Coffee container for beverage preparation and method of manufacturing a coffee container

Abstract

The invention relates to a method of manufacturing a coffee container ( 1 a - 1 g ) for preparing a coffee beverage upon injection of liquid into the container, the method comprising the steps of: —selecting and providing container wall means ( 2, 2 a, 3 a - 3 g ) for enclosing a predefined container, —compacting an amount of bulk coffee material such as roast and ground coffee particles to a coffee tablet under predefined compaction force in the container volume between the container wall means ( 2, 2 a, 3 a - 3 g ), —wherein the applied compaction force is set based on at least the provided container volume and/or on a particular type of beverage to be prepared from the provided container, and wherein the applied compaction force is set to a value between 0.5 to 15 kN, preferably between 1 kN and 10 kN.

1 . A method of manufacturing a coffee container for preparing a coffee beverage upon injection of liquid into the container, the method comprising the steps of:
 selecting and providing container wall member for enclosing a predefined container volume,   compacting an amount of bulk coffee material to a coffee tablet under predefined compaction force in the container volume between the container wall member,   wherein the applied compaction force is set based on at least the provided container volume and/or on a particular type of beverage to be prepared from the provided container, and   wherein the applied compaction force is set to a value between 0.5 to 15 kN.   
     
     
         2 . The method according to  claim 1 ,
 wherein the applied compaction force is set based also on the granulometry of the provided bulk coffee material and/or on the roasting value of the bulk coffee material.   
     
     
         3 . The method according to  claim 1 ,
 wherein a granulometry of the bulk coffee material lies between 150 to 600 μm and/or wherein the roasting value of the bulk coffee material lies between 50 and 120 CTN.   
     
     
         4 . The method according to  claim 1 ,
 wherein the applied compaction force is set lower for a small particle size and set higher for a larger particle size of the bulk coffee material.   
     
     
         5 . The method according to  claim 1 ,
 wherein the method comprises the step of sealingly connecting a first and second enclosing sheet constituting the container wall member about a circumference of the enclosed amount of coffee material under formation of a circumferential flange-like rim portion of the container.   
     
     
         6 . The method according to  claim 1 ,
 wherein the different selectable container wall member is designed for forming alternative types of containers.   
     
     
         7 . The method according to  claim 6 ,
 wherein the container type for preparing a short coffee beverage has a volume of between 5 ml and 15 ml.   
     
     
         8 . The method according to  claim 6 ,
 wherein the compaction force for a container type designed for preparing a short coffee beverage is set to a value between 0.5 kN and 5 kN, for a container type designed for preparing a long coffee beverage is set to a value between 0.5 kN and 15 kN, and for a container type designed for preparing a medium size coffee beverage is set to a value between 1 kN and 7 kN.   
     
     
         9 . A coffee container for preparing a coffee beverage upon injection of liquid into the container,
 the coffee container comprising container wall member enclosing a predefined volume of between 5 ml to 50 ml filled with compacted coffee material such as roast and ground coffee particles, and   wherein the coffee material is present in a form compacted under a compaction force of 0.5 to 15 kN.   
     
     
         10 . The coffee container according to  claim 9 ,
 wherein the height of the container is comprised between 5 mm and 30 mm.   
     
     
         11 . A kit of coffee containers comprising at least two containers for preparing a coffee beverage upon injection of liquid into the container, the method comprising the steps of: selecting and providing container wall member for enclosing a predefined container volume, compacting an amount of bulk coffee material to a coffee tablet under predefined compaction force in the container volume between the container wall member, wherein the applied compaction force is set based on at least the provided container volume and/or on a particular type of beverage to be prepared from the provided container, and wherein the applied compaction force is set to a value between 0.5 to 15 kN,
 wherein the respective containers differ in a volume enclosed by the container wall member and/or in a particular type of beverage to be prepared from the respective containers, and wherein the coffee material in the respective containers is present in a form compacted under a different compaction force.   
     
     
         12 . The kit according to  claim 11 ,
 wherein the respective containers differ in their height but comprise an equal outer diameter.   
     
     
         13 . The kit according to  claim 11 ,
 wherein the kit comprises a first container having a container volume of between 5 ml and 15 ml.   
     
     
         14 . The kit according to  claim 11 ,
 wherein the compaction force for the coffee material in the container designed for preparing a short coffee beverage lies between 0.5 kN and 10 kN.   
     
     
         15 . The kit according to  claim 11 ,
 wherein the different containers of the kit comprise coffee material of different granulometry.
