Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to liquid containers such as thermos flasks.

(Prior Art) As shown in FIG. 5, a conventional liquid container has a series of liquid pouring passages 63 in a stopper body 61 as a stopper for opening and closing a liquid supply port, and a stopper for opening and closing the liquid supply port. A device is known in which valves 64 are provided to open and close the passages 63, and the valves 64 can be opened and opened from the outside by means of an operating member 65 (for example, Japanese Utility Model Publication No. 183929/1983).

However, in this conventional liquid container, the spout 82 of the liquid pouring passage 63 provided in the stopper is formed in a state that projects outward from the outer surface of the stopper main body 61 and is fixedly formed on the stopper main body 61. As a result, there have been problems in that the spout 82 gets in the way when not in use, and the packaging case becomes large, increasing costs for transportation or storage in a warehouse.

Furthermore, in the conventional liquid container shown in FIG.
The operating part of the operating member 65 for opening and closing the valve is located on the upper surface side of the stopper body 61. When dispensing liquid, after operating the operating member 65 in the valve opening direction from above the stopper main body 61, the operating member 65 is moved toward the liquid container main body side. This is done by grasping the handle (not shown) and tilting the liquid container. However, in this conventional liquid container, when operating the operating member 65 in the valve opening direction with only one hand, one finger is placed on the operating member and the other finger is used to open the liquid container. However, simply supporting the top of the liquid container with fingers other than the fingers operating the operating member during the valve opening operation deteriorates the stability of the liquid container, and on the other hand,
When supporting the liquid container with one hand and operating the operating member with the fingers of the other hand, the safety of the liquid container is improved, but there is a problem in that two hands are required to open the valve. Furthermore, when dispensing liquid, it is necessary to separately perform the work of operating the operating member and the work of holding the handle, which is unrelated to the operation member, and there is also the problem that the work of dispensing liquid becomes complicated.

(Purpose of the invention) In view of the above-mentioned problems with conventional liquid containers, the present invention was designed to
Another object of the present invention is to provide a liquid container in which the spout does not get in the way, the component configuration is simplified, and the operation when dispensing liquid can be performed easily and reliably.

(Means for Achieving the Object) The present invention provides a liquid container having a handle on the outer surface of the liquid container body and a stopper at the liquid supply port of the liquid container main body, in which a series of liquid pouring points are provided in the stopper body. A passage is provided, and the spout of the liquid spouting passage is made to be freely retractable from the plug body, and a valve for opening and closing the liquid spouting passage is provided in the middle of the liquid spouting passage, and furthermore, a valve for opening and closing the liquid spouting passage is provided in the middle of the liquid spouting passage. , an operating member is provided which integrally forms the spout and allows the protruding operation of the spout and the opening operation of the valve to be performed simultaneously from the outside; It is characterized by being located directly above and near the handle that can be operated with one's fingers.

(Function) In the liquid container of the present invention, the spout forming the tip of the liquid dispensing passage is retractable from the stopper body, so that when the liquid container is not in use or when packed, the spout By immersing the spout into the stopper body, the entire liquid container can be made compact, and when dispensing liquid, the spout protrudes to ensure ease of dispensing work. By providing an operating member that can perform the ejecting operation and the valve opening operation at the same time, even if the spout is designed to protrude when dispensing liquid, both operations (Note) can be performed with a single operation. (mouth protrusion operation and valve opening operation) can be performed at the same time. Further, since the operating portion of the operating member for opening the valve is located directly above and near the handle, the operating member can be operated while grasping the handle. Furthermore, since the spout is integrally formed with the operating member, the number of parts is reduced, and the spout reliably responds to the appearance and retraction when the operating member is operated.

(Embodiments) Several embodiments of the present invention will be described with reference to FIGS. 1 to 4. FIGS. 1 and 2 show the first embodiment of the present invention, and FIGS. The same second
and a liquid container of a third embodiment are shown.

The liquid container (thermos flask) used in the first embodiment shown in FIGS. 1 and 2 is a liquid container main body that houses an inner container 3 in an exterior body 2 consisting of an annular shoulder member 4 and a body member 5. 1, and a plug 10 for opening and closing the liquid supply port 6 of the liquid container main body 1.

A handle 7 is vertically attached to the outer surface of the exterior body 2.

In the liquid container of this first embodiment, the stopper 10
can be attached to and detached from the upper outer surface 4a of the shoulder member 4 in a one-touch manner. That is, the upper outer surface 4a of the shoulder member 4 to which the stopper 10 is coupled is formed into a substantially square shape in plan, and the upper outer surface 4a
(Fourth side) is formed with a relatively short horizontal engagement protrusion 4b. On the other hand, the outer wall 2 of the stopper 10
5 (which serves as a connecting portion to the shoulder member 4) is elastically deformable, and its inner surface is formed into a substantially square shape in plan, which is slightly larger than the upper outer surface 4a of the shoulder member 4. Furthermore, an engaging protrusion 25a is formed on the inner surface (four sides) of the outer wall 25 of the stopper, and is capable of engaging and detaching from the engaging protrusion 4b on the shoulder member 4 side. When this stopper 10 is attached to the shoulder member 4 side, the top surface of the stopper 10 is firmly pressed while the four sides of the outer wall 25 of the stopper 10 and the four sides of the upper outer surface 4a of the shoulder member 4 are aligned with each other. By pressing down, the engaging protrusions 4b, 25 on each side
a can be fitted onto the upper part of the shoulder member 4 of the stopper 10, and when the installed stopper 10 is removed, the stopper 10 is rotated within an angle range of approximately 90° relative to the shoulder member 4. By this, the engaging projections 4 on each side
b, 25a are disengaged, and the stopper 10 can be removed upward.

The plug body 11 has an upper plate portion 2 having a substantially square outer shape.
The lower member 21 is formed by integrally forming the outer wall 25 on the outer periphery of the lower member 21, and the upper member 22 is placed over the upper member 21.

A recessed portion 26 recessed downward is formed in the center of the upper plate portion 24 of the lower member 21 .

A cavity 23 is defined between the upper surface of the lower member 21 and the lower surface of the upper member 22. This vacant room 23
A liquid pouring passage 13 is formed inside the inner container 3, which communicates between the inside and outside of the inner container 3 in a closed state.

The liquid pouring passage 13 includes a water inlet 31 formed in the center of the recessed part 26 of the lower member 21, a lower surface of a stopper inner part 51 of an operating member 15, which will be described later, and an upper surface of an upper plate part 24 of the lower member 21. It is composed of a water passage 30 formed between the two, and a spout 32 formed in a tubular shape.

The spout 32 is installed so as to be freely protrusive and retractable from the outer surface of the plug body 11 in the inner and outer directions through a horizontal window hole 27 formed in the side surface of the plug body 11. Further, the spout 32 is integrally formed on the tip side (left end side) of the operating member 15, which will be described later.

The operating member 15 is formed to be horizontally long, and its operating portion 50 (the right end of the operating member 15) is connected to the stopper body 1.
It extends outward through an insertion hole 28 formed on the opposite side surface of the window hole 27 for appearing and retracting the spout in 1.

By pushing and pulling the operating portion 50 of the operating member 15, the spout 32 can be projected outward from the window hole 27 (FIG. 2) or retracted (FIG. 1). It's starting to get better. In this way, the spout 32 is connected to the operating member 1.
5, the component structure can be simplified and the spout 32 can reliably respond to the appearance and retraction when the operation member 15 is operated. Further, this operating member 15 is capable of opening and closing the valve 14, which will be described later, at the same time as the opening and closing operation of the spout 32, as will be described later.

The water port 31 is provided with a valve 14 that opens and closes the water port 31. The valve 14 is formed in a vertically oriented conical shape (tapering upwardly) with an outward flange forming a valve seat abutting portion 41 at the lower end. The valve 14 is mounted so as to be biased upward in the valve-closing direction by a spring 16 interposed between a portion near the upper end 42 and the upper surface of the recessed portion 26 of the plug body 11.
In this embodiment, the lower opening edge of the water inlet 31 serves as the valve seat 33, and the upper surface of the valve seat contact portion 41 of the valve 14 can come into contact with and separate from the valve seat 33 from below. There is.

This valve 14 is adapted to be opened and closed (valve up and down movement operation) by also serving as an operation member 15 for operating the spout 32 to move in and out. That is,
On the lower surface of this operating member 15, a high-position flat surface 5 that does not come into contact with the upper end 42 of the valve 14 is provided from the spout 32 side.
2. A downwardly inclined inclined surface 53, an upper end 42 of the valve 14;
Low level plane 5 to keep it pressed down
4 are formed sequentially. When the operating portion 50 of the operating member 15 is pulled outward (FIG. 1), the high-position plane 52 is located directly above the valve upper end 42, and the valve 14 is moved by the spring 16. When the operation part 50 is pushed and operated, the valve upper end 42 is pressed by the inclined surface 53, and then the valve upper end 42 abuts against the lower plane 54 as shown in FIG. In this state, the valve 14 is pushed down against the spring 16 (valve open position).
It is now being maintained. In addition, operation member 1
When the operating member 15 is pulled, the spout 32 is kept in the closed state, and the spout 32 is retracted, and when the operating member 15 is pushed, the spout 32 is kept in the open state, and the spout 32 protrudes at the same time. state.

This stopper 10 is attached to the upper part of the shoulder member 4 with the spout 32 facing away from the handle 7. At that time, the operating part 50 of the operating member 15 comes to protrude toward the handle 7, but the operating part 50 is located near the immediate upper part of the handle 7, and can be operated with the thumb of the hand that grips the handle 7. The portion 50 can be operated by pressing. Further, for example, when packing this liquid container, the operating section 50 is housed in the extra space of the packing case, and the operating section 50 is placed in the packing case.
There is no need to provide a special space for 0.

When dispensing liquid, the user can press the operating portion 50 of the operating member 15 with the thumb while grasping the handle 7. Therefore, when pressing the operating section 50,
Since the handle 7 is held by hand, the liquid container is maintained in a stable state. Moreover, by pressing the operating part 50 in this way, the opening operation of the valve 14 and the protruding operation of the spout part 32 are performed at the same time, and when the entire liquid container is tilted forward in this state, the contents inside the inner container 3 are The liquid passes through a series of liquid pouring passages 13 and is poured out from the spout 32 thereof. In this manner, during the liquid pouring operation, the operation member 15 and the forward tilting operation of the liquid container can be performed with only one hand, and both operations can be performed consecutively. When not in use (not injecting liquid), by pinching the operation part 50 with your fingers and pulling it outward, the spout part 32 is retracted and the valve 14 is closed at the same time.

The liquid container of the second embodiment shown in FIG. 3 shows a modification of the stopper valve 14 of the first embodiment. The valve 14 of the stopper of this second embodiment is integrally formed at the base end of the spout 32, and by pushing and pulling the operating member 15, the valve 14 is opened to the stopper main body 11.
The upper end 30a of the water passageway 30 inside can be opened and closed. In addition, in the stopper of the second embodiment, the operating member 15 (the spout 32 and the valve 14 are integrally provided) is always moved in the direction in which the spout 32 is retracted (the valve 14 is retracted) by the spring 17. When dispensing liquid, the liquid container is tilted while gripping the handle 7 and pushing the operating section 50 with the thumb against the spring 17. Note that the reference numeral 34 is a flap provided at the tip of the spout 32.

The liquid container of the third embodiment shown in FIG. 4 shows a modification of the liquid pouring passage 13 and valve 14 of the stopper of the first embodiment. In the liquid dispensing passage 13 of the stopper of this third embodiment, a downward guide passage 35 is integrally formed on the proximal end side of the spout 32, and when the operating member 15 is pushed, the guide passage 35 is opened. Lower end opening 35
a and the water inlet 31 communicate with each other. Further, the valve 14 is formed by bending a part of the lower end of the guide passage 35 laterally toward the spout 32 side, and when the operating member 15 is pulled, the valve 14 closes the water inlet 31. The upper opening edge is closed. In addition, in the stopper of this third embodiment as well, the operation member 1 is
5 is forcibly biased in the spout recessing direction by a spring 17.

In the second and third embodiments described above, the members having the same reference numerals as those in the first embodiment (Figs. 1 and 2) have the same functions as those in the first embodiment. , and the explanation of the first embodiment is used.

(Effect of idea) The liquid container of the present invention has the following effects.

(1) Spout part 3 of liquid pouring passage 13 formed in the stopper
2 can be freely retracted from the stopper body 11,
By immersing the spout 32 into the stopper body 11 when the liquid container is not in use or when packed, the spout 32 does not get in the way and the entire liquid container becomes compact. This allows the packaging case to be made smaller.
Thereby, transportation costs, storage costs, etc. can be reduced.

(2) By causing the spout 32 to protrude outward from the stopper body 11 when dispensing liquid, ease of dispensing work can be ensured even with the compactly constructed stopper as described above.

(3) Since the protruding operation of the spout 32 and the opening operation of the valve 14 can be performed simultaneously by a single operation of the operating member 15, the spout 32 is made to protrude when pouring out liquid. Even if it is structured, there will be no increase in operations.

(4) Since the spout 32 is integrally formed with the operating member 15, the component configuration can be simplified, and the spout 32 can reliably respond to the appearance and retraction when the operating member 15 is operated.

(5) Since the operating portion 50 of the operating member 15 is located directly above and near the handle 7, the operating portion 50 can be operated with the fingers of the hand gripping the handle 7, so that when operating the operating portion 50, the liquid container Furthermore, following the operation of the operation part 50, the liquid container can be tilted continuously with only one hand, and the liquid pouring operation can be performed easily.
