Abstract: A support bar for a material web wound onto a roll. The support bar has, on each end, a bearing journal which is arranged on the longitudinal axis thereof. At least one of the two bearing journals is provided with a fitting surface which is not designed as a rotational surface and is rotatably arranged on the support bar. The bearing journal can be inserted into a guide of a dispenser. The guide is continuous from the insertion position to the dispensing position.

Abstract: A dispensing system has a dispenser for sections of a material web wound onto a roll. A support bar is provided, on each end, a bearing journal protruding out from the roll. At least one of the two bearing journals has a mating surface which is not designed as a rotational surface. The dispenser has a guide for each bearing journal that extends to a dispensing position. A counter surface for the mating surface is provided at the beginning of the guide for each bearing journal that has the mating surface. The insertion of the roller into the dispenser is only possible if the mating surface coincides with the counter surface, which extends to in the dispensing position. The roller is rotatably arranged about the central area of the supporting rod, which does not rotate in the dispensing position.

Abstract: The invention relates to hand disinfectants, containing at least 40 weight percent of water and at least one dissolving ether, wherein the at least one dissolving ether is an ether that has a molecular weight greater than 107 daltons, a melting point less than 303 K, and a boiling point greater than 373 K, the solubility in water of the ether being at least 50%, wherein the ether reduces the solubility of calcium adducts and magnesium adducts of proteins and of amino sugars in water at least to a half, preferably to a third, especially preferably to a fourth, in particular to a fifth. Said hand disinfectants can be used as monoalcohol-free hand disinfectants.

Abstract: A support bar has a central region for a material web wound to a coreless roll and a first and a rotatable second bearing journal each projecting beyond the roll. The support bar includes a first and a second part. The first part extends throughout the roll. A first end of the first part forms the first bearing journal. A second part, formed as a rotary body that is rotatable relative to the first part has a second end that forms the second bearing journal. A second end of the first part is formed with an axial bore and a first end of the second part is latched in the axial bore within the roll.

Abstract: A foaming soap dispenser includes a housing having a discharge opening at the bottom, a receptacle in which a liquid soap reservoir can be replaceably inserted and a soap container beneath the reservoir. A peristaltic or squeezed-tube pump for the soap and a diaphragm pump for feeding foaming air to a foaming device disposed close to the discharge opening, can be driven separately electrically.

Abstract: A container has an opening lying in a plane, wherein the opening is provided on a connecting piece of the container. A closure of the container can be removed by displacement in the plane. At least one guide element is provided on the connecting piece, on or in which the closure can be displaced relative to the container. The closure has at least one recess on at least one of its outer surfaces.

Abstract: A container includes a connection with an opening and a removable closure. At least one guide element, on or in which the closure is displaceable, is provided on the connection. At least one socket projecting forwardly in a sliding direction is formed on a side of the container having the connection. A dispensing system having the container is also provided.

Abstract: A method and a dispenser dispense a sheet of paper through a bottom outlet gap from a stock. A sensor activates, upon detection of a person, an electric drive which delivers a portion of paper from the outlet gap so that the sheet of paper can be torn off by hand. When the delivered sheet of paper is torn off, a switch is actuated. Actuation of the switch puts the dispenser in an operational readiness for delivery of another portion of paper.

Abstract: A paper dispenser dispenses paper sheet by sheet. Paper projects from a dispenser housing in an operational position so that it can be pulled off from a supply roll by hand. The paper dispenser has a delivery roller driven by the web of paper that is being pulled. A stop which is moved from a rest position to a blocked position against the force of a return spring blocks the rotation of the delivery roller so that the sheet is torn off due to the pulling power, and is slowed down by a braking device when returning to the rest position. A post-delivery device is configured to further drive the delivery roller once the sheet has been torn off and completes the rotation in a time-delayed manner so that the paper projects from the dispenser housing and can be pulled again.

Abstract: A paper dispenser has a dispensing opening for paper and also a first roll, which is located in a dispensing position, and a guide path, which leads into the dispensing position and contains a storage position for a reserve roll. The dispensing opening is of a size which, once the first roll has been used up, allows manual access to the paper of the reserve roll, while the reserve roll is still in the storage position.

Abstract: A paper dispenser dispenses paper from a dispenser roll lying in a dispensing position. The paper dispenser contains two transport rollers for the web of paper, the rollers defining a gap, and a mobile sensor element for identifying the end of the web of paper. The sensor element being arranged between the two transport rollers downstream of the gap in the direction of transport of the paper.
