plate portion 11 and the back plate portion 12. The bottom plate portion 13 connects the main plate portion 11 and the back plate portion 12. The shape and size of the bottom plate portion 13 are not particularly limited, and in the illustrated example, the bottom plate portion 13 has a substantially rectangular shape. Further, the size of the bottom plate portion 13 in the z direction in FIG. 1 is smaller than the size of the main plate portion 11 and the back plate portion 12 in the z direction.

In the illustrated example, the base material 1 is provided with planned bending lines FL0 to FL3. The planned bending lines FL0 to FL3 are for facilitating bending at various points when assembling the base material 1 to form the package A1 in the flat state or the self-standing state described later. Such planned bending lines FL0 to FL3 are composed of, for example, a folding ruled line, a perforation line, and the like.

The planned bending line FL0 crosses the middle portion of the bottom plate portion 13 in the z direction in the x direction. In the illustrated example, the planned bending line FL0 is located substantially in the center of the base material 1 in the z direction. The planned bending line FL0 is composed of, for example, a perforation line.

The planned bending line FL1 is provided at the boundary between the fixed portion 110, the support portion 111, and the front leg portion 112. The planned bending line FL2 is provided at the boundary between the front leg portion 112 and the bottom plate portion 13. The planned bending line FL3 is provided at the boundary between the bottom plate portion 13 and the back plate portion 12. The planned folding line FL1 and the planned folding line FL3 are composed of, for example, a folding ruled line. The planned folding line FL2 is composed of, for example, a perforation line and a folding ruled line. Further, the straight line composed of the thin lines shown on the illustrated base material 1 indicates a folding ruled line appropriately provided in addition to the planned bending lines FL1 to FL3. These fold ruled lines are appropriately used when assembling the package A1 or when forming the package A1 other than the states described below.

As a configuration of the base material 1 in the packaging material B1, a configuration in which the main plate portion 11 and the back plate portion 12 are provided on both sides in the z direction with the bottom plate portion 13 interposed therebetween is an example of the configuration. The arrangement of the main plate portion 11, the back plate portion 12, and the bottom plate portion 13 can be changed as long as the package A1 in the flat state or the self-standing state described later can be formed. For example, the back plate portion 12 is connected to the upper side of the main plate portion 11 in the z direction, the bottom plate portion 13 is connected to the lower side of the main plate portion 11 in the z direction in the drawing, and the back plate portion 12 and the bottom plate portion 13 sandwich the main plate portion 11. And may be provided on both sides in the z direction.

The tubular film 2 is a shrink film, a so-called shrink film, and is a member that wraps an object to be packaged 4 in a close contact state by, for example, heat shrinkage. The size and aspect ratio of the tubular film 2 are not particularly limited. The tubular film 2 may have a tubular shape, may have openings on both sides or one side in the z direction in the state shown in FIG. 1, or may be closed on both sides in the z direction. In the illustrated example, the tubular film 2 has openings on both sides in the z direction.

Specific examples of the resin film constituting the tubular film 2 include linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP) and other polyolefin-based materials, and polyethylene terephthalate. Polyester-based, polystyrene-based (PS) such as (PET), polybutylene terephthalate (PBT), and polylactic acid (PLA), polyamide, and ethylene vinyl acetate copolymer (EVA), ethylene-acrylic acid copolymer. Examples thereof include films made of vinyl-based resins such as (EAA) and polyvinyl chloride. Further, a film containing a resin mixture in which two or more kinds of these resins are mixed can be used, or a laminated film in which two or more kinds of films are laminated can be used. In particular, as the heat-shrinkable shrink film, polyester-based, polyolefin-based, and polystyrene-based films are preferable, and polyester-based and polystyrene-based films are particularly preferable, because they have appropriate shrinkage stress and high transparency. Further, a uniaxially stretched film that mainly contracts in the circumferential direction can be preferably used, but a biaxially stretched film that also contracts in the axial direction may be used. The uniaxially stretched film means a film that is substantially uniaxially stretched, and means a film in which the shrinkage ratios in the circumferential direction (so-called TD direction) and the axial direction (so-called MD direction) are significantly different. Therefore, it does not mean only a film that does not shrink at all in either direction (so-called shrinkage rate is zero). Specific examples thereof include a film having a thermal shrinkage rate of 35 to 80% in the circumferential direction and a heat shrinkage rate of −5 to 10% in the axial direction at 90 ° C. for 10 seconds (warm water treatment).

The thickness of the tubular film 2 is not particularly limited, but is preferably 8 to 100 μm, more preferably 10 to 80 μm, and particularly preferably 15 to 60 μm. Further, as the tubular film 2, a colored resin tubular film or a resin film on which a printing layer for displaying a product name, a design, or the like is formed can be used.

In the present embodiment, the tubular film 2 is a heat-shrinkable uniaxially stretched film. The main stretching direction of the tubular film 2 is along the x direction. Such a tubular film 2 has a property that when heated, the heat shrinkage along the x direction is significantly larger than the heat shrinkage along the other directions. Further, such a tubular film 2 can be easily torn along the main stretching direction (x direction) so as to be separated in the z direction.

For example, the joint portion 3 has a strong adhesive strength with the base material 1 and the tubular film 2 constituting the surface layer of the article, withstands the load of the object to be packaged 4, and maintains an adhesive state for a long time in the distribution process and the display process. It can be composed of various adhesives (including adhesives) that can be used. Examples of such adhesives include pressure-sensitive adhesives such as elastomer-based adhesives, thermoplastic resin-based adhesives, and hot-melt adhesives, heat-sensitive adhesives, and the like, and particularly heat-coated cylinders. A hot melt adhesive that exhibits strong adhesive strength when cooled to room temperature after the shape film 2 is attached to the base material 1 is preferable, and a moisture reaction type hot melt adhesive is more preferable. The adhesive strength can be adjusted not only by the type of adhesive but also by the coating area of the adhesive, various additives, and the like, and can be appropriately adjusted according to the weight of the supported object and the like. Further, the joint portion 3 may be formed of a so-called double-sided tape instead of the adhesive.

The object to be packaged 4 is packaged by the tubular film 2, is held by the base material 1 in the package A1, and is protected by the tubular film 2. As the object to be packaged 4, various products sold in stores are adopted, and any product that can be packaged by the tubular film 2 may be used. In the illustrated example, a bottle container containing a liquid content is adopted as the object to be packaged 4. When the article is composed of only the object to be packaged 4, the tubular film 2 may not be provided. In this case, the object to be packaged 4 is directly joined to the base material 1 by the joint portion 3.

2 and 3 show the package A1 in a flat state. To form the package A1, first, the tubular film 2 of the packaging material B1 shown in FIG. 1 is expanded, and the packaged object 4 is inserted through one of the openings. Then, for example, the tubular film 2 is heat-shrinked by heating the tubular film 2 to a predetermined temperature. Due to this heat shrinkage, the tubular film 2 shrinks remarkably in the x direction and covers the packaged object 4 in a close contact state.

Next, the base material 1 is bent at the planned bending line FL0. As a result, the bent portion BL0 shown in FIGS. 2 and 3 is formed. Further, the fixing portion 110 and the back plate portion 12 are joined by the base material joining portion 39, and the support portion 111 and the back plate portion 12 are joined by the base material joining portion 38. The base material joint portion 38 and the base material joint portion 39 can have the same configuration as the joint portion 3 described above, and are composed of, for example, double-sided tape.

By the above steps, the package A1 shown in FIGS. 2 and 3 is obtained. The base material 1 of the package A1 has a configuration in which the z-direction top side portions of the main plate portion 11 and the back plate portion 12 are fixed to each other. In the illustrated example, the article composed of the tubular film 2 and the object to be packaged 4 is indirectly joined to the back plate portion 12 via the support portion 111 by the joint portion 3.

Further, in this base material 1, the bottom plate portion 13 is folded by the bent portion BL0, and the main plate portion 11 including the support portion 111 and the front leg portion 112 is in a flat state along the back plate portion 12. The package A1 in this state is a package A1 in a flat state. As shown in FIG. 3, the package A1 can be suspended from the suspension hook 91 by inserting the suspension hook 91 through the suspension hole 119 and the suspension hole 129.

Further, after forming the package A1 in a flat state, or without passing through the package A1 in a flat state using the packaging material B1 and the object to be packaged 4, the package A1 in the state shown in FIGS. It may be formed. That is, the planned bending line FL1 in FIG. 1 is bent to form the bending portion BL1, the planned bending line FL2 is bent to form the bending portion BL2, and the planned bending line FL3 is bent to form the bending portion BL3. As a result, the front leg portion 112, the back plate portion 12, and the bottom plate portion 13 provide a structure having a triangular shape in the x-direction view.

As shown in FIG. 5, the angle θ3 formed by the back plate portion 12 with the bottom plate portion 13 is larger than the angle θ2 formed by the front leg portion 112 with the bottom plate portion 13. Further, the angle θ1 formed by the front leg portion 112 and the back plate portion 12 is smaller than the angle θ2. In the illustrated example, the angle θ3 is a substantially right angle, and the front leg portion 112, the back plate portion 12, and the bottom plate portion 13 have the front leg portion 112 as the hypotenuse and the back plate portion 12 stands at a right angle along the z direction. It constitutes a triangular shape.

Further, as shown in FIG. 6, when forming a right-angled triangular portion including the front leg portion 112, the back plate portion 12, and the bottom plate portion 13, the pair of rear locking pieces 115 of the main plate portion 11 are attached to the tubular film 2 And the article made of the object to be packaged 4 is brought into contact with the article from the rear in the y direction. Due to this contact, a pair of rear locking pieces 115 are interposed between the back plate portion 12 and a part of the article made of the tubular film 2 and the object to be packaged 4. As shown in FIG. 4, by bringing the pair of rear locking pieces 115 into contact with the article made of the tubular film 2 and the object to be packaged 4 from the rear in the y direction, the pair of hypotenuses 1121 are brought into contact with the pair of rear parts. The portion connected to the locking piece 115 is slightly moved rearward in the y direction, and the entire oblique side portion 1121 has a curved shape that gently bulges rearward in the y direction.

As shown in FIG. 5, for example, the packaging body A1 in the state shown in FIGS. 4 and 5 can stand on its own in a posture in which the bottom plate portion 13 abuts on the shelf surface 92 of the display shelf, and the packaging body in the self-standing state. It is A1. The front leg portion 112 has an opening 1129 because the support portion 111 is joined to the back plate portion 12. The front leg portion 112 intersects the packaged object 4 in the x-direction, and the packaged object 4 is inserted through the opening 1129.

Next, the operation of the package A1 will be described.

For example, when the packaged object 4 tends to fall forward in the y direction in the self-standing package A1, this force deforms the right-angled triangular shape formed by the front leg portion 112, the back plate portion 12, and the bottom plate portion 13. Acts like. According to the research by the inventors, this deformation was mainly in a mode in which the hypotenuse 1121 was curved so as to bulge forward in the y direction. In the present embodiment, as shown in FIGS. 4 to 6, a pair of rear locking pieces 115 are in contact with an article composed of the tubular film 2 and the object to be packaged 4 from the rear in the y direction. Therefore, the hypotenuse portion 1121 can suppress the movement of the hypotenuse portion 1121 forward in the y direction, and prevent the hypotenuse portion 1121 from bending so as to bulge forward in the y direction. Therefore, it is possible to more reliably maintain the self-supporting state of the package A2.

As shown in FIG. 5, in the illustrated example, the packaged object 4 is separated from the bottom plate portion 13 on the top side in the z direction. As a result, when the package A1 is impacted from below in the z direction, it can be expected that the gap between the packaged object 4 and the bottom plate portion 13 exerts a cushioning effect. On the other hand, the packaged object 4 is not directly supported by the bottom plate portion 13, but is supported in a state of being greatly projected forward in the y direction from the back plate portion 12. Therefore, the weight of the object to be packaged 4 acts remarkably so as to tilt the object to be packaged 4 forward in the y direction. In the present embodiment, the front leg portion 112, the back plate portion 12, and the bottom plate portion 13 have a triangular shape by abutting the rear locking piece 115 from the rear in the y direction on the article composed of the tubular film 2 and the packaged object 4. Can be maintained more firmly, and it is preferable to prevent the object to be packaged 4 from tilting forward in the y direction.

The front leg portion 112 has a pair of hypotenuse portions 1121, and a pair of rear locking pieces 115 are individually connected to the pair of hypotenuse portions 1121. As a result, the pair of hypotenuses 1121 can be held in a well-balanced manner in the x direction by the pair of rear locking pieces 115, which is advantageous for more reliable independence.

Further, as shown in FIG. 6, in the illustrated example, the rear locking piece 115 protruding from the hypotenuse portion 1121 abuts on the article made of the tubular film 2 and the packaged object 4 from the rear side in the y direction. In addition, it is in a state of bending backward in the y direction. As a result, a repulsive force is generated on the rear locking piece 115 (hypotenuse 1121), and unintended movement of the hypotenuse 1121 can be suppressed more firmly. Further, the hypotenuse portion 1121 has a twisted shape due to the bending of the rear locking piece 115. This also makes it possible to more preferably suppress the unintended movement of the hypotenuse portion 1121. In order to exert the effect of suppressing the movement of the hypotenuse portion 1121 due to such repulsive force and the twisted shape, a portion such as a fold ruled line that can be easily bent is provided between the hypotenuse portion 1121 and the rear locking piece 115. A configuration that does not have is preferable.

By providing the two cut portions 1123 in the crossing portion 1122, the portion of the crossing portion 1122 sandwiched between the two cut portions 1123 can swing back and forth in the y direction. As a result, in assembling the self-standing package A1 shown in FIGS. 4 to 6, when the article composed of the tubular film 2 and the packaged object 4 together with the support portion 111 is moved rearward in the y direction with respect to the front leg portion 112. In addition, when the packaged object 4 can interfere with the crossing portion 1122, the portion can be retracted forward or backward in the y direction to avoid interference with the packaged object 4.

Further, in the present embodiment, the package A1 takes a flat state shown in FIGS. 2 and 3 and a self-supporting state shown in FIGS. 4 to 6. Therefore, the package A1 can be selected from, for example, a display in a suspended state as shown in FIGS. 2 and 3, and a display in an independent state as shown in FIGS. 4 to 6. Therefore, a wider variety of display forms can be realized.
