A discharge device is provided with a pressurized product filling and sealing the concentrate and the pressurizing agent P inside the container, and a discharge member discharging the concentrate by breaking through the pressurized product. The discharge member is provided with a valve which becomes a discharge passage of the concentrate, and a cap which covers the valve and is detachably mounted to the pressurized product. The discharge device is provided with a suppressing means (a maintaining mechanism, a movable lid, pressing to the bottom of the recessed part of the projecting part, a part releasing mechanism, a ratchet mechanism, a thin part and a plurality of coupling parts) for suppressing the leakage of the concentrate caused by removing the valve.

A valve dispenses flowable product from a container. The valve includes a mounting cup for mounting the valve on the container, a seal supported on the mounting cup, and a valve stem extending through the seal. The seal and the valve stem define a generally annular passage section of the valve passage that extends longitudinally along the valve axis radially between the valve stem and the seal. At least one of the valve stem and the seal includes a baffle extending transverse to the valve axis, the baffle defining a flow restriction along the generally annular passage section.

Provided is an injection container capable of relieving an overpressure state which includes a housing having therein an accommodation space for accommodating contents, and having an upper sealing cap for sealing an upper part of the accommodation space; a mounting cup mounted to the upper sealing cap, and having a through hole at a middle part thereof, a stem housing including a mounting portion having a hollow portion therein and mounted to the mounting cup, and a communication flow path for communicating the hollow portion with the accommodating space; a valve stem having one side which passes through the through hole, having another side arranged at the hollow portion so as to be slidable, and having an orifice selectively communicated with the hollow portion by the sliding; and a flow path blocking valve configured to block the communication flow path when an overpressure occurs.

The present invention relates to a spraying vessel and a valve assembly comprising the same, the spraying vessel comprising: a housing provided with an upper sealing cap for sealing an upper portion and a receiving space for receiving contents; a mount cup, mounted on the upper sealing cap, having a through hole formed in a central portion thereof; a stem housing provided with a mounting portion, mounted to the mount cup, having a hollow portion formed therein, and a communication flow path for making the hollow portion be in communication with the receiving space; a valve stem which is installed to pass through the through hole and slide in the hollow portion, and is provided with an orifice being configured to selectively communicate with the hollow portion by a sliding motion; and a flow path blocking valve formed to block an inlet of the communication flow path.

Provided are an aerosol container, an actuator and a protective member for the aerosol container, with high safety capable of preventing breakage of a valve mechanism when an excessive impact acts on a stem in an axial direction. The present invention provides an aerosol container in which an actuator is attached to a stem, characterized in that a safety mechanism part is provided in a part of a path through which an external force is transmitted to the stem, the safety mechanism part being configured to prevent breakage a valve mechanism of the aerosol container against an excessive external force which exceeds a force required for discharge operation of contents and which may damage the valve mechanism.

An overcap assembly configured to attach to a container. The overcap assembly includes a body, an actuator, a first nozzle, and a second nozzle. The actuator is integrally attached with the body and defines a longitudinal axis. The actuator further comprises a fluid passageway that extends therein. The first nozzle and the second nozzle extend laterally from the actuator, and the first nozzle and the second nozzle define a portion of the fluid passageway. The first nozzle comprises a first angled exit aperture and the second nozzle comprises a second angled exit aperture. The first nozzle and the second nozzle each comprises an inner cylindrical wall and an outer cylindrical wall surrounding and spaced apart from the inner cylindrical wall. The first angled exit aperture and the second angled exit aperture are non-parallel to the longitudinal axis.

A valve for dispensing a fluid from a container and a dispensing apparatus with such a valve are proposed. The valve has a spring device for returning a valve element to a closed position, the spring device being integral with the valve element. The spring device has a contact area for contact with a counterface of a valve body, the contact area forming an elevation of an outer surface of the spring device. The spring device and the counterface are in point contact with each other in any position of the valve element. The materials of the contact area and the counterface are matched to each other in such a way that they slide silently on each other. A seal of the valve is made of polyethylene or a thermoplastic elastomer. The valve is preferably designed as a full plastic valve and is easily recyclable.
