Abstract: Embodiments described herein relate to a liquid extraction device for extracting liquid from a liquid storage container, the liquid extraction device comprising: a receptacle configured to receive a portion of the liquid storage container; a liquid storage container interface housed within the receptacle, wherein the liquid storage container interface is configured to provide a fluidic connection to a volume of liquid within the liquid storage container when the liquid storage container is connected to the liquid storage container interface; and a safety mechanism actuatable from a first safety mechanism configuration to a second safety mechanism configuration, wherein the safety mechanism is configured to conceal the liquid storage container interface when the safety mechanism is in the first safety mechanism configuration, and wherein the safety mechanism is configured to reveal the liquid storage container interface when the safety mechanism in the second safety mechanism configuration.

Abstract: The present invention provides a method, a system and a computer program product for communication across a network of computational devices. The present invention makes use of a virtual environment module for communication. The virtual environment module is utilized by a first user to communicate with one or more groups of contacts, who are connected to the first user via the networks of data-processing units. The first user utilizes various functions present in the virtual environment module, to send information to or receive information from the one or more groups of contacts. Further, the first user can also select the one or more groups of contacts with whom he/she wishes to communicate.
