Description

  The present invention relates to a sheet-type skin cleaning tool in which a cleaning substrate sheet and a sheet-like cleaning agent as a cleaning agent are integrated by lamination and pressure bonding.

Various cleaning tools used at the time of showering or bathing have been used for a long time, and generally, different cleaning agents and soaps and bath towels are used. However, it was bulky and heavy and inconvenient, especially when trying to carry them to travel destinations.
In view of this, various devices have been proposed in which a cleaning tool and a skin cleaning agent are integrated and are easy to carry and easy to handle.
For example, a cleaning tool having a structure in which a polyurethane foam containing a solid soap is covered with a nylon fiber base material has been proposed in German Patent Publication No. 2121388 (Patent Document 1).

In order to achieve compactness, a disposable body cleaning tool in which a sponge sheet having a continuous pore structure is impregnated with a cleaning agent containing fatty acid soap has been proposed in, for example, US Pat. No. 4,397,754 (Patent Document 2). ing.
Further, JP-A-5-117699 (Patent Document 3) discloses a cleaning tool in which a cellulose sponge base material is coated with a surfactant having an HLB of 7 or more in a non-aqueous state.
As a technique similar to this, a technique of applying a cleaning agent on a porous substrate such as a sponge by a coating method or a spray method is disclosed in US Patent Publication No. 2005/0158368 (Patent Document 4).
On the other hand, for the purpose of maintaining adhesiveness in a wet state, an integrated cleaning tool in which a water-shielding film is sandwiched between a synthetic sponge and a soap bar and adhered to each other with a water-insoluble adhesive is disclosed in British Patent Publication No. 9777156. (Patent Document 5).

German Publication No. 2121388 U.S. Pat. No. 4,397,754 Japanese Patent Laid-Open No. 5-117699 US Patent Publication No. 2005/0158368 British Patent Publication No. 9777156

As described above, according to the technique of Patent Document 1, the manufacturing process is complicated due to the large number of members constituting the cleaning tool, and is not suitable for production in an integrated process.
When used, bulk products are not very easy to handle, and in order to dispose of used cleaning tools, the remaining soap treatment is difficult and half-finished. There was also a concern that mold would be generated on the bag depending on the storage state.
Next, according to the technique of Patent Document 2, a sponge sheet base material having a continuous pore structure is compressed, and an attempt is made to impregnate a cleaning agent comprising a fatty acid soap and a polyethylene oxide alkyl ether type nonionic surfactant in a molten state. There is a feature in the point to do. However, it is difficult to impregnate a substrate with a detergent composition having a high viscosity, and heating and cooling are required, which complicates the process and has a difficulty in cost.
Next, according to the technique of Patent Document 3, the surface of the compressed cellulose foam substrate is coated with a liquid detergent, but a very small amount of detergent is used to prevent dripping and spillage during coating. However, it could only be applied and was unsuitable for producing a sufficient cleaning effect during use.

According to the technique of Patent Document 4, a technique for spraying or applying a liquid detergent onto the surface of a porous substrate is disclosed, but the same problems as described above existed. In the case of spraying, there is also a problem that loss is large.
Further, according to the technique of Patent Document 5, a manufacturing process is performed in which a barrier film is adhered onto a sponge block and solid soap is adhered onto the sponge block with a water-insoluble adhesive. However, in order to bond soap, it is difficult to select a suitable adhesive. Moreover, the cleaning tool obtained by this method is hard, has a poor feeling of use, and does not have sufficient foaming properties.
Also, according to this technology, the soap and sponge are separated by a water-impermeable barrier film, so in use, after applying soap to the skin, the cleaning tool is inverted and the body on the sponge surface. When the foam disappears, it is reversed again, and this operation must be repeated, which is very complicated. Further, there has been a problem that the cleaning tool is easily dropped on the floor during the reversing operation.

As described above, as a result of earnest research in view of the above-described problems, the present invention can be used to obtain a sufficient amount of soap for washing the skin surface with an elastic base material by a simple process without using an adhesive. It is an object of the present invention to provide a technology that can be integrated so that the original shape can be reliably maintained and can be continuously manufactured.
The surface to be used is flexible so that it can be reliably cleaned even on undulating parts such as the face, and it can be cleaned without having to change your hand or flip it during cleaning. It is an object to provide a cleaning tool having an excellent cleaning effect.
Furthermore, from the viewpoint of portability, another object is to provide a simple cleaning tool that can be packaged thinly and compactly and can be discarded as it is after use.

A first invention is a cleaning tool in which (a) a sheet-like cleaning agent having flexibility and (b) a water-absorbent sheet having compression elasticity in a wet state are laminated and bonded, The sheet-like cleaning agent is water-soluble, and has a structure in which one side of the sheet-like cleaning agent is dissolved and impregnated in the water-absorbent sheet and is adhered to one or both sides of the water-absorbent sheet It is a tool.
A second invention is a sheet-like skin cleaning tool, wherein the sheet-like cleaning agent contains a water-soluble polymer, a surfactant, a moisturizing agent and water.
A third invention is a sheet-like skin cleaning tool, wherein the dissolution rate of the sheet-like cleaning agent in water is in the range of 5 seconds to 90 seconds at 25 ° C.
A fourth invention is a sheet-like skin cleaning tool, wherein the sheet-like cleaning agent has a tensile elongation of 2% to 8%.
A fifth invention is a sheet-like skin cleaning tool, wherein the water-absorbent sheet is one or more sheets selected from a fiber sheet and a sponge sheet.
A sixth invention is a sheet-like skin cleaning tool, wherein the fiber sheet contains silk.
A seventh invention is a sheet-like skin cleaning device, wherein the sponge sheet is one or more sponge sheets selected from a cellulose sponge sheet and a synthetic resin sponge sheet.
The eighth invention is a sheet-like skin cleaning tool, wherein the water-absorbent sheet has a network structure on the side in contact with the sheet-like cleaning agent.
According to a ninth aspect of the present invention, there is provided a sheet-like skin cleaning tool, wherein character information, a pattern or a pattern is imparted to the surface of the sheet-like cleaning agent.

According to the present invention, soap and a porous material, which have been difficult without using an adhesive in the past, can be reliably obtained by using water as a medium without using a complicated process and without using a special adhesive. The skin cleaning sheet can be manufactured continuously. For this reason, process loss is significantly reduced and running cost can be suppressed. In addition, since the sheet-like cleaning agent can be stably bonded without cracking, cracking or cracking, it is possible to provide a cleaning tool with excellent appearance quality.
Since the sheet-like skin cleaning tool of the present invention is a thin sheet and has excellent flexibility, it is also effective for cleaning highly uneven parts such as the face. In addition, when wet, the soap quickly dissolves from the portion in contact with water, and the foaming effect is enhanced by the foaming effect of the water-absorbing substrate having compression elasticity, so that the cleaning effect is high.
Not only can it be used for cleaning predetermined parts of the body such as the face, hands, and neck, it can also be used for cleansing such as make-up removal.
Moreover, the sheet-like skin cleaning tool of the present invention is lightweight and not bulky, and is excellent in portability to a travel destination or the like.

The skin cleaning tool of this invention is demonstrated using figures.

5 and FIG. 6 have a part of the structure so as to facilitate understanding of the present invention, but in actuality, it is an entire laminated structure as in FIGS.
The skin cleaning tool of the present invention is basically a cleaning tool sheet provided with a sheet-like cleaning agent containing a plastic, water-soluble polymer, surfactant, moisturizing agent and moisture, and a water-absorbing sheet. As shown in FIG. 1, the sheet-like cleaning agent 1 having plasticity and a sponge sheet 2 of a water-absorbing sheet may be laminated, or the sheet-like cleaning agent 1 may absorb water as shown in FIG.

In the following examples, the material and structure of the sheet-like cleaning tool shown in FIGS. 1 to 4 will be described more specifically.

Moreover, the member which comprises the sheet-like skin cleaning tool of this invention is also demonstrated.
The sheet-like cleaning agent of the present invention is a sheet having flexibility and flexibility, preferably a sheet comprising a water-soluble polymer, a surfactant, a moisturizing agent, and water.
The water-soluble polymer is not particularly limited as long as it is water-soluble and forms a film-like film after drying.
For example, cellulose derivatives such as cellulose and cellulose ether (eg, methyl cellulose, hydroxyethyl methyl cellulose, hydroxypropyl methyl cellulose, hydroxy pyrrole cellulose, hydroxybutyl cellulose, carboxymethyl cellulose); polyvinyl alcohol; starch; pullulan; sodium hyaluronate; acetylated hyaluron Polysaccharides such as sodium acid; water-soluble collagen, sodium alginate, polyvinylpyrrolidone, sodium polyacrylate and the like. In particular, hydroxypropylmethylcellulose, starch and pullulan are suitable. In addition, the said water-soluble polymer may be used individually or may be used in combination of 2 or more type.

  Surfactants include fatty acid alkali salts, acylamino acid alkali salts, alkyl sulfate ester salts, polyoxyethylene alkyl ether salts, acyl sulfosuccinates, acyl taurine salts, acylmethyl taurine salts, monoalkyl phosphates, alkyl ether carboxylic acids Anionic activators such as salts, hydroxyalkyl ether carboxylates, amphoteric activators such as imidazoline amphoteric activators, betaine amphoteric activators, polyoxyethylene alkyl ethers, polyoxyethylene fatty acid esters, alkyl glucosides, maltitol hydroxy fatty acids Nonionic activators such as esters and polyglyceryl monolaurate, and cationic activators such as trimethylalkylammonium chloride. In particular, fatty acid alkali salts, imidazolinium-based amphoteric activators, betaine-based amphoteric activators, and hydroxy ether carboxylates are preferred. In addition, the said surfactant may be used individually or may be used in combination of 2 or more type.

Moisturizers include polyhydric alcohols such as glycerin, diglycerin, polyglycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, sugars such as sugar, trehalose, maltose, sorbitol, erythritol, xylitol, maltitol, etc. Examples thereof include sugar alcohols and amino acids. Particularly preferred are glycerin and diglycerin. In addition, the said humectant may be used individually or may be used in combination of 2 or more type.
Moreover, vegetable oils, such as coconut oil, rapeseed oil, coconut oil, and palm oil, can also be mix | blended for foaming promotion.
If necessary, skin care ingredients such as coenzyme Q10, lipoic acid, and flavonoids can be blended.
By blending the above components, it is possible to provide a high cleaning effect while reducing skin irritation.

Moreover, the thing of about 50 micrometers-200 micrometers can use preferably the thickness of this sheet-like cleaning agent. More preferably, it is about 50 μm to 150 μm. It is because it is rich in a flexibility and it can ensure the soap amount required for washing | cleaning as it is this range.
The sheet-like cleaning agent preferably contains a humectant and water in order to easily dissolve in water. The amount of water contained in the sheet-like cleaning agent is preferably in the range of 1 to 20% by weight. The dissolution rate in water is preferably 5 seconds or more and 90 seconds or less at 25 ° C., more preferably 10 seconds or more and 45 seconds or less. The dissolution rate is measured by the following method.
A square sample of size 6cm x 6cm and thickness 120μm is prepared, stirred at a constant speed in 500ml of 70ppm artificial hard water under the condition of 25 ° C, and the time required for complete dissolution is measured. Dissolution rate.

When blending and preparing so that the dissolution rate falls within this range, the surface of the water-absorbent sheet as the base material is moistened, and then the soap component dissolved and softened when the sheet-like detergent is pressure-bonded to this surface, It easily penetrates into the voids of the water-absorbent sheet, and is dried and fixed to develop an adhesive structure. In addition, the sheet-like cleaning agent can be bonded without being deformed or swollen.
The soap component in which a part of the sheet-like cleaning agent is dissolved and penetrates into the voids of the water-absorbent sheet is present in the voids even when dried, so that the adhesive structure is maintained. For this reason, it is particularly preferable to contain a water-soluble polymer such as hydroxypropylmethylcellulose or pullulan as a component that contributes to adhesion because the adhesion effect is further enhanced.
Furthermore, with such a structure, even if it is wet with water at the time of use, peeling does not occur at the adhesive interface, and the soap component dissolves quickly and is also absorbed inside the water absorbent sheet. Foaming effect due to the compression elasticity of the sheet tends to cause forming, and the cleaning effect is enhanced.

As the sheet-like cleaning agent used in the present invention, a flexible and flexible sheet material is used. The sheet-like detergent that can be preferably used has a breaking elongation of 2% to 8% by a tensile test method (tensile interval (grip interval) 30 mm, tensile speed 6 mm / min) under the conditions of a temperature of 20 ° C. and a humidity of 60% RH. It is preferable to use a material having a stress of about 1 to 4 MPa (1 to 4 N / mm ² ). When the tensile properties are within this range, handling is easy, lamination with the water-absorbent sheet and adhesion processing are easy, and process loss can be reduced.
In order to enhance the decorating property, the surface of the sheet-like detergent used in the present invention can be colored with a pigment or the like, or a spotted pattern can be imparted using a granule component or a scrub agent. In addition, an arbitrary pattern or information such as a pattern or a character can be given by a technique such as silk printing or screen printing. Moreover, unevenness | corrugation can also be provided by methods, such as embossing.

Next, the water absorbent sheet used in the present invention will be described. The water-absorbent sheet needs to have water absorption and water retention at least on the surface side to which the sheet-like cleaning agent is pressure-bonded. The water absorption and water retention of the water absorbent sheet here means that the water absorbent sheet surface can partially dissolve the sheet-like cleaning agent to be pressure-bonded when water is applied to the water absorbent sheet by a method such as spraying. It means a characteristic that can retain a certain amount of moisture. If excessive moisture remains, the entire sheet-like cleaning agent is dissolved or swollen. Therefore, it is desirable that the excess moisture be absorbed and dissipated inside. For this reason, it is preferable that the water absorption rate measured according to JISL 1907 (1994) 5.1.1 is within 3 seconds. When the water absorption speed exceeds 3 seconds, the sheet-like cleaning agent is too soft or the quality is liable to be lost when adhering to the sheet-like cleaning agent. More preferably, the water absorption rate is within 2 seconds.
Moreover, although a hydrophilic raw material can also be used for a water absorbing sheet, even if it is a hydrophobic raw material, it can also hydrophilize so that the surface part may have water absorbing property.

Further, the water absorbent sheet needs to have compression elasticity in a wet state. This is because the foaming property is increased in a wet state and the cleaning effect is enhanced.
Regarding the compression elasticity of the water-absorbent sheet, the compression modulus according to JISL1018 (knit fabric test method) is preferably 80% or more, more preferably 85% or more, and still more preferably 90% or more. It is convenient for enhancing the foaming effect. If a material that maintains such compression elasticity even in a wet state is selected, the foaming effect at the time of washing can be further improved.

The water-absorbent sheet is not particularly limited as long as it has the above-described characteristics, and fiber sheets and sponge sheets having compression elasticity even in a wet state are used.
As the fiber sheets, for example, woven fabrics, knitted fabrics, nonwoven fabrics, and webs having a bulky property due to a crimped structure or the like are preferable in terms of compression elasticity.
The material of the fiber sheet is not particularly limited, but celluloses such as cotton, hemp and rayon, polyesters such as polyethylene terephthalate, polybutylene terephthalate and polytrimethylene terephthalate, nylon 6, nylon 6, 6 and the like Preferable examples include polyamides, polyolefins such as polyethylene and polypropylene, polyurethanes and silk. It is preferable to use a fiber sheet containing silk from the viewpoint of softness and familiarity with the skin. When silk is used, not only is the skin soft, but also contains a soluble skin care ingredient such as sericin, which is suitable for skin care as well as washing.

As the sponge sheets, foamed sheets made of synthetic rubbers such as NBR, natural rubbers, polyurethanes, etc. or natural materials such as cellulose can be preferably used. As the cellulose sponge, one obtained by slicing a foam in a compressed and dried state can be preferably used.
The foam structure preferably has an open cell structure at least near the surface of the sheet for the purpose of expressing water retention and moisture permeability. At this time, if the open cell is made wider on the inner side than the surface, the adhesion is improved by the so-called anchor effect.

These water-absorbing sheets can be used alone or in combination of two or more. When combining 2 or more types, it is appropriate to use a sheet having at least one layer having compression elasticity. In the case of lamination, an adhesive may be used, or thermal bonding may be used. A hot melt can also be used in combination.
More preferably, in order to improve the adhesion between the sheet-like cleaning agent and the water-absorbent sheet, a concave-convex structure such as a dot-like or linear protrusion or groove is formed on the side of the water-absorbing sheet in contact with the sheet-like detergent. If it is set, the adhesion area can be increased, and the adhesion is further improved.
Further, it is preferable to provide a fiber sheet having a network structure, for example, a fiber sheet processed so that the fiber bundle is in a mesh shape so as to be in contact with the sheet-like cleaning agent, in order to increase the adhesive strength.
As the water-absorbent sheet, a sheet having one layer or two or more layers can be used, but a sheet having a thickness of about 1 mm to 10 mm can be preferably used in terms of handling properties, flexibility during cleaning, and the like. When using a water-absorbent sheet that swells when wet, such as a compressed cellulose sponge, the dry thickness can be about 0.5 mm to 2 mm.

A preferable condition for bonding the sheet-like cleaning agent and the water absorbent sheet will be described.
For the water absorbent sheet, moisture is applied to the bonding surface immediately before bonding. For example, a spraying method etc. are mentioned as a preferable method. In any case, the amount of moisture is not particularly limited as long as the adhesion surface is slightly wet. What is necessary is just to be a grade which a component melt | dissolves a little, without being too soft when a sheet-like cleaning agent is applied to the surface.
Next, a sheet-like cleaning agent is layered on the water-absorbing sheet surface holding moisture, and pressure bonding is performed using a pressure bonding means such as a roll press. When crimping, the sheet may be pressed at room temperature, but may be heated to about 30 to 70 ° C. in order to enhance the deformability of the sheet-like cleaning agent. These processes are preferably performed in an in-line integrated process because of high productivity.

Thus, a sheet-like skin cleaning tool in which the sheet-like cleaning agent and the water-absorbent sheet are bonded can be obtained. The adhesive strength between the sheet-like cleaning agent and the water-absorbent sheet is preferably in the range of about 0.4 N / 15 mm to 5 N / 15 mm. Within this range, the possibility of delamination between the sheet-like cleaning agent and the water-absorbent sheet is low during use, and the practicality is excellent. In addition, this adhesive strength is measured based on the measuring method of peeling strength prescribed | regulated to JISL1086 (adhesion bond test method).
Further, the sheet-like cleaning agent may be provided on one side with respect to the water-absorbing sheet, but when used as a cleaning tool for a large area such as a body, the sheet-like cleaning agent may be provided on both sides of the water-absorbing sheet. preferable. The size of the sheet cleaning agent is not particularly limited, and can be processed into an arbitrary size according to the purpose.

Next, preferred embodiments of the present invention will be described with reference to the drawings showing a laminated structure, but are not limited thereto.
(Manufacture of sheet detergent)
A sheet-like cleaning agent was prepared by blending hydroxypropylmethylcellulose as a water-soluble polymer, fatty acid sodium salt as a surfactant, and glycerin as a humectant. The thickness of this sheet was 100 μm, the elongation at break in the tensile test was 3.8%, the break stress was 2.5 MPa, and the film was highly flexible. (Tensile interval (grip interval) 30 mm, tensile speed 6 mm / min)
Further, the dissolution rate in water was 11 seconds at 25 ° C.

Example 1
As shown in FIG. 1, the water-absorbent sheet has a configuration in which the sheet-like cleaning agent of the production example is bonded to one side of a dry cellulose sponge sheet in a compressed state.
Since this cellulose sponge sheet has water retention and high water absorption, the excess water sprayed on the surface quickly penetrated into the interior. For this reason, the soap partly dissolved in the bonding process was absorbed and present in the pores of the porous structure of the cellulose sponge sheet, and the adhesive strength was high. In addition, the sheet-like cleaning agent did not swell or deformed in the bonding process, and retained compression elasticity in a wet state, and exhibited a high-grade appearance.
In addition, when used in bathing or showering, the cleaning tool of the present invention had a good foaming property as in the case of using a normal soap and a fiber sheet in spite of being a thin sheet.

(Example 2)
As shown in FIG. 2, a web having a crimped structure in which polyester fibers and cotton are mixed is used as a water-absorbent sheet, and the water-soluble sheet-like cleaning agent of the production example is adhered to this one side. It is.
Since this mixed web had water retention and high water absorption, the excess water sprayed on the surface quickly penetrated into the interior. For this reason, the soap partly dissolved in the bonding process is in a state of adhesion with the fibers near the surface of the web, and part of the soap is absorbed into the fiber gap and solidified, and the adhesive strength is high. The material web retained compression elasticity even in the wet state. In the bonding process, the sheet-like cleaning agent did not swell or deformed, and exhibited a high-grade appearance like that of Example 1.
At the time of use, the foaming property was good as in the case of using a normal soap and a fiber sheet in combination even though the sheet was thin.

(Example 3)
As the water-absorbent sheet of the base material, a sheet in which a polyurethane sponge sheet and a mesh-like cotton nonwoven fabric are bonded with a hot melt material as shown in FIG. 3 (the hot melt material is omitted in the figure) is used. The example of the structure which laminated | stacked and adhere | attached the sheet-like cleaning agent of an easily water-soluble manufacture example on the shape-like cotton nonwoven fabric.
The mesh-like cotton nonwoven fabric has high water retention because it is a hydrophilic material. On the other hand, since it has a mesh-like structure, excess water sprayed on the surface quickly penetrates into the interior, and the sheet-like cleaning agent is water-resistant during crimping. The laminated sheet of the base material retained compression elasticity even in a wet state.
The dissolved soap component was taken up by capillarity in the fiber gap in the mesh portion and remained after drying as it had a high adhesive strength.
At the time of use, the foaming property was good as in the case of using a normal soap and a fiber sheet in combination, although the sheet was thin.

Example 4
As the water-absorbent sheet, as shown in FIG. 4, a sheet in which a polyurethane sponge sheet and a mesh-like cotton nonwoven fabric are bonded with a hot-melt material (the hot-melt material is omitted in the figure) is used. The sheet-like cleaning agent of the water-soluble production example is laminated and bonded, and the water-soluble sheet-like cleaning agent is directly bonded to the sponge sheet on the opposite side.
The mesh-like cotton nonwoven fabric has high water retention. On the other hand, since it has a mesh-like structure, the excess water sprayed on the surface quickly penetrates into the polyurethane sponge sheet side, and the sheet-like cleaning agent can be swollen with water during crimping. It was possible to bond without deformation. The dissolved soap was taken up by capillarity in the fiber gaps in the mesh portion and remained after drying as it was, and the adhesive strength was high. Similarly, the other side of the sheet-like cleaning agent was solidified in a state where a partially dissolved soap component penetrated into the sponge, and was excellent in adhesiveness.
At the time of use, the laminated sheet of the base material maintained compression elasticity even in a wet state and had good foamability.
Since the sheet-like cleaning agent is provided on both sides of the base sheet, it can be preferably used for body cleaning of a large area.
