A container and closure assembly, affording a simple, quick, ergonomical, and reliable closing operation, provides an intermediate, partly open position that is reliably indicated. The distance of rotation of the closure relative to the container necessary for closing the closure is short, so that quick and simple closing of the container is provided. The closure is mounted to the container by a projection that is cooperatively received in a track. Either the closure or the container may be provided with the projection, the other being provided with the track. In a preferred embodiment, the track includes a protuberance that hinders the movement of the projection past a predetermined position along the track. When a user turns the closure positioned on the container, the engagement between the protuberance and the projection provides a tactile indication to the user during passage of a specific position of the closure on the container, while also preventing the unintentional movement of the closure past the protuberance.

[ What is claimed is:] [1.] A closure for closing an opening in a container, the container having a projection adjacent the opening, the closure comprising:a circumferentially extending guiding channel defined by opposed walls that are located and configured to receive between them the projection on the container when the closure engages the container, the guiding channel having an end in the closing direction and a starting point, between which the guiding channel includes (a) a first axial inclination along a first stretch of the guiding channel in a closure closing direction of movement of the projection along said guiding channel, (b) a second axial inclination along a subsequent second stretch of the guiding channel, and (c) a third axial inclination along a subsequent third stretch of the guiding channel; andfirst hindering means in the guiding channel that cooperate with the projection, during rotation of the closure relative to the container, for hindering movement along the guiding channel of the projection past a predetermined first position along the guiding channel and for providing a tactile indication during rotation of the closure on the container when the projection passes the first position;so that the closure is (a) positionable on the container in an open position, from which position the closure is removable from the container without rotation of the closure, and (b) rotatable about an axis in relation to the container, whereby the closure is movable repeatedly back and forth between the open position and a closed position, with provision of a tactile indication when the closure is moved between the open position and the closed position.
