Abstract: A lid for use with containers having a peripherally disposed edge with a rolled inside edge positioned around the container opening. The lid has a flange with a first rim projecting downwardly therefrom. The first rim has an edge engaging section with a plurality of concentrically positioned snap rings that each have a concavely shaped contact surface facing outward from the first rim to engage a curved surface on the rolled inside edge. The first rim is tapered inwardly such that the lower snap rings have a smaller diameter than the upper snap rings to allow the container to select which snap ring provides the best fit for snap engagement with the curved surface. The snap rings are made out of a material that deforms to the shape of the curved surface. A second rim projecting downward from the flange outwardly of the first rim provides a dust shield.

Abstract: A system for transferring a viscous liquid between bottles that comprises a first bottle from which liquid is to be drained, a second bottle for receiving the liquid, a first bottle connector that attaches to the first bottle and a second bottle connector that attaches to the second bottle. Each bottle connector has a bottle engaging section that engages the bottle and a connection section that engages the connection section on an opposing bottle connector. Each connection section is genderless and comprises a plurality of outwardly extending members and a member receiving section between each adjacent members. When used to drain fluids from one bottle to another, an outwardly extending member of one connector is received in a member receiving section of the other connector to place the outwardly extending members in interlocking relation. The connection section can comprise a locking mechanism to lockingly join the two connectors together.

Abstract: A system for transferring a viscous liquid between containers that comprises a first container from which the liquid is to be drained, a second container for receiving the liquid, a first transfer lid that attaches to the first container, a second transfer lid that attaches to the second container and a transfer adapter that interconnects the lids. The first transfer lid has an outlet spout received into the transfer adapter, which is received in an inlet spout of the second transfer lid. The first container is inverted over the second container to drain liquid from the first container lid to the second container through the connected container lids. In an another configuration, the system is used with bottles and comprises a pair of bottle connectors that each engage a bottle and have interlocking members that join the connecters. In another embodiment liquid is transferred between a bottle and a container.
