Double-layer tea caddy

Abstract

The invention discloses a double-layer tea caddy. The double-layer tea caddy comprises an outer caddy body and an inner caddy body, wherein supporting rods are arranged at the bottom part and the sidewall of the outer caddy body; the inner caddy body is fixed to the supporting rods; the inner wall of a caddy body is arranged at the upper end of the outer caddy body, and a caddy cover consisting ofan outer wall of a cover body and an inner wall of the cover body is arranged on the inner wall of the caddy body; a sealing ring is arranged on the inner wall of the cover body; an air pumping chamber is formed in the middle part of the caddy cover, and an air pumping hole is formed in the bottom part of the air pumping chamber; a second one-way valve is arranged at the air pumping hole; a hollow tube is arranged in the air pumping chamber, and a piston ring sleeves the outer wall of the hollow tube; a pressing cap is arranged on the top part of the hollow tube, and an air exhausting hole isformed in the sidewall of the upper end of the hollow tube; a rubber ring is arranged on the outer wall, below the air exhausting hole, of the hollow tube; a plurality of air suction holes which areprovided with first one-way valves are formed in the bottom part of the hollow tube; a pressing block is arranged at the bottom part of the hollow tube. The tea caddy is high in heat insulation performance, and simple to use; most of the air in the outer caddy body can be pumped out, thus the tea is delayed to oxidize, and as a result, the freshness lifetime of tea is prolonged; and the double-layer tea caddy is applicable to refreshing storage of the tea.

Description

technical field [0001] The invention relates to the field of container packaging, in particular to a double-layer tea can. Background technique [0002] The tea cans used in daily life are all ordinary tin cans, paper cans and plastic bags, but the preservation effect of tea is still unsatisfactory, and it is prone to qualitative change. Tea cans, these cans are pushed by the lid box of the can lid to release the air in the can, it is difficult to make the can have a high degree of vacuum, the heat insulation effect is poor, the tea leaves are easily oxidized, the oxidation of the tea leaves is solved, and the intrusion of external heat is blocked. It is the primary means of keeping fresh, so there is an urgent need for a tea can with low production cost, good heat insulation effect, and a certain degree of vacuum. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a double-layered tea can to solve the above-mention...

AI Technical Summary

Problems solved by technology

[0002] The tea cans used in daily life are all ordinary tinplate cans, paper tube cans and plastic bag packaging, but the fresh-keeping effect of tea leaves is still unsatisfactory, and qualitative changes are prone to occur. At present, there are improved methods to extend the storage time of tea leaves on the market. Tea cans, these cans are pushed by the lid box of the can to release the air in the can, it is difficult to make the can have a high degree of vacuum, the heat insulation effect is poor, the tea is easy to oxidize, solve the oxidation of the tea, and block the intrusion of external heat It is the primary means of keeping fresh, so there is an urgent need for a tea canister with low production cost, good heat insulation effect, and can maintain a certain degree of vacuum.
