Abstract
The present disclosure provides an aerosol unit for an aerosol dispenser. The aerosol unit includes an axially oriented body, having a distal inlet part and a proximal outlet part. The aerosol unit also includes a carrier member arranged in the body, transversally to the axis between the inlet part and the outlet part. The carrier member includes through-holes which place the inlet part in fluid communication with the outlet part, and the carrier member is insert-moulded into the body such that a contact surface between the carrier and the body forms an air-tight seal.

An aerosol unit for an aerosol dispenser, the aerosol unit comprising:
- an axially oriented body, having a distal inlet part and a proximal outlet part;
- and
- a carrier member arranged in the body, transversally to the axis between the inlet part and the outlet part,
- wherein the carrier member comprises through-holes which place the inlet part in fluid communication with the outlet part,
- wherein the carrier member is insert-moulded into the body such that a contact surface between the carrier and the body forms an air-tight seal, and
- wherein the outlet part comprises an outer fluid flow channel and an inner fluid flow channel, wherein the outer fluid flow channel and the inner fluid flow channel are coaxially arranged, and wherein a turbulence structure extends proximally a distance from the carrier member, between the inner fluid flow channel and the outer fluid flow channel.
An aerosol unit for an aerosol dispenser, where the aerosol unit comprises:
- an axially oriented body having a distal inlet part and a proximal outlet part aligned along a longitudinal axis;
- a metal carrier member separating the distal inlet part from the proximal outlet part and comprising through-holes, where the carrier member is insert-moulded into the body transversally to the longitudinal axis to form an air-tight seal between the distal inlet part and the proximal outlet part;
- and
- a micro nozzle associated with the carrier member configured to allow a pressurised fluid product to be sprayed,
- wherein through-holes provide fluid communication between the distal inlet part and the proximal outlet part, and
- wherein the proximal outlet part comprises an outer fluid flow channel and an inner fluid flow channel, where the outer fluid flow channel and the inner fluid flow channel are coaxially arranged.
