<p>A valve cap (18) serving for securing against unintentional loosening of a double valve (1) mounted on a container (3) serving of storing a liquid. The upper part of the double valve is formed as a basket having a cylinder mantle (9) with a free top edge (10) flushing with the top edge (11) of the connection piece. Along this is formed an outwardly directed bead (14). The valve cap (18) consists of an annular skirt (19) which, at mounting of the valve cap, is pressed in under the bead (14), and an inwardly directed collar (20) which, during this, is made to abut against the top edge (11) of the connection piece (14) and/or the top edge (10) of the cylinder mantle. Thereby, disadvantages are avoided of a coupling (4) belonging to the valve screwing the valve (1) loose of the connection piece (2) so that the pressure gas blows out on the operator or that he is hit by the unscrewed valve (1). The container (3) cannot be used unnoticed for hiding e.g. drugs either.</p> |
