A container-dispenser for products which are viscous fluids such as liquid soap, which allows one-handed operation to supply a controlled amount of viscous fluid in a convenient and clean way and protects the contents from exposure to air. The container body is equipped with a piston that applies constant pressure on the product within the container. By applying force on a valve from above, a passage is opened allowing the product to be dispensed through the top of the container. When the pressure on the valve is relieved, the opening is closed, preventing further dispensing of the product. Excess product is temporarily retained until needed in the "bowl" resulting from the convex shape of the top of the container.

1. A container-dispenser for containing and dispensing a viscous fluid comprising:a) a parallel-walled container body, formed with at least one wall defining a volume with an axis parallel to said at least one wall, said container body having a top edge; b) a piston configured to sealingly slide parallel to said axis within said container body; c) a dispensing head with a top surface and a dispensing hole extending from said top surface through said dispensing head, said dispensing head connected to said top edge of said container body such that said at least one wall, said piston and said dispensing head together define a storage volume for the viscous fluid, said top surface of said dispensing head being inwardly hollowed; and d) a normally-closed manually-operable valve mechanism associated with said dispensing hole so as to selectively block and unblock said dispensing hole wherein said dispensing hole is configured to dispense the viscous fluid onto said top surface for the temporary retention and storage of the viscous fluid until needed by a user.
