1. Nozzle: bayonet (half bayonet aluminum, full bayonet aluminum), screw mouths are plastic, but some have a layer of aluminum cover on top, anodized aluminum.

2. Lotion pump: the vacuum and suction tubes are screwed. The large cover of the screw mouth and the head cap can also be covered with an aluminum cover of anodized aluminum. Divided into sharp-billed and duck-billed.

3, hand washing pump: the diameter is too large, all are screw. The large cover of the screw mouth and the head cap can also be covered with an aluminum cover of anodized aluminum. Generally there are steps that are threaded, and those without steps are left and right knobs.

Length measurement: Length of the pipette (length from gasket to end of hose or FBOG). Exposed length. And the length measured under the cap (equal to the length from the shoulder to the bottom of the bottle).

Specification classification: It mainly depends on the product inner diameter (inner diameter is the innermost diameter in the pump) or large circle height classification.

Nozzle: 15/18/20 MM full plastic is also divided into 18/20/24

Lotion Pump: 18/20/24 MM

Hand washing pump: 24/28/32 (33) MM

Height of big circle: 400/410/415 (only pure specification code is not actual height)

Note: The expression of specification classification is as follows: lotion pump: 24/415

Metrological measurement methods: (actually the liquid dose of the spray head once) There are two methods of peeling measurement and absolute value measurement. The error is within 0.02g. The pump body size is also used to distinguish the measurement.
