CONTAINER CLOSURE WITH SLIDE LOCK

摘要

A closure for a container is provided. The container has a neck (51) and a flange (52) on the neck. The flange has an opening (54). The closure comprises a cap having a top surface and a cylindrical wall. The cylindrical wall has a top end proximate to the top surface, a bottom end, and an arcuate opening (22) at the bottom end. An arcuate slide (30) is slidably mounted to the cap for axial movement. The slide is sized to cover the opening in the cylindrical wall. The slide has a retracted position and an extended position, such that the slide extends beyond the bottom end of the cylindrical wall when the slide is in the extended position. The slide is manually actuable to the retracted position. A biasing mechanism is provided for moving the slide towards the extended position, so that the slide extends into the opening in the flange when the cap is screwed onto the container. This limits rotation of the cap relative to the container.
