<p>The invention includes a method for closing a hole, such as a mounting hole, which is constructed with a circular opening (5,7,9) located in a surface (2,3,4), and in which the bottom of the hole contains a mounting member such as a screw, pointed screw or a threaded bolt (11) and the surface (2,3,4) forms part of a system that is located in an environment that places special requirements on hygiene where a hole is closed with an elastic ball (6,8,10) that is pressed into the hole through the circular opening (5,7,9), where the hole is internally formed as part of a sphere having a diameter (16) which is larger than the hole's circular opening diameter (15) and which is equal to or less than the diameter of the ball (19). This ensure that holes are effectively closed, thus preventing impurities and / or bacteria from entering into the holes. The invention also includes the use of the above described method for closing holes in systems and applications that place special demands on hygiene and clean design as specified by the so-called 3A and EHEDG standards.</p> |
