The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed cannister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

The present disclosure relate to an actuator assembly for an aerosol can. The assembly includes a body attachable to a can and a disc provided with two opposing levers. The disc is hinged to the body and generally overlies a valve provided on the aerosol can. When either lever is depressed, a valve socket on the bottom of the disc engages the valve of the aerosol can to discharge pressurized liquid through a port formed through the disc. One of the levers is provided with a catching member that engages and selectively locks onto a latch provided on the body so that the lever is captured in a depressed position to cause the continuous discharge of liquid from the can. The captured lever can be released to discontinue discharge of liquid by pressing the other lever.

An aerosolized disinfectant assembly for automatically disinfecting a room with an aerosolized disinfectant includes an aerosol that includes a chemical disinfectant. A canister is provided and the aerosol is contained under pressure within the canister. A fogger is coupled to the canister and the fogger is in fluid communication with an interior of the canister. The fogger is positionable in an open position thereby facilitating the aerosol to be released from the canister and into the room. In this way the chemical disinfectant is distributed around the room to disinfect the room.

A dispensing device for attaching to a container having a valve stem includes: (a) a hollow tube having a flow channel defined by a wall extending between entrance and exit ends with a connector on the entrance end for connecting to the valve stem; (b) a sleeve extending slidably over a portion of the hollow tube, the sleeve extending over, and having an opening proximate to, the hollow tube's exit end; (c) a sealing gasket around the outside of the hollow tube and between the hollow tube and the sleeve that prevents fluid communication past the gasket between the hollow tube and sleeve; (d) a trigger mount rigidly attached to the hollow tube or container; (e) a trigger hingedly connected at a first location to the trigger mount and operatively engaged with the sleeve at a second location; and (f) an elastic element between the trigger and the hollow tube and/or container.

A cartridge usable in a viscous-material dispenser includes a cylinder, a plunger in the cylinder, and a plurality of ribs extending radially from an outer surface of the plunger to an inner surface of the cylinder. The ribs are circumferentially separated by a plurality of clearances, and the ribs and the clearances extend in an axial direction. Each of the plurality of clearances is defined by two adjacent ribs. The ribs and clearances are configured to allow the venting of gas through the clearances during a beginning of a cartridge filling operation and to impede the movement of the viscous material through the clearances during a remainder of the cartridge filling operation such that, at an end of the cartridge filling operation, the ribs and bodies of the viscous material in the clearances form an airtight seal between the plunger and the cylinder.

A dispensing device that attaches to a container has: (a) a hollow tube with opposing entrance and exit ends with a connector on the entrance end and a wall defining a flow channel; (b) a sleeve with opposing entrance and exit ends slidably extending over the hollow tube; (c) a sealing gasket between and contacting the hollow tube and sleeve; (d) a trigger mount rigidly attached to the hollow tube or container; (e) a trigger hingedly connected to the trigger mount and operatively connected to the sleeve; (f) an elastic element between the trigger and the hollow tube and/or container; wherein the exit end is closed and there is an opening through the hollow tube wall proximate to the exit end; the sleeve has an open dispensing end, reduces in inside diameter at dispensing end and engages the hollow tube when closed and disengages from the hollow tube when open.

The present disclosure relates to an aerosol container made of plastic, the container having a neck, the opening of which is closeable in a pressure-tight manner by a valve unit that can be actuated by a pushbutton, the container being Tillable with a liquid or gaseous propellant and a liquid to be sprayed. The aerosol container can be an injection cast preform with an elongated tubular preform body. The preform body is closed by a dome-shaped convex preform base, beyond which an integrally formed stand region projects in an axial direction. The preform body adjoins the opening of the neck at the opposite axial longitudinal ends of the preform body.

The invention pertains generally to an improved fluid dispensing device, particularly a dispensing device which employs at least one hemispherical domed canister source of reactants and which uses a color-changing dispensing plastic tip to inform the end-user if the reactants are at a proper use temperature.

An aerosol dispenser, an outer container for an aerosol dispenser and a preform for an outer container. The aerosol dispenser, outer container and preform each have a neck, which in turn has a crimp ring, to receive a valve cup clinched thereto. The crimp ring has slots which act as vents therethrough. The vents may be exposed to pressurized propellant and product due to deformation of the neck during undue internal pressurization. The cross section of the vents diverge in the downward direction to provide both flow area and for product and propellant and adequate area for the valve cup to be corrugatedly clinched to the crimp ring.

A sparkling wine sprayer configured to spray a sparkling wine for recreational activities includes a bottle top sealing system pivotally and operatively coupled to a quick release lever to provide an airtight seal to a sparkling wine bottle. The bottle top sealing system is further connected to a tube that carries a sparkling wine through the sprayer. To use the sprayer, a top of the bottle is sealed by pulling the lever towards a user, attaching a top of the bottle to the bottle top sealing system and then pushing the lever back. The trigger is then pressed to that opens a valve in the tube and aligns the tube sections, allowing the sparkling wine to flow through the tube and spraying the sparkling wine through the nozzle. On the other hand, depressing the trigger stops spraying of the sparkling wine.
