DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an embodiment of the liquid detergent product for partial washing of the present invention (hereinafter referred to as “the product”). In FIG. 1, the product 1 is schematically
It comprises a container 2 and a liquid detergent 3 filled in the container 2.

First, the structure of the container 2 will be described.
The container 2 includes a container body 10 that stores the liquid detergent 3,
It comprises a lid member 20 detachably attached to the opening 11 of the container body 10 and a cap 30 detachably attached to the neck 12 of the container body.

The container body 10 is a squeeze container made of high-density polyethylene, and has a body 14 having a substantially elliptical cross section and a neck 12 having a circular cross section formed above the body.
And an opening 11 formed at the upper end thereof and having a circular section with a smaller diameter than the neck 12. The body 14 is dented when pressed (squeezed) by hand, and returns to its original shape when the pressure is released. It has flexibility and elastic return force.

The cover member 20 is made of high-density polyethylene having a density of 0.95 gcm ^-3 , and is formed into a closed cylindrical shape.
The inner peripheral surface of the cylindrical wall 21 is fitted to the outer peripheral surface of the opening 11 of the container main body so as to be detachably attached to the container main body 10.

At the center of the cover plate 22 of the cover member 20, a pouring hole 23 through which the liquid detergent 3 in the container body can be poured is formed. The diameter d of the pouring hole 23 is 1 mm,
Further, its shape is formed in a tapered shape whose diameter gradually increases upward.

A large number of brushes 24 formed of high-density polyethylene integrally with the lid member 20 are provided around the pouring hole 23.
Are formed upward from the upper surface of the lid plate 22. Each of the brushes 24 has a length L of 14 mm. These brushes 24 are formed so as to surround the periphery of the pouring hole 23 in multiple layers, and the density of the flocks is
It is about 95 cm- ² .

The cap 30 is formed in a closed cylindrical shape,
The inner peripheral surface of the cylindrical portion 31 is fitted to the neck 12 of the container body 10. An annular projection 13 is formed on the neck portion 12 of the container body, and a bearing groove for engaging with the annular projection 13 is formed on the inner peripheral surface of the cylindrical portion 31 of the cap. By engaging, the cap 3
0 is mounted so as to be snapped to the container body 10.

From the center inside the top plate 32 of the cap 30,
The stopper 33 extends downward, and the tip of the stopper 33 is attached to the outlet hole 2 with the cap 30 attached to the container body 10.
3 is formed in a conical shape whose diameter gradually decreases downward so as to close it.

Next, the composition of the liquid detergent 3 filled in the container body 10 will be described. This liquid detergent 3 contains 20% by weight of a surfactant and 1% by weight of a chelating agent,
The viscosity at 30 ° C. is 30P.

The above surfactant comprises an anionic surfactant and a nonionic surfactant. As the anionic surfactant, α-olefin sulfonate (AOS) is 3
Wt%, soap oleate contains 10 wt%, the nonionic surfactant, polyoxyethylene (10) alkyl (C ₁₂ -C ₁₃₎ ether is contained 7% by weight.

The liquid detergent 3 also contains 1% by weight of sodium salt of ethylenediaminetetraacetic acid as a chelating agent. This liquid detergent 3 contains, in addition to the above components, 5% by weight of polyethylene glycol monobutyl ether,
It contains 5% by weight of ethanol and 0.5% by weight of fragrance, and the remainder is purified water.

Next, the operation and cleaning method of the product 1 will be described. In the product 1, when the cap 30 is attached, the stopper 33 closes the pouring hole 23, so that the liquid detergent 3 does not leak to the outside even if the container body 10 falls.

In use, the cap 30 is attached to the annular projection 1.
Since it is snap-fastened to the container body 10 by 3, it can be easily removed from the container body 10 simply by pulling it out by hand. At this time, the plug 33 is removed at the same time, and the pouring hole 23 is opened.

In this state, when the container body 10 is turned over and its body is pressed (squeezed) by hand, a part of the liquid detergent 3 is discharged from the container body 10 through the discharge hole 23 and the brush 2 is discharged.
4. Temporarily stored in the gaps. At the time of pressing by hand, since the viscosity of the liquid detergent and the diameter d of the pouring hole 23 are suitably adjusted, a sufficient amount (for example, 2 ml to 20 ml) of the liquid detergent necessary for one partial washing is used. Is discharged by a single press, and when the press is released, the container body 1
With the flexibility and elastic restoring force of 0, the shape of the body returns to the original shape, and during this time, air is discharged from the pouring hole 23 into the container body 10.
The liquid detergent stops flowing out.

The brush 24 is applied to the surface of the object to be cleaned such as a woven cloth to be partially washed, and the brush is brushed at the tip of the brush. Are supplied to the surface of the object or into the tissue from the tip thereof along..., And the object is cleaned by a cleaning operation.

Since the liquid detergent supplied to the object to be cleaned contains the anionic surfactant and the nonionic surfactant in suitable concentrations, respectively, the brushes 24 having appropriate flexibility and elastic restoring force are provided. When the object is brushed, the physicochemical cleaning effect of the surfactant and the brushing effect of brushing work together to release contaminants attached to the object from the tissue of the object. . After repeating the brushing an appropriate number of times, rinse with warm water, etc.,
The object is cleaned.

Since the liquid detergent of the present product contains a chelating agent, the cleaning effect, especially on dust stains, is improved as compared with the conventional partial washing detergent containing no chelating agent.
In addition, polyethylene glycol monobutyl ether contained in this liquid detergent, as a solvent, has the effect of promoting system stabilization, softening hardened oil stain substances, and enhancing the cleaning effect on oil stains. Ethanol contained in this liquid detergent acts as a penetrating agent, and has an effect of making the liquid detergent well penetrate into thick objects such as shoes.

When the body portion 14 of the container body is pressed (squeezed) to pour out one liquid detergent from the pouring hole 23, the relationship between the diameter d of the pouring hole 23 and the viscosity ρ of the liquid detergent 3 is as follows. is important. As a result of an experiment conducted by a female panelist, generally, the manual pressing force of the body portion 14 becomes substantially constant. Therefore, when the viscosity ρ of the liquid detergent 3 is high, a pouring hole required for pouring out a fixed amount of the liquid detergent. The caliber d of 23 must be increased. When the viscosity ρ of the liquid detergent 3 is low,
The opposite is true.

A squeeze container is filled with a liquid detergent whose composition has been adjusted so as to exert an effect on both oil stains and mud stains, and a sufficient amount (about 10 ml) of the liquid detergent is required for one partial washing. The diameter d of the pouring hole 23 is set to be in a range of 0.4 mm to 3.0 mm so that the liquid can be pushed out by hand and can prevent excessive dripping. It was found that the viscosity needed to be adjusted within the range of 0.01P to 100P.

If the diameter d of the pouring hole 23 is less than 0.4 mm, an excessive pressing force is required to pour the liquid detergent having the above viscosity, which is not practical. When the diameter d exceeds 3.0 mm, an excessive amount of the liquid detergent is poured out with a normal pressing force, and the liquid dripping easily occurs. From this point of view, the diameter d of the pouring hole 23 is in the range of 0.6 mm to 2.0 mm, and in particular, 0.1 mm.
More preferably, it is in the range of 6 mm to 1.6 mm.

When the viscosity of the liquid detergent is less than 0.01P,
The dripping from the pouring hole 23 becomes severe, making it difficult to store in the gaps between the brushes 24. It is also difficult to formulate a liquid detergent for use. If the viscosity exceeds 100 P, it becomes difficult to dispense a necessary and sufficient amount of liquid detergent with a normal hand pressing force, even if the diameter d is increased within a practical range. From this viewpoint, the viscosity of the liquid detergent is more preferably in the range of 1P to 70P at 25 ° C.

In the container described above, the pouring hole 23 does not necessarily need to be formed at the center of the lid member, and need not be formed only at one place. However, when the ejection holes are formed at eccentric positions or at two or more locations, the ejection holes 23 cannot be closed by the stopper 33 hanging down from the center inside the cap 30 as in the above-described embodiment. It is preferable to use a separate closing means, for example, a means in which a cap integrally formed with a stopper is swingably connected to the container body by a hinge.

When the object to be cleaned is cleaned using the product, the brush 24 temporarily stores the liquid detergent discharged from the discharge hole 23 and applies the liquid detergent to the object according to the brushing. The present invention realizes an action of scraping off contaminants supplied and adhered to an object and rubbing and washing.
In order to achieve these effects in a high balance, it is preferable to adjust various conditions of the brush within a suitable range.

The length of the brushes 24 is preferably adjusted within a range of 5 mm to 15 mm. If the length is less than 5 mm, the storage amount of the liquid detergent is limited, and it becomes difficult to smoothly supply the liquid detergent to the object to be cleaned, and the bending stroke of the brush tip decreases, and the rigidity relatively increases. Therefore, the object may be damaged, which is not preferable. If the length exceeds 15 mm, not only is it difficult to integrally mold with the lid member 20 by injection molding or the like, but also the bending stroke is too large, the contaminant scraping force is reduced, and the material is easily broken, which is inconvenient. is there. From this viewpoint, the length of the brushes 24 is more preferably in the range of 9 mm to 13 mm.

The brushes 14 are preferably made of polyolefin. In particular, the density is 0.92 gcm ^{-3 to} 0.9
It is preferably made of polyethylene in the range of 7 gcm ^-3 . In general, the polyolefin is stable to the liquid detergent of the product, is easily formed integrally with the lid member 20 by injection molding or the like, and has rigidity suitable for brushing. In particular, polyethylene having a density of 0.92 gcm ^{-3 to} 0.97 gcm ^-3 is not only available at low cost, but also has suitable rigidity as the brushes 14 of the product. Polyethylene having a density of less than 0.92 gcm ^-3 has insufficient rigidity and insufficient contaminant scraping power, and has a density of 0.97 gc.
Polyethylene exceeding m ^-3 is not preferred because it easily breaks when formed into a brush and may damage an object during brushing.

The shape of the brushes 24 is not particularly limited. However, it is generally preferred that the brush tip has a needle-like shape whose diameter decreases toward the tip. The cross-sectional shape of the brush 24 may be any of a circle, an ellipse, a diamond, a square, and a flat shape. The diameter is also related to the flocking density,
0.2mm to 1.5m in any part of the brush
m is preferably within the range. When the thickness is less than 0.2 mm, not only is molding difficult, but also the brushing effect is insufficient due to being too flexible. If it exceeds 1.5 mm, the rigidity is too high, and there is a risk of damaging the object.

The arrangement of the brushes 24... Is not particularly limited as long as the arrangement surrounds the spouting hole 23. It is preferable to arrange them.

The flocking density is 50 cm ^-2 to 200 cm
It is preferable to be within the range of ^-2 . If it is less than 50 cm ^-2 , the amount of liquid detergent stored is not sufficient, and if it exceeds 200 cm ^-2 , the brushes become too dense and the cleaning power is reduced. In order to achieve this preferred range of the flocking density, the brush 2
The diameter of 4 is preferably in the range of 0.2 mm to 1.5 mm.

In the present product, the concentration of the surfactant in the liquid detergent is in the range of 5% by weight to 60% by weight. 5
If the amount is less than 60% by weight, the cleaning effect on oil stains and the like is insufficient. If the amount exceeds 60% by weight, the liquid detergent becomes viscous and the effect of swelling contaminants is reduced, and the cleaning effect on dust stains and the like is reduced. I do. From this viewpoint, the surfactant comprises an anionic surfactant and a nonionic surfactant, and the surfactant is contained in the liquid detergent in an amount of 10% by weight to 40% by weight.
More preferably, it is contained within the range of% by weight.

Examples of the anionic surfactant include α-olefin sulfonate (AOS), saturated or unsaturated C ₁₂
-C ₁₈ fatty acid soaps, C ₈ -C ₁₈ fatty acid methyl ester sulfonates, and polyoxyethylene alkyl ether sulfate can be suitably used. These are particularly effective in cleaning water-based stains and dust stains. In particular, oleic acid soap has a high detergency, has a viscosity adjusting effect, and is environmentally friendly, and thus can be suitably used as at least a part of an anionic surfactant.

As the nonionic surfactant, polyoxyethylene alkyl ether, polyoxyethylene nonyl phenyl ether and the like can be suitably used. Nonionic surfactants generally have a high cleaning effect on oil stains and the like.

As the chelating agent, malic acid, citric acid, maleic acid, ethylenediaminetetraacetate, nitrilotriacetate, phosphoric acid derivative, sodium polyacrylate, acrylic acid / maleic acid copolymer and the like can be suitably used. Here, examples of the phosphoric acid derivative include 1-hydroxyethane-1,1-diphosphonic acid, aminotri (methylenephosphonic acid), ethylenediaminetetra (methylenephosphonic acid), orthophosphoric acid, metaphosphoric acid, pyrophosphoric acid, and polyphosphoric acid. Can be mentioned.

The present inventor has found that the liquid detergent for partial washing contains a chelating agent, thereby significantly improving the washing effect particularly on mud stains such as shoes and socks. Although the reason for this is not clear, it is considered that the release of the contaminants is promoted by the chelating agent capturing inorganic contaminants such as calcium salts adsorbed on the fibers.

The chelating agent is 0.1% by weight in the liquid detergent.
Preferably, it is contained in the range of 10 to 10% by weight.
If the amount is less than 0.1% by weight, the effect on dust stain is insufficient, and if the amount exceeds 10% by weight, the effect is not so much improved. From this viewpoint, when the chelating agent of the above example is used, it is more preferable to add the chelating agent in the range of 0.5% by weight to 7% by weight.

The liquid detergent used in the present product may contain, in addition to the above-mentioned surfactant and chelating agent, other additives used in ordinary liquid detergents. Examples include for example polyalkylene (C ₂ ~C ₆₎ glycol alkyl (C ₁ ~C ₅₎ ether, a lower (C ₁ ~C ₄₎ alcohols, alkylene glycol derivatives, builders, alkaline agents, enzyme agents, fluorescent agents And perfume.
