This contains a housing, a cam follower which here has a triangular shape and extends from a hinged flap upwards. A spiral cam extends from the inside of the resealable closure cap. During opening of the closure cap, the cam follower slides along the spiral cam, causing the flap to move down.
  • CONFIRMATION COPY Another known from the prior art pouring device consists of a housing together with a removably arranged membrane with a loop or tab. In order to activate the pouring device, it is necessary to manually pull on the loop or tab until the membrane has been removed.
  • All of the pouring devices disclosed herein have several disadvantages in that they consist of either three parts, which makes them unnecessarily expensive and complicated, or that the hinged flap or its steering parts partially obstruct the pouring spout, resulting in uncontrolled pouring of the liquid, or each Manual removal of the membrane by means of a loop or tab forces it to often touch with a contaminated finger the area of the housing over which later the contents will flow.
  • the current three-piece pouring devices must be constructed relatively stable, since first the untwisting of the cap forces the movement of a cutting tool inside the housing, as far as the existing film layer is broken.
