[0009] Hereinafter, boxes 1 and 1X according to embodiments of the present invention will be described with reference to the drawings. The embodiment described below is merely an example for facilitating understanding of the present invention, and is not intended to limit the present invention. In other words, the shapes, dimensions, arrangements, and other aspects of the components described below may be modified or improved without departing from the spirit of the present invention, and the present invention naturally includes equivalents thereof.

[0010] The drawings used in this embodiment are intended to illustrate the configuration, shape, and arrangement of the components constituting the box of the present invention, and are not intended to limit the present invention. Furthermore, the drawings do not necessarily accurately represent the dimensional ratios of the length, width, height, etc. of the box. In addition, in all drawings, similar components are given the same symbols and descriptions are omitted as appropriate.

[0011] <Summary> First, an overview of the present invention will be described with reference to a box 1 according to a first embodiment, mainly with reference to Figs. 1 to 4. Fig. 1 is a perspective view showing the front side of the box 1 according to the first embodiment, Fig. 2 is a perspective view showing the rear side of the box 1 with the rear cover 3b and the inner cover 3e open, Fig. 3 is a perspective view showing the rear side of the box 1 with the top fold 3f open from the state shown in Fig. 2, and Fig. 4 is a development view of the front side of the box 1.

[0012] The box body 1 in this embodiment comprises a main body 3 having an internal storage space 2 as shown in FIG. 2, and a three-dimensional protrusion (ear-shaped protrusion 4) as shown in FIG. 1 that protrudes outward (upward) from the upper portion of the main body 3 and is formed by bending. The main body 3 has a retaining piece (grip 5) shown in Figures 3 and 4, which is disposed adjacent to the ear-shaped protrusion 4 and maintains the shape of the ear-shaped protrusion 4. The grip 5 (one grip 5X) is characterized in that it has a locking portion 5a formed therein to lock onto another portion (the other grip 5Y).

[0013] The above-mentioned "three-dimensional protrusion formed by bending" refers to a protrusion that does not extend in a plane in a static state, but is formed three-dimensionally by bending. In other words, the "bent, three-dimensional protrusion" does not include a flat, thin piece that rises from the top surface of a box body and is dynamically formed three-dimensionally, as in Patent Document 1. It is aesthetically preferable for the protruding portion to have a shape that imitates the ears of a living creature, as described below, and specifically, it is preferable for the protruding portion to have a hollow portion that can be recognized as an ear hole.

[0014] The above term "close to" does not necessarily mean adjacent, but means located close enough to be affected by the force of the joint 5 that maintains the shape of the ear-shaped protrusion 4. Preferably, there is no transverse line 6 serving as a folding line between the ear-shaped protrusion 4 and the holding piece (joint 5), or there is only one as described in this embodiment, which is preferable because this makes it easier for the holding force of the joint 5 to reach the ear-shaped protrusion 4. The above term "maintain" means to keep the shape of the ear-shaped protrusion 4 in a constant state, not to maintain it all the time, but to maintain the shape of the ear-shaped protrusion 4 to the extent that deformation of the ear-shaped protrusion 4 due to an external force of a predetermined magnitude can be suppressed.

[0015] For example, as the "holding piece", it is preferable that the locking portions 5a of the pair of joints 5X and 5Y are inserted into the slits 5b to hold the locking pieces together, as described in detail below. The holding power of the "holding piece" is further increased if the slits 5b have bent portions 5c, as described below. In addition, the "holding piece" may be one such as holding piece 45 of box body 1X according to the second embodiment described below, which increases the holding force by applying additional weight from the lower wall 43c when box body 1X is in an upright position. Furthermore, the "holding piece" is preferably formed from a single piece of material (blank material), but may be provided with a hook-and-loop fastener as an engaging portion so as to engage with the above-mentioned "other portion."

[0016] The above-mentioned "other body parts" includes, in the case where a pair of kumite 5 is provided on the left and right (kumite 5X, 5Y) as in this embodiment, one kumite 5X and the other kumite 5Y. However, the present invention is not limited to such a configuration, and the "other part" means another part of the joint 5, and may be a part that constitutes the main body 3 or other part of the box body 1.

[0017] In addition, in this document, "locking" refers to a state in which, when releasing the lock, frictional force is generated between the locking portion 5a and the object to be locked (e.g., another hand 5Y), thereby preventing the lock from being easily released. According to the above-mentioned configuration, the shape of the bent, three-dimensional ear-like protrusion 4 can be suitably maintained by the joint 5 having the locking portion 5a.

[0018] First Embodiment Next, the box 1 according to the first embodiment will be described mainly with reference to FIG. 5 in addition to FIG. 1 to FIG. Fig. 5 is a schematic explanatory diagram showing the process of locking of the locking parts 5a provided on the pair of hands 5X and 5Y. Fig. 5(a) is a diagram showing a state where the pair of hands 5X and 5Y are arranged in opposing positions. Fig. 5(b) is a diagram showing a state where the pair of hands 5X and 5Y are stacked upside down with the slit 5b as the boundary. Fig. 5(c) is a diagram showing a state where the locking parts 5a provided on the pair of hands 5X and 5Y are inserted into each other on the inside in the left-right direction along the bent part 5c.

[0019] [Overall configuration] First, the overall configuration of the box 1 will be described. As shown in FIG. 1, the box 1 comprises a main body 3 having an internal storage space 2, and a pair of ear-shaped protrusions 4 provided on the left and right ends of the upper portion of the main body 3 and protruding upward.

[0020] [Main body] As shown in FIG. 2, the main body 3 includes a frame 3x and a lid 3y that is provided so as to be openable and closable relative to the frame 3x.

[0021] [Frame] As shown in FIG. 4, the frame portion 3x includes a front wall 3a, a pair of side walls 3d, a bottom wall 3c and a bottom fold 3p that form the lower portion of the frame portion 3x, a top fold 3f that forms the upper portion of the frame portion 3x and will be described later, joints 5, and connecting pieces 3m that are connected to each of the pair of side walls 3d and the bottom wall 3c.

[0022] A hole 3h is provided at an upper front end of each of the pair of side walls 3d, and a hole 3i is provided at a lower front end of each of the pair of side walls 3d. As described below, hole 3h is adapted to receive locking protrusion 3g of top-side folded portion 3f to engage therein, and hole 3i is adapted to receive locking protrusion 3q of bottom-side folded portion 3p to engage therein, and both extend in the vertical direction.

[0023] [Lid] The lid portion 3y is composed of an inner lid 3e continuing to the rear end portion of one side wall 3d, and a rear lid 3b continuing to the rear end portion of the other side wall 3d. A hole 3k is formed in the inner lid 3e at the end portion on the side wall 3d side connected to the inner lid 3e and in the center portion in the up-down direction. A locking projection 3j is formed in the vertical center of the end of the rear cover 3b opposite to the side wall 3d connected to the rear cover 3b. The locking projection 3j of the rear cover 3b is passed through and locked in the hole 3k of the inner cover 3e, whereby the cover portion 3y is closed on the frame portion 3x.

[0024] [Protrusion] As shown in Figure 1, a pair of protrusions (ear-like protrusions 4) are provided on the upper part of the main body 3, and are formed by bending in a three-dimensional manner to resemble the ears of a living creature (a cat in the first embodiment, or a sheep in the second embodiment shown in Figure 6 and described later).

[0025] The ear-shaped protrusions 4 are shaped to resemble the ears of a living creature and protrude upward from both ends on the left and right sides of the upper part of the main body 3. In other words, the ear-shaped protrusions 4 are formed above the side wall 3d of the main body 3 (at a position overlapping an imaginary plane extending upward from the side wall 3d).

[0026] In addition, the height of the ear-like protrusions 4, which are shaped to resemble the ears of a living creature, is preferably formed to be, for example, 1 / 8 or more and 1 / 3 or less of the vertical length of the box body 1, which is recognized as the face of the living creature, as this closely resembles the ears of a living creature. Furthermore, it is preferable that the left and right width of one ear-like protrusion 4 is formed to be, for example, 1 / 10 or more and 1 / 3 or less of the left and right width of the box body 1 that is recognized as the face of the creature, as this will be closer to the creature's ears. Of course, the size of the ears of the ear-like protrusions 4 may be changed arbitrarily depending on the size of the ears of the creature represented by the box body.

[0027] Specifically, the above-mentioned "three-dimensional bending" means bending so as to expose the inside of the ear-shaped protruding portion 4, which is recognized as an ear hole of a living creature. The inside exposed from the ear-shaped protruding portion 4 according to this embodiment is open forward, and the ear-shaped protruding portion 4 is formed so as to be close to the ear of a living creature (cat).

[0028] As shown in FIG. 4, the ear-shaped protrusion 4 is formed continuously between the side wall 3d and the joint 5. The ear-shaped protruding portion 4 is folded at a crease that forms a peak, and is formed so that the inside of the ear-shaped protruding portion 4 is connected to the storage space 2 as shown in FIG.

[0029] According to the above configuration, the shape of the ear-like protrusions 4 that imitate the ears of living creatures can be appropriately maintained by the joints 5 described below.

[0030] [Holding piece] The retaining piece (knee 5) according to this embodiment retains the shape of the ear-like protruding portion 4 as described above, and is provided in at least one pair as shown in Fig. 3, with the locking portions 5a of the pair of knee 5X, 5Y locking with each other. In each of the pair of knee 5X, 5Y, a slit 5b through which the locking portion 5a provided in one knee 5X (or knee 5Y) passes is provided in the other knee 5Y (or knee 5X). The slit 5b has a bent shape.

[0031] In this specification, "bend" includes curves formed in an arc shape as well as curves formed at an angle partway along the way (V-shape, crank shape, etc.). Moreover, the angle of the bent end of the slit 5b is preferably 90 degrees or more and 180 degrees or less with respect to the extending direction of the opening side of the slit 5b, since this makes it difficult for the locking portion 5a to come off from the slit 5b.

[0032] In particular, the slit 5b according to this embodiment is formed in a shape folded back in the opposite direction as shown in FIG. Specifically, the slit 5b has a bent portion 5c at its tip which is bent 180 degrees toward the opening side (base end side) into which the locking portion 5a is inserted, and is formed in a J-shape.

[0033] The locking of the locking portions 5a of the pair of joints 5X and 5Y will be described with reference to Figs. 5(a) to 5(c). First, as shown in FIG. 5(a), the kumite 5X and the kumite 5Y are arranged on the rear side of the front wall 3a so that the slit 5b of the kumite 5X and the slit 5b of the kumite 5Y are aligned in a straight line. Next, as shown in FIG. 5(b), the pair of hands 5X and 5Y are placed one on top of the other upside down with the slit 5b as the boundary so that the slits 5b of the hands 5X and 5Y overlap each other front to back. Finally, as shown in FIG. 5(c), the joints 5X and 5Y are inserted into each other on the inner side in the left-right direction along the bent portion 5c provided in the slit 5b, so that the locking portions 5a are locked together.

[0034] According to the above configuration, the slit 5b is formed to bend (having a bending portion 5c), so that the engaging portion 5a that has entered the slit 5b can be made less likely to come out of the slit 5b regardless of the presence or absence of the ear-shaped protruding portion 4. In particular, by folding back the slit 5b in the opposite direction, it becomes more difficult for the wire to slip out through the slit 5b. In other words, the locking portion 5a of the joint 5X that has been passed through the slit 5b of the joint 5Y will not be released from the locking portion 5a unless the joint 5X is moved along the slit 5b from the tip of the slit 5b toward the bent portion 5c, and then moved toward the base end of the slit 5b.

[0035] In this embodiment, the joints 5X and 5Y are formed to have a point-symmetric shape when assembled as shown in FIG. 3, but as long as one joint 5X can be engaged with the other joint 5Y, the present invention is not limited to this configuration and the joints can have any shape.

[0036] Furthermore, when the bent portion 5c is provided on both joints 5X and 5Y, the overlap depth (engagement depth) of the joints 5X and 5Y can be increased by the amount of folding back of the slit 5b at the bent portion 5c toward the base end side, which makes it easier to prevent the joints 5X and 5Y from being released from engagement.

[0037] However, the present invention is not limited to such a configuration, and the bent portion 5c may be formed only on one side of the slit 5b between the joints 5X and 5Y. Furthermore, in a configuration in which the top-side folded portion 3f described later is provided, etc., in which it is unlikely that the lock will be released, the bent portion 5c does not necessarily need to be provided.

[0038] As shown in FIG. 4, a transverse line 6 is provided between the protrusion (ear-shaped protrusion 4) and the locking portion 5a, extending in a direction intersecting the direction connecting the ear-shaped protrusion 4 and the locking portion 5a. Specifically, "between the ear-shaped protrusion 4 and the engaging portion 5a" does not refer to a linear arrangement in the blank state (unfolded state) of the box body 1, but rather to the positional relationship relating to the arrangement of each part.

[0039] The transverse line 6 according to this embodiment is formed so as to be easily bent by being compressed in the thickness direction, and is a line that crosses the blank from one part of the outer edge to another part. However, the transverse line according to the present invention may be one that is easily bent (bent transverse line), and may be one that is formed by perforation, half cut, or the like.

[0040] According to the above configuration, by providing the transverse line 6, even when an elastic restoring force is generated in the bent ear-shaped protruding portion 4, the elastic restoring force can be prevented from being applied to the engaging portion 5a beyond the transverse line 6, thereby stabilizing the engaging state of the engaging portion 5a.

[0041] [Limited Piece] The frame portion 3x is provided with a limiting piece (top side fold portion 3f) that prevents the locking portion 5a from being released, and the top side fold portion 3f is positioned so as to cover the locking portion 5a from a direction that prevents the combined locking portion 5a from being released (direction is synonymous with orientation, and in this embodiment, the rear side).

[0042] The top folded portion 3f according to this embodiment constitutes the upper portion of the box body 1, and is formed continuously with the upper end portion of the front wall 3a. In this embodiment, the top fold portion 3f is formed with a transverse line 7a that is bent from rear to front on the back side of the joint 5, and a transverse line 7b that is located further towards the tip side than the transverse line 7a and is bent downward along the inner surface of the front wall 3a. In this manner, by providing the transverse lines 7a, 7b, the top side folded portion 3f prevents the joint 5 (5X, 5Y) from moving backward.

[0043] Specifically, the top folded portion 3f that covers the kumite 5X (locking portion 5a) from the rear side is disposed forward of the position where the locking portion 5a of the kumite 5X can be released from the slit 5b of the kumite 5Y on the horizontal plane including the kumite 5X. The top folded portion 3f is disposed so as to cover the upper, rear, and lower sides of the kumite 5X. According to the above configuration, the top folded portion 3f is disposed so as to cover the locking portion 5a, so that the locking of the locking portion 5a can be prevented from being released.

[0044] Also, notches 3n are formed at the left and right ends of the top folded portion 3f that constitutes the upper portion of the box body 1. From these notches 3n, ear-shaped protruding portions 4 protrude upward beyond the top folded portion 3f.

[0045] Connection pieces 3m connected to the side walls 3d are connected to the left and right ends of the lower wall 3c, and a bottom folded portion 3p is connected to the rear end of the lower wall 3c. The bottom folded portion 3p is for preventing the connection piece 3m, which is folded and disposed above the lower wall 3c, from spreading (unfolding). The bottom folded portion 3p is disposed to cover the connection piece 3m from above the rear so as to cover the connection piece 3m together with the lower wall 3c.

[0046] [Lock protrusion] The locking portion 5a is a first locking portion, and a second locking portion (a pair of locking protrusions 3g) that locks to the main body portion 3 is provided at the end of the limiting piece (top side fold 3f) that is folded back to cover the locking portion 5a. Specifically, the top fold 3f is folded back from the rear to the front at the cross line 7a so as to cover the locking portion 5a from the rear. In the top fold 3f according to this embodiment, a cross line 7b, which is a fold back from the front to the bottom, is provided ahead of the cross line 7a. A pair of locking projections 3g are provided protruding on both sides in the left and right direction on the tip side of the cross lines 7a and 7b. The locking projections 3g are for attaching the top fold 3f to the side wall 3d, and the pair of left and right locking projections 3g are inserted and locked into holes 3h formed in each of the pair of side walls 3d.

[0047] In this embodiment, the top folded portion 3f has a locking protrusion 3g at a tip portion extending downward beyond the cross line 7b. This is advantageous in that when the locking protrusion 3g is locked into the hole 3h, the portion extending back and forth on the base end side beyond the cross line 7b can be prevented from interfering with the work. However, the present invention is not limited to such a configuration, and the locking protrusion 3g may be provided on the tip side of the transverse line 7a folded back so as to cover the locking portion 5a. In this way, regardless of the presence or absence of the ear-shaped protrusion 4, the state in which the top folded portion 3f covers the first locking portion (locking portion 5a) can be suitably maintained.

[0048] A pair of locking projections 3q are provided on both the left and right sides of the front end (the lower end in the development view of FIG. 4) of the bottom folded portion 3p, which covers the connecting piece 3m. Specifically, the pair of locking projections 3q are for attaching the bottom folded portion 3p to the side wall 3d, and are passed through holes 3i formed in each of the pair of side walls 3d to lock onto the side wall 3d. According to the above configuration, the locking projection 3q that locks with the main body 3 is provided on the bottom folded portion 3p, so that the bottom folded portion 3p can be appropriately maintained in a state where it covers the connecting piece 3m.

[0049] <Second embodiment> In the above embodiment, the box 1 is described with respect to a configuration in which the shape of the ear-like protruding portion 4 is maintained by a pair of joints 5X, 5Y, but the present invention is not limited to such a configuration. Next, a box 1X according to a second embodiment will be described with reference mainly to FIGS. FIG. 6 is a perspective view showing the front side of the box body 1X according to the second embodiment, FIG. 7 is a perspective view showing the front side of the box body 1X with the lid portion 43y open, and FIG. 8 is an exploded view of the front side of the box body 1X.

[0050] The box body 1X of this embodiment comprises a main body 43 having an internal storage space 42 as shown in FIG. 7, and a three-dimensional protrusion (ear-shaped protrusion 44) that protrudes outward (outside both sides) from the upper portion of the main body 43 and is bent. The main body 43 has a holding piece 45 (a lid 43y) that is disposed adjacent to the ear-shaped protrusion 44 and that holds the shape of the ear-shaped protrusion 44. The cover portion 43y is formed with a locking portion 45a that locks with another portion (a hole 43e formed in a lower wall 43c of the main body portion 43, which will be described later). The holding piece 45 according to this embodiment also functions as a lid portion 43y that closes the upper side and the front side of the accommodation space . The ear-shaped protruding portion 44 according to this embodiment is formed above the side wall 43d of the main body portion 43 (at a position overlapping an imaginary plane extending upward from the side wall 43d).

[0051] According to the above-mentioned configuration, the shape of the bent, three-dimensional ear-shaped protrusion 44 can be maintained by the holding piece 45 having the locking portion 45a.

[0052] As shown in FIG. 7, the main body 43 includes a frame 43x and a lid 43y that is provided so as to be openable and closable relative to the frame 43x.

[0053] As shown in Figures 7 and 8, the frame portion 43x includes a front wall 43a (also referred to as a front side erected portion 43f (limiting piece)), a pair of side walls 43d, inner walls 43s connected to each of the pair of side walls 43d, a bottom wall 43c, a joint 5, and a rear wall 43b.

[0054] The front wall 43a is formed with a height lower than the side wall 43d and a width shorter than the rear wall 43b. A pair of locking projections 43g are formed on the upper part (lower part in FIG. 8) of the front wall 43a so as to protrude to the left and right. The pair of side walls 43d are connected to the left and right sides of the rear wall 43b.

[0055] The inner wall 43s is connected to the front ends (the outer ends in the left-right direction in Figure 8) of a pair of side walls 43d, and a hole 43h that penetrates in the front-to-rear direction is formed on the upper side of the portion connected to the pair of side walls 43d. The hole 43h is adapted to receive and engage the locking projection 43g of the front wall 43a. The lower wall 43c is formed in a trapezoid shape with the part connected to the rear wall 43b as the long side and the part connected to the front wall 43a as the short side, and a hole 43e penetrating vertically is formed in the center of the long side. As described later, the locking portion 45a of the holding piece 45 is passed through and locked in the hole 43e. The pair of joints 5 (5X, 5Y) are connected to the lower ends of the pair of side walls 43d, respectively.

[0056] As shown in FIG. 6, a pair of protrusions (ear-shaped protrusions 44) are provided on the upper part of the main body 43, have a shape imitating the ears of a living creature (a sheep in the second embodiment), and are formed by bending in a three-dimensional manner. The inside exposed from the ear-shaped protrusions 44 according to this embodiment is open outward in the left and right direction, and the ear-shaped protrusions 44 are formed so as to resemble the ears of a living creature (sheep). The ear-shaped protruding portions 44 protrude outward in the left-right direction from both ends on the left and right sides of the upper portion of the main body portion 43. The ear-shaped protruding portions 44 are folded along creases that form the upper and lower ends on the outer left-right direction, and are formed so that the inside of the ear-shaped protruding portions 44 is connected to the storage space 42, as shown in FIG.

[0057] As shown in FIG. 8, a transverse line 46 is provided between the protrusion (ear-shaped protrusion 44) and the locking portion 45a, extending in a direction intersecting the direction connecting the ear-shaped protrusion 44 and the locking portion 45a. Specifically, "between the ear-shaped protrusion 44 and the engaging portion 45a" does not refer to a linear arrangement in the blank state (unfolded state) of the box body 1X, but refers to the positional relationship relating to the arrangement of each part.

[0058] The transverse line 46 in this embodiment, like the transverse line 6 in the first embodiment, is formed so as to be easily bent by being compressed in the thickness direction, and is a line that crosses the blank from one part of the outer edge to another part. However, the transverse line according to the present invention may be one that is easily bent (bent transverse line), and may be one that is formed by perforation, half cut, or the like.

[0059] According to the above configuration, the provision of the transverse line 46 makes it possible to prevent the application of an elastic restoring force to the locking portion 45a beyond the transverse line 46 even in a state in which an elastic restoring force is generated in the bent ear-shaped protruding portion 44 or on the front side of the holding piece 45, which is on the base end side of the transverse line 46. This makes it possible to stabilize the locked state of the locking portion 45a. According to the above-mentioned configuration, the shape of the ear-like protrusion 44 that imitates the ear of a living creature can be appropriately maintained by the holding piece 45.

[0060] As described above, the frame portion 43x is provided with a restricting piece (front side standing portion 43f) that prevents the locking portion 5a shown in Fig. 8 from being released. The front side standing portion 43f is disposed so as to cover the locking portion 5a from the direction that prevents the locking portion 5a from being released when combined with the frame portion 43x (the front side in this embodiment).

[0061] The front side erected portion 43f (front wall 43a) according to this embodiment is bent upward from the front side of the lower wall 43c along a transverse line 47a and erected in front of the locking portion 5a. Specifically, on a horizontal plane including the kumite 5Y, the front side erected portion 43f is arranged rearward of the position where the locking portion 5a of the kumite 5Y separates from the slit 5b of the kumite 5X and the lock is released, and is arranged so as to cover the front of the kumite 5Y. According to the above configuration, the front side erected portion 43f is disposed so as to cover the locking portion 5a, so that the locking of the locking portion 5a can be prevented from being released.

[0062] Furthermore, a pair of locking projections 43g are provided on both the left and right sides of the upper part of the front side standing part 43f (front wall 43a) so as to protrude outward in the left-right direction. The locking projections 43g are for attaching the front side standing part 43f to the side wall 43d, and are locked by being inserted into holes 43h that are provided on the front side of the upper part of each of the side walls 43d and extend in the up-down direction.

[0063] The locking portion 45a passes through a hole 43e opened downward in the bottom wall 43c from bottom to top and is locked to the edge of the hole 43e. With this configuration, when the box body 1X is in an upright position, the weight of the box body 1X acting downward is applied to the bottom wall 43c, so that the locking portion 45a can be prevented from coming off downward relative to the hole 43e and being released from the locking.

[0064] In the above-described embodiment, the up-down direction of the boxes 1 and 1X is defined and then described. However, this definition is for the purpose of describing the positional relationship, and the up-down direction and the direction of gravity do not necessarily coincide with each other.

[0065] Furthermore, the various components of the box according to the present invention do not need to exist independently of one another. It is acceptable for multiple components to be formed as a single member, for one component to be formed from multiple members, for one component to be a part of another component, or for part of one component to overlap with part of another component.
