Description

  The present invention relates to a hard surface cleaning article.

As is well known, a spray container (trigger spray container) with a trigger sprayer attached to the mouth of the container body pulls the trigger, discharges the air inside the cylinder, and returns the trigger. When the liquid is sucked up through a tube immersed in the liquid, the liquid is filled in the cylinder, the trigger is pulled again, and the liquid in the cylinder is pushed out and led to a vertical pipe. There is a type in which a spin is given to the flow of a liquid material through a path and a spin element, and finally ejected from a nozzle.
Such trigger-type spray containers are used as containers for various liquid substances such as detergents such as tableware, bathtubs and window glass, and mold removal agents, and are intended to contain cleaning compositions and mold removal agents. In order to prevent dripping from the object to be cleaned and to increase the cleaning effect by extending the time to stay on the object to be cleaned, the cleaning composition contained inside is mixed with air to make bubbles. What sprays is also known (refer to patent documents 1).

By the way, as an article for washing a bathtub used for washing a bathtub, a spray container and a liquid detergent composition contained in the spray container are provided. Has been proposed.
However, dirt that is firmly adhered to the object to be cleaned, for example, oil dirt that adheres to the tableware, may not be sufficiently cleaned by a cleaning method that does not apply mechanical force as described above.

JP-A-8-198301

  As described above, when the cleaning method that does not apply mechanical force cannot be sufficiently cleaned, for example, when cleaning oil stains firmly attached to the dishes, the dishes are immersed in a dishwashing water bath. A cleaning method using a hot water of about 40 ° C. to 45 ° C. or a device such as washing twice is used. However, even if such a contrivance is not required, if a sufficient cleaning effect can be obtained only by washing without applying mechanical force as much as possible, it is possible to reduce the labor of housework and reduce the amount of water consumption.

  The subject of this invention is related with providing the articles | goods for hard surface cleaning which can improve the cleaning effect by a liquid cleaning composition.

  The present invention relates to an article for hard surface cleaning comprising a trigger type spray container and a liquid detergent composition contained in the spray container, wherein the spray container foams the liquid detergent composition. It is possible to provide a hard surface cleaning article that can be sprayed and has a foam specific volume of 15 mL / g or more.

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

It is a sectional side view which shows the principal part of the spray container in one Embodiment of the articles | goods for hard surface cleaning of this invention. It is a figure which shows the state which looked at the spin element of the spray container shown in FIG. 1 from the front end side. The tip of the spin element is the side close to the nozzle part that projects bubbles out of both ends in the axial direction of the spin element.

Hereinafter, the present invention will be described based on preferred embodiments thereof.
The hard surface cleaning article of the present embodiment includes a trigger spray container 1 and a liquid cleaning composition (not shown) accommodated in the spray container.
The spray container used in the present invention is a trigger type spray container. The trigger type spray container, like the spray container 1 shown in FIG. 1, is a trigger type that ejects the liquid material to the mouth of the bottomed container body 2 filled with the liquid material that is the liquid detergent composition. The sprayer 3 is mounted, and generally, the trigger 4 is pulled, the air in the cylinder 9 is discharged to the outside, and when the trigger 4 is returned, the tube 7 is immersed in a liquid material. The liquid material is sucked up, the liquid material is filled in the cylinder 9, and the trigger 4 is pulled again to push out the liquid material in the cylinder 9 and lead it to the vertical pipe 6, and further through the horizontal pipe 8 and the spin element 10. 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. The spray container 1 is configured such that the liquid material is placed in the mouth of the bottomed container body 2 filled with the liquid material. The spray type sprayer 3 to be ejected has a configuration in which it is detachable or non-detachable by screwing or the like. The sprayer 3 is mainly composed of a sprayer main body 5 that pulls the trigger 4 and ejects the liquid material filled in the container main body 2. The sprayer main body 5 includes a vertical pipe 6 and A horizontal line 8 communicating with the vertical line 6 is formed. A cylindrical wall portion 91 that constitutes the cylinder 9 is formed at a position below the horizontal conduit 8, and a piston member 92 that slides inside the cylinder 9 is disposed. The trigger 4 that presses the piston member 92 is rotatably fitted to the side wall of the sprayer body 5. A small circle 41 indicated by a one-dot chain line in FIG. 1 indicates the position of the rotation axis of the trigger 4 provided on the side wall portion of the sprayer body 5. The trigger 4 is always urged in a direction away from the mouth of the container body 2 by urging means (not shown) such as a leaf spring and a coil spring.
In the present specification, the upper and lower directions are upward or downward 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 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. The stop valve 94 allows the liquid material to flow into the flow channel on the horizontal pipe line 8 side, while preventing the liquid material from returning from the flow channel when the trigger 4 is returned.
As shown in FIG. 2, the spin element 10 has a plurality of groove portions 10a extending in the axial direction around the spin element 10. The tip part arranged on the nozzle part 11 side has a cylindrical concave part 10b and a groove part 10c that connects the concave part 10b and each groove part 10a. Since the groove 10c is connected to a location shifted from the center of the recess 10b, a spin is given to the flow of the liquid in the recess 10b, and the spin-applied liquid is applied to the tip 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 disposed in the vicinity. 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, there is an inner opening on the back side of the liquid material sprayed in a conical shape, and an outer opening is formed at the tip of the injection port forming member 11a. A hole or groove 11d is formed. When the air taken in through the air intake holes or grooves 11d is mixed with the liquid material to be sprayed in a conical shape, the cleaning composition as a liquid material becomes bubbles and is jetted from the bubble discharge port 11e. Is done.

The sprayer 3 of the spray container 1 shown in FIG. 1 is a pressure accumulation type sprayer. The pressure accumulation type sprayer means that even when the trigger 4 is operated, the liquid material in the cylinder 9 is not ejected until the liquid pressure in the cylinder 9 reaches a predetermined liquid pressure. When the pressure is increased to a predetermined fluid pressure or higher, a liquid material is ejected.
The sprayer 3 shown in FIG. 1 includes a pressure accumulating member 12 in order to cause injection only when the pressure in the cylinder 9 is increased to a predetermined hydraulic pressure or higher. The pressure accumulating member 12 includes a cylinder 13 having a cylindrical inner wall surface, and a valve member 14 that is disposed in the cylinder 13 and moves up and down along the central axis of the cylinder 13. The valve member 14 is constantly biased upward by a biasing means 15 such as a coil spring, and when the trigger 4 is not operated, as shown in FIG. 1, a plug formed on the upper end of the valve member 14. 14a has closed the outflow port 13a to a 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 cylindrical portion 14c is continuously provided on the lower surface of the plunger portion 14b. . A flow path 14a ′ for a liquid flowing from the small diameter cylindrical portion 14c to the periphery of the plug body 14a is formed at the lower end of the plug body 14a.

When the trigger 4 is operated while the liquid material is filled in the cylinder 9, 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 fed into the pressure accumulating member 12 from the liquid inlet 13b. Thereby, the liquid pressure of the liquid substance existing in the cylinder 13 increases. 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 difference in area, the liquid pressure of the liquid material acts as a force for pushing down the valve member 14. When the operation of continuously pulling the trigger 4 is continued, the hydraulic pressure in the cylinder 9 and the cylinder 13 further increases, and the force for pushing down the valve member 14 becomes larger than the force for pushing up the biasing means 15. As a result, the valve member 14 is lowered, the outlet 13a closed by the plug 14a is opened, and the liquid material is discharged from the nozzle portion 11.
On the other hand, when the trigger 4 is pulled to the final position, the hydraulic pressure in the cylinder 9 and the cylinder 13 decreases, and the force for pushing down the valve member 14 becomes smaller than the pushing force of the urging means 15. The outlet 13a is closed again by the plug body 14a.

As the spray container provided with the pressure accumulation type sprayer, the above-described spray container 1 can be used. However, the spray container 1 is not limited thereto, and various known ones can be used. For example, those described in JP-A-9-122547, JP-A-9-308843, and JP-A-10-174911 can be used. Among the known pressure-accumulating sprayers that spray a liquid material in the form of a mist, the nozzle portion is replaced with a nozzle portion that can discharge bubbles. As the nozzle part capable of discharging foam, the nozzle part 11 of the spray container 1 described above, the one shown in FIG. 1 of Japanese Patent Application Laid-Open No. 2004-290943, the one shown in FIG. 2 of Japanese Patent Application Laid-Open No. 2007-167719, etc. Can also be used.
