Title: VACUUM JUICE FRESHNESS-PRESERVING 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.
