Definitions

  • the invention relates to an adhesive tape dispenser.
  • Adhesive tape dispensers are well known from the prior art.
  • the EP 2 966 019 A2 discloses according to the preamble of claim 1 an adhesive tape dispenser for an adhesive tape roll with a core element, the dispenser consisting essentially of a carrier unit.
  • the document also discloses a metal bracket that presses a portion of adhesive tape onto an applicator roller.
  • a problem with the prior art is that tape can detach from the tape dispenser too early. It can happen that detached sections of adhesive tape are reconnected to the adhesive tape roll, which makes it more difficult to detach again. Sections of adhesive tape can also be knotted, with untying being impossible and/or very time-consuming in view of the adhesive effect of the adhesive tape. Another problem can be tearing of the adhesive tape if the forces acting on the adhesive tape become too great.
  • tape dispensers can be very noisy when applying tape. Since professional adhesive tape dispensers are often used for hours and several days a week, this high volume can be a burden for the employee and, in extreme cases, can also affect the health of the employee. It is therefore advantageous if the adhesive tape dispensers apply adhesive tape as quietly as possible.
  • the object of the present invention was therefore to overcome the disadvantages of the prior art and in particular to provide an adhesive tape dispenser with which adhesive tape can be applied particularly reliably, conveniently and with little noise.
  • the handle can preferably be designed as a tangential or radial handle.
  • the adhesive tape roll can optionally be part of the adhesive tape dispenser, but an adhesive tape dispenser without an adhesive tape roll is preferred, but which can hold an adhesive tape roll in the manner described above.
  • the friction bridge with the deflection bead improves the application of adhesive tape sections quite considerably. It is assumed - without being bound to a theory - that attractive interactions act between the deflection bead, in particular the transverse elevation or the deflection contact surface of the deflection bead, and in particular also the bridge sliding surface and the adhesive tape section lying on it, which increases the probability of an unintentional detachment of the adhering adhesive tape section to decrease. This can also involve, among other things, Van der Waals forces.
  • the bridge sliding surface preferably acts as a sliding or contact surface for the adhesive tape sliding along it. preferably its non-adhesive reverse side, but can also serve only or additionally as a contact surface.
  • the adhesive tape does not come into contact with the bridge sliding surface, or only partially, when passing the so-called bridge sliding surface.

  • the intermediate level is a level to be constructed hypothetically and not an actual device object of the adhesive tape dispenser device according to the invention.
  • This adhesive tape dispenser comprises a non-rotatable friction bridge with a bridge sliding surface and a deflection bead, the adhesive tape dispenser being designed and set up in particular in such a way that a section of adhesive tape of an adhesive tape roll present on the bearing, in particular rotatably mounted, slides over the deflection bead and, if necessary, also over the bridge sliding surface or can slide before hitting the application device.
  • the radial handle allows a particularly compact design if its longitudinal axis is arranged as described above.
  • the receiving device and the application roller are preferably located on the same side of the longitudinal axis.
  • the receiving device preferably also includes a mechanism for pivoting the bearing, in particular the central bearing, from the first bearing position into a second bearing position.
  • the bearing is preferably attached to a pivotable swivel arm.
  • the bearing is preferably rotatable and pivotable, in particular rotatable about its own bearing axis and pivotable by pivoting the pivot arm about a pivot arm axis, particularly preferably wherein the position of the bearing axis of deviates from the position of the swing arm axis and/or wherein said axes are substantially parallel.
  • the bearing, in particular the central bearing is preferably prestressed in order to move from the first to the second bearing position.
  • the first bearing position is preferably meant unless the context dictates otherwise.
  • the first storage position is preferably a position which is in the center of a cylindrical housing for the roll of adhesive tape.
  • a "handle" within the meaning of the present invention can take various forms. Tangential and radial grips have proven particularly useful.
  • the handle points with its longitudinal axis in the direction of the bearing, particularly in the first bearing position.
  • the longitudinal axis of a radial handle does not necessarily have to lead directly through the bearing in the first bearing position and/or the bearing axis in the first bearing position, but preferably close to it, in particular no more than 3 cm, particularly preferably no more than 2 cm, objected to by the bearing and/or the bearing axis in the first storage position, where the distance between the longitudinal axis and said bearing or said bearing axis in the first storage position is shortest.
  • the shortest distance between the longitudinal axis and the bearing is present in the first bearing position beyond the radial handle.
  • the grip does not point with its longitudinal axis to the bearing, particularly in the first and second bearing position.
  • the longitudinal axis of the handle is further away from the bearing and/or the bearing axis than with the radial handle, especially where the distance between the longitudinal axis and said bearing or said bearing axis is shortest, more than 3 cm, in particular more than 4 cm. particularly preferably more than 5 cm, in particular in the first and/or second storage position.
  • the shortest distance between the longitudinal axis and the bearing, in particular in the first bearing position is at a point on the longitudinal axis within the tangential grip.
  • the longitudinal axis of a radial grip preferably runs through an area in which the roll of adhesive tape is present when used in accordance with the generic type, this is usually not the case with a tangential grip.
  • the longitudinal axis of a tangential grip usually does not come close to the roll of adhesive tape when used in accordance with the generic type, and in particular has a minimum distance of 3 cm from the outside area the roll of tape.
  • the longitudinal axis of the handle can also be referred to as the handle axis.
  • Both tangential and radial grips can have a basic cylindrical shape, with the cross section usually not being round but elliptical.
  • tangential and radial grips are linear and not curved.
  • a "section of adhesive tape" within the meaning of the present invention can be connected to the roll of adhesive tape, but is preferably no longer attached radially to the core of the roll of adhesive tape, but is detached, but is preferably still connected at the end to the rest of the roll of adhesive tape.
  • This is therefore a section of adhesive tape that protrudes completely or partially from the roll of adhesive tape and is connected to the roll of adhesive tape at the end and/or in one piece, provided it has not yet been cut off.
  • the portion of tape includes an adhesive tape side and an opposite non-adhesive tape side. In most cases, this is achieved by the adhesive tape being coated with an adhesive layer on only one side.
  • “Rotationally fixed” in the sense of the present invention means that the corresponding element is fixed in a non-rotatable manner, for example connected or glued or screwed to it in one piece.
  • the adhesive tape dispenser can be turned as a whole by a user and thus also the non-rotating elements. What is meant is that a non-rotatable element does not rotate in relation to the main body of the rest of the adhesive tape dispenser, in particular not in relation to the handle or possibly the housing.
  • the reference system is therefore the adhesive tape dispenser itself, for example also the handle and possibly the housing of the adhesive tape dispenser.
  • a rotatable element is rotatably connected to the remainder of the adhesive tape dispenser, in contrast to a non-rotatable element.

  • the deflection bead includes a transverse elevation, in particular a transverse curvature. It has been shown that the noise when stripping off the roll of adhesive tape is reduced by the transverse elevation, in particular transverse curvature. Without being bound to a theory, it is assumed that the adhesive tape edges of the adhesive tape vibrate upon contact and that this vibration does not occur to the same extent if a transverse elevation, in particular transverse curvature, prevents said contact at the deflection bead.
