example 1

[0064]In an exemplary embodiment, preservative free opthalmological products are amenable to storage and dispensing from reservoirs using the continuously sealing one way valve assembly and delivery system of the present invention. For example, eye drops, and preferably those eye drops involved in chronic care, for example, dry eye, glaucoma, allergies and NSAIDs, and also those eye drops intended for acute care, for example during ocular surgery, are amenable to storage and dispensing from reservoirs using the continuously sealing one way valve assembly and delivery system of the present invention. As a further example, those eye drops used to relieve eye fatigue, those eye drops used to relieve dry eye, those eye drops used relieve dry eye due to computer use, television use, or fatigue due to prolonged awake periods are amenable to storage and dispensing from reservoirs using the continuously sealing one way valve assembly and delivery system of the present invention.

example 2

[0066]In an exemplary embodiment, preservative-free otorhinolarygological products are amenable to storage and dispensing from reservoirs using the continuously sealing one way valve assembly and delivery system of the present invention. For example, nasalia medicines, and preferably nasal sprays, external ear creams, ear drops, steroid ear drops, antibiotic ear drops, nose drops, and nose drops comprising phenylephrine 0.25% and pseudoephedrine 30 mg, are amenable to storage and dispensing from reservoirs using the continuously sealing one way valve assembly and delivery system of the present invention.

example 3

[0067]In an exemplary embodiment, preservative free dermatological products are amenable to storage and dispensing from reservoirs using the continuously sealing one way valve assembly and delivery system of the present invention. For example, preservative free skin preparations; scalp preparations; corticosteroid creams, lotions and ointments; topical antibiotics and topical anti-fungal agents are amenable to storage and dispensing from reservoirs using the continuously sealing one way valve assembly and delivery system of the present invention. Thus, these preservative free dermatological products are amenable to storage and dispensing from reservoirs using the continuously sealing one way valve assembly and delivery system of the present invention because they are preservative free formulations.

Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. patent application Ser. No. 11 / 267,868, filed Nov. 3, 2005, and U.S. Provisional Patent Application Ser. No. 60 / 823,462, filed Aug. 24, 2006, each of which are incorporated by reference herein in their entirety.FIELD OF THE INVENTION[0002]The present invention is directed to a dispensing and delivery system including a continuously sealing one way valve assembly for dispensing a sterile flowable substance, which can include preservatives or be preservative free, while preventing a backflow of contaminants into the source of the flowable substance. The dispensing and delivery system includes, for example, a valve assembly enclosed by a pressure displaceable flexible member or elastomeric member for effecting the passage of the flowable substance to a controllable outlet, while preventing any backflow to the source of the flowable substance after dispensing individual portions or doses of the flowabl...
