Definitions

  • the present invention relates to a plastic closure consisting of a lower part and one over it Hinge axis connected cover, as well as an integrity guarantee element.
  • Integrity guarantee elements on hinge locks Plastic has been known for many years. You are supposed to be one provide a high level of security for consumers by they clearly visible the integrity of the closure and thus the content in the container protected by the closure will make visible. There are a lot of them different variants known. Most closures so-called in particular on plastic containers bounced and can not be practically non-destructive remove from the container. With such closures, however also ensure that the lid in front of the First use has not already been opened and therefore one Part of the content removed or third substances added have been.
  • Integrity guarantee elements are known.
  • a plastic closure from Expan is on the market known, the one piece on the lower part of the closure molded, vertically standing hook element shows which is closed when a pusher is closed for the first time Lid engages in a corresponding opening and at first use is separated from the lower part.
  • This A somewhat exotic example is extremely technical in terms of production complex and imperatively encourages gradual closure and demolding of the closure already in the Production mold. This can be done with tools at sixteen or practically no longer realize more cavities.
  • hinge locks are also out Plastic places ever higher aesthetic demands.
  • one trend can be identified, the two-tone one Makes closures desirable. This requires so-called two-component injection molding machines which are extremely expensive and for which there are still relatively few possible uses.
  • a Swivel hinge lock made of plastic according to the generic term of claim 1 to create the extremely inexpensive simple forms and correspondingly short Clock sequence can be injected without losing a high To have to accept rejects rate.
  • a plastic closure to create its integrity guarantee element may have a different color than the rest of the closure and thus increased individualization and one has improved visual control for the consumer.
  • a hinge lock triggers all of these tasks Plastic with the features of claim 1.
  • the closure itself can be part of a Be container, the lower part of the container part itself corresponds or, as usual, can be screwed on or pop-up connector with a container represent.
  • closures that are on Containers, in particular containers made of plastic be put on.
  • FIGS. 1-4 A first embodiment variant is shown in FIGS. 1-4 shown.
  • the closure which is designated as a whole by 1, comprises, as usual Lower part 2 and a cover integrally connected to it 3, which is connected to the lower part 2 via a pivot hinge 4 connected is.
  • the lower part 2 has a cylindrical Shell surface and has means for on the inner surface Detachable or partially detachable connection with a container. In the example shown here, an internal thread 6 is provided.
  • the lower part 2 is closed by a cover surface 8.
  • the cover surface 8 is through a pouring opening 5, for example in the form of a spout.
  • the Spout 5 is through an annular pin on the Closed inside surface of the lid 3.
  • This pouring gasket 7 can be attached to the inside as well as outside Seal the pouring spout.
  • Integrity guarantee element 10 As a separately manufactured part there is a Integrity guarantee element 10 shown which the shape of a closed ring or tire.
  • the Integrity guarantee element 10 can consequently both be made of a different plastic than the closure 1 itself and it can, of course, give an increased signaling effect produce a different color than the color from which the closure 1 is made itself. To do this visually symbolize, the tamper-evident element 10 was in Cross section shown in black. More detailed the constructive design of the integrity guarantee element 10 in Figure 4 recognize. It consists of an actual band 11, which is an upper, perpendicular from Band protruding contact surface 12 and a circumferential, has lower flexible retaining edge 13.
  • the flexible Retaining edge 13 can in principle be made such that this at the same angle which he now follows to the belt surface 11 protrudes above, is formed protruding downwards. Between volume 11 and the flexible retaining edge 13 is then a thin point present, the upturning of the retaining edge 13 allowed.
  • Such an integrity guarantee element leaves from above over the closure, whereby during the Slip the flexible retaining edge 13 upwards is redirected.
  • Mandatory for such a configuration of the Integrity guarantee element 10 is the presence of outwardly protruding parts on lid and lower part. This can, as shown here, completely or partially circumferential decorative beads, as can be seen in particular from the Figure 4 emerges.
  • the tape 11 is both in this case positively embracing the two decorative beads as well the flexible retaining edge 13 as a non-positive on Closure kept.
  • Regarding the destruction of the Integrity guarantee element 10 by means of the tab 14 will look at the different ways they work in the Figures 16-19 to be described below are shown are referred.
  • the second embodiment, as shown in Figures 5-10 is again an embodiment that allows many variations.
  • the actual closure 1 corresponds completely to that in the external design Closure according to Figures 1-4.
  • the plastic closure which in turn is made in one piece, also has the Lower part 2 and one connected to it via a hinge 4 Cover 3. Again, the top surface 8 is through penetrates a spout-shaped spout 5.
  • the top surface 8 with a peripheral peripheral Depression 15 has at least one, however, advantageously three or more passages 16. This Passages 16 pass through the top surface 8.
  • the real thing Integrity guarantee element 10 is essentially one clasp-shaped, practically any wrap angle around the clasp 1 forming clasp. Only the area of the hinge 4 must be left free clasp-shaped band 11 of the tamper-evident element 10 is via predetermined breaking points 17 with a holding element 18th connected. The diameter of the annular holding part 18 corresponds exactly to the outer diameter of the cylindrical Closure 1. The predetermined breaking points 17 are in niches 19 the holding part 18 is integrally formed.
  • the real thing, here clasp-shaped band 11 can in a variety of ways enter into a positive connection with the cap. In here shown example takes hold of the execution 5 and 10 a peripherally directed outwards Cam 30 on cover 3, band 11.
  • the band 11 overlaps the band 11 a pusher 31 and thus prevents the opening without removing the tamper-evident element.
  • the band is in the range of Pushers designed accordingly narrower. It is possible but also, the tape with hooks towards the lid provided in corresponding niches in the cover wall intervention.
  • the connection of the Holding part 18 on the lower part 2 of the closure can very different types. For example, is the Spout 5 relatively large, so the ring-shaped Holding part 18 is also positive and / or non-positive hold this spout 5.
  • This embodiment is not particularly advantageous only that in turn the integrity guarantee element in color can be designed completely independently of the closure, but in addition that the holding part 18 even after the Removal of the band 11 as a clearly recognizable color ring remains.
  • This color ring can only be used Serve decoration, but it can also be used as a color code to be needed.
  • a typical example would be here Hair shampoo, where can be indicated by the color code whether this is an anti-dandruff shampoo, a shampoo for oily hair or a shampoo for normal hair. But it would also be applicable for closures on tubes, at for example the color code information about the Fat content of a mayonnaise.
  • the guarantee element of integrity 10 once as a closed annular band and on the other hand shown as an open band-like band.
  • the band was through Holding part held in the desired end position.
  • the integrity guarantee element 10 as a resilient Clasp 110 and 114 realized.
  • the clasp can be closed in a first spread position be kept as this is the execution after 11-13 shows or the clasp can be closed in the first Condition in a compressed position be held, as is the variant according to FIGS. 14 and 15 shows.
  • These two basic types can of course be used again in various creative ways Manufacture shapes, in particular the width of the clasp-shaped Band can vary depending on the height of the closure. Furthermore, the wrap angle of the clasp vary and finally the means for positive connection of the clasp 110, 114 with the upper part or cover can be designed differently.
  • an integrity guarantee element in the Shaped a clasp shown in the first closed Condition resiliently held in a spread position is.
  • a closure 1 in can be seen in FIG. 11 above supervision in the closed state.
  • the separate Integrity guarantee element 10 is not included in it shown assembled state.
  • the unloaded clasp-shaped Integrity guarantee element 110 has in unloaded state has a diameter that is smaller than the diameter of the closure 1.
  • To assemble the clasp-shaped band can this from the front on the Clasp can be pressed open, the clasp-shaped band 110 must be spread at the same time.
  • the clasp-shaped Band 110 for example, faces inward Form-fitting parts 111, which have predetermined breaking points 112 the band-shaped band 110 are connected.
  • the closure 1 needs appropriately arranged intervention options 113, in which the form-fitting parts 111 in the first closed Intervene state or state of integrity.
  • This form fit is designed so that the Do not let form locking parts 111 disengage.
  • the predetermined breaking points 112 must therefore only be opened for the first time be severed. Because the band-shaped band 110 den Clasp 1 can encompass less than half the circumference it doesn’t just snap onto the clasp become. Precisely the pre-tension under which the tape on Closure is held over the predetermined breaking points make sure after cutting the Predetermined breaking points irreversible the guarantee element of integrity is separated from the closure.
  • the band 114 with one protruding outwards Holding collar 115 provided.
  • the holding collar 115 is over a Breakage point 116 connected to band 114.
  • the predetermined breaking point 116 is here, for example, as a predetermined breaking seam realized.
  • the holding collar 115 is dimensioned so that it via a protruding from the top surface 8 of the closure Shell wall of the lower part 2 held in a form-fitting manner is.
  • Both on the inner wall of the lower part and on the Inner surface of the cover 3 are positive locking means 117 in the The shape of nose-shaped projections or recesses is provided, which with correspondingly opposite parts 118 am Match volume 114 together.
  • Such an integrity guarantee element can be easily opened on the Mantle wall of the lower part 2 or the lid 3, depending on Design, put on, after which the closure 1 is closed can and the positive locking means 117, 118 engaged come. Is then by pulling the tab 14 after torn outside collar 115, so is the tape 114 no longer held and relaxes within the Lock and jumps from the position 114 'in the position 114 ", as indicated in FIG. 14. In the unloaded The form-locking means 117, 118 are then no longer in a state engaged with each other and the lock can be opened.
  • a solution can be used in much the same way be in which the integrity guarantee element an in Cross-section has an approximately Z-shaped shape, as shown in the figure 15c shows. With this variant, the required Shape the form-fit agent 118 particularly well. something similar also applies to the variant according to FIG. 15d.
  • FIG 16 shows a closure with tamper-evident element 10 approximately according to an embodiment as shown in Figures 1-3.
  • Band 11 is tight fits over the closure and has a window 160, through which, for example, pusher parts on the lower part and reach through lid 2,3. Starting from this window 160 runs circumferentially in the longitudinal direction Partition strip 161, the. On both sides by predetermined separation points or Target seams is limited. This is after in vertical section of Figure 17 clearly recognizable. At least one-sided A tab 14 is formed on this separating strip 161. By The separating strip 161 can be pulled on this tab 14 tear out and the tape 11 irreversibly breaks into two Subbands. Such a band 11 can be relatively strong be subjected to tensile stress without this causing the predetermined breaking points 162 will be affected. Accordingly, it can Volume 11 not only one in the guarantee of integrity positive but also a non-positive component perceive.
  • the stretchable or stretchable Band area 190 is delimited by predetermined breaking lines 17.
  • a Tab 14 is via bendable, bow-shaped webs 192 to the fixed lateral ends of the stretchable band section. By pulling on the tab 14, the predetermined breaking points can be 17 perpendicular to the direction of the band 11 without problems separate. Because small webs in the area of the predetermined breaking points the direction of the tape run are present with very small Cross section, the molecular chains in this area directed and accordingly these webs keep relatively high Tensile forces in the direction of the webs respectively of the molecular chains. By pulling on the tab 14, however exerted a force perpendicular to this direction, whereby a notch effect takes place on the molecular chains and accordingly the predetermined breaking points can be easily separate.
  • the integrity guarantee elements according to the invention can also be made particularly large. Get through it they have an increased signal effect. This signal effect leaves stand out extremely in that the integrity guarantee element easily in another color or can be made of a different material than that Closure. Without the expensive purchase of a two-component spraying machine can be a two-tone plastic closure achieve the highest aesthetic requirements can suffice.
