Fluid substance container
& transport system
U.S. Patent No. 10,472,152
Coster Tecnologie Speciali S.P.A.
Coster Tecnologie Speciali S.P.A., Calceranica al
Lago, Italy, patented a fluid container in the form
of a can having a neck defining an opening. Fastened
in a water-tight manner to the neck is a valve element
with a valve cup supporting a hollow stem movable
against an elastic element between a first stable closing
position and a second, unstable position. This is for
delivering fluid through a cavity in the stem; the cavity
communicates with the interior of the can in a dispensing
position. The can is fixed to a support base of the
container, the base comprising a support surface with a
recess defined by a first centering surface to center the
container on a valve cup of an identical container, on
top of which the container may be placed, a second support
surface for supporting the container on the valve
cup, and a third recessed surface to house the stem of
an aerosol valve of the further container.
Low flammability solvent composition
U.S. Patent No. 10,273,437
Illinois Tool Works Inc.
Illinois Tool Works Inc., Glenview, IL, patented a solvent composition that includes a chlorinated ethylene present
from 75%–80% total weight and at least one halocarbon miscible with the chlorinated ethylene and present in
an amount to define a weight ratio of the chlorinated ethylene to at least one halocarbon from 75:25–80:20. The
solvent composition has a flash point of less than 23°C and an initial boiling point of greater than 35°C. When
the solvent is packaged as an aerosol with a propellant, the resulting solvent can be used as a degreaser in confined
spaces owing to reduced ignitibility and better human health and environmental properties.
Cleaning composition
U.S. Patent No. 10,435,650
Milliken & Co.
Milliken & Co., Spartansburg, SC, patented a cleaning composition that comprises at least one surfactant and
at least one colorant. The cleaning composition can have a pH of about 3.0 or less. The colorant exhibits one of
several specified structures at a pH of about 7.0. A method for cleaning a surface utilizes the cleaning composition.
The cleaning composition may be formulated so that it may be useful in conjunction with an “aerosol”-type
product, wherein it is discharged from a pressurized aerosol container. If the cleaning composition is useful in an
aerosol-type product, it is preferred that corrosion resistant aerosol containers—such as coated or lined—are used.
Such are preferred as they are known to be resistant to the effects of acidic formulations.
