Dual chamber lotion pump |
摘要 |
A manually operated vertically reciprocated pump dispenser has a simplified construction with two separate pumps that pump two separate liquids from a container and keep the two separate liquids separated from each other as they are pumped through the dispenser, mixing the liquids for the first time in a discharge passage of the dispenser just prior to the mixed liquids being discharged from the dispenser. The dispenser has a rotatable sleeve that covers the two pumps and is rotated to lock and unlock a dispenser head that operates the two pumps.
