Vacuum Juice Cup

Abstract

A vacuum juice freshness-preserving cup comprises a cup body (1) and a cup lid (2). The cup lid (2) comprises an upper lid portion (40) and a lower lid portion (31). A first air hole (32) is arranged at the lower lid portion (31). A first through hole is arranged at the upper lid portion (40). An air pump (7) is provided at the cup lid (2). The air pump (7) comprises a positioning casing (80), an inner casing (70), and an outer casing (60). A pressing handle (50) is provided at the air pump (7). Air inside the cup (1) is evacuated by pressing the handle (50). When the pressing handle (50) is pressed, the air pump (7) extracts air from the cup (1). When the pressing handle (50) moves back to an original position, the air inside the air pump (7) is discharged. The juice freshness-preserving cup achieves a high degree of vacuum, and exhibits favorable freshness preserving performance.

Description

technical field [0001] The invention relates to a storage container, in particular to a vacuum preservation cup. Background technique [0002] When food and beverages come into contact with air, they are easily oxidized by oxygen in the air, resulting in corrosion and deterioration. In order to prolong the storage time of food and beverages, people often store the above-mentioned substances in closed containers. But, still have the existence of air in the existing closed container, still can produce corrosive action, make the storage time of food and beverage not long, and the quality of fresh-keeping is also unreliable. [0003] An existing fresh-keeping cup is provided with an air suction port on the lid of the fresh-keeping cup. The air suction port has a self-sealing function. An air pump is connected to the air suction port to extract the air in the fresh-keeping cup, thereby realizing vacuum preservation. However, this kind of fresh-keeping cup needs to be vacuumized...

AI Technical Summary

Problems solved by technology

However, this kind of fresh-keeping cup needs the help of an air pump to achieve vacuuming, which is very inconvenient to carry

[0004] In order to solve the problem of inconvenient carrying of the above-mentioned air pump, there is an existing vacuum fresh-keeping cup with an air pump on the cup cover, press the air pump to discharge the air in the air pump, and after releasing it, the air pump returns to its original position under the elastic force of the spring. The air pump is sealed with the outside world during the recovery process, and the internal space of the air pump becomes larger, and the gas in the fresh-keeping cup is pumped into the air pump. The valve is automatically closed, press the air pump again, and the air in the air pump is discharged, and so on, the air in the fresh-keeping cup is continuously discharged

[0005] Since the air in the fresh-keeping cup is only drawn out when the air pump is restored, the vacuuming ability of this vacuum fresh-keeping cup depends on the spring force of the spring in the air pump. Self-friction, and to overcome the atmospheric pressure, therefore, a spring with a large elasticity is required to meet the requirements, which is very laborious for the user and the user experience is not good

Moreover, the user cannot perceive the degree of vacuum in the fresh-keeping cup through the pressure of pressing, and the vacuum degree in this kind of vacuum fresh-keeping cup is often not high

[0006] It can be seen that the existing vacuum cups generally have the problems of low vacuum degree and insignificant fresh-keeping effect
