Description

[Technical Field]

[0001] The present invention relates to a packaging box and a packaging body. [Background technology]

[0002] Packaging boxes containing packaged items such as containers filled with cosmetics, medicines, etc. may be subjected to vibrations and shocks during transportation, which can cause the packaged items inside the packaging box to rotate or be damaged. In particular, measures are taken to fix the packaged items contained in the packaging box, from the perspective of preventing scratches or damage due to contact between the packaged items and the packaging box. Packaging boxes described in Patent Documents 1 to 4 have been proposed as such packaging boxes.

[0003] The packaging box described in Patent Document 1 includes a flat plate portion arranged to cover the top surface of the contents in the main box, and a face plate portion extending from the flat plate portion and having a central hole through which the top of the contents is inserted, and is equipped with a content fixing device in which the flat plate portion and the face plate portion are folded toward each other. The content fixing device is formed to be approximately the same shape and size as the opening of the main box, and the hole in the face plate is formed as an ellipse whose major axis extends vertically from the fold line side of the flat plate portion and the face plate portion toward the edge of the face plate. When the content fixing device is attached to the contents contained in the main box, the flat plate portion presses down on the top of the contents and locks the contents by hooking onto the contents inserted into the hole in the face plate portion.

[0004] The packaged cosmetics described in Patent Document 2 include a clear case with an opening on the back side, a cosmetic storage container to be housed in the clear case, and a fixing film attached to the back side of the cosmetic storage container. The fixing film has a surface adhesive layer formed on its surface and a notch formed in part of the film body to form a tongue, and when the fixing film is attached to the back side of the clear case via the surface adhesive layer of the film body, the tongue is attached to the back side of the cosmetic storage container via the opening, thereby preventing the cosmetic storage container from rotating.

[0005] The packaging box described in Patent Document 3 has front and rear wall portions as wall portions surrounding the periphery of a container for contents, a window hole formed in the front wall portion, fold-out pieces that are folded inward from both sides of the window hole and pressed against the container, and a fixing member that is inserted between the fold-out pieces and the rear wall portion and adhered to the container, so that the container can be stored in a state where it can be seen from the outside through the window hole. The fold-out pieces press the fixing member adhered to the container, preventing the container from rotating.

[0006] The packaging box described in Patent Document 4 includes a product packaging box body and a separate retaining plate, which has a horizontal portion that surrounds the narrowed portion of the product body and an extending portion formed integrally with the horizontal portion. The packaging box has means for restricting movement of the product body in the front-to-back and left-to-right directions within the product packaging box body, and means for restricting movement of the product body in the up-and-down direction within the product packaging box body. The horizontal portion in Patent Document 4 can separate the surrounding portion into two, and the extending portion is formed by extending from one end side of each of the two separated portions of the horizontal portion and has a joining portion for connecting the two portions that were separated by the horizontal portion.

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-8213 [Patent Document 2] Japanese Patent Application Laid-Open No. 2006-240647 [Patent Document 3] Japanese Patent Application Laid-Open No. 2011-46429 [Patent Document 4] Japanese Patent Publication No. 2021-28236 Summary of the Invention [Problem to be solved by the invention]

[0008] The packaging boxes disclosed in Patent Documents 1 to 3 employ means for fixing the packaged items and restricting their movement within the packaging box. However, when such fixing means are employed, it is not possible to sufficiently prevent contact between the inner surface of the packaging box and the packaged items, and contact between the fixing means and the surface of the packaged items can cause scratches on the surface, which can damage the appearance of the product. Furthermore, the packaging box disclosed in Patent Document 4 has an enclosing part that can be separated into two parts that easily open, making it difficult to attach the enclosing part to the product body.

[0009] The present invention relates to providing a packaging box and a package that suppresses contact between the packaged item and the packaging box, suppresses the occurrence of scratches on the surface of the packaged item, and provides excellent workability when placing the packaged item in the packaging box. [Means for solving the problem]

In one embodiment, the packaging box is preferably provided with a spacer that is arranged to surround the packaged item and maintains a gap between the inner surface of the box body and the packaged item. In one embodiment, the spacer is preferably formed from a sheet material that is integrated with the box body or separate from the box body, and has a holding body portion and a holding piece portion that partially surround the packaged item. In one embodiment, the holding body portion preferably has a missing portion in which a part of the annular shape is missing. In one embodiment, the holding piece portion is preferably capable of closing the notched portion in an openable manner. In one embodiment, in the packaging box, when in a closed state, the entire periphery of the packaged item is preferably surrounded by the holding main body portion and the holding piece portion.

[0011] The present invention also relates to a package comprising an article to be packaged having a cylindrical outer periphery and a packaging box. In one embodiment, the packaging box preferably comprises a box body that accommodates the packaged item, and a spacer that is arranged to surround the packaged item and maintain a gap between the inner surface of the box body and the packaged item. In one embodiment, the spacer is preferably formed from a sheet material that is integrated with the box body or separate from the box body, and has a holding body portion and a holding piece portion that partially surround the packaged item. In one embodiment, the holding body portion preferably has a missing portion in which a part of the annular shape is missing. In one embodiment, the holding piece portion is preferably capable of closing the notched portion in an openable manner. In one embodiment, in the package, when in a closed state, the entire circumference of the packaged item is preferably surrounded by the holding body portion and the holding piece portion. [Effects of the Invention]

[Figure 6]6(a) and (b) are explanatory views showing another embodiment of the spacer according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0014] The packaging of the present invention will be described below based on its preferred embodiments with reference to the drawings. Figure 1 shows one embodiment of the packaging of the present invention. The description of the packaging described below can be applied to the packaging box of the present invention as appropriate. The packaging body 1 of this embodiment includes a packaged item 3 having a cylindrical outer periphery and a packaging box 10. The packaging box 10 of this embodiment includes a box body 10a that accommodates the packaged item 3, and a spacer 2 that maintains a gap R between the packaged item 3 and the inner surface of the box body 10a.

[0015] The box body 10a has a hollow three-dimensional shape. As shown in Fig. 1, the box body 10a of this embodiment has a hollow hexahedron shape. The three-dimensional shape of the box body 10a is not particularly limited, and may be a cylindrical shape such as a cylinder, triangular prism, or pentagonal prism, a pyramidal shape such as a cone, triangular pyramid, or quadrangular pyramid, or a polyhedral shape such as an octahedron or dodecahedron. The box body 10a of this embodiment is configured to include a cylindrical peripheral wall portion 14, a bottom surface portion 12, and a top surface portion 13 (see FIG. 1). The peripheral wall portion 14 stands upright from the periphery of the bottom surface portion 12. The bottom surface portion 12 closes one opening of the peripheral wall portion 14. The top surface portion 13 closes the other opening of the peripheral wall portion 14 in an openable and closable manner.

[0016] The box body 10a has an internal storage space V for storing the packaged item 3 (see FIG. 1). The storage space V is mainly formed by the internal space of the cylindrical structure of the peripheral wall portion 14, and is a space defined by the peripheral wall portion 14, the bottom surface portion 12, and the top surface portion 13. In this embodiment, the peripheral wall portion 14 has a rectangular prism shape in which the horizontal cross section of the peripheral wall portion 14 is substantially square. More specifically, the peripheral wall portion 14 is formed by a pair of opposing plates 11a, 11b and a pair of side plates 11c, 11d arranged to surround the peripheral wall portion 14 on all four sides. The pair of opposing plates 11a, 11b face each other, and the pair of side plates 11c, 11d face each other between the opposing plates 11a, 11b. This gives the peripheral wall portion 14 a rectangular tubular shape. The pair of opposing plates 11a, 11b have the same shape and size, and the pair of side plates 11c, 11d also have the same shape and size. The opposing plates 11a, 11b and the side plates 11c, 11d have the same height.

[0017] For ease of explanation, of the pair of opposing plates 11a, 11b, the one to which the main flap 13b (described later) is connected will be referred to as the "rear opposing plate 11b," and the other to which the main flap 13b is not connected will be referred to as the "front opposing plate 11a." In the circumferential direction of the peripheral wall portion 14, the front opposing plate 11a is located between the pair of side plates 11c, 11d and adjacent to these side plates 11c, 11d. In the circumferential direction of the peripheral wall portion 14, the rear opposing plate 11b is located between the pair of side plates 11c, 11d and adjacent to these opposing plates 11a, 11b.

[0018] The packaging body 1 of this embodiment can stand on its own by placing the bottom surface 12 of the box body 10a on a horizontal surface. In this free-standing state, the height direction Z of the packaging body 1 coincides with the vertical direction. That is, the bottom surface 12 of the box body 10a faces downward, and the top surface 13 opposite the bottom surface 12 faces upward. Unless otherwise specified, the following description of the packaging body 1 of this embodiment will be given assuming that the box body 10a is in a free-standing state. The packaging body 1 (box body 10a) of this embodiment has a width direction Y along the width of the opposing plates 11a and 11b, a depth direction X perpendicular to the width direction Y, and a height direction Z perpendicular to the width direction Y and the depth direction X. The depth direction X is the direction along the width of the side plates 11c and 11d.

[0019] The upper surface portion 13 includes side flaps 13c and 13d connected to the upper ends of the pair of side panels 11c and 11d via fold lines b1 and b2, respectively, and a main flap 13b connected to the upper end of the rear opposing panel 11b via fold line b3 (see Figure 1). The pair of side flaps 13c, 13d are rotatable about fold lines b1, b2 that form the upper edges of the pair of side panels 11c, 11d. The main flap 13b is rotatable about fold line b3 that forms the upper edge of the rear facing panel 11b. The top surface portion 13 opens and closes the opening at the upper end of the peripheral wall portion 14 by rotating the pair of side flaps 13c, 13d and the main flap 13b.

[0020] In the box body 10a, the pair of side flaps 13c, 13d are folded inward and the main flap 13b is folded over them to form the top surface 13. With this configuration, the top surface 13 closes the upper opening of the peripheral wall 14 by folding inward the pair of side flaps 13c, 13d and the main flap 13b. In the packaging box 10, the "inside" refers to the inside side of the box body 10a (the storage space V side), and the "outside" refers to the outside side of the box body 10a. An insertion flap 13e extends from the main flap 13b on the opposite side of the fold line b3 that is connected to the main flap 13b. When the opening at the upper end of the peripheral wall 14 is closed with the main flap 13b, the insertion flap 13e is inserted between the front opposing plate 11a and the side flaps 13c and 13d, thereby fixing the main flap 13b so as to close the opening.

[0021] The packaged item 3 of this embodiment is a cylindrical container 30 (hereinafter simply referred to as "container 30") that contains a liquid or other content. This container 30 has a container body 32 with a cylindrical outer periphery and a cap 4 that closes the opening of the container body 32. The container body 32 of this embodiment has a body portion 33 with a top surface and a bottom surface, and a neck portion 34 with an opening for dispensing the content (see FIG. 1). The container 30 is housed in the box body 10a in a self-standing state, with the bottom of the body portion 33 resting on the inner surface of the bottom surface portion 12 of the box body 10a. In this state, the height direction of the container 30 (packaged item 3) coincides with the vertical direction.

[0022] The packaged item 3 may be something other than the container 30, such as a display case with a cylindrical outer periphery. The display case is made of a transparent synthetic resin molded body or a combination of sheets, and allows the interior to be seen.

[0023] The neck portion 34 is a cylindrical portion that protrudes upward from the top surface of the body portion 33 and has an internal flow path for the contents of the container 30 to flow out, with openings at both ends in the central axis direction. One of the openings in the central axis direction of the neck portion 34 is the opening that allows the contents to flow out. The interior of the neck portion 34 communicates with the interior of the body portion 33 via the other opening of the neck portion 34. The body portion 33 forms the main part of the container body 32 and has a cylindrical peripheral wall portion 33a that hangs down from the entire lower periphery of the top surface, and a bottom portion 33b located at the lower end of the peripheral wall portion 33a. The container 30 has an internal space defined by the body portion 33, which serves as a storage space for the contents.

[0024] In this embodiment, the outer periphery of the packaged item 3 is cylindrical. In this embodiment, the outer periphery of the peripheral wall portion 33a of the body portion 33 is cylindrical. In a plan view, the outline of the outer periphery of the packaged item 3 is a circle such as a perfect circle or an ellipse, and is preferably a perfect circle.

[0025] The packaged item 3 of this embodiment has a cylindrical main body portion b1 with a cylindrical outer periphery and a small-diameter portion b2 with an outer diameter smaller than that of the cylindrical main body portion b1. In this embodiment, the cylindrical main body portion b1 is formed by a container body 32 having a cylindrical peripheral wall portion 33a, and the small-diameter portion b2 is formed by a neck portion 34. The packaged item 3 of this embodiment has a step portion 38 formed by the difference in outer diameter between the cylindrical main body portion b1 and the small-diameter portion b2, i.e., the difference in outer diameter between the container body 32 and the neck portion 34 (see FIG. 4). The step portion 38 is a portion where a difference in height occurs between the upper surface of the neck portion 34 and the top surface 36 of the container body 32, and the top surface 36 of the container body 32 is one step lower than the upper surface of the neck portion 34.

[0026] A male thread ridge (not shown) is formed on the outer circumferential surface of the neck portion 34. The male thread ridge can be threadably engaged with a female thread ridge (not shown) formed on the inner circumferential surface of the cap body 4a of the cap 4. In other words, the cap 4 is detachably screwed onto the neck portion 34. The cap 4 comprises a cap body 4a, a pressing portion 4b located radially inward of the cap body 4a, and a lid portion 4c that covers the pressing portion 4b (see FIG. 4). A known pump mechanism is provided within the pressing portion 4b. When the cap 4 is screwed onto the neck portion 34, the cap body 4a is disposed around the neck portion 34. The pressing portion 4b comprises a nozzle portion that dispenses the contents, and is configured to be able to be pressed downward relative to the cap body 4a. By pressing down the pressing portion 4b, the pump mechanism sucks up the contents within the container body 32 and allows them to be dispensed from the nozzle portion provided in the pressing portion 4b.

[0027] The packaging box 10 includes a spacer 2 that is housed together with the packaged item 3 inside the box body 10a (see FIG. 1). The spacer 2 is formed from a sheet material that is either integrated with the box body 10a or separate from the box body 10a. In this embodiment, the spacer 2 is formed from a sheet material that is separate from the box body 10a, and is housed inside the box body 10a in a state where it is folded along a folding portion formed on the sheet material. Hereinafter, the state where it is folded along the folding portion will be simply referred to as the "folded state," and the flat state before folding will be referred to as the "unfolded state."

[0028] Fig. 2(a) shows the spacer 2 of this embodiment in an unfolded state, and Fig. 2(b) shows the spacer 2 in a folded state along the folding portion 22. The spacer 2 of this embodiment is made of a single sheet material 20 having a longitudinal direction X1 and a transverse direction Y1 perpendicular to the longitudinal direction X1 in an unfolded state. The spacer 2 has a rectangular shape that is long in the longitudinal direction X1, and has a folding portion 22 that extends in the transverse direction Y1 formed in the center of the longitudinal direction X1. The spacer 2 has a holding main body portion 24 on one side in the longitudinal direction X1 across the folding portion 22, and has a holding piece portion 27 and an orthogonal holding piece portion 28 on the other side in the longitudinal direction X1. The vertical direction X1 coincides with the depth direction X of the packaging body 1 when the spacer 2 is folded as described below. The horizontal direction Y1 coincides with the width direction Y of the packaging body 1 when the spacer 2 is folded as described below.

[0029] In this embodiment, the holding body 24 has a rectangular cutout 25 cut inward in the horizontal direction Y1 from one side edge along the vertical direction X1 (see FIG. 2(a)). In other words, the holding body 24 forms the periphery of the cutout 25. The holding body 24 has a pair of main body end portions 24a, 24a on either side of the cutout 25 in the vertical direction X1. The pair of main body end portions 24a, 24a face each other across the cutout 25 and are aligned in the horizontal direction Y1. The holding body 24 has a shape with a portion of the annular shape missing (hereinafter also referred to as an "open ring shape"). In an open ring shape, the missing portion of the annular shape is also referred to as the "missing portion 25a." Examples of open ring shapes include a square, U-shape, and C-shape. However, any closed ring shape, such as a circular ring, a rectangular ring, or a polygonal ring such as a hexagon, can be used without any particular limitation when the missing portion 25a is included. Furthermore, the peripheral edge (outline) of the open-ring-shaped holding body portion 24 may be formed as a straight line or a curve, or the peripheral edge (outline) may be formed as a wavy line. The missing portion 25a can also be considered a part of the cutout portion 25. The holding body portion 24 of this embodiment has a U-shape and has the missing portion 25a between the pair of body end portions 24a, 24a (see FIG. 2(a)). When such missing portion 25a is included, the holding body portion 24 of this embodiment forms a rectangular ring shape. In this embodiment, the holding body portion 24 has a linear edge located on the inner side in the vertical direction X1 and extending in the horizontal direction Y1, which is formed by the bent portion 22. In other words, the bent portion 22 forms a part of the periphery of the holding body portion 24.

[0030] The spacer 2 of this embodiment has a connecting portion 27a where the holding piece portion 27 is connected to a portion of the periphery of the holding body portion 24. This connecting portion 27a is part of the outer edge (periphery) of the holding piece portion 27 and is the connection portion with the holding body portion 24. Hereinafter, the connecting portion 27a of the holding piece portion 27 is also referred to as the "single connecting portion 27a." The single connecting portion 27a of this embodiment is linear and extends in the lateral direction Y1, and overlaps with the folded portion 22. That is, in the spacer 2 of this embodiment, the folded portion 22 of the sheet material 20 is present at the single connecting portion 27a. This configuration is preferable because it allows the spacer 2 having the holding body portion 24 and the holding piece portion 27 to be efficiently formed by cutting out the sheet material. The holding piece 27 of this embodiment has a rectangular shape extending outward in the vertical direction X1 from the bent portion 22 (piece connecting portion 27a).

[0031] The spacer 2 of this embodiment has a connecting portion 28a where the orthogonal holding piece 28 is connected to a part of the periphery of the holding body 24. This connecting portion 28a is part of the outer edge (periphery) of the orthogonal holding piece 28 and is the connection portion with the holding body 24. Hereinafter, the connecting portion 28a of the orthogonal holding piece 28 is also referred to as the "orthogonal piece connecting portion 28a." The orthogonal piece connecting portion 28a of this embodiment is linear and extends in the lateral direction Y1, and overlaps with the bent portion 22. That is, in the spacer 2 of this embodiment, the bent portion 22 of the sheet material 20 is present at the orthogonal piece connecting portion 28a. This configuration is preferable because it allows the spacer 2 having the orthogonal holding piece 28 to be efficiently formed by cutting out the sheet material.

[0032] From the same viewpoint as above, it is preferable that the connecting portions 27a, 28a of the orthogonal holding piece portion 28 and the holding piece portion 27 are adjacent to each other on the periphery of the holding body portion 24 (see FIG. 2(a)). In this embodiment, the orthogonal holding piece portion 28 and the holding piece portion 27 are adjacent to each other in the lateral direction Y1 in the unfolded state, and the one connecting portion 27a and the orthogonal piece connecting portion 28a are continuous in the same straight line. These connecting portions 27a, 28a form the bent portion 22 extending in the lateral direction Y1.

[0033] The orthogonal holding piece 28 of this embodiment has a rectangular shape extending outward in the vertical direction X1 from the bent portion 22 (orthogonal piece connecting portion 28a). The orthogonal holding piece 28 has a width (length in the horizontal direction Y1) greater than that of the holding piece 27.

[0034] In the spacer 2 of this embodiment, the holding piece 27 and the orthogonal holding piece 28 are each bent toward the holding main body 24 (see FIG. 2(b)). That is, the spacer 2 is bent from the bending portion 22 as a starting point so that the holding piece 27 and the orthogonal holding piece 28 each stand upright relative to the holding main body 24 (see FIGS. 1 and 3). In this folded state, the orthogonal holding piece 28 extends in a direction normal to the holding main body 24. The extending direction of the orthogonal holding piece 28 coincides with the height direction Z of the package 1.

[0035] The holding piece portion 27 can close the notch 25a in a freely releasable manner. As shown in FIG. 3 described below, the holding piece portion 27 can close the notch 25a by being bridged between a pair of main body end portions 24a, 24a. From this perspective, the length of the holding piece portion 27 in the direction (longitudinal direction X1) perpendicular to the bending line of the bending portion 22 (piece connecting portion 27a) is preferably such that, in the above-mentioned folded state, the tip of the holding piece portion 27 overlaps with the main body end portion 24a distal to the holding piece portion 27 when viewed from the normal direction of the main body end portion 24a. The main body end portion 24a distal to the holding piece portion 27 is the main body end portion 24a to which the holding piece portion 27 is not connected. When the holding piece 27 closes the missing portion 25a, a closed ring shape can be formed by the holding body 24 and the holding piece 27. On the other hand, when the holding piece 27 opens the missing portion 25a, an open ring shape can be formed by the holding body 24. Hereinafter, the state in which the holding piece 27 closes the missing portion 25a is also referred to as the "closed state." Furthermore, the annular structure formed by the holding body 24 and the holding piece 27 in the closed state is also referred to as the "annular holding portion 26."

[0036] In the package 1, the spacer 2 is disposed so as to surround the packaged item 3 in the closed state. FIG. 3 illustrates a method for arranging the spacer 2 relative to the packaged item 3. First, as shown in FIG. 3(a), the spacer 2 of this embodiment is disposed around the packaged item 3. The packaged item 3 is inserted into the holding body 24 through the notched portion 25a, and the holding body 24 is disposed so that the inner peripheral edge of the holding body 24 partially surrounds the packaged item 3. Next, as shown in FIG. 3(b), the holding piece 27 is folded toward the holding body 24 along the one connecting portion 27a. As shown in FIG. 3(c), the tip of the holding piece 27 is inserted below the main body end 24a to which the holding piece 27 is not connected. Because the spacer 2 of this embodiment is formed from a single sheet material 20, a repulsive force acts upon the folding at the one connecting portion 27a. That is, a restoring force acts on the holding piece portions 27 to return to their pre-bending state, causing the tip ends of the holding piece portions 27 to rise above the portion on the side of the piece connecting portion 27a. As a result, an annular holding portion 26 is formed that surrounds the entire circumference of the packaged item 3, as shown in Figure 3(d). In this annular holding portion 26, the tip ends of the holding piece portions 27 abut against the underside of the main body end portion 24a due to the restoring force, so the closed state can be maintained better. This is advantageous because the packaged item 3 can be easily removed from the packaging box 10 by grasping the orthogonal holding piece portions 28 and pulling out the spacer 2.

[0037] From the viewpoint of facilitating the insertion of the packaged item 3 into the holding main body 24 via the notched portion 25a as described above, and from the viewpoint of generating a repulsive force for the folding, it is preferable that the holding piece 27 be connected to the peripheral edge of the pair of main body ends 24a that sandwich the notched portion 25a, on the side of the main body end 24a opposite to the notched portion 25a. In other words, it is preferable that the connecting portion 27a (folded portion 22) of the holding piece 27 is on the outer edge side of the holding main body 24 (the peripheral edge opposite to the inner edge that forms the notched portion 25). 3, the spacer 2 is disposed so as to surround the periphery of the packaged item 3. At this time, the holding body portion 24 and the holding piece portion 27 each partially surround the periphery of the packaged item 3.

[0038] In the package 1, the spacer 2 in the closed state surrounds the entire periphery of the packaged item 3 with the holding body portion 24 and the holding pieces 27 (see FIG. 1). This maintains a distance R between the packaged item 3 contained in the box body 10a and the inner surface of the box body 10a (see FIG. 4). In the package 1 of this embodiment, the holding body portion 24 protrudes radially outward from the outer periphery of the packaged item 3, and the outer edge of the holding body portion 24 interferes with the inner surface of the box body 10a, thereby providing a distance R around the packaged item 3 and between the box body 10a. This makes it less likely for the inner surface of the box body 10a to come into contact with the packaged item 3, thereby preventing scratches on the surface of the packaged item 3, particularly on the outer periphery, due to this contact. Furthermore, because the holding main body part 24 has the cutout part 25a, the holding main body part 24 can be easily positioned around the packaged item 3 via the cutout part 25a, and the cutout part 25a can be opened and closed by the holding piece part 27, making it easy to attach and detach the holding main body part 24 to the packaged item 3. Therefore, the spacer 2 of this embodiment is easy to attach to the packaged item 3.

[0039] In the packaging body 1 of this embodiment, although the packaged item 3 can rotate within the annular holding portion 26, the range of rotation is contained within the annular holding portion 26, so the packaged item 3 can be stored more stably. From the viewpoint of further stabilizing the packaged item 3 in the packaging box 10, it is preferable that the outline (outer edge) of the annular retaining portion 26 in a plan view corresponds to the horizontal cross-sectional shape of the inner surface of the peripheral wall portion 14 that forms the box main body 10a. In the packaging body 1 of this embodiment, the outline of the annular retaining portion 26 in a plan view and the horizontal cross-sectional shape of the inner surface of the peripheral wall portion 14 that forms the box main body 10a are both approximately square and correspond to each other.

[0040] In the packaging body 1 of this embodiment, the maximum length between the inner surfaces of the box body 10a is longer than the maximum length of the retaining main body portion 24, which is in turn longer than the maximum outer diameter of the packaged item 3 (maximum length between the inner surfaces of the box body 10a > maximum length of the retaining main body portion 24 > maximum outer diameter of the packaged item 3). The maximum length between the inner surfaces of the box body 10a is the longer of the lengths between the inner surfaces in the depth direction X and the width direction Y. The maximum length of the retaining main body portion 24 is the longer of the lengths in the vertical direction X1 and the horizontal direction Y1. The spacer 2 is typically provided within the box body 10a so that the maximum length of the retaining main body portion 24 corresponds to the maximum length between the inner surfaces of the box body 10a. In other words, the spacer 2 is provided such that the direction in which the length of the retaining main body portion 24 is greatest coincides with the direction in which the length between the inner surfaces of the box body 10a is greatest. From the viewpoint of further suppressing contact between the packaged item 3 and the inner surface of the box body 10a, it is preferable that the dimensions of each part of the packaging box 10 be within the following ranges. The following dimensions are based on the premise that the maximum length between the inner surfaces of the box body 10a is longer than the maximum length of the holding body part 24. The difference between the maximum length between the inner surfaces of the box body 10a and the maximum length of the holding body portion 24 is preferably 0.5 mm or more and 5 mm or less, and more preferably 1 mm or more and 3 mm or less. The difference between the maximum length of the holding body 24 and the maximum outer diameter of the packaged item 3 is preferably 0.5 mm to 20 mm, more preferably 5 mm to 10 mm. This difference between the maximum length and the maximum outer diameter roughly corresponds to the gap R between the inner surface of the box body 10a and the packaged item 3.

[0041] From the same viewpoint as above, the opening diameter L1 (see FIG. 4) of the opening defined by the annular retaining portion 26 is preferably −4 mm to 10 mm, more preferably 0 mm to 10 mm, and even more preferably 0 mm to 5 mm, relative to the outer diameter at the point where the annular retaining portion 26 is attached to the packaged item 3. The opening defined by the annular retaining portion 26 surrounds the periphery of the packaged item 3 and is formed by the inner peripheral edge of the annular retaining portion 26. The opening diameter of this opening is the maximum diametric length of the opening before attachment to the packaged item 3. Furthermore, the “outer diameter at the point where the annular retaining portion 26 is attached to the packaged item 3” refers to the outer diameter of the packaged item 3 at the height position (position in the height direction Z) where the annular retaining portion 26 is located. The spacer 2 is flexible because it is formed from a sheet material 20 such as cardboard, as described below. As a result, even if the opening diameter L1 is smaller than the outer diameter of the annular holding portion 26 at the attachment location relative to the packaged item 3, the annular holding portion 26 can be attached to the attachment location.

[0042] Because the body 33 of the packaged item 3 is the main part of the container body 32, scratches on the outer surface of the body 33 are easily noticeable and can easily mar the appearance. From the viewpoint of further suppressing scratches on the outer surface of the body 33, it is preferable that the annular retaining portion 26, i.e., the retaining main body portion 24 and the retaining piece portions 27, are arranged in the stepped portion 38. In this embodiment, the annular retaining portion 26 is arranged in the top surface 36 of the container body 32, which forms the stepped portion 38 (see FIGS. 1 and 4). In this case, from the viewpoint of more stable attachment of the annular retaining portion 26, it is preferable that the opening diameter L1 of the opening defined by the annular retaining portion 26 is smaller than the outer diameter of the step with the larger outer diameter of the stepped portion 38. In this embodiment, the step with the larger outer diameter of the stepped portion 38 is the outer diameter of the top surface 36.

[0043] As described above, the spacer 2 of this embodiment has, in the folded state, the orthogonal holding piece 28 that extends in the normal direction to the holding body 24. The orthogonal holding piece 28 of this embodiment stands upright from the holding body 24 and extends along the rear opposing plate 11b. In the packaging body 1, the orthogonal holding piece 28 extends in a direction normal to the annular holding piece 26. The orthogonal holding piece 28 extends in the axial direction (height direction Z) of the packaged item 3 within the box body 10a (see FIGS. 1 and 4). This restricts movement of the packaged item 3 in the axial direction, allowing the packaged item 3 to be stored more stably. From the viewpoint of further enhancing the above-mentioned effects, it is preferable that the orthogonal holding piece 28 in the packaging body 1 protrude outward in the axial direction (height direction Z) beyond the packaged item 3. In this embodiment, the upper edge of the orthogonal holding piece 28 in the height direction Z is located higher than the upper edge of the packaged item 3. From the viewpoint of further restricting the movement of the packaged item 3 in the axial direction, it is preferable that the upper edge of the orthogonal holding piece 28 in the packaging body 1 abut against the upper surface 13 of the box body 10a. In this case, the upper edge of the orthogonal holding piece 28 abuts against at least one of the main flap 13b and the side flaps 13c, 13d.

[0044] The outer periphery of the packaged item 3 may be transparent or non-transparent. Normally, if the outer surface of the packaged item 3 is transparent, any scratches on the packaged item 3 will be more noticeable. Since the packaging body 1 of this embodiment prevents contact with the box body 10a by the spacer 2, it is preferable to use a packaged item 3 whose outer periphery is at least partially transparent. The packaged item 3 may be partially transparent or entirely transparent. In addition, the product name or a design to improve the appearance may be printed partially or entirely on the outer surface of the packaged item 3.

[0045] Examples of contents that may be contained inside the container body 32 include cosmetics such as lotion, milky lotion, beauty serum, sunscreen, hand cream, and makeup remover; hair care products such as shampoo, conditioner, hair dye, hair styling agent, and hair growth agent; liquid soaps such as body soap and hand soap; detergents such as food detergent and laundry detergent; oral cleansers such as toothpaste; fabric softeners, bleaches, fragrances such as aroma oils; liquid medicines such as bath additives and eye drops; supplements; cleaning agents for baths, toilets, and floors; liquid foods such as soups, sauces, and dressings; and powdered foods such as spices and powdered seasonings. Normally, if the contents are transparent, scratches on the transparent outer surface of the packaged item 3 become more noticeable. The package 1 of this embodiment can prevent scratches caused by contact with the box body 10a, and is therefore preferably applicable to packaged items 3 that contain transparent contents.

[0046] The packaging body and packaging box of the present invention are not limited to the above-described embodiment. Another embodiment of the packaging body 1 and packaging box 10 of the present invention will be described below. In the following, the other embodiment will be mainly described with reference to components that differ from the embodiment shown in Figures 1 to 4, and similar components will be given the same reference numerals and will not be described again. For components that are not particularly described, the description of the embodiment shown in Figures 1 to 4 will be applied as appropriate.

[0047] Although the spacer 2 in the above-described embodiment has one orthogonal holding piece 28, the spacer 2 may have a plurality of orthogonal holding pieces 28. The spacer 2 shown in Fig. 5(a) has a pair of orthogonal holding pieces 28, 28 facing each other in the depth direction X. The pair of orthogonal holding pieces 28, 28 are connected to edges of the holding body 24 that extend in the width direction Y.

[0048] In the above-described embodiment, the spacer 2 has orthogonal holding pieces 28 that stand upward from the main holding body 24 in the folded state. However, the orthogonal holding pieces 28 are not limited to those that extend upward. The spacer 2 shown in FIG. 5(b) has a pair of orthogonal holding pieces 28, 28 that face each other in the depth direction X, and these orthogonal holding pieces 28, 28 hang down from the main holding body 24. The pair of orthogonal holding pieces 28, 28 are connected to an edge of the main holding body 24 that extends in the width direction Y, and extend downward from the edge. The spacer 2 shown in FIG. 5(b) has a bottom-facing portion 23 connected to the lower edges of the pair of orthogonal holding pieces 28, 28. The bottom-facing portion 23 corresponds to the shape of the bottom surface 12 of the box body 10a in a plan view and follows the bottom surface 12.

[0049] 5(c) has an orthogonal holding piece 28 that stands upward from the holding main body 24 and an orthogonal holding piece 28 that hangs down from the holding main body 24, and these orthogonal holding pieces 28, 28 face each other in the depth direction X. In this way, the extending directions of the multiple orthogonal holding pieces 28 may be different.

[0050] In the above-described embodiment, the spacer 2 maintains the closed state by bending the holding piece 27 at the one connecting portion 27a and inserting it under one of the main body ends 24a. Alternatively, the spacer 2 may have an engaging portion 29 whereby the holding main body 24 and the holding piece 27 engage with each other in the closed state. This engaging portion 29 is preferable because it can maintain the closed state more stably. 6(a) and (b) show one embodiment of a spacer 2 having an engaging portion 29. The spacer 2 shown in FIGS. 6(a) and (b) does not have an orthogonal holding piece portion 28. 6(a) is formed by a slit 29a formed in the main body end portion 24a distal to the holding piece portion 27. The slit 29a extends in the same direction as the width of the holding piece portion 27, and the holding piece portion 27 bent at the one connecting portion 27a is inserted into the slit 29a. The engagement portion 29 shown in FIG. 6(b) includes a protrusion 29b protruding from the inner edge of the main body end portion 24a distal to the holding piece portion 27, and a slit 29c formed in the holding piece portion 27. The protrusion 29b is inserted into the slit 29c of the holding piece portion 27 bent at the one connecting portion 27a. Instead of the form shown in FIG. 6(b), the protrusion 29b may protrude from the outer edge of one of the main body ends 24a. The protrusion 29b and the slit 29c are provided at a position where the holding main body portion 24 and the bent holding piece portion 27 partially overlap.

[0051] Next, the materials used to form the packaging body 1 in each of the above-described embodiments will be described in detail. The box body 10a of this embodiment is formed using a single blank. This blank is in an unfolded state before the box body 10a is assembled, and can be easily obtained by punching and cutting a single sheet material to form a predetermined shape.

[0052] The blank is provided with fold lines and the like at appropriate locations by applying creasing such as creasing, cutting, etc. As a result, by using the blank, it is possible to easily assemble the box body 10a having a three-dimensional shape as shown in Figure 1. The sheet material may be cardboard, a laminate of cardboard laminated with a synthetic resin film, etc. The thickness of the sheet material to be used as the blank is preferably 0.1 mm or more and 2 mm or less, more preferably 0.2 mm or more and 1 mm or less.

[0053] As described above, the spacer 2 is formed using one sheet material 20. The spacer 2 can be easily obtained by punching and cutting the sheet material 20 into a predetermined shape. The sheet material 20 is subjected to a folding process such as creasing, a cutting process, etc., to form the folded portions 22 where the connecting portions 27a, 28a are present.

[0054] The sheet material 20 forming the spacer 2 may be made of cardboard or a laminate of cardboard laminated with a synthetic resin film. The thickness of the sheet is preferably 0.05 mm or more and 3 mm or less, and more preferably 0.2 mm or more and 1 mm or less. The sheet material 20 may be made of the same material as the box main body 10a. In this case, a blank for forming the box main body 10a and the sheet material 20 for forming the spacer 2 can be obtained by punching and cutting a single sheet material (e.g., cardboard) into the blank.

[0055] The container 30, which is the packaged item 3 in this embodiment, i.e., the cap 4 and the container body 32, is a molded product made of synthetic resin such as polypropylene, polyethylene, polyethylene terephthalate (PET), chemically recycled or mechanically recycled materials of the synthetic resin, bioplastics such as polylactic acid, or glass, and can be preferably formed by injection molding.

[0056] The present invention is not limited to the above-described embodiments and can be modified as appropriate. The above-described embodiments may also be combined. For example, the packaging box 10 in the above-described embodiment is provided with a spacer 2 formed from a sheet material 20 separate from the box body 10a, but it may also be provided with a spacer 2 integrated with the box body 10a.
