  • Publication number: 20140252045
    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: 20140246462
    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.

  • Publication number: 20140246435
    Abstract: A container including a body defining an outflow opening and at least one chamber adapted for storing a product, such as a fat containing liquid product, and a container closure including a primary seal for hermetically sealing the product within the chamber during storage. The container closure includes a sealing member forming a substantially fluid-tight seal between the container closure and the body, and a dispensing member in fluid communication with the chamber. The container closure and body move relative to each other between a first position where the primary seal is seated about the outflow port to hermetically seal the product in the chamber during storage, and a second position where the primary seal is displaced from the outflow port to allow product to pass from the chamber through the outflow port and into dispensing member to dispense the product.

  • Patent number: 8672195
    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: 20140026973
    Abstract: A one-way valve is connectable in fluid communication with a fluid-receiving chamber, such as a dilution chamber or a mixing chamber for diluting or mixing a perishable food product, such as a milk product or chocolate product, and forming a substantially fluid-tight seal therebetween. The valve comprises a relatively rigid valve seat, and a relatively flexible valve member overlying the valve seat and forming an axially-elongated, normally-closed valve opening therebetween defining an inlet at one end of the valve seat, an outlet at an opposite end of the valve seat, and an axially-extending seal therebetween that forms a fluid-tight seal between the inlet and outlet of the normally-closed valve opening. An axially-extending valve body is radially spaced relative to the valve member and forms a space therebetween allowing fluid-flow therethrough for cleaning the valve and the fluid-receiving chamber.

  • Patent number: 8631838
    Abstract: Device and method for needle penetrating and filling a chamber with a predetermined substance, and hermetically resealing a resulting needle hole in the device by applying radiation thereto. The needle penetrable and resealable portion defines a predetermined wall thickness in an axial direction thereof, and may include a thermoplastic that substantially prevents the formation of particles released into the chamber from the needle penetrable and resealable portion during penetration by and withdrawal of the needle. Such thermoplastic may include a predetermined amount of pigment that allows the thermoplastic to substantially absorb laser radiation at a predetermined wavelength, substantially prevent the passage of radiation through the predetermined wall thickness thereof, and hermetically seal a needle aperture formed in the needle penetration region thereof in a predetermined time period.

  • Publication number: 20130333796
    Abstract: A device has a sealed chamber; a first penetrable septum in fluid communication with the chamber that is formed of an elastic material and is penetrable by a first injection member to fill the first chamber with a substance therethrough; and a second penetrable septum movable between first and second positions. In the first position, at least a portion of the second septum is spaced away from the first septum to allow the injection member to penetrate the first septum and aseptically or sterile fill the chamber with a substance therethrough. In the second position, the portion of the second septum overlies and seals a resulting injection aperture in the first septum after withdrawal of the first injection member therefrom, and is penetrable by a second injection member to penetrate the first and second septums and withdraw a filled substance from the chamber and through the second injection member.

  • Publication number: 20130318926
    Abstract: A sterile filling machine and related method are provided for sterile filling a container with a substance. The container includes a resealable stopper or portion and a chamber for receiving the substance therein. The sealed, empty containers are subjected to radiation capable of penetrating through the resealable portion 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 filling member is moved into engagement with the resealable portion to pierce the sterilized penetrable surface of the resealable portion and inject the substance through the filling member and into the chamber of the container. Energy is then transmitted onto the stopper to hermetically re-seal the penetration in the resealable portion.
