Abstract
An oil reservoir for the supply of oil to an internal combustion engine, the reservoir 50 having an upwardly open filler passage 53 to receive a neck portion 64 of an oil container 64. The reservoir filler passage 53 being closed by a wall 54 spaced inwardly from the open end thereof and an opening 56 is provided in said filler passage wall 54 located to inhibit direct communication between the filler passage 53 and the interior of the reservoir 50. The filler passage 53 is adapted to sealably engage the container neck 65 upon the container neck 65 being inserted into the filler passage 53 a pre-determined extent, and to puncture a closure wall 70 of the container neck 65 after said sealed engagement is established to permit oil to flow from the container 64 through said opening 56 in the filler passage wall 54 into the reservoir 50.
