[0011] Hereinafter, one embodiment of the present disclosure will be described with reference to Fig. 1 etc. First, a package 1 according to the present disclosure will be described, and then the configurations of a flat bag 10, a backing sheet 30, etc., which constitute the package 1 will be described.

[0012] (packaging) FIG. 1 is a schematic diagram showing an example of a package 1 according to one embodiment of the present disclosure. Reference numeral 101 in FIG. 1 is a diagram showing the package 1 according to one embodiment of the present disclosure, which is composed of a flat bag 10 and a backing sheet 30, as viewed obliquely from below the bottom surface. In the diagram shown by reference numeral 101 in FIG. 1, the backing sheet 30 is inserted from the lower end of the flat bag 10. Reference numeral 102 in FIG. 1 is a diagram showing the package 2 according to another embodiment of the present disclosure, which is composed of a flat bag 10 and a backing sheet 60, as viewed obliquely from above the front surface. In the diagram shown by reference numeral 102 in FIG. 1, the backing sheet 60 is inserted from the upper end of the flat bag 10.

[0013] In Fig. 1, an XYZ coordinate system is shown. The X axis indicates the width direction of packaging body 1 and packaging body 2. The Y axis indicates the thickness direction of packaging body 1 and packaging body 2. The Z axis indicates the height direction of packaging body 1 and packaging body 2. On the Z axis, the direction of gravity is the downward direction, and the opposite direction is the upward direction. In the following explanation, a numerical range expressed as "lower limit value XXX to upper limit value YYY" means equal to or greater than the lower limit value XXX and equal to or less than the upper limit value YYY.

[0014] Referring to the diagram indicated by reference numeral 101 in Fig. 1, the package 1 is a package in which an article 100 is packaged, and is displayed at a storefront such as a drugstore or supermarket. The package 1 includes the article 100, a flat bag 10 that does not have a specific structure for forming a side gusset, and a backing paper 30 that supports the article 100.

[0015] 1, the article 100 is a tube container with an oval cross section on the cap side supported on the mount 30 so that the tail portion, which is the flat sealed end side, faces upward (upward on the Z axis) and the head portion, which is the cap side, faces downward (downward on the Z axis). The article 100 may be supported on the mount 30 by being clamped in a notch provided in the mount, or by adhesive, double-sided tape, a shrink film adhered to the mount, blister packaging, or the like.

[0016] The article 100 contains, for example, cosmetics such as cream or gel, detergent, shampoo, rinse, medicine, or food. The article 100 may contain various contents such as solids, liquids, or powders. The article 100 is not limited to a specific shape or size. As an example, the article 100 may have a cylindrical shape such as lipstick or a dry cell, or a prismatic shape.

[0017] The flat bag 10 does not have a unique structure for forming a side gusset by itself, and is a bag that appears flat when no contents are inserted. The flat bag 10 does not have a side gusset for the thickness of the contents. As will be described later, the package 1 according to the present disclosure is a package that stores a mount 30 on which an article 100 is placed, and forms a side gusset at the position of the taper 31T by the taper 31T and the base 32 of the main surface portion 31. Therefore, the flat bag 10 is a bag in which the side gusset is formed at the position of the taper 31T by the taper 31T and the base 32 of the main surface portion 31 by inserting the mount 30. In contrast, a conventional envelope with a side gusset does not expand unless an article is inserted, but since the side gusset is formed in advance, it can be said to have a structure for forming a side gusset by itself.

[0018] As an example, the flat bag 10 is a paper envelope formed by overlapping both widthwise edge portions of rectangular paper and bonding them with an adhesive (envelope pasting), and forming a flat tubular shape with both widthwise ends as folds. The type of envelope pasting may be either center pasting or side pasting (corner pasting). When forming a flat bag from a plastic film, in addition to envelope pasting like paper, it may be formed by melt-cut sealing that leaves almost no seal width (so-called side seal width) on both widthwise ends. Further configuration of the flat bag 10 will be described later with reference to FIG. 2.

[0019] In the present disclosure, the material of the flat bag 10 is not limited to a specific material, and examples include paper or plastic film. Due to marine pollution caused by plastic, problems with the depletion of fossil fuels, and environmental measures to reduce greenhouse gases such as CO2, the use of paper substrates as an alternative material to plastic has been attracting attention. Therefore, in the following, the flat bag 10 will be described as being made of paper.

[0020] The flat bag 10 is not limited to a specific shape or size, and may be a square, a trapezoid, or the like when viewed from above when no contents are placed inside. In the following description, the flat bag 10 will be described as being rectangular when viewed from above when no contents are placed inside. The flat bag 10 will be described later with reference to FIG. 2.

[0021] The mount 30 is inserted into the flat bag 10 from the open end (upper end or lower end) of the flat bag 10 while supporting (placing) the article 100. In the reference numeral 101 in FIG. 1, the mount 30 is inserted into the flat bag 10 from the lower end of the flat bag 10 while supporting (placing) the article 100. As will be described in detail later, the mount 30 has a gripping portion 36 that stands upright relative to the bottom surface portion 32A, and an opening is formed in the bottom surface portion 32A by the gripping portion 36 standing upright. The mount 30 allows a user to insert a finger into the opening and grip the gripping portion 36, making it easy to insert the mount 30 into the flat bag 10 and to pull out the mount 30 from the flat bag 10. The size and / or shape of the mount 30 may be determined so as to fit the flat bag 10.

[0022] Details will be described later with reference to FIG. 3 etc., but the backing 30 has a taper (not shown) tapering downward (downward in the Z-axis direction). Therefore, by inserting the backing 30 into the flat bag 10 that does not have a specific structure for forming a side gusset, a space is created between the taper of the backing 30 and the flat bag 10. The existence of this space allows the flat bag 10 to follow the shape of the backing 30, and a side gusset 10T corresponding to the depth (Y-axis direction) of the backing 30 is formed. As a result, when inserted into the flat bag 10, the backing 30 maintains an upright state, and a bottom gusset can be formed in the package 1.

[0023] Here, the term "gusset" generally means the thickness, depth, or width of a bag or envelope. The side gusset means a gusset on the side of a bag or envelope. The bottom gusset means a gusset on the bottom of a bag or envelope. As described above, the flat bag 10 can follow the shape of the backing paper 30 and form a side gusset 10T corresponding to the depth (Y-axis direction) of the backing paper 30. The side gusset 10T allows the package 1 to form a bottom gusset (width in the Y-axis direction) that did not exist before inserting the backing paper 30 into the flat bag 10 by inserting the backing paper 30 into the flat bag 10. In general, the bottom gusset of the package 1 is formed by the bottom flap 13. However, the bottom gusset can be considered to be formed by the bottom flap 13 of the flat bag 10 and the base 32 of the backing paper 30, or, if the bottom flap 13 does not exist, the bottom gusset can be considered to be formed by the base 32 of the backing paper 30.

[0024] Continuing to refer to reference numeral 101 in Fig. 1, the flat bag 10 has, but is not limited to, a hole 19. Furthermore, the mount 30 has a hole (not shown) at a position corresponding to the hole 19. This allows the package 1 to be displayed in a hanging manner in a drugstore or the like.

[0025] The flat bag 10 has, but is not limited to, a transparent region 18 so that the item 100 stored in the package 1 can be seen from the outside (details will be described later). The transparency, position, shape, etc. of the transparent region 18 can be changed as desired. By having the transparent region 18, the design of the package 1 can be improved, and the commercial value of the package 1 can be increased.

[0026] In the package 1 indicated by reference numeral 101 in FIG. 1, the flat bag 10 does not have a bottom flap 13 (described later), but the flat bag 10 may have a bottom flap 13.

[0027] Next, a package 2 according to the present disclosure will be described with reference to the diagram indicated by reference numeral 102 in Fig. 1. The contents described with reference to the diagram indicated by reference numeral 101 in Fig. 1 will not be described again.

[0028] The package 2 is a package in which an article 100 (not shown) is packaged, and is displayed at a storefront such as a drugstore or supermarket. The package 2 includes the article 100, a flat bag 10, and a backing 60. The backing 60 is inserted into the flat bag 10 from the upper end thereof while supporting (arranging) the article 100. The flat bag 10 has, but is not limited to, a bottom flap 13, which can close the lower end of the flat bag 10. The timing of closing the lower end of the flat bag 10 with the bottom flap 13 may be either before or after the backing 60 is inserted into the flat bag 10. In the present disclosure, the bottom flap 13 is used to close the lower end of the flat bag 10. The bottom gusset of the package is formed by inserting the backing 30 into the flat bag 10.

[0029] In the package 2, when inserting the backing 60 into the open end (upper end) of the flat bag 10, the base 62 (not shown, described below) of the backing 60 may get caught on the open end of the flat bag 10, or friction between the base 62 and the flat bag 10 may make it difficult to insert the backing 60 into the flat bag 10. The backing 60 may have a sliding structure to solve this problem (described below with reference to FIGS. 6 to 8).

[0030] Next, the flat bag 10, the backing paper 30, etc. will be described.

[0031] (flat bag) First, the flat bag 10 into which the backing paper is inserted will be described with reference to Fig. 2. Fig. 2 is a diagram showing a specific example of the flat bag 10 according to one embodiment of the present disclosure. Reference numeral 201 in Fig. 2 indicates a front view of the flat bag 10. Reference numeral 202 in Fig. 2 indicates a rear view of the flat bag 10. Note that in Fig. 2, the bottom flap 13 is not adhered to the side (also referred to as "upper front") 14 and the glue bottom (also referred to as "lower front") 15, and is shown in an unfolded state.

[0032] 2, the flat bag 10 is composed of a surface 11, a flap 12, a bottom flap 13, a side 14, a glued bottom 15, and a side bottom 16. The flat bag 10 may be composed of a single sheet. If the package 1 is capable of being displayed in a store, the flat bag 10 does not need to have the flap 12, the bottom flap 13, and / or the side bottom 16.

[0033] The flat bag 10 in Fig. 2 is a paper envelope formed by overlapping both widthwise edge portions of a rectangular piece of paper and joining them with an adhesive (envelope pasting) to form a joint AD, and then forming a flat tubular shape with folds F on both widthwise ends after forming joint AD. By having folds F, the flat bag 10 can easily form side gussets that follow the backing paper 30, and prevents protrusions from forming on the surfaces of the side gussets. S1 in Fig. 2 indicates the inside dimension of the flat bag 10.

[0034] The flat bag 10 may be made of a material selected from uncoated paper, one-side gloss kraft paper in which one side of the substrate is treated, bleached kraft paper, unbleached kraft paper, and the like. In terms of improving the transparency of the transparent region 18 described below and the printability of the surface, when the transparent region 18 is formed, the flat bag 10 is preferably made of one-side gloss bleached kraft paper. The flat bag 10 is preferably made of, but not limited to, one-side gloss bleached kraft paper having a thickness of 30 g / m 2 ~120g / m 2 , preferably 40 g / m 2 ~100g / m 2 The basis weight may be

[0035] The surface 11, flap 12, sides 14, and bottom adhesive 15 may conform to known envelope structures, and detailed description thereof will be omitted.

[0036] The bottom flap 13 extends downward in the Z-axis direction from the surface 11. The length of the bottom flap 13 in the Z-axis direction may be determined according to the length in the Z-axis direction of the base 32 of the mount 30, the base 62 of the mount 60, or the base 92 of the mount 90, which will be described later with reference to Figures 3, 6, and 9, respectively. The bottom flap 13 may have a double-sided tape at its tip 13A, and the double-sided tape is adhered to the side 14 and the glued underside 15 when the bottom flap 13 is folded back in the direction of the side 14 and the glued underside 15. The tip 13A may be adhered to the side 14 and the glued underside 15 by an adhesive or the like.

[0037] The bottom flap 13 is not formed over the entire width direction (X-axis direction) of the packaging body 1. Side bottoms 16 are provided at both ends of the packaging body 1 in the X-axis direction.

[0038] The side bottom 16 extends downward in the Z-axis direction from both ends of the surface 11 in the X-axis direction. Although not limited thereto, a gap 16K is provided between the side bottom 16 and the bottom flap 13, and the side bottom 16 is not connected to the bottom flap 13. With reference to the diagram indicated by reference numeral 201 in FIG. 2, the side bottom 16 has a width D16 in the X-axis direction. Although not limited thereto, the width D16 is set to about 50% of the thickness direction of the base 32 of the mount 30 (the length of the base 32 in the Z-axis direction, which will be described with reference to FIG. 3).

[0039] Next, the flat bag 10 has, although not necessarily, crease lines L1, L2, and L3. The crease lines L1, L2, and L3 may be fold lines such as pressed creases, perforated creases, and half-cut creases. This also applies to the other creases described below.

[0040] The fold line L1 is provided parallel (or approximately parallel) to the X-axis in Fig. 2. The fold line L1 is a fold that is used to fold the bottom flap 13 and the side bottom 16 after the backing 30 is inserted into the flat bag 10. The fold line L1 makes it easy to fold the bottom flap 13 and the side bottom 16.

[0041] The fold line L2 is provided parallel (or approximately parallel) to the X-axis in Fig. 2. The fold line L2 is a fold that is used when, after the backing paper 30 is inserted into the flat bag 10, the bottom flap 13 is folded back toward the side 14 and the glued underside 15, and then the tip portion 13A of the bottom flap 13 is adhered to the side 14 and the glued underside 15. The fold line L2 makes it easy to adhere the tip portion 13A to the side 14 and the glued underside 15.

[0042] Next, the fold line L3 will be described. As described with reference to FIG. 1, the backing 30 has a taper tapered downward (described later with reference to FIG. 3). Therefore, by inserting the backing 30 into the flat bag 10 that does not have a specific structure for forming side gussets, a space is created between the taper of the backing 30 and the flat bag 10. Due to the existence of this space, the flat bag 10 can follow the shape of the backing 30 and form a side gusset 10T that is wide at the bottom and narrow at the top corresponding to the depth (Y-axis direction) of the backing 30. At this time, the fold line L3 makes it easy to form the side gusset 10T and the bottom gusset in the flat bag 10, and can also adjust the shape of the side gusset (approximately triangular in FIG. 1).

[0043] The fold line L3 extends from the upper end (or near the upper end) of the slit 16K in the Z-axis upward direction and toward the end of the flat bag 10 in the X-axis direction, and is inclined with respect to the Z-axis, in accordance with the taper formed in the backing paper 30. The inclination angle of the fold line L3 with respect to the Z-axis may be determined according to the basic design of the package 1 and / or the shape of the article 100, etc. The length of the fold line L3 may be determined corresponding to the length of the taper of the backing paper 30.

[0044] With reference to the diagram indicated by reference numeral 201 in FIG. 2, the transparent region 18 is formed by applying a transparentizing agent to and impregnating the paper material forming the flat bag 10. When the transparentizing agent is applied to the paper material forming the flat bag 10, part of the agent penetrates into the gaps between the fibers of the paper material forming the flat bag 10, and part of the agent is formed as a surface layer. The part impregnated into the gaps between the fibers of the flat bag 10 fills the gaps between the fibers of the flat bag 10 and improves the light transmittance. The part forming the surface layer smoothes the surface of the flat bag 10 and suppresses diffuse reflection of light, thereby improving the see-through property of the flat bag 10.

[0045] The area of ​​the flat bag 10 impregnated with the clarifying agent is designated by reference numeral 101 in FIG. 1 and the transparent area 18 in FIG. 2. The clarifying agent may be applied to and impregnated into both sides of the portion that will become the surface 11 (or the side 14, or the under-glue 15) of the paper material. By impregnating from both sides, the transparent agent fills the gaps between the fibers in the thickness direction of the surface 11, improving transparency. When the inner surface of the surface 11 is rougher than the front surface and only one side is impregnated with the transparent agent, the transparent agent is preferably impregnated into the inner surface. This is because the transparent agent is more easily impregnated into the rough surface (inner surface) than the glossy surface (front surface), making it possible to increase the transparency of the transparent area 18.

[0046] The flat bag 10 may have a printed layer (not shown) on the entire or part of its surface. The printed layer may have a varnish layer (not shown) formed on the upper surface thereof.

[0047] When the transparent region 18 is formed on the surface side of the flat bag 10, the transparent region 18 may be formed on the upper surface of a printed layer, or may be formed on a surface of the flat bag 10 on which no printed layer is formed. The transparent region 18 may also have a varnish layer formed on its upper surface. The printed layer may be formed on the upper surface (surface) of the transparent region 18. The design is improved by overlaying a design print (printed layer) on the transparent region 18.

[0048] The transparent region 18 is formed by impregnating the paper material forming the flat bag 10 with a transparent agent (transparent resin). The transparent resin may be, for example, a petroleum-based hydrocarbon resin, a rosin-based resin, an olefin-based resin, an acrylic resin, a polyester-based resin, a urethane-based resin, a paraffin wax, or a fluororesin, and may be used alone or in combination of two or more types, or may further contain additives. The transparent resin is applied in the form of an aqueous emulsion or an organic solvent solution. The transparent resin may be, for example, "Clariten DC" made of an alicyclic saturated hydrocarbon resin, which is a petroleum-based hydrocarbon resin, or "LG-WR Marking Agent" made by Toyo Ink Co., Ltd. The transparent region 18 is formed by appropriately adjusting the type and / or amount of transparent resin applied so as to obtain a desired transparency. The transparent region 18 may be formed by a method of impregnating the transparent resin into the flat bag 10 only in the necessary portion. The transparent region 18 may also be formed by a method of impregnating the transparent resin into the paper material forming the flat bag 10 by various printing methods (e.g., flexographic printing, inkjet printing, gravure printing, offset printing, gravure offset printing, silk screen printing).

[0049] The clarifying agent may be not only a type in which an emulsion or solution is applied and dried, but also a type which is cured by exposure to ultraviolet light or electron beams.

[0050] The transparent region 18 is, for example, a sheet of one-sided glazed bleached kraft paper with a basis weight of 50 g / m 2 ~70g / m 2 In the case of , the coating amount is 2g / m2 after drying. 2 ~15g / m 2 About 3 g / m 2 ~12g / m 2 If the amount of the clarifying agent applied is small, the transparency is poor. If the amount of the clarifying agent applied is large, the coating drying property is poor, the difference in thickness and / or hardness of the sheet between the coated and non-coated parts of the clarifying agent is large, and the suitability for processing such as bag making is also poor.

[0051] 2 again, hole 19 is formed above flat bag 10 (above the Z axis), although not limited thereto. Furthermore, mount 30 (not shown) has a hole at a position corresponding to hole 19. This allows package 1 to be displayed in a hangable manner in a drugstore or the like. The size and / or position of hole 19 may be determined taking into consideration the hanging strength, display method, etc.

[0052] A specific example of the flat bag 10 according to one embodiment of the present disclosure has been described above with reference to Fig. 2. In the example of Fig. 2, the flat bag 10 is configured so that the lower end of the flat bag 10 is an open end and the backing paper 30 is inserted from the open end. However, as described with reference to the package 2 indicated by reference numeral 102 in Fig. 1, the flat bag 10 may be configured so that the upper end of the flat bag 10 is an open end and the backing paper 30 is inserted from the open end.

[0053] (Paper) Next, the mount according to the present disclosure will be described with reference to Fig. 3 etc. First, in short, the mount according to the present disclosure has a main surface and a base that is foldably connected to the main surface and forms the bottom of the package, and the main surface has a taper that tapers toward the side where the base is located in the area on the side where the base is located. That is, the mount according to the present disclosure may have a basic configuration in which the main surface and the base form an L-shape, and even with this basic configuration, a package with a gusset that can be manufactured by a simple method can be provided.

[0054] However, in the following, a description will be given of mounts 30, 60, and 90 according to the present disclosure, which can be considered as an advanced version of a mount having a basic configuration in an L-shape.

[0055] (Paper 1) A mount 30 according to an embodiment of the present disclosure will be described with reference to Figs. 3 to 5. Fig. 3 is a development view of the mount 30 according to an embodiment of the present disclosure. As described with reference to the view indicated by reference numeral 101 in Fig. 1, the mount 30 is suitably used as a mount inserted into the flat bag 10 from the lower end of the flat bag 10.

[0056] First, referring to FIG. 3, the mount 30 is composed of a main surface portion 31 having a first connecting portion 34, a base portion 32, and a second connecting portion 33. More specifically, the mount 30 has the main surface portion 31 and a base portion 32 that is foldably connected to the main surface portion 31 and forms the bottom of the package 1. The main surface portion 31 has a taper 31T that tapers toward the side where the base portion 32 is located in a region on the side where the base portion 32 is located. Furthermore, the mount 30 has a second connecting portion 33 that extends from the base portion 32 in a direction opposite to the main surface portion 31. The second connecting portion 33 has a taper 33T that tapers toward the side where the base portion 32 is located in a region on the side where the base portion 32 is located.

[0057] 3, fold line 32LA is a fold formed between main surface portion 31 and base portion 32. Fold line 32LB is a fold formed between base portion 32 and second connection portion 33. By having fold lines 32LA and 32LB, mount 30 makes it easy to assemble mount 30 three-dimensionally by making main surface portion 31 and second connection portion 33 face or overlap each other.

[0058] The fold lines 32LA and / or fold lines 32LB may have slits. This makes it easier to cut the mount 30 at the fold lines 32LA and / or fold lines 32LB, and makes it easier to disassemble the mount 30 when disposing of the mount 30. Such innovations in the fold lines may also be adopted in the mounts 60 and 90 described below.

[0059] The mount 30 has a first connection portion 34 extending from the main surface portion 31. More specifically, the main surface portion 31 has a slit 34K1 formed in the plane of the main surface portion 31 in a convex shape facing downward in the Z-axis direction. The slit 34K1 is located between two tapers 31T. The slit 34K1 is formed by connecting two slits parallel (or approximately parallel) to the taper 31T and one slit parallel (or approximately parallel) to the X-axis that connects the ends of the two slits on the base 32 side. As a result, the first connection portion 34 extends from a region between the end portion of the main surface portion 31 on the side where the base 32 is located and the tip portion on the opposite side to the end portion toward the end portion (base 32 side). Therefore, when the mount 30 is assembled three-dimensionally, the first connection portion 34 can extend in the direction of the second connection portion 33. Furthermore, by providing the slit 34K1 between the two tapers 31T, the article 100 is arranged side by side with the taper 31T, except for a flattened portion such as the tail of the tube container. This allows the taper 31T and the side portion of the tube container to be parallel (or approximately parallel) in a front view, improving the design and commercial value of the package 1.

[0060] The mount 30 has a base portion 35 extending from the second connection portion 33. More specifically, the second connection portion 33 has a slit 35K formed in a Z-axis downward convex shape in the plane of the second connection portion 33. The slit 35K is formed by connecting two slits parallel (or approximately parallel) to the Z axis and one slit parallel (or approximately parallel) to the X axis that connects the ends of the two slits on the opposite side to the base portion 32. As a result, the base portion 35 extends from a region between the end portion of the second connection portion 33 on the side where the base portion 32 is located and the tip portion on the opposite side to the end portion to the opposite side. Therefore, when the mount 30 is assembled three-dimensionally, the base portion 35 can extend in the direction of the main surface portion 31.

[0061] A fold line 35L is formed in the plane of the second connecting portion 33 parallel (or approximately parallel) to the X-axis so as to connect both ends of the slit 35K on the base 32 side. When the base portion 35 is folded along the fold line 35L, an opening (referred to as "opening A") corresponding to the outer edge shape of the base portion 35 is exposed in the plane of the second connecting portion 33. This allows the first connecting portion 34 to be received in the opening A when the mount 30 is assembled so that the main surface portion 31 and the second connecting portion 33 face or overlap each other.

[0062] 3, the first connection portion 34 has two slits 34K2 parallel (or approximately parallel) to the X-axis direction near the end and at a corner on the side where the base portion 32 is located. The first connection portion 34 also has a fold line 34L formed from a tip of the slit 34K2 located on the inner side of the first connection portion 34 toward the base portion 32. In FIG. 3, the area surrounded by the slit 34K2 and the fold line 34L is the hook portion 34A. There are two hook portions 34A in the first connection portion 34, at the end and at a corner on the side where the base portion 32 is located.

[0063] According to the above configuration, when the mount 30 is assembled so that the main surface portion 31 and the second connecting portion 33 face or overlap each other, and then the first connecting portion 34 is received in the opening A, the slit 34K2 can be hooked onto the edge of the opening A. When the slit 34K2 is hooked onto the edge of the opening A, the first connecting portion 34 is locked onto the edge of the opening A, and the relative positional relationship between the main surface portion 31 and the second connecting portion 33 can be fixed.

[0064] Furthermore, the mount 30 may have an extension 37 extending from the main surface portion 31. The extension 37 is located above the first connection portion 34 in the Z-axis direction. More specifically, the main surface portion 31 has a slit 37K formed in the plane of the main surface portion 31 in a convex shape facing downward in the Z-axis direction. The slit 37K is formed by connecting two slits parallel (or approximately parallel) to the Z-axis and one slit parallel (or approximately parallel) to the X-axis that connects the ends of the two slits on the base 32 side. This allows the extension 37 to extend from a region between the end of the main surface portion 31 on the side where the base 32 is located and the tip end on the opposite side to the end to the end (base 32 side). Therefore, when the mount 30 is assembled three-dimensionally, the extension 37 can extend in the opposite direction to the second connection portion 33.

[0065] According to the above configuration, when a tube container is placed at a predetermined position on the backing 30 so that the tail is facing upward (upward on the Z axis) and the head, which is the cap side, is facing downward (downward on the Z axis), the backing 30 can support the tube container more stably by inserting the tail of the tube container into the slit 37K.

[0066] Next, the base 32 will be described. The base 32 has two fold lines 36L parallel (or approximately parallel) to the Z-axis direction. The fold line 36L is formed from the fold line 32LA to the fold line 32LB. The base 32 also has a slit 36K1 that is convex toward the left of the X-axis so as to connect two points that are intersections of the fold line 36L located on the left side of the X-axis with the fold line 32LA and the fold line 32LB. The slit 36K1 is formed by connecting two slits parallel (or approximately parallel) to the X-axis and one slit parallel (or approximately parallel) to the Z-axis that connects the ends of the two slits on the left side of the X-axis. As a result, the grip part 36 on the left side of the X-axis extends to the left side of the X-axis. Therefore, when the mount 30 is assembled three-dimensionally, the grip part 36 on the left side of the X-axis can extend upward in the Z-axis direction (see Figs. 4 and 5).

[0067] The base 32 also has a slit 36K2 that is convex toward the right of the X-axis, connecting two points that are the intersections of the fold line 36L on the right side of the X-axis with the fold lines 32LA and 32LB. The slit 36K2 is formed by connecting two slits that are parallel (or approximately parallel) to the X-axis and one slit that is parallel (or approximately parallel) to the Z-axis and connects the ends of the two slits on the right side of the X-axis. This allows the grip part 36 on the right side of the X-axis to extend to the right of the X-axis. When the mount 30 is assembled three-dimensionally, the grip part 36 on the right side of the X-axis can extend upward along the Z-axis (see Figs. 4 and 5).

[0068] According to the above configuration, when the gripping portion 36 is folded along the fold line 36L, an opening (referred to as "opening B") corresponding to the outer edge shape of the gripping portion 36 is exposed within the surface of the base 32. Therefore, the base 32 has a bottom surface portion 32A forming the bottom surface of the base 32, and the gripping portion 36 standing upright relative to the bottom surface portion 32A along the fold line 36L, and an opening (opening B) can be formed in the bottom surface portion 32A by the gripping portion 36 standing upright. When the mount 30 is inserted into the flat bag 10 from the tip side of the main surface portion 31 (the side opposite to the side where the base 32 is located), the mount 30 allows the user to insert his / her finger into the opening and grip the gripping portion 36. This allows the mount 30 to be easily inserted into the flat bag 10 and removed from the flat bag 10.

[0069] Fig. 4 is a diagram showing the front surface (with the main surface portion 31 facing the front side) of the mount 30 when assembled according to one embodiment of the present disclosure, as viewed from an oblique front side. Fig. 5 is a diagram showing the rear surface (with the second connection portion 33 facing the front side) of the mount 30 when assembled according to one embodiment of the present disclosure, as viewed from an oblique front side.

[0070] 4 and 5, the mount 30 is folded along the crease lines 32LA and 32LB to be assembled three-dimensionally so that the main surface portion 31 and the second connecting portion 33 face or overlap each other. At this time, the first connecting portion 34 of the main surface portion 31 extends in the direction of the second connecting portion 33, and is inserted into the opening A exposed by folding the base portion 35. At this time, as described above, the slit 34K2 of the first connecting portion 34 is hooked onto the opening edge of the opening A, so that the first connecting portion 34 is engaged with the opening edge of the opening A. This fixes the relative positional relationship between the main surface portion 31 and the second connecting portion 33.

[0071] Furthermore, when the base portion 35 and the gripping portion 36 of the backing paper 30 are both folded approximately 90 degrees, the bottom surface of the base portion 35 located below the Z axis is positioned on the two end edges of the gripping portion 36 located above the Z axis.

[0072] 1, the mount 30 can place the cap of the tube container on the upper surface of the folded base portion 35. Then, by inserting the tail portion of the cap, which is the flat sealed end side, into the slit 37K, the mount 30 can more stably support the tube container.

[0073] Furthermore, at this time, in the Z-axis direction, the upper surface of the base portion 35 may be located lower than the bottom side of the opening exposed to the main surface portion 31 by extending the first connection portion 34 in the direction of the second connection portion 33. With this configuration, a step is formed between the upper surface of the base portion 35 and the opening exposed to the main surface portion 31, making it difficult for the tube container to fall off the backing paper 30. Therefore, the backing paper 30 can support the tube container more stably.

[0074] In this way, the gripping portion 36 functions as a side surface (leg) of the base portion 35 which functions as a base on which the article 100 is placed. In addition, since the gripping portion 36 is positioned between the main surface portion 31 and the second connecting portion 33 when the backing 30 is assembled, the gripping portion 36 also plays a role in determining the positional relationship between the main surface portion 31 and the second connecting portion 33.

[0075] 4 and 5, the main surface portion 31 has a taper 31T and the second connecting portion 33 has a taper 33T so as to taper downward in the Z-axis direction. With this configuration, by inserting the backing sheet 30 from the lower end of the flat bag 10 into the flat bag 10 that does not have a specific structure for forming side gussets, a space is created between the taper of the backing sheet 30 and the flat bag 10. Due to the existence of this space, the flat bag 10 can follow the shape of the backing sheet 30 and form a substantially triangular side gusset 10T (see FIG. 1) that is wide at the bottom and narrow at the top corresponding to the depth (Y-axis direction) of the backing sheet 30. As a result, when inserted into the flat bag 10, the backing sheet 30 maintains an upright state and can form side gussets and a bottom gusset in the package 1.

[0076] The above describes the mount 30. The shape of the mount 30 can be changed as appropriate as long as it has the above-mentioned functions and fits the shape of the flat bag 10. This also applies to mounts 60 and 90 described below. For example, the mount 30 is configured as follows.

[0077] The main surface portion 31 has a non-tapered region 31R parallel to the Z axis from the taper 31T toward the end portion of the main surface portion 31 opposite the base portion 32. The non-tapered region 31R is a region that provides the maximum width in the X-axis direction of the main surface portion 31. By having the non-tapered region 31R, the main surface portion 31 stabilizes the backing paper 30 within the flat bag 10 when the backing paper 30 is inserted into the flat bag 10.

[0078] The maximum width in the X-axis direction of the main surface portion 31 is 85% to 99%, and preferably 90% to 99%, of the inner dimension S1 (see FIG. 2) of the flat bag 10. This makes it possible to make the backing paper 30 more stable inside the flat bag 10 when the backing paper 30 is inserted into the flat bag 10.

[0079] 3, S2 indicates the depth of the base 32 (length in the Z-axis direction), and S3 indicates the width of the base 32 (maximum width in the X-axis direction). In this case, S2+S3 is 90% to 99% of S1, and preferably 95% to 99%. This makes it possible to make the mount 30 more stable inside the flat bag 10 when the mount 30 is inserted into the flat bag 10.

[0080] In this way, the mount 30 may be designed so that the main surface portion 31 has a maximum width corresponding to the width of the open end of the flat bag 10, and the base portion 32 has a maximum width corresponding to the width of the open end of the flat bag 10. This allows the mount 30 to be more stably accommodated within the flat bag 10. In this way, the mount 30 may be designed to be flexible. The same applies to the mounts 60 and 90 described below.

[0081] The tapers 31T and 33T are not limited to being linear as shown in Fig. 3, but may have a curved surface, or may have a notched portion in the middle of the taper. This also applies to the mount 60 and mount 90 described later.

[0082] (Paper 2) Next, a mount 60 according to another embodiment of the present disclosure will be described with reference to Fig. 6 to Fig. 8. Fig. 6 is a development view of the mount 60 according to an embodiment of the present disclosure. As described with reference to the view indicated by reference numeral 102 in Fig. 1, the mount 60 is suitably used as a mount inserted into the flat bag 10 from the upper end of the flat bag 10.

[0083] First, referring to FIG. 6, the mount 60 is composed of a main surface portion 61 having a first connecting portion 64, a base portion 62, and a second connecting portion 63. More specifically, the mount 60 has the main surface portion 61 and a base portion 62 that is foldably connected to the main surface portion 61 and forms the bottom of the package 1. The main surface portion 61 has a taper 61T that tapers toward the side where the base portion 62 is located in a region on the side where the base portion 62 is located. Furthermore, the mount 60 has a second connecting portion 63 that extends from the base portion 62 in a direction opposite to the main surface portion 61. The second connecting portion 63 has a taper 63T that tapers toward the side where the base portion 62 is located in a region on the side where the base portion 62 is located.

[0084] 6, fold line 62LA is a fold formed between main surface portion 61 and base portion 62. Fold line 62LB is a fold formed between base portion 62 and second connection portion 63. By having fold lines 62LA and 62LB, backing sheet 60 makes it easy to assemble backing sheet 60 three-dimensionally by making main surface portion 61 and second connection portion 63 face or overlap each other.

[0085] The mount 60 has a first connection portion 64 extending from the main surface portion 61. More specifically, the main surface portion 61 has a slit 64K formed in the plane of the main surface portion 61 in a Z-axis downward convex shape. The slit 64K is located between two tapers 61T. The slit 64K is formed by connecting two slits parallel (or approximately parallel) to the taper 61T and one slit parallel (or approximately parallel) to the X-axis that connects the ends of the two slits on the base 62 side. As a result, the first connection portion 64 extends from a region between the end portion of the main surface portion 61 on the side where the base 62 is located and the tip portion on the opposite side to the end portion toward the end portion (base 62 side). Therefore, when the mount 60 is assembled three-dimensionally, the first connection portion 64 can extend in the direction of the second connection portion 63.

[0086] The main surface portion 61 has a hole 69 at a position that corresponds to the hole 19 (not shown) of the flat bag 10 when the backing 60 is inserted into the flat bag 10, although this is not limited thereto. This allows the package 2 to be displayed in a manner that allows it to be hung in a drugstore or the like. Although no hole similar to the hole 69 is formed in the main surface portion 31 described with reference to Fig. 3, the main surface portion 31 may naturally have a hole similar to the hole 69.

[0087] The mount 60 has a base portion 65 extending from the second connection portion 63. More specifically, the second connection portion 63 has a slit 65K formed in a Z-axis downward convex shape in the plane of the second connection portion 63. The slit 65K is formed by connecting two slits parallel (or approximately parallel) to the Z axis and one slit parallel (or approximately parallel) to the X axis that connects the ends of the two slits on the opposite side to the base portion 62. As a result, the base portion 65 extends from a region between the end portion of the second connection portion 63 on the side where the base portion 62 is located and the tip portion on the opposite side to the end portion to the opposite side. Therefore, when the mount 60 is assembled three-dimensionally, the base portion 65 can extend in the direction of the main surface portion 61.

[0088] A fold line 65L is formed in the plane of the second connecting portion 63 parallel (or approximately parallel) to the X-axis so as to connect both ends of the slit 65K on the side of the base portion 62. When the base portion 65 is folded along the fold line 65L, an opening corresponding to the outer edge shape of the base portion 65 is exposed in the plane of the second connecting portion 63.

[0089] A slit 66 extending in the X-axis direction is formed in the surface of the second connecting portion 63. The width of the slit 66 in the length direction (X-axis direction) is equal to or less than the maximum width (width in the X-axis direction) of the first connecting portion 64. With this configuration, when the mount 60 is assembled three-dimensionally with the main surface portion 61 and the second connecting portion 63 facing or overlapping each other, the first connecting portion 64 and the slit 66 can be connected by inserting the tapered end of the first connecting portion 64 into the slit 66. Furthermore, the relative positional relationship between the main surface portion 61 and the base portion 62 can be changed within a predetermined range. This configuration (sliding structure) will be described in more detail with reference to FIGS. 7 and 8.

[0090] Fig. 7 is a diagram showing an example of the shape of the backing sheet 60 when insertion of the backing sheet 60 into the flat bag 10 begins. Fig. 8 is a diagram showing an example of the shape of the backing sheet 60 when insertion of the backing sheet 60 into the flat bag 10 is completed.

[0091] 7 shows an example of the shape of the backing 60 when the base 62 is inserted into the upper opening end (not shown) of the flat bag 10. By keeping the interior angle (θ1) between the main surface portion 61 and the base 62 at an obtuse angle, the interior angle between the second connecting portion 63 of the backing 60 and the base 62 to be inserted into the opening end of the flat bag 10 becomes an acute angle, making insertion easier. When inserting the backing 60 into the opening end of the flat bag 10, the article 100 can be placed on the first connecting portion 64, and the backing 60 and the article 100 can be inserted into the flat bag 10 at the same time.

[0092] Fig. 8 shows an example of the shape of the backing 60 when the backing 60 has been completely inserted into the flat bag 10 or at the final stage of insertion. When the backing 60 is inserted into the flat bag 10 from the state shown in Fig. 7, a force is applied from the flat bag 10 to the base 62 in a direction that reduces θ1 due to friction between the base 62 and the flat bag 10. Then, the base 62 comes into contact with the bottom flap 13 (not shown) of the flat bag 10, so that the interior angle (θ2) between the main surface portion 61 and the base 62 becomes even smaller. In Fig. 8, θ2 is an acute angle.

[0093] At this time, the width in the length direction (X-axis direction) of the slit 66 formed in the second connecting portion 63 is preferably equal to or less than the maximum width in the X-axis direction of the first connecting portion 64. This sets a limit to the amount by which the end of the first connecting portion 64 is inserted into the slit 66. Then, θ2 becomes an acute angle, in other words, the base 62 rises relative to the main surface portion 61, and the end of the first connecting portion 64 is inserted into the slit 66 to the maximum extent, thereby fixing the relative positional relationship between the main surface portion 61 and the base 62. This makes it possible to stabilize the shape of the backing 60.

[0094] In addition, when the base 62 rises up relative to the main surface 61, the side gusset portion spreads, and the main surface 61 and the base 62 are fixed together to form a side gusset that is wider on the lower side toward the base 62 and narrower on the upper side.

[0095] According to the above configuration, it becomes easy to insert the backing sheet 60 into the open end of the flat bag 10 from the base 62 side, and it is also easy to realize a state in which the backing sheet 60 can stand up inside the flat bag 10. As a result, the backing sheet 60 can maintain an upright state when inserted into the flat bag 10, and can form side and bottom gussets in the package 2.

[0096] Here, by extending the first connecting portion 64 in the direction of the second connecting portion 63 and inserting it into the slit 66, an opening corresponding to the outer edge shape of the first connecting portion 64 is exposed in the main surface portion 61. This allows the mount 60 to support the article 100 (not shown) by placing it in the opening. At this time, the base portion 65 is folded to a position parallel (or approximately parallel) to the base 62. This allows the bottom portion of the article 100 (for example, if the article 100 is a cap, then the top surface of the cap) to be placed on the top surface of the base portion 65, and the mount 60 can support the article 100 more stably.

[0097] In addition, the backing 60 is not limited to a configuration in which the main surface portion 61 has the first connection portion 64 and the second connection portion 63 has the slit 66, but may be flexibly designed, such as being realized by a configuration in which the main surface portion 61 has the slit 66 and the second connection portion 63 has the first connection portion 64.

[0098] In the above description, the first connecting portion 34 is tapered toward the tip. However, the first connecting portion 64 may be formed in a rectangular shape, with a stopper (such as a notch) provided on the side edge of the first connecting portion 64 and the stopper engaged with the slit 66. This configuration (sliding structure) also makes it possible to fix the relative positional relationship between the main surface portion 61 and the base portion 62 and stabilize the shape of the mount 60.

[0099] In this manner, the mount 60 according to the present disclosure may be modified in various ways and may be realized with a configuration obtained by appropriately combining the disclosed configurations.

[0100] (Paper 3) Next, a mount according to another embodiment of the present disclosure will be described with reference to Fig. 9 and Fig. 10. Fig. 9 is a development view of a mount 90 according to one embodiment of the present disclosure. The mount 90 is suitably used as a mount for supporting a cylindrical article such as lipstick.

[0101] 9, the mount 90 is composed of a main surface portion 91, a base portion 92, and a sub-surface portion 93. More specifically, the mount 90 has the main surface portion 91 and a base portion 92 that is foldably connected to the main surface portion 91 and forms the bottom of the package 1. The main surface portion 91 has a taper 91T in the region on the side where the base portion 92 is located that tapers toward the side where the base portion 92 is located.

[0102] Furthermore, the mount 90 has a secondary surface 93 extending from the base 92 in the direction opposite to the primary surface 91. The secondary surface 93 has a taper 93T in the region on the side where the base 92 is located that tapers toward the side where the base 92 is located.

[0103] Here, the base 92 indicates the area sandwiched between the fold line 91L and the fold line 93L, which will be described later. The area sandwiched between the fold line 92LA and the fold line 91L and the area sandwiched between the fold line 92LB and the fold line 93L are not areas that function as the bottom surface of the mount 90 when the mount 90 is assembled. However, referring to the development view of the mount 90 shown in FIG. 9, the area sandwiched between the fold line 91L and the fold line 93L corresponds to the area sandwiched between the main surface portion 91 and the secondary surface portion 93. In addition, the area sandwiched between the fold line 92LA and the fold line 91L and the area sandwiched between the fold line 92LB and the fold line 93L are located at the bottom of the mount 90 when the mount 90 is assembled. In light of the above, the base 92 indicates the area sandwiched between the fold line 91L and the fold line 93L.

[0104] The distance in the Z-axis direction between fold line 92LA and fold line 91L, and the distance in the Z-axis direction between fold line 92LB and fold line 93L may be determined according to the basic design of backing sheet 90 and / or the shape of article 100, etc.

[0105] 9, fold lines 92LA and 92LB are folds that are parallel (or approximately parallel) to the X-axis direction and are formed in base 92. By having fold lines 92LA and 92LB, mount 90 makes it easy to assemble mount 90 three-dimensionally by making main surface 91 and sub-surface 93 face each other or overlap each other.

[0106] The fold line 91L is a fold formed between the main surface portion 91 and the base portion 92. The fold line 93L is a fold formed between the base portion 92 and the secondary surface portion 93. The fold line 91L and the fold line 93L are folds parallel (or approximately parallel) to the X-axis. By having the fold line 91L and the fold line 93L, the backing sheet 90 can create a state in which the main surface portion 91 and the secondary surface portion 93 abut at the fold line 91L and the fold line 93L when the backing sheet 90 is assembled three-dimensionally.

[0107] The main surface portion 91 has a rectangular item placement portion 94 with its longitudinal direction in the Z-axis direction within the plane of the main surface portion 91. The item placement portion 94 is formed in a shape corresponding to the lipstick that the mount 90 is to support.

[0108] 9, the main surface portion 91 has a semicircular protrusion 94A that protrudes from the upper end toward the lower end side in the Z axis direction of the item placement portion 94. The main surface portion 91 also has a semicircular protrusion 94B that protrudes from the lower end toward the upper end side in the Z axis direction of the item placement portion 94. The main surface portion 91 has a fold line 94L that extends along the lower end edge in the Z axis direction of the item placement portion 94, and the protrusion 94B can be folded via the fold line 94L.

[0109] According to the above configuration, for example, the user can fit the lipstick into the item placement section 94 in the following manner. It is assumed that the bottom surface of the lipstick is recessed.

[0110] First, protrusion 94A is inserted into the recess on the bottom surface of the lipstick. Next, protrusion 94B is folded approximately 90 degrees along fold line 94L, and the top surface of the lipstick is placed on the folded protrusion 94B. This allows the lipstick to be fitted into item placement section 94, with the top and bottom surfaces of the lipstick sandwiched between protrusions 94A and 94B, and the lipstick can be supported on mount 90.

[0111] Next, the main surface portion 91 has a slit 96KA formed in a substantially semicircular shape convex downward along the Z axis within the plane of the main surface portion 91. The slit 96KA is located below the article placement portion 94 in the Z axis direction. A fold line 96LA is formed in the plane of the main surface portion 91 parallel (or substantially parallel) to the X axis so as to connect both ends of the slit 96KA. The area sandwiched between the slit 96KA and the fold line 96LA is the protrusion portion 96A. With this configuration, the protrusion portion 96A can be folded via the fold line 96LA.

[0112] Furthermore, the main surface portion 91 has a slit 97KA formed in a generally semicircular shape convex downward along the Z axis within the plane of the main surface portion 91. The slit 97KA is formed with two starting points on the fold line 91L. The area between the slit 97KA and the fold line 91L is the protrusion 97A. With this configuration, the protrusion 97A can be folded via the fold line 91L.

[0113] The main surface portion 91 has holes 99 at positions corresponding to the holes 19 of the flat bag 10 when the mount 90 is inserted into the flat bag 10, although this is not limited thereto. This allows the package to be displayed in a hanging manner in a drug store or the like.

[0114] Continuing to refer to Fig. 9, the secondary surface portion 93 will be described. For ease of explanation, the hole 96B, the hole 97B, and the opening 95 will be described in this order.

[0115] The secondary surface portion 93 has a hole 96B near the upper end in the Z-axis direction of the secondary surface portion 93. The hole 96B has an outer edge cut out in two places by a cut 96KB that passes through the center (or approximately the center) of the hole 96B and is parallel (or approximately parallel) to the X-axis direction.

[0116] Further, the secondary surface portion 93 has a hole 97B on the fold line 93L. The hole 97B has two notches at the outer edge thereof by a slit 97KB that passes through the center (or approximately the center) of the hole 97B and is formed on the fold line 93L.

[0117] Mount 90 has protrusions 96A, 97A, holes 96B, and holes 97B, thereby providing the following effects, which will be described with reference to Fig. 10. Fig. 10 is a view of mount 90 according to one embodiment of the present disclosure, viewed obliquely from the front on the main surface portion 91 side when the mount 90 is assembled.

[0118] Specifically, as described above, the mount 90 has the fold lines 91L and 93L, so that the mount 90 can be assembled three-dimensionally with the main surface portion 91 and the sub-surface portion 93 in contact with each other at the fold lines 91L and 93L. At this time, the main surface portion 91 and the sub-surface portion 93 can be easily maintained in contact with each other by bending the protrusion 96A and inserting it into the hole 96B and the slit 96KB, and / or bending the protrusion 97A and inserting it into the hole 97B and the slit 97KB.

[0119] Therefore, it is preferable that the width (length in the X-axis direction) of the protrusion 96A is approximately the same as or slightly smaller than the combined width (length in the X-axis direction) of the hole 96B and the slit 96KB. It is also preferable that the width (length in the X-axis direction) of the protrusion 97A is approximately the same as or slightly smaller than the combined width (length in the X-axis direction) of the hole 97B and the slit 97KB. This makes it easier to maintain the state in which the main surface portion 91 and the sub-surface portion 93 are in contact. The shape or size of each hole, slit, and protrusion is designed taking into consideration the ease of insertion, the strength with which the contact state is maintained, and the like.

[0120] 9, the secondary surface portion 93 has a substantially rectangular opening 95, the longitudinal direction of which is in the Z-axis direction, between the holes 96B and 97B. When the mount 90 is assembled three-dimensionally, the opening 95 is formed in a position and shape corresponding to the item placement portion 94.

[0121] A plurality of slits 95K are formed at predetermined intervals in the X-axis direction and the Z-axis direction across multiple layers around the opening 95 so as to surround the outer edge of the opening 95. This allows the slit region 95A included in the slit 95K in the outermost layer from the outer edge of the opening 95 to move in the Y-axis direction. At this time, the slit region 95A can move in the Y-axis direction to a position farther from the secondary surface portion 93 the closer it is to the opening 95.

[0122] According to this configuration, when the backing 90 is assembled so that the main surface portion 91 and the sub-surface portion 93 abut against each other, the opening 95 is formed in a position and shape that corresponds to the item placement portion 94. Therefore, the slit region 95A can gently and stably support the lipstick fitted in the item placement portion 94 like a cushion. Supporting the lipstick in this manner enhances the design of the package 1 and also improves the appeal of the package 1 as a package.

[0123] 10, the main surface portion 91 has a taper 91T and the secondary surface portion 93 has a taper 93T so as to taper downward in the Z-axis direction. With this configuration, by inserting the backing sheet 90 from the lower end of the flat bag 10 into the flat bag 10 that does not have a specific structure for forming side gussets, a space is created between the taper of the backing sheet 90 and the flat bag 10. Due to the existence of this space, the flat bag 10 can follow the shape of the backing sheet 90 while securing a storage space for the article 100, and forms a side gusset 10T (not shown) that is wide at the bottom and narrow at the top corresponding to the depth (Y-axis direction) of the backing sheet 90. As a result, when inserted into the flat bag 10, the backing sheet 90 maintains an upright state and can form side gussets and a bottom gusset in the package.

[0124] In addition, the backing paper 90 is not limited to a configuration in which the main surface portion 91 has an item placement portion 94 and the secondary surface portion 93 has an opening 95, but may be flexibly designed, such as being realized by a configuration in which the main surface portion 91 has an opening 95 and the secondary surface portion 93 has an item placement portion 94.

[0125] In this manner, the mount 90 according to the present disclosure may be modified in various ways and may be realized with a configuration obtained by appropriately combining the disclosed configurations.

[0126] The above describes a package according to an embodiment of the present disclosure, including the mount 30, the mount 60, and the mount 90. According to the above configuration, the package according to the present disclosure can provide a package having a gusset that can be manufactured by a simple method.

[0127] In the above description, each package according to the present disclosure contains only one article 100. However, the mount according to the present disclosure can support multiple articles 100 by providing the above-mentioned functions.

[0128] The packaging disclosed herein can use flat paper bags and backing sheets and can replace the resin packaging that has been used traditionally. This is in line with the sustainable circular economy called for by the global trend of SDGs (Sustainable Development Goals) and can make a significant contribution to reducing plastic waste.

[0129] (flowchart) Next, a method for manufacturing a package according to the present disclosure will be described with reference to Fig. 11. Fig. 11 is a flow chart for explaining a method for manufacturing a package according to the present disclosure. In the following, a mount 30 is used as the mount according to the present disclosure. However, it is of course possible to substitute mount 60 or mount 90 for mount 30.

[0130] First, a flat bag 10 having an open end and no special structure for forming a side gusset is prepared (S10).

[0131] Next, a backing sheet 30 is prepared, which has a main surface portion 31 and a base portion 32 that is foldably connected to the main surface portion 31, and the main surface portion 31 has a taper 31T at the end portion on the side where the base portion 32 is located, where the main surface portion 31 tapers toward the base portion 32 (S20).

[0132] Next, the article 100 is placed in an article placement section provided at a position corresponding to the area where the taper 31T is formed in the main surface portion 31 (S30). With reference to Figs. 4 and 5, the article placement section corresponds to the area where the article 100 is placed. Specifically, the article placement section is an area where the article 100 is placed between the upper surface of the folded base portion 35 on the Z-axis upper side on which the upper surface of the cap of the tube container is placed and the slit 37K into which the tail portion of the cap of the tube container, which is the flat sealed end side, is inserted. As described above, the article 100 may be placed by fixing with an adhesive or double-sided tape, or by covering with a shrink film (shrink sleeve) adhered to a mount.

[0133] Then, the mount 30 on which the article 100 is placed is inserted into the flat bag 10 from the open end of the flat bag 10, and the base 32 bent relative to the main surface 31 forms the bottom of the package 1 (S40).

[0134] Through the above steps S10 to S40, the package 1 according to the present disclosure can be manufactured.

[0135] (summary) A packaging body according to aspect 1 of the present disclosure is a packaging body for packaging an article, comprising: the article; a flat bag that does not have a special structure for forming a side gusset alone; and a backing sheet that supports the article, wherein the backing sheet has a main surface portion and a base portion that is foldably connected to the main surface portion and forms the bottom of the packaging body, and the main surface portion has a taper in the region on the side where the base is located that narrows toward the side where the base is located.

[0136] According to the above-mentioned configuration, the main surface of the backing supporting the article has a taper that tapers toward the base that forms the bottom of the package, in the region on the side where the base is located. Therefore, by inserting the backing into a flat bag that does not have a specific structure for forming a side gusset (hereinafter, a flat bag without a gusset), a space is created between the taper of the main surface and the flat bag. This space allows the flat bag to follow the shape of the backing, and it is possible to form a side surface (side gusset) that corresponds to the depth of the base. Therefore, the backing can be maintained in an upright state inside the flat bag, and a bottom gusset can be formed.

[0137] Therefore, a package having a gusset can be manufactured by the simple method of inserting a backing sheet having the base into a flat bag without a gusset.

[0138] A packaging body according to aspect 2 of the present disclosure is the same as in aspect 1, except that the backing has a secondary surface extending from the base, and the secondary surface has a taper in the area on the side on which the base is located that narrows toward the side on which the base is located.

[0139] According to the above-mentioned configuration, a double structure can be formed by the main surface portion and the sub-surface portion, and an article can be stably supported.

[0140] A packaging body according to aspect 3 of the present disclosure is such that, in aspect 1, the backing has a first connection portion extending from the main surface portion and a second connection portion extending from the base portion, the first connection portion extending toward the end portion from a region between an end portion of the main surface portion on the side where the base portion is located and a tip portion on the opposite side, and the second connection portion has a slit for receiving the first connection portion.

[0141] When inserting the backing paper into the open end of the flat bag from the side where the base is located, the base may get caught on the open end or friction between the base and the flat bag may make it difficult to insert the backing paper into the flat bag.

[0142] According to the above configuration, by inserting the tapered end of the first connection part into the slit of the second connection part, the first connection part and the second connection part can be connected, and the relative positional relationship between the main surface part and the base part can be changed within a predetermined range. Therefore, when inserting the base part into the open end of the flat bag, the interior angle between the main surface part and the base part can be kept at an obtuse angle, in other words, the base part can be maintained in a state where it does not stand upright relative to the main surface part, making the insertion easier.

[0143] In the final stage of insertion, the base abuts against the bottom of the flat bag, thereby reducing the interior angle between the main surface and the base, in other words, the base rises. Since the width of the slit in the longitudinal direction of the second connection part is equal to or less than the maximum width of the first connection part, there is a limit to the amount that the end of the first connection part can be inserted into the slit. As the base rises and the end of the first connection part is inserted into the slit to the maximum extent, the relative positional relationship between the main surface and the base is fixed. This makes it possible to stabilize the shape of the backing paper.

[0144] In this manner, the above-described configuration makes it possible to easily insert the mount into the open end of the flat bag from the base side, and also makes it easy to realize a state in which the mount can stand up inside the flat bag.

[0145] A packaging body according to aspect 4 of the present disclosure is a packaging body according to aspect 1, wherein the base has a bottom surface portion that forms the bottom surface of the base and a handle portion that stands upright relative to the bottom surface portion, and an opening is formed in the bottom surface portion by the handle portion standing upright.

[0146] According to the above configuration, when inserting the backing paper into the flat bag from the tip side of the main surface (the side opposite to the side where the base is located), the user can insert their finger into the opening and grasp the gripping portion, making it easy to insert the backing paper into the flat bag.

[0147] The set of packaging bodies according to aspect 5 of the present disclosure includes a flat bag that does not have a special structure for forming a side gusset alone, and a backing sheet that supports the article to be packaged, the backing sheet having a main surface and a base that is foldably connected to the main surface, the flat bag having an opening end into which the backing sheet is inserted, the main surface having a tip portion having a maximum width corresponding to the width of the opening end, and an end portion on the side where the base is located, and a taper that narrows from the tip portion toward the end portion in the area on the end portion side.

[0148] According to the above configuration, it is possible to achieve the same effects as the package according to the first aspect of the present disclosure.

[0149] A manufacturing method for a packaging body according to aspect 5 of the present disclosure is a manufacturing method for a packaging body in which an article is packaged, and includes the steps of: preparing a flat bag having an opening end and no special structure for forming a side gusset alone; preparing a backing having a main surface and a base that is foldably connected to the main surface, the main surface having a taper that tapers toward the base at an end on the side on which the base is located; placing an article in an article placement section provided at a position corresponding to the area of ​​the main surface where the taper is formed; and inserting the backing with the article placed on it into the flat bag from the opening end, and forming a bottom of the packaging body with the base bent toward the main surface.

[0150] According to the above-mentioned configuration, the package according to the first aspect of the present disclosure can be produced.

[0151] The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. The technical scope of the present disclosure also includes embodiments obtained by appropriately combining the disclosed technical means. Furthermore, new technical features can be formed by combining the disclosed technical means. [Explanation of symbols]
