Description

[Detailed Description of the Invention] (A) Field of Application This invention relates to, for example, a pot stopper configured to open and close a valve body of a liquid discharge path formed inside the pot stopper by means of a push button.

(b) Prior art In order to enhance the heat-retaining and cold-retaining effects of the pot and to prevent the liquid from spilling out in the event of an unexpected fall, a stopper with a liquid outlet is screwed onto the upper end of the inner container. A push button provided on the stopper is operated to open the valve body of the liquid pouring path to inject liquid, and after the liquid injection is completed, the push button is operated again to close the valve body.

However, with conventional pot closures constructed in this way, people sometimes accidentally forget to close the valve after pouring liquid and leave the valve open, making it difficult to keep the contents warm or cold. The effectiveness was significantly reduced. Furthermore, when carrying the pot, the contents may unexpectedly leak out from the spout, causing problems such as the contents leaking onto clothes, furniture, etc., and in the worst case scenario, causing burns to the body. Ta.

(c) Purpose of the invention Therefore, the purpose of this invention is to provide a highly safe pot stopper that can be operated only to open the valve when dispensing, and to automatically close the valve.

(d) Structure of the device A stopper with a liquid outlet path is screwed onto the mouthpiece provided at the upper end of the pot, and the liquid outlet path inside the stopper is applied to the upward biasing force of the valve body provided at the bottom. Therefore, the pot is configured to be closed at all times and opens and closes the liquid dispensing path by pressing down a push button provided on the upper part of the valve body, and is latched to the handle side of the upper part of the outer peripheral wall of the push button. A locking piece is provided on the upper part of the stopper on the side of the locking part, and a locking piece is provided on the upper part of the stopper on the side of the locking part, which is always urged toward the push button side by a spring and engages with the locking part at the push button's pushing limit position. A groove-shaped rolling path is provided at a position substantially perpendicular to the locking tool and is sloped high enough to reach the bottom or spout side, and a groove-shaped rolling path is provided in the rolling path to detect the tilted state of the pot. A rolling motion device that rolls back and forth is provided, and a contact portion of the rolling motion device is formed at the intersection of the locking device with the rolling path, so that the pot can be erected after pouring liquid. The pot plug body is configured to allow the rolling motion to roll toward the abutting portion and to release the engagement between the locking portion and the locking piece by an impact force colliding with the contact portion. It is characterized by

(e) Effects of the invention According to this invention, the locking part of the push button and the locking tool are formed to be detachable, and a rolling motion device that detects the upright and tilted states of the pot collides with the locking tool. Therefore, when the push button is pressed when injecting liquid, the engagement part of the push button and the locking tool engage to stop the upward movement of the push button and keep the valve open to enable liquid injection. do. When the injection is completed and the pot is placed in the upright position, the rolling motion tool moves down the rolling path from the tilted position to the upright position and collides with the locking tool, causing the locking tool to rotate due to its inertia. The valve closing operation can be automatically performed by disengaging the engagement portion between the locking tool and the push button and moving the push button upward.

As a result, it is possible to reliably prevent a drop in the effectiveness of keeping the contents warm or cold due to forgetting to close the valve, water on clothing, furniture, etc., and even personal accidents such as burns, thereby further improving the safety of the pot.

A liquid pouring path 14 is formed. Furthermore, an upper lid 15 is permanently fitted and engaged with the upper peripheral wall.

At the bottom of the lower lid 9, there is a partition wall 16 at one end.
The above-mentioned liquid pouring path 14 partitioned by is formed. Further, a valve body actuating cylinder 17 is provided in the center thereof to protrude upward, and a valve body 18 is inserted into the cylinder so as to be vertically movable.

The above-mentioned upper lid 15 has a push button hole 19 formed in its center, and a push button 20 is inserted into the push button hole 19 so as to be vertically movable.

The above-mentioned valve body 18 is inserted into the above-mentioned actuating cylinder 17 and irremovably locks the above-mentioned push button 20 at its upper end, and this push button 20 and the above-mentioned lower cover 9
It is always urged upward by a spring 21 interposed between it and the bottom of the liquid spouting passage 14, thereby closing the opening hole 22 of the liquid spouting passage 14 mentioned above.

The above-described push button 20 has a groove-shaped locking portion 23 cut out on the handle 6 side of the upper portion of the outer peripheral wall thereof. Then, the push button 20 is positioned at the upper limit due to the upward biasing force of the spring 21, and the valve body 18
4 is closed from below, as shown in FIG.
5 is in pressure contact with the outer peripheral wall of the push button, and when the push button 20 is pushed down to the lower limit of movement against the spring 21 during liquid injection, it engages with the aforementioned locking piece 25, and this engagement causes the push button 20 to close. The upward movement is stopped and the open state of the valve body 18 is maintained.
