Abstract
A method of forming a container includes providing a mold including at least one bulbous protrusion. The mold is closed to form a mold cavity corresponding to the shape of the container, with the bulbous protrusion being positioned in the mold cavity. Material is injected into the mold cavity to form the container, and the material envelopes the bulbous protrusion to create an undercut slot. The container is removed from the mold and the bulbous protrusion is withdrawn from the slot.
