Description

[Technical field]

[0001] The present invention relates to a cap opener for opening and closing a cap of a container. [Background technology]

[0002] There are known cap openers that allow even elderly people and others with weak grip strength to easily open and close the caps of containers such as plastic bottles. Generally, such cap openers are not considered to be necessities of life, and are easily forgotten when going out, and people may have difficulty opening the caps of containers when they are out. Therefore, the applicant of the present application has proposed a technology for attaching a cap opener to a portable item (see Patent Document 1).

[0003] This technology can reduce the risk of forgetting to take the cap opener. However, when the portable item is a smartphone, which has a shape significantly different from that of a general cap opener, verification results have shown that, due to sensory differences, there are many cases where the cap is rotated in the direction of closing, even when attempting to open the cap. In this case, a large load acts on the cap opener, which may cause damage. In addition, when opening a cap with only the fingers, for example, the left hand holds the container and holds it in place, and the right hand opens the cap. In contrast, in the above technology, when the cap opener is attached to a smartphone, if the left hand holds the container and the right hand rotates the smartphone to open the cap, it is difficult to open the cap unless both the container and the smartphone are changed during the operation due to the dimensions and shape of the smartphone. Furthermore, in the above technology, the cap opener can also be used as a smartphone stand. However, when the cap opener is attached to the smartphone, the positional relationship between the smartphone and the member of the cap opener to which the smartphone is attached is fixed. Therefore, depending on the relative positions of these devices, when the cap opener is used as a smartphone stand, the smartphone screen is tilted, and the smartphone cannot be rotated relative to the cap opener even if one wishes to do so. Therefore, the cap opener must be reattached to the smartphone, or, if a bonding method that does not allow reattachment is used, the bonding work must be done carefully. As mentioned above, there is still room for improvement. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2023-96452 ​​A Summary of the Invention [Problem to be solved by the invention]

[0005] An object of the present invention is to provide a cap opening / closing device that is easy to use and reduces the risk of forgetting to carry it. [Means for solving the problem]

[0006] The present invention employs the following means to solve the above problems.

[0007] The cap opening and closing device of the present invention is an annular portion having a first opening that can be fitted to a cap of a container and can be engaged in a rotational direction to open and close the cap; a storage section having a second opening capable of storing the annular section; The annular portion and the storage portion are connected while allowing the annular portion to be stored in the second opening and to be spaced apart from the second opening. The connecting part and A mounting portion that is connected to the storage portion and is attached to a portable item; Equipped with When the annular portion is housed in the second opening, the annular portion and the housing portion are engaged with each other in the rotational direction, The present invention is characterized in that a ratchet mechanism is provided that limits the rotation direction of the storage portion relative to the mounting portion to one direction.

[0008] According to the present invention, the cap opening / closing tool is attached to the portable item by attaching the attached part to the portable item. This reduces the possibility of forgetting to take the cap opening / closing tool. In addition, since the annular part is connected to the storage part by the connecting part, the portable item can be prevented from falling when the portable item is held by hand and used by hooking a finger on the first opening of the annular part. In addition, when the annular part is stored in the second opening, the annular part and the storage part are engaged in the rotation direction, so that when opening and closing the cap, the cap can be opened by applying force to the portable item while holding it. Furthermore, by providing a ratchet mechanism, the storage part can be rotated only in a desired direction relative to the attached part, and rotation in the other direction can be restricted. Accordingly, the portable item can also be rotated relative to the annular part and the storage part.

[0009] An engagement structure is provided that restricts movement of the storage portion and the mounting portion in a direction away from each other and allows movement in a direction of relative rotation, and it is preferable that the ratchet mechanism be provided separately from the engagement structure.

[0010] This allows the storage portion and the attached portion to be rotated relative to each other while maintaining the engagement between them.

[0011] The ratchet mechanism is composed of a plurality of ratchet pawls provided on one of the storage portion and the mounting portion, and at least one ratchet piece provided on the other of the storage portion and the mounting portion. When the storage portion rotates in one direction relative to the mounting portion, the ratchet piece overcomes the ratchet pawl, and when the storage portion attempts to rotate in the other direction, the ratchet piece engages with the ratchet pawl, thereby restricting the rotation.

[0012] The ratchet piece is preferably provided so as to be capable of bending and deforming in a radial direction, and the ratchet piece and the ratchet pawl are preferably provided so as to be capable of sliding on their peripheral surfaces relative to each other.

[0013] The storage portion is an annular member, and a plurality of the ratchet pawls are provided on an inner peripheral surface side along the entire circumference thereof. The mounting portion may be provided with a plurality of ratchet pieces spaced apart in the circumferential direction and arranged to fit inside a portion of the annular storage portion where the ratchet pawls are provided.

[0014] The ratchet piece is preferably arranged to be capable of flexibly deforming in a direction parallel to a central axis of rotation of the storage section relative to the mounting section, and the ratchet piece and the ratchet pawl are preferably arranged so that opposing surfaces thereof can slide against each other.

[0015] Furthermore, when viewed from the storage portion in a direction toward the attached portion, it is preferable that the storage portion be restricted from rotating in a counterclockwise direction relative to the attached portion. In this way, in the case of a typical container cap, the relative rotation between the storage portion and the attached portion is restricted in the direction in which the cap is opened, so the cap can be opened. On the other hand, in the direction in which the cap is closed, the storage portion and the attached portion rotate freely, so the cap opening and closing is difficult. This can prevent a large load from being applied to the tool.

[0016] The above configurations may be combined as much as possible. Effect of the Invention

[0017] As described above, according to the present invention, it is possible to prevent a user from forgetting to take the cap opener with him / her, and the cap opener is easy to use. [Brief description of the drawings]

[0021] <Cap opening and closing device configuration> The cap opening / closing device 10 according to this embodiment includes an annular member 100 as an annular portion, a storage member 200 as a storage portion, and an axis member 400 as a connecting portion connecting the annular member 100 and the storage member 200. The cap opening / closing device 10 according to this embodiment also includes a mounting member 300 as a mounting portion that is connected to the storage member 200. As the material for the annular member 100, the storage member 200, and the mounting member 300, a resin material (such as high-density polyethylene, polypropylene, polycarbonate, etc.) can be suitably used.

[0022] The annular member 100 is provided with a through hole 110 as a first opening that can be fitted into a cap 720 attached to a container body 710 of the container 700 and can be engaged in a rotational direction that opens and closes the cap 720. In this embodiment, the inner peripheral surface of the through hole 110 is configured as a substantially cylindrical surface. The inner peripheral surface of the through hole 110 is provided with a plurality of knurled portions 111 that can be engaged in a rotational direction that opens and closes the cap 720 with a plurality of knurled portions 721 formed in the circumferential direction on the outer peripheral surface of the cap.

[0023] The storage member 200 is provided with a second opening 205 capable of storing the annular member 100. The annular member 100 is provided with a protruding portion 120, and the storage member 200 is provided with a pair of clamping portions 210 that are provided to sandwich the protruding portion 120 from both sides. The protruding portion 120 and the pair of clamping portions 210 are provided with shaft holes 121, 211 that communicate with each other. The shaft member 400 is inserted into these shaft holes 121, 211. It is preferable to use a hard material such as metal for the shaft member 400. In FIG. 1, these configurations are shown in dotted lines in a see-through manner. With the above configuration, the annular member 100 can be rotated relative to the storage member 200 around the central axis of the shaft member 400. Therefore, it is possible to take a state in which the annular member 100 is stored in the second opening 205 and a state in which the annular member 100 is separated from the second opening 205. FIG. 1(b) shows the former state, and FIG. 1(c) shows the latter state.

[0024] The annular member 100 according to this embodiment is provided with a handle portion 130. The storage member 200 is provided with a groove portion 220 that stores the portion of the handle portion 130 excluding a part of the tip.

[0025] As described above, the annular member 100 and the storage member 200 are connected by the shaft member 400, and the handle portion 130 is stored in the groove portion 220, so that when the annular member 100 is stored in the storage member 200, the relative rotation therebetween is restricted.

[0026] In this embodiment, the bottom surface 305 of the attachment member 300 connected to the storage member 200 is attached to the portable item 600. As a result, the cap opening / closing device 10 is attached to the portable item 600. Various known techniques can be applied to attach the attachment member 300 to the portable item 600. For example, an attachment method using adhesive or double-sided tape can be adopted, and adhesive or the like can be provided in advance on the bottom surface 305 of the attachment member 300, or the attachment can be performed using adhesive or double-sided tape separately. Also, an adhesion method that assumes that the attachment member will not be peeled off once it is attached to the portable item 600 may be adopted, or an adhesion (adhesion) method that assumes that adhesion and peeling are repeated may be adopted. Note that the ratchet piece 320 provided on the attachment member 300 described later is provided at a position away from the bottom surface 305 of the attachment member 300. As a result, the ratchet piece 320 is not adhered to the portable item 600.

[0027] The cap opening / closing device 10 according to this embodiment is provided with a ratchet mechanism that restricts the rotation direction of the storage member 200 to one direction relative to the attachment member 300. The above-mentioned ratchet mechanism and an engagement structure that restricts the movement of the storage member 200 and the attachment member 300 in the direction away from each other and allows movement in the direction of relative rotation are also provided. The ratchet mechanism and the engagement structure will be described in detail below.

[0028] The ratchet mechanism is composed of a plurality of ratchet pawls provided on one of the storage member and the attached member, and at least one ratchet piece provided on the other. In this embodiment, a structure is adopted in which the ratchet pawl 240 is provided on the storage member 200, and the ratchet piece 320 is provided on the attached member 300. However, a structure in which the ratchet piece is provided on the storage member, and the ratchet pawl is provided on the attached member may also be adopted. The ratchet pawl 240 is configured to have high rigidity and is difficult to deform, and the ratchet piece 320 is flexible. In the illustrated example, as shown in FIG. 4(a), the plurality of ratchet pieces 320 are provided on the upper surface of a plurality of overhang pieces 325 extending radially inward, so as to be connected to the inner tips in the radial direction, respectively. The ratchet piece 320 is configured to extend at an angle radially outward from the connection position with the overhang piece 325.

[0029] With the above configuration, when the storage member 200 rotates in one direction relative to the mounting member 300, the ratchet piece 320 climbs over the ratchet pawl 240, and when it attempts to rotate in the other direction, the ratchet piece 320 engages with the ratchet pawl 240, restricting the rotation. In this embodiment, the ratchet piece 320 is provided so as to be capable of bending and deforming in the radial direction, and the ratchet piece 320 and the ratchet pawl 240 are provided so that their peripheral surfaces can slide against each other.

[0030] More specifically, the storage member 200 is an annular member, and a plurality of ratchet pawls 240 are provided around the entire circumference on the inner peripheral surface side (see FIG. 3(c)). The attached member 300 is provided with a plurality of ratchet pieces 320 spaced apart in the circumferential direction, which are arranged so as to enter inside the portion of the annular storage member 200 where the plurality of ratchet pawls 240 are provided (see FIGS. 4 and 5). With the above configuration, the storage member 200 is restricted from rotating in the counterclockwise direction relative to the attached member 300 when viewed from the storage member 200 to the attached member 300. That is, when the storage member 200 is rotated in the counterclockwise direction relative to the attached member 300, the ratchet piece 320 engages with the ratchet pawl 240, and the rotation is restricted. On the other hand, when the storage member 200 is rotated in the clockwise direction relative to the attached member 300, the ratchet piece 320 rides over the ratchet pawl 240. Therefore, if the ratchet piece 320 and the ratchet pawl 240 are rotated with a force at least greater than the sliding resistance between their peripheral surfaces, the storage member 200 can be rotated (idled) relative to the mounting member 300.

[0031] In this embodiment, as described above, the storage member 200 and the attached member 300 are provided with an engagement structure that restricts movement in the direction away from each other and allows movement in the direction of relative rotation. More specifically, in this embodiment, the bottom surface side of the storage member 200 is provided with engagement protrusions 230 over approximately the entire circumference, and the top surface side of the attached member 300 is provided with multiple engaged protrusions 310 spaced apart in the circumferential direction. With the above configuration, the bottom surface of the storage member 200 and the top surface of the attached member 300 are pressed against each other in a state where they face each other, and the engagement protrusions 230 and the multiple engaged protrusions 310 are engaged with each other. As a result, the storage member 200 and the attached member 300 are restricted from moving in the direction away from each other and allowed to move in the direction of relative rotation.

[0032] In the cap opener / closer 10 according to this embodiment, as shown in each drawing, an engagement structure is provided on the outer peripheral surface side, and a ratchet mechanism is provided on the inner peripheral surface side of the engagement structure. However, the present invention is not limited to such a configuration, and a configuration in which a ratchet mechanism is provided on the outer peripheral surface side, and an engagement structure is provided on the inner peripheral surface side of the ratchet mechanism may also be adopted.

[0033] <Advantages of the cap opening / closing device according to this embodiment> Since the cap opening / closing device 10 according to this embodiment is attached to the portable item 600, it is possible to reduce the likelihood of forgetting to carry the cap opening / closing device 10. In other words, by attaching the cap opening / closing device 10 to the portable item 600 that the user carries with him / her at all times, it is possible to reduce the likelihood of forgetting to carry the cap opening / closing device 10. Specific examples of the portable item 600 include smartphones, mobile phones, portable game consoles, hand mirrors, compact mirrors, card cases, and remote controls for televisions and air conditioners. It is also preferable to attach the cap opening / closing device 10 to the case of a smartphone or the like.

[0034] Moreover, the annular member 100 is connected to the storage member 200 by the shaft member 400, which is a connecting portion. Furthermore, the storage member 200 and the attached member 300 are connected to each other. Therefore, by hooking a finger on the through hole 110 in the annular member 100, it is possible to prevent the portable item 600 from falling when the portable item 600 is held by hand. This allows the cap opening / closing device 10 to function as a smartphone ring, for example, when the portable item 600 is a smartphone. Furthermore, by hanging the through hole 110 on a hook or the like, the portable item 600 can be hung on a wall or the like.

[0035] When the cap 720 of a container 700 such as a plastic bottle is opened using the cap opening / closing device 10 according to this embodiment, the cap 720 can be easily opened in a state where the annular member 100 is stored in the second opening 205. FIG. 6(a) shows a state when the cap 720 is opened. In the illustrated state, the cap 720 can be opened by holding the container body 710 of the container 700 with one hand and rotating the portable item 600 while holding it with the other hand. In this embodiment, as described above, since a ratchet mechanism is provided, when the portable item 600 is rotated counterclockwise relative to the container 700, a rotational force is transmitted from the attachment member 300 to the storage member 200 and the annular member 100, and the cap 720 rotates. On the other hand, when the portable item 600 is rotated clockwise relative to the container 700, the attachment member 300 and the storage member 200 rotate idly, so that no rotational force is transmitted to the cap 720. Therefore, while holding the container 700 in place with one hand, the user can rotate the portable item 600 counterclockwise and clockwise with the other hand to open the cap 720. Furthermore, when rotating the portable item 600 clockwise with respect to the container 700, the attachment member 300 and the storage member 200 rotate freely, so that even if the portable item 600 is rotated with a large force in the direction to close the cap 720 by mistake, it is possible to prevent a large load from being applied to the cap opening / closing device 10.

[0036] Here, as described above, when the storage member 200 is rotated clockwise relative to the attached member 300, the ratchet piece 320 and the ratchet claw 240 rotate with a force greater than or equal to the sliding resistance between the circumferential surfaces of the ratchet piece 320 and the ratchet claw 240, and they rotate freely. Therefore, by setting this sliding resistance to a predetermined value or less, as described above, the cap 720 can be opened by holding the container 700 in one hand and repeatedly moving the portable item 600 in the counterclockwise and clockwise directions relative to the container 700 with the other hand. However, when such a configuration is adopted, the cap 720 cannot be closed using the cap opening / closing device 10 according to this embodiment. Therefore, if it is desired to be able to close the cap 720 using the cap opening / closing device 10 according to this embodiment, the sliding resistance may be set to a predetermined value or more. However, if this sliding resistance is made too large, a large load acts on the cap opening / closing device 10, so it is necessary to set the sliding resistance to an appropriate value. In addition, when such a configuration is adopted, the cap 720 cannot be opened by holding the container 700 in place with one hand and repeatedly moving the portable item 600 in a counterclockwise and clockwise direction with respect to the container 700 with the other hand. Therefore, depending on the dimensions and shape of the portable item 600, it may be necessary to switch the container 700 and the portable item 600 during the operation.

[0037] In addition, the attachment member 300 is attached to the portable item 600 having a weight of less than a predetermined weight, and the annular member It is also preferable that the annular member 100 and the storage member 200 can be held in any positional relationship when the annular member 100 is fitted into the cap 720 of the container 700 placed on a horizontal installation surface. More specifically, it is preferable to set the frictional force generated between the outer circumferential surface of the shaft member 400 and the inner circumferential surfaces of the shaft holes 121, 211 provided in the annular member 100 and the storage member 200 to a high value within a range that does not hinder the rotational movement of the annular member 100 relative to the storage member 200.

[0038] By adopting the above configuration, the portable item 600 can be attached to the container 700, and the orientation of the portable item 600 relative to the container 700 can be held in a desired state. FIG. 6(b) shows a state in which the portable item 600 is placed in the container 700 and held at a predetermined angle of inclination. For example, if the portable item 600 is a smartphone, the maximum weight is about 300 g. Therefore, if the above "predetermined weight" is set to 300 g and the above frictional force is set, the smartphone can be placed in the container 700 at a desired inclination. That is, the container 700 can be used as a smartphone stand. Of course, even if the portable item 600 is a portable game console, a hand mirror, or the like, the container 700 can be used as a stand. It goes without saying that if the above frictional force is set as above, the portable item 600 can be placed directly on a placement surface such as a table at a desired inclination. In this embodiment, since the storage member 200 can be rotated relative to the attachment member 300, the portable item 600 can be rotated relative to the container 700 while the portable item 600 is fixed to the container 700. Therefore, for example, when used as a smartphone stand, the position of the rotation direction of the smartphone screen can be adjusted to a desired position. Therefore, it is not necessary to be very careful when attaching the attachment member 300 to the portable item 600, and it is easy to use.

[0039] Example 2 7 to 9 show a second embodiment of the present invention. In the first embodiment, the ratchet piece is provided so as to be capable of bending and deforming in the radial direction, and the ratchet piece and the ratchet pawl are provided so as to be slidable along their circumferential surfaces. In contrast, in the present embodiment, the ratchet piece is provided so as to be capable of bending in the vertical direction (the direction parallel to the central axis of rotation of the storage part relative to the mounting part), and the ratchet piece and the ratchet pawl are provided so as to be slidable along their opposing surfaces. The configuration other than the ratchet mechanism and the engagement structure is the same as that described in the first embodiment, and therefore description thereof will be omitted.

Fig. 1(c) shows the storage member and a part of the inner circumferential surface of the attached member, and the storage member is shown in a see-through manner with the parts necessary for explanation indicated by dotted lines.

[0041] The cap opener according to this embodiment also includes an annular member as an annular portion, a storage member 200A as a storage portion, a connecting portion connecting the annular member and the storage member 200A, and a mounting member 300A as a mounting portion connected to the storage member 200A. The annular member and the connecting portion are the same as those described in the first embodiment, and therefore the description thereof will be omitted.

[0042] The storage member 200A according to this embodiment also has a second opening 205A capable of storing the annular member. In this embodiment, as in the first embodiment, the storage member 200A also has a pair of clamping parts arranged to clamp the protruding part of the annular member from both sides, and a groove part for storing a part of the handle part of the annular member except for a part of the tip. These are the same as in the first embodiment, so illustration and description thereof are omitted. As described in the first embodiment, various configurations can be adopted for the configuration of the connecting part between the storage member 200A and the annular member. Furthermore, in this embodiment, the bottom surface of the attachment member 300A connected to the storage member 200A is attached to the portable item. As a result, the cap opening and closing tool is attached to the portable item. The method of attaching the attachment member 300A to the portable item is as described in the first embodiment.

[0043] The cap opener according to this embodiment also has a ratchet mechanism that restricts the rotational direction of the storage member 200A to the mounting member 300A in one direction. In addition to the ratchet mechanism, an engagement structure is provided that restricts the storage member 200A and the mounting member 300A from moving in the direction away from each other and allows movement in the direction of relative rotation. The ratchet mechanism and engagement structure will be described in detail below.

[0044] The ratchet mechanism is composed of a plurality of ratchet pawls provided on one of the storage member and the attached member, and at least one ratchet piece provided on the other. In this embodiment, as shown in Fig. 7, a structure is adopted in which a ratchet pawl 240A is provided on the storage member 200A, and as shown in Fig. 8, a ratchet piece 320A is provided on the attached member 300A. However, a structure in which a ratchet piece is provided on the storage member and a ratchet pawl is provided on the attached member may also be adopted. The ratchet pawl 240A is configured to be highly rigid and difficult to deform, and the ratchet piece 320A is flexible.

[0045] With the above configuration, when the storage member 200A rotates in one direction relative to the mounting member 300A, the ratchet piece 320A passes over the ratchet pawl 240A, and when it tries to rotate in the other direction, the ratchet piece 320A engages with the ratchet pawl 240A, restricting the rotation. In this embodiment, the ratchet piece 320 is provided so as to be able to bend and deform in the up-down direction, and the ratchet piece 320 and the ratchet pawl 240 are provided so that their opposing surfaces can slide against each other.

[0046] In this embodiment, the storage member 200A is an annular member, and a plurality of ratchet pawls 240A are provided around the entire circumference on the back side. The attached member 300A is provided with a plurality of ratchet pieces 320A at intervals in the circumferential direction, which are arranged at positions facing the portion of the storage member 200A where the plurality of ratchet pawls 240A are provided (see FIG. 9). With the above configuration, when viewed from the storage member 200A to the attached member 300A, the storage member 200A is restricted from rotating in the counterclockwise direction relative to the attached member 300A. That is, when the storage member 200A is rotated in the counterclockwise direction relative to the attached member 300A, the ratchet piece 320A engages with the ratchet pawl 240A, and the rotation is restricted. On the other hand, when the storage member 200A is rotated in the clockwise direction relative to the attached member 300A, the ratchet piece 320A rides over the ratchet pawl 240A. Therefore, by rotating with a force at least greater than the sliding resistance between the opposing surfaces of the ratchet piece 320A and the ratchet pawl 240A, the storage member 200A can be rotated (idled) relative to the mounting member 300A.

[0047] In this embodiment, the storage member 200A and the mounting member 300A are provided with an engagement structure that restricts the movement of the storage member 200A and the mounting member 300A in a direction away from each other, but allows the movement of the storage member 200A in a direction of relative rotation. The side of the mounting member 300A is provided with engaging protrusions 230A over substantially the entire circumference, and the top side of the mounting member 300A is provided with multiple engaged protrusions 310A spaced apart in the circumferential direction. With the above configuration, the bottom surface of the storage member 200A and the top surface of the mounting member 300A are opposed to each other, and when they are pressed against each other, the engaging protrusions 230A and the multiple engaged protrusions 310A are engaged with each other. As a result, the movement of the storage member 200A and the mounting member 300A in the direction away from each other is restricted, and movement in the direction of relative rotation is permitted.

[0048] The cap opening / closing device according to this embodiment configured as above can also provide the same effects as those of the first embodiment.

[0049] In the cap opening / closing device according to the present embodiment, as shown in each drawing, a configuration is adopted in which an engagement structure is provided on the outer peripheral surface side, and a ratchet mechanism is provided on the inner peripheral surface side of the engagement structure. However, the present embodiment is not limited to such a configuration, and a configuration in which a ratchet mechanism is provided on the outer peripheral surface side, and an engagement structure is provided on the inner peripheral surface side of the ratchet mechanism may also be adopted. Such a configuration will be briefly described with reference to Fig. 10. Fig. 10 is an explanatory diagram of a storage member and a mounted member according to a modified example of the second embodiment of the present invention, in which Fig. 10(a) is a part of a bottom view of the storage member (storage section), and Fig. 10(b) is a part of a plan view of the mounted member (mounted section).

[0050] In this modification, the storage member 200B is provided with a ratchet pawl 240B and an engaging projection 230B, and the attached member 300B is provided with a ratchet piece 320B and an engaged projection 310B. The ratchet mechanism and the engaging structure themselves can be configured similarly to those in the second embodiment, and therefore will not be described here. This modification differs from the second embodiment only in that the ratchet mechanism is provided on the outer circumferential surface side, and the engaging structure is provided on the inner circumferential surface side of the ratchet mechanism.

[0051] (others) In the above-mentioned embodiment 1, the case where the connecting part is configured by the shaft member 400 has been shown, but the connecting part in the present invention is not limited to such a configuration. For example, a universal joint (such as a ball joint) can be used for the connecting part. In addition, in the above-mentioned embodiment, the case where the annular part (annular member) and the storage part (storage member) are configured by different members has been shown, but a configuration in which the annular part and the storage part are integrally provided by a hinge part can be adopted. In this case, the shaft member is not necessary, and the annular part, the storage part, and the hinge part can be integrally molded. Furthermore, a configuration in which the storage member shown in each of the above-mentioned embodiments is integrally provided on the smartphone case can also be adopted. That is, the storage member shown in each of the above-mentioned embodiments is configured by a ring-shaped member, but for example, by providing the smartphone case with an axis hole for inserting the shaft member 400, an engagement structure, and a ratchet mechanism, it is possible to give the smartphone case the function as the storage member of the present invention.
