Abstract
A device is disclosed which allows the controllable transfer of a liquid, such as a perfume, a pharmaceutical agent, a masking agent, an insecticide or an organoleptic substance, through an outlet opening of a container. This device includes a holder with a fitting designed to embrace a capillary medium and to fit into the opening in such a way that liquid is only transferable through the opening by the capillary medium. The holder, adjacent to the fitting, further includes a sleeve which further embraces the capillary medium at least at a length which is chosen in such a way that, in a first vertical position of the sleeve liquid has access, and in a second, inverse, vertical position of the sleeve liquid has no access to the capillary medium. An apparatus is also provided in which at least one device is installed on a rotor.
Description
- The present invention relates to a device for the controllable transfer of a liquid, and an apparatus for dispensing transferred liquids with at least one of the devices.
- In order to transfer liquids it is known to use capillary action which is dependent on the cohesion forces within the liquid and the adhesion forces of the liquid to a porous capillary medium containing small channels for the transfer of the liquid. Such a capillary medium, being introduced through an opening into a container, can therefore transfer a liquid out of the container by means of capillary action. The transferred liquid may be used to distribute chemical substances to the ambient air in order to mask or generate an odor, to evoke a medical or organoleptic effect, or to affect insects.
- In order to stop the transfer of liquid the capillary medium must be removed or covered, which is inconvenient and may cause further distribution of the remaining liquid on the cover or the removed capillary medium. The use of two or more liquids increases the inconvenience accordingly.
- The present invention is a device, which allows an easily controllable transfer of a liquid through a capillary medium and an apparatus for dispensing transferred liquids with at least one of the devices.
- The invention allows the controllable transfer of a liquid, such as a perfume, a pharmaceutical agent, a masking agent, an insecticide, or an organoleptic substance, by a first capillary medium such as a scrib-rod from a container preferably to a second capillary medium such as a gauze. The first capillary medium is inserted into a holder containing a fitting being designed to embrace the capillary medium, and to fit into an opening of the container. The holder further containing a preferably non-porous sleeve, which further embraces the capillary medium at least at a length which is chosen in such a way, that, in a first vertical position of the sleeve, liquid has access and in a second, inverse, vertical position of the sleeve the liquid has no access to the capillary medium.
- The invention is therefore easily controllable by turning it from a first to a second position.
- In a preferred embodiment of the device, the end of the sleeve extends to a side-wall of the container in such a way that in a third, horizontal position of the container access of the liquid to the capillary medium is prevented as well. This embodiment is used for an apparatus containing two devices which in positions one and two are activated alternatively and which are both deactivated in the third position. A further advantage of this embodiment is, that two or more liquids may be diffused separately.
- In a further embodiment, the first capillary medium is connected to a second capillary medium such as a gauze or an extended portion of the first capillary medium, from which the transferred liquid is diffused preferably under the support of an air flow generated by a fan.
- In a further embodiment, the device includes an annular container with one or more, preferably three, compartments respective reservoirs filled with different liquids which through a first capillary medium are guided to a second capillary medium which is embraced by the container. The annular container may be molded in one piece which can be produced at low cost. The annular container may, however, also consist of segments which can be separated, for example for the refill of the liquids, and combined afterwards. Using an annular container also facilitates handling of the device and integration into an apparatus which automatically turns the device into positions in which transfer of selected liquids is initiated or terminated. For this purpose the outer surface of the device, which is held in a bearing, may be in contact with a drive wheel.
- In a further embodiment of the device, the holder for the first capillary medium may be integrated into the containers of the inventive devices.
- The first and the second capillary medium may be made in one piece. This would be especially advantageous in cases where the container is to be disassembled and reassembled, embracing the second capillary medium in the center.
- The inventive apparatus, which allows dispensing of transferred liquids, contains at least one inventive device as described above being rotatably mounted on an axis of a stator between at least a first vertical and a second vertical thereto in inverse position.
- One embodiment of the apparatus contains two inventive devices arranged towards each other along the same axis on a rotor with the second capillary medium oriented towards the center of the rotor in such a way that in a first position of the rotor, only one of the devices and in the second position, the other one of the devices transfers the liquid.
- The apparatus is preferably equipped with a control unit containing a sensor for detecting the position of the rotor. The control unit is able to actuate the air flow generator and/or to control the air flow depending on the position of the rotor.
- In the third position, the diffusion of the liquid is therefore immediately stopped because liquid is no longer transferred by the first capillary medium, and no longer diffused from the second capillary medium.
- In a further embodiment the apparatus may be fully automated.

FIG. 14 shows asegment 102 a′ of an annular container. -
FIG. 1 shows a firstcapillary medium 3 and a holder 10 (in a sectional view) containing afitting 11 with aflange 12. Thefitting 11 is connected to asleeve 13. Fitting 11 andsleeve 13 build a tube with achannel 15 into which thecapillary medium 3 may be inserted. -
FIG. 2 shows theholder 10 with the installedcapillary medium 3. The length of thecapillary medium 3 is chosen in such a way that it is longer than, i.e. extends beyond fitting 11 andsleeve 13 combined. When installed, oneend 31 of thecapillary medium 3 will extend out of thesleeve 13 atend 14, and the other end of thecapillary medium 32 extends out of thefitting 11, which tightly seals theopening 22 of the container (FIG. 3 ) after the installation. -
FIG. 3 shows in a sectional view acontainer 20 with anopening 22 and acorresponding fitting 24, which is suitable to receive thefitting 11 of theholder 10 in such a way that thesleeve 13 is inserted into thecontainer 20 and theflange 12 rests on thefitting 24 of thecontainer 20 which is filled with aliquid 21 such as a perfume, a pharmaceutical agent, a masking agent, an insecticide or an organoleptic substance. Further shown is acover 25 with anopening 26 through which thecapillary medium 3 may be guided. Thecover 25 may be screwed onto thefitting 24 of thecontainer 20. -
FIG. 4 shows thecontainer 20 with theholder 10 and thecapillary medium 3 installed. Due to the tight sitting of thefitting 11 in the opening 22 and the tight sitting of thecapillary medium 3 in thechannel 15 of theholder 10 theliquid 21 is only transferable through the opening 22 through thecapillary medium 3 by capillary action. Theliquid 21 can enter only at theend 31 of thecapillary medium 3 at theend 14 of thesleeve 13 because thesleeve 13 shields the remaining part of thecapillary medium 3, introduced into thecontainer 20, against theliquid 21. Theend 14 of thesleeve 13 of the installedholder 10 preferably extends to a region close to thebottom 23 of thecontainer 20. - Therefore, when turning the
container 20 upside down, as shown inFIG. 5 , theliquid 21 has no access to thecapillary medium 3 which is shielded by thesleeve 13. Only in the case where thecontainer 20 was filled more than 95%, could liquid reach thecapillary medium 3. Thecapillary medium 3 and thesleeve 13, however, could also be extended to thebottom 23 of thecontainer 20, containing in there narrow channels for theliquid 21 to pass through to thecapillary medium 3. -
FIG. 6 shows a modifiedcontainer 201 comprising tworeservoirs wall 202, which receive theliquid 21 whenever thecontainer 201 is turned into horizontal alignment. A clockwise rotation of thecontainer 201 will cause the liquid 21 to enterreservoir 204 b. A counter-clockwise rotation will cause the liquid 21 to enterreservoir 204 a. The liquid 21 will therefore not be in contact with thecapillary medium 3 in either horizontal orientation of thecontainer 21. Thereservoirs wall 202. The modifiedcontainers 201 are recommended for the use in arrangements containing three or moreinventive devices FIG. 9 , modifiedcontainers 201 could therefore advantageously be installed. -

From the first or secondcapillary medium FIG. 8, 9 , or 10) is forwarded to the environment. -
FIG. 8 shows the arrangement ofFIG. 7 installed in acontainer 20 of a first and a secondinventive device 1 x and 1 y, respectively. Thefirst device 1 x is oriented as thedevice 1 shown inFIG. 4 . As explained above, in thisorientation liquid 21 is transferred by thecapillary medium 3. The second device 1 y is oriented as thedevice 1 shown inFIG. 5 preventing the transfer ofliquid 21. -

Thethird device 1 z is transferring liquid 21 through thecapillary media devices 1 x, 1 y, which contain only a small amount ofliquid 21. Turning the arrangement around axis v by 90°, will cause transfer ofliquid 21 to stop indevice 1 z as well. However, turning the arrangement around an axis w, which is perpendicular to the axis u and v, to the left or to the right by 90° will start transfer ofliquid 21 in one of thedevices 1 x respective 1 y while transfer ofliquid 21 in thedevice 1 z will cease. - Adding two
inventive devices 1 aligned along axis w will extend the arrangement to fivedevices 1 which may be turned around axis v or w into corresponding positions where liquid 21 is transferred in thecorresponding devices 1. - In order to allow the use of larger volumes of
liquid 21 thedevices container 201 as shown inFIG. 6 andFIG. 9 (insert). - Of course, the vertical and horizontal alignment need not be exact and may vary in a broad angle depending on the percentage of liquid 21 in the
containers 20; 201 and the form (bent, straight) and length of thesleeve 13. - It is also possible to use a single
inventive device 1 preferably in a housing which may be located on a surface in at least two positions in such away that in both positions (inverse and not inverse) thedevice 1 is at least approximately vertically aligned. -
FIG. 10 shows an inventive apparatus for dispensingliquids 21 comprising a stator 7 which, on aaxis 71, carries arotor 9 with two axially alignedinventive devices 1 x, 1 y. Possible is also the installation of only onedevice 1 x in the apparatus. In the position as shown, only the lower device 1 y is transferring liquid 21 through the first and secondcapillary medium 3; 5 from where it is forwarded to the environment by a flow ofair 28 being generated by afan 4, which is preferably located in the stator 7. Theair flow 28 is preferably guided inchannels 93 in therotor 9 and in the stator 7 in order to maximize the efficiency. Thesecond capillary media 5 of the first and thesecond device 1 x, 1 y may be framed and isolated from each other by aframe 91 containingopenings 92 for theair flow 28. Therotor 9 can now be turned between at least a first position, e.g. as shown inFIG. 10 and a position in which therotor 9 is turned by 180°. In the first position, liquid 21 from the first device 1 y is transferred and diffused, while no liquid 21 is transferred in thesecond device 1 x. In thesecond position liquid 21 is transferred in thesecond device 1 x while no liquid 21 is transferred in the first device 1 y. The liquid 21 to be diffused can therefore easily be selected by turning therotor 9. In case that no liquid 21 should be diffused thedevices 1 x and 1 y are brought into a third position where they are horizontally aligned. In case that this third position is used in the apparatus, then preferably thecontainers 201 shown inFIG. 6 are installed. - The positions of the
rotor 9 are preferably detected by asensor 62 which is connected to acontrol unit 6 which is controlling thefan 4 and/or amotor 63 which, in a preferred embodiment, is used to turn the rotor between positions. In case that therotor 9 reaches the third position driven by themotor 63 or manually thefan 4 is switched off by thecontrol unit 6 because no liquid is transferred in this position. In a further embodiment, depending on the input from asensor 65, which measures temperature and/or humidity, thecontrol unit 6 adjusts the air flow generated by thefan 4 or actuatesfan 4 androtor 9 in a suitable way. - The electrical devices in the apparatus are connected to a
power supply 64. In order to control the apparatus, preferably one or more control buttons 61 (mains switch, etc.) are installed. The apparatus may also be programmable and equipped with a timer. The apparatus may rest on asupport 73 or may be installed on the wall by correspondingmeans 72. -
FIG. 11 shows aninventive device 101 with anannular container 2000 containing one reservoir which is filled with a liquid 21. Theannular container 2000, which may also have a toroidal form, embraces acylindrical capillary medium 5 such as a gauze or an extended portion of a first capillary medium which is embraced by aholder 10. As described above, theholder 10 is inserted into thecontainer 2000 in such a way that in the position shown inFIG. 11 ,liquid 21 is transferred through the first capillary medium. With a turn of thedevice 101, theholder 10 is lifted out of the liquid 21 thus preventing the transfer of the liquid 21. -
FIG. 12 shows aninventive device 102 with anannular container 2001 with threereservoirs holder FIG. 12 the liquid 21 a is transferred through the first capillary medium in theholder 10 a to the secondcapillary medium 5. Transfer and distribution of theother liquids device 102 by approximately 120° to the left or to the right. -
FIG. 13 shows theinventive device 102 ofFIG. 12 cut along line A-A. It is shown that anair flow generator 4 is installed behind the secondcapillary medium 5 in such a way that the air flow generated is driven through the secondcapillary medium 5 thus distributing the transferred liquid 21 a. The secondcapillary medium 5 can be formed of one piece, allowing the liquids to get mixed, or three pieces separated from each other, preventing the liquids from being mixed. The number ofreservoirs 102 can be two, three or more. - The
annular container 2001 of theinventive device 102 shown inFIG. 12 can be molded in one piece. Thecontainer 2001, however, can also be composed of threediscrete segments 102 a′ as shown inFIG. 14 . The shownsegment 102 a′ preferably comprises means 102 x, 102 y for interconnecting all segments. - The
holder 10′ for the firstcapillary medium 3 is incorporated into thesegment 102 a′. Handling of this device is therefore facilitated, since liquid 21 a can be refilled without removing the holder. Incorporation of theholder 10 can advantageously also be done in thecontainers FIG. 1 toFIG. 10 . - The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention and all such modifications are intended to be included within the scope of the following claims.
