2. Description of the Related Art A trigger type sprayer that sprays or sprays a liquid composition such as a finishing liquid, a fungicide, a disinfectant, a bleach, or the like by triggering (gripping / loosening) a lever has been widely used. Such a trigger-type sprayer generally includes a container in which a liquid is stored, and a trigger spray member mounted on an upper portion of the container, and the trigger spray member includes a liquid sending tube for sending the liquid. The liquid in the container is supplied to a nozzle provided with a discharge portion of the trigger spray member, and is sprayed or ejected from the nozzle.

[0003] In order to impart a change to the spray pattern, there have been proposed many sprayers in which nozzles are modified. Among them, many proposals have been made for a foam discharge container provided with a so-called foaming nozzle for discharging the content liquid in a foam form in order to improve the fixability of the liquid to the spray target.

[0004]

However, in the case of a foaming nozzle, a method is known in which a liquid sprayed in the form of mist collides with a foaming cylinder to foam the liquid. Since it is concentrated and sprayed, it is difficult to obtain a wide pattern, and there is a problem that the foam is thickly applied to the object and the effect of the inner solution cannot be sufficiently exerted.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. Spraying in the form of a foam, widening the spray pattern, improving the spraying efficiency of the content liquid, and spraying the foam thinly. Accordingly, an object of the present invention is to provide a foam discharge container capable of efficiently using a content liquid.

According to the present invention, there is provided a container body for storing a liquid, and a trigger spray member attached to the container body for ejecting the liquid in the container body. The spray member includes a foaming member that is formed in a cylindrical shape and protrudes around an ejection hole of a nozzle from which the droplet is ejected, and the droplet ejected from the ejection hole collides with an inner wall of the foaming member. In the foam discharge container which is foamed and jetted, a cutout is formed at least in a part of an inner surface near a front end of the foaming member.

It is preferable that the notch penetrates the inside and outside of the foaming member so that the foam can be effectively and widely sprayed. In addition, it is preferable that the cutout portion is opened from the injection hole side of the foaming member toward the distal end portion so that the foam can be effectively and widely foamed.

According to the present invention, most of the droplets sprayed in the form of a mist from the nozzle fall on the inside of the cylindrical foaming member, bounce off and mix with the air to form a foam. As the other part passes through the notch formed at least in part of the inner surface near the tip of the foaming member, the air is entrained and foamed and is sprayed outward and sprayed. , Can be spread over a wide area without being concentrated in the center.

Further, by forming the cutout portion from the inside to the outside of the foaming member, a part of the droplet discharged from the nozzle penetrates through the tubular foaming member and becomes wider outside. And spread very widely.

Further, since the cutout portion is opened from the injection hole side of the foaming member toward the tip end portion, the foamed droplets are continuously and uniformly spread from the central portion to the outside. can do.

Detailed plan view of the nozzle,
(B) is a detailed side sectional view, FIG. 4 is an explanatory view showing a normal spray pattern by the nozzle, FIG. 5 is an explanatory view showing a spray pattern sprayed from a slit of the nozzle, and FIG. FIG. 4 is an explanatory plan view showing a spray pattern of FIG.

The foam discharge container 1 according to the present embodiment is a trigger type sprayer as shown in FIG. 1, and a dispenser 3 is attached to a mouth 2a of a container 2 containing a liquid to be sprayed by a cap 4. It is installed. A nozzle 5 is provided at a front end of the dispenser 3, and a trigger 6 is swingably provided behind the nozzle 5 with a gap between the trigger 4 and the cap 4. A piston 7 and a cylinder 8 are arranged adjacent to the trigger 6. By swinging the trigger 6, the piston 7 moves forward and backward within the cylinder 8 in conjunction with the trigger 6. As a result, the volume in the cylinder chamber 8a is reduced and increased.

The dispenser 3 is configured such that a valve portion 9 is provided adjacent to the cylinder chamber 8a, and a stainless steel ball 10 is provided below the valve portion 9 on the seat surface 9a.
A dip tube 11 is connected below the seating surface 9a to allow the liquid to flow from the container 2 to the dispenser 3. In the upper part of the valve section 9, a passage hole 12 to the cylinder chamber 8a and the normal valve body 1 are formed.
3a is pressed against the seating surface 9b by the urging force, and the valve body 13a is
b, the upper valve 13 that opens apart from the
A nozzle passage 5a extending to the nozzle 5 at the tip end is formed. The lower portion of the valve body 13a extends near the ball 10, and serves as a regulating member for operating the ball 10 within a certain range.
