Abstract
Devices for being fitted to a beverage making machine extraction head have a ring member which has a wall which extends to define a hollowed interior portion suitable for being fitted about a periphery of a coffee machine water injection system extraction head which surrounds a water injection passage. The hollowed interior is defined further by a base connected to and disposed transversely with respect to the wall. The base may be a ring wall portion which provides a grill and which has projections extending therefrom, or may be a ring wall portion which has a hole therethrough and which has projections extending therefrom, or may be a ring wall portion which has a centrally disposed needle portion which contains at least one opening so that upon the ring member being fitted about the extraction head, the base is positioned adjacent a base of the extraction head, and so that the projections or needle are positioned to extend away from the extraction head base. The devices also include a cartridge holder, which may be an element integral with the ring member or separate therefrom, and a cartridge holder support.
