The invention also relates to a specific dispenser which may use the above cited prefill.
Description
Refill for dispensing a volatile active ingredient Field of invention The invention relates to the controlled diffusion of a volatile active ingredient for e.g. deodorizing, disinfecting, humidifying or keeping mosquitoes away.
State of the art A device for dispensing a volatile active ingredient generally comprises a support for holding the volatile active ingredient. The device may also include a blower , e.g. a fan, and a battery. Such a device is disclosed in US 5 376 338. In this case the support extends around the battery and is adapted to hold a porous block which is impregnated with a volatile active ingredient.
Alternatively, the support may consist of a cup with an annular recess adapted to receive a volatile active ingredient being in the form of a liquid, a gel or a porous block.
Summary of the invention One object of the invention is to provide a refill for the devices previously defined.
The refill of the invention combines the advantages of a volatile active ingredient being in the form of a liquid,.a gel or a porous block.
Another object of the invention is to provide a device which may be used with the new refill.
To this effect, the invention concerns a refill for a volatile active ingredient dispenser comprising a reservoir containing a volatile active ingredient in liquid or gel form, said reservoir comprising a wall consisting of a diffusing membrane.
The refill of the invention is characterized by the fact that it is adapted to be held in a circular support such as an annular recess.

To this effect, the invention concerns a refill for a volatile active ingredient dispenser comprising a reservoir containing a volatile active ingredient in liquid or gel form, said reservoir comprising a wall consisting of a diffusing membrane.
The refill of the invention is characterized by the fact that it is adapted to be held in a circular support such as an annular recess.
Some embodiments of the invention are listed below in a non-exhaustive manner:
- Membrane based refill for perfume/mosquito killer dispenser with the liquid contained in 4, 5, 6 or more reservoirs in a row to allow the wrapping of it in round form.
- The refill comprises channels between the reservoirs to equalize the level once installed.
- The membrane faces the internal part of the wrapped foil (once installed) to fully use the air flow passing trough it in a forced/natural air flow.
- The refill is wrapped with the membrane on the external part to take full advantage of natural/forced air flow for a better diffusion of the active principle.
- The refill with no channels between the reservoirs to allow the user to custom-fit the diffusing surface by cutting it with any meaning to trim the diffusing area.
- The reservoirs are arranged in a sheet where the user can cut by any meaning the desired part of them.
- More in general a diffuser refill for liquids and gels where the diffusion rate is trimmed by the user by cutting a desired quantity of elements, intending as element a confined zone where there is a volume to contain the liquid and a membrane to dispense it.
- The refill with a sealing sheet that prevents unwanted diffusion and that can be peeled off to activate the diffusion.
- The peel-off sheet that offers, on the sheet borders, pre-cut ears to ease the peeling of it.

Refill specific example A barex film is thermoformed in a strip with six cavities filled with liquid fragrance (an automatic production machine takes care of all the process, from the foil to the finished product).
A porous membrane is applied to close the cavities and an alluminium peel-off cover is applied over it ( the picture shows the back of the cavities, the membrane is on the hidden face).
A permanent (i.e. non disposable) cup.
The plastic cup, formerly a part of the refill, is now just an adapter to fit the refill in the dispenser and doesnt' have to be replaced once fitted.
The operator peel away the alluminium sheet from the refill, exposing the membrane, ply the refill along the ribs in an hexagon-like shape and insert it in the adapter (inner ribs are holding it in place).
The cup is ready to receive the battery and to be inserted into the dispenser.
Advantages Minimal packaging cost overhead respect to the cost of the fragrance itself.
Air tight seal of the perfume in the refill up to the opening (long shell life).
No-glue approach (thermal seals) with high resistance to environmental stresses in handling and storing.
Improved logistic cost with reduced volume occupied by each refill (very close to the liquid volume only). .
Very high performance results (the cavity's shape helps a constant release all through the refill's life) and full freedom in fragrance choice.
Highly automated process with production capabilities in the plant more than double the requested quantities.

Dramatically reduced waste.
No refilling possible of the exausted charge.
The peel-off seal can be used to sign the exchange date.
Lowest parts count available.
An embodiment of the invention is shown in the attached figures.
Figure 1 illustrates a refill according to the invention Figure 2 shows the introduction of the refill of figure 1 into a cup Figure 3 shows a cup containing refill The refill 1 shown in figure 1 is made of a thermoformed sheet containing six cavities. Each cavity forms a reservoir 7. The reservoirs 7 and the space around them are covered by a single diffusing layer, acting as a diffusing membrane 4 for each reservoir 7. The reservoirs 7 are connected to each others via channels 2.
When the refill 1 is not used, the external face of the diffusing layer is covered by a peel-off aluminum sheet 3.
Figure 2 shows the introduction of the refill 1 into an annular recess 6 forming part of a support 5. Before its introduction in the annular recess 6, the refill 1 is bent in order to form an annular shape.
Figure 3 shows the refill 1 in the annular recess 6.
The support 5 is then installed in a dispenser (not illustrated) which, advantageously comprises a fan.
When the refill 1 is used, it may be easily replaced by a new one. The support can be re-used.
