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.
  • a can lid with a resealable opening in which an opening is made in the metallic can lid and the edge of this opening is flanged in order to create an anchoring option for a prefabricated plastic closure part.
  • the plastic closure part comprises a base part to be connected to the flanged edge of the can opening, in which an opening closed by a flat plug is formed.
  • the flat plug is connected to the opening edge via a plastic tear seam, so that the flat plug connected to a tear tab can be detached from the plastic base part by pulling on the tear 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.
  • Reclosable can lids are also available, for example US2004/159 665 A1 , DE 10 2010 013 531 A1 , the DE 10 2015 112 428 A1 and the EP 2 354 022 B1 described.
  • a can lid according to the preamble of claim 1 is from US 2018/016058 A1 known.
  • the object of the invention is to provide a resealable can lid that is particularly inexpensive to produce and yet, on the one hand, is easy to operate and, on the other hand, has good sealing properties.
  • a micro-gap ensures that the can lid is particularly easy to open, but a weakening line is also generally suitable. Effective closure and re-closure can be achieved using the sealing and locking ribs as well as the associated receiving grooves. It is particularly advantageous here that the sealing frame is cohesively connected to the fixed lid surface and the closing unit to the pivotable metallic lid area.
  • the sealing and locking ribs with the receiving grooves form at least two, preferably three sealing edges, the sealing edges being designed such 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. In this way, 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 is at a greater distance from the cover surface than the other or the other two sealing edges. This causes the innermost sealing edge to release after the other two sealing edges, so that the aforementioned venting is achieved.
  • At least the radially innermost sealing edge runs in a plane which is inclined relative to the plane of the cover area located within the micro-gap or the line of weakness, the two planes being the greatest distance from one another on the side facing away from the pivot bearing.
  • 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 get caught together when the can lid bulges. This can ensure 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 outward-pointing hook which interacts with a corresponding inward-pointing locking projection of a receptacle of the closing unit.
  • the tear-open element has an opening into which an extension of the closure unit engages, the extension being connected to the tear-open element so firmly, in particular in a materially bonded manner, that the extension is torn off from the closure unit when the tear-open element is swung up.
  • This design creates a tamper-evident closure, i.e. 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 as soon as the tear-open part is lifted, so that any manipulation of the can lid can be prevented.
  • the can lid 1 shown in the figures is made of metal, in particular aluminum, and has a resealable opening.
  • a lid area 3 that can be swung up is provided in the lid.
  • the pivotable lid area 3 is separated from the fixed lid area 2 by a circumferential micro-gap 4 or a weakening line (see in particular Fig. 6 ).
  • a sealing frame 5 made of plastic material surrounding the opening area is connected to the fixed lid surface 2, in particular by a so-called hot-melt process using an adhesion promoter in order to ensure a firm connection to the aluminum of the lid.
  • a closing unit 6 is also connected to the pivotable metallic lid area 3, which is also made of plastic and is pivotally attached to the fixed lid surface 2 via a pivot bearing 7. The pivot bearing 7 and the closing unit 6 are in turn connected to the fixed lid surface 2 or the pivotable lid area 3, in particular via a hot-melt connection using an adhesion promoter.
  • the closing unit On the side diametrically opposite the pivot bearing 7, the closing unit is connected to a pivotable tear member 8, which is arranged parallel to the top side of the lid 9 when not pivoted up.
  • the tear-open element 8 is ring-shaped in a known manner and can be pivoted up around a pivot bearing 11 relative to the cover surface by engaging a finger in an engagement end 10.
  • 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. This creates three sealing edges 18, 19, 20, through which the opening area of the can lid is sealed. Even when using a micro-gap 4 between the swivel-up Lid area 3 and the fixed lid area 2 thereby ensure that the can lid is tight.
  • 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 just loosened 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 it is completely opened.
  • the radially innermost sealing edge 18 runs in a plane I which is inclined relative 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 lid area 3 is swung up when the two outer sealing edges 19, 20 have just been released. 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 outward-pointing hook 21, which interacts with a corresponding inward-pointing locking projection 22 of the associated receptacle 15 of the closing unit 6. This ensures that the sealing and locking rib 12 becomes increasingly entangled 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 member 8 has an opening 23 into which an extension 24 of the closing unit 6 engages.
  • the extension 24 is so firm, in particular cohesively, with the tear-open member 8 connected that the extension 24 is torn off from the closing unit 6 when the tearing member 8 is swiveled up.
  • Such a firm connection can be achieved, for example, by melting the extension 24 after the injection molding of this plastic part in such a way that it firmly connects to the part of the tear-open member 8 that forms the opening 23. This can be achieved, for example, with a type 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 ensures that even a slight lifting of the tearing 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 a ring shape and extend beyond the micro-gap 4 or the weakening line by only a few tenths of a millimeter, in particular 3 to 4 tenths of a millimeter, on both sides.
  • Another possibility is to use a disk-shaped sealing film that extends radially outward beyond the micro-gap 4 or the weakening line by a few tenths of a millimeter, for example 3 to 4 tenths of a millimeter.
  • the sealing film can be designed as a largely flat disk. Both the annular and the disc-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 be made with a material that is particularly suitable for foodstuffs Be provided with a layer of paint to prevent the goods in the can from coming into contact with the metallic lid material.
  • the closing unit 6 which is cohesively connected to the fixed lid area 2, engages over the micro-gap 4. In this way, a tightness of the can lid can be ensured even without a sealing film on the inside of the lid.
