A sheet product dispenser is provided including a housing including a roll holder configured to receive a product roll, a dispensing mechanism configured to dispense a portion of the sheet product from the product roll, a sensor configured to emit a signal toward the product roll and receive a reflection of the signal from a surface of the product roll, and a controller. The controller is configured to receive an indication of replacement of the product roll, determine a time-of-flight of the signal, and determine an expected time-of-flight (or corresponding distance of travel) of a theoretical signal to a theoretical full product roll. The controller is further configured to compare the time-of-flight (or a corresponding distance of travel) of the signal to the product roll to the expected time-of-flight or distance, and adjust a product depletion curve based on the comparison.

A roll towel dispenser includes a frame configured to support a first roll of first paper towel and a second roll of second paper towel and a main roller coupled to the frame. During operation, the first paper towel and the second paper towel are positioned adjacent the main roller such that the first paper towel is positioned between the second paper towel and the main roller. The main roller is configured to engage the first paper towel such that rotation of the main roller moves the first paper towel from the first roll, at least partially around the main roller, and through an outlet of the roll towel dispenser. The first paper towel slips relative to the second paper towel while the main roller moves the first paper towel such that only the first paper towel is dispensed through the outlet.

A method of reducing sheet product waste generated during use of a sheet product dispenser in a particular location and over a broad range of usage rates includes designing a dispenser. The design includes determining a desired housing size to obtain a top to bottom height for sheet product roll storage within the housing, dividing the height by two to obtain a maximum roll diameter, locating two roll holders in the housing so that each holder may accept a roll having the maximum roll diameter, positioning a first roll of the maximum roll diameter in a first one of the two roll holders, and positioning a second roll of the maximum roll diameter in a second one of the two roll holders so that two rolls of equivalent length are configured to be dispensed sequentially from the dispenser. The installation and use of two rolls of maximum roll diameter reduces waste. Dispensers formed according to this method are also described.

Devices, systems, and methods of the present disclosure are directed to dispensing wipes that are treated as the wipes move through a housing of a dispenser. Such in situ treatment of the wipes may facilitate, for example, achieving control over one or more of the concentration, composition, or distribution of one or more chemicals carried by the wipes. Further, or instead, the one or more chemicals may be formed within the housing (e.g., just prior to treating the wipes), which may be useful for treating the wipes with chemicals that have limited stability and/or for reducing chemical handling requirements along a supply chain.

A sheet product dispenser includes a transfer bar, a roller assembly, a motor, a sensor, and a controller. The transfer bar is movable between first and second positions. The roller assembly, disposed proximate the transfer bar second position, has a drive roller and a pinch roller that define a nip. The motor is in operable communication with the transfer bar to move the transfer bar between the first and second positions. The sensor is in operable communication with the dispenser cover. The controller is in operable communication with the sensor and the motor, and is responsive to executable instructions to facilitate actuation of the motor in response to a signal from the sensor to cause the transfer bar to move between the first position and second positions. The transfer bar includes at least one finger that drives an end of a roll of sheet product towards the nip upon actuation of the transfer bar from the first position to the second position.

An example sheet product dispenser includes a housing, a first roll holder, and a second roll holder. A first roll of sheet product is positioned on the first roll holder and assigned as a primary roll and a second roll of sheet product is positioned on the second roll holder and assigned as a secondary roll. A dispensing mechanism is configured to dispense sheet product from at least one of the first roll and the second roll. A sensor is configured to sense measurement data associated with the primary roll, including sensing when the primary roll rotates to dispense and measuring the diameter of the primary roll. A data communication device is in communication with the sensor and configured to transmit the measurement data. A controller is configured to determine situational information regarding the sheet product dispenser and provide corresponding alerts to users regarding the situational information and measured data.

A sheet material dispenser can include a sheet material transfer assembly operable to automatically transfer feeding or dispensing of sheet material between a plurality of supplies of sheet material. The sheet material transfer assembly can include a frame that is movable between a plurality of positions including a first position that facilitates feeding of the sheet material from a first supply of sheet material, and a second position that facilitates feeding or dispensing of sheet material from a second supply of sheet material. The frame of the sheet material transfer system can shift or move to the second position for dispensing sheet material from the second supply of sheet material when the first supply of sheet material is fully dispensed.

Various tissue dispensers are disclosed. The tissue dispenser can hold a main roll of tissue and a stub roll of tissue. In response to the tissue of the stub roll being exhausted, an advance system of the tissue dispenser can automatically transition the tissue dispenser to dispensing tissue material of the main roll.

A web material dispenser includes a housing and a pivotable roll support assembly provided therein. A first mandrel is provided at a first attachment location of the roll support assembly to support a first roll of web material. A second mandrel is provided at a second location of the roll support assembly to support a second roll of web material. The web material dispenser permits one-handed operation to replace the rolls of web material and to change positions of the mandrels within the dispenser. The roll support assembly may have a linkage arm and/or a roll support arm. Positions of the first and second mandrels relative to the dispenser's opening can be switched by pivoting the linkage arm relative to the housing and by pivoting the roll support arm relative to the linkage arm. A method for switching positions of rolls in the web material dispenser is also provided.

A bushing for a web material roll including a body sized to be fitted into the web material roll; the bushing further including a wall extending across the central cavity of the web material roll when the bushing is in the central cavity of the web material roll and defining an opening for receiving a roll support therethrough, the opening being bordered by a roll support contacting surface, the bushing having one or more bearing surfaces for contacting the roll support and supporting the web material roll, the one or more bearing surfaces including at least the roll support contacting surface bordering the opening. A web material roll, a web material roll retention assembly and a method for placing a web material roll in a web material roll dispenser are also provided.
