Abstract: A vent valve, and a vent valve assembly, for a liquid dispensing container, employ a vent disc having small open vent holes in cooperation with an overlying thin flexible flap that covers and closes the vent holes to limit liquid pressure on the holes when the container is upright, yet require little suction pressure to move the flap to draw liquid or vent through the holes. The vent valve can be used in a bottom cap that is attachable to the bottom open end of the container. The vent valve assembly includes such a bottom cap, a sealing member for sealing the bottom cap to the container, and a vent valve. The vent valve and/or bottom cap have an elevated vent disc and a top portion having the thin flexible flap.

Abstract: The invention is a vent for use with a container, such as commercial steel pails and drums, and a method for venting containers. The vent has a cap seal with one or more semipermeable membranes covering an orifice in the cap seal. The membrane prevents the passage of at least one atmospheric component, but allows the free passage of air. When a product is filled into the container at an elevated temperature and cools, a vacuum is formed within the container. The resulting vacuum opens a vacuum release device in the vent and pulls air through a hole in the cap seal, which is protected by a micro-porous membrane. The venting of air into the container relieves the vacuum without damage to the container or the product within the container.

Abstract: A bottle adapter is disclosed for accurate squirt dispensing of a drink. The bottle adapter comprises a coupler for removable attachment to a squeezable bottle. The coupler has a valve that is configured to remain closed until a predefined pressure difference is present across the valve, so that when the valve is opened, the liquid inside the container emerges in a stream and maintains a substantially straight trajectory for at least a predefined distance. A targeting orifice is positioned at the predefined distance from the valve so that the stream trajectory extends through the targeting orifice.

The packaging material uses a film in which a heat sealing agent (4) with a low melting point is applied to a prescribed zone of an oriented film (2) made of a synthetic resin, a cutting line (5) is cut in the oriented film (2) made of a synthetic resin in the form of a solid or broken line passing through the zone coated with the heat sealing agent (4), and a cast film (3) made of a synthetic resin and having heat sealing properties is affixed to the oriented film (2) made of a synthetic resin. Such film is used for a packaging bag (1) or a container cover.

Abstract: The invention includes aseptic packages and methods and systems allowing aseptic filling on a conventional filling line, with relatively small and inexpensive equipment modifications. The invention allows avoidance of the conventional need to encase all or part of the filling equipment in a sterile air atmosphere. The invention includes a package, fitted with a flexible membrane, which can trap and carry its own sterility through the filling steps, whereby the membrane finally becomes part of the cap of the package. The invention reduces product risk, operator specialisation and the costs of aseptic filling.

Abstract: A cap with a way-one valve solves two distinct problems in the field of packaging materials that emit gasses, providing both a means to prevent a package from deforming under pressure built up inside the package, and a means to reseal the package. The cap comprises an inner wall extending downwardly from an inner portion of the top wall to define a cavity. An insert valve is mounted within the cavity, forming a seal with the inside wall. The upper surface of the insert valve, inner wall, and the top wall define a chamber with a gas escape path. A septum is disposed within the chamber, the septum seated on the insert valve and sealing one or more apertures in the insert valve. The septum is capable of at least partially unseating in response to force exerted by increased gas pressure acting through the apertures.

Abstract: The present invention is an improved reservoir cap for a braking fluid reservoir including a cylindrical skirt for surrounding an opening of the reservoir body, a disc portion having a hard stop formed unitarily with the cylindrical skirt for closing the reservoir fill opening, and a plurality of teeth formed unitarily about the hard stop for securing an elastic member. The elastic member is disposed about the teeth of the reservoir cap and secured thereto. The elastic member defines ridges disposed circumferentially about its center. Between the ridges and the center of the elastic member is a channel, which in turn defines a pair of openings which permit the flow of excess fluid through the elastic member, thereby reducing the possibility of fluid overflow, and thus preventing excess brake fluid from permeating the reservoir cap and leaking into the engine compartment of a vehicle.

Abstract: The package is closed by a lid and it is fitted with a valve fixed over an opening zone of section greater than 10 mm2, and preferably lying in the range 30 mm2 to 50 mm2, leading to the inside of the package and formed through said lid. This opening zone is either an orifice formed through a flat lid, or else a hollow chamber itself pierced by a vent orifice of small size. The valve comprises solely a flexible sheet extending over the opening zone together with a sealing compound disposed between the flexible sheet and the lid. The sealing compound is solid at ambient temperature and it passes to a non-sticky liquid state when its temperature is raised. During heat treatment, the valve opens and closes in a succession of venting sequences.
