Summary of the Invention

Problems to be Solved by the Invention

[0004] In such a package, different packaging materials, specifically, a mount and a heat-shrinkable film, are required for packaging the product. In addition, steps for attaching the heat-shrinkable film to the mount body and steps for shrinking the heat-shrinkable film are required. Due to the need for such a plurality of materials and the need for a plurality of steps, the cost of the package increases as the assembly cost of the package increases.

[0005] The present invention has been made in view of the above problems, and an object thereof is to provide a holder that can hold an article at a low cost and easily.

Means for Solving the Problems

[0006] To achieve the above objective, the holder according to the present invention comprises a main body portion defining a front surface and a back surface, and a locking piece disposed on the back surface of the main body portion, wherein the main body portion has a pair of openings extending parallel to each other in a first direction, and the locking piece has a tip portion disposed between the pair of openings, and a pair of protrusions projecting in opposite directions from both side edges of the tip portion in a second direction perpendicular to the first direction, wherein the article is held in the main body portion when a pair of locking portions of an article disposed on the front surface side of the main body portion protrude from the pair of openings to the back surface side, the tip portion of the locking piece is disposed between the pair of locking portions, and the pair of protrusions are locked to the pair of locking portions, respectively.

[0007] The locking piece is folded away from the main body along a fold defined in the second direction and superimposed on the back surface of the main body.

[0008] In the first direction, one side of the base end of the tip portion and the other side opposite to the first side are defined, and the tip of the tip portion extends beyond the other end of the opening defined on the other side to the other side.

[0009] The main body portion has an intermediate portion defined between the pair of openings, and one end of the intermediate portion is formed as a free end by a slit connecting the two ends of the openings defined on one side.

[0010] The article is tilted relative to the main body such that the other side of the article moves away from the surface of the main body, and the pair of locking portions of the article disengage from the pair of protrusions, thereby removing the article from the main body.

[0011] In the first direction, one side of the base end of the tip portion and the other side opposite to the first side are defined, and the pair of protrusions are positioned on the one side from an intermediate position along the entire length of the opening defined in the first direction.

[0012] The locking piece is formed from a paper material, and the direction of the fibers of the paper material is defined along the second direction. [Effects of the Invention]

Embodiments for Carrying out the Invention

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIGS. 1 and 2 are perspective views schematically showing the structure of the holder 1 according to an embodiment of the present invention. FIGS. 1 and 2 show the holder 1 during assembly (when holding an article). Hereinafter, in the drawings, the space in which the holder 1 is arranged is a three-dimensional space having a first direction D1, a second direction D2, and a third direction D3 that are orthogonal to each other. In this three-dimensional space, terms such as up and down (first direction), front, back (third direction), left, and right (second direction) are used. For example, up and down do not necessarily coincide with up and down in the gravitational direction. As will be described later, the holder 1 is, for example, assembled from a single flat paper material.

[0016] The holder 1 according to one specific example includes a main body portion 2, a pair of side wall portions 3, 3, a bottom wall portion 4, and a locking piece 5. The main body portion 2 is formed from, for example, a rectangular flat plate extending in the first direction D1 and the second direction D2. The pair of side wall portions 3, 3 are bent from the main body portion 2 at the fold lines L1 defined on both side edges of the main body portion 2 in the second direction D2, so as to rise substantially perpendicular to the third direction D3 from the main body portion 2 respectively. Each side wall portion 3 is formed from, for example, a rectangular flat plate extending in the first direction D1 and the third direction D3.

[0017] The bottom wall portion 4 is folded from the main body portion 2 at a fold L2 defined on the side edge of the main body portion 2 on the other side (lower side in Figure 1) in the first direction D1, thereby rising approximately perpendicular to the third direction D3. The bottom wall portion 4 is formed from, for example, a rectangular flat plate extending in the second direction D2 and the third direction D3. In this example, in the third direction D3, the height of the pair of side wall portions 3, 3 from the main body portion 2 is approximately equal to the height of the bottom wall portion 4 from the main body portion 2. The pair of side wall portions 3, 3 and the bottom wall portion 4 are approximately orthogonal to each other. Thus, the holder 1 as a whole has a roughly rectangular storage space S. This storage space S is open on the front and top surfaces of the holder 1.

[0018] The holder 1 further comprises a pair of connecting pieces 6, 6 that are bent from the bottom wall 4 at folds L3 defined on both side edges of the bottom wall 4 in the second direction D2. Each connecting piece 6 rises from the bottom wall 4 at approximately a right angle in the first direction D1. Each connecting piece 6 faces the outer surface of the side wall 3. Each connecting piece 6 is connected to the corresponding side wall 3 by inserting and locking its tip 61 into a notch 31 formed in the corresponding side wall 3. A portion of the tip 61 inserted into the notch 31 is positioned on the inner surface of the side wall 3. The pair of side wall 3, 3 and the bottom wall 4 are connected to each other by these pairs of connecting pieces 6, 6.

[0019] The main body 2 has a pair of openings 21, 21 that extend parallel to each other in a first direction D1. In one example, each opening 21 is formed as a long rectangle in the first direction D1. The openings 21 penetrate from the front surface 22 to the back surface 23 of the main body 2. In this example, the pair of openings 21, 21 are completely opposite to each other in a second direction D2. The main body 2 further has folded pieces 24, 24 that rise approximately perpendicularly in a third direction D3 by being folded from the main body 2 at creases L4 defined on both outer edges of the pair of openings 21, 21 defined in the second direction D2. In plan view, the contour of each folded piece 24 coincides with the contour of the opening 21.

[0020] In particular, as shown in Figure 1, the main body 2 has an intermediate section 25 defined between the pair of openings 21, 21. In one example, the intermediate section 25 is formed from a long rectangular plate in the first direction D1. One end (upper end) of the intermediate section 25, defined on the side opposite to the other side in the first direction D1 (the upper side in Figure 1), is formed as a free end by a slit 26 connecting the ends (upper ends) of the openings 21, 21 defined on the upper side in the first direction D1. In this example, the slit 26 extends in the second direction D2. Thus, the intermediate section 25 is connected to and supported by the main body 2 at its other end (lower end), defined on the lower side opposite to the upper side in the first direction D1. This prevents the tip 52 from entering the storage space S when holding an article.

[0021] Each side wall portion 3 has one or more projections 32 that extend further in the third direction D3 from the rear side edge in the third direction D3. In one example, each side wall portion 3 has two projections 32, 32 arranged in the first direction D1. The projections 32 extend on the same plane as the side wall portion 3. On the other hand, the main body portion 2 has openings 27 that face each projection 32 across a virtual straight line along the fold L1. In plan view, the contour of these openings 27 coincides with the contour of the projections 32. In this example, each projection 32 is formed in a generally trapezoidal shape, for example, tapering away from the back surface 23 of the main body portion 2 in the third direction D3. The corners of the projections 32 may also be rounded.

[0022] In particular, as shown in Figure 2, the locking piece 5 is folded from the main body 2 at a fold L5 defined on the side edge of the upper main body 2 in the first direction D1, and is superimposed on the back surface 23 of the main body 2. The locking piece 5 has an upper base end 51, a lower tip 52, and a pair of protrusions 53, 53. In the second direction D2, the upper end of the base end 51 in the first direction D1 has approximately the same dimensions as the upper end of the main body 2. The base end 51 has at least a part of a tapered portion that narrows from the upper end towards the lower end in the first direction D1. In the first direction D1, the lower end of the base end 51 is defined above one end of the openings 21, 21, i.e., the upper end.

[0023] The upper end of the tip portion 52 in the first direction D1 is connected to the lower end of the base portion 51. In one example, the tip portion 52 has a fixed width in the second direction D2 from its upper end to its lower end in the first direction D1. In this example, a portion of the tip portion 52 is superimposed on the back surface of the intermediate portion 25 of the main body portion 2. The tip portion 52 extends further down than the lower end of the intermediate portion 25 in the first direction D1. A pair of projections 53, 53 protrude from both side edges of the tip portion 52 in the second direction D2, in opposite directions. The projections 53 extend along the same plane as the tip portion 52. In this example, each projection 53 is formed in a semicircular shape, moving away from the side edge of the tip portion 52 in the second direction D2.

[0024] Figure 3 is a schematic front view showing the structure of the holder 1 according to one embodiment of the present invention, Figure 4 is its rear view, Figure 5 is its top view, Figure 6 is its bottom view, and Figure 7 is its right side view. The left side view is symmetrical to the right side view. Referring further to Figures 3 and 4 in addition to Figures 1 and 2, the pair of openings 21, 21 (intermediate section 25) of the main body 2 have a total length TL along the first direction D1. The tip 52 of the locking piece 5 has a dimension L1 that is larger than this total length TL in the first direction D1 (see Figure 4). In other words, in the first direction D1, the tip 52 extends from above the upper end of the pair of openings 21, 21 (intermediate section 25) along the intermediate section 25 to below the lower end of the pair of openings 21, 21 (intermediate section 25).

[0025] Furthermore, it is preferable that the width W1 of the tip portion 52 in the second direction D2 be set to be greater than or equal to the total width TW of the intermediate portion 25 defined in the second direction D2 (i.e., the distance between the pair of openings 21, 21 defined in the second direction D2). In one example, the width W1 of the tip portion 52 is set to be the same as the total width TW of the intermediate portion 25. In this example, both the width W1 and the total width TW are set to be constant over the entire length in the first direction D1. Therefore, in Figure 3, the tip portion 52 is completely hidden behind the intermediate portion 25, while in Figure 4, the intermediate portion 25 is hidden behind the tip portion 52. In the front and rear views of the holder 1, the pair of protrusions 53, 53 extend to a position where they enter the openings 21, 21. In this example, the lower end corner of the tip portion 52 is rounded.

[0026] Returning to Figures 3 and 4, at the tip portion 52, the pair of protrusions 53, 53 are positioned within the total length TL of the pair of openings 21, 21 in the first direction D1. In this example, the holder 1 is configured such that the entire pair of protrusions 53, 53 are completely positioned within the openings 21, 21. It is also preferable that the pair of protrusions 53, 53 are positioned above the intermediate position MP of the total length TL of the openings 21, 21 as defined in the first direction D1. In this example, the pair of protrusions 53, 53 are positioned adjacent to the upper ends of the openings 21, 21. However, the pair of protrusions 53, 53 may be positioned including the intermediate position MP, as long as the majority of the protrusions 53, 53 are positioned above the intermediate position MP.

[0027] On the other hand, referring to Figures 5 to 7 in addition to Figures 1 and 2, the heights of the folded piece 24 and the projection piece 32 are set to be equal to the back surface 23 of the main body 2. However, the height of the folded piece 24 may be set to be smaller than the height of the projection piece 32. For example, the folded piece 24 does not have to rise perpendicularly from the back surface 23 of the main body 2. Also, each connecting piece 6 has the aforementioned tip portion 61 and base portion 62. The base portion 62 is connected to the bottom wall portion 4 at the fold L3. The base portion 62 is formed in a shape that tapers upwards in the first direction D1. The tip portion 61 is connected to the upper end of the base portion 62. In this example, the tip of the tip portion 61 has a generally circular shape in plan view. On the other hand, the notch 31 is formed from a curved cut.

[0028] Figure 8 is a schematic plan view showing the structure of the holder 1, or unfolded body 10, when unfolded. The unfolded body 10 is a so-called blank. In the main body 2, the folding pieces 24 are arranged within the openings 21. Therefore, the openings 21 are formed when the folding pieces 24 are folded at the fold line L4. Similarly, the protruding pieces 32 are arranged within the openings 27. Therefore, the openings 27 and protruding pieces 32 are formed when the side wall portion 3 is folded at the fold line L1. In addition, lead lines may be formed at fold lines L1 to L5 by alternating cut lines and pressed lines to improve ease of folding. Furthermore, fold lines L1 to L5 may be cut lines, pressed lines, or perforated lines with intermittent cuts.

[0029] The holder 1, or unfolded body 10, is formed from a paper material, i.e., cardboard, having a predetermined thickness. The cardboard may have a thickness of, for example, 0.1 mm to 5 mm. The thickness of the cardboard is preferably selected appropriately according to the weight of the article to be held in the holder 1. From the viewpoint of ease of folding, a thickness of 0.2 to 0.8 mm is preferable. The cardboard forming the holder 1 may also be other paper materials, including cardboard or thick paper having a structure other than those described above. It may also be made of a material other than paper (e.g., plastic), but from the viewpoint of environmental impact, it is preferable to use paper. This unfolded body 10 is used, for example, to hold relatively lightweight articles such as lights for bicycles or toys. The holder 1 may be housed in an outer box or the like with the article inside. Furthermore, a water-resistant and oil-resistant coating layer may be formed on the surface or back surface of the cardboard forming the holder 1.

[0030] In assembling the holder 1 into the state before it holds an article, as shown in Figure 9, the side walls 3, 3 and the bottom wall 4 are folded at folds L1 and L2, respectively, in the unfolded body 10. Furthermore, the connecting piece 6 is folded at fold L3. In this way, the tip 61 of each connecting piece 6 is inserted into the notch 31 and locked into the notch 31, thereby connecting a pair of side walls 3, 3 and the bottom wall 4 at right angles to each other. In this way, the holder 1 in the state before it holds an article is assembled from a single flat paper blank, i.e., the unfolded body 10.

[0031] Next, a method for holding an article in the holder 1 will be described below. Figure 9 is a perspective view illustrating the method for holding an article in the holder 1. The article 100 is, for example, the light body of a bicycle light that can be attached to the handlebars of a bicycle. The article 100 has a housing 101. In this example, the housing 101 is formed in a generally cylindrical shape. The housing 101 is made of, for example, a resin material. The surface of the housing 101 is treated to, for example, have a glossy finish. A light module such as an LED (light-emitting diode) or a reflector (not shown) is attached to one end of the housing 101.

[0032] A pair of locking portions 102, 102 extending parallel to each other are formed on the back surface of the housing 101. In this example, the pair of locking portions 102, 102 are sliding portions having a single groove 103, 103 recessed in a direction away from each other on their opposing sides. That is, the pair of locking portions 102, 102 are formed in an L-shape such that the grooves 103 face each other in a cross section perpendicular to the direction in which each locking portion 102 extends. The article 100 is attached to the attachment by inserting a guide rail of an attachment (not shown), for example, one attached to the handlebars of a bicycle, into the grooves 103, 103 of the pair of locking portions 102, 102 and sliding the article 100 into it.

[0033] On the other hand, in the holder 1, the openings 21, 21 are formed to accommodate each of the pair of locking portions 102, 102 of the article 100. At this stage before the article 100 is held, the folding pieces 24, 24 are not folded at the crease L4. Also, the locking piece 5 is not folded at the crease L5. In Figure 9, the locking piece 5 is positioned away from the back surface 23 of the main body 2. Specifically, the locking piece 5 extends on the same plane as the main body 2. As a result, the middle portion 25 is exposed on the back surface 23 of the main body 2.

[0034] Figure 10 is a partially enlarged perspective view illustrating how an article is held in the holder 1. In Figure 10, the back surface 23 of the main body 2 of the holder 1 is shown in partial enlargement. An article 100 is placed in the storage space S of the holder 1 assembled to the state described above. At this time, with the locking portions 102, 102 of the housing 101 of the article 100 aligned with the openings 21, 21 of the main body 2, the back surface of the housing 101 of the article 100 is pressed against the surface 22 from the front surface 22 to the back surface 23. At this time, the locking portions 102, 102 of the housing 101 are pressed against the folding pieces 24, 24 from the front surface 22 to the back surface 23, respectively, causing the folding pieces 24, 24 to bend along the fold line L4. In this way, the locking portions 102, 102 protrude from the openings 21, 21 to the back surface 23 of the main body 2. The grooves 103 of each locking portion 102 protrude outward towards the back surface 23. The locking piece 5 is also bent at the fold line L5.

[0035] Figure 11 is a perspective view illustrating how an article is held in the holder 1. With the locking portions 102, 102 protruding from the back surface 23 of the main body 2, the tip portion 52 of the locking piece 5 is inserted from above between the locking portions 102, 102 while curving the base end portion 51 of the locking piece 5. At this time, a pair of protrusions 53, 53 are inserted into the grooves 103, 103 from above the locking portions 102, 102. When the base end portion 51 is superimposed on the back surface 23 of the main body 2, as shown in Figure 12, the protrusions 53, 53 of the tip portion 52 are housed in the grooves 103, 103 of the locking portions 102, 102 of the article 100. In this way, a pair of protrusions 53, 53 are locked to the corresponding pair of locking portions 102, 102.

[0036] Figure 13 is a perspective view of the holder 1 showing an article being held in the holder 1. On the back surface 23 side of the main body 2, a pair of protrusions 53, 53 of the locking piece 5 are locked to a pair of locking parts 102, 102 (grooves 103, 103) of the housing 101 of the article 100, thereby holding the article 100 in the main body 2 within the storage space S. In this example, the outer circumferential surface and bottom surface of the housing 101 may face the side walls 3, 3 and the bottom wall 4 with a predetermined gap between them. This allows for holding the article while suppressing friction on the surface of the article. The holder 1 holding the article 100 may be housed, for example, in a box-shaped packaging having dimensions to accommodate the holder 1. In this case, the protrusions 32, 32 of each side wall 3 ensure a predetermined gap between the back surface 23 of the main body 2 and the inner surface of the packaging.

[0037] Next, the method for removing an article from the holder 1 will be described below. As shown by the arrow in Figure 13, when removing the article, the lower end of the article 100 facing the upper surface of the bottom wall 4 is pulled out from the storage space S while tilting it upward and towards the front. In this way, the lower end of the article 100 is moved away from the surface 22 of the main body 2. As shown in Figure 14, the lower ends of the locking parts 102, 102 are pulled out from the openings 21, 21 towards the surface 22. The pair of locking parts 102, 102 on the back of the housing 101 displace the tip 52 of the locking piece 5 towards the surface 22 of the main body 2 based on their locking with the pair of protrusions 53, 53. Since the upper end of the intermediate part 25 of the main body 2 is formed as a free end by the cut 26, the intermediate part 25 does not obstruct the displacement of the tip 52 by the displacement of the free end of the intermediate part 25 towards the surface 22 of the main body 2.

[0038] Specifically, the tip portion 52 deforms by curving toward the surface 22 side of the main body portion 2 in the region including the area where the protrusions 53, 53 are formed. That is, a part of the tip portion 52 and the intermediate portion 25 curve and enter the storage space S toward the surface 22 side of the main body portion 2. The base portion 51 curves slightly toward the side away from the back surface 23. In addition, the lower end of the tip portion 52 deforms by curving toward the side away from the back surface 23 of the main body portion 2. In this state, as the lower end of the article 100 is further pulled toward the front and downward from the storage space S, the protrusions 53, 53 detach upward from the upper ends of the locking portions 102, 102 (grooves 103, 103), and the locking between the protrusions 53, 53 and the locking portions 102, 102 is released. In this way, the article 100 can be removed from the holder 1.

[0039] With the holder 1 described above, the article 100 is held in place by the main body 2 when a pair of locking parts 102, 102 of the article 100, which is placed on the surface 22 side of the main body 2, protrude from a pair of openings 21, 21 towards the back surface 23 side of the main body 2, and the tip 52 of the folded part 5 is positioned between the pair of locking parts 102, 102, and a pair of protruding parts 53, 53 are locked into the pair of locking parts 102, 102 (grooves 103, 103). The holder 1 only needs to have a main body 2 and a locking piece 5 that is superimposed on the back surface 23 of the main body 2, so the structure of the holder 1 itself can be simplified. The number of parts can be reduced compared to before. Therefore, the holder 1 can hold the article 100 easily and at low cost.

[0040] Furthermore, in the holder 1, the article 100 is tilted relative to the main body 2 so that its lower end moves away from the surface 22 of the main body 2, and the article 100 is removed from the main body 2 by the pair of locking parts 102, 102 of the article 100 disengaging from the pair of protrusions 53, 53. In this removal, the holder 1 tilts the lower end of the article 100 towards the front and upward relative to the main body 2, so that the locking parts 102, 102 automatically disengage from the protrusions 53, 53 of the tip 52 of the locking piece 5, and there is no need to displace or deform the locking piece 5 by hand, for example. With such a holder 1, the effort required to remove the article 100 can be reduced.

[0041] Figure 15 is a partially enlarged plan view showing a modified shape of the protrusion 53 of the locking piece 5. As shown in Figures 15(a) and (b), each protrusion 53 may be formed in a rectangular shape instead of a circular shape in plan view. The corners of the rectangle may be rounded, as shown in Figure 15(b). Also, as shown in Figures 15(c) and (d), each protrusion 53 may be formed in a trapezoidal shape in plan view. In the first direction D1 to which the tip portion 52 extends, one side of the trapezoid, either the upper or lower side, may be a straight line inclined with respect to the side edge of the tip portion 52, while the other side may be a straight line perpendicular to the side edge. Also, as shown in Figure 15(e), each protrusion 53 may be formed in a triangular shape in plan view.

[0042] In the holder 1 described above, it is preferable that the direction of the cardboard fibers forming the holder 1 is defined along the second direction D2. By aligning the direction of the cardboard fibers with the second direction D2, the base end 51 of the locking piece 5 is more likely to curve away from the back surface 23 of the main body 2, as shown in Figure 11, for example. There are also effects such as improved strength of the protruding portion 53 in locking and easier bending of the tip portion 52 of the locking piece 5. In this way, the protruding portions 53, 53 of the tip portion 52 of the locking piece 5 can be easily inserted into the grooves 103, 103 of the locking portions 102, 102 of the article 100. Furthermore, the article 100 may be any article other than the light body of a bicycle light, as long as it has locking portions 102, 102. Also, the locking portions 102 and grooves 103 may have other shapes, as long as the protruding portions 53, 53 can be locked.

[0043] Furthermore, in the holder 1, the formation of a pair of side wall portions 3, 3 or bottom wall portion 4 (and connecting piece 6) may be omitted. Moreover, in the holder 1 described above, the locking piece 5 is bent from the main body portion 2 at a crease L5 defined on the upper side edge of the main body portion 2 in the first direction D1, but as an alternative, for example, it may be configured to be bent from the right or left side edge in the second direction D2 and overlapped with the back surface 23 of the main body portion 2. Even in this case, the shape of the locking piece 5 does not need to be changed. However, the article 100 can be held more stably when the locking piece 5 has a configuration in which it is bent from the upper side edge in the first direction D1, as in the holder 1 described above.

[0044] Furthermore, in the holder 1 described above, the opening 21 is formed by folding the folding piece 24 at the fold line L4, but the folding pieces 24, 24 may be removed in advance from the main body 2 by punching. That is, the opening 21 may be formed by removing a portion of the folding piece 24. This punching of the folding piece 24 may be performed simultaneously, for example, when forming the unfolded body 10 of the holder 1. On the other hand, in the case of a configuration having a folding piece 24, the fold line for folding the folding piece 24 may be defined on the upper or lower edge of the opening 21 in the first direction D1.

[0045] Furthermore, in the above-described holder 1, the base end portion 51 of the locking piece 5 has a tapered shape that narrows from the upper end to the lower end in order to ensure the strength of the base end portion 51 itself up to the tip piece 52, but it is not limited to this shape. For example, the base end portion 51 may have other shapes such as a rectangular shape or a semicircular shape in plan view. Also, the base end portion 51 may be configured to have the same width W1 as the tip portion 52 in the second direction D2, from the upper end to the lower end in the first direction D1.
