A feeding apparatus comprising: a separate food container (7) comprising an open end (71), a closed end (72), an annular flange (73) at the open end (71), and a plurality of openings (8) contiguous at least to the closed end； a first coupling member (5) comprising an opening (51) in communication with the open end (71) of the container, food container (7) being able to be coupled with the first coupling member (5)； and a second coupling member (3) that is separated from the food container (7), and that can cooperate with the first coupling member (5) to be movable between an open configuration that allows the food to pass through the opening (51) of the first coupling member (5) and into the food container (7), and a sealed configuration in which the second coupling member covers and closes the opening (51) of the first coupling member (5) ), thus sealing the open end (71) of the food container (7)； in which the food container (7) is made of a soft elastic material and is deformable between an original shape that has a first volume and a deformed shape that has a second volume, whereby the food necessarily passes through the openings (8) when the food container (7) is deformed by an external force and when the external force is removed, the food container (7) returns to its original form； characterized by a position fixing mechanism having a notch (75) on one of the edges of the annular flange (73) of the food container (7) and the first coupling member (5), and a projection (58) on the other edge of the annular food container flange (7) and the first coupling member (5), the notch (75) and the projection (58) fixing a position of the food container (7) separated when the annular flange (73) is held between the annular platform (54) of the first coupling member (5) and the second coupling memberUn aparato de alimentación que comprende: un recipiente de alimento separado (7) que comprende un extremo abierto (71), un extremo cerrado (72), un reborde anular (73) en el
