Definitions

  • the invention relates to a closure system for a mouth having container according to the preamble of claim 1 and a method for closing a container having an orifice by means of a Verschworthsystems of the type mentioned here according to the preamble of claim.
  • Closing systems and methods for closing containers are known ( US 2,141,856 A ).
  • Known closure systems have a closure cap which engages over the mouth of the container and is provided with a bottom and a jacket extending therefrom.
  • a guarantee ring is provided, which is connected thereto via a predetermined breaking line and preferably at least one vertical incision, so a Materialschwownungsline extending over the height of the guarantee ring, that is substantially transverse to its circumferential direction and designed is that the warranty ring can rip here has.
  • the guarantee ring is used to indicate a first opening of the container and tampering with the cap, so that consumers have control over the integrity of the sealed container.
  • Containers of known closure systems have a wall portion surrounding the mouth on, which is at least partially overlapped by the jacket of the cap.
  • Known closure systems have closure caps, which are connected via a thread, possibly via a bayonet lock, with the container to be closed, or those that hold a plug inserted into the mouth of the container.
  • the guarantee ring is thereby burst open, that the cap is displaced in the direction of its axis of rotation during the first opening of the container and that corresponding barbs or the like are provided, which burst open the guarantee ring when unscrewing the cap.
  • at least one cam which projects beyond the outer circumferential surface of the wall section surrounding the mouth is provided. This is located in the area of the guarantee ring and is encompassed by this laterally.
  • the circumferentially-seen lateral boundary surfaces of the cam can engage the guarantee ring when the closure cap is rotated. So it is realized a positive connection.
  • the cam is arranged in the region of the bottom of the cap facing away from the edge of the guarantee ring.
  • the closure cap Upon rotation of the cap of the cam urges the guarantee ring so far outward that it is blown up. The tearing of the guarantee ring is facilitated by the at least one weakening line, referred to herein as a vertical cut.
  • the closure cap By breaking open the guarantee ring, the closure cap can be readily removed from the mouth of the container, that is to say from the wall section addressed here, by carrying out an axial relative movement between the closure head and the wall section.
  • the cam is thus used to Warranty when expanding the cap to widen, preferably burst. Closing systems of this type are relatively expensive and therefore expensive to implement.
  • the object of the invention is therefore to provide a closure system that is simple and inexpensive to produce without affecting the safety features of the guarantee ring.
  • a closure system which comprises the features mentioned in claim 1. It is characterized in that the closure cap in the attached state in the region of the edge facing away from the bottom is umbördelbar, so that the crimping area laterally engages around the outer peripheral surface of the wall portion surrounding the mouth projecting cam. It is not necessary that between the cap and wall portion which surrounds the mouth of the container, a thread is provided, which substantially simplifies the production of the closure system and thus makes cost.
  • the locking system is therefore particularly user-friendly, because a rotation of the cap in both directions, ie in the counterclockwise direction and allows a bursting of the guarantee ring.
  • the container is closed by means of a plug and the cap is placed over this plug and thus placed on the mouth of the container.
  • the bottom of the cap covers although the mouth of the container, but between the bottom and the mouth of the plug is arranged, which closes the container.
  • Known methods for closing a mouth-containing container by means of a known closure system include the following steps: The closure cap is placed on the mouth of the container, wherein the closure cap is then pressed. These methods are also expensive and therefore expensive to implement, especially when a thread is formed in the casing when pressing the cap, which meshes with a thread provided on the container.
  • the object of the invention is therefore to provide a method that does not have the disadvantages mentioned.
  • a method which shows the features mentioned in claim 9. It comprises the following steps: The cap is placed on the mouth of a container and pressed, for example by means of a plunger. The lower free edge of the cap, so the edge of the guarantee ring is crimped, so deformed in the direction of the surrounding the mouth of the container wall area. However, no such deformation is performed in the region of the cam, so that the guarantee ring laterally engages around the cam. This ensures that upon rotation of the cap of the cam expands the warranty ring, preferably bursts.
  • a plug is first placed on the container and then slipped over the cap.
  • the first step of the above method namely the placement of the cap is realized on the mouth of a container.
  • the remaining steps then follow, as mentioned above.
  • FIG. 1 shows a closure system 1 for a mouth having container 3, of which here a mouth surrounding wall portion 5 is shown, which is at least partially overlapped by a cap 7.
  • the closure cap 7 has a base 9 spanning the mouth of the container, to which a jacket 11 adjoins, here to the left. With this a guarantee ring 15 is connected via a predetermined breaking line 13.
  • the predetermined breaking line 13 has here in the circumferential direction of the closure cap 7 extending slots 17 which each adjoin with their ends to webs 19 which extend between the guarantee ring 15 and the shell 11 and are so narrow that they secure the guarantee ring 15 on the shell 11th hold, but a pivoting movement of parts of the guarantee ring 15, which will be discussed in more detail below, allow.
  • the predetermined breaking line 13 can also be realized by a material weakening, so by a linear area of reduced wall thickness.
  • the guarantee ring 15 has at least one, in the embodiment shown here a plurality of vertical incisions 21, 21 'which extend transversely to the circumferential direction of the guarantee ring 15, ie approximately parallel to the central axis 23 of the part of the container 3 and the cap 7 shown here.
  • the vertical incisions 21st , 21 ' serve to weaken the material of the guarantee ring and allow it to be blown open in the area of the vertical incisions 21, 21'.
  • the vertical incisions can be realized by a material weakening, ie by a region of lesser wall thickness, but also by a cut in the material of the guarantee ring 15.
  • the term "vertical incisions" thus only serves to address tear areas in the guarantee ring 15 and not to determine the realization of these areas.
  • a cam 25 is provided here, which the viewer of FIG. 1 facing and in the region of the bottom 9 of the cap 7 facing away edge 27 of the guarantee ring 15 is arranged. It is provided at its circumferentially located side edges with run-on slopes 29, 29 '. The side edges thus go over at an acute angle in the peripheral surface 24 of the wall portion 5.
  • the cam 25 is preferably an integral part of the wall section 5. However, it is also conceivable to set up a separate cam on the wall section 5 or engage in it in such a way that, as shown here, it protrudes beyond the peripheral surface 24. Seen transversely to the circumferential direction of the wall portion 5, the cam 25 has a width which is designed so that it is arranged in any case in the region of the edge 27, even if measured in the direction of the center line 23 height of the shell 11 varies production-related.
  • the cam 25 on the one hand extends slightly beyond the edge 27 under the guarantee ring 15 and on the other hand protrudes significantly beyond the edge 27 on the other hand.
  • FIG. 1 also clearly shows that on the observer facing top 31 of the cam 25, the edge 27 of the guarantee ring 5 is not crimped.
  • the wall of the guarantee ring 15 is thus substantially integrally formed on the outer contour of the cam 25, so that the edge 27 abuts against the run-on slopes 29, 29 'of the cam 25 and this is seen from the guarantee ring, circumferentially, laterally encompassed.
  • the guarantee ring 15 has a range in which the cam 25 without a - too - - stretching of the ISierings can be accommodated and that the cam 25 is laterally encompassed by the wall of the guarantee ring 15, so that a positive connection is realized. It is not absolutely necessary that the edge 27 of the guarantee ring 15 bears directly on the chamfers 29, 29 'of the cam 25 It is also conceivable that a distance between the guarantee ring 15 and the chamfers 29, 29' is given. It is crucial that the cam 25 can partially engage under the guarantee ring 15, without this being damaged. In adjacent areas, however, the edge 27 of the guarantee ring 15 approaches the peripheral surface 24 of the wall portion 5, so that the closure cap 7 can not be easily twisted.
  • FIG. 1 shows the closure system 1 in the closed state, that is, the guarantee ring 15 is intact
  • FIG. 2 shows the closure system 1 after FIG. 1 , but in open condition. Like parts are given the same reference numerals, so to the description FIG. 1 is referenced.
  • FIG. 2 clearly shows that the guarantee ring 15 is blown up, that is, the at least one vertical incision 21, 21 'is torn and lying between two adjacent vertical incisions ring segments of the guarantee ring 15 are pivoted viewed from the peripheral surface 24 of the wall portion 5 to the outside.
  • FIG. 2 clearly shows that the slots 17 thereby change their contour. In particular, the slot located in the region of a split perpendicular incision is significantly widened.
  • the ring segments of a guarantee ring 15 which lie between two vertical incisions are also pivoted in the outward-swiveled outward direction Condition held by the webs 19, so that the guarantee ring 15 is held on the shell 11 of the cap 7 and removed together with this from the container 3.
  • the blown-on ring elements clearly indicate manipulations and a first opening, more clearly than a merely widened guarantee ring.
  • the breaking of the guarantee ring 15 takes place in the following way:
  • the closure cap 7 and the container 3 are rotated against each other, so that the run-on slopes 29, 29 'push the edge 27 of the guarantee ring 15 bent in the direction of the peripheral surface 24 outwards and the guarantee ring widens. is preferably blown up, which is facilitated by the at least one vertical incision 21.
  • a closure cap 7 which consists of a deformable material, preferably made of aluminum sheet, is ensured by the bent in the direction of the peripheral edge 27 that in the guarantee ring 15 by the chamfers 29, 29 'to au- ⁇ en, ie from the peripheral surface 24 away-directed forces are built, which ultimately exceed the guarantee ring 15. If the cap 7 made of a different material, it is only necessary to ensure a thinner wall section when placing them in the region of the cam 25, so that the cam 25 does not break the guarantee ring 15 when placed. The area of lesser wall thickness is then followed, viewed in the circumferential direction, by a section of the guarantee ring whose wall thickness is made thicker.
  • FIG. 2 shows, moreover, that the cam 25 projects beyond the edge 27 to the right under the guarantee ring 15.
  • the cam 25 is arranged in the region of the edge 27 of the guarantee ring 15 and that the edge can project beyond to the right and to the left in order to be able to compensate manufacturing tolerances in the production of the closure cap 7.

  • FIG. 4 shows a container 3 with removed cap in a perspective view. Like parts are given the same reference numerals, so that reference can be made to the description of the preceding figures in order to avoid repetition.
  • FIG. 4 shows the wall portion 5, from the peripheral surface 24 of the cam 25 springs.
  • the wall section 5 surrounds the mouth 33 of the container 3, which is preferably provided with an annular bead 35 surrounding the mouth 33.
  • At the mouth 33 applied end of the annular bead 35 of the cam 25 is arranged. It is clear that with attached cap 7, the lower edge 27 in the region of the mouth 33 facing away from edge 37 of the annular bead 35 can be bent or flanged and thus comes closer to the peripheral surface 24 to lie as the outer annular surface 39 of the annular bead 35th Der Diameter of the peripheral surface 24 is thus smaller than that of the annular surface 39.
  • the annular bead 35 thus provides a fastening edge for the flanged edge 27 of the guarantee ring 15, so that the cap 7 can be securely anchored to the container 3. It is clear that the container 3 in the region of the annular bead 35 has no external thread. Accordingly, it is not necessary to provide the inner surface of the closure cap 7 with a corresponding internal thread. It is therefore possible to place the closure cap 7 on the container 3 and to securely anchor it there by frictional connection, but preferably by positive locking, namely by the edge 27 of the guarantee ring 15 being bent around the edge 37 of the annular bead 35 facing away from the mouth 33 ,
  • annular bead 35 serves to anchor the cap 7 on the container 3.
  • this anchoring can also be achieved if, instead of the annular bead 35, only individual bead regions are provided which are distributed on the peripheral surface of the container 3 and each have a rim 37 facing away from the mouth 33, under which the lower edge 27 of the cap 7 can grip.
  • a continuous annular bead 35 is selected for anchoring the closure cap 7 on the container 3, because this can have a closed circumferential surface, ie an annular surface 39, so that the closure cap 7 can easily be rotated on the container 3 when the container 3 is opened shall be.
