Definitions

  • Dispenser for dispensing volatile materials, especially for dispensing fragrances and/or active substances
  • the invention refers to a dispenser for dispensing volatile materials, especially for dispensing fragrances and/or active substances, according to the preamble of claim 1.
  • the invention further refers to a method for operating a dispenser according to the preamble of claim 34.
  • Various volatile material dispensers are known in the prior art and generally include a housing with a container inserted therein.
  • the container generally holds a volatile material therein.
  • the volatile material is passively emitted therefrom.
  • a diffusion element is utilized to facilitate the dispensing of the volatile material. Examples of diffusion elements include heaters, piezoelectric elements, fans, aerosol actuators, and the like. It is generally known to insert the container into the housing of a dispenser from below, with respect to its use position and viewed in the vertical axis direction. A wick is regularly held in the container as a capillary element, by means of which the volatile material is then transported from the container to a free wick end projecting from the container.
  • This free wick end forms a delivery zone at which the volatile material is discharged from the free wick end of the wick, possibly assisted by an air stream and/or assisted by a heating element, so that an air stream enriched with the volatile material can escape into the environment of the dispenser.
  • a conventional setup is known, for example, from EP 3 235 518 A1 .
  • a dispenser for dispensing volatile materials is proposed with a housing comprising a container in which a volatile material to be dispensed to the environment is accommodated. Furthermore, a capillary element is provided by means of which a volatile material dispensed from the container can be conveyed by the capillary effect in a predetermined direction, preferably in the direction of a delivery zone of the capillary element.
  • At least a discharge point of the container, through which the volatile material is dischargeable from the container, preferably the entire container, is arranged above the capillary element in relation to the use position of the dispenser and viewed in the vertical axial direction, so that the volatile material is suppliable from above to an upper end section of the capillary element and, starting from this upper end section, is conveyable further downwards by the capillary action of the capillary element.
  • the inventors tests have shown that the liquid weight of the volatile material in the capillary element is also significantly greater in the solution according to the invention, in which top loading takes place, than in the dispenser systems loaded only from below. According to the inventors, this is due to the fact, without again being bound by this theory, that the volatile material permanently flowing in from above prevents the capillary element from drying out quickly, as can be the case with conventional devices loaded from below. The latter applies in particular if, as will be described in detail below, additional measures are taken to wet the capillary element with the volatile material from below as well.
  • the dispenser according to the invention can be used in conjunction with all suitable and desired volatile materials, regardless of whether this involves pure fragrance delivery or pure active substance delivery or combined fragrance and active substance delivery.
  • the application in the field of air care or in the field of pest control is also possible at any time with such a device according to the invention.
  • the discharge point in relation to the vertical axis direction, forms the lowest point of the container.
  • the capillary element directly adjoins the discharge point with its upper end section. This provides a particularly advantageous, functionally reliable transfer of the volatile material from the container to the capillary element.
  • the discharge at the discharge point could be carried out in such a way that the container has a valve which is opened when contact is made with the free upper end section of the capillary element in order to enable the discharge of the volatile material, and which is closed again when no contact is made with the capillary element in order to stop the discharge of the volatile material.
  • the upper end section of the capillary element has a piercing element and/or the upper end section of the capillary element is formed by a piercing element.
  • a container wall area of the container can be pierced in a volatile materialdelivery position of the container to form the discharge point, so that in the pierced state of the container wall area volatile material can be delivered through the discharge point.
  • the container can be connected to the housing, preferably detachably, in such a way that when the container is connected to the housing, a downward displacement movement of the container in relation to the vertical axis direction takes place in the direction of the piercing element, whereby the piercing element pierces the container wall area after a defined displacement path in the volatile material delivery position.
  • the container can be connected to the housing by means of a screw connection. The latter can be produced particularly easily and reliably with high precision and also ensures controlled piercing by means of the piercing element when inserting the container.
  • the container is connected non- detachably, but in relation to the vertical axis direction, downwards displaceable towards the piercing element, such that the container, starting from an unpierced use position, pierces the container wall area of the container after a defined displacement path in the volatile material-delivery position when displaced towards the piercing element.
  • the container is guided along a linear guiding device on the container.
  • a functionally reliable outflow of the volatile material from the container, combined with a functionally reliable overflow to the capillary element, results, for example, if the piercing element is designed in the form of a hollow needle, via whose inner cavity the volatile material flowing out of the container at the discharge point overflows or flows into the hollow needle.
  • the container wall area forming the discharge point is formed by a material, preferably an elastomer material, which encloses, preferably tightly encloses, the piercing element on its outside in the pierced state and/or which contracts again after removal of the piercing element and closes, preferably tightly closes, the piercing point.
  • this container wall area is a soft plastic part that will spring back to close the perforated area when the needle is removed.
  • An example of such a material is silicone. Provided that the material is able to contract again after removal of the piercing element and thus close the puncture site, this has the advantage that the container can then also be transferred back to a non-use position in which no volatile material is released.
  • the container wall area forms at least part of a side wall of the container.
  • the container wall area is formed by a sealing element inserted into the bottle neck opening.
  • the free end of the hollow needle forming a pointed end is asymmetrical and has point areas projecting at different distances from the free end of the hollow needle. This ensures smoother penetration or perforation.
  • the container is provided with a pressure compensation valve, preferably on the opposite side of the discharge point with respect to the vertical axis direction, which is configured in such a way that, when the volatile material escapes via the discharge point, air from the environment flows into the container for pressure compensation and that no volatile material escapes from the container.
  • a pressure compensation valve can be formed by a membrane covering an air inlet opening, which forms or fulfils these functionalities.
  • the piercing element has a widening wall section which widens downwards and outwards in relation to the vertical axis direction, in particular a widening wall section which widens downwards and outwards in a conical and/or funnel-shaped manner, it preferably being provided that the widening wall section encloses a piercing element cavity.
  • a capillary element portion having or forming the delivery zone adjoins a lower piercing element end, with respect to the vertical axis direction, which faces away from the container, in such a way that the volatile material flows along the inside and/or along the outside of the widening wall section downwards to the capillary element portion having or forming the delivery zone of the capillary element.
  • the widening wall section which widens downwards and outwards, a very good and controlled transfer and distribution of the volatile material flowing out of the container towards the capillary element portion having or forming the delivery zone can be achieved.
  • the widening wall section is made of a material that has no capillary effect, for example a plastic material without capillary effect.
  • the widening wall section could also be made at least partially of a material having a capillary effect, or the widening wall section could be coated on its outside and/or inside at least partially with a material having a capillary effect.
  • the capillary element portion comprising or forming the delivery zone of the capillary element is formed by a tube extending downward with respect to the vertical axis direction and enclosing a tube cavity at least partially, preferably completely.
  • a tube wall forming the tube can be produced at least partially, preferably completely, from a material having a capillary effect.
  • the tube wall forming the tube can be coated at least partially, preferably completely, on its outer side and/or its inner side with a material having a capillary effect. In each case, this ensures that the volatile material is reliably conveyable by means of the tube from an upper tube end to a lower tube end, as seen in the vertical axis direction.
  • the upper tube end can be detachably connected to the lower piercing element end by means of a plug connection. This is done, for example, in such a way that the lower piercing element end has an annular insertion section extending in the direction of the vertical axis, into which the upper tube end can be inserted with an associated insertion section, in particular by contacting the lower widening wall section of the piercing element.
  • a material with a capillary effect there are different possibilities for the use of a material with a capillary effect.
  • a particularly simple and technically reliable solution is, for example, when the capillary effect material is formed by a fibre paper and/or an absorbent paper.
  • Such paper materials have the particular advantage that they can be easily cut to size and formed into the desired tubular shape.
  • the use is of course not limited to such paper materials.
  • Other materials can of course also be used, for example porous materials such as foamed plastic materials.
  • a plurality of tube openings spaced apart from one another are formed in the tube wall and extend in the vertical axis direction and in the circumferential direction over at least part of the tube wall.
  • the capillary element can be brought into contact at least in the delivery zone with an ambient air flow and/or with a forced air flow, so that the ambient air flow and/or the forced air flow is enriched with the volatile material stored in the delivery zone and flows away from the delivery zone.
  • a forced air flow this can be achieved, for example, by means of a fan and/or heater, or the like.
  • the capillary element is configured and arranged in such a way that the ambient air flow and/or the forced air flow impinges on at least one tube outer impact and/or contact area of the delivery zone, accumulates volatile material there, further flows through the at least one tube opening located in the region of the at least one tube outer impact and/or contact area into the tube cavity and there further flows to at least one tube inner impact and/or contact area, further enriches itself there with volatile material and flows out of the delivery zone through the at least one tube opening located in the region of the at least one tube inner impact and/or contact area.
  • this air flow can be directed in such a way that it flows from a first tube outer impact and/or contact area into the tube cavity and then flows to a tube inner impact and/or contact area opposite the tube outer impact and/or contact area in the direction of flow.
  • the tube itself can in principle be designed differently, depending on the specific dispenser structure, i.e. that, in the assembled state, the tube is configured to surround the tube cavity at least partially, preferably to a large extent, most preferably completely, in circumferential direction.
  • the tube in the assembled state, is formed from a flexible and rectangular material web.
  • the housing in relation to the vertical axis direction, has a reservoir as a collection room on an underside of the capillary element facing away from the container, in which the volatile material dripping from the capillary element and/or from the container can be collected.
  • a lower end section of the capillary element facing away from the container with respect to the vertical axis direction projects into the reservoir and, depending on the filling level of the volatile material in the reservoir, possibly dips into the volatile material collected there, so that the volatile material - depending on the volatile material saturation level of the capillary element - is suckable in by means of the with respect to the vertical axis direction lower end section of the capillary element and/or is conveyable upwards with respect to the vertical axis direction.
  • the reservoir has an annular circumferential collection room corresponding to the circumferential tube geometry of the tube, into which the lower tube end projects.
  • the reservoir has a central dome section surrounded by the annular collection room, which is convexly curved upwards with respect to the vertical axis direction and lies geodetically higher than the collection room, so that the volatile material impinging on the dome section, in particular dripping directly downwards from the container, flows in a simple manner towards the collection room. This ensures in a simple way that no volatile material is lost and thus a complete consumption of the volatile material is guaranteed.
  • the reservoir has a holder part which faces the tube and in which the tube is detachably held with its lower tube end, preferably detachably held in such a way that the tube has at the lower tube end at least one downwardly projecting holding finger which engages through an associated recess in the region of the holder part and projects into the collection space located therebelow.
  • the holder part can be formed by a separate first component of the reservoir, which is detachably connected to a second component of the reservoir forming the collection room, preferably by means of a quick release connection, most preferably with a clip connection as quick release connection.
  • a quick release connection most preferably with a clip connection as quick release connection.
  • the dome section is part of the holder part.
  • the reservoir is flat on its underside in relation to the vertical axis direction. This means that the reservoir can then also form a standing surface of the dispenser.
  • the housing itself can be designed in different ways.
  • the housing has a housing shell which surrounds the capillary element, with respect to the circumferential direction, at least partially, preferably completely, and at a distance, and that the housing shell receives and supports the container approximately centrally on its upper side, so that the container is arranged above the capillary element in relation to the use position of the dispenser and as seen in the vertical axis direction.
  • Another preferred design is one in which the reservoir is arranged on the side of the housing opposite the container in the vertical axis direction, so that the housing shell is essentially arranged between the container and the reservoir. This makes it easy to realize a compact, stylish design, as already explained above.
  • the housing shell is held with its lower end section, relative to the vertical axis direction, by means of a plug connection to a plug receiving element of the reservoir, preferably to a plug receiving element formed in the region of the holding part.
  • the housing shell has, at least in the region and/or at the level of the delivery zone of the capillary element, a plurality of spaced-apart air passage openings which extend in the vertical axis direction and in the circumferential direction over at least a partial region of the housing shell.
  • the housing shell can have a round or angular or oval outer geometry, to name just a few examples.
  • Mixed forms of various different geometries are of course also possible.
  • the object according to the invention is solved by a method for operating a dispenser.
  • the advantages resulting therefrom are identical with those of the device previously mentioned in detail, so that reference is made to the explanations previously given in order to avoid repetition.

  • the housing 2 has a housing shell 3 as an outer enclosure, which here only exemplarily has a substantially round outer geometry.
  • the housing shell 3 extends in the vertical axis direction x and has, on its upper side as seen in the vertical axis direction x, a container 5 in which a volatile material 6, for example a fragrance and/or an active substance, to be delivered to the environment is accommodated.
  • a volatile material 6 for example a fragrance and/or an active substance
  • a reservoir 7 is arranged on the underside of the housing 2 opposite the container 5 in the vertical axis direction x as a further component of the housing 2, which will be described in more detail below and whose underside 8 is flat to form a flat standing surface.
  • a capillary element 4 is arranged in the interior of the housing 2 or the housing shell 3, as can be seen in particular from the joint view of Figures 2a and 2b, in such a way that the housing shell 3 completely surrounds or encloses the capillary element 4 here, for example, on the circumferential side and at a distance.
  • the housing shell 3 accommodates the container 5 at its upper side 9 approximately centrally, relative to the vertical axis direction x, so that the container 5 is arranged above the capillary element 4, relative to the use position of the dispenser 1 shown in Figures 1 , 2a and 2b and as viewed in the vertical axis direction x.
  • the container in the example case shown here has a container wall 10 on its underside facing the capillary element 4, which in cooperation with the capillary element 4 forms a discharge point 11 in a manner to be described, at which the volatile material 6 stored in the container 5 can be withdrawn from the container 5 and fed to the capillary element 4.
  • the capillary element 4 has a piercing element 12 at a free upper end section, which in turn is designed in the manner of a hollow needle having an inner cavity 13.
  • the container 5 is non-detachably connected to the housing 2 or housing shell 3, but can be moved in the direction of the piercing element 12. If the container 5 is now displaced towards the piercing element 12 from a (not shown) non-pierced starting position, as is only schematically indicated by the arrow 14 in Figure 2b, then the piercing element 12 pierces the container wall 10, as is schematically shown in Figure 2b, forming the discharge point 11.
  • the volatile material 6 can now flow out of the container 5 via the inner cavity 13 of the piercing element 12 after piercing the container wall 10.
  • the elastomer material of the container wall 10 is preferably designed in such a way that it tightly encloses the piercing element 12 on its outside when pierced and contracts again after removal of the piercing element 12 and preferably tightly seals the piercing point 11 .
  • the free end of the piercing element which forms a pointed end, can be asymmetrical in shape and have point areas 16, 17 projecting at different distances from the free end of the hollow needle.
  • the container 5 has a pressure compensation valve 18 on the side opposite the container wall 10 in the vertical axis direction x, by means of which air from the environment can flow into the container 5 for pressure compensation when the volatile material 6 flows out via the discharge point 11 , but via which pressure compensation valve 18 no volatile material 6 can flow out of the container 5.
  • this pressure compensation valve 18 is formed by a membrane 19 fulfilling these functions, which covers an air vent 20, here for example from the inside.
  • the piercing element 12 also has a widening wall section 21 which widens conically or funnel-shaped downwards and outwards in the direction of the vertical axis x and encloses a piercing element cavity 22.
  • the entire piercing element 12, i.e. the upper part of the piercing element 12, which is formed in the manner of a hollow needle, and the widening wall section 21 , which adjoins it at the bottom, are preferably formed here from a material which has no capillary effect, for example from a plastic material.

  • Figures 4, 5a and 5b show a second embodiment alternative to the first embodiment of Figures 1 , 2a, 2b and 3, which is described here only insofar as it differs from the first embodiment. Otherwise, the same parts are designated with the same reference signs.
  • a first difference of the second embodiment according to figures 4, 5a and 5b is that the container 5 here has a bottle-like shape with a bottle neck 49, wherein a sealing element 51 is inserted into the bottle neck opening 50.
  • This sealing element 51 has the same function as the container wall 10 of the first embodiment to be pierced with the piercing element 12.
  • the container 5 is designed here as an exchangeable refill and accordingly the container 5 can be detachably connected to the housing 2 or the upper side of the housing shell 3 in such a way that when the bottle neck 49 of the container 5, which has a corresponding thread, is screwed in, a downward displacement movement of the container 5 towards the piercing element 12 takes place and the piercing element 12 pierces the sealing element 51 after a defined displacement path in the volatile material delivery position shown in Figure 5b.
  • the volatile material 6 emerges from the container 5 in the same way as in the first embodiment and flows into the inner cavity 13 of the piercing element 12, which is otherwise essentially identical.
  • a final difference to the embodiment according to the first embodiment example of Figures 1 , 2a, 2b and 3 is that the collection room 42 in the second embodiment example is correspondingly adapted to the larger volume of the container 5 and is accordingly also larger than in the first embodiment example. Otherwise, the structure corresponds to that of the first embodiment, so that reference is made in this respect to the explanations there.
