Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bleaching detergent product in a squeeze foam container capable of discharging foam suitable for bleaching washing by pressing (squeezing) the body of the container by hand.

[0002]

2. Description of the Related Art A bleaching agent such as sodium hypochlorite and a nonionic surfactant such as polyoxyethylene alkyl ether are mixed for the purpose of cleaning and bleaching or disinfecting clothes, tableware, furniture and toilets. Liquid bleach detergents have been used. When this liquid bleaching detergent is marketed for home use, it is generally called a “squeeze container”.
Often filled. This squeeze container has a synthetic resin body having elastic restoring force, and an openable and closable spout formed on the top thereof. When the spout is opened and the body is pressed by hand (squeeze), An appropriate amount of the liquid bleaching detergent filled therein is discharged from the spout. When the squeeze container is not used, the spout is closed to prevent the liquid bleaching detergent from leaking due to tipping over or vibration.

[0003]

However, a liquid bleaching detergent contained in a normal squeeze container has a bleaching component that is poured out of a spout as a liquid agent, and therefore, penetrates quickly into an object such as a cloth, and has a wide range. It is difficult to apply evenly,
There was a problem that bleaching unevenness easily occurred. In addition, if a part of the object is to be partially bleached and washed, if applied to the part, the boundary between the bleached part and the unbleached part due to the adhesion of the liquid agent may become clear, making it difficult to see. . Further, there is a possibility that the bleaching agent adheres to unnecessary portions due to dripping from the spout, causing decolorization of the dyed product.

In an attempt to solve this problem, a method of applying a liquid bleaching detergent in the form of foam has been studied. If the bleaching detergent is foamed and an appropriate amount is applied to the object, the foam is more slowly penetrating than the liquid, so it can be spread widely.
Also, by changing the thickness of the foam to be applied, the application amount of the bleaching agent can be partially increased or decreased, so that bleaching can be effectively performed without causing bleaching unevenness over a wide area or a part. become. In addition, dripping hardly occurs, and the problem of bleaching unnecessary portions is also reduced.

[0005] One method of foaming the bleaching detergent and discharging it from a container is to fill a so-called "squeeze foam container" with a liquid composition containing a bleaching agent, and when the body of the container is pressed,
A method was considered in which a part of this liquid composition was mixed with air in a container, and the resulting mixture was foamed when passing through a mesh member, and was discharged from a discharge port as a foam. However, in this case, if the conditions for forming the foam are not selected, substantially no foam can be obtained, even if uniform and fine foam cannot be obtained, and even if uniform and fine foam can be obtained, the obtained foam can be obtained. The resulting foam does not disappear in a short time, which causes a problem that the bleaching component does not sufficiently penetrate into the tissue of the object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be described below with reference to the accompanying drawings. (Example 1) FIG.
(Referred to as “this product”). In FIG. 1, the product 1 is composed of a squeeze foam container (hereinafter, referred to as “the present container”) 2 and a liquid composition (hereinafter, referred to as “the present composition”) A filled therein.

The container 2 is made of polypropylene having an elastic restoring force and contains the composition A. The container 2 has a substantially elliptical bottom 11, a substantially elliptical cylindrical body 12, and a cylindrical opening 13 at the top. And a lid member 20 hermetically mounted in the opening 13.

The lid member 20 extends in the container body 10 to the vicinity of the bottom portion 11 and feeds the composition A toward the lid member when the body portion 12 is pressed. A mixing chamber 32 for mixing the present composition A sent from the tube 21 with the air B sent from inside the container body 10
And a mesh member 33 for passing the gas-liquid mixture obtained by mixing in the mixing chamber 32 to generate a foam C by causing foaming, and a discharge port for discharging the foam C generated by the mesh member 33 22. The inner diameter of the liquid sending tube 21 is 2.5 mm.

The mesh member 33 is, as shown in FIG.
It is a net-like woven fabric made of nylon or the like so as to form a gap D from a meridian 33a and a weft 33b. The diameter L of the meridian 33a and the weft 33b is 70 μm, and the mesh gap D is 210 μm. .

The cover member 20 further causes the air B in the container main body 10 to flow through the mixing chamber 3 when the body 12 is pressed.
2 has an air supply hole 31 for supplying air to the air outlet 2 and a bubble supply pipe 34 for supplying the foam C generated by the mesh member 33 toward the discharge port 22.

In the product 1, the composition A contains 3% by weight of hydrogen peroxide as a bleaching agent and 10% by weight of a surfactant.
Contains. The surfactant comprises 1% by weight of α-olefin sulfonate (AOS) as an anionic surfactant
When 1% by weight of polyoxyethylene lauryl ether sulfate, sodium polyoxyethylene (10) of 5 wt% as a nonionic surfactant alkyl (C ₁₂ ~
C ₁₃ ) Consists of ether. The viscosity of the composition A is 1
P.

Next, the method of use and operation of the product 1 will be described. When the product 1 is bleached and washed, when the body 12 is pressed (squeezed) by hand with the container 2 upright, the composition A in the container body 10 is
Depending on the degree of pressing, a part of the liquid is sent from the tube upper end 23 to the mixing chamber 32 through the liquid sending tube 21 by the internal pressure.

On the other hand, a part of the air B stored on the liquid surface of the container body 10 is sent into the mixing chamber 32 through the air supply hole 31 due to the increase of the internal pressure due to the pressing of the body 12, In the mixing chamber 32, the mixture is mixed with the composition A to form a gas-liquid mixture. The resulting gas-liquid mixture is pushed out of the mixing chamber 32 by subsequent pressing,
By passing through the mesh member 33 and passing through the mesh of the mesh member 33, bubbles in the gas-liquid mixture are subdivided to form a foam C
The foam C is discharged from the discharge port 22 through the foam pipe 34.

At this time, since the mesh member 33 has the mesh gap (in the range of 100 μm to 600 μ),
By pressing the body 12 by hand, a uniform and fine cream-like foam C is generated. Further, since the inner diameter of the liquid sending tube is within a preferable range (1.0 mm to 3.0 mm), the mixing ratio of the present composition A and the air B sent to the mixing chamber 32 is suitably adjusted, and When the foam obtained under the combination conditions of the composition of the example and the container is applied to an object, a practically suitable time (for example, within 1 minute)
After maintaining the foam state on the object, the foam quickly disappears.

When the container 2 is inverted and the foam C discharged from the discharge port 22 is applied to the object, the foam C adheres to the surface of the object and becomes liquid with defoaming. A penetrates into the tissue of the object by the penetrating action of the contained surfactant, and exhibits a bleaching effect and a washing effect.

The present composition A contains hydrogen peroxide as a bleaching agent, an anionic surfactant and a nonionic surfactant in a suitable ratio, respectively. Dirt expressed in a well-balanced manner and firmly fixed or dyed on the object can be effectively removed.

At this time, since the foam is held on the object for a short period of time, if the thickness of the foam C is made uniform during this time, the bleaching and cleaning action can be exerted evenly on a wide range of the object. Can be. Also, by locally adjusting the coating thickness of the foam C, the application amount of the bleaching washing component can be locally adjusted, so that even in partial bleaching, the boundary between the bleached portion and the non-bleached portion is noticeable. Can be eliminated. Further, since the non-flowable foam is discharged from the discharge port, there is no fear that the bleaching action may be exerted on unnecessary portions due to dripping from the discharge port.

During the period in which the container 2 is inverted and the foam C is applied to the object, the air B in the container main body 10 is kept at the bottom 1
1 and the lower end of the liquid sending tube 21 is in the air layer, so that the excess liquid composition A
The liquid does not leak out from the discharge port 22 through 1.

After the desired amount of foam has been applied, the container 2 is erected and the pressing of the body 12 is released, so that the body 1
Since 2 has an elastic return force, it returns to the shape before pressing. At this time, since the inside of the container main body 10 has a negative pressure, the foam C remaining in the vicinity of the discharge port 22 is drawn back inside, and the outside air introduced from the discharge port 22 flows back through the air supply hole 31 to return to the container main body. It is introduced into 10 and the air pressure inside and outside is balanced.

The container 2 can generate the foam C even when the body 12 is pressed in an inverted state. In this case, since the gas-liquid layer in the container body 10 is reversed, the present composition A is sent into the mixing chamber 32 through the air supply hole 31, and the air B is mixed through the liquid sending tube 21. Air is supplied into the chamber 32. Thereafter, in the mixing chamber 32, the composition A and the air B are mixed, and the process in which the gas-liquid mixture passes through the mesh member 33 to generate the foam C is the same as that in the upright case.

Next, the structure of the container 2 will be described in more detail. The lid member 20 in the above embodiment is configured by a combination of the discharge member 24 and the lid base material 25. The discharge member 24 includes a substantially cylindrical peripheral wall 26 and the peripheral wall 2.
6 and a discharge pipe 27 integrally formed and extended from the upper part of the discharge pipe 6. The lower end opening 28 of the discharge pipe 27 is
6 is opened downward on the axis of 6, and is curved at an intermediate portion to open the discharge port 22 obliquely upward. Surrounding wall 2
6, a screw is formed on the inner peripheral surface of the lower portion, and the screw is screwed in an airtight manner with a screw formed on the outer peripheral surface of the cylindrical upper cylinder portion 41 protruding from the lid base material 25. Have been.

The cover base material 25 is formed into a substantially closed cylindrical shape having a cylindrical wall portion 42 and a top portion 43 having an open central portion, and a thread is formed on the inner peripheral surface of the cylindrical wall portion 42. The screw is air-tightly screwed and fixed to a screw formed on the outer peripheral surface of the opening 13 of the container body. The upper cylindrical portion 41 is provided so as to protrude upward from the periphery of the central opening of the top portion 43, and the mesh is provided inside the upper cylindrical portion 41 so as to cover the central opening. A member 33 and a foam tube 34 for foaming the foam C generated by the mesh member 33 toward the discharge port 22 are inserted.

The lower end opening 28 of the discharge pipe 27 is connected to the upper end of the foam pipe 34 via a connecting pipe 36 having a side flow hole 35 for allowing the foam C to flow toward the discharge pipe 27. A plug 37 formed so as to fit is mounted.
When the discharge member 24 is screwed clockwise with respect to the lid base material 25, the plug 37 closes the discharge pipe 27 by fitting with the lower end opening 28 of the discharge pipe, and is unscrewed counterclockwise. When opened, the lower end opening 28 of the discharge pipe 27 is opened. The ejection member 24 and the lid base material 25 include
Although not shown, stoppers that engage with each other are provided so that the counterclockwise unscrewing cannot be performed more than the limit.

A cylindrical skirt 44 is hung around the central opening of the top 43 of the lid substrate. In the skirt 44, the mixing chamber 32 and the air supply hole 31 are provided.
And a foaming member 45 having a tube receiving hole into which the liquid feeding tube 21 is fitted and fixed to the lid member 20, is inserted and fixed.

This product having the above-described structure is stored during storage.
If the discharge member 24 is screwed into the lid base material 25, the lower end opening 28 of the discharge pipe 27 is closed by the plug 37, so that even if the container is overturned, the internal composition A inside the container is turned over.
Does not leak.

In use, the discharge pipe 24 is opened by unscrewing the discharge member 24, and the body 1 of the container body is opened.
2, since the discharge pipe 27 is opened, the composition A in the container main body 10 reaches the mixing chamber 32 through the liquid sending tube 21, where the air supplied from the air sending hole 31 is supplied. And the foam C is formed into a foam by passing through the mesh member 33, and the generated foam C is transferred from the foaming pipe 34 to the side flow hole 35 of the connecting pipe 36.
Through the lower end opening 2 of the discharge pipe from inside the cylinder of the discharge member 24.
8 and is discharged from the discharge port 22 through the discharge pipe 27.

After the desired amount of foam has been discharged, the body 12
Is released and the discharge member 24 is screwed into the lid base material 25, the discharge pipe 27 is closed, and even if the container is overturned, the internal composition A does not leak.

In the present container 2, at least the body 12 of the container body is preferably formed using polypropylene, polyethylene, polycarbonate or the like. These synthetic resins have good elastic restoring force and high oxygen permeability, so even if the bleaching agent in the present composition may partially decompose during long-term storage to generate oxygen gas,
This oxygen gas is transmitted through the wall surface of the container body and diffused, so that the container can be prevented from swelling.

In consideration of the above-mentioned elastic restoring force, oxygen permeability, and various physical properties required for the liquid packaging container, the thickness of the body of the container body is in the range of 0.1 mm to 2.5 mm, particularly 0 mm. It is preferable that the thickness be in the range of 0.7 mm to 1.5 mm.

In the present container 2, the mesh gap D of the mesh member 33 is an important requirement for producing a uniform and fine creamy foam C. As a result of the experiment, it was found that a good foam C can be obtained by setting the mesh gap D in the range of 100 µm to 600 µm. If the mesh gap is less than 100 μm, the passage resistance of the gas-liquid mixture increases, and an excessive pressing force is required to generate the foam C. When the viscosity of the composition A is high, the foam C cannot be obtained. ,
In some cases, the net member may be broken by the passage resistance. If the mesh gap exceeds 600 μm, the foam particles of the foam C become coarse, and the purpose of uniformly applying the present composition to an object cannot be fulfilled. From this viewpoint, the mesh gap D of the mesh member 33 is preferably set in a range of 150 μm to 400 μm.

The inner diameter of the liquid feeding tube 21 is 1.0
It is preferable to set it within the range of mm to 3.0 mm. When the inner diameter is less than 1.0 mm, especially when the viscosity of the present composition A is high, the passage resistance at the time of pressing increases, and the balance between the amount of the present composition A sent to the mixing chamber 32 and the air B is lost, Good foam cannot be obtained. If it exceeds 3.0mm,
The amount of the present composition A sent to the air B sent to the mixing chamber 32 becomes excessive, and a good foam cannot be obtained. From this viewpoint, the inner diameter of the liquid sending tube 21 is 1.5 mm to
More preferably, it is within the range of 2.5 mm.

In the present container 2, the number of the air supply holes 31 is not limited to one, and a plurality of air supply holes 31 may be provided so as to surround the outer peripheral surface of the liquid supply tube 21, for example. Sectional area of the air supply hole 31 is preferably in the range of 0.2mm ² ~7.0mm ² in total, 1.0mm ² ~4.0m
More preferably, it is within the range of m ² .

Next, the composition of the composition A will be described in more detail. In the present composition A, any bleaching agent generally used for households or the like can be used.
Examples thereof include hydrogen peroxide, sodium hypochlorite, dichloroisocyanuric acid, and trichloroisocyanuric acid. Hydrogen peroxide contains no chlorine, has a low odor, and has a large bleaching effect, and is therefore particularly suitable as a bleaching agent used in the present invention.

The bleaching agent is contained in the composition in the range of 0.5% by weight to 10% by weight. 0.5 bleach
If the amount is less than the percentage by weight, a sufficient bleaching effect cannot be obtained when the composition is applied to an object as a foam. If the content exceeds 10% by weight, inconveniences such as easy occurrence of uneven bleaching occur. In this respect, a more preferred concentration of the bleach is in the range of 1% to 5% by weight.

The surfactant that can be used in the present composition is an anionic surfactant and / or a nonionic surfactant. Among them, the nonionic surfactant generally has not only a high cleaning effect against oil stains and the like, but also imparts a suitable viscosity to the present composition, and has a fine and suitable hardness by passing through a mesh member with air. It is particularly preferred to incorporate it into the composition as it can produce a foam. The nonionic surfactant is preferably selected from polyoxyethylene alkyl ether and polyoxyethylene nonylphenyl ether.

Anionic surfactants have a high cleaning effect particularly on water-based stains and dust stains. In addition, an anionic surfactant is also useful as a component for adjusting the defoaming speed on an object. Examples of the anionic surfactant include α-olefin sulfonate (AOS), sodium linear alkyl benzene sulfonate, polyoxyethylene alkyl ether sulfate, and C _{8 to} C ₁₈ fatty acid methyl ester sulfonate. In order to enhance the cleaning effect of the present composition, the surfactant to be blended is HL
It is preferable to select those having B of 10 or more, more preferably 12 or more.

The surfactant is contained in the composition A in an amount of from 1% by weight to
It is contained within the range of 50% by weight. When the content of the surfactant is less than 1% by weight, it is difficult to form the composition into fine bubbles with air, and the penetrating power and detergency to the tissue of the target object are weakened. If it exceeds 50% by weight,
The composition becomes excessively viscous, and a strong pressing force is required when the composition is allowed to pass through the mesh member, and foaming becomes difficult, resulting in reduced practicality. From this viewpoint, the content of the surfactant is more preferably in the range of 4% by weight to 20% by weight.

The composition A may further contain, if necessary, a pH adjuster, a builder, a chelating agent, a polyalkylene (C ₂ -C ₂ ) in addition to the bleaching agent and the surfactant, if necessary, as long as the function of the present invention is not impaired. ₆ ) Glycol alkyl (C _1-
C ₅₎ ether, a lower (C ₁ ~C ₄₎ alcohols, alkylene glycol derivatives, enzyme agents, fluorescent agents, may contain additives such as pigments. In particular, in order to improve the stability of the bleaching agent, it is preferable to add a stabilizer such as 1-hydroxyethylidene-1,1-diphosphonic acid.

The viscosity of the composition at 25 ° C. is 100
It is preferably adjusted to P or less. Viscosity 100
If it exceeds P, it will be difficult to pass through the mesh member with normal pressing force, and a good foam cannot be obtained. From this viewpoint, the viscosity of the composition at 25 ° C. is more preferably 70 P or less.

The composition is preferably adjusted to have a pH in the range of 2 to 7. When the pH of the present composition is maintained in the range of 2 to 7, the generation of oxygen gas derived from the decomposition of the bleach in the present composition is suppressed, and the blister of the container generated during long-term storage is prevented. can do. The pH can be adjusted within the above range by adding a pH adjuster if necessary.

The configurations of the present container and the present composition described above are not limited to Example 1 described above. For example, this product may have the configuration of the second embodiment shown in FIG.

It is screwed.

The lid base material 52 is formed in a substantially closed cylindrical shape comprising a cylindrical wall portion 58 and a top portion 59 having an open central portion, and a thread is formed on the inner peripheral surface of the cylindrical wall portion 58. This screw is air-tightly screwed and fixed to a screw formed on the outer peripheral surface of the opening 13 of the container body.

Inside the upper cylindrical portion 57, a mesh member 61 disposed so as to cover the central opening of the top portion 59, and a foam pipe 62 protruding therearound.
A side flow hole 63 formed at the upper end of the foam pipe 62 for letting the foam C flow out toward the discharge pipe 54; and a lower opening of the discharge pipe 54 attached to the top of the foam pipe 62. A plug 64 is formed so as to fit with the plug 55.

When the discharge member 51 is screwed clockwise with respect to the cover base material 52, the plug 64 closes the discharge pipe 54 by fitting with the lower end opening 55 of the discharge pipe.
When the screw is unscrewed counterclockwise, the lower end opening 55 of the discharge pipe 54 is opened. Although not shown, the discharge member 51 and the lid base material 52 are provided with stoppers that engage with each other so that the screw can not be returned counterclockwise more than the limit.

An air suction hole 65 penetrating through the top 59 is provided in the top 59 between the upper cylinder 57 and the foam pipe 62.
A ball-type check valve mechanism 66 for preventing backflow of air B from the container body 10 is formed in the air suction hole 65.
The air in the cylinder of the lid member 50 is supplied into the container body 10 through the check valve mechanism 66 and the air suction hole 65, and the backflow is prevented.

A cylindrical skirt 67 is hung around the central opening of the top 59 of the lid base material and inside the air suction hole 65.
1 are inserted with a gap therebetween so as to form a mixing chamber 69 between the upper end and the net member 61. Skirt 67
A plurality of grooves (68) are formed in the inner wall in the axial direction, and the grooves (68) form an air supply hole 68 from inside the container body 10 to the mixing chamber 69.

In the product 3 of the second embodiment, if the discharge member 51 is screwed into the cover base material 52 during storage, the discharge pipe 54 is closed by the plug 64, so Even if it falls, the inside of the present composition A does not leak.

In use, when the discharge member 51 is unscrewed and the body 12 of the container body is pressed, the discharge pipe 54 is opened, and the composition A in the container body 10 To the mixing chamber 69, where it mixes with the air B supplied from the air vent 68, passes through the mesh member 61 and is foamed. After passing through the hole 63, it is introduced into the lower end opening 55 from inside the cylinder of the discharge member 51, passes through the discharge pipe 54, and is discharged from the discharge port 56.

At this time, since the backflow of the air B in the container body is prevented by the check valve mechanism 66, the air B is not leaked through the air suction hole 65, and the pressing force is not wasted and the solution B is supplied. And the mixing of air in the mixing chamber 69, so that even with a small pressing force, a fine-grained foam can be generated and a sufficient amount of ink can be discharged.

After the desired amount of foam has been discharged, the body 12
Is released, the trunk 12 returns to the state before the pressing. At this time, the foam C remaining in the discharge pipe 54 is drawn back inside, and the outside air introduced through the discharge pipe 54 is supplied to the container until the inside and outside pressures are balanced through the check valve mechanism 66 and the air suction hole 65. It is introduced into the main body 10. If the discharge member 51 is screwed into the lid base material 52 in this state, the discharge pipe 54 is closed, so that even if the container is overturned, the internal composition A does not leak.

If the mechanism of the second embodiment is used, the air supply hole 68 and the air suction hole 65 are provided independently of each other, so that the diameter can be designed to suit each purpose. Even when the pressure is weak, a sufficient amount of good-quality foam C is generated, and when the pressing is released, the outside air is introduced into the container body 10 with a small air resistance, and the dent of the body 12 can be quickly restored.

The samples of Examples 1, 3 and 4 in which the diameter of the liquid sending tube is in the preferable range (1.0 mm to 3.0 mm) are within the range of 00 μm, and the uniform fine bubbles are obtained. Was formed and defoamed within one minute (◎), which was judged to be practically suitable.

In the sample of Example 5, since the inner diameter of the liquid sending tube (3.5 mm) exceeded the preferable range, the amount of bubbles was small, and a slightly non-uniform foam was formed. In the sample of Example 6, the content of the surfactant (2% by weight) was within the range of the present invention but less than the preferred range, so that the foam was coarse, and the sample had a slightly non-uniform appearance. However, the samples of Example 5 and Example 6 were judged to be practicable (○) because the bubbles disappeared within 1 minute.

On the other hand, in the sample of Comparative Example 1, the composition and the inner diameter of the liquid sending tube were the same as those in Example 1, but the foam was too hard because the mesh gap (70 μm) was less than 100 μm. No foam disappeared within 3 minutes (x).
In the sample of Comparative Example 2, the composition and the inner diameter of the liquid sending tube were the same as those in Example 4, but the mesh gap exceeded 600 μm (6
50 μm), the foam was uneven and the appearance was poor,
Defoaming also took time (from 1 minute to 3 minutes) (分).
In the sample of Comparative Example 3, since the composition did not contain a surfactant, the mesh gap of the container (210 μm) and the inner diameter of the liquid transfer tube (2.5 mm) were within the preferable ranges of the present invention. No foam was produced, and no foam was obtained from the discharge port (x).

[0070]

The bleaching detergent product of the present invention has a content of 0.5% by weight.
A liquid composition containing 10% to 10% by weight of a bleaching agent and 1% to 50% by weight of an anionic and / or nonionic surfactant is filled in a squeeze foam container, and a mesh member for foaming built in the container. Mesh gap of 100 μm to 600 μm
By pressing the body of the container by hand, it is possible to discharge a fine foam having a short defoaming time and suitable for bleaching and washing.

When the inner diameter of the liquid sending tube of this squeeze foam container is in the range of 1.0 mm to 3.0 mm, the mixing balance between the liquid composition forming the foam and air is improved, and the texture is improved. It is possible to discharge a foam which is finer and more uniform and has a short defoaming time, which is extremely suitable for bleaching and washing.
