Abstract: The invention concerns a packaging tube comprising a multi-layer pure plastic laminate and a sealing arrangement for tube heads for the packaging of materials with volatile substances such as flavouring or scent substances, which has a resistance to diffusion which is the same as or comparable to tubes which in their laminate structure have a metal layer as a diffusion barrier and which improves the recycling of tubes.

Abstract: A container made of a substantially dielectric material adapted to contain and preserve a perishable substance, comprising:a substantially elongated tubular portion defining an enclosure adapted to contain a perishable substance, the tubular portion being made from a flexible dielectric material, and defining an opening adapted to release said perishable substance through the opening by squeezing the tubular portion;a first magnet coupled to an interior wall of the tubular portion and extending substantially the length of the tubular position;a second magnet coupled to said interior wall of the tubular portion of a substantially opposite side of the tubular portion relative to the first magnet and facing the first magnetic defining a magnetic field between the first and second magnets; said magnetic field adapted to substantially encompass said perishable substance; anda porous material located between the first and second magnets to prevent contact between the first and second magnets.

Abstract: A tall open top plastic container has a closed bottom portion sealed to the lower end portion of a tubular water filter member having an upper end portion sealed to a removable plastic top wall within the container and sealed to the container. Flexible water inlet and outlet tubes have inner end portions connected through the top wall to an annular inlet chamber surrounding the filter member and a center outlet chamber within the filter member. A flexible vinyl coupler body receives the outer end portion of the inlet tube and forms a friction connection with a faucet aerator. In one embodiment, the upper portion of the container defines a cavity above the removable top wall, and the flexible tubes are coiled within the cavity where they are retained along with the coupler body during storage by a removable snap-on cap. The cavity may also be formed by an annular wall molded integrally with the removable top wall and covered by a removable cap.

Abstract: A method and device for enhancing the vapor sterilization of the lumen of medical instruments and like articles under reduced pressure. A vessel containing a small amount of a vaporizable liquid sterilant solution is attached to the lumen. The sterilant vaporizes and flows directly into the lumen of the article as the pressure is reduced for the sterilization cycle.

Abstract: A bottle with male threads on the outer bottom surface and a protruding surface on the base thereof; a silicon rubber layer provided with an elastic protrusion which has a slit on the top; a base casing with female threads on its inner surface and a minute vent centered thereon. The slit on the elastic protrusion remains closed in normal (non-suction) condition thereby, preventing the milk or liquid inside the bottle from dripping out. Once the bottle is inverted and the nipple is sucked, the slit opens a certain amount to let the air flow into the bottle. Thus, milk flows out of the nipple continuously during suction.
