Abstract:
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.
