An apparatus adapted to disseminate a volatile liquid, for example, a fragrance, into an atmosphere, the apparatus comprising a reservoir containing the liquid and a porous liquid transfer member through which the liquid is conveyed from the reservoir to the atmosphere and from which part extending into the atmosphere it is disseminated, the reservoir consisting of a collapsible bladder that reduces in volume responsive to atmospheric pressure and the loss of liquid, the porous transfer member being encased in an impermeable sleeve that is open to the liquid at that end of the member remote from the that part in the atmosphere, the transfer member additionally comprising at or adjacent to the open end means that interact with the collapsing bladder to maintain liquid contact with the transfer member. The apparatus is a simple and effective device that substantially solves the problems of leakage and complete utilisation of the volatile liquid,
An apparatus adapted to disseminate a volatile liquid into an atmosphere, the apparatus comprising a reservoir containing the liquid and a porous liquid transfer member through which the liquid is conveyed from the reservoir to the atmosphere and from which part extending into the atmosphere it is disseminated, the reservoir consisting of a collapsible bladder that reduces in volume responsive to atmospheric pressure and the loss of liquid, the porous transfer member being encased in an impermeable sleeve that is open to the liquid at that end of the member remote from the that part in the atmosphere, the transfer member additionally comprising at or adjacent to the open end means that interact with the collapsing bladder to maintain liquid contact with the transfer member.
An apparatus adapted to disseminate into an atmosphere one of two volatile liquids, the apparatus having, in use configuration, an upper and a lower reservoir, each containing one liquid and each equipped with a porous liquid transfer member that extends from the reservoir to the atmosphere, the transfer member being provided with an impermeable sleeve such that only that end of the transfer member remote from the end exposed to the atmosphere is open to the liquid, the apparatus being invertible, each reservoir consisting of a collapsible bladder that reduces in volume responsive to atmospheric pressure and the loss of liquid, and the transfer member additionally comprising, at or adjacent to the end open to the liquid, means that interact with the collapsing bladder to maintain liquid contact with the transfer member.
A method of disseminating into an atmosphere substantially the entirety of a volatile liquid contents in a reservoir having the form of a collapsible bladder sealed from the atmosphere and disseminating the liquid by means of a porous liquid transfer member extending from the reservoir into the atmosphere, comprising providing that portion of the transfer member with a liquid-impermeable sleeve open to the liquid at or near that end remote from the atmosphere, the transfer member additionally comprising at or adjacent to the open end means that interact with the collapsing bladder to maintain liquid contact with the transfer member.
