Definitions
- the invention relates to a container closure made of plastic according to the preamble of claim 1 and a container, in particular a plastic bottle with a container closure according to the invention according to the preamble of claim 16.
- the guarantee ring is connected to a screw cap with predetermined breaking webs which are arranged along its circumference.
- the screw cap comprises a cylindrical jacket and an adjoining cover disk.
- the jacket has an internal thread, so that the screw cap can be screwed onto a container neck with an external thread.
- the predetermined breaking webs connect the open edge of the cylindrical man means with the guarantee ring. If the predetermined breaking webs are severed, this indicates that the screw cap has already been unscrewed from the container at least once.
- the guarantee ring must be held on the container neck in the axial direction so that the axial distance between the guarantee ring and the screw cap can increase when unscrewing. Therefore, retaining means are formed on the inside of the guarantee ring, which engage under a retaining ring formed on the container neck and extending outward in the radial direction.
- WO 2005/077777 A1 shows an embodiment which is frequently used.
- the tamper-evident band is designed so that it can be folded over and the folded part forms the engagement means which engages under the retaining ring of the container neck.
- the folding over represents an additional work step and, on the other hand, that the material requirement for the quasi-duplicated guarantee band is high.
- retaining cams are provided on the inside of the guarantee band, which act as holding means.
- Such retaining cams are shown in WO2009 / 115443. The retaining cams must be designed in such a way that the closure can be demolded from a tool.
- US 2001/0015341 A1 discloses a plurality of holding means which are designed as flaps.
- the lower edge of the flaps is held pivotably on the guarantee ring with a film hinge in the circumferential direction.
- the upper edge is open and therefore forms a retaining edge.
- the retaining edge engages under the retaining ring of the container neck.
- the application force of the closure should be reduced, i. H. the closure should be able to be bounced open with less force on the container after it has been filled for the first time.
- Another object is to show a closure in which the material consumption is reduced, which leads to a corresponding reduction in costs.
- the invention is preferably characterized in that the guarantee ring has slots distributed over the circumference with an upper edge and a lower edge, the upper edge being formed by an arcuate section of the guarantee ring and the lower edge by an inwardly inclined in the radial direction Wall section is formed and that the lower edge of each slot forms the engagement means for a positive engagement in an abutment arranged in the region of the container neck. Since the engaging means in the form of the inwardly inclined wall sections are not fully available on the guarantee ring and there are slots, the shape of which reduces the use of material even further, the material requirement for plastic can be significantly reduced by up to 5%.
- the wall section is immovable inward in the radial direction, as a result of which the guarantee ring is held on the retaining ring and can only be pulled over it when the guarantee ring is stretched around its circumference.
- the guarantee ring is held so tightly by the wall sections on the retaining ring that the first predetermined breaking webs reliably tear before the bracket of the wall sections is overcome.
- the wall sections are flexible or movable. As a result, the wall sections can be removed from the injection mold or the injection molding tool with little effort.
- the force for Applizier is Aufprellen of the container V er gleiches compared to the prior art, significantly reduced. A stretching of the guarantee ring, which can lead to permanent damage to the container closure, is largely prevented during demolding and bouncing.
- the Wandab section has a first section which corresponds to an inclined casing section and has two second sections which connect the first section to the casing.
- the second subsections hold the first subsection firmly and prevent it from following in the radial direction as a result of an axial unscrewing force is pulled inside. If the wall section is pressed radially outward when it is pressed open or removed from the mold, the second partial sections yield in a defined manner, since they can be deformed or compressed.
- the second subsections are oriented obliquely inwardly facing one another.
- the second subsections can be deformed in a defined manner in the circumferential direction when the wall section is pushed outward in the radial direction.
- the deformation is elastic and the wall section automatically returns to its basic position, in which it is hooked under the retaining ring.
- the lower edge corresponds to the free edges of the first section and the second section and lies in one plane.
- the lower edge has a spatial extension and not just the extension of a straight line or a line. This enables the form-fitting engagement on the retaining ring to be particularly stable and not to be released by the usual axial opening forces.
- the plane in which the lower edge lies is oriented perpendicular to the central axis of the container closure. This allows the entire lower edge to rest on the retaining ring when the guarantee ring is pulled up when unscrewing the screw cap. This form of execution therefore leads to a particularly stable form fit between the wall section and the retaining ring.
- the inclined wall sections have a wall thickness that is reduced compared to the rest of the guarantee ring, the area of the lower edge having the smallest wall thickness.
- This wall thickness kendimension ist improves the desired elastic deformability of the wall section radially outward, whereby the bounce and the demoldability of the container closure are further improved.
- the wall thickness of the inclined wall sections decreases in the axial direction starting from the free end of the guarantee ring.
- the wall thickness preferably decreases linearly. As explained in the last paragraph, this allows the desired elastic deformation of the wall Improve the cut radially outwards.
- the area of the lower edge, which protrudes the furthest radially inward can be elastically deformed outward particularly well due to the smallest wall thickness.
- slots of the same size are arranged at the same distance from one another in a circumferential section of the guarantee ring and the same number of slots is arranged in a diametrically opposite circumferential section.
- the holding force can be increased and adapted to the force which acts on the wall section when it is unscrewed.
- the diametrical arrangement of the same number of wall sections distributes the tensile force acting on the guarantee ring symmetrically on the wall sections.
- the slots are advantageously of the same length and each have an opening angle of 15 to 30 degrees and preferably between 23 and 27 degrees on the circumference of the guarantee ring, the lower edges of the slots have sufficient length for a reliable form fit on the retaining ring. Wall sections or slots with this length can be easily produced using slides of an injection molding tool.
- the invention is also preferably characterized in that the container closure has at least one retaining strap with a first and second end and a first and second longitudinal side, the first end being permanently connected to the free edge of the jacket and the second end being detachable to the guarantee ring connected is.
- the screw cap is held captive on the container or on the guarantee ring after it has been unscrewed from the container neck.
- the combination of the engagement means in the form of slots or wall sections with at least one retaining strap offers the further advantage that the guarantee strap can only be removed from the container neck by destroying it and the container closure is always connected to the container when it is disposed of.
- At least one recess is provided on the guarantee ring, in which the retaining strap is received.
- the Retaining strap requires no additional space by seeing the recess and therefore no additional plastic is required to form the retaining strap.
- the at least one recess is provided on a circumferential or ring section of the guarantee ring which is free of slots.
- the wall sections can ideally be combined with at least one retaining strap. Since the holding force of the wall sections is greatly improved compared to engagement means according to the prior art, the wall sections do not necessarily have to be formed around the guarantee ring, but peripheral sections of the guarantee ring without wall sections can also be present. These circumferential sections offer sufficient space for training we at least one retaining strap. As a result, it can be avoided that the retaining strap is arranged over the wall sections, which would inevitably lead to an increased height and increased material consumption.
- second predetermined breaking webs connect the first longitudinal side of the retaining strap to the free edge of the jacket and third predetermined breaking webs connect the second longitudinal side of the retaining strap to the guarantee ring.
- the second and third predetermined breaking webs stabilize the area around the at least one retaining strap.
- the guarantee ring can still be easily bounced onto the container neck and is not weakened in the area of the retaining strap.
- undamaged second and third predetermined breaking webs together with undamaged first predetermined breaking webs indicate the originally closed, unopened container closure.
- the combination of the above-described slots or wall sections with at least one retaining strap on the guarantee ring is ideal. This is due to the fact that the retaining strap has to tear off in a defined manner in order for it to function perfectly.
- the stable attachment of the guarantee ring to the retaining ring enables precisely this defined tearing off of the second and third predetermined breaking webs.
- the at least one retaining strap has a length such that when the screw cap is unscrewed, the free edge of the jacket can be locked in one of the slots and at least one retaining strap is retained in the slot.
- the slots therefore interact directly with the retaining strap in order to hold the screw cap on the guarantee strap.
- the advantage of this type of clamping is that it is independent of the type of clamping on the preform or is on the support ring on the container. Since the support ring can be designed to be variable in terms of diameter and its position on the container neck, clamping under the support ring has the disadvantage that the length of the retaining strap must always be specially adapted to the design of the support ring.
- the unscrewed screw cap can be held on the container closure itself and is independent of the container and its support ring and its dimensions.
- two retaining straps are provided, the length of which is dimensioned such that they pull the free edge into one of the slots when the screw cap is unscrewed, whereby the free edge is locked in the slot.
- the two retaining straps are preferably tensioned when the screw cap is held in the slot. As a result, the screw cap is held on the guarantee ring in a particularly stable and reliable manner. After using the container, the screw cap can be loosened from the guarantee ring and screwed back onto the container.
- the jacket expediently rests against the upper edge of the slot and the free edge rests against the first partial section of the wall section.
- Another aspect of the invention relates to a container, in particular a plastic bottle with a container closure according to the description above.
- the lower edge of each slot engages the retaining ring for positive engagement.
- the container closure fits on all containers, in particular plastic bottles, which have a retaining ring for the positive engagement of a guarantee ring.
- the container closure is therefore suitable for all containers that are suitable for standard guarantee closures with a guarantee ring.

- FIG. 18 the container closure in a perspective view, the screw cap being pulled into the slot by two retaining straps.
- FIGS. 1 to 12 a container closure is shown which is designated as a whole by the reference numeral 11.
- a first embodiment is shown in FIGS. 1 to 4 and a second embodiment is shown in FIGS.
- a guarantee ring, which the container closure has, is shown separately in FIGS. 13 to 16.
- the container closure 11 has a screw cap 13 which comprises a cylindrical jacket 15 and a cover disk 17 adjoining the jacket 15.
- a sealing element for example a sealing ring 18, can be formed on the inside of the cover disk 17.
- the jacket 15 has an internal thread 19 which cooperates with an external thread 21 of a container neck 23 of a container 24 (FIG. 9).
- the sealing ring 18 interacts with the open edge of the container neck 23. As a result, the container 24 is tightly closed when the screw cap 13 is screwed onto the container neck 23.
- the container closure 11 has a guarantee ring 25, which is connected to the free edge 29 of the casing 15 via first predetermined breaking webs 27.
- first predetermined breaking webs 27 break, which means that it is immediately apparent whether the container closure is originally closed or not.
- Slits 31 are provided on the guarantee ring, distributed over the circumference of the guarantee ring 25.
- the slots 31 each have an upper edge 33 and a lower edge 35.
- the upper edge 33 is formed by an arcuate section of the guarantee ring 25.
- the lower edge 35 corresponds to the free edge of an inwardly inclined wall section 37 in the radial direction.
- the lower edge 35 has a smaller radius than the guarantee ring 25 due to the inner inclination of the wall section 37 and can therefore strike an abutment of the container neck 23 when the screw cap 13 is unscrewed from the container neck 23.
- the abutment is through a Realized retaining ring 39, which is formed below the external thread 21 on the container neck 23.
- Each wall section 37 has a first section 41 and two second Partab sections 43 on.
- the first section 41 represents an inwardly folded Mantelab section and is preferably flat.
- the second subsections 43 adjoin the inwardly facing sides of the first subsection 41 and connect it to the jacket 15.
- the second subsections 43 can be curved or flat and are facing each other obliquely inward.
- the lower edge 35 of the slot 31 corresponds to the free edges of the first section 41 and the second section 43 and lies in a plane 45, which is shown in FIGS. 10 and 16.
- the plane 45 is preferably oriented perpendicular to the central axis 47 of the container closure 11.
- the inclined wall sections 37 have a reduced wall thickness compared to the rest of the guarantee ring 25.
- FIG. 10 shows that the area of the lower edge 35 has the smallest wall thickness.
- FIGS. 4 and 8 it is shown that the wall sections 37 are arranged in pairs diametrically opposite one another on the guarantee ring 25.
- FIG. 4 shows that several slots 31 of the same size are preferably arranged in a circumferential section of the guarantee ring 25 at the same distance from one another and that the same number of slots 31 is arranged in a diametrically opposite circumferential section.
- the holding forces of the wall sections are distributed as evenly as possible over the circumference of the guarantee ring 25.
- two free ring sections 49 which do not have any slots 31, are consequently provided.
- the injection molding tool for producing the container closure 11 has two slides. The slides produce the slots 31 and the wall sections 37.
- Figures 5 to 7 and in particular Figure 8 show a second embodiment in which the slots 31 or the wall sections 37 can be evenly distributed over the circumference of the guarantee ring. In this exemplary embodiment, there are therefore no free ring sections 49.
- This embodiment is preferably produced with an injection molding tool with 4 slides.
- the slots 31 are preferably all of the same length and have an opening angle 51 which is preferably 25 degrees. As a result, the lower edges 35 have a sufficient length to hold the guarantee ring 25 reliably and permanently on the container neck 23.
- FIG. 12 An exemplary embodiment is shown in FIG. 12 in which at least one retaining strap 53 is integrated into the guarantee ring 25.
- the retaining strap 53 has a first and second end and a first and second longitudinal side.
- the first end 55 is firmly or non-releasably connected to the free edge 29 and the second end 57 is firmly or non-releasably connected to the guarantee ring 25.
- the screw cap 13 is captively connected to the container neck 23 by the retaining strap after it has been unscrewed for the first time, and the screw cap 13 must therefore be disposed of together with the container 24.
- a recess 63 is hen vorgese on the free ring portion 49.
- the retaining strap 53 is received in the recess 63.
- the free ring section 49 offers sufficient space so that the retaining band 53 is integrated in the guarantee ring 25 without the height of the guarantee ring having to be increased or more material being necessary. It goes without saying that if there are several retaining straps 53, several recesses 63 are provided for receiving them.
- Second predetermined breaking webs 65 connect the first longitudinal side 59 of the retaining strap 53 to the free edge 29 of the jacket.
- Third predetermined breaking webs 67 connect the second longitudinal sides 59 of the retaining strap 53 to the guarantee ring 25.
- the intact second and third predetermined breaking webs 65, 67 like the first predetermined breaking webs 27, indicate the original closure of the container closure.
- the second and third predetermined breaking webs 65, 67 are necessary for the container closure 11 to be sufficiently stable, even if at least one retaining strap 53 is provided, to enable it to be bounced onto the container closure 11.
- the guarantee ring 25 according to the first embodiment is shown without the screw cap 13.
- the screw cap 13 is unscrewed from the Be Schol terhals 23.
- an annular bead 69 is formed on the guarantee ring 25 above the slots 31, on which the upper edges 33 lie.
- the first angle of inclination 71 indicates the inclination of the first subsection 41 with respect to the plane of the lower edge 45.
- the first angle of inclination 71 has a size between 60 and 80 degrees and preferably between 65 and 75 degrees. The greater the first angle of inclination 71, the better the stability of the wall sections 37 against vertical forces or axial tensile forces caused by unscrewing the screw cap 13. The first angle of inclination 71 must not become too large, otherwise the retaining ring 39 will not be sufficient Can be attacked.
- the second angle of inclination 73 indicates the inclination of the slot 31 with respect to the plane of the lower edge 45.
- the connecting straight line 75 which represents the inclination of the slot, is a connection of the upper edge 33 with the lower edge 35 in a plane which is spanned by the central axis 47 and the connecting straight line 75.
- the second The angle of inclination 73 is included by the connecting straight line 75 and the plane 45.
- the second angle of inclination 73 has a size between 30 and 50 degrees and preferably between 35 and 45 degrees. The greater the second angle of inclination 73, the easier it is for the container closure 11 to be removed from the mold.
- the wall sections 37 make it possible that the guarantee ring 25 is reliably held on the container neck 23, even if increased axial forces act when unscrewing the screw cap 13, which pull the guarantee ring 25 upwards. Accordingly, the predetermined breaking webs 27,65,67 reliably tear before the guarantee ring 25 is pulled over the Hal tering 39.
- the design of the wall sections 37 enables the container closure to be demolded from its tool without being destroyed and to be bounced onto the container neck 23 with a reduced application force (compared to the prior art). This is due to the fact that the Wandab sections 37 are immovable in the radial direction inwards, but have a certain mobility in the radial direction outwards.
- the combination of the slots 31 or wall sections 37 with at least one retaining strap 53 on the guarantee ring 27 offers great advantages. This is due to the fact that for the at least one retaining strap 53 to function perfectly, it must tear off in a defined manner.
- the particularly stable attachment of the guarantee ring 25 to the retaining ring 39 enables precisely this defined tearing off of the second and third predetermined breaking webs 65,67.
- FIG. 17 shows a variant of how the unscrewed screw cap 13 can be held on the container 24.
- the at least one retaining strap 53 has a catch such that the free edge 29 can be held in one of the slots 31.
- the screw cap 13 is fixed by the dimensions of the catches of the retaining strap 53, so that it does not interfere with the pouring out of filling material.
- the slots 31 and the retaining strap 53 therefore interact directly so that the screw cap 13 can be fixed.
- the slots 31 therefore have a further benefit in addition to the reliable mounting of the guarantee ring 25. Because the screw cap 13 can be held on the guarantee ring 25, a holder on the support ring 77, which is formed on the container neck 23, is obsolete.
- the holding The length of the band 53 therefore does not have to be adapted to different diameters and positions of the support ring 77, but can always have the same length.
- FIG. 18 Another embodiment is shown in FIG. 18, in which the free edge 29 is pulled into the slot by a first and second retaining strap 53a, 53b.
- the retaining straps 53a, 53b are preferably tensioned so that the screw cap 13 is held firmly on the slot 31.
- the free edge 29 is preferably drawn against the slot 31 in such a way that the jacket 15 rests against the upper edge 33 of the slot 31 and the free edge 29 rests against the first partial section 41 of the wall section 37. Because the screw cap 13 rests against an edge and a surface, the formation for particularly firm mounting of the guarantee ring 25 on the container neck 23 is also ideally used to ensure that the screw cap 13 is held firmly and wobbly on the guarantee ring 25.
