Abstract

The present disclosure relates to a soup cup for maintaining a high sealing property. The soup cup includes a cup body; a compartment; an upper cover; a vertical wall; and an oil seal spring. When the upper cover is clamped to the cup body, primary sealing of the soup in the cup body can be completed, and then the sealing rubber film at the bottom of the upper cover can perform secondary sealing on the cup body; and moreover, the oil seal spring is embedded inside the sealing rubber film, and the oil seal spring expands to achieve tertiary sealing, thereby effectively preventing unfirm attachment between the upper cover and the cup body from caused by excessively long time, eliminating heat loss and liquid overflow caused by existence of various gaps, maintaining a high heat retention effect, and simultaneously creating a desirable use feeling for a holder.
