DETAILED DESCRIPTION

[0027] FIG. 1 shows a perspective view of the dispensing device 100 pursuant to the present invention for an adhesive tape roll, or for a medical product, such as a plaster, gauze bandage, bandaging material, etc., wound on a roll.

[0028] The dispensing device 100 has a base plate 101 equipped with a pin 102 for receiving the roll or the adhesive tape roll and a tearing section 103 having a tearing blade 104 at a distance from the pin 102. An adhesive tape roll, e.g. a roll of adhesive bandage, can be placed on the pin 102. In order to unwind the roll more easily, the pin 104 is formed rotationally symmetric along its longitudinal axis. The tearing blade 104 is equipped with teeth 105 to facilitate detaching of the adhesive tape or the medical product. The base plate 101 also comprises a fastening section 106 for partially gripping a rod 107. The fastening section 106 is formed as a clamping piece 108 for clamping the rod 107. It comprises a free arm 109 and an arm 110 connected to the base plate 101 and a crosspiece 111 connecting the free arm 109 to the arm 110. In the embodiment shown here, the crosspiece 111 is formed as an arc.

[0029] The dispenser 100 is characterized by providing at least one fastening unit 124 to join the connected arm 109, but in the present embodiment, in particular, by providing two of the fastening units 124 joining the free arm 109 to the connected arm 110 at the edges, and furthermore in that at least one fastening unit 124 joins the free arm 109 to the connected arm 110 in such a way as to form a receiving space 134 between the free arm 109, the crosspiece 111 and the connected arm 110 for receiving or for providing a passage for the rod 107 delimited by the at least one fastening unit 124.

[0030] The embodiment shown here contains an adapter 112 between the arm 110 and the free arm 109, the outer diameter of which is adapted to the inner diameter of the fastening section 106. The inner diameter of the adapter 112 can then be adapted to any diameter of the rod 107 being accommodated, preferably enhancing the clamping effect. The fastening section 106 features a seat 113 on the free arm 109 and on the arm 110 connected to the base plate 101, allowing for accommodation in each of a mounting unit 114 laterally attached to the adapter 112. This provides for a detachable connection between the adapter 112 and the fastening section 106. The seat 113 is formed as an indentation 115 and the mounting unit 114 as a bar 116 corresponding to the indentation 115. The bar 116 is adapted in such a way as to be inserted into the indentation 115.

[0031] The interaction between the indentation 115 and the bar 116 is further illustrated in FIG. 3. Preferably, the length of the adapter 112 is aligned with the width of the dispensing device 100. However, the length of the adapter may be less than 100 per cent of the width of the dispensing device 100 spanning the bar 107, and preferably amounts at most to between 70 and 90 per cent of the width of the dispensing device 100 and further preferably between 50 and 70 per cent of the width of the dispensing device 100, or preferably between 20 and 50 percent of the width of the device 100. Thus, the device 100 may be attached to rods 107, which have different diameters throughout their length.

[0032] The base plate 101 has an indentation 117 between the pin 102 and the tearing section 103. The base plate 101 is provided with an edge 118 on its end situated opposite the arm 110 comprising the semicircular indentation 117. This minimizes the contact surface between the hands and the (adhesive tape) roll with the dispensing device 100, thus reducing the risk of infection.

[0033] Furthermore, the pin 102 is equipped with a flange 119, which secures the roll to be wound on the dispensing device 100. In one alternate embodiment of the invention, the flange 119 is made of an elastic material, enabling the (adhesive tape) roll to be compressed over the elastic flange 119 when it is fed on to the dispenser until it has reached its desired position on the pin 102. Upon inserting the roll, the flange 119 is compressed and decompressed again, when the roll is fed on to the pin 102. This prevents the (adhesive tape) roll from sliding off the pin 102 and facilitates handling.

[0034] The tearing section 103 is formed as a second pin 120 with a second flange 121, made of the same material as the first pin 102, preferably of plastic. The tearing blade 104 is attached to the tearing section 103 or to the other pin 120 with fastening elements, for example with two screws as shown here. This detachable attachment of the tearing blade 104 to the tearing section 103 facilitates replacement of the tearing blade 104 if it has become worn or blunt due to frequent use.

[0035] The dispensing device 100 is attached to the rod 107, firstly by means of the fastening section 106 gripping around it and secondly by means of an aperture 122 in the form of a drilled hole in the free arm 109 and in the arm 110 connected to the base plate 101, respectively. The aperture 122 comprises a fastening unit 124 formed of, for example, a wing screw 123.

[0036] FIG. 3 depicts the cross-section III-III from FIG. 2 of the dispensing device 100 pursuant to the present invention. In particular, the fastening mechanism of the dispensing device 100 to the rod 107 is illustrated. A washer 125 is disposed between the fastening unit 124 and the free arm 109. Moreover, the wing screw 123 is fitted with a nut 133 at the end opposite the wings 126, thus allowing the free arm 109 and the arm 110 connected to the base plate 101 to be positioned between the wings 126 of the wing screw 123 and the nut 133. By turning the wing screw 123, the rod 107 can be fixed or clamped in the fastening section 106, or it can be released. The wing screw 123 can consequently be screwed to the reverse 131 of the base plate 101 with a (counter) nut 133. To prevent the nut 133 from turning when the wing screw 123 is turned, it should be mounted non-rotatably. The embodiment shown here thus provides undercuts 132 on the reverse 131 approximately aligned to the dimensions of the nut 133. These undercuts 132 are formed in such a way as to prevent rotation or co-rotation of the nut 133. In order to clamp the rod 107, it is therefore sufficient to turn the wing screw 123, due to the self-locking position of the nut 133. This is advantageous particularly when the reverse 131 of the base plate 101 is not accessible for countering the nut 133 (manually).

[0037] Moreover, FIG. 3 depicts the mounting of the cylindrical second pin 120 or the tearing section 103 to the base plate 101. The tearing section 103 as well as the pin 102 not shown in FIG. 3 have an end-to end tunnel 128, in which a screw 129 or similar is accommodated. The base plate 101 has drill holes 130, allowing the tearing section 103 and the pin 102 to be mounted to the base plate 101 by means of the screw 130 and a nut 127. This also allows for the replacement of the pin 102 and/or the tearing section 103 in the event of damage or heavy usage. Again, the reverse 131 of the base plate 101 has undercuts 132, allowing insertion of the nuts 127 to counter the rotation of the screw 129.

[0038] Mounting the dispensing device 100 to the rod 107 by means of the fastening section 106 and the fastening units 124 allows for single-handed operation of the dispensing device 100. Contamination of the dispensing device 100, the roll or the adhesive roll is thus prevented as the hands only come into contact with the part of the adhesive tape roll or medical product that is wound on the roll which is torn off.

[0039] The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are to be included within the scope of the following claims.
