The package for storing goods has functions to advertise goods to be stored and protect the goods as a shock absorbing material.

[1-1-2. Structure of a box body]

Next, structure of box body 6 will be described with reference to FIGS. 1 to 5. FIG. 5 is a developed view showing the state where box body 6 in accordance with the first exemplary embodiment is developed.
As shown in FIGS. 1 to 4, box body 6 is, for example, a square shaped tube, and is simply extended from an upper surface (upper side surface in FIG. 4) to a lower surface (lower side surface in FIG. 4) like a stock pot. First opening 10 with a square shape is provided in the upper surface of box body 6. As shown in FIG. 2 and FIG. 4, peripheral edge 10a of first opening 10 is provided with first turned-back section 14 that is turned back so as to be overlapped with inner surface 12a of side 12 of box body 6. First turned-back section 14 is provided over the entire circumference of peripheral edge 10a of first opening 10.
On the other hand, as shown in (d) of FIG. 3 and FIG. 4, second opening 16 with a square shape is provided in the lower surface of box body 6. Peripheral edge 16a of second opening 16 is provided with second turned-back section 18 that is turned back so as to be overlapped with inner surface 12a of side 12 of box body 6. Second turned-back section 18 is provided over the entire circumference of peripheral edge 16a of second opening 16.
Bottom lid part 20 for openably and closably covering second opening 16 is provided in the lower surface of box body 6. Bottom lid part 20 is provided to extend from tip end 18a of second turned-back section 18.
Box body 6 is assembled by folding a piece of sheet 22 shown in FIG. 5 along a fold line (dashed line shown in FIG. 5). Sheet 22 is, for example, a sheet made of transparent resin with a thickness of 0.3 mm, and is obtained by cutting an original fabric (not shown) of sheet 22 with a pressing machine or the like. Sheet 22 has first turned-back piece 24, four side sections 26, 28, 30, and 32, connecting piece 34, four second turned- back pieces 36, 38, 40, and 42, outer side flap 44, inner side flap 46, outer side flap 48, and inner side flap 50, as an area.
Each of four side sections 26 to 32 is an area for constituting side 12 of box body 6, and folded into a square shaped tube when box body 6 is assembled by folding sheet 22. Four side sections 26 to 32 correspond to a rear face of box body 6 (see (b) of FIG. 3), a left side face of box body 6 (see (f) of FIG. 3), a front face of box body 6 (see (a) of FIG. 3), and a right side face of box body 6 (see (e) of FIG. 3E), respectively. Connecting piece 34 is connected to one side connecting piece 34 is folded at approximately a right angle, and then bonded to an inner surface of side section 26 adjacent to side section 32 with adhesive section 14 of box body 6, and connected to extend over respective upper sides of four side sections 26 to 32. When box body 6 is assembled by folding sheet 22, first turned-back piece 24 is turned back at an angle of approximately 180 degrees to be overlapped with inner surface 12a of side 12 of box body 6.
Each of four second turned-back pieces 36 to 42 is an area for
respective lower sides of four side sections 26 to 32. When box body 6 is assemble by folding sheet 22, each of four second turned-back pieces 36 to 42 is turned back at an angle of approximately 180 degrees to be overlapped with inner surface 12a of side 12 of box body 6. Note that, four second turned-back pieces 36 to 42 may be formed as a single second turned-back piece, without being divided into four pieces, like first turned-back piece 24. In this case, the single second turned-back piece is divided into four portions by fold lines and formed to extend over respective lower sides of four side sections 26 to 32.
Outer side flap 44, inner side flap 46, outer side flap 48, and inner side flap 50 each are areas for constituting bottom lid section 20 of box body 6. Outer side flap 44, inner side flap 46, outer side flap 48, and inner side flap 50 each are connected to respective lower sides of second turned-back pieces 36 to 42. Semi-circular shaped notch section 52 is formed in a lower side of outer side flap 44. Semi-circular shaped notch sections 54 and 56 are formed in both sides of outer side flap 48, respectively. Slit 58 is formed at a boundary part between outer side flap 44 and second turned-back piece 36. Protruding piece 60, to be inserted into slit 58, is formed in a lower side of outer side flap 48.
When box body 6 is assembled by folding sheet 22, outer side flap 44, inner side flap 46, outer side flap 48, and inner side flap 50 each are folded as follows. First, each of inner side flaps 46 and 50 is folded at approximately a right angle to cover second opening 16. Outer side flap 44 is folded at approximately a right angle to cover inner side flaps 46 and 50 from the outside. Further, outer side flap 48 is folded at approximately a right angle to cover outer side flap 44 from the outside. At this time, protruding piece 60 is inserted into slit 58. Thus, bottom lid section 20 is formed, and second opening 16 of box body 6 is closed by bottom lid section 20. Note that, as shown in FIG. 4, bottom lid section 20 is located at a position recessed from peripheral edge 16a of second opening 16 toward a first opening 10 side.
Note that, in the case where second opening 16 of box body 6 is opened, outer side flap 48 is firstly pulled out to the outside in the state where user's fingers are hooked on each of notch sections 54 and 56, and then protruding piece 60 is drawn out from slit 58. Secondly, after outer side flap 44 is pulled out to the outside in the state where user's fingers are hooked on notch section 52, each of inner side flaps 46 and 50 is pulled out to the outside,. Thus, as shown in FIG. 8B described below, second opening 16 is opened.

[1-1-3. Structure of a lid body]

Next, structure of lid body 8 will be described with reference to FIGS. 1 to 4 and FIG. 6. FIG. 6 is a developed view showing the state where lid body 8 in accordance with the first exemplary embodiment is developed.
As shown in FIGS. 1 to 4, lid body 8 is provided to openably and closably cover first opening 10 of box body 6, and detachably attached to first opening 10. Lid body 8 has upper lid 62, suspending section 64, and insertion section 66.
Upper lid 62 has, for example, a square plate-like shape. In the case where lid body 8 is attached to first opening 10 of box body 6, upper lid 62 is disposed to cover first opening 10 of box body 6. At this time, peripheral edge 62a of upper lid 62 is disposed to be close to (or in contact with) inner surface 12a of side 12 of box body 6. Note that, as shown in FIGS. 1 and 4, upper lid 62 is disposed at a position recessed from peripheral edge 10a of first opening 10 toward a second opening 16 side.
Suspending section 64 extends upward from an upper surface of upper lid 62 in approximately a vertical direction. Suspending via hole 68 is formed in suspending section 64. For instance, a hook (not shown) for hanging packaging box 2 is inserted into suspending via hole 68 to hang packaging box 2, and thus packaging box 2 can be displayed in a storefront in the state where packaging box 2 is hung on the hook.
Insertion section 66 is provided over the entire circumference of peripheral edge 62a of upper lid 62, and extends upward from peripheral edge 62a of upper lid 62 in approximately a vertical direction. Insertion section 66 is inserted between first turned-back section 14 of box body 6 and inner surface 12a of side 12 of box body 6.
A piece of sheet 70 is folded along a fold line (dashed line shown in FIG. 6) shown in FIG. 6 to assembled lid body 8. Sheet 70 is, for example, a transparent resin sheet with a thickness of 0.3 mm, and obtained by cutting an original fabric (not shown) of sheet 70 with a pressing machine or the like. Sheet 70 has insertion pieces 72, 74, and 76, upper lid piece 78, suspending pieces 80 and 82, upper lid piece 84, and insertion pieces 86, 88, and 90, as an area.
Suspending pieces 80 and 82 are areas for constituting suspending section 64 of lid body 8. Suspending pieces 80 and 82 are folded so as to be overlapped with each other when lid body 8 is assembled by folding sheet 70. Via holes 92 and 94 are formed in suspending pieces 80 and 82, respectively. Via holes 92 and 94 are overlapped with each other to form suspending via hole 68.
Upper lid pieces 78 and 84 are areas for constituting upper lid 62 of lid body 8, and each are folded at approximately a right angle when lid body 8 is assembled by folding sheet 70.
Insertion pieces 72 to 76 and insertion pieces 86 to 90 each are areas for constituting insertion section 66 of lid body 8, and folded at approximately a right angle when lid body 8 is assembled by folding sheet 70.

[1-2. A procedure of attaching a lid body]

Next, a procedure of attaching lid body 8 to first opening 10 of box body 6 will be described with reference to FIG. 4 and FIGS. 7A and 7B. FIGS. 7A and 7B each are cross-sectional views for explaining the procedure of attaching lid body 8 to first opening 10 of box body 6.
First, in the state where a user picks suspending section 64 of lid body 8 with his or her fingers 96, upper lid 62 of lid body 8 is inserted inside box body 6 from first opening 10 of box body 6 in a direction shown by arrow P of FIG. 7A. At this time, as shown in FIG. 7B, insertion section 66 of lid body 8 is close to (or in contact with) inner surface 12a of side 12 of box body 6.
Subsequently, lid body 8 is pulled up toward the outside of box body 6 in a direction shown by arrow Q of FIG. 7B. Thus, as shown in FIG. 4, insertion section 66 of lid body 8 is inserted between first turned-back section 14 and inner surface 12a of side 12 of box body 6, so that lid body 8 is attached to first opening 10 of box body 6.

[1-3. A procedure of taking out an object]

Next, a procedure of taking out object 4 to the outside of packaging box 2 will be described with reference to FIGS. 8A and 8B. FIGS. 8A and 8B each are cross-sectional views for explaining the procedure of taking out object 4 to the outside of packaging box 2.
In the state where object 4 is accommodated inside box body 6, lid body 8 is attached to first opening 10 of box body 6 as mentioned above to package object 4 with packaging box 2. At this time, as shown in FIG. 8A, object 4 is disposed in a space surrounded by side 12, lid body 8, and bottom lid section 20 of box body 6.
In the case where object 4 is taken out to the outside of box body 6, as shown in FIG. 8A, a user firstly draws outer side flap 48, outer side flap 44, inner side flap 46, and inner side flap 50 to the outside in this order, so that second opening 16 of box body 6 is opened.
Secondly, in the state where the user picks suspending section 64 of lid body 8 with his or her fingers 96, lid body 8 is pushed in toward object 4 (i.e., toward second opening 16) in a direction shown by arrow R of FIG. 8A. At this time, as shown in FIG. 8B, insertion section 66 of lid body 8 is drawn out from between first turned-back section 14 and inner surface 12a of side 12 of box body 6. Thus, lid body 8 is removed from first opening 10 of box body 6, and first opening 10 of box body 6 is opened.
Subsequently, in the state where a lower surface of upper lid 62 of lid body 8 is in contact with an upper surface of object 4, lid body 8 is further pushed in toward object 4 in a direction shown by arrow S of FIG. 8B. Thus, object 4 is taken out to the outside of packaging box 2 from the second opening 16 of box body 6 in a direction shown by arrow T of FIG. 8B.
Note that, in the present exemplary embodiment, lid body 8 is attached to first opening 10 of box body 6 in the state where object 4 is accommodated inside box body 6, but object 4 may be accommodated in packaging box 2 from second opening 16 in the state where lid body 8 is attached to first opening 10 of box body 6. In this case, object 4 has approximately the same shape as a space surrounded by side 12, lid body 8, and bottom lid section 20 of box body 6, and can be accommodated in packaging box 2.

[1-4. Effects]

Next, effects obtained by packaging box 2 of the exemplary embodiment will be described. As mentioned above, in the present exemplary embodiment, box body 6 has first turned-back section 14 that is provided in peripheral edge 10a of first opening 10 and turned back so as to be overlapped with inner surface 12a of side 12 of box body 6. Lid body 8 has insertion section 66 that is provided in peripheral edge 62a of upper lid 62 and is to be inserted between first turned-back section 14 and inner surface 12a of side 12 of box body 6.
Accordingly, after being inserted inside box body 6 from first opening 10 of box body 6, lid body 8 can easily be attached to first opening 10 of box body 6 with such a relatively simple operation that lid body 8 is pulled up toward the outside of box body 6. Further, lid body 8 can easily be removed from first opening 10 of box body 6 with such a relatively simple operation that lid body 8 attached to first opening 10 is pushed in toward second opening 16. Thus, lid body 8 can easily be detached from and attached to box body 6.
Further, in association with the structure of box body 6 mentioned above, in sheet 22 shown in FIG. 5, first turned-back piece 24 is connected to extend over respective upper sides of four side sections 26 to 32. If sheet 22 has such a shape, the material, which is to be discarded when an original fabric of sheet 22 is cut with a pressing machine or the like, can be reduced by about 19% as compared with the conventional packaging box in which an outer side flap and an inner side flap for constituting an upper lid are formed in respective upper sides of four side sections 26 to 32, for example.
Further, in the present exemplary embodiment, first turned-back section 14 is provided over the entire circumference of peripheral edge 10a of first opening 10. This makes it possible to strengthen box body 6. Note that, even if a thickness of sheet 22 for forming box body 6 is reduced (e.g., approximately 0.2 mm to 0.3 mm), first turned-back section 14 mentioned above can maintain the intensity of box body 6.
Further, in the present exemplary embodiment, box body 6 further has second turned-back section 18 that is provided over the entire circumference of peripheral edge 16a of the second opening 16 and turned back so as to be overlapped with inner surface 12a of side 12 of box body 6. This makes it possible to strengthen box body 6. Note that, even if a thickness of sheet 22 for forming box body 6 is reduced (e.g., approximately 0.2 mm to 0.3 mm), second turned-back section 14 mentioned above can maintain the intensity of box body 6.
Further, since peripheral edge 16a of the second opening 16 forms an edge on a lower surface of box body 6, the edge allows packaging box 2 to be laid stably. This makes it possible to display packaging box 2 in a storefront in the state where packaging box 2 is laid in a showcase or the like, for example.
Further, in the present exemplary embodiment, object 4 is disposed such that, in the state where second opening 16 of bottom lid section 20 is opened, lid body 8 is pushed in toward second opening 16 to take out object 4 to the outside of packaging box 2 from the second opening 16. This makes it possible to take out object 4 easily to the outside of packaging box 2.
Further, in the present exemplary embodiment, box body 6 and lid body 8 each are made of transparent resin. Accordingly, a user can see object 4 from the outside of packaging box 2. Furthermore, first opening 10 of box body 6 is not provided with the conventional inner side flap or the like described in BACKGROUND ART. Therefore, the above-mentioned inner side flap or the like is prevented from being visible through first opening 10 when packaging box 2 is viewed from above (from a lid body 8 side). This makes it easier to design packaging box 2.

SECOND EXEMPLARY EMBODIMENT

Hereinafter, a second exemplary embodiment 2 will be described with reference to FIGS. 9 to 13.

OTHER EXEMPLARY EMBODIMENT

As mentioned above, the first to fifth exemplary embodiments are described as an example of the technique disclosed in this application. However, the technique in the disclosure is not limited to this, but can also be applied to exemplary embodiments in which modifications, substitutions, additions, omission, and the like are performed. Further, the respective components described in the first to fifth exemplary embodiments mentioned above may be combined to make a new exemplary embodiment.
Now, hereinafter, another exemplary embodiment will be described.
According to the first to fifth exemplary embodiments, box body 6 (6A to 6D) and lid body 8 (8A to 8D) each are made of transparent resin, but not limited to this. For instance, box body 6 (6A to 6D) may be made of transparent resin, and lid body 8 (8A to 8D) may be made of paper. In this way, if packaging box 2 (2A to 2D) is partially made of paper, packaging box 2 (2A to 2D) will be achieved to satisfy rigid plastic packaging container regulations of California in the United States. Note that, the above-mentioned regulation restricts that a recycled resin of 25% or more must be used as a material of a packaging box, or a resin material used for a packaging box must be reduced by 10% or more when goods are sold in California of the United States in the state where the entire circumference of an object is packaged with a rigid plastic packaging box. According to the first to fifth exemplary embodiments, lid body 8 (8A to 8D) is made of paper. Therefore, the entire circumference of object 4 is not packaged with rigid plastic, so that the above-mentioned regulation can be satisfied.
Alternatively, both box body 6 (6A to 6D) and lid body 8 (8A to 8D) may be made of paper, or both box body 6 (6A to 6D) and lid body 8 (8A to 8D) may be made of opaque resin.
According to the first to fifth exemplary embodiments, as the shape of box body 6 (6A to 6D), a square, rectangular, regular hexagonal, and circular tubes are employed, but not limited to this. For instance, an elliptical tube, a trapezoidal tube, and the like may be employed, or any other shapes may be employed optionally.
In the first to fifth exemplary embodiments, the shape of box body 6 (6A to 6D) is a tube simply extended like a stock pot, but not limited to this. For instance, a trumpet-shaped tube, i.e., has second opening 16 (16A to 16C) larger than first opening 10 (10A to 10C), may be employed. In this case, box body 6 (6A to 6D) has a cross sectional area gradually increasing from first opening 10 (10A to 10C) to second opening 16 (16A to 16C), for example.
In the first to fifth exemplary embodiments, first turned-back section 14 (14A to 14C) is provided over the entire circumference of peripheral edge 10a (10Aa to 10Ca) of first opening 10 (10A to 10C), but not limited to this. First turned-back section 14 (14A-14C) may be disposed only in at least one part of peripheral edge 10a (10Aa to 10Ca). For instance, in the first exemplary embodiment mentioned above, first turned-back section 14 may be provided only in two sides of peripheral edge 10a, which are opposite to each other, among four sides thereof.
As mentioned above, the exemplary embodiments are described as the examples of technique in the disclosure. For achieving that purpose, the accompanying drawings and detailed description are provided.
Therefore, to illustrate the technique, the components described in the accompanying drawings and the detailed description may include not only components essential for solving the problem but also components that are not essential for solving the problem. For that reason, even when the unessential components are described in the accompanying drawings and the detailed description, they do not have to be construed as being essential.
Further, since the above-mentioned exemplary embodiments illustrate the technique in the disclosure as an example, various modifications, substitutions, additions, omission can be performed within the scope of the appended claims.

INDUSTRIAL APPLICABILITY

The disclosure is applicable to a packaging box for packaging an object. Specifically, the disclosure is applicable to, for example, a clear case for packaging audio accessories goods such as headphone, beauty products such as an electric toothbrush, small goods such as a battery, or the like.
