Description

DISPOSABLE REMEDY FOR MECHANICAL REMOVAL

POLLUTION

Technical field

The present invention relates to cleaning and hygiene in relation to industrial and domestic tasks, where it is required to perform mechanical cleaning of the surface from contamination.

State of the art

In industry and everyday life there are many tasks of cleaning surfaces from pollution. So in industry this may relate to the removal of oily contaminants from the surfaces of machine components and assemblies, and in everyday life - the removal of human and animal waste products (feces) in a plumbing assembly and rooms.

In such cases, a person, along with chemical and aqueous media, uses various devices for mechanical impact on pollution. Existing devices most often are brushes with a pile of various stiffness or foam sponges.

However, in some cases, the contamination is such that the brush itself becomes an object for long-term cleaning after use. For example, the removal of tar or other compressed oily formations. In others, the brush leaves particles of former surface contaminants (remaining after previous cleaning), which, as a source of infection, damage the human immune system. This, in particular, is about household brushes for cleaning the toilet, which are constantly present in the toilet. The use of various containers with disinfectant liquids, where such brushes can be stored in toilets, are not popular. That is, they are not used in most cases due to the inconvenience of spraying and dropping drops and particles of infection on the toilet seats when using them.

The use of foam sponges is also associated with the need for subsequent cleaning, and also requires the use of hand-held protective agents against contact with infection.

Often in everyday life, a person needs to remove the tray with the waste products of domestic animals. To clean such trays, various plastic spatulas are used, which must be cleaned in turn, otherwise they also become sources of infection. The same pets sometimes do not use trays, preferring leave their traces (feces, vomiting, etc.) on the floor in the living room. It is also relevant tool for the effective mechanical removal of the main part of the contamination, leaving a small task to wet wipes.

Also, it would be important for housewives to be able to remove dense dirt in the sinks, both in the kitchen and in the bathroom. Here, housewives are forced to use reusable brushes and other devices, also with the subsequent necessary cleaning of the cleaning agents themselves.

There are solutions that allow changing the cleaning blocks, leaving the handles for future use. There are also two drawbacks. Firstly, it is necessary to remove removable blocks, which, on the other hand, must be effectively held on the handle for their use, which cannot always be combined in an effective way. Secondly, the handle itself is forced to come into contact with the pollution or the environment in which the pollution is disposed of, which obliges the user to resort to additional cleaning procedures of the cleaning agent itself - the handle.

The urgent task is to create a tool for mechanical cleaning of surfaces in industry and everyday life, ideally with the possibility of subsequent removal of the product through the sewer of a disinfected object in compliance with the environmental disposal standards of modern society. This problem is solved by the present invention.

Disclosure of the invention.

The technical result, the achievement of which the claimed invention is directed, is to ensure accessibility and increase the efficiency of using specialized tools for the mechanical removal of contaminants from surfaces.

The specified technical result is achieved by the fact that in a disposable tool for mechanical removal of contaminants containing at least two functional parts: a handle and a scraper, each of the functional parts is made of a material that is soluble in the environment of the removed pollution for a time commensurate with the time possible use of a disposable product. In addition, the handle and the scraper may have different ability to dissolve when interacting with the standard disposal environment, the scraper may consist of sections of different profiles and areas showing different ability to dissolve when interacting with the standard disposal environment. The specified technical result is also achieved due to the fact that the tool can be made of more than one material, more than one impregnating solution and at least one surfactant and / or at least one antiseptic substance can be used. and / or at least one substance that promotes the functions of the disposal media and / or treatment systems.

The present invention is aimed at creating conditions for effective use and familiarization with the culture of hygiene through the disposability of the product, its accessibility, functionality and ease of use. In other words, the present invention provides a disposable tool for mechanically removing contaminants from surfaces (hereinafter, in the description of the description of the invention, "tool")

To solve these problems, the present invention provides a tool for mechanical removal of contaminants, containing two functional parts: a handle and a scraper, which has the ability to become less dense in consistency in the environment of standard disposal of the removed pollution than the removed pollution over time, commensurate with the time of its possible use. The design of the handle may have a constructive solution that increases its strength properties. At the same time, the handle and scraper can exhibit different properties when interacting with the standard disposal environment. Also provided is a tool in which the scraper consists of sections of different designs and / or consists of sections exhibiting different properties when interacting with a standard disposal environment.

The present invention provides the possibility of using more than one material for the manufacture of tools and more than one solution, which is impregnated with different parts of the handle and scraper tools in its manufacture.

The best embodiment of the invention.

Disposable means for mechanical removal of contaminants can be of various shapes and purposes. Its two main functional parts are the handle (handle), for which the user holds it and to which it transfers its effort, and a scraper that senses the user's effort indirectly through the handle and directly carries out mechanical cleaning of the dirt.

To describe the present invention, we will explain the following expression (phrase): "in a standard environment for disposal of contaminated waste." By this, for example, we mean water, if we speak with respect to a tool from compressed paper to remove contaminants from human waste products (feces) in the toilet. By the term “standard” medium we mean “generally accepted” or “frequently used” medium.

If we are talking about a tool from biopolymer or bioplastics to remove organic contaminants, for example, partially hardened residues of food, tar or tar (when washing dishes, containers, etc.), then the indicated “medium” will be that alkaline or acid composition of the surface active substance, which is standardly used in such cases (dishwashing detergents, containers, etc.).

To describe the present invention, we will clarify the following expression (phrase): "become less dense in consistency than the removed contamination." This in relation to the tool will mean that it loses its stiffness, dissolves, softens, disintegrates into parts, etc. For brevity of presentation, in the future we will denote this ability of the product by the term “dissolve” (or the essence of the phenomenon is “dissolution”).

For example, compressed paper, which for mechanical strength, like papier-mâché, is impregnated with some kind of water-soluble solution (for example, starch), will behave this way after interacting with water: it dissolves into its small pieces of paper, which is then easy removed by standard sewer.

To describe the present invention, let us explain the following expression (phrase): "for a time commensurate with the time of its possible use" in relation to the tool. It means that the time during which the product dissolves cannot exceed the time during which the product can still be a tool for cleaning, by one or more orders of magnitude (that is, be 10 or more times longer).

For example, cleaning a toilet bowl from human waste products or other material takes from a few seconds to 1-2 minutes. So the maximum "proportionate" time is considered to be 10-20 minutes. Although preferred According to the present invention, the period of time will be a few seconds after the product is immersed in water.

Another example, if a means of biopolymer or bioplastics can, working continuously, remove contaminants from surfaces within a few hours, then such a tool should dissolve no longer than a day.

Moreover, it is obvious that the dissolution time of the product must exceed the time of its use.

The simplest embodiment of the means is shown in FIG. 1a. This is a cylindrical design, where there is no visual design difference between the two functional parts of the Tool (handle and scraper).

More complex in design terms may be options with a scraper in the form of flat blades of different longitudinal and transverse dimensions, depicted in figs and d. Moreover, they may have an identical cylindrical handle (Fig. Lb).

The handle may have a lightweight construction using special constructive solutions (structures), for example, cylindrical and hollow inside (Fig. 2a), hollow triangular (Fig. 2b), eight-pointed (Fig. 2c) or four-pointed (Fig. 2d) in cross section. This set of possible options for known solutions is not limited. To increase the effectiveness of the Tool in its manufacture, any known constructions and structures can be used that, with the minimum volumetric content (weight) of the material used to manufacture the tool, give the tool maximum mechanical strength in the necessary directions of application of force.

A scraper in the form of blades can have segments that can differ from each other by the degree of softening when interacting with the standard disposal medium (Fig. 3, b, c). This set of possible options for known solutions is not limited. Also, they can be separated by gaps (sections of the product marked in FIGS. B, B, with thinning and dark color), which have a different degree of softening, which increases the functionality of the product when used.

The best option for implementing tools for use when cleaning the toilet is as follows. From boiled paper of recycled materials with the consistency of ordinary toilet paper, a blank with a handle profile shown in FIG. 2d, and with the profile of the scraper shown in FIG. 3b, where the “scapular" part of the scraper has four segments separated by special profile gaps 301, and the cylindrical part of the scraper has two segments separated by a special profile interval 302. Accordingly, different sections of such a preform are impregnated with different degrees of density of solutions, the number of which may be more than one and which performs two functions. The first to give rigidity to the structure. The second is to provide a different degree of susceptibility to water, that is, a different rate of softening and dissolution of the material. So, the handle of such a tool should have the maximum possible rigidity and maximum ability to soften. Sites should be able to be susceptible to water, that is, absorb water, losing their rigidity, but not dissolve quickly. Finally, narrow sections of the scraper, special profile gaps 301 and 302, should in this embodiment have the greatest resistance to water from all sections of the product. These areas will take on the main mechanical force of the hand, mediated (transmitted) through the upstream still dry segments of the scraper and handles. The softened segments between the indicated spaces 301 and 302 will retain water to improve the mechanical impact of these spaces.

This design will allow the user using the scapular part of the scraper to remove contaminants from straight (planar) surfaces, on which he will alternately pass, soaking one segment after another. If the surface of the toilet closes with each other at right angles, then formed, thus, the internal angle can be cleaned by the end face 303 of the scapular portion of the scraper. If, however, the angle between the flat sections of the toilet bowl is smoothed and represented by a circle, then the user will be able to dip the tool deeper, reaching the cylindrical part of the scraper, with which to clean the surrounding surface. At the same time, the presence of the conical part 304 of the cylinder during the transition from the scapular to the cylindrical parts of the scraper or the cylindrical part of the handle itself, for example, between a special profile gap 302 and the conical part 304, will allow to cope with any radius of the circumferential surface area.

As a material for the manufacture of the product, any of the existing organic materials based on cellulose, bioorganic polymers, bioplastics, and other materials soluble in the environment for the standard disposal of contaminated materials can be used. Also, in the manufacture of one product of the product, combinations of these materials can be used.

Solutions used for impregnation / preparation of the agent may additionally have antiseptic properties. Also, these solutions may have the ability to dissolve contaminants that existing surfactants possess. substances used to dissolve and remove contaminants in industry and everyday life.

In the manufacture of the product, the properties of the solutions must be taken into account in order to have a minimal negative effect on the disposal system (sewage, cleaning), such as having minimal adhesive properties or properties that neutralize the actions of the treatment systems. Whenever possible, they should facilitate disposal in standard environments and treatment systems.
