Abstract

To provide a storage object protection box which can be easily opened.SOLUTION: The portable electronic device includes a hollow storage case 3 capable of storing a wristwatch 2, and an exterior case 4 capable of switching between a closed state of covering at least an upper part of the storage case 3 and an open state of opening at least the upper part of the storage case 3, and the exterior case 4 has a foldable part 8 capable of being folded so as to be convex upward under the storage case 3, and the foldable part 8 is vertically displaceable with respect to a placement surface T on which the exterior case 4 is placed, thereby switching the exterior case 4 between the closed state and the open state. Therefore, since the crease portion 8 that can be folded so as to protrude upward below the housing case 3 can be vertically displaced with respect to the placement surface T on which the outer case 4 is placed, the outer case 4 can be switched between the closed state and the open state, and thus the outer case 4 can be easily opened.SELECTED DRAWING: Figure 4

Description

[Technical Field]

[0001] The present invention relates to a storage item protection box for storing storage items. [Background technology]

[0002] For example, in a storage item protection box, as described in Patent Document 1, a structure is known in which a first case member and a second case member are connected by a hinge portion so that they can be opened and closed, and a pressing operation portion is provided on the first case member corresponding to the central portion of the hinge portion, separate from the hinge portion, and the second case member is opened relative to the first case member by pressing this pressing operation portion. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 3137123

[0004] In this type of storage item protection box, a bending groove is provided on the inside of the pressing operation part, so that when the pressing operation part is pressed inward from both sides of the first case member while holding the first case member in the hand, the pressing operation part is deformed so as to bend due to the bending groove. As a result, in this storage item protection box, the deformation of the pressing operation part pushes the second case member apart relative to the first case member, opening the first and second case members. Summary of the Invention [Problem to be solved by the invention]

[0005] However, with such a storage item protection box, there is a problem that it is difficult to open; for example, unless the pressing operation part is deformed toward the inside of the first case member by holding the first case member in one hand and pinching it from both sides, the second case member cannot be pushed apart relative to the first case member to open it.

[0006] The problem to be solved by the present invention is to provide a storage item protection box that can be easily opened. [Means for solving the problem]

[0007] This invention is a storage item protection box comprising a hollow storage member capable of storing items, and an exterior member switchable between a closed state that covers at least the upper part of the storage member and an open state that leaves at least the upper part of the storage member open, wherein the exterior member has a fold portion below the storage member that can be folded so as to form an upward convex shape, and the fold portion is displaceable up and down relative to a loading surface on which the exterior member is placed, thereby allowing the exterior member to be switched between the closed state and the open state. [Effects of the Invention]

[0008] According to this invention, it can be easily opened. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] (First embodiment) A first embodiment of a storage item protection box 1 to which the present invention is applied will be described below with reference to FIGS. As shown in Figures 1 to 4, this storage item protection box 1 comprises a storage case 3, which is a hollow storage member capable of storing the stored item, a wristwatch 2, and an exterior case 4, which is an exterior member that covers this storage case 3 in an openable and closable manner.

[0011] As shown in Figures 3 and 4, the storage case 3 and the exterior case 4 are made of two layers of paper material, with thick paper sandwiched between thin paper. The exterior case 4 is switchable between a closed state in which it covers at least the top of the storage case 3 and a closed state in which it leaves at least the top of the storage case 3 open. The exterior case 4 includes a front case member 6, which is a first exterior member, and a rear case member 7, which is a second exterior member.

[0012] As shown in Fig. 3, the outer case 4 has a fold 8 at the bottom of the storage case 3 that can be folded upward (in the Y-axis direction in Fig. 3) to form a convex shape. This fold 8 is not made of cardboard or the like, but is made of a thin paper material such as tape. As shown in Fig. 4, this fold 8 bends up and down relative to the placement surface T on which the outer case 4 is placed, thereby enabling the outer case 4 to be switched between a closed state and an open state, as shown in Figs. 3 and 4. As a result, the opposing lower ends of the front case member 6 and the rear case member 7 are foldably connected by the fold 8.

[0013] 1 and 3, the front case member 6 is formed in a box shape such that the lower side placed on the placement surface T is longer in the front-to-rear direction (left-to-right direction: X-axis direction in FIG. 3) than the upper side, and is open to the rear (right side in the X-axis direction in FIG. 3). The rear case member 7 is formed in a box shape such that the lower side placed on the placement surface T is shorter in the front-to-rear direction (left-to-right direction: X-axis direction in FIG. 3) than the upper side, and is open to the front (left side in the X-axis direction in FIG. 3). As a result, the exterior case 4 is configured to have a substantially rectangular box shape when the fold portion 8 is placed on the placement surface T and the front case member 6 and the rear case member 7 are in a closed state where they are closed.

[0014] 3, the height of the upper side of the front case member 6 is slightly higher than the height of the upper side of the rear case member 7. In other words, a step 9 that makes it easy to hook a fingertip F is provided at the boundary between the upper surface of the front case member 6 and the upper surface of the rear case member 7. As shown in FIG. 4, the front case member 6 and the rear case member 7 rotate in different directions, i.e., in directions away from each other, about the fold portion 8 as the fold portion 8 is displaced upward relative to the placement surface T, thereby switching from a closed state to an open state.

[0015] 3, the storage case 3 has a top surface 3a that slopes downward toward the rear (right side in FIG. 3) because the height of the front side that is placed inside the front case member 6 is higher than the height of the rear side that is placed inside the rear case member 7. When the exterior case 4 is in a closed state, the storage case 3 also has a bottom surface 3b that is placed at the bottom inside the exterior case 4, a front surface 3c that is placed on the front side inside the front case member 6, a rear surface 3d that is placed on the rear side inside the rear case member 7, and side surfaces 3e that are placed on both side surfaces inside the exterior case 4.

[0016] Furthermore, as shown in Fig. 3, this storage case 3 has two reinforcing portions 3f located respectively at the front and rear sides of the interior. The top surface 3a, bottom surface 3b, front surface 3c, rear surface 3d, side surface 3e, and reinforcing portions 3f of the storage case 3 are each made of paper material in which cardboard is sandwiched between thin paper. In this case, a first storage inclined surface 3h corresponding to a first exterior inclined surface 6b (described later) of the outer case 4 is provided at the front lower portion of the storage case 3. Furthermore, a second storage inclined surface 3j corresponding to a second exterior inclined surface 7b (described later) of the outer case 4 is provided at the rear lower portion of the storage case 3.

[0017] 3 and 4, the top surface 3a of the storage case 3 is provided with an insertion hole 3g through which the watch band 2b is inserted from above into the storage case 3. When the watch band 2b is inserted into the storage case 3 through the insertion hole 3g, the bottom of the watch band 2b comes into contact with the bottom surface 3b of the storage case 3, thereby holding the watch case 2a in a state where it protrudes above the top surface 3a. The rear side of the storage case 3 is fixed to the front case member 6 with an adhesive or the like, in a state where it can be rotated up and down within the rear case member 7.

[0018] Meanwhile, the lower part of the outer case 4, i.e., the lower part of the front case member 6, is provided with a first outer lower surface 6a, which is parallel to the mounting surface T when the outer case 4 is closed and inclined at a predetermined angle θ1 with respect to the mounting surface T when the outer case 4 is open, as shown in Figures 3 and 4, and a first outer inclined surface 6b, which is inclined at a predetermined angle θ2 with respect to the mounting surface T when the outer case 4 is closed and is parallel to the mounting surface T when the outer case 4 is open.

[0019] Similarly, as shown in Figures 3 and 4, the lower part of the rear case member 7 is provided with a second exterior lower surface 7a that is parallel to the mounting surface T when the exterior case 4 is closed and is inclined at a predetermined angle θ1 relative to the mounting surface T when the exterior case 4 is open, and a second exterior inclined surface 7b that is inclined at a predetermined angle θ2 relative to the mounting surface T when the exterior case 4 is closed and is parallel to the mounting surface T when the exterior case 4 is open.

[0020] 3 and 4, the predetermined angle θ1 at which the first exterior lower surface 6a and the second exterior lower surface 7a are inclined relative to the placement surface T when the exterior case 4 is in the open state is the same as the predetermined angle θ2 at which the first exterior inclined surface 6b and the second exterior inclined surface 7b are inclined relative to the placement surface T when the exterior case 4 is in the closed state. When the fold portion 8 of the exterior case 4 is displaced upward to open the front case member 6 and the rear case member 7, the front case member 6 rotates about the boundary between the first exterior lower surface 6a and the first exterior inclined surface 6b as a fulcrum P1, and the rear case member 7 rotates about the boundary between the second exterior lower surface 7a and the second exterior inclined surface 7b as a fulcrum P2.

[0021] As a result, when the exterior case 4 is in the open state, as shown in Figure 4, the storage case 3 is supported by the front case member 6 and the rear case member 7. That is, when the exterior case 4 is in the open state, the first exterior inclined surface 6a and the second exterior inclined surface 7a are placed on the placement surface T in a state parallel to it, and the storage case 3 is supported by the first exterior inclined surface 6a and the second exterior inclined surface 7a. In this case, when the exterior case 4 is in the open state, the rear side of the storage case 3, which is fixed within the front case member 6, rises up into the rear case member 7, and the top surface 3a and the watch case 2a are supported in a substantially horizontal state.

[0022] 3 and 4, a restricting member 10 is provided between the storage case 3 and the rear case member 7 to restrict the range of rotation between the front case member 6 and the rear case member 7. This restricting member 10 is a strip of paper such as tape, with one end attached to the second storage inclined surface 3j on the rear side of the storage case 3 and the other end attached to the second exterior inclined surface 7b of the rear case member 7, so that when the exterior case 4 is in the open state, the restricting member 10 is stretched between the second storage inclined surface 3j on the rear side of the storage case 3 and the second exterior inclined surface 7b of the rear case member 7.

[0023] That is, as shown in FIG. 3, when the outer case 4 is in a closed state, this regulating member 10 extends diagonally upward and is folded back with one end attached to the second storage inclined surface 3j on the rear side of the storage case 3, and the other folded back end is attached from top to bottom to the second outer inclined surface 7b of the rear case member 7.

[0024] 4, when the front case member 6 and the rear case member 7 rotate about the fold 8 and the first exterior inclined surface 6a and the second exterior inclined surface 7a are placed on the placement surface T, the restricting member 10 is stretched across the upper end of the second storage inclined surface 3j and the upper end of the second exterior inclined surface 7b. In this way, the restricting member 10 restricts the rotation range of the front case member 6 and the rear case member 7.

[0025] Next, a case where such a stored item protection box 1 is used will be described. First, the wristwatch 2 is stored in the storage case 3 attached to the front case member 6 of the exterior case 4. At this time, as shown in Figure 4, the front case member 6 and rear case member 7 of the exterior case 4 are opened to expose the storage case 3. In this state, the watch band 2b is inserted into the insertion hole 3g provided in the top surface 3a of the storage case 3, and the lower part of the watch band 2b is brought into contact with the bottom surface 3b of the storage case 3. This supports the wristwatch case 2a in a state where it protrudes above the top surface 3a.

[0026] When covering storage case 3 containing wristwatch 2 with outer case 4 in this way, front case member 6 and rear case member 7 are rotated toward each other around fold 8, as shown in Figure 3. Then, the first outer lower surface 6a of front case member 6 and the second outer lower surface 7a of rear case member 7 are brought into a state parallel to the placement surface T. When this is done, front case member 6 and rear case member 7 close, and storage case 3 containing wristwatch 2 is covered by and stored within outer case 4.

[0027] 3, the edge on the open side of the front case member 6 and the edge on the open side of the rear case member 7 come into contact with each other, and the outer case 4 is in a closed state. In this state, the first outer lower surface 6a of the front case member 6 and the second outer lower surface 7a of the rear case member 7 are placed on the placing surface T, and the first outer inclined surface 6b of the front case member 6 and the second outer inclined surface 7b of the rear case member 7 are each inclined at a predetermined angle θ2 with respect to the placing surface T, and the outer case 4 is placed on the placing surface T.

[0028] When the exterior case 4 containing the storage case 3 is placed in a closed state on the placement surface T, the upper surface 3a of the storage case 3 is tilted downward at the rear so that the front side of the upper surface 3a is higher and the rear side is lower, and the wristwatch case 2a is also positioned with the rear side tilted downward. Furthermore, when the exterior case 4 is placed in a closed state on the placement surface T, the height of the upper side of the front case member 6 is higher than the height of the upper side of the rear case member 7, and therefore a step 9 is provided at the boundary between the upper surface of the front case member 6 and the upper surface of the rear case member 7 to make it easier to hook a fingertip F.

[0029] Next, to open the exterior case 4 and expose the wristwatch 2, hook your fingertip F on the step 9 located at the boundary between the top surface of the front case member 6 and the top surface of the rear case member 7, and pull the top of the front case member 6 diagonally downward toward you. This causes the front case member 6 and the rear case member 7 to rotate in different directions, i.e., away from each other, around the fold 8, as shown in Figure 4.

[0030] At this time, the fold 8 is displaced so as to convex upward on the placement surface T. When the fold 8 is displaced upward in this way and the front case member 6 and the rear case member 7 are opened, the front case member 6 rotates counterclockwise in Fig. 4 around the boundary between the first exterior lower surface 6a and the first exterior inclined surface 6b as fulcrum P1, and the rear case member 7 rotates clockwise in Fig. 4 around the boundary between the second exterior lower surface 7a and the second exterior inclined surface 7b as fulcrum P2.

[0031] 4, when fold portion 8 is displaced upward toward placement surface T, causing first exterior underside 6a of front case member 6 to tilt at a predetermined angle θ1 relative to placement surface T and second exterior underside 7a of rear case member 7 to tilt at a predetermined angle θ1 relative to placement surface T, first exterior inclined surface 6b of front case member 6 and second exterior inclined surface 7b of rear case member 7 are placed on placement surface T. This causes exterior case 4 to open, exposing wristwatch 2 housed in storage case 3.

[0032] At this time, the first exterior inclined surface 6b of the front case member 6 and the second exterior inclined surface 7b of the rear case member 7 are parallel to the placement surface T. Also, at this time, as shown in Fig. 4, the storage case 3 fixed inside the front case member 6 is supported in an almost horizontal state by the first exterior inclined surface 6b of the front case member 6 and the second exterior inclined surface 7b of the rear case member 7. In other words, the storage case 3 is supported in an almost horizontal state with a slight inclination so that the front side of the top surface 3a is slightly lower than the rear side.

[0033] In this case, the rear side of the storage case 3, which is placed inside the rear case member 7, is placed in a raised state inside the rear case member 7. At this time, the rotation range of the front case member 6 and the rear case member 7 is restricted by the restricting member 10. That is, when the first exterior inclined surface 6a and the second exterior inclined surface 7a are placed on the placement surface T, this restricting member 10 is stretched across the upper end of the second exterior inclined surface 3j and the upper end of the second exterior inclined surface 7b. As a result, the storage case 3, which stores the wristwatch 2, is supported in a stable state by the first exterior inclined surface 6b of the front case member 6 and the second exterior inclined surface 7b of the rear case member 7.

[0034] Furthermore, when the upper part of the front case member 6 of the open exterior case 4 is pressed with a fingertip F toward the rear case member 7, the front case member 6 and the rear case member 7 rotate around the fold 8 and move closer to each other, thereby closing the exterior case 4. At this time, the front case member 6 rotates clockwise in Fig. 4 around the boundary between the first exterior lower surface 6a and the first exterior inclined surface 6b as a fulcrum P1, and the rear case member 7 rotates counterclockwise in Fig. 4 around the boundary between the second exterior lower surface 7a and the second exterior inclined surface 7b as a fulcrum P2.

[0035] As a result, the front case member 6 and the rear case member 7 approach each other, and the outer case 4 enters a closed state. Then, when the fold portion 8 is displaced downward and placed on the placement surface T, the first exterior lower surface 6a of the front case member 6 and the second exterior lower surface 7a of the rear case member 7 are placed on the placement surface T. As a result, the outer case 4 is placed reliably and favorably on the placement surface T in a stable state in the closed state.

[0036] Thus, the storage item protection box 1 of this first embodiment comprises a hollow storage case 3 capable of storing a wristwatch 2, and an outer case 4 that can be switched between a closed state that covers at least the upper part of the storage case 3, and an open state that leaves at least the upper part of the storage case 3 open. The outer case 4 has a fold portion 8 at the bottom of the storage case 3 that can be folded so as to form an upward convex shape, and the fold portion 8 can be displaced up and down relative to the placement surface T on which the outer case 4 is placed, making it possible to switch the outer case 4 between a closed state and an open state, thereby making it easy to open the outer case 4.

[0037] That is, in this storage item protection box 1, when a part of the outer case 4 is operated with the fingertip F in the direction of opening or closing the outer case 4, the fold portion 8, which can be folded so as to form an upward convex shape at the bottom of the storage case 3, can be displaced up and down relative to the placement surface T on which the outer case 4 is placed, so that the outer case 4 can be switched between a closed state and an open state with the fingertip F, and this makes it extremely easy for even a user who has difficulty using one hand, for example, to open and close the outer case 4.

[0038] In this case, in this storage item protection box 1, the outer case 4 has a front case member 6 and a rear case member 7 that are connected at the boundary of the fold portion 8, and as the fold portion 8 displaces upward relative to the placement surface T, the front case member 6 and the rear case member 7 rotate in different directions, i.e., away from each other, around the fold portion 8, thereby switching from a closed state to an open state, so that the outer case 4 can be opened and closed simply and easily.

[0039] In other words, in this storage item protection box 1, simply by operating the upper part of the outer case 4 with the fingertips F in the opening direction (the direction of pulling the front case member 6 toward you), the fold portion 8 is displaced upward relative to the placing surface T, and the front case member 6 and the rear case member 7 can be reliably and smoothly rotated in different directions, i.e., in directions away from each other, around the fold portion 8, so that the outer case 4 can be opened simply and easily.

[0040] Similarly, in this storage item protection box 1, simply by operating the upper front side of the outer case 4 in the closing direction with the fingertips F, the fold portion 8 is displaced downward relative to the placement surface T, and the front case member 6 and the rear case member 7 can be reliably and smoothly rotated in directions that bring them closer to each other around the fold portion 8, thereby allowing the outer case 4 to be closed simply and easily.

[0041] Furthermore, in this storage item protection box 1, the lower part of the outer case 4 has a first outer lower surface 6a and a second outer lower surface 7a that are parallel to the placing surface T when in the closed state and inclined relative to the placing surface T when in the open state, and a first outer inclined surface 6b and a second outer inclined surface 7b that are inclined relative to the placing surface T when in the closed state and parallel to the placing surface T when in the open state, thereby allowing the outer case 4 to be placed stably on the placing surface T whether in the closed state or the open state.

[0042] In other words, in this storage item protection box 1, when the outer case 4 is in the closed state, the first outer underside 6a of the front case member 6 and the second outer underside 7a of the rear case member 7 can be placed parallel to the placement surface T, so that when in the closed state, the outer case 4 can be placed reliably and securely on the placement surface T in a stable state.

[0043] Similarly, in this storage item protection box 1, when the outer case 4 is in the open state, the first outer inclined surface 6b of the front case member 6 and the second outer inclined surface 7b of the rear case member 7 can be placed parallel to the placing surface T, so that when in the open state, the outer case 4 can be placed reliably and securely on the placing surface T in a stable state.

[0044] Furthermore, in this storage item protection box 1, when the storage case 3 is in the open state, it is supported by the front case member 6 and the rear case member 7, so that when in the open state, the storage case 3 can be reliably and favorably supported in a stable state by the front case member 6 and the rear case member 7.

[0045] In this case, in this storage item protection box 1, the front case member 6 and the rear case member 7 have a first exterior inclined surface 6b and a second exterior inclined surface 7b, respectively, and when the storage case 3 is in the open state, it is supported by the first exterior inclined surface 6b and the second exterior inclined surface 7b, so that when in the open state, the front case member 6 and the rear case member 7 can be placed on the placement surface T in a state parallel to it, and thereby the storage case 3 can be reliably and satisfactorily supported in a stable state by the front case member 6 and the rear case member 7.

[0046] Furthermore, in this storage item protection box 1, a regulating member 10 that regulates the rotation of the front case member 6 and the rear case member 7 is provided between the rear case member 7 and the storage case 3, and this regulating member 10 can regulate the rotation range of the front case member and the rear case member 7, so that the outer case 4 can be opened in a stable state.

[0047] In other words, when the outer case 4 is in a closed state, one end of this regulating member 10 is attached to the second storage inclined surface 3j on the rear side of the storage case 3, and the other folded end is attached from top to bottom to the second exterior inclined surface 7b of the rear case member 7.Therefore, when the outer case 4 is in an open state, the regulating member 10 can be securely and satisfactorily stretched between the upper end of the second storage inclined surface 3j and the upper end of the second exterior inclined surface 7b, thereby securely regulating the range of rotation of the front case member 6 and the rear case member 7.

[0048] (Second embodiment) Next, a second embodiment of a storage item protection box 15 to which the present invention is applied will be described with reference to Figures 5 to 8. Note that the same parts as those in the first embodiment shown in Figures 1 to 4 will be described using the same reference numerals. As shown in Figures 5 to 8, this storage item protection box 15, like the first embodiment, comprises a storage case 16, which is a hollow storage member capable of storing the stored item, i.e., a wristwatch 2, and an exterior case 17, which is an exterior member that covers this storage case 16 in an openable and closable manner.

[0049] Similar to the first embodiment, the storage case 16 and the outer case 17 are made of two sheets of paper material, each consisting of a thick piece of cardboard sandwiched between thin paper, as shown in Figures 7 and 8. The storage case 16 is formed in a substantially rectangular box shape that is open at the top (Y-axis direction in Figure 8). The lower part of this storage case 16 is provided with a storage bottom surface 16a that is parallel to the placement surface T when the outer case 17 is in a closed state, and a first storage inclined surface 16b and a second storage inclined surface 16c that are located on both sides of the storage bottom surface 16a in the opening direction (X-axis direction) and are inclined at a predetermined angle θ3 with respect to the placement surface T.

[0050] 7 and 8, a holding member 18 for holding the wristwatch 2 is provided inside the storage case 16. This holding member 18 is made of paper material consisting of thick paper sandwiched between thin paper. This holding member 18 is equipped with watch holding parts 20 that hold the ends on the 3 o'clock and 9 o'clock sides of the underside of the watch case 2a of the wristwatch 2, and a support part 21 that supports this watch holding part 20 within the storage case 16.

[0051] 7 and 8, the watch holder 20 is supported by a support part 21 at the top inside the storage case 16. An insertion hole 20a, into which the watch band 2b is inserted from above, is provided in the center of this watch holder 20. As a result, when the watch band 2b is inserted into the insertion hole 20a, the watch holder 20 holds the watch 2 with the watch case 2a exposed and the watch band 2b floating, as the ends on the 3 o'clock and 9 o'clock sides of the underside of the watch case 2a abut against the edges of the insertion hole 20a.

[0052] 7 and 8, the support part 21 has a base part 21a that is positioned at the bottom inside the storage case 16 and fixed therein by adhesive or the like, and two upright parts 21b that are provided on both ends of the base part 21a and that support both sides of the watch holder part 20. As a result, when the watch band 2b is inserted into the insertion hole 20a and the ends on the 3 o'clock and 9 o'clock sides of the underside of the watch case 2a abut against the edges of the insertion hole 20a, the support part 21 supports the watch holder part 20 when the watch 2 is held by the watch holder part 20 with the watch band 2a floating inside the storage case 16.

[0053] 7 and 8, like the first embodiment, the exterior case 17 is switchable between a closed state in which it covers and closes at least the upper part of the storage case 16, and an open state in which it opens at least the upper part of the storage case 16. This exterior case 17 includes a front case member 22, which is a first exterior member, and a rear case member 23, which is a second exterior member. Also, like the first embodiment, as shown in FIG. 8, this exterior case 4 has a fold portion 8 below the storage case 16 that can be folded to form an upward convex shape.

[0054] As in the first embodiment, this fold portion 8 is not provided with cardboard or the like, but is formed of a paper material such as a thin tape. As shown in Fig. 8, this fold portion 8 is bent and displaced up and down (in the Y-axis direction in Fig. 8) with respect to the placement surface T on which the outer case 17 is placed, thereby making it possible to switch the outer case 17 between a closed state and an open state, as shown in Figs. 7 and 8. As a result, the opposing lower ends of the front case member 22 and the rear case member 23 are foldably connected by the fold portion 8.

[0055] 7 and 8, the front case member 22 is formed in a box shape that is open to the rear (to the right in the X-axis direction in FIG. 7). The rear case member 23 is formed in a box shape that is open to the front (to the left in the X-axis direction in FIG. 7). The front case member 22 and the rear case member 23 are formed in bilaterally symmetrical shapes with respect to a vertical line L that passes through the fold portion 8.

[0056] As a result, exterior case 17 is configured to have a substantially rectangular box shape when folded portion 8 is placed on mounting surface T and front case member 22 and rear case member 23 are closed in a closed state, as shown in Fig. 7. Furthermore, as folded portion 8 is displaced upward relative to mounting surface T, front case member 22 and rear case member 23 rotate about folded portion 8 in different directions, i.e., in directions away from each other, thereby switching from a closed state to an open state, as shown in Fig. 8.

[0057] Meanwhile, the lower part of the outer case 17, i.e., the lower part of the front case member 22, is provided with a first outer lower surface 22a, which is parallel to the mounting surface T when the outer case 17 is closed and inclined at a predetermined angle θ4 with respect to the mounting surface T when the outer case 17 is open, as shown in Figures 7 and 8, and a first outer inclined surface 22b, which is inclined at a predetermined angle θ5 with respect to the mounting surface T when the outer case 17 is closed and is parallel to the mounting surface T when the outer case 17 is open.

[0058] Similarly, as shown in Figures 7 and 8, the lower part of the rear case member 23 is provided with a second exterior lower surface 23a that is parallel to the mounting surface T when the exterior case 17 is closed and is inclined at a predetermined angle θ4 with respect to the mounting surface T when the exterior case 17 is open, and a second exterior inclined surface 23b that is inclined at a predetermined angle θ5 with respect to the mounting surface T when the exterior case 17 is closed and is parallel to the mounting surface T when the exterior case 17 is open.

[0059] In this case, as shown in Figures 7 and 8, the predetermined angle θ3 at which the first storage inclined surface 16b and the second storage inclined surface 16c of the storage case 16 are inclined relative to the mounting surface T when the outer case 17 is in a closed state, the predetermined angle θ4 at which the first exterior lower surface 22a and the second exterior lower surface 23a are inclined relative to the mounting surface T when the outer case 17 is in an open state, and the predetermined angle θ5 at which the first exterior inclined surface 22b and the second exterior inclined surface 23b are inclined relative to the mounting surface T when the outer case 17 is in a closed state are the same angle (θ3 = θ4 = θ5).

[0060] In addition, when the fold portion 8 of the exterior case 17 is displaced upward to open the front case member 22 and the rear case member 23, the front case member 22 rotates counterclockwise in FIG. 8 around the boundary between the first exterior lower surface 22a and the first exterior inclined surface 22b as a fulcrum P3, and the rear case member 23 rotates clockwise in FIG. 8 around the boundary between the second exterior lower surface 23a and the second exterior inclined surface 23b as a fulcrum P4.

[0061] As a result, when the outer case 17 is in the open state, as shown in Fig. 8, the storage case 16 is supported by the front case member 22 and the rear case member 23. That is, when the outer case 17 is in the open state, the first outer inclined surface 22b and the second outer inclined surface 23b are placed on the placement surface T in a state where they are parallel to it, and thus the storage case 16 is supported by the first outer inclined surface 22b and the second outer inclined surface 23b. In this case, when the outer case 17 is in the closed state, as shown in Fig. 7, a first spacer member 24 is disposed between the first storage inclined surface 16b of the storage case 16 and the first outer inclined surface 22b of the front case member 22. This first spacer member 24 is made of a foam material and is attached to the first storage inclined surface 16b.

[0062] Similarly, when the outer case 17 is in the closed state, as shown in Fig. 7, a second spacer member 25 is disposed between the second storage inclined surface 16c of the storage case 16 and the second exterior inclined surface 23b of the rear case member 23. This second spacer member 25 is formed of a foam material, similar to the first spacer member 24, and is attached to the second storage inclined surface 16c. As a result, the fold portion 8 is located at the midpoint between the first spacer member 24 and the second spacer member 25, and as shown in Fig. 8, when the outer case 17 is in the open state, it is inserted between the first spacer member 24 and the second spacer member 25.

[0063] 7 and 8, the first spacer member 24 and the second spacer member 25 form a gap between the storage lower surface 16a of the storage case 16 and the first and second exterior lower surfaces 22a, 23a of the outer case 17. This allows the fold portion 8 to be folded so as to form an upward convex shape. Therefore, when the outer case 17 is in the open state, the fold portion 8 is positioned close to or in contact with the storage lower surface 16a of the storage case 16.

[0064] 7 and 8, a first connecting member 26 that rotatably connects the first spacer member 24 is provided on the inner surface of the first exterior inclined surface 22b of the front case member 22. Also, a second connecting member 27 that rotatably connects the second spacer member 25 is provided on the inner surface of the second exterior inclined surface 23b of the rear case member 23. The first connecting member 26 and the second connecting member 27 are made of thin paper such as thin tape.

[0065] 7 and 8, one end of the first connecting member 26 is affixed to the first exterior inclined surface 22b of the front case member 22, is folded back at the boundary between the first exterior lower surface 22a and the first exterior inclined surface 22b, and the other end is attached to the lower surface of the first spacer member 24. As a result, when the exterior case 17 is in the closed state, as shown in Fig. 7, the first connecting member 26 is folded and overlapped at the boundary between the first exterior lower surface 22a and the first exterior inclined surface 22b. Furthermore, when the exterior case 17 is in the open state, as shown in Fig. 8, the first connecting member 26 is pressed down by rotating the first exterior inclined surface 22b relative to the first spacer member 24 around the boundary between the first spacer member 24 and the first exterior lower surface 22a.

[0066] 7 and 8, one end of the second connecting member 27 is affixed to the second exterior inclined surface 23b of the rear case member 23, is folded back at the boundary between the second exterior lower surface 23a and the second exterior inclined surface 23b, and the other end is attached to the lower surface of the second spacer member 25. As a result, when the exterior case 17 is in the closed state, as shown in Fig. 7, the second connecting member 27 is folded and overlapped at the boundary between the second exterior lower surface 23a and the second exterior inclined surface 23b. Furthermore, when the exterior case 17 is in the open state, as shown in Fig. 8, the second connecting member 27 is pushed down as the second exterior inclined surface 23b rotates around the boundary between the second spacer member 25 and the second exterior lower surface 23a relative to the second spacer member 25.

[0067] When exterior case 17 is in the open state, the angle at which first exterior inclined surface 22b rotates relative to first spacer member 24 and is pressed down around the boundary between first exterior lower surface 22a and first exterior inclined surface 22b is the same as the angle at which second exterior inclined surface 23b rotates relative to second spacer member 25 and is pressed down around the boundary with second exterior lower surface 23a when exterior case 17 is in the open state. In this case, when exterior case 17 is in the open state, storage case 16 does not tilt or move within exterior case 17, maintaining the same position as when exterior case 17 is in the closed state and supporting watch case 2a in a nearly horizontal position.

[0068] Incidentally, the length of the first exterior bottom surface 22a of the front case member 22, that is, the first dimension S1 reaching from the fold line portion 8 to the first exterior inclined surface 22b on the first exterior bottom surface 22a, as shown in FIG. 7, is shorter than the first interval K1 between the first vertical line R1 extending from the center of gravity G1 of the front case member 22 to the placement surface T and the second vertical line R2 extending from the fold line portion 8 to the placement surface T (S1 < K1).

[0069] Similarly, the length of the second exterior bottom surface 23a of the rear case member 23, that is, the second dimension S2 reaching from the fold line portion 8 to the second exterior inclined surface 23b on the second exterior bottom surface 23a, as shown in FIG. 7, is shorter than the second interval K2 between the third vertical line R3 extending from the center of gravity G2 of the rear case member 23 to the placement surface T and the fourth vertical line R4 extending from the fold line portion 8 to the placement surface T (S2 < K2).

[0070] In this case, the first dimension S1 reaching from the fold line portion 8 to the first exterior inclined surface 22b on the first exterior bottom surface 22a and the second dimension S2 reaching from the fold line portion 8 to the second exterior inclined surface 23b on the second exterior bottom surface 23a are of the same length (S1 = S2) as shown in FIG. 7. Also, the first interval K1 between the first vertical line R1 extending from the center of gravity G1 of the front case member 22 to the placement surface T and the second vertical line R2 extending from the fold line portion 8 to the placement surface T is of the same length as the second interval K2 between the third vertical line R3 extending from the center of gravity G2 of the rear case member 23 to the placement surface T and the fourth vertical line R4 extending from the fold line portion 8 to the placement surface T (K1 = K2).

[0071] As a result, as shown in FIG. 7, when the exterior case 17 is in the closed state, since the first dimension S1 of the front case member 22 is shorter than the first interval K1, the center of gravity G1 of the front case member 22 is located on the front side (left side in FIG. 7) of the front case member 22 with respect to the fulcrum P3 at the lower end of the first exterior inclined surface 22b, that is, the boundary portion between the first exterior bottom surface 22a and the first exterior inclined surface 22b. For this reason, when the front case member 22 is placed on the placement surface T, as shown in FIG. 8, it naturally rotates by gravity in the opening direction around the fold line portion 8.

[0072] 7, when the exterior case 17 is in the closed state, the second dimension S2 of the rear case member 23 is shorter than the second gap K2, and therefore the center of gravity G2 of the rear case member 23 is located at the lower end of the second exterior inclined surface 23b, that is, behind the rear case member 23 (to the right in FIG. 7) of the fulcrum P4 at the boundary between the second exterior lower surface 23a and the second exterior inclined surface 23b. Therefore, when the rear case member 23 is placed on the placement surface T, it naturally rotates by gravity in the opening direction around the fold 8, as shown in FIG.

[0073] As a result, when the first exterior underside 22a and the second exterior underside 23a are placed on the placement surface T with the front case member 22 and the rear case member 23 closed, the front case member 22 and the rear case member 23 naturally rotate around the fold portion 8 as shown in Figure 8, and the exterior case 17 automatically enters an open state.

[0074] Next, a case where such a stored item protection box 15 is used will be described. First, the wristwatch 2 is stored in the storage case 16 provided inside the exterior case 17. At this time, as shown in Figures 6 and 8, the front case member 22 and the rear case member 23 of the exterior case 17 are opened to expose the storage case 16.

[0075] In this state, the watch band 2b is inserted into the insertion hole 20a provided in the watch holder 20 of the holder member 18 of the storage case 16. This causes the 3 o'clock and 9 o'clock ends of the underside of the watch case 2a to abut against the edges of the insertion hole 20a in the watch holder 20. At this point, as shown in FIG. 8, the watch band 2b is floating within the holder member 18, and the watch case 2a is placed on the watch holder 20 as shown in FIG. 6. As a result, the watch 2 is stored in the storage case 16 with the upper part exposed.

[0076] 5, when the front case member 22 and the rear case member 23 of the exterior case 17 are pinched with the hand H, the front case member 22 and the rear case member 23 rotate about the fold 8 and come close to each other and abut against each other, as shown in FIG. 7. This causes the exterior case 17 to cover the storage case 16 and enter a closed state. In this state, the first spacer member 24 is sandwiched between the first exterior inclined surface 22b and the first storage inclined surface 16b, and the second spacer member 25 is sandwiched between the second exterior inclined surface 23b and the second storage inclined surface 16c.

[0077] At this time, the first connecting members 24 connecting the first spacer members 24 and the first exterior inclined surface 22b are bent around the boundary between the first exterior lower surface 22a and the first spacer members 24, and the first connecting members 24 overlap each other. Similarly, the second connecting members 25 connecting the second spacer members 25 and the second exterior inclined surface 23b are bent around the boundary between the second exterior lower surface 23a and the second spacer members 25, and the second connecting members 25 overlap each other. In this case, gaps are provided by the first spacer members 24 and the second spacer members 25 between the first exterior lower surface 22a and the second exterior lower surface 23a of the exterior case 17 and the storage lower surface 16a of the storage case 16.

[0078] When the closed exterior case 17 is placed on the placement surface T, the exterior case 17 automatically opens. That is, at this time, as shown in Fig. 7, when the exterior case 17 is closed, the first dimension S1 of the front case member 22 is shorter than the first gap K1, and therefore the center of gravity G1 of the front case member 22 is located on the front side (left side in Fig. 7) of the front case member 22 relative to the lower end of the first exterior inclined surface 22b, i.e., the fulcrum P3 which is the boundary between the first exterior lower surface 22a and the first exterior inclined surface 22b. Therefore, when the front case member 22 is placed on the placement surface T, it naturally rotates forward by gravity around the fold 8 as the center, as shown in Fig. 8.

[0079] 7, when the exterior case 17 is in the closed state, the second dimension S2 of the rear case member 23 is shorter than the second distance K2, and therefore the center of gravity G2 of the rear case member 23 is located rearward (to the right in FIG. 7) of the lower end of the second exterior inclined surface 23b, that is, the fulcrum P4 which is the boundary between the second exterior lower surface 23a and the second exterior inclined surface 23b. Therefore, the rear case member 23 naturally rotates rearward around the fold 8, as shown in FIG.

[0080] At this time, when the fold portion 8 is displaced upward and the front case member 22 and the rear case member 23 are opened, the front case member 22 rotates counterclockwise in Figure 7 around the boundary between the first exterior lower surface 22a and the first exterior inclined surface 22b as fulcrum P3, and the rear case member 23 rotates clockwise in Figure 7 around the boundary between the second exterior lower surface 23a and the second exterior inclined surface 23b as fulcrum P4.

[0081] 8, the fold 8 is displaced upward and enters between the first spacer member 24 and the second spacer member 25. In this case, the end of the first spacer member 24 on the fold 8 side and the end of the first exterior inclined portion 22b on the fold 8 side are rotatably connected by the first connecting member 26, so when the fold 8 is displaced upward, the first exterior inclined surface 22b rotates around the boundary between the first spacer member 24 and the first exterior lower surface 22a so as to be pressed down relative to the first spacer member 24.

[0082] Similarly, as shown in Figure 8, the end of the second spacer member 25 on the fold portion 8 side and the end of the second exterior inclined portion 23b on the fold portion 8 side are rotatably connected by the second connecting member 27, so that when the fold portion 8 is displaced upward, the second exterior inclined surface 23b rotates so as to be pressed down against the second spacer member 25 around the boundary between the second spacer member 25 and the second exterior lower surface 23a.

[0083] As a result, when the first exterior lower surface 22a and the second exterior lower surface 23a are placed on the placement surface T with the front case member 22 and the rear case member 23 in a closed state, the front case member 22 and the rear case member 23 naturally rotate about the fold portion 8 as the center, and the exterior case 17 automatically enters an open state. At this time, the fold portion 8, which is tucked between the first spacer member 26 and the second spacer member 27, is positioned close to or in contact with the storage lower surface 16a of the storage case 16.

[0084] Also, at this time, first exterior inclined surface 22b of outer case 17 becomes parallel to placing surface T, and second exterior inclined surface 23b of outer case 17 also becomes parallel to placing surface T, and these first exterior inclined surface 22b and second exterior inclined surface 23b are placed in a stable state on placing surface T. In this state, storage case 16 is exposed to the outside without tilting or moving within outer case 17, due to first spacer member 24 rotatably connected to first exterior inclined surface 22b by first connecting member 26 and second spacer member 27 rotatably connected to second exterior inclined surface 23b by second connecting member 27.

[0085] Thus, the second embodiment of the stored item protection box 15 comprises a hollow storage case 16 capable of storing a wristwatch 2, and an outer case 17 that can be switched between a closed state that covers at least the upper part of the storage case 16, and an open state that leaves at least the upper part of the storage case 16 open. The outer case 17 has a fold portion 8 at the bottom of the storage case 16 that can be folded so as to form an upward convex shape, and the fold portion 8 can be displaced up and down relative to the placement surface T on which the outer case 17 is placed, making it possible to switch the outer case 17 between a closed state and an open state, which allows the outer case 17 to be easily opened, just like the first embodiment.

[0086] That is, in this storage item protection box 15, when the outer case 17 is pinched with the hands H from the front and back, the fold portion 8, which can be folded so as to form an upward convex shape at the bottom of the storage case 3, can be displaced toward the placement surface T on which the outer case 4 is placed, and when the outer case 17 is placed on the placement surface T and the hands H are released from the outer case 17, the fold portion 8 can be displaced upward toward the placement surface T, so that the outer case 17 can be switched between a closed state and an open state, and this makes it extremely easy for even a user who has difficulty using one hand to open and close the outer case 17.

[0087] In this case, in this storage item protection box 15, the outer case 17 has a front case member 22 and a rear case member 23 that are connected at the boundary of the fold portion 8, and as the fold portion 8 displaces upward relative to the placement surface T, the front case member 22 and the rear case member 23 rotate in different directions, i.e., away from each other, around the fold portion 8, thereby switching from a closed state to an open state, so that the outer case 17 can be opened and closed simply and easily.

[0088] That is, in this storage item protection box 15, simply by pinching the outer case 17 with hands H from the front and rear, the fold portion 8 is displaced so as to be pushed down toward the placement surface T, and the front case member 22 and the rear case member 23 can be reliably and smoothly rotated in directions in which they approach each other around the fold portion 8, so that the outer case 17 can be closed simply and easily.

[0089] Similarly, in this storage item protection box 15, simply by placing the outer case 17 on the placement surface T and releasing the hand H from the outer case 17, the fold portion 8 is displaced downward relative to the placement surface T, and the front case member 22 and the rear case member 23 can be reliably and smoothly rotated in different directions, i.e., in directions away from each other, around the fold portion 8, so that the outer case 17 can be opened simply and easily.

[0090] Furthermore, in this storage item protection box 15, the lower part of the exterior case 17 has first exterior undersurface 22a and second exterior undersurface 23a that are parallel to the placement surface T when in the closed state and inclined relative to the placement surface T when in the open state, and first exterior inclined surface 22b and second exterior inclined surface 23b that are inclined relative to the placement surface T when in the closed state and parallel to the placement surface T when in the open state, thereby allowing the exterior case 17 to be placed stably on the placement surface T whether in the closed state or the open state.

[0091] That is, in this storage item protection box 15, when the outer case 17 is in the closed state, the first outer underside 22a of the front case member 22 and the second outer underside 23a of the rear case member 23 can be placed parallel to the placement surface T, so that the outer case 17 can be placed well on the placement surface T when in the closed state.

[0092] Similarly, in this storage item protection box 15, when the exterior case 17 is in the open state, the first exterior inclined surface 22b of the front case member 22 and the second exterior inclined surface 23b of the rear case member 23 can be placed parallel to the placement surface T, so that when in the open state, the exterior case 17 can be placed reliably and securely on the placement surface T in a stable state.

[0093] Furthermore, in this storage item protection box 15, when the storage case 16 is in the open state, it is supported by the front case member 22 and the rear case member 23, so that when the storage case 16 is in the open state, it can be reliably and favorably supported in a stable state within the outer case 17 by the front case member 22 and the rear case member 23.

[0094] In this case, in this storage item protection box 15, the front case member 22 and the rear case member 23 each have a first exterior inclined surface 22b and a second exterior inclined surface 23b. When the storage case 16 is in an open state, it is supported by the first exterior inclined surface 22b and the second exterior inclined surface 23b. Thus, whether in a closed state or an open state, the storage case 16 can be reliably and well supported in a stable state within the exterior case 17 by the first exterior inclined surface 22b and the second exterior inclined surface 23b that are placed parallel to the placement surface T thereon.

[0095] Also, in this storage item protection box 15, when in a closed state, the first dimension S1 from the fold portion 8 of the first exterior lower surface 22a to the first exterior inclined surface 22b is shorter than the first interval K1 between the first vertical line R1 extending from the center of gravity G1 of the front case member 22 to the placement surface T (S1 < K1). Therefore, simply by placing the exterior case 17 on the placement surface T, the front case member 22 of the exterior case 17 can be automatically opened.

[0096] That is, in this storage item protection box 15, when the exterior case 17 is in a closed state, since the first dimension S1 of the front case member 22 is shorter than the first interval K1, the center of gravity G1 of the front case member 22 can be positioned on the front side (left side in FIG. 7) of the front case member 22 with respect to the fulcrum P3 at the boundary between the lower end of the first exterior inclined surface 22b, that is, the first exterior lower surface 22a and the first exterior inclined surface 22b. Thereby, the front case member 22 can be naturally rotated about the fold portion 8, so the exterior case 17 can be automatically opened.

[0097] Similarly, in this storage item protection box 15, when in a closed state, the second dimension S2 from each fold portion 8 of the second exterior lower surface 23a to the second exterior inclined surface 23b is shorter than the second interval K2 between the second vertical line R2 extending from the center of gravity G2 of the rear case member 23 to the placement surface T (S2 < K2). Therefore, simply by placing the exterior case 17 on the placement surface T, the rear case 23 of the exterior case 17 can be automatically opened.

[0098] That is, in this storage item protection box 15, when the outer case 17 is in the closed state, the second dimension S2 of the rear case member 23 is shorter than the second spacing K2, so that the center of gravity G2 of the rear case member 23 can be positioned at the lower end of the second outer inclined surface 23b, that is, at the rear side of the rear case member 23 (to the right in Figure 7) rather than the fulcrum P4 at the boundary between the second outer lower surface 23a and the second outer inclined surface 23b. This allows the rear case member 23 to rotate naturally around the fold portion 8, so that the outer case 17 can be opened automatically.

[0099] As a result, in this stored item protective box 15, when the first exterior lower surface 22a and the second exterior lower surface 23a are placed on the placement surface T with the front case member 22 and the rear case member 23 in a closed state, the front case member 22 and the rear case member 23 are naturally rotated about the fold 8, and the exterior case 17 can be automatically opened. In this case, when the fold 8 is displaced upward to open the front case member 22 and the rear case member 23, the front case member 22 can be rotated about the boundary between the first exterior lower surface 22a and the first exterior inclined surface 22b as fulcrum P3, and the rear case member 23 can be rotated about the boundary between the second exterior lower surface 23a and the second exterior inclined surface 23b as fulcrum P4.

[0100] In this case, in this storage item protective box 15, the storage case 16 has a first storage slope 16b and a second storage slope 16c on both sides of the storage bottom surface 16a in the opening direction, a first spacer member 24 is arranged on the first storage slope 16b, and a second spacer member 25 is arranged on the second storage slope 16c, and in the open state, the fold portion 8 fits between the first spacer member 24 and the second spacer member 25, allowing the outer case 17 to be opened and closed reliably and smoothly. In other words, the first spacer member 24 and the second spacer member 25 can provide gaps between the first exterior bottom surface 22ab and the second exterior bottom surface 23a of the outer case 17 and the storage bottom surface 16a of the storage case 16, into which the fold portion 8 fits.

[0101] Furthermore, this storage item protection box 15 has a first connecting member 26 that rotatably connects the first spacer member 24 to the inner surface of the first exterior inclined surface 22b, and a second connecting member 27 that rotatably connects the second spacer member 25 to the inner surface of the second exterior inclined surface 23b. Therefore, whether the exterior case 17 is in a closed state or an open state, the storage case 16 can be reliably and satisfactorily supported in a stable state without tilting or moving within the exterior case 17.

[0102] In other words, in this stored item protection box 15, the first connecting member 26 and the second connecting member 27 can support the storage case 16 in an almost horizontal position whether the outer case 17 is in a closed or open position, so that the wristwatch 2 stored in the storage case 16 can be stably and reliably supported in a horizontal position whether the outer case 17 is in a closed or open position.

[0103] (Third embodiment) Next, a third embodiment of a storage item protection box 30 to which the present invention is applied will be described with reference to Figures 9 to 13. Note that the same parts as those in the second embodiment shown in Figures 5 to 8 will be described using the same reference numerals. 9 to 12, the storage item protective box 30 includes a packing member 31 that encases the exterior case 17. The packing member 31 is formed by folding a single sheet member 32, and when the sheet member 32 is unfolded, the exterior case 17 is exposed on the sheet member 32.

[0104] 11 and 12, when unfolded, the sheet member 32 is made of cardboard sandwiched between thin paper, and includes a bottom surface portion 33 that corresponds to the bottom surface of the outer case 17, i.e., the first outer bottom surface 22a of the front case member 22 and the second outer bottom surface 23a of the rear case member 23, a front surface portion 34 that corresponds to the front surface of the front case member 22 in the X-axis direction in FIG. 11, a rear surface portion 35 that corresponds to the rear surface of the rear case member 23 in the X-axis direction in FIG. 11, side surfaces 36 and 37 that respectively correspond to both side surfaces of the outer case 17 in the Z-axis direction in FIG. 11, and an top surface portion 38 that is continuous with the front surface portion 34 and corresponds to the top surface of the outer case 17 in the Y-axis direction in FIG. 11.

[0105] 10 to 13, a foldable flap portion 39 is provided on the edge of the tip of the top surface portion 38. The flap portion 39 is inserted between the rear surface portion 35 and a rear folding portion 42 (described later). The flap portion 39 extends long toward the tip of the top surface portion 38, and this extended portion is folded in half and overlapped. The flap portion 39 is adhered only in the vicinity of both sides of the folding portion by first adhesive regions E1, E2.

[0106] 12 and 13, the flap portion 39 is provided with a finger hook 39a for facilitating the hooking of a finger Y. The finger hook 39a has a semicircular arc-shaped hole, is provided only in the portion of the paper material adjacent to the top surface portion 38, and is closed by the folded-back paper material. In this case, when a finger Y is inserted into the semicircular arc-shaped hole of the finger hook 39a, the unattached inner paper material is pressed by the finger Y and collapses inward.

[0107] 12 and 13, the finger hook 39a is provided with a reinforcing portion 39b in which the paper material in the semicircular hole is folded back and adhered at the second adhesive regions E3 and E4. Furthermore, the front edge of the rear surface portion 35 is provided with a notch 35a that fits into the finger hook 39a when the flap portion 39 is inserted between the rear surface portion 35 and the rear bent portion 42.

[0108] Meanwhile, as shown in Figures 10 to 12, foldable cover surface portions 40, 41 are provided on each side of the tip of each side surface portion 36, 37, and are disposed on the top surface of exterior case 17. Narrow rear surface folding portions 42 are provided on each side on both sides of rear surface portion 35, and narrow rear side surface folding portions 43, 44 are provided on each side of each side surface portion 36, 37 on the rear surface portion 35 side. In this case, by making each rear surface folding portion 42 and each rear side surface folding portion 43, 44 the minimum necessary size, overlapping when folded is reduced, thereby reducing thickness and making folding easier.

[0109] 11 and 12, the rear folding portion 42 and the rear side folding portion 43 are foldably connected. Similarly, the rear folding portion 42 and the rear side folding portion 44 are foldably connected. In this case, the tip of each of the rear side folding portions 43, 44 located on the cover surface portions 40, 41 side is provided with each of inclined portions 43a, 44a to make it easier to insert the flap portion 39 between the rear surface portion 35 and the rear folding portion 42.

[0110] 11 and 12, a wide front folding portion 45 is provided on each side of the front surface 34, and wide front side folding portions 46, 47 are provided on each side of the side surfaces 36, 37 on the front surface 34 side. The wide front folding portion 45 and the front side folding portions 46, 47 increase the return force when the packaging member 31 is opened and the sheet member 32 is unfolded.

[0111] Next, a case where the exterior case 17 of the storage item protection box 15 is wrapped in the packing material 31 will be described. In this case, first, the sheet member 32 of the packaging member 31 is unfolded, and the underside of the outer case 17, i.e., the first outer underside 22a of the front case member 22 and the second outer underside 23a of the rear case member 23, are placed on the underside portion 33 of the sheet member 32.

[0112] In this state, the side portions 36, 37 are folded toward both sides of the exterior case 17. At this time, the narrow rear side folded portions 43, 44 and the wide front side folded portions 46, 47 of the side portions 36, 37 are folded and stand up. At this time, the narrow rear folded portions 42 on both sides of the rear portion 35 and the wide front folded portions 45 on both sides of the front portion 34 are also folded and stand up.

[0113] Then, the front portion 34 is folded toward the front surface of the exterior case 17, i.e., the front surface of the front case member 22, and the rear portion 35 is folded toward the rear surface of the rear case member 23. In this case, when folding the front portion 34, the front bent portions 45 are folded inward relative to both side edges of the front portion 34, and the front side bent portions 46, 47 are folded inward relative to the edges of the side portions 36, 37 on both sides.

[0114] When folding the rear portion 35, the rear folding portions 42 are folded inward relative to both side edges of the rear portion 35, and the rear side folding portions 43, 44 are folded inward relative to the edges of the side portions 36, 37 on both sides. As a result, the bottom, front, rear, and both side surfaces of the exterior case 17 are covered with the sheet member 32, except for the top surface of the exterior case 17, as shown in FIG.

[0115] In this state, the cover surfaces 40, 41 of the side surfaces 36, 37 on both sides are placed on the top surface of the outer case 17, and the top surface 38 is folded and placed on the top surface of the outer case 17. Then, the flap portion 39 at the tip of the top surface 38 is inserted between the rear surface 35 and the rear folded portion 42. As a result, the outer case 17 is wrapped in the sheet member 32, and the outer case 17 is packaged in the packaging member 31. In this state, as shown in FIG. 9 , the finger hook portion 39a of the flap portion 39 is exposed in correspondence with the notch 35a provided on the upper edge of the rear surface 35.

[0116] Next, the case of opening the packaging member 31 that packs the exterior case 17 will be described. In this case, a finger Y is inserted into the finger hook 39a of the flap portion 39 that corresponds to the notch 35a of the rear surface portion 35 and pushed up. When the finger Y is inserted into the finger hook 39a, the unbonded inner paper material is pressed by the finger Y and collapses inward, as shown in FIG. 13(b). Therefore, as shown in FIG. 9, the finger Y is inserted into the finger hook 39a, and the flap portion 39 can be easily pushed up and removed from between the rear surface portion 35 and the rear folding portion 42.

[0117] This allows the sheet member 32 of the packaging member 31 to unfold. In this case, by pushing up the top surface portion 38 and causing it to stand up, and by pushing up and causing the cover surface portions 40 and 41 to stand up, the top surface of the outer case 17 is exposed. In this state, by tilting the front surface portion 34 forward, the rear surface portion 35 backward, and the side surface portions 36 and 37 on both sides to the side, the outer case 17 is released from being wrapped in the sheet member 32.

[0118] This exposes the exterior case 17 above the sheet member 32, and the exterior case 17 enters an open state, similar to the second embodiment. At this time, similar to the second embodiment, the front case member 22 and rear case member 23 of the exterior case 17 naturally rotate around the fold 8, automatically entering an open state, and automatically exposing the wristwatch 2 stored in the internal storage case 16.

[0119] Thus, this storage item protection box 30 has the same effects as the second embodiment, and is equipped with a packaging material 31 that encases the outer case 17. This packaging material 31 is made by folding a single sheet member 32, and when this sheet member 32 is unfolded, the outer case 17 is exposed on the sheet member 32, so that the outer case 17 can be easily enclosed by simply folding the single sheet member 32, and the packaging of the outer case 17 can be easily released by simply unfolding the single sheet member 32.

[0120] In addition, in this storage item protection box 30, the sheet member 32 is unfolded and the exterior is placed on the sheet member 32. When the case 17 is exposed, the outer case 17 is opened, so that the sheet member 32 can be unfolded with a movement like a flower opening, and the front case member 22 and the rear case member 23 of the outer case 17 can be automatically opened, so that an excellent design can be provided.

[0121] In the above-described third embodiment, the case where the outer case 17 of the second embodiment is wrapped in the sheet member 32 of the packing member 31 is described, but the present invention is not limited to this, and for example, the outer case 4 of the first embodiment may be wrapped in the sheet member 32.

[0122] Furthermore, in the above-described first to third embodiments, the item stored in the storage case 3, 16 is described as a wristwatch 2, but this invention does not necessarily have to be a wristwatch 2, and it could be, for example, a gemstone such as a diamond, ruby, pearl, or a precious metal such as a ring; in short, any item that can be stored in the storage case 3, 16 is acceptable.
