Description

The present invention relates to articles for hard surface cleaning.

As is well known, in a spray container (trigger type spray container) in which a trigger type sprayer is attached to the mouth of the container body, a trigger is pulled to exhaust the air in the cylinder to the outside and return the trigger. At that time, the liquid material is sucked up through a tube immersed in the liquid material, the cylinder is filled with the liquid material, and the trigger is pulled again to push out the liquid material in the cylinder and guide it to the vertical pipeline, and further to the horizontal pipe. There is a type that gives spin to the flow of liquid material through the path and spin element, and finally ejects from the nozzle.
Such a trigger type spray container is used as a container for detergents such as tableware, bathtubs, window glass, and various liquid substances such as a mold remover, and is used to store a cleaning agent composition and a mold remover. Is to mix the cleaning agent composition contained inside with air to form bubbles from the viewpoints of preventing dripping from the object to be cleaned and extending the time it stays on the object to be cleaned to enhance the cleaning effect. Some are also known to be sprayed (see Patent Document 1).

By the way, as a bathtub cleaning article used for cleaning a bathtub, a spray container and a liquid cleaning agent composition contained in the spray container are provided, and the bathtub can be directly sprayed and then washed away. Has been proposed.
However, stains that are firmly stuck to the object to be cleaned, for example, oil stains that are stuck to the tableware, may not be sufficiently cleaned by the cleaning method that does not apply mechanical force as described above.

Japanese Unexamined Patent Publication No. 8-198301

As described above, when the washing method without applying mechanical force cannot sufficiently wash the dishes, for example, when washing the oil stains firmly attached to the dishes, the dishes are immersed in a dish detergent water bath. A washing method devised such as using hot water of about 40 ° C. to 45 ° C. or washing twice is used. However, even without such a device, if a sufficient cleaning effect can be obtained only by cleaning with as little mechanical force as possible, it is possible to reduce the labor of housework and the amount of water consumed.

An object of the present invention is to provide a hard surface cleaning article capable of enhancing the cleaning effect of the liquid cleaning agent composition.

The present invention is a hard surface cleaning article composed of a trigger type spray container and a liquid cleaning agent composition contained in the spray container, wherein the spray container foams the liquid cleaning agent composition. To provide a hard surface cleaning article that can be sprayed and has a foam specificity of 15 mL / g or more.

According to the article for hard surface cleaning of the present invention, the cleaning effect of the liquid cleaning agent composition can be enhanced, and for example, the cleaning effect of cleaning without applying mechanical force can be significantly improved.

It is a side sectional view which shows the main part of the spray container in one Embodiment of the article for hard surface cleaning of this invention. It is a figure which shows the state which the spin element of the spray container shown in FIG. 1 is seen from the tip side. The tip of the spin element is the side of both ends of the spin element in the axial direction closer to the nozzle portion where bubbles are projected.

Hereinafter, the present invention will be described based on the preferred embodiment thereof.
The article for hard surface cleaning of the present embodiment includes a trigger type spray container 1 and a liquid cleaning agent composition (not shown) contained in the spray container.
The spray container used in the present invention is a trigger type spray container. Like the spray container 1 shown in FIG. 1, the trigger type spray container is a trigger type that ejects the liquid substance into the mouth of a bottomed container body 2 filled with a liquid substance which is a liquid cleaning agent composition. In general, the trigger 4 is pulled to expel the air in the cylinder 9 to the outside, and when the trigger 4 is returned, the tube 7 is immersed in a liquid material. By sucking up the liquid material, filling the cylinder 9 with the liquid material, and pulling the trigger 4 again, the liquid material in the cylinder 9 is pushed out and guided to the vertical pipeline 6, and further through the horizontal conduit 8 and the spin element 10. A spin is given to the flow of the liquid material, and the liquid material is ejected from the nozzle portion 11.

A more specific configuration of the spray container used in the present embodiment will be described with reference to FIG. 1. In the spray container 1, a liquid substance is placed in the mouth of a bottomed container body 2 filled with a liquid substance. The ejecting trigger type sprayer 3 has a configuration in which the sprayer 3 is attached to be detachable or non-detachable by screwing or the like. The sprayer 3 is mainly composed of a sprayer body 5 that pulls a trigger 4 to eject a liquid material filled in the container body 2, and the vertical pipeline 6 and a vertical pipeline 6 and the sprayer body 5 are contained in the sprayer body 5. A horizontal pipeline 8 communicating with the vertical pipeline 6 is formed. A tubular wall portion 91 constituting the cylinder 9 is formed at a lower position of the horizontal pipeline 8, and a piston member 92 sliding in the cylinder 9 is arranged. Then, the trigger 4 that presses the piston member 92 is rotatably fitted to the side wall portion of the sprayer body 5. The small circle 41 shown by the alternate long and short dash line in FIG. 1 indicates the position of the rotation axis of the trigger 4 provided on the side wall of the sprayer body 5. Further, the trigger 4 is constantly urged in a direction away from the mouth of the container body 2 by an urging means (not shown) such as a leaf spring or a coil spring.
In the present specification, the upper side and the lower side are the upper side or the lower side in the vertical direction when the spray container 1 is placed on a horizontal plane.

The cylinder 9 has a first check valve 93 and a second check valve 94. The first check valve 93 allows the inflow of the liquid material from the flow path on the tube 7 side, while preventing the liquid material from returning to the flow path when the trigger 4 is pulled, and the second reverse check valve 93. The stop valve 94 allows the liquid material to flow out to the flow path on the horizontal pipeline 8 side, while preventing the liquid material from returning from the flow path when the trigger 4 is returned.
The spin element 10 has a columnar shape, and as shown in FIG. 2, has a plurality of groove portions 10a extending in the axial direction around the spin element 10. The tip portion arranged on the nozzle portion 11 side has a columnar recess 10b and a groove portion 10c connecting the recess 10b and each groove portion 10a. Since the groove portion 10c is connected to a position deviated from the center of the recess 10b, spin is given to the flow of the liquid substance in the recess 10b, and the spin-given liquid substance is sent to the tip portion of the spin element 10. It is injected in a conical shape from the injection port 11b provided in the injection port forming member 11a arranged close to each other. The injection port forming member 11a forms the nozzle portion 11 together with the former member 11c attached to the tip portion thereof. Between the former member 11c and the injection port forming member 11a, an inner opening is provided on the back side of the liquid material to be injected in a conical shape, and an outer opening is provided at the tip of the injection port forming member 11a for air intake. A hole or groove 11d is formed. When the air taken in through the air intake hole or groove 11d is mixed with the liquid material injected in a conical shape, the cleaning agent composition as the liquid material becomes bubbles and is injected from the bubble discharge port 11e. Will be done.

The sprayer 3 of the spray container 1 shown in FIG. 1 is an accumulator type sprayer. With the accumulator type sprayer, even if the trigger 4 is operated, liquid matter is not ejected from the nozzle portion 11 until the hydraulic pressure in the cylinder 9 reaches a predetermined hydraulic pressure, and the hydraulic pressure in the cylinder 9 is not generated. There when elevated to a predetermined liquid on pressure or, in which liquid material is configured to be injected.
The sprayer 3 shown in FIG. 1 is provided with a pressure accumulating member 12 so that injection occurs only when the pressure in the cylinder 9 is increased to a predetermined hydraulic pressure or higher. Accumulator member 12 comprises a cylinder 13 having a cylindrical inner wall, disposed within the cylinder 13, that has a valve member 14 that moves up and down along the central axis of the cylinder 13. The valve member 14 is always urged upward by a urging means 15 such as a coil spring, and when the trigger 4 is not operated, a plug formed at the upper end of the valve member 14 as shown in FIG. 14a closes the outlet 13a to the downstream flow path. A plunger portion 14b whose outer peripheral portion is in sliding contact with the inner wall surface of the cylinder 13 is continuously provided below the plug body 14a, and a small-diameter tubular portion 14c is continuously provided on the lower surface of the plunger portion 14b. .. At the lower end of the plug body 14a, a flow path 14a'of a liquid flowing from the small-diameter tubular portion 14c to the periphery of the plug body 14a is formed.

When the trigger 4 is operated while the cylinder 9 is filled with a liquid substance, the first check valve 93 is closed and the second check valve 94 is opened, so that the liquid in the cylinder 9 is liquid. An object is sent into the accumulator member 12 from the liquid inlet 13b. As a result, the hydraulic pressure of the liquid material existing in the cylinder 13 rises. The area of the upper surface of the plunger portion 14b is larger than the area of the lower surface of the plug body 14a, and due to the area difference, the hydraulic pressure of the liquid substance acts as a force for pushing down the valve member 14. When the operation of pulling the trigger 4 is continued, the hydraulic pressure in the cylinder 9 and the cylinder 13 is further increased, and the force pushing down the valve member 14 becomes larger than the pushing force of the urging means 15. As a result, the valve member 14 is lowered, the outlet 13a closed by the plug body 14a is opened, and the liquid material is discharged from the nozzle portion 11.
On the other hand, when the trigger 4 is completely pulled to the final position, the hydraulic pressure in the cylinder 9 and the cylinder 13 decreases, and the force pushing down the valve member 14 becomes smaller than the pushing force of the urging means 15, so that the valve member 14 becomes It rises and the outlet 13a is closed again by the plug 14a.
