In the FWIW Dept. I've found that a plastic 35mm film tin will keep a near lifetime supply of grease in a hard case or your kit & keep it clean and uncontaminated as well. Your pharmacist or vet. will likely give you a plastic syringe or two for the asking & as Stan has mentioned, they make for quick and effective dispensers. I use them as well, but they can be a liability in a travel application. I use electrical 'wire nuts' as a stopper on my plastic syringes to keep contaminates off or excess grease from being inadvertently ejected/extruded and I don't fly with them. Some countries will confiscate anything identifiable as oil or grease when they inspect the guns, their packing &c. Just saying. OTOH, a tube of 'lip balm' will go most anywhere w/o questioning.
