Abstract

A rotary shaver ( 1 ) comprising a metal external cutting element ( 7 ) and a disc-shaped element ( 10 ) having a central axis ( 12 ). The disc-shaped element covers at least part of the external cutting element. The disc-shaped element is in contact with the external cutting element by means of a raised ring-shaped rim ( 15 ) extending between a side surface of the external cutting element and a side surface of the disc-shaped element, which raised ring-shaped rim has a height of at least 0.1 millimetre in a direction parallel to the central axis and a width of less than 0.35 millimetre in a direction radial to the central axis.

First claim

1 . A rotary shaver comprising a metal external cutting element, an internal cutting element being rotatable with respect to the external cutting element about an axis of rotation, and a disc-shaped element having a central axis extending coaxially with the axis of rotation, which disc-shaped element covers at least part of the external cutting element, characterized in that the disc-shaped element is in contact with the external cutting element by means of a raised ring-shaped rim extending between a side surface of the external cutting element facing the disc-shaped element and a side surface of the disc-shaped element facing the external cutting element, which raised ring-shaped rim has a height (H) of at least 0.1 millimetre in a direction parallel to the central axis and a width (W) of less than 0.35 millimetre in a direction radial to the central axis.

2 . A rotary shaver according to claim 1 , wherein the ring-shaped rim is a continuous uninterrupted rim.

3 . A rotary shaver according to claim 1 , wherein the ring-shaped rim forms part of the disc-shaped element.

4 . A rotary shaver according to claim 3 , wherein the disc-shaped element comprises a disc-shaped covering member, and wherein the ring-shaped rim extends along a circumference of the disc-shaped covering member on a side surface of the disc-shaped covering member facing the external cutting element.

5 . A rotary shaver according to claim 1 , wherein the ring-shaped rim forms part of the external cutting element.

6 . A rotary shaver according to claim 1 , wherein the ring-shaped rim encloses a gap which is present between the external cutting element and the disc-shaped element and which has a gap height equal to or greater than the height (H) of the ring-shaped rim.

7 . A rotary shaver according to claim 1 , wherein the disc-shaped element is made of plastic.

8 . A rotary shaver according to claim 1 , wherein the disc-shaped element and the external cutting element are connected to each other by means of a glue provided on the ring-shaped rim.

9 . A rotary shaver according to claim 1 , wherein the external cutting element is provided with a passage, whilst the disc-shaped element is provided with a pen having a length, wherein the pen is press-fitted in the passage, and wherein between a wall of the passage and the pen at least one vent extends at least along the length of the pen.
