A hollow cylindrical container (40) on the inside of the middle part (61) has a hole on its centre bottom end, and a filter (402) on its front end. Outside the filter is an insulating piece (401). The ball-point pen-shaped main part has a top (60), middle and bottom part. A vacuum tube (621) on the inside of the bottom part fits into the rubber's hole which has a soft support (612) on its upper side. The middle part has a curved lid (611).
