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 lower closure part can be unscrewed and unscrewed, and in which the cap jacket is connected via a latching connection to a latching cam of the container neck or the lower closure part, which can be triggered by pressing in part of the cap jacket.
  • This known closure can only be opened by twisting the screw cap and is therefore not childproof.
  • Child-resistant screw caps consist of an inner and an outer cap.
  • the inner cap is connected to the outer cap with a snap-in coupling, which acts only in the screw-on direction but not in the unscrewing direction, so that the closure cannot be opened with a simple rotary movement of the outer cap.
  • a snap-in coupling acting in the unscrewing direction is produced, so that the screw cap can then be unscrewed.
  • This requires a double operation, so that the closure is childproof, as shown in DE-GM 78 12 241, DE-GM 76 34 267 and DE-OS 24 43 803.
  • a one-piece childproof screw cap of the type mentioned is known, in which a snap-in receptacle is formed in the end face of the cap jacket.
  • the end face runs onto a locking cam which is attached to the container neck or the sealing jacket in an extension of the cap jacket.
  • the locking cam is locked in the locking receptacle and fixes the screw cap in the unscrewing direction.
  • the snap-in connection is released and the screw cap can be unscrewed.
  • this requires a double operating receptacle on the screw cap.
  • the locking is in the axial direction, while the unlocking takes place in the radial direction.
  • the axial latching has the disadvantage that the cap jacket is subjected to a very high axial load in the area of the latching receptacle when it runs onto the latching cams and continues to turn the screw cap. This often results in damage or destruction of the screw cap in this area.
  • This object is achieved according to the invention in that, outside of the area covered by the cap jacket, the container neck or the lower closure part, following the external thread, bears a locking cam which protrudes from the screw cap and which cooperates with a molded locking tab which projects outwards in the end area of the cap jacket, whereby the latching tab protrudes against the screw-on direction of the screw cap on the cap jacket, can be deflected inwards by the latching cam in the screwing-on direction of the screw cap and can be fixed in the unscrewing direction of the screw cap with its counter-stop face formed on the end face to a stop surface of the latching cam, and that the latching connection can be fixed by radially pressing in the latching tab can be triggered between locking cams and locking tabs and the screw cap can be released for unscrewing.
  • the locking and unlocking takes place in the radial direction, so that when the screw cap is tightened there is no overload in the area of the locking connection.
  • the locking tab is easy to divide and form on the cap jacket of the screw cap, without making the screw cap significantly more difficult to manufacture. It is also easy to initiate the snap-in connection, since only the snap-in tab protruding from the cap jacket has to be pressed inwards.
  • an embodiment is advantageous, which is characterized in that the locking tab is directed approximately tangentially protrudes from the cap jacket.
  • the locking tab extends at least partially over the height of the locking cam in the closed end position of the screw cap and projects beyond the upper edge of the locking cam facing the screw cap, then a clear locking is ensured, even if the axial position of the screw cap varies in the closed end position.
  • the latching flap can also be pressed inwards when passing the latching cam.
  • locking cams and locking tabs is designed so that the locking cam extends as a circular web over part of the circumference of the container neck or the pouring spout of the lower closure part, that the concave inner side of the locking cam facing the cap jacket is arranged at a short distance from the cap shell, that the Locking cams in the unscrewing direction of the screw cap in the approximately radially oriented contact surface ends in such a way that the end face of the latching tab ends in the approximately radially oriented counter-stop surface, and that the counter-stop surface of the latching tab in the latched position at least partially covers the contact surface of the latching cam by a clear one Function in the unscrewing and unscrewing direction of the screw cap.
  • the concave inside of the locking cam is provided with a deflection bevel at the inlet end opposite the contact surface.
  • the childproof lock according to the invention can also be used with a closure which is characterized in that the lower closure part is closed by means of a sealing plate which is connected to the inner wall of the pouring spout via predetermined breaking points, and that the cap jacket is connected to a guarantee ring via tear-off webs.
  • the provided with locking lugs and with counter-locking lugs of the pouring spout or a base part of the lower part of the closure so that the guarantee ring slides in the screw-on direction of the screw cap over the counter-locking lugs of the pouring spout or the base part, but is non-rotatably held in the unscrewing direction of the screw cap, and with one Closure which is designed such that the lower closure part has a U-shaped base part which can be connected to a container opening and to which a bellows is connected in one piece, so that the bellows is connected in one piece to the pouring spout, so that the pouring nozzle of a pushed home position to an extended pouring position can be brought, and vice versa.
  • the closure according to the embodiment shown in FIGS. 1 and 2 consists of a screw cap 10 and a lower closure part 20.
  • the screw cap 10 consists of a cap base 11 and a cap jacket 12 with an internal thread 13.
  • the lower closure part 20 has a U-shaped cross section Base part 21 with which the lower closure part 20 can be snapped onto a container opening provided with a locking edge.
  • a spout 22 with an external thread 23 adjoins the base part 21, so that the screw cap 10 can be screwed onto and off the pouring spout 22.
  • the pouring spout 22 is closed by means of a sealing plate 24, which is removed when the closure is opened for the first time.
  • the sealing plate 24 is formed on the inner wall of the pouring spout 22 via a circumferential predetermined breaking point 25 of small wall thickness.
  • a handle 26 is formed, which is gripped and pulled to tear the sealing plate 24.
  • a locking tab 14 is formed in such a way that it projects outward approximately tangentially from the cap jacket 12, as shown in FIG. 2. It protrudes against the screwing direction on the cap jacket 12.
  • a web-shaped locking cam 28 directed towards the screw cap 10 is formed on the horizontal section of the base part 21, a web-shaped locking cam 28 directed towards the screw cap 10 is formed. As shown in FIG. 2, this locking cam 28 with its concave inside is at a constant, small distance from the outside of the cap jacket 12.
  • the locking cam 28 is circular-arc-shaped and extends over part of the circumference of the base part 21.
  • the locking tab 14 ends in one end on its end face Counter contact surface 15, which is aligned approximately radially, while the end of the locking cam 28 lying in the screw-on direction forms a contact surface 30, which is also aligned approximately radially.
  • the latching tab 14 protrudes so far from the cap jacket 12 that it securely partially covers the contact surface 30 of the latching cam 28 in the latching position with its counter-abutment surface 15 in order to obtain a clear latching connection which only acts in the unscrewing direction of the screw cap 10.
  • the concave inside of the locking cam 28 is provided on the insertion side acting in the screw-on direction with a deflection bevel 29, so that when the screw cap 10 is screwed on, the locking tab 14 is continuously deflected inwards and can pass through the locking cams 28. To Passing the locking cam 28, the locking tab 14 automatically sets itself into the locking position shown in FIG. 2 due to its inherent elasticity.
  • the locking tab 14 If the locking tab 14 is pressed inwards manually or by means of a tool, then it gives up its locking position and can also pass the locking cam 28 in the unscrewing direction if the screw cap 10 is simultaneously rotated in this direction.
  • This child safety device from locking tabs 14 and locking cams 28 can also be used with a closure in which the screw cap 10 is provided with a guarantee ring or in which the lower closure part carries an extractable and compressible bellows between the base part and the pouring spout.
