Adapter for paint mixers

1. An adapter to hold a small paint container in an interior of the adapter and having an exterior shaped to be held in a paint mixer sized to hold a large paint container, the adapter comprising:

a first member fitted with spring clip attached to the first member at a proximal end of the clip and having a distal end of the clip shaped to define a catch, where the distal end of the spring clip is biased outward from the first member and extends through a first longitudinal slot on the first member bounded by a first bridge positioned to constrain outward movement of the spring clip; and

a second member hinged to the first member and having a second longitudinal slot on the second member bounded by a second bridge positioned to be aligned with the first longitudinal slot when the first and second members are rotated to be in close proximity to each other so that the distal end of the spring clip extends into the second longitudinal slot and engages the second member to secure the first member to the second member

wherein the second bridge includes a depression shaped to accept the catch of the spring clip when the spring clip is extended into the second longitudinal slot and the interior of the adapter is shaped to hold one of a conventional cylindrical quart container or a rectangular or square quart container.

2. The adapter of claim 1 wherein the spring has a generally S-shaped curve near the distal end thereof.

3. The adapter of claim 2 wherein the generally S-shaped curve forms the catch.

4. The adapter of claim 1 wherein the first bridge limits movement of the distal end of the spring to remain within an elastic limit range of the spring.
