Definitions

  • the invention relates to a closure with a screw cap and an externally threaded container neck or a lower part of the closure that can be connected to the container neck with an externally threaded pouring spout, in which the screw cap from the cap base and cap jacket has an internal thread on the inside of the cap jacket and on the external thread of the container neck or the pouring spout of the bottom part of the closure can be screwed on and off, in which the container neck in the transition area to the container or the pouring neck in the transition region to the bottom part of the closure carries an arc-shaped locking cam, which is formed directly on the container neck or the pouring neck of the bottom part, for example ends flush with an edge formed on the end face of the cap shell of the screwed-on screw cap and has a flat rising flank in the screwing-on direction and a steep slope in the unscrewing direction Flank forms, in which the locking cam in connection with a locking element of the screw cap, the screw cap in the unscrewing direction until the locking connection is triggered on the container
  • Such a closure is shown in US Pat. No. 4,331,247 as known.
  • a latching element in the form of a latching tab is molded into the front edge region of the cap jacket so as to protrude downward.
  • the edge area is flush with the outside of the cap jacket.
  • a locking cam is arranged opposite the locking tab.
  • the detent flap is connected on the one hand at its root and on the other hand to its stop surface, which cooperates with the stop flank of the detent cam, on the front edge of the cap jacket.
  • the locking element of the screw cap is designed as a snap-in receptacle in the end face of the cap shell.
  • the cap jacket has a thin-walled point, so that the snap-in receptacle can be deflected radially inward and brought out of the rotating area with the snap-in cam.
  • the axial latching has the disadvantage that the cap jacket in the area of the latching receptacle is subjected to a very high axial load when it runs onto the latching cams, which often leads to damage or even destruction of the screw cap, particularly in the area of the thin-walled point.
  • the end face of the cap jacket has an edge which projects radially outward all the way around the cap jacket, and that the latching element is formed only on one side on the end face provided with the edge and to it
  • the stop surface protrudes freely and that the locking tab is flush with the inner and outer contour of the edge.
  • the stop surface of the latching tab is also wide in the radial direction, as a result of which the secure support on the stop flank of the latching cam is stabilized and lateral evasion is prevented.
  • the operation of the child lock is simple, since the locking element, which is only connected to its root, can easily be deflected upwards in the axial direction to remove the lock.
  • the molding of the locking cam on the container neck or on the pouring neck 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 nozzle or the pouring nozzle of the lower closure part passes over a shoulder into the container or into the lower closure part, and that the latching cam is integrally formed on the shoulder.
  • Childproofing 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 an indented 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 slides over the locking teeth of the container neck or pouring spout, but in the unscrewing direction of the screw cap is held non-rotatably on the container neck or pouring neck until the tear-off webs break off.
  • a screw cap 10 is placed on one Screwed 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 formed directly on the container neck 21.
  • the circular-arc-shaped locking cam 24 has a flat rising flank 25 and ends in a steep stop flank 26, which becomes effective in the unscrewing direction of the screw cap 10. As shown in FIG. 2, 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 such that it slides in the screwing-on 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 through 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 shell 12.
  • the locking tab 16 forms on its end face a stop surface 18 which is oriented approximately vertically and in the unscrewing direction Screw cap 10 strikes the likewise approximately vertically aligned stop flank 26 of the locking cam 24. The screw cap 10 is therefore secured against unscrewing.
  • the locking tab 16 is raised so far that the stop surface 18 of the locking tab 16 is moved out of the area of the stop flank 26 of the locking cam 24. Then the locking tab 16 can also pass through the locking cam 24 in the unscrewing direction of the screw cap 10.
  • the locking tab 16 carries a molded, outwardly projecting handle 17 to facilitate grasping and lifting the locking tab 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 turned in the screwing 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 depressed starting point and in an extended pouring position.
  • the child safety device 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 of the lower closure part.
