Abstract:
A device for storing and dispensing a substance includes a container having a body defining therein a storage chamber for receiving and storing the substance. The container includes a head located at one end of the body and a first passageway that is in fluid communication with the storage chamber of the body and defines a flow path therebetween. The container also includes a pierceable wall located on an opposite side of the passageway relative to the storage chamber, and a first connecting portion for connecting another component thereto. The device also includes a one-way valve assembly that includes a valve body including a body base defining a second passageway and at least one piercing portion engageable with the pierceable wall of the container. The valve assembly includes a second connecting portion connectable to the first connecting portion of the container for fixedly securing the valve assembly to the container.
Abstract:
A dispenser is provided for the delivery of controlled, metered amounts of any of numerous different substances to humans or animals, such as medicaments, pharmaceuticals, cosmetics, and food products, or to deliver materials that may react upon exposure to air, such as glue. Means are provided in the dispenser to effect controlled delivery of a pre-determined amount of the substance contained in the dispenser. A one-way valve is provided to hermetically seal the portion of the dispenser containing the substance to be dispensed.
Abstract:
A dispenser for dispensing a substance, such as a liquid lipstick or other cosmetic, pharmaceutical or cosmeceutical product, has a body with a variable-volume storage chamber for storing the product. A dispensing portion is connected with the body and a one-way valve for dispensing amounts of product therethrough. The dispensing portion defines a compression chamber in fluid communication with the storage chamber for receiving product therefrom, and an outlet aperture coupled in fluid communication with the compression chamber. The one-way valve has a valve seat, and a visco-elastic valve cover seated on the valve seat and defining a normally-closed, axially-extending seam therebetween forming a fluid-tight seal between the valve cover and valve seat. The flexible valve cover is movable relative to the valve seat, and the seam is connectable in fluid communication with the outlet aperture to allow the passage of product through the seam and out of the dispenser. An actuator is drivingly connected to the compression chamber for pressurizing product within the compression chamber and dispensing an amount of product within the compression chamber.

Abstract:
A flexible pouch and valve assembly is provided for aseptically storing a substance, dispensing multiple portions of the stored substance therefrom, and maintaining substance remaining in the pouch in an aseptic condition sealed with respect to ambient atmosphere. The flexible pouch and valve assembly are receivable within a relatively rigid housing, and are adapted to cooperate with a pump for pumping discrete portions of substance from the pouch and through the one-way valve to dispense the substance therefrom. The assembly comprises a flexible pouch defining therein a variable-volume storage chamber sealed with respect to the ambient atmosphere for aseptically storing therein multiple portions of the substance. A one-way valve of the assembly includes a valve body defining an axially-extending valve seat and at least one flow aperture extending through the valve body and/or the valve seat.
Abstract:
An ophthalmic delivery device includes a body defining a fluid reservoir and a pump in fluid communication with the reservoir. The delivery device also includes a nozzle that includes a dosage chamber for holding a dosage of fluid, a valve seat, and a valve cover. The valve cover extends about the valve seat and forms an interface therebetween and the valve seat includes an outlet aperture. The interface is in fluid communication with the outlet aperture and the dosage chamber, and at least part of the valve cover is movable between (i) a closed position with the valve cover engaging the valve seat to close the interface and form a fluid-tight seal therebetween, and (ii) an open position with at least part of the valve cover spaced away from the valve seat in response to fluid flowing through the outlet aperture at a pressure greater than a valve opening pressure to allow the passage of pressurized fluid therebetween. The valve seat and the valve cover are dimensioned to dispense the dosage of fluid through the interface at a velocity of equal to or less than 6 meters per second.
