Abstract
A grease gun is provided comprising a body having a reservoir bore with a plurality of grooves; a grease reservoir is in communication with the reservoir bore and has a reservoir groove on an outside surface of the reservoir. A retention fastener is received by a groove and is in operational engagement with the reservoir groove to removably retain the reservoir. The retention fastener may be connected to a fastener bracket via an aperture. The bracket is connected to a push-button via a connection mechanism. The grease reservoir may be removed or mounted to the connection aperture by exerting force on the button which transfers the force to the bracket via the connection mechanism. The force causes movement of the bracket along the aperture which deforms the retention fastener to allow the grease reservoir to be mounted/removed.
