Description

TECHNICAL FIELD The present invention relates to a gel detergent storage container and a detergent product.

Conventionally, various cleaning agents have been used to remove stains that adhere to places where water is regularly flushed, such as toilet bowls. In order to make it work, a cleaning agent has been developed that is adhered to the inner surface of a toilet bowl or the like and is gradually dissolved by running water from the toilet or the like. Such a cleaning agent is used by storing a gel-like cleaning agent in a push-type storage container and attaching it to the inner surface of a toilet bowl or the like.

[Method of using the gel cleaning agent storage container]
When using the gel detergent storage container 100, the user first grips the container body 1 and then places the discharge part 2 side on the surface to which the gel detergent W is to adhere, such as the inner surface of the toilet bowl. Then, the tip 23a of the first protrusion is brought into contact with the surface.

Subsequently, the user presses the container body 1 to push out the gel cleaning agent W from the discharge port 21 . The amount to be extruded is arbitrary and can be adjusted according to the amount desired to be deposited by the user, but 0.5 g to 7 g is suitable. As a result, the gel-like cleaning agent W protruding from between the first protrusions 23 spreads around.

Subsequently, the user separates the gel detergent storage container 100 from the inner surface of the toilet bowl or the like. As a result, the extruded gel cleaning agent W remains attached to the inner surface of the toilet bowl and the like.

[Shape of Adhering Gel Cleaning Agent W]
When adhered in this manner, the gel detergent W adheres to the inner surface of the toilet bowl and the like in the shape shown in FIGS. 4 and 5 .
That is, the gel-like cleaning agent W protruded from between the first protrusions 23 forms the same number of protrusions W1 as the first protrusions 23 .
A groove W2 is formed by the second protrusion 24 in the center of the protrusion W1.
Further, a concave portion W3 that is concave downward is formed by the ejection port 21 in the central portion in a plan view.

[Effects of Gel Cleaning Agent Storage Container]
According to the gel cleaning agent storage container 100 according to the embodiment, as described above, the gel cleaning agent W is adhered to the inner surface of the toilet bowl and the like so as to form the shape shown in FIGS. can be done. By this, the following effects can be obtained.

First, the first protrusions 23 are formed around the discharge port 21, so that the gel cleaning agent W is formed in a flower-like shape in which the plurality of protrusions W1 spread outward in a plan view. can be attached.
Therefore, it is possible to adhere the gel detergent W to the inner surface of the toilet bowl or the like in a shape excellent in design.

In addition, in places where water is regularly flushed, such as the inner surface of the toilet bowl, water often flows from a certain direction, so only one side that hits the water flow tends to dissolve. Even if the gel detergent W can be adhered in a shape with excellent design properties, such a shape often collapses in a short period of time.
On the other hand, according to the gel cleaning agent storage container 100 according to the present embodiment, the second protrusions 24 arranged between the first protrusions 23 cause the protrusions W1 to have the same shape as shown in FIGS. 4 and 5 . A groove W2 is formed as shown. This makes it easier for water to flow uniformly over the entire surface of the attached gel cleaning agent W along the grooves W2. It is possible to suppress that the shape is quickly collapsed due to melting only.

At the same time, since the grooves W2 are formed on the protruding portions W1 of the adhered gel cleaning agent W, the water smoothly flows over the adhered gel cleaning agent W, so that the gel cleaning agent W is removed. It is also possible to prevent water splashing caused by attaching the cleaning agent W.

Such an effect can be obtained by arranging the first projection 23 and the second projection 24 so that the distance between them is even, so that the groove W2 can be formed in the central portion of the projection W1. , the protruding portion W1 is easily melted uniformly, and can be further enhanced. Further, the formation of the groove W2 in the central portion of the protruding portion W1 also contributes to the improvement of the design of the adhered gel cleaning agent W. As shown in FIG.

Further, the portion of the projection 21a closest to the outer periphery of the discharge port 21 is arranged on a straight line connecting the center of the circumference where the second protrusion tip 24a is located and the second protrusion tip 24a. By forming in such a manner, it is possible to increase the amount of the gel cleaning agent W that is extruded at the position corresponding to the second protrusion 24, and it becomes easier to form the groove W2 in the center of the protrusion W1. You can increase the effect.

In addition, since the discharge port 21 has the convex portion 21a at the position corresponding to the gap of the first protrusion 23, the amount of gel detergent W pushed out at the position corresponding to the gap of the first protrusion 23 is increased. The flower-like shape formed by one projection 23 can be clarified. Therefore, it is possible to enhance the design of the attached gel cleaning agent W.
A portion of the recess 21b located closest to the inner peripheral side of the discharge port 21 is arranged on a straight line connecting the center of the circumference where the first projection tip 23a is located and the first projection tip 23a. By forming in such a manner, it is possible to reduce the amount of the gel cleaning agent W pushed out at the position corresponding to the first protrusion 23, and to further enhance such an effect.

Further, according to the gel detergent storage container 100 according to the embodiment, as described above, the container body 1 can be discharged only by bringing the first protrusion tip 23a into contact with the inner surface of the toilet bowl or the like and then pressing the container body 1. Since the gel cleaning agent W can be extruded from the outlet 21 and adhered thereto, the task of attaching the gel cleaning agent W to the inner surface of the toilet bowl or the like is facilitated.

Further, according to the gel cleaning agent storage container 100 according to the embodiment, any amount of gel cleaning agent W can be discharged from the container, and the amount to be adhered can be adjusted according to the period for which the cleaning effect is to be continued. It can be adjusted and used.

Further, according to the gel cleaning agent storage container 100 according to the embodiment, since the gel cleaning agent W is stored in the relatively soft container main body 1, the gel cleaning agent W is stored while the container main body 1 is deformed. can be pushed out, it is possible to reduce the unusable gel detergent W that remains in the container.

[Modified Example of Gel Cleaning Agent Storage Container]
The first protrusions 23 and the second protrusions 24 may be arranged alternately and formed such that the second protrusions 24 are lower than the first protrusions 23. Specifically, The typical shape is not limited to the above.
Also, the shape of the discharge port 21 and its surroundings can be changed as appropriate, although the effects of the projections 21a and the recesses 21b described above cannot be obtained.
In addition, regarding the configuration other than the discharge port 21, the first protrusion 23, and the second protrusion 24, it is sufficient that the gel cleaning agent W inside can be pushed out from the discharge port 21. It is not limited to those consisting of

[Description of gel detergent]
Next, cellulose nanofiber (hereinafter referred to as “CNF”), which is an example of a gel detergent composition suitable as the gel detergent W to be filled in the gel detergent storage container 100 according to the embodiment, and A gel detergent composition containing cyclodextrin (hereinafter referred to as "CNF and cyclodextrin-containing gel detergent composition") will be described. However, this is only an example, and the gel cleaning agent W filled in the gel cleaning agent storage container 100 is not limited to this.

{Structure of gel detergent composition containing CNF and cyclodextrin}
The CNF and cyclodextrin-containing gel detergent composition is formed into a gel and contains CNF and cyclodextrin.
In the present invention, the term "gel" refers to a semi-solid state that does not form a sol at 25°C and has a fixed shape.

(CNF)
CNF refers to fine cellulose fibers obtained by defibrating pulp fibers, and generally refers to cellulose fibers containing cellulose fine fibers having an average fiber width of nanosize (1 nm or more and 1000 nm or less).

Pulp fibers that can be used to produce CNF include chemical pulps such as hardwood pulp (LBKP), softwood pulp (NBKP), bleached thermomechanical pulp (BTMP), stone ground pulp (SGP), pressure stone ground pulp (PGW ), refiner ground pulp (RGP), chemi ground pulp (CGP), thermo ground pulp (TGP), ground pulp (GP), thermomechanical pulp (TMP), chemithermomechanical pulp (CTMP), refiner mechanical pulp (RMP) Used paper manufactured from mechanical pulp, used tea paper, used kraft envelope paper, used magazine paper, used newspaper paper, used leaflet paper, used office paper, used corrugated paper, used white paper, used Kent paper, used imitation paper, used paper for certificates, used waste paper, etc. Pulp, deinked pulp (DIP) obtained by deinking waste paper pulp, and the like. These may be used singly or in combination of two or more as long as the effects of the present invention are not impaired.

Examples of methods for producing CNF include mechanical methods such as high-pressure homogenizer method, microfluidizer method, grinder grinding method, bead mill freeze pulverization method, and ultrasonic defibration method, but are limited to these methods. is not.
For example, pulp fibers subjected to a defibration treatment by a mechanical method may be subjected to a chemical treatment such as carboxymethylation, or may be subjected to an enzyme treatment.
In addition, CNF that has been chemically or enzymatically treated may be defibrated by a mechanical method.

The CNF used in the CNF- and cyclodextrin-containing gel detergent composition preferably has an average fiber width of 1 nm to 100 nm as calculated by the method described below.

The content of CNF in the gel detergent composition containing CNF and cyclodextrin is preferably 0.002% by mass or more and 0.2% by mass or less. For example, when CNF is mixed with water and used as a slurry liquid with a concentration of 2% by mass, it is preferable to add 0.1% by mass or more and 10% by mass or less of the liquid. If it is less than 0.002% by mass, the effect of improving foaming, which will be described later, is not sufficiently exhibited, and if it exceeds 0.2% by mass, foaming increases during stirring during production, making production difficult. Moreover, it is more preferable that it is 0.01 mass % or more and 0.1 mass % or less.

Examples of CNF that can be specifically used include 100% NBKP CNF having an average fiber width (median diameter) of 49 nm. This CNF was obtained by subjecting NBKP to refiner treatment and coarse fibrillation, followed by four treatments and fibrillation using a high-pressure homogenizer.

Here, a method for measuring the fiber width (average fiber width) of CNF will be described.
First, 100 ml of an aqueous dispersion of cellulose nanofibers with a solid content concentration of 0.01 to 0.1% by mass was filtered through a Teflon (registered trademark) membrane filter, and the solvent was filtered once with 100 ml of ethanol and 3 times with 20 ml of t-butanol. Replace.
It is then freeze-dried and coated with osmium to form a sample. For this sample, an electron microscope SEM image at a magnification of 5000 times, 10000 times or 30000 times (for the CNF described in paragraph 0021, a magnification of 30000 times was used) depending on the width of the constituent fibers Observe. Specifically, two diagonal lines are drawn on the observation image, and three straight lines passing through the intersections of the diagonal lines are arbitrarily drawn. Furthermore, the width of a total of 100 fibers intersecting with these three straight lines is visually measured. Then, the median diameter (median diameter) of the measured values is defined as the average fiber width. Note that the average fiber width is not limited to the median diameter of the measured value, and for example, the number average diameter or the mode diameter (mode diameter) may be used as the average fiber width.

(cyclodextrin)
The content of cyclodextrin in the gel detergent composition containing CNF and cyclodextrin is preferably 0.1% by mass or more and 0.5% by mass or less. If it is less than 0.1% by mass, the effect of improving foaming, which will be described later, is not sufficiently exhibited, and if it exceeds 0.5% by mass, although the effect of improving foaming is obtained, the cyclodextrin becomes difficult to dissolve in water. , transparency is not preferred because it is difficult to produce a gel.

The type of cyclodextrin used is not particularly limited, and any of α-cyclodextrin, β-cyclodextrin and γ-cyclodextrin can be used.

(Other compositions)
The CNF and cyclodextrin-containing gel detergent composition contains a surfactant, fragrance, glycerin, water, etc., in addition to CNF and cyclodextrin. Of these, it is essential to contain a surfactant and water.

Surfactants and water are essential for gelling the detergent. As the surfactant, it is preferable to use nonionic surfactants such as ester-type, ether-type, and alkyl glycosides.
Specifically, as the surfactant, for example, polyoxyalkylene alkyl ether, which is a nonionic surfactant, can be used, and the content is preferably 1% by mass or more and 70% by mass or less.
As shown in the examples below, the effect of the present invention can be obtained at both a low concentration of less than 10% by mass and a high concentration of more than 50% by mass of nonionic surfactant. Obtainable.

Perfume is added to the gel cleanser composition to impart a fragrance action in addition to the cleaning action.
The perfume is not particularly limited, but citrus-based, rose-based, and floral-based perfumes can be used, for example.
The content of perfume is preferably 0.5% by mass or more and 10% by mass or less. If it is less than 0.5% by mass, the fragrance effect is often insufficient, and if it exceeds 10% by mass, the detergent composition becomes difficult to gel.

Glycerin is added to control the gel concentration of the gel detergent composition.
The content of glycerin is preferably 3% by mass or more and 20% by mass or less.

{Effect of gel detergent composition containing CNF and cyclodextrin}
Since CNF has a large surface area, it acts as a steric obstacle and has the effect of contributing to the improvement of foamability. In addition, cyclodextrin encloses and covers a hydrophobic substance that hinders foaming, and thus has the effect of reducing the adverse effect on foaming caused by oils such as fragrances in the gel detergent composition. Therefore, by adding CNF and cyclodextrin to the gel detergent composition, it is possible to improve foaming when the gel detergent dissolves in water.
As a result, when the gel-type detergent is attached to the inner surface of the toilet bowl, etc., bubbles are likely to be generated when the gel-type detergent is dissolved by running water, so the user can visually see the effect of the detergent. Makes it easier to see if it's happening.
In addition, the cleaning effect can be improved by increasing the foamability.

In addition, cyclodextrin, when added together with a fragrance, has the effect of encapsulating the fragrance and releasing the encapsulated fragrance upon contact with water. Therefore, by adding the fragrance together with the cyclodextrin, the fragrance can be made difficult to be released until the gel detergent dissolves in water, and the persistence of the fragrance effect of the gel detergent can be enhanced.
In order to efficiently produce such an effect, it is desirable that the perfume be mixed with cyclodextrin in advance and then added to the gel detergent composition in this state.

In addition, CNF is highly thixotropic. That is, the viscosity tends to decrease when subjected to shear stress, and the viscosity tends to increase when the material is at rest.
Therefore, when the user applies force to push out the gel cleaning agent from the container, the viscosity of the gel cleaning agent is lowered, making it easier to push out the gel cleaning agent from the container. In addition, after being adhered to the inner surface of the toilet bowl of the toilet, etc., the viscosity increases and the fixability increases, so the cleaning effect can be exhibited for a long time.

In addition, after being attached to the inner surface of the toilet bowl, etc., the viscosity increases and the fixability increases, so that it is possible to obtain the effect of making it difficult for the gel-like detergent attached to the inner surface of the toilet bowl, etc., to lose its shape. .
Therefore, by including CNF in the gel cleaning agent W stored in the gel cleaning agent storage container 100 according to the embodiment, the shape of the gel cleaning agent W in which the grooves W2 are formed can be maintained for a long time. , the effect of the gel cleaning agent storage container 100 according to the embodiment can be further enhanced.

{Modified example of CNF and cyclodextrin-containing gel detergent composition}
The CNF and cyclodextrin-containing gel detergent composition may further contain carboxymethylcellulose (hereinafter referred to as "CMC").
By binding to the OH groups of CNF, CMC makes it easier for molecules to separate from each other due to steric hindrance due to electrostatic interaction, prevents aggregation of CNF, and enhances its effect.

When CMC is added to the gel detergent composition, the content is preferably 0.5% by mass or more and 10% by mass or less. If it is less than 0.5% by mass, the above effects cannot be sufficiently exhibited, and if it exceeds 10% by mass, gelation becomes unstable and it becomes difficult to maintain the gel state. Furthermore, it is most preferably 1% by mass or more and 5% by mass or less.

The CNF and cyclodextrin-containing gel detergent composition may contain hydroxyethyl cellulose (hereinafter referred to as "HEC"). HEC can also provide the same effects as CMC.
When HEC is added to the gel detergent composition, the content is preferably 0.5% by mass or more and 10% by mass or less. If it is less than 0.5% by mass, the above effects cannot be sufficiently exhibited, and if it exceeds 10% by mass, gelation becomes unstable and it becomes difficult to maintain the gel state. Furthermore, it is most preferably 1% by mass or more and 5% by mass or less.
