Abstract: The storage bag includes an interior volume for containing food items and a one-way valve element through which air from the interior volume can be evacuated. To prevent fluids and juices from the stored food items from contaminating the valve element, a separator defining a chamber is included that sealingly connects the valve element to the interior volume. In the separator, fluids and juices separate from the evacuating air by gravitational separation and are returned to the interior volume. In an embodiment, to facilitate packaging and distribution of multiple storage bags, the separator is adjustable between an expanded position for providing the chamber and a collapsed position substantially eliminating the chamber. In an embodiment, the separator may be comprised of elastically expandable material.

Abstract: A beverage dispenser for ejecting a beverage into a receptacle, including a housing including a taking-in/out space, nozzles provided in the beverage dispenser for ejecting the beverage, obstacle detection module for detecting an obstacle around the nozzle, alarm generator for issuing an alarm when the detection module detects the obstacle, and a nozzle cover for covering the plurality of nozzles and the obstacle detection module to partially close the taking-in/out space. The alarm may not be issued from the alarm means when the beverage is ejected or a switch may be provided for causing the alarm generator inoperative. Thereby, those around the dispenser are informed of the fact that an operator has had unauthorized access to the nozzle in the beverage dispenser.
