The airless
Cartridge + Cap

​are the core components of a Soft Mist Inhaler (SMI) and serve as a container for filling the pharmaceutical product.

Our patented airless bag-in-bottle system, which has proven itself in the medical and pharmaceutical industries, can be customised to the requirements of the various SMI devices.

It offers the best possible product protection for medications such as generics, biologics and active pharmaceutical ingredients.

How it works

The airless cartridge + cap contains the pharmaceutical product and is placed in the SMI inhalation device.
The outer bottle of the multi-layer cartridge remains rigid.
The flexible inner bag contracts in a controlled manner, reducing the inner volume without allowing air or contaminants to enter the system (Airless Motion® bag-in-bottle system).
The medication is applied through the inhalation system.
The airless cartridge (bag-in-bottle system) allows medication/formulation to remain unaffected as it eliminates the need for any propellant.
The cartridge solution enables multiple use / refill of the inhalation system

Benefits

The combination of device and bag-in-bottle system ensures a fine spray mist without propellant
The dosage volume from the cartridge can be customized
The special barrier properties of the flexible inner bag protects the formulation from chemical, physical, and microbiological contamination​
The controlled collapsing of the inner bag enables a high restitution rate​
The 360° application is a key advantage in emergency situations
