Description

TECHNICAL FIELD

The present invention relates to a dispensing device for integration into a hygiene station for human hand hygiene, wherein hand towels, in particular cellulose hand towels for single use, can be dispensed by the dispensing device.

The present invention furthermore relates to a hygiene station for human hand hygiene, having at least one hygiene product dispensing device for dispensing at least one hand hygiene and/or handcare product and having at least one dispensing device as described above.

BACKGROUND

Dispensing devices for hand towels, for example in the form of paper hand towels for single use, also known as hand towel dispensers, are used in various environments such as restaurants, hotels, airports, industrial or office buildings, sanitary facilities, hospitals, filling stations, rest stops, etc. Such dispensing devices are already known in the prior art.

A washing area device is already known from DE 20 2007 000 842 U1, having a wash basin, having a hand towel dispenser for dispensing hand towels and having a disposal device for the hand towel, which is equipped with a shredding device for the hand towel.

Further, U.S. Pat. No. 6,082,664 A discloses an adapter for solid or coreless rolls of material which are dispensed in a roll dispenser, which may have slots defined on its side walls. The adapters may have a base body with a first side which is adjacent to the roll, and a second side which is adjacent to the side walls of the dispenser.

In addition, US 2010/078459 A1 relates to a dispenser for dispensing a sheet product, comprising a housing, a proximity sensor which is operative to detect a presence of a user's hand at a predetermined location in the vicinity of the dispenser, and a dispensing mechanism which is arranged inside the housing, wherein the dispensing mechanism comprises an electronic controller which is operably coupled to a drive motor that is operatively coupled to a feed roller in order to dispense the sheet product.

Moreover, WO 00/18284 A1 discloses a hand washing and drying apparatus comprising a washing and drying chamber having at least one access opening, which provides access for inserting at least one hand to be washed, a wash liquid dispenser in fluid communication with the interior of the washing and drying chamber for dispensing wash liquid within the washing and drying chamber, and a blow dryer which is in fluid communication with the interior of the washing and drying chamber for providing a directed supply of drying air within the washing and drying chamber.

Many of the users of these dispensing devices from the prior art have in the past been or will in the future be confronted with the challenge of the dispensing devices being defective and/or empty, that is to say no longer capable of dispensing paper hand towels.

SUMMARY

The object of the present invention is to advantageously develop a dispensing device of the type mentioned in the introduction, in particular so that the dispensing of hand towels may take place more reliably, more precisely and more securely.

This object is achieved according to the invention by a dispensing device having one or more of the features disclosed herein. Accordingly, a dispensing device for integration into a hygiene station for human hand hygiene is provided, wherein hand towels, in particular cellulose hand towels for single use, can be dispensed by the dispensing device; having at least one housing which has at least one dispensing opening for dispensing hand towels; having at least one first hand towel store which, in the mounted state, is received in the housing and which, in the original state, has a plurality of hand towels to be dispensed; having at least one second hand towel store which, in the mounted state, is received in the housing and which, in the original state, has a plurality of hand towels to be dispensed; and having at least one monitoring device for monitoring at least one state of the first hand towel store and/or of the second hand towel store and/or having at least one automatic change mechanism for automatically changing from dispensing hand towels from the first hand towel store to dispensing hand towels from the second hand towel store, or vice versa.

The invention is based on the underlying concept that by means of the automatic change mechanism for automatically changing the first hand towel store and the second hand towel store from one to the other and/or by the monitoring device, the dispensing security, or the operating security, of the dispensing device can be improved, or increased. Lastly, when the first hand towel store is used up, it may be replaced automatically with the second hand towel store. By these measures, downtimes due to paper dispensers incapable of dispensing can be reduced significantly. Furthermore, change or servicing intervals for the dispensing device may be extended, so that this has a positive effect on the overall cost structure. Furthermore, an increased dispensing security increases the satisfaction and well-being of the persons or customers using this device, from which the operators or proprietors of restaurants, hotels, airports, industrial or office buildings, sanitary facilities, hospitals, filling stations, rest stops, etc. additionally profit, and which represents a further quality feature of these devices. It may also be envisioned that the dispensing device has at least one contactless initialization sensor for contactlessly registering at least one wish to dispense at least one hand towel, which further improves the convenience of the dispensing device and in particular its hygiene properties. The two stores overall allow a supply for 2400 uses, so that an automatic change needs to take place at the earliest after about 1200 uses, which defines a threshold value for dispensed hand towels.

Moreover, the first hand towel store may be configured as a first endless roll and the second hand towel store may be configured as a second endless roll. Endless rolls in paper dispensers, or the present dispensing device, are standardized components that have been proven and developed for years, and which allow reliable dispensing of the hand towels. The operating and dispensing security of the dispensing device may therefore be improved by their use.

It may further be envisioned that the dispensing device is configured as at least one dispensing module for modular integration into the hygiene station. Such a design simplifies in particular the integration into a hygiene station, in the scope of which the dispensing device is conventionally used. In this case, defined interfaces such as installation dimensions and fastening points may be provided, which allow particularly simple mounting and integration. Alternatively, however, the dispensing device may be configured as a singular device, that is to say the dispensing device can be used independently of the hygiene station, for example by fastening it on a wall or coupling it to a corresponding holder or stand for mobile applications.

It is also conceivable that the housing has at least one drive mechanism, which is coupled to the first endless roll and/or the second endless roll. The drive mechanism simplifies the dispensing of the hand towels, since by this mechanism the hand towels are dispensed in such a way that a user no longer needs to pull thereon in order to dispense them further. The convenience in the use of the dispensing device for a user may therefore be improved further, and fewer misuses occur due to a user pulling the hand towels out incorrectly or too forcefully, or tearing them.

It is furthermore possible that the drive mechanism is configured as a rotary drive mechanism and is coupled to the first endless roll, the drive mechanism being adapted and configured in such a way that a hand towel can respectively be dispensed sequentially through the dispensing opening by respectively defined rotating of the first endless roll. The defined rotating, or the defined rotation, of the endless roll allows very precise and accurately defined dispensing of the individual hand towels. In this way, the size of the dispensed hand towel may be addressed better, in particular against the background of the conflict between a dispensed hand towel which is too large or too small, and an even better service may be provided for the user. Further, the dispensed length of the hand towels may be varied by a corresponding adjustment of the drive mechanism, so that it is thereby possible to respond even more precisely to different requirements for the hand towel size. Such requirements are associated, in particular, with the average hand size of the population in the respective country in which the dispensing device is used. Further requirements are, for example, usage habits and the gender of the users.

Furthermore, the monitoring device may have at least one counting unit, by which the number of hand towels already dispensed can be counted. The counting unit provides the dispensing device with a very simple but nevertheless effective and reliable tool, by which the number of hand towels already dispensed can be determined. The number of hand towels already dispensed from an endless roll is a crucial planning and control quantity for secure and reliable operation of the dispensing device. By the counting unit, further downtimes of the dispensing device may consequently be minimized and the procurement of new endless rolls can be initiated and optimized after a certain threshold value of dispensed hand towels has been exceeded.

It may likewise be envisioned that the counting unit has at least one counting sensor, two neighboring hand towels in the rolled state on the first endless roll being connected to one another by at least one perforation line, the perforation line having at least one numerical marking which can be registered by the counting sensor. A perforation line between two neighboring hand towels on the endless roll constitutes a reliable marking that constantly recurs each time individual hand towels are dispensed, and which can be registered and monitored very simply. It is therefore expedient for this perforation line to have a numerical marking or for a corresponding numerical marking, which can be registered very simply and reliably by the counting sensor, to be applied or perforated in the vicinity of (that is to say at a defined distance from) this perforation line. The perforation line, or tearing line, is in other words provided with a so-called counting point. The counting sensor is in this case configured as an optical counting sensor, for example an infrared counting sensor. Other optical counting sensors, such as photoelectric barriers, are likewise conceivable. Furthermore, the counting sensor is not restricted to optical counting sensors. In this context, touch-sensitive contact counting sensors or counting switches are conceivable. The hand towels are in this context perforated in such a way that the dispensed hand towel can be separated from the endless roll with a tearing force of about 20-50 grams. In comparison thereto, kitchen paper or household paper requires a tearing force of about 300 grams, while toilet paper requires a tearing force of about 100 grams. System punchcard, the separating line consists of punches and cuts. Punching likewise takes place for the infrared sensor that accurately controls the paper transport.

It is furthermore conceivable that the monitoring device has at least one position sensor and the perforation line has at least one position marking, which can be registered by the position sensor in such a way that the drive mechanism can be stopped in response to at least one registered position marking. The position marking is important because the drive mechanism in an automated fashion requires information as to when it needs to adjust the rotation of the roll, so that the position marking is very important for reliable and defined dispensing of individual hand towels. The position marking may be provided in the same way as the numerical marking and interact with the position sensor in the same way as the numerical marking interacts with the counting sensor, so that the technical effects and advantages in relation thereto are achieved. It is also conceivable for the position marking and the numerical marking respectively to be formed by a single common marking. Consequently, it is likewise conceivable that the position and counting sensor may be formed by a common sensor.

It is further possible that the dispensing device has at least one control and/or regulating unit or can be connected to at least one control and/or regulating unit, which can be connected to the monitoring device and to the automatic change mechanism, the control and/or regulating unit being adapted and configured, in response to a threshold value of dispensed hand towels counted by the counting unit, to control and/or regulate the automatic change mechanism in such a way that the automatic change mechanism changes the first hand towel store and the second hand towel store from one to the other. The advantage of this automatic change is the continuous supply of hand towels, particularly when the first endless roll is used up. No significant downtimes therefore occur for the dispensing device, since the automatic change takes place immediately after the dispensing of the last hand towel from the first endless roll and a new endless roll is ready for the further dispensing of hand towels after a short time.

In addition, the dispensing device may have at least one data transmission interface, in particular a radio data transmission interface, which is connected to the control and/or regulating unit, the control and/or regulating unit being adapted and configured in such a way that, in response to the counted threshold value of dispensed hand towels, it generates an order signal for a new hand towel store and transmits the order signal to the data transmission interface. The radio data transmission interface may, in particular, be configured as a WLAN interface and/or Bluetooth interface. In this way, the dispensing device may be connected to a backend server or a cloud service, which may in turn be connected to a relatively large number of further dispensing devices. By this structure, each individual dispensing device may be optimized insofar as, for example, software updates can be implemented automatically (keyword: “maintenance over the air”). Further, by this network structure and the interaction with artificial intelligence, weaknesses of a plurality of dispensing devices may be compared, evaluated and remedied substantially better since the amount of data available is increased. The ordering processes for new endless rolls may also be harmonized and thereby optimized. The operation of an individual dispensing device, as well as the overall group of dispensing devices, may therefore be simplified and optimized.

It may furthermore be envisioned that the first hand towel store in the original state is configured identically to the second hand towel store in the original state. By the identical configuration, scale effects may be achieved in the re-procurement or ordering of further endless rolls, or hand towel stores. Further, the change mechanism may be simplified since it does not need to be adjusted for merely one type of endless rolls. The structure and the functionality of the dispensing device are consequently simplified overall.

The present invention furthermore relates to a hygiene station for human hand hygiene; having at least one hygiene product dispensing device for dispensing at least one hand hygiene and/or handcare product; and having at least one dispensing device as explained above.

All structural and functional features related to the dispensing device according to the invention as described above, as well as its possible embodiments, may also be provided individually or in combination in the hygiene station according to the invention so that the advantages related thereto may be achieved.

DETAILED DESCRIPTION

FIG. 1 shows a schematic perspective representation of an exemplary embodiment of a dispensing device 10 according to the invention for integration into a hygiene station 12 for human hand hygiene, wherein the dispensing device 10 can dispense hand towels.

The dispensing device 10 is configured as a dispensing module for modular integration into the hygiene station 12.

The hand towels are configured as cellulose hand towels for single use.

The basis of the cellulose hand towels is intended to comprise ecologically friendly raw materials such as fast-growing bamboo or straw, or recycled paper, and the energy expenditure during production is intended to be low.

The dispensing device 10 has a box-like housing 14, which has at least one dispensing opening 14a for dispensing hand towels.

The box-like housing 14 has an open side, or filling side, which in the mounted state ready for operation is closed, for example, by means of a lid (not shown in FIG. 1), in which case the dispensing opening 14a may likewise be provided in the lid.

The dispensing device 10 further has a first hand towel store 16, which in the mounted state is received in the housing 14 and which in the original state has a plurality of hand towels to be dispensed.

The first hand towel store 16 in the original state is configured identically to the second hand towel store 18 in the original state.

The dispensing device 10 further has a second hand towel store 18, which in the mounted state is likewise received in the housing 14 and in the original state has a plurality of hand towels to be dispensed.

The first hand towel store 16 is configured as an endless roll 16a, so that the second hand towel store 18 is consequently configured as a second endless roll 18a.

The first endless roll 16a is arranged below the second endless roll 18a in the mounted state.

On its side inner faces that are turned toward one another, the housing 14 further respectively has two guide grooves 14b, 14c, 14d, 14e aligned or flush with one another.

The guide grooves 14b, 14c, 14d, 14e extend along the two side inner wall faces starting from the open side, or a filling side, toward the opposite closed side.

The guide grooves 14b, 14c, 14d, 14e also have a groove section, which is horizontal in the mounted state, and an inclined groove section following on therefrom, the inclination of which is aligned in the direction of a bottom region 14f of the housing 14 in the mounted state.

As is shown in FIG. 1, in the mounted state ready for operation, the two endless rolls 16a, 18a are guided in the respective inclined sections of the guide grooves 14b, 14c, 14d, 14e by means of corresponding roll stubs 16b, 16c, 18b, 18c, displaceably therein.

The dispensing device 10 further has a monitoring device 20 for monitoring a state of the first and second hand towel stores 16, 18.

Such a state relates in particular to the number of hand towels already dispensed from the first and second hand towel stores 16, 18, or the first and second endless rolls 16a, 18a.

Alternatively, it may be envisioned that the monitoring device 20 is intended for monitoring the state of the first or second hand towel store 16, 18.

The dispensing device 10 further has an automatic change mechanism 22 for automatically changing from dispensing hand towels from the first hand towel store to dispensing hand towels from the second hand towel store, or vice versa.

The housing 14 further has a drive mechanism, which is coupled to the first and second endless rolls.

In addition or alternatively, the drive mechanism 24 may be coupled to the first or second endless roll 16a, 18a.

The coupling to the two endless rolls 16a, 18a takes place according to FIG. 1 indirectly via a hand towel feed unit 26, which is connected or coupled to the respective endless roll 16a, 18a via an already unrolled section of hand towels and which is coupled to the drive mechanism 24.

In addition or alternatively, the coupling may take place directly via the respective two roll stubs 16b, 16c, 18b, 18c of the two endless rolls 16a, 18a, and for example a transmission or belt (not represented in FIG. 1).

The drive mechanism 24 is configured as a rotary drive mechanism and is coupled to the first endless roll.

The coupling in this case takes place as described above indirectly via the hand towel feed unit 26, which then delivers the hand towels that have been fed in to the dispensing opening 14a for their dispensing.

In the mounted state, the hand towel feed unit 26 is arranged in the bottom region 14f and in the vicinity of the dispensing opening 14a of the housing 14 and is fastened on a partially dual-level hand towel guide 28.

FIG. 2 shows a schematic lateral representation of the exemplary embodiment of the dispensing device 10 according to FIG. 1.

FIG. 2 represents the partially dual-level hand towel guide 28, the hand towel feed unit 26 and the drive mechanism 24 in more detail than FIG. 1.

The hand towel guide 28 is configured as an arcuate guide, which extends in the shape of an arc from the dispensing opening 14 to the first endless roll 16a and to the second endless roll 18a.

The hand towel guide 28 is configured as a structural unit and is subdivided into a first guide unit 30 and a second guide unit 32.

The first guide unit 30 consequently extends from the dispensing opening 14a to the first endless roll 16a and, by means of two arcuate guide rails 30a, 30b, forms a first guide channel 30c.

The first guide channel 30c opens out at the first endless roll 16a, where the first hand towel section or hand towel strip (indicated by corresponding arrows in FIG. 2) is inserted into the first guide channel 30c.

In the region of the outlet of the first guide channel 30c, a first so-called starter roll pair is furthermore arranged on the first guide rail 30a in order to improve the free running of the first endless roll 16a.

Inside the first guide channel 30c, the first hand towel section or hand towel strip extends as far as the dispensing opening 14a, the hand towel feed unit 26 being arranged in between in order to unroll the hand towel section or hand towel strip from the first endless roll 16a and dispense it in a defined way.

Accordingly, the second guide unit 32 extends from the dispensing opening 14a to the second endless roll 18a and, by means of two further arcuate guide rails 32a, 32b, forms a second guide channel 32c.

The second guide channel 32c opens out at the second endless roll 16a, where the second hand towel section or hand towel strip (also indicated by corresponding arrows in FIG. 2) is inserted into the second guide channel 32c.

In the region of the outlet of the second guide channel 32c, a second so-called starter roll pair is furthermore arranged on the second guide rail 32a in order to improve the free running of the second endless roll 18a.

Inside the second guide channel 30c, the hand towel section or hand towel strip extends as far as the dispensing opening 14a, the hand towel feed unit 26 being arranged in between in order to unroll the hand towel section or hand towel strip from the second endless roll 18a and dispense it in a defined way.

The hand towel feed unit 26 is formed by a total of four guide rollers 26a, 26b, 26c, 26d, which are respectively assigned in pairs on the one hand to the first guide channel 30c and correspondingly to the second guide channel 32c.

According to FIG. 2, the two guide roller pairs 26a, 26b, 26c, 26d assigned in this way are respectively in contact inside the first and second guide channels 30c, 32c with the hand towel section or hand towel strip to be dispensed.

A rotational movement of the guide roller pairs 26a, 26b, 26c, 26d is therefore converted into a corresponding rotational movement of the first and second endless rolls 16a, 18a and a corresponding defined linear dispensing movement of an individual paper hand towel at the dispensing opening 14a.

A guide roller pair 26a, 26b, 26c, 26d is on the one hand respectively formed by a driven guide roller 26a, 26c, which is coupled to the drive mechanism 24 via a transmission.

Other types of this coupling, for example a belt drive or a chain drive, are likewise conceivable.

Further, a guide roller pair 26a, 26b, 26c, 26d is on the other hand respectively formed by a nondriven guide roller 26a, 26c, which are coupled to the guide unit 30 via a spring mechanism.

The function of the dispensing device 10 according to FIGS. 1 and 2 may now be described as follows:

According to FIGS. 1 and 2, the drive mechanism 24 is configured as a rotary drive mechanism and is coupled to the first endless roll 16a via the hand towel feed unit 26 and the corresponding hand towel strip.

The drive mechanism 24 is adapted and configured in such a way that a hand towel can respectively be dispensed sequentially through the dispensing opening 14a by respectively defined rotating of the first endless roll 16a.

For the defined rotation of the first endless roll 16a, the feed unit 26 may in turn be correspondingly driven via the drive mechanism 24.

This control may, in particular, take place on the basis of rotational speed or rotational angle.

The hand towel dispensing may be monitored by means of the monitoring device 20 (cf. FIG. 2), which monitors the state of the first and second endless rolls 16a, 18a.

Such a state relates in particular to the number of hand towels already dispensed from the first endless roll 16a.

Such a state also relates to the number of hand towels already dispensed from the second endless roll 18a, if the latter is currently being used for dispensing hand towels.

In order to determine the number of hand towels already dispensed from the first or second endless roll 16a, 18a, the monitoring device 20 has a counting unit 20a by which the number of hand towels already dispensed can be counted.

The counting unit 20a in turn has a counting sensor, by means of which the number of dispensed hand towels can be registered.

For this purpose, two neighboring hand towels inside the hand towel strip or in the rolled state on the first endless roll 16a have a perforation line by which they are connected to one another, the perforation line in turn having a numerical marking which can be registered by the counting sensor.

The monitoring device 20 furthermore has a position sensor 20b.

Accordingly, the perforation line further contains a position marking, which can be registered by the position sensor 20b in such a way that the drive mechanism 24 can be stopped in response to a registered position marking.

For this purpose, the dispensing device 10 further has a control and regulating unit (not shown).

In addition or alternatively, the dispensing device 10 may be connected by cables or wirelessly to a control and regulating unit.

Further, the control and regulating unit is also connected to the monitoring device 20 and to the drive mechanism 24, and can drive or regulate these as described above.

The control and regulating unit continuously evaluates the number of hand towels dispensed from the first endless roll 16a, and compares this with a stored threshold value.

As soon as the number of dispensed hand towels has exceeded this threshold, the control and regulating unit controls or regulates the automatic change mechanism 22, to which it is likewise connected.

For this purpose, the automatic change mechanism 22 decouples the drive mechanism 24 from the guide roller pair 26a, 26b that is assigned to the first guide channel 30c, so that no further hand towels can be unrolled from the first endless roll 16a.

Subsequent to this, the automatic change mechanism 22 couples the drive mechanism 24 to the guide roller pair 26c, 26d that is assigned to the second guide channel 32c.

The control or regulating is therefore carried out in such a way that the change mechanism 22 changes from dispensing hand towels from the first hand towel store or first endless roll 16a to dispensing hand towels from the second hand towel store or second endless roll 18a.

Further hand towels can then correspondingly be unrolled sequentially from the second endless roll 18a, and monitored as described above in connection with the first endless roll 16a.

The dispensing device 10 furthermore has a data transmission interface, which is likewise connected to the control and regulating unit.

The data transmission interface is configured as a radio data transmission interface.

The data transmission interface may, in particular, be configured as a WLAN and/or Bluetooth interface.

The control and regulating unit is furthermore adapted and configured in such a way that, in response to the counted threshold value, it generates an order signal for a new hand towel store or a new endless roll 16a, 18a and transmits the order signal to the data transmission interface.

By the configuration as a radio data transmission interface, the dispensing device 10 may in addition be connected to a backend server or a cloud service, which may in turn be connected to a relatively large number of further dispensing devices.

By this structure, each individual dispensing device (not shown) may be optimized insofar as, for example, software updates can be implemented automatically (keyword: “maintenance over the air”).

FIG. 3 shows a further schematic lateral representation of the exemplary embodiment of the dispensing device 10 according to FIG. 1.

This figure shows the case of a problem with the hand towel delivery, the first endless roll 16a additionally having been removed here.

In order to remedy this problem, the hand towel guide 28 may be partially tilted out so as to ensure better access for correcting the problem.

For this purpose, the hand towel guide 28 has a hinge 28a, via which it is rotatably coupled to the two side inner walls of the housing 14.

For the release, the hand towel guide 28 additionally has a release lever 34, by means of which the hand towel guide 28 can be locked or released.

As may likewise be seen in FIG. 3, this arrangement also allows the paper web of the second endless roll 18a to be accessible by tilting the hand towel guide 28 upward. A “paper jam” or another problem may thus be corrected easily.

FIG. 4 shows a schematic perspective representation of a driven guide roller 26a, 26c of the exemplary embodiment of the exemplary embodiment of the dispensing device 10 according to FIG. 1.

The guide roller 26a, 26c is formed by a hollow-cylindrical aluminum body, the lateral face of which has a rubber coating.

The rubber coating may optionally be fully continuous radially and axially.

Alternatively, the guide roller 26a, 26c may also have a plurality of continuous rubber rings axially separated from one another.

Fitted at the respective two ends of the hollow-cylindrical aluminum body, there are two axle stubs by means of which the guide roller 26a, 26c can be mounted on the housing side walls.

The guide roller 26a, 26c also has a gearwheel at one end, via which it can be coupled to the drive mechanism 24 (cf. for example FIG. 1).

FIG. 5 shows a schematic cross-sectional representation of the driven guide roller according to FIG. 4.

The inner connecting regions at the two respective ends of the hollow-cylindrical aluminum body with the two fitted axle stubs are represented in more detail therein.

For the mutual axial and radial securing, the two axle stubs are respectively fastened via a pin to the hollow-cylindrical aluminum body.

The gearwheel is likewise connected, or coupled, via a pin to one of the two axle stubs for mutual axial and radial securing.

FIG. 6 shows a schematic cross-sectional representation of a nondriven guide roller 26b, 26d of the exemplary embodiment of the exemplary embodiment of the dispensing device according to FIG. 1.

The nondriven guide roller 26b, 26d is substantially equivalent to the driven guide roller 26a, 26c according to FIGS. 4 and 5, the essential difference being however that the nondriven guide roller 26b, 26d does not have a rubber layer.

FIG. 7 shows a schematic perspective representation of an endless roll 16a, 18a of the exemplary embodiment of the dispensing device according to FIG. 1.

The endless roll 16a, 18a has a hollow cylindrical cardboard core, on which an endless strip of perforated single-use hand towels is wound so that an endless roll 16a, 18a with its final diameter is formed.

Fitted loosely at the two ends of the endless roll 16a, 18a, there are respectively two roll stubs 16b, 16c, 18b, 18c by which the endless rolls 16a, 18a can be guided displaceably in the corresponding guide grooves 14b, 14c, 14d, 14e in the side inner faces, in order to compensate for the diameter reduction during the unrolling.

The displacement takes place automatically by the force of gravity because of the inclination of the guide grooves 14b, 14c, 14d, 14e.

FIG. 8 shows a schematic perspective representation of an exemplary embodiment of a hygiene station 12 according to the invention for human hand hygiene.

The hygiene station 12 has a dispensing device 10 as described above.

The hygiene station 12 may further have a reception container 12a with a reception volume for used hand towels and a reception opening 12b for introducing used hand towels into the reception container 12a.

It may furthermore be envisioned that the hygiene station 12 has a shredding device in the region of the reception container 12a for shredding used hand towels, which in the mounted state is arranged between the reception opening 12b and the reception volume.

The hygiene station 12 further has a hygiene product dispensing device 12c for dispensing a hand hygiene and handcare product.

The hand hygiene product may, in particular, be in the form of a disinfectant.

In addition or alternatively, the hygiene product dispensing device may be adapted to dispense a hand hygiene or handcare product.

According to FIG. 8, the hygiene station 12 is configured as a hygiene station 12 fastened rigidly on a wall.

Alternatively, the hygiene station 12 may also be configured as a mobile hygiene station 12 and be coupled to a corresponding roll stand, roll frame or roll-guided holder.
