Claim:
1. A cap, comprising: a front wall delimited by a circumferential edge and being gas-permeable; and a jacket wall attached to said circumferential edge of said front wall, at least part of the cap having a first thickness that is less than a second thickness of said jacket wall in a section of said jacket wall in an area or end of said jacket wall facing away from said front wall; said jacket wall in an area near said front wall, having a first thickening section following from the circumferential edge, in which a thickness of said jacket wall exceeds a thickness of said front wall; said jacket wall having an intermediate section following from said first thickening section, said first thickness of said jacket wall in said intermediate section being less than said thickness of said jacket wall in said first thickening section; said jacket wall having a second thickening section, following from said intermediate section and extending until an end of said jacket wall that is farthest from said front wall; and said second thickness of said jacket wall being greater in said second thickening section than said first thickness of said jacket wall in said intermediate section; said jacket wall having a thickness being a continuous course free of kinks or edges in an axial or radial direction; and/or a respective average thickness in respective one of said first thickening section, said second thickening section and said intermediate section of said jacket wall being deemed to be said thickness; and/or said jacket wall, with an exception of an area of said locking protrusions or said recesses, being rotationally symmetric; said thickness of said first thickening section, said first thickness of said intermediate section, and said second thickness of said second thickening section having the following ratio: 2<d1:d2<5 and/or 2<d3:d2<5 and/or 0.8<d1:d3<1.25; d1 being said thickness of said first thickening section, d2 being said first thickness of said intermediate section, and d3 being said second thickness of said second thickening section; and/or said thickness of said first thickening section, said first thickness of said intermediate section, and said second thickness of said second thickening section being set as follows: 150 μm<d1 <250 μm and/or 50 μm<d2<100 μm and/or 150 μm<d3<250 μm; a height h1 of said first thickening section, a height h2 of said intermediate section, and a height h3 of said second thickening section having the following ratio: 0.2<h1:h2<0.6 and/or 0.8<h3:h2<1.25 and/or 0.2<h1:h3<0.6; and/or said jacket wall having a height of 2-80 mm; and/or a ratio between said height and a maximum dimension, being a diameter or diagonal, of said front wall is between 0.01 and 55; said front wall being circular and having a diameter of 1-50 mm; or said front wall being square or rectangular, and side edges of said front wall having a length between 2 and 40 mm; said cap having at least one of locking recesses formed therein or locking protrusions on said end of said jacket wall facing away from said front wall for removable attachment to a measuring device; or at least one of said locking recesses or said locking protrusions each having at least one of a same normal distance from said front wall, are distributed evenly in a circumferential direction of said jacket wall, or whereby a total number of said locking recesses and/or said locking protrusions being two or four; and/or at least one of said locking recesses or said locking protrusions protruding away from said jacket wall at an angle of 5°-40° and/or no more than 2 mm.
