By accommodating the bifurcated spring 41 and elastically engaging the engaging claws 41b formed on the outer surfaces of both arms 41a of the spring 41 with the engaging unevenness 37e, the passage cover 36 and the tip tube 35 can be moved to any position. It is designed to be moved and locked to stabilize the spout 30 at a desired height that matches the liquid receiving container 42. The upper end portion 37f of the downward guide path cover 37 is fitted into and held by a cylindrical portion 5c formed on the lower surface of the beak-shaped portion 5a of the shoulder portion 5. The downward guide path cover 37 completely hides the boundary between the path cover 36 and the base tube 34, which are displaced up and down when the height of the spout 30 is adjusted, resulting in an elegant configuration in appearance. I can do it. Further, since the downward guide path cover 37 functions as a guide member for guiding the vertical movement of the passage cover 36 and as an upward movement positioning member for the spout portion 31 of the downward guide path B, a separate upward movement positioning mechanism is required. It is not necessary to use this method, and the configuration can be simplified. Note that the spring 41 may be formed of a metal wire. In the embodiment shown in FIGS. 7 to 10, a downward guide path cover 37 having a cover portion 37b is provided over the entire length from the same height as the shoulder 5a on the outer surface of the container body 1 to the lower part of the container body 1. , attach the base plate 37b, which has been screwed 51 to the back surface of the cover part 37b, to the exterior case 2 by screwing 52, and connect the spout 31 of the tip tube 35 and the spout 31 of the movable passage cover 36 to the tip tube 35.

By elastically engaging the unevenness 37g, the spout 30 can be locked at an arbitrary height. The passage cover 36 and the tip tube 35 are fixed with screws 55 so that they can move up and down integrally.

Although the base tube portion 34 is integrally formed with the beak-shaped portion 5a of the shoulder portion 5 and is hung therefrom, it may be held detachably as in the previous embodiment. The spout part 31 is bent almost horizontally, and after pouring, residual drops that remain scattered in the long downward guide path B gradually join together while falling down, and when a small amount has been sent to a considerable extent, the spout opens. 3
The water that is about to flow down from zero is retained by surface tension on the bottom surface of the spout portion 31, which is horizontal compared to the amount of water, and is prevented from flowing out. The downward guide path B is a rectangular passage with a flat cross section, and the degree of protrusion of the extending portion from the outer surface of the vessel body 1 is reduced. Therefore, the discharge port 33 of the spout pipe 17 is also opened in a similar rectangular shape. Figures 11 to 13 are

Furthermore, an O-ring 106 is fitted to the lower part of the upper end flange 34a of the base tube 34, which is received in the opening 32 formed at the bottom of the beak-shaped part 5a of the shoulder 5, to prevent liquid from leaking from the opening 32. It is prevented. The other configurations are not much different from those in FIG. 1, and their explanation will be omitted.

Effects According to this invention, the downward guide path is provided along the outer surface of the front part of the vessel, and has a simple structure! In addition, since a bent part is formed within the downward guide path cover that covers it and separates the lower end spout by a predetermined amount from the outer surface of the container, the complex configuration that has a bent part in addition to the vertical moving part is hidden. ,
It does not damage the appearance of the container, is well protected from external forces, and prevents the operator from touching it directly when dispensing the contents.

The downward guide path is provided along the outer surface of the front part of the container body, and only the part below the lower bent part protrudes, so the protrusion of the downward guide path with the cover to the outer surface of the container body is adjusted as described above. In addition to being able to adjust the height of the lower end spout along the outer surface of the container, the small protruding state is always maintained, preventing the container from becoming bulky and unsightly and difficult to handle. This will prevent it from becoming difficult. Further, the position of the spout from the outside of the container does not change due to height adjustment, and liquid can be poured safely. Furthermore, by making the part that covers from the bent part of the cover to the spout the most protruding part, there is an advantage that it can be a safe and easy-to-operate operation section for adjusting the spout height.
