  • the device so the housing 2, the actuating element 16 and / or the blocking element 24 is formed of polycarbonate. It is also advantageous if the valve element is made of a rubber, such as LSR, liquid silicone rubber.
  • FIG. 5 shows a top view of the device 1 according to the invention. It can be seen the two opposing locking elements 121, which are arranged and guided in receptacles 122 of the collar 120. If a first storage vessel is inserted into the collar 120, the locking elements 121 migrate laterally and allow the head of the storage vessel to pass. Subsequently, the locking elements are moved back inward due to the bias of the spring arms and thereby hold the first storage vessel.
  • two such locking elements are provided. Alternatively, only one such locking element can be provided or it can also be provided several locking elements, such as three, four or more.
  • FIG. 6 shows in an enlarged section the arrangement of the locking element 121 in the receptacle 122, as held by the spring arm, which engages from below into a groove of the locking element 121. If the locking element displaced, so the spring arm 123 bends correspondingly elastic and returns after the shift load back.
  • FIG. 7 shows the valve element 6 with membrane 91 which is pierced by the mandrel 82. For this purpose, the mandrel 82 is beveled above.
