Description

  TECHNICAL FIELD The present invention relates to a gel detergent composition used by being adhered to a hard surface such as a toilet bowl, glass, a window, a door, or a bathroom wall.

  2. Description of the Related Art Conventionally, various cleaning agents have been used to remove dirt attached to a hard surface of a toilet bowl or the like and create a sanitary environment. For example, a flush toilet flushing agent is an on-tank or in-tank flushing detergent designed to be able to elute the flushing water into the flush water by being installed in the hand washing section of the flush toilet or in the water storage tank. Have been. However, in recent years, tankless flush toilets have become widespread, and there is a disadvantage that on-tank or in-tank flush cleaners cannot be applied to tankless flush toilets.

  On the other hand, there is known a toilet cleaning agent for a rim portion that is installed on a rim portion of a toilet bowl and allows the cleaning agent to flow into flush water flowing to the toilet bowl. Rim toilet cleaners can be applied to tankless flush toilets, but they need to be removed from the rim before and after use. It is the current situation.

  Therefore, in recent years, a gel detergent that is used by being attached to the surface of a toilet bowl of a toilet has been developed. For example, Patent Literature 1 discloses a toilet gel-like cleaning agent containing a polyoxyethylene having a degree of polymerization of 15 to 50 and a polyoxyethylene alkyl ether composed of an alkyl group having 12 to 18 carbon atoms. It has been reported that by attaching the cleaning agent to the surface of the toilet bowl, the cleaning agent can be continuously released into the running water even when it comes into contact with the running water while maintaining the state of being attached to the surface of the toilet bowl.

  The gel detergent is used by being contained in a container, discharged from a discharge port of the container, and adhered to a surface to be adhered. However, the conventional gel cleaner has less luster and further improvement in appearance is desired.

  Conventionally, a gel-type cleaning agent has been developed to form a desired shape on the surface to be adhered by devising the shape of the discharge port of the container to be housed in order to capture consumer orientation. Have been. However, in the conventional gel-like cleaning agent, if the shape of the discharge port of the container is devised to form a complicated shape on the surface to be adhered, there is a drawback that a complicated shape as designed cannot be formed. . Furthermore, in the conventional gel-like cleaning agent, a thread may be pulled from a discharge port of a container at the time of discharging to a surface to be adhered, and a complicated shape is formed as designed on the surface to be adhered. There is also a problem that it becomes more difficult.

Specifically, by causing water to come into contact with the gelled detergent composition of the present invention attached to the hard surface and attached to the hard surface, components contained in the water flow out, and cleaning and disinfection of the hard surface can be performed. Done.

  In the gel detergent composition of the present invention, the hard surface to be cleaned may be any hard surface capable of contacting with water, for example, a toilet bowl, a hand-washing part of a toilet, glass, windows, and doors. , Bathroom walls and the like. Among these, a toilet bowl is preferable.

  When the gel detergent composition of the present invention is used for cleaning a toilet bowl, the gel detergent composition of the present invention may be attached to a portion that comes into contact with water supplied as flush water. Such an attachment site is preferably the surface of a toilet bowl, but in the case of a flush toilet having a hand-washing portion on a water storage tank, the sink of the hand-washing portion (surface of the upper lid of the water storage tank). There may be. Even when the gel detergent composition of the present invention adheres to such a site, it has excellent adhesion to the surface to be adhered, so that flush water flows or is supplied to the water storage tank as flush water. Even if it comes into contact with the water to be produced, the adhered state can be maintained.

  In order to adhere the gel-like detergent composition of the present invention to a hard surface, the gel-like detergent composition of the present invention may be extruded or ejected from a container containing the gel-like detergent composition to the surface to be adhered and discharged.

  Further, the container containing the gel-like detergent composition of the present invention has a shape of an ejection port for ejecting the gel-like detergent composition, and the ejected gel-like detergent composition has a desired shape on the surface to be adhered. What is necessary is just to be designed so that it can form.

[Shape formed on adherend surface]
In the gel detergent composition of the present invention, the shape formed on the surface to be adhered after being discharged from the container is not particularly limited. The conventional gel-like detergent composition has a drawback that even if it is attempted to form a complicated shape on the surface to be adhered, it cannot be formed into a shape as designed. A complicated shape can be formed on the surface. Furthermore, in the present invention, in the conventional gel-like cleaning composition, when trying to form a complicated shape on the surface to be adhered, a gap is formed between the gel-like cleaning composition and the surface to be adhered, Although there is a disadvantage that the property is lowered, in the present invention, such a disadvantage is solved, and even if a complicated shape is formed on the surface to be adhered, a gap is generated between the gel-like detergent composition and the surface to be adhered. , And excellent adhesion can be provided. In view of such special effects of the present invention, it is preferable that the gel detergent composition of the present invention is set so as to form a complicated shape on the surface to be adhered after being discharged from the container.

  An example of a complicated shape formed on the surface to be attached includes a shape having two or more convex portions. In the present specification, the shape of the gel detergent composition formed on the surface to be adhered is a shape as viewed from a direction perpendicular to the surface to be adhered.

  One mode of a shape having two or more convex portions is a rotationally symmetric shape having two or more radially extending convex portions and a concave portion formed between the convex portions. The rotational symmetry means that when rotated about a center point as an axis, even if the angle of rotation is less than 360 °, it matches the original shape. In the present invention, the rotationally symmetric shape is allowed to vary ± 20% from the complete rotational symmetry. In the rotationally symmetric shape, for example, a floral pattern, a star pattern, and the like can be formed.

  As a preferred example of the rotationally symmetric shape, the ratio (D1 / D2) of the distance D1 from the center C to the vertex T of the convex portion and the distance D2 from the center to one concave portion B adjacent to the convex portion is 1. 2 or more. FIG. 1 schematically shows the distances D1 and D2, taking an example of a rotationally symmetric shape having six radially extending convex portions and six concave portions formed between the convex portions. In the conventional gel detergent composition, even if the difference between the distances D1 and D2 is designed to be large in the rotationally symmetric shape, the shape cannot be maintained as designed, and the ratio (D1 / D2) is not satisfied. In the present invention, even when the rotationally symmetric shape is designed so that the difference between the distances D1 and D2 is large, the surface to be adhered is designed as designed. The ratio (D1 / D2) is large as in the above-mentioned range, and the shape of the convex portion can be emphasized.

  The ratio (D1 / D2) is preferably about 1.2 to 4, and more preferably about 1.about.4, from the viewpoint of providing an excellent appearance by making the shape of the convex part stand out as the rotationally symmetric shape and providing an excellent appearance. About 3 to 3.5 is mentioned.

  In the rotationally symmetric shape, when there are two or more convex portions having different sizes and the value of the ratio (D1 / D2) is two or more, at least one of the ratios (D1 / D2) is used. It is sufficient that the value is set so as to satisfy the above range.

  The distances D1 and D2 in the rotationally symmetric shape are appropriately set according to the type of the object to be cleaned and the like. If the object to be cleaned is a toilet bowl, for example, 1. 0 to 3.2 cm, preferably 1.2 to 3.0 cm, and more preferably 1.4 to 2.7 cm. As the distance D2, for example, 0.6 to 2.6 cm, preferably 0.7 to 1.4 cm, more preferably 1.0 to 1.3 cm.

  Note that, in the rotationally symmetric shape, when there are two or more convex portions having different sizes, and when the values of the distances D1 and D2 are each two or more, the value of at least one of the distances D1 and D2 is What is necessary is just to be set so that the range may be satisfied.

  The number of convex portions per one rotationally symmetric shape may be two or more, and may be appropriately set according to the pattern to be formed. For example, 2 to 10, preferably 3 to 8 And more preferably 4 to 6.

  In the rotationally symmetric shape, the shape of the convex portion is not particularly limited, and examples thereof include a petal shape, an elliptical shape, a circular shape, a teardrop shape, and a needle shape. When the shape of the convex portion is a petal shape, an elliptical shape, a circular shape, a teardrop shape, or the like, a floral pattern can be formed in the rotationally symmetric shape. In the rotationally symmetric shape, two or more convex portions may have the same size and shape, or may have different sizes or shapes.

  As another mode of the shape having two or more convex portions, a non-rotationally symmetric shape having two or more convex portions and a concave portion formed between the convex portions is given. In such a non-rotationally symmetric shape, for example, a heart pattern or the like can be formed.

  As a preferred example of the non-rotationally symmetrical shape, a vertical distance D3 from a straight line L connecting vertexes of two adjacent convex portions T to a concave portion B formed between the two convex portions is 1.2 cm or more. That are: FIG. 2 schematically shows the distance D3 by taking an example of a non-rotationally symmetric shape having two convex portions and one concave portion formed between the convex portions. In the conventional gel detergent composition, even if the distance D3 is designed to be large in a non-rotationally symmetric shape, the shape cannot be maintained as designed, the distance D3 becomes small, and the shape of the convex portion is reduced. According to the present invention, even if the distance D3 is designed to be large in a non-rotationally symmetrical shape, the shape can be formed on the surface to be adhered as designed, and the distance D3 can be reduced. It is possible to make the shape of the protruding portion stand out as large as the range of the projection.

  In the non-rotationally symmetrical shape, the distance D3 is preferably about 1.4 to 2.0 cm, more preferably 1.3 to 2.0, from the viewpoint of providing an excellent appearance by making the shape of the convex portion stand out. About 1.9 cm is mentioned.

  In addition, in the non-rotationally symmetric shape, when there are three or more protrusions and two or more distances D3, at least one value of the distance D3 is set so as to satisfy the range. Just do it.

  The number of protrusions per one non-rotationally symmetric shape may be two or more, and may be appropriately set according to the pattern to be formed. For example, 2 to 10, preferably 2 to 8, More preferably, 2 to 6 are mentioned.

  Further, the shape of the projection in one non-rotationally symmetric shape is not particularly limited, and examples thereof include a petal shape, an elliptical shape, a circular shape, a teardrop shape, and a needle shape. In the non-rotationally symmetric shape, the two or more protrusions may be of the same size and shape, or may be of different sizes or shapes.

The shape of the discharge port of the container for making the gel-like detergent composition after discharge into a desired shape is known in JP-A-2015-67321 and the like.

  In the gel detergent composition of the present invention, the amount of the gel detergent composition per one shape formed on the surface to be adhered after ejection is determined by the type of the object to be cleaned and the adhered on the surface to be adhered. It may be appropriately set according to the number and the like, and for example, about 2.4 to 4.0 g, preferably about 3.0 to 3.5 g.
