In the holding position, the bottle 32 is secured against removal from the container receptacle 62.
  • the carrier element 114 can be acted upon by a biasing force of the coil springs 130 opposing force. For this reason, the carrier element forms an actuating element 140 in order to transfer the holding part 106 from the holding position into a release position. If the carrier element is acted upon by the force, this leads to the displacement of the holding part 106 along the displacement direction 120 against the force of the coil springs 130. The holding part 106 can be displaced until the carrier element 114 strikes against the web 100. In this case, the web 102 just engages in the space between the holding arms 116, 118 and thereby forms an edge of the through-opening 122 (FIG. FIG. 5 ).
  • the passage opening 122 is aligned with the insertion opening 78. This makes it possible to remove the bottle 32 in the release position of the holding part 106 from the container receptacle 62 by the neck portion 40 and the cover 54 away from the jet pipe 12th be pulled out of the container receptacle 62.
  • the admixing device 10 can be raised.
  • the passage opening 122 is just dimensioned so that the cover 54 can be passed through the passage opening 122 with little play.
  • the sealing element 84 can act as a biasing element by the sealing element 84 deformed again and to a certain extent "de-dusted". This allows the lid 54 on the heel 94 with a release force to act against the insertion 80. This facilitates the detachment of the admixing device 10 from the bottle 32.
  • the user can first transfer the holding part 106 under the application of force from the holding position into the release position. Then, as explained above, the user can insert the bottle 32 with the neck portion 40 and, if present, the lid 54 into the container receptacle 62. Under the action of the restoring device 128, the holding part 106 is transferred from the release position into the holding position, without the need for any action by the user.
  • the guide members 142 include a bevel oriented relative to the insertion direction 80. This makes it possible to transfer the holding part 106 to a certain extent "automatically" from the holding position to the release position when the bottle 32 is inserted into the container receptacle 62. In this case, the neck portion 40 or, if present, the cover 54, the guide members 142 contact. Due to the slope, this leads to a force component along the displacement direction 120 on the holding part 106. This force component is directed so that the holding position engaging holding part 106 is moved to the release position, after which the bottle 32 can be further inserted into the container receptacle 62. Under the action of the restoring device 128, an automatic displacement of the holding part 106 from the release position back into the holding position also takes place in this case.
  • the admixing device 10 proves to be versatile. It allows the picking and holding of bottles 32, which are equipped with or without cover 54.
  • FIG. 6 shows in one of the FIG. 3 corresponding manner, such a bottle 32 without the lid 54.
  • the neck portion 40 is engaged by the support member 48 of the support arms 116, 118 and held in the container receptacle 62.
  • the edge of the opening 50 can contact the sealing element 84 projecting into the receiving space 76 at its sealing surface 86.
  • This allows a liquid and gas-tight mounting of the bottle 32 to the admixing device 10.
  • the sealing surface 86 is positionally variable. Depending on the presence of the cover 54, the sealing surface 86 can assume different positions and ensure a seal in the presence or in the absence of the cover 54.
