Apparatus for extracting a substance contained in a sachet
First Claim
1. An apparatus for extracting, with water under pressure, a comestible substance contained in a sachet package comprising:
- a first member and a second member whereinthe first member comprises a base, a wall surface and a wall rim wherein the wall surface extends laterally from the base to the rim to define a first member cavity and wherein the base contains holes therethrough for flow of an extract from the cavity through the base and comprises a surface and raised portions wherein the raised portions extend from the base surface into the first member cavity for tearing a sachet sheet positioned adjacent and deformed under pressure against the raised portions;
the second member comprises a wall surface and an edge wherein the wall surface defines a second member cavity and extends to the edge; and
the first member and second member are configured so that upon bringing the first member rim and the second member edge together, the first and second member cavities form a chamber confined by the wall surfaces and base and each of the cavities define substantially one-half of the chamber for containing sheets of a sachet which extend to a sachet edge and contain a comestible substance for preparation of a beverage and so that the first member rim and the second member edge are configured to grip the sachet edge and to provide fluid-tightness and so that upon bringing the rim and edge together to grip the sachet edge and to provide fluid-tightness, the rim and edge stretch the sachet;
a chassis and chassis mounting affixed with the first member and second member so that the first and second members are mounted to the chassis about an axis so that movement of one member relative to the other is through a plane transverse to the axis and so that upon movement about the axis one member to the other, the first member rim and the second member edge are brought together to form the chamber, grip the sachet edge, provide fluid-tightness and stretch the sachet;
means which extend from the second member into the second member cavity for, upon the bringing of the first member rim and second member edge together, perforating a sheet of a sachet which contains a comestible substance for preparation of a beverage to obtain a perforated sachet and for introducing water for extracting the substance contained in the perforated sachet; and
fastening means integral with each of the first and second members and comprising a lever which extends from one of the first and second members to the other member for, upon the first and second members being together, rigidly fastening the first and second members together to form the chamber, grip the sachet edge, provide fluid-tightness and stretch the sachet.

Abstract
An apparatus for extracting a substance contained in a sachet for preparation of a beverage has a first member having raised and hollow portions for forming a flow zone and a second member for cooperating with the first member to form a chamber to contain the sachet for extraction of the substance and to grip the edge of the sachet to ensure fluid-tightness upon being tightened, each member being configured for forming substantially half of the chamber for containing and ensuring a specific sachet shape. In one embodiment, the second member has provision for perforating an upper surface of a sachet for introducing water into the sachet. In another embodiment, the first member has an injector member which projects beyond the raised portions for perforating and introducing water into the sachet. The first and second members may be mounted on a chassis so that the members are mounted about an axis so that upon movement about the axis, the members are brought together so that they form the chamber, and a rim of the first member and an edge of the second member cooperate for gripping an edge of a sachet.

1. An apparatus for extracting, with water under pressure, a comestible substance contained in a sachet package comprising:
-
a first member and a second member wherein the first member comprises a base, a wall surface and a wall rim wherein the wall surface extends laterally from the base to the rim to define a first member cavity and wherein the base contains holes therethrough for flow of an extract from the cavity through the base and comprises a surface and raised portions wherein the raised portions extend from the base surface into the first member cavity for tearing a sachet sheet positioned adjacent and deformed under pressure against the raised portions; the second member comprises a wall surface and an edge wherein the wall surface defines a second member cavity and extends to the edge; and the first member and second member are configured so that upon bringing the first member rim and the second member edge together, the first and second member cavities form a chamber confined by the wall surfaces and base and each of the cavities define substantially one-half of the chamber for containing sheets of a sachet which extend to a sachet edge and contain a comestible substance for preparation of a beverage and so that the first member rim and the second member edge are configured to grip the sachet edge and to provide fluid-tightness and so that upon bringing the rim and edge together to grip the sachet edge and to provide fluid-tightness, the rim and edge stretch the sachet; a chassis and chassis mounting affixed with the first member and second member so that the first and second members are mounted to the chassis about an axis so that movement of one member relative to the other is through a plane transverse to the axis and so that upon movement about the axis one member to the other, the first member rim and the second member edge are brought together to form the chamber, grip the sachet edge, provide fluid-tightness and stretch the sachet; means which extend from the second member into the second member cavity for, upon the bringing of the first member rim and second member edge together, perforating a sheet of a sachet which contains a comestible substance for preparation of a beverage to obtain a perforated sachet and for introducing water for extracting the substance contained in the perforated sachet; and fastening means integral with each of the first and second members and comprising a lever which extends from one of the first and second members to the other member for, upon the first and second members being together, rigidly fastening the first and second members together to form the chamber, grip the sachet edge, provide fluid-tightness and stretch the sachet. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. An apparatus for extracting, with water under pressure, a comestible substance and comprising:
-
a first member comprising a base, a wall surface and a wall rim wherein the wall surface extends laterally from the base to the rim to define a first member cavity and comprising a water injector delivery member which extends laterally from the base and into the cavity and terminates in an end suitable for piercing a sheet of material of a package containing a substance for preparation of a beverage and for delivering water under pressure within the package and wherein the base contains holes therethrough for flow of an extract from the cavity through the base and comprises a surface and raised portions wherein the raised portions extend from the base surface into the cavity to a position at a distance from the base surface which is less than a distance of the injector member end from the base surface for, upon introducing water via the injector member under pressure into an injector member pierced package and placing the sheet under pressure so that the sheet deforms, contacting the sheet so that the sheet under pressure deforms against the raised portions for tearing the sheet; a second member having a wall surface which defines a second member cavity and which extends to an edge suitable for cooperating with the first member rim to grip a package edge and provide fluid-tightness; and means for rigidly fastening the first and second members together to grip the package edge and provide fluid-tightness.
