(Embodiment 1)
[Configuration of Cleaning Tool 1]
FIG. 1 is a diagram illustrating a configuration of a cleaning tool 1 according to Embodiment 1 of the present invention. FIG. 1 (a) is a schematic plan view of the cleaning tool 1, FIG. 1 (b) is a schematic cross-sectional view taken along the line AA of FIG. 1 (a), and FIG. FIG. 1A is a schematic sectional view taken along line BB in FIG. 1A, and FIG. 1D is a schematic sectional view taken along line CC in FIG. Hereinafter, the configuration of the cleaning tool 1 will be described with reference to FIG. The cleaning tool 1 mainly includes a cleaning body 2 and a handle 6. The cleaning body 2 includes a base sheet 4 and a fiber bundle 7.

The base material sheet 4 is joined to the fiber bundle 7 and the fiber bundle 7 is fixed. The base sheet 4 forms a flat cylindrical portion (hereinafter referred to as “flat cylindrical portion”) into which the handle portion 6 can be inserted and removed. The base sheet 4 is a rectangular nonwoven fabric, more preferably a strip-shaped nonwoven fabric. Examples of the nonwoven fabric material include spunbond nonwoven fabric, thermal bond nonwoven fabric, spunlace nonwoven fabric, dry nonwoven fabric, wet nonwoven fabric, melt blown nonwoven fabric, chemical bond nonwoven fabric, needle punch nonwoven fabric, stitch bond nonwoven fabric, steam jet nonwoven fabric, and the like.

The fiber bundle 7 comes into contact with the surface to be cleaned and entangles dust. The fiber bundle 7 is an aggregate of a large number of fibers 3 (tow fibers) having a predetermined length, and the flow direction of the fibers 3 is aligned. The fiber bundle 7 as a whole has a width longer than the length (width) of the base sheet 4 in the short direction and a length in the longitudinal direction shorter than the length of the base sheet 4 in the longitudinal direction. The width of the fiber bundle 7 corresponds to the length of the fiber 3. The fiber bundle 7 has a linear joint portion (hereinafter referred to as “linear joint portion”) that joins the fibers 3 to each other at a position that passes through the center of the fiber bundle 7 in the width direction and that crosses the fiber flow direction. 5) is formed. In addition, it is preferable that the linear junction part 5 is formed in the direction orthogonal to the direction through which the fiber 3 flows.

The fibers 3 constituting the fiber bundle 7 include, for example, natural fibers such as cotton and wool, synthetic fibers such as polyethylene, polypropylene, polyethylene terephthalate, nylon, and polyacryl, core-sheath fibers, sea-island fibers, and side-by-side fibers. A composite fiber or the like is used. In addition, when the fibers are partially bonded by heat fusion, a core-sheath type composite fiber having a core made of polypropylene and a sheath made of polyethylene is preferable. This is because polyethylene constituting the sheath has excellent heat-fusibility and polypropylene constituting the core has high rigidity.

The thickness of the fiber 3 constituting the fiber bundle 7 is preferably about 0.01 mm to 0.3 mm in diameter. By setting it as such a thickness, dust can be wound up moderately. On the other hand, the length of the fibers 3 constituting the fiber bundle 7 is preferably in the range of about 3 cm to 15 cm. Further, it is more preferable that ten arbitrary fibers 3 are selected and the average fiber length is longer than the width of the base sheet 4 by about 3 cm to 6 cm. The fiber bundle 7 may be composed of fibers having the same material, thickness, color, etc., or at least one of these may be composed of different fibers.

The linear joint 5 in the fiber bundle 7 is formed by a method such as thermal fusion, ultrasonic bonding, bonding with an adhesive, or stitching. Of these, ultrasonic bonding is preferred. In the case of using an adhesive, a two-part curable adhesive, a thermoplastic resin adhesive, an elastomer adhesive, a thermosetting resin adhesive, an instantaneous adhesive, a hot melt adhesive, or the like is used. be able to. However, a hot melt type adhesive is preferable from the viewpoint that a rapid bonding operation by heating and cooling is possible. In addition, a solution type or emulsion type thermoplastic resin-based adhesive or elastomer-based adhesive is preferable from the viewpoint of good fiber permeability and a deep adhesive layer.

The base sheet 4 and the fiber bundle 7 are joined in a state where the center line passing through the center in the width direction of the base sheet 4 in the longitudinal direction and the linear joint portion 5 of the fiber bundle 7 are overlapped. Specifically, the base material sheet 4 and the fiber bundle 7 are separated from each other by a first predetermined dimension (L1) from the linear joint portion 5 toward both ends of the fiber 3 (both side edges of the base material sheet 4). Joined in a dotted manner at a plurality of locations on the straight line. A joined portion formed by this joining is referred to as a first point-like joined portion 8 (corresponding to another joined portion).

Further, the fiber bundle 7 is dotted at a plurality of points on a straight line separated from the linear joint portion 5 by the second predetermined dimension (L2) respectively toward both ends of the fiber 3 (both side edges of the base sheet 4). Are joined together. A joined portion formed by this joining is referred to as a second point-like joined portion 9 (corresponding to a joined portion).

Here, the first predetermined dimension (L1) is a dimension smaller than half the width of the base sheet 4. The second predetermined dimension (L2) is larger than the first predetermined dimension (L1). That is, the second point joint 9 is located closer to the both ends of the fiber 3 than the first point joint 8. In other words, the second dotted joint 9 is located in the vicinity of the side edge of the base sheet 4. The vicinity of the side edge portion of the base material sheet 4 is a region included from the side edge of the base material sheet 4 to the inside and outside of the base sheet 4 by 1/5 to 1/3 width, for example. Specifically, for example, the second dotted joint 9 may be on the base sheet 4, may straddle the side edges of the base sheet 4, and It may be located outside. Any or all of these may be combined. In addition, each of the second point-like joints 9 is located between adjacent first point-like joints 8 in the longitudinal direction of the base sheet 4.

Thereby, since the 2nd dotted joint part 9 is located in the side edge part vicinity of the base material sheet 4, when the fiber 3 opens from the position of the 2nd dotted joint part 9 (opening), the opened fiber 3 covers the side edge of the base material sheet 4, and the division of the fibers 3 is less likely to occur. Therefore, it is possible to prevent the dust capturing performance from being lowered at the division of the fibers 3. Moreover, since it becomes difficult to see with the fiber 3 which the base material sheet 4 opened, the appearance of the cleaning body 2 can be kept favorable. Further, even when the cleaning body 2 is wiped strongly, the fiber bundle 7 is bonded in the vicinity of the side edge of the base sheet 4, so that the fibers 3 are separated at the side edge of the base sheet 4. Can be prevented.

In addition, what is necessary is just to measure the position of the 1st dotted joint part 8 and the 2nd dotted joint part 9 on the basis of the center of a dotted joint part. In addition, the first point-like joint 8 and the second point-like joint 9 are formed by a method such as thermal fusion, ultrasonic bonding, bonding with an adhesive, or stitching, but are formed by ultrasonic bonding. Is preferred.

Note that a chemical may be added to the fiber bundle 7. As a chemical | medical agent, what contains at least 1 or more among mineral oil, synthetic oil, silicone oil, surfactant, and a synthetic resin is mentioned. Among such drugs, it is particularly preferable to use liquid paraffin. Thereby, since a chemical | medical agent adsorb | sucks dust, the capture | acquisition performance of dust can be improved more.

The handle portion 6 has a rod-like shape and is inserted into the flat cylindrical portion of the cleaning body 2 to support the cleaning body 2. The handle portion 6 is inserted into the flat cylindrical portion so that the tip does not reach the bent portions of the base sheet 4 and the fiber bundle 7. Thereby, since a play can be performed at the bent portion of the fiber bundle 7 corresponding to the tip of the cleaning body 2, safety can be improved and follow-up ability to follow the unevenness of the surface to be cleaned can be improved. .

Also, the handle 6 has a gripping part that protrudes from the flat cylindrical part when inserted into the flat cylindrical part of the cleaning body 2. The handle 6 is arranged such that its longitudinal direction crosses the flow direction of the fibers 3. At this time, it is preferable that the handle portion 6 is arranged along the linear joint portion 5 in the longitudinal direction.

The shape of the handle portion 6 is a columnar shape (or a cylindrical shape) in FIG. However, the handle 6 is not limited to a cylindrical shape, and may be a polygonal column such as a triangular column or a quadrangular column. Examples of the material of the handle 6 include plastic, polypropylene (PP), polyethylene (PE), paper, and rubber. However, the handle 6 is preferably disposable. For this reason, when discarding the handle | stem | pattern part 6 by incineration etc., it is desired that it is the material which suppressed the load given to an environment. In addition, the material is not particularly limited as long as the material can support the cleaning body 2. Further, the handle 6 may be solid or hollow, but is preferably formed hollow in terms of weight reduction. It is preferable that both end surfaces of the handle 6 are open.

Incidentally, the handle 6 preferably has a different color from the fibers 3 of the fiber bundle 7. Since the color of the handle 6 and the color of the fiber 3 are different, it becomes easy to visually recognize the position of the handle 6. In addition, it will have an aesthetic appearance, and the user will be able to work on cleaning with a pleasant feeling.

[Method for Manufacturing Cleaning Body 2]
Next, a method for manufacturing the cleaning body 2 described above will be described with reference to FIGS. 2 (a) to 2 (c).

A large number of long fibers 3 are arranged in parallel so that the longitudinal directions of the fibers 3 are aligned to form a sheet, thereby obtaining a fiber assembly sheet (hereinafter referred to as “web sheet”) 10 (fiber arrangement step).

Next, the fibers 3 are linearly joined to each other in a direction crossing the flow direction of the fibers 3 constituting the web sheet 10 (for example, a direction orthogonal to the longitudinal direction of the fibers 3), whereby the web sheet 10 In this way, the linear joint 5 is formed. The linear joining parts 5 are formed at predetermined intervals in the flow direction of the fibers 3 (FIG. 2A) (linear joining part forming step).

Following the linear joint forming step, the web sheet 10 is cut in a direction crossing the flow direction of the fibers 3 at a position (cut line 13) that is equidistant from the adjacent linear joint 5 (web sheet cutting step). ). A fiber bundle 7 as shown in FIG. 2B is obtained by the web sheet cutting step.

Subsequent to the web sheet cutting step, the base sheet 4 cut into a strip shape having a predetermined size and the fiber bundle 7 obtained by cutting in the web sheet cutting step are overlapped. At this time, the center line perpendicular to the width direction at the center in the width direction of the base sheet 4 and the linear joint portion 5 of the fiber bundle 7 are overlapped. The base material sheet 4 and the fiber bundle 7 stacked in this way are folded in the direction of the arrow P at the bending portion R with the fiber bundle 7 facing outward (the base material sheet 4 facing inside) (bending step). .

2B, the position of the bending portion R when the base sheet 4 and the fiber bundle 7 are bent is a position that passes through the center of the fiber bundle 7 in the longitudinal direction. For this reason, when the base sheet 4 and the fiber bundle 7 are bent at the bending portion R, the base sheet 4 and the fiber bundle 7 are half-folded, and both ends of the base sheet 4 and both ends of the fiber bundle 7 are respectively opposite. Note that the position of the bending portion R is not limited to this example, and may be a position shifted from the longitudinal center of the fiber bundle 7 in the flow direction of the fibers 3.

Following the bending process, as shown in FIG. 2 (c), the folded base sheet 4 and fiber bundle 7 are formed from the linear joint portion 5 to both ends of the fibers 3 (both edges of the base sheet 4). Toward, a plurality of points on a straight line separated by the first predetermined dimension (L1) are joined in a dot shape (joining by the first point-like joint 8). Further, the bent base sheet 4 and the fiber bundle 7 are linearly separated from the linear joint 5 toward the both side edges by a second predetermined dimension (L2) larger than the first predetermined dimension (L1). Are joined to each other at a plurality of points (joining by the second spot joining portion 9) (spot joining process).

At this time, since the vicinity of both side edges of the folded base material sheets 4 is partially joined by the first point joint 8, the joint of the base material sheet 4 and the fiber bundle 7 was folded and faced each other. Bonding of the base material sheets 4 can be performed simultaneously. Moreover, the base material sheet 4 forms a flat cylindrical part by this joining. In addition, although it is preferable that the joining by the 1st dotted joint part 8 and the joining by the 2nd dotted joint part 9 are performed simultaneously, it does not necessarily need to be performed simultaneously.

続き Following the dotted joining step, the compressed air is blown onto the fiber bundle 7 joined to the base sheet 4, whereby the fibers 3 of the fiber bundle 7 are opened (opening step). Thereby, as shown in FIG. 3, since the fiber bundle 7 can form a cylindrical outer shape, a wide range of dust can be entangled with one wiping or a small number of steps, and cleaning can be performed efficiently. Moreover, even if it is a complicated to-be-cleaned surface, since the fiber bundle 7 opened in the columnar shape can entangle dust in the circumferential direction, cleaning becomes easy.

In addition, the cleaning tool 1 is manufactured by inserting the handle 6 into the flat cylindrical portion of the cleaning body 2 manufactured as described above.

Thus, according to Embodiment 1, the fiber bundle 7 and the base sheet 4 are overlapped, and the fiber bundle 7 and the base sheet 4 are joined in the vicinity of the side edge of the base sheet 4 or the fibers 3 are joined together and the fiber 3 is opened. Thereby, even in the vicinity of the side edge of the base sheet 4, the fiber 3 is less likely to be divided by the opened fiber 3, preventing a decrease in dust capturing performance, and maintaining a good appearance. it can.

In the present embodiment, the base sheet 4 and the fiber bundle 7 are overlapped and bent, and then the second point joint 9 is joined. However, the present invention is not limited to this. For example, after the base sheet 4 and the fiber bundle 7 are overlapped and before they are bent, they may be joined by the second point joint 9 in the vicinity of the side edge of the base sheet 4.

Further, in the present embodiment, it has been described that the handle portion 6 is detachably attached to the cleaning body 2, but the present invention is not limited to this, for example, even if the handle portion 6 is fixed to the base sheet 4. Good. Examples of the fixing method at this time include thermal fusion, ultrasonic bonding, and bonding with an adhesive.

(Embodiment 2)
4 (a) to 4 (c) are diagrams for explaining a cleaning body manufacturing method according to Embodiment 2 of the present invention. Hereinafter, the cleaning body manufacturing method will be described with reference to FIGS. 4 (a) to 4 (c).

As shown to Fig.4 (a), a fiber assembly sheet | seat (web sheet | seat 10) is arrange | positioned in parallel so that many elongate fibers 3 align the longitudinal direction of the fibers 3, and become a sheet form. Obtained (fiber arrangement step).

Subsequent to the fiber arranging step, the web sheet 10 is cut in a direction crossing the flow direction of the fibers 3 at a predetermined position (web sheet cutting step). A fiber bundle 7 as shown in FIG. 4B is obtained by the web sheet cutting step.

Subsequent to the web sheet cutting step, the base sheet 4 cut into a strip shape having a predetermined size and the fiber bundle 7 obtained by cutting in the web sheet cutting step are overlapped. At this time, the center line passing through the center of the base sheet 4 in the width direction and the center line passing through the center of the fiber bundle 7 in the width direction are overlapped. The base sheet 4 and the fiber bundle 7 stacked in this way are folded in the direction of the arrow P at the bending portion R with the fiber bundle 7 facing outside (the base sheet 4 facing inside) (bending step). ).

Following the bending step, as shown in FIG. 4C, the folded base sheet 4 and fiber bundle 7 are joined linearly at the center in the width direction (joining by the linear joining portion 5). Further, the fiber bundle 7 is joined in a dotted manner at a plurality of points on a straight line separated from each other by a first predetermined dimension (L1) from the center in the width direction toward both ends of the fiber 3 (both edges of the base sheet 4). (Joining by the first point joint 8). Further, straight lines separated from the center in the width direction of the fiber bundle 7 by a second predetermined dimension (L2) that is larger than the first predetermined dimension (L1), respectively, toward both ends of the fiber 3 (both edges of the base sheet 4). It joins in the shape of a point in a plurality of upper places (joining by the 2nd point joint 9) (joining process). In addition, it is preferable that the joining by the linear joining part 5, the joining by the 1st point joining part 8, and the joining by the 2nd point joining part 9 are performed simultaneously. Thereby, several joining will be performed at once and the number of processes can be reduced. However, the plurality of joints do not necessarily have to be performed simultaneously.

After the joining step, the compressed air is blown onto the fiber bundle 7 joined to the base sheet 4, whereby the fibers 3 of the fiber bundle 7 are opened (opening step).

(Embodiment 3)
FIG. 5 is a diagram showing variations of the handle according to the third embodiment of the present invention. Here, the handle is cylindrical, hollow, transparent, and open at both ends.

FIG. 5A shows a state where one joint portion 14 connects the first handle portion 15 and the second handle portion 16. The joint part 14 has a substantially cylindrical shape. The outer diameter of one end side of the joint part 14 is substantially the same as or slightly smaller than the inner diameter of the opening of the first handle part 15. Moreover, the outer diameter of the other end side of the joint part 14 is substantially the same or slightly smaller than the inner diameter of the opening of the second handle part 16. Accordingly, one end of the joint portion 14 is fitted into the opening portion of the first handle portion 15, and the other end of the joint portion 14 is fitted into the opening portion of the second handle portion 16. As a result, the first handle portion 15 and the second handle portion 16 can be connected via the joint portion 14, and the handle portion can be lengthened. For this reason, the cleaning body 2 can be delivered to the place where it is difficult for the user to reach. Moreover, if the 1st pattern part 15 and the 2nd pattern part 16 are divided | segmented and packed, a packaged item can be made compact. Note that the joint portion 14 may be hollow or solid. Further, the joint portion 14 may have a tapered shape in which the outer diameter gradually decreases toward the both end portions with respect to the outer diameter near the center. In this case, the joint portion 14 can be easily fitted into the openings of the first handle portion 15 and the second handle portion 16.

FIG. 5B shows a state in which the pair of joints connect the first handle portion 15 and the second handle portion 16. The pair of joints includes a first joint portion 17a and a second joint portion 17b and is solid. The first joint part 17a and the second joint part 17b have a substantially cylindrical shape.

The outer diameter on the one end side of the first joint portion 17a is substantially the same as or slightly smaller than the inner diameter of the opening of the first handle portion 15. Moreover, the recessed part is formed in the bottom face of the other end of the 1st joint part 17a.

On the other hand, the outer diameter on the other end side of the second joint portion 17b is substantially the same as or slightly smaller than the inner diameter of the opening of the second handle portion 16. Moreover, the convex part is formed in the bottom face of the other end of the 2nd joint part 17b.

The convex part of the second joint part 17b is fitted and engaged with the concave part of the first joint part 17a, and the first handle part 15 and the second handle part 16 are joined. Thereby, the effect similar to the joint part 14 shown to Fig.5 (a) can be acquired.

FIG. 5C shows a state in which the pair of joints connected by the hinge 18 connects the first handle portion 15 and the second handle portion 16. A pair of joints are connected by the hinge 18, and the first joint portion 17 a and the second joint portion 17 b relatively rotate around the hinge 18. Thereby, in addition to the effect similar to the joint part 14 shown to Fig.5 (a), the loss of one joint part can be prevented.

FIG. 5D shows a state in which the opening of the first handle 15 is sealed without using the second handle 16. The end cap 19 has a substantially cylindrical shape. The outer diameter of one end side of the end cap 19 is substantially the same as or slightly smaller than the inner diameter of the opening of the first handle 15. As a result, the end cap 19 is fitted into the opening of the first handle 15. The end cap 19 is provided with a through hole (hook hole) 20. Thereby, for example, the cleaning tool 1 can be hung on a wall or a pillar by passing a hook provided on a wall or a pillar through the through hole 20. Note that the end cap 19 does not necessarily have to be provided with the through hole 20 and may simply have a function of sealing the opening of the first handle 15.

FIG. 5 (e) shows a state in which decoration or the like is applied to the inside of the first handle 15 in FIG. 5 (d). Beads, marbles, deodorants, fragrances, and the like may be accommodated inside the hollow and transparent (including translucent) first handle 15. In the case of storing the deodorant and the fragrance, a member 29 such as a net or a filter is provided at at least one end of the first handle 15 so that the stored contents do not pop out and the air passes. Is provided.

In addition, paper, a seal, a film, a plate, or the like on which characters, symbols, figures, patterns, patterns, and the like are described may be accommodated inside the hollow and transparent (including translucent) handle.

In addition to sealing with the joint part and end cap described above, sealing by sticking a seal, sealing by melting both ends of the pattern part with heat is possible as a sealing method for the opening parts at both ends of the handle part that has been decorated. There are various methods such as stopping and sealing by pushing the padding.

(Embodiment 4)
FIG. 6 is a view showing a cleaning tool according to Embodiment 4 of the present invention. FIG. 6 differs from FIG. 3 in that the handle 6 is changed to the handle 21.

The handle portion 21 has a stretchable straw structure. Specifically, the handle portion 21 includes a first handle portion 22 and a second handle portion 23, and the handle portion 21 is configured such that the second handle portion 23 can slide in the first handle portion 22. It has elasticity as a whole. The handle 21 can change between a contracted state shown in FIG. 6A and an extended state shown in FIG. 6B. Thereby, at the time of sale or at the time of storage, the handle 21 can be contracted to be compact, while at the time of use, the handle 21 can be extended to improve the operability of the cleaning tool.

FIG. 7A is a plan view of the first handle 22, and FIG. 7B is a plan view of the second handle 23. The first handle portion 22 has a hollow structure with both ends opened, and the opening inner diameter a at the end is slightly smaller than the central inner diameter b. The second handle 23 has a hollow structure with both ends open, and the outer diameter d at one end is slightly larger than the outer diameter c at the center. At this time, the relationship b> d ≧ a is satisfied. Since it has such a configuration, by inserting the second handle 23 into the first handle 22, one end of the second handle 23 slides from one end to the other end in the first handle 22. It becomes possible, and the one end part of the 2nd handle part 23 can be latched by the both ends of the 1st handle part 22, respectively. For this reason, the second handle part 23 once inserted into the first handle part 22 does not easily fall off from the first handle part 22.

The shapes of the first handle 22 and the second handle 23 are cylindrical. However, these are not limited to a cylindrical shape, and may be a cylindrical shape whose cross-sectional shape is a polygon such as a triangle or a quadrangle. Examples of the material of the first handle 22 and the second handle 23 include plastic, polypropylene (PP), polyethylene (PE), paper, and rubber. However, the first handle 22 and the second handle 23 are preferably disposable. For this reason, when discarding the 1st pattern part 22 and the 2nd pattern part 23 by incineration etc., it is desirable that it is the material which suppressed the load given to an environment. In addition, the material is not particularly limited as long as the material can support the cleaning body 2. The first handle 22 and the second handle 23 are preferably open at both end faces.

The first handle portion 22 may be processed into a bellows shape as shown in FIG. Thereby, as shown in FIG. 9, the cleaning body 2 can be bent, and the edge of the high place can be easily cleaned by the bent tip portion, or the user can clean the low place such as the floor surface. Can be performed in a relatively easy posture. Here, the first handle portion 22 is subjected to bellows-like processing, but the second handle portion 23 may be subjected to bellows-like processing.

(Embodiment 5)
Fig.10 (a) and FIG.10 (b) are figures which show the cleaning tool which concerns on Embodiment 5 of this invention. 10 (a) and 10 (b) are different from FIGS. 6 (a) and 6 (b) in that the handle portion 21 is changed to the handle portion 24. FIG. Specifically, in the handle portion 21, the side that supports the cleaning body 2 (first handle portion 22) is larger in diameter than the grip portion side (second handle portion 23), whereas in the handle portion 24. The difference is that the side that supports the cleaning body 2 (the first handle portion 25) has a smaller diameter than the grip portion side (the second handle portion 26 and the third handle portion 27). Further, the pattern portion 21 expands and contracts only in one stage, whereas the pattern portion 24 expands and contracts in two stages. However, the expansion / contraction of the handle is not limited to two-stage expansion / contraction, but may be one-stage expansion / contraction, or three-stage expansion / contraction.

The handle portion 24 has an expandable / contractible straw structure. Specifically, the handle portion 24 includes a first handle portion 25, a second handle portion 26, and a third handle portion 27, and the second handle portion 26 is slidable with respect to the outer periphery of the first handle portion 25. In addition, the third handle portion 27 is slidable with respect to the outer periphery of the second handle portion 26. Thereby, the handle portion 24 as a whole has elasticity. That is, the handle 24 can change between the contracted state shown in FIG. 10A and the extended state shown in FIG. Moreover, since the gripping part is thicker than the side that supports the cleaning part 2, it is easy to grip and the cleaning part 2 can be operated stably.

11A is a plan view of the first handle 25, FIG. 11B is a plan view of the second handle 26, and FIG. 11C is a plan of the third handle 27. FIG. FIG.

The first handle portion 25 has a hollow structure with both ends opened, and as shown in FIG. 11A, the outer diameter e of one end is slightly smaller than the outer diameter f of the other end. Further, as shown in FIG. 11B, the second handle portion 26 has a hollow structure with both ends opened, and the opening inner diameter g at one end is slightly smaller than the central inner diameter h. The outer diameter j at the end is slightly larger than the outer diameter i at the one end. At this time, there is a relationship of h> f ≧ g. Since it has such a configuration, by inserting the first handle portion 25 into the second handle portion 26, the second handle portion 26 has one end portion with respect to the outer periphery on the other end side of the first handle portion 25. The other end portion of the second handle portion 26 is locked at the other end portion of the first handle portion 25. For this reason, once the first handle 25 is inserted through the second handle 26, the second handle 26 does not easily fall off the first handle 25.

Further, as shown in FIG. 11C, the third handle 27 has a hollow structure with both ends opened, and the opening inner diameter k at the end is slightly smaller than the central inner diameter l. At this time, there is a relationship of l> j ≧ k. Since it has such a configuration, by inserting the second handle 26 into the third handle 27, one end of the third handle 27 with respect to the outer periphery on the other end side of the second handle 26. The other end portion of the third handle portion 27 is locked with the other end portion of the second handle portion 26. For this reason, once the second handle 26 is inserted through the third handle 27, the third handle 27 does not easily fall off the second handle 26.

In addition, since the shape and material of the handle part 24 are the same as those of the handle part 21 described in the fourth embodiment, a detailed description thereof will be omitted.

Also, the handle 24 is formed by extrusion and pressing. Compared with injection molding that requires a mold, this does not require a mold, the length of the handle 24 can be freely adjusted, and the cost can be reduced.

In Embodiment 4 and Embodiment 5 described above, the handle having a straw structure is hollow and transparent (including translucent), and beads, marbles, deodorants, fragrances, etc. are accommodated therein. Good. In addition, paper, a seal, a film, a plate, or the like on which characters, symbols, figures, patterns, patterns, and the like are described may be accommodated inside a hollow and transparent (including translucent) handle.

The embodiment has been described above.
