ABSTRACT:
A dispensing container for storing and dispensing pre-packaged quarter pound segments of softened butter or similar dispensible materials. Segments of butter pre-packaged in plastic envelopes are constrained between a movable butter feed plate and a stationary base in conjunction with a sealing plate within the container for dispensing butter therefrom. The sealing plate includes a hinged sealing edge that cooperates with a rigid feed lip at the front of the container to define a feed passageway and to seal an end of the envelope that is disposed therebetween. Depressing the feed plate compresses the pre-softened butter within the packaging envelope to open the feed passageway and force butter through the envelope end. When the feed plate is released, the feed passageway is automatically sealed.
