[0004] However, in conventional containers, the container body must be firmly attached to the lid to prevent it from falling off, which poses the problem of laborious attachment and detachment of the container body, and also the risk of liquid spilling from the container body when detaching it from the lid.

[0005] The present invention relates to a holding member and a container that facilitates attachment and detachment of a container body and is capable of preventing liquid from spilling from the container body when the container body is detached. [Means for solving the problem]

[0006] The holding member of the present invention is a holding member that is rotatably provided relative to either the container body or the lid portion, and is used to maintain the attached state of the lid portion relative to the container body, and is provided with an insertion groove into which a protrusion provided on the other of the container body or the lid portion can be inserted, the insertion groove extending in a circumferential direction centered on the rotation axis of the holding member, and is configured so that by sliding the protrusion along the insertion groove, the relative rotational movement of the holding member relative to the container body and the lid portion can be converted into a linear movement that moves the container body and the lid portion closer to or further apart, and the insertion groove has a length that allows the protrusion to be positioned within the insertion groove when the container body and the lid portion are switched between the attached state and the non-attached state.

[0007] In the holding member of the present invention, the insertion groove has a first wall surface portion extending in a circumferential direction centered on the rotation axis of the holding member, and the holding member is configured to be able to convert the relative rotational motion into the linear motion by sliding the protrusion portion along the first wall surface portion, and the first wall surface portion may have a length that allows the protrusion portion to be positioned on the first wall surface portion when the container body and the lid portion switch from the attached state to the detached state.

[0008] In the retaining member of the present invention, the insertion groove may have an open end for inserting the protrusion into the insertion groove, and the first wall surface portion may have a curved surface portion that curves from the inside of the insertion groove toward the open end.

[0009] In the holding member of the present invention, the insertion groove may have a second wall surface portion opposite the first wall surface portion, and the holding member may be configured to be able to convert the relative rotational motion into a linear motion that brings the container body and the lid portion closer together by sliding the protrusion portion along the second wall surface portion.

[0010] The container of the present invention comprises a container body having an opening, a lid portion capable of closing the opening of the container body, and a holding member that is rotatable relative to either the container body or the lid portion and maintains the attached state of the lid portion to the container body, and the other of the container body and the lid portion is provided with a protrusion, and the holding member has an insertion groove into which the protrusion can be inserted, the insertion groove extending in a circumferential direction centered on the rotation axis of the holding member, and is configured so that by sliding the protrusion along the insertion groove, the relative rotational movement of the holding member with respect to the container body and the lid portion can be converted into a linear movement that moves the container body and the lid portion closer to or apart from each other, and the insertion groove has a length that allows the protrusion to be positioned within the insertion groove when the container body and the lid portion are switched between the attached state and the non-attached state. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0013] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. Furthermore, in the present embodiments, the scale and dimensions of each component may be exaggerated, and some components may be omitted.

[0014] [Overall configuration of the container] The container according to this embodiment is a container to be attached to an attachment target (not shown). As shown in Figures 1 and 2, the container 1 includes a container body 10 having an opening 13, a lid 20 capable of closing the opening 13 of the container body 10, and a holding member 30 that is rotatable relative to the lid 20 and that maintains the attachment state of the lid 20 to the container body 10.

[0015] In this specification, the term "attached state" refers to a state in which the lid 20 is completely attached to the container body 10, that is, a state in which the container body 10 is fully inserted into the lid 20. The term "unattached state" refers to a state other than the attached state, and includes a state in which the lid 20 is completely removed from the container body 10 and a state in which the container body 10 is inserted into the lid 20 but not fully inserted.

[0016] Examples of objects to which the device can be attached include, but are not limited to, the housings of hand-washing devices and water treatment devices for home, apartment, commercial, industrial and agricultural use. The device can be widely used in male-female combination mechanisms that are difficult to attach and detach and difficult to pull out or insert.

[0017] [Container body configuration] 1 and 2, the container body 10 has a circular bottom 11 and a cylindrical body side wall 12 extending upward from the periphery of the bottom 11, and is formed as a bottomed cylinder having an opening 13 at its upper end as a whole. The shapes of the bottom 11 and the body side wall 12 are not particularly limited, and various known shapes may be adopted.

[0018] The container body 10 has a storage space 14 capable of storing liquid. The storage space 14 is a space defined by the inner surface of the bottom 11 and the inner surface of the body side wall 12. The container body 10 also has a pair of protrusions 15 at the upper end of the body side wall 12. The protrusions 15 are formed to extend from the outer surface of the body side wall 12 radially outward from the body side wall 12.

[0019] [Lid configuration] 1 and 2, the lid 20 has a circular top 21 and a cylindrical lid sidewall 22 extending downward from the periphery of the top 21, and is formed as a cylinder with an open bottom. The lid 20 also has an inner diameter larger than the outer diameter of the container body 10. The shapes of the top 21 and the lid sidewall 22 are not particularly limited, and various known shapes may be adopted.

[0020] The lid portion 20 has a pair of shafts 23 at the upper end of the lid side wall portion 22. The shafts 23 are formed to extend from the outer surface of the lid side wall portion 22 radially outward from the lid side wall portion 22. The lid portion 20 also has a pair of notches 24 at the lower end of the lid side wall portion 22. The notches 24 are formed by cutting out a U-shape from the lower end to the upper end of the lid side wall portion 22, and are large enough to allow the protrusions 15 of the container body 10 to be inserted into them. The shafts 23 and the notches 24 are arranged in parallel in the vertical direction.

[0021] The lid 20 according to this embodiment is configured to airtightly close the opening 13 of the container body 10 by inserting the protrusion 15 of the container body 10 into the notch 24 and fitting the container body 10 until the upper end of the container body 10 contacts the inner surface of the top 21 of the lid 20. While this embodiment has been described as the lid 20 airtightly closing the opening 13 of the container body 10, this is not limitative, and the opening 13 of the container body 10 may be closed non-airtightly. That is, the upper end of the container body 10 does not have to contact the inner surface of the top 21 of the lid 20, and there may be a gap between the outer surface of the body side wall 12 of the container body 10 and the inner surface of the lid side wall 22 of the lid 20.

[0022] [Configuration of holding member] 1 and 2, the holding members 30 are provided at both radial ends of the lid portion 20. The holding member 30 provided at one radial end of the lid portion 20 and the holding member 30 provided at the other radial end of the lid portion 20 have symmetrical shapes, so the following description will only explain the configuration of one of the holding members 30.

[0023] In the following description of this embodiment, the direction in which the holding member 30 is attached to the object to which it is attached will be referred to as "rear," and the direction in which the holding member 30 is removed from the object to which it is attached will be referred to as "front."

[0024] As shown in Figures 3 to 5, the retaining member 30 has a first flat plate portion 31 that is rectangular and elongated in the vertical direction, a second flat plate portion 32 that is rectangular and elongated in the vertical direction and is arranged eccentrically downward at one end of the first flat plate portion 31 in the short direction, and a peripheral wall portion 33 that extends rearward from the peripheries of the first flat plate portion 31 and the second flat plate portion 32, and is formed into a roughly N-shape overall.

[0025] Furthermore, a claw portion 34 extending from the peripheral wall portion 33 is provided at the other end in the short side direction of the first flat plate portion 31. The claw portion 34 is formed in a piece shape extending from the peripheral wall portion 33 outward in the short side direction of the first flat plate portion 31, and has a protrusion portion 34a at its tip that protrudes rearward.

[0026] The holding member 30 according to this embodiment is configured to be attached to an object by connecting the object to the peripheral wall portion 33 and the claw portions 34. The method of connecting the object to the peripheral wall portion 33 and the claw portions 34 is not particularly limited, and various known connecting methods such as engagement or fitting may be used.

[0027] The holding member 30 has an axis insertion portion 40 into which the axis portion 23 provided on the lid portion 20 can be inserted, and an insertion groove 50 into which the protrusion portion 15 provided on the container body 10 can be inserted.

[0028] The shaft insertion portion 40 is provided above the center of the first flat plate portion 31 in the up-down direction, and is formed in a cylindrical shape extending rearward from the rear surface of the first flat plate portion 31. The shaft insertion portion 40 also has an insertion hole 41 into which the shaft portion 23 of the lid portion 20 can be inserted. The insertion hole 41 is a through-hole formed from the front end of the shaft insertion portion 40 (the front surface of the first flat plate portion 31) to the rear end of the shaft insertion portion 40.

[0029] The holding member 30 according to this embodiment is configured to rotatably hold the lid portion 20 by inserting the shaft portion 23 of the lid portion 20 into the insertion hole 41 of the shaft insertion portion 40.

[0030] The insertion groove 50 is formed to extend in the circumferential direction centered on the rotation axis O of the holding member 30. Specifically, the insertion groove 50 is formed from below the center in the up-down direction of the first flat plate portion 31 to the second flat plate portion 32, and is formed to be recessed from the front surface toward the rear surface of the first flat plate portion 31 and the second flat plate portion 32.

[0031] It should be noted that the "rotation axis of the holding member" is the axis of the insertion hole 41 of the shaft insertion portion 40. Furthermore, the "circumferential direction centered on the rotation axis of the holding member" may be a circumferential direction in which the distance from the rotation axis O of the holding member 30 is constant, or may be a circumferential direction in which the distance from the rotation axis O of the holding member 30 is variable.

[0032] The insertion groove 50 has a bottom surface portion 51 extending circumferentially around the rotation axis O of the holding member 30, a first wall surface portion 52 extending forward from the upper edge of the bottom surface portion 51, a second wall surface portion 53 extending forward from the lower edge of the bottom surface portion 51, an open end portion 54 provided at one end in the direction in which the insertion groove 50 extends, and a closed end portion 55 provided at the other end in the direction in which the insertion groove 50 extends.

[0033] The first wall portion 52 and the second wall portion 53 are separated at their ends on the open end 54 side by the open end 54 , and are connected at their ends on the closed end 55 side by the closed end 55 .

[0034] The first wall surface portion 52 is formed to extend in the circumferential direction centered on the rotation axis O of the holding member 30. Specifically, the first wall surface portion 52 has an inclined portion 52a that inclines in a direction that increases the groove width (upward) from the closed end portion 55 toward the open end portion 54, a first curved surface portion 52b that curves in a direction that decreases the groove width (downward) from the inclined portion 52a toward the open end portion 54, and a second curved surface portion 52c that curves in a direction that increases the groove width (upward) from the first curved surface portion 52b (inside the insertion groove 50) toward the open end portion 54.

[0035] The second wall surface portion 53 faces the first wall surface portion 52. Specifically, the second wall surface portion 53 has a first inclined surface portion 53a facing the inclined portion 52a and the first curved surface portion 52b of the first wall surface portion 52, and a second inclined surface portion 53b facing the second curved surface portion 52c of the first wall surface portion 52. The first inclined surface portion 53a is inclined in a direction approaching the first wall surface portion 52 from the closed end portion 55 toward the open end portion 54. The second inclined surface portion 53b is inclined in a direction away from the first wall surface portion 52 from the first inclined surface portion 53a toward the open end portion 54.

[0036] The holding member 30 of this embodiment has an inclined surface portion (second inclined surface portion 53b) that inclines in a direction away from the first wall surface portion 52, which has the advantage of making it easier to insert the protrusion portion 15 into the insertion groove 50 and easier to attach the container body 10 to the lid portion 20.

[0037] The tip of the first curved surface portion 52b (or the base end of the second curved surface portion 52c) and the tip of the first inclined surface portion 53a (or the base end of the second inclined surface portion 53b) are parallel or approximately parallel in the groove width direction (up-down direction) of the insertion groove 50. That is, the insertion groove 50 according to this embodiment has a narrow portion 50a formed with a narrow groove width in the middle of the direction in which the insertion groove 50 extends.

[0038] In this way, since the insertion groove 50 has a narrow portion 50a, the movement of the protrusion portion 15 in the insertion groove 50 is restricted when the container body 10 is held by the holding member 30, which has the advantage of preventing the container body 10 from falling off the holding member 30.

[0039] The open end 54 is located at the end of the second flat plate portion 32 opposite to the side where the first flat plate portion 31 is located in the short direction. The open end 54 is configured to allow the protrusion 15 of the container body 10 to be inserted into the insertion groove 50.

[0040] The closed end 55 is located opposite the open end 54 and is provided in a position that is parallel or approximately parallel to the insertion hole 41 of the shaft insertion portion 40 in the vertical direction. The vertical separation distance between the insertion hole 41 and the closed end 55 is approximately the same as the vertical separation distance between the protrusion 15 of the container body 10 and the shaft portion 23 of the lid portion 20 when the lid portion 20 airtightly closes the opening 13 of the container body 10.

[0041] The holding member 30 according to this embodiment is configured to be able to convert the relative rotational movement of the holding member 30 with respect to the container body 10 and the lid portion 20 into a linear movement that brings the container body 10 and the lid portion 20 closer together by sliding the protrusion 15 of the container body 10 along the insertion groove 50 (particularly, the second wall surface portion 53). In other words, the holding member 30 is configured to switch the container body 10 and the lid portion 20 from an unattached state to an attached state by sliding the protrusion 15 of the container body 10 along the insertion groove 50 (particularly, the second wall surface portion 53). In this embodiment, the holding member 30 is configured to switch the container body 10 and the lid portion 20 from a non-airtight state to an airtight state.

[0042] From this perspective, the second wall surface portion 53 has a length that allows the protrusion portion 15 of the container body 10 to be positioned on the second wall surface portion 53 when the container body 10 and the lid portion 20 switch from a non-airtight state to an airtight state.

[0043] Furthermore, the holding member 30 according to this embodiment is configured to be able to convert the relative rotational movement of the holding member 30 with respect to the container body 10 and the lid portion 20 into a linear movement that separates the container body 10 and the lid portion 20 by sliding the protrusion 15 of the container body 10 along the first wall surface portion 52. In other words, the holding member 30 is configured to switch the container body 10 and the lid portion 20 from an attached state to an detached state by sliding the protrusion 15 of the container body 10 along the first wall surface portion 52. In this embodiment, the holding member 30 is configured to switch the container body 10 and the lid portion 20 from an airtight state to a non-airtight state.

[0044] From this perspective, the first wall surface portion 52 has a length that allows the protrusion 15 of the container body 10 to be located on the first wall surface portion 52 when the container body 10 and the lid portion 20 switch from an airtight state to a non-airtight state. The first wall surface portion 52 is configured so that the degree of detachment of the container body 10 from the lid portion 20 can be adjusted by setting the angle θ between a line L1 connecting the rotation axis O of the holding member 30 in a front view of the holding member 30 and the end of the first wall surface portion 52 on the closed end 55 side and a line L2 connecting the rotation axis O of the holding member 30 and the end of the first wall surface portion 52 on the open end 54 side to any angle (see FIG. 3).

[0045] In addition, the first wall surface portion 52 is configured to be able to adjust the degree to which the container body 10 comes off from the lid portion 20 by setting the ratio of the lengths of the straight line L1, the straight line L3 connecting the rotation axis O of the holding member 30 and the position at which the container body 10 and the lid portion 20 in the first wall surface portion 52 switch from an airtight state to a non-airtight state, to any value when viewed from the front of the holding member 30 (see Figure 3).

[0046] In addition, the "end portion on the closed end side of the first wall portion" is the intersection of the first wall portion 52 and the straight line connecting the rotation axis O of the holding member 30 and the axis of the protrusion portion 15 when the protrusion portion 15 of the container body 10 is in contact with the closed end 55.

[0047] [How to attach the container body to the lid] First, the user inserts one shaft portion 23 of the lid portion 20 into the insertion hole 41 of one holding member 30, and inserts the other shaft portion 23 of the lid portion 20 into the insertion hole 41 of the other holding member 30, thereby attaching the holding members 30 to both radial ends of the lid portion 20. The user also attaches both holding members 30 holding the lid portions 20 to the respective attachment targets.

[0048] Next, the user grasps the body side wall portion 12 of the container body 10 and moves the container body 10, inserting the protrusions 15 of the container body 10 into the insertion grooves 50 from the open ends 54 of both holding members 30, and sliding them along the second wall surface portions 53 from the open ends 54 toward the closed ends 55 (see FIG. 6(a)). Thereafter, the user slides the protrusions 15 of the container body 10 along the second wall surface portions 53 until they come into contact with the closed ends 55 (see FIGS. 6(b) and 6(c)). By this operation, the rotational movement of the container body 10 and the lid portion 20 relative to the holding members 30 is converted into a linear movement that brings the container body 10 and the lid portion 20 closer to each other, and the container body 10 is attached to the lid portion 20.

[0049] At this time, the lid portion 20 closes the opening 13 of the container body 10 in an airtight state, and both holding members 30 hold the container body 10 and the lid portion 20 while maintaining the airtight state of the lid portion 20 relative to the container body 10.

[0050] [How to remove the container body from the lid] When removing the container body 10 from the lid portion 20, the user grasps the body side wall portion 12 of the container body 10 (see FIGS. 7(a) and 8(a)) held by the holding member 30, and slides the protrusion 15 of the container body 10 along the first wall surface portion 52 from the closed end 55 toward the open end 54 (see FIGS. 7(b) and 8(b)). When the protrusion 15 of the container body 10 is further slid from the state of FIGS. 7(b) and 8(b) (see FIG. 7(c)), the rotational movement of the container body 10 and the lid portion 20 relative to the holding member 30 is converted into a linear movement that separates the container body 10 and the lid portion 20, switching the container body 10 and the lid portion 20 from an airtight state to a non-airtight state, and the container body 10 is removed from the lid portion 20.

[0051] [Advantages of the container according to this embodiment] As such, the holding member 30 of this embodiment is a holding member 30 that is rotatable relative to either the container body 10 or the lid portion 20, and is used to maintain the attached state of the lid portion 20 relative to the container body 10, and is provided with an insertion groove 50 into which a protrusion 15 provided on the other of the container body 10 and the lid portion 20 can be inserted, the insertion groove 50 extending in a circumferential direction centered on the rotation axis O of the holding member 30, and is configured so that by sliding the protrusion 15 along the insertion groove 50, the relative rotational movement of the holding member 30 with respect to the container body 10 and the lid portion 20 can be converted into a linear movement that moves the container body 10 and the lid portion 20 closer to or farther apart, and the insertion groove 50 has a length that allows the protrusion 15 to be positioned within the insertion groove 50 when the container body 10 and the lid portion 20 are switched between an attached state and an detached state.

[0052] The holding member 30 having such a configuration has the advantage that the container body 10 can be attached to and detached from the lid portion 20 simply by rotating the container body 10 and the lid portion 20 relative to the holding member 30, and therefore the container body 10 can be attached and detached with little force. Furthermore, the holding member 30 according to this embodiment has the advantage that the container body 10 and the lid portion 20 gradually switch from the attached state to the detached state, and therefore when removing the container body 10 from the lid portion 20, it is possible to prevent liquid from spilling from the container body 10 due to excessive force, as would occur when removing the container body 10 with a strong force.

[0053] In the holding member 30 according to this embodiment, the insertion groove 50 has a first wall surface portion 52 extending in a circumferential direction around the rotation axis O of the holding member 30, and the holding member 30 is configured so that the relative rotational motion of the holding member 30 with respect to the container body 10 and the lid portion 20 can be converted into linear motion by sliding the protrusion 15 along the first wall surface portion 52, and the first wall surface portion 52 has a length such that the protrusion 15 is positioned on the first wall surface portion 52 when the container body 10 and the lid portion 20 are switched from the attached state to the detached state. The holding member 30 having such a configuration has the advantage that the container body 10 can be detached from the lid portion 20 simply by rotating the container body 10 and the lid portion 20 relative to the holding member 30, thereby enabling the container body 10 to be detached with little force. Furthermore, because the container body 10 and the lid 20 gradually switch from the attached state to the detached state, there is an advantage in that spillage of liquid from the container body 10 due to excessive force, which occurs when removing the container body 10 from the lid 20, can be prevented. Furthermore, by arbitrarily setting the distance from the rotation axis O of the holding member 30 to the first wall surface portion 52, the pull-out length of the container body 10 relative to the lid 20 and the above-mentioned angle θ can be freely set, which has the advantage that the force required to remove the container body 10 can be freely set, for example, if the angle θ is large, the container body 10 can be pulled out with a small force, and if the angle θ is small, the container body 10 can be pulled out with a large force.

[0054] In the holding member 30 according to this embodiment, the insertion groove 50 has an open end 54 for inserting the protrusion 15 into the insertion groove 50, and the first wall surface portion 52 has a curved portion (second curved surface portion 52c) that curves from the inside of the insertion groove 50 toward the open end 54. With the holding member 30 having such a configuration, the container body 10 and the lid portion 20 smoothly switch from the attached state to the detached state, which has the advantage that the container body 10 can be removed with a weak force and that spillage of liquid from the container body 10 can be further suppressed.

[0055] In the holding member 30 according to this embodiment, the insertion groove 50 has a second wall surface 53 that faces the first wall surface 52, and the holding member 30 is configured so that, by sliding the protrusion 15 along the second wall surface 53, the relative rotational movement of the holding member 30 with respect to the container body 10 and the lid portion 20 can be converted into linear movement that brings the container body 10 and the lid portion 20 closer together. With the holding member 30 configured in this way, the container body 10 can be attached to the lid portion 20 simply by sliding the protrusion 15 along the second wall surface 53, which has the advantage that the container body 10 can be attached with little force. Furthermore, by arbitrarily setting the curvature of the second wall surface portion 53, the resistance to the linear movement that brings the container body 10 and the lid portion 20 closer together can be freely set, which has the advantage that the force required to attach the container body 10 can be freely set, for example, by attaching the container body 10 with a large force if the curvature of the second wall surface portion 53 is small, and with a small force if the curvature of the second wall surface portion 53 is large.

[0056] [Variations] The holding member and container according to the present invention are not limited to the above-described embodiment, and various modifications can be made within the scope of the technical concept of the present invention.

[0057] In the above-described embodiment, the holding member 30 is described as being provided on the lid portion 20, but this is not limited thereto, and the holding member 30 may be provided on the container body 10. Furthermore, in the above-described embodiment, the container body 10 is described as having the protrusion 15, and the lid portion 20 is described as having the shaft portion 23, but this is not limited thereto, and the container body 10 may have the shaft portion 23, and the lid portion 20 may have the protrusion 15.

[0058] In the above embodiment, the groove width of the insertion groove 50 is not constant. However, the present invention is not limited to this, and the groove width of the insertion groove 50 may be constant.

[0059] In the above-described embodiment, the first wall portion 52 has been described as having a curved portion (second curved portion 52c) that curves in a direction that increases the groove width from the inside of the insertion groove 50 toward the open end 54, but this is not limited to this, and the first wall portion 52 may have a flat portion that slopes in a direction that increases the groove width from the inside of the insertion groove 50 toward the open end 54, or may be configured without these curved or flat portions.

[0060] In the above-described embodiment, the holding member 30 slides the protrusion 15 along the second wall surface 53 to convert the relative rotational movement of the holding member 30 with respect to the container body 10 and the lid portion 20 into a linear movement that brings the container body 10 and the lid portion 20 closer together, thereby switching the container body 10 and the lid portion 20 from a non-airtight state to an airtight state. However, this is not limited to this. For example, the holding member 30 may slide the protrusion 15 along the first wall surface 52 to convert the relative rotational movement of the holding member 30 with respect to the container body 10 and the lid portion 20 into a linear movement that brings the container body 10 and the lid portion 20 closer together, thereby switching the container body 10 and the lid portion 20 from a non-airtight state to an airtight state.
