[Means for solving the problem]

According to the present invention, a top plate 2 is integrally formed on the top of a tubular container body 1, a suction hole 3 is provided in the top plate 2, and a fitting cylinder 5 is erected around the suction hole 3 so as to stand upright. Valve body in cylinder 5
A tubular portion 20 of 19 is fitted, a suction side check valve 21 capable of opening and closing the suction hole 3 is integrally connected to the lower portion of the tubular portion 20, and an upper portion of the tubular portion 20 is provided. An annular discharge-side check valve 24, which expands outward and extends obliquely upward, is integrally connected, and is formed on the top of the container body 1 with an elastic material. The pump member 15 is fitted, and the pump member 15 is provided with a bulging portion 18 that bulges upward. The lower peripheral edge portion 16 of the bulging portion 18 is formed into the annular discharge side check valve.
The pump member 15 is provided in contact with 24,
A discharge cylinder 22 is provided, and further, on the top of the container body 1,
A cover 30 is fitted and the cover 30 is fitted with the pump member.
The dispensing cylinder 32 fitted to the 15 dispensing cylinders 22 is provided.
A push button 36 is integrally connected to the 32 through a resilient hinge 35, and the push button 36 is formed so as to press the bulging portion 18. An annular wall 34 that covers the periphery of the bulging portion 18 of the member 15 is provided, and the annular wall 34 is formed so as to also surround the front portion of the push button 36 that has been pressed down, to obtain a container with a dispensing device.

[Action]

According to the present invention, when the cap 41 and the plug 40 are removed and the push button 36 is pushed down from the state shown in FIG. 1, the contents filled in the bulging portion 18 of the pump member 15 are discharged to the discharge cylinder 22 by a predetermined amount. Is extruded and poured out from the pouring tube 32.

When the pressing of the push button 36 is stopped, the bulging part of the pump member 15
The valve 18 is restored to its original bulging state, and the contents in the container body 1 are sucked into the bulging portion 18 by pushing the suction side check valve 21 open.

Since the valve seat with which the discharge side check valve 24 abuts uses the lower peripheral edge portion 16 of the bulging portion 18 of the pump member 15, the structure of the discharge side check valve portion can be simplified. You can

The bulging portion 18 is pressed by a push button 36 connected to the pouring tube 32 via a hinge 35. Further, an annular wall 34 covering the bulging portion 18 of the pump member 15 is formed. Is provided so that the annular wall 34 also surrounds the front portion of the pushed pushbutton 36.

Therefore, when pouring the contents by pushing the tip of the push button 36 on the side opposite to the spout 33, which is the position where the push button 36 is easy to push, with a finger, the position of the finger pushing the push button 36 is slightly Different, and even if the pushing force of the finger pushing the push button 36 is slightly different, the finger pushing the push button 36 abuts on the annular wall 34 surrounding the front part of the push button 36 and stops at a certain height. To do.

Therefore, the pump member 15 has a bulge 18
You can press to press to dispense a fixed amount.
