Everyone knows Soylent Smoothie is people.  When released from its cryo cup, it can:
 
- set off life sign detectors
- scare monsters
- take orders communicated to it through its straw
- shapeshift into animals, plants, shapes of organic keys
- activate biological security panels
- seek its brethren by climbing toward a vat of Soylent sludge, ruining equipment and barriers in its path
 
Naturally, once empty, the cryo cup can be used to:
 
- capture small fast-moving animals or robots
- carry radioactive rods or other small hot objects
- manufacture ice cubes from a coffee dispenser
- put Little Lord Galgafrans the Complainer in stasis until he can be smuggled into the senate chamber and released to annoy the High Council
 
It sounds like you're more interested in advertising slogans/product warnings than puzzle ideas, but maybe it's helpful to know that these ideas are obvious enough to use for puzzles. If they occurred to me, they'll probably occur to the average player.
