Definitions

  • the invention relates to a tamper-evident lid for a container, the container comprising an opening edge which runs around an upper container opening and is in particular flanged with a lid piece essentially covering the upper container opening, and a lid edge running essentially downwards from the lid piece towards the container, comprising, at least in some positions, a locking element which grips below the opening edge, which may be definitely separated from the lid in particular together with a lower edge end section of the lid edge for removal of the lid from the container.
  • Such a lid is known from U.S. Pat. No. 5,002,198.
  • the corresponding lid piece is placed on the opening edge from above and covers the container opening.
  • This lid piece is connected to the lid edge extending from the lid piece vertically downwards.
  • the lid edge essentially tangentially abuts the curled or flanged container edge, and a locking element projects from its free end and ends below the opening edge essentially gripping below the same.
  • a portion of the lid edge and in particular a lower edge end section is separated together with the locking element. Subsequently, the lid can be removed from the container.
  • the definite separation of the edge end section with locking element from the rest of the lid essentially ensures that even if the lid is still or again placed on, one can find out whether the same had been already removed by another user or was at least prepared for removal. This permits to detect any manipulation or any attempt of breaking open or opening the container.
  • Such a lid can, for example, prevent that the corresponding container is opened, the contents is somehow influenced or else partially taken out and the container is subsequently closed again without the opening of the container being identifiable from outside.
  • the vertically extending lid edge can be only slightly elastically deflected, so that when the lid is being placed onto the container, the locking element has to have a correspondingly high elasticity so that it can be sufficiently deflected radially outside in the region of the opening edge curled outwards.
  • This relatively high elasticity of the locking element permits a corresponding manipulation for removing the lid in that due to this relatively high own elasticity of the locking element the same can be more easily deflected outwards and the lid can then be removed from the container.
  • the invention is in particular characterized by the lid edge extending essentially inclined downwards and outwards from the lid piece and the locking element being designed as locking edge running in the circumferential direction of the lid.
  • the corresponding locking edge can not be brought into an essentially vertical arrangement without simultaneously manipulating the lid edge in order to possibly remove the lid from the container. Instead, by the inclined arrangement of the lid edge, the corresponding locking edge is held in a certain inclined position even if it abuts the lid edge from the inside, so that it is almost impossible to shift it past the opening edge for removing the lid without any visible traces.
  • the corresponding lid piece it is possible for the corresponding lid piece to have various shapes.
  • the geometric shape of the lid piece along the opening edge essentially corresponds to the shape of the container opening.
  • the lid piece is, for example, curved, buckled or deformed in any other way towards the inside of the container, or else that it is correspondingly deformed away from the container.
  • a simple lid piece that is also easy to manufacture can be essentially plane. It then rests on the container edge and covers the complete container opening in order to secure the same against external influences and simultaneously seal the contents of the container.
  • the lid piece can comprise an edge flange running in the circumferential direction and essentially vertically projecting upwards.
  • the lid edge can be directly connected to the plane lid piece or else to the edge flange.
  • the lid edge comprises an essentially inverted U-shaped upper edge end section, the edge flange being inserted into the U-opening and fixed there.
  • the depth of the U-opening can essentially correspond to the vertical length of the edge flange.
  • the edge flange is gripped on both sides by the corresponding U-legs of the upper edge end section and can, for example, be fixed to them by gluing, heat sealing or otherwise.
  • the lid edge can comprise between the upper edge end section and its lower end at least one upper and one lower edge section which extend each inclined outwards away from the lid piece and which are then connected by an essentially vertical intermediate edge section.
  • This intermediate edge end section can serve in particular for abutment with the opening edge from the outside, so that the lid itself can be securely placed onto the container and held there even if the edge end section is definitely separated.
  • This essentially stepped inclined extension of the lid edge results in an optically advantageous appearance for the lid, and the lid can be more easily gripped and placed onto the container.
  • the already mentioned lower edge end section can in this connection be designed such that it essentially vertically extends between the lower edge section and the lower end of the lid edge. This results in the space between the lower edge end section and the container wall being smaller than in case of an inclined extension of this lower edge end section, so that there is less space for possible manipulations.
  • the essentially vertical extension of the intermediate edge section and the lower edge end section can also be replaced by a certain inclined extension of these sections, these sections extending inclined outwards with a smaller angle of inclination than the upper and lower edge sections.
  • a stabilisation of the lower edge end section and thus equally a stabilisation of the locking edge can result by designing at least the lower edge end section with two layers, i. e. an outer and an inner layer. Thereby, this lower edge end section has an increased stiffness which on the one hand complicates its manipulation for removing the lid and on the other hand reinforces the locking edge.
  • the locking edge can be designed as prolongation of the inner layer. In this case, it simply extends in prolongation of the inner layer towards the container in order to grip below the corresponding opening edge.
  • the locking edge can project directly as prolongation of the inner layer in the region of the lower edge end section.
  • this inner layer can extend at least partially to the lower edge section and for the corresponding angle of inclination of this edge section to serve for deflecting the inner layer and thus the locking edge towards the container wall.
  • the angle of inclination of the lower edge section can equally be continued in the locking edge, so that this extends inclined upwards towards the container wall when the lid is placed on and grips below the opening edge.
  • the elasticity for deflecting the lid edge and the locking edge and thus for placing the lid onto the container is distributed to the lid edge and the locking edge.
  • the locking edge is an advantage for the locking edge to be elastically deflectable radially outwards. This at least concerns the portion of the locking edge projecting from the lower edge section or the lower edge end section, respectively.
  • the locking edge can have at its free end an end edge of cut essentially extending in parallel to the container wall when the lid is placed on. This end edge of cut can also directly abut the container wall when the lid is placed on. The corresponding extension of the end edge of cut complicates a spreading and thus passing by of the free end of the locking edge at the opening edge.
  • a tear device can project from the lid edge. It is also possible that more than one tear device is arranged.
  • the tear device can, for example, approximately perpendicularly project from the lid edge, so that it can be easily gripped laterally of the lid edge and can then be used for separating the corresponding portion of the lid. It is also possible that the tear device extends in prolongation of the lid edge at its lower end.
  • an essentially vertical tear aid can be formed in the lid edge. If the tear device is then gripped and moved into the tearing direction, first the lid edge is ruptured along the vertical tear aid, and subsequently a further separation of the corresponding portion of the lid edge essentially in the circumferential direction is effected.
  • Such a tear aid can have various designs. In general, it is designed as material weakening line.
  • a material weakening line can be a material thinning, a perforation or the like.
  • an edge tear-off aid extending in the circumferential direction can be formed essentially perpendicularly to the tear aid in the lid edge spaced apart from its lower end. This aid intersects the perpendicular tear aid, so that when the tear device is moved into the tearing direction, after the rupture of the tear aid subsequently the further separation of the corresponding portion of the lid edge is effected along the edge tear-off aid.
  • the edge tear-off aid can be designed as material weakening line similarly to the tear aid.
  • the edge tear-off aid can be arranged closer to the lower end of the lid edge than the opening edge when the lid is placed on the container. This ensures that after the corresponding portion has been torn off, a sufficient portion of the lid edge remains for it to essentially extend over the opening edge downwards and a replacing of the lid and secure holding of the lid at the container is possible.
  • the lid can be completely or only partially made of a plastic material. This can be at least partially transparent or translucent. This can in particular apply to the lid piece. Thus, the contents of the container are visible.
  • a lid easy to be manufactured and recycled can result from the lid essentially being made of one or more paper layers. Moreover, such a paper layer can be easily imprinted for advertising purposes or for giving an indication of the contents of the cup.
  • a fluid-tight plastic foil can be applied to its bottom side.
  • a plastic foil additionally prevents that, for example in case of a liquid being contained in the container, the paper layer of the lid and in particular the lid piece is soaked by the liquid and possibly optically affected.
  • the lid or one of its parts does not consist of only one paper layer, but of interconnected and in particular laminated paper layers. It was already pointed out that at least in the region of the lower edge end section the construction consists of two layers, where the inner layer forms the locking edge. Here, too, the corresponding layer can be a paper layer.
  • the lid In order to be able to store the lid in a simple manner for closing the container or after its manufacture, respectively, the lid can be stackable and unstackable.
  • Such a stackability and unstackability can be achieved, for example, by an internal diameter of the lid edge being, at least at its lower end, larger than an external diameter of the upper edge end section.
  • a corresponding relation between internal diameter and external diameter can also be present for the lower edge end section, possibly down to the region of the lower edge section which improves the stackability of the lids.
  • the locking edge can be designed as stack stop element which abuts the upper edge end section from outside and in particular from above when the lids are stacked.

  • the inner layer essentially extends following the lower edge section 16 separate from the rest of the lid edge 6 towards the container wall 24 and thereby forms the locking edge 10 as locking element 7 .
  • the locking edge 10 extends around the complete container 2 in the circumferential direction 9 .
  • a free end of the locking edge 10 grips below the opening edge 4 and is arranged closely to an outer side of the container wall 24 when the lid 1 is placed on the container 2 , or else it is possibly in abutment with the container wall.
  • the abutment of the free end 25 also see FIG. 3 , of the locking edge 10 at the outer side of the container wall 24 can be effected such that after a corresponding placing on of the lid 1 onto the container 2 , the free end 25 is further deflected by the abutment with the container wall 24 towards the opening edge 4 in order to increase the tamper-evidence of the lid 1 .
  • the deflection can be effected in this connection so far that the free end essentially at least partially engages a gap 39 between the opening edge 4 and the container wall 24 .
  • the lid edge 6 When the lid 1 is placed onto the container 2 , the lid edge 6 can be elastically radially expanded outwards at least with the lower edge end section 8 , the lower edge section 16 and the intermediate edge section 17 as well as the locking edge 10 so that it can be passed along the opening edge 4 . As soon as the free end 25 reaches the bottom side of the opening edge 4 , it is pressed towards the container wall 24 and in particular into the gap opening 39 between the flanged opening edge 4 and the container wall 24 due to the elasticity of the lid edge 6 and the locking edge 10 .
  • FIGS. 4 a to 4 c various steps of placing a corresponding lid 1 onto a container 2 are shown. In these steps, in particular the deflection of the locking edge can be seen.
  • FIGS. 4 a to c a structuring of the lid 1 on its outer side in the region of the upper edge end section 12 can be seen.
  • This structuring is formed by a plurality of indentations and elevations, respectively, arranged in the circumferential direction 9 .
  • FIG. 3 two lids 2 arranged one upon the other and being stacked are depicted.
  • an internal diameter 35 of the lower edge end section 8 is larger than an external diameter 36 of the upper edge end section 12 .
  • the locking edge 10 forms at least in the embodiment according to FIG. 3 a stack stop element 37 resting on the upper edge end section 8 of the lower lid 2 from above and essentially from outside.
  • the lower edge end section 8 and the upper edge end section 12 essentially extend vertically, so that the stacked lids are arranged one upon the other so as to precisely fit, and the lower lid is inserted into the upper lid until it approximately abuts the lower end 14 of the upper lid with the upper edge section 15 .
  • FIGS. 6 a and b as well as 7 further embodiments of a tear device 27 are shown.
  • the separable portion of the lid edge 6 is at least partially already separated.
  • the tear device 27 being essentially not formed as a separate part of the lid edge 6 but by a part of the lid edge 6 arranged adjacent to the tear line 30 .
  • the container 2 is at least partially elastic in the region of the opening edge 4 or the container wall 24 , respectively, so that the container, too, can elastically be deformed when the lid is placed on.
  • FIGS. 4 a to 7 it is in particular shown how the free end 25 of the locking edge 10 engages with the gap opening 39 between the container wall and the opening edge 4 .
