Definitions

  • a container cover is the object of the invention.
  • the present invention relates to a container cover comprising at least one safety seal device which is suitable for indicating the occurrence of the first opening of the container, and also to a method of first opening a container comprising said cover.
  • a container cover according to one aspect of the invention is a container cover also for degradable items such as, by way of non-limiting example, foodstuffs such as ice-cream, bakery or deli items.
  • Known containers which are suitable for containing also degradable items such as e.g., foodstuffs, generally comprise a various shaped receptacle, such as for example a tub or a tray, in/on which the item is housed, and a cover, in which connection means perform a shape coupling between receptacle and cover along a peripheral contact path.
  • the receptacle indeed generally comprises a projection which extends along at least one portion of the perimeter thereof and which is housed in a corresponding peripheral seat comprised in the cover, which substantially is complementary to the projection of the receptacle such as to avoid the release of said projection from said seat in order to avoid the accidental opening of the container when the container is in the closed arrangement.
  • the cover also may be provided with precut or weakened portions so as to facilitate the breakage thereof and the opening of the container, thus allowing the access to the product.
  • Known containers comprise devices which are suitable for indicating the occurrence of the first opening of the container so as to immediately inform the consumer if the container has already been opened or if it is still in its original sealed state.
  • document WO-A-2014-099368 shows a container comprising a tab of material connecting a peripheral edge of the receptacle with the cover and suitable for being removed by tearing during the first opening of the container.
  • Documents US-A-2010-089922 , EP-A-0121201 and DE-A-4418935 show solutions similar to the preceding one.
  • document WO-A-2004-013010 shows a solution of cover for a standard cylindrical container, in which said cover comprises a safety seal comprising a flexible tab which rests against a portion of the cylindrical receptacle wall so as to avoid the first opening of the container unless the frangible bridges of the safety seal placed on a circular portion of the cover are broken.
  • container cover comprising at least one safety seal device which is suitable for receptacles which are not necessarily cylindrical in shape, without resulting in decreased versatility with respect to known solutions.
  • a container cover is suitable for covering a receptacle cavity of an associable receptacle by resting on at least one lip of said receptacle to close and seal said receptacle cavity.
  • a container cover is associable with a variety of receptacles having predetermined features in terms of shape and size.
  • said cover comprises at least one safety seal device which is suitable for indicating the occurrence of the first opening of the container and is suitable for showing the occurrence of the tampering with the container.
  • said at least one safety seal device comprises at least one frangible element and at least one hinge element which are structurally connected so as to define a slice of said cover.
  • said at least one safety seal device comprises a hooking tooth which is suitable for projecting cantilevered from said cover towards at least one of said side walls of said receptacle when said cover is mounted on said receptacle, and is suitable for coupling as an undercut against a lip face of said lip facing opposite to said cover so as to snap fit said cover to said receptacle to close said receptacle cavity.
  • said frangible element has such a shape as to be more brittle with respect to said hooking tooth, so that said safety seal device indicates the occurrence of the first opening of the container by means of the breakage of said at least one frangible element.
  • said cover has a substantially square plan and comprises four safety seal devices placed on four vertexes of said substantially square.
  • said cover is suitable for closing and sealing a receptacle for degradable items, such as e.g. foodstuffs, such as e.g. ice-cream, bakery or deli items.
  • degradable items such as e.g. foodstuffs, such as e.g. ice-cream, bakery or deli items.
  • said cover is suitable for closing and sealing a receptacle for degradable items, such as the non-limiting example of mechanical components.
  • a container cover 1, or cover 1 which is suitable for closing a receptacle to form a container, comprises at least one safety seal device 10 suitable for indicating the occurrence of the first opening of the container and is suitable for showing the occurrence of the tampering with the container.
  • first opening of the container means the event, or operation, which causes the first (in chronological order) opening of the container and which is carried out by means of removing the container cover, when the safety seal device is still intact.
  • first closure of the container means the event, or operation, which causes the first (in chronological order) closure of the container and which is carried out by means of mounting said cover on an associable receptacle. Said first closure temporally precedes said first opening. According to one embodiment, said first closure is a step of production while said first opening is an operation carried out by the user of the container.
  • Said container comprises a receptacle 2 associable with said cover 1 and comprising side walls 7 for delimiting at least one receptacle cavity 9, said side walls comprising at least one lip 8 which projects opposite to said receptacle cavity 9.
  • said lip 8 surrounds the access hole to said receptacle cavity 9 and projects cantilevered with respect to said side walls 7 towards the outside of said receptacle 2.
  • Said cover 1 is suitable for covering said receptacle cavity 9 by resting on said at least one lip 8 to close and seal said receptacle cavity 9.
  • said cover 1 is suitable for closing and sealing said receptacle cavity 9.
  • said cover 1 comprises at least one outer edge wall 3, which defines with an edge thereof, perimeter 27 of said cover 1. According to one embodiment, said outer edge wall 3 extends surrounding the whole cover 1.
  • Said safety seal device 10 comprises at least one frangible element 11 and at least one hinge element 12 which are structurally connected so as to delimit a slice 13 of said cover 1.
  • said at least one frangible element 11 and said hinge element 12 are structurally connected to form a continuous path which connects two separate portions of said perimeter 27 of said cover 1.
  • said at least one frangible element 11 and said at least one hinge element 12 have substantially linear extension and are structurally connected to form a path.
  • said linear extension may be an at least partly curved path, or an at least partly straight path, or an at least partly broken line path, or at least partly straight line path.
  • said safety seal device 10 comprises two frangible elements 11 which extend at opposite ends of said hinge element 12.
  • said two frangible elements 11 are both placed on said outer edge wall 3.
  • said outer edge wall 3 comprises said at least two frangible elements 11.
  • Said at least one safety seal device 10 comprises at least one hooking tooth 14 which is suitable for projecting cantilevered from said cover 1 towards said lip 8 of said receptacle 2 when said cover 1 is mounted on said receptacle 2.
  • Said at least one hooking tooth 14 is suitable for coupling as an undercut against a lip face 15 of said lip 8 facing opposite to said cover 1, so as to snap fit said cover 1 to said receptacle 2 to close said receptacle cavity 9.
  • said at least one hooking tooth 14 substantially is unsuitable for flexural work.
  • the structure of said hooking tooth 14 makes it unsuitable for being elastically deformed with respect to slice 13 and said slice has such a structure so as to be elastically deformed.
  • said at least one hooking tooth 14 has a thickness such as to make it unsuitable for bending.
  • said slice 13 comprises at least one window 18 which is suitable for making said slice 13 elastically deformable so as to allow the snap fitting of said cover 1 to said receptacle 2.
  • said window 18 increases the flexibility of said slice 13 by removing a quantity of material which would limit the elastic bending and tensile deformation of said slice 13, and allows said slice 13 to be elastically deformed during the first closure of the container, thus avoiding said hooking tooth 14 from obstructing the first closure.
  • said slice 13 extends elastically during the first closure so as to allow said hooking tooth 14 to couple as an undercut against said lip wall 15 facing opposite to said cover 1.
  • a safety seal device 10 allows the snap fitting functions carried out by the hooking tooth 14 and the structural flexibility functions carried out by the flexible slice 13 not to be coupled.
  • the snap fitting and structural flexibility functions are made independent from each other since they are carried out by separate structural elements of the safety seal device 10. This gives the undercut coupling significant resistance and makes the cover 1 suitable for closing and possibly sealing the associable receptacle 2, also for closure operations of the container following the first closure.
  • said safety seal device 10 is suitable for closing said associable receptacle 2, while cover 1 comprises further means which are suitable for sealing said associable receptacle 2. According to one embodiment, said safety seal device 10 is suitable for closing and sealing said associable receptacle 2.
  • said slice 13 comprises flexible slice arms 30 surrounding said window 18.
  • said at least one hooking tooth 14 comprises at least one abutment surface 16 which is suitable for facing said lip face 15, and at least one introduction slide 17 which is inclined so as to slide on a portion of said at least one lip 8 and is suitable for causing the elastic deformation of said slice 13 to allow the first closure of the container, thus avoiding to cause the breakage of said at least one frangible element 11.
  • Such a hooking tooth 14 comprising said introduction slide 17 makes said hooking tooth 14 suitable for causing the orientation of the forces exchanged between cover 1 and receptacle 2 during the first closure of the container, and also during the course of the first opening of the container, and also when the cover is mounted snap fitted to the receptacle.
  • the thrust applied on cover 1 and directed towards receptacle 2 due to said introduction slide 17 at least partly results in a drawing of said at least one slice 13 so as to allow said abutment face 16 of said hooking tooth 14 to couple as an undercut against said lip face 15 of said receptacle 2.
  • said introduction slide 17 is tapered so as to favorably guide the mounting of said cover 1 onto an associable receptacle 2.
  • said at least one abutment surface 16 is substantially flat and substantially oriented parallel to said lip face 16 of a receptacle 2 which is associable with said cover 1.
  • said frangible element 11 is structurally identical to said hinge element 12 and the breakage of said frangible element 11 is exclusively caused by the positioning of said frangible element 11 in the body of said cover 1.
  • said frangible element 11 has such a shape as to be more brittle with respect to said hooking tooth 14, so that said safety seal device 10 indicates the occurrence of the first opening of the container by means of the breakage of said at least one frangible element 11.
  • said frangible element 11 has such a shape as to be more brittle with respect to said hooking tooth 14, so that said safety seal device 10 indicates the occurrence of the first opening of the container by means of the breakage of said at least one frangible element 11.
  • said slice 13 comprises a tab 19 which projects substantially cantilevered from said cover 10 to form a gripping element, to obtain the opening of said cover 1.
  • said tab 19 is lifted to obtain the first opening of said cover 1.
  • said tab 19 is suitable for uncoupling said hooking tooth 14 by tearing said at least one frangible element.
  • Such a tab 19 allows said at least one frangible element 11 to be torn by applying an incremental drawing force to said frangible element, which initially deforms at least a portion of said frangible element 11 by extending it, and then, once the breakage load of the frangible element 11 is exceeded, causes the tearing breakage thereof.
  • said frangible element 11 comprises a lead-in portion to tearing 29 which delimits a gap obtained in the cover perimeter 27. Thereby, the propagation is promoted of the tearing in the frangible element 11.
  • said frangible element 11 comprises at least one connection bridge which thickness is less than the thickness of the hooking tooth 14. Thereby, said at least one frangible element 11 is made more brittle than said hooking tooth 14.
  • said hinge element 12 is unsuitable for breaking so as to allow said slice 13 to remain in one piece with said cover 1 even when said frangible element 11 has been broken.
  • said frangible element 11 is biased and said hinge element 12 is flexurally biased.
  • said hinge element 12 is more resistant than said frangible element 11.
  • said hinge element 12 has a greater thickness than said frangible element 11. Thereby, said hinge element is more resistant than said frangible element 11.
  • said hinge element 12 has a substantially rectilinear extension and said at least one slice 13, after the first opening of the container, is suitable for rotating around a hinge axis comprised in, or substantially coinciding with said hinge element 12.
  • said tab 19 allows said slice 13 to be folded over said hinge element 12, the same way as a dog-ear of a notebook.
  • said hinge element 12 has a substantially rectilinear extension so that said slice 13 has a substantially triangular plan.
  • said tab 19 is also suitable for carrying out opening operations of the cover following the first opening.
  • said tab 19 is shaped so that by lifting said tab 19, the rotation is caused of said slice 13 around said hinge axis.
  • said tab 19 is shaped so as to increase the lever arm of said slice 13 so that by lifting said tab 19, the tearing is caused of said frangible element 11.
  • said tab 19 is shaped so as to allow the elastic deformation of said slice 13 to carry out the first closure of the container, thus avoiding the deformation of said hooking tooth 14.
  • said outer edge wall 3 is a strip of material which is integral with said cover 1, which surrounds said cover.
  • said outer edge wall 3 comprises at least one first side portion 4 and at least one second side portion 5 having substantially rectilinear extension, in which said first side portion 4 is not parallel to said second side portion 5, so that said first side portion 4 and said second side portion 5, or extensions thereof, define at least one corner portion 6 of said cover 1.
  • said corner portion 6 comprises said at least one safety seal device 10.
