<p>MILK BAG PITCHER A covered pitcher for form-filled flexible plastic bags is provided. The flexible plastic bag is normally filled with a potable liquid such as milk, but fruit juices or wine may also be possible. The pitcher has a bottom portion of dimensions so as to substantially accommodate the flexible plastic bag when filled and sealed. The cover fits the bottom in co-operating manner. An opening is formed in the front upper corner of the cover, and the opening has a cutter head mounted therein for upward and downward movement within the opening. The cutter head is associated with a pair of curved and rockable arms which have closer faces that are curved away from each other at least in the upper portions thereof, and are mounted so as to be in close proximity to each other in the lower portions and over a substantial portion of the length of each closer face when the cutter head is moved to the lower end of the opening. A cutting edge is carried by the cutter head. When the bag is first placed in the pitcher, the cutter head is moved downwardly so as to cut off the front upper corner of the bag from which the potable liquid may then be dispensed; thereafter, when the cutter head is moved downwardly in the opening the bag is substantially sealed by the material of the bag immediately below the cut corner being captured between the closer faces.</p> |
