A spout is mounted on the spout mounting portion and is resiliently deformable, having an open spout end opposite a connecting portion which is connected to the spout mounting portion. The open spout end is in communication with the interior of the main body portion. A piston is slidably received within the sidewall of the main body portion, and is substantially hollow and includes a lower piston body portion and a lid portion, the lower piston body portion having a lower piston face and an upstanding piston sidewall. The upstanding piston sidewall has adjacent an uppermost end thereof a detachable attaching arrangement for removably attaching the lid portion to the lower piston body portion. A handle extends from the piston lid, and a pot lid closes the pot main body portion so as to enclose the piston between the bottom pot wall and the pot lid, the pot lid having an opening therein slidably receiving the handle. The piston lid has an opening therethrough in communication with the interior of the piston, and the piston sidewall has a plurality of grooves which extend along the entire length of the piston lower portion sidewall. At least one groove extends completely across the lower piston face.
