There are two types of lubricant introduction devices. One is for oil, the other for grease. They look so close they often get mixed up and the wrong material inserted into the wrong places.
An oiler (the iconic US manufacturer is Gits... our UK members can have a good laugh, now) And they look like this:

There is a small hole in the bottom of the "can", a spring, and a ball. The spring-loaded ball keeps junk out of the oil galleries.
A grease nipple is a different creature all together.
A grease gun has a spring loaded clip which grabs onto nipple, hence the iconic shape.
