Description

[Technical Field]

[0001] The present invention relates to an attachment to be attached to the opening of a cylindrical container, and to a cylindrical container equipped with the attachment. [Background technology]

[0002] Cylindrical containers with openings have traditionally been used to hold stick-shaped items such as fresh flowers. The sticks inserted into the cylindrical container abut against the edge of the opening. This allows the inserted items to be held in a stable state, even when a large number of sticks or thick sticks are inserted.

[0003] However, since the size of the opening of a cylindrical container is fixed, if the insert is thin or there are only a few of them, it will lean against the edge that forms the opening, making it difficult to decorate beautifully.

[0004] In order to solve such problems, various cylindrical containers have been proposed that have an opening and maintain a stable state regardless of the amount of contents inserted.

[0005] For example, Patent Document 1 describes a multipurpose vase that can hold a large number of flowers and has multiple protrusions spaced at appropriate intervals around the inner periphery, with a flower holder between the protrusions that can hold at least one flower. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-242962 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the cylindrical container described in Patent Document 1, multiple protrusions are provided at appropriate intervals around the inner circumference of the vase, so if there are a large number of rod-shaped objects to be inserted or if the rod-shaped objects are thick, the rod-shaped objects will collide with the protrusions when being inserted, making it difficult to insert them smoothly. In addition, there is a possibility that the rod-shaped body may be damaged during this process.

[0008] In addition, many users of such cylindrical containers do not have technical knowledge in the mechanical field, and it has been difficult for such users to handle structures that are difficult to operate or fragile structures.

[0009] The present invention has been made in consideration of the above-described situation, and its objective is to provide an attachment that communicates with the opening of a cylindrical container, can easily adjust the shape of its inner circumference depending on the number of items to be inserted, and is easy to operate and durable, as well as a cylindrical container equipped with the attachment. [Means for solving the problem]

[0010] The present invention, which solves the above-mentioned problems, is an attachment that can be attached to the opening of a cylindrical container, and comprises an adjustment part that can change the shape of the inner circumference, and an attachment part that is attached to the cylindrical container, wherein the adjustment part has an adjustment member that is arranged around the central axis, and an operating part that operates the adjustment member, and the adjustment member can be moved in a direction toward or away from the central axis depending on the operation of the operating part.

[0011] According to the present invention, it is possible to adjust the shape of the inner periphery depending on the amount of inserts. Even if the inserts are thin and the number is small, it is possible to hold the inserts around the central axis by communicating with the opening of the cylindrical container and adjusting the shape of the inner periphery.

[0012] In a preferred embodiment of the present invention, the adjustment member moves to a closest state in which it is closest to the central axis and a farthest state in which it is farthest from the central axis, and the adjustment member is held in a determinable position at any position between the closest state and the farthest state. By adopting such a configuration, it is possible to adjust the shape of the inner circumference to a more optimal shape depending on the amount of insert.

[0013] In a preferred embodiment of the present invention, a plurality of the adjustment members are provided, each having a first surface and a second surface, and the first surfaces are arranged surrounding the central axis. This configuration allows the insert to contact the surface, and by surrounding the central axis, prevents the insert from falling out.

[0014] In a preferred embodiment of the present invention, the first surface of one of the adjustment members abuts against the second surface of the other of the adjustment members. This configuration prevents the occurrence of gaps on the inner peripheral surface of the attachment.

[0015] In a preferred embodiment of the present invention, the first surface is provided parallel to the central axis. With this configuration, the insert is supported by a surface, preventing the insert from being scratched and enabling the insert to be held stably.

[0016] In a preferred embodiment of the present invention, the adjustment section has a groove into which a protrusion provided on the adjustment member can be inserted, the groove having a sliding groove for sliding the adjustment member and a support groove for supporting the adjustment member, the protrusion having a sliding protrusion that is inserted into the sliding groove and slides along the movement path formed by the sliding groove, and a support protrusion that is inserted into the support groove and slides along the movement path formed by the support groove, and the direction in which the sliding groove extends and the direction in which the support groove extends intersect in a planar view. By adopting such a configuration, the number of components can be minimized while achieving a change in the shape of the inner periphery, thereby increasing robustness and reducing manufacturing costs.

[0017] In a preferred embodiment of the present invention, the movement path of the slide groove is formed as a straight line in a plan view. With this configuration, the first surface of one adjustment member can slide against the second surface of the other adjustment member while being in contact with it, thereby preventing the adjustment members from tipping over.

[0018] In a preferred embodiment of the present invention, the adjustment unit has a rotating disk that rotates in response to operation of the operating unit, and the groove is provided on the rotating disk. By adopting such a configuration, it is possible to adjust the size of the inner circumference to any desired size with a single operation.

[0019] A preferred embodiment of the present invention is a cylindrical container equipped with the attachment.

[0020] In a preferred embodiment of the present invention, the mounting portion further includes a liquid holding portion below the mounting portion. With this configuration, it is possible to hold the insert in a stable state even if the insert is too short to reach the bottom of the container. [Effects of the Invention]

[0021] According to the present invention, it is possible to provide an attachment that communicates with the opening of a cylindrical container and adjusts the shape of the inner periphery depending on the amount of material to be inserted, and a cylindrical container equipped with the attachment.

DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, attachments according to a first embodiment and a second embodiment of the present invention will be described with reference to FIGS. The embodiment shown below is an example of the present invention, and the present invention is not limited to the embodiment shown below. In these drawings, the symbol X indicates an attachment according to this embodiment. In the following description, the direction of the central axis L of the attachment X is referred to as the up-down direction, and the direction perpendicular to the central axis L is referred to as the horizontal direction. The downward direction is the direction in which the user inserts the insert F into the attachment X, and the upward direction is the direction opposite to the downward direction. The dashed line in FIG. 4 represents a travel path T1, which will be described later.

[0024] <Configuration of the first embodiment> The configuration of an attachment according to a first embodiment of the present invention will be described below with reference to FIGS.

[0025] As shown in Figure 1 or Figure 2, the attachment X includes an adjustment section 1 that is provided inside and can change the shape of the inner circumference, an attachment section 2 that can be connected to a cylindrical container B, a box section 3 that is a housing that stores the adjustment section 1, and a lid section 4 that covers the adjustment section 1 from above. Here, changing the shape includes changing the size of the shape.

[0026] As shown in Figure 2 or Figure 3, the adjustment unit 1 has an adjustment member 11 that surrounds the central axis L and whose shape, including the size of the surrounding circumferential surface, can be changed according to the user's operation, an operating unit 12 that allows the user to operate the adjustment member 11, a turntable 13 that transmits the action of the operating unit 12 to the adjustment member 11, and a groove portion 14 in the turntable 13 that controls the sliding or rotating direction of the adjustment member 11.

[0027] As shown in FIG. 4, the adjustment member 11 can be moved to and held at any position between a closest state in which it is closest to the central axis L and a farthest state in which it is farthest from the central axis as shown in FIG.

[0028] As shown in FIG. 2, the adjustment member 11 has a plurality of adjustment member bodies 111, and protrusions P are provided on the adjustment member bodies 111 to protrude therefrom. The material of the adjustment member 11 is preferably plastic, but is not particularly limited as long as it has enough rigidity to prevent deformation due to sliding movement. The adjustment member main body 111 and the protrusion P may be made of different materials.

[0029] The adjustment member body 111 includes a first surface S1 that is a plane and is arranged so that at least a portion of the plane faces the central axis L, and a second surface S2 that is a plane adjacent to the first surface S1 and abuts the first surface S1 of another adjustment member body 111.

[0030] The first surface S1 is a rectangular plane and is disposed so as to be always parallel to the central axis L. The second surface S2 is a rectangular plane, shares one side with the first surface S1, and has a width smaller than that of the first surface S1, thereby making the adjustment member 11 compact. The first surface S1 may be square, or may be inclined so as to contact the second surface S2, or may be a curved surface.

[0031] The angle between the first surface S1 and the second surface S2 is an acute angle. Preferably, when the adjustment member 11 is made up of n adjustment member bodies 111, this angle is set to be approximately the same as the exterior angle of an n-gon. As a result, when the first surface S1 comes into contact with the adjacent second surface S2, the periphery surrounded by the first surface S1 forms a regular polygon, and the operational stability of the adjustment unit 1 is improved.

[0032] The adjustment member main body 111 has a generally trapezoidal shape in plan view and bottom view, and is generally a truncated quadrangular pyramid shape. In detail, the top surface (facing the turntable 13) and the bottom surface (facing the mounting portion 2) of the adjustment member main body 111 are each approximately trapezoidal in shape, with the side that forms part of the edge of the first surface S1 and the opposing side being parallel, and the length of the side that forms part of the edge of the first surface S1 is longer than the length of the opposing side. This allows the adjustment member body 111 to move while the second surface S2 remains in contact with the first surface S1 of another adjustment member body 111. Furthermore, the volume is reduced, making the adjustment member 11 lighter, and it becomes possible to move the adjustment member 11 with less force.

[0033] When the adjustment member 11 is in the closest position, as shown in Figure 4(a) or Figure 7(a), the entire surface of the second surface S2 abuts against the first surface S1, and a gap is provided between the central axis L and the first surface S1 into which an insert F (see Figure 11) can be inserted. This allows attachment X to be used as a vase for a single flower. As shown in FIG. 8(a), the inner diameter may be approximately 0 cm in the closest state.

[0034] As shown in FIG. 4(a), in a plan view in the closest state, it is preferable that the area of ​​the top surface of the adjustment member 11 exposed from the central hole of the turntable 13 described later is at least half of the central hole of the turntable 13. This prevents dust and dirt from entering the cylindrical container B when not in use.

[0035] The diameter of the inner periphery in the closest state is, for example, 3 cm.

[0036] As shown in Figure 4(c) or Figure 7(c), the adjustment member 11 in the most separated state is arranged so that the sliding protrusion P2 described later is arranged along the sliding groove G2 described later, and the second surface S2 is arranged so that at least a portion of the first surface S1 is in contact with the first surface S1 and so that substantially the entire surface of the first surface S1 faces the central axis L.

[0037] That is, the first surface S1 and the second surface S2 are provided so as to always abut at least partially, and in the adjustment member 11, adjacent adjustment member bodies 111 are arranged in an annular shape so as to always abut against each other. This allows the adjustment members 11 to support each other when sliding and rotating, preventing them from tipping over and uniquely determining the direction or angle of rotation.

[0038] The inner diameter in the most separated state is, for example, 5 cm.

[0039] The protrusion portion P includes a support protrusion P1 that is inserted into a support groove G1 described later, and a sliding protrusion P2 that is inserted into a sliding groove G2, and the support protrusion P1 and the sliding protrusion P2 are each located at a position away from the second surface S2. This makes it easier to rotate by increasing the length of the arm relative to the second friction surface S2. In this embodiment, the protrusion P is located in the vicinity of a side of the first surface S1 opposite to the shared side between the first surface S1 and the second surface S2.

[0040] The support protrusion P1 is provided on the top surface of the adjustment member body 111 (facing the turntable 13), and the sliding protrusion P2 is provided on the bottom surface of the adjustment member body 111 (facing the attachment portion 2). The support protrusion P1 and the sliding protrusion P2 are cylindrical, arranged on the same axis, and formed parallel to the central axis L. This allows the adjustment member 11 to rotate around the support protrusion P1 and the sliding protrusion P2 as an axis, and also allows the adjustment member 11 to slide around the support protrusion P1 and the sliding protrusion P2 as an axis.

[0041] In this embodiment, the adjustment member 11 includes six adjustment member bodies 111. This results in an inner peripheral surface that is approximately hexagonal in shape, making it possible to stably hold an inserted object as if it were being wrapped around a human hand.

[0042] As shown in FIG. 2, the operating unit 12 and the rotating disk 13 are a worm and a worm wheel, respectively, and a worm gear is formed by meshing them together. In addition, in the operating portion 12, rotation protrusions 121 having a diameter smaller than that of the worm extend in the axial direction from both sides. As a result, when the operating unit 12 is rotated, the turntable 13 can be rotated with a light force. Furthermore, when the rotation of the operating unit 12 is stopped, the rotation of the turntable 13 can also be stopped.

[0043] The operating unit 12 is provided across the top surface and part of the outer edge of the lid unit 4 and a cutout portion 31, which will be described later. Here, the lid unit 4 is provided with a facing rotation groove 41 into which the rotation protrusion 121 is inserted and which supports the rotation protrusion 121 so as to be rotatable in the axial direction. This allows the operating part 12 to rotate about the rotation groove 41, and allows the operating part 12 to be operated while the attachment X holds the insertion object F (see FIG. 11).

[0044] The rotating disk 13 is a worm wheel with a hole in the center. The diameter of this hole is preferably larger than the distance between the opposing first surfaces S1 of the adjustment member main body 111 when they are in the most separated state. This makes it easier to insert the insert F (see FIG. 11) into the attachment X.

[0045] The groove portion 14 has a support groove G1 that supports the adjustment member 11 and a slide groove G2 that allows the adjustment member 11 to slide.

[0046] The support grooves G1 are provided on the rotary disk 13 in a number corresponding to the number of the adjustment member bodies 111, and the support protrusions P1 are inserted into the respective grooves G1. More specifically, the support grooves G1 are arranged at equal intervals with respect to adjacent support grooves G1 so as to be point symmetric about the central axis L in plan view. This allows the adjustment member 11 to rotate and slide around the support protrusion P1 as an axis.

[0047] In this embodiment, the support groove G1 is an elongated hole that extends from near the outer periphery of the rotating disk 13 to near the inner periphery. In detail, one end of the support groove G1 is located at a position closer to the central axis than the shortest distance from the central axis L to the sliding groove G2, and the other end of the support groove G1 is located at a position farther from the central axis than the longest distance from the central axis L to the sliding groove G2. This prevents the movement of the protrusion P in the slide groove G2 from being hindered. The direction in which the support groove G1 extends may be along the radial direction of the central axis L, or may be at a certain angle relative to the radial direction, or may be a smooth curve.

[0048] Six slide grooves G2 are provided inside the bottom surface of the box part 3, and the slide protrusions P2 are inserted into each of them. In more detail, the sliding grooves G2 are linear elongated grooves that are arranged to form an approximately polygonal shape corresponding to the number of adjustment member bodies 111 in a plan view, and in this embodiment, are approximately hexagonal elongated grooves. This allows the adjustment member 11 to slide linearly along the slide protrusion P2 by rotating the operation portion 12.

[0049] In addition, when the adjustment member 11 is in the farthest state, the sliding groove G2 is arranged so as to be approximately parallel to and along the first surface S1 in a planar view, and when the adjustment member 11 is in the closest state, it is formed so as to be parallel to the first surface S1 of the adjacent adjustment member main body 111. This allows the first surface S1 and the second surface S2 to slide smoothly in the contact area.

[0050] The slide protrusion P2 is movable within the slide groove G2, and the slide grooves G2 are formed so as to intersect with each other in a plan view.

[0051] 3 or 4, the support protrusion P1 and the sliding protrusion P2 of each adjustment member 11 are inserted into the support groove G1 and the sliding groove G2, respectively. In addition, a straight line extending along the support groove G1 and a straight line extending along the sliding groove G2 are arranged to intersect in a plan view.

[0052] A movement path T1 formed by the rotation of the turntable 13 and the movement of the support protrusion P1 is substantially the same as a movement path T2 formed by the movement of the sliding protrusion P2 in a plan view.

[0053] As shown in Figure 5, the box portion 3 is a hollow truncated cone-shaped member with the top surface open over almost the entire surface and the bottom surface open near the center, and houses the adjustment member 11, the adjustment portion 1, and the turntable 13. Moreover, the diameter of the top surface side of the box part 3 is larger than the diameter of the bottom surface side. This makes it possible to hold the inserted insert F (see FIG. 11) radially in a side view. The material of the box portion 3 is preferably plastic, but is not particularly limited as long as it has rigidity.

[0054] One of the side surfaces of the box portion 3 is formed with a quadrilateral cutout portion 31 cut out from the edge on the top surface side. More specifically, the cutout portion 31 has a rectangular shape with a horizontal length longer than its vertical length. Furthermore, the horizontal length is formed to be approximately the same as or longer than the distance between opposing rotation grooves 41 so that rotation grooves 41, which will be described later, are positioned at both ends of the upper portion of the cutout portion 31 when the lid portion 4 is attached to the box portion 3. This makes it possible to attach the operating unit 12 to the side surface of the box 3. It should be noted that a plurality of cutouts 31 may be formed on the side surface of the box part 3. The shape of the cutouts 31 may be a rectangle whose vertical length is longer than its horizontal length, and is not particularly limited as long as the size is such that the operation unit 12 is exposed to an extent that it can be operated.

[0055] The lid portion 4 is a hollow disk. More specifically, the outer diameter of the lid 4 is approximately the same as the diameter of the top surface of the lid 4, and the inner diameter of the lid 4 is larger than the inner diameter of the rotating disk 13. This prevents the top surface of the rotating disk 13 from being exposed to the outside. The material of the lid portion 4 is preferably plastic, but is not particularly limited as long as it has rigidity.

[0056] The cover 4 has a rotation groove 41 into which the rotation protrusion 121 is inserted.

[0057] The rotation groove 41 is formed so as to communicate with the notch 31 and has the same width as the notch 31 . This makes it possible to operate the operating portion 12 even when the insert F (see FIG. 11) is inserted radially around the central axis L.

[0058] As shown in FIG. 5, the attachment part 2 is provided on the bottom surface of the box part 3 and has an attachment part main body 21 and a liquid holding part 22.

[0059] The attachment body 21 is an annular member having an opening that is approximately the same size as the opening of a cylindrical container B described later and through which an insert F (see FIG. 11) can be inserted. The attachment body 21 is provided with a step that allows it to come into contact with the end face of the cylindrical container B. This allows the attachment X to be attached to the cylindrical container B.

[0060] The liquid holder 22 includes a liquid holder main body 221 and a holder 222 that protrudes from the liquid holder main body 221 .

[0061] The liquid holder main body 221 has a cylindrical shape with a bottom, and is capable of storing liquid inside.

[0062] The holding portion 222 is a beam-shaped member having at least two portions protruding in a direction away from the cylindrical axis of the liquid holding portion main body 221, and each tip portion is placed on the mounting portion main body 21, thereby supporting the liquid holding portion 22 so that it is suspended. This allows the liquid holding portion 22 to support the insert F (see Figure 11) even if the length of the insert F (see Figure 11) in the direction of the central axis L is short and does not reach the bottom of the cylindrical container B.

[0063] As shown in FIG. 6, the cylindrical container B is a cylindrical container having a bottom, and supports the attachment X at a predetermined height by its own height. By obtaining the height in the direction of the central axis L with the cylindrical container B and applying restrictions in the direction perpendicular to the central axis L with the attachment X (particularly the adjustment member 11), the insert F (see Figure 11) can be supported in the desired state.

[0064] Furthermore, the cylindrical container B has a constricted portion formed by a curved surface on its side surface. This makes it possible to hold the insert F (see FIG. 11) inserted into the cylindrical container B radially in a plan view. Also, a sense of unity with the shape of the attachment X is obtained, improving the design.

[0065] There are no particular restrictions on the material of the cylindrical container B, as long as it can support an insert F (see FIG. 11) upright with a liquid inside for a long period of time. However, resin is preferred, and Tritan resin is particularly preferred. This not only prevents the cylindrical container B from yellowing, but also prevents environmental hormones from being extracted from the cylindrical container B into a liquid such as water when the cylindrical container B is filled with the liquid.

[0066] <Configuration of the second embodiment> The configuration of an attachment X according to a second embodiment of the present invention will be described below with reference to FIGS. The adjustment member 11 and the groove 14 are different from the adjustment member 11 and the groove 14 of the first embodiment, respectively. The other configurations are the same as those of the first embodiment.

[0067] As shown in FIG. 13, the adjustment member 11 has a plurality of adjustment member bodies 111, and protrusions P are provided on the adjustment member bodies 111 to protrude therefrom.

[0068] The entire edge of one adjustment member 11 is provided with rounded corners. This makes the sliding action smoother and prevents the insert F (see Figure 11) or the user's fingers (not shown) from being injured when they come into contact with the edge of the adjustment member main body 111.

[0069] The adjustment member body 111 includes a first surface S1 that is arranged so that at least a portion of the surface faces the central axis L, a second surface S2 that is adjacent to the first surface S1 and is a plane that abuts against the first surface S1 of another adjustment member body 111, and a third surface S3 that is arranged so that it faces the box portion 3 in the most separated state. The adjustment member body 111 has a generally quadrangular pyramidal shape similar to that of the first embodiment.

[0070] As shown in Figures 13 to 15, the protrusion portion P includes a support protrusion P1 inserted into the support groove G1 (see Figure 3), a sliding protrusion P2 inserted into the sliding groove G2 (see Figure 3), an adjustment protrusion P3 protruding from the second surface S2, a lower holding protrusion P4 protruding from the third surface S3, and an upper holding protrusion P5. The support protrusion P1, sliding protrusion P2, adjustment protrusion P3, lower holding protrusion P4, and upper holding protrusion P5 are preferably made of plastic, but are not particularly limited to such materials as long as they are rigid enough not to deform due to sliding movements. Also, the protrusions may be made of different materials.

[0071] The support protrusion P1 and the sliding protrusion P2 have the same configuration as the support protrusion P1 and the sliding protrusion P2 of the first embodiment, respectively.

[0072] The adjustment protrusion P3 protrudes from the back surface of the adjustment member main body 111 (facing the box portion 3 shown in Figure 6, etc.) to the second surface S2, and forms a plane parallel to the surface formed by the adjustment groove G3 of the other adjustment member main body 111 described later. This allows the adjustment protrusion P3 of one adjustment member 11 to come into contact with the adjustment groove G3 of another adjacent adjustment member 11, allowing the adjacent adjustment members 11 to support each other.

[0073] The lower holding protrusion P4 is formed so that its top surface (facing the turntable 13) coincides with the bottom surface (facing the turntable 13) of an adjustment groove G3, which will be described later. This allows the adjustment member 11 to come into contact with the adjustment protrusion P3 of the other adjustment member 11 in the most separated state, and to support the adjustment protrusion P3. Furthermore, the volume is further reduced, making the adjustment member 11 lighter, and it becomes possible to move the adjustment member 11 with less force.

[0074] The upper holding protrusion P5 is formed so that its top surface (facing the turntable 13) is substantially flush with the top surface of the adjustment member main body 111 (facing the turntable 13). This makes it possible to support the other adjustment member bodies 111 in the most separated state.

[0075] The vertical length formed by the bottom surface of the upper holding protrusion P5 (facing the mounting portion 2) and the top surface of the lower holding protrusion P4 (facing the turntable 13) is formed to be at least greater than the vertical length of the adjustment groove G3. Also, the adjustment protrusion P3 can slide from / to the most distant position.

[0076] The groove portion 14 has a support groove G1 (see FIG. 3) that supports the adjustment member 11, a slide groove G2 (see FIG. 3) that allows the adjustment member 11 to slide, and an adjustment groove G3 that holds another adjustment member 11. The support groove G1 and the slide groove G2 have the same configurations as the support groove G1 and the slide groove G2 of the first embodiment, respectively.

[0077] The adjustment groove G3 is provided on the first surface S1 and has a rectangular shape whose horizontal length is longer than its vertical length in a front view. In detail, the side of the adjustment groove G3 (in the direction toward the central axis L) is parallel to the first surface S1, and the distance of the side of the adjustment groove G3 from the plane formed by the first surface S1 is the same as the horizontal length of the adjustment protrusion P3 protruding from the second surface S2. The length in the vertical direction is large enough to allow the adjustment protrusion P3 to fit therein. This increases the surface area where the adjustment members 11 support each other when they slide, allowing for more stable operation. Furthermore, since the adjustment protrusions P3 and adjustment grooves G3 of adjacent adjustment members 11 are fitted together, the adjacent adjustment members 11 can support each other and can stably withstand loads in the direction of the central axis L.

[0078] The adjustment groove G3 has a notch formed therein so as to communicate with the top surface of the lower holding projection P4. This allows the adjustment member 11 to be spaced further away from the central axis L.

[0079] As shown in FIG. 13(a), the adjustment member 11 in the most separated state is provided so that the entire first surface S1 and the above-mentioned side surface of the adjustment groove G3 face the central axis L.

[0080] As shown in Figure 13(b), when the adjustment member 11 is in the closest position, the entire surface of the second surface S2 and the adjustment protrusion P3 abut against the first surface S1 and the adjustment groove G3, respectively, and the inner surface formed by the adjustment member 11 is adjacent to the central axis. This prevents dust and dirt from entering the cylindrical container B when not in use.

[0081] <How to use> Hereinafter, a method of using the attachment X according to the first embodiment will be described with reference to FIGS. The same applies to the method of using the attachment X according to the second embodiment.

[0082] As shown in FIG. 7, first, the user checks the circumference of the insert F that he or she wishes to insert into the cylindrical container B equipped with the attachment X.

[0083] Next, the user adjusts the size of the inner peripheral surface by rotating the operating portion 12 to fit the circumference of the insertion object F that is desired to be inserted.

[0084] At this time, as shown in Figure 4 or Figure 7, since the support protrusion P1 of the adjustment member 11 is inserted into the support groove G1, if it is desired that the inner surface formed by the adjustment member 11 be positioned further away from the central axis L, the turntable 13 rotates clockwise. On the other hand, when it is desired that the inner peripheral surface be positioned closer to the central axis L, the rotating disk 13 rotates counterclockwise. At this time, since the sliding protrusion P2 of the adjustment member 11 is inserted into the sliding groove G2, the adjustment member 11 slides along the sliding groove G2 in the direction in which the turntable 13 rotates.

[0085] In addition, at this time, the first surface S1 of one adjustment member 11 is in contact with the second surface S2 of the other adjustment member 11, so the adjustment member 11 rotates around the protrusion P as an axis.

[0086] Thereafter, when the shape of the inner circumference formed by the adjustment member 11 reaches a desired size, the user stops rotating the operation part 12 . By doing so, the rotation and sliding of each adjustment member 11 is stopped, and the shape of the inner circumference is maintained.

[0087] By the above operation, it is possible to adjust the inner circumference of the attachment X to an optimum shape according to the size of the insert F.

[0088] Next, the user inserts the insert F into the attachment X and the cylindrical container B as shown in FIG.

[0089] Thereafter, when further adjusting the shape of the inner circumference to an optimum shape, the adjusting unit 1 is operated in the same manner.

[0090] By doing so, it becomes possible to further adjust the shape of the inner circumference to an optimum one.

[0091] 11, when the number of inserts F desired to be inserted is small and the diameter is small, the liquid retaining portion 22 (not shown) is attached to the attachment portion 2 first.

[0092] Next, the insert F is inserted so as to penetrate the liquid holder main body 221 .

[0093] Next, the operating portion 12 is operated to appropriately adjust the shape of the inner circumference.

[0094] By doing so, it is possible to stand a small number of inserts F having a small diameter.

[0095] <Effects> According to each of the above-described embodiments, the adjustment member 11 can be moved in a direction toward or away from the central axis L in response to operation of the operating portion 12, thereby making it possible to change the shape of the inner circumference in accordance with the size of the circumference of the insert F.

[0096] In addition, a plurality of adjustment members 11 are provided, and each first surface S1 is arranged to surround the central axis L, which allows the first surface S1 to abut against the insert F. Also, by surrounding the central axis L, the insert F is prevented from falling off.

[0097] Furthermore, each first surface S1 abuts against the second surface S2 of another adjustment member 11, thereby preventing the generation of a gap on the inner circumferential surface formed by the adjustment member body 111.

[0098] Furthermore, since each first surface S1 is provided parallel to the central axis L, the insert F is supported by the first surface S1, preventing the insert F from being scratched. Also, the insert F can be stably held.

[0099] The adjustment unit 1 also has a support protrusion P1 that is inserted into the support groove G1 and slides along the movement path T1 formed by the support groove G1, and a sliding protrusion P2 that is inserted into the sliding groove G2 and slides along the movement path T2 formed by the sliding groove G2. In addition, the movement path T1 and the movement path T2 intersect in a plan view. This allows for the change in the inner periphery shape while minimizing the number of components, improving robustness and reducing manufacturing costs.

[0100] Furthermore, since the movement path T1 is configured as a straight line when viewed in a plane, when adjusting the size of the inner circumference, the first surface S1 of one adjustment member 11 can be kept in contact with the second surface S2 of the other adjustment member 11, preventing the adjustment member 11 from tipping over.

[0101] In addition, the adjustment unit 1 has a turntable 13 that rotates in response to the operation of the operating unit 12, and the groove portion 14 is provided on the turntable 13, making it possible to adjust the inner circumference to the optimal shape with a single operation.

[0102] Furthermore, the mounting portion 2 has a liquid holding portion 22 at its bottom, which allows the inserted object to be held in a stable state even if the inserted object is too short to reach the bottom of the container.

[0103] <Example of change> The shapes and dimensions of the components shown in the above-described embodiments are merely examples and can be modified in various ways based on design requirements, etc.

[0104] For example, in the first embodiment, in the closest state in which the adjustment member 11 is closest to the central axis L as shown in Figure 8(c), the distance between the central axis L and the inner surface formed by the adjustment member 11 may be approximately 0 cm. This prevents dust and dirt from entering the cylindrical container B when not in use.

[0105] For example, in the second embodiment, when the adjustment member 11 is in the closest state as shown in FIG. 4(c), in which the adjustment member 11 is closest to the central axis L, a gap into which an insert F (see FIG. 11) can be inserted may be provided between the central axis L and the inner circumferential surface formed by the adjustment member 11.

[0106] For example, in each embodiment, the operating unit 12 may have a knob in addition to the worm wheel. This knob is a member having a grip portion, and is engaged with the worm wheel or is provided integrally with the worm wheel. This allows the operating portion to be gripped, improving operability. The gripping portion may also be made of resin. This allows the user to grasp and operate the operating unit even when their hands are wet.

[0107] The attachment X and the container B equipped with it can be suitably used as an attachment for an aroma reed diffuser in addition to being used as a flower vase. [Explanation of symbols]
