Abstract

A device adapted to release into an atmosphere a volatile liquid contained in an aerosol container, by means of the emission of liquid through a spray nozzle (2), the nozzle (2) additionally comprising means that provides at least two paths (5a, 5b) for the emission, at least one of which paths (5a, 5b) leads directly to the atmosphere and at least one of which paths (5a, 5b) leads to an absorbent material from which absorbed liquid can evaporate into the atmosphere over time. The device can supply simultaneously a charge of liquid, e.g., fragrance, for immediate effect, and an enduring effect from the absorbent material.

Description

FRAGRANCE DISPENSER COMPRISING A DOUBLE SPRAY NOZZLE SUPPLYING AN
EVAPORATOR AND THE AMBIENT AIR
This invention relates to aerosol-based devices for disseminating volatile liquids into an atmosphere. 5
The dissemination of volatile liquids, such as fragrances, malodour blockers, disinfectants, insecticides, fungicides and mildewicides, into an atmosphere is something often desired and can be achieved by a variety of means. One particularly desirable means is by means of an aerosol container, in which the liquid is contained with a propellant under pressure,0 and it exits from a nozzle when a valve is depressed, nozzle and valve commonly being incorporated in a single unit. The technology is cheap and reliable, and it is immediately effective, in that it provides a substantial charge of liquid in the atmosphere. However, it does suffer from the problem that it operates for only as long as the valve is depressed.
5 There have been numerous attempts to get around this problem, usually by placing adjacent to the nozzle an absorbent material, which absorbs the spray from the nozzle and then allows it to evaporate into the atmosphere, to give a long-lasting effect. This has the problem of losing the immediate charge. The way to overcome this is to provide an absorbent material which is movable relative to the nozzle, such that the nozzle can either0 spray directly into the atmosphere (giving the immediate effect) or into the absorbent material (to provide the long-lasting effect). However, this requires manual manipulation to give the desired effect.
It has now been found possible to overcome these deficiencies with a simple, reliable5 apparatus. There is therefore provided a device adapted to release into an atmosphere a volatile liquid contained in an aerosol container, by means of the emission of liquid through a spray nozzle, the nozzle additionally comprising means that provides at least two paths for the emission, at least one of which paths leads directly to the atmosphere and at least one of which paths leads to an absorbent material from which absorbed liquid can0 evaporate into the atmosphere over time. There is additionally provided a method of simultaneously providing in an atmosphere both an immediate charge of volatile liquid and a continuous emission of the volatile liquid, comprising the provision of the liquid in an aerosol container with a spray nozzle and the directing of a liquid spray from the nozzle partially directly into the atmosphere and partially into an absorbent material adapted to release the liquid over time.
The aerosol container for use in the invention is a standard container, having a pressure reservoir and a spray nozzle activated by applied pressure. The pressure may be by finger pressure, or it may be mechanical, for example, by means of an arm, rod or other means activated mechanically and/or electrically. The latter can be used in association with a timing switch or a remote control means, to operate the aerosol when desired. It is also possible naturally to have more than one such aerosol, such that the desired fragrance may be changed.
The spray nozzle of the device is configured such that a spray therefore will be directed simultaneously directly into the atmosphere and into an absorbent material capable of releasing the liquid into the atmosphere over time. This may be arranged in any convenient way, and the skilled person will readily be able to envisage numerous ways of carrying this into effect.
In one embodiment, the spray from the nozzle is directed into a conduit comprising a longitudinal divider, essentially dividing the conduit into two conduits, one of which leads directly to the atmosphere, the other of which leads to an absorbent material. The positioning of the divider can be such that a desired proportioning of the liquid between direct atmosphere emission and absorbent material emission can be achieved.
In another embodiment, there is located adjacent to the nozzle a member of extended surface area on which the spray directly impinges. This member is comprised at least partially of absorbent material and has at least one port, such that at least some of the spray can pass through into the atmosphere without being absorbed by the absorbent material. In a particular embodiment, the absorbent surface essentially completely surrounds the spray emerging from the nozzle. The member can take any suitable form. For example, it may be a planar or part-spherical surface of a suitable size and arranged at a suitable distance from the spray nozzle. In another embodiment, it may comprise a perforated chamber, which, apart from the ports, encloses the spray completely.
The extended surface may be a surface to which absorbent material is affixed, or the surface itself may be made completely of absorbent material. The natures of suitable materials are further discussed hereinunder. While it is possible that the surface may be of non-absorbent material with the only access to the atmosphere of absorbed spray through ports in the surface, it is preferred that the absorbent material itself present a disseminating surface to the atmosphere. This can be arranged in any convenient manner. For example, the absorbent surface may be supported on a net-like rigid structure, such that it has the desired access. Alternatively, the extended surface may be made of a suitably perforated, self-supporting absorbent material, such that no non-absorbent material is required.
The extent of the surface area will be governed by the absorption properties of the material and by the desired time of release into the atmosphere. Similarly, the size, number and location of the ports will decide on the quantity of direct spray into the atmosphere. AU of these characteristics can be easily determined by routine experimentation. The means of location of the extended surface member will depend on the nature of the device. It may be attached to the spray nozzle, or it may be fixed in a suitable location at another part of the device.
The nature of the absorbent material is not narrowly critical and the skilled person will easily be able to choose the appropriate material for each embodiment. Typical examples include, but are not limited to, woven and non- woven materials of cellulosic materials, porous metals, ceramics, absorbent foams, paper and cardboard, and porous plastics materials such as Porex™. In some cases, such as the chamber embodiment above, the entire chamber may be constructed of a self-supporting absorbent material. In other embodiments, the absorbent materials may be soft and supported on a suitable support. The devices of the invention are simply and inexpensively made, and they may be fitted to any standard aerosol. They are effective in operation.
The invention is further described with reference to the drawings, which depict preferred embodiments and which are not intended to be in any way limiting.
Figure 1 is a schematic longitudinal cross-section of one embodiment of the invention.
Figure 2 is a schematic longitudinal cross-section of another embodiment of the invention
In Figure 1, a valve stem 1 of an aerosol defines a channel 3, through which a volatile liquid is emitted. On the end of the valve stem is fitted a cap 2, by means of an orifice in the cap, which is a tight fit on the valve stem. Within this orifice is a partition 4, which extends longitudinally towards the valve stem. This partitions the orifice into two channels 5a and 5b, which go in different directions. At the ends of these channels are nozzles 6a and 6b that can be used to restrict or modify the spray pattern. The nozzle 6b leads directly to the atmosphere, the nozzle 6a leads to an absorbent material (not shown) than can absorb the volatile liquid and slowly release it over time.
In Figure 2, there is fitted to the valve stem 1 a cylindrical mounting 7 to which is fitted a hollow hemispherical cap 8, made of Porex™ porous plastics material. The cap has a series of ports 9, which allow liquid from the valve stem to exit directly into the atmosphere. The absorbent cap absorbs liquid, which it then releases over time.
The skilled person will appreciate that there are possible many variants of the invention all of which fall within the scope of the invention and which are realisable by means known to the art.
