Manual Spray Cleaner

Abstract

A cleaning solution package comprising a dispensing container having a body with a closed bottom and an open upper end forming a neck and a dispensing valve mounted in the neck. A flexible pouch is mounted within the container and has an open upper end that is sealed to the dispensing valve. A cleaning composition containing an oxidizing agent is stored in the flexible pouch. A pressurized gas is between the container body and the flexible pouch to pressurize the cleaning solution within the flexible pouch.

Benefits of technology

[0014]According to another embodiment, the cleaning solution package can be free of volatile organic compounds. The cleaning solution package can further comprise citric acid in an effective amount to act as a chelating agent and an oxidizing agent stabilizer.

Problems solved by technology

Soft household surfaces such as carpets, rugs, upholstery and fabric are often subject to contact with compositions, such as spills, which can cause a stain on the surface.

Many users prefer manually applicable cleaning compositions since they can be quickly applied to a stain without needing a cleaning appliance, many of which are expensive and cumbersome to use.

However, the use of hydrogen peroxide creates challenges with respect to maximizing the shelf life of such cleaning compositions, while minimizing the effects of the inherent reactive nature of the chemical.

The ability to formulate an “all-in-one” cleaning composition, i.e. a cleaning composition that includes both cleaning agents and hydrogen peroxide in a single formulation, that can be packaged within a single container presents many technical challenges, primarily related to: (1) the chemical resistance of the container to the hydrogen peroxide containing formula; (2) the chemical compatibility of the various ingredients present in the cleaning composition; (3) the shelf life of the active ingredients present in the cleaning composition; and (4) the potential premature activation of hydrogen peroxide present in the cleaning composition.
