  • Patent number: 7290573
    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.

  • Patent number: 7278553
    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. An elastic valve cover includes a valve portion overlying the valve seat, forming an interference fit with the valve seat, and defining an 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 allow the passage of fluid from the flow aperture through the valve opening. A hermetically sealed variable-volume storage chamber is connectible in fluid communication with the one-way valve assembly. A pump is coupled between the variable-volume storage chamber and the one-way valve assembly to dispense discrete portions of fluid through the valve assembly.

  • Patent number: 7270158
    Abstract: An apparatus is provided for needle filling and thermally resealing containers having stoppers that are needle penetrable for filling the containers with a substance, and are thermally resealable for thermally sealing a needle hole in the stopper upon withdrawal of a needle therefrom. A container support of the apparatus supports at least one container having a resealable stopper in a substantially fixed position during needle filling and thermally resealing a needle hole in the stopper upon withdrawal of a needle therefrom.

  • Publication number: 20070194045
    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.

  • Patent number: 7243689
    Abstract: A device and method are provided 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 of the device is pierceable with a needle to form a needle aperture therethrough to fill the chamber through the needle, and is laser resealable to hermetically seal the needle aperture by applying laser radiation at a predetermined wavelength and power thereto. 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 from the needle penetrable and laser resealable portion during penetration by and withdrawal of the needle.

  • Publication number: 20070156102
    Abstract: A syringe and a reconstitution syringe are provided for the delivery of controlled doses of any of numerous different sterile substances, such as vaccines, medicaments, pharmaceutical preparations, cosmetics, and food products. A plunger of the syringe defines a resealable stopper frictionally and slidably received within a hollow syringe body for dispensing the medicament or other substance through a dispensing tip of the syringe upon movement of the plunger. The resealable stopper defines a heat-sealable portion to allow the stopper to be penetrated by a needle or other filling device to fill the syringe with a medicament or other substance, and in turn allow the hole remaining upon withdrawal of the needle to be heat sealed by transmission of laser energy thereon.

  • Patent number: 7226231
    Abstract: A dispenser for dispensing a substance, such as a liquid lipstick or other product, has a body defining a variable-volume storage chamber for storing the product. A dispensing portion is connected with the body and defines a bore coupled in fluid communication with the storage chamber for receiving product therefrom, and an outlet aperture coupled in fluid communication with the bore. A piston is received within the bore, and a one-way valve is mounted on the dispensing portion for dispensing metered amounts of product therethrough. The one-way valve has an axially-extending valve seat, and an axially-extending 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.
