DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments and modifications of the present invention will be described with reference to the accompanying drawings. Note that the dimensional proportions in the drawings are exaggerated for the sake of explanation and differ from the actual proportions.

[0009] 1 and 2 are perspective views showing the toothbrush set 1. FIG. 1 is a perspective view showing a state in which the opening 115 of the case member 110 is closed by the cover member 120, and FIG. 2 is a perspective view showing a state in which the opening 115 of the case member 110 is open. FIG. 3 is a perspective view showing the storage case 10. FIG. 3 shows a state in which the opening 115 of the case member 110 is open. FIG. 4 is a front view showing the storage case 10. FIG. 4 shows a state in which the opening 115 of the case member 110 is open. FIG. 5 is a top view of the case main body 100. FIGS. 6 and 7 are perspective views showing enlarged portions of the case main body 100.

[0010] Arrows X1-X2 shown in each drawing indicate the longitudinal direction of case body 100, arrows Y1-Y2 indicate the width direction (short side direction) of case body 100, and arrows Z1-Z2 indicate the depth direction of case body 100. The longitudinal direction of storage case 10, the longitudinal direction of case member 110, and the longitudinal direction of cover member 120 are substantially the same direction as the longitudinal direction of case body 100.

[0011] As shown in FIG. 1, the toothbrush set 1 of the first modified example includes a storage case 10, a toothbrush 300, and a container (hereinafter simply referred to as "container") 400 that stores a mouthwash.

[0012] Toothbrush 300 has a head portion provided with bristles, a handle portion that can be held by the user with the fingers, and a neck portion that connects the head portion and the handle portion. The specific configuration of toothbrush 300 is not particularly limited, and toothbrushes with the same configuration as known toothbrushes can be used.

[0013] The storage case 10 includes a case body 100 and a cap 200 .

[0014] The case body 100 has a case member 110 having a first space 113 and an opening 115, and a cover member 120.

[0015] 4, the case member 110 has a half-split cylindrical shape extending along the longitudinal direction. A lid member 120 is connected to one end of the case member 110 in the width direction (the end indicated by the arrow Y2) via hinge portions 131 and 132, which will be described later.

[0016] First space 113 can accommodate part 301 of toothbrush 300 and container 400. First space 113 is formed inside case member 110. Part 301 of toothbrush 300 accommodated in first space 113 is any part including, for example, the handle portion of toothbrush 300 and its surrounding area.

[0017] Case member 110 may be provided with partition plate 190 that separates first space 113 into an area for accommodating toothbrush 300 and an area for accommodating container 400. Case member 110 may also be provided with cap holding portion 181 into which a portion of the cap of container 400 can be fitted.

[0018] Opening 115 allows toothbrush 300 and container 400 to be removed from first space 113. Opening 115 is formed over substantially the entire length of case member 110. As shown in FIG. 4, opening 115 has a substantially rectangular planar shape.

[0019] The longitudinal dimension of opening 115 can be, for example, 85% or more and 96% or less of the total longitudinal length of case body 100 (the total longitudinal length of case body 100 including cap attachment portion 150, which will be described later). By setting the longitudinal dimension of opening 115 to such a length, toothbrush 300 can be easily inserted and removed from first space 113 through opening 115 even when cap 200 is attached to case body 100.

[0020] The case body 100 has an outer shape of a roughly triangular prism when the opening 115 is closed by the lid member 120. The bottom surface of the case body 100 has a roughly triangular planar shape. A user can place the storage case 10 upright by placing the bottom surface of the case body 100 on a desk or the like. This allows the case body 100 to be stored in a smaller space. Furthermore, because the case body 100 has a roughly triangular prism shape, the storage case 10 can be prevented from rolling even when placed sideways on a desk or the like.

[0021] Lid member 120 is configured to be able to open and close opening 115. A space 123 is formed inside lid member 120. When opening 115 is closed by lid member 120, joining surface S1 formed on the periphery of case member 110 and joining surface S2 formed on the periphery of lid member 120 are arranged to face each other. Furthermore, when opening 115 is closed by lid member 120, removal of toothbrush 300 and container 400 from opening 115 is restricted.

[0022] The cap 200 is detachably attached to the case body 100 at one end in the longitudinal direction of the case body 100 (the end located in the direction indicated by the arrow X1).

[0023] When attached to the case body 100, the cap 200 has a second space 203 that can accommodate a portion 302 of the toothbrush 300 that is different from the portion 301 accommodated in the first space 113. The portion 302 of the toothbrush 300 accommodated in the second space 203 is, for example, any portion including the head portion of the toothbrush 300 and its surrounding area.

[0024] As shown in FIG. 2, in the storage case 10, the opening 115 can be opened and closed by the lid member 120 when the cap 200 is attached to the case body 100.

[0025] As shown in Figures 2 and 3, the cap 200 can be attached to and detached from the case body 100 by moving it relatively close to or away from one end of the case body 100 in the longitudinal direction of the case body 100.

[0026] The cap 200 can be attached to the case body 100 by moving it in a direction toward the case body 100 (moving it in the direction indicated by the arrow A1 in FIG. 3). Furthermore, the cap 200 can be removed from the case body 100 by moving it away from the case body 100 (moving it in the direction indicated by the arrow A2 in FIG. 3) while it is attached to the case body 100.

[0027] The opening 115 of the lid member 120 can be opened and closed by moving at least a portion of the lid member 120 relatively closer to or farther away from the case member 110 in a direction intersecting the longitudinal direction of the case body 100. The direction intersecting the longitudinal direction of the case body 100 is, for example, the width direction, the depth direction, or a direction around an axis that is an axis along the longitudinal direction of the case body 100 and serves as a rotation axis D (see FIG. 3).

[0028] As shown in FIGS. 3 and 4, the storage case 10 has hinge portions 131 and 132 and a lock portion 140.

[0029] Hinge portions 131 and 132 connect case member 110 and lid member 120, and allow lid member 120 to open and close opening 115 in response to a rotation operation. Lock portion 140 maintains opening 115 closed by lid member 120. The rotation direction of hinge portions 131 and 132 is indicated by arrows R1-R2 in Figures 2 and 3. In this modification, opening 115 can be opened and closed by lid member 120 by rotating hinge portions 131 and 132 around rotation axis D that extends along the longitudinal direction of case body 100.

[0030] Hinge sections 131 and 132 are arranged with a predetermined gap between them along the longitudinal direction of case member 110. Hinge sections 131 and 132 can be configured integrally with case member 110 and lid member 120, for example. Alternatively, the hinge sections may be assembled to case main body 100 by separately attaching a hinge structure having a rotatable shaft and bearings to case member 110 and lid member 120, for example. Furthermore, the number of hinge sections provided in case main body 100 is not particularly limited.

[0031] The structure for opening and closing lid member 120 is not limited to hinge portions 131 and 132. For example, lid member 120 may be configured to be able to open and close opening 115 by an operation such as sliding lid member 120 toward the other end of case member 110 in the longitudinal direction (the end located in the direction indicated by arrow X2), sliding lid member 120 in the width direction of case member 110, or lifting lid member 120 in a direction away from opening 115 of case member 110.

[0032] As shown in Figures 3 and 4, the lid member 120 can be provided with a regulating portion 182 that presses down on the container 400 contained in the first space portion 113 when the opening 115 is closed by the lid member 120, thereby regulating the movement of the container 400 within the first space portion 113.

[0033] 3 and 4, the locking portion 140 has a fitting hole 141 provided in the case member (corresponding to the "one member") 110 and a protrusion 143 provided in the cover member (corresponding to the "other member") 120. The protrusion 143 can be fitted into and released from the fitting hole 141.

[0034] The fitting hole 141 is provided near the approximate center in the longitudinal direction of the case member 110. The fitting hole 141 extends a predetermined length along the longitudinal direction of the case member 110. The fitting hole 141 is formed near the periphery of the opening 115 of the case member 110.

[0035] Protrusion 143 is disposed on cover member 120 in a position corresponding to the installation position of fitting hole 141 of case member 110. Protrusion 143 is provided near the approximate center of cover member 120 in the longitudinal direction.

[0036] Fitting hole 141 may be provided in at least one of case member 110 and lid member 120. For example, fitting hole 141 may be provided in both case member 110 and lid member 120, or only lid member 120. Protrusion 143 may be provided in at least one of case member 110 and lid member 120 in correspondence with fitting hole 141. Therefore, protrusion 143 may be provided in both case member 110 and lid member 120, or only case member 110, similar to fitting hole 141.

[0037] 7, protrusion 143 has hook portion 143a. When opening 115 is closed by lid member 120, hook portion 143a is fitted into fitting hole 141 so as to wrap around the outer surface side of case member 110.

[0038] The tip of hook portion 143a in the protruding direction is curved toward the inner surface of cover member 120. Hook portion 143a is inserted into fitting hole 141 and hooked onto fitting hole 141 when opening 115 is closed by cover member 120.

[0039] The specific shape of protrusion 143 is not limited as long as it can be fitted into fitting hole 141. Protrusion 143 may have, for example, a simple convex shape (a conical shape or a cylindrical shape) that can be fitted into fitting hole 141.

[0040] The specific configuration of locking section 140 is not particularly limited as long as it can maintain the state in which lid member 120 closes opening 115. Locking section 140 may be configured, for example, by a mechanical locking mechanism that fits a recessed portion and a protruding portion together, a locking mechanism that uses a magnetic member such as a magnet, or a locking mechanism that uses an adhesive member.

[0041] As shown in FIG. 7, the cover member 120 has fitting ribs 145a and 145b that sandwich the wall of the case member 110 between the hook portion 143a and the fitting ribs 145a and 145b when the hook portion 143a is fitted into the fitting hole 141.

[0042] The fitting ribs 145a and 145b are arranged at different positions in the longitudinal direction of the cover member 120, with the protrusion 143 sandwiched between them. The fitting ribs 145a and 145b protrude outward from the inner surface 121 of the cover member 120. When the opening 115 is closed by the cover member 120, the hook portion 143a wraps around from the outside of the case member 110 and is inserted into the fitting hole 141. When the opening 115 is closed by the cover member 120, the fitting ribs 145a and 145b abut against the inner surface 111 of the case member 110. The wall portion located near the fitting hole 141 of the case member 110 is sandwiched between the hook portion 143a, which wraps around and is arranged on the outer surface side of the case member 110, and the fitting ribs 145a and 145b, which are arranged on the inner surface side of the case member 110.

[0043] As shown in Fig. 7, the lid member 120 has a blind portion 128. When the protrusion 143 is fitted into the fitting hole 141 and the opening 115 is closed by the lid member 120, as shown in Fig. 1, the blind portion 128 extends toward the case member 110 beyond the joining surface S1 of the case member 110 and the joining surface S2 of the lid member 120, and covers the fitting hole 141 and the protrusion 143.

[0044] The blinding portion 128 is provided approximately near the center in the longitudinal direction of the lid member 120. The blinding portion 128 is formed by extending a part of the lid member 120 from both ends in the longitudinal direction of the lid member 120 toward the center, in a direction away from the inner surface 121 of the lid member 120. A protrusion 143 is arranged on the inside of the blinding portion 128.

[0045] When the opening 115 is closed by the lid member 120, the case body 100 has a skirt shape in which the approximate center position in the longitudinal direction where the blind portion 128 is formed bulges in the width direction and the width gradually narrows from the approximate center position in the longitudinal direction toward both ends in the longitudinal direction.

[0046] The shape of blinding portion 128 and the position where blinding portion 128 is provided are not particularly limited as long as it can cover fitting hole 141 and protrusion 143 when opening 115 is closed by lid member 120. Furthermore, blinding portion 128 can be provided on either case member 110 or lid member 120, whichever member has protrusion 143 provided thereon. For example, when protrusion 143 is provided on case member 110 and fitting hole 141 is provided on lid member 120, blinding portion 128 can be provided on case member 110.

[0047] As shown in FIGS. 3 and 4, the case member 110 has first ribs 117a and 117b.

[0048] The first rib 117a is disposed at one longitudinal end (the end located in the direction indicated by the arrow X1) of the case member 110. The first rib 117a protrudes from the inner surface 111 of the case member 110. Of both corners 110a and 110b located at one end of the case member 110, the first rib 117a is disposed at the corner 110a located on the side away from the hinge portions 131 and 132 in the width direction of the case member 110.

[0049] The first rib 117b is disposed at the other longitudinal end (the end located in the direction indicated by the arrow X2) of the case member 110. The first rib 117b protrudes from the inner surface 111 of the case member 110. Of both corners 110c and 110d located at the other end of the case member 110, the first rib 117b is disposed at the corner 110c located on the side away from the hinge portions 131 and 132 in the width direction of the case member 110.

[0050] 4, the first rib 117a has a generally L-shaped planar shape extending along a corner 110a of the case member 110. The first rib 117b has a generally L-shaped planar shape extending along a corner 110c of the case member 110.

[0051] As shown in FIGS. 3 and 4, the cover member 120 has second ribs 127a and 127b.

[0052] Second rib 127a is located at one longitudinal end of lid member 120 (the end located in the direction indicated by arrow X1) corresponding to the installation position of first rib 117a. Second rib 127a protrudes from inner surface 121 of lid member 120. Of both corners 120a, 120b located at one end of lid member 120, second rib 127a is located at corner 120a located on the side away from hinge portions 131, 132 in the width direction of lid member 120.

[0053] Second rib 127b is located at the other longitudinal end (the end in the direction indicated by arrow X2) of lid member 120, corresponding to the installation position of first rib 117b. Second rib 127b protrudes from inner surface 121 of lid member 120. Of both corners 120c, 120d located at the other end of lid member 120, second rib 127b is located at corner 120c located on the side away from hinge portions 131, 132 in the width direction of lid member 120.

[0054] A gap g1 is provided between the inner surface 121 of the cover member 120 and the second rib 127a. The first rib 117a can fit into the gap g1 when the opening 115 is closed by the cover member 120. The gap g1 has a planar shape corresponding to the planar shape of the first rib 117a. As shown in FIG. 4, the gap g1 has a substantially L-shaped planar shape. The gap g1 is surrounded on all sides by the second rib 127a.

[0055] A gap g2 is provided between the inner surface 121 of the cover member 120 and the second rib 127b. The first rib 117b can fit into the gap g2 when the opening 115 is closed by the cover member 120. The gap g2 has a planar shape corresponding to the planar shape of the first rib 117b. As shown in FIG. 4, the gap g2 has a substantially L-shaped planar shape. The gap g2 is surrounded on all sides by the second rib 127b.

[0056] Gaps g1 and g2 may be provided, for example, in case member 110. In such a configuration, ribs (ribs corresponding to first ribs 117a and 117b) that can fit into the gaps g1 and g2 may be provided on cover member 120.

[0057] When opening 115 is closed by lid member 120, first rib 117a enters gap g1 provided in corner 120a of lid member 120 and is pressed against the inner surface of second rib 127a. Furthermore, when opening 115 is closed by lid member 120, first rib 117b enters gap g2 provided in corner 120c of lid member 120 and is pressed against the inner surface of second rib 127b.

[0058] The positions of the gaps g1, g2 provided in the case member 110 or the lid member 120 are not particularly limited, as long as they are at the longitudinal end of the case member 110 or the longitudinal end of the lid member 120. Similarly, the positions of the ribs that can fit into the gaps in the case member 110 or the lid member 120 are not particularly limited, as long as they correspond to the gaps. Furthermore, the number and shape of the gaps are not particularly limited. The number and shape of the ribs that form the gaps and the ribs that can fit into the gaps are also not particularly limited.

[0059] As shown in FIG. 4, the case member 110 has auxiliary ribs 118a and 118b.

[0060] The auxiliary rib 118a is disposed at one end in the longitudinal direction of the case member 110. The auxiliary rib 118a protrudes from the inner surface 111 of the case member 110. Of both corners 110a, 110b located at one end of the case member 110, the auxiliary rib 118a is disposed at the corner 110b located on the hinge portions 131, 132 side in the width direction of the case member 110.

[0061] Auxiliary rib 118b is disposed at the other longitudinal end of case member 110. Auxiliary rib 118b protrudes from inner surface 111 of case member 110. Of both corners 110c, 110d located at the other end of case member 110, auxiliary rib 118b is disposed at corner 110d located on the hinge portions 131, 132 side in the width direction of case member 110.

[0062] As shown in Fig. 4, the auxiliary rib 118a has a generally L-shaped planar shape extending along the corner 110b of the case member 110. As shown in Fig. 4, the auxiliary rib 118b has a generally L-shaped planar shape extending along the corner 110d of the case member 110.

[0063] Auxiliary rib 118a comes into contact with the inner surface of corner 120b of lid member 120 when opening 115 is closed by lid member 120. Furthermore, auxiliary rib 118b comes into contact with the inner surface of corner 120d of lid member 120 when opening 115 is closed by lid member 120.

[0064] The auxiliary ribs 118a, 118b may be provided, for example, on the lid member 120. Furthermore, the auxiliary ribs 118a, 118b may be provided on both the case member 110 and the lid member 120. Furthermore, the positions and numbers of the auxiliary ribs 118a, 118b on the case member 110 and the lid member 120 are not particularly limited.

[0065] In this modified example, the first ribs 117a, 117b are arranged at the corners 110a, 110c located on the side spaced apart in the width direction of the case member 110 from the hinge portions 131, 132. The second ribs 127a, 127b are arranged at the corners 120a, 120c located on the side spaced apart in the width direction of the cover member 120 from the hinge portions 131, 132. On the other hand, the auxiliary ribs 118a, 118b are arranged at the corners 110b, 110d located on the side of the hinge portions 131, 132 in the width direction of the case member 110. This is for the following reason.

[0066] Corners 110a, 110c, 120a, and 120c of case member 110 and lid member 120 that are located on the side away from hinge portions 131 and 132 in the width direction are distant from rotation axis D of hinge portions 131 and 132 and the connection position between case member 110 and lid member 120. Therefore, corners 110a and 110c located on the mating hole 141 side of case member 110 and corners 120a and 120c located on the protrusion 143 side of lid member 120 are prone to misalignment when mating case member 110 and lid member 120. Furthermore, at corners 110a, 110c, 120a, and 120c, if an external impact is applied to storage case 10 while opening 115 is closed by lid member 120, the mated state may be easily released. On the other hand, corners 110b, 110d located on the hinge portions 131, 132 side of case member 110 and corners 120b, 120d located on the hinge portions 131, 132 side of lid member 120 are located in proximity to rotation axis D when lid member 120 is opened and closed, so misalignment is unlikely to occur when case member 110 and lid member 120 are mated, and because they are also close to the connection position between case member 110 and lid member 120, the mated state is unlikely to be released even if an external force is applied to storage case 10. Therefore, in this modification, first ribs 117a, 117b that can generate a greater mating force are arranged at each corner 110a, 110c of case body 100, and similarly, second ribs 127a, 127b that can generate a greater mating force are arranged at each corner 120a, 120c of lid member 120. On the other hand, in order to reinforce the mating force between the case member 110 and the cover member 120, auxiliary ribs 118a, 118b that generate a mating force smaller than that of each of the ribs 117a, 117b, 127a, 127b are arranged at each corner 110b, 110d located on the hinge portion 131, 132 side of the case member 110.

[0067] The case member 110 has a cap attachment portion 150 as shown in FIGS.

[0068] The cap attachment portion 150 is provided at one end in the longitudinal direction of the case member 110. The cap attachment portion 150 protrudes in the longitudinal direction of the case member 110. The cap 200 can be fitted into the cap attachment portion 150.

[0069] As shown in Figure 2, a third space 153 is formed inside the cap attachment portion 150, which can accommodate at least a portion of a part 302 different from the part 301 accommodated in the first space 113 of the toothbrush 300 together with the second space 203 when the cap 200 is fitted to the cap attachment portion 150.

[0070] The third space 153 is disposed inside the second space 203 when the cap 200 is fitted to the cap attachment part 150. A notch can be provided in a part of the circumferential direction of the cap attachment part 150 to promote elastic deformation of the cap attachment part 150 when attaching or detaching the cap 200. In addition, a rib can be provided on the outer peripheral surface of the cap attachment part 150 to increase the fixing force of the cap 200 to the cap attachment part 150.

[0071] As shown in Figures 5 and 6, case member 110 and cover member 120 have partition wall 160. As shown in Figures 1 and 5, partition wall 160 separates first space 113 and third space 153 when opening 115 is closed by cover member 120.

[0072] As shown in FIG. 5, the partition wall 160 has a first wall portion 161 provided on the case member 110 and a second wall portion 162 provided on the cover member 120.

[0073] When the opening 115 is closed by the cover member 120, the first wall portion 161 and the second wall portion 162 abut against each other and become one body, thereby forming a wall portion that separates the first space portion 113 and the third space portion 153.

[0074] As shown in FIG. 5, the partition wall 160 is formed with a communication section 170 that connects the first space section 113 and the third space section 153 to each other.

[0075] As shown in FIG. 5 , the communication portion 170 has a first recess 171 formed in a portion of the first wall portion 161 and a second recess 172 formed in a portion of the second wall portion 162. The first recess 171 and the second recess 172 are arranged opposite each other when the opening 115 is closed by the cover member 120. When the first recess 171 and the second recess 172 are arranged opposite each other, they form a hole that communicates between the first space 113 and the third space 153. As shown in FIGS. 1 and 2 , when the toothbrush 300 is stored in the storage case 10, a portion 302 of the toothbrush 300 on the neck side can be accommodated in the second space 203 and the third space 153 through the communication portion 170.

[0076] The communication portion 170 may be configured as a through-hole provided in only one of the first wall portion 161 and the second wall portion 162, for example. However, if the communication portion 170 is configured as a through-hole, when storing the portion 302 of the toothbrush 300 in the third space portion 153, a portion of the toothbrush 300 (e.g., the neck portion) must be inserted into the through-hole. This reduces the ease of storing the toothbrush 300. On the other hand, if the communication portion 170 is configured as a recess (the first recess 71 or the second recess 172), when storing the portion 302 of the toothbrush 300 in the third space portion 153, the toothbrush 300 can be stored by simply placing the toothbrush 300 in the recess. Furthermore, by placing the toothbrush 300 in the recess, the storage orientation of the toothbrush 300 can be determined by the recess. Furthermore, when toothbrush 300 is placed in the recess, a portion of toothbrush 300 (for example, the neck portion) is held in a floating state, separated from inner surface 111 of case member 110. This makes it easier for the user to grasp the portion of toothbrush 300 from the neck portion to the handle portion with their fingers. This makes it easier to remove toothbrush 300 from case member 110. Therefore, it is preferable that communication portion 170 be formed as a recess rather than a through-hole.

[0077] Partition wall 160 may be provided, for example, on only one of case member 110 and lid member 120. In such a configuration, partition wall 160 may be formed as a single wall arranged to protrude from case member 110 toward lid member 120, or may be formed as a single wall arranged to protrude from lid member 120 toward case member 110. Furthermore, when partition wall 160 is provided on only one of case member 110 and lid member 120, communication portion 170 may be formed, for example, as a through-hole that penetrates partition wall 160 and communicates first space 113 with third space 153.

[0078] Since the case member 110 has the first wall portion 161 provided in a position close to the cap attachment portion 150, excessive elastic deformation of the cap attachment portion 150 can be suppressed when fitting the cap 200 to the cap attachment portion 150 and when removing the cap 200 from the cap attachment portion 150. This allows the user to smoothly attach and detach the cap 200 to and from the cap attachment portion 150.

[0079] In addition, when the partition wall 160 is provided only on the lid member 120 and is positioned so as to protrude from the lid member 120 toward the case member 110, when the opening 115 is closed by the lid member 120, the partition wall 160 abuts against the inner surface 111 of the case member 110, thereby suppressing excessive elastic deformation of the cap attachment portion 150 in the same manner as described above. However, the above effect is further enhanced when the partition wall 160 is provided integrally on the case member 110 side. Therefore, when the partition wall 160 is provided in the storage case 10, it is preferable that the partition wall 160 be provided at least on the case member 110.

[0080] For example, in addition to the communication portion 170, the partition wall 160 can be provided with a through hole so that accessories other than the toothbrush 300 (such as an interdental brush) can be accommodated in the first space portion 113, the second space portion 203, and the third space portion 153.

[0081] In the storage case 10, a portion 302 of the toothbrush 300 is accommodated in the second space 203 of the cap 200. Therefore, the longitudinal dimension of the case member 110 can be made smaller than when the case member 110 is configured to accommodate the toothbrush 300 only in the first space 113 of the case member 110. Furthermore, when the cap 200 is attached to the cap attachment portion 150, the second space 203 and the third space 153 partially overlap in the longitudinal direction of the storage case 10. Therefore, the overall longitudinal length of the storage case 10 can be made smaller than when a structure is adopted in which the cap 200 is attached and detached at a position closer to one end of the storage case 10 in the longitudinal direction than the cap attachment portion 150.

[0082] When cap 200 is removed from case body 100, it can hold a liquid in second space 203. For example, a user can hold water in second space 203. The user can use the water held in second space 203 to rinse the inside of the mouth after brushing their teeth with toothbrush 300.

[0083] The case body 100 (case member 110 and lid member 120) can be made of, for example, a resin material. When the case body 100 is made of a resin material, the resin material can be colored to provide opacity. Furthermore, when the case body 100 is made of a resin material, an antibacterial agent can be incorporated into the resin material. Examples of resin materials that can be used include polypropylene and polyethylene. Examples of antibacterial agents that can be used include silver-based soluble glass antibacterial agents, silver-based glass antibacterial agents, zinc-based soluble glass antibacterial agents, and silver-based zirconium phosphate antibacterial agents. When the case body 100 is opaque, the toothbrushes 300 and containers 400 housed in the storage case 10 are less visible from outside the storage case 10. This prevents the appearance of the storage case 10 from becoming unattractive when carrying the storage case 10, for example. Furthermore, when the case member 110 and the lid member 120 are made of an antibacterial material, the user can use the toothbrush set 1 hygienically for a long period of time. The case member 110 and the cover member 120 may be made of different materials, and may be colored differently.

[0084] The cap 200 can be formed, for example, from the same material as the case body 100. The cap 200 can be configured to be opaque. Furthermore, an antibacterial agent can be kneaded into the resin material that forms the cap 200.

[0085] Next, the effects of this modification will be described.

[0086] 2, in storage case 10 according to this modification, opening and closing of opening 115 for inserting and removing toothbrush 300 and container 400 can be performed with cap 200 attached to case body 100. Therefore, the user does not need to remove cap 200 from case body 100 when inserting and removing toothbrush 300 and container 400 from case body 100. Therefore, storage case 10 can suppress the decrease in convenience that may occur when removing cap 200 from case body 100 when opening and closing opening 115.

[0087] The cap 200 can be attached to or detached from the case body 100 by moving the cap 200 toward or away from one end of the case body 100 along the longitudinal direction of the case body 100. The lid member 120 can open or close the opening 115 by moving at least a portion of the lid member 120 toward or away from the case member 110 in a direction intersecting the longitudinal direction of the case body 100. With this configuration, a user can attach or detach the cap 200 to or from the case body 100 by a simple operation of moving the cap 200 toward or away from one end of the case body 100 in the longitudinal direction. The operation for attaching or detaching the cap 200 is performed at one end of the case body 100 along the longitudinal direction of the case body 100. On the other hand, when opening or closing the opening 115, the lid member 120 is operated in a direction intersecting the longitudinal direction of the case body 100. Therefore, the opening 115 can be easily opened and closed without causing interference between the cover member 120 and the cap 200.

[0088] Storage case 10 has hinge portions 131 and 132 that connect case member 110 and lid member 120 and enable lid member 120 to open and close opening 115 in response to a rotational operation, and lock portion 140 that maintains opening 115 closed by lid member 120. With this configuration, a user can open and close opening 115 with the simple action of rotating lid member 120. Lock portion 140 also allows the user to conveniently maintain opening 115 closed by lid member 120. Even when lid member 120 opens opening 115, hinge portions 131 and 132 allow the user to maintain lid member 120 connected to case member 110. Therefore, when opening 115 is open, the user can avoid the hassle of placing lid member 120 on a nearby desk or sink or storing lid member 120 to prevent it from getting lost.

[0089] Locking section 140 has a fitting hole 141 provided in case member 110 and a protrusion 143 provided in lid member 120 that can be fitted into and released from fitting hole 141. With this configuration, a user can close opening 115 with lid member 120, thereby fitting protrusion 143 provided on lid member 120 into fitting hole 141 provided in case member 110, thereby locking opening 115 in a closed state. Since a user can simultaneously perform the operation to close lid member 120 and the operation to lock lid member 120, the convenience of storage case 10 is improved. Furthermore, when releasing the lock provided by locking section 140, a user moves lid member 120 relatively away from case member 110 and removes protrusion 143 from fitting hole 141. Therefore, when the user releases the lock by locking section 140, there is no need to perform an operation such as twisting lid member 120 relative to case member 110, and lid member 120 can be opened smoothly.

[0090] Protrusion 143 has hook portion 143a that wraps around the outer surface of case member 110 and fits into fitting hole 141. Lid member 120 has fitting ribs 145a, 145b that sandwich a wall portion of case member 110 between hook portion 143a and lid member 120 when hook portion 143a is fitted into fitting hole 141. With this configuration, fitting of hook portion 143a into fitting hole 141 can improve the fitting strength. Furthermore, by sandwiching the wall portion of case member 110 between hook portion 143a and fitting ribs 145a, 145b, it is possible to prevent lid member 120 from floating up from case member 110 and forming a gap when opening 115 is closed by lid member 120.

[0091] The cover member 120 has a blind portion 128 that extends toward the case member 110 beyond the mating surface S1 of the case member 110 and the mating surface S2 of the cover member 120 to cover the mating hole 141 and the protrusion 143 when the opening 115 is closed by the cover member 120 with the protrusion 143 mated in the mating hole 141. With this configuration, the mating hole 141 and the protrusion 143 can be prevented from being exposed to the outside when the opening 115 is closed by the cover member 120. This prevents the appearance of the storage case 10 from being impaired. Furthermore, when a user carries the storage case 10, the mating hole 141 and the protrusion 143 can be prevented from coming into contact with the user's fingers, etc., causing discomfort to the user.

[0092] Case member 110 has first ribs 117a, 117b disposed at at least one longitudinal end of case member 110 and protruding from inner surface 111 of case member 110. Lid member 120 has second ribs 127a, 127b disposed at at least one longitudinal end of lid member 120 corresponding to the positions of first ribs 117a, 117b and protruding from inner surface 121 of lid member 120. Gaps g1, g2 are provided between inner surface 121 of lid member 120 and second ribs 127a, 127b, into which first ribs 117a, 117b can fit when opening 115 is closed by lid member 120. With this configuration, when opening 115 is closed by lid member 120, first ribs 117a, 117b are inserted into and fitted into gaps g1, g2, respectively. Therefore, the fitting force between case member 110 and cover member 120 can be increased, and cover member 120 can be effectively prevented from opening accidentally.

[0093] One longitudinal end of case member 110 is provided with cap attachment portion 150 that protrudes in the longitudinal direction of case member 110 and into which cap 200 can be fitted. A third space 153 is formed inside cap attachment portion 150. When cap 200 is fitted into cap attachment portion 150, third space 153 can accommodate at least a part of portion 302 of toothbrush 300 that is different from the portion accommodated in first space 113, together with second space 203. Case member 110 and cover member 120 have partition wall 160 that separates first space 113 from third space 153 when opening 115 is closed by cover member 120. Partition wall 160 has a communication portion 170 that communicates first space 113 with third space 153. With this configuration, with part 301 of toothbrush 300 accommodated in first space 113, communication portion 170 allows other part 302 of toothbrush 300 to be accommodated in second space 203 and third space 153. In addition, partition wall 160 can increase the strength of case member 110 near the boundary between first space 113 and third space 153.

[0094] When the cap 200 is removed from the case body 100, it can hold liquid in the second space 203. With this configuration, the user can use the cap 200 as a cup when brushing their teeth. This further improves the convenience of the storage case 10.

[0095] Toothbrush set 1 includes storage case 10, toothbrush 300 that can be stored in storage case 10, and container 400 that can be stored in storage case 10. This configuration makes it possible to provide toothbrush set 1 that minimizes the decrease in convenience that can occur when cap 200 is removed from case body 100 when opening and closing opening 115.

[0096] <Example> The present invention will be described below based on examples, but the present invention is not limited to the following examples. In the description of the examples, the names of the components described in the above-mentioned modified examples will be used. Example 1 As Example 1, a storage case having the following configurations 1 and 2 was prepared. Configuration 1: Removable cap Configuration 2: A lid member that can open and close the opening with the cap attached (Evaluation items) In Example 1, evaluation tests were carried out for the following evaluation items 1 and 2. Evaluation item 1: Ease of removing the toothbrush from the first space Evaluation item 2: Ease of cap removal (Comparative Example 1) As Comparative Example 1, a storage case having the configuration shown in Table 1 was prepared. The storage case of Comparative Example 1 has a structure that allows toothbrushes to be inserted and removed from one end of the storage case in the longitudinal direction by removing the cap.

[0097] In the evaluation test, a panel of 10 experts used the storage cases of Example 1 and Comparative Example 1 and evaluated them according to the following evaluation criteria. Each expert panel performed the evaluation test 10 times. The evaluation score was the average score of the 10 evaluation tests. (Evaluation criteria) 7 points: Very good. 6 points: Quite good. 5 points: Fairly good. 4 points: Can't say either way. 3 points: Not very good. 2 points: Not very good. 1 point: Very poor.

[0098] [Table 1]

[0099] As shown in Table 1, the storage case of Example 1 received higher evaluation scores for evaluation item 1 (ease of removing the toothbrush from the first space) and evaluation item 2 (ease of removing the cap) than Comparative Example 1. In particular, the storage case of Example 1, whose opening can be opened and closed without removing the cap, received a higher evaluation score for evaluation item 1 than the storage case of Comparative Example 1, in which the toothbrush could only be removed with the cap removed. Example 2 As Example 2, a storage case having the following configurations 1 to 3 was prepared. Configuration 1: Removable cap Configuration 2: A lid member that can open and close the opening with the cap attached Configuration 3: Fitting hole, hook part, blind part (Evaluation items) In Example 2, evaluation tests were carried out for the following evaluation items 3 and 4. Evaluation item 3: Appearance Evaluation item 4: Ease of opening and closing the lid (Comparative Example 2) As Comparative Example 2, a storage case having the configuration shown in Table 2 was prepared. The storage case of Comparative Example 2 has a lid member that is unlocked by twisting the lid member relative to the case member. Furthermore, the storage case of Comparative Example 2 does not have a removable cap.

[0100] The evaluation test was carried out by an expert panel in the same manner as in Example 1. The expert panel scored the samples based on the evaluation criteria shown in Example 1.

[0101] [Table 2]

[0102] As shown in Table 2, the storage case of Example 2 received higher evaluation scores for evaluation item 3 (appearance) and evaluation item 4 (ease of opening and closing the lid member) than the storage case of Comparative Example 2. The reason for this is thought to be as follows: The lid member of the storage case of Comparative Example 2 is unlocked by twisting the case member. Therefore, the hook portion for performing the twisting operation is exposed to the outside, resulting in a low evaluation score for evaluation item 3. In contrast, the storage case of Example 2 has the fitting hole and hook portion covered by the blind portion, so the appearance is not impaired, and it received a higher evaluation score for evaluation item 3 than the storage case of Comparative Example 2.

[0103] Furthermore, the cover member of the storage case of Comparative Example 2 is unlocked by twisting the case member, which can be cumbersome for the user when opening the cover member. On the other hand, the storage case of Example 2 can be easily unlocked by pulling the cover member to remove the hook portion from the engagement hole. Therefore, the storage case of Example 2 received a higher score for evaluation item 4 than the storage case of Comparative Example 2. Example 3 As Example 3, a storage case having the following configurations 1 to 5 was prepared. Configuration 1: Removable cap Configuration 2: A lid member that can open and close the opening with the cap attached Configuration 3: Fitting hole, hook part, blind part Configuration 4: Interlocking ribs (Configuration 4 uses the layout and shape shown in Figure 4) Configuration 5: First rib, second rib, gap into which the first rib can fit, auxiliary rib (Configuration 5 adopts the arrangement and shape shown in Figure 4) (Evaluation items) In Example 3, evaluation tests were carried out for the following evaluation item 5. Evaluation item 5: Difficulty in opening the lid when dropped.

[0104] The evaluation test was conducted by an expert panel in the same manner as in Examples 1 and 2. The expert panel dropped the storage case of Example 3 from a height of 20 cm to 60 cm with the lid member closed. If the case did not open when dropped from a height of 60 cm, the result of the evaluation test was rated as ◎; if the case did not open when dropped from a height of 20 cm to 40 cm, it was rated as ○; and if the case opened at a height of less than 20 cm, it was rated as △.

[0105] [Table 3]

[0106] As shown in Table 3, the storage case of Example 3 did not open even when dropped from a height of 60 cm. This is thought to be due in particular to the fact that the fitting force between the case member and the lid member is increased by Structure 5 provided in the storage case of Example 3.

[0107] Next, a toothbrush set 1 and a storage case 10 according to one embodiment will be described with reference to FIGS.

[0108] Arrows X1-X2 shown in each drawing indicate the longitudinal direction of case body 100, arrows Y1-Y2 indicate the lateral (width) direction of case body 100, and arrows Z1-Z2 indicate the depth (depth) direction of case body 100. The longitudinal direction of case member 110 and the longitudinal direction of cover member 120 are substantially the same as the longitudinal direction of case body 100. Furthermore, direction θ shown in each drawing indicates the direction (angle) of rotation around the longitudinal direction of case body 100 as an axis.

[0109] <Toothbrush set> As shown in FIG. 8, the toothbrush set 1 according to the embodiment includes a storage case 10, a toothbrush 300, and a container (hereinafter simply referred to as "container") 400 that stores a mouthwash.

[0110] <Toothbrush> As shown in FIG. 12 , the main dimensions that define the size of toothbrush 300 are length L3, width W3, and the thickness of grip 310 (not shown). These dimensions can be defined arbitrarily. The dimensions of toothbrush 300 according to this embodiment are defined as follows: Length L3 is the dimension of the longest part in the longitudinal direction of toothbrush 300, and is the distance between the tip of head 320 and the tip of grip 310. Width W3 is the dimension of the widest part in the lateral direction of toothbrush 300, and is the maximum width of grip 310. The thickness of grip 310 is the maximum thickness of grip 310 of toothbrush 300.

[0111] If toothbrush 300 is for adults, length L3 is, for example, 180 mm. If toothbrush 300 is for adults, width W3 is, for example, 9 mm. If toothbrush 300 is for adults, grip 310 has a thickness of, for example, 10 mm. The cross-sectional shape of grip 310 and head 320 of toothbrush 300 along the thickness direction can be selected arbitrarily, and can be formed into, for example, a substantially circular, elliptical, or polygonal shape (rectangular, triangular, etc.).

[0112] For structures of toothbrush 300 that are not described, structures similar to those of known toothbrushes can be adopted.

[0113] <Container> As shown in FIG. 13, the main dimensions that define the size of the container 400 are the length L4, width W4, and outer diameter H4. These dimensions can be defined arbitrarily. The dimensions of the container 400 according to this embodiment are defined as follows: The length L4 is the dimension of the longest part of the container 400 in the longitudinal direction. The width W4 is the dimension of the widest part of the container 400 in the lateral direction, and is the width of the laminated portion 430. The outer diameter H4 is the outer diameter dimension of the cap portion 440 of the container 400.

[0114] The length L4 is, for example, 113 mm, the width W4 is, for example, 35 mm, and the outer diameter H4 is, for example, 22 mm.

[0115] For the structure of the container 400 not described, the same structure as that of a known container can be adopted.

[0116] <Containment Case> The storage case 10 includes a case body 100 and a cap 200 .

[0117] As shown in Fig. 8, the main dimensions that define the size of the storage case 10 are the longitudinal dimensions L1 and L2, the lateral dimension W1, and the depth dimension D1. These dimensions are set taking into consideration the ease of putting the toothbrush 300 and the container 400 into and out of the storage case 10, the portability of the toothbrush set 1, and other factors. Note that length L1 is the total length in the longitudinal direction when the cap 200 is attached to the case body 100. Furthermore, length L2 is the total length of the cap 200.

[0118] The length L1 is, for example, 190 mm. The length L2 is, for example, 55 mm. The width W1 is, for example, 45 mm. The depth D1 is, for example, 45 mm. The case body 100 has a case member 110 having a first space 113 and an opening 115, and a cover member 120.

[0119] 11, the case member 110 has a half-split cylindrical shape extending along the longitudinal direction. A lid member 120 is connected to one end of the case member 110 in the width direction (the end indicated by the arrow Y2) via a hinge portion 130, which will be described later.

[0120] First space 113 can accommodate grip 310 of toothbrush 300 and container 400. First space 113 is formed inside case member 110. The specific range of toothbrush 300 accommodated in first space 113 is not particularly limited.

[0121] The first space 113 may be provided with a holding portion 181 as a fixing portion 180 that can fix the position of the container 400 relative to the case member 110 when the container 400 is housed in the case main body 100. The first space 113 may also be provided with a partition rib portion 190 that separates an area that houses the grip 310 side of the toothbrush 300 (toothbrush housing portion 113B) from an area that houses the container 400 (toothpaste housing portion 113A). The structures of the holding portion 181 and the partition rib portion 190 will be described later.

[0122] Opening 115 allows toothbrush 300 and container 400 to be removed from first space 113. Opening 115 is formed over substantially the entire length of case member 110. As shown in FIG. 11 , opening 115 has a substantially rectangular planar shape.

[0123] The longitudinal dimension of opening 115 can be, for example, 85% or more and 96% or less of the total longitudinal length of case body 100 (the total longitudinal length of case body 100 including cap attachment portion 150, which will be described later). By setting the longitudinal dimension of opening 115 to such a length, toothbrush 300 can be easily inserted and removed from first space 113 through opening 115 even when cap 200 is attached to case body 100.

[0124] The case body 100 has an outer shape of a roughly triangular prism when the opening 115 is closed by the lid member 120. The bottom surface of the case body 100 (the end surface on the side indicated by the arrow X2 in the figure) has a roughly triangular planar shape. A user can place the storage case 10 upright by placing the bottom surface of the case body 100 on a desk or the like. This allows the case body 100 to be stored in a smaller space. Furthermore, because the case body 100 has a roughly triangular prism shape, even if the storage case 10 is placed sideways on a desk or the like, the storage case 10 can be prevented from rolling.

[0125] Lid member 120 is configured to be able to open and close opening 115. A concave space is formed inside lid member 120. When lid member 120 closes opening 115, a split surface formed along the periphery of case member 110 and a split surface formed on the periphery of lid member 120 are arranged to face each other. When lid member 120 closes opening 115, removal of toothbrush 300 and container 400 from opening 115 is restricted.

[0126] The lid member 120 can be provided with a fixing rib portion 182 as a fixing portion 180 that can fix the position of the container 400 relative to the case member 110 when the container 400 is housed in the case body 100 and the opening 115 is closed by the lid member 120. The structure of the fixing rib portion 182 will be described later.

[0127] The case body 100 also has a hinge portion 130 and a lock portion 140 .

[0128] Hinge unit 130 connects case member 110 and lid member 120, and allows lid member 120 to open and close opening 115 in response to a rotational operation. Lock unit 140 maintains a state in which opening 115 is closed by lid member 120. In this embodiment, lid member 120 opens and closes opening 115 in response to a rotational operation around an axis that is the longitudinal direction of case body 100.

[0129] A plurality of hinge portions 130 are provided and arranged side by side with a predetermined interval between them along the longitudinal direction of case member 110. Hinge portion 130 can be configured integrally with case member 110 and lid member 120, for example.

[0130] The locking portion 140 has a fitting hole 141 provided in the case member 110 and a protrusion 143 provided on the cover member 120 .

[0131] Furthermore, the case member 110 has a cap attachment portion 150 as shown in FIGS.

[0132] The cap attachment part 150 is provided at one longitudinal end part (the end part located in the direction indicated by the arrow X1) of the case member 110. The cap attachment part 150 protrudes in the longitudinal direction of the case member 110. The cap 200 can be fitted into the cap attachment part 150.

[0133] When attached to the case body 100, the cap 200 has a second space 203 that can accommodate a portion of the toothbrush 300 different from the portion accommodated in the first space 113. As shown in FIGS. 9 and 10 , a third space 153 is formed inside the cap attachment part 150 that can accommodate at least a portion of the head 320 side of the toothbrush 300 together with the second space 203 when the cap 200 is fitted into the cap attachment part 150. The third space 153 is disposed inside the second space 203 when the cap 200 is fitted into the cap attachment part 150. A notch can be provided in a portion of the circumferential direction of the cap attachment part 150 to promote elastic deformation of the cap attachment part 150 when the cap 200 is attached or detached. In addition, a rib can be provided on the outer peripheral surface of the cap attachment part 150 to increase the fixing force of the cap 200 to the cap attachment part 150.

[0134] Furthermore, the case member 110 and the cover member 120 have a partition wall 160 and a communication portion 170, as shown in FIG.

[0135] When the opening 115 is closed by the cover member 120 (see FIG. 8), the partition wall 160 can separate the first space 113 from the third space 153. In addition, as shown in FIG. 14, the partition wall 160 is formed with a communication portion 170 that communicates between the first space 113 and the third space 153.

[0136] As shown in FIGS. 10, 11, and 14, the partition wall 160 has a first wall portion 161 provided on the case member 110 and a second wall portion 162 provided on the cover member 120.

[0137] When the opening 115 is closed by the cover member 120, the first wall portion 161 and the second wall portion 162 abut against each other, thereby forming a single wall portion that separates the first space portion 113 and the third space portion 153.

[0138] As shown in FIG. 14, the partition wall 160 is formed with a communication section 170 that connects the first space section 113 and the third space section 153 to each other.

[0139] 10 and 14, the communication portion 170 has a first recess 171 formed in a part of the first wall portion 161 and a second recess 172 formed in a part of the second wall portion 162. The first recess 171 and the second recess 172 are arranged opposite each other when the cover member 120 closes the opening 115. When the first recess 171 and the second recess 172 are arranged opposite each other, they form a hole that communicates between the first space 113 and the third space 153.

[0140] When toothbrush 300 is stored in storage case 10 (see FIGS. 8 and 9), part 301 of toothbrush 300 (the grip 310 side of toothbrush 300) can be stored in first space 113. The head 320 side of toothbrush 300 can be placed in second space 203 and third space 153 through communication part 170.

[0141] In the storage case 10, the head 320 side of the toothbrush 300 is accommodated in the second space 203 of the cap 200. Therefore, the longitudinal dimension of the case member 110 can be made smaller than when the case member 110 is configured to accommodate the toothbrush 300 only in the first space 113 of the case member 110. Furthermore, when the cap 200 is attached to the cap attachment portion 150, the second space 203 and the third space 153 partially overlap in the longitudinal direction of the storage case 10. Therefore, the overall longitudinal length of the storage case 10 can be made smaller than when a structure is adopted in which the cap 200 is attached and detached at a position closer to one end of the storage case 10 in the longitudinal direction than the cap attachment portion 150.

[0142] Furthermore, the case member 110 has a visible portion M as shown in FIG.

[0143] The visible portion M is a through-hole (second opening) 115B that connects the first space 113 formed in the first surface 110A of the case member 110 to the outside of the case body 100. The visible portion M is provided at a predetermined distance in the longitudinal direction from the bottom surface (the end surface indicated by the arrow X2 in the figure) of the case member 110 (see FIG. 9). The predetermined distance is set depending on the length L4 of the container 400, and is set at a position where a character string P (at least one of a serial number and a serial code) written on the laminated portion 430 of the container 400 housed in the case member 110 can be seen from the visible portion M. For example, when purchasing the toothbrush set 1, a user can see the character string P written on the laminated portion 430 from outside the case body 100 through the visible portion M.

[0144] Furthermore, the case member 110 has a plurality of ventilation sections N as shown in FIG.

[0145] The ventilation section N is a through-hole (third opening) 115C that connects the first space 113 formed in the first surface 110A that forms the case member 110 with the outside of the case body 100. A plurality of ventilation sections N are provided above the visual confirmation section M (the side indicated by the arrow X1 in FIG. 9). The plurality of ventilation sections N ensures breathability within the first space 113. Therefore, when the user stores the used toothbrush 300 and container 400 in the case body 100 and closes the lid member 120 on the case member 110, the toothbrush 300 and container 400 can be dried through the plurality of ventilation sections N.

[0146] The number of ventilation sections N may be plural or may be one.

[0147] Next, the structures of the fixing portion 180 and the partition rib portion 190 will be described with reference to FIGS.

[0148] (fixed part) The fixing portion 180 can fix the position of the container 400 relative to the case member 110 when the container 400 is housed in the case main body 100. Therefore, when the lid member 120 is closed on the case member 110, the container 400 housed in the case member 110 can be prevented from moving within the case main body 100. For example, if a storage case without the fixing portion 180 is used, and the storage case is tilted during shipping or receives an impact, the container 400 may swing in its movement direction (for example, the longitudinal direction or rotational direction of the storage case). This can cause a problem in that the position of the container 400 within the storage case is unstable.

[0149] (holding part) As shown in FIG. 10 , the holding portion 181 has a hook portion 181B provided on the inner surface of the case member 110. A groove portion 181A that can fit with the cap portion 440 of the container 400 is formed in the hook portion 181B. A user can guide the cap portion 440 from the opening 115 toward the groove portion 181A. The hook portion 181B can partially clamp the cap portion 440 inserted into the groove portion 181A in the circumferential direction of the cap portion 440 (see the E-E cross section in FIG. 15 ). Therefore, the holding portion 181 can prevent the container 400 housed in the case member 110 from moving in the longitudinal direction of the case member 110. Therefore, the holding portion 181 can prevent the container 400 housed in the case member 110 from moving within the case main body 100.

[0150] As shown in Figure 11, the holding portion 181 in this embodiment extends in the short direction of the case member 110 from one end side of the short direction of the case member 110 (the side indicated by arrow Y1 in the figure) toward the partition rib portion 190, and is provided on a plane perpendicular to the longitudinal direction of the case member 110.

[0151] The groove 181A is U-shaped as shown in Fig. 16. The groove 181A has a substantially rectangular entrance side and a substantially semicircular back side.

[0152] The main dimensions that define the size of the holding portion 181 are the width W18 of the groove portion 181A and the depth D18 of the groove portion 181A. These dimensions can be defined arbitrarily. The dimensions of the groove portion 181A according to this embodiment are defined as follows. The width W18 is the opening dimension on the entrance side of the groove portion 181A, and is the dimension along the short direction of the case member 110. The depth D18 is the dimension perpendicular to the width W18, and is the dimension along the depth direction of the case member 110.

[0153] Width W18 of groove 181A is set to be slightly narrower than outer diameter H4 of cap portion 440, for example. In this case, the inner peripheral surface of holding portion 181 that forms groove 181A can provide sliding resistance to the outer peripheral surface of cap portion 440. A user can fit cap portion 440 of container 400 into holding portion 181 by guiding cap portion 440 into hook portion 181B while pushing and widening groove 181A with cap portion 440 of container 400.

[0154] The width W18 of groove 181A is not limited as long as it is a dimension that can fit cap portion 440 of container 400. Width W18 of groove 181A takes into consideration the ease of use when a user puts container 400 in and takes it out of storage case 10, and is preferably set within a range that allows hook portion 181B to apply sliding resistance to the outer peripheral surface of cap portion 440 of container 400 and does not impede the ease of use of the user.

[0155] Furthermore, the depth D18 of the groove portion 181A is a dimension that can fit the cap portion 440 of the container 400, and is not particularly limited as long as the container 400 fitted into the holding portion 181 does not hinder the user from opening and closing the lid member 120 relative to the case member 110.

[0156] Furthermore, the shape of groove 181A is not particularly limited as long as it can fit cap 440 of container 400. For example, groove 181A may have a shape that combines an oval shape and a polygonal shape (such as a rectangle or a triangle).

[0157] (Fixed rib part) 10, the fixed rib portion 182 stands upright from the inner surface of the lid member 120 and extends along the short side of the lid member 120. When viewed from the front of the lid member 120 (see FIG. 11), the fixed rib portion 182 is provided from one end side (the side indicated by arrow Y2 in the figure) to the other end side (the side indicated by arrow Y1 in the figure) in the short side of the lid member 120.

[0158] When the lid member 120 is closed on the case member 110, the end face 182a of the convex portion forming the fixing rib portion 182 partially abuts against the surface 400b of the container 400 housed in the case body 100, and the container 400 can be pressed against the inner surface of the case member 110 (see the CC cross section in FIG. 15). Therefore, the fixing rib portion 182 can prevent the container 400 from rotating inside the toothpaste housing portion 113A.

[0159] The fixing portion 180 has been described above, but the holding portion 181 and the fixing rib portion 182 can be modified in various ways as long as they achieve the effects of the present invention.

[0160] For example, there is no particular limitation on the contact relationship between the holding portion 181 and the cap portion 440. The hook portion 181B and the cap portion 440 may be in surface contact, line contact, or point contact.

[0161] Furthermore, there are no particular limitations on the thickness of the retaining portion 181 or the fixing rib portion 182. The thicknesses of the retaining portion 181 and the fixing rib portion 182 are dimensions defined along the longitudinal direction of the case body 100. There are no particular limitations on the thickness of the retaining portion 181 or the fixing rib portion 182, as long as they are dimensions that allow the cap portion 440 of the container 400 to be fitted thereto or that allow the container 400 to be held down, the strength required as a rib is ensured, and the thickness is such that it does not affect the external appearance of the case body 100 when the case body 100 is molded.

[0162] Furthermore, the holding portion 181 and the fixing rib portion 182 are preferably provided on a plane perpendicular to the longitudinal direction, but may be provided at an angle to the YZ plane.

[0163] (Partition rib section) 10 and 11, the partition rib 190 is provided standing from the inner surface of the case member 110 and extends from the bottom surface of the case member 110 (the end surface on the side indicated by the arrow X2 in the figures) along the longitudinal direction of the case member 110. The partition rib 190 can divide the first space 113 into a toothpaste storage section 113A that stores the container 400 and a toothbrush storage section 113B that stores the grip 310 side of the toothbrush 300.

[0164] The main dimensions that define the size of the toothbrush storage compartment 113A and the toothbrush storage compartment 113B are the width W20 of the toothbrush storage compartment 113B, which corresponds to the short side direction of the case member 110, and the width W21 of the toothbrush storage compartment 113B. These dimensions can be defined arbitrarily. The dimensions of the partition rib portion 190 according to this embodiment are defined as follows. The widths W20 and W21 are dimensions defined along the short side direction of the case member 110. The width W20 is the dimension provided on the top side of the toothbrush storage compartment 113B (the side indicated by the arrow X1 in the figure) when viewed from the front of the case member 110 (see FIG. 11). The width W21 is the dimension provided on the bottom side of the case member 110 (the side indicated by the arrow X2 in the figure).

[0165] The partition rib 190 is provided so as to incline from one end (the side indicated by the arrow X2 in the figure) to the other end (the side indicated by the arrow X1 in the figure) in the longitudinal direction of the case member 110 when viewed from the front of the case member 110 (see FIG. 11). Therefore, the width of the toothbrush storage section 113B increases from width W21 to width W20.

[0166] When a user places a portion of toothbrush 300 into case body 100 from the top side of case body 100 (the side indicated by arrow X1 in the figure) through communication portion 170, or when placing toothbrush 300 into case body 100 through opening 115, the user can restrict the position of toothbrush 300 within first space 113 by partition rib portion 190. The user can distinguish between the storage location of toothbrush 300 (the position within first space 113) and the storage location of container 400, and store toothbrush 300 and container 400 in case body 100 without them interfering with each other.

[0167] As described above, toothbrush storage section 113B has a tapered shape toward the bottom side of case member 110. Therefore, with this structure, case body 100 can ensure ease of insertion when a user inserts grip 310 side of toothbrush 300 into toothbrush storage section 113B from the top side of case body 100 via communication section 170.

[0168] Furthermore, the partitioning rib portion 190 can partially abut against the container 400 housed in the toothpaste housing portion 113A by taking advantage of the fact that the width W20 of the toothbrush housing portion 113B is set wider than the width W21. Therefore, the partitioning rib portion 190 can prevent the container 400 from rotating inside the toothpaste housing portion 113A.

[0169] The dimensions of width W20 and width W21 of toothbrush housing section 113B are not particularly limited. However, width W21 is preferably set larger than width W3 of toothbrush 300 and the thickness of grip 310, taking into consideration the ease of use when a user places toothbrush 300 in and removes it from storage case 10. Width W20 of toothbrush housing section 113B takes into consideration the ease of use when a user places container 400 in and removes it from storage case 10, and is preferably set within a range that allows partition rib section 190 to provide sliding resistance against the outer peripheral surface of container 400 without impeding the user's ease of use.

[0170] Furthermore, the depth dimension (maximum depth dimension of the toothpaste storage section 113A) D22 of the toothpaste storage section 113A along the insertion direction (depth direction of the case member 110) in which the container 400 is inserted into the first space section 113 through the opening 115 is larger than the width dimension (maximum width dimension of the toothpaste storage section 113A) W22 of the toothpaste storage section 113A along the short direction of the case member 110, and the width dimension W22 of the toothpaste storage section 113A is set to gradually decrease toward the inner surface in the depth direction of the toothpaste storage section 113A (see Figure 16).

[0171] In this embodiment, the width W4 of the container 400, which is the maximum width, is larger than the width W22 and depth D22 of the toothpaste container 113A, but smaller than the diagonal dimension T22 formed by the width W22 and depth D22 of the toothpaste container 113A. The width W22 of the toothpaste container 113A gradually decreases toward the inner surface in the depth direction of the toothpaste container 113A. Therefore, when the container 400 is inserted (stored) in the toothpaste container 113A, one end 400a (see cross-sectional views CC and DD in FIG. 15 ) of the container 400 in the lateral direction faces the end 113C where the case member 110 and the partition rib portion 190 intersect. Therefore, the laminated portion 430 of the container 400 is stored in the toothpaste storage portion 113A in a state inclined at a predetermined angle θ1 (see Figures 15 and 16) with respect to the XZ plane, in the direction θ of rotation around the longitudinal direction of the case main body 100 as the axis.

[0172] Although the angle θ1 is not particularly limited, it is preferably about 30 degrees when the shape of the case body 100 is a substantially equilateral triangular prism. When the container 400 according to this embodiment is housed in the toothpaste housing portion 113A, the laminated portion 430 of the container 400 is arranged along the first surface 110A that forms the case member 110. Therefore, the angle θ1 can be changed in various ways to suit the shape of the case body 100.

[0173] Next, the structure of each component that makes up the cap 200 will be described with reference to FIGS.

[0174] Cap 200 is detachably attached to case body 100 at one longitudinal end of case body 100 (the end indicated by arrow X1 in the figure). When cap 200 is attached to case body 100, cap 200 has second space 203 that can accommodate head 320 of toothbrush 300 (a portion different from the portion accommodated in first space 113). However, the specific range of toothbrush 300 that can be accommodated in second space 203 is not particularly limited.

[0175] <How to use> As shown in FIGS. 8 and 9, in the storage case 10, the opening 115 can be opened and closed by the lid member 120 when the cap 200 is attached to the case body 100.

[0176] As shown in FIG. 10, the cap 200 can be attached to and detached from the case body 100 by moving the cap 200 relatively toward and away from one end of the case body 100 in the longitudinal direction of the case body 100 along the longitudinal direction of the case body 100.

[0177] Cap 200 can be attached to case body 100 by sliding it in a direction toward case body 100 (movement in the direction indicated by arrow A1 in FIG. 10). Cap 200 can also be removed from case body 100 by sliding it in a direction away from case body 100 (movement in the direction indicated by arrow A2 in FIG. 10) while attached to case body 100.

[0178] When cap 200 is removed from case body 100, it can hold a liquid in second space 203. For example, a user can hold water in second space 203. The user can use the water held in second space 203 to rinse the inside of the mouth after brushing their teeth with toothbrush 300.

[0179] The case body 100 has been described above. The case body 100 (case member 110 and lid member 120) can be made of, for example, a resin material. Furthermore, when the case body 100 is made of a resin material, the resin material can be colored to provide opacity. Furthermore, when the case body 100 is made of a resin material, an antibacterial agent can be incorporated into the resin material. Examples of resin materials include polypropylene and polyethylene. Examples of antibacterial agents include silver-based soluble glass antibacterial agents, silver-based glass antibacterial agents, zinc-based soluble glass antibacterial agents, and silver-based zirconium phosphate antibacterial agents. When the case body 100 is opaque, the visibility of the toothbrush 300 and the container 400 stored in the storage case 10 is reduced. Therefore, the design and appearance of the storage case 10 can be prevented from being damaged when the storage case 10 is carried around. Furthermore, when the case member 110 and the lid member 120 are made of an antibacterial material, the user can use the toothbrush set 1 hygienically for a long period of time. The case member 110 and the cover member 120 may be made of different materials, and may be colored differently.

[0180] The cap 200 can be formed, for example, from the same material as the case body 100. The cap 200 can be configured to be opaque. Furthermore, an antibacterial agent can be kneaded into the resin material that forms the cap 200.

[0181] Next, the effects of this embodiment will be described.

[0182] The storage case 10 according to this embodiment includes a case body 100 including a case member 110 having a first space 113 capable of housing a container 400 and a portion of the toothbrush 300 and an opening 115 that allows the container 400 and the toothbrush 300 to be removed from the first space 113, and a lid member 120 that opens and closes the opening 115. The case body 100 includes a fixing portion 180 that fixes the container 400. The fixing portion 180 includes at least one of a holding portion 181 that is provided on the inner surface of the case member 110 and that holds at least a portion of the container 400 to prevent the container 400 from moving in the longitudinal direction of the case member 110, and a fixing rib portion 182 that is provided on the inner surface of the lid member 120 and that abuts against the container 400 when the opening 115 is closed by the lid member 120 to prevent the container 400 from rotating within the first space 113.

[0183] According to the storage case 10 configured as described above, when the container 400 is stored in the case main body 100, the position of the container 400 can be fixed relative to the case member 110. Therefore, when the lid member 120 is closed on the case member 110, the container 400 stored in the case member 110 can be prevented from moving within the case main body 100.

[0184] Furthermore, the holding portion 181 has a hook portion 181B that extends in the short direction of the case member 110 and has a groove portion 181A formed therein that can fit into at least a part of the cap portion 440 of the container 400. The fixing rib portion 182 has a protrusion that presses the container 400 against the inner surface of the case member 110 when the opening 115 is closed by the lid member 120. This allows the fixing rib portion 182 to prevent the container 400 from rotating within the toothpaste storage portion 113A.

[0185] Furthermore, the case member 110 has a partition rib portion 190 extending along the longitudinal direction of the case member 110 to separate the first space 113 into a toothpaste storage portion 113A that stores the container 400 and a toothbrush storage portion 113B that stores a portion of the toothbrush 300. This allows the user to distinguish between the storage location for the toothbrush 300 and the storage location for the container 400. Furthermore, the case main body 100 ensures ease of insertion when the user inserts the grip 310 side of the toothbrush 300 into the toothbrush storage portion 113B from the top side of the case main body 100 via the communication portion 170. Furthermore, the partition rib portion 190 partially abuts against the container 400, thereby preventing the container 400 from rotating within the toothpaste storage portion 113A.

[0186] The partition rib 190 extends from the inner surface of the case member 110. The depth D22 (maximum depth of the toothpaste storage section 113A) of the toothpaste storage section 113A along the insertion direction (depth direction of the case member 110) of the container 400 inserted through the opening 115 into the first space 113 is greater than the width W22 (maximum width of the toothpaste storage section 113A) of the toothpaste storage section 113A along the short side of the case member 110. The width W22 of the toothpaste storage section 113A gradually decreases toward the inner surface in the depth direction of the toothpaste storage section 113A. This allows the laminated section 430 of the container 400 to be stored in the toothpaste storage section 113A tilted at a predetermined angle θ1 with respect to the XZ plane in the direction θ of rotation about the longitudinal direction of the case body 100.

[0187] Furthermore, case body 100 further has a visible portion M that allows a character string P (at least one of a serial number and a serial code) written on container 400 housed in first space 113 to be visible from outside case body 100 when opening 115 is closed by lid member 120. This allows a user to see character string P written on laminated portion 430 from outside case body 100 via visible portion M, for example, when purchasing toothbrush set 1.

[0188] Furthermore, the visible portion M is provided in the case member 110 and has a second opening 115B that connects the first space 113 with the outside of the case body 100. This allows the user, for example, when purchasing the toothbrush set 1, to view the character string P printed on the laminated portion 430 from outside the case body 100 through the second opening 115B.

[0189] Furthermore, case body 100 is made of an opaque material, which prevents toothbrush 300 and container 400 housed in case body 100 from being seen from the outside of case body 100, thereby maintaining the appearance and design of case body 100.

[0190] Case body 100 also has third opening 115C that ensures breathability by connecting first space 113 with the outside of case body 100. This allows the user to dry toothbrush 300 and container 400 through third opening 115C when storing used toothbrush 300 and container 400 in case body 100 and closing lid member 120 on case member 110.

[0191] The storage case 10 further includes a cap 200 that is detachably attached to the case body 100 at one end side in the longitudinal direction of the case body 100, and that, when attached to the case body 100, has a second space 203 that can accommodate a portion of the toothbrush 300 different from the portion accommodated in the first space 113. The lid member 120 can open and close the opening 115 when the cap 200 is attached to the case body 100. Therefore, the user does not need to remove the cap 200 from the case body 100 when taking the toothbrush 300 and the container 400 in and out of the case body 100. Therefore, the storage case 10 can suppress a decrease in convenience that may occur when removing the cap 200 from the case body 100 when taking the toothbrush 300 and the container 400 in and out of the case body 100.

[0192] Furthermore, when the cap 200 is removed from the case body 100, the cap 200 can hold liquid in the second space 203. This allows the user to use the cap 200 as a cup when brushing their teeth. This further improves the convenience of the storage case 10.

[0193] The toothbrush set 1 also includes a storage case 10, a toothbrush 300 that can be stored in the storage case 10, and a container 400 that can be stored in the storage case 10. With this configuration, it is possible to provide a toothbrush set 1 that can prevent the container 400 stored in the case member 110 from moving within the case body 100 when the cover member 120 is closed on the case member 110.

[0194] <Example> The present invention will be described below based on examples, but the present invention is not limited to the following examples. In the description of the examples, the names of the components described in the above-mentioned embodiment will be used.

[0195] The following examples and comparative examples were subjected to evaluation tests for evaluation item 1 below.

[0196] (Evaluation item 1) Difficulty in rotating containers stored in a storage case As Examples 1, 2, and 3, storage cases having the following configurations 1 and 2 shown in Table 4 were prepared. Configuration 1: Holding part Configuration 2: Fixed rib section As Comparative Example 1, a storage case not having the following features 1 and 2 was prepared. Configuration 1: Holding part Configuration 2: Fixed rib section In the evaluation test, a panel of 10 experts conducted 10 evaluation tests using the storage cases of Examples 1, 2, and 3 and Comparative Example 1. The evaluation score is the average score of the 10 evaluation tests. (Evaluation criteria) 7 points: Very good. 6 points: Quite good. 5 points: Fairly good. 4 points: Can't say either way. 3 points: Not very good. 2 points: Not very good. 1 point: Very poor.

[0197] [Table 4]

[0198] The evaluation results of this example will be described.

[0199] Comparing Example 1 with Comparative Example 1, it is clear that the fixing rib portion can increase the force of suppressing rotation of the container housed in the housing case.

[0200] Comparing Example 2 with Comparative Example 1, it is clear that the holding portion can increase the force of suppressing rotation of the container housed in the storage case.

[0201] Comparing Example 1 and Example 2, it is clear that the holding portion can suppress the rotation of the container housed in the housing case more effectively than the fixing rib portion.

[0202] This example demonstrates that the container case can suppress rotation of the container housed in the container case by providing either the holding portion or the fixing rib portion.

[0203] Furthermore, when Example 3 is compared with Example 1 or Example 2, it is demonstrated that when both a holding portion and a fixed rib portion are provided, the force of suppressing rotation of the container contained in the storage case can be further increased compared to when only one of a holding portion and a fixed rib portion is provided.

[0204] This embodiment can be modified in various ways within the scope of the claims. For example, the visual confirmation portion does not have to be formed by a through-hole (opening). While the storage case is formed from an opaque material, the visual confirmation portion may be formed from a transparent material. The configuration of the visual confirmation portion is not limited to a through-hole, and can be modified in various ways as long as the effects of the invention can be achieved.

[0205] Next, a toothbrush set 1 and a storage case 10 according to a second modified example will be described with reference to FIGS.

[0206] Arrows X1-X2 shown in each drawing indicate the longitudinal direction of case body 100, arrows Y1-Y2 indicate the width direction (short direction) of case body 100, and arrows Z1-Z2 indicate the depth direction of case body 100. The longitudinal direction of storage case 10, the longitudinal direction of case member 110, and the longitudinal direction of cover member 120 are substantially the same direction as the longitudinal direction of case body 100.

[0207] As shown in FIG. 17, the toothbrush set 1 of this modification includes a storage case 10, a toothbrush 300, and a container (hereinafter simply referred to as "container") 400 that stores a mouthwash.

[0208] The storage case 10 includes a case body 100 and a cap 200 .

[0209] Case body 100 has therein a first space 113 capable of accommodating a portion 301 of toothbrush 300 and container 400. Cap 200 is detachably attached to case body 100 at one end side of case body 100 in the longitudinal direction. When cap 200 is attached to case body 100, it has therein a second space 203 capable of accommodating a portion 302 of toothbrush 300 different from portion 301 accommodated in first space 113.

[0210] 18, the case body 100 includes a case member 110 and a cover member 120. The case body 100 also includes hinge portions 131 and 132 and a lock portion 140.

[0211] In addition, the case body 100 may have a structure such as a fixed rib inside to prevent the container 400 from moving longitudinally or rotating around the longitudinal direction within the first space portion 113, and an opening communicating with the interior may be formed in the outer wall to allow ventilation and to allow the container 400 to be viewed, but there is no particular limitation on the type of structure to be provided inside or on the outer surface of the case body 100.

[0212] One longitudinal end of case body 100 (the end located in the direction indicated by arrow X1) is provided with cap attachment section 150 that protrudes in the longitudinal direction of case body 100 and into which cap 200 can be fitted. A third space 153 is formed inside cap attachment section 150. When cap 200 is fitted into cap attachment section 150, third space 153 can accommodate, together with second space 203, a part of portion 302 of toothbrush 300 that is different from portion 301 accommodated in first space 113. When cap 200 is fitted into cap attachment section 150, third space 153 is positioned inside second space 203.

[0213] The case body 100 (case member 110 and lid member 120) can be made of, for example, a resin material. When the case body 100 is made of a resin material, the resin material can be colored to provide opacity. When the case body 100 is made of a resin material, an antibacterial agent can be incorporated into the resin material. Examples of resin materials include polypropylene and polyethylene. Examples of antibacterial agents include silver-based soluble glass antibacterial agents, silver-based glass antibacterial agents, zinc-based soluble glass antibacterial agents, and silver-based zirconium phosphate antibacterial agents. When the case body 100 is opaque, the visibility of the toothbrush 300 and the container 400 stored in the storage case 10 is reduced. Therefore, the design and appearance of the storage case 10 can be prevented from being damaged when the storage case 10 is carried around. Furthermore, by forming the case member 110 and the lid member 120 from an antibacterial material, the user can use the toothbrush set 1 hygienically for a long period of time. The case member 110 and the cover member 120 may be made of different materials, and may be colored differently.

[0214] The case member 110 is provided with an opening 115 that allows the toothbrush 300 and the container 400 to be removed from the first space 113 .

[0215] The case body 100 has an outer shape of a roughly triangular prism when the opening 115 is closed by the lid member 120. The bottom surface of the case body 100 has a roughly triangular planar shape. A user can place the storage case 10 upright by placing the bottom surface of the case body 100 on a desk or the like. This allows the case body 100 to be stored in a smaller space. Furthermore, because the case body 100 has a roughly triangular prism shape, even if the storage case 10 is placed sideways on a desk or the like, the storage case 10 can be prevented from rolling.

[0216] Lid member 120 is rotatably connected to case member 110 via hinge portions 131 and 132, and opens and closes opening 115. Lid member 120 can open and close opening 115 when cap 200 is attached to cap attachment portion 150.

[0217] Hinge sections 131, 132 are arranged side by side at a predetermined interval along the longitudinal direction of case member 110. Each hinge section 131, 132 can be configured integrally with case member 110 and lid member 120, for example. Alternatively, each hinge section 131, 132 may be assembled to case body 100 by separately attaching a hinge structure having a rotatable shaft and a bearing to case member 110 and lid member 120, for example.

[0218] Locking portion 140 has a fitting hole 141 provided in case member 110 and a protrusion 143 provided on lid member 120. Protrusion 143 can be fitted into and disengaged from fitting hole 141. When lid member 120 is closed, locking portion 140 prevents lid member 120 from opening accidentally by fitting protrusion 143 into fitting hole 141. A user can open lid member 120 by disengaging protrusion 143 from fitting hole 141.

[0219] In addition to the locking portion 140, the case body 100 may be provided with a structure to prevent the lid member 120 from opening inadvertently. For example, the corners of the case member 110 and the lid member 120 may be provided with a structure that fits into each other when the lid member 120 is closed.

[0220] As shown in FIG. 19, the cap 200 can be attached to and detached from the case body 100 by moving the cap 200 relatively toward and away from one end of the case body 100 along the longitudinal direction of the case body 100.

[0221] The cap 200 is attached to the case body 100 by fitting into the cap attachment part 150. The cap 200 attached to the cap attachment part 150 can be detached from the cap attachment part 150 by being pulled along the longitudinal direction of the case body 100, and separated from the case body 100. When the cap 200 is detached from the cap attachment part 150, it can hold liquid inside and can be used as a cup.

[0222] The cap 200 can be formed, for example, from the same material as the case body 100. The cap 200 can be configured to be opaque. Furthermore, an antibacterial agent can be kneaded into the resin material that forms the cap 200.

[0223] In the cap attachment portion 150, an inner third space portion 153 communicates with the first space portion 113, and an open portion 152 is formed where the side wall 151 around the third space portion 153 is discontinued. The open portion 152 and the opening portion 115 are formed on the same side (Z1 direction side) that intersects with the longitudinal direction of the case body 100.

[0224] In the cap mounting portion 150, horizontal ribs 154, vertical ribs 155, and bosses 156 are provided on the outer surface of the side wall 151 as convex portions that abut the inside of the cap 200 when the cap 200 is fitted to the cap mounting portion 150.

[0225] The horizontal rib 154 extends in the circumferential direction of the side wall 151. The vertical rib 155 extends in the longitudinal direction of the case body 100. The boss 156 protrudes from one end of the vertical rib 155 on the other end side in the longitudinal direction of the case body 100 (the end located in the direction indicated by the arrow X2).

[0226] 20, the transverse ribs 154 are provided at three locations spaced at approximately equal intervals in the circumferential direction of the cap attachment portion 150, but the number of locations is not particularly limited, and the intervals between the transverse ribs 154 do not have to be equal but may vary. The width of the transverse ribs 154 in the circumferential direction is also not particularly limited. A configuration in which the transverse ribs 154 extend over the entire circumferential direction is also included within the scope of the present invention.

[0227] The vertical rib 155 is provided in a location in the cap mounting portion 150 close to the open portion 152, but where in the cap mounting portion 150 it is provided is not limited to this modified example, and there is also no limit to how many locations it is provided in.

[0228] 21, the vertical rib 155 has an end 157 that is inclined so as to narrow toward the cap 200. The shape of the end 157 is not limited to this, but if the end 157 has a shape that is inclined so as to narrow toward the cap 200, the cap 200 is less likely to get caught on the end 157 when the cap 200 is attached to the cap attachment part 150, and the cap 200 can be attached smoothly.

[0229] A recess 204 that fits onto the boss 156 is formed on the inside of the cap 200. The recess 204 is formed along the entire circumference of the inside of the cap 200, but it is sufficient that the recess 204 is formed in a position that allows it to fit onto the boss 156, and a configuration in which the recess 204 is formed on a portion of the circumference of the inside of the cap 200 is also included in the scope of the present invention.

[0230] Furthermore, recess 204 is formed close to the opening of cap 200, but there are no particular limitations on where in the depth direction of cap 200 recess 204 is formed, as long as it is located in a position that allows engagement with boss 156. If recess 204 is formed close to the opening of cap 200, as in this modified example, cap 200 can be easily removed from the mold when it is molded.

[0231] Next, the effects of this modification will be described.

[0232] As shown in Figure 22, in this modified example, an opening 152 is formed in the cap attachment portion 150 of the case body 100 by interrupting the side wall 151, and the toothbrush 300 is less likely to interfere with the cap attachment portion 150 when being inserted or removed, making it easier to insert or remove the toothbrush 300.

[0233] For example, when using a toothbrush container equipped with a conventional case body, the user first removes the cap that fits onto one end of the case body and then inserts or removes the toothbrush through that end, but because the entire toothbrush fits inside the case body, the user must insert or remove the toothbrush by sticking their finger into the case body from that end, making it difficult to do so. To address this issue, if the side wall at one end of the case body were partially cut out to make it easier to insert or remove the toothbrush, the case body and the cap would no longer fit together all around, which would reduce the strength of the fit of the cap and make it more likely to come off accidentally.

[0234] The cap attachment portion 150 of the case body 100 in this modified example has an open portion 152 formed therein, and therefore does not fit with the cap 200 all around. However, horizontal ribs 154, vertical ribs 155, and bosses 156 are provided as convex portions that abut the inside of the cap 200, and these and the inside of the cap 200 press against each other to interfere with each other, thereby increasing the fitting strength, and therefore the cap 200 attached to the cap attachment portion 150 is unlikely to come off accidentally.

[0235] The horizontal rib 154 extends in the circumferential direction of the side wall 151, and at a specific position in the longitudinal direction (X1-X2 direction) (the lower end of the cap attachment portion 150 in this modified example), it comes into contact with the inside of the cap 200 across a width in the circumferential direction, providing a wide interference range. For this reason, if the horizontal rib 154 is provided as a protrusion that abuts against the inside of the cap 200, it is possible to effectively improve the fitting strength at the specific position in the longitudinal direction (X1-X2 direction) (the lower end of the cap attachment portion 150 in this modified example).

[0236] The vertical ribs 155 extend in the longitudinal direction (X1-X2 direction) and come into contact with and interfere with the inside of the cap 200 over a wide area in the longitudinal direction (X1-X2 direction). Therefore, if the vertical ribs 155 are provided as protrusions that come into contact with the inside of the cap 200, the fitting strength can be increased over a wide area in the longitudinal direction (X1-X2 direction).

[0237] Furthermore, a boss 156 is provided at the lower end of the vertical rib 155, which fits into a recess 204 inside the cap 200 to prevent the cap 200 from coming off, thereby allowing the cap 200 to be fixed more reliably.

[0238] In the storage case 10 of this modified example, as shown in FIG. 18 , the opening 115 for inserting and removing the toothbrush 300 and the container 400 can be opened and closed with the cap 200 attached to the case body 100. Therefore, when inserting and removing the toothbrush 300 and the container 400 from the case body 100, the user does not necessarily have to remove the cap 200 from the case body 100. It is possible to use the toothbrush 300 and the container 400 after removing the cap 200, but in that case, it becomes necessary to place the removed cap 200 on a nearby desk or sink, or to store the cap 200 so that it does not get lost. On the other hand, in this modified example, it is not necessarily necessary to remove the cap 200, which is highly convenient.

[0239] Cap 200 can hold liquid inside when detached from cap attachment portion 150. With this configuration, a user can use cap 200 as a cup when brushing their teeth, improving the convenience of storage case 10.

[0240] As shown in Figure 23, the open portion 152 and the opening 115 are formed on the same side (Z1 direction side) that intersects with the longitudinal direction (X1-X2 direction), and when the cover member 120 is opened, space is created on the same side across the entire case member 110, making it easier to take the toothbrush 300 in and out.

[0241] This modified example can be modified in various ways within the scope of the claims. For example, in the modified case body 100 described above, the lid member 120 rotates relative to the case member 110 via hinge portions 131 and 132 to open and close, but the opening and closing mechanism is not limited to this and may be of other types. For example, a type in which the case member and the lid member slide relative to each other to open and close is also within the scope of the present invention. Furthermore, the case body of the present invention does not necessarily have to open and close; for example, a type in which the case body is a simple cylindrical body that does not open and close is also within the scope of the present invention.

[0242] Furthermore, in the above-described modified example, horizontal ribs 154, vertical ribs 155, and bosses 156 are disclosed as convex portions that come into contact with the inside of cap 200, but the present invention is not limited to a configuration in which all of these are provided. For example, the scope of the present invention also includes a configuration in which horizontal ribs and vertical ribs are provided as convex portions but no boss, a configuration in which only horizontal ribs are provided as convex portions, a configuration in which only vertical ribs are provided as convex portions, and a configuration in which vertical ribs and bosses are provided as convex portions but no horizontal ribs.
