DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water bottle and a portable liquid container such as a heat insulating container having a heat insulating structure or a double structure.

[0002]

2. Description of the Related Art Portable liquid containers having various structures are known, but the one to which the present invention is directed is to provide a liquid flow path inside and a liquid flow path inside the plug hole of the container body. A plug body provided with a valve mechanism section for opening and closing is attached, and as the valve mechanism section of the plug body, a valve opening operation section and a valve closing operation section are provided on the upper surface of the plug body, and in particular, a valve closing operation section. Is designed to make it convenient to close the valve by projecting it onto the upper surface of the plug when the valve is opened (Japanese Utility Model Publication No. 2-20976).

Further, in particular, the portable liquid container having the above-mentioned structure is provided with a cup-type lid (cup body) so that it is convenient for drinking portable beverages and the cup body is capped. Also, it is known that even if the cup body is attached in the valve open state, the valve body operates the valve closing operation portion to cope with forgetting the valve closing operation (actual fair 2
-43327).

[0004]

As described above, when the valve closing operation portion projects above the plug body when the valve is opened, the valve closing operation is convenient and there is an advantage that the valve can be closed by mounting the cup body. However, since the protruding state is maintained when the valve is opened, the valve may be closed if the valve closing operation member is inadvertently touched, such as when pouring the internal liquid into the cup. Therefore, the present invention proposes a portable liquid container that notifies a user that the cup body is mounted in the valve open state, and that employs a stopper provided with a protection portion that prevents the valve closing operation portion from inadvertently operating. .

[0005]

A portable liquid container according to the present invention has a plug body screwing portion and a large diameter below the plug body screwing portion on an outer peripheral portion of a plug hole opened at an upper portion of a container portion. A plug body having a container body provided with a cup screwing portion, a mounting portion to the plug body screwing portion, and a liquid flow passage and a valve mechanism portion for opening and closing the flow passage, and a plug hole. It is composed of a cup body that covers the entire plug body attached to the cup and can be attached to the cup screwing part.The valve mechanism part of the plug body is provided with a valve closing operation part that projects to the upper surface of the plug body when the valve is opened. Around the valve closing operation part, a protection part that does not operate and operates only in accordance with the operation of the valve closing operation part, protrudes more than the valve closing operation member, and protrudes to a position that prevents mounting of the cup body. It is characterized by being attached.

[0006]

[Function] Pour a portable beverage into the container body, attach the stopper to the stopper hole, cap the cup and carry it, remove the cup at the time of drinking and operate the valve opening operation part to flow. Open the passage and pour the internal beverage into the cup body. Especially in this valve open state, the valve closing operation part projects to the upper surface of the plug body, but the protection part further projects to the surrounding portion, so the valve closing operation part does not operate by itself. Is blocked. Further, even if the cup body is mounted on the container body in the valve-opened state, the mounting is prevented because the protective portion projects. The valve closing is closed only by operating the valve closing operation unit.

[0007]

EXAMPLES Next, examples of the present invention will be described. The portable liquid container shown in the embodiment has a container body A, a stopper B, and
It is composed of a cup body C. The container body A has a container part 1 made of stainless steel and having a double structure, a plug hole 2 opened at the upper part of the container part, and a plug screwing part for mounting a plug B on the outer periphery of the plug hole 2. 3 and the plug body screwing portion 3 below the plug body screwing portion 3.
And a cup screwing portion 3a having a larger diameter.

The plug B is a body 4 which is tightly fitted in the plug hole 2.
The attachment part 5 to the plug threaded part 3 and the spout 6 inside.
1 is provided with a liquid flow path 6 that communicates with the valve opening 62, and a valve mechanism portion 7 that opens and closes the valve opening 62. The valve mechanism 7 includes a valve body 71 that opens and closes the valve opening 62, a spring 72 that biases the valve body 71 in the closing direction, a seesaw body 73 that presses down the valve body 71 on one side, and the seesaw body. One side of 73 is provided with a valve opening operation part 74 which is regulated so that it can be pressed down only in a vertical movement, and the other side of the seesaw body 73 is connected by a narrow window crank mechanism, and the valve closing operation part 74 is also provided. Similarly, the valve closing operation part 75 and the protection part 76 are provided so as to be restricted only in the vertical movement. In particular, the valve closing operation part 75 and the protection part 7
6, the protective portion 76 is provided so as to surround the outer peripheral portion of the valve closing operation portion 75, and the protection portion 76 is always closed.
5, the upper end of the seesaw body 75 is projected upward. For connection with the seesaw body 75, the connection shaft 731 laterally projecting on the other side of the seesaw body 73 is connected to the valve closing operation part 75 and the protection shaft. The thin windows 761 of the protection part 76 are inserted through the connection thin windows 751, 761 provided below the part 76.
Is formed in an L shape in which a portion of the seesaw body 73 on the rotation axis side is gouged upward (gouged upward 762).

The cup body C covers the entire plug body B mounted in the plug hole 2 so that it can be mounted on the cup screwing portion 3a. Particularly, in relation to the protection portion 76 of the valve mechanism portion 7, In the state where the protection portion 76 is in the valve open state and protrudes above the upper surface of the plug body B, the cup body C is prevented from being screwed into the cup screwing portion 3a.

Thus, the portable beverage is poured into the container main body A, the stopper B is attached to the stopper hole 2, the cup C is capped and carried, and the cup C is removed when drinking and the valve is opened. Operation unit 74
Is operated to open the valve port 62 and pour the internal beverage into the cup body C through the pouring port 61 to be used for drinking.

That is, when the valve opening operation portion 74 is pressed down, the seesaw body 73 is rotated and the valve body 71 is moved downward against the biasing force of the spring 72 to open the valve opening 62. At the same time, since the other side of the seesaw body 73 moves upward, the valve closing operation unit 75
Also, the protection part 76 also moves upward due to the connection between the connection shaft 731 and the narrow windows 751 and 761, and the connection shaft 731 is further moved upward.
62 enters and enters a lock state in which the seesaw body 73 is prevented from rotating, and the valve open state is maintained. And when closing the valve,
The seesaw body 73 is rotated (naturally closed by the urging force of the spring 72 by releasing the locked state) by closing the valve by closing the valve closing operation portion 75 protruding from the upper surface of the stopper B.
Further, even if the protective portion 76 is pressed down by itself, since the connecting shaft 731 is fitted in the upper hollowed portion 762, its downward movement is prevented, and the protective portion 76 is attached to the outer peripheral portion of the valve closing operation portion.
Since it projects above the valve closing operation part 75, the valve closing operation part 75 is protected by the protection part 76, and it is possible to prevent a situation in which the valve closing operation part is inadvertently operated. Also, even if the cup body C is mounted on the container body A in the valve open state, the protection portion 73 projects to prevent the cup body C from being screwed into the cup screwing portion 3a. It is prevented that the cup body C is accidentally attached as it is.

The present invention is based on a structure for restricting the operation of the operating member in the valve mechanism, and the specific structures of the valve port and the valve body can be arbitrarily determined.

[0013]

As described above, the present invention comprises a container body,
In a portable liquid container including a cap body having an opening / closing valve mechanism mounted in a cap hole of a container body and a cup body capped on the cap body, particularly in a valve mechanism part, a top surface of the cap body when the valve is opened. The valve closing operation part that protrudes into the vicinity of the valve opening operation part and the protection part that does not operate independently and protrudes from the valve opening operation part are provided around the valve opening operation part. This prevents an inadvertent operation, and prevents the cup body from being accidentally attached while the valve is still open.
