Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pot stopper that is fitted into the mouth of a pot to open and close the mouth.

(Prior Art) A stopper for a pot generally includes a liquid outflow passage for draining the liquid in the pot, and a valve body for opening and closing the outflow passage, and the valve body is connected to an operator provided at the top of the stopper via an appropriate mechanism. The valve body is configured to open and close the outflow passage by rotating, reciprocatingly sliding, or pressing the operating element in conjunction with each other.

(Problem to be solved by the invention) By the way, when the valve body is configured to open and close by rotating the operator as described above, the valve body is opened and closed by holding the pot with one hand and rotating the operator with the other hand. If you have to open and close the pot and are trying to drain the liquid from the pot while holding the pot in one hand, put the pot down, open the stopper, and then hold the pot in your hand again. However, there was the inconvenience of having to hold the pot with the other hand to supply the liquid.

In addition, if the valve body is configured to be opened and closed by the sliding operation of the operator, it may be possible to open and close the valve body with one hand, but in reality, one-handed operation is difficult due to frictional resistance and catching on the sliding part. Yes, you have to hold the pot with one hand while sliding the controls.

On the other hand, if the valve body is configured to open and close by pressing the operator, it is more stable during operation; in other words, it is only necessary to press the operator downward, so there is no need to hold or support the pot. However, in this case, the opening/closing mechanism of the valve body has a very complicated structure, requires a high degree of precision, and is very prone to failure.

(Means for Solving the Problems) The present invention was devised to solve the above-mentioned problems, and includes a valve body that opens and closes the liquid outflow path, and a valve body that is provided with a liquid outflow path. In a pot stopper that is provided with a pusher for operating the valve body and is configured to normally bias the valve body in the closing direction by a spring, the upper end is placed along the shaft of the valve body within the body of the stopper. a flexible vertical elastic rod having a free end and a locking piece protruding toward the shaft portion of the valve body at the free end and having a fixed lower end; A side wall is formed on one side of the shaft of the body along the inner surface thereof for vertically guiding the elastic rod, and an upper wall facing the other side is connected to the upper end of the side wall. From the closed state of the valve body, move the end of the locking piece of the elastic rod from the closed state of the valve body toward the other side of the shaft of the valve body below the wall, and then touch the other side of the lower surface of the upper wall. A first cam surface is formed that is inclined diagonally upward for guiding the first cam surface, and an engaging portion that is inclined diagonally downward from the tip of the first cam surface toward the side wall is connected to the top of the engaging portion. The locking piece of the elastic rod is engaged with the locking piece of the elastic rod, and one side of the locking piece of the elastic rod can be received on the inner surface between one side of the engaging portion and the inner surface of the side wall. and forms a second cam surface for guiding the locking piece of the elastic rod from the upper wall side over the engaging portion to the first cam surface side, and the second cam surface and the engaging portion A regulating piece is formed on the lower surface of the center of the upper wall above the middle part with the other side end to once receive the locking piece of the elastic rod and prevent it from elastically restoring to the second cam surface side. It is characterized by:

(Function) Therefore, when the valve body is moved downward against the spring by the pressing operation of the pusher, the upper end locking piece of the elastic rod is guided by the first cam surface, and is bent by its elasticity, and the first cam is moved downward. It separates from the sloped upper end of the surface, instantly contacts the lower surface of the upper wall of the valve shaft, and is simultaneously received by the regulating piece. When the pressing force of the presser is weakened from this state,
The valve body moves upward, but before reaching the closed position, the locking piece of the elastic rod engages with the engaging portion to maintain the valve body in the open position.

As a result, the outflow path is released from being closed by the valve body, and liquid can be supplied from the pot.In addition, when the outflow path is closed, the locking piece of the elastic rod engages with the engaging part. When the presser is pressed again from this state, the locking piece of the elastic rod moves relatively upward along the side surface of the second cam surface, and when released from the side surface of the second cam surface, the locking piece of the elastic rod moves due to its elastic force. When it returns to the vertical state and contacts the lower surface of the upper wall above the second cam surface, and from that state the pressing force on the pusher is released, the locking piece of the elastic rod climbs over the second cam surface and returns to its original closing state. When the valve body reaches the position, the outflow passage is closed by the valve body.

(Example) An example of the present invention will be described below based on the drawings. In the figure, reference numeral 1 denotes a bottomed cylindrical plug body that can be tightly fitted into the mouth of a pot. At the same time, a rectangular fitting hole 12 is formed in the center of the bottom wall, and a shaft portion 31 of a valve body 3, which will be described later, is fitted into the fitting hole 12. A cap 2 having a cylindrical guide tube 21 in the center is fitted and fixed.

The valve body 3 consists of a shaft portion 31 and a valve plate 32 integrally formed at the lower end of the shaft portion 31. When the valve body 3 is moved upward, the valve plate 32 moves toward the outflow path 11. When the valve pair 3 is moved downward, the valve plate 32 is separated from the opening 11a of the outflow path 11 to open the outflow path 11. On the other hand, the shaft portion 3
A pusher 4, which can move up and down within the guide tube 21 of the cap 2, is connected and fixed to the upper end of the cap 1, and a spring 5 is interposed between the pusher 4 and the stopper body 1. The valve body 3 is configured to be biased in the closing direction (upward) via the pusher 4.

Therefore, the plug body 1 is provided with an elastic rod 6 parallel to the axis of the valve body 3. Specifically, within the plug body 1, a disk body 61 is attached to the shaft portion 31 of the valve body 3 through its central square hole 62.
At the same time, the hooks 63, 63 protruding downward from the disc body 61 are inserted and locked into the locking holes 14 formed in the bottom wall of the plug body 1, and the circular plate is inserted. The plate body 61 is fixed to the stopper body 1, and this disk body 6

form. The elastic rod 6 is rod-shaped,
With its fixed lower end as a fulcrum, it is flexible in the left-right direction due to its elasticity. Incidentally, this elastic rod 6 may be provided directly from the stopper main body 1 side.

On the other hand, a flat surface 33 is formed at the intermediate portion of the shaft portion 31 of the valve body 3 so as to face the locking piece 64, and an upper wall 34 and a side wall 35 are formed to surround the flat surface 33 above and on the sides. The elastic rod 6 is arranged vertically on the inner surface of the lower end of the side wall 35 when the valve body 3 is closed, and the elastic rod 6 is engaged along the inner surface of the side wall 35 during opening and closing operations. The piece 64 is vertically guided in the vertical direction.

Furthermore, the flat surface 3 below the upper wall 34
3, a first inclined diagonally upwardly extends from the inner surface of the side wall 35 toward the other side and guides the elastic rod 6 to the other side of the lower surface of the upper wall 34 while abutting the locking piece 64 of the elastic rod 6. A cam surface 37 is formed, and an engaging portion 36 that is inclined diagonally downward from the tip of the first cam surface 37 toward the side wall 35 is connected to the engaging portion 36, and a locking piece of the elastic rod 6 is attached to the engaging portion 36. 64 is configured to maintain the valve body 3 in the open position when engaged, and furthermore, along the inner surface of the side wall 35 between one side on the engaging portion 36 and the inner surface of the side wall 35. The inner surface of the elastic rod 6 can receive one side of the locking piece 64 of the elastic rod 6, and the locking piece 64 of the elastic rod 6 can be moved over the engaging portion 36 from the upper wall 34 side to the first cam. Second cam surface 3 for guiding toward surface 37 side
8 is formed. 39 is a regulating piece protruding from the lower surface of the center of the upper wall 34 above the intermediate portion between the second cam surface 38 and the other end of the engaging portion 36;
The other side surface once receives the locking piece 64 of the elastic rod 6 to prevent it from elastically returning to the second cam surface side.

In this way, the stopper of the present invention is used by tightly fitting it into the mouth of the pot, and the valve body 3 is moved downward by the pressing operation of the pusher 4 to open the opening 11a of the flow passage 11 of the valve body 3. At this time, the end locking piece 64 of the elastic rod 6 is moved to the third
From the state shown in the figure, the elastic rod 6 is guided by the first cam surface 37 to elastically deform to one side (to the left) in the lateral direction with respect to the shaft portion 31 of the valve body 3, and the locking piece 64 The upper wall 34 of the flat portion 33 is brought into contact with the upper wall 34 to restrict the downward movement of the valve body 3. When the pressing operation of the presser 4 is relaxed in such a state, the elastic rod 6 is moved to the other side (to the right) in the lateral direction with respect to the shaft portion 31 of the valve body 3 due to its elastic restoring force, as shown in FIG. Displaced to
The locking piece 64 is brought into contact with the regulating piece 39, and then the locking piece 64 is dropped into the engaging portion 36 as shown in FIG. At the same time, the valve body 3 is kept locked in the open state.

On the other hand, when closing the flow passage 11 with the valve body 3, the presser 4 is moved from the state shown in FIG.
is pressed again to separate the locking piece 64 and the engaging portion 36.
When the engagement state with the locking piece 64 is released, that is, when the valve body 3 is moved downward by the pressing operation of the pusher 4, the engaging part 36 moves downward with respect to the locking piece 64, and this locking piece 64 and the engaging part 36, the locking piece 64 of the elastic rod 6 moves relatively upward along the side surface of the second cam surface 38, and when it separates from the side surface of the second cam surface 38, its elasticity The force restores the vertical state and abuts the lower surface of the upper wall above the second cam surface 38, and from that state the presser 4
When the pressing force is released, the locking piece 64 of the elastic rod 6
passes over the second cam surface 38 and reaches the original closed position, and the outflow passage 11 is closed by the valve body 3.

(Effects of the invention) As explained above, the pot stopper according to the present invention opens and closes the outflow path by the valve body by moving the valve body up and down by pressing the pusher, and when liquid is supplied, the pot stopper opens and closes the outlet passage. There is no need to hold or support it, so-called one-handed operation is possible, and it is possible to maintain the locking of the valve body in the open position and release it smoothly and accurately with an extremely simple structure. Moreover, smooth and accurate operation can be expected without increasing the precision of each part, making it possible to reduce production costs.
