  • Publication number: 20110135535
    Abstract: A sterile enclosure contains a transfer module defining a window. A port covers the window to maintain the inside of the enclosure as a sealed and sterile environment. A sliding, heated cutting element mounted on the port serves to sterilize and sever a portion of a sterile transfer bag assembly attached to the port. Preferably, the excised portion of the sterile transfer bag assembly is affixed to the port when the port opens. The sliding cutting element remains extended and heated to prevent contamination when the port is open. Further, a heating element is mounted about the window in order to sterilize around the opening when the port is open.

  • Patent number: 7954521
    Abstract: A container and method are provided for storing fat containing liquid products. The container includes a body defining a storage chamber for receiving the product, and a container closure. A first material portion forms at least most of the surface area overlying the storage chamber that can contact any product therein. Neither the body nor the first material portion leach more than a predetermined amount of leachables into the product or undesirably alter a taste profile thereof. A needle penetrable and thermally resealable second material portion either (i) overlies the first material portion and cannot contact any product within the storage chamber, or (ii) forms a substantially lesser surface area overlying the storage chamber that can contact any product therein in comparison to the first material portion. A sealing portion is engageable with the body to form a substantially dry hermetic seal between the container closure and body.

  • Publication number: 20110113729
    Abstract: Apparatus for molding and filling a device having a body defining an opening in communication with an interior chamber for receiving a substance therein, and a closure including a penetrable and resealable portion for sealing the opening and substance received in the device. A mold includes within the aseptic chamber plural mold cavities shaped to form the closure and body, and substantially sterile surfaces extending about and contiguous to the peripheries of the mold cavities. An assembly device including end-of-arm tooling having an engaging portion engageable with each of the body and closure is movable relative to the mold to engage and de-mold the substantially sterile closures and bodies from the mold cavities. Flexible barriers are coupled to the mold and the tool to substantially prevent the passage of contaminants from the molding machine and tool therethrough.

  • Publication number: 20110061763
    Abstract: A device defining a chamber for receiving a substance and a thermoplastic portion in fluid communication with the chamber is provided along with a method of filling and sealing the substance within the chamber. The thermoplastic portion defines a penetrable region that is penetrable by a filling member and is heat resealable to hermetically seal an aperture therein by applying laser radiation at a predetermined wavelength and power. The thermoplastic portion comprises a thermoplastic body defining a predetermined wall thickness and includes a styrene block copolymer, an olefin and a predetermined amount of pigment allowing the body to absorb laser radiation at the predetermined wavelength, substantially prevent the passage of radiation through the predetermined wall thickness, and hermetically seal the aperture in the penetrable region in a predetermined time period.

  • Patent number: 7905257
    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 another sterilizing chamber, such as an e-beam chamber, to sterilize the penetrable surface. A needle is 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. Laser energy is then transmitted onto the penetrated surface of the stopper to fuse the stopper material and hermetically re-seal the stopper.

  • Patent number: 7850051
    Abstract: A device including 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 member formed of an elastic material overlies the valve seat, defining a normally closed, axially-extending valve opening therebetween. The valve member is movable between a normally closed position engaging the valve seat, and an open position with at least a segment of the valve member spaced away from the valve seat to connect the valve opening in fluid communication with the flow aperture. A hermetically sealed variable-volume storage chamber stores therein multiple portions of the fluid and is connectible in fluid communication with the one-way valve assembly.
