Description

NATURAL CLEANING TOOL

The present invention relates to a natural washing utensil, and more particularly, to a natural washing utensil which is made of a natural material, minimizes skin irritation, and has excellent washing power and durability.

In general, a cleaning tool refers to a scrubber used to clean a tableware, a towel or a sponge used for wiping off sweat or foreign matter remaining on the skin of a human body with soap or body washes with water.

In particular, chemical cleaning sponge made of chemical fiber has been used as a conventional cleaning tool used for cleaning the skin of human body, and there has been a problem that side effects are caused on skin sensitive to external stimuli during use.

Recently, as disclosed in Patent Document 1, the use of natural sponge made of natural materials is increasing to reduce skin irritation. However, the natural sponge disclosed in Patent Document 1 is only made of soft konjac material and is hypoallergenic, which is suitable for delicate type skin or face washing, but the user can not obtain a satisfactory cleaning effect for other skin type or washing site. Therefore, the user has to purchase and use separate cleaning tools corresponding to the cleaning area or cleaning purpose. In addition, the natural sponge is less durable than a chemical sponge and has a short period of use.

Patent Document 2 discloses a method of manufacturing a honeycomb structure, which comprises the steps of filling a part of the internal space of a forming mold having a space therein with natural scrubbing powder, adding a konjac powder to the mixing solution, stirring and mixing to prepare a raw material, A forming step of pouring the raw material into the remaining space inside the forming mold to form a shape in which the natural wool and the raw material adhere closely to each other, a ripening step of ripening the raw material put in the forming mold, a step of heating the aged raw material by steam heating A step of heating the sponge to form a sponge in close contact with the natural scrubber, and a step of cooling, freezing and thawing the sponge adhered to the natural scrubber formed through the steam heating step. In the first embodiment, Adding a natural woolen piece of the natural woolen piece, stirring and mixing to prepare a raw material, pouring the raw material into a mold A steam heating step of forming a sponge shape adhered to a natural scrubber by steam heating the aged raw material, and a steam heating step of heating the aged raw material by steam heating to form a sponge- A second embodiment including a step of cooling, freezing, and defrosting a sponge adhered to a natural scrubber is disclosed.

However, in the first embodiment of the patent document 2, the natural wastepaper is first filled in the mold, and then the remaining space is filled with a raw material mixed with konjac powder. Since only the natural wool having a rough property is exposed to the outside, the rough natural material is repeatedly applied to the skin when the user uses the natural wool wool face, which may cause skin irritation and side effects.

In the second embodiment of the patent document 2, the raw material in which the konnyaku powder and the plurality of natural woolen fragments are mixed together at the beginning is filled in the molding frame at one time. When natural konjac powder and natural scrubbing powder are molded together in the molding frame, the shape of the sponge structure is not formed well and the quality of the cleaning implement is deteriorated. Only the cleaning surface type having one property is present because the configuration of both surfaces of the cleaning implement is the same and the pieces of the natural scrubbing surface are exposed to the surface less than the surface of the base layer coated with the sponge of natural wreath, Is not effective in selecting a suitable site according to the skin type or skin area There is a problem of decrease.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The natural washing utensil according to the present invention comprises a substrate layer composed mainly of natural konjac and a coating layer formed by dispersing a plurality of natural wool scraps or natural cellulose powder on the surface of one surface of the substrate layer, By integrating the natural materials into one cleaning tool, the user can select and use a suitable surface on both sides depending on his / her skin type, washing area and cleaning purpose, so that a satisfactory cleaning effect can be obtained and another separate cleaning tool There is no need to purchase, which reduces the price burden, minimizes skin irritation and side effects, enhances durability and increases product life and quality.

Referring to FIGS. 1 and 2, the natural cleaning implement 1 of the present invention comprises a base layer 2 and a coating layer 3.

The base layer (2) is made of a natural konjac as a main component and has a sponge structure of a network structure. The shape of the base layer (2) is not particularly limited and various shapes such as a rectangular parallelepiped, a cube, a cylinder, and a spherical shape are possible.

Natural konjac is a perennial plant belonging to the Taran family. It is planted in spring and harvested in late autumn. It is planted again in the next spring for 2 ~ 3 years to be used as a raw material. After thinly sliced, it is dried to remove starch and gluco mannan) as a main ingredient. Such natural konjac has been mainly used in foods such as fish products such as fish paste, crab meat, ham, frozen food, and noodles.

The nature of natural konjac is that it can absorb water by about 15 to 40 times, swell when absorbed, become a colloid state, so it has excellent water retention, and has an excellent moisture retention property to prevent surface drying.

In addition, natural konjac is a soft material and hypoallergenic which is used by users with sensitive skin types to prevent skin irritation and side effects, to provide a pleasant washing sensation, and to enhance the massage effect by the unique sponge structure of reticular tissue And increases the cleaning effect of fine pollutants. In particular, the base layer 2, which is a main constituent of natural konjac, is composed of a dense, fine mesh, and is smooth and soft.

The coating layer 3 is formed by applying a coating material having a roughness larger than that of the natural konjac to the surface of one side of both surfaces of the base layer 2, as shown in FIG. 1, or a plurality of natural wool shavings, So that a part of the surface of the substrate layer 2 is exposed to the outside. A plurality of natural wool shavings or natural cellulose powders are preferably applied uniformly over the entire surface of the base layer 2, but the applied layer 3 may be scattered over the entire area of the base layer 2 And can be scattered and applied over a part of the base layer 2, and the area where the coating layer 3 is formed is not particularly limited.

Natural scrubbing refers to the dry sponge tissue part of the fruit of the loofah cucumber. The name Spoon-Oi is sponge-gourd or vegetable sponge in English. Natural sponge has sponge-like properties, as the English name suggests, due to the natural woolen netting of the fibers.

Since the network of the natural wool fabric forming the coating layer 3 is not so fine or denser than the network of the base layer 2 composed mainly of natural konjac, the feel is relatively rough, It is suitable for use in cleaning skin areas less susceptible to external stimuli.

The natural scrubbing brush is applied to the surface of one of the two sides of the base layer 2 in the form of a plurality of pieces in order to enhance the cleaning ability to the skin area less susceptible to external stimuli. In this case, the size of the natural woolen piece is preferably 1 to 10 mm. When the size of the natural woolen piece is smaller than 1 mm, when the natural woolen piece is applied to the surface of the base layer 2, the roughness of the surface is insufficient and the detergency is lowered when used on the body part such as the trunk, arms and legs, , Whereas when the size of the natural worn-out piece is larger than 10 mm, the skin cleansing power and exfoliation effect are increased, but skin irritation and side effects may occur due to repeated use, and the applied layer (3) Life and quality may be deteriorated.

Natural cellulose is the main component of the cell wall of higher plants and is the substance with the highest molecular weight among polysaccharides and is also called fibrin. The molecules of natural cellulose are formed by dehydration polymerization of many glucose and are connected like a chain. Since water molecules can enter between the hydrogen bonds of natural cellulose and hydrogen bonds can be newly formed, the material made of natural cellulose is a large amount of water It is not only excellent in water absorbability, but also has excellent tensile strength and excellent wear resistance and durability when applied to the surface of the base layer 2 as shown in Table 1 below. Life and quality are greatly increased. In addition, since the natural waters include lignin of a rigid material such as an organic polymer, wear resistance and durability are increased to some extent even when a natural wool scrap is applied to the surface of the base layer 2 and used.

[Table 1]

Natural cellulosic is less than the natural konjac-based sponge, and has a feeling of roughness and feeling of roughness that is pulp-like. It is used for washing the body parts such as trunk, arms and legs which are less sensitive to skin exfoliation or external stimuli Suitable.

The natural cellulose is applied to the surface of one of the two sides of the base layer 2 in powder form to enhance the cleaning power for skin areas less susceptible to external stimuli. In this case, the particle size of the natural cellulose powder is preferably 100 to 1,000 mu m. When the particle size of the natural cellulose powder is less than 100 탆, when the natural cellulose powder is applied to the surface of the base layer 2, the surface roughness is insufficient and the washing power is lowered when used on the body parts such as the trunk, arms and legs, On the other hand, when the particle size of the natural cellulose powder is larger than 1,000 탆, the skin cleansing power and exfoliation effect are increased, but skin irritation and side effects may occur due to repeated use, and the application layer 3 The life and quality of the product may be deteriorated, and it may be difficult to smoothly pass through the vats used in powder application, so that the uniform application may not be performed and the cleaning effect and merchantability may be deteriorated.

The natural cellulosic powder can be applied in various kinds by the hole size of the porous plate. The natural cellulosus has a property of self-aggregating with cellulose, so that the powder particles are agglomerated in the hole size by the vibrating vibration and applied to the surface of the base layer 2 in an embossed form to improve the cleaning effect and the commerciality.

It is preferable that the application area ratio of the coating layer 3 is 50 to 90% per unit area (cm 2) of the surface of the base layer 2. When the applied area ratio is less than 50%, the coating layer 3 occupies a small proportion, and when used in a skin area, the detergency, exfoliation and skin massage effects may be deteriorated. When the applied area ratio exceeds 90% The area of the soft base layer exposed to the outside is small, and when the user uses the surface coated with the application layer 3, only rough materials are repeatedly applied to the skin, so that skin irritation and side effects may occur. Therefore, when the base layer 2 and the coating layer 3 are appropriately formed at the above-mentioned coating area ratio over the whole surface of the base layer 2, the best cleaning effect on the skin and the touch feeling on the skin are reduced .

In addition, the natural washing utensil (1) according to the present invention comprises a substrate layer composed mainly of natural konjac, and a coating layer formed by dispersing a plurality of natural wool scraps or natural cellulose powder on the surface of one surface of the substrate layer, (3) to the base layer (2) by integrating the natural materials having different properties into one cleaning tool, thereby fixing the fibers of the portion where the coating layer (3) comes into contact with the base layer (2) So that the lifetime can be prolonged.

FIG. 3 is a flow chart of a method for manufacturing a natural washing utensil according to the present invention. Referring to FIG. 3, a method for manufacturing a natural washing utensil according to the present invention will be described in detail.

A method of manufacturing a natural washing utensil according to the present invention includes: a raw material manufacturing step (S101) of adding a natural konjac powder to a blending solution containing water and stirring and mixing to produce a gel-like raw material; A forming step (S102) of filling a raw material into a forming mold and filling the applied raw material on a surface exposed to the outside of the raw material in the forming mold (S102); An aging step (S103) of aging the raw material coated with the coating material by being put in a molding mold; A steam heating step (S104) in which the aged raw material is placed in a steam oven and steam heated to form a sponge shape; A cooling step (S105) of cooling the sponge formed through the steam heating at room temperature; A first freezing step (S106) in which the cooled sponge is quenched in a freezer and frozen; A primary defrosting step (S107) of defrosting the frozen primary sponge; A second freezing step (S108) of freezing the sponge firstly thawed in the freezer; A second defrosting step (S109) of defrosting the second frozen sponge; And a hot-air drying step (S110) of hot-air drying the sponge that is secondarily defrosted.

① raw material manufacturing step (S101)

In the raw material manufacturing step (S101), the compounding solution is a compounding solution usually used for sponge production, and is formed by mixing water, neutralizing agent, foaming agent, emulsifier, and the like. The content of the natural konjac powder to be added to the blend solution in the raw material production step (S101) is preferably 1 part by weight of the natural konjac powder compared to 12 parts by weight of the blend solution. Such a mixing ratio is such that when the sponge is formed, So that the sponge shape can be smoothly formed by the compounding solution. In this case, the natural konjac powder is melted and gelated. Accordingly, when the compounding solution and the natural konjac powder are mixed and stirred with a stirrer, bubbles are formed through the steam heating step (S104), which will be described later, so that the shape of the sponge can be achieved.

(2) Forming step (S102)

In the molding step (S102), the raw material produced through the raw material manufacturing step (S101) is poured into a molding mold to form a desired shape. At this time, the raw material in the form of gel prepared through the step of manufacturing the raw material (S101) is injected into a mold, filled with a plurality of natural wool particles or natural cellulose powder, And the coating material is firstly adhered on the surface of the raw material due to the viscosity of the gel-like raw material, and the bonding of the different materials proceeds secondarily by hydrogen bonding by the chemical reaction.

At this time, the binding force depends on the time of applying the coating material such as a plurality of natural wool scraps or natural cellulose powder onto the gel-like raw material mixed with the natural konjac powder and the blending solution injected into the molding die. In general, the proper mixing ratio of natural konjac powder with high water solubility depends on the viscosity of the sponge. The natural konjac powder is agitated with the compounding solution at a proper ratio and then absorbed water for 3 to 4 hours to expand. On the surface of natural konjac which has been completely absorbed and expanded, the moisture content is decreased, so that the primary bonding due to viscosity is weakened when applying the coating, and the bonding force is lowered. Therefore, it is preferable that the coating material is applied on the raw material in the range of 0.5 to 3 hours after performing the raw material preparation step (S101) before the natural konjac powder completely absorbs and expands the water. If the coating material is applied onto the raw material in less than 0.5 hour, the coating material can penetrate into the raw material and be mixed.

On the other hand, the method of applying a plurality of natural wool scraps or the natural cellulose powder is not particularly limited, but it is preferable to apply a predetermined amount of the coating material on the porous plate as a coating and apply the coating in a vibration mode.

(3) Aging step (S103)

The aging step (S103) is carried out in order to agglomerate the raw material coated with the coating material by being contained in the forming mold so that the raw material can be completely expanded and solidified according to the shape of the forming mold.

(4) Steam heating step (S104)

The steam heating step (S104) is a step of forming a sponge shape by forming bubbles in the raw material through steam heating of the raw material after aging (S103). At this time, the coating material applied on the raw material is heated It is possible to form a coating layer perfectly bonded to a raw material containing natural konjac as a main component without using an adhesive which can cause a strong tertiary hydrogen bonding and have a detrimental effect on the human body.

(5) Cooling step (S105)

In the cooling step (S105), the sponge formed through the steam heating step (S104) is gradually cooled at a normal temperature before quenching.

(6) First freezing step (S106)

In the first freezing step (S106), the sponge that has undergone the cooling step (S105) is rapidly quenched from the freezer to a freezing temperature and freezed. As a result, the surface of the sponge is quickly frozen to form the main ingredient of the natural konjac It is intended to make glucomannan more natural and stronger in the fibers of the natural fiber and the application.

⑦ First thawing step (S107)

The primary defrosting step (S107) is a process for defrosting the frozen sponge through the first freezing step (S106) to remove water contained in the sponge and the residual compounding solution additive.

(8) Secondary freezing step (S108)

The second freezing step (S108) is a freezing process in which the sponge that has undergone the first thawing step (S107) is frozen again at a freezing temperature in the freezer. By repeating this freezing process, glucomannan, And the fiber of the application product can be made stronger and stronger, and the life of the product can be prolonged.

(9) Secondary thawing step (S109)

The second defrosting step (S109) is a process of defrosting the frozen sponge through the second freezing step (S108) to completely remove water, compound solution additives and impurities remaining in the sponge.

(10) Hot air drying step (S110)

The hot air drying step (S110) is a hot air drying process for long-term storage of the sponge after the second thawing step (S109). Since the sponge contains natural konjac, natural wool or natural cellulose, To prevent the propagation of fungi or bacteria in the state.

As a result, the natural washing utensil 1 according to the present invention can be conveniently used in accordance with the user's general skin type, washing area or washing purpose by using one washing utensil, It is possible to obtain a satisfactory cleaning effect desired by the user and to minimize skin irritation and troubles due to natural materials, and it is also possible to use a soft natural konjac base layer and a somewhat rough coating layer on one side It is possible to reduce the skin irritation and side effects even more when the skin is applied to the skin. Therefore, it has excellent absorbency and cleaning power, has a function of exfoliating and enhances the durability so that the coating layer is not easily separated. .
