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 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.
Abstract:
A container and valve assembly for storing and dispensing substances including edible substances. The container is a tubular body that defines a storage chamber for storing the substance and a head portion for supports the valve assembly. The valve assembly includes a valve body and a valve seat surrounded by a flexible outer cover that includes a valve portion. A seem between the valve portion and valve seat form a one-way release valve wherein a portion of the seam remains closed when the substance is dispensed. To dispense the substance, pressure is applied to the body forcing the substance into the valve assembly, which in turn, controls the flow and release of the substance without exposing the remaining substance to the external atmosphere; thus, the sterility of the storage chamber and remaining substance is maintained, and the shelf life of the substance is increased.
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.
Abstract:
An apparatus and method are provided for formulating and aseptically filling liquid products. A first liquid source includes at least one first liquid component; a second liquid source includes at least one second liquid component; and a container includes a body defining an empty, sterile storage chamber therein that is sealed with respect to ambient atmosphere. The container is introduced into a sterile filling chamber. A first filling member coupled in fluid communication with the first liquid source is placed in fluid communication with the storage chamber of the container located in the sterile filling chamber, and the first liquid component is aseptically introduced through the first filling member and into the storage chamber. A second filling member coupled in fluid communication with the second liquid source is placed in fluid communication with the storage chamber of the container located in the sterile filling chamber, and the second liquid component is aseptically introduced through the second filling member and into the storage chamber and, in turn, the first and second liquid components are combined into a liquid product formulation within the sterile chamber of the container. The first and second filling members are withdrawn from fluid communication with the storage chamber of the container located within the sterile filling chamber, and the filled storage chamber is sealed with respect to ambient atmosphere to hermetically seal the liquid product formulation within the storage chamber of the container.
Abstract:
A device and method are provided for needle penetrating and filling a chamber with a predetermined substance, and laser resealing a resulting needle hole in the device. 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 through the needle, and is laser resealable to hermetically seal the needle aperture by applying laser radiation at a predetermined wavelength and power thereto. The needle penetrable and laser resealable portion defines a predetermined wall thickness in an axial direction thereof, and includes a thermoplastic that substantially prevents the formation of particles released into the chamber from the needle penetrable and laser resealable portion during penetration by and withdrawal of the needle. The thermoplastic includes a predetermined amount of pigment that allows the thermoplastic to substantially absorb laser radiation at the 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.
