Description

[Detailed Description of the Invention] (Industrial field of application) The present invention mainly foams household cleaners and chemicals containing surfactants and applies them to the intended places such as wall surfaces, glass surfaces and screen doors. The present invention relates to a foam jetting container with an applicator.

(Prior Art) As a container with an applicator for applying a liquid material placed in an elastic container body to a target location by pressing the body of the container body and discharging it, for example, Japanese Utility Model Laid-Open No. 56-56748 ( (See FIG. 9), JP-A-61
-200875 (see FIG. 10), Japanese Utility Model Laid-Open No. 57-58461 (see FIG. 11) and the like are available.

The liquid material application container shown in FIG. 9 and FIG. 10 is equipped with an applicator 8 having an application part 9 such as a sponge-like porous material, a brush, a brush, etc. fixed to the surface thereof at the tip of the container body 1. The liquid material in the container body is supplied to the coating section 9 from the inside of the container body 1 to impregnate the coating section 9 with the liquid material, and the liquid material is coated by pressing and rubbing the coating section to a desired location. The liquid material coating container shown in FIG. 11 is provided with a liquid discharge hole 183 in the porous coating portion 9 and discharges the liquid material in the container body 1 through the pipe 7 connected to the liquid discharge hole 183. , Coating section 9
The liquid substance is applied by immersing the liquid substance in the substrate and pressing the coating portion 9 against the target portion and rubbing it.

(Problems to be solved by the invention) However, a conventional container with an applicator for applying a liquid substance in a container body 1 to a target location while discharging the liquid substance is a.) An application part 9 as shown in FIG. Liquid outlet 18 on sponge
In the case of a container with an applicator that has 3 opened, the pressing force for discharging the content liquid by pressing the body of the container body, even if it has been devised such as providing a liquid storage chamber to alleviate the discharge pressure. Depending on the degree of application of the liquid, the liquid material may be vigorously ejected from the liquid outlet 183 to contaminate the surface other than the target surface of the object to be coated, or the liquid material may adhere to the human body when the direction in which the coating portion 9 is directed is wrong. It also has the drawback of occurring. This means that the drain hole 18
It is the same even if bubbles are generated from 3 instead of liquid.

b.) As a means to prevent this jumping out, a method of impregnating a sponge with a liquid from the inside as shown in Figs. 9 and 10 has been proposed, but since the liquid substance is sent to the sponge surface through the small bubbles of the sponge, Since it is necessary to press the main body 1 with a strong force to apply a high pressure to the liquid material, there is a drawback that it requires a large amount of labor and that it is difficult to control the degree of impregnation into the sponge and that it is difficult to apply it uniformly to the surface of the object to be coated. is there.

Also, since the sponge is impregnated with a liquid substance, in the case of a liquid with a relatively low viscosity such as ordinary household cleaners, bleeding and dripping of the liquid from around the sponge cannot be avoided, and the container body and the user's hand cannot handle it. There is a drawback that the liquid is squeezed out from the sponge and drips even when the sponge is pressed against the surface of the object to be coated and applied.

The present invention solves the problems found in the conventional container with an applicator described above, that is, it is an easy-to-use application that does not drip, does not contaminate unnecessary parts or the user's hand, etc. It is an object of the present invention to provide a foam ejection container with a tool.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the foam ejection container with an applicator of the present invention, a container body having a body part that can be pressed and deformed and elastically restored, and the container body. A closure with a nozzle fitted to the mouth and neck of the container, a communication hole for fitting the nozzle of the closure from the inside, an air intake hole in the container body, and a communication of the foamable liquid. A gas-liquid mixing chamber having a liquid hole,
A pipe for passing an effervescent liquid hanging from a liquid passage hole of the gas-liquid mixing chamber, an intake check valve for sucking outside air into the container body provided in the closure, and a fitting provided in the closure. A foam jetting container with an applicator, comprising a coating part support base having a coating part selected from one or more of a porous material, a brush, and a brush on the surface of the coating part support base. An opening communicating with the inside of the nozzle is provided, and in front of the opening, the opening is tilted at a predetermined angle with respect to the ejection direction of the foam ejected from the opening to substantially cover the opening and eject the foam. The length and width in the direction perpendicular to the direction are erected from the coating section support base with a buffer plate for foam jetting pressure that is 4/5 or more of the length and width dimensions of the opening, and the coating section is
At least in the inclination direction of the buffer plate, and provided on the side facing the opening, the coating portion surface on that side at an angle within the range of -15 to +15 relative to the inclination angle of the buffer plate. A foam jetting container with an applicator, which is characterized in that the cushioning inclined surface is inclined.

(Operation) When the body portion of the container body is pressed and compressed, the inside of the container body is pressurized and the foamable liquid contained in the container body is supplied into the gas-liquid mixing chamber through the liquid passage pipe and the liquid passage hole. Here, the air is mixed with the air that has been press-fitted from the upper space of the container body through the air supply hole to form a bubble, which is ejected from the nozzle of the closure.

Most of the foam ejected from the nozzle, after passing through the opening, first collides with the buffer plate covering the opening to reduce the force of the ejection, and then on the buffer inclined surface facing the buffer plate. Since they collide with each other and the force of jetting is further reduced, they slowly move along the buffer slope as a whole, and rise and adhere to the surface of the coating part.

After that, when the pressing of the container body is stopped, a negative pressure is generated in the container body due to the restoring force of the container body, and the check valve for intake opens, so outside air passes through here and quickly enters the container body. Inhaled and quickly restored.

By continuously repeating the pressing and releasing of the pressure on the body of the container body, the content liquid can be continuously foamed and ejected.

After the bubbles have risen to the application section by such an operation, if the application section is pressed against the surface of the target coating section and moved, the foam becomes a cushion between the coating section and the surface of the coating section. , Can be spread over a wide area continuously with light force.

As a dimensional relationship between the buffer plate and the opening portion, the length and width of the buffer plate in the direction perpendicular to the jet direction of bubbles are set to be 4/5 or more of the length and width dimensions of the opening portion. If it is too small, the number of bubbles ejected from the opening that do not collide with the buffer plate will increase, and even if the bubbles connected to these collide with the buffer plate, the momentum of the ejection of all bubbles cannot be sufficiently reduced. Because.

Also, the angle of the buffer slope is set within the range of -15 to +15 with respect to the angle of the buffer plate if the angle of inclination of the buffer plate is less than -15 °. The bubble passage formed by the buffer sloped surface and the buffer sloped surface becomes too narrow, making it difficult to spray bubbles, while increasing the inclination angle of the buffer plate.
This is because if the angle is more than 15 °, the cushioning effect of the bubble ejection pressure becomes weak.

FIG. 4 is a perspective view of the closure with nozzle, and FIG. 4 is a cross-sectional view of a main part for explaining the movement of bubbles.

In the figure, 1 indicates a container body. This container body 1 has a body
It is a synthetic resin container that elastically deforms inward when 10 is pressed by hand, and elastically restores to its original shape when the pressure is released, and a screw portion is formed on the outer surface of the mouth / neck portion 2 at the upper end portion.

In addition, the foamable liquid A is stored in the upper part of the container body 1 in the upper part.
Accommodated in such a quantity that 13 is produced.

A ring cap 4 is screwed onto the mouth / neck portion 2.
The ring cap 4 has an outer cylinder wall 41 vertically extending from the peripheral edge of the zenith portion 40, and a screw portion which is screwed into the screw portion on the outer surface of the mouth / neck portion 2 is formed inside the outer cylinder wall 41. An annular protrusion 42 is formed inside the top portion 40.

A cylindrical nozzle 5 is fitted on the zenith portion 40.

In this embodiment, the ring cap 4 and the nozzle 5 form the nozzle-equipped closure 3.

The nozzle 5 is formed with a locking annular projection 51 that engages with the annular projection 42.

Further, on the outer surface of the upper portion of the nozzle 5, two locking projections 53 that engage with the mounting portion 81 of the applicator 8 are formed vertically.

Further, an inner cylinder wall 54 is vertically provided inside the nozzle 5.

A tubular gas-liquid mixing chamber 6 having a communication hole 61 at the upper end and a liquid passage hole 62 at the lower part is fitted to the inner cylinder wall 54 of the nozzle 5, and the lower part of the gas-liquid mixing chamber 6 is fitted. A pipe 7 for passing an effervescent liquid extending to a lower portion of the container body 1 is inserted, and an air supply hole 63 for taking in air in the container body 1 is formed between the pipe 7 and the gas-liquid mixing chamber 6. Has been done. And gas-liquid mixing chamber 6
A porous body 64 is sandwiched between the inner cylindrical wall 54 and the inner cylindrical wall 54.

In addition, a ball valve 65 that functions as a check valve is provided in the gas-liquid mixing chamber 6.
Is provided.

An intake hole 55 is formed on the lower side of the nozzle 5, and an intake check valve 58 including a ball valve 56, a spring 57 and a spring support 65 is formed inside the intake hole 55.

An applicator 8 is detachably fitted on the upper portion of the nozzle 5. The applicator 8 includes an applicator support base 81 to which an applicator 9 made of a porous material made of polyethylene foam is adhesively bonded, and two upper and lower ridges 53 into which the upper and lower ridges 53 of the nozzle 5 are respectively fitted. Nozzle 5 is formed by penetrating through a coating part support base 81 and a cylindrical mounting part 82 having a groove part 86 on the inner surface side.
A rectangular opening 83 is provided at the tip of the nozzle 5 so as to communicate with the inside of the nozzle 5, and a buffer plate 84 that covers the front of the opening 83 and reduces the force of bubble ejection pressure.

The coating section support base 81, the mounting section 82, and the buffer plate 84 are integrally molded of synthetic resin.

The cushioning plate 84 collides all or most of the bubbles ejected from the opening 83 and weakens the ejection pressure thereof, so that 30 to 60 degrees with respect to the ejection direction of the bubbles (direction of arrow C in FIG. 4). It is inclined at an angle of ° and has a length and width that can cover all or most of the opening 83 in front.

The angle of inclination of the buffer plate 84 is set to 30 ° to 60 ° because if it is smaller than 30 °, a long inclined surface is provided to cover most or all of the opening 83 (4/5 or more of the area of the opening 83). This is because it becomes a hindrance during application, and the function of dampening the force of foam ejection is weakened, while on the other hand, when it exceeds 60 °, the resistance when ejecting foam becomes too large. Because.

The cushioning plate 84 of the present embodiment is such that an angle of about 45 ° with respect to the bubble ejection direction from the opening 83 (the surface of the coating section support base 81) is provided on the support leg 85 that is erected from three sides around the opening 83. For about 135
The angle is °. ), And has a length and a width that cover almost all of the opening 83.

The coating section 9 joined to the coating section support base 81 is a buffer plate 84.
The side where the support legs 85 that support the opening do not surround the opening 83,
That is, the buffer plate 84 is provided only on the side facing the opening.
The structure has been cut out so that it has an inclined surface that has almost the same width as that of the buffer plate 84, and the inclined surface collides with the buffer plate 84, and the force of the ejection of bubbles that bounced back is further reduced. And the buffer inclined surface 91.

The buffer sloped surface 91 of the present embodiment has substantially the same inclination angle as the buffer plate 84, but this angle is the same as the inclination angle of the buffer plate 84 from the viewpoint of buffering the bubble jetting pressure and easiness of bubble jetting. Nainus
Range from 15 ° to plus 15 °.

A method of using the foam jetting container with the applicator will be described.

First, when the body portion 10 of the container body 1 is grasped with one hand and deformed by pressing from both sides, the volume of the container body 1 becomes smaller, the internal pressure increases, and the foamable liquid A rises in the pipe 7. Then, the ball valve 65 is pushed up and flows into the gas-liquid mixing chamber 6 through the liquid passage hole 62, while the air in the air reservoir 13 on the foamable liquid A also flows into the gas-liquid mixing chamber 6 through the gas supply hole 63. As a result, the two are mixed and foamed, and when they pass through the porous body 64, they become a fine and uniform foam, and are ejected from the communication hole 61 through the inside of the nozzle 5 through the opening 83.

The bubbles ejected from the opening 83 subsequently collide with the buffer plate 84 to reduce the momentum of the ejection and change the direction to change the direction of the buffer plate 84.
It collides with the buffer inclined surface 91 facing with.

The bubbles that have collided with the buffer inclined surface 91 have their momentum dampened by the collision, but further, because they receive frictional resistance when going up the buffer inclined surface 91 that is an uneven surface because it is formed of a porous material, , Its momentum weakens rapidly and adheres to the surface of the coating portion 9 and stops.

Next, when the pressing of the body 10 of the container body 1 is released, the restoring force of the body 10 of the container body restores the volume in the container body 1 to a negative pressure in the container body 1. The check valve 58 for intake is opened, and the outside air is rapidly sucked into the container body 1 through the intake hole 55.

At this time, the ball valve 65 in the gas-liquid mixing chamber 6 works to cause the liquid passage hole.
62 is closed.

When the body 10 is pressed again after the body 10 of the container body is restored, the bubbles whose jetting force has been reduced as described above slowly rises up the buffer inclined surface 91 and adheres to the surface of the coating portion 9.

If a suitable amount of bubbles accumulates on the surface of the coating section 9,
If the application part 9 is pressed against the surface of the object to be moved,
Since the foam acts as a cushion between the application part 9 and the object to be coated, it can be spread over a wide range with a light force.
Since the bubbles are only attached to the surface of the application part 9, no liquid drips at that time.

In the present embodiment, the force of the bubbles ejected from the opening 83 is weakened by the collision between the buffer plate 84 and the buffer inclined surface 91 and the friction between the buffer inclined surface 91 which is the uneven surface, so that the container body body 10 is strongly strengthened. Even when pressed, bubbles jump over the surface of the coating section 9 and scatter,
It does not adhere to parts other than the surface of the object to be coated, so if you accidentally press the container body 10 with the application part side facing you, bubbles will fly and adhere to the user's body. Since it does not occur, it is safe even when accommodating and applying a drug which is not particularly preferable to touch the human body.

Further, in this embodiment, the bubbles exiting the opening 83 only proceed on the surface of the inclined coating portion 9 made of the porous material, so that the contents liquid passes through the small bubbles of the porous material as shown in FIGS. Compared with the conventional container with an applicator shown, the pressing force on the body 10 of the container main body required for ejecting bubbles may be small, and since the intake port 55 with the check valve 58 is provided, the container The body 10 is quickly restored, and bubbles can be continuously sprayed and applied.

FIG. 5 is a perspective view of the applicator 8 of the second embodiment.

The buffer plates 84 of the applicator 8 are the applicator support base 81,
The opening 83, the buffer plate 84, and the support leg 85 have the same shape as that of the first embodiment, and only the application part 9 joined to the application part support base 81 surrounds the opening part 83 on three sides. Is different from the first embodiment. Then, the surface of the coating portion 9 on the side facing the opening 83 in the inclination direction of the buffer plate 84 is cut off so as to be an inclined surface having substantially the same width as the buffer plate 84 and an angle substantially the same as the buffer plate 84. The setting of 91 is the same as in the first embodiment.

The second embodiment is the same as the first embodiment except for the applicator 8.

In the second embodiment, the coating portion 9 surrounds the opening 83 on three sides. Therefore, as compared with the first embodiment, the coating portion area is wider by that amount, and there is an advantage that a large area can be coated quickly. .

FIG. 6 is a perspective view of the applicator 8 of the third embodiment.
The only difference from the embodiment is that the coating section 9 is composed of a porous material portion 92 and a brush (a bundle of bristles made of synthetic resin such as nylon or polyester) portion 93 surrounding the porous material portion 92.

Since the applicator 8 of the third embodiment is provided with the brush portion 93, it is suitable for rubbing a tiled or roughened wall surface or screen door to clean it.

FIGS. 7 to 8 show a fourth embodiment which is a modified example of the applicator 8, FIG. 7 is a front view of the applicator 8, and FIG. 8 is an X of FIG.
FIG. 4 is a vertical cross-sectional view of a part of the applicator 8 and the nozzle 5 cut by X-rays.

The applicator 8 of the fourth embodiment differs from the second embodiment only in the material of the applicator 9.

That is, in the second embodiment, a porous material obtained by foaming a synthetic resin or the like is used, but in this embodiment, instead of this, the coating section support base 8 is used.
The needle-shaped brush 9 is integrally formed with the mounting portion 82, the buffer plate 84, and the support leg 85.

The brush 94 is manufactured by injection molding a soft thermoplastic resin such as low density polyethylene in order to have elasticity.

In this example, the brush 94 on the side facing the opening 83 in the inclination direction of the buffer plate 84 is cut at the same width as the buffer plate 84 at the same angle as the inclination angle of the buffer plate 84, and the buffer inclined surface 91 is formed. Has been formed.

Also in the case of the foam spray container with an applicator equipped with the applicator 9 of the present example, the foam sprayed from the opening 83 collides with the buffer plate 84 to reduce the jetting force and change the direction, and the buffer sloped surface 91. Not only does it collide with each of the brushes 94 of FIG. 1 to further reduce the jetting force thereof, but also one brush at a time when climbing the buffer inclined surface 91.
Since it collides with the upper part of 94 and further weakens its momentum, it adheres to the brush 94 and stops.

Pressing and releasing the pressing of the container body 10 is repeated until a desired amount of bubbles are accumulated on the brush 94, and then the brush 94 is applied to the surface of the object to be rubbed to apply the bubbles to the surface of the object to be coated. To do.

In this example, since the application part 9 is formed by the brush 94, it is suitable for use when removing stains on screen doors and the like.

In the above embodiment, the supporting legs 85 for supporting the cushioning plate 84 are shown only when they are erected from three sides around the opening 83, but the present invention is not limited to this, and is shown in FIG. 2, for example. It may be erected only from the side (the side opposite to the buffer inclined surface 91). In this case, the shape of the coating portion 9 is set to the left and right sides of the opening 83 as in the example of FIG. 5 or FIG. It is preferable to prevent bubbles from scattering by forming a vertical wall of the coating section 9.

Moreover, since the applicator of the present invention is removable, the applicator can be used by changing it depending on the application.

(Effects of the Invention) The foam spray container with an applicator of the present invention is convenient because it can perform the two functions of a foam spray container and an applicator, and when the body of the container body is pressed to eject the foam. As bubbles always adhere to the surface of the application part and rise, the contents liquid squirts out farther than the surface of the application part like the conventional container with an applicator shown in FIG. It does not adhere to other objects to contaminate it or adhere to the human body. Furthermore, since the ejected bubbles only adhere to the surface of the application part, even if the application part is strongly pressed against the surface of the application part and rubbed. Thus, the effect that the container body, the user's hand, and the like are not polluted by dripping liquid is exerted.

Further, since the foam spray container with an applicator of the present invention has an intake hole with a check valve in a location other than the foam passage, foam contaminated by an object to be coated is restored when the body of the container is restored. There is an effect that the content liquid is not contaminated by being sucked into the interior and that the bubbles can be ejected quickly and continuously.
