Abstract

A cartridge for use with a mounting head for the preparation of fluid comestibles comprising a cartridge inlet, a chamber connected to said cartridge inlet for containing suitable flavor-containing or particle materials, a cartridge outlet connected to said chamber and a handle enabling a user to hold the handle to attach and secure the cartridge inlet to the mounting head to allow the liquid to be delivered under pressure through the flavor-containing or particle materials in the chamber, through the cartridge outlet and directly into a receptacle such as a cup or carafe for consumption, thereby dramatically simplifying the preparation of the fluid comestibles and relieving the user from the tedious cleaning work. The handle comprising at least part of the wall of the chamber, which is sufficiently rigid.
