Patent attributes
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.
