Abstract
An improved modular lotion pump for dispensing personal products such as lotions, creams, etc., and a method of assembling same is disclosed. The modular pump is formed of several subassemblies that are subsequently assembled to form the modular pump assembly. A cap having means for attachment to a container from which material is to be dispensed may be snap fit onto the modular pump. The pump includes a rotatable locking sleeve for preventing leakage even if the container is squeezed or stepped upon by a consumer and for changing the orientation of the actuator. The actuator may be rotated relative to the locking sleeve to prevent accidental dispensing.
