Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a liquid container such as a thermos flask whose contents are dispensed by a manual or electric pump. This invention relates to a pouring spout device for a liquid container, which is provided with a downward guide path that guides the liquid to be poured from the upper part of the container body to the lower side 5 and allows the height of the lower end spout to be adjusted.

Prior Art Such a liquid container is disclosed in, for example, Utility Model Application Publication No. 53-16295.
This method has already been proposed as known in Japanese Patent No. 5 and Japanese Utility Model Publication No. 1837/1983.

However, the downward guide path and the guide structure attached to it are exposed, and regardless of the spout height adjustment structure, the appearance is complicated and unsightly.
Easily damaged by excessive force during abuse or handling. Also, if you directly touch the downward guide path when pouring hot water, you will feel hot and it is dangerous. Such a risk is particularly likely to occur due to the type of spout height adjustment operation. The present invention provides a liquid container that can eliminate the above-mentioned drawbacks of the conventional art by providing a passage cover on a downward guide path whose lower end spout is adjustable in height so as not to impair its function or operability. The purpose of the present invention is to provide a pouring spout device.

Structure In the present invention, in a liquid container equipped with a content liquid dispensing pump and a dispensing passage for guiding the content dispensed by the pump to the outside, the dispensing content liquid is passed through the dispensing passage to the front of the vessel body. A downward guide path that is positioned to guide downward from the top and has a vertical moving part that adjusts the height of the lower end spout, a fixed passage cover provided at the front of the body to cover the downward guide path, and It is equipped with a movable passage cover that covers the lower moving part of the guideway so as to move with it, and the fixed passage cover and the movable passage cover move from the highest moving position to the lowest moving position as the spout height of the movable passage cover is adjusted. They are arranged so that they can be relatively moved up and down over the entire vertical stroke range.

The fixed passage cover and movable passage cover are at the lower end! The downward guide path including the vertical movement part for adjusting the height of the spout is covered so that it is not exposed to the outside, and is not directly touched by hands or exposed to external force.

In particular, the fixed passage cover and the movable passage cover overlap each other over the entire vertical movement stroke range associated with the adjustment of the spout height of the movable passage cover, so that the downward guide path is not exposed from between them. Embodiment The embodiment shown in FIGS. 1 to 6 will be described. Reference numeral 1 denotes a liquid container body, which forms a thermos flask with a double vacuum bottle 3 housed inside an outer case 2.

The hot water supply port 4 has a stopper that includes an air supply passage 15 that communicates the air discharge port 14 of the air pump 6 with the inside of the bottle 3 when the lid 7 is closed, and a spout passage A that guides the content liquid to the outside. 19 is removably fitted.

The spouting path A includes a liquid discharge pipe 16 that hangs down from the stopper 19 into the bottle 3 and has its lower end opened near the bottom of the bottle, and a liquid outlet pipe 16 that extends from the stopper 19 to the shoulder 5.
It consists of a spouting pipe 17 that extends toward the front of the container body along the top surface, and a passage 21 that communicates the draining pipe 16 and spouting pipe 17 within the stopper 19''. A valve 18 is provided in the passage 21 to allow the pouring pipe 17 to communicate with the valve 18 .
The valve 18 is biased upwardly by a spring 20 to open the outlet pipe 16.
A passage 2 provided in the stopper 19 so as to shut off the spout pipe 17 and the spout pipe 17.
An operating portion 23 is provided which is seated on a valve seat 22 in the valve body 1 and projects through the plug body 19 upwardly.

The air pump 6 has a built-in restoring spring 24 that acts in a direction to expand the internal space of the pump chamber, and by pressing down a pressing plate 25 exposed on the top surface of the lid 7, the air inside the pump chamber is pumped into the supplied air. It is designed to be pumped into the bottle 3 via a passage 15.

The pump 6 is biased downward and supported on the upper wall of the pump 6.

This is a structure in which, by pressing down on the pressing plate 25, the operating rod 28 is moved downward via a spring 29, and the valve 18 is pressed down at the lower end of the operating rod 28, thereby opening the passage 21. Therefore, spring 29 is stronger than spring 20 which urges valve 18 upward. By pushing down the pressure plate 25, the upper wall of the pump 6 is pushed down via the intake valve 26, and the air inside the pump 6 is drawn into the bottle 3.
As described above, the liquid is pumped into the vessel and the liquid is poured out of the vessel through the outlet pipe 16 and the pouring pipe 17.

When the pressing force on the pressing plate 25 is released, the spring 24
, 29 causes the press plate 25, the pump upper wall, and the operating rod 28 to return upward, and at this time the intake valve 26 opens the intake port 27 to allow atmospheric air to flow into the pump chamber. A long downward guide path B for guiding the liquid content further downward is provided in the dispensing path A from an overhanging part to one side of the container shoulder 5, near the outer surface of the container 1,
A spout portion 31 is formed at the lower end of the downward guide path B, which is bent so as to separate the tip spout 30 from the outer surface of the container body 1 .

The downward guide path B is inserted from above into the opening 32 of the beak-shaped portion 5a of the shoulder portion 5 that protrudes from one side of the container body 1, and is held detachably, and the content liquid is discharged from the discharge port 33 of the spout pipe 17. It consists of a base tube 34 that is to receive the spout 30 of the tip tube 35, and a vertically movable tip tube 35 that is fitted onto the outer periphery of the base tube 34 so as to be movable up and down and has the spout 31 at its lower end.
and a movable passage cover 3 that integrally covers all parts except the upper end.
6, and the cover 36 has a U-shaped upper half 3 in cross section.
A partially open hole 36c opened in the top plate 36b of the tip tube 35 is elastically fitted into a groove 35c formed between the upper end flanges 35a and 35b of the tip tube 35, so that the hole 36c can be moved up and down integrally with the tip tube 35. On the other hand, the lower half covers the spout portion 31 and serves as an operation knob 36c for adjusting the height of the spout 30. A fixed passage cover 37 is provided on the outer surface of the container body 1, and the lower end of the base plate 37a is attached to the case 2 with screws 38, and the protrusion 39 in the center is inserted into the hole 40 of the case 2. A cover portion 37b integrally formed in the half portion is intended to cover the downward guide path B. Furthermore, the upper half 36a of the passage cover 36 is slidably inserted into the cover part 37b from below and guided, and a pair of guide rails 37c are formed on the front of the lower half of the base plate 37a.
By engaging with the notched kite hole 36e formed in the bottom plate 36d of the knob 36c portion of the passage cover 36,
The passage cover 36 and the tip tube 35 are held vertically movably, and engagement unevenness 37e is formed on both inner surfaces of a groove 37d cut from the upper end of the base plate 37a, and a groove 37d is formed on the back surface of the upper end of the tip tube 35. A synthetic resin bifurcated spring 41 is accommodated in the pocket portion 35d that is positioned and open to both sides, and the engaging claws 41b formed on the outer surfaces of both arms 41a of the spring 41 are elastically engaged with the engaging unevenness 37e. , the passage cover 36 and the tip tube 35 are moved to arbitrary positions and locked, thereby stabilizing the spout 30 at a desired height that matches the liquid receiving container 42. The upper end portion 37f of the fixed passage cover 37 is connected to the cylindrical portion 5 formed on the lower surface of the beak-shaped portion 5a of the shoulder portion 5.
It is held by fitting into c. This fixed passage cover 37
As a result, the boundary between the passage cover 36 and the base tube 34, which is displaced up and down when the height of the spout 30 is adjusted, is completely hidden, resulting in an aesthetically elegant configuration.
Furthermore, the fixed passage cover 37 functions as a guide member for guiding the vertical movement of the movable passage cover 36 and as a positioning member for upward movement of the spout part 31 of the downward guide part B, so that a separate soil movement positioning mechanism is required. There is no need to adopt this method, and the configuration can be simplified. Note that the spring 41 may be formed of a metal wire. Of course, other methods can be used for the vertical movement structure of the tip tube 35 and its guiding method. cover 3
6 and 37 cover the downward guide path B from beginning to end without exposing it from between them due to mutual superposition even when the cover 36 moves up and down due to the height adjustment of the spout 30, thereby protecting the downward guide path from external force. It protects the device and prevents the operator's hands from touching it directly and causing heat or burns. In particular, the heat-resistant external force safety gap S between the covers 36, 37 and the guide portion B enhances such effects. In the embodiment shown in FIGS. 7 to 10, a fixed passage cover 37 is provided on the outer surface of the container body 71 and has a cover portion 37b along the entire length from the same height position as the shoulder portion 5a to the lower part of the container body 1. The base plate 37b, which is screwed 51 to the back surface of the cover part 37b, is attached to the exterior case 2 by screws 52, and covers the spout 317 of the tip tube 35 and the spout 31 of the movable passage cover 36 for the tip tube 35. The knob 36c is exposed to the outside through a vertically long window 53 provided in the front of the cover part 37b,
6 and the tip tube 35 are moved up and down within the cover portion 37b to adjust the height of the spout 30.

An auxiliary wall 36f is also provided at the bottom of the knob 36c to prevent the lower part of the window 53 from being opened and the interior to be seen when the spout part 31 is located above the window 53, and to prevent the inside from being seen. Elastic tongue pieces 36g are formed by making cuts 54 from below in both side plates, and the engagement claws 36h formed on the outer surface of the lower end of each tongue piece 36g are connected to the engagement unevenness formed on the inner surface of the side plates of the cover part 37b. By elastically engaging the spout 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 34 is formed integrally 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
After being bent almost horizontally, the remaining droplets that remain scattered in the long downward guide path B after pouring gradually join together while falling down, and when a small amount has been sent considerably, they try to flow down from the spout 30. The water is retained on the horizontal bottom surface of the spout 31, which is wider than the amount of water, by surface tension, 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. 11 to 13 show still another modification of FIG. 1, in which only one guide rail 37c is provided in the front of the lower half of the base plate 37a of the fixed passage cover 37 in a dovetail shape, This is the knob bottom plate 3 of the movable passage cover 36.
6d to guide the lower part of the passage cover 36 by engaging the dovetail cut guide hole 36e formed in the base plate 37.
The lower end 37h a is held by a presser 102 attached to the outer surface of the outer case 2 with rivets 101, making the appearance simpler than that shown in FIG. In addition, fixed passage cover 3
A W-shaped spring 103 made of a metal wire is used as a member that engages with the engagement unevenness 37e of 7 to lock the tip tube 35 in a desired position, and its central winding portion 103a is a protrusion protruding from the back surface of the tip tube 35. While engaging the shaft 104, both arms 103b are attached to the protruding shaft 10.
4. The left and right projecting pieces 105a of the T-shaped wall 105 protruding from the tip tube 35 are engaged with and held at the lower part of the 4, and the engagement claws 103c bent at the ends of both arms 103b are elastically inserted into the engagement unevenness 37e. It is engaged. Reference numeral 361 is a cutout portion of the passage cover 36 that provides a relief for the W-shaped spring 103.

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 the present invention, the downward guide path for guiding the dispensing contents to the desired height of the container includes a vertically movable part for adjusting the height of the lower end spout, and is covered by a fixed passage cover and a movable passage cover. In addition, the double force bars overlap each other due to the vertical movement of the movable passage cover as the height of the spout is adjusted.
Since the downward guide path is not exposed from between them, the downward guide path is well protected from external forces, and the danger of direct contact with the operator's hands is also avoided.

Not only is the downward guide path not exposed to the outside by both covers as described above, but there is no external break between the two covers, so the downward guide path can be adjusted depending on the specific structure, such as adjusting the height of the spout. Regardless, a simple continuous appearance can be provided by the cooperation of both covers.
