2. Description of the Related Art As the foam jetting container, for example, a container disclosed in Japanese Examined Patent Publication No. 52-16567 is known. The container is a container body in which a cap screwing mouth and neck is erected from the upper end of a body that can be elastically squeezed, and an outward flange is engaged with the upper surface of the mouth and neck to form a funnel-shaped upper part in the mouth and neck. A foam member in which a ball valve-containing valve chamber portion is provided, a liquid pipe is hung from the lower end of the valve chamber portion into the container body, and a funnel-shaped opening surface of the valve chamber portion is closed by a foaming net-like member; A cap with a nozzle fitted to the valve chamber, and an air hole is formed in the upper part of the peripheral wall of the valve chamber, and when the container body is squeezed, the liquid extruded through the liquid pipe and the air hole are passed through. The air above the liquid level in the container that is extruded is mixed in the upper part of the valve chamber part, and when it passes through the net-like member together, it is foamed and ejected from the nozzle, and when the squeezing of the body part is released. Outside air flows into the container body through the nozzle, net-shaped member, and air hole, It is provided to sexual restored.

By the way, when the bubbles are continuously ejected, it is necessary to quickly elastically restore the body of the container. However, in the container, an air hole for mixing with the liquid at the time of foaming is required. And, since the same air hole is also used as the air hole for outside air suction at the time of elastic restoration of the trunk, if the above-mentioned air hole is made large in order to increase the outside air suction amount for trunk elastic restoration, The amount of air for liquid mixing at the time of elastic pressing of the body also becomes large, and the size of the foamed foam becomes non-uniform, so that there is a drawback that a dense and uniform foam cannot be obtained.

As a container that does not have the above-mentioned drawbacks,
There is container No. 27558. The container is provided with a horizontal plate on the inner surface of the upper part of the cap fitted with a nozzle fitted to the neck of the container body, a pipe fitting cylinder is provided from the peripheral edge of the opening at the center of the horizontal plate, and a liquid is supplied from the inside of the cylinder.

The upper air is discharged through the air hole, and the outside air suction for elastic recovery of the body is provided through the liquid pipe into the container body.

However, in the case of the container, since the air that has entered the container body through the liquid pipe floats above the liquid surface through the liquid in the container body, many bubbles are formed above the liquid surface. Therefore, when the container body is transparent, bubbles in the container body are visible, which is not preferable in appearance.

According to the present invention, an outside air income port by a check valve is provided in addition to the air discharge port for foaming to make the jetted bubbles uniform, and the suction port is formed by a check valve which can be widely opened.
The first purpose of the elastic recovery of the body is to shorten the time required for elastic recovery by a large amount of intake air to enable continuous squeezing, and to always prevent the liquid leakage when the container is overturned by closing the container. Further, in addition to the above-mentioned purpose, a foaming cylinder is provided and a base end portion and a tip end portion thereof are provided so that the foaming air and the liquid are mixed and foamed more reliably to obtain a dense and uniform foam. Is to have a double foaming and regulating net,
Further, in addition to the first object, a plurality of elastic pieces are hung from the valve body corresponding portion of the check valve for the outside air suction port, and the valve body of the check valve for liquid outflow is attached to the lower ends of these elastic pieces. Thus, the two check valves can be easily molded, and the two check valves can be reliably closed to prevent liquid leakage when the container falls.

[0025]

Since the present invention has been described above, it has the following effects in common with all claims.

Since the foaming air discharge port and the outside air suction port are separately provided and the outside air suction port is formed by the outside air suction valve 44, it is normally closed to prevent liquid leakage when the container falls, and at the same time, the body elastic. At the time of restoration, a large hole is opened and the elastic restoration can be shortened by a large amount of air intake to continuously perform bubble ejection operation. Also, the foaming air discharge port is made to have a proper cross-sectional area, and the bubbles to be discharged are coarse. In addition, since the outside air sucked into the container body does not pass through the liquid pipe and directly enters the space above the liquid surface in the container body, many bubbles may occur on the liquid surface. The outside air suction port is held by fitting the lower surface of the first mouth portion 11 formed by opening the central portion of the first top wall 10 of the plug-like member to the inner surface of the short tube 26 of the liquid delivery member 25. Cylinder
41 Elastic strips 42 are projected from a plurality of points on the inner surface of the upper end and are formed by an outside air intake valve 44 formed by closing the upper surface of an inverted dish-shaped portion 43 attached to the tip of the elastic strip 42, so that the elastic recovery of the body of the container The outside air suction passage is always closed except when the outside air is sucked in, and since the liquid pipe has a small diameter, liquid cannot flow out through the pipe unless the container body is squeezed. In addition, the foaming air discharge passage can discharge pressurized air, but its cross-sectional area can be reduced to the extent that liquid does not pass therethrough, so that liquid leakage when the container falls down can be prevented.

In the case of claim 2, in addition to the above effect, since the upper end surface of the foaming cylinder 52 is closed by the foam adjusting net 53, the foam to be discharged can be made dense and uniform. It is convenient and can enhance the appearance.

According to the third aspect of the invention, the elastic strips 42 project in the circumferential direction from a plurality of positions on the upper end of the inner surface of the holding cylinder 41 to hold the reverse dish-like portion 43 at the tip thereof, and the upper plate of the reverse dish-like portion. A plurality of second elastic strips 55 are vertically provided from the periphery of the second opening 47 formed by opening the central portion, and the valve body 56 attached to the lower end of the second elastic strips 55 is used to form the valve at the inner bottom of the funnel-shaped valve chamber portion 30. Since the hole is closed to form the discharge valve 35, the discharge valve valve body and the reverse plate-shaped portion as the valve body of the outside air suction valve
43 and 43 can be molded together as a part of the foam member 40, which facilitates the molding and also enables the upper and lower elastic strips 42,
Since the reverse dish-shaped portion 43 is supported by 42, the elastic strips of these can be thinned to enhance the elasticity, and thus the opening and closing of both check valves can be ensured. The valve body 56 of the discharge valve does not roll like a ball valve even when the container falls, so that the liquid leakage can be prevented more reliably when the container falls.
