Abstract

An apparatus for dispensing liquid or slurried products, in particular detergents and rinse aids for industrial cleaning processes, typically but not exclusively dishwashing machines. Replaceable containers are fitted directly to a receptacle on the operative part of the machine and the liquid product is easily dispensed from the container into the machine without spillage or soilage of user'"'"'s hands. The apparatus is characterized by self-sealing around a hollow penetrating device that can be inserted when in use, at the lowermost portion.

Claims

1. An apparatus for dispensing liquid or slurried products comprising:

(a) a container for a liquid or slurried product said container having an outlet which is covered by a self sealing septum said septum having slits therein;

(b) a receptacle for receiving said container with the said septum lowermost, said receptacle having a blunt hollow penetrating device for forcing part said slit, the septum around said slit sealing around said penetrating device to prevent leakage;

(c) means connected to said penetrating device for dispensing liquid or slurried products from said container;

(d) said container having means for allowing ingress air as produce is dispensed from the container; and

(e) wherein the slit eliminates the need for piercing the septum with said hollow penetrating device and said septum is self sealing before penetration and after the penetrating device is removed.

2. An apparatus of claim 1 wherein said septum is made of a rubber elastomer material.

3. An apparatus of claim 1 wherein said container has a collapsible liner for containing said product.

4. An apparatus of claim 1 wherein said penetrating device is a spigot mounted on said receptacle.

5. An apparatus of claim 1 wherein said receptacle is part of a wall-mounted dispensing device.

6. An apparatus of claim 1 wherein said container has a cap covering the septum, the cap having an aperture formed therein in-line with the slit of the septum, and further wherein said cap aligns the penetrating device with the slit in the septum.
