Fluid delivery systems, methods and apparatus to dispense a dose of fluid on an animal, which may be particularly used for behavior modification of the animal, are disclosed. A system may particularly comprise an apparatus wearable by the animal. The apparatus is suitable for storing a fluid contained therein, and dispensing a dose of fluid on the animal, particularly to spur or otherwise induce behavior modification of the animal, particularly in response to training stimuli during a training scenario.

Various embodiments of a metered dose inhaler that includes a metering valve are disclosed. The inhaler includes a reservoir containing a pressurized formulation of medicament and carbon dioxide. The metering valve includes a metering chamber, a metering valve stem, and a metering valve stem seal having an opening through which the metering valve stem passes to form a dynamic seal between the metering valve stem and outside atmosphere. The metering valve stem seal has a Shore D hardness of 45 to 80 and its opening is adapted to be stretched wider by the metering valve stem passing through it than it would be absent the valve stem.

The present invention discloses an aerosol container (100) comprising a body (101) divided into a first chamber (10) and a second chamber (20) by a divider (102), in which the first chamber (10) is under atmospheric pressure and configured to receive a customisable content through an inlet (200) at the body (101) either or both during and after production of the aerosol container (100), and the second chamber (20) is under a pressurised environment and prefilled with a pressurised content; wherein the body (101) includes a mechanism (104) which, when activated, acts on the divider (102) so as to allow mixing of the customisable content and pressurised content to form a mixture to be dispensed from the body (101) through an outlet (300).

A refill for an inhaler, the refill including a cylinder with an axis and containing a pressurised inhalable composition. An outlet valve at one end has a hollow valve stem extending axially from the cylinder. A cap is fitted onto the cylinder at the outlet end and extends axially beyond the valve stem. The cap has an internal passage extending through the cap to allow access to the valve stem. The internal passage provides a guide wall to guide the inhaler onto the stem during the refill process.

A portable apparatus for dispensing and foaming of a product, including: a product container which contains a product that is to be foamed by and dispensed from the apparatus; a gas container, at least containing a gas, for example a single gas or a gas mixture, wherein the gas substantially does not contain any greenhouse gases such as N20; a dispersion device, having a product entrance that is connectable to the product container for receiving product, the dispersion device further being connectable to the gas container for supplying the gas to the product during product discharge; a processing device downstream of the dispersion device for performing a mixing treatment and/or pressure reduction on the product provided with the gas; and a product dispensing head, being part of a top section of the apparatus and being arranged downstream of the processing device.
