Metering container and metering device

A method for metering a food product, comprising the following steps;

• (a) providing a metering device for the food product, said metering device comprising a cylinder for accommodating a metering container for the food product and a plunger which is movably supported in the cylinder and adapted to compress the metering container accommodated in the cylinder, wherein the metering device comprises a motor connected to the plunger and adapted to move the plunger in the cylinder, and wherein an outside of the plunger of the metering device engages with an inside of the cylinder of the metering device in an airtight manner:
• (b) introducing the metering container for the food product into the cylinder of the metering device, wherein the metering container comprises a flexible wall having a wall thickness of 0.1 mm or less and a first end having a metering outlet and wherein the metering container contains the food product;
• (c) closing the region around the metering outlet by means of the metering device in an airtight manner;
• (d) moving the plunger of the metering device by means of the motor of the metering device such that the metering container is compressed so that the food product escapes from the metering outlet;
• and
• (e) retracting the plunger of the metering device by means of the motor of the metering device such that aara underpressure is generated in the region of the metering container in order to retract the food product through the metering outlet.
