Description

TECHNICAL FIELD

[0001] The utility model relates to the field of packing bottle, especially a press pump with sealing nozzle structure and packing bottle. BACKGROUND

[0002] The Chinese patent with publication number CN220077212U discloses a press pump with a closable output port, comprising a main housing, a pressing piece, a pump body assembly, and an output assembly. The pressing piece is movably arranged in the main housing, and the pump body assembly is arranged in the main housing and can be driven by the pressing piece. The output assembly includes a discharge nozzle and a blocking piece. The discharge nozzle is arranged in the main housing and is provided with an output channel connected to the pump body assembly. The blocking piece is movably arranged at the outlet of the output channel. A linkage structure is arranged between the blocking piece and the pressing piece. When the pressing piece is not pressed, the pressing piece can limit the blocking piece to be inserted into the output channel through the linkage structure. When the pressing piece is pressed, the pressing piece can drive the blocking piece to a position away from the output channel through the linkage structure. When the press pump is not in use, the emulsion in the pump body assembly is isolated from the outside, reducing the possibility of contamination of the emulsion in the pump body assembly.
