Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a spout device used in a liquid container such as a thermos flask, in which the content is poured out using a manual or electric pump.

Conventional technology and the problems it attempts to solve This type of pump-dispensing liquid container does not require work such as lifting and tilting the container, so it is generally large with a large capacity and has a long back. expensive.
For this reason, if the spout channel that guides the liquid dispensed by the pump to the outside simply opens its spout downward to one side of the shoulder of the liquid container body, the opening position will be too high and it will not be able to receive the liquid content. There is the hassle of having to lift a cup or other liquid receiving container close to the spout to receive the liquid contents, and the risk of hot water splashing on the liquid receiving container and the hand holding it, resulting in hot sensations or burns. There is a risk of dropping the liquid container. In order to solve this problem, it is already known that the spout channel is extended downward and lowered.
If you simply do that with the conventional type, you will not be able to adapt it to liquid receiving containers of various heights. The spout must be kept far away from the container body in order to fit both the
It's bulky around the torso.

Means of problem solving Therefore, in this invention, in order to achieve the above purpose,
It is equipped with a content liquid dispensing pump and a dispensing path that guides the content dispensed by the pump to the outside, and further guides the content liquid downward from an overhanging part of the dispensing path to one side of the shoulder of the liquid container. A long downward guide path is provided, and the downward guide path is centered on an upper base located close to the liquid container, and has a non-pour position along the outer surface of the liquid container and a pour position extending from the outer surface of the liquid container. The liquid container is provided with a position regulating means for regulating at least the non-pour position of the downward guide path.

Function: The downward guide path receives the dispensing content liquid at the desired projecting position due to its rocking and guides it downward.
Inject the liquid at the desired distance from the container. In the non-pour position, the position is regulated along the outer surface of the vessel by a position regulating means, and the position regulating means functions to indicate the origin of the return of the downward guide path to the non-pour position.

Embodiment The embodiment shown in FIGS. 1 to 3 will be described. Reference numeral 1 denotes a liquid container body, which is a so-called thermos flask with a double vacuum bottle 3 housed inside an outer case 2. A dish-shaped shoulder part 5 having a hot water supply port 4 communicating with the bottle 3 is integrally attached to the upper end of the outer case 2, and a lid 7 equipped with a manual bellows pump 6 is provided on the shoulder part 5. The lid 7 is pivoted 8 to the rear of the shoulder 5 and can be opened and closed. Hot water supply port 4

When dispensing, once the content liquid comes out, the downward guide path 11e
A siphon phenomenon occurs due to the long time, and the content liquid 1
0 is automatically dispensed until the inside of the bottle 3 becomes negative pressure. Therefore, there is no inconvenience of having to operate the pump 6 frequently in order to bring the inside of the bottle 3 to a predetermined pressure in order to pour out the liquid content, unlike in the past, and it is also easier to operate.
If the structure is such that outside air is supplied into the bottle 3 during automatic dispensing, automatic dispensing can be continued. This automatic dispensing can be stopped at any time by releasing the press plate 35, which restores the valve 34 together with the pump 6 and closes the dispensing passage 11.

In FIG. 4, the downward guide path 11e is made expandable and retractable by a base tube 51 and a tip tube 52 that are slidably fitted together through a packing 53, and the height of the spout 11h is expanded and contracted. can also be adapted to the height of the mouth of the liquid receiving container. As shown in the figure, if the downward guide path 11e is stored in the contracted state in the non-pour position, the area around the main body 1 becomes even less bulky.

Effects According to this invention, the dispensing channel is provided with a long downward guide path that guides the liquid content further downward from the overhanging part on one side of the shoulder of the liquid container main body, and the liquid receiving container is kept stationary. On the other hand, the downward guide path allows for safe and easy pouring without the trouble and danger of lifting and receiving liquid.
It can swing around an upper base located close to the liquid container, receives the dispensed content at a desired protruding position from the liquid container and guides it downward, and allows each liquid receiving container to have a different position relative to the liquid container. It is possible to more safely and easily pour liquid from a position corresponding to the natural liquid receiving port position, and since it is placed close to the outer surface of the liquid container when not pouring, there is almost no bulk around the body of the liquid container. To make a liquid container look good, easy to handle, and not get in the way. Furthermore, the structure does not become particularly complicated as long as the downward guide path is able to rotate in an arc around the upper base near the liquid container.

In particular, in this invention, the pivotable downward guide tube is shown at least the origin of pivoting, which is the non-pourout position, by position regulating means such as a cover or a link, and the reckless use of pivoting is prevented. After use, the user is prompted to return to the origin to the non-pour position, and the pipe is left in the swung extended state in the spout position, eliminating the possibility of it getting caught on the other end.
