A non-dissolvable immersible dispensing puck in the shape of a dissolvable halogen puck when the dissolvable halogen puck is in an undissolved state with the non-dissolvable immersible dispensing puck physically interchangeable with a dissolvable halogen puck when placed in a dispenser for normally holding only a set of halogen pucks to enable a single dispersant dispenser to be converted to a dual dispersant dispenser without changing the structure of the single dispersant dispenser by placing a dispenser within a dispenser wherein only one of the dispensers may be provided with adjustable water ports.

A dispenser system for delivering various combinations of dispersants to a body of water with the various combinations of dispersants supplied to the body of water through the interchanging of dispensing cartridges which are attachable to a main dispensing cartridge where a condition for interchanging of dispensing cartridges may be triggered by an event.

A mixing apparatus is for selective mixing of contents. The mixing apparatus has a body that defines an interior space. The body further has an aperture for permitting access to the interior space. The body has at least a portion that is collapsible and configured to be gripped and repositioned by a user to collapse a part of the body into the interior space to alter at least one of: the volume of the interior space; and the shape of the interior space. The mixing apparatus further has at least one mixing member located within the interior space that is configured and located so that the contents is forced against the at least one mixing member when the collapsible portion is gripped and repositioned by a user.

The invention relates to a metering device (D) for metering a reagent by dissolution in a liquid flow, characterized in that it comprises a plurality of parts: a fixed base (200) grouping together said enclosure and a liquid inlet, means for bringing the liquid into contact with the reagent roller (G) and liquid outlet means, one or more cartridges (300) forming a separate detachable volume grouping together said reagent magazine, means for forming at least one liquid jet directed substantially radially towards the roller (G) to be dissolved, and means for supporting the roller (G), said cartridge (300) coming to be associated with said base (200) which is preformed with at least one area for receiving said cartridge (300) for the purpose of dissolving the reagent.

A floating dispenser for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser floating in an upright condition when a dispersant is present in a dispenser cartridge of the floating dispenser with the dispenser self inverting 180 degrees in response to consumption of the dispersant in the dispenser cartridge to thereby provide a visual alert that one should replace the dispenser cartridge in the dispenser with a fresh dispenser cartridge.

A method of making a dip tube for a liquid spray pump dispensing apparatus configured to provide substantial invisibility when disposed in a liquid fragrance product. To overcome the challenges of the prior art single layer dip tubes, a two-layer starting tube is provided. A first layer of the starting tube is made of a transparent (invisible in the liquid fragrance product) thermoplastic nonfluoropolymer, while a second layer of the starting tube is made of a dissolvable polymer. After assembly with the liquid spray pump dispensing apparatus, the second layer of the starting tube is dissolved in water or solvent (e.g., ethanol), leaving only the transparent nonfluoropolymer first layer as the dip tube. The thickness of the single layer dip tube can thus be reduced to enhance invisibility, with the dissolvable layer providing sufficient flexural strength for rigidity and desirable handling characteristics to the tube for required assembly to the pump assembly. The remaining single layer dip tube can then perform within the desired use/application (e.g., non-reactive to the fragrance and able to withstand repeated pumping for dispensing the fragrance.
