Abstract

The present invention provides a motor oil change kit, especially for use by do-it-yourselfers, in which all that is needed for conveniently and cleanly changing the oil may be packaged together in a way that increases the chances that the motorist will not become intimidated by the project, but become habituated to this way of getting the oil changed, and that increases the chances that the motorist will unerringly bring the used oil to an authorized collection facility. Four types of kit are shown, each with its own advantages, but with many features in common. Each provides a closeable container of new oil, a collector for used oil, and a convenient system for either closing the container used for collecting the used oil, or for transferring the used oil from the collector to the emptied closeable container in which the new oil had been contained.

Dependent claims

A motor oil change kit comprising:

a jug of molded plastic material for initially containing a quantum of new oil sufficient to fill the engine oil reservoir of a motor vehicle internal combustion engine, said jug having at least one neck provided with a respective recloseable cap which at least one neck is located in the vicinity of the top of the jug when the jug is upright;
an outer container of molded plastic material, which initially receives and substantially encloses said jug, said outer container having a volumetric capacity at least as large as said quantum, and being capable of free-standing without need for being confined by a container box;
and
securement means initially retaining said jug received within and substantially enclosed by said outer container;
said outer container initially completely enclosing said jug;
said outer container further including a lid which constitutes a front wall of said outer container when said jug is upright and which constitutes a top wall of said outer container when said outer container is disposed as a receiver for used oil;
said outer container having a body including an opposite wall from said lid and a peripheral wall perimetrically bounding said opposite wall;
said perimetrical wall ending in a perimetrical lip distally of said opposite wall;
said lid including a perimetrical groove adapted to frictionally, removably securely receive said lip for removably sealingly securing said lid on said body of said outer container both when said jug is contained within said outer container and when said jug is outside said outer container and said outer container is full of used oil;
one said neck projecting vertically upwardly from said jug when said jug is upright;
said sidewall of said body of said outer container including means defining a pocket for receiving said one neck and the respective recloseable cap;
and
said lid of said outer container including a corresponding appendage for covering said pocket, said lip extending around said pocket and said groove extending around said appendage.

an outer container of molded plastic material, which initially receives and substantially encloses said jug, said outer container having a volumetric capacity at least as large as said quantum, and being capable of free-standing without need for being confined by a container box;
and
securement means initially retaining said jug received within and substantially enclosed by said outer container;
said relcoseable cap for one said neck of said jug including, in addition to a cap end wall having a threaded skirt, an inner structure comprising a rod coaxially secured at one end thereof to and extending inwardly from said cap end wall and having a threaded plug disposed on the opposite end thereof;
said outer container including a body having an inner end wall adapted to function as a floor when said outer container is disposed in turkey roaster orientation for collecting and containing used oil, and a peripheral sidewall for perimetrically integrally joining said inner end wall and adapted to function as an upstanding sidewall when said outer container is disposed in said turkey roaster orientation;
means providing an internally threaded drain opening in said inner end wall, correspondingly threaded with said plug, so that said recloseable cap may be unthreaded from said jug and, after said jug is removed from said outer container, said plug may be threaded into said drain opening from within said outer container to removably stopper said drain opening and leave said recloseable cap projected substantially above said floor of said outer container;
said rod being of sufficient length that when said quantum of used oil has been drained into the outer container, said recloseable cap remains disposed above the used oil and free to be grasped and rotated for removing the plug from the drain opening;
and
said jug and said outer container having cooperable surface means whereby said outer container, when stoppered and containing said quantum of used oil may be rested upon said jug with said drain opening, though stoppered by said plug, disposed in an open said neck of said jug, after said jug has been emptied of new oil, and said plug removed to allow the quantum of used oil to drain from said outer container into said jug, whereupon said jug may be reclosed using said recloseable cap.
