(About the overall configuration of toilet bowl cleaning tools)
A toilet bowl cleaning tool according to the present invention will be described below with reference to the drawings showing embodiments.

  In the figure, 1 is a toilet cleaning tool. The toilet bowl cleaning tool 1 is mainly a tool for cleaning the toilet bowl 9 in the toilet bowl. The toilet bowl cleaning tool 1 includes a handle portion 2 for a cleaning operator to hold and a cleaning portion 3 attached to the handle portion 2 to contact and clean the surface to be cleaned in the toilet bowl 9.

  The handle portion 2 is formed of a thermoplastic synthetic resin such as polypropylene. The handle part 2 is formed at one end of the handle, and a gripping part 20 for the cleaning operator to hold, and a fitted hole 21 for attaching the cleaning part 3 formed at the other end of the handle. Is provided.

  The fitted hole 21 includes an opening 210 for attaching the cleaning unit 3, an inner wall surface 211 continuous from the opening 210, an insertion port 212 continuous from the inner wall 211, and an opening edge of the insertion port 212. The latch receiving part 213 which comprises is provided.

  The fitted hole 21 has a shape in which the inner wall surface 211 is continuous so that the width gradually decreases from the opening 210 toward the insertion port 212, and suddenly becomes wider near the opening edge of the insertion port 212. A wide portion is formed as a latch receiving portion 213.

  The cleaning unit 3 includes a core body 30 attached so as to extend from the handle part 2 and an elastic porous material body 31 provided so that the core body 30 serves as a core.

  The core body 30 is made of a thermoplastic resin such as polypropylene and has a substantially band shape in plan view. The core body 30 includes a fitting portion 300 that fits into the fitting hole 21 of the handle portion 2 at the base end with the handle portion 2.

  The fitting part 300 is formed so as to be narrowed toward the base end and to have a substantially triangular shape in plan view. Further, the fitting part 300 includes a crotch part 301 in which a vertex part of a substantially triangular shape in plan view, that is, a base end part branches into a plurality of crotch parts.

  The crotch portion 301 is formed in a hook shape in which the branched tip extends to the outer crotch side. The crotch portion 301 is normally open between the crotch portions. The crotch portion 301 is curved toward the inner crotch side in such a manner that one or all of the crotch bows when stress is applied from the outside. The crotch portion 301 is temporarily bent toward the inner crotch side by being pushed by the inner peripheral wall 211 of the fitted hole 21 and passes through the insertion port portion 212. Then, as shown in FIG. 5A, the crotch portion 301 is released from the inner crotch side immediately after passing through the insertion port portion 212, and the wedge portion at the tip that expands to the outer crotch side is the insertion port portion 212. It is latched on the latch receiving part 213 of the.

  The crotch portion 301 includes a protrusion 302 (obstacle) between the crotch. For example, when the crotch portion 301 is stressed from the outside while being fitted in the fitted hole 21, as shown in FIG. 5B, the entire crotch portion is twisted so that one crotch is directed toward the other crotch. It curves like a big bow. At this time, when one crotch comes into contact with the protrusion 302 protruding from the other crotch, the curving of the one crotch toward the inner crotch side is regulated so as not to exceed a certain level. As a result, the crotch portion 301 can be prevented from being inadvertently detached from the latch receiving portion 213.

  Further, the core body 30 includes a notch portion 303 whose middle portion is narrow in plan view. Note that the function of the notch 303 will be described later.

  Further, the core body 30 is formed so as to be bent upward from the base end to the tip end of the handle portion 2 so as to have a shape substantially in a side view. Further, the core body 30 is formed so that the thickness of the portion that bends upward (hereinafter referred to as “bent portion 304”) is thinner than other portions, and the surface of the core body 30 to be cleaned in the toilet bowl 9 by the cleaning operator is formed. It has the flexibility to bend and deform further upward according to the pressing force. The core body 30 is formed with a thickest tip so that the elastic porous material body 31 attached around the core body 30 is not damaged.

  The elastic porous material body 31 is a material having open cells, and is formed of, for example, a synthetic resin such as polyurethane, polyethylene, and melamine. Further, the elastic porous material body 31 has a substantially plate shape in plan view, and has a two-layer laminated structure of a dense portion 310 having a predetermined number of bubbles and a rough portion 311 having a smaller number of bubbles than the dense portion 310. Yes. Here, the “number of bubbles” means the number of bubbles per unit length (25 mm) of the elastic porous material, and the larger the number of bubbles, the more clogged the state.

  In addition, the elastic porous material body 31 is folded in half so that the core body 30 is sandwiched from the plan view side and the bottom view side, and in this state, an adhesive is applied to the opposing surfaces and bonded and fixed. Further, the elastic porous material body 31 is prevented from being caught by the notch portion 303 of the core body 30 and being pulled out of the core body 30 by bonding and fixing opposing surfaces (see FIG. 2). .

  In addition, the elastic porous material body 31 is attached to the core body 30 so that the dense portion 310 is an outer layer in a state where the opposing surfaces are bonded and fixed. Since the elastic porous material body 31 includes the dense portion 310 and the rough portion 311, the dense portion 310 has an excellent frictional force with the surface to be cleaned, and reliably removes dirt, and the rough portion 311. However, it has excellent air permeability and facilitates quick storage and storage in a storage case.

  In addition, the elastic porous material body 31 is regulated by the shape of the core body 30 to be a core and has a shape substantially in a side view, and further follows the shape change due to the flexibility of the core body 30. It bends and deforms. The elastic porous material body 31 is easy to come into contact with the surface to be cleaned in the curved toilet bowl 9, and the entire toilet bowl can be reliably and efficiently cleaned. As shown in FIG. The bent portion 304 is greatly bent according to the pressing force against the surface to be cleaned and easily enters the inner corner portion 93 of the water return portion 92 of the downward opening, and this portion can be reliably and efficiently cleaned.

  In the above-described embodiment, the case where the cleaning unit 31 enters the inner corner portion 93 of the water return portion 92 in the toilet bowl 9 has been described as an example. However, this invention is not limited to this, You may clean the inside of a toilet bowl provided with another shape.

  For example, a recent Western-style toilet has a configuration in which washing water flows in a spiral shape from the water outlet of the top peripheral edge 91 of the toilet bowl 9 to the drain outlet of the bowl bottom, and flows uniformly in the toilet bowl 9. There is. In the toilet bowl cleaning tool 1 according to the present invention, when the elastic porous material body 31 is crushed in the width direction, it can enter the water outlet of the narrow toilet bowl 9 and reliably clean around the water outlet. it can.
