Airless dispenser for e.g. dispensing cream in cosmetic field, has pedestal including edge to hermetically contact reservoir, and central part to receive spring, where spring is arranged outside pump and returns compression unit

摘要

#CMT# #/CMT# The dispenser has a pump (2) including an annular body (15) with a base (22), and a compression unit (16) movably mounted inside the body between high and low positions, where the body and the unit delimit a dosage chamber (17). A compression spring (50) is arranged outside the pump, and elastically returns the unit towards the high position. A pedestal (45) extends perpendicular to a central axis (23) and covers an opening of a reservoir (1). The pedestal has an outer peripheral edge hermetically contacting the reservoir, and a central part (46) receiving the spring. #CMT#USE : #/CMT# Airless dispenser for dispensing a viscous fluid product such as cream or gel, in pharmacy, cosmetic or perfumery field. #CMT#ADVANTAGE : #/CMT# The arrangement of the compression spring and the pedestal is such that the pump has reduced axial dimension and does not extend inside the reservoir. The pedestal can have a simple form so as to obtain an optimal inner volume available for the product, and an optimal distribution of the product. The arrangement of the compression spring simplifies the mounting and dismounting of the dispenser. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional representation of an airless dispenser. 1 : Reservoir 2 : Pump 15 : Annular body 16 : Compression unit 17 : Dosage chamber 22 : Base 23 : Central axis 45 : Pedestal 46 : Central part 50 : Compression spring.
