Detailed Description of the Invention Technical Field The present invention relates to a liquid container such as a thermos flask whose contents are dispensed by a manual or electric pump. The present invention relates to a spout J device for a liquid container, which is provided with a downward guide path having a vertically moving part that guides the discharged liquid downward from the upper part of the container body and adjusts the height of the lower end spout.

The prior art downward guide path tends to have a complicated structure due to its vertical movement structure for adjusting the height of the lower end spout, which spoils its appearance and is easily damaged by external forces.

In particular, note: the support of the downward moving part of the downward guideway for adjusting the exit height tends to be unstable. An object of the present invention is to provide a spout device for a liquid container that can solve the above-mentioned conventional drawbacks by providing a cover and a guide structure that can protect the downward guide path in an attractive manner and stabilize the vertically moving part. With the goal.

Structure In the present invention, in a liquid container equipped with a content liquid dispensing pump and a dispensing channel for guiding the content dispensed by the content dispensing pump to the outside of the container, the liquid container is located at the front of the container body and passes through the dispensing channel. There is a downward guide path with a vertically moving part that guides the dispensing content downward from the top of the container and adjusts the height of the lower end spout, and a downward guideway located at the front of the container that guides the liquid from the top of the container downward and adjusts the height of the lower end spout. A downward guide path cover that covers so as not to obstruct the movement of the downward guide path, and a panel member that is provided on the outer surface of the front part of the vessel body, has a guide portion for the vertically moving part of the downward guide path, and serves as a substrate of the downward guide path cover. It will be done.

The lower end of the working downward guide path has its lower end spout adjusted in height to guide the liquid to be poured to a desired height of the container body. A complicated structure with a vertically moving part for adjustment should not be exposed, and should be covered so that external forces do not directly act on it or it is not directly touched by hands, etc.

The panel member has an arbitrary width and can be stably attached to the vessel body, guides the downward moving part of the downward guideway with the guide part provided over the necessary range, and also guides the downward guideway cover over the necessary range. may be provided. Embodiment The embodiment shown in FIGS. 1 to 6 will be described. Reference numeral 1 denotes a liquid container body, forming a thermos flask in which a double vacuum bottle 3 is housed inside an outer case 2.

A saucer-shaped shoulder 5 having a hot water supply port 4 communicating with the top opening of the bottle 3 is fixed to the upper end of the outer case 2, and a lid 7 with a built-in manual air pump 6 is disposed on the shoulder 5. It is pivoted 8 to the rear part of the shoulder part 5 and configured to be openable and closable. The lid 7 has an operating portion 9 protruding from its front surface, a lock lever 12 which is pivotally connected to the lid 7 by a pin 10 and biased counterclockwise by a spring 11.

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

This has a structure in which, by pressing down on the pressing plate 25, the operating rod 28 is moved downward via the spring 29, and the valve 18 is pressed down at its lower end, 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.
The partially open hole 36C'' opened in the top plate 36b of 6a is elastically fitted into the groove 35c formed between the upper end flanges 35a and 35b of the vertically movable tip tube 35.
The lower half covers the spout part 31 and serves as an operation knob 36c for adjusting the height of the spout 30. On the outer surface of the vessel body 1, there is a vertically long panel member 3.
7 is fixedly installed by attaching its lower end to the case 2 with screws 38, and engaging the protrusion 39 at the center into the hole 40 of the case 2.

A downward guide path cover portion 37a integrally formed on the upper half of this panel member 37 is intended to cover the downward guide path B. Further, the upper half 36a of the movable passage cover 36 is slidably inserted into the cover part 37a from below and guided, and a pair of guide rails 37b formed on the front of the lower half of the panel member 37 are movable. Passage cover 36
By engaging with the notch hole 36e formed in the bottom plate 36d of the knob 36c, the movable passage cover 3
6 and the vertically movable tip tube 35 are held vertically movably, and engagement unevenness 37d is formed on both inner surfaces of a groove 37c cut from the upper end of the portion facing the cover portion 37a of the panel member 37, and the vertically movable tip tube 35 is held vertically movably. The groove 3 is formed on the back surface of the upper end of the tip tube 35.
A synthetic resin bifurcated spring 41 is accommodated in a pocket portion 35d that is located inside 7c and is open to both sides, and both arms 41 of the spring 41 are
a The engagement pawl 41b formed on the outer surface is connected to the engagement unevenness 37d.
By elastically engaging the movable passage cover 36 and the vertically movable tip tube 35, the movable passage cover 36 and the vertically movable tip tube 35 are moved to an arbitrary position and locked, and the spout 30 is stabilized at a desired height that matches the liquid receiving container 42. There is. The upper end portion 37e of the cover portion 37a 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.

By this cover part 37a, the boundary part between the movable 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 elegant configuration in appearance. can. Furthermore, since the cover part 37a functions as a guide member for guiding the vertical movement of the movable passage cover 36 and as an upward positioning member for the spout part 31 of the downward guide part B, a separate upward movement positioning mechanism is adopted. This is not necessary 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. Even when the covers 36 and 56 move up and down due to the height adjustment of the spout 30, the covers 36 and 56 cover the downward guide path B from beginning to end without exposing it even from between them due to mutual superposition, thereby protecting the downward guide path B from external forces. This prevents the hands of operators, etc. from touching directly and causing heat or burns. In particular, the heat-resistant external force safety gap S between the covers 36, 56 and the guide portion B enhances such effects. Figure 7 to 1
In the embodiment shown in FIG. 0, a panel member 57 having a separate downward guide path cover 56 is provided on the outer surface of the vessel 1 along the entire length from the same height as the shoulder 5a to the bottom of the vessel 1. A panel member 57 with a cover 56 fixed with screws 51 is attached to the exterior case 2 with screws 52, and a knob that covers the spout portion 31 of the tip tube 35 and the spout portion 31 of the movable passage cover 36 for the vertically movable tip tube 35 is attached. 36c, cover 56
The movable passage cover 36 and the upper and lower movable tip tubes 35 are exposed to the outside through a vertically long window 53 opened in the front of the cover 5.
The height of the spout 30 can be adjusted by moving it up and down within the spout 6.

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 the side plates of the wall 36f, and the engagement claws 36h formed on the outer surface of the lower end of each tongue piece 36g are connected to the engagement claws 36h formed on the inner surface of the side plates of the cover 56. By elastically engaging the unevenness 58,
The spout 30 is configured to be locked at an arbitrary height. The movable passage cover 36 and the vertically movable tip tube 35 are secured with screws 5.
5 so that they can move up and down in one piece.

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 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. 30
The water that is about to flow down is retained by surface tension on the horizontal bottom surface of the spout 31, which is wider than 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
Still another modification of FIG. 1 is shown, in which only one guide rail 37b is provided in the front of the lower half of the panel member 37 in a dovetail shape, and this is formed on the bottom plate 36d of the knob portion of the movable passage cover 36. The dovetail cut guide hole 36e is engaged to guide the lower part of the movable passage cover 36, and the lower end 37f of the panel member 37 is attached to the outer surface of the exterior case 2 with the rivets 101.
It is held by a presser 102 attached by a screwdriver, and has a simpler appearance than the one shown in FIG.

In addition, a member that engages with the engagement unevenness 37d of the panel member 37 and locks the vertically movable tip tube 35 at an arbitrary position is made of a metal wire into a W-shaped spring 103, and its central winding portion 103a is used as a downward guiding tip. 5 engages the protruding shaft 104 protruding from the back surface of the tube 35, and engages and holds both arms 103b with the left and right protruding pieces 105a of the T-shaped wall 105 protruding from the vertically movable tip tube 35 below the protruding shaft 104. Engagement claws 103c bent at the ends of both arms 103b are elastically engaged with the engagement projections 37d. 36f is a W-shaped spring 103 of the movable passage cover 36
This is a notch that provides relief from the damage.

Furthermore, the O-link 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 part 5! However, liquid leakage from the opening 32 is prevented, and the other configurations are largely different from those shown in FIG. 1, and a description thereof will be omitted. Effects According to the present invention, the downward guide path has a vertically movable part that can adjust the height of the lower end spout and pour out the liquid content at a desired height of the container, but it is covered with a passage cover, which reduces the appearance of the container. There is no damage to it, and it is protected from external forces.

It also prevents the operator from touching the device directly with his/her hands and getting burnt. Since the downward movement part of the downward direction guide path is guided by the guide part on the panel member that can be stably attached to the vessel body with a desired width, the guidance can be stably obtained within the necessary range, It does not break down or get damaged due to slight external forces such as rattling or getting caught in handling, and its durability is improved. Furthermore, the panel member serves as a base for the passageway cover as well as for providing other necessary accessories.
