Abstract: A fluid storage container includes a container body provided with an interior space for storing a fluid and an opening for guiding the fluid from the interior space to the outside. A lid covers the opening of the container and is provided with a discharge opening for the fluid. The discharge opening is configured so that the discharge opening is normally in a closed state, sealed by a plug, but is set to an open state when extracting the fluid from the container body. Thus, outside air and impurities are prevented from entering the container, which prevents the degradation of the contents of the container and thereby drastically increases the lifespan of the contents.

Abstract: A content discharge mechanism for a container with a pump has a discharge outlet that is fixed in position. The device has an operation button and a cylindrical piston that move as one, as well as a ball valve that rests on a seat. The ball valve opens as the cylindrical piston retracts after an actuation to allow more fluid into the upstream passage chamber. A downstream passage with a valve for dispensation fluidly communicates with the upstream passage through a hole. As the cylindrical piston and its seal slide over the hole, the discharge from the downstream passage stops.

Abstract: By means of a fluid material discharge device of simple construction, a technique for fluid material discharge is provided which has few or no inadequate discharge, high productivity, and which enables easy modification and adjustment of the amount of fluid material discharge. The fluid material discharge device comprises a nozzle for discharge of fluid material and a filament-shape member inserted into the nozzle for use. The filament-shape member has a tip portion AA, which is exposed outside of the nozzle when no pressure is exerted on the tip of the filament-shape member, a portion BB which can be inserted into the nozzle, and a portion CC, on the side of the filament-shape member opposite the tip portion AA, and being bent from the portion BB. The spring structure of the filament-shape member is utilized to discharge fluid material.

Abstract: A droplet ejection apparatus has an ejection unit that ejects a droplet of liquid onto a target. The ejection unit is arranged in a multi-joint robot. The robot moves the ejection unit in a two-dimensional direction above the target. The ejection unit includes a droplet ejection head, a liquid tank, and an auto-seal valve. The auto-seal valve adjusts the pressure of the liquid supplied from the liquid tank to the droplet ejection head to a predetermined pressure. The auto-seal valve has a valve body that is movable between a closing position and an opening position in correspondence with the difference between the pressure of the liquid in the droplet ejection head and the pressure of the liquid in the liquid tank. The valve body is arranged such that the direction of acceleration that produces force capable of moving the valve body from the closing position to the opening position differs from the direction of acceleration of the ejection unit moving in the two-dimensional direction.

Abstract: A one-way valve device comprises a valve seat arranged in the neck of a container that extends transversely across the interior of the neck and defines a plurality of passage openings. A pin-like projection is formed on the valve seat and extends axially to the exit opening. An elastic seal is held on the valve seat and comprises a sleeve-like section which surrounds the projection of the valve seat with the exception of its end section which rests on the end section of the projection. Applying pressure to the contents of the container axially displaces the sleeve-like part of the seal relative to the pin-like projection, so that the contents of the container can exit. In the closed position, an annular projection of an outer cap firmly presses the sleeve-like section of the seal against the projection of the valve seat, so that no container contents can exit.

Abstract: A valve (1), particularly for an aerosol container, includes, inside a valve body (2), an inlet passage (4) communicating with the container and an outlet passage (10), a first elastic return (16) for urging the valve (1) into the closed position, and a regulator for regulating the product outlet flow rate, which includes a second elastic return (14) for supplying a set-point pressure for the regulator. The second elastic return (14) is arranged in a compartment (12) of the valve body (2) isolated from the product, the pressure inside the compartment (12) being equal to atmospheric pressure.

Abstract: A dispensing package is provided for fluid products such as liquid soaps, shampoos and conditioners, household detergents, cleaners, polishes, moisturizing creams, and the like, and includes a container with a self-sealing dispensing valve mounted therein. The valve includes a marginal flange, a valve head with a discharge orifice therein, and a connector sleeve having one end connected with the valve flange and the opposite end connected with the valve head adjacent a marginal edge thereof. The connector sleeve has a resiliently flexible construction, such that when pressure within the container raises above a predetermined amount, the valve head shifts outwardly in a manner which causes the connector sleeve to double over and extend rollingly.

Abstract: An apparatus for filling a specified amount of liquid comprises a vertical tubular nozzle having a large-diameter portion intermediately of its height and a valve seat at the edge of an open lower end thereof, a valve upwardly and downwardly movably supported by the filling nozzle and comprising a plug intimately fittable to the valve seat and a stem extending upward from the plug inside the nozzle, a resistance member fixed to the valve stem so as to be positioned in the large-diameter portion for acting against a downward flow of liquid, a spring biasing the valve upward to hold the plug in intimate contact with the valve seat against the gravity on the liquid within the nozzle, a metering cylinder for intermittently feeding the liquid into the nozzle in the specified amount at a time so that the valve is opened by the pressure of flow of the liquid against the spring, and the spring closing the valve when the feed of liquid is discontinued.

Abstract: A dispensing device for a squeeze bottle has an internal continuously circular vent valve seat. A continuously circular elastic vent valve has one side seating on the seat and an opposite side exposed to the inside of the device. The device has a self-closing dispensing valve which opens upon squeezing the bottle. The device has a lock to prevent unintentional opening of the dispensing valve.

Abstract: An automatic closure device for containers being openable by pressure on the container and closable when such pressure is released. A cap member having a discharge orifice adapted to be closed by a plug member on a hollow stem is provided. The hollow stem has a discharge port. A diaphragm is positioned on said stem extending out to said cap, and a seal member having an aperture defined therein for receipt of said stem is positioned within said cap forming a pressure chamber between it and the diaphragm. Above the diaphragm which is resilient and movable downwardly by pressure is a discharge chamber. A lock is provided to also lock the plug in an open or in a closed mode.

Abstract: A safety container for dispensing highly flammable liquids is described, which comprises flexible compressible container walls and a safety valve which is designed as a membrane-controlled cone valve, closable by a cap. The membrane exhibits a central hole bounded by a sealing edge, through which a valve cone is inserted and contacted by the sealing edge. The cone valve is operated by pressing the flexible container walls together and thereby reducing the interior space of the container and raising the internal pressure.

Abstract: In a device for the melting and measured discharge of a thermoplastic adhesive, the adhesive material is melted within a melting chamber and then flows out through a discharge nozzle. The discharge nozzle contains a spring biased valve body for blocking flow out of the melting chamber until the biasing force is overcome. If the spring fails and cannot return the valve body into position to seal the melting chamber, the discharge nozzle is arranged to prevent the valve body from blocking the flow of the melted adhesive material through and out of the discharge nozzle.

Abstract: A fluid pump dispenser includes a dispenser trigger which may be located in pivotable engagement with the dispenser housing and pump piston after shipment. The initial actuation of the trigger moves the pump piston and a container conduit, engaged thereto, to open a container vent shipping seal provided by mating surfaces on the conduit and the container cap. Fluid carried from the container by the conduit enters the pump chamber through a central orifice in the piston. A flexible member located on the piston functions as an inlet check valve for the conduit and as a piston ring. The fluid dispenser also includes a nozzle structure having a flexible member which functions as an outlet check valve and O-ring seal, and which cooperates with a threaded nozzle cap to vary the discharge pattern of the dispenser responsive to twisting adjustment of the cap.
