Definitions
- This invention relates to an overcap assembly of the type primarily used in conjunction with an aerosol dispenser and more particularly to an overcap for continuously dis ⁇ pensing the product of the aerosol dispenser.
- valve assemblies are of the continuous type which are primarily designed to remain in an "open” or “On” position once actuated by an operator.
- room deodorants and bug sprays and the like use continuous valve assemblies.
- One prior art continuous spray assembly has an extra- long, closed end valve stem having scored or crimped in ⁇ dentations therein. To actuate the valve, the stem is bent back and forth at the scored indentation until the stem severs to allow the product and propellant to escape.
- the major disadvantage of this type of continuous spray assembly is the inability to terminate or turn “Off” the spray once the stem has been severed. This valve can be particularly hazardous if the stem is accidentally severed during ship ⁇ ment or storage.
- Another disadvantage is the inability of the severed stem to create a desired spray pattern. The product and propellant just haphazardly spews out of the stem.
- Another type of continuous spray button assembly consists of a clip which holds the stem of a tilt valve in a tilted position.
- the clip is placed over the button and engages a rim of the aerosol dispenser.
- a hole within the clip allows the product and propellant to be dispensed from the terminal orifice of the button.
- the clip cannot be easily dislodged from the rim after actuation of the continuous spray assembly.
- a further disadvantage of this structure is the use of two separate pieces of the structure. The clip is usually just loosely contained within an overcap of the aerosol dispenser raising the possibility that the clip will be lost, especially when displayed and subjected to customer handling.
- Another type of continuous spray assembly consists of a button mounted upon a tilt valve type assembly.
- the stem of the assembly has an integral protruding arm with a hooked portion at an outer end.
- An upstanding tab which is integrally molded onto the protruding arm may be pressed to disengage the hook portion of the protruding arm, thereby releasing the button.
- the buirton then returns to the original vertical "Off" position.
- Another type of continuous spray assembly is an actua ⁇ tion cap shown in U. S. Patent 3,765,573.
- the actuation cap comprises a cylindrical sidewall with a transverse wall extending therebetween.
- the transverse wall includes a conical protuberance having a vertical axis offset from the vertical axis of the valve stem.
- the actuation cap is inverted and reseated on the rim of the mounting cup causing the protruberance to actuate the valve stem by tilting the valve into an "On" position.
- the product and propellant are then dispensed through an opening in the apex of the pro- tuberance.
- the major disadvantage of this type of con ⁇ tinuous spray assembly is the configuration of the pro ⁇ tuberance.
- the valve stem does not fit into the protuber ⁇ ance, but is only tilted by the protuberance.
- Another object of this invention is to produce a continuous spray overcap assembly which may be easily turned “On” and "Off”. Another object of this invention is to provide a means to prevent leakage of the product before the product issues from the terminal orifice.
- Still another object of this invention is to provide a structure which may utilize various swirl chambers, ex- pansion chambers, inserts and terminal orifices to achieve a desired spray pattern.
- a " further object of this invention is to provide a structure which may be used with a large variety of existing aerosol dispensers.
- a still further object of this invention is to provide a structure which is easy and economical to manufacture.
- the invention relates to a con * tinuous spray overcap assembly of the type primarily used with aerosol dispensers or cans.
- the invention functions as a standard protective overcap for the aerosol can during shipment and shelf storage.
- a valve assembly in the aerosol container includes a projecting valve stem.
- the overcap assembly may be removed and remounted in an inverted position onto a rim on the top of the aerosol can. In the inverted position, the overcap moves the valve stem into an "On" position, thereby dispensing the product and propellant. Removal of the overcap assembly causes the stem to return to the original "Off" position.
- the overcap assembly can then be reinverted and fitted onto the rim of the can of the aerosol dispenser for further shelf storage. It should be evident that all or only a portion of the product and propellant may be dispense from this continuous spray overcap.
- the overcap assembly has a cup-shape.
- a valve actuation means is disposed in the base of the cup-shaped cavity.
- the rim of the cavity is configured to be resiliently mounted onto a rim of the aerosol dispenser, such as the mounting cup rim, a rim on the chime or the outer rim of the aerosol can.
- An inside rim of the mounting cup or an undercut on the chime as well as an inside rim of the can may also be used for mounting.
- a plurality of lugs or a mere annular " lip may be utilized to hold the overcap assembly in an inverted valve actuating mounted position.
- the valve actuation means comprises a nipple for receiving the stem of the aerosol valve. As the inverted overcap assembly is mounted, the valve stem is simultaneously depressed to actuate the valve to spray product and propellant through a hole in the nipple.
- the valve actuation means has the nipple structure of the first embodiment with a terminal orifice insert fitted into a recess of the nipple. Any type of insert may be utilized depending on the desired spray pattern.
- the valve actuation means comprises an aperture which encircles the valve button of the aerosol valve.
- the button may be ridigly press-fitted onto the valve stem or may be an integral valve button with depending stem.
- the lower portion of the button has an outer annular step.
- valve actuation means has a hollow cage with a top whereby a standard valve button may be received within the cage. The top of the cage depresses the button, thereby actuating the valve.
- the cage may be simply one or more up- standing arms.
- the hand of the arm depresses the button as the overcap is mounted in the inverted position.
- a desir ⁇ able feature of this embodiment is that the arm may be made to flex outwardly to accommodate various diameters of buttons.
- Ajnajor feature of this invention is the ability to turn the spray "On" and "Off" at leisure. In many appli ⁇ cations, this feature is most desirable. For example, when a large portion of product must be dispensed, it may be desirable to spray for a rather lengthy period. Ordinarily, the user would be fatigued by the continued depression of the button. For example, bug defoggers, household deodorants, paint sprayers or rug cleaners frequently require such lengthy spray application. Bug fumigators generally require a totally continuous spray until complete exhaustion of the product and the propellant.
- Another feature of this invention is the elimination of buildup of product as it issues from the terminal orifice.
- the cavity of the nipple is specially con- figured to graspingly receive the valve stem. This pre ⁇ cludes leakage of product before the product issues from the nipple.
- the continued use of a valve button in the third and fourth embodiments inherently precludes leakage.
- valve actuation means may include various swirl chambers or expansion chambers prior to the terminal orifice.
- various type spray patterns may be achived.
- inserts such as mechanical breakup (MBU) inserts may be used to mechanically atomize the product before dispensing.
- MBU mechanical breakup
