A dispenser has a main hollow housing with side walls, a base and an open top which is at least partially open for dispensing material. A vertical support column is slidably mounted within the housing with horizontal ratchets and a push plate on top. A trigger component within the main hollow housing is movably connected to the housing and to the horizontal ratchets, and has an advancer arm, an opposing retractor arm and a flexible spring. The trigger component acts as a trigger, a ratcheting member and a spring and is strategically positioned in a swingable manner such that it may be rotated inwardly and released outwardly to cause advancement or retraction of the vertical support column.

The present invention is a container dispensing cap closure, which includes a container, a circular base and a pivot cap. The container has a neck, an open top and external threading for affixing a circular base thereto. The circular base has a circular inside wall with internal threading for attachment to the neck of the container. The circular base has an inwardly flexible leveraged sidewall trigger with a catch thereon which, when flexed inwardly, engages and pivots a pivot cap upwardly into an open position. The circular base has an upwardly extending guide-wall that regulates the pivotal rotation of the pivot cap, and an opening from which contents may be dispensed. The pivot cap is attached to the circular base by a clasp-element which is attached to two raised sidewall tracts located on the top of the circular base. The raised sidewall tracts comprise impressions which interact with snap-in-bead protrusions located on the clasp-element, thus allowing the pivot cap to pivot thereabout. The snap-in-bead protrusions and impressions are in frictional contact thus stabilizing the pivotal rotation of the pivot cap. The pivot cap also has a flat top and a lip which extends downwardly about the perimeter of the pivot cap. When the pivot cap is in a closed position the lip rests upon the top of the circular base. The pivot cap has a plug which, when the pivot cap is in a closed position, seals the opening on the circular base.

The present invention is directed to a blister pack opener which includes a structure designed to receive a soft pack of individually segregated unit dosages of medication. The opener or soft pack puncturing mechanism has a first component, a second component and a third component which are hingedly connected to one another. The first component is a blister pusher and has a unit dosage section base protrusion thereon. The second component is a blister positioner and has an orifice located thereon which is of sufficient size to receive a unit dosage section of a soft pack commonly referred to as a 'blister' and the third component is a blister cutter/ejector and has a cutting protrusion adapted to nest within the orifice of the second component and around the base protrusion of the first component so as to cut the packaging and eject the cut piece of the packaging along with the pill. Thus, the cutting protrusion has sufficient height so as to puncture a blister or dosage unit section of a soft pack medication. When a pack is placed within the first component so that dosage unit or 'blister' is placed within the orifice of the second component, and then the second component and third component are hingedly pushed downwardly, the cutting protrusion on the third component will puncture the foil or flat element of the blister pack. Preferably, the cutting protrusion has toothed edges on this protrusion to enhance puncturing.

The present invention involves a dispenser. The dispenser includes a main hollow housing with side walls, a base and an open top which contains a manifold component for dispensing material therethrough. At least one vertical support column is included within the hollow housing and it has horizontal ratchets thereon as well as a push plate located at its top. A trigger component is also contained within the housing and it is formed of plastic material with at least one flexible portion therein. It acts as a trigger, a ratcheting member and a spring, and is strategically positioned in a hinged manner such that a side wall cut-out or other member holding the trigger component against the vertical support column ratchets may be rotated inwardly and released outwardly to cause the ratcheting mechanism to advance the support column. Thus, the trigger component has a first position and a second position wherein, when it is moved from the first position to the second position, it advances the vertical support column upwardly and when it is released and moves from its second position back to its first position, it retreats to the next lower ratchet on the support column and is set for the next advance. In one preferred embodiment, the main hollow housing has two separate components for ease of manufacturing and assembling.
