Definitions

  • the invention relates to a kit for a cap closure for containers with a threaded neck, which has an inner and an outer cap, wherein the inner cap carries an outwardly facing knurling at its upper edge.
  • Closures consist of a metal cap which has an internal thread and which can be rotated onto corresponding containers.
  • the inner metal cap has knurling on its upper edge, whereas the outer cap has knurling on its upper inner edge. If the outer cap is turned, it slides easily over the inner metal lock and the closed container is not opened. However, if pressure is exerted on the outer cap, the inner knurling of the outer cap engages in the knurling of the inner cap and the closed cap is opened.
  • Metal closures are also known which have webs on their lower edge and are connected to a ring via these webs.
  • a such a closure is commonly referred to as a pilfer proof closure.
  • Such a closure makes it possible to control the opening of a container for the first time. When opening the closure for the first time, breaking open the webs indicates that the container has already been opened.
  • Such a closure is used in spirits and soft drinks as well as in pharmaceutical containers.
  • a closure of the type mentioned is described for example in DE-OS 29 43 548.
  • the disadvantage of these known closures is that after a long period of use it is no longer possible to securely close the containers. The knurling attached to the metal cap engages in the knurling of the outer cap, so that the closure can be opened even without exerting pressure on the outer cap. Furthermore, with these known closures it is not possible to check whether the closure is closed sufficiently.
  • the object on which the present invention is based is to propose a child-resistant closure which cannot be opened by a child's hand even after repeated use. In particular, it should be possible to control the safe closing of the container for the adult.
  • an intermediate cap can be used between the inner and the outer cap, which has knurling on its inside and elevations on its top surface, that the outer cap has elevations pointing downward on its inner bottom surface and that the knurling the intermediate cap is designed to engage in the knurling of the inner cap.
  • the inner cap is placed on the threaded neck of a container and the thread rolled on in a manner known per se and the lower edge flanged.
  • the intermediate cap is then placed over the inner cap so that the knurling of the intermediate cap engages the knurling of the inner cap.
  • the outer cap is placed over these two caps, the elevations of the outer cap being attached above the elevations of the intermediate cap.
  • the inner cap is designed as a so-called pilfer-proof closure.
  • the inner cap has a circumferential bead and its lower edge is connected to a ring via webs.
  • the lower edge of the outer cap is bent inwards and engages under the bulge of the inner cap. Due to its special arrangement, this closure makes it possible to ensure control over an unwanted opening of the container.
  • the ring connected to the lower edge of the inner cap via webs remains on the container neck when the closure is opened by breaking the webs.
  • this opening of the closure can only take place if pressure is exerted on the cover surface of the outer cap and the closure is rotated at the same time becomes.
  • the top surface of the outer cap or the top surface of the intermediate cap is curved.
  • one of the caps is axially elastic, so that this cap bends when the respective top surface is pressed and the engagement of the respective elevations takes place in one another. After the printing has ended, the elevations no longer interlock as a result of the curvature, so that there is a further functional reliability which is guaranteed even after prolonged use.
  • the elevations of the outer cap or the intermediate cap are arranged in an annular region.
  • the projections of the outer cap as triangles and the projections of the intermediate cap are formed as radial "extending teeth.
  • grip arranged on the intermediate cap teeth only between the triangles of the outer cap, when a pressure on the top surface of the outer cap It is ensured that, even after prolonged use, the outer cap can only be rotated together with the inner cap if pressure is exerted on the top surface of the outer cap.
  • the inner cap is preferably made of aluminum, the outer cap and the intermediate cap are made of plastic.
  • the outer cap and the intermediate cap are manufactured, for example, by injection molding.
  • the desired teeth, triangles or elevations can be attached in a simple manner to the outer cap and the intermediate cap and at the same time the desired structure on the other surface. Due to the production of the inner cap made of aluminum, a simple arrangement of the thread is possible.
  • the outer cap preferably has a shoulder on its inside.
  • This shoulder is preferably designed as a circumferential ring. According to this particularly be preferred embodiment, an unwanted removal of the outer cap from the intermediate cap is no longer possible.
  • the intermediate cap lies on the circumferential shoulder and thus ensures that the outer cap does not fall off the other two caps.
  • the elevations of the intermediate cap have a trapezoidal cross section, one side being chamfered and the opposite side being formed at a right angle or a slight angle to the top surface of the intermediate cap.
  • the elevations of the outer cap have two side surfaces, one side surface being chamfered and the other side surface being configured perpendicularly or at a slight angle to the bottom surface of the outer cap.
  • the respective vertical side surfaces come into contact with one another and ensure that the container is securely closed.
  • the respective beveled side surfaces slide against each other so that the container is not opened. If you exert a pressure on the top surface of the outer cap, the can no longer slide slanted side surfaces away from each other but ensure that the container is opened as desired.
  • the kit according to the invention for a cap closure consists of the inner cap 1, the intermediate cap 3 and the outer cap 2.
  • the outer cap and the intermediate cap are drawn away from the inner cap.
  • the inner cap 1 has the knurling 4 pointing outwards at its upper edge. In the lower area it has the circumferential bead 5 and its lower edge is connected to the ring 9 by means of the webs 8.
  • the intermediate cap 3 has the inside Knurling 11 on.
  • the elevations 14 are arranged on the cover surface 12 of the intermediate cap 3.
  • the outer cap 3 has on its inner bottom surface 6 the downward elevations 15 and its lower edge 13 is bent inwards. If the outer cap 2 is above the inner cap 1, the curved lower edge 13 of the outer cap 2 engages under the bead 5 of the inner cap 1. The intermediate cap 3 rests on the shoulders 7 of the outer cap, so that the intermediate cap 3 is not inadvertently can slide down. The elevations 15 of the outer cap 2 then pass between the elevations 14 of the intermediate cap 3 when pressure is exerted on the cover surface 10 of the outer cap 2.
  • the elevations 14 and the elevations 15 are arranged in an annular region.
  • the elevations 14 of the intermediate cap 3 are designed as radially extending teeth. If the outer cap 2 is rotated, it slides along the intermediate cap 3 and opening of the container is not guaranteed even when the intermediate cap 3 is applied to the inner cap 1. If one also exerts a pressure on the top surface 10 of the outer cap 2, the outer cap slides downward and the elevations 15 pass between the elevations 14 the intermediate cap. If one now rotates this outer cap while still exerting pressure on the cover surface 10 of the outer cap 2, the intermediate cap 3 is carried along, thereby also as a result of the knurling . 11 and 4 the inner cap 1 and the closure can be rotated from the container.
  • the elevations 15 of the outer cap 2 are arranged between the elevations 14.
  • the elevations 15 are arranged on the inner bottom surface 6 of the outer cap 2. If pressure is exerted on the cover surface 10 of the outer cap 2, when the outer cap 2 is rotated, the elevations 15 take the intermediate cap and the inner cap as a result of the elevations 14 and the closure can be opened.
  • FIG. 3 shows an inside view of the bottom surface 6 of the outer cap 2.
  • the elevations 15 have the shape of triangles 16 with curved base sides 17 shown here.
  • the base sides 17 can also be straight.
  • the elevations 15 have the two side surfaces 18 and 19, the side surface 18 being chamfered and the other side surface 19 being configured perpendicular to the bottom surface of the outer cap. This arrangement of the side surfaces is described below in the description of Figure 5 and Figure 6 explained in more detail.
  • the intermediate cap 3 is located above the inner cap 1.
  • the knurling 11 of the intermediate cap 3 engages in the knurling 4 of the inner cap 1.
  • the Zwisnhenkappe 3 has the curved top surface 2o.
  • the elevations 14 are shown on the top surface 2o.
  • the outer cap 2 has the elevations 15 on its inner bottom surface 6. These elevations 15 are shown in section, so that the beveled side surface 18 and the steep side surface 19 can be seen. Furthermore, the intermediate cap 3 has on its top surface 12 the elevations 14 which have a trapezoidal cross section. The side 21 of the elevation 14 is chamfered and the opposite side 22 is formed perpendicular to the top surface 12. If the closure is to be closed, the closing of the outer cap 2 corresponds to a movement of the outer cap 2 according to FIG. 5 to the left. It can be seen that thus the vertical side surface 19 of the elevation 15 abuts the vertical side surface 22 of the elevation 14 and thus the intermediate cap 3 and thus also the inner cap 1 are closed.
  • the opening of the container is to be explained with reference to FIG. 6.
  • the opening of the closure that is to say the unscrewing of the outer cap 2 corresponds to the movement of the outer cap 2 according to FIG. 6 to the right.
  • the inclined side surface 18 of the elevation 15 abuts the likewise bevelled side surface 21 of the elevation 14.
  • the outer cap 2 is pressed upwards and the elevation 15 slides past the elevation 14.
  • the mutually sloping side surfaces slide past each other. If you turn further (corresponding to a movement of the outer cap 2 according to FIG. 6) to the right, a cracking noise occurs when the elevation 15 arrives to the right of the elevation 14.
  • the adjacent elevation 14 again causes the sloping side surface 18 to slide on its side surface 21, not shown.
  • pressure is exerted on the outer cap 2 so that the inclined side surface 18 of the elevation 15 cannot slide upwards on the inclined side surface 21 , when the outer cap 2 is unscrewed, corresponding to the movement of the elevation 15 according to FIG. 6 to the right, the elevation 14 of the intermediate cap 3 is carried along and the closure can be opened.
