CONTAINER CAP DEVICE WITH AUTOMATIC EVACUATION FUNCTION

WIPO Patent Application WO/2014/194508

A1

A container cap device with an automatic evacuation function comprises a container cap body (20) on which an air exhaust mechanism (30), a vacuum indication assembly (40), a first switch (50) and a second switch (60) are arranged; a control assembly is arranged with respect to the second switch (60), thus, the air exhaust mechanism (30) is controlled to be switched on or off via the first switch (50) and the second switch (60) in order to evacuate the air in the container thoroughly, and with the help of the vacuum indication assembly (40) which indicate that whether the container is in a vacuum state currently, a user can be aware of air leakage in time; and meanwhile, on the precondition that the second switch (60) is automatically controlled to be switched on or off by the control assembly (70), the air exhaust mechanism can be started up automatically to accomplish compensatory air exhaust in case of air leakage, and in this way the purpose of ensuring permanent vacuum in the container is fulfilled and the freshness-retaining and moisture-proof functions are realized in a real sense.
