Also, the cap assembly 3 of the present embodiment, as shown in Figures 11 and 12, has a stop mechanism 36, which blocks the lower end of the cap body 10 at the plug body 29 (inner plug 12). In the side state, the rotation of the plug body 29 (inner plug 12 ) relative to the cap body 10 around the axis can be restricted.

The stopping mechanism 36 has: at least one or more (two in this embodiment) locking parts 36a, the locking parts 36a are arranged on the surface (upper surface) of the plug body 29 opposite to the cover body 10 ) side; and at least one or more (two in this embodiment) to be locked portion 36b, the locked portion 36b is set on the surface of the cover body 10 that is opposite to the plug body 29 (lower surface) side.

The locking portion 36 a is constituted by a wall protruding from the upper surface side of the plug body 29 . The locking portion 36 a extends in the diameter direction of the plug body 29 , and protrudes from the upper end of the inclined upper surface of the plug body 29 so that the height in the diameter direction is the same. In addition, the locking portion 36a is disposed at a symmetrical position across the central hole 33a of the plug body 29 .

The locked portion 36b is constituted by a partly notched groove of the lower peripheral wall 10f protruding from the lower surface side of the cover body 10 . One end (left end) of the locked portion 36 b in one direction is constituted by a vertical surface, and the other end (right end) is constituted by an inclined surface. In addition, the locked portion 36b is provided at a symmetrical position across the shaft hole 19a of the cover body 10 .

In the state where the plug body 29 (inner plug 12) blocks the lower end side of the cover body 10, by making the locking portion (wall portion) 36a engage with the locked portion (groove) 36b, the locking portion (wall portion) 36a The actuating mechanism 36 can limit the rotation of the plug body 29 (inner plug 12 ) around the cover body 10 .

Thereby, it is possible to prevent the sliding shaft 30 (inner plug 12 ) from moving against the first holding member 23 (lid) when the lid assembly 3 is rotated in the axial direction relative to the container body 2 to disassemble the lid assembly 3 . The screwing of the plug body 11) is released by rotating the plug body 29 (inner plug 12) in the axial direction.

On the other hand, in a state where the plug body 29 (inner plug 12 ) opens the lower end side of the cap body 10 , the locking portion (wall portion) 36 a is locked to the locked portion (groove) 36 b. was lifted. Thereby, the plug body 29 (inner plug 12 ) can be easily rotated relative to the cap body 10 around the axis.

In addition, when the plug body 29 (inner plug 12) is rotated in the axial direction relative to the cap body 10, in the stopper mechanism 36, the locking portion (wall portion) 36a slides into contact with the lower peripheral wall 10f. While the lower end portion of the plug body 29 is separated from the waterproof packing 20 . Thereby, the plug body 29 (inner plug 12 ) does not contact the waterproof gasket 20 , and the plug body 29 (inner plug 12 ) can be easily rotated relative to the cover body 10 in the direction around the axis.

In the stop mechanism 36, as long as the locking portion 36a is locked to the locked portion 36b as described above, the locking portion 36a is not limited to be made of a wall, and the locked portion 36b is not limited to It consists of grooves, and the structure of the locking part 36a and the locked part 36b can be changed suitably.

In the cap assembly 3 of the present embodiment having the above-mentioned structure, the flow path R can be blocked by the plug body 29 (inner plug 12 ) blocking the lower end side of the cap body 10 . From this state, the operation lever 24a can be pushed downward with the thumb or the like just by holding the handle portion 8a with one hand.

At this time, from the state where the front end portion of the slide shaft 30 is in contact with the cover member 24, the cover member 24 (cover body 11) is rotated downward against the pressure of the first coil spring 21, thereby The sliding shaft 30 (inner plug 12 ) is slid (moved) downward. Thereby, the plug body 29 (inner plug 12 ) opens the lower end side of the cap body 10 , so that the flow channel R is in an open state.

Also, when the plug body 29 (inner plug 12) receives the pressure in the container body 2, the sliding shaft 30 (inner plug 12) is slid (moved) downward to resist the force of the second coil spring 31. Pressure, the head 30b will open the lower end side of the central hole 33a, and the gas will flow through the gas flow port 18 and the inside of the container body 2.

In the cover assembly 3 of this embodiment, by tilting the container body 2 forward from this state, the beverage contained in the container body 2 can be poured out from the water outlet 15 through the open flow channel R.

On the other hand, in the cover assembly 3 of the present embodiment, the cover member 24 (cover body 11 ), which is pressed by the first coil spring 21 , rotates upward by releasing the pressing operation of the operation lever 24 a. (move). In addition, the slide shaft 30 (inner plug 12 ) pressed by the first coil spring 21 slides (moves) upward. Thereby, the plug body 29 (inner plug 12 ) blocks the lower end side of the cap body 10 , and the flow path R becomes blocked.

Also, by sliding (moving) the slide shaft 30 (inner plug 12 ) upward, the head 30 b pressed by the second coil spring 31 blocks the lower end side of the center hole 33 a.

In the cover unit 3 of the present embodiment, the flow channel forming portion 25 forming a part of the flow channel R is provided on the cover member 22 (cover body 11 ). Thereby, the beverage in the flow channel R can be prevented from flowing to the inner side of the cover body 11 (specifically, between the cover member 22 and the cover member 24 ), and the flow channel R can be kept hygienic.

In addition, in the cap assembly 3 of the present embodiment, the inner plug 12 can be freely attached to and detached from the cap body 11 in a state where the inner plug 12 opens the flow passage R. Specifically, in the state where the plug body 29 (inner plug 12) opens the lower end side of the cover body 10, the inner plug can be freely attached and detached to the first holding member 23 on the side of the cover body 11 by screwing. This slide shaft 30 on the plug 12 side.

Thus, in the cap assembly 3 of this embodiment, the cap body 11 and the inner plug 12 can be removed from the cap body 10 in a state where the plug body 29 (inner plug 12 ) opens the lower end side of the cap body 10 . The cover assembly 3 can be disassembled more easily.

Therefore, when the cover body 10 , the cover body 11 and the inner plug 12 are disassembled in the cover assembly 3 , the flow channel R can be cleaned more easily. Moreover, since the lid body 10 , the lid body 11 and the inner plug 12 are cleaned separately in the disassembled state, the sanitation among the lid body 10 , the lid body 11 and the inner plug 12 can be kept.

As mentioned above, the cover assembly 3 of this embodiment has a simple structure and is easier to clean. Therefore, the lidded container 1 of the present embodiment can be used more conveniently by having such a lid assembly 3 .

However, the present invention is not limited to the examples of the above-mentioned embodiments, and various changes can be added without departing from the spirit of the present invention. For example, in the above-mentioned embodiment, the container with cover 1 applied to the desktop thermos pot is illustrated, but as long as the container with cover 1 has the cover that is detachably installed on the container body 2 with an opening at the upper end Component 3, the present invention can be widely applied.

In addition, the above-mentioned embodiment exemplifies the container with a lid 1 that can perform a cold-keeping function with the container body 2 having a vacuum insulation structure, but it is still applicable to the container with a lid 1 provided with the container body 2 without a vacuum insulation structure. this invention.

According to, the above description is only a preferred embodiment of the present invention, but the scope of rights claimed by the present invention is not limited thereto. According to those who are familiar with the art, according to the technical content disclosed in the present invention, they can The easily conceivable equivalent changes shall all fall within the scope of protection of the present invention.
