Container for ingredients for making beverages

Abstract

The invention relates to a container for ingredients for making beverages in the form of a rotation-symmetric truncated cone which is open at the larger bottom end of the truncated cone and closed at the smaller top end of the truncated cone by a top section of the truncated cone which preferably is of a flat, rounded, inclined or dented form or a combination of these forms, wherein the larger bottom end of the truncated cone can be closed by a base plate or membrane and can have an outward flange section to which the base plate or membrane can be attached, and wherein the thickness of the container wall is non-uniform, the container wall forming one or more circumferential stiffening rings which cover 10 to 50% of the container height, and wherein the wall thickness of the stiffening rings is at least 50% higher than the wall thickness in the remaining container wall outside the stiffening rings, the container having a maximum height of 5 cm and a maximum diameter without flange of 6 cm.

1 . A container for ingredients for making beverages in the form of a rotation-symmetric truncated cone which is open at a larger bottom end of the truncated cone and closed at a smaller top end of the truncated cone by a top section of the truncated cone,
 wherein the larger bottom end of the truncated cone can be closed by a base plate or membrane and can have an outward flange section to which the base plate or membrane can be attached,   and wherein a thickness of the container wall is non-uniform, the container wall forming one or more circumferential stiffening rings which cover 10 to 50% of the container height,   and wherein a wall thickness of the stiffening rings is at least 50% higher than the wall thickness in the remaining container wall outside the stiffening rings,   the container having a maximum height of 5 cm and a maximum diameter without flange of 6 cm,   wherein the truncated cone including the top section is prepared in one piece.   
     
     
         2 . The container according to  claim 1 , wherein the stiffening rings are located in a section extending from 10% to 90 of the container height. 
     
     
         3 . The container according to  claim 1 , having 1 to 5 stiffening rings. 
     
     
         4 . The container according to  claim 1 , wherein the wall thickness in the stiffening rings is at least two times the thickness outside the stiffening rings. 
     
     
         5 . The container according to  claim 1 , wherein the height of the container is in the range of from 2 to 3.5 cm and/or the cone diameter of the top section of the truncated cone is in the range of from 1.6 to 2.8 cm and/or the cone diameter at the bottom of the truncated cone, without flange, is in the range of from 1.8 to 3.2 cm. 
     
     
         6 . The container according to  claim 1 , wherein the stiffening rings cover 15 to 40%of the container height. 
     
     
         7 . The container according to  claim 1 , wherein the container wall thickness is in the range of from 0.1 to 1.0 mm. 
     
     
         8 . The container according to  claim 1 , wherein one the stiffening rings is located in the middle third of the container height. 
     
     
         9 . The container according to  claim 1  formed of a thermoplastic polymer. 
     
     
         10 . The container according to  claim 9 , wherein the thermoplastic polymer is selected from the group consisting of polyolefins, polystyrene, polyalkylene terephthalates, polyesters, polyethylene, polypropylene, polystyrene, polybutylene terephthalate, and biodegradable polyesters. 
     
     
         11 . A process for preparing a container as claimed in  claim 1  by injection-molding, a material forming the container. 
     
     
         12 . A capsule containing ingredients for making beverages in a container as claimed in  claim 1 , which is closed at the bottom end by a base plate or membrane. 
     
     
         13 . The capsule according to  claim 12 , wherein the base plate or membrane is formed of aluminum, a thermoplastic polymer, or a combination thereof. 
     
     
         14 . (canceled) 
     
     
         15 . A process for making beverages by inserting the capsule according to  claim 12  in a beverage-preparing apparatus in which water inlet and outlet holes are provided in the capsule and a water stream is directed through the capsule and recovered in a beverage recipient. 
     
     
         16 . The container according to  claim 1  wherein the top section of the truncated core is in a flat, rounded, inclined, or dented form, or a combination of these forms. 
     
     
         17 . The process according to  claim 1  wherein the water inlet and outlet holes are provided by puncturing the top section and the base plate, or membrane thereof.
