Abstract: The invention pertains to a coupling for a liquid product packaging and dispensing assembly in which liquid is pumped from a container via the coupling through a tube to the point of use. The coupling has a first interconnectable member with a hollow post and a biased sleeve closing openings in the hollow post and a second interconnectable member with a hollow sheath and a biased piston closing an opening at the end of the sheath. The parts are configured so that, upon connection, the post unseats the piston while the sheath displaces the sleeve, thereby allowing liquid flow. An elastic ring is present between the sheath and the sleeve which ring is compressed in the axial direction and expanded in the radial direction toward the post so as to establish a close fit around the post.

The piston and the post are configured such that, upon connection, any fluid residing between them is displaced.

Abstract: A container (1) for storing and dispensing fluid material, in particular liquid detergents or the like, comprises a flexible collapsible storage portion (4) for storing the fluid material, and a dispensing portion (5) in communication with the storage portion in order to dispense the fluid material from the storage portion in a controlled manner. The storage portion has a substantially rectangular rounded shape. One side (7) thereof contains the dispensing portion. The dispensing portion (5) is pivotally connected to the edge (6) of said one side (7) of the storage portion (4), which slopes away inwardly from the dispensing portion in order to accommodate the folded-in dispensing portion. The invention also includes a combination package which comprises said container (1) and an outer cover (2, 2′). The outer cover has a rectangular shape and includes walls (14, 15) fitting around the filled container and having a portion allowing the passage of the dispensing portion when in use.

Abstract: The invention relates to a device coupled to a fluid container. The device contains a fluid inlet and a fluid outlet and is capable of dispensing fluid into the fluid container. The device also contains an alarm to warn a user that the container is substantially empty.
