Oil Filter Cup

The Oil Filter Cup (referred to herein as "oil filter cup" and "tool") is a simple hand tool for controlling spillage of motor oil while removing oil filters during oil changes. It is designed to be used in conjunction with an ordinary socket wrench and oil filter socket.

Removal of an oil filter from any vehicle is messy, but in recent years, automobile manufacturers have exacerbated the problem by locating oil filters in poorly accessible locations. The result has been an unnecessarily messy job for the person removing the filter and environmentally undesirable oil spillage onto chassis and suspension components (and consequently, roadways); and the work area.

The Oil Filter Cup contains the oil seepage that results from breaking the seal between a vehicular oil filter and its' mounting fixture. This small feat is accomplished by attaching an ordinary oil filter socket to the male socket wrench component inside the oil filter cup; and an ordinary socket wrench to the female socket wrench component at the base of the oil filter cup. The oil filter cup is then placed over the vehicular oil filter; and pressure exerted against the ordinary socket wrench to break the seal between the oil filter and its' mounting fixture. When the seal is broken, oil seeps down the outside of the oil filter, but is contained by the oil filter cup. Thus, an oil filter in a poorly accessible location can be removed without discharging oil onto the vehicle or the work area.

I have designed the Oil Filter Cup to serve as a component of the ordinary socket wrench system. The Oil Filter Cup is a logical and economical solution to the annoying problem of uncontrolled oil discharge when the seal between an oil filter and its' mounting fixture is broken.

1. This tool allows oil seepage from the broken seal between a vehicular oil filter and its' mounting fixture to be contained during the removal procedure.

2. This tool allows oil seepage from a vehicular oil filter to be controlled until the oil can be directed into a suitable container.

An Oil Filter Cup comprises: a containment vessel (1); a metal block (2) with a male socket wrench component (3) to receive an ordinary oil filter socket at one end, and a female socket wrench component (4) to receive an ordinary socket wrench at the other end; a metal flange or washer (5), joined to the metal block, to form a bonding surface with the cup; a resilient washer (6) to seal the joint; a spring loaded ball bearing tensioner (7) to hold the ordinary oil filter socket on the male socket wrench component in the cup.
