Description

A CLEANING TOOL WITH INTEGRATED DETERGENT CONTAINER

The present invention relates to a cleaning tool, and more particularly, to a cleaning tool capable of effectively removing various types of contamination generated on the surface of an object, for example, scale, dirt, mold, and the like.

In general, high-strength metal or ceramic materials are used for tableware such as bowls or cups, washbasins, toilet bowls, bathtubs, or tiles installed in bathrooms or toilets to improve ease of maintenance and appearance quality derived from the texture of the material. is produced by

These dishes or washbasins have the advantage that they are not easily corroded or damaged by the use of various detergents or cleaning tools because they are coated with a thin glaze made of glassy material to prevent moisture absorption or surface contamination. , Scale can easily form on the surface as moisture dries due to the nature of the environment of use, which is always exposed to moisture.

Scale is formed when trace minerals contained in tap water react with various pollutants or detergents, and deposits are deposited on the surface of dishes or washbasins, and cannot be easily removed with general detergents and washing tools. It is removed using a tool such as a scraper.

The scraper is configured to be equipped with a blade made of a plastic or metal material, and a user applies pressure to the blade to scrape foreign substances such as scale through the sharp edge of the blade. It consists of a scraper body with blades formed like an arc, and a handle connected to the body.

Since the components that make up the scale are not easily decomposed with general detergents, it is difficult to remove the scale generated on the surface of dishes or washbasins with a conventional scraper. In addition, if scale is removed using a plastic or metal scraper, the glaze of the finished surface layer made of ceramic is removed together, and fine grooves are generated on the surface of dishes or washbasins. There was a problem that scale easily gets stuck and the appearance quality is greatly deteriorated.

And in order to clearly explain the present invention in the drawings, parts irrelevant to the description are omitted, and similar reference numerals are attached to similar parts throughout the specification.

Throughout the specification, when a part is "connected" with another part, this includes not only the case where it is "directly connected" but also the case where it is "indirectly connected" with another member interposed therebetween. . In addition, when a part "includes" a certain component, this means that other components may be further provided without excluding other components unless otherwise stated.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of a cleaning tool according to an embodiment of the present invention, and FIG. 2 is a schematic diagram of a cross-section of a scraper according to an embodiment of the present invention.

1 and 2 , a cleaning tool according to an aspect of the present invention includes a scraper 100; a detergent container 200 extending from the scraper 100; and a detergent outlet 300 provided at one end of the detergent container 200, wherein the surface of at least one of the scraper 100 and the detergent container 200 may include an unevenness 140 .

The scraper 100 can remove the contamination generated in the cleaning area by contacting the cleaning area, and the unevenness 140 included in the surface of the scraper 100 not only increases the contact surface with the cleaning area but also the cleaning area. The force required to peel the contamination from the site is distributed substantially uniformly on the contact surface, allowing the user to more easily and effectively remove the contamination.

The detergent container 200 may be formed extending from the scraper 100 , and accordingly, the scraper 100 and the detergent container 200 may be integrally formed. Specifically, the scraper 100 and the detergent container 200 may be made of the same and/or homogeneous material and/or may be interconnected by a method such as bonding, sealing, or bending without any gap therebetween. . In addition, the surface of the detergent container 200 may include irregularities 140 formed in a predetermined pattern, and the irregularities 140 included in the surface of the detergent container 200 increase the contact surface with the washing part. In addition, the force required to peel the contamination from the cleaning site is substantially uniformly distributed on the contact surface so that the user can remove the contamination more easily and effectively.

In particular, when both the surface of the scraper 100 and the surface of the detergent container 200 include the irregularities 140 , substantially the entire area of the cleaning tool is capable of removing contamination generated in the cleaning area. When the irregularities 140 included in some areas of the surface of the scraper 100 and the detergent container 200 are worn and the cleaning power is reduced, the irregularities 140 included in other areas are removed. Because it can be washed by using it, the durability and lifespan of the cleaning tool can be extended.

3 is a schematic diagram of a method of manufacturing a scraper according to an embodiment of the present invention. Referring to FIG. 3 , the scraper 100 is a roll, stamp, or similar member having a pattern corresponding to the irregularities included on the surface of the other end of the detergent container 200, specifically, the detergent container ( 200) may be formed by pressing the other end of the sidewall, and if necessary, the member and/or the sidewall of the detergent container may be heated during such pressing. As used herein, the term “the other end of the detergent container” refers to an end of the detergent container 200 excluding the portion to which the detergent outlet 300 is coupled.

At least one of the scraper 100 and the detergent container 200 and the unevenness 140 may be integrally formed. Specifically, at least one of the scraper 100 and the detergent container 200, and the unevenness 140 may be made of the same and/or homogeneous material, and/or adhesive, sealing, They can be interconnected in such a way as by bending.

In addition, the unevenness 140 may be formed by pressing the scraper 100 and/or the detergent container 200 with a roll having a corresponding pattern, a stamp, or a member similar thereto, and if necessary, When pressing, the member and/or the scraper 100 and/or the detergent container 200 may be heated.

In addition, the scraper 100, the detergent container 200, and the unevenness 140 may be integrally formed, which includes a roll having a pattern corresponding to the unevenness to be formed on the surface of the scraper 100, a stamp, Alternatively, it may be implemented by a single process of pressing the other end of the detergent container 200, specifically, the other end of the side wall of the detergent container 200 with a similar member.

A thin layer of glaze made of glassy material is applied to the surface of metal or ceramic tableware or washbasin to prevent moisture absorption or surface contamination, and to improve the appearance quality. When using a scraper or blade to remove scale from ceramic dishes or washbasins, the sharp edge of the blade can easily damage the glaze surface layer, and friction occurs in the contact area with the blade, so it takes a lot of force to use the cleaning tool. As the blade does not completely adhere to the surface of the tableware or washbasin, scale cannot be easily removed. In contrast, the scraper 100 and the irregularities 140 formed integrally therewith may be in close contact with and in contact with the surface of the object to be cleaned to remove scale.

In addition, in the case of the cleaning tool, a detergent can be applied as needed while using a single cleaning tool, and various contamination generated on the surface of the object, for example, scale, by allowing the container in which the detergent is loaded to act as a handle , dirt, mold, etc. can be effectively removed.

2 and 3 , the sidewall of the detergent container may be made of a moisture impermeable material, and the scraper seals the other end of the detergent container through the laminated structure of the moisture impermeable material to which the sidewall is heat-pressed. can do.

The side wall 200 of the detergent container may be made of a moisture-permeable material, and as described above, the other end of the side wall 200 of the detergent container is heat-pressed to seal the other end of the detergent container. ) may also be made of a non-moisture-permeable material. As used herein, the term "moisture impermeability" refers to a property that does not substantially pass or permeate water, moisture, and moisture, and the moisture impermeable material may be non-porous and/or porous. When the moisture-permeable material is porous, the minimum size of the pores may be smaller than the minimum size of water, moisture, and moisture droplets generated during washing and cleaning. In addition, the moisture impermeable material may be a soft material having flexibility, and the scraper 100 and the detergent container 100 made of the moisture impermeable material may also have soft properties.

For example, the sidewall 200 of the detergent container is made of a plastic barrier laminate (PBL) material including a core layer containing ethylene vinyl alcohol, and a skin layer formed on at least one surface of the core layer and containing polyethylene. can be done In addition, the sidewall 200 of the detergent container may be made of an aluminum barrier laminate (ABL) material in which an aluminum film is interposed between the core layer and the skin layer, or replaced with the core layer and/or the skin layer. .

The PBL and/or ABL is a soft material and has strong corrosion resistance so that when removing scale using the cleaning tool, mineral components or various contaminants included in scale are not easily transferred or adhered to the surface of the scraper 100. do. The PBL and/or ABL are mainly used in containers such as toothpaste or cosmetics, and since the container discarded after the toothpaste or cosmetics is exhausted can be reused as it is, or it can be reused after appropriate post-treatment, it is not only eco-friendly but also of cleaning tools The manufacturing cost can be reduced.

The scraper 100 has a bilayer structure of the moisture impermeable material to which the sidewall 200 of the detergent container is heat-compressed, preferably, the first moisture impermeable layer 110 and the second moisture impermeable layer 120 . ) seals the other end of the detergent container 200 through the double-layer structure combined at the bonding surface 130, and at the same time, has mechanical properties such as strength and hardness necessary to remove scale, dirt, mold, etc. can be obtained

The scraper 100 having a double-layer structure made of the PBL and/or ABL can reduce the frictional force with the object to be cleaned, and has a hard surface and has a property of being easily deformed in the direction to which the force is applied, so that the user You can easily remove the scale created on the surface by attaching it to a curved surface such as a tableware or washbasin using a cleaning tool without much effort. In addition, the scraper 100 can prevent the surface of the object to be cleaned from being damaged, thereby effectively preventing the regeneration of scale on the damaged surface after cleaning.

The scraper 100 may have a thickness of 0.1 to 10 mm. The thickness of the scraper 100 may be changed according to, for example, the number of core layers and/or skin layers constituting the PBL. If the thickness of the scraper 100 is less than 0.1 mm, mechanical properties such as strength and hardness at a level necessary to remove scale, dirt, mold, etc. may not be secured, and durability may be reduced, and if it exceeds 10 mm, flexibility , the feeling of use, compatibility with detergents, and thus cleaning power may be reduced.

4 is a schematic view of the surface of a scraper according to an embodiment of the present invention as viewed from A or B of FIG. 1 , and FIG. 5 is a schematic view of a pattern (plan view) of irregularities according to an embodiment of the present invention.

4 and 5 , the unevenness 140 may include two or more protrusions 141 formed in a predetermined pattern, and the two or more protrusions may be spaced apart by a first interval 142 of 0.1 to 10 mm. .

The first gap 142 is a space between adjacent protrusions among the two or more protrusions 141 included in the unevenness 140 , and/or is adjacent to each other among two or more protrusions included in the second protrusion 151 to be described later. It means the distance between the projections. If the first gap 142 is less than 0.1 mm, it is not possible to secure the minimum surface roughness required to remove scale, and the resistance by water on the surface of the object to be washed is increased, so that scale cannot be effectively removed. Rather, there is a problem in that molding is difficult to provide a gap between the projections. On the other hand, if the first gap 142 is greater than 10 mm, the number of protrusions per unit area and the resulting surface area of the protrusions are small, so that scale cannot be effectively removed.

A cross-sectional area of a lower end of the protrusion may be greater than a cross-sectional area of the upper end. For example, the upper end of the protrusion may be round-treated (FIG. 4(b)) or may be molded into a needle shape (FIG. 4(c)), and may have a combined shape, but is not limited thereto. . When the cross-sectional area of the lower end of the protrusion 141 is larger than the cross-sectional area of the upper end, the lower end of the protrusion 141 provides support and fixing force during washing, while the middle and upper ends of the protrusion 141 provide flexibility and cleaning power accordingly. can provide

6 is a schematic diagram of the surface of a scraper according to another embodiment of the present invention as viewed from A or B of FIG. .

Referring to FIG. 6 , the unevenness 140 includes a first protrusion 141 and a second protrusion 151 , and the first and second protrusions are spaced apart by a second interval 160 of 0.1 to 200 mm, and , the second gap 160 may be formed in a direction different from that of the first gap 142 , preferably in a vertical direction.

The first and second protrusions 141 and 151 may be spaced apart from each other by a second interval 160 of 0.1 to 200 mm. The second gap 160 may be defined as a thickness of a dividing line dividing the first protrusion 141 and the second protrusion 151 adjacent thereto in a plan view of the irregularities 140 .

The size of the second gap 160 may be adjusted in the range of 0.1 to 200 mm depending on the size of the scraper 110 according to the application target of the cleaning tool, preferably, 0.1 to 100 mm, more preferably , may be 0.1 to 50 mm. If the second gap 160 is less than 0.1 mm, it is not possible to secure the minimum surface roughness required to remove scale, and the resistance by water on the surface of the object to be washed is increased, so that scale cannot be effectively removed. Rather, there is a problem in that molding is difficult to provide a gap between the projections. On the other hand, when the second gap 160 is greater than 200 mm, the number of protrusions per unit area and the resulting surface area of the protrusions become small, so that scale cannot be effectively removed.

Referring to FIG. 7 , the first protrusion 141 and the second protrusion 151 may have the same pattern as each other, or may have different patterns if necessary. In addition, the protrusions included in the first protrusion 141 may be formed in the same pattern, or may be formed in different patterns, if necessary. In addition, the protrusions included in the second protrusion part 151 may have the same pattern or, if necessary, may have different patterns.

The first and second protrusions 141 and 151 are spaced apart by the second gap 160 and, if necessary, may be formed to cross one or more times, and FIG. 4 shows these first and second protrusions ( 141 and 151) indicate a pattern that is crossed twice. In FIG. 4, the first protrusion 141 has a plurality of protrusions having a straight line pattern arranged in parallel, and the second protrusion 151 has the same pattern as the first protrusion 141 (Fig. 7(a)). )), a plurality of protrusions having a straight pattern displaced from the first protrusion 141 are arranged in parallel (Fig. 7(b)), or a plurality of protrusions having a curved pattern are arranged in parallel (Fig. 7(c)), It may be formed of a plurality of protrusions having a concentric circle pattern (FIG. 7(d)).

Although not shown, the second protrusion 151 has a plurality of protrusions having a straight pattern arranged in parallel, and the first protrusion 141 has the same pattern as the second protrusion 151 or the second protrusion A plurality of protrusions having a straight pattern displaced from (151) may be arranged in parallel, a plurality of protrusions having a curved pattern may be arranged in parallel, or a plurality of protrusions having a concentric circle pattern may be formed.

8 is a schematic diagram of an uneven pattern (plan view) according to another embodiment of the present invention. Referring to FIG. 8 , the unevenness may include two or more linear protrusions formed in different directions. As used herein, the term “linear protrusion” refers to a protrusion having a linear pattern made of a straight line, a curved line, or a combination thereof, and the linear pattern may be continuous or discontinuous.

In general, since these irregularities are formed in only one direction in a cleaning tool, it is inconvenient to use the cleaning tool because the cleaning tool has no choice but to be applied in a specific direction when removing scale, that is, the application direction of the cleaning tool is limited by the uneven direction. There was a problem. In contrast, since the unevenness 140 includes two or more linear protrusions formed in different directions, it can be conveniently used without restrictions according to the direction, and scale can be effectively removed.

The linear protrusion may be formed of two or more linear protrusions formed in different directions. As used herein, the term "different directions" refers to (1) when two or more straight projections are not parallel to each other (FIGS. 8(a) and 8(b)), (2) when one or more straight projections have a zigzag shape It can be interpreted as including cases (FIG. 8(c)) and (3) cases in which tangents at any two points of one or more curved projections are not parallel to each other (FIG. 8(d)).

The height of the unevenness 140 , specifically, the height of the projections 141 and 151 included in the unevenness 140 may be 0.1 to 10 mm. The height of the irregularities 140 may be changed according to, for example, the number of core layers and/or skin layers constituting the PBL. If the height of the irregularities 140 is less than 0.1 mm, scale cannot be effectively removed, and if it exceeds 10 mm, the feeling of use may be reduced when the scraper 100 is directly held and used by hand.

Meanwhile, at least one of the sidewall and the scraper of the detergent container may include an antibacterial agent, a perfume, or a combination thereof.

The antibacterial agent and/or the fragrance agent may be suitably dispersed on the sidewall of the detergent container and/or inside the scraper, or may be suitably applied to the sidewall of the detergent container and/or the surface of the scraper.

In addition, the antibacterial agent and/or the perfume is mixed with a predetermined resin, for example, polyethylene terephthalate (PET) to prepare a film form, and then this film is attached to the sidewall of the detergent container and/or the surface of the scraper can do it 9 is a schematic diagram of a cross-section of a side wall of a detergent container according to an embodiment of the present invention. Referring to FIG. 9 , the sidewall 200 of the detergent container may include a moisture-permeable layer 210 and a functional layer 300 , and the film prepared as described above may be applied to the functional layer 300 . .

The antibacterial agent may be one selected from the group consisting of inorganic antibacterial agents, organic antibacterial agents, metal antibacterial agents, ammonium salt antibacterial agents, guanidine antibacterial agents, copper compound antibacterial agents, sustained release polymer antibacterial agents, natural antibacterial agents, and combinations of two or more thereof. It is not limited.

The organic antibacterial agent is mainly in a liquid state, and has the advantage of exhibiting an immediate antibacterial effect by preventing the formation of a colony of bacteria rather than sterilization, so it can be added to products requiring antibacterial activity in a short time. The durability of antibacterial activity is temporary, and the organic antibacterial agent can be thermally decomposed under high temperature conditions, so it cannot be applied.In addition, it can generate resistant bacteria and threaten human safety because of its high acute toxicity. may be one selected from the group consisting of thiabendazole, isothiazole, zinc pyrithione, imidazole, carbendazole, tricholonic acid, and a combination of two or more thereof, but is not limited thereto.

The natural antibacterial agent is a substance frequently encountered in daily life, and it induces user friendliness and has the best human safety. Efficiency may be reduced. The type of the natural antimicrobial agent may be one selected from the group consisting of mulberry bark, grapefruit seed, bamboo, fig, mugwort, aloe, ginseng, phytoncide, green tea, and a combination of two or more thereof, but is not limited thereto.

The inorganic antibacterial agent has a low initial antibacterial activity, but unlike the organic antibacterial agent, human safety and thermal stability are high, resistant bacteria do not occur, and antibacterial durability is almost semi-permanent, so its use range can be broadly applied compared to the organic antibacterial agent. The inorganic antibacterial agent may be one selected from the group consisting of zeolite, calcium phosphate, zirconium phosphate and a combination of two or more thereof, and preferably, silver (Ag), zinc ( Zn), copper (Cu), manganese (Mn), such as a metal ion having excellent antibacterial activity may be substituted. Since the inorganic antimicrobial agent has a three-dimensional skeleton structure with fine pores, it has a large specific surface area and excellent heat resistance. In particular, the zeolite-based antibacterial agent is the most widely used because of the high metal ion support. In addition, the zeolite-based antibacterial agent does not have a discoloration problem compared to other antibacterial agents, and has advantages such as high antibacterial power, high safety, and low particle hardness. On the other hand, the calcium phosphate-based antibacterial agent has a disadvantage in that the concentration of the metal ion to be substituted is low, and thus the antibacterial activity is lower than the concentration of the metal ion to be substituted is low compared to the zeolite-based antibacterial agent.

The metal ion may be selected as needed, but preferably silver (Ag). The silver (Ag) has excellent antibacterial activity, is non-toxic and non-irritating to the human body, and has excellent chemical durability and heat resistance. In addition, since silver ions can be released over a long period of time, antibacterial durability is excellent.

The fragrance may be a natural fragrance, preferably, a vegetable oil. The vegetable oil is a volatile oily substance that can be obtained from flowers, buds, fruits, leaves, branches, stems, roots and natural resins of aromatic plants, and is lighter than water, and is called essential oil and is distinguished from oils and fats. In general, the vegetable oil may be prepared by heating by adding water in a weight ratio of 1:1 to 100 to the extraction part of the plant, or by passing pressurized steam to drain the essential oil together with the steam.

As a method for producing such vegetable oil, steam distillation method in which essential oil is discharged at a temperature lower than the actual boiling point, compression method in which the skin is pressed, adsorption method in which it is absorbed in a nonvolatile solvent such as fat, and a volatile solvent is used. A solvent extraction method for extracting a fragrance component, a leaching method for collecting a sap that is leached by making a wound on the stem or root of a plant, and a supercritical gas extraction method may be mentioned, but are not limited thereto. The vegetable oil emits a unique fragrance according to each component, and has excellent sterilization, disinfection, antibacterial and antiviral effects compared to artificial synthetic components. The fragrance may be one selected from the group consisting of pine, jasmin, lemon, lavender, mint, and a combination of two or more thereof, but is not limited thereto.

On the other hand, the detergent carried in the detergent container 200 through the detergent outlet 300 provided at one end of the detergent container 200 can be applied to the washing area if necessary. The detergent discharge port 300 may be formed integrally with the detergent container 200, and, if necessary, may further include a separate discharge means such as a cap having a spray or a truncated cone-shaped cap.
