Description

[Detailed Description of the Invention] (a) Field of Application This invention relates to a pot stopper configured to open and close a liquid outlet passage formed inside the pot stopper using a valve body.

(b) Prior art Pots are designed to keep the inner container tightly sealed at all times by screwing a stopper into the upper end of the inner container in order to enhance its heat-retaining and cold-retaining effects and to prevent the contents from leaking out in the event of an unexpected fall. However, when dispensing the liquid content, operate the operation button located at the center of the stopper to open the liquid dispensing path formed inside the stopper, and pour the liquid into the pot through this liquid dispensing path. It is configured to pour out to the outside.

However, due to the structure of the conventional pot stopper mentioned above, the operation button is located in the center of the upper end.
The handle of the operating button was too far away from the handle, making it impossible to operate the operating button with the fingers of the hand holding the handle.

For this reason, when pouring liquid, the user is forced to perform two operations that normally require both hands: first operate the operation button to open the liquid dispensing path, then grasp the handle and lift the pot to pour out the contents. Ta.

Therefore, the operability of pouring liquid into the pot is poor, and if one hand is occupied and the other hand is used to operate the operation button of the pot to inject liquid, the pot becomes unstable because the hand cannot be placed on the pot. Therefore, there was a risk of the pot accidentally tipping over during operation.

This dangerous situation can be prevented by directly operating the operation button with the fingers of the hand that is gripping the handle.

(c) Purpose of the invention Therefore, the purpose of this invention is to provide an inexpensive pot stopper that has a simple structure with few components, can be safely injected with just one hand, and has little risk of tipping over. .

(d) Structure of the device In this device, a stopper with a liquid spouting path is removably screwed onto the mouthpiece provided at the upper end of the pot. A stopper for a pot that is opened and closed by a lever and a valve-closing lever, and a locking piece that is always elastic in the engagement direction is integrally protruded upward on the inner surface of the lower lid of the stopper;
The valve opening lever is formed with a pressing part that opens the valve body by a pressing operation, and a locking protrusion that engages with the locking tool and maintains the pressed state by locking the locking tool. The pot stopper is characterized in that it has a locking/disengaging surface that engages and disconnects the locking piece and the locking protrusion by a pressing operation.

(E) Effect of the invention According to this invention, the valve opening and closing levers are respectively arranged near the handle on the outer periphery of the upper end of the stopper, and these valve opening and closing levers can be moved by the fingers of the hand grasping the handle. Since the structure is configured so that the liquid dispensing channel can be opened and closed by operating the pot, the liquid dispensing operation can be performed with a single touch, improving operability and ensuring safety of the pot by preventing accidental tipping during operation. It has further improved.

Moreover, in this design, the locking piece that maintains the valve open state when the valve opening lever is pressed is formed so as to integrally protrude upward from the inner surface of the lower lid of the stopper, and the elastic force of the protruding locking piece itself is utilized. As a result, there is no need for a locking device made of a separate member whose lower end is pivotally connected, as well as a pin or spring for pivotally connecting this locking device, and the work of assembling these can also be omitted.
The structure is simple, assembly work is easy, and costs can be reduced.
