DISPOSABLE BRUSH

DESCRIPTION OF THE UTILITY MODEL

The utility model relates to household items, namely tools for washing and cleaning [A46ВЗ/00, А46ВЗ/04, А46В5/00, А46В5/02, A46D1/00, A46D1/05, А47К11/10, А47К17/00, A46D1 /0215],

Disposable TOILET CLEANING DEVICES are known from the prior art [RO131184 (JSC), publ.: 06/30/2016], made of water-soluble paper having a conical shape, with a base cut at a certain angle relative to the axis of the cone to facilitate sliding along the walls toilet bowl, small cuts made on the edge of the base of the cone for even better contact with the curved surfaces of the toilet bowl, where the paper these cones are made from can come in different colors and flavors.

Also known is a BIODEGRADABLE BRUSH OR DISPOSABLE SCRAPER FOR CLEANING THE TOILET BOWL [RU163091 (U1), publ.: 07/10/2016], containing a handle and a cleaning area made of biodegradable paper, coated with a substance that slows down premature decomposition, according to a technical solution, as a retarding substance premature decomposition used carbo xymethyl cellulose.

The closest in technical essence is a DISPOSABLE PRODUCT FOR MECHANICAL REMOVAL OF CONTAMINATION [RU173295 (U1), publ.: 08.21.2017], containing a handle and a cleaning area made of biodegradable paper and coated with a substance that slows down premature decomposition, characterized in that the surface of the cleaning section contains protrusions connected to each other by stiffening ribs.

The main technical problem of the analogues and the prototype is the impossibility of using them to clean hard-to-reach places, for example, under the rim of a toilet bowl due to their rectilinear shape; low reliability due to their rectilinear design, as well as low reliability due to weak resistance to deformation under mechanical influence. The purpose of a utility model is to eliminate the shortcomings of the prototype.

The technical result of the utility model is to provide the ability to clean hard-to-reach places and increase reliability.

This technical result is achieved due to the fact that a disposable brush containing a handle and a cleaning part, made of biodegradable paper and coated with a substance that slows down premature decomposition in water, characterized in that the handle and the cleaning part are located at an angle from 90 to 180 degrees with the possibility providing access to hard-to-reach places, while at the bend of the handle there are longitudinal stiffening ribs with the ability to provide rigidity during the mechanical impact of the cleaning part on the surface to be cleaned; a cleaning agent is applied between the layers of the brush material at the end of the cleaning part.

In particular, at the end of the cleaning part there are longitudinal cuts with the possibility of forming bristles to ensure the mobility of the cleaning part and increase the cleaning properties of the disposable brush.

In particular, the cleaning part is integral with the handle.

In particular, the cleaning part is mounted at the end of the handle by a pipe connection by mounting the end of the handle inside the cleaning part or vice versa.

Implementation of a utility model.

The disposable brush is made in the form of a hollow tube made of multilayered biodegradable paper by winding and contains distal and proximal ends. The distal end is configured to form a handle 1 (see Fig. 1-4) of a disposable brush for holding it by hand, and the proximal end is configured to form cleaning part 2 of a disposable brush and mechanical action of its end on the surface to be cleaned, layers of cellulose with low fiber density

Cellulose with low fiber density, which has moisture-absorbing properties, can be used as biodegradable paper. Biodegradable paper can be impregnated with a substance that slows down premature decomposition. Said substance may additionally contain dyes, flavorings and bactericidal substances, as well as fillers.

What is new is that the handle 1 and the cleaning part 2 are arranged at an angle of 90 to 180 degrees by bending the lower part of the handle 1 by pressing. In the place where the handle 1 bends during pressing, longitudinal stiffening ribs 3 are made with the ability to ensure the rigidity of this part of the handle 1 during the mechanical impact of the cleaning part 2 on the surface to be cleaned.

In one embodiment, longitudinal cuts are made at the end of the cleaning part 2 with the possibility of forming bristles 4 (see Fig. 4) to ensure the mobility of the cleaning part 2 and increase the cleaning properties of the disposable brush.

In one embodiment, a cleaning agent in the form of an abrasive, non-abrasive, alkaline or acidic agent is applied between the layers of brush material at the end of the cleaning part 2. In abrasive substances, chalk, quartz sand, pumice, both artificial and natural, etc. are used as the main active ingredients. Non-abrasive products use soda, acids, organic solvents, and phosphates. The cleaning agent can be applied to said end of the cleaning part by impregnation.

In various embodiments of the utility model, the cleaning part 2 can be made integral with the handle 1 or separately. In an embodiment with a separate cleaning part 2, it is mounted at the end of the handle 1 with a pipe connection by installing the end of the handle 1 inside the cleaning part 2 or vice versa, with one of the mentioned parts having a larger diameter (see Fig. 4).

A disposable brush is used as follows.

A disposable brush is held by hand by the handle 1 and mechanical friction is applied with the end of the cleaning part 2 to the surface to be cleaned, for example, the surface of a toilet or sink. To improve the quality of cleaning, the surface to be cleaned is pre-moistened with water. Cleaning part 2 comes into contact with the contaminated part being cleaned. surface, and in an embodiment with a cleaning agent applied between the layers of material of the cleaning part 2, the said agent additionally acts on the places of contamination as a solvent of the contamination or an abrasive and makes it possible to clean the contamination, while, due to the applied substance that slows down premature decomposition, the liquid does not come into contact with the material of the brush and prevents its premature decomposition, and due to the stiffening ribs 3 formed at the bend of the handle 1, it retains its shape from deformation, while the position of the handle 1 at an angle to the cleaning part 2 makes it possible to use the brush to clean hard-to-reach places, for example, under the rim of the toilet, which ultimately ensures the achievement of a technical result - the ability to clean hard-to-reach places and increase reliability.

After prolonged use and degradation of the anti-decomposition agent, the liquid comes into contact with the brush material and causes it to soften and break down into fibers.

After destruction, the brush is disposed of in any known way, including dumping it into the toilet, immersing it in a liquid medium, or leaving it in the environment, with the goal of its rapid and complete self-decomposition in the environment without polluting it.
