A scent diffuser contains: a body, a power connection unit, a pump, and a diffusing device. The body includes an accommodation chamber and a first opening. The power connection unit is housed in the accommodation chamber. The pump includes an air inflow segment and an air outflow segment. The diffusing device is accommodated in the body and includes a cap, a nozzle, a spraying member, a holder, and a spray hose. The cap has a first orifice, a second orifice, and a third orifice. The spraying member has a receiving groove, a suction mouth, and an outlet. The nozzle has a shrinkage conduit and a narrow conduit, and a slit is defined between the nozzle of the diffusing device and the receiving groove of the spraying member. The holder has a connection portion, and the cap is coupled on the holder.

A carbonation machine may include a carbonation head, a holder that is configured to hold a gas canister, the holder comprising a connector with a socket configured to enable linear insertion of a valve of the canister into the socket, the socket including a seal with at least one lateral opening to enable fluidic flow between one or more laterally oriented ports of the valve and a conduit of the holder while preventing leakage of gas from the fluidic flow, and a holding mechanism configured to hold a lateral projection from the canister after insertion of the valve into the socket such that the valve remains in the socket, and an activation mechanism configured to operate the valve to release the gas from the canister when inserted into the socket so as to enable the gas to flow via the conduit to the carbonation head.

Device having a vessel containing a fluid product dose, a compressed gas vessel for dispensing a dose of compressed gas to expel the dose of fluid product, and an intermediate portion having a body and a connection for connecting the vessel to the compressed gas vessel, and an actuating mechanism. The connection has first and second support members and a deformable tube attached thereto. The first support member has a first opening mechanism for opening the vessel and the second support member has a second opening mechanism for opening the compressed gas vessel. A spring is between the first and second support members, the actuating mechanism has a button rigidly connected to a cage which locks the support members axially. When the button is moved radially, the support members are unlocked and the spring moves the two support members towards their actuating positions.

The invention provides a water-activatable luminescent particulate material (1) comprising particles (100), wherein each particle (100) comprises a solid state light source (10) functionally coupled with a water-activatable battery (20) and a water absorbing shell (120) enclosing at least part of the water-activatable battery (20). The invention also provides a luminescent particulate material spray device comprising a container configured to host the water-activatable luminescent particulate material.

A pressurized dispenser includes a base and a peripheral wall having an open end sealed by a dispensing element comprising a dip-tube, a fluid reservoir in contact with the dip-tube for reducing the compressed gas lost from the pressurized dispenser, a compressed gas and a dispensing liquid. In embodiments, a majority of the fluid reservoir may be located outside of the dip-tube, and the fluid reservoir may include a porous material, arranged in use to hold a volume of the dispensing liquid. Such porous material may be configured so that, in use, at least a portion of any compressed gas in the reservoir can be displaced by the liquid, ejecting such portion of the compressed gas into the dispenser. In embodiments, the dispensing element may be configured to dispense dispensing liquid continuously for at least 0.5 seconds, upon actuation of the dispensing element.
