Abstract
The present invention provides a reinforcement ring (10) for capsules for obtaining beverages, for example espresso coffee, comprising a side wall (1) and a flat surface, preferably having a uniform thickness (2), protruding from the side wall (1), wherein the side wall (1) and the protruding flat surface (2) are made in a single body and wherein the side wall (1) comprises reduced thickness areas (3), so as to reduce the total amount of material used for the production of the ring. A capsule for obtaining beverages comprising such a reinforcement ring (10) is also provided.
Claims23
A capsule for making infusion beverages, the capsule which comprises:
- a permeable material capsule body suitable to form a containment volume for a product used to make the infusion beverage;
- and
- a reinforcement ring reinforcing the permeable material capsule body, the reinforcement ring comprising:
- a side wall having a circumference configured to fit within a device for obtaining infusion beverages, said side wall having an outer wall surface and an inner wall surface;
- a flat surface configured to be held in the device for obtaining infusion beverages, wherein the flat surface protrudes from said side wall, said side wall and said flat surface forming an integral single body, wherein formed in said side wall are side wall depressions spaced in a circumferential direction along the circumference with separating side wall portions separating the side wall depressions,
- wherein reduced thickness areas of said side wall provided by said side wall depressions have a radial thickness that decreases going away from the flat surface, and
- wherein the inner wall surface is fixed to the permeable material capsule body.
A beverage capsule reinforcement ring reinforcing a liquid permeable material capsule body of a beverage capsule, the reinforcement ring comprising:
- a side wall having a circumference configured to fit within a device for obtaining beverages and an outer wall surface and an inner wall surface, said sidewall having a first side wall material radial thickness extending from the outer wall surface to the inner wall surface;
- reduced thickness areas formed periodically around the circumference along a circumferential direction in said side wall indented inwardly from the outer wall surface, said reduced thickness areas having a second side wall material radial thickness extending from the reduced thickness areas to the inner wall surface, wherein the second side wall material radial thickness is less than the first side wall material radial thickness;
- a flat surface extending radially from an edge of said side wall configured to be held in the device for obtaining beverages;
- wherein said reduced thickness areas formed in said side wall have a radial thickness that decreases going away from said flat surface;
- and
- ring grooves formed in the inner wall surface, wherein the inner wall surface is fixed to the liquid permeable material capsule body.
A permeable beverage capsule used in making infusion beverages, the permeable beverage capsule comprising:
- a liquid permeable material forming a capsule body configured to fit within a device for obtaining infusion beverages;
- a reinforcement ring encircling and attached to an edge portion of said liquid permeable material forming a capsule body, said reinforcement ring configured to be held in the device for obtaining infusion beverages, said reinforcement ring comprising:
- a flat surface forming a ring having an inner edge;
- a cylindrical side wall extending from the inner edge of said flat surface and having an outer and inner wall surface, said cylindrical side wall having a first side wall material radial thickness;
- and
- reduced thickness areas indented inwardly from the outer wall surface and having a second side wall material radial thickness formed in the outer wall surface periodically around a circumference along a circumferential direction of said cylindrical side wall, wherein the second side wall material radial thickness is less than the first side wall material radial thickness.
A permeable beverage capsule used in making infusion beverages, the permeable beverage capsule comprising:
- a liquid permeable material forming a capsule body configured to fit within a device for obtaining infusion beverages;
- a reinforcement ring encircling and attached to an edge portion of said liquid permeable material forming a capsule body, said reinforcement ring configured to be held in the device for obtaining infusion beverages, said reinforcement ring comprising:
- a flat surface forming a ring having an inner edge;
- a side wall ring extending from the inner edge of said flat surface and having an outer side wall surface and an inner side wall surface, said side wall ring having a first side wall material radial thickness;
- and
- reduced thickness areas indented inwardly from a surface of said side wall ring, said reduced thickness areas formed in the surface periodically around a circumference of said side wall ring along a circumferential direction, each of said reduced thickness areas having a second side wall material radial thickness, wherein the second side wall material radial thickness is less than the first side wall material radial thickness.
