[0005] Patent Document 1: Japanese Utility Model Application Publication No. 6-61769 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In the toothbrush set storage case disclosed in Patent Document 1, the toothbrush can be allowed to dry naturally even if it is stored without being fully dried after use. Conversely, if the storage case, stored in a damp state, is placed in a bag or similar item for carrying, there is a risk of the bag or similar item becoming contaminated by moisture leaking from the vents of the storage case.

[0008] Technical solutions for solving the problem

[0009] This invention provides a carrying case for oral hygiene products, comprising: a case body, which is composed of a bottomed cylindrical body and has a storage space for oral hygiene products; and a lid, which detachably covers the upper opening of the case body. The peripheral walls of the case body and the lid have corresponding point-symmetric cross-sectional shapes. A guide piece extending toward the other side of the case body and the lid is provided on a portion of the peripheral wall of one of the case body and the lid. A sliding surface that slides along the outer surface of the guide piece is provided on the other of the case body and the lid. One of the outer surface of the guide plate and the sliding surface is provided with a first locking part at a first connection position that locks the box body and the cover together, and a second locking part at a second connection position that separates the box body and the cover by a certain distance. The other of the outer surface of the guide plate and the sliding surface is provided with a locking part that selectively locks the first locking part or the second locking part. By displacing the relative angular positions of the box body and the cover, the state of the first locking part facing the locking part and the state of the second locking part facing the locking part are switched.

[0010] According to this structure, when a moist oral hygiene item is placed into the oral hygiene item carrying case, the second locking part engages with the locking part to lock at a second connecting position that separates the case body and the lid by a certain distance (a predetermined distance). This ensures sufficient air permeability of the oral hygiene item carrying case and effectively dries the oral hygiene items, such as toothbrushes, stored inside the case. On the other hand, when the oral hygiene item carrying case containing the oral hygiene items is placed in a bag or similar item for carrying, the first locking part engages with the locking part to lock at a first connecting position that seals the case body and the lid. This prevents moisture, dust, or debris leaking from inside the oral hygiene item carrying case from contaminating the bag or similar items and entering the case.

[0011] Alternatively, one of the box body and the lid may have an opening that allows the interior of the oral hygiene tool carrying case to be identified when the box body and the lid are in a closed state.

[0012] According to this structure, the contents of the oral hygiene tool carrying case can be viewed through the opening without detaching the lid from the main body of the case.

[0013] Alternatively, the opening is preferably formed by a cut extending along the gap formed between adjacent guide pieces.

[0014] According to this structure, demolding when forming the box body or lid through injection molding or other methods can be made easier, thus reducing the manufacturing cost of oral hygiene product carrying boxes.

[0015] In addition, the guide plate preferably has a flat portion extending along the peripheral wall of one of the box body and the cover body, and a folded portion provided on the side of the flat portion.

[0016] According to this structure, the following advantages are available: by setting the bent portion to reinforce the guide plate, its strength and rigidity can be fully ensured without increasing the thickness of the guide plate.

[0017] In addition, the guide plate is preferably configured to extend upward from the upper opening of the box body, and the sliding surface is formed by the inner surface of the peripheral wall of the cover.

[0018] According to this structure, it can be conveniently used as a rinsing cup when the lid is detached from the main body of the box.

[0019] In addition, preferably, the peripheral walls of the box body and the lid are approximately square in cross-sectional shape, and the box body is provided with: a guide plate having a flat portion extending upward from one side wall that constitutes its peripheral wall and a pair of left and right folded portions provided continuously on its left and right sides; and a guide plate having a flat portion extending upward from the other side wall opposite to the one side wall and a pair of left and right folded portions provided continuously on its left and right sides.

[0020] According to this structure, when connecting the lid to the box body, the lid can be supported by a pair of opposing guide plates located at the upper end of the box body, while the sliding surface of the lid can slide smoothly along the outer surface of the guide plates. Moreover, by increasing the opening area of ​​the gap formed between the two guide plates, the air permeability of the oral hygiene device carrying box can be sufficiently ensured when the second locking part of the lid is engaged with the locking part of the box body.

[0021] Invention Effects

[0022] The oral hygiene tool carrying case according to the present invention achieves the effect of ensuring sufficient air permeability of the oral hygiene tool carrying case as needed, and maintaining the airtightness of the oral hygiene tool carrying case. Attached Figure Description

[0034] Hereinafter, embodiments of the oral hygiene tool carrying case of the present invention will be described with reference to the accompanying drawings. Furthermore, structures marked with the same symbols in the figures represent the same structures, and their descriptions are omitted.

[0035] Figures 1-3 This invention illustrates an oral hygiene tool carrying case 1 according to an embodiment of the present invention. The oral hygiene tool carrying case 1 comprises: a case body 2, which is a bottomed cylindrical body with a storage space for accommodating oral hygiene tools 10, such as a toothbrush, and a toothpaste tube 11; and a lid 3, which detachably covers the upper opening of the case body 2. The materials of the case body 2 and the lid 3 are not particularly limited, but synthetic resins with a certain strength and rigidity, such as polypropylene and polyethylene, are preferred. Furthermore, the peripheral walls of the case body 2 and the lid 3 have corresponding point-symmetric cross-sectional shapes; in this embodiment, they are approximately square cross-sectional shapes with one side of equal length.

[0036] like Figure 4 and Figure 5 As shown, on the box body 2, a pair of guide plates 4, 4 are provided on a portion of the peripheral wall of the box body 2, extending upwards from its upper opening towards the lid 3. Specifically, one guide plate 4 is formed with a cross-section roughly shaped like the Japanese character "コ" (ko), having a flat portion 41 extending upwards from one side wall portion 21 constituting the peripheral wall of the box body 2, and a pair of bent portions 42 continuously provided on its left and right sides. The other guide plate 4 is also formed with a cross-section roughly shaped like the Japanese character "コ" (ko), having a flat portion 41 extending upwards from the other side wall portion 22 opposite to the aforementioned one side wall portion 21, and a pair of bent portions 42 continuously provided on its left and right sides. Furthermore, a gap 43 of a certain width is formed between the opposing bent portions 42 in the upper portion of the box body 2 where the two guide plates 4, 4 are not provided.

[0037] Engaging portions 44 are formed on the outer surfaces of the two guide pieces 4, 4, respectively, which selectively engage the first locking portion 31 or the second locking portion 32 described later. In this embodiment, the engaging portion 44, which is formed by a recess of a certain width and extends along the width direction of the flat portion 41, is formed near the upper end of the guide piece 4. In addition, a cut extending downward along the gap portion 43 is formed on the upper part of one of the side wall portions 23 and 24 of the box body 2 located between the side wall portions 21 and 22, i.e., the side wall portion 23 in the illustration. Through this cut, an opening 25 is formed that allows the interior of the oral hygiene tool carrying case 1 to be seen when the cover 3 and the box body 2 are in a closed state (see reference). Figure 2 ).

[0038] like Figure 4 As shown, a sliding surface 30, formed by the inner surface of its peripheral wall, is provided on the cover 3. By sliding this sliding surface 30 downward along the outer surface of the guide plate 4, the box body 2 and the cover 3 are connected as described later. Alternatively, by sliding the sliding surface 30 of the cover 3 in the connected state upward along the outer surface of the guide plate 4, the cover 3 is disengaged from the box body 2 (see reference). Figure 1 ).

[0039] On the sliding surface 30 of the cover 3, there are sealing positions at different angles that lock the cover 3 and the box body 2 together. Specifically, these are first connection positions that seal the lower end of the cover 3 with the upper opening of the box body 2 located at the base end of the guide plate 4 (see reference). Figure 2 The first locking part 31 of the cover 3 is locked at the second connecting position that separates the lower end of the cover 3 from the upper opening of the box body 2 by a certain distance (refer to the second connecting position). Figure 3 The second locking part 32.

[0040] That is, such as Figure 4 As shown, on the inner surface of one side wall portion 33 and the inner surface of the opposite side wall portion 34 constituting the peripheral wall portion of the cover body 3, at a certain distance L from the lower end of the cover body 3, a first locking portion 31 composed of protrusions is formed to engage with the engaging portion 44. On the inner surfaces of the opposite side wall portions 35 and 36, which are located at positions orthogonal to the aforementioned side wall portions 33 and 34, a second locking portion 32 composed of protrusions is formed near the lower end of the cover body 3 to engage with the aforementioned engaging portion 44. In addition, a step portion 37 is formed on the inner surfaces of the aforementioned side wall portions 35 and 36. This step portion 37 is used to restrict the cover body 3 from sliding downwards beyond the second connection position by abutting against the upper end of the guide piece 4 when the second locking portion 32 is engaged with the engaging portion 44.

[0041] Moreover, such as Figure 1 and Figure 4As shown, with the sidewalls 33 and 34 of the cover 3, which has the first locking part 31, facing the sidewalls 21 and 22 of the box body 2, which has the engaging part 44, the sliding surface 30 of the cover 3 slides downward along the outer surface of the guide piece 4, thereby engaging the first locking part 31 of the cover 3 with the engaging part 44 of the box body 2. As a result, as... Figure 2 As shown, it is locked at the first connection position where the box body 2 and the cover 3 are tightly joined.

[0042] like Figure 6 As shown, by rotating the box body 2 and the lid 3 90 degrees relative to each other from the aforementioned opposing state, the side wall portions 35 and 36 of the lid 3, which are provided with the second locking portion 32, are positioned facing the side wall portions 21 and 22 of the box body 2. In this state, the sliding surface 30 of the lid 3 slides downward along the outer surface of the guide plate 4. As a result, the stepped portion 37 of the lid 3 abuts against the upper end of the guide plate 4, restricting the lid 3 from sliding further downward, and the second locking portion 32 of the lid 3 engages with the engaged portion 44 of the box body 2. As a result, as... Figure 3 As shown, it is stopped at the second connection position where the box body 2 and the cover 3 are separated by a certain distance.

[0043] Furthermore, when storing the toothpaste tube 11 into the oral hygiene tool carrying case 1, such as Figure 2 As shown, if the display section 12, such as the production date, displayed at the end of the toothpaste tube 11 is oriented toward the opening 25 of the box body 2, the inside of the oral hygiene tool carrying case 1 can be easily identified through the opening 25 while the box body 2 and the cover 3 are closed.

[0044] As described above, the peripheral walls of the main body 2 and the cover 3 of the oral hygiene tool carrying case 1 of the present invention are respectively point-symmetric cross-sectional shapes. On the main body 2, a guide piece 4 extending toward the cover 3 is provided on a portion of the peripheral wall of the main body 2, and a sliding surface 30 that slides along the outer surface of the guide piece 4 is provided on the cover 3. According to the above structure, by utilizing the sliding surface 30 and the guide piece 4, it is possible to easily connect the main body 2 and the cover 3 and to detach the cover 3 from the main body 2.

[0045] Furthermore, on the sliding surface 30 of the cover 3, a first locking part 31 is provided at a first connection position that locks the box body 2 and the cover 3 together, and a second locking part 32 is provided at a second connection position that separates the box body 2 and the cover 3 by a certain distance. On the outer surface of the guide plate 4, a locked part 44 is provided that allows the first locking part 31 or the second locking part 32 to be selectively locked. By causing the relative displacement (rotation) of the angular positions of the box body 2 and the cover 3, the state of the first locking part 31 facing the locked part 44 and the state of the second locking part 32 facing the locked part 44 are switched. Therefore, it has the following advantages: the air permeability of the oral cleaning tool carrying box 1 is fully ensured as needed, and the airtightness of the oral cleaning tool carrying box 1 is maintained.

[0046] That is, when the moistened oral hygiene product 10 is placed into the oral hygiene product carrying case 1, if the second locking part 32 of the cover 3 is engaged with the locked part 44 of the case body 2, it will... Figure 3 When the device is positioned at the second connection point that separates the main body 2 and the cover 3 by a certain distance, the gap 43 formed between the two guide plates 4, 4 is exposed between the main body 2 and the cover 3. As a result, a vent is formed between the cover 3 and the main body 2, allowing the oral hygiene tool carrying case 1 to communicate with the inside and outside, thus ensuring sufficient air permeability. Consequently, the oral hygiene tool 10, consisting of a toothbrush or the like, stored inside the oral hygiene tool carrying case 1 can be effectively dried, preventing it from remaining damp for extended periods.

[0047] On the other hand, when carrying the oral hygiene tool carrying case 1 containing the oral hygiene tool 10 in a bag or similar container, the first locking part 31 of the cover 3 is engaged with the locking part 44 of the case body 2, as if... Figure 2 The device is positioned at the first connection point that seals the body 2 and the lid 3, thereby preventing the gap 43 of a predetermined width formed between the two guide pieces 4, 4 from being exposed between the body 2 and the lid 3. Therefore, it effectively prevents moisture, dust, or debris leaking from the oral hygiene product carrying case 1 from contaminating the product or similar items and entering the case.

[0048] Furthermore, with the main body 2 and the lid 3 sealed, an opening 25 is formed on the main body 2 to allow identification of the interior of the oral hygiene product carrying case 1. In this case, the contents of the oral hygiene product carrying case 1 can be identified through the opening 25 without the lid 3 detaching from the main body 2. Moreover, it has the advantage that even with the main body 2 and lid 3 sealed, the interior and exterior of the oral hygiene product carrying case 1 are still connected through the opening 25, thereby ensuring a certain degree of breathability. Furthermore, when carrying the oral hygiene product carrying case 1 in a bag or similar item, if the opening 25 faces upwards, moisture inside the oral hygiene product carrying case 1 will not leak into the bag. Alternatively, the opening 25 can be covered with a transparent sheet or plate, allowing the interior of the oral hygiene product carrying case 1 to be identified while completely cutting off the connection between the interior and exterior.

[0049] In the above embodiment, the opening 25, which is formed by a cut extending along the gap 43 between adjacent guide pieces 4, 4, is located near the upper part of the box body 2. However, a window-shaped opening at a different location from the gap 43 can be used instead of this structure. However, as described above, when the gap 43 between the two adjacent guide pieces 4, 4 extending upward from the upper opening of the box body 2 and the opening 25 formed by the cut are continuous, demolding during the formation of the box body 2 by injection molding or the like can be facilitated, and the manufacturing cost of the oral hygiene product carrying box 1 can be kept low.

[0050] In addition, such as Figure 4 As shown, the guide plate 4 is formed with a flat portion 41 extending upward along the sidewall portions 21 and 22 of the box body 2 and a pair of bent portions 42 continuously provided on its left and right sides. The cross-section is approximately shaped like the Japanese kana character "コ". In this case, it has the following advantages: by providing the reinforcing effect of the bent portions 42, its strength and rigidity can be effectively improved without increasing the thickness of the guide plate 4. Furthermore, the bent portions 42 do not need to be continuously provided on the left and right sides of the flat portion 41, and one or both of the bent portions 42 can be omitted.

[0051] In the above embodiment, a pair of guide plates 4 are provided opposite to each other on the box body 2. However, a pair of guide plates extending downward from the lower end of the lid 3 can also be provided instead of this structure. However, when the guide plates are provided on the lid 3, they may become an obstacle when using the lid 3 as a rinsing cup. In contrast, as shown in the above embodiment, when the guide plates 4 are provided on the box body 2, the lid 3 can be conveniently used as a rinsing cup when it is detached from the box body 2.

[0052] As shown in the above embodiment, a first locking portion 31, which is composed of protrusions, is formed near the lower end of the cover body 3, and a second locking portion 32, which is composed of protrusions, is formed at a predetermined distance from the lower end of the cover body 3, on the inner surface of the peripheral wall portion of the cover body 3. According to the above structure, when the cover body 3 is used as a gargling cup, both the first locking portion 31 and the second locking portion 32 can be used as markings for injecting gargling solution or for diluting gargling solution, etc., thus further improving the utilization value of the cover body 3.

[0053] Furthermore, in the above embodiment, the first and second locking portions 31 and 32 are formed by protrusions, and the engaged portion 44, which selectively engages the first and second locking portions 31 and 32, is formed by recesses. However, this is not limited to this, and various modifications can be made. For example, the first and second locking portions 31 and 32 may be formed by recesses, and the engaged portion 44 may be formed by protrusions embedded in the first and second locking portions 31 and 32. In addition, when the cover 3 and the box body 2 are connected by protrusions, the guide piece 4 may be elastically deformed, allowing the protrusions forming the first and second locking portions 31 and 32 to pass over the protrusions forming the engaged portion 44, thereby engaging the two protrusions with each other.

[0054] Furthermore, as described above, the peripheral walls of the box body 2 and the lid 3 are approximately square in cross-sectional shape, that is, approximately square with equal lengths on one side and rounded corners. Guide plates 4 are provided with a flat portion 41 extending upward from one side wall portion 21 constituting the peripheral wall portion of the box body 2 and a pair of left and right bent portions 42 provided on its left and right sides. Guide plates 4 are provided with a flat portion 41 extending upward from the other side wall portion 22 opposite to the aforementioned one side wall portion 21 and a pair of left and right bent portions 42 provided on its left and right sides. In this structure, the following advantages are available: the operation of connecting or disconnecting the lid 3 and the box body 2 can be performed smoothly, and the breathability of the oral hygiene tool carrying box 1 can be fully ensured as needed.

[0055] That is, when the cover 3 is connected to the box body 2, the cover 3 can be supported by a pair of guide plates 4, 4 provided at the upper end of the box body 2, and the sliding surface 30 of the cover 3 can be smoothly slid along the outer surfaces of the two guide plates 4, 4. Moreover, by making the opening area of ​​the gap 43 formed between the two guide plates 4, 4 large, the air permeability of the oral cleaning tool carrying box 1 can be sufficiently ensured when the second locking part 32 of the cover 3 is locked with the locking part 44 of the box body 2.

[0056] In addition, instead of the above embodiment in which the peripheral walls of the box body 2 and the lid 3 are approximately square cross-sectional shapes, the peripheral walls of the box body 2 and the lid 3 can be point-symmetric cross-sectional shapes composed of rectangles, triangles, hexagons or ellipses, etc., so that the angular positions of the box body 2 and the lid 3 are relatively displaced, thereby causing the first locking part 31 or the second locking part 32 to selectively face the locking part 44.

[0057] For example, such as Figures 7-9 As shown, the peripheral walls of the box body 2a and the lid 3a can also be made into corresponding rectangular cross-sectional shapes. Furthermore, a structure can be provided with a first locking part 31 on the side wall part 33a and the side wall part 36a orthogonal to it, and a second locking part 32 on the side wall part 34a opposite to the side wall part 33a and the side wall part 35a orthogonal to it. Moreover, a structure can be provided with a locking part 44 on the outer surface of the guide piece 4a extending upward from the upper end of the side wall part 21a and the side wall part 24a orthogonal to it of the box body 2a.

[0058] According to this structure, if the cover 3a and the box body 2a are connected with the side wall portions 33a and 36a of the cover 3a having the first locking portion 31 facing the side wall portions 21a and 24a of the box body 2a having the locking portion 44, the cover 3a will lock at the first connection position that makes the box body 2a and the cover 3a fit together.

[0059] Furthermore, if the lid 3a and the box body 2a are connected when the box body 2a and the lid 3a are moved (rotated) 180 degrees relative to each other from the aforementioned facing state, such that the side wall portions 34a and 35a of the lid 3a, which are provided with the second locking portion 32, are facing the side wall portions 21a and 24a of the box body 2a, which are provided with the engaging portion 44, then the lid 3a and the box body 2a are locked at a second connection position that separates the box body 2a and the lid 3a by a certain distance. At this second connection position, a connecting hole is formed in the upper part of the side wall portions 22a and 23a, where the guide piece 4a is not provided between the box body 2a and the lid 3a, allowing communication between the inside and outside of the oral hygiene tool carrying box.

[0060] Figure 10 and Figure 11This embodiment illustrates an embodiment where the peripheral walls of the box body 2b and the lid 3b have a triangular cross-sectional shape. Furthermore, a first locking portion 31 is provided on one side wall 33b constituting the peripheral wall of the lid 3b, engaging at a first connection position that seals the lid 3b with the upper opening of the box body 2b. Additionally, a second locking portion 321, with a smaller separation distance from the lower end of the lid 3b, is provided on the other side wall 34b of the lid 3b, and a third locking portion 322, with a larger separation distance from the lower end of the lid 3b, is provided on the other side wall 35b of the lid 3b. Moreover, an engaging portion 44 is provided on the outer surface of the guide piece 4b extending upward from the upper end of the side wall 21b of the box body 2b, selectively engaging any one of the first locking portions 31, the second locking portion 321, and the third locking portion 322.

[0061] According to this structure, if the cover 3b and the box body 2b are connected with the side wall portion 33b of the cover 3b having the first locking portion 31 facing the side wall portion 21b of the box body 2b having the locking portion 44, the cover 3b can be locked at the first connection position where the lower end of the cover 3b is sealed to the upper opening of the box body 2b.

[0062] Furthermore, from the aforementioned opposing state, the cover 3b along Figure 11 Rotating 120 degrees counterclockwise, if the cover 3b and the box body 2b are connected with the side wall 34b of the cover 3b having the second locking part 321 facing the side wall 21b of the box body 2b having the engaging part 44, the cover 3b can be locked at a second connection position where the lower end of the cover 3b and the upper opening of the box body 2b are separated by a certain distance.

[0063] Furthermore, from the aforementioned opposing state, the cover 3b is rotated 120 degrees counterclockwise (from... Figure 10 and Figure 11 (Rotated 240 degrees as shown), if the cover 3b and the box body 2b are connected with the side wall 35b of the cover 3b, which has the third locking part 322, facing the side wall 21a of the box body 2b, which has the engaging part 44, the cover 3b can be locked in a third connection position that increases the separation distance between the box body 2b and the cover 3b. As a result, the size of the connecting hole formed between the box body 2b and the cover 3b can be varied in two stages.
