A leg structure supports in an upright position a container having a piping port in the bottom of the container. The leg structure is provided with fixed legs fixed or removably mounted to the container, a movable leg capable of moving relative to the fixed legs so as to approach and be separated in the horizontal direction from the fixed legs while supporting the container, and the connecting section for connecting the container and the fixed legs to each other such that the container is maintained upright relative to the fixed legs.

1. A leg structure that supports in an upright posture a container having a tubing port in a bottom portion thereof, comprising: a fixed leg fixed or removably mounted to the container;a movable leg capable of moving relative to the fixed leg so as to approach and be separated in a horizontal direction from the fixed leg while supporting the container; anda connecting section for connecting the container and the fixed leg to each other, such that the container is maintained in the upright posture relative to the fixed leg,a hinge member disposed at a higher position than the tubing port;a movable portion that extends in a circumferential direction around the container and is rotatable about a vertical axis at the hinge member,wherein the movable leg is fixed to the movable portion,wherein as the movable portion rotates, an interval between the movable leg and the fixed leg changes, andwherein in a state in which the container is supported by the leg structure, the container is fixed in the upright posture, and the fixed leg and the movable leg are arranged around the tubing port. 2. The leg structure according to claim 1, further comprising a surrounding member that surrounds the container and is ring shaped, wherein the surrounding member includes a fixed portion to which the fixed leg is connected and that extends in the circumferential direction along an outer surface of the container, a movable portion to which the movable leg is connected and that extends in the circumferential direction along the outer surface of the container, and the hinge member, which connects the movable portion rotatably with respect to the fixed portion, andwherein the connecting section is disposed on a side surface of the container, and includes an engagement member, which hooks onto the fixed portion from above, so as to support the container in the upright posture. 3. The leg structure according to claim 2, wherein the surrounding member includes a stopper for restricting rotation of the movable portion such that the movable leg cannot be opened beyond a predetermined angle. 4. A leg structure that supports in an upright posture a container having a tubing port in a bottom portion thereof, comprising: a fixed leg fixed or removably mounted to the container;a movable leg capable of moving relative to the fixed leg so as to approach and be separated in a horizontal direction from the fixed leg while supporting the container;a connecting section for connecting the container and the fixed leg to each other, such that the container is maintained in the upright posture relative to the fixed leg; anda surrounding member that surrounds the container,wherein the surrounding member includes a fixed portion to which the fixed leg is connected, a movable portion that extends in a circumferential direction around the container and to which the movable leg is connected, and a hinge member, which is disposed at a higher position than the tubing port and connects the movable portion rotatably about a vertical axis with respect to the fixed portion,wherein as the movable portion rotates, and interval between the movable leg and the fixed leg changes, andwherein the connecting section is disposed on a side surface of the container, and includes an engagement member, which hooks onto the fixed portion from above, so as to support the container in the upright posture. 5. The leg structure according to claim 4 wherein the surrounding member includes a stopper for restricting rotation of the movable portion such that the movable leg cannot be opened beyond a predetermined angle. 6. The leg structure according to claim 1, wherein the leg structure takes a first state in which the movable leg is closed, and a second state in which the interval between the movable leg and the fixed leg is wider than the first state, wherein in the first and second states, the fixed leg stays at the same position and takes the same posture with respect to the container, andwherein when the leg structure changes from the first state to the second state, the movable leg as a whole moves away from the container. 7. The leg structure according to claim 4, wherein the leg structure takes a first state in which the movable leg is closed, and a second state in which the interval between the movable leg and the fixed leg is wider than the first state, wherein in the first and the second states, the fixed leg stays at the same position and takes the same posture with respect to the container, andwherein when the leg structure changes from the first state to the second state, the movable leg as a whole moves away from the container.
