Apparatus for extracting substances contained in sealed pliant bags
First Claim
1. Apparatus for holding a bag containing a substance for preparation of a beverage for extraction of the substance comprising:
- a housing member which comprises first and second portions wherein the housing member second portion extends from the housing member first portion and has a wall surface which defines a cavity for containing a bag, wherein the bag has a linear edge weld portion and contains a substance for preparation of a beverage, wherein the housing member second portion is configured for containing the bag so that when the bag is contained by the housing member second portion, the linear edge weld portion is positioned adjacent the housing member first portion and wherein the housing member first portion contains a bore which passes therethrough so that the bore communicates with the cavity;
means positioned for, upon containment of a bag by the housing member second portion, securing the linear edge weld portion against the housing member first portion;
raised members which extend from the housing member second portion wall surface into the cavity at a position adjacent the housing member first portion for defining a grid area of raised and indented portions for tearing a bag contained by the housing member second portion and flow holes positioned in the grid area which pass through the housing member second portion for, upon tearing of a bag by the raised members, passing extract from the cavity through the housing member; and
a handle which extends from the housing member second portion.

Abstract
A bag-holder and an extraction machine for enabling extraction of a substance for preparation of a beverage contained in a pliant bag having at least one linear edge weld. The bag-holder has a housing configured to provide a cavity for containing the bag and an area which provides a grid of raised and indented elements and flow holes, the grid area providing for tearing the bag and for flow of extract from the housing during extraction. The bag-holder also has provision for securing the edge weld of the bag to keep the bag in the holder. The bag-holder also contains a bore in the area of the outflow grid for accepting a hollowed needle therethrough for penetrating into a bag for introducing extraction fluid into the bag and wherein the needle, during extraction, extends from an extraction machine which also has a part for, upon placement of the bag-holder together with the extraction machine, enabling sealing the part and the holder.
