Abstract: A container having a pouring spout for pouring oil into an engine (14). The container has a cap (24) which is screwed onto a neck portion (16) of the container. The cap (24) has radial ribs (32) tapering toward the cap bottom (28). The end of the neck portion (20) has a reduced diameter and is aligned with a breakable portion (28a) formed in the cap bottom.

Abstract: By employing two independent, separate and distinct flow paths which are controllably sequentially opened during use in a single actuation operation, an error-free, spill-free flame and explosion proof liquid delivery/filling system is achieved. In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configuration, requiring an actuation force to controllably, sequentially open the flow paths.
