Abstract
Capsule for the preparation of a beverage in beverage preparation device comprising: a cup-shaped body (12) comprising a cavity containing a beverage ingredient and a flange-like rim extending outwardly from the base of said body, a delivery wall (13) connected to the flange-like rim, characterized in that the flange-like rim is formed of is a polymer material chosen in grade having a Vicat softening point (ISO 10350) between about 30 and 100° C., preferably between 40 and 90° C. or apolymer chosen in grade comprising a glass transition temperature (Tg) between 30 and 80° C., preferably between 40 and 60° C.
Claims15
Capsule for the preparation of a beverage in a beverage preparation device comprising:
- a cup-shaped body comprising a cavity containing a beverage ingredient and a flange-like rim extending outwardly from the base of the body,
- a delivery wall connected to the flange-like rim,
- the flange-like rim is formed of a polymer material having a characteristic selected from the group consisting of a Vicat softening point (ISO 10350) between about 30 and 100° C., and a glass transition temperature (Tg) between 30 and 80° C.
A system for the preparation of a beverage comprising:
- a capsule comprising a cup-shaped body comprising a cavity containing a beverage ingredient and a flange-like rim extending outwardly from the base of the body, a delivery wall connected to the flange-like rim, the flange-like rim is formed of a polymer material having a characteristic selected from the group consisting of a Vicat softening point (ISO 10350) between about 30 and 100° C., and a glass transition temperature (Tg) between 30 and 80° C.;
- and
- a beverage preparation unit, the unit comprises a capsule holder and an enclosing member for receiving the capsule, the enclosing member comprising an annular pressing surface comprising radial grooves, the pressing surface being designed to compress the flange-like rim of the capsule the material of the flange-like rim is designed during water injection for clogging the grooves of the pressing surface thereby providing a liquid-tight engagement between the capsule and the enclosing member.
