  • Publication number: 20080053565
    Abstract: Disclosed is a uniquely configured medicament vial assembly which includes a storage vial, a stopper member and a securing ring. The vial assembly is configured to improve healthcare worker safety by providing a shielded gripping location to aid in the reduction of accidental needle sticks. The storage vial has a body portion which defines an interior chamber for storing a predetermined medicament and a neck portion through which medicament is received into and withdrawn from the interior chamber. The stopper member is inserted into the mouth of the vial and establishes a first seal. The securing ring is engaged with the mouth of the vial and adapted and configured for retaining the stopper member within the vial mouth and effectuating a second seal. The securing ring is formed from a thermoplastic and/or elastic material. Preferably, the securing ring is formed by molding the thermoplastic and/or elastic material over a portion of the storage vial and stopper member when engaged within the vial mouth.

  • Publication number: 20080044218
    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.

  • Publication number: 20080039773
    Abstract: A device and related method are provided for lyophilizing a substance within the device and storing therein the lyophilized substance. The device is penetrable by a needle for filling the device with the substance to be lyophilized, and a resulting needle hole in the device is laser resealable by transmitting thereon laser radiation from a laser source. The device defines a chamber for receiving therein the substance to be lyophilized. 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 with the substance to be lyophilized through the needle, and is laser resealable to hermetically seal the needle aperture by applying laser radiation thereto.

  • Patent number: 7328729
    Abstract: A dispenser for holding multiple doses of fluids or other substances, and for dispensing the substances, has a variable volume storage chamber. 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 dispensing valve is coupled in fluid communication with the storage chamber 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 fluid therethrough. The sealed, empty dispenser is sterilized, such as by applying gamma radiation thereto.

  • Patent number: 7322491
    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.
