[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spout cock attached to a spout of a liquid storage container, and more particularly to a spout cock which is free from dripping and has excellent operability.

[0002]

2. Description of the Related Art Conventionally, as a pouring device of this type, for example, as described in Japanese Utility Model Laid-Open Publication No. Sho 62-182255, an outer cylinder having an inlet and an outlet hole and an upper end of the outer cylinder are disclosed. A knob portion to be stopped, and an inner cylinder spirally engaged with a joining portion provided at the center of the knob portion, and rotation of the knob portion causes the inner cylinder to move up and down in the outer cylinder to stop discharging and stopping the liquid. Ejectors that do this are known.

[0003]

Such a conventional discharging tool is provided with an anti-slip projection for preventing the inner cylinder from idling when the discharge is stopped, but the bottom of the inner cylinder has an outer cylinder. In the discharge stop state, even if the outer cylinder and the inner cylinder coincide with each other at the outflow hole of the outer cylinder, they are merely in surface contact with each other, and the The properties are insufficient, and there is a drawback that the risk of dripping or leakage is high.

The present invention has been made in view of the above-mentioned drawbacks, and has as its object to provide a liquid ejecting apparatus which is excellent in liquid tightness in a state where discharge is stopped, does not cause dripping at all, and has excellent operability. Serving cooks.

[0005]

In order to achieve the above object, a spout cock according to the present invention has a cylindrical cock body having an inflow port on the side and a discharge port at a lower portion, and the cock body. A handle rotatably fitted into the upper end opening of the cylindrical portion, and a slidably provided inner wall of the cylindrical portion of the cock main body. The cock body and the handle are provided with a plunger that can be opened and closed, and the cock body and the handle are provided with means capable of engaging with each other. It is characterized by having done.

[0006]

In the present invention, the plunger is lowered by the rotation of the handle to enter the discharge port of the cock body, and the bulge at the tip of the plunger rides over the inner wall of the discharge port and the two are engaged. When the user touches the handle, the handle feels a clicking sound, and at the same time, since the handle and the cock main body are engaged with each other, it can be visually confirmed that the discharge port is closed, so that the operability is extremely improved.

In the state where the discharge port is closed, the handle and the cock main body are engaged with each other, so that careless rotation of the handle is prevented, so that the handle is erroneously rotated during transportation and storage, and the liquid is discharged. Such inconvenience does not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a sectional view of an embodiment of the present invention in which a flow path is opened, FIG. 2 is an enlarged view of a portion A in FIG. 1, and FIG. 3 is an embodiment of the present invention. Sectional view in closed state, FIG.
5 and FIG. 5 are a plan view and an external perspective view, respectively, of a state in which the flow path is closed as in FIG.

Reference numeral 1 denotes a cock body which is formed in a cylindrical shape, has an inflow port 2 at a lower side, and has a discharge port 3 at a lower portion. The spout cock of the present invention is attached to the spout of the liquid storage container 5 through the joint 4 provided at the inflow port 2 of the cock body 1, and both are connected. In addition, cock body 1
An engagement stopper 6 is provided at the upper end of the outer wall surface.

Reference numeral 8 denotes a handle, and a central cylindrical portion 9 is rotatably fitted in an upper end opening of the cock body 1. The distal end (lower end) of the cylindrical portion 9 is slightly opened outwardly, and the distal end 9 a is in contact with the inner wall surface of the cock body 1. This ensures a tight seal,
While preventing upward liquid leakage, the contact area with the inner wall of the cock main body 1 can be reduced, and the rotation of the handle 8 is also smooth. A spiral groove 10 is provided on the inner wall surface of the cylindrical portion 9. Further, a projection 7 is provided at the lower end of the outer wall surface of the handle 8 so as to be able to engage with the engagement stopper 6 of the cock body 1.

Reference numeral 11 denotes a plunger, and projections 12 for engaging with the spiral grooves 10 provided on the inner wall surface of the cylindrical portion 9 are provided at two positions on the outer wall surface of the plunger. Therefore, when the handle 8 is rotated, the cylindrical portion 9 is also rotated, and at the same time, the entire plunger 11 moves up and down in the cock body 1. At this time, the claw 13 provided below the outer wall surface of the plunger 11 engages with the guide protrusion 14 provided vertically from the center to the lower portion of the inner wall surface of the cock body 1 and is guided by this, so that the plan The jar 11 moves up and down without its tip portion swinging. When the plunger 11 descends to the bottom, its tip (lower end) engages with the discharge port 3 of the cock body 1 to close it. As is apparent from FIG. 2, in the present invention, the tip of the plunger 11 forms a bulged portion 15 whose periphery is slightly bulged.

The spout cock of the present invention is made of synthetic resin.

Next, the method of use will be described. First, when the handle 8 is rotated counterclockwise, the plunger 11 rises, and when it reaches the top, the rotation of the handle 8 is stopped and The flow path of the object is completely opened (state shown in FIG. 1). The flow rate of the discharged liquid can be easily adjusted by rotating the handle 8 to bring the plunger 11 to an appropriate height position.

When the handle 8 is rotated clockwise in the opposite direction, the plunger 11 descends, and when the tip of the plunger 11 enters the discharge port 3 of the cock body 1, the bulging portion 15 at the tip of the plunger 11. Are in contact with each other while over the inner wall of the discharge port 3, the two are engaged, the discharge port 3 is completely closed, and the discharge of liquid is stopped (the state shown in FIG. 3). Since the liquid-tightness at the discharge port in this state is good, problems such as liquid dripping do not occur. When the bulging portion 15 at the tip of the plunger 11 climbs over the inner wall of the discharge port 3 and the two engage with each other, a clicking sound is obtained. Since the engagement stopper 6 engages with the upper position at a relatively easy-to-see position, it can be seen from this that the discharge port 3 is closed, so that the operability is very good.

When the discharge port 3 is closed as described above, the handle 8 and the cock main body 1 are engaged with each other to prevent the handle 8 from being inadvertently rotated. There is no inconvenience that the handle 8 is erroneously rotated and the liquid is discharged when transported and stored in a state in which the liquid is attached.

The shapes of the projection 7 and the engagement stopper 6 for engaging the handle 8 with the cock body 1 are not limited to the present embodiment. For example, the projection 7 'and the engagement It may be shaped like a stopper 6 '.

[0018]

As described in detail above, according to the pouring cock of the present invention, when the plunger tip enters the discharge port of the cock body, the bulging portion of the plunger tip forms the discharge port inner wall. When they come in contact with each other, they come into contact with each other to close the discharge port, and at this time, the handle and the cock main body are engaged at an easy-to-see upper position. The operability is very good because the exit is closed.

Further, when the discharge port is closed, the handle and the cock body are engaged with each other to prevent the handle from being rotated carelessly. Can be eliminated.
