JP4201691B2 - Container with bleach cleaning carrier for hard surfaces - Google Patents

Description

  The present invention mainly includes a bleach cleaning carrier for hard surfaces for removing stains around kitchens such as kitchen countertops and ranges, and oily burnt stains or sebum, scales and mold stains in sinks, washstands, bathrooms, etc. It relates to an enclosed container.

  Chlorine bleaches and oxygen bleaches such as sodium hypochlorite are mainly used as residential bleach compositions. A bleaching agent for hard surfaces using sodium hypochlorite is excellent in performance but has a great risk to eyes and skin. Furthermore, it has a strong chlorine-based odor and may have a sticky feeling on its hard surface after use, and is resistant to use around kitchens such as kitchen countertops made of artificial marble.

  On the other hand, oxygen-based bleaches need to generate oxygen by mixing bleach and water at the time of use. Therefore, it is suitable for use around water such as a bathroom where water can be easily supplied by a shower or the like. However, it is inconvenient for use at kitchen countertops. Further, since oxygen-based bleaching agents inevitably generate oxygen during storage, it is necessary to use a storage container that takes into account the generated oxygen gas. Therefore, an oxygen bleach is stored in one chamber of a container having a plurality of compartments, and water is stored in another chamber so that the partition between the compartments can be easily communicated. There has been proposed a container in which a function of preventing rupture due to generation of oxygen is provided in a compartment containing a system bleach (see Patent Document 1).

Japanese Patent Laid-Open No. 9-216665

  However, in the container described above, the oxygen bleach powder is stored in the compartment as it is, so that the powder tends to be biased in the compartment, and the mixing becomes uneven when the powder is mixed with water. There is a case where the bleaching power cannot be exhibited quickly. In addition, if the powder is biased in the compartment, the appearance of the container will deteriorate. Furthermore, since the bleaching solution flows out in the scene where it is actually used, it is difficult to uniformly apply the bleaching solution to the target surface and to clean the fine, high and vertical surfaces.

  Accordingly, an object of the present invention is to provide a container with a bleaching cleaning carrier for hard surfaces that can eliminate the disadvantages of the conventional techniques described above.

  In the present invention, a hydrogen peroxide solution having a pH of 7 or less and an alkaline aqueous liquid are separately sealed, at least one of them is impregnated into a carrier, and both are used after being unsealed and mixed. The object is achieved by providing a container with a bleaching washing carrier for hard surfaces, in which the pH of the mixed solution after mixing is set to the alkali side.

  Further, the present invention includes a mixture of a mixture of a hydrogen peroxide solution having a pH of 7 or less and an alkaline aqueous solution that are separately sealed and at least one of which is impregnated in a carrier, and the two are mixed together. The present invention also provides a bleach cleaning method for wiping the surface to be cleaned with the carrier.

  According to the container with the bleached cleaning carrier for hard surfaces of the present invention, since the carrier is impregnated with at least one of hydrogen peroxide solution or alkaline aqueous solution acting as a bleaching agent, the hydrogen peroxide solution in the container And the aqueous alkaline solution are uniformly mixed. Therefore, oxygen can be generated quickly. In addition, the appearance of the container is improved. Prior to use, the hydrogen peroxide solution is stored in a stable state of pH 7 or less, and therefore its alteration and decomposition are unlikely to occur. Furthermore, since the mixing of the hydrogen peroxide solution and the aqueous liquid in the carrier is completed quickly, the impregnated carrier can be used as a wet type cleaning tool. Therefore, it is possible to apply the bleaching solution uniformly to the target surface without preparing a separate cleaning sheet, and it is also easy to apply to fine places, so that stains and scorching stains can be effectively removed. . It can be effectively and safely removed from stains and scorching stains such as high places or vertical places where the dripping is a concern without worrying about dripping.

  The present invention will be described below based on preferred embodiments with reference to the drawings. FIG. 1 is a perspective view, partly broken, of an embodiment of a container with a bleaching cleaning carrier for hard surfaces according to the present invention. The container 1 of the present embodiment is formed into a bag shape by folding a sheet material in half and joining three sides other than the bent portion with a sheet seal or the like. The bag-like container 1 is partitioned by a partition portion 3 extending in the width direction at a substantially central position in the longitudinal direction, and two compartments A and B separated from each other are defined.

  The compartment A is sealed with an alkaline aqueous liquid. On the other hand, the compartment B is sealed with hydrogen peroxide, which is a kind of oxygen bleach. That is, the hydrogen peroxide solution and the aqueous liquid are sealed in separate compartments. The carrier 2 is impregnated with at least one of hydrogen peroxide solution or alkaline aqueous liquid. In the case where the carrier 2 contains foreign matter, it is more preferable that the carrier 2 is impregnated with an alkaline aqueous liquid from the viewpoint of storage stability.

  The partition part 3 that separates the compartments A and B is provided with an easy peeling part 4 at a part thereof. The easy peeling part 4 is also called an easy peel open sealing part, and is a part where the joined state can be easily released by the action of an external force. The partition part 3 including the easily peelable part 4 is formed by joining the mutually facing inner surfaces of the sheet material. The easy peeling part 4 is formed by a method of joining under a condition weaker than the joining condition of the partition part 3 other than the easy peeling part 4 or a method of sandwiching a sheet piece of a different kind from the sheet material so that the joining strength is weakened. Can be formed.

  As shown in FIG. 1, the compartment A is sealed in a state in which the carrier 2 is impregnated with an alkaline aqueous liquid. FIG. 2 shows a perspective view of the carrier 2. The carrier 2 is composed of a fiber sheet having a two-layer structure. Each of the two sheet materials constituting the carrier 2 is a vertically long rectangle having the same shape. The sheet materials are joined together at their four sides. Further, the sheet material is embossed.

The container 1 of this embodiment is used like the method shown in FIG. First, the compartment B where the hydrogen peroxide solution having a pH of 7 or less is sealed is firmly held by hand. As a result, the internal pressure of the compartment B is increased, and the force acts on the easy peeling portion 4 in the partition portion 3. By this action, the joining state of the easy peeling part 4 is released, and the two compartments A and B communicate with each other. As a result, the hydrogen peroxide solution sealed in the compartment B flows into the compartment A. The hydrogen peroxide solution that has flowed into the compartment A is mixed with the alkaline aqueous liquid impregnated in the carrier 2. By this mixing, the pH of the mixed solution is biased toward the alkali side. As a result, hydrogen peroxide bleaching active species (OOH ⁻ ) are generated. The mixing of the hydrogen peroxide solution and the aqueous liquid is further promoted by pinching the compartment A by hand. As soon as the hydrogen peroxide solution and the aqueous liquid are sufficiently mixed, the container 1 is opened and the carrier 2 is taken out. At this point, the carrier 2 is wet with the mixed solution. In other words, it is a wet sheet. By using this carrier 2 to clean the surface to be cleaned, the bleaching solution can be applied uniformly to the surface to be cleaned. Such stains and burnt stains on the surface to be cleaned can be removed more cleanly. There is no need to prepare a separate cleaning sheet.

  Thus, according to the container 1 of the present embodiment, bleach cleaning can be easily performed using hydrogen peroxide, which is a kind of oxygen-based bleach, even in a place where the supply of water is not easy. Therefore, the container 1 of the present embodiment is used for cleaning a place where water supply is not easy and does not want to be excessively wet with water, for example, kitchen countertops and washstands made of artificial marble, gas ranges, etc. Very suitable for cleaning. In addition, before the container 1 is used, the hydrogen peroxide solution is in a state where the pH is maintained at 7 or less, so that its alteration and decomposition hardly occur and can withstand long-term storage. Furthermore, since at least one of the hydrogen peroxide solution and the alkaline aqueous liquid is impregnated in the carrier 2, the two liquids are mixed uniformly. In addition, the appearance of the container is improved. Furthermore, in addition to the chemical action of hydrogen peroxide, the action of mechanical wiping using a wet carrier 2 neatly removes stains such as tea stains and oily dirt that have adhered to the surface to be cleaned. Is done.

Examples thereof include composite fibers and fibers obtained by mixing at least two of these synthetic fibers.

  Also, a porous structure made of resin (for example, a sponge-like structure) can be used as the carrier. In this case, examples of the shape of the porous structure include a sheet shape, a columnar shape, and a rectangular parallelepiped, but are not limited thereto. Examples of the material constituting the porous structure include cellulosic resins, synthetic fibers, and mixtures of two or more thereof. Examples of the cellulose resin include viscose rayon and acetate. On the other hand, examples of the synthetic resin include polyethylene resins, polypropylene resins, polyester resins, polyamide resins, polyacrylonitrile resins, polyvinyl alcohol resins, urethane resins, and melamine resins.

In particular, from the viewpoint of impregnation of the cleaning agent into the carrier, feeling of use of the cleaning agent-impregnated article, and operability, the carrier is paper, non-woven fabric, woven fabric, knitted fabric, pulp sheet or flexible porous It is preferable to use a structure. Incidentally, the basis weight, the cleaning performance and economy ² to 300 g / m ² approximately 20 g / m in terms of preferred.

  As the carrier 2, it is also preferable to use a sheet composed of two sheet materials as described above. The two sheet materials can be arbitrarily combined from the above-mentioned paper, nonwoven fabric, woven fabric, knitted fabric, pulp sheet, or flexible porous structure. At least one of these sheet materials, for example, the sheet material 22 in FIG. 2, preferably has a polishing property or a scraping property against dirt existing on the hard surface. Thereby, the wiping operation of the surface to be cleaned by the wet carrier 2 can be performed more efficiently.

  The surface of the sheet material 22, that is, the cleaning surface of the carrier 2, preferably has a large number of thermoplastic fiber tip portions, and the cleaning surface preferably has a polishing property or a scraping property against dirt existing on the surface to be cleaned. . This further enhances dirt removal. The number of the front end portions is set to a number sufficient to develop sufficient abrasiveness or scraping property against dirt existing on the surface to be cleaned. For this purpose, it is preferable to use a thermoplastic fiber having a fineness of 10 to 150 dtex (hereinafter, this thermoplastic fiber is referred to as a large-diameter thermoplastic fiber). By using the large-diameter thermoplastic fiber, a large number of tip portions are present on the surface of the sheet material 22, and the abrasiveness or scraping property against dirt existing on the surface to be cleaned is enhanced.

  The fiber length of the large-diameter thermoplastic fiber can be set to a fiber length suitable for the method of forming the sheet. For example, when the sheet material 22 is formed by the air array method, the fibers are prevented from falling off from the sheet material 22 by making the fiber length 2 to 15 mm, and the fibers can be uniformly dispersed. In particular, when the fiber length of the large-diameter thermoplastic fiber is preferably 3 to 8 mm, more preferably 4 to 6 mm, dropping of the large-diameter thermoplastic fiber from the sheet material 22 is further prevented, and more uniform. It is possible to form the sheet material 22 having excellent dirt scraping properties. The fiber length within the above range is also a preferable fiber length from the viewpoint of web formation when the sheet material 22 is formed by the air array method. When the sheet material 22 is formed by a wet papermaking method, the fiber length is preferably 0.1 to 20 mm, particularly preferably 0.2 to 15 mm. When the sheet material 22 is formed by a spunlace method, a thermal bond method, or a needle punch method, the fiber length is preferably 30 to 100 mm, particularly preferably 35 to 65 mm.

  By setting the fineness of the large-diameter thermoplastic fiber within the above range, it is possible to improve the scraping property of sticking stains (stain stains such as black tea and burnt oil stains), and the fibers can be uniformly dispersed.

  Examples of large-diameter thermoplastic fibers include polyolefin resins such as polyethylene and polypropylene, polyester resins such as polyethylene terephthalate, acrylic resins such as polyacrylic acid and polymethacrylic acid, vinyl resins such as polyvinyl chloride, and nylon. The polyamide resin is used. When resin-made large-diameter thermoplastic fibers are used, the resin hardness is preferably in the range of R40 to R150 in terms of Rockwell hardness. In particular, it is preferable to use R80 to R150 resins from the viewpoint of improving the dirt scraping property. Of the various raw materials, a composite fiber (core-sheath type composite fiber or side-by-side type composite fiber) made of a combination of two kinds of resins can be used. As the large-diameter thermoplastic fiber, one having crimpability can also be used. Thereby, the feeling of thickness (bulkyness) of the sheet material 22 can be improved, and good wiping comfort can be obtained. As the crimped form, there are a spiral type, a zigzag type, a U-shape, and the like, and any of these is preferably used. One type or two or more types of large-diameter thermoplastic fibers can be used.

  When the sheet material 22 is manufactured by the air lay method, it is possible to three-dimensionally orient the large diameter thermoplastic fibers at random. Therefore, a large number of large diameter thermoplastic fiber tip portions should be present on the surface of the sheet material 22. Can do. In particular, when the fiber having the fiber length is used as the large-diameter thermoplastic fiber, the large-diameter thermoplastic fiber is easily oriented in the thickness direction of the sheet material 22, and the dirt scraping property is enhanced. In addition, by using the above-mentioned fineness as the large-diameter thermoplastic fiber, the rigidity of the large-diameter thermoplastic fiber is increased, and the abrasiveness or scraping property against dirt is further enhanced.

  The other sheet material constituting the carrier 2 can also have the same configuration as the sheet material 22 described above. Or the other sheet material can also be comprised from the material different from the sheet material 22, for example, paper, a nonwoven fabric, a woven fabric, a knitted fabric, a pulp sheet, or a porous structure. In the case of different materials, it is preferable to select the constituent material of the other sheet material from the viewpoint of the impregnation property of hydrogen peroxide solution or aqueous liquid. Specifically, it is preferable to use a fiber sheet containing hydrophilic fibers. Examples of hydrophilic fibers include regenerated cellulose fibers such as rayon and cupra, hydrophilic cellulose fibers such as wood pulp such as softwood kraft pulp and hardwood kraft pulp, and natural cellulose fibers such as cotton pulp and straw pulp. The other sheet material may be composed of only hydrophilic cellulose fibers or may contain other fiber materials. As other fiber materials, for example, heat-fusible fibers (thermoplastic fibers) such as polyethylene fibers and polypropylene fibers can be used. When the heat-fusible fiber is included, the heat sealability of the two sheet materials becomes good. The other sheet material can be manufactured, for example, by various nonwoven fabric manufacturing methods such as the air lay method and the spun lace method, or the wet papermaking method.

  The present invention is not limited to the embodiment. For example, in the above-described embodiment, the hydrogen peroxide solution and the alkaline aqueous liquid are sealed in one container 1 having two compartments A and B separated from each other. The hydrogen peroxide solution and the aqueous liquid may be sealed in individual containers. In this case, at the time of use, each container may be opened and the hydrogen peroxide solution and the aqueous liquid may be mixed.

  Further, the carrier impregnated with the hydrogen peroxide solution is not limited to that of the above-described embodiment, and a sheet material of another form may be used as the carrier.

  Hereinafter, the present invention will be described in more detail with reference to examples. However, the scope of the present invention is not limited to such examples.
