Description

[Detailed Description of the Invention] This invention relates to a spout device for a liquid container such as a pot, which has a built-in manual or electric liquid dispensing pump.

Liquid containers equipped with this type of pump are generally large in size and have a large capacity, and are also tall.

The dispensing pipe that brings out the liquid dispensed by the pump outside the vessel is configured to open above the front of the vessel, so it is difficult to place the liquid on a table or the like on which the vessel is placed. If you place a liquid receiving container such as a pot on the same plane and perform the above-mentioned dispensing, there is a large head difference between the spout and the liquid receiving container, so the droplets scattered on the liquid surface of the liquid receiving container may be scattered around the surrounding area. There is an inconvenience that it scatters and wets the tabletop.

-On the other hand, if you hold the liquid receiving container in your hand and hold it near the spout to perform the pouring process, you can prevent the droplets from scattering to the surrounding area as described above, but
If the liquid content is boiling water, there is an inconvenience that high heat will be transmitted to the hand holding the liquid receiving container.

In addition, this type of liquid container is most often used as a heat insulating container for hot water, so the inconvenience that the hand holding the liquid receiving container cannot withstand the heat cannot be avoided with this type of container.
This is the biggest drawback.

This invention solves the above-mentioned problems in that it can be selectively and easily handled and used in the conventional manner. In a liquid container, the spout of the spout is opened by looking downward at a part of the upper front of the container, at least at the front and rear of the container. A spouting auxiliary pipe is provided that is provided with a pipe joint part that can be swung in the direction and is configured to be extendable and retractable in the length direction, and the auxiliary pipe is removably attached to the spout of the spouting pipe from below. .

Due to the above configuration, the auxiliary spout pipe is attached to and removed from the spout of the spout pipe from below, and its use or non-use is selected.6 When in use, the spouted content liquid from the spout of the spout pipe is transferred to the container. Guide downward.

This guidance is achieved by expanding and contracting the auxiliary dispensing pipe to the desired height, and by swinging the auxiliary dispensing pipe around the pipe joint, the dispensing liquid is directed to a desired distance from the container body. It can be leaked.

Furthermore, a concave groove 58 that bulges out in the radial direction is provided on the inner surface of the lower end opening of the expandable tube body 39F, so that when pouring out the liquid contained in the liquid container,
This prevents the last drop that descends through the auxiliary spouting pipe 35 from dripping from the opening of the telescopic tube body 39F. When removed from below 35, it is possible to prevent drops from accidentally dripping onto a table or the like.

It goes without saying that the above embodiments can be implemented in combination with each other.

According to this invention, the auxiliary spout pipe can be easily attached to and removed from the bottom of the spout of the spout pipe in a regular pump-type liquid container, allowing users to select whether to use it or not. It is very convenient, and when in use, the liquid dispensed from the spout is guided further down the container body so that it can be easily and safely poured into the liquid receiving container that is left in place. The liquid injection height can be changed to match the height of the liquid receiving container, and by swinging around the pipe joint, the distance between the liquid receiving port of the liquid receiving container and the container body can be adjusted to match the distance from the container body. It is possible to inject liquid at any position.

In particular, adjustment of the distance from the container body for injecting liquid can be easily achieved by at least the pipe joint function that allows back and forth rocking without getting in the way of the surroundings, providing excellent usability.
