Abstract

PROBLEM TO BE SOLVED: To easily pour out a proper quantity of liquid detergent, and prevent a drip of liquid at in cleaning operation by forming an opening variable pouring-out hole in a pouring-out member to cover an opening of a vessel main body, projecting plural brush bristles to its periphery, and specifying viscosity of the liquid detergent. SOLUTION: At cleaning time, when a pouring-out member 30 is picked by hand and is pulled up from a vessel main body 10, the pouring-out member 30 rises while slidingly moving on a neck part until an annular projection 15 contacts with the lower end of an annular receiving groove 36. As a result, a clearance between a pouring-out hole 33 and a plug body 24 opens, and opening of the pouring-out hole 33 is fully opened, and opening of the pouring-out hole 33 continuously changes according to a moving degree in the middle of rising. The vessel main body 10 is inverted, and when a barrel part 14 is pressed by hand, a liquid detergent 3 is stored in a clearance between brush bristles 35. Next, a brush is cleaned by pushing the brush bristles 35 against a cleaning object. At this time, the pouring-out member 30 is pushed to the vesse main body 10 side, and since the plug body 24 blocks up the pouring-out hole 33, a drip of liquid at cleaning work is prevented. A material whose viscosity at 25 deg.C is adjusted within a range of 0.01 P to 100 P is used as the liquid detergent 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent product for partial washing comprising a liquid detergent and its container, which is suitable for partial washing of clothing, shoes and the like.

[0002]

2. Description of the Related Art Conventionally, stains such as stains and mud adhered to clothing and shoes are removed from nonionic surfactants such as higher alcohols, anionic surfactants such as polyoxyethylene alkyl ether sulfate, and sodium carbonate. And the like, or by washing using a liquid detergent or a powder detergent containing an alkali agent alone or as a mixture. In addition, areas where dirt is firmly attached, such as shirt collars and areas where oil and fat stains are attached, should be “partially washed”.
After rubbing the above-mentioned detergent or soap into the contaminated area at a high concentration, washing is performed by hand-rubbing or mechanically brushing with a brush or the like.

[0003]

However, the work of rubbing and rubbing a high-concentration detergent or soap onto a contaminated area by hand, as well as roughening the hand, is labor-intensive and requires a large amount of fatigue, but the effect is small. In addition, mechanical cleaning with a brush or the like is not a preferable method because the fabric may be damaged due to the shape, material, and cleaning force of the brush. Also, according to any of the methods, the conventional detergent is relatively effective for oil stains such as collar stains, but cannot be expected to be so effective for dust stains adhering to socks and shoe shoes.

[0004] In order to eliminate the complexity of manual washing of the partial washing, a squeeze container is filled with a gel-like detergent, and a pinhole-like pouring hole is formed at the mouth of the container and a large number of holes are formed around the hole. Liquid detergent products for partial washing with a lid member having a brush have been developed. If you use this product, while holding the container with one hand, squeeze and pour out an appropriate amount of detergent, while attaching this detergent to contaminated objects,
The cleaning operation can be simplified because the brush can be brushed off with a brush attached to the container. However, in this product, since the detergent is in a gel form to prevent dripping, a large squeeze force is required for a squeeze for dispensing a required amount of the liquid detergent, and there is a practical problem. In addition, a sufficient cleaning effect was not obtained on the above-mentioned dust stains.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to make it possible to easily discharge an appropriate amount of liquid detergent without dripping during the washing operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below with reference to the accompanying drawings. (Embodiment 1) Fig. 1 shows a preferred embodiment of a liquid detergent product for partial washing (hereinafter referred to as "the product") of the present invention. In FIG. 1, the product 1 generally 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 main body 10 that accommodates the liquid detergent 3, a lid member 20 that is detachably attached to the opening 11 of the container main body, and a closed cylindrical shape that is attached to the neck 12 of the container main body 10. It is composed of an ejection member 30.

The container body 10 is a squeeze container made of high-density polyethylene, and has a body 14 having a substantially elliptical cross section, a cylindrical neck 12 formed above the body, and The body 14 has a cylindrical opening 11 formed to have a smaller diameter than the neck 12. The body 14 has an elastic restoring force that dents when pressed (squeezed) by hand and returns to its original shape when the pressure is released. ing.

The lid member 20 is formed in a closed cylindrical shape, and the inner peripheral surface of the peripheral wall 21 is fitted to the outer peripheral surface of the opening portion 11 of the container body so as to be watertightly and detachably attached to the container body 10. . At the center of the cover plate 22 of the cover member 20, an outflow pipe 23 through which the liquid detergent 3 in the container body flows out is protruded.

The pouring member 30 includes a cover plate portion 32 and a cylindrical wall portion 31.
The inner peripheral surface of the cylindrical wall portion 31 is fitted to the outer peripheral surface of the neck portion 12 of the container body so as to be vertically slidable. A pouring hole 33 having a diameter of 1.0 mm, through which the liquid detergent 3 in the container body can be poured, is formed in a central portion of the lid plate portion 32 of the pouring member 30. The pouring hole 33 is formed in a tapered shape whose diameter gradually increases downward.

A liquid guide tube 34 is suspended from the inner surface of the cover plate portion 32 of the pouring member 30 so as to surround the pouring hole 33. The liquid guide tube 34 has an inner peripheral surface that is formed by the outlet tube 2.
3 is fitted water-tightly and vertically slidably.

At the upper end of the outlet pipe 23, the outlet hole 3 is provided through a connecting pipe 26 having a smaller diameter than the outlet pipe 23 having a side flow hole 25 for allowing the liquid detergent 3 to flow into the liquid guide pipe 34.
A tapered plug 24 whose diameter is reduced upward so as to be fitted to 3 is mounted. The plug 24 is formed so that the maximum diameter of the lower end does not exceed the outer diameter of the outflow pipe 23.

On the upper surface of the cover plate portion 32, a number of brushes 35 formed of high-density polyethylene integrally with the pouring member 30 and having an elastic restoring force are protruded around the pouring hole 33. . These brushes 35 have a length of 14 mm,
It protrudes so as to surround the periphery of the pouring hole 33 in multiple layers, and the flock density is about 95 cm ⁻² .

The neck 12 of the container body and the cylindrical wall 3 of the pouring member
An annular projection 15 orbiting the outer peripheral surface is formed on the neck 12 side in the sliding surface formed by 1 and 2. The annular projection 15 is received on the side of the cylinder wall 31 in the sliding surface,
An annular receiving groove 36 having a vertical width S that allows the pouring member 30 to slide vertically with respect to the neck 12 is formed. When the annular projection 15 is located at the upper end of the annular receiving groove 36, the plug 24 closes the pouring hole 33 in a fully closed state, and the annular projection 15 moves vertically within the annular groove 36. Inside, the outflow pipe 23 and the liquid guide pipe 34 are fitted to each other so that watertightness therebetween is maintained.

Next, the composition of the liquid detergent 3 filled in the container body 10 will be described. This liquid detergent 3 is 25 ° C.
Is 30P, contains 20% by weight of a surfactant and 1% by weight of a chelating agent.

The above-mentioned 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. The product 1 includes a pouring member 30 and a container body 1.
In the state where the annular projection 15 is in contact with the upper end of the annular receiving groove 36 by pushing down by hand in the direction of 0 (downward),
Is closed by the plug 24, the container body 10
The liquid detergent 3 does not leak to the outside even if it falls down.

When the object to be cleaned is washed, the spouting member 30 is picked up by hand and pulled up from the container body 10, and the annular projection 15 moves within the range of the vertical width S, and is positioned at the lower end of the annular receiving groove 36. Until it makes contact, the dispensing member 30 slides up on the neck 12. As a result, at the top of the rise of the pouring member 30, the gap between the pouring hole 33 and the plug 24 is sufficiently opened, and the opening degree of the pouring hole 33 is fully opened. Thus, the opening degree of the pouring hole 33 continuously changes from the fully closed state to the fully opened state.

When the pouring member 30 is appropriately lifted up from the container body 10, the container body 10 is inverted, and the body 14 is pressed (squeezed) by hand, as shown in FIG.
The liquid detergent 3 in the inside flows out of the outlet pipe 2 through the opening 11 of the container body.
3. It flows out through the side flow hole 25, the liquid guide tube 34, and the pouring hole 33 sequentially. At this time, since the gap (opening degree) between the spouting hole 33 and the plug 24 is appropriately adjusted, a single pressing causes a suitable amount of the liquid detergent 3a to be poured out for one partial washing. Are temporarily stored in the gaps between the brushes 35.

Next, as shown in FIG. 3, the brushes 35 are pressed against the object M to be cleaned and brushed.
The liquid detergent 3a stored in the gap between the brushes is supplied to the surface or tissue of the object M from the tip thereof along the brushes 35, and the object M is cleaned by a brushing operation.

At this time, the ejection member 30 is pushed toward the container body 10 by the pressing at the time of cleaning, and the stopper 24 is inserted into the ejection hole 3.
3 is closed. As a result, excess outflow of the liquid detergent from the container body 10 is prevented, and liquid dripping from the pouring hole 33 is prevented during the cleaning operation. Further, when it is desired to additionally supply the liquid detergent to the object M, the discharging member 30 may be lifted and opened, and the body portion 14 may be pressed to discharge a required amount of the liquid detergent.

The liquid detergent supplied to the object M contains an anionic surfactant and a nonionic surfactant at suitable concentrations, respectively. At the time of brushing, the physicochemical cleaning effect of the surfactant and the brushing effect of brushing work together to release contaminants attached to the object M from the tissue of the object. If the object is cleaned by repeating rinsing an appropriate number of times and rinsing with warm water or the like, 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 a 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 through the pouring hole 33, the relationship between the opening degree of the pouring hole 33 and the viscosity ρ of the liquid detergent 3 is as follows. is important. Generally, since the pressing force of the body portion 14 by a human being is substantially constant, when the viscosity ρ of the liquid detergent 3 is high, the opening degree of the pouring hole 33 required for pouring out a fixed amount of the liquid detergent is increased. There must be. Viscosity ρ of liquid detergent 3
If is low, the opposite is true.

When the viscosity of the liquid detergent is less than 0.01P,
The dripping from the pouring hole 33 becomes severe, and it becomes difficult not only to adjust the pouring amount to an appropriate amount by adjusting the vertical position of the pouring member 30, but also to the oily dirt due to this viscosity. It is also difficult to formulate an effective liquid detergent for partial washing. If the viscosity exceeds 100P, even if the pouring hole 33 is fully opened by adjusting the vertical position of the pouring member 30, it becomes difficult to pour out a necessary and sufficient amount of liquid detergent with normal hand pressing force. It becomes impractical. From this viewpoint, the viscosity of the liquid detergent in the present product is in the range of 0.01P to 100P at 25 ° C. In particular, 1P ~
It is preferable to be within the range of 70P.

When the object to be cleaned is washed using this product, the brush 35 temporarily stores the liquid detergent discharged from the discharge hole 33 and applies the liquid detergent to the object in accordance with 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 35 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 possibility of damaging the object increases, which is not preferable. If the length exceeds 15 mm, not only is it difficult to integrally mold by injection molding or the like, but also the bending stroke is too large, so that the contaminant scraping force is reduced and the material is easily broken. From this viewpoint, the length of the brushes 35 in this product is 5 m
It is preferable to set it in the range of m to 15 mm. In particular, 9
It is preferable to set it in the range of 13 mm to 13 mm.

The brushes 35 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 . Polyolefin is generally stable to the liquid detergent of the product, can be easily formed integrally with the pouring member 30 by injection molding or the like, and has rigidity and elastic return force suitable for brushing. I have. Especially the density is 0.92
Polyethylene of gcm ^{-3 to} 0.97 gcm ^-3 is not only available inexpensively, but also has suitable rigidity and elastic restoring force as the brushes 35 of this product. 0.92 density
Polyethylene of less than gcm ^-3 is insufficient in rigidity and insufficient in scraping power of contaminants, and polyethylene having a density of more than 0.97 gcm ^-3 is easily broken when molded into a brush, and the object to be cleaned when brushed. It is not preferable because it may be damaged.

The shape of the brushes 35 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 35 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 35 is not particularly limited as long as the arrangement surrounds the spouting holes 33. For example, four to fifteen rows are formed in a ring around the spouting holes 33. It is preferable to arrange them in such a manner.

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 realize this preferred range of the flocking density, the brush 3
The diameter of 5 is preferably in the range of 0.2 mm to 1.5 mm.

In the present product, the preferred concentration of the surfactant in the liquid detergent is in the range of 5% to 60% by weight. If it is less than 5% by weight, the cleaning effect against oil stains and the like is insufficient, and if it 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. descend. From this viewpoint, the surfactant comprises an anionic surfactant and a nonionic surfactant, and the surfactant is contained in the liquid detergent by 10% by weight.
More preferably, it is contained within the range of ４０40% by weight.

As the anionic surfactant, for example, α-
Olefin sulfonate (AOS), saturated or unsaturated C ₁₂ -C ₁₈ fatty acid soap, C ₈ -C ₁₈ fatty acid methyl ester sulfonate, polyoxyethylene alkyl ether sulfate and the like 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 nonylphenyl 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 it exceeds 10% by weight, the effect is not improved more than the limit. 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.

(Embodiment 2) In this embodiment 2, the container body neck and the spouting member in the first embodiment are vertically slid by rotating the spouting member relative to the neck. In the following description, the same elements as those described in the first embodiment are denoted by the same reference numerals, and the description is omitted or simplified.

FIG. 4 shows the product of the second embodiment. In FIG. 4, the product 5 generally comprises a container 6 and a liquid detergent 3 filled in the container 6. This liquid detergent 3
Has a composition similar to that used in Example 1.

The container 6 comprises a container body 40 for accommodating the liquid detergent 3, a lid member 20 similar to that of the first embodiment, which is removably attached to the opening 41 of the container body, and a container body 4
And a spout member 50 having a cylindrical shape with a lid, which is fitted to the neck 42 of the "0" so as to be able to slide up and down.

The container body 40 is a squeeze container similar to that of the first embodiment except that the shape of the neck 42 is different. The neck portion 42 of the container body 40 is formed with an annular projection 45 that goes around the upper portion of the outer peripheral surface of the neck portion 42, and a screw 46 that goes around the outer peripheral surface is formed below the annular projection 45. ing.

The spouting member 50 has a cylindrical shape with a cover, and has the same configuration as that of the first embodiment except that the shape of the cylindrical wall portion 51 is different. The cylindrical wall portion 51 is formed so that an inner peripheral surface thereof can be vertically slidably fitted to an outer peripheral surface of the neck portion 42, and an upper portion of the fitting portion has an annular shape of the neck portion 42. An annular receiving groove 56 having a vertical width S for receiving the projection 45 and allowing the pouring member 50 to slide vertically with respect to the neck 42 is formed. A screw 57 that is screwed with the screw 46 formed on the neck 42 is provided below the annular receiving groove 56.
Are formed.

When the pouring member 50 is twisted clockwise by hand, it is guided by the threads 46 and 57 and descends while rotating.
It stops with the upper end of the annular receiving groove 56 in contact with the annular projection 45 of the container body. At this time, the plug 24 is fitted into the pouring hole 53, and the pouring hole 53 is fully closed.

In this state, when the spouting member 50 is twisted counterclockwise by hand, the spouting member 50 rises while being rotated by being guided by the threads 46 and 57, and the lower end of the annular receiving groove 56 is closed.
5 stops in contact with 5. At this time, the pouring hole 53 is opened from the stopper 24 and is fully opened. Therefore, by adjusting the counterclockwise rotation by hand, the opening degree of the pouring hole 53 can be arbitrarily set between the fully closed state and the fully opened state.

In the present product 5, when the pouring member 50 is screwed to the right until it stops, the pouring hole 53 is closed by the stopper 24, so that even if the container body 40 is turned over, the liquid detergent 3 does not leak outside.

In use, when the pouring member 50 is picked up by hand and twisted leftward, the gap (opening degree) between the pouring hole 53 and the plug 24 is changed from fully closed to fully open in accordance with the amount of twist. It changes continuously up to. Then, when the rotation of the pouring member 50 is stopped at a position where the opening degree is appropriate, the container body 40 is inverted, and the body portion 44 is pressed (squeezed) by hand, the liquid detergent 3 in the container body 40 is It flows out from the opening 41 of the container body through the outflow pipe 23, the side flow hole 25, the liquid guide pipe 54 and the pouring hole 53 sequentially. At this time, the pouring hole 53 and the plug 24
Is appropriately adjusted, and a single pressing causes a suitable amount of the liquid detergent 3 to be poured out for one partial washing, and is temporarily stored in the gap between the brushes 55. You.

Next, the spouting member 50 is twisted until it stops in the right direction, the spouting hole 53 is closed, the brushes 55 are pressed against the object to be cleaned, and the brushes are brushed. The stored liquid detergent 3 is supplied from the tip thereof along the brushes 55 to the surface of the object or into the tissue, and the object is cleaned by a brushing operation.

At this time, since the pouring hole 53 is closed, even if the container main body 40 is pressed in an inverted state, no extra outflow of the liquid detergent occurs, and during the cleaning operation,
There is no drip from the pouring hole 33. Further, when it is desired to additionally supply the liquid detergent to the object, the discharging member 50 may be appropriately twisted to the left, and the body portion 44 may be pressed to discharge a required amount of the liquid detergent from the discharging hole 53.

Various modifications and improvements can be made to this product other than the first and second embodiments. For example,
The change in the opening degree of the pouring hole is formed by forming a plurality of openings having different diameters along the circumference of the rotating disk mounted on the pouring member eccentrically with the pouring hole, and rotating the rotating disk to form these openings. It can also be performed by overlapping with the pouring hole.

The product may have a removable cap for covering at least the cover plate of the pouring member. For example, in the case of the product 1 of the first embodiment shown in FIG. 1, if a cap having a closed cylindrical shape is formed to fit on the outer peripheral surface of the peripheral wall portion 31 of the pouring member 30, the cap is pulled out to allow the pouring. The member 30 is pulled up and rises, and the ejection hole 3

(Comparative Example 4) The container with a variable discharge amount of Example 1 was used as it was, except that the viscosity at 25 ° C was 120P.
And the same evaluation test as described above was conducted.

The evaluation test was performed as follows. Usability evaluation: About 3 c of cotton socks wet with water
A m-square is applied with a mud to make it a mud-stained state, and 10 female panelists conduct a partial washing experiment using each of the above-described examples, and show the ease of dispensing a liquid detergent, the ease of partial washing, and the cleaning effect. The ease of use based on the degree of satisfaction and the like was evaluated at the following levels. A: 80% or more panelists felt easy to use. ；: 60% to 79% of panelists felt easy to use. Δ: 40% to 59% of panelists felt easy to use. X: 39% or less of panelists felt easy to use.

Evaluation of dripping: Applying a mud to a portion of about 3 cm square of a cotton sock wet with water to make a mud stain state,
1 ml of the liquid detergent in each of the above containers
It was poured out and the state of dripping at that time was evaluated. The evaluation results are shown at the following levels. A: Almost no dripping. ；: Almost no dripping. △: There is some dripping. ×: There was dripping considerably.

Table 1 shows the conditions of the sample and the evaluation results. In Table 1, the components of the liquid detergent are indicated by the following abbreviations. AOS; alpha-olefin sulfonates O soaps; oleate soap POE; polyoxyethylene (10) alkyl (C ₁₂ ~
C ₁₃ ) ether EDT; tetrasodium ethylenediaminetetraacetate EGB; polyethylene glycol monobutyl ether EOH; ethanol

[Table 1]

From the results shown in Table 1, the samples of Examples 1, 3 and 4 in which a liquid detergent having a viscosity in the range of 2P to 70P was filled into a container with a variable discharge amount were used. The easiness was good and the dripping hardly occurred. However, the content of the surfactant is preferably in the range (5% by weight to
For the sample of Example 3 which was close to the lower limit of (60% by weight) and had a low viscosity, the evaluation of ease of use was slightly lower than that of the other examples. This indicates that when the content of the surfactant is less than 5% by weight, the cleaning effect becomes unsatisfactory.

On the other hand, in Comparative Example 1, Comparative Example 2, and Comparative Example 3 in which the opening degree of the pouring hole 33 was fixed, although Comparative Example 1 having a viscosity of 30P could be used for a while, In the case of Comparative Example 2 having a low value of (2P), neither ease of use nor dripping is possible. In particular, excess liquid detergent flows out at the time of pouring, making it difficult to use. In the case of Comparative Example 3 having a high viscosity (70P), a necessary and sufficient amount of the liquid detergent is hardly discharged at the time of pouring, and it is difficult to use because a squeeze requires an excessive force.

In the case of Comparative Example 4, the container is of a variable discharge amount type, but the viscosity of the liquid detergent is set higher than the range of the present invention. In this case, even if the opening of the pouring hole 33 is fully opened, the pouring requires a large squeezing force and is not practical.

[0073]
