Abstract:
A device comprises a first portion including a first polymer, and a second portion that is relatively flexible in comparison to the first portion and includes a second polymer that is substantially not bondable to the first polymer. A chamber of the device is hermetically sealable with respect to ambient atmosphere and is defined by (i) an interior of the second portion, and/or (ii) a space formed between the first and second portions. A third portion of the device includes a third polymer that is bondable to the first and second polymers and fixedly secures the first and second portions to each other.
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.
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.

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.
Abstract:
A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.
Abstract:
A vial for storing multiple doses of a substance to be dispensed into one or more syringes or other delivery devices. The vial has a body, a variable-volume storage chamber within the body for storing multiple doses of the substance therein, and a one-way valve connectable in fluid communication with a syringe or other delivery device. The one-way valve is moveable relative to the body between first and second positions (i) one of which permits the valve to open so that substance from the variable-volume storage chamber can flow therethrough and into the syringe or other delivery device connected in fluid communication therewith, and (ii) one of which prevents the valve from opening.
Abstract:
A dispenser for dispensing a substance, such as a liquid lipstick or other cosmetic, pharmaceutical or cosmeceutical product, has a body with a variable-volume storage chamber for storing the product. A dispensing portion is connected with the body and a one-way valve for dispensing amounts of product therethrough. The dispensing portion defines a compression chamber in fluid communication with the storage chamber for receiving product therefrom, and an outlet aperture coupled in fluid communication with the compression chamber. The one-way valve has a valve seat, and a 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. An actuator is drivingly connected to the compression chamber for pressurizing product within the compression chamber and dispensing an amount of product within the compression chamber.
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. A seal is engageable with the fluid-receiving chamber and forms a substantially fluid-tight seal therebetween to seal the valve outlet and fluid-receiving chamber with respect to ambient atmosphere. The valve member is movable radially away from the valve seat in response to substance at the inlet to the valve opening exceeding a valve opening pressure to flow into the normally closed valve opening, through the outlet, and into the fluid-receiving chamber.
