Description

SANITARY MATERIAL AND WINDING TAPE

Technical Field

One aspect of the present disclosure relates to a sanitary material and a winding tape.

Background

JP2015-134018 A describes a diaper as a disposable pants-type wearing article. The diaper includes an annular elastic waist panel extending in the waist circumferential direction and an absorbent chassis joined to the elastic waist joining panel. The elastic waist panel includes a front waist panel located in a front waist region and a rear waist panel located in a rear waist region. A tape fastener is attached to the rear waist panel.

Each of a pair of tape fasteners fixed to the outer surface of the rear waist region includes a base sheet that is a sheet of tape folded in a cross-sectional Z-shape. The tape fastener includes a proximal part located at one end of the tape fastener and fixed to the outer surface of the rear waist region unreleasably by interposing a joining region, a first distal part folded from the proximal part by interposing a first folding part and overlapping the proximal part, and a second distal part folded from the first distal part by interposing a second folding part and overlapping the first distal part.

A pinching part extends from the second distal part by interposing the aforementioned first folding part, and the pinching part and the second distal part, the first distal part, and the proximal part are stacked in a Z-shape. A latching region (fastening region) formed of a pressure-sensitive adhesive is disposed between the first and second distal parts. When the tape fastener is used, the pinching part is pinched with fingers to release the latching region, and the second distal part is separated from the first distal part. Then, the second distal part and the first distal part, which have been formed in a Z-shape, are opened and the latching region joined to the second distal part is attached to the front waist region, whereby the rear waist region is joined to the front waist region and the diaper can be rolled.

Summary

Technical Problem

When the second distal part of the aforementioned tape fastener stacked in a Z-shape is separated from the first distal part, the latching region formed of the pressure-sensitive adhesive is exposed. Therefore, when the second distal part is separated from the first distal part by pinching the pinching part, the latching region may adhere to a finger or the like, and may be difficult to use. Further, in the aforementioned tape fastener, the proximal part is fixed to the outer surface of the rear waist region unreleasably, and the first distal part, the second distal part, and the pinching part are opened from the proximal part as a starting point. Therefore, since the position of the proximal part is fixed, depending on the length of the tape fastener, it may be difficult to attach the latching region to the front waist region, and there is room for

improvement in the operability of the attaching operation.

Further, in the aforementioned Z-shaped tape fastener, two steps of operation are required, i.e., an operation for separating the pinching part and the second distal part from the first distal part and an operation for separating the first distal part from the proximal part, and in this point, there is room for improvement in the operability. Also, with this type of tape, it may be desirable to move the place where the tape is attached depending on the condition of the sanitary material or the winding manner. However, in the aforementioned tape fastener, since the proximal part of one end is fixed so as not to be releasable, the place where the tape is to be attached can hardly be moved. As described above, in the tape fasteners, there is room for improvement in the operability of the winding operation of the sanitary materials.

Solution to Problem

A sanitary material according to one aspect of the present disclosure includes a non- woven fabric, and a winding tape configured to be attached to the non-woven fabric, where the winding tape includes a fixed part fixed to the non-woven fabric, a stretchable part configured to stretch with the fixed part as a starting point, and a locking part provided closer to each of both ends of the stretchable part in the longitudinal direction of the winding tape and configured to be attachable to and detachable from the non-woven fabric.

In the sanitary material according to one aspect above, a stretchable material stretches with a fixed part as a starting point, and a locking part configured to be attachable to and detachable from the non-woven fabric is provided closer to each of both ends of the stretchable material. Therefore, since the stretchable material stretches with the fixed part as a starting point, the position of the winding tape can be extended to a desired position of the non-woven fabric.

As a result, the sanitary material can be wound in a desired winding manner. That is, since the direction in which the winding tape extends can be changed by changing the direction in which the stretchable part extends from the fixed part, the sanitary material can be wound in various winding manners. Therefore, the operability of the winding operation of the sanitary material can be improved. Further, since the locking part is provided closer to each of both ends of the stretchable part, the stretchable part can be extended to an arbitrary position and the locking part can be locked to an arbitrary position of the non-woven fabric. Therefore, by changing the length and the direction of the winding tape when extending the stretchable part, the locking position and the direction of the locking part in the non-woven fabric can be appropriately changed. That is, the locking part can be locked at an arbitrary position and an arbitrary direction of the non- woven fabric. Therefore, the operability of winding operation of the winding tape can be further improved.

In the aforementioned sanitary material, the locking part may be a male member for a hook.

In the aforementioned sanitary material, the winding tape may be configured to be attached along the longitudinal direction of an absorber of the non-woven fabric.

In the aforementioned sanitary material, the winding tape may be configured to be attached along the waist circumference direction of the sanitary material.

The width of the fixed part may become narrower toward both ends in the longitudinal direction.

The fixed part may have a waveform.

A winding tape according to one aspect of the present disclosure is a winding tape configured to be attached to a non-woven fabric, and includes a stretchable part and a locking part provided closer to each of both ends of the stretchable part in the longitudinal direction of the winding tape and configured to be attachable to and detachable from the non-woven fabric.

In the aforementioned winding tape according to the one aspect, the locking part configured to be attachable to and detachable from the non-woven fabric is provided closer to each of both ends of the stretchable material. Therefore, since the locking part which is attachable to and detachable from the non-woven fabric is provided closer to each of both ends of the stretchable part, the attaching position of the winding tape to the non-woven fabric can be changed to a desired position. Therefore, the sanitary material can be wound in a desired manner because the winding tape is stretchable by the stretchable part and the locking position of the locking part can be changed. As a result, the operability of the winding operation of the sanitary material can be improved. Further, the winding tape does not need a section which is unreleasable, so that the position of the winding tape relative to the non-woven fabric can be changed more easily. Therefore, the operability of winding operation of the winding tape can be further improved.

In the aforementioned winding tape, the locking part may include a male member for a hook. In the aforementioned winding tape, a fixed part provided between the pair of locking parts and fixed to the non-woven fabric may be provided.

In the aforementioned winding tape, the fixed part may be made of an adhesive.

The aforementioned winding tape may be roll-shaped before being attached to the non- woven fabric.

In the aforementioned winding tape, the tensile strength of the stretchable part may be not less than 10 N/25 mm.

Advantageous Effects of Invention

According to one aspect of the present disclosure, the operability of the winding operation can be improved.

Detailed Description

Hereinafter, embodiments for implementing a sanitary material and a winding tape according to the present disclosure will be described in detail with reference to the

accompanying drawings. In the description of the drawings, the same or corresponding elements are denoted by the same reference numerals, and overlapping descriptions are omitted appropriately. In addition, the drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios, etc. are not limited to those illustrated in the drawings.

As used herein, the term "winding tape" refers to a tape that fastens a rounded sanitary material, and includes, for example, a waste tape that fastens a rounded sanitary material to be discarded in a rounded state. "Rounded" refers to the state of being consolidated, such as by rounding, folding, or rolling. "Sanitary material" is used to maintain sanitary condition, including, for example, disposable equipment. "Sanitary material" includes, for example, absorbent articles such as disposable diapers, sanitary napkins, and incontinence pads, as well as sanitary articles such as hemostatic tapes.

"Non-woven fabric" indicates a fabric formed by bonding or entangling fibers by a mechanical action or a chemical action. "Absorber" indicates a section or a member capable of absorbing liquid. "Fixed part" indicates a portion or a member fixed to an object, and the "locking part" indicates a portion or a member to be locked to an object. "Lock" indicates that an object is removably attached, and includes a state where two objects are fastened in a fixed state.

"Stretchable part" indicates a stretchable aspect, for example, a portion or a member that can be changed to an arbitrary length by stretching with a finger or the like. "Hook" indicates a section or a member for hooking an object. "Male member for a hook" indicates, for example, a plurality of fine protruding sections provided on a mechanical fastener or the like, and "Female member for a hook" indicates a plurality of fine ring-shaped sections on which the male hooks are hooked.

FIG. l is a front view schematically illustrating a sanitary material 1 and a winding tape 10 according to an embodiment. FIG. 1 illustrates a sanitary material 1 which is a pants-type diaper as an example. However, the sanitary material 1 as a diaper may be a tape type (open type), a pad type, or the like, and the type of the diaper may be appropriately changed.

For example, the sanitary material l is a disposable diaper. The sanitary material 1 includes a waist opening 2 extending in the waist circumference direction, a pair of leg openings 3, and an absorber 4 positioned between the pair of leg openings 3. The sanitary material 1 includes an abdominal side 6 (refer to FIG. 8B) and a back side 5 positioned on the rear side of the abdominal side 6, and for example, a winding tape 10 is attached to a non-woven fabric N constituting the back side 5. The absorber 4 has a rectangular shape, for example, and extends from the abdominal side 6 toward the back side 5.

The winding tape 10 is attached, for example, along the longitudinal direction of the absorber 4. The winding tape 10 includes a fixed part 11 fixed to the non-woven fabric N, stretchable part 12 provided on each of both sides in the longitudinal direction D of the winding tape 10 of the fixed part 11, and a pair of locking parts 13 provided respectively on both sides in the longitudinal direction D of the stretchable parts 12. The locking part 13 may or may not reach the end portion of the winding tape 10 in the longitudinal direction D. For example, the fixed part 11 is a section fixed to the non-woven fabric N in a region including the center in the longitudinal direction D of the winding tape 10. The locking part 13 is a section which is attachable to and detachable from an arbitrary position of the non-woven fabric N, for example.

The fixed part 11 may be made of, for example, an adhesive or a pressure-sensitive adhesive (PSA). However, the fixed part 11 may be a welding part fixed to the non-woven fabric N by welding, an adhesive part fixed to the non-woven fabric N by a hot melt adhesive, or a section fixed by a powder-type heat welding resin (PE powder). Thus, the material of the fixed part 11 is not particularly limited. The fixed part 11 is fixed to the non-woven fabric N unreleasably, for example. However, the fixed part 11 may be fixed to the non-woven fabric N releasably, and may be constituted by a PSA having a re-releasable property.

The stretchable part 12 is, for example, a single-layer elastic film. The stretchable part 12 may have a three-layer structure including a core layer containing elastomer and skin layers provided on both main surfaces of the core layer. The material of the skin layer of the stretchable part 12 is, for example, polypropylene resin (PP), but can be appropriately changed.

The stretchable part 12 includes an elastomer, and the elastomer in the stretchable part 12 includes, for example, an olefmic elastomer, a styrene-isoprene block copolymer (SIS), and a polyurethane-based thermoplastic elastomer. However, the material of the stretchable part 12 is not particularly limited. For example, the thickness of the stretchable part 12 may be from 5 pm to 500 pm, from 20 pm to 200 pm, or 40 pm as an example. As illustrated in FIG. 2 A, for example, the winding tape 10 has a rectangular shape extending in the longitudinal direction D and the width direction B. As an example, a fixed part 11 is provided at the center in the longitudinal direction D of the winding tape 10, and a stretchable part 12 and a locking part 13 are provided on each of both sides in the longitudinal direction D of the fixed part 11 with the fixed part 11 as a starting point. Each locking part 13 is provided further closer to each of both ends of the stretchable part 12 in the longitudinal direction D, and is provided at both ends of the winding tape 10 in the longitudinal direction D, as an example.

In the example illustrated in FIG. 2A, the fixed part 11 has a circular shape. A width W1 (a length in the width direction B) of the fixed part 11 becomes narrower toward the both ends in the longitudinal direction D of the winding tape 10. That is, empty portions P formed on both sides in the width direction B of the fixed part 11 becomes wider toward the both ends in the longitudinal direction D. As a result, it is possible to easily change the direction of the stretchable part 12 with the fixed part 11 as a starting point. That is, since the stretchable part 12 is stretchable, the direction in which the stretchable part 12 extends can be changed with the fixed part 11 as the starting point.

The shape of the fixed part 11 is not limited to the aforementioned circular shape, and may be a polygonal shape (a quadrangular shape or a rhombic shape as an example) as illustrated in FIG. 2B. In this case as well, the width W1 of the fixed part 11 becomes narrower toward the both ends in the longitudinal direction D, that is, each empty portion P of the stretchable part 12 becomes wider toward the both ends in the longitudinal direction D. Thus, the same effect as that of the fixed part 11 of FIG. 2 A can be obtained.

Further, the shape, size, number, material, and aspect of arrangement, of the fixed part 11 are not limited to the above-described examples, and may be appropriately changed. For example, the fixed part 11 may have a waveform. Further, as illustrated in FIG. 2C, the shape of the stretchable part 12 can also be appropriately changed, and may be, for example, a cross shape in which a protruding part 12b protruding in the width direction B is formed. In this case, for example, a locking part 13 may be provided at each end of the protruding part 12b in the width direction B.

The locking part 13 is provided closer to each of both ends of the stretchable part 12 in the longitudinal direction D of the winding tape 10. Here, "longitudinal direction of winding tape" indicates a direction in which the stretchable part extends from the fixed part, and "winding tape having a longitudinal direction" may not have rectangular shape. "Winding tape having a longitudinal direction" includes shapes other than rectangles, such as the cross shape illustrated in FIG. 2C.

That is, the "winding tape having a longitudinal direction" may include at least a portion that extends long, and even when a shape other than the portion extends long in another direction (for example, even when a portion of the winding tape 10 having the longitudinal direction D in the lateral direction extends long in the vertical direction as illustrated in FIG. 2C or the like), the tape having the shape is included in the "winding tape having a longitudinal direction".

The color of the locking part 13 may be different from that of the stretchable part 12, for example. As an example, the color of the stretchable part 12 may be white, and the color of the locking part 13 may be a color other than white (e.g., blue). When the color of the locking part 13 is made different from the color of the stretchable part 12 as such, the locking part 13 can be easily recognized. Additionally, the stretchable part 12 may be transparent and the locking part 13 may be opaque.

The locking part 13 has a quadrangular shape (as an example, a rectangular shape), for example. However, the shape, size, number, and aspect of arrangement, of each locking part 13 can be appropriately changed. As illustrated in FIG. 3, the locking part 13 includes, for example, a base 13b fixed to the stretchable part 12 by interposing an adhesive layer 14, and a male member 13c that is made up of a plurality of protrusions protruding from the base 13b. The locking part 13 is, for example, a hook including the male member 13c. The adhesive layer 14 is, for example, PSA.

The material of the locking part 13 is not limited. The locking part 13 may be made of a non-adhesive material. In this case, even when the locking part 13 is pinched with fingers or the like, the locking part 13 does not adhere to the finger or the like, so that the operability of the operation of winding the sanitary material 1 with the winding tape 10 can be further improved.

For example, the material of the locking part 13 may be a thermoplastic resin, and specific examples thereof may be polypropylene resin (PP), polyethylene resin (PE), vinyl chloride resin (PVC), ethyl methyl methacrylate resin (EMMA), ethyl acrylate resin (EA), and ethylene-vinyl acetate copolymer (EVA) resin, or a mixture of 2 or more thereof, or the like. Moreover, the PE may include low density polyethylene (LDPE), high density polyethylene (HDPE), linear low density polyethylene (LLDPE), or the like. Furthermore, the material of the locking part 13 may be a material in which an additive is added to the resin or the like described above.

Next, an example of a method of manufacturing the sanitary material 1 in which the winding tape 10 is configured to be attached to the non-woven fabric N of the sanitary material 1 will be described with reference to FIGS. 4 and 5. FIG. 4 is a perspective view schematically illustrating a roll-shaped member R1 of the winding tape 10 before being attached to the non- woven fabric N. FIG. 5 is a view schematically illustrating the flow of the non-woven fabric N and the winding tape 10 constituting the sanitary material 1.

As illustrated in FIGS. 4 and 5, the winding tape 10 is a roll-shaped member R1 before being attached to the non-woven fabric N, and a portion extending from the roll-shaped member R1 is cut in the width direction of the portion to form the winding tape 10. The non-woven fabric N of the sanitary material 1 is conveyed from a roll R2, and a winding tape 10 is attached to the conveyed non-woven fabric N (on the back side 5 of the sanitary material 1) at regular intervals.

At this time, for example, the winding tape 10 is attached along the longitudinal direction of the absorber 4. However, the winding tape 10 may be attached along a direction crossing the longitudinal direction of the absorber 4. After the non-woven fabric N to which the winding tape 10 is attached is cut, the sanitary material 1 to which the winding tape 10 is attached is completed.

Next, an example of a method of winding the sanitary material 1 with the winding tape 10 will be described with reference to FIGS. 6 and 7. First, as illustrated in FIG. 6, in a state in which the sanitary material 1 is rounded along the longitudinal direction of the absorber 4, the locking parts 13 each provided at both ends in the longitudinal direction D of the winding tape 10 are pinched with fingers, and the stretchable parts 12 are extended in different directions each other with the fixed part 11 as a starting point. Then, as illustrated in FIG. 7, after each locking part 13 is locked to a position apart from the fixed part 11 of the non-woven fabric N in a state where each stretchable part 12 is stretched, winding of the sanitary material 1 with the winding tape 10 is completed.

FIGS. 8 A and 8B are views illustrating an example of another method of winding the sanitary material 1 with the winding tape 10. As illustrated in FIG. 8 A, each of the pair of locking parts 13 of the winding tape 10 fixed to the back side 5 is pinched, and each of the pair of stretchable parts 12 is rotated in a direction crossing the longitudinal direction of the absorber 4 (as an example, a direction orthogonal to the absorber 4). Then, for example, the back side 5 is folded on the abdominal side 6, and each locking part 13 is extended onto the folded back side 5 and the abdominal side 6, and the respective locking parts 13 are locked to both sides of the back side 5 to complete winding of the sanitary material 1 with the winding tape 10. After winding of the sanitary material 1 is completed, for example, the sanitary material 1 wound with the winding tape 10 is stored in a bag, and the bag in a bound state is discarded in a dust box or the like. Next, the action and the effect of the sanitary material 1 and the winding tape 10 according to the present embodiment will be described.

In the sanitary material 1, the stretchable part 12 stretches with the fixed part 11 as a starting point, and each locking part 13 configured to be attachable to and detachable from the non-woven fabric N is provided closer to each of both ends of the stretchable part 12. Therefore, since the stretchable part 12 stretches with the fixed part 11 as the starting point, the position of the winding tape 10 can be extended to a desired position of the non-woven fabric N. As a result, the sanitary material 1 can be wound in a desired winding manner. That is, since the direction in which the winding tape 10 extends can be changed by changing the direction in which the stretchable part 12 extends from the fixed part 11, the sanitary material 1 can be wound in various winding manners. Therefore, the operability of the winding operation of the sanitary material 1 can be improved.

Further, since the locking part 13 is provided closer to each of both ends of the stretchable part 12, the stretchable part 12 can be extended to an arbitrary position and the locking part 13 can be locked to the non-woven fabric N at the arbitrary position of the non- woven fabric N. Therefore, by changing the length and the direction of the winding tape 10 when extending the stretchable part 12, the locking position of the locking part 13 with respect to the non-woven fabric N can be appropriately changed. That is, the locking part 13 can be locked at an arbitrary position of the non-woven fabric N. Therefore, the operability of the winding operation of the winding tape 10 can be further improved.

The locking part 13 may include a male member 13c of the hook. In this case, since the locking part 13 is not adhered to the finger or the like, the operation of winding the winding tape 10 around the sanitary material 1 can be performed more efficiently.

The winding tape 10 may be attached along the longitudinal direction of the absorber 4.

In this case, the process of placing the winding tape 10 on the non-woven fabric N can be easily performed in the manufacturing process of the sanitary material 1. Therefore, the sanitary material 1 can be easily manufactured. Further, the winding tape 10 may be attached along the waist circumference direction (e.g., in a direction orthogonal to the longitudinal direction of the absorber 4.) of the sanitary material 1.

As illustrated in FIGS. 2A and 2B, the width W1 of the fixed part 11 may become narrower toward both ends in the longitudinal direction D of the winding tape 10. In this case, since the fixed part 11 becomes thinner toward both ends in the longitudinal direction D, it is possible to easily rotate the stretchable part 12 with the fixed part 11 as a reference. Therefore, since the stretchable part 12 can be easily extended in an arbitrary direction, operability can be further improved. Further, the fixed part 11 may have a waveform.

The winding tape 10 may include a fixed part 11 provided between a pair of locking parts 13 and fixed to the non-woven fabric N. In this case, a fixed part 11 is provided between a pair of locking parts 13 and a pair of stretchable parts 12. Therefore, the position of the winding tape 10 can be stabilized in the fixed part 11 while the winding tape 10 can be extended in an arbitrary direction and an arbitrary position.

In the winding tape 10, the fixed part 11 may be composed of an adhesive. In this case, the fixed part 11 can be easily fixed by the adhesive in the manufacturing process of the sanitary material 1.

The winding tape 10 may be roll-shaped before being attached to the non-woven fabric N. In this case, it is possible to easily manufacture and manage the winding tape 10.

In the winding tape 10, the tensile strength of the stretchable part 12 may be not less than 10 N/25 mm. The tensile strength of the stretchable part 12 is a value when the tensile direction is the width direction B, the length (distance between the chucks) in the width direction B is 25 mm, and the chuck speed is 50 mpm. In this case, since the strength of the stretchable part 12 is not less than 10 N/25 mm, the possibility of the stretchable part 12 being torn off when pulled can be further reduced.

Next, a winding tape 20 according to another example will be described with reference to FIG. 9. FIG. 9 is a view illustrating an example of the sanitary material 1 to which the winding tape 20 is attached. The winding tape 20 is different from the aforementioned winding tape 10 in that the winding tape 20 does not include the fixed part 11. In the following, the description that overlaps with the aforementioned winding tape 10 will be appropriately omitted. The winding tape 20 includes a stretchable part 12 and a locking part 13 provided closer to each of both ends of the stretchable part 12 in the longitudinal direction D of the winding tape 20. Since the winding tape 20 does not include a section which is unreleasable from the non-woven fabric N, for example, the winding tape 20 can be moved to an arbitrary position of the non-woven fabric N.

Next, an example of a method of winding the sanitary material 1 with the winding tape 20 will be described with reference to FIGS. 9, 10A and 10B. First, as illustrated in FIG. 9, the winding tape 20 is disposed on the non-woven fabric N of the back side 5 so that the winding tape 20 extends in a direction crossing the longitudinal direction of the absorber 4. At this time, for example, the respective locking parts 13 positioned closer to each of both ends in the longitudinal direction D of the winding tape 20 are attached to the non-woven fabric N. Next, as illustrated in FIGS. 10A and 10B, one of a pair of locking parts 13 attached to the non-woven fabric N is pinched with fingers or the like to extend the stretchable part 12 in a direction crossing the longitudinal direction of the absorber 4, and the sanitary material 1 is rounded along the longitudinal direction of the absorber 4 so that the abdominal side 6 faces inward and the back side 5 faces outward. The extended stretchable part 12 and one locking part 13 are wound around the opposite side of the other locking part 13 to lock the one locking part 13 to the non-woven fabric N. In this way, one locking part 13 is wound around the opposite side of the other locking part 13 to be locked to the non-woven fabric N, thereby winding of the sanitary material 1 with the winding tape 20 is completed.

FIGS. 11, 12A and 12B are views illustrating another method of winding the sanitary material 1 with the winding tape 20. As illustrated in FIG. 11, the winding tape 20 is arranged on the non-woven fabric N of the back side 5 so that the winding tape 20 extends along the longitudinal direction of the absorber 4. Then, as illustrated in FIG. 12A and FIG. 12B, one of the pair of locking parts 13 is pinched with fingers or the like to extend the stretchable part 12 in the longitudinal direction of the absorber 4, while the non-woven fabric N is rounded in the longitudinal direction, and the one locking part 13 is locked to the rounded non-woven fabric N. In this way, one of the locking parts 13 is locked to the rounded non-woven fabric N, and winding of the sanitary material 1 with the winding tape 20 is completed.

As described above, the winding tape 20 includes the respective locking parts 13 configured to be attachable to and detachable from the non-woven fabric N closer to each of both ends of the stretchable part 12. Therefore, since the locking parts 13 configured to be attachable to and detachable from the non-woven fabric N are provided closer to each of both ends of the stretchable part 12, the attaching position of the winding tape 20 to the non-woven fabric N can be changed to an arbitrary position. Therefore, the sanitary material 1 can be wound in a desired manner because the winding tape 20 is stretchable by the stretchable part 12 and the locking position of the locking part 13 can be changed. As a result, the operability of the winding operation of the sanitary material 1 can be improved. Further, since the winding tape 20 does not include a section which cannot be released, the position of the winding tape 20 itself can be changed. Therefore, the operability of the winding operation of the winding tape 20 can be further improved.

Embodiments of the sanitary material and the winding tape according to the present disclosure have been described above. However, the present invention is not limited to the aforementioned embodiments. The present invention can be variously modified without changing the gist of the claims. For example, as described above, the shape, size, number, material and the aspect of arrangement, of each part constituting the sanitary material and the winding tape can be appropriately changed. For example, in the above embodiment, the fixed part 11 of circular or polygonal shape has been described. However, the shape of the fixed part may be an oval shape including an ellipse, a waveform shape, or the like, and may be appropriately changed.
