  • Patent number: 7445033
    Abstract: Device and method for needle penetrating and filling a chamber with a predetermined substance, and laser resealing a resulting needle hole in the device. A needle penetrable and laser resealable portion is pierceable with a needle to form a needle aperture therethrough to fill the chamber, and is laser resealable to hermetically seal the needle aperture by applying laser radiation. The needle penetrable and laser resealable portion defines a predetermined wall thickness in an axial direction thereof, and includes a thermoplastic that substantially prevents the formation of particles released into the chamber during penetration by and withdrawal of the needle.

  • Publication number: 20080149191
    Abstract: An apparatus has a valve body defining a first passageway, a valve seat, and a flow aperture extending through the valve body and coupled in fluid communication with the first passageway. A valve cover of the apparatus is formed of an elastic material and includes a cover base mounted on the valve body and fixedly secured against movement relative thereto, and a valve portion overlying the valve seat. The valve portion defines a predetermined radial thickness and forms an interference fit with the valve seat. The valve portion and the valve seat define a normally closed, axially-extending valve opening therebetween. The valve portion is movable between a normally closed position with the valve portion engaging the valve seat, and an open position with at least a segment of the valve portion spaced away from the valve seat to connect the valve opening in fluid communication with the flow aperture to thereby allow the passage of fluid from the flow aperture through the valve opening.

  • Publication number: 20080142112
    Abstract: A dispenser for holding multiple doses of fluids or other substances, and for dispensing the substances, has a vial, a flexible bladder received within the vial, and a variable volume storage chamber formed between the bladder and vial. A filling valve is coupled in fluid communication with the storage chamber and defines (1) a normally closed, fluid-tight position hermetically sealing the storage chamber from the ambient atmosphere, and (2) an open position allowing the passage of fluid through the valve both to evacuate the storage chamber and to introduce fluid through the valve to fill the storage chamber. A pump is coupled in fluid communication with the storage chamber for pumping fluids out of the storage chamber. A dispensing valve is coupled in fluid communication with the pump and defines (1) a normally closed, fluid-tight position preventing the passage of fluid out of the dispenser, and (2) an open position for dispensing pumped fluid therethrough.

  • Publication number: 20080135130
    Abstract: A syringe 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 which may react upon exposure to air, such as glue. The syringes include a body and a plunger. Means are provided in the syringe body and the plunger to effect controlled movement of the plunger into the syringe to permit delivery of a pre-determined amount of the substance contained in the syringe. A one-way valve is provided at the dispensing tip of the syringe to hermetically seal the portion of the syringe containing the substance to be dispensed.

  • Publication number: 20080121668
    Abstract: A container including a nozzle and body depending therefrom. The body is preferably tubular and defines an interior which retains a product to be dispensed. A cap engages the nozzle to prevent inadvertent release of the product. In order to dispense the product, the cap is removed and pressure is applied to the body and the nozzle allows release of the product. The nozzle releases the product without exposing the remaining product to the external atmosphere, thus the sterility of the interior of the body is maintained and the shelf life of the product is increased. The nozzle includes an inner body, coupled to the tubular body, surrounded by a flexible outer cover. A seam between the inner body and flexible outer cover forms a one-way release valve wherein a portion of the seam remains closed during dispensing the product.

  • Publication number: 20080116225
    Abstract: An apparatus for storing fluid and dispensing multiple portions of the stored fluid has a container defining a variable-volume storage chamber; a dispensing valve including a valve inlet coupled in fluid communication with the variable-volume storage chamber, and an elastic valve member in fluid communication with the valve inlet and defining a normally-closed valve opening; a manually engageable actuator; and a pump including a compressible member defining a compression chamber coupled in fluid communication with the variable-volume storage chamber. Multiple portions of the stored fluid are hermetically sealed in the variable-volume storage chamber. The actuator is manually engageable and movable between (i) a first position wherein the compression chamber defines a first volume, and (ii) a second position wherein the compression chamber defines a second volume less than the first volume.

  • Publication number: 20080118299
    Abstract: A dispenser for dispensing a substance has a body defining a variable-volume storage chamber for storing the substance, and a dispensing portion connected with the body and defining a dosage chamber coupled in fluid communication with the storage chamber for receiving substance therefrom, and an outlet aperture coupled in fluid communication with the dosage chamber. A first valve includes an axially-extending valve seat and an axially-extending flexible 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 substance through the seam and out of the dispenser.

  • Publication number: 20080116226
    Abstract: An apparatus for storing fluid and dispensing multiple portions of a stored fluid therefrom. The apparatus comprises a container defining a variable-volume storage chamber for receiving therein the fluid and a dispensing valve including a valve inlet coupled in fluid communication with the variable volume storage chamber, and a valve member in fluid communication with the valve inlet and defining a normally-closed valve opening. The valve member is responsive to fluid at the valve inlet exceeding a valve opening pressure to move between (i) a normally closed position, and (ii) an open position permitting fluid flow through the valve opening. The dispensing valve defines a dispensing axis defining a direction substantially along which fluid is dispensed from the valve, and further includes an outlet surface over which dispensed fluid flows oriented at an acute angle relative to the dispensing axis for preventing the collection of residual dispensed fluid thereon.
