摘要:
An actuator for a spray valve is provided which includes an actuator head and spray producing body positioned within the head. The actuator head includes a mechanism for connecting the head to a spray valve and transfer channel for receiving a pressurized fluid from the spray valve. The transfer channel is formed with a terminal area surrounding an outlet orifice of the channel. The spray producing body is positioned against the terminal area and has a front wall distant therefrom. The spray producing body features a swirl chamber situated adjacent the outlet orifice, a first channel downstream from the swirl chamber, a second channel of narrower diameter and downstream from the first channel, an expansion orifice situated further downstream and at least four unconnected dead-ended recesses formed into the front wall and surrounding the expansion orifice.

An overcap sprayer assembly and method of its manufacture. The overcap sprayer assembly includes an actuator and an overcap. The actuator has a body and a sprayer arm. The body attaches preferably to the valve cup rim of the can. A skirt extends circumferentially around the perimeter of the body. At least one actuator access port provides access through the skirt to the interior of the body. The sprayer arm of the actuator has a nozzle adapted to direct spray outwardly through an actuator access port. The overcap attaches to the skirt of the actuator body in coaxially turning relation thereto. An overcap wall extends downwardly from the outer margins of the overcap dome, surrounding the actuator body. The overcap also has at least one overcap access port that may be moved between an open position, wherein an overcap access port is aligned with the actuator access port through which the nozzle is adapted to direct spray, and a closed position, wherein the overcap wall obstructs the actuator access port. Preferably a lock member extends from one of the actuator body and the overcap to project into and engage an opposed locking port of the other of the actuator body and overcap. Preferably the locking port is an access port. The lock member has an unlocked position, wherein it is not engaged in an opposed locking port and the overcap may freely turn on the actuator body, and a locked position assumed when the lock member becomes aligned with an opposed locking port, projects thereinto, and engages the opposed locking port, resisting further overcap turning.

A door actuated device for dispensing fluid from a container which comprises a holder having a plunger assembly adapted to receive a container. The container has a dispensing valve and contains a deodorizing fluid, a disinfectant or a perfumed liquid which is dispensed from the device into a room when the dispensing valve is actuated by the plunger assembly of the holder upon opening or closing of a door.

In a whipped cream dispenser incorporating a tilt-type aerosol valve the tubular actuator has at its base a downwardly facing annular shoulder. This shoulder, by butting against the metal of the valve pedestal, prevents further tilting and further stress on the tubular valve spout. Further, ribs on the stem and actuator keep the actuator in fully installed position on the valve stem.

An actuator for a personal protective spray canister having a container for holding a pressurized protective material capable of being propelled in a gaseous cloud to at least partially disable a person and a manipulative valving device protruding outwardly from the container, with the valving device having an outlet for directing the gaseous cloud from the container, and a valve element movable between a first biased normal position closing the outlet and a second depressed operative position opening the outlet to allow the material to be propelled from the container as a cloud. The actuator comprising: a radio frequency receiver for detecting and receiving a coded radio frequency signal, a decoder for creating an identification signal when the receiver receives a radio frequency signal with a preselected code, a mechanical device for moving the valve element into the second depressed, operative position in response to a danger signal, a circuit for creating a danger signal in response to a given number of identification signals, a power supply for providing power to operate the mechanical device to depress the valve element when the actuator is operatively associated with the valve element of the container.

A quick cooling spray wherein a plastic nozzle body in the form of a bottomed cap-shaped has a ceiling plate held in a cantilever manner and a connection portion formed on a bottom surface of the ceiling plate, the connection portion being connected to a stem projecting from a valve housing of a container body, and a plastic nozzle body having an injection nozzle on an outer peripheral wall of the plastic nozzle body being fitted on an upper portion of said container body, further an extension tube connected to the injection nozzle being made of metal and an electrically conductive part which a finger of the operator touches being formed on the plastic nozzle body, and the electrically conductive part and the extension tube being electrically connected to each other.
摘要:
The device dispenses a dose of material, such as a perfume or deodorant, automatically on closing a door. A storage container for the material connects with a dosing compartment and an actuator releases the contents of the dosing compartment to the surroundings. A valve allows communication between the dosing compartment and the surroundings and is actuated by a holder for the container which is adapted to be fixed to the door or a jamb thereof. The holder has an arm extending radially and being hinged biasedly at a median point. A furthermost portion of the arm is adapted to contact the container or the valve to actuate the valve when the hinged portion of the arm is compressed by a gap between the door and the jamb thereof.

A method and apparatus for applying colored foam markers to road surfaces as a means of temporarily changing or outlining traffic patterns. In the preferred embodiment, dissoluble foam markers would be periodically deposited upon the road behind a work crew to alert motorists of a potential hazard ahead, in order to avoid any collisions between the motorist and the work crew. As the work crew would move up on the road, the foam markers would naturally dissipate and substantially disappear over a predetermined or a relatively short period of time so that the roadway automatically returned to its original traffic pattern when the work crew has left the area. Foam markers according to the present invention would enhance the safety of a work crew's operations and increase work output by freeing the work crew from the obligation of retrieving the markers after they are used.
摘要:
The actuating device (1) is adapted to be incorporated into a dispenser provided with a valve (41) having a tubular end (43) which must be pressed in order to discharge the product. The device (1) includes a poppet valve (10), the movement of which is substantially transverse to the axis of the end (43). Action by the user on the push-button results, on the one hand, in opening of the poppet valve (10) and, on the other hand, in pressure being exerted on the tubular end (43) by the use of a film hinge (39). The vertical movement of the push-button is converted into a horizontal movement of the popper valve by means of an orthogonal joint. The product to be dispensed still pass into a chamber rendered airtight by the poppet valve (10) and a flexible collar (13), so that the product, especially a self-foaming product, remains hermetically sealed in the chamber during periods of non-use.
