The present invention relates generally to a capsule for use in the preparation of a beverage; for example a capsule for use in the preparation of tea or coffee contained in the capsule using hot water injected under pressure.
The present invention seeks to provide improvements in or relating to beverage capsules.
In some aspects the present invention provides or relates to a perforable beverage capsule comprising a generally frustoconical body having a sidewall closed at one end by bottom wall.
In some aspects the present invention provides or relates to a perforable beverage capsule comprising a generally frustoconical body having a sidewall closed at one end by a piercable inlet wall through which hot water can be injected in use.
The capsule may comprise a rim. A closure, such as a foil seal, may be applied over the rim e.g. to hermetically seal the contents of the capsule. The rim may comprise or include some means of improving sealing e.g. for sealing the closure and/or for sealing against components of a beverage making machine into which the capsule is inserted in use.
The piercable inlet wall or bottom wall may include a central “star like” structure to provide rigidity. Alternatively or additionally the perimeter of the bottom wall may be formed as a star or star-like structure.
The bottom wall and sidewall may be joined by a wall section which is formed by a plurality of facets or facet-like structures.
In one embodiment the bottom design includes a star structure for bottom rigidity.
A central, recess star-like structure may be provided. Alternatively or additionally the perimeter of the bottom wall may be formed as or include a star-like structure. A plurality of circumferentially distributed triangular (for example isosceles) shapes may form the star-like structures.
An aspect of the present invention provides a beverage capsule with a sealing ring formed from a foamed material.
In one aspect the present invention provides a perforable beverage capsule comprising a generally frustoconical body having a sidewall closed at one end by a piercable inlet wall through which hot water can be injected in use, the end of the sidewall opposite the inlet wall having a rim, and a sealing ring is provided.
A foil member or other form of closure may, for example, be sealed to the flange-like rim to close-off hermetically a cup-like body of the capsule.
The ring may provide an improved seal in use in a beverage making machine (such as a coffee pod machine) and/or during sealing of a closure across the rim.
The ring may be formed as a separate part which is joined or otherwise secured to the rest of the capsule.
The ring could be produced in various processes. E.g.:
The sealing ring can be attached to each kind of capsule made out of each type of material.
The ring may be fitted against (for example “under” the rim). In some embodiments the rim is provided with a channel, gully, undercut or the like to receive the ring.
The ring may be a flat, disc-like annulus.
The rim end of the body may be sealed, for example with a foil liner or the like.
A further aspect provides a perforable beverage capsule comprising a generally frustoconical body having a sidewall closed at one end by a piercable inlet wall through which hot water can be injected in use, at least part of the body wall having a multi-faceted surface.
The faceting can be used to provide increased strength of the body and additionally can provided aesthetic benefits.
In some embodiments the sidewall comprises a plurality of generally triangular, contiguous facets.
Between the sidewall and the inlet wall an intermediate wall section may be provided. The intermediate wall section may be faceted.
The intermediate wall section may be inclined radially inwardly with respect to the sidewall.
