Filed:

Mar 28, 2000

Appl. No.:

09/537195

Inventors:

Minh Quang Hoang - Taylorsville UT
Jonathan Karl Burkholz - Salt Lake City UT
Donald Edward Hunt - Provo UT

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

B67D 558

US Classification:

222190, 222180, 2223217, 2223219, 2224641

Abstract:

A foam dispensing device is disclosed. The device includes a container for holding a foamable liquid and having at least one planar surface and a foam generating piston pump removably attached to the container to prevent liquid leaking from the container. The device can dispense foam when substantially the entire quantity of the liquid has been dispensed from the container when the container is in positioned in a first, generally horizontal position, or a second, generally vertical position.

International Classification:

C11D 162

US Classification:

510130, 510101, 510131, 510138, 510159, 510383, 510384, 510386, 510391, 510419, 424404, 424 7028, 424 7807

Abstract:

An antimicrobial composition comprising an alcohol in an amount from about 60 to about 95 weight percent of the total composition, a preservative, a cationic cellulose polymer thickening agent, a moisturizer and/or, a cationic emulsifier, and water in an amount from about 6 to about 30 weight percent. The skin disinfecting formulation will not irritate, dry or crack the skin and will provide antimicrobial effectiveness to the skin.

International Classification:

A61K007/50
C11D017/00

US Classification:

510/130000, 510/424000

Abstract:

An antimicrobial formulation is provided which comprises an antimicrobial agent and a foam boosting surfactant where the viscosity of the formulation is less than about 50 cps at 24 C. The formulation has a low viscosity and has excellent foam properties when used in a foaming dispenser. The formulation is useful in providing antimicrobial effectiveness in surgical scrub applications.

Appl. No.:

9/512402

Inventors:

Minh Quang Hoang - Taylorsville UT
Jonathan Karl Burkholz - Salt Lake City UT
Donald Edward Hunt - Provo UT

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

B67D 558

US Classification:

22218911

Abstract:

A foam dispensing apparatus of the present invention includes a reservoir containing a foamable liquid, with a closed headspace above a surface of the liquid. The apparatus also includes a source of a gas disposed to impose a gas pressure higher than ambient atmospheric pressure into the closed headspace. There is a mixing chamber having an inside diameter, an inlet and an outlet open to the ambient atmosphere with a flow restricter having a plurality of openings therein in gaseous communication with the closed headspace. The foam dispensing apparatus also includes a hydrophobic filter.

Abstract:

A foam dispensing apparatus of the present invention includes a reservoir containing a foamable liquid, with a closed headspace above a surface of the liquid. The apparatus also includes a source of a gas disposed to impose a gas pressure higher than ambient atmospheric pressure into the closed headspace. There is a mixing chamber having an inside diameter, an inlet and an outlet open to the ambient atmosphere with a flow restricter having a plurality of openings therein in gaseous communication with the closed headspace. The flow restricter is positioned at the inlet of the mixing chamber and an elongate delivery tube with an open passageway therethrough that defines a longitudinal axis extending from the inlet of the mixing chamber to below the surface of the foamable liquid disposed so that an application of the gas having higher pressure than atmospheric pressure to the headspace causes the foamable liquid to flow through the tube past the flow restricter, to mix with the headspace gas having higher pressure than atmospheric pressure that flows from the openings in the flow restricter and then to expand to atmospheric pressure in the mixing chamber thereby to form a foam from the foamable liquid and discharge the foam from the outlet.
