  • Patent number: 5967377
    Abstract: The present invention is a metered liquid dispenser. A liquid dispenser has a liquid volume metering element located on a base attached to the top of the neck of a liquid dispenser. Using a lift fill mechanism, the metering element is vertically slid relative to the base to dispense a measured liquid volume. One-way valves located in the base and the top of the metering element alternately act to displace air from the element, and then provide suction to draw a measured liquid volume from the liquid dispenser through a dip tube into the element. The liquid is dispensed by inverting the metered liquid dispenser. The metering element has liquid level markings to indicate the liquid volume being entered to the element for dispensing, and is preferable partly transparent to visually display the liquid in the metering element.

  • Patent number: 5860572
    Abstract: 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.

  • Patent number: 5853101
    Abstract: 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 base segment and a top segment hingedly connected to one another. The base segment 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 top segment has a protrusion adapted to nest within the orifice of the bottom segment. The protrusion of the top segment has sufficient height so as to puncture a dosage unit section of a soft pack of medication. When a dosage unit or "blister" is placed within the orifice of the bottom segment and the top segment is hingedly pushed downwardly, the protrusion on the top segment will puncture the foil or flat element of the blister pack. Preferably, the puncture mechanism has toothed edges on this protrusion to enhance puncturing.

  • Patent number: 5797517
    Abstract: A dispenser has a hollow housing with sidewalls, a base and a top. The top has a cylinder for receiving piston, and a catch for permitting limited movement of the piston within the cylinder. The piston having an inlet valve for allowing air into the cylinder. The cylinder has an outlet valve which forces air into the housing. The dispenser has a tri-purpose nozzle. The nozzle has a dispensing orifice at one end and is biased in an open up position. The piston is suspended from the bottom surface of the nozzle. As such, the nozzle acts as the pump for slidably moving the piston within the cylinder. The top has a fluid outlet port opposite the position of the cylinder. The nozzle is rotatably connected to the top. In addition, there is a structure for fluidly connecting the fluid outlet port to the nozzle.

  • Patent number: 5749496
    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.

  • Patent number: 5570821
    Abstract: 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 one of the vertical support column ratchets may be rotated inwardly and released outwardly to cause the ratcheting mechanism to advance the support column.

  • Patent number: 5551607
    Abstract: 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.
