Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water faucet for a container, which can prevent water leakage from the container and can drain water from the container if necessary.

[0002]

2. Description of the Related Art Conventionally, some water tanks and other containers are provided with a capped opening. However, such a container not only prevents leakage of water but also facilitates water supply and drainage by opening the cap. It is very convenient because it can be done. On the other hand, with a container that does not have such an opening, the container is often tilted or inverted during drainage, which often causes inconvenience.

For example, in milk and other beverages for home delivery, these beverages are housed in a cold storage container together with a cooling agent such as rock ice in the summer and are delivered to the home. Sometimes the container gets submerged,
Moreover, since there is no drainage port, it was troublesome that the container had to be inverted during drainage.

Therefore, there is a plan to provide a drainage port in the cold insulation container and provide a water faucet at the drainage port to prevent water leakage when the cold insulation agent is dissolved and to allow smooth drainage as necessary. Was proposed. For example, as the faucet,
What is pressed into the drain port from the inside of the container like a rubber stopper,
Alternatively, a lid-shaped member made of resin and capable of opening and closing via a hinge has been raised.

[0005]

However, according to the one in which the stopper is provided from the inside of the container, there is a fear that the container cannot be opened when there is an item contained in the container, and moreover, the opening and closing of the stopper is troublesome and the stored water is not opened. There are drawbacks such as getting your hands wet.

[0006] Further, a resin faucet having a lid-like faucet has a poor sealing property as the opening / closing operation is repeated. If there is a crack in the end, there is a problem in durability such as breakage due to the notch effect. Furthermore,
This type of faucet has a drawback in that it is inadvertently opened due to water pressure or impact, and the operability is poor because the opening / closing direction is restricted to one direction.

In addition, conventionally, there is also a water tap having a structure such as a tap, but in that case, the amount of protrusion becomes large when it is attached to a container, which is dangerous, and the operability is also important. There were many problems such as poor taste.

Therefore, the present invention is intended to provide a new faucet which is durable and has good operability, and can be smoothly drained from the container when necessary.

[0009]

In order to achieve the above-mentioned object, the present invention comprises a tubular member having a valve seat portion and a seat portion each having an opening on the inner peripheral surface thereof, and a valve body incorporated in the tubular member. The tubular member is formed in a corrugated cam surface at one end and is attached to the opening of the container with the cam surface serving as an outlet side, and the valve body is housed between the valve seat portion and the seating portion. And a valve rod penetrating the seat, and is urged toward the valve seat by a spring provided around the valve rod, and one end of the valve rod slidably contacts the cam surface. There is provided a water faucet for a container, wherein a handle is mounted and the opening of the valve seat portion is opened and closed by rotating the handle.

[0010]

According to the present invention, the valve body seals the opening of the valve seat during normal times to prevent water leakage from the container. When the handle is turned a certain amount in that state, the valve body moves backward against the spring force, and at this time, the opening of the valve seat portion is opened.

Then, water or other fluid in the container comes to flow out through the openings of the valve seat portion and the seat portion.
Then, when the handle is returned to the initial state thereafter, the valve body is pushed back by the spring, and the opening of the valve seat portion is sealed.
