Definitions

  • the latching element of the screw cap is formed as a detent flap formed on the end face of the cap jacket at an acute angle in the circumferential direction of the cap jacket so that it slides in the screwing-on direction with deflection over the rising flank, but in the unscrewing direction with a the front stop surface is held on the stop flank of the locking cam, and that an outwardly projecting handle is formed on the locking tab for lifting the same and thus for triggering the locking connection.
  • the latching tab of the screw cap When the screw cap is screwed on, the latching tab of the screw cap can be easily deflected when passing through the latching cam without being overstressed.
  • the end stop of the latching tab lies against the stop flank of the latching cam and thus secures the screw-on end position.
  • the locking tab With the handle, the locking tab can be lifted slightly and brought out of operative connection with the locking cam. The lifting movement is limited by the stop of the locking tab on the cap jacket, which also prevents overloading of the locking tab in this regard.
  • the molding of the locking cam on the container neck or on the pouring spout of a lower closure part is facilitated in that the latching cam is formed directly on the container neck or the pouring neck of the lower closure part and is approximately flush with an edge formed on the end face of the cap shell of the screwed-on screw cap. It is advantageous if it is provided that the container neck or the pouring neck of the lower closure part passes over a shoulder into the container or into the lower closure part, and that the latching cam is formed on the shoulder.
  • the locking tab is approximately flush with the inner and outer contour of the edge of the cap shell and that the handle is flush with the outer contour of the locking tab, and that the locking tab how the edge of the cap jacket is designed in a circular arc.
  • the type of closure can vary.
  • the childproof lock can also be implemented with a closure, which is characterized in that the lower closure part has a U-shaped base part which can be connected to the container neck of the container, that a bellows connects to the base part, which is integrally connected to the pouring nozzle, so that the pouring spout can be brought from a pressed-in starting position into an extended pouring position and vice versa, or that a guarantee ring is formed on the cap jacket via tear-off webs, which is provided with locking teeth and cooperates with counter-locking teeth of the container nozzle or the pouring nozzle so that the guarantee ring in the unscrewing direction of the screw cap over the Locking teeth of the container neck or pouring spout slide, but is non-rotatably held on the container neck or pouring spout in the unscrewing direction of the screw cap until the tear-off webs break off.
  • a screw cap 10 is screwed onto a container neck 21 of a container 20.
  • the screw cap 10 consists of a cap base 10 and a cap jacket 12.
  • the cap jacket 12 has an internal thread 13 so that it can be screwed onto the container neck 21 with a corresponding external thread 22.
  • the cap jacket 12 merges in the region of its end face 15 into an edge 14 which protrudes all around the cap jacket 12.
  • the container neck 21 merges into the container 20 via a shoulder 23.
  • a locking cam 24 is formed on the shoulder 23, which is located in the root region of the container neck 21.
  • This locking cam 24 is located under the edge 14 and the cap jacket 12 is, however, also integrally formed on the container neck 21.
  • the circular-arc-shaped locking cam 24 has a flat rising edge 25 and ends in a steep stop flank 26, which becomes effective in the unscrewing direction of the screw cap 10.
  • the outer contour of the locking cam 24 can be approximately flush with the outer contour of the edge 14 of the screwed-on screw cap 10.
  • a locking tab 16 is formed at an acute angle.
  • the locking tab 16 is arcuate and aligned so that it slides in the unscrewing direction of the screw cap 10 over the rising flank 25 of the locking cam 24 and is deflected so far upwards that the locking tab 16 can pass the locking cam 24.
  • the locking tab 16 can be approximately flush with the inner and outer contour of the edge 14 of the cap jacket 12.
  • the latching tab 16 forms a stop face 18 on its end face, which is oriented approximately vertically and abuts the stop flank 26 of the latching cam 24, which is also approximately vertically aligned in the unscrewing direction of the screw cap 10. The screw cap 10 is therefore secured against unscrewing.
  • the detent flap 16 carries an integrally formed, outwardly projecting handle 17 in order to facilitate grasping and lifting of the detent flap 16.
  • the child lock according to the invention can not only be implemented with a simple screw cap according to the exemplary embodiment.
  • the screw cap can also wear a guarantee ring in a known manner, which is connected to the cap jacket by means of tear-off webs. Tear-off webs are then arranged at the sides of the locking tab 16.
  • the guarantee ring is connected to the container neck via separate snap-in connections so that it is rotated in the screwing-on direction, but is held in the unscrewing direction.
  • a lower closure part with pouring spout can also be provided.
  • the lower closure part is connected to the container opening of the container.
  • the pouring spout can be integrally connected to a U-shaped base part via a bellows.
  • the base part is used for fastening to the container and the bellows allows the pouring spout to be set in a pressed-in starting point and in an extended pouring position.
  • the childproof lock according to the invention can be implemented on any closure which has a screw cap with a cap jacket which can cooperate with a locking cam of the container neck or the lower closure part.
