Abstract

A single-serve beverage receptacle includes a reservoir, arranged to contain a beverage or a beverage additive, and is provided with a bore, an outlet opening into the reservoir, at least one opening leading out of the reservoir, a bottom plug having a closed position the opening being sealed in a liquid-tight manner, and an open position where the opening is clear, a piston mounted in the bore, the piston being movable between first and second positions. The first position requires the bottom plug to be in the open position. The piston has a skirt and a disc rigidly connected to each other. The skirt having an outer surface in contact with the reservoir and an inner surface with an imprint arranged to be connected in a liquid-tight manner to an opening in a beverage container such that during the connection, the piston moves from the second to the first position.

Claims

1. A single-serve beverage receptacle (1) comprising:

a reservoir (2) adapted to contain a beverage or a beverage additive, the reservoir (2) being provided with a bore,

an outlet (6) opening onto the reservoir (2),

at least one opening (7) leading out of the reservoir (2) at a distance from the outlet (6),

a bottom cap (5) having a closed position wherein the opening (7) is sealed in a liquid-tight manner, and an open position wherein the opening (7) is clear,

a piston (3) mounted in the bore, the piston (3) being movable between a first position and a second position, the first position requiring the bottom cap (5) to be in the open position, the piston (3) comprising a skirt (31) and a disc (32) which are rigidly connected to each other, the skirt (31) being provided with an outer surface which is in contact with the reservoir (2) and an inner surface which is provided with an imprint adapted to be connected in a liquid-tight manner to an opening in a beverage container (100) in such a way that during connection, the piston (3) moves from the second position to the first position, and

an opening (38) to provide fluid communication between the inside (24) of the reservoir (2) and the opening (7), the opening (38) being open in the first position and closed in the second position of the piston (3).

2. The single-serve beverage receptacle as claimed in claim 1, wherein the opening (38) is radial and formed in the piston (3).

3. The single-serve beverage receptacle as claimed in claim 1, wherein the reservoir (2) is provided with a distal bore (25) of larger diameter and a proximal bore (26) of smaller diameter connected by a shoulder (27), the piston (3) being disposed in the bore (26) of smaller diameter, the disc (32) and the bore (26) of smaller diameter being in fluid-tight communication in the closed position, the disc (32) being moved away from the bore (26) of smaller diameter in the open position, the opening (38) facing the bore (25) of larger diameter.

4. The single-serve beverage receptacle as claimed in claim 1, wherein the interior surface of the skirt (31) is provided with at least two, preferably at least three, threaded stages.

5. The single-serve beverage receptacle as claimed in claim 1, wherein the imprint of the skirt (31) is a female thread and the piston (3) is helicoidally connected to the reservoir (2), the female thread and the helicoidal connection being in the same sense so that screwing the drink receptacle into the female thread can continue with the helicoidal movement of the piston (3) from the closed position to the open position.

6. The single-serve beverage receptacle as claimed in claim 1, wherein the opening (38) is in communication with the interior of the skirt (31).

7. The single-serve beverage receptacle as claimed in claim 1, wherein the opening (38) comprises a plurality of portions separated by studs (39) forming a junction between the disc (32) and the skirt (31).

8. The single-serve beverage receptacle as claimed in claim 1, wherein the reservoir (2) is cylindro-conical with a cylindrical portion of smaller diameter (21) near the outlet (6), a cylindrical portion (22) of larger diameter near the opening (7) and a frustoconical portion (23) disposed between the cylindrical portions of smaller diameter and of larger diameter, said portions being coaxial.

9. The single-serve beverage receptacle as claimed in claim 1, wherein the piston (3) is a monobloc piston and in the second position flush with the opening (7).
