The invention relates to a closure device for a vacuum sample collector, comprising an external cap ( 2 ), in a hard material, preferably a hard plastic component, with a top face ( 4 ) and a side skirt ( 5 ) surrounding the above, which may be connected to a sleeve-like opening section of the vacuum sample collector, and a sealing element ( 3 ) arranged on the container side of the external cap ( 2 ) made from an elastic material, preferably a soft synthetic component. The external cap ( 2 ) is turned inwards on its top face ( 4 ), and the section of the cap turned inwards forms a depression, the floor of which ( 10 ) has a turned-up section which faces outwards and which forms an essentially cylindrical projection ( 11 ), with a flat opening ( 12 ) and which, within the depression, terminates in an opening ( 13 ), arranged in a recessed manner with relation to the front face of the external cap ( 2 ), such that said opening is outside the contact area of a finger. The sealing, element ( 3 ) fills the opening ( 12 ) and, furthermore, lines the inner wall of the inverted section ( 8 ) and a groove ( 19 ), which is formed on the inner side of a front face of the external cap ( 2 ) between the side skirt ( 5 ) and the inverted section ( 8 ), whereby a gap ( 22 ) remains on the inner wall ( 21 ) of the side skirt ( 5 ) to accept the sleeve-like opening section of the vacuum sample collector in a sealed manner. The invention further relates to a vacuum sample collector. |
