  • Publication number: 20050173020
    Abstract: A sterile filling machine and related method are provided for sterile filling a container with a substance. The container includes a heat resealable stopper and a chamber for receiving the substance therein. The sealed, empty containers are subjected to radiation capable of penetrating through the stopper and chamber for sterilizing the container. The previously sterilized containers are then transported through an e-beam chamber, wherein an electron beam is directed onto a penetrable surface of the stopper to sterilize the penetrable surface. A needle is mounted within the e-beam chamber and moved into engagement with the stopper to pierce the sterilized penetrable surface of the stopper and inject the substance through the needle and into the chamber of the container. The needle is then withdrawn from the stopper and the filled container is transported outside of the e-beam chamber.

  • Publication number: 20050165368
    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.

  • Publication number: 20050155987
    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: 20050150903
    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 that is connectable to the first connecting portion of the container for fixedly securing the valve assembly to the container when the valve assembly and container are located in the second position.

  • Publication number: 20050127693
    Abstract: A contact lens transfer device for transferring a contact lens from a storage container to a contact lens applicator has a body and a contact lens holder movably mounted on the body. The contact lens holder defines a contact lens support surface, a fluid-flow aperture extending through the contact lens support surface, and a chamber coupled in fluid communication with the fluid-flow aperture. A contact lens is removably receivable on the lens support surface, and the fluid-flow aperture is coupled in fluid communication with an interface between the contact lens and lens support surface for introducing fluid from the chamber, through the fluid-flow aperture and into the interface to release the lens from the lens support surface.

  • Publication number: 20050089358
    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: 20050000591
    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: 20040256026
    Abstract: A resealable cap (110, 210) for a medicament vial (114, 214) has a base portion (112, 212) formed of vulcanized rubber or like material known for providing a stable environment for the medicament contained within the vial, and a resealable portion (126, 226) overlying the base portion. The resealable portion (126, 226) is made of low-density polyethylene or like material, and can be punctured by a needle or like injection member (140, 282) for dispensing medicament into the vial (114, 214). Prior to filling, the cap (110, 210) is assembled to the vial (114, 214) and the cap/vial assembly is sterilized. Then, a needle (140, 282) is inserted through the cap (110, 210) and medicament is introduced through the needle and into the vial. Upon withdrawal of the needle (140, 282), the penetrated region of the cap (248) is fused by laser (276) or direct heat sealing (264) to hermetically seal the needle hole (294) in the cap.

  • Publication number: 20040245289
    Abstract: A dispenser for dispensing a fluid includes a rigid vial that has a main fluid chamber containing a fluid, and a pump assembly that is in fluid communication with the main fluid chamber and is configured to dispense a predetermined quantity of fluid from the main fluid chamber. A flexible bladder is provided which is located within the main fluid chamber and is configured to expand to fill the ullage created within the main fluid chamber during dispensing of fluid by the pump assembly. The resilient bladder tends to force itself outwardly toward the rigid vial and, in turn, increases the pressure within the main fluid chamber in comparison to the interior of the bladder to thereby prevent the ingress of air or vapors through the bladder or otherwise into the main fluid chamber.
