  • Patent number: 9522769
    Abstract: Push-pull closure for a drink container comprising a body element which comprises a through-opening and a fastening device, with which it may be sealingly and releasably connected to an opening of the drink container, a mouthpiece which may be axially displaceably inserted into the through-opening of the body element and which comprises at least one locking portion which may engage behind the through-opening of the body element, and a locking element which may be releasably attached to the inner face of the body element facing the drink container, the locking element being arranged so that the locking portion of the mouthpiece may not adopt a position in which it does not engage behind the through-opening of the body element, when the mouthpiece is inserted into the through-opening and the locking element is attached to the inner face of the body element.

  • Patent number: 8708174
    Abstract: A bottle teat comprising: A nipple sleeve having a hollow nipple and a through-hole connected at the bottom to a hollow nipple sleeve which is connected at the bottom to a nipple flange that is connected to the nipple sleeve to be fastened to a bottle by a fastening ring which serves at the bottom with an annular disc-shaped ring flange overlapping the nipple flange, A contact area projecting downward or upward from the nipple flange, or from the nipple sleeve above the nipple flange outward into the area for placing a ring flange, and A lip valve that is opened when the nipple flange is not fastened to a bottle arranged in a deforming area next to the contact area so that the deformation of the nipple flange that arises from pressing the fastening ring against the contact area closes the valve.
