Definitions

  • the present invention relates to a metallic can lid with a resealable opening, in particular for beverage cans and for containers for storing food and other liquid, pasty, powdery and / or solid products.
  • the plastic closure part comprises a base part which is to be connected to the flanged edge of the can opening and in which an opening closed by a flat stopper is formed.
  • the flat stopper is connected to the opening edge via a plastic tear seam, so that the flat stopper connected to a pull tab can be detached from the plastic base part by pulling over the pull tab and pivoted into an opening point.
  • the opening can be temporarily closed again by pressing in the flat plug, which is preferably conical on its underside.
  • Resealable can lids are also for example in the DE 10 2010 013 531 A1 , the DE 10 2015 112 428 A1 and the EP 2 354 022 B1 described.
  • the object of the invention is to provide a resealable can lid which is particularly inexpensive to manufacture and yet on the one hand easy to operate and on the other hand has good sealing properties.
  • a micro gap ensures that the can lid can be opened particularly easily, but a line of weakness is also generally suitable.
  • An effective closure and reclosure can be achieved via the sealing and locking ribs and the associated receiving grooves. It is particularly advantageous here that the sealing frame is firmly connected to the fixed cover surface and the closing unit to the metal cover area that can be pivoted up.
  • the sealing and locking ribs with the receiving grooves form at least two, preferably three sealing edges, the sealing edges being designed so that when the can lid is opened, the radially innermost sealing edge still seals when the radially outer or both radially outer sealing edges are just released.
  • so-called venting of a can closed with the can lid can be achieved, that is, a slow pressure reduction before the can lid is completely opened.
  • the radially innermost sealing edge has a greater distance from the cover surface than the other or the two other sealing edges. As a result, the innermost sealing edge detaches after the other sealing edge or two, so that said venting is achieved.
  • At least the radially innermost sealing edge runs in a plane that is opposite to the plane of the is inclined inside the microgap or the weakening line lid area, the two planes on the side facing away from the pivot bearing have the greatest distance from each other.
  • the sealing and locking ribs on the one hand and the receiving grooves on the other hand are designed in such a way that they increasingly interlock with one another when the can lid bulges. This ensures that the can lid remains closed even when the internal pressure in the can increases.
  • a locking rib provided on the sealing frame has an outwardly pointing hook which cooperates with a correspondingly inwardly pointing locking projection of a receptacle of the closing unit.
  • the tear-open member has an opening in which an extension of the locking unit engages, the extension being firmly, in particular cohesively, connected to the tear-open member that the extension is swiveled up of the ripping member is torn off from the sealing unit.
  • This configuration creates a tamper-evident closure, that is to say a closure whose opening is irreversibly recognizable.
  • the opening and the extension are provided in the area of the pivot bearing of the tear-open part. This ensures that the extension is torn off takes place when the tear-open part is raised, so that any manipulation of the can lid can be prevented.
  • the can lid 1 shown in the figures consists of metal, in particular aluminum, and has a resealable opening.
  • a lid area 3 that can be pivoted up is provided in the lid in addition to a fixed lid surface 2.
  • the pivotable lid area 3 is separated from the fixed lid area 2 by a circumferential microgap 4 or a line of weakness (see in particular Fig. 6 ).
  • a sealing frame 5 made of plastic material surrounding the opening area is connected to the fixed cover surface 2, in particular by a so-called hot-melt process using an adhesion promoter, in order to ensure a firm connection with the aluminum of the cover.
  • the closing unit On the side diametrically opposite the pivot bearing 7, the closing unit is connected to a pivotable tear-open member 8 which, when not pivoted up, is arranged parallel to the top 9 of the lid.
  • the tear-open member 8 is designed in a known manner in the shape of a ring and, by engaging a finger in an engaging end 10, can be pivoted upward about a pivot bearing 11 relative to the cover surface.
  • the sealing frame 5 and the closing unit 6 work together in a sealing manner via sealing and locking ribs 12, 13, 14 on the sealing frame 5 and associated receiving grooves 15, 16, 17 on the closing unit 6. As a result, three sealing edges 18, 19, 20 are formed, through which the opening area of the can lid is sealed. Even when using a micro gap 4 between the pivotable Lid area 3 and the fixed lid area 2 thereby ensure that the can lid is sealed.
  • the radially innermost sealing edge 18 is further away from the lid surface than the other two sealing edges 19 and 20.
  • the innermost sealing edge 18 therefore still seals when the two outer sealing edges 19 and 20 are already released when the can lid is opened. In this way, so-called venting of the inside of the can can take place, i.e. a slow pressure reduction before complete opening.
  • the radially innermost sealing edge 18 runs in a plane I, which is inclined with respect to the cover plane II.
  • the inclination is, for example, 1 to 2 °, in particular 1.5 °. This ensures that the innermost sealing edge 18 still seals over its entire circumference when the cover region 3 is pivoted up, when the two outer sealing edges 19, 20 have just loosened. When venting the inside of the can, this can prevent liquid from escaping from the inside of the can.
  • the radially outermost sealing and locking rib 12 provided on the sealing frame 5 has an outwardly pointing hook 21 which interacts with a correspondingly inwardly pointing locking projection 22 of the associated receptacle 15 of the closing unit 6.
  • the sealing and locking rib 12 increasingly interlocks with the receptacle 15 or its locking projection when the can lid bulges, for example due to increasing internal pressure in the can.
  • the tear-open member 8 has an opening 23 into which an extension 24 of the closing unit 6 engages.
  • the extension 24 is so firmly, in particular cohesively, with the tear-open element 8 connected that the extension 24 is torn off from the closing unit 6 when the ripping member 8 is pivoted upward.
  • Such a fixed connection can be achieved, for example, in that the extension 24 is melted after the injection molding of this plastic part in such a way that it is firmly connected to the part of the tear-open element 8 that forms the opening 23.
  • This can be achieved, for example, by a kind of soldering iron.
  • the opening 23 and the extension 24 are provided in the area of the pivot bearing 11 of the tear-open member 8. This means that even a slight lifting of the tear-open member 8 is sufficient to tear off the extension 24.
  • the inside of the can lid is laminated with a plastic film 25 which covers the entire inside of the lid.
  • the plastic film can also be designed in the shape of a ring and only extend by a few tenths of a millimeter, in particular 3 to 4 tenths of a millimeter, on both sides beyond the microgap 4 or the line of weakness.
  • Another possibility is to use a disk-shaped sealing film which extends by a few tenths of a millimeter, for example 3 to 4 tenths of a millimeter, radially outward beyond the microgap 4 or the line of weakness.
  • the sealing film can be designed as a largely flat disk. Both the ring-shaped and the disk-shaped sealing film are preferably designed as a stamped part.
  • the inside of the lid can, in contrast to the exemplary embodiment, also be at least largely free of laminations and the like.
  • the inside of the lid can, however, be equipped with an in particular food grade Be provided with a layer of lacquer to prevent the goods in the can from coming into contact with the metallic lid material.
  • the sealing unit 6 which is firmly connected to the fixed lid area 2, overlaps the microgap 4. In this way, a tightness of the can lid can be ensured even without a sealing film on the inside of the lid.
