A sealed delivery system for dispensing metered volumes of a pure or sterile flowable substance is presented. In exemplary embodiments of the present invention, a hand-held sealed delivery system comprises a continuously sealing one-way valve assembly at a distal end, and a volume reducing reservoir at a proximal end. The pure or sterile flowable substance can be stored in the volume reducing reservoir. In operation, a user pushes down upon a push button driven actuator assembly, acting upon a metering pumping chamber, which is in fluid communication with the pure or sterile flowable substance stored in the volume reducing reservoir via a check valve. Depression of the push button driven actuator causes a dispensing pump to push a metered volume of flowable substance through the continuously sealing one way dispensing valve assembly. Return of the push button driven activator to its home state causes the dispensing pump to pull a metered volume of the contained flowable substance from the volume reducing reservoir and through the check valve. In exemplary embodiments of the present invention, a continuously sealing one way dispensing valve assembly prevents any backflow of contaminants through the dispensing orifice when the flowable substance ceases to flow, while the materials and sealed assembly of the overall dispensing delivery system prevent other means of contamination of the remaining pure or sterile substance contained within. In exemplary embodiments of the present invention, one or more components of the continuously sealing one way dispensing valve assembly, or of the delivery system general, can be bacteriostatic, bactericidal, or both.

Delivery system for dispensing metered volumes of pure or sterile flowable substances

A sealed delivery system for dispensing metered volumes of a pure or sterile flowable substance is presented. Such system comprises a continuously sealing one-way valve assembly at a distal end, and a volume reducing reservoir at a proximal end, in which a pure or sterile flowable substance can be stored. In operation a user pushes down upon an actuator assembly, acting upon a metering pumping chamber in fluid communication with the reservoir via a check valve. Depression of the actuator causes a dispensing pump to push a metered volume of flowable substance through the continuously sealing one way dispensing valve assembly, and return of the actuator to its home state causes the dispensing pump to pull a metered volume of the contained flowable substance from the volume reducing reservoir and through the check valve.

A one way valve assembly flows a sterile flowable substance from a source to an outlet orifice and prevents any backflow of contaminants through the one way valve assembly when the flowable substance ceases to flow. The valve assembly includes an elastomeric membrane which aids in preventing any backflow of contaminants when dispensing of the flowable substance is stopped.

One way valve assembly

A reusable continuously sealing one-way valve assembly and delivery system flows a sterile flowable substance from a source to an outlet orifice and prevents any backflow of contaminants through the continuously sealing one way valve assembly when the flowable substance ceases to flow. The valve assembly includes an elastomeric membrane which aids in preventing any backflow of contaminants when dispensing of the flowable substance is stopped. Multiple dosing of preservative-free flowable substance is provided.

Continuously sealing one way valve assembly and fluid delivery system and formulations for use therein

A reusable continuously sealing metered dosing one-way valve assembly and delivery system flows a premeasured amount of a sterile flowable substance from a source which is coupled to an actuator assembly to an outlet orifice and prevents any backflow of contaminants through the continuously sealing one way valve assembly when the flowable substance ceases to flow. The valve assembly includes an elastomeric membrane which aids in preventing any backflow of contaminants when dispensing of the flowable substance is stopped. Multiple dosing of preservative-free flowable substance is provided.

Metered drop push button dispenser system

An enclosing sleeve for a one-way valve presses an elastomeric sheath against the valve body to provide a seal between the sheath and the valve body. In addition, the sleeve can form a closure over the outlet end of the valve body protecting it from contamination or contact with contaminating surfaces.

Enclosing sleeve for one-way valve

A collapsible container for dispensing a flowable substance includes a pair of generally rigid walls interconnected by bellows-like walls and a web. The container can be arranged in the expanded condition with the rigid wall spaced apart from one another and in the collapsible condition with the rigid walls disposed in generally parallel relation forming a flattened unit. The rigid walls provide an effective labelling surface for the container.

Collapsible container for flowable substances

A flexible, pleated container has a wall structure comprising a barrier component which renders the container wall structure impervious to oxygen and water vapor. The barrier component is substantially uniformly effective throughout the entire wall structure. In a preferred embodiment of the invention, the thickness of the wall structure gradually decreases towards the outer extremities of the pleats with the thinnest wall portion located at the apexes of the pleats. The barrier component, however, is maintained at substantially uniform thickness throughout the wall structure.

Flexible pleated container structure

A self-cleaning valve used at the outlet of a container has an elongated flexible flattenable tube with an inlet end for receiving material to be dispensed from the container and an outlet end for dispensing the material. In the at-rest condition of the valve, a section of the tube extending from the outlet end is supported between a housing surface and a closure-cleaning lever member spring-mounted on the housing so that it pivots about a fulcrum. By pressing down on one end of the lever member, the tube can be opened so that material, forced out of the container, can be dispensed from the outlet end of the tube. After the material has been dispensed, the lever member is pivoted along the outside surface of the tube pressing the tube against the housing surface so that any material remaining within the tube is forced out of the outlet end.

Self-cleaning valve

A valve for spraying material as a mist includes walls forming an elongated passageway having an inlet and an outlet. The passageway is flattened at least at the outlet end. The flattened portion has opposed walls disposed in contact and at least one of the surfaces of the flattened portion has a plurality of capillary-like channels. Upstream from the channels, the valve has a flexible wall section which vibrates at its natural frequency when the material to be sprayed as a mist is forced through the passageway out of the valve.

Valve for spraying a mist

A self-cleaning valve used at the outlet of a container has an elongated flexible flattenable outlet tube with an inlet for receiving material to be dispensed from the container, and an outlet for dispensing the material. In the at-rest condition of the valve, a pair of spring-biased rollers contact the opposite sides of the tube at a location spaced from the outlet end and hold the tube in a closed condition. When material is forced through the inlet end of the tube it pushes the rollers toward the outlet against the spring biasing action. At the outlet end the rollers separate and permit the tube to open so that the material can be dispensed. After the material has been dispensed, the springs return the rollers to the at-rest position and the rollers effect a self-cleaning action on the tube.

A method for manufacturing a container assembly adapted to store and dispense fluid material including a collapsible flexible container adapted to be stretched from an initial nominal position and to be collapsed to dispense fluid material stored therein, and a cap member adapted to be placed in operative engagement with a neck portion of the container configured to define a dispensing flow conduit which is placed in direct flow communication with the interior of the container when the cap member is mounted in assembled position on the neck portion of the container. In the manufacture of the container assembly, the container is first stretched from its initial nominal position to expand the volume thereof, and then filled with a fluid material to be stored therein and to be dispensed therefrom while in said stretched position. The cap member is then attached to the container by connecting the cap member in operative engagement with the upper neck portion, and the container is then released from the stretched position and allowed to return to the initial nominal position whereby a quantity of fluid material stored therein commences to be emitted from a check valve at the outlet end of the dispensing flow conduit thereby to completely fill the dispensing flow conduit in the cap member with the fluid material to be dispensed.
