Spray can actuator
U.S. Patent No. 10,464,736
The B’Laster Corp.
The B’Laster Corp., Valley View, OH, patented an
actuator for a spray can. It includes housing for attachment
to an aerosol can covering a stem valve. A
finger-operating button structure is engaged with the
housing to engage the stem valve. A rotary two-way
diverter valve is supported within the housing
and rotatably engaged with the finger-operating
button structure. In a spray position (straw down),
the two-way diverter valve directs spray through a
first direct spray nozzle. In a second spray position
(straw up), to make use of an adjustable straw, the
diverter valve is rotated to engage a straw spray passage
of the diverter valve in fluid communication with an adjustable
rotary spray tip and engaged straw. By rotating
the adjustable rotary spray tip to an aligned position,
the tip substantially blocks the straw spray passage to
provide a drip mode, where drops of fluid exit the straw.
A flexible tip may optionally be provided on the straw
to enable bending and retention of the flexible tip to a
desired position.
De-icing lubricant composition
U.S. Patent No. 10,428,290
Falconer, Dustin
Dustin Falconer, Grande Prairie, CA, patented a de-icing lubricant composition including isopropyl alcohol and mineral oil.
The isopropyl alcohol may be 60–90% of the composition by weight. The mineral oil may be 10–30% of the composition by
weight. The composition may include a dye and/or a propellant. The propellant may be CO2. A method of restoring mobility
to frozen components is also provided by applying a composition as described above to a frozen component. The de-icing
composition may be placed in an aerosol can or in a manual pump spray apparatus.
Hair color compositions & methods
U.S. Patent No. 10,398,635
L’Oréal Paris
L’Oréal Paris, Paris, France, patented hair coloring agents, compositions and methods to improve the quality and durability
of color in artificially-colored hair. The compositions employ divalent metal salts of inorganic acids, monovalent or divalent
metal salts of organic acids, antioxidants and colorants. Methods are described wherein hair is contacted with the compositions
of the present disclosure, resulting in improved artificial color deposition, as well as improved quality and durability of
the color in artificially-colored hair.
When the formulation is dispensed from a pressurized aerosol container, a propellant may be used to force the composition
out of the container. Suitable propellants include, but are not limited to, a liquefiable gas or a halogenated propellant.
Examples of suitable propellants include dimethyl ether and hydrocarbon propellants such as propane, n-butane, iso-butane,
chlorofluorocarbons (CFCs) and CFC-replacement propellants. The propellants may be used singly or admixed. The amount
of propellant may range from about 10%–60% by weight of the formulation. The propellant may be separated from the hair
color formulation, as in a two-compartment container. Other suitable aerosol dispensers are those characterized by the propellant
being compressed air, which can be filled into the dispenser using a pump or equivalent device prior to use. Conventional
non-aerosol pump spray dispensers, i.e., atomizers, may also be used to apply the formulation to the hair.
