Additive dispenser

#This application relates to a dosing apparatus for dispensing a set volume of a non-gaseous fluid at a set rate. The concepts disclosed herein may have particular application for sanitary applications, such as adding an essential oil, soap, shower gel or the likes to a water stream in a shower, tap or toilet, to absorbent scent pads, hand towels, or the likes, but it need not be limited to these uses. The application also relates to an adapter arranged to be removably attachable to both the dosing apparatus, of which it may form a part, and a standard essential oil bottle, and to fluidly connect the essential oil bottle to the dosing apparatus.

#In the prior art, it is known to add bath oils, aromatherapy oils, and/or other additives to water streams, for example in showers, bidets, toilets, baths and basins. The rate at which the additive is dispensed is influenced by the flow rate of the water stream, however, which can lead to unexpected effects for a user (e.g. a pressure surge early in a shower resulting in their being no fragrance left when desired).

#More precise control of the volume of additive dispensed is also desirable, so as to extend the useful life of a container of additive, and/or to achieve more consistent results.

#Embodiments will now be described in more detail by way of example only with reference to the accompanying drawings in which like reference numerals are used for like features:

#FIG. 1 is a schematic front view of a dosing apparatus of an embodiment;

#FIG. 2 is a schematic top view of the dosing apparatus of FIG. 1;

#For convenience, the concepts are described herein in the context of adding an essential oil (also known as an aromatherapy oil) to a liquid stream (e.g. water).

#According to a first aspect, there is provided a liquid dosing apparatus for dispensing a liquid from a container into a liquid stream of a shower, toilet or tap. The apparatus comprises:

#a dosing mechanism comprising a dosing chamber and a moveable member, and arranged to draw a set volume of the liquid into the dosing chamber on activation, activation comprising moving the moveable member in a first direction;
