A discharge device for a liquid medium includes a storage container for receiving a medium, a discharge head which can be secured on the storage container and comprises a discharge opening for discharging the medium out of the storage container, an outlet valve which is paired with the discharge opening and comprises a pretensioned valve element that delimits a valve pre-chamber by means of a pressure application surface formed on a membrane. The pressure application surface has a stationary clamping region on the outside, and a pressure equalization channel which opens into the storage container and comprises a filter assembly that operates microbiologically and is inserted into the pressure equalization channel. The pressure equalization channel is separated from a medium path from the storage container to the discharge opening via the valve pre-chamber, and the pressure application surface has a cap-like edge protrusion as a clamping region which can be placed on a plate edge of the inner component of the discharge head on the inside. The plate edge has a stop that extends outward radially and forms a support surface for the edge protrusion while being spaced from the pressure application surface by a head surface of the plate edge.

A container lid for a fluid container of a resilient deformable material includes a body member having a drinking aperture; an actuator coupled to the body member via an area surrounding the actuator; and a valve. The lid has a first stable and a second stable state in which the area surrounding the actuator in generally inverted from the first stable state. Upon application of a first force to the top surface of the actuator when in the first stable state, the actuator temporarily deflects the valve to unseal the drinking aperture and upon removal of the first force the valve reseals the drinking aperture and both the actuator and the lid reassume the first stable state. Upon application of a second force to the actuator sufficiently greater than the first force, the lid assumes the second stable state in which the drinking aperture remains unsealed.

A dispensing closure for dispensing liquid, comprising an outer nozzle component (6) defining a nozzle opening (66) and a valve assembly (7) disposed in the closure upstream of the nozzle opening, the valve assembly comprising an outer valve element (3) and a generally rigid intermediate valve seat element (4) disposed inwardly of the outer valve element, the outer valve element comprising an outer valve flap (38) and the intermediate valve element (4) defining an outflow opening (451) bordered by an outer seat region (411, 471), the outer valve flap (38) being movable between a closed position, in which it overlaps the outer seat region of the intermediate valve element to close the outflow opening (451) against inflow therethrough, and an open position, in which it is deflected away from the outer seat region (411, 471) to open the outflow opening for outflow.

A discharge container including: a container body having an outer layer body with an outside air introduction hole and an inner layer body held inside of the outer layer body and configured to be deformable to undergo volume reduction; an inner plug having a partition wall covering an opening of a mouth and a sealing tube protruded from an undersurface of the partition wall and in abutment with an inner periphery of the mouth; a discharge cap having a discharge port from which contents are discharged and attached to the mouth to surround the inner plug from outside; and a valve body disposed between the inner plug and the discharge cap and configured to open/close an outflow hole provided in the partition wall, wherein the inner plug or the discharge cap has a deformation suppressing portion in abutment with an outer periphery of a upper end of the mouth.

The present invention is directed to a fluid transfer apparatus for sucking liquid from a container and transferring to another container or target. The fluid transfer apparatus comprising a squeeze bulb, the squeeze bulb having a first opening and an opposite second opening. A first check valve coupled to the first opening and a second check valve coupled to the second opening, wherein the first check valve and the second check valve together are configured to control the direction of fluid flow in one direction i.e. the liquid can enter from first check valve leaves from the second check valve. A transfer tube is fluidly coupled to the first check valve and a dispensing tube is coupled to the second check valve. The squeeze bulb is configured to suck liquid from a container through the transfer tube, wherein the liquid collects in the squeeze bulb and the dispensing tube. The other end of the dispensing tube is closed by a nipple, the nipple having a hole.

The lid has a first stable and a second stable state in which the area surrounding the actuator in generally inverted from the first stable state. Upon application of a first force to the top surface of the actuator when in the first stable state, the actuator temporarily deflects the valve to unseal the drinking aperture and upon removal of the first force the valve reseals the drinking aperture and both the actuator and the lid reassume the first stable state. Upon application of a second force to the actuator sufficiently greater than the first force, the lid assumes the second stable state in which the drinking aperture remains unsealed.

There are provided a check valve structure that not only prevents backflow of fluid but does not discharge fluid for unintended pressure in a correct direction, and a squeeze container using the check valve structure. A squeeze container includes a container and a nozzle member attached to an opening of the container. The nozzle member is provided with a check valve structure that is closed in an unloaded state, and that blocks a flow of fluid from downstream and allows a flow of fluid from upstream. The check valve structure is opened when an elastic valve element elastically deforms in two stages due to pressure of fluid from upstream (container).

A package that is configured to store and dispense fluids. The package includes a container and a dosing dispenser for closing an opening to the container. The dosing dispenser includes a body portion having a syringe receiver and a valve assembly that is configured to permit the flow of fluid from the container to the syringe.

A discharge container has: a container body and an inner layer body; a discharge cap; and a valve, wherein the discharge cap includes a top wall portion having the discharge port, and a cylindrical side wall portion connected to the top wall portion, and an annular second seal portion and a second engagement portion are provided at an inner peripheral surface of the side wall portion, the second seal portion abutting against a first seal portion of the mouth portion located below the outside air introduction hole on a whole circumference, and the second engagement portion undercut-engaging with a first engagement portion located at an outer peripheral surface of the mouth portion above the first seal portion.
