Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a manual liquid ejection container such as an atomizer, a foamer, or a dispensing device that directly ejects a suitable amount of liquid through a nozzle.

"Prior Art" The conventional container described above includes a container body, a cylinder that is vertically disposed inside the container body by engaging an outward flange on the upper outer surface of the container body, and an upper end surface of the mouth and neck of the container body. a mounting cylinder in which a facing flange is held between the top surface of the mouth of the container by an inward flange at the upper end of the peripheral wall, and the peripheral wall is screwed to the outer surface of the mouth and neck; The actuating member has a piston fitted therein and a head with a nozzle fitted to the upper end of a stem that stands up from the cylindrical piston, and a coil spring that urges the actuating member upward. Furthermore, it was formed by a combination of two or more members.

``Problems to be Solved by the Invention'' The conventional container described above has the disadvantage of high cost due to the large number of components.

The present invention eliminates the above drawbacks and reduces the number of members.

"Means for Solving the Problems" A container body 1 with a mouth and neck part 2 erected upward, and a peripheral wall 4 fitted to the mouth and neck part of the container body are suspended from a first top wall 5, A suction valve 7 is provided in a first cylindrical portion 6 that hangs down from the opening periphery at the center of the first top wall 5, and a liquid suction pipe 8 is provided vertically from the first cylindrical portion into the container body. A cap-shaped member 3 in which a cylinder 12 stands up from the wall 5 surrounding the opening, and a second cylindrical part 1 that is movable up and down into the cylinder.
5, a cylindrical piston 16 is fitted to the lower end of the second cylindrical portion 15, and a liquid through hole opening inside and outside the second cylindrical portion is provided on the outer periphery of the second top wall 17 that closes the upper surface of the second cylindrical portion. 18..., and a tapered inverted skirt portion 19 that expands upward and outward from the second top wall portion on the center side of the liquid through hole, respectively. a coil spring 22 that urges the valve member upward; and the second cylindrical portion 15.
The upper part of the inverted skirt part 19 is fitted into the third cylindrical part 25 hanging from the back surface of the third top wall 17, and the upper end of the inverted skirt part 19 is brought into watertight pressure contact with the inner surface of the third cylindrical part 25 to open the discharge valve 26. A liquid ejection container was formed with a push-down head 23 having a nozzle 27 attached to the third top wall 24 and communicating with the ejection valve.

"Operation" When the head 23 is pushed down from the state shown in Figure 1,
Since the suction valve 7 is closed, the discharge valve 26 is opened and the liquid in the cylinder 12 is discharged through the discharge valve and the nozzle 27. When the head is released from the depressed state, the discharge valve 26 closes due to the negative pressure created by the head rising, and the suction valve 7 opens, and the liquid is sucked into the cylinder inside the container through the suction pipe 8.

"Example" 1 is a container body with a mouth and neck part 2 erected upward.

A peripheral wall 4 of a cap-like member 3 is screwed into the mouth and neck portion. The cap-like member has a first top wall 5
The peripheral wall 4 is suspended from the periphery, and the first top wall is opened at the center, and the first cylindrical portion 6 is suspended from the periphery of the opening. A suction valve 7 is provided within the first cylindrical portion, and a liquid suction pipe 8 is provided vertically from the first cylindrical portion into the container body. The suction valve 7 has a downwardly small diameter tapered inward flange attached to the inner surface of the first cylindrical portion to form a valve seat 9, and a ball valve 10 is placed on the valve seat.
There is also a protrusion 11 above the ball valve to prevent the ball valve from being pulled out.
is attached.

The cap-like member also makes the cylinder 12 stand up from the upper surface of the first top wall 5, surrounding the aforementioned opening. The engagement cylinder 13 may be made to stand up from the upper surface of the first top wall with a small gap between it and the cylinder. A thread is provided on the outer surface of the upper end of the engaging cylinder.

Reference numeral 14 denotes a valve member with a piston, and a cylindrical piston 16 is attached to the outer periphery of the lower end of the second cylindrical portion 15, and is fitted into the cylinder so as to be vertically movable. The second top wall 17, which closes the upper surface of the second cylindrical portion, has a second
A liquid through hole 18 that opens inside and outside the cylinder portion is provided, and a second top wall 17 located closer to the center than the through hole is provided.
A tapered inverted skirt portion 19 that expands upward and outward is erected from the portion. A large diameter rod portion 20 is seen from the back surface of the second top wall with a gap between it and the second cylinder portion.
is installed vertically, and a ball valve presser rod 21 is installed vertically from the center of the lower end of the rod. As shown in FIG. 2, when the valve member with a piston is pushed down to its lower limit, the presser rod contacts the ball valve 10 and presses the ball valve against the valve seat 9 to prevent the suction valve 7 from opening.

Reference numeral 22 denotes a coil spring that urges the piston-equipped valve member 14 upward;
It is interposed between it and 7.

The push-down head 23 has a third cylindrical part 25 hanging from the back surface of the third top wall 24, and the upper part of the second cylindrical part 15 of the piston-equipped valve member 14 is fitted into the third cylindrical part. A discharge valve 26 is formed by bringing the upper end of the inverted skirt portion 19 into pressure contact with the inner surface of the third cylindrical portion 25 in a watertight manner. Furthermore, a nozzle 27 communicating with the discharge valve
is attached to the third top wall 24. Third top wall 24
It is preferable that the fourth cylindrical portion 28, which is fitted to the outer surface of the cylinder in a vertically movable manner, hangs down from the back surface. When the aforementioned engagement tube 13 is made to stand up from the first top wall of the cap-like member, the fourth tube portion 28 is inserted between the engagement tube 13 and the cylinder 12. An engagement protrusion 29 is provided around the outer periphery of the lower end of the fourth cylindrical portion 28, and is prevented from being pulled out of the push-down head by engaging with the engagement protrusion 13a on the inner periphery of the upper end of the engagement cylinder. However, a protrusion for preventing extraction may be provided on the outer periphery of the upper end of the cylinder and the inner periphery of the lower end of the fourth cylindrical portion. In the illustrated example, the third
A short screw cylinder 30 is provided hanging from the back surface of the top wall, and the upper end of the engagement cylinder 13 is screwed together as shown in FIG. 2, so that the depressed state of the head 23 is maintained. At this time, the suction valve 7 is forcibly closed by the presser rod 21, so that even if the container falls over, no liquid will leak.

The illustrated example shows a container that directly discharges an appropriate amount of liquid among liquid ejectors, but by providing a known spraying mechanism or foaming mechanism in the head, it can be used as a spraying container or a foaming container as it is. .

``Effects of the idea'' This idea has the structure described above, so the number of parts can be reduced.
Therefore, it is easy to manufacture and can be assembled quickly, and since the cylinder stands upward from the first top wall of the cap-shaped member 3, when the cylinder is vertically installed inside the container body as in the conventional case, it can be easily assembled. Compared to this, the liquid capacity can be increased. Furthermore, since a stem is not required, the entire structure can be made compact.
