Description

Tea packing box with exhaust function

Technical Field

The utility model relates to a tea packing box.

Background

The tea preservation device is an important means for guaranteeing the quality of tea, and if the temperature of the tea is too high, the tea can be accelerated to deteriorate, meanwhile, the tea is also dried and preserved in an isolated mode, and the tea is very easy to react with oxygen in the air or absorb moisture in the air to generate deterioration. And is also particularly important for light-proof preservation and odor-proof preservation. The proper tea leaves can be preserved to keep the original taste, flavor and quality. There are various methods for preserving tea leaves, for example, the tea leaves can be prevented from being stored in a vacuum preserving device, and thus the tea leaves can be isolated from the outside air, but the tea leaves are generally difficult to realize. The drying agent can be placed in the storage device, so that moisture in the tea can be absorbed, the storage effect is good, and the method cannot remove gaseous substances such as oxygen and the like. The problem of keeping is mainly solved from improving the leakproofness to common save set, for example patent CN201999323U proposes a tealeaves packing carton, including tealeaves box body, sealing washer, tealeaves lid, the tealeaves lid cup joint in the upper shed of tealeaves box body, the tealeaves box body upper shed is equipped with the recess of cup joint sealing washer, is provided with the sealing washer in tealeaves box body and tealeaves lid junction. CN201999323U is provided with the sealing washer in tealeaves box body and tealeaves lid junction, has improved save set's leakproofness.

The above-described conventional tea leaf preservation device is suitable for long-term preservation, and is not suitable for household use. When the tea packaging device is used in home, the tea packaging device is generally opened for multiple times, part of tea is taken out, then the tea packaging device is closed or sealed, air inevitably enters the storage device in the process, air cannot be discharged, and then the tea cannot be better isolated from oxygen, water and the like in the air. There is a need for a tea leaf preservation device that can vent air well after multiple openings of the preservation device.

Disclosure of Invention

The utility model provides a tea preservation device which can well exhaust air after a preservation device is opened for a plurality of times,
