Description
- The invention is in the field of foodstuffs, and in particular that of single-serve beverage and beverage additive receptacles.
- Single-serve beverage receptacles can be filled with a first content to be poured into a principal receptacle itself containing a second content to obtain a mixture. For example, single-serve beverage receptacles in the form of fluid-tight sachets contain syrup intended to be poured into a bottle of water. In this case, the bottle of water must have a free volume sufficient to receive the content of the single-serve beverage receptacle without overflowing. Moreover, the user may through clumsiness pour the content of the single-serve beverage receptacle down the side of the principal receptacle. The use of such single-serve beverage receptacles is hardly practical.
- There also exist single-serve beverage receptacles specifically adapted to feed a machine. This is for example the case of single-serve beverage receptacles containing soluble coffee. The latter can be used only by means of a corresponding machine.
- The invention improves on this situation.
- The Applicant proposes a single-serve beverage receptacle comprising a reservoir adapted to contain a beverage or a beverage additive. The reservoir is provided with a bore. The single-serve beverage receptacle has an outlet opening onto the reservoir. The single-serve beverage receptacle includes at least one opening leading out of the reservoir at a distance from the outlet. The single-serve beverage receptacle includes a bottom cap having a closed position wherein the opening is sealed in a liquid-tight manner and an open position wherein the opening is clear. The single-serve beverage receptacle includes a piston mounted in said bore. The piston is movable between a first position and a second position. The first position requires the bottom cap to be in the open position. The piston comprised a skirt and a disc which are rigidly connected to each other. The skirt is provided with an outer surface which is in contact with the reservoir 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 in such a way that during connection, the piston moves from the second position to the first position. The single-serve beverage receptacle includes an opening to provide fluid communication between the inside of the reservoir and the opening, the opening being open in the first position and closed in the second position of the piston.
- A single-serve beverage receptacle of this kind enables mixing of the content of the single-serve beverage receptacle with that of a principal receptacle. The risks of soiling are reduced. The mixing operation can be carried out independently of the free volume available in the principal receptacle, the single-serve beverage receptacle forming an extension of the volume of the principal receptacle. Once installed on the principal receptacle, the outlet of the single-serve beverage receptacle is used by the user to drink the mixture. The user is able to reclose the combination of the principal receptacle and the single-serve beverage receptacle by closing the outlet of the single-serve beverage receptacle. The relative movement between the single-serve beverage receptacle and the principal receptacle imparted by the user to fix the single-serve beverage receptacle to the principal receptacle also serves to open the single-serve beverage receptacle to the principal receptacle.

FIG. 2 the components of the single-servebeverage receptacle 1 are ready to be assembled. Thepiston 3 can by axial movement in translation in theportion 26 of smaller diameter come to close the bottom of thechamber 24. Thebottom cap 5 can then be fixed to thereservoir 2. - In the state shown in
FIG. 1 , thetop cap 4 and thebottom cap 5 are at a distance from thereservoir 2. Thepiston 3 is in the closed position. Thebottom cap 5 can be fixed to thereservoir 2. Thechamber 24 of thereservoir 2 can be filled with liquid, for example syrup. Thetop cap 4 can then come to close thereservoir 2. - In the state shown in
FIG. 3 , thechamber 24 contains liquid. The seal between the piston and thereservoir 2 is operative. Thebottom cap 5 has been removed. The single-servebeverage receptacle 1 is ready to cooperate with thereceptacle 100. Thereceptacle 100 comprises a threadedneck 101 and a reservoir. Theintermediate stage 34 and thelower stage 35 have outside diameters one of which is matched to the outside diameter of the threadedneck 101. The threadedneck 101 can therefore be screwed into thepiston 3. - In the state shown in
FIG. 4 the threadedneck 101 has been screwed into thepiston 3. The threadedneck 101 forms a seal with thepiston 3. The screwing movement of the threadedneck 101 has enabled thepiston 3 to be driven toward theoutlet 6, i.e. has enabled movement of thepiston 3 from the closed position to the open position. Theholes 38 open into thechamber 24. The liquid flows downward in the direction of the arrow. - The exterior surface of the
piston 3 and theportion 26 of smaller diameter are preferably threaded in a complementary manner. The thread is in the same sense as the thread of the threadedstages stages piston 3 into thereservoir 2 to open communication between thechamber 24 and the interior of thepiston 3. The thread may have the same pitch as the thread of the threadedstages piston 3. - Thus when the screwing torque of the threaded
neck 101 increases at the end of screwing onto said threadedneck 101 said screwing torque exerted by the user becomes sufficient to drive thepiston 3 in helicoidal rotation because of the thread whereby thepiston 3 and thereservoir 2 cooperate. - The invention is not limited to the examples of single-serve beverage receptacles described hereinabove by way of example only and encompasses all variants that the person skilled in the art might envisage within the scope of the following claims
