  • the piercing spike is arranged on the inside of the closure cap and is only applied to the container neck to the extent that the tip of the piercing spike is spaced from the membrane during production of the delivery condition. Once the closure is completely applied, the membrane is pierced by the piercing spike, whereby the use state is established.
  • a removable spacer ring is used, which is mounted between the container shoulder and the underside of the cap and the full application of the cap initially prevents existing spacer ring.
  • the spacer ring is obtained by the removal as a waste product. Moreover, it is disadvantageous that the removal of the spacer ring requires a certain manual skill of the consumer, which can not be assumed in many people.
  • the disadvantage here is that the overcoming of the locking connection results in a jerky movement of the closure cap towards the container, which is stopped by the meeting of the internal thread of the cap on the external thread of the container neck.

  • the edge of the outlet opening 16 and the raised portion 14 deform elastically, and a particularly good sealing closure is formed.
  • the hinged lid 18 has at its edge region 19 in the closed position downwardly facing tongue 20 with an inwardly extending locking projection 22.
  • the locking extension 22 engages in the closed position in the manner of a snap closure, an outwardly extending locking element 24 which is formed within a rectangular recess 44, 45 on the outer wall 46 of the closure cap body 10.
  • the hinged lid 18 preferably made of polypropylene tongue 20, which has a certain elastic deformability, pulled manually outwards, whereby the locking projection 22 is released and the hinged lid 18 opens.
  • the hinged lid 18 has at its edge region 19 a downwardly facing tongue 20 with an outwardly extending locking extension 38.
  • the locking extension 38 engages in a closed position (not shown) in the manner of a snap closure, a biased inwardly extending locking element 42 which is disposed in an approximately rectangular recess 44 in the outer wall 46 of the cap body 10 and into which the tongue 20 extends.
  • an elastically deformable portion 26 is formed, which in turn preferably consists of TPE.
  • an actuating button 48 is arranged in the lower part and the locking element 42 in the upper part.
  • FIG. 10 shows the upper part of the closure according to the invention designed as a closure cap in conjunction with the lower part in the first position.
  • the closure cap essentially corresponds to the embodiment of the closure cap shown in FIGS. 7 to 9.
  • the design of the lower part 101 corresponds to the lower part described in Example 1.
  • the projection 114 is in the first position 125.
  • the lower end of the auxiliary device is located near the position 135 of the sealing element, but does not touch it.
  • the elastically deformable element 26 in the exemplary embodiment of FIG. 10 consists of a press-on tongue 80, which in a contact region 81, which preferably consists of an elastic material, in particular TPE, is connected to the outer wall of the closure cap body 10, and preferably has a spring tongue 82, which is also connected in the contact region 81 with the outer wall of the closure cap body 10.
  • a pressure on the pressing tongue 80 moves under elastic deformation of the spring tongue 82 which is arranged here on the Anpresszunge 80 locking element 24 inwardly and releases the locking projection 22 of the arranged here on the hinged lid 18 tongue 20, whereby the hinged lid 18 opens.
  • the closure cap has a web 85 over which the elastic element 30 is tensioned. The web 85 can increase the tension that occurs in the closed position of the hinged lid in the elastic member 30, whereby the opening movement of the hinged lid is supported.
  • FIG. 11 shows the upper part of the closure according to the invention designed as a closure cap in conjunction with the lower part in the second position of the auxiliary device.
  • the design of the lower part 101 corresponds to that described in the embodiment 1 and the lower part shown in Fig. 10.
  • the projection 114 is in the second position 126.
  • the lower end of the auxiliary has completely passed through the position 135 of the sealing element.
  • the substantially hollow cylinder-like auxiliary device 140 has an upper region 141 with a larger outer diameter compared to the lower region 142. Between the two regions 141 and 142 there is a middle region 143, in which the region 141 to the region 142 preferably tapers conically.
  • auxiliary device 140 The advantage of this design of the auxiliary device 140 is that a better sealing of the two parts in the region of the outlet opening 99 of the container or in the region of the passage opening 134 can be achieved when connecting the upper part 104 to the lower part 101. As a result, the contents of the container is better protected in use.
  • the auxiliary device 140 is formed substantially as a hollow cylinder which is cut at its lower end by a plane whose normal forms an angle of about 25 ° with the axis.
  • this angle has a different size, preferably forming an angle of 20 °, preferably an angle of 15 °, preferably an angle of 30 ° and preferably an angle of 35 °.
  • the advantage of this design of the lower end of the auxiliary device 140 is that the auxiliary device not only exerts a pressing force on the sealing element when piercing the sealing element, but also performs a cutting operation by the blade-like design of its lower end, which in particular means the separation of a foil-like sealing element simplified.
  • the cutting operation is based on the structural feature of the guide 115, in addition to a translational at the same time a rotational movement of the upper part and its associated auxiliary device is effected in the third guide portion 133 relative to the lower part.
  • the hollow cylinder of the auxiliary device forms a channel through which the filling material can pass from the outlet opening 99 of the container and out of the passage opening 134 of the lower part in the second position of the upper part with the hinged lid 18 open exit the outlet opening 16 of the cap (the upper part). Due to the tight connection of the upper part with the container in the region of the outlet opening 99 and by the resealable closure cap which reliably seals the outlet opening 16 in the region of the extension 34, a closure is provided according to the invention which is particularly safe and comfortable to use.
