As an alternative to recycling chapstick dispensers, all these work as well. (As I'm one of those who prefer using deodorant, and washing where I can)

Band-Aid Friction Block Stick .34 oz. (Already mentioned in Tyler's post)

Neutrogena Wet Skin Kids Stick 0.47 oz. There is also a Baby Version as well – same size

Bodyglide Anti-chafe Balm Pocket Size .21oz – somewhat awkward to use as a deodorant dispenser, but still works.
For me, the Band-Aid Friction Block size dispenser lasts a week (with one application per day)
No need to melt a commercial product, as the deodorants I use (which are not antiperspirants) easily "extrude" into the empty container.
