[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container discharging device for discharging contents by a pump device or the like.

[0002]

2. Description of the Related Art Conventionally, in a dispenser for a container for discharging contents by a pump device or the like, a valve is opened by a pressure for discharging the contents, and a pressure of the contents is reduced by stopping the operation of discharging the contents. Container dispensers configured to close the valve are well known.

[0003] Then, note Daegu of said container, since the formed so as to open the pouring outlet by moving the valve by the pressure of the contents, there are dispensing passage having a power spring, etc. around the valve, this The pouring path is complicated by the valves and splicers.
ing. Therefore, the number of parts and man-
Was causing an increase in strikes.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and has a simple structure for dispensing a container for opening and closing a pouring passage by pressure of the contents. It is another technical object of the present invention to prevent the liquid remaining in the pouring path from dropping from the pouring port.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a pouring head 1.
And a cylindrical body 1 communicating with a content discharging path 2 of the discharging head 1.
0 is provided on the inner peripheral tip side of the cylindrical body 10.
2, the valve stem 28 is inserted into the tubular body 10, the base mounting portion 29 of the valve stem 28 is attached to the pouring head 1, and an elastic force is applied between the tubular body 10 and the valve stem 28. With resin
Fitted slidably the pouring cylinder 20 integrally molded front and rear, the base end portion 22 of the pouring cylinder 20 and a larger diameter, the tubular member
10 is held in a liquid-tight manner against the inner surface of
Further , an elastic protruding piece 21 which is locked to the locking step 12 is provided integrally with the outside of the pouring cylinder 20, and the pouring cylinder 20 moves forward by the pressure in the pouring cylinder 20, and the locking At the position where the elastic protruding piece 21 abutting on the step portion 12 is greatly bent and advanced, the spout 23 of the pouring cylinder 20 abutting on the distal end of the valve rod 28
Is opened, the the spout 23 of the elastic key 21 the pouring cylinder 20 by deflection to restore is small or non-contents thereof is retracted in the opposite direction, the tip portion of the valve stem 28 As a result, the spout 23 was closed, and the contents around the spout 23 were pushed back into the spout cylinder 20 to form a container spout.

[0006]

SUMMARY OF Invention The present invention, the pump device, or by applying press body of the flexible container, the contents of the container are pressed pouring the contents pouring outlet 2 of the head 1. The contents flow into the pouring tube 20 from the contents pouring path 2 and press the pouring tube 20 forward.

[0007] Then, the ejection tube 20 is provided with the elastic protruding piece 21.
The base end portion 22 slides against the inner surface of the tubular body 10 to advance while bending, and the spout 23 of the spouting tube 20 is opened apart from the tip end of the valve rod 28, and the contents are spouted 23. It is poured out from outside.

When the pressing of the body of the pump device or the container is stopped, the elastic projection piece 21 which has been largely bent is restored, the pouring tube 20 is retracted, and the pouring port 23 of the pouring tube 20 is retracted.
However, the spout 23 is closed by contacting the tip of the valve rod 28. In this state, the bending of the elastic projection piece 21 is small.
It is nothing. If this deflection is small, the spout 23
Press out to the tip of valve stem 28 and pour if there is no deflection
The port 23 contacts the tip of the valve stem 28. Base of dispensing cylinder 20
The end 22 is formed to have a large diameter to increase liquid tightness and to reduce viscosity.
Liquid leakage can be reliably prevented. At this time, the cylindrical body 10
The dispensing cylinder 20 that is in close contact with the
It can be returned to the original position. Thus, in the present invention
According to this, there is an advantage that liquid leakage can be almost completely eliminated.

[0009]
