The handle 10 of the present embodiment has an elliptical cross-sectional shape and is composed of a rod-shaped member having a thickness (for example, a width of about 10 to 20 mm) that is easy to grip by hand. The cross-sectional shape of the handle 10 may be an elliptical shape, for example, a rectangular shape, a polygonal shape, a circular shape, or the like. The handle 10 is made of a material having corrosion resistance, such as resin or a metal such as stainless steel. The handle 10 is preferably made of a material having elasticity such that appropriate bending occurs during the operation of gripping and cleaning the handle 10.

The length of the handle 10 is arbitrary, but it has a length corresponding to the depth of the deep bottom container (water bottle, various bottles, pots, etc.) which is the object to be cleaned in the case of the present embodiment, for example, 300 mm. The length is set to about 400 mm in the front and back. Further, the handle 10 is preferably configured to be expandable and contractible in that it can be used for containers of various depths.

The overall shape of the cleaning body 20 has a substantially prismatic shape centered on the handle 10. Hereinafter, the extending direction of the handle 10 is referred to as an axial direction. The cleaning body 20 has a core portion 30 and a plurality of (in this case, four) cleaning portions 40 laminated on the outer periphery of the core portion 30. The cleaning body 20 has an appropriate size that can be put in the deep bottom container, and is set, for example, in a range of an outer diameter of about 20 to 70 mm and a length of about 30 to 150 mm.

The core portion 30 of the present embodiment is made of an elastic sponge. By using a sponge for the core portion 30, the cleaning body 20 can sufficiently retain detergent and water and can foam well. As the sponge constituting the core portion 30, for example, a foam material such as a urethane resin foam, a regenerated cellulose foam, a melamine resin foam, or an olefin resin foam is used.

The cleaning unit 40 is a portion that is slidably contacted with the surface to be cleaned to remove dirt. The cleaning unit 40 of the present embodiment is made of a non-woven fabric having elasticity, and a one-layer non-woven fabric or a laminated one of a plurality of non-woven fabrics is used. The non-woven fabric constituting the cleaning portion 40 has a higher coefficient of friction than the sponge constituting the core portion 30, and is a material suitable for scrubbing so as not to damage the cleaning target portion. As the fibers of the non-woven fabric constituting the cleaning portion 40, for example, polyamide fibers, polyester fibers, polypropylene fibers, polyethylene fibers and the like are used.

In order to enhance the cleaning ability, the cleaning unit 40 may have a configuration in which abrasive particles are dispersedly coated and adhered to the entire exposed surface surface. As the polishing particles, mineral particles such as aluminum oxide, silica and calcium carbonate, and particles made of a resin material such as polyester, polycarbonate and acrylic can be used.

As shown in FIG. 2, each cleaning portion 40 has two edge portions 51 on the circumferential direction side, an edge portion 52 on the base end side, and an edge portion on the tip end side as edge portions for scraping off dirt from the cleaning target portion. It has 53 and.

As shown in FIG. 2, the peripheral edge portions 51 and 51 are formed at one end and the other end in the width direction of the outer surface 41 of the cleaning portion 40, respectively. The edge portions 51, 51 on the circumferential direction side are each composed of the tops of the corner portions having a substantially right-angled triangular cross section formed by the outer surface 41 and each side surface 44, and are directions intersecting in the circumferential direction and have a substantially axial axis. It extends along the direction.

As shown in FIG. 2A, the edge portion 52 on the proximal end side is formed at the proximal end on the handle 10 side in the axial direction of the cleaning portion 40. The edge portion 52 on the base end side includes an edge portion 52a on the outer surface side formed by the outer surface 41 and the end surface 42 on the base end side and formed by the top of a corner having a substantially right-angled triangular cross section, and the outer surface 41 and each side surface. It has a pair of side edge portions 52b formed by the tops of the corners having a substantially right-angled triangular cross section formed by the 44. The edge portion 52a on the outer surface side extends in a direction intersecting the axial direction and along the width direction of the cleaning portion 40. The edge portion 52b on the side surface side extends in a direction intersecting the axial direction and along the thickness direction of the cleaning portion 40.

As shown in FIG. 2B, the edge portion 53 on the tip end side is formed at the tip end on the side opposite to the side on which the handle 10 extends in the axial direction of the cleaning portion 40. The edge portion 53 on the distal end side is formed by the edge portion 53a on the outer surface side formed by the outer surface 41 and the end surface 43 on the distal end side and the tops of the corners having a substantially right-angled triangle shape, and the outer surface 41 and each side surface 44. It has a pair of side edge portions 53b formed of tops of corner portions having a substantially right-angled triangular cross section. The edge portion 53a on the outer surface side extends in a direction intersecting the axial direction and along the width direction of the cleaning portion 40. The edge portion 53b on the side surface side extends in a direction intersecting the axial direction and along the thickness direction of the cleaning portion 40.

The cleaning body 20 according to the present embodiment can be configured by, for example, combining two rectangular parallelepiped blocks 25 shown in FIG. 3A. The blocks 25 and 25 have a structure in which the cleaning body 20 is divided into two, and the cleaning body 40 is laminated on both sides of the rectangular parallelepiped sponge 35 forming the core portion 30 described above. It is constructed by laminating each of the non-woven fabrics 45 having a predetermined thickness. In this embodiment, the handle 10 is used as a means for combining the blocks 25 and 25.

As shown in FIG. 3B, the handle 10 has a bifurcated holding portion 11 at its tip. The bifurcated holding portion 11 has a pair of holding pieces 12 formed integrally with the handle 10. By having the bifurcated holding portion 11, the tip portion of the handle 10 is formed in a substantially Y shape.

By compressing and sandwiching the sponges 35 and 35 between the sandwiching pieces 12 of the bifurcated sandwiching portion 11, the cleaning body 20 is formed at the tip of the handle 10, and the cleaning body 20 is held by the handle 10. It has become like. Each holding piece 12 is elastically deformable in a direction approaching and a direction away from each other. On the inner surface of each holding piece 12 in contact with the sponges 35, 35, a plurality of convex portions 12a, which are locked by the sponges 35 and 35 and prevent the cleaning body 20 from coming off the handle 10, are formed. In this case, the convex portion 12a is formed in a hook shape that protrudes toward the side opposite to the tip end side so that the handle 10 is surely prevented from coming off.

As shown in FIG. 3B, the two blocks 25, 25 are aligned so that the side surfaces of the sponges 35, 35 are in contact with each other, and the sponges 35, 35 are between the holding pieces 12 of the bifurcated holding portion 11. The handle 10 and the blocks 25 and 25 are moved in a relatively close direction so as to be pushed into the fork, and the sponges 35 and 35 are sandwiched between the bifurcated holding portions 11.

As the sponges 35 and 35 are compressed by the bifurcated sandwiching portions 11, the blocks 25 and 25 change their shapes so that the four cleaning portions 40 are arranged radially as shown in FIG. 4, and one cleaning body is formed. It is formed at 20. Due to the elastic force of each sponge 35 trying to elastically return to its original shape, the two sponges 35 are in a state of being crimped to each other, each sponge 35 is sunk into each holding piece 12, and the cleaning body 20 is held by the handle 10. Will be done.

In FIG. 4, the core portion 30 composed of the two sponges 35 and the cleaning portion 40 composed of the four non-woven fabrics 45 are uniformly illustrated with a rectangular cross section, but the sponge 35 is bifurcated. It is compressed and deformed by the portion 11, and the non-woven fabric 45 is also deformed following the compressed sponge 35. Therefore, the cleaning body 20 does not actually have a uniform shape. For example, the core portion 30 is formed into a columnar shape, and the outer surface 41 of each cleaning portion 40 is deformed into a curved surface along the circumferential direction. May be done.

In the present embodiment, by combining the two blocks 25 with the handle 10 as described above, the result is a three-dimensional cleaning body 20 in which the four cleaning portions 40 are arranged radially. The structure of the cleaning body 20 is not limited to this. For example, a rectangular parallelepiped core portion 30 is formed in advance with a sponge, and four strip-shaped cleaning portions 40 are joined to the outer peripheral portions of the four surfaces of the core portion 30 to form a three-dimensional cleaning body 20. The structure may be such that the tip portion of the handle 10 is pierced and joined to the core portion 30 of the cleaning body 20.

Therefore, in the cleaning tool 1 according to the present embodiment, the inner peripheral surface 110a of the bottle 100 can be easily and efficiently cleaned by the cleaning unit 40 made of a non-woven fabric having high cleaning power, and the usability is improved.

In addition, each edge portion 51, 52, and 53 of the cleaning portion 40 can be used for cleaning by scraping off dirt. Therefore, as described above, it is possible to effectively remove stains that are difficult to remove (for example, stains that are stuck to tea astringents, scales, etc.) at the locations where the edge portions 51, 52, and 53 are in sliding contact with each other. In particular, the inner surface 120a of the shoulder portion 120 and the portions where it is difficult to contact the outer surface 41 of the cleaning portion 40 such as the inner corner portions 120b and 130b are also scraped off by using the edge portion 52 on the base end side and the edge portion 53 on the tip end side. The dirt can be removed.

Further, in the cleaning tool 1 according to the present embodiment, since the cleaning body 20 has a core portion 30 made of a sponge, the detergent is sufficiently foamed by kneading the core portion 30 impregnated with water and the detergent and repeating compression. As a result, the detergency can be improved.

Further, the cleaning tool 1 according to the present embodiment constitutes the cleaning body 20 by combining two blocks 25 obtained by dividing the cleaning body 20 by a handle 10. By combining the two blocks 25 to form the cleaning body 20 in this way, the three-dimensional cleaning body 20 can be easily formed.

Further, in the cleaning tool 1 according to the present embodiment, since the uniting means for combining the two blocks 25 is the handle 10, a member for combining the two blocks 25 is not required, and the configuration can be simplified.

Each non-woven fabric 47 is laminated on the outer peripheral surface of the core portion 30 at equal intervals in the circumferential direction by a joining means such as adhesion. Further, the handle 10 in this case has a tapered tip portion which is not bifurcated, and a plurality of hook-shaped convex portions 10a for preventing the handle from coming off are formed on the side surface thereof. The tip of the handle 10 on which the plurality of convex portions 10a are formed is inserted into the slit 30a from one end surface of the core portion 30 and arranged at the center of the core portion 30 so as to be adhered to the core portion 30. ing. In the illustrated example, the number of the cleaning portions 40 made of the non-woven fabric 47 is three, but the number is arbitrary, and the inclination angle with respect to the axial direction is also arbitrary and is appropriately set.

Further, in the cleaning body 20 shown in FIG. 14A, three cleaning portions 40 made of a non-woven fabric 48 cut into a curved shape are spirally wound around the outer peripheral portion of the columnar core portion 30 shown in FIG. It is a joint. Each cleaning portion 40 has a peripheral edge portion 56 that intersects in the circumferential direction. As shown in FIG. 14B, the core portion 30 and the handle 10 have the same configuration as that shown in FIG. 13, and the handle 10 is inserted into the core portion 30 and adhered. In the illustrated example, the number of the cleaning portions 40 made of the non-woven fabric 48 is three, but the number is arbitrary, and the degree of curvature of the non-woven fabric 48 is also arbitrary and is appropriately set.

In the cleaning body 20 shown in FIGS. 13 and 14, the outer surface 41 of each cleaning unit 40 constitutes an outer peripheral surface 21 over the entire circumference of the entire cleaning body 20. Then, the dirt on the inner peripheral surface 110a of the bottle 100 can be scraped off by the edge portions 55 and 56 on the circumferential direction side, respectively, and the cleaning effect is improved.

INDUSTRIAL APPLICABILITY The present invention can easily and efficiently clean the entire circumference of the inner surface of a container with a non-woven fabric having high detergency, and is useful as a cleaning tool with improved usability.
