Abstract: A cup lid that enables single-handed operation, including a main lid body and an auxiliary lid body. The main lid body seals an opening of a container and has a circular recess, a water passing hole, an air vent, and at least one limiting flange. The auxiliary lid body is rotatably disposed on the circular recess and has at least one limiting groove, at least one cutaway portion, a water passing port, and an air guide slot in communication with the atmosphere. Each limiting flange enters a corresponding limiting groove via a corresponding cutaway portion and is slidably received therein. The water passing port opens and closes the water passing hole as the auxiliary lid body rotates, and the air vent is slidably received in the air guide slot.

Abstract: A thermo container structure convenient to be stored, provides good thermal insulation effect and achieves stable support after being unfolded, including an outer container and an inner container; the outer container has a first body and a first cover; both filled with thermally insulated materials; the inner container has a second body and a second cover; the first body and the second body are both compressible and foldable structures, and the first body and the second body are foldable towards two different folding directions perpendicular to each other; in an unfolded state of the thermo container structure, the first cover can close against an opening of the first body, and the second cover can close against an opening of the second body.

Abstract: A cup lid that facilitates convenient operation by allowing effort saving opening of a water passing hole by using only one hand, wherein the cup lid has a main lid and an auxiliary lid; an upper surface of the main lid has the water passing hole and an air vent; the auxiliary lid is rotatably mounted on the upper surface of the main lid, and being axially limited with respect to the main lid. Rotation of the auxiliary lid will cause a water passing port disposed thereon to open or close the water passing hole; the auxiliary lid also has an air guide slot in which the air vent can slide therein when the auxiliary lid rotates, and the air guide slot is in communication with an external environment. A container using the cup lid is also provided.

Abstract: A frame for a pull-rod luggage case, including pair of pull rods parallel to each other, a pair of castor seats, an upper beam, a lower beam, and a handle; each of the pull rods at least includes an outer rod and an inner rod telescopically positioned in and out of the outer rod; a lower end of each outer rod is connected to a corresponding castor seat; each of two ends of the handle is fixedly connected with an upper end of a corresponding inner rod; outer rods, the upper beam, and the lower beam define a skeleton.
