Abstract
A capsule for use in a coffee machine having a brew chamber, which capsule is formed from a ductile metal such as aluminium. The capsule has a generally frusto-conical form with an upper surface and a lower surface, an annular flange being provided at the lower surface. An annular seal is provided on the annular flange having first and second layers, wherein the first layer comprises long, well-bound fibres of a cellulose material that deforms plastically in use. The seal has an edge wick less than 5mm in an edge wick test with hot water at 95°C for 10 minutes. The seal of the invention provides a good seal, is more easily recycled than silicone seals and is resistant to delamination.
Claims (12)
1. A capsule for use in a coffee machine having a brew chamber, which capsule has a generally frusto-conical form with an upper surface and a lower surface, an annular flange being provided at the lower surface, wherein an annular seal is provided on the annular flange comprising a cellulose material such as paper that deforms plastically in use, n the annular seal comprises first and second layers, wherein the seal has an edge wick less than 5mm in an edge wick test with hot water at 95°C for 10 minutes.
2. A e ing to Claim 1, wherein the second layer comprises an elastically compressible material.
3. A capsule according to Claim 1 or Claim 2, wherein the seal further comprises an adhesive layer for ing the seal to the capsule rim.
4. A e according to any one of Claims 1 to 3, n the first layer is formed from chemical (sulphate) pulp or CTMP (chemi-thermomechanical pulp).
5. A capsule ing to Claim 3, wherein the seal comprises a layer of a liquid heat sealable adhesive.
6. A capsule according to any one of Claims 3 to 5, wherein the adhesive is starch based biodegradable adhesive having a melt range around 140 degrees Celsius.
7. A capsule according to any one of Claims 1 or Claim 2, wherein the seal is applied with pressure and heat without using an adhesive, wherein as pressure and/or the heat is applied the gasket swages out and tightens around the internal diameter of the seal to fix the seal in position on the capsule.
8. A e according to any one of Claims 1 to 7, wherein the seal is made from a non-coated board or only is only coated on one side and ink is applied to the non coated side.
9. A capsule according to any one of Claims 1 to 8, wherein a pattern is applied to a or the non coated side of the seal, which breaks up the print layer into small pieces, thereby allowing pressure to escape.
10. A capsule ing to Claim 8 or Claim 9, wherein the seal is laminated over the top of the printed e so that the ink is not in direct contact with the brew r of a coffee machine.
11. A capsule according to any one of Claims 1 to 10, wherein the seal has a tear resistance of 3000-5000 mN and an internal bond strength of greater than or equal to 90J/m2.
12. A capsule according to claim 1, substantially as herein described with reference to any one of the
