Abstract
Provided are devices, compositions, and methods for surface disinfection and decontamination; the devices generally adapted to contain a single or multi-component indicator composition, and optionally a disinfectant composition, and to dispense the indicator composition and optional disinfectant composition to a disinfectant solution, a surface, or a disinfectant article upon actuation of the device; also provided is an article of manufacture in the form of a removable cartridge adapted to fit a device described here, which may be pre-filled with a single or multi-component indicator composition as described here, and/or with a disinfectant composition, and one or more optional additives.
Core Innovation
The invention relates to a removable cartridge configured to be coupled to a device for applying a multi-component indicator composition to a disinfectant wipe dispensed through the device. The cartridge housing defines a reservoir and includes a penetrable barrier extending through a portion of the cartridge housing. The reservoir is configured as 3 chambers sized to contain separate components of the multi-component indicator composition.
In the removable cartridge, a first chamber contains a first composition comprising a colorant, a second chamber contains a second composition comprising a catalyst or hydrogen peroxide, and a third chamber contains a third composition comprising an additive and/or a further catalyst, or an alkaline base and/or a copper salt. The colorant is defined in the claims by dye classes, including triarylmethane dye, azo dye, indigoid dye, acid dye, or basic dye.
The cartridge is structured so that the separate components are contained in distinct chambers prior to application to the disinfectant wipe. The design supports keeping the different components separated within the cartridge structure through the penetrable barrier until application.
Claims Coverage
The document provides two independent claims, both directed to a removable cartridge with a three-chamber reservoir holding separate components of a multi-component indicator composition applied to a disinfectant wipe through a device. Across the independent claims, there are three inventive components: a cartridge with a housing reservoir and penetrable barrier, a three-chamber partition for separate components, and specific chemistry assignments to each chamber.
Removable cartridge with reservoir and penetrable barrier
A removable cartridge configured to be coupled to a device, comprising a cartridge housing defining a reservoir and a penetrable barrier extending through a portion of the cartridge housing.
Three-chamber partition for multi-component indicator composition components
The reservoir comprises 3 chambers sized to contain a separate component of the multi-component indicator composition.
Chambered assignments of colorant, catalyst, and additive or further catalyst
A first chamber comprises a first composition comprising a colorant, a second chamber comprises a second composition comprising a catalyst, and a third chamber comprises a third composition comprising an additive and/or a further catalyst.
Specific indicator chemistry assignment using hydrogen peroxide and alkaline base and/or copper salt
A first chamber comprises a first composition comprising a colorant selected from a triarylmethane dye, an azo dye, an indigoid dye, an acid dye or a basic dye, a second chamber comprises a second composition comprising hydrogen peroxide, and a third chamber comprises a third composition comprising an alkaline base and/or a copper salt.
The claim coverage centers on a removable, device-coupled cartridge that uses a reservoir divided into three chambers containing separate indicator components. The inventive structure assigns a colorant to the first chamber, a catalyst or hydrogen peroxide to the second chamber, and an additive/further catalyst or an alkaline base and/or copper salt to the third chamber.
