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.
A reservoir for the storage of liquid having an upwardly open filler passage terminating in an open end to receive a neck portion of a liquid container, a wall spanning said filler passage spaced inwardly from said open end thereof, and a conduit integral with said wall to define a passage therethrough and constructed at the upper end thereof to pierce a closure wall in the neck portion of the container upon the neck portion being inserted into the filler passage, a lateral opening in the wall of the conduit to communicate with the interior of the container after said piercing of the closure wall, said opening being located to inhibit direct axial communication between the filler passage and the interior of the reservoir, said conduit being adapted to inter-engage with the neck portion of the container at a level below the lateral opening in the conduit as the conduit is being received in the neck portion to form a seal herebetween before the closure wall is pierced.
A liquid reservoir comprising a reservoir body defining a closed chamber to receive liquid and having a delivery port, an upwardly open cavity within the reservoir body having a lower wall portion separating the cavity from the closed chamber and a conduit integral with said lower wall defining a passage therethrough and constructed at the upper end thereof to pierce an openable discharge port of a container upon the container being inserted into the upwardly open cavity, a lateral inlet port in the conduit to communicate with the interior of the container after said piercing of said discharge port, a container shaped so at least an end portion thereof is receivable in the cavity and having an openable discharge port in said end portion located to operatively communicate with the inlet port when the container is received within the cavity to thereby permit liquid to flow from the container into the closed chamber, said discharge and inlet ports being positioned in the container and cavity respectively so that they only operatively communicate when said portion of the container is received in the cavity in a single selected relative orientation of said container relative to the cavity of the reservoir body.
