Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouring cock used by being attached to a pouring outlet of a liquid container, and more particularly to a pouring cock capable of adjusting a flow rate.

[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]

Although such a conventional discharging tool is provided with an idling prevention projection for preventing idling of the inner cylinder in a state where the discharging is stopped, the bottom of the inner cylinder is the outer cylinder. In the discharge stop state, even if the outer cylinder and the inner cylinder are in contact with each other, they are only in surface contact with each other and their liquid-tightness There is a drawback that the property is insufficient and the risk of dripping or leakage is high.

Further, Japanese Utility Model Laid-Open No. 5-77048 discloses a pouring cock whose liquid tightness is improved to prevent liquid leakage. However, this pouring cock has a drawback in that it cannot control the flow rate because the entire discharge port is opened all at once, and is not suitable for pouring a relatively small amount.

The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to provide a pouring cock capable of adjusting the pouring flow rate.

[0006]

In order to achieve the above object, a pouring cock according to the present invention has a cylindrical cock body having an inflow port at a side portion and a discharge port at a lower portion, and the cock body. And a handle rotatably fitted in the upper end opening of the cylinder body and slidably provided on the inner wall of the cylinder body of the cock body to move up and down in the cylinder body by the rotation of the handle to move the contents flow path of the cock body. A plunger that opens and closes, the tip of the plunger is formed in a taper shape, and the tip of the plunger and the discharge port of the cock body engage with each other at the closed position of the content passage of the cock body. It is characterized in that the discharge port is closed.

Further, the pouring cock of the present invention is characterized in that the tip of the plunger is formed in a tapered shape so as to narrow downward.

Further, the pouring cock of the present invention is characterized in that the tip of the plunger is formed in a taper shape so as to spread downward.

Further, the pouring cock of the present invention is characterized in that the tip of the plunger is formed by cutting a cylindrical shape obliquely downward.

Further, the pouring cock of the present invention is characterized in that a hard material is interposed in an engaging portion between the tip end portion of the plunger and the discharge port of the cock body.

[0011]

In the present invention as described above, since the tip of the plunger is formed in a tapered shape, when the handle is rotated to move the plunger upward or downward to open the discharge port. As the plunger moves up and down, the opening area of the discharge port gradually increases, so that the pouring flow rate can be easily adjusted.

Further, when the tip of the plunger is formed in a taper shape that spreads downward, the handle is rotated to lower the tip of the plunger below the discharge port of the cock body, so that the discharge port is opened. It is opened, but when the cock is closed, the tip of the plunger is not stored and left exposed in the cock body, which is particularly hygienic.

Further, a solid material is contained in the content by interposing a member made of a hard resin or the like by fitting the engaging portion between the tip end portion of the plunger and the discharge port of the cock body by fitting. Even when the cock is closed, however, the solid matter existing in the discharge port is eaten up and does not hinder the closure of the discharge port, so the cock can be completely closed.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is an embodiment of the present invention, an external perspective view thereof, FIG. 2 is a sectional view of the same embodiment in which the flow path is open, and FIG. 3 is a view of the same embodiment in which the flow path is open. And FIG. 4 is an explanatory view of the configuration when a stopper member is provided.

Reference numeral 1 denotes a cock body, which is formed in a cylindrical shape and has an inflow port 2 in a lower side portion and a discharge port 3 in 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
Protrusions 6 and 7 for locking the stopper member are provided at two opposing locations on the upper portion of the outer wall surface.

Reference numeral 8 is a handle, and a central cylindrical portion 9 is rotatably fitted in the upper end opening of the cock body 1. The tip (lower end) of the cylindrical portion 9 is slightly opened outward, and its tip 9a is in contact with the inner wall surface of the cock body 1. This ensures a tight seal,
At the same time as preventing the liquid from leaking upward, the contact area with the inner wall of the cock body 1 can be reduced and the handle 8 can be rotated smoothly. A spiral groove 10 is provided on the inner wall surface of the cylindrical portion 9.

Reference numeral 11 denotes a plunger, and projections 12 which engage with the spiral groove 10 provided on the inner wall surface of the cylindrical portion 9 are provided at two locations on the upper portion of the outer wall surface thereof. 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. Further, the tip of the plunger 11 is formed in a shape having a cutting surface 15 obtained by obliquely cutting one side of a cylinder downward, and when the plunger 11 descends to the bottom, the tip portion thereof has a cock body. The discharge port 3 of No. 1 is engaged with and closed.

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

Next, the method of use will be explained. First, when the handle 8 is rotated counterclockwise, the plunger 11 rises, and when it is raised to the top, the rotation of the handle 8 is stopped and the contents The flow path of the object is completely opened (state shown in FIG. 2). As described above, the tip of the plunger 11 is a cut surface 1 obtained by obliquely cutting one side of the cylinder downward.
Plunger 1 because it is formed in the shape having 5
Since the opening area of the discharge port 3 gradually increases with the increase of 1, the flow rate of the discharged liquid can be easily adjusted by rotating the handle 8 and bringing the plunger 11 to an appropriate height position. Yes (eg, as shown in FIG. 3).

When the handle 8 is rotated counterclockwise, the plunger 11 descends, and when the tip of the plunger 11 engages with the discharge port 3 of the cock body 1, the discharge port 3 is completely removed. And the liquid discharge is stopped (Fig. 1
State).

If the stopper member 16 as shown in FIG. 4 is fitted in the upper portion of the spout cock with the discharge port 3 closed, the rotation of the handle 8 is prevented, so that the spout cock is opened. There is no inconvenience that the handle 8 is erroneously rotated and the liquid is discharged when it is transported and stored while being attached to the liquid storage container 5. Further, instead of using such a stopper member, the cock body 1 and the handle 8 are provided with means capable of engaging with each other, and the cock body and the handle are engaged with each other at the closed position of the content passage of the cock body. It is also possible to do so.

FIG. 5 is an external perspective view showing another embodiment of the present invention, and FIG. 6 is a cross-sectional view of the same embodiment with the flow path opened.

The pouring cock in this embodiment has substantially the same overall structure as the pouring cock in the above-mentioned embodiments, but as shown in FIGS. 5 and 6, the tip of the cylindrical plunger 11 is Taper shape that narrows downward,
That is, it is formed in a conical shape that is convex downward. In such a structure, when the handle 8 is rotated counterclockwise, the plunger 11 rises and the plunger 1
Since the opening area of the discharge port 3 gradually increases with the increase of 1, the flow rate of the discharged liquid can be easily adjusted by rotating the handle 8 and bringing the plunger 11 to an appropriate height position. Yes (for example, the state shown in FIG. 6).

FIG. 7 shows another embodiment of the present invention. FIG. 7 is a cross-sectional view showing a closed flow path, FIG. 8 is an enlarged view of a portion A of FIG. 7, and FIG. 9 is a plunger of the same embodiment. FIG. 10 is an external perspective view showing the structure, and FIG. 10 is an external perspective view showing the structure of the claw portion provided on the plunger of FIG.

In this embodiment, the plunger 17 has a structure as shown in FIG. That is, the spiral groove engaging portion 17a, the pillar portion 17b, and the plunger portion 17c.
Is integrally provided, and the spiral groove engaging portion 17a is provided with a protrusion 20 that engages with the spiral groove 10 provided on the inner wall surface of the cylindrical portion 9 of the handle 8. Further, two claws 18 are provided on the right and left sides of the column portion 17b, and these claws 18 are engaged with two guide protrusions 19 on the left and right which are vertically provided from the central portion to the lower portion of the inner wall surface of the cock body 1. Then, the plunger 17 moves up and down while being guided by it. Further, the plunger portion 17c is formed in a taper shape so as to spread downward. In this embodiment, when the plunger 17 rises to the top, the plunger portion 17c at the tip of the plunger 17 engages with the discharge port 3 of the cock body 1 to close it (FIG. 7). State). Other structures are the same as those in the above-mentioned embodiment. A member 21 made of a suitable hard material is fitted around the discharge port 3 of the cock body 1 to interpose the hard material in the engaging portion between the plunger portion 17c and the discharge port 3 (FIG. 8). reference). As such a hard material, a hard resin such as polystyrene (particularly preferably polystyrene having excellent transparency) or ABS resin is used.

In such a structure, when the handle 8 is rotated, the plunger 17 descends and the opening area of the discharge port 3 gradually expands as the plunger 17 descends. Flow rate is handle 8
If the plunger 17 is brought to a proper height position by rotating, it can be easily adjusted. The cylindrical portion 9
When the inner spiral groove 10 is provided in the same direction as that of the above-described embodiment, in the structure of this embodiment, when the handle 8 is turned counterclockwise, the cock is closed, so that the sense of discomfort in the rotating direction of the handle 8 is eliminated. To this end, it is desirable to provide the spiral groove 10 in the direction opposite to that of the above-described embodiment. In this embodiment, the handle 8 is thus rotated to lower the tip of the plunger 17 below the discharge port 3 of the cock body 1 to open the discharge port 3, but the cock is closed. In the closed state, that is, when the plunger 17 is raised to the top, the tip of the plunger 17 is stored in the cock body 1, and the tip of the plunger 17 remains exposed when not in use. Since it does not occur, especially when the content is food, it is preferable because it is hygienic.

Further, as described above, by interposing the member 21 made of hard resin or the like with the engaging portion between the tip end portion of the plunger 17 and the discharge port 3 by fitting or the like, for example, tomato sauce or the like. Even when such liquid contents include solid matter such as scraps of vegetables and pulp, the solid matter present in the discharge port 3 is cut off when the cock is closed and the discharge port 3 is closed. It is possible to close the cock completely as it does not become an obstacle. Also in the above-mentioned embodiment, it is of course preferable to interpose such a hard material in the discharge port 3 of the cock.

Incidentally, it can be said that it is common to all of the embodiment shown in FIG. 1, the embodiment shown in FIG. 5, and the embodiment shown in FIG. Since the open space of the flow path becomes wider in the initial stage of pouring when the angle is formed more gently than when it is formed steeply, it is possible to suppress the vigorous discharge,
A stable pouring adjustment is possible at all times.

[0030]

As described in detail above, according to the pouring cock of the present invention, since the tip of the plunger is formed in a tapered shape, the plunger is moved up or down by rotating the handle. When opening the discharge port, the opening area of the discharge port gradually expands as the plunger moves up and down, so if you need to dispense a large amount of content at one time and divide it into small containers, The use of the pouring cock of the invention has an excellent effect that the pouring flow rate can be easily adjusted.

Further, when the tip of the plunger of the pouring cock of the present invention is formed in a taper shape which spreads downward, the handle is rotated so that the tip of the plunger is located above the discharge port of the cock body. The tip of the plunger is stored in the body of the cock when the cock is closed, and the tip of the plunger remains exposed when not in use, because the discharge port opens when the cock is closed. It is especially hygienic because it does not exist.

Further, a solid material is contained in the contents, for example, by inserting a hard material into the engaging portion between the tip of the plunger of the pouring cock of the present invention and the discharge port of the cock so as to intervene. In such a case as well, when the cock is closed, the solid matter existing in the discharge port is eaten up and does not hinder the closing of the discharge port, so that the cock can be completely closed.
