Claims15
A beverage preparation capsule comprising:
- a body formed substantially from a filtration sheet material, a liquid injection nozzle for injecting liquid into the body, and a beverage preparation ingredient retained inside the capsule body.
A capsule according to any preceding claim, wherein two opposed edges of said filtration sheet material are bonded together to form a sealed edge of said body, and said nozzle is secured in said sealed edge by bonding of the nozzle to the said two opposed edges of the filtration sheet material.
A beverage preparation capsule according to any preceding claim, wherein the body consists essentially of superimposed front and back sheets of the filtration sheet material that are bonded together around their peripheries.
A beverage preparation capsule according to any preceding claim, wherein the nozzle is a thermoplastic nozzle having a tubular bore for receiving a liquid injector tube from a beverage preparation machine.
A beverage preparation capsule according to any preceding claim, further comprising a screen of a liquid-impermeable sheet material partially enclosing the capsule body, wherein the screen comprises an opening in a lower region thereof to allow escape of beverage from the capsule.
A packaged beverage preparation capsule comprising a beverage preparation capsule according to any preceding claim, and secondary packaging enclosing the capsule, wherein the secondary packaging is substantially impermeable to oxygen and moisture.
A method of manufacture of a beverage preparation capsule comprising the steps of:
- providing a first web of filtration sheet material;
- depositing a dose of a beverage making ingredient at a location on the said first web;
- depositing a liquid injection nozzle on the first web adjacent to the location of the dose of beverage making ingredient
- superimposing a second web of filtration sheet material on the first web, the dose of beverage making ingredient and the nozzle;
- bonding the first and second webs together along a sealing margin extending around the location of the dose of beverage-making ingredient and including the location of the nozzle, such that the nozzle is sealed between the first and second webs in said margin by said bonding;
- and
- cutting the first and second webs around said sealing margin to release said capsule from the webs.
