Problems solved by technology
[0003] During daily use, when the cup is filled with hot water, when the hot water in the thermos cup cools down after a period of time, a negative pressure is formed in the cup due to the contraction of liquid and gas, which makes it difficult or even impossible to absorb the cup lid. If it is opened, it will cause inconvenience to the user and affect the experience of the user. When the cup cover is turned with a large force, the hot water in the thermos cup will be spilled, causing a scald accident
If things go on like this, the service life of the sealing ring will be shortened, resulting in reduced airtightness of the water cup

The invention provides a thread-free portable cup, and belongs to the technical field of water cups. The problems that the temperature of water in an existing cup is reduced, a cup lid can be opened with large force, time and labor are wasted and the like are solved. The portable cup comprises a cup body and a cup lid, wherein an elastic sealing ring is arranged at the bottom of the cup lid, a pull ring is further arranged in the cup lid, and the pull ring can drive the elastic sealing ring to be extruded and deformed after being pulled upwards so that the periphery of the elastic sealing ring can abut against the wall of an inner cavity of the cup body to form circumferential sealing. The cup lid is further provided with a positioning structure used for limiting movement of the pull ring so that the pull ring can be in a locked state. The cup lid is further provided with a driving mechanism used for releasing the locking state so that the elastic sealing ring can be restored to be in a straightened state. When the pull ring is pulled upwards, the elastic sealing ring is driven to be extruded and deformed, and circumferential sealing is achieved; and when the cup needs to be opened, the first button and the second button are pressed, the cup body is held by one hand and is opened.
Description
technical field [0001] The invention belongs to the technical field of water cups, and relates to a non-threaded portable cup. Background technique [0002] At present, most of the water cups on the market are connected by threads between the lid and the cup body. A sealing ring is arranged between the lid and the cup body. After the ring is compressed and deformed, a circumferential seal is realized at the mouth of the cup body. [0003] During daily use, when the cup is filled with hot water, when the hot water in the thermos cup cools down after a period of time, a negative pressure is formed in the cup due to the contraction of liquid and gas, which makes it difficult or even impossible to absorb the cup lid. Opening causes inconvenience to the user and affects the experience of the user. When the cup cover is rotated with a large force, the hot water in the thermos cup will be spilled, causing scalding accidents. If things go on like this, the service life of the seal...
