Abstract
The present invention is a semi-flexible captive cap closure which includes a non-removable cap that rotates between a closed and open position and has opposing squeeze points that must be biased inwardly in order to open the cap. The preferred embodiment of the present invention includes a container which has a base and a neck for retaining the cap. The neck has at least one inclined recess track which has at least one impression which is adequately sized to correspond to a protrusion located on the cap. When the cap is in a closed position a user grasps the cap at the opposing squeeze points and applies inward pressure in order to displace the protrusion from the impression and to allow rotation to an open position. The cap is maintained in an open position either by frictional contact between the track and protrusion or by a second corresponding impression. The cap further includes a dispensing orifice which is closed by the neck of the container when the cap is in a closed position and opened when the cap is in an open position.
