Abstract
Provided is a beverage container that includes a container main body capable of containing a beverage, a valve seat, a valve body, a seesaw member, and an operation portion. The valve seat defines a beverage spout. The valve body is disposed to be movable between a closing position for sealing the spout and an opening position for opening the spout. The seesaw member includes a first end portion, a second end portion, and a fulcrum portion, and is connected to the valve body, and is swingable using a fulcrum portion as a fulcrum. The operation portion includes a shaft portion and a lever portion. When the lever portion is rotated, the seesaw member is inclined, and the valve body is pushed up and moves from the closing position to the opening position.
Claims13
A beverage container for storing a beverage, comprising:
- a container main body capable of containing the beverage;
- a valve seat that defines a spout for pouring a beverage contained in the container main body;
- a valve body that is disposed to be movable between a closing position for sealing the spout by being in tight contact with the valve seat and an opening position for bringing the inside and the outside of the container main body into communication with each other via the spout away from the valve seat;
- a seesaw member that includes a first end portion and a second end portion that are spaced away from each other in a front-rear direction, and a fulcrum portion disposed between the first end portion and the second end portion, the seesaw member being connected to the valve body between the fulcrum portion and the second end portion, and being swingable using the fulcrum portion as a fulcrum;
- and
- an operation portion that includes a shaft portion and a lever portion that is disposed on a lower side of the first end portion and is configured to swing using the shaft portion as a rotation axis, the operation portion supporting the first end portion of the seesaw member when the valve body is located at the closing position,
- wherein, when a force is applied to the lever portion in a direction in which the lever portion is pushed up to rotate the lever portion around the shaft portion, the seesaw member rotates around the fulcrum portion and is inclined toward the first end portion, and the valve body is pushed up and moves from the closing position to the opening position.
