The disclosure pertains to a bracket for mounting of a dispenser on a vertical wall, the bracket comprising a rear surface, a front surface, an upper edge, a lower edge and two side edges, each side edge extending between the upper edge and the lower edge. The bracket has a width direction X, a height direction Y perpendicular to the width direction and a thickness direction Z perpendicular to both the width direction and the height direction. The bracket further comprises a sensor seat, a wall connection arrangement and a dispenser connection arrangement. The dispenser connection arrangement comprises one or more dispenser connection members. The disclosure further pertains to a dispenser arrangement comprising a bracket and a dispenser being connectable to the bracket and having a compartment for containing consumable hygienic material arranged in a dispenser body.

A dispenser system comprising a dispenser arrangement and a sensor unit are also disclosed herein.

BACKGROUND

The dispensers as disclosed herein are wall hung dispensers, i.e. dispensers which are mounted on a generally vertical wall. The dispensers are dispensers for consumable hygiene products, for instance different types of wiping material such as toilet paper, hand towels and cleaning towels as well as dispensers for liquids such as liquid soap, lotion or disinfectant.

The fill level of the consumer product left in a dispenser may be monitored manually by cleaning staff. Manual checking of the fill level may be carried out by opening the dispenser or by determining the level through an inspection window arranged in the dispenser wall. The dispenser is refilled when the check reveals that the dispenser is empty or the content level is so low that replenishing is needed. Manual monitoring is time-consuming and may sometimes prove inadequate as it does not compensate for unexpected sudden changes in an expected consumption rate, e.g. when the consumption rate for some reason deviates from a previously established average consumption rate.

In order to remedy the shortcomings of manually monitored dispensers, automatic monitoring systems have been developed. WO2014/031045 A1 discloses a fill level monitoring system comprising a dispenser which is arranged to be mounted on a substantially vertical wall. A load cell is provided for monitoring the fill level of a consumer product which is contained in the dispenser. The dispenser is arranged to be mounted on the vertical wall by means of an upper fastening arrangement and a lower fastening arrangement, the upper fastening arrangement being provided with the load cell. The load cell is arranged to mainly sense forces acting in the horizontal direction when the dispenser is mounted on the wall. The lower and the upper fastening arrangements may be configured to enable displacement of a rear wall of the upper fastening arrangement in a direction perpendicular to the rear wall in response to varying weight of the consumer product and to enable the dispenser to rotate around the lower fastening arrangement.

DE10047986A1 discloses an automatic detection system wherein several dispensers comprising sensors are connected to a display unit indicating the fill level. Optical sensors and weight sensors are used in the automatic detection system to determine the level of consumer products in the dispensers, and a signal is provided by the display unit when the level of consumer products is low. Thereby, it simplifies the monitoring of consumer product levels in the dispensers. DE10047986A1 discloses a general system but does not further disclose how the sensors may be arranged or configured in/on the dispenser units in order to offer accurate and reliable measurements or to avoid tampering.

US5918197A discloses a monitor for collecting data on consumer consumption of e.g. stacked paper towels during a limited testing period. The monitor comprises a working surface, a load cell and a recorder arranged in a housing. The dispenser from which the consumption is being monitored is placed on the working surface. A variation in weight due to consumption of the consumer products during the test period is recorded. The monitor is not integrated into the dispenser and is therefore mostly suitable for occasional fill level tests, e.g. for establishing an average consumption rate. Also, it is suitable for being arranged underneath the dispensers because the load cell is substantially sensitive to vertical forces exerted upon the working surface under the influence of the weight of the consumer products.

Although automatic monitoring systems have benefits over the non-automatic systems, in some instances dispensers requiring manual monitoring or checking of the fill-level may be preferred as they are comparatively less expensive and less technically complicated with fewer parts than automatic monitoring systems.

The dispensers are commonly attached to the wall using a bracket which is pre-mounted on the wall where after the dispenser is fastened to the bracket. The brackets are adapted for fastening of a particular type of dispenser which means that the brackets need to be provided in many different varieties. Accordingly, there is a need for reducing the number of different brackets which have to be produced and which have to be matched to a specific type of dispenser. Hence, there is a need for a bracket which may be used for a dispenser regardless of whether the dispenser has equipment for monitoring fill level or is a dispenser without such equipment.

SUMMARY

The above needs may be met with a bracket for mounting a dispenser on a vertical wall in accordance with claim 1 , a dispenser arrangement in accordance with claim 5 and a dispenser system in accordance with claim 12. Variations of the disclosure are set out in the dependent claims.

Disclosed herein is a bracket for mounting a dispenser on a vertical wall. The bracket comprises a rear surface, a front surface, an upper edge, a lower edge and two side edges, each side edge extending between the upper edge and the lower edge. The bracket has a width direction X, a height direction Y perpendicular to the width direction and a thickness direction Z perpendicular to both the width direction and the height direction. The bracket comprises a wall connection arrangement and a dispenser connection arrangement. The dispenser connection arrangement comprises one or more dispenser connection members. The bracket further comprises a sensor seat which is configured to be accessible for mounting of a sensor unit in the sensor seat after disablement of the one or more dispenser connection members.

As used herein, a vertical wall should be understood in a broad sense and may be any type of vertical wall such as an inner or outer wall of a building or a wall on a structure inside or outside a building such as a cabinet wall or a free-standing wall, such as a wall on a hygiene stand.

The bracket as disclosed herein may comprise two or more sensor seats for mounting two or more sensor units in the bracket.

The bracket as disclosed herein may be used as a standard bracket for attaching a dispenser with or without an automatic fill-level monitoring system including a sensor unit. The bracket may be used when replacing a dispenser without an automatic fill-level monitoring system with a dispenser comprising an automatic fill-level monitoring system. Furthermore, the bracket may allow post-mounting of a sensor unit to equip an existing dispenser with an automatic fill-level monitoring system.

Disablement of the one or more dispenser connection members implies making the one or more dispenser connection members non-functional for connecting a dispenser to the bracket by means of the dispenser connection members. Disablement of the one or more dispenser connection members may be performed by partial or complete removal of the dispenser connection members or by inactivation of the dispenser connection members. Inactivation may involve destroying or deforming the dispenser connection members e.g. by moving or bending the dispenser connection members. The bracket may be configured such that the dispenser connection members block access to the sensor seat before disablement of the dispenser connection members, implying that a sensor unit can be mounted in the sensor seat only after disablement of the one or more dispenser connection members.

Disablement of the one or more dispenser connection members may be fully or partly effectuated separately from the process of mounting of the sensor unit in the sensor seat, or may be effected simultaneously with mounting of the sensor unit in the sensor seat. In the latter case, insertion of the sensor unit in the sensor seat, causes disablement of the one or more dispenser connection members. When the sensor unit is mounted in place in the sensor seat, the dispenser connection members are in a disabled state, either by having been disabled before mounting of the sensor unit or by having been disabled as a result of pushing the sensor unit into the sensor seat.

The one or more dispenser connection members may be configured to restrict relative movement between the bracket and a dispenser in the thickness direction Z of the bracket, the one or more dispenser connection members preferably also being arranged to restrict relative movement between the bracket and a dispenser in the width direction X of the bracket and/or in the height direction Y of the bracket. Accordingly, when a dispenser is mounted on the bracket, movement between the bracket and a dispenser may be restricted perpendicular to the wall on which the bracket and the dispenser are mounted and may also be restricted in the vertical and horizontal directions parallel to the wall.

Restriction of the movement between the dispenser and the wall implies that a small play may be allowed in the connections such as a play in the order of 1 millimetre or less or that relative movement between the bracket and the dispenser is completely inhibited in the connections. A connection in which movement between the bracket and the dispenser is restricted or completely inhibited in all three directions, X, Y, Z is referred to herein as being a rigid connection.

The one or more dispenser connection member(s) as disclosed herein may comprise a spring element, such as two, three, four, or more spring elements.

The dispenser connection arrangement in a bracket as disclosed herein may comprise a pair of first spring elements being configured for restricting relative movement between the bracket and a dispenser in the width direction X of the bracket and a pair of second spring elements being configured for restricting relative movement between the bracket and a dispenser in the height direction Y of the bracket and in the thickness direction Z of the bracket.

Disclosed herein is further a dispenser arrangement comprising a bracket as disclosed herein and a dispenser, the dispenser comprising a dispenser body having a compartment for containing consumable hygienic material arranged in the dispenser body and a dispensing arrangement for dispensing consumable hygienic material from the compartment in the dispenser body, wherein the dispenser comprises a bracket connection arrangement, the bracket connection arrangement being configured to interact with the dispenser connection arrangement on the bracket, to form a direct connection between the dispenser and the bracket. As used herein, a direct connection between two components is a connection where the components are in direct contact with each other. An indirect connection is a connection where an intermediate component or element is present between the components at the location of the connection.

The connection between the bracket connection arrangement on the dispenser and the dispenser connection arrangement on the bracket may be a snap-in connection. Other conceivable types of connections are slide-in connections, plug-in connections, screw connections, etc. Connections which may be made out manually, without using tools are generally preferred. It may also be preferred that the dispenser connection members on the bracket are arranged to cooperate with corresponding bracket connection members on the dispenser such that the dispenser connection members and the bracket connection members lock together when the bracket connection arrangement is connected with the dispenser connection arrangement. An interlocking connection may be achieved e.g. by a snap-in connection.

The connection between the bracket connection arrangement on the dispenser and the dispenser connection arrangement on the bracket may be a rigid connection as defined herein.

The dispenser in a dispenser arrangement as disclosed herein has an upper part and a lower part. The bracket connection arrangement on the dispenser may be arranged at the upper part of the dispenser. The dispenser may further comprise a wall connection arrangement at the lower part of the dispenser.

The dispenser as disclosed herein may be a dispenser for wiping material. Examples of different types of wiping material include toilet paper, hand towels and cleaning towels. The dispenser may be a dispenser for dispensing wiping material in any form such as roll form paper or stacks of wipes in sheet form. The wiping material may be any type of wiping material as known in the art such as paper, nonwoven or hybrid nonwoven/paper materials. Sheet form wipes may be interfolded to create a succession of wipes being fed out through a dispensing opening. Furthermore, dispensers for roll-form paper may be center feed or peripheral feed. The dispensers may be manually or automatically operated.

The dispenser as disclosed herein may be a liquid dispenser, such as a dispenser for soap, lotion, disinfectant, etc. The dispenser may include a pump, and may be manually or automatically operated. Disclosed herein is also a dispenser system comprising a dispenser arrangement as disclosed herein, the dispenser system further comprising a sensor unit, the sensor unit being configured to be applied in the sensor seat of the bracket. As disclosed herein, the bracket is configured to allow application of the sensor unit after disablement of the one or more dispenser connection member which is arranged in the bracket and may be configured to allow application of the sensor unit in the sensor seat only after the one or more dispenser connection members arranged in the bracket have been disabled.

Disablement of the one or more dispenser connection members may be made in a separate disablement step, e.g. by removing or deforming the dispenser connection members before inserting the sensor unit in the sensor seat in the bracket. Such disablement may be carried out manually or by using a tool, such as a pair of tongs. Alternatively, application of the sensor unit in the sensor seat may cause the disablement of the one or more dispenser connection members. It may be preferred that the one or more dispenser connection members are disabled simultaneously with application of the sensor unit in the sensor seat, e.g. by the sensor unit acting to disable the one or more dispenser connection members while it is being pushed into the sensor seat. The bracket may be configured such that the forces applied to the sensor unit when pushing the sensor unit into the sensor seat causes the one or more dispenser connection members e.g. to be pushed aside, broken off, or to be otherwise deformed to an extent where the one or more dispenser connection members can no longer function as connection members for connecting a dispenser to the bracket.

In case a dispenser has been mounted to the bracket before disablement of the one or more dispenser connection members, disablement of the one or more dispenser connection members may involve decoupling of the dispenser from the bracket. It may be preferred that when disablement results from application of the sensor unit in the sensor seat, an indirect connection between the bracket and the dispenser is established by means of a direct connection between the sensor unit and the dispenser being created as the sensor unit is applied in the sensor seat. The indirect connection between the dispenser and the bracket will thereby replace the broken direct connection between the dispenser and the bracket.

The disablement of the one or more dispenser connection members may be reversible, e.g. when the one or more dispenser connection members are spring loaded members which are disabled by pushing or flexing the spring loaded members out of a position where they may serve to connect the bracket with a dispenser. Such dispenser connection members may be restored to an enabled position upon removal of a sensor unit which has been applied in the sensor seat. When the sensor unit is removed from the sensor seat, the spring loaded dispenser connection members will simply spring back to the enabled position where they may again serve to form a direct connection between a dispenser and the bracket. Another non-limiting example of dispenser connection members which may be reversibly disabled are removable dispenser connection members which can be reinserted in the bracket if direct connection between the bracket and a dispenser is desired.

Alternatively, disablement of the one or more dispenser connection members may be irreversible, e.g. when the one or more dispenser connection members are disabled by being broken off or irreversibly deformed. The sensor unit may be applied in the sensor seat by means of one or more snap-in connections and/or slide-in connections.

The sensor unit may comprise a weight sensor which is configured to sense a weight of consumable hygienic material in the compartment in the dispenser body. The weight sensor may comprise one or more load cells, such as two load cells. Power supply to the weight sensor may be provided by a battery or batteries arranged in the sensor unit. Alternatively, a battery or batteries may be arranged separate from the sensor unit in any suitable part of the dispenser or the bracket. External power supply to the sensor unit is also conceivable for the automatic fill-level monitoring arrangements as disclosed herein. As disclosed herein, the dispenser may be connected only indirectly to the bracket via the sensor unit when the dispenser is mounted on the bracket with the sensor unit applied in the sensor seat and with the one or more dispenser connection members being disabled. The direct connection between the dispenser and the sensor unit, allows a sensor to register changes in weight of the dispenser and/or movements in the dispenser which movements may be translated into a change in weight and thereby into a change in fill level in the dispenser.

Indirect determination of fill level by determining the weight of the contents in the dispenser based on movements in the dispenser may be carried out as disclosed in

WO2014/031045A1 which is hereby incorporated in full by reference. WO2014/031045 A1 discloses the use of a load cell sensor to sense displacement of a rear wall of the dispenser generally horizontally and perpendicular to the rear wall. A change in tilting of the rear wall of the dispenser which is caused by a change in force from the contents in the dispenser translates into a change in weight of the contents in the dispenser and thereby a change in fill level. The fill level monitoring system may comprise an electronic fill level indicator. The electronic fill level indicator may be arranged on the dispenser and/or on a separate control unit. Light emitting diodes, liquid crystal display, or similar may be used to indicate the current fill level for cleaning staff and users of the dispenser. Such indicators simplify the refilling procedure for cleaning staff, and indicate the consumer product level to users of the dispenser.

DETAILED DESCRIPTION

Different aspects of the present disclosure will be described more fully hereinafter with reference to the enclosed drawings. However, the brackets, dispenser arrangements and dispenser systems disclosed herein can be realized in many different forms and should not be construed as being limited to the aspects set forth herein. It should be understood, that although the dispensers described below are paper towel dispensers, the claimed invention is equally applicable to any type of dispenser for consumable hygiene products, such as dispensers for toilet paper or other types of wiping material, as well as dispensers for liquids such as liquid soap, lotion or disinfectant.

The dispenser arrangement 1 which is shown in Fig. 1 when mounted on a vertical wall 4, comprises a dispenser 2 comprising a dispenser body 21 having a compartment 22 for containing a stack of hand towels arranged in the dispenser body 21 and a dispensing opening 23 arranged at a lower part 24 of the dispenser, vertically opposite an upper part 25 of the dispenser 2. Hand towels (not shown) which are contained in the dispenser body are dispensed through the dispensing opening, by a user gripping a hand towel which is partially exposed in the dispensing opening 23 and drawing out the hand towel from the dispensing opening. The hand towels may be individually stacked sheets of material, interfolded sheets of material, zig-zag folded continuous webs, etc. as known in the art. As disclosed herein, alternative dispensing options involve dispensing of roll-form material either from a centre part of a roll of wiping material or from a peripheral part of a roll of wiping material. When dispensing material from a centre part of a roll of wiping material, the dispensing opening may either be placed at the top or the bottom of the dispenser, if the dispenser body is adapted for accommodating a roll standing on one of its end surfaces or may be placed in a front wall of the dispenser body if the dispenser body is adapted for accommodating a roll with the end surfaces of the roll arranged parallel to front and rear walls of the dispenser body.

The dispenser may be manually operated as the dispenser shown in Fig. 1 or may be provided with an automated feed-out system as known in the art. Dispensers for liquids such as liquid soap, etc. are generally provided with a dispensing opening at the lower end of the dispenser and are usually provided with a manually or automatically operated pump for feeding out the liquid through the dispensing opening.

The bracket 3 which is shown in Fig. 2 has a front surface 31 , a rear surface 32, an upper edge 33, a lower edge 34 and two side edges 35, each of the side edges 35 extending between the upper edge 33 and the lower edge 34. The bracket has a width direction X, a height direction Y perpendicular to the width direction and a thickness direction Z perpendicular to both the width direction and the height direction. When the bracket is mounted on a vertical wall, the width direction X is aligned with the horizontal direction of the wall, the height direction Y is aligned with the vertical direction of the wall and the thickness direction Z is perpendicular to the plane of the wall. The bracket 3 comprises a wall connection arrangement 36 which is shown as two screw- holes in Fig. 2. Thus, the bracket 3 is intended to be mounted on a vertical wall by means of screws passing through the screw holes. The bracket 3 further comprises a dispenser connection arrangement 37a, 37b. In the bracket 3 which is shown in the figures, the dispenser connection arrangement 37a, 37b is made up of a pair of first dispenser connection members 37a and a pair of second dispenser connection members 37b, each of the dispenser connection members 37a, 37b being in the form of leaf springs.

The bracket 3 further comprises a sensor seat 38. As disclosed herein, the sensor seat 38 is configured to be accessible for mounting of a sensor unit in the sensor seat with the pairs of first and second dispenser connection members 37a, 37b being disabled. A pair of sensor coupling members 39 in the form of recesses is arranged at the lower edge 34 of the bracket 3. The sensor coupling members 39 are configured to interact with corresponding coupling members on the sensor unit to form a connection between the bracket and the sensor unit.

Fig. 3 shows the Fig. 1 dispenser 2 with the front part of the dispenser body 21 removed and the rear wall 26 of the dispenser body 21 exposed to the viewer. The bracket 3 is attached to the wall 4 which is located behind the bracket 3 and the rear wall 26 of the dispenser body 21 . The upper part 25 of the rear wall 26 of the dispenser body 21 is directly connected to the bracket 3 by means of the dispenser connection members 37a, 37b which are shown in Fig. 2. In addition, the lower part 24 of the dispenser 2 is directly connected to the wall 4 by means of a lower wall connection arrangement in the rear wall 26 of the dispenser body 21 . The lower wall connection arrangement may be one or more screw holes, an adhesive attachment, etc.

With reference now to Figs. 4 and 5, there is shown a sensor unit 5. The sensor unit 5 is shown in Fig. 4 from the front surface 51 and is shown in Fig. 5 from the rear surface 52. When the sensor unit 5 is mounted in a bracket 3 which is attached to a vertical wall 4 as shown in Fig. 3, the front surface 51 of the sensor unit 5 is the surface which will be facing away from the vertical wall 4 and the rear surface 52 of the sensor unit 5 is the surface which will be facing towards the vertical wall 4. As can be seen in Fig. 5, the sensor unit 5 is provided with two load cells 53 placed at each end of the sensor unit 5 as seen in the width direction X of the sensor unit 5. A battery compartment 54 is located between the load cells 53.

Each of the load cells 53 are provided with contact members 55 which are configured for contacting the respective load cell 53 and to provide a defined contact area between the dispenser 2 and the sensor unit 5. The contact members 55 on the load cells 53 are arranged on pivotable plates 56 which can be tilted in a direction perpendicular to the vertical wall 4 on which the dispenser 2 is mounted. Thereby, the load cells 53 may register the force acting on the connections between the dispenser 2 and the sensor unit 5, the force being directly dependent on the weight of the contents in the dispenser which can be translated to a measure of the fill level of the dispenser. The degree of movement/tilting of the dispenser is directly dependent on the gravitational force acting on the dispenser which, in turn, is dependent on the amount of consumable hygienic product which is present in the dispenser. The sensor unit 5 further comprise a pair of bracket coupling members 57 in the form of tabs which are configured to be inserted into the corresponding sensor coupling members 39 in the form of recesses which are arranged in the bracket 3. It is to be understood that the sensor coupling members and the bracket coupling members may be configured differently from the non-limiting example shown in the figures and/or that they may be placed at other locations. The coupling members are optional to the bracket/sensor unit combinations as disclosed herein as for some applications it may be sufficient that the shape of the sensor unit is adapted to the shape of the sensor seat such that the sensor unit is securely held in the sensor seat by means of the fit between the sensor unit and the sensor seat. Furthermore, if a coupling arrangement is provided it may be sufficient to use a single connection between the sensor unit 5 and the bracket 3 or more than two connections can be used. The connection or connections between the sensor unit and the bracket may comprise or consist of one or more snap-in connections.

Application of the sensor unit 5 into the sensor seat 38 will now be described with reference to Figs. 2 and 4-7. The sensor unit 5 is shown in Fig. 6 in the process of being inserted into the bracket 3, the bracket 3 being shown from the front surface 31 . When inserting the sensor unit 5 into the bracket 3, the bracket coupling members 57 on the sensor unit 5 are inserted into the corresponding sensor coupling members 39 which are arranged in the bracket 3. Thereby, a hinge connection is formed by the bracket coupling members 57 and the sensor coupling members 39 about which hinge connection the sensor unit 5 may be tilted into position in the sensor seat 38. Fig. 7 shows the bracket 3 from the rear, wall-facing side 3 and with a dispenser 2 with the rear dispenser wall 26 being attached to the bracket 3 by means of connections between the bracket connection arrangement 27a, 27b on the dispenser 2 and the dispenser connection arrangement 37a, 37b on the bracket 3. The bracket connection arrangement is constituted by a pair of first bracket connection members 27a which are arranged to cooperate with the pair of first dispenser connection members 37a on the bracket 3 to form first connections between the dispenser 2 and the bracket 3, and a pair of second bracket connection members 27b which are arranged to cooperate with the pair of second dispenser connection members 37b on the bracket 3 to form second connections between the dispenser 2 and the bracket 3. Fig. 7 shows the dispenser 2 and the bracket 3 before the sensor unit 5 has been pushed into the bracket seat 38 and with both the first and the second connections between the dispenser 2 and the bracket 3 fully operative.

The first dispenser connection members 37a are in the form of leaf springs which are arranged to flex in a direction towards the side edges 35 of the bracket 3 as indicated by the arrows A. An outer, free end of each first dispenser connection member 37a is provided with a hook-shaped dispenser engagement element 37a’.

The first bracket connection members 27a on the dispenser 2 are in the form of flanges which fit in the dispenser engagement elements 37a’ at the ends of the first dispenser connection members 37a when the dispenser 2 is connected with the bracket 3 as shown in Fig. 7. The connections between the first bracket connection members 27a and the first dispenser connection members 37a restrict relative movement between the bracket 3 and a dispenser 2 in the thickness direction Z of the bracket 3 as well as in the height direction Y of the bracket 3.

The second dispenser connection members 37b, are in the form of leaf springs which are arranged to flex in the thickness direction Z of the bracket 3, i. e in a direction perpendicular to the plane of a wall on which the bracket is mounted. The second dispenser connection members 37b cooperate with the corresponding second bracket connection members 27b on the dispenser to form a connection which restricts movement between the dispenser 2 and the bracket in the width direction X and in the thickness direction Z of the bracket. The second bracket connection members 27b are constituted by abutment edges which bear against outer side edges of the second dispenser connection members 37b when in the connected configuration as shown in Fig. 7.

By means of the restrictions in relative movement between the dispenser and the bracket provided by the connection members 27a, 27b and 37a, 37b, the connection between the bracket connection arrangement 27a, 27b on the dispenser 2 and the dispenser connection arrangement 37a, 37b on the bracket 3 is a rigid connection as defined herein.

When the sensor unit 5 is applied in the sensor seat 38, as shown in Fig. 6, the connections between the bracket 3 and the dispenser 2 are at the same time decoupled. Accordingly, mounting of the sensor unit 5 in the sensor seat, simultaneously effects disablement of the dispenser connection members 37a, 37b. Tilting and pressing the sensor unit 5 into the sensor seat 38 in the direction of the arrow B will cause the first dispenser connection members 37a on the bracket 3 to be deflected in the direction of the arrows A in Fig. 7, thereby disengaging the first bracket connection members 27a on the dispenser 2 from the dispenser engagement elements 37a’ on the bracket. The second dispenser connection members 37b on the bracket 3 will be pushed in the thickness direction Z, inwards towards the wall on which the dispenser is hung until the second dispenser connection members 37b are free from the second bracket connection members 27b on the dispenser. In this manner, application of the sensor unit 5 in the sensor seat 38 causes disablement of all dispenser connection members 37a, 37b and causes the dispenser 2 to be released from the direct connections with the bracket 3.

Consequently, after application of the sensor unit 5 in the sensor seat 38, the dispenser 2 is only indirectly connected to the bracket 3 by means of being connected to the sensor unit 5 which is applied in the bracket 3.

Figs. 9a-9c show an alternative combination of a bracket 903 and a sensor unit 905 which may be used for hanging a dispenser as disclosed herein on a vertical wall. The bracket 903 as shown in Fig. 9a comprises a pair of first dispenser connection members 937a and a sensor unit connection member 937b. The first dispenser connection members 937a are in the form of broad hook elements which are arranged to cooperate with corresponding slots arranged in the rear wall of a dispenser (not shown). The sensor unit connection member 937b is in the form of a fastening hook which is arranged to form a snap- connection with a corresponding hole arranged in a rear wall of a sensor unit. The dispenser connection members 937a are disabled by removing them from the bracket 903. The hooks forming the first dispenser connection members 937a are releasable attached to the bracket 3 and can be easily removed without the use of tools.

After disablement, the first dispenser connection members 937a are replaced by adapters 906 which supplement the sensor seat 938, each adapter 906 being configured for accommodating an upper part of a load cell compartment 958 in the sensor unit 905, as shown in Fig. 9c. The adapters 906 also serve as dispenser connection members for forming a direct connection between a dispenser and the sensor unit 5 in the area of the load cell compartments in the sensor unit 5.
