1. 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. 2. Capsule according to claim 1, wherein the polymer material is selected from the group consisting of: polyethylene,a blend of: a polymer selected from the group consisting of polyethylene (PE) and polypropylene (PP); and at least one polymer selected from the group consisting of: ethylene copolymer(s) and terpolymer(s) and combinations thereof. 3. Capsule according to claim 2, wherein the copolymer(s) is selected from the group consisting of: EVA (Ethylene vinyl acetate), EMA (ethylene glycol monobutyl monomer ether acetate), EBA (poly(ethylene-co-butyl acrylate) and combinations thereof, ora rubber elastomer or plastomer, preferably EPDM (ethylene propylene diene monomer)and combinations thereof. 4. Capsule according to claim 1, wherein the polymer material is an agro-resource based polyester. 5. Capsule according to claim 1, wherein the polymer material is selected from the group consisting of: crystallized or semi-crystallized PET (cPET), crystallized or semicrystallized polylactic acid (cPLA) PET (polyethylene terephtalate), PLA (polylactic acid) and combinations thereof 6. Capsule according to claim 1, wherein the delivery wall is a membrane designed to be at least partially torn under pressure against protrusions provided on the capsule holder during water injection. 7. Capsule according to claim 1, wherein the delivery wall has filtering apertures. 8. Capsule according to claim 7, wherein the filtering apertures have a diameter of less than 300 microns. 9. Capsule according to claim 1, wherein the flange-like rim has a thickness which comprises at least a portion which is of greater thickness than a thickness of at least one of the other walls of the body. 10. Capsule according to claim 1, wherein the flange-like rim comprises at least one lip forming a local increase of thickness protruding from the rim in a direction opposite to the membrane. 11. Capsule according to claim 1, wherein the membrane is an aluminium or aluminium alloy membrane. 12. Capsule according to claim 1, wherein the membrane is made of the same material as the polymer material of the body. 13. Capsule according to claim 1, wherein the rim has a thickness of between 0.5 and 1.2 mm. 14. 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.; anda 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. 15. Method for the preparation of a beverage, using the capsule of claim 1 containing a dose of beverage ingredient, by insertion of a capsule in a beverage preparation unit comprising a capsule holder and a water injection enclosing member; comprising the steps of: inserting the capsule between the capsule holder and the water injection enclosing member while pressing the sealing rim against the capsule holder by a grooved pressing surface of the water injection enclosing member;injecting water under pressure in a volume between the capsule and water injection enclosing member and in the capsule;providing a bypass of water at the beginning of the water injection operation between a pressing surface comprising radial grooves and the capsule, the water bypass is stopped or reduced as further water is injected;forcing a liquid extract to flow from the interior of the capsule through the delivery wall, apertures of the capsule holder and to a discharge duct; andthe water bypass is collected and discharged through the discharge duct.
