In the office kitchen, the pouch of milk in the micro-fridge
attached to the coffee maker does not end well. It ends with

The micro-fridge should be higher up, and the milk
should hang in it upside down, connected to the milk hose with
a Froth-Milk Vessel Inversion Adapter.
For a plastic bottle of milk, this could be a threaded, washable
silicone sphincter. The bottle would be supported in an
For milk pouches, such as we have, (and for tetra-paks), it

like those used in hospitals with intravenous drips.
