Definitions

  • the invention relates to a can lid, in particular for beverage cans, with a metallic lid surface in which an opening is formed which is delimited by a closed edge of the lid surface and which is closed by a closure piece of the metallic lid surface, wherein the closure piece is separated from the surrounding lid surface by a micro-gap which extends at least in sections along the edge of the lid surface, wherein a first end region of the closure piece is connected to the surrounding lid surface via a pivot bearing, and with a tear-open member which engages a second end region of the closure piece opposite the pivot bearing, so that by pulling on the tear-open member, the closure piece can be pivoted out of the plane defined by the opening.
  • Can lids of this type are used extensively in the manufacture of beverage cans, food cans and the like. They are easy and inexpensive to manufacture, enable space-saving stacking of similar cans and can be easily opened and closed again if necessary by manually moving the closure piece. Due to the micro-gap, no metal particles enter the interior of the can when the can is opened, which could be hazardous to health.
  • the invention provides that the micro-gap between the first end region and the second end region is interrupted by at least one retaining web, via which the closure piece and the surrounding lid surface are connected to one another in a materially bonded manner.
  • a particular advantage is the simple construction of a can lid according to the invention, because it is sufficient not to make the existing micro-gap completely circumferential, but to provide a recess to form the retaining web. It is therefore not necessary to provide a separate additional retaining device.
  • a further advantageous effect of the invention is that the retaining bar increases the stability of the lid closure. It has been shown that Due to the metal retaining bar, even when the internal pressure in the can is greatly increased and/or at high temperatures, there is no risk of leaks or the closure piece even breaking off. High temperatures and the associated high internal pressure do not only occur when cans containing carbonated drinks are exposed to sunlight, but also during pasteurization, which is required for many applications. Any sealing film intended to cover the micro-gap is protected from overload by the retaining bar.
  • the retaining bar is also advantageous in that it ensures that the closure piece is reliably held in the opening during production.
  • the at least one retaining web has a width of 0.1 mm to 6 mm, preferably 1.5 mm to 4 mm. It has been shown that with such a web width, on the one hand, a sufficiently strong holding effect is ensured for a ventilation effect, but on the other hand, the retaining web is sufficiently easy to break in order to avoid hindering the opening process.
  • the width of the retaining web can be measured along the edge delimiting the opening or along the course of the micro-gap.
  • the at least one retaining web can have a notch.
  • the notch ensures that the retaining web tears in a defined manner when the closure piece is first pivoted upwards, namely along the notch. This prevents unwanted tearing of the closure piece or the surrounding lid surface.
  • the notch can extend along the edge of the lid surface and/or the micro-gap. The shape and depth of the notch can be adapted to produce a desired tearing force.
  • the notch preferably has a depth of at least 0.03 mm and/or at least a quarter of the thickness of the metallic lid surface.
  • the micro-gap between the first end region and the second end region is interrupted by a web arrangement of at least two retaining webs, via which the closure piece and the surrounding lid surface are connected to one another in a materially bonded manner.
  • This ensures that the closure piece is evenly fixed in the opening.
  • the web arrangement can be designed in such a way that a relatively small initial opening is formed during the opening process. The smaller the initial opening is, the more controlled and gentle the excess pressure can escape.
  • the web arrangement can comprise holding webs arranged on both sides of the second end region. This means that a separation of the micro-gap is resisted on both sides of the point of action of the tearing element, so that the holding effect is uniform.
  • the web arrangement comprises at least one pair of holding webs arranged opposite one another with respect to a central region of the closure piece. This ensures symmetrical resistance to the opening movement.
  • the web arrangement can comprise at least four and at most eight, preferably six, retaining webs distributed along the edge of the lid surface. This results in a particularly stable hold of the closure piece in the opening and counteracts overloading of a coating or film covering the micro-gap.
  • the retaining webs of the web arrangement can be designed identically to ensure a particularly simple construction.
  • a further embodiment of the invention provides that the micro gap is a punching gap and the at least one retaining web is formed by a punching recess This enables particularly simple and cost-effective production.
  • An embossing device such as an embossing stamp can be arranged in the punching recess, which is designed to produce a notch, in particular as described above, in the relevant holding web.
  • the micro gap has a maximum width of 0.01 mm. This has proven to be particularly advantageous in practice.
  • the closure piece can also be held in place by clamping in the surrounding lid surface.
  • a coating made of a plastic material can be applied to a flat side of the metal lid surface, covering the micro-gap.
  • the tightness of the can lid is ensured by a coating covering the micro-gap despite the lack of a continuous metal connection between the closure piece and the surrounding lid surface.
  • the coating made of plastic material tears in the area of the micro-gap, so that the opening is subsequently free.
  • the coating is applied to an inner side of the metallic lid surface.
  • the coating is therefore preferably located on the side of the lid facing the inside of the can. This is generally the underside of the metallic lid surface.
  • the coating can be applied to the entire flat side of the metal cover surface. This is advantageous in terms of production technology and ensures a particularly high sealing effect.
  • the coating can be designed as a film and/or applied firmly to the metal cover surface, for example sealed.
  • the plastic material can be food-grade polypropylene.
  • the coating has a weakening, in particular a material thickness that is reduced in some areas, which is arranged at a distance from the micro-gap.
  • the weakening can be created during a sealing process by means of which the coating is applied.
  • a notch or at least a partial notch such as a perforation could be provided as a weakening.
  • the weakening reduces the amount of force required to open the can. Due to the distance between the weakening and the micro-gap, a high level of tightness is ensured.
  • the tear-open element can be a handle, pull and/or lever element, in particular made of plastic material.
  • a user can actuate the handle, pull and/or lever element in order to pivot the closure piece upwards about the pivot bearing axis defined by the pivot bearing.
  • a two-armed lever element made of a plastic material can be provided, which is firmly connected to the metal lid surface.
  • the handle, pull and/or lever element has an annular grip section such as a ring tab.
  • a ring tab is particularly advantageous because it can be easily grasped and enables the respective can to be opened using a convenient pulling movement.
  • a further embodiment of the invention provides that a sealing frame made of plastic material enclosing the opening is connected to the surrounding lid surface and a closing unit made of plastic material carrying the closure piece is pivotally attached to the surrounding lid surface, wherein the sealing frame and the closing unit can be releasably connected to one another in a fluid-tight manner via sealing and locking ribs and associated receiving grooves.
  • Such a can lid has a resealable opening.
  • the sealing and locking ribs as well as the receiving grooves are designed in such a way that complete reclosure by the snap-lock connection can be felt and possibly perceived acoustically.
  • the closure piece of a resealable can lid cannot be deformed sufficiently to provide venting via the deformation.
  • the invention is therefore particularly suitable, but not exclusively, for resealable can lids.
  • the invention also relates to a method for producing a can lid, in particular a can lid for beverage cans, preferably a can lid as described above, wherein a metal element which is at least partially flat is provided and wherein a closure piece is punched out of the metal element and reinserted into the opening formed by the punching process.
  • the punching is carried out by means of a punching die which has a cutting edge with at least one recess. This enables a particularly simple creation of a retaining web in the form of a material connection between the closure piece and the surrounding lid surface.
  • the invention also relates to a can lid, in particular for beverage cans, with a metallic lid surface in which an opening is formed which is delimited by a closed edge of the lid surface and which is closed by a closure piece of the metallic lid surface, wherein the closure piece is separated from the surrounding lid surface by a micro-gap extending at least in sections along the edge of the lid surface, in particular a can lid as described above.
  • an arrangement of ventilation notches is introduced into the metallic cover surface, which are connected to the micro-gap.
  • the venting notches When a sealing film is applied to the metal cover surface, the venting notches ensure ventilation via the micro gap and thus counteract unwanted bubble formation between the sealing film and the metal cover surface.
  • the venting notches can be embossed into the metal cover surface.
  • the venting notches have a V-shaped cross section and/or a depth of 0.005 mm to 0.2 mm, preferably 0.03 mm to 0.1 mm.
  • the arrangement of ventilation notches is introduced into an inner side of the metallic cover surface, in particular wherein a coating made of a plastic material is applied to the inner side of the metallic cover surface so as to cover the micro-gap and at least partially cover the arrangement of ventilation notches.
  • venting notches define a radial pattern and/or that each of the venting notches extends at least from the micro-gap to an edge region of the metallic cover surface. This enables effective venting across the entire film surface or cover surface.
  • the Fig.1 shows a can lid 11 intended in particular for a beverage can, in whose metallic lid surface 13 a reclosable opening system 15 is integrated.
  • the can lid 11 can be connected to an associated container (not shown) via a flanged edge 12.
  • An opening is provided in the metallic lid surface 13, which in the Fig.1 shown delivery state of the can lid 11 is closed by a section of the metallic lid surface 13 in the form of a closure piece 19.
  • the closure piece 19 is separated from the surrounding cover surface 23 by a micro-gap 21.
  • the outer edge 25 of the closure piece 19 and the inner edge 27 of the surrounding cover surface 23 adjoin one another.
  • the metallic cover surface 13 is preferably formed from a sheet metal layer made of aluminum or tinplate.
  • a coating made of plastic material covering the micro gap 21 is applied to an inner flat side of the metallic cover surface 13, which in Fig.1 and 2 however, is not visible.
  • an adhesive layer which is also not visible in the figures, can be provided.
  • the coating is preferably applied over the entire surface of the inner flat side of the metallic cover surface 13. In certain applications, however, it may also be sufficient to provide a coating only in the vicinity of the micro-gap 21.
  • the coating can be a plastic film, for example made of polypropylene.
  • a notch is formed in the coating, which extends along the micro-gap 21 at a predetermined distance from the latter.
  • the can lid 11 can be opened by pressing the can lid 11 against the paper plane (the paper plane). Since there is no material connection between the closure piece 19 and the surrounding lid surface 23 in the area of the micro gap 21, no significant metal separation needs to take place when a can provided with the can lid 11 according to the invention is opened for the first time, so that the otherwise unavoidable formation of metallic microparticles is reduced or completely prevented. This avoidance of the formation of microparticles during the opening process, in particular microparticles made of aluminum, is important from a health perspective, because such microparticles inevitably also get into the product contained in the respective can and thus also into the human body.
  • the coating reliably seals the micro gap 21.
  • the notch which can have a uniform depth or locally different depths, ensures that only one comparatively little force is required.
  • the distance between the micro gap 21 and the notch which is preferably about 0.2 to 0.5 millimeters, improves the sealing effect.
  • the resealable opening system 15 ( Fig.1 ) comprises a cover enclosing the opening, in plan view according to Fig.1 not visible sealing frame made of plastic material, which is firmly connected to the surrounding lid surface 23. Furthermore, a closing unit 40 made of plastic material is provided which carries the closure piece 19 and is pivotably attached to the surrounding lid surface 23.
  • a locking device which is formed by sealing and locking ribs and associated receiving grooves, a detachable fluid-tight connection between the sealing frame and the closing unit 40 is made possible. Accordingly, the can lid 11 is reclosable.
  • a ring-shaped tear-open member 47 preferably also made of plastic, is connected to the closing unit 40 or molded directly onto it and is accordingly attached to the closure piece 19.
  • a pivot bearing 48 Diametrically opposite the tear-open member 47, a pivot bearing 48 ( Fig.1 ) which is firmly connected to the surrounding cover surface 23.
  • a first end region 61 of the closure piece 19 is connected to the surrounding cover surface 23 via the pivot bearing 48, while the tear-open member 47 engages a second end region 62 of the closure piece 19 opposite the pivot bearing 48.
  • the micro gap 21 is defined by two retaining webs 65 ( Fig.2 ) through which the closure piece 19 and the surrounding cover surface 23 are firmly connected to one another are connected.
  • the two retaining webs 65 form a web arrangement 70.
  • the two retaining webs 65 are arranged opposite one another with respect to a central region 66 of the closure piece 19.
  • the width of the identically designed retaining webs 65 is preferably in a range from 0.5 mm to 6 mm and is, for example, at least approximately 3 mm. Depending on the application, more than two retaining webs 65 can also be provided.
  • a detailed view of one of the retaining webs 65 is shown in Fig.3 , whereby the micro-gap 21 is shown exaggeratedly wide for clarity.
  • the retaining webs 65 preferably have respective notches 75 in order to avoid undefined tearing of the metallic cover material.
  • the retaining webs 65 Due to the retaining webs 65, at the beginning of the pivoting process only a relatively small opening is created in the lid surface 13, which extends from the second end region 62 to the area of the retaining webs 65.
  • the retaining webs 65 prevent any further opening, at least for a short time.
  • the relatively small opening in the vicinity of the second end region 62 ensures that the can is ventilated.
  • the retaining webs 65 tear, particularly because they are relatively narrow. After the retaining webs 65 tear, the closure piece 19 can be pivoted completely upwards to expose the entire opening. Due to the gradual opening caused by the retaining webs 65 and the associated venting effect, there is no significant splashing, banging or foaming.
  • the contents of the can can be removed through the opening created.
  • the closing unit 40 with the closure piece 19 is swung back again, the locking connection between the closing unit 40 and the sealing frame is restored so that the opening is tightly closed again despite the coating being torn.
  • the opening and closing can be repeated as often as desired.
  • a web arrangement 70' with a total of six holding webs 65 is provided, which are distributed along the edge 27 of the metallic lid surface 13.
  • an arrangement of three holding webs 65 is located on each side of a line 72 running through the first end region 61 and the second end region 62. This enables finely graduated venting on the one hand and ensures a particularly stable hold of the closure piece 19 in the intended position before the closure is first opened on the other. It is understood that the number, distribution and width of the holding webs 65 can vary depending on the respective application.
  • Fig.5 shows a can lid 13 according to the invention in a simplified form from below.
  • An arrangement of venting notches 80 is introduced into the underside, i.e. the inside, of the metallic lid surface 13.
  • each of the particularly straight venting notches 80 extends from an edge region 87 of the metallic lid surface 13 to the micro gap 21. They could also extend slightly beyond the edge region 27.
  • the course of the venting notches 80 is radial.
  • the venting notches 80 define a radial pattern, i.e. the radially running venting notches 80 are distributed over the circumference of the circular metallic lid surface 13.
  • the venting notches 80 are preferably embossed into the metallic lid surface 13 by means of an embossing tool, for example with an embossing depth of 0.07 mm.
  • the micro gap 21 and the arrangement of venting notches 80 are of a Fig.5 invisible plastic sealing film that is applied to the inside of the metal cover surface 13.
  • the venting notches 80 cause the gap between the metal cover surface and the sealing film to be vented via the micro gap 21, particularly when the sealing film is applied.
  • the existing micro gap 21 is therefore used for venting. In this way, the formation of bubbles and the like is prevented, due to the radial pattern across the entire metal cover surface 13.
  • the effect of the retaining webs 65 is independent of the presence of the resealable opening system 15. Therefore, the provision of one or more retaining webs 65 as described is also advantageous for non-resealable can lids without a sealing frame and closing unit, i.e. for standard can lids.
