Definitions

  • the invention relates to a lid made from sheet metal for closing container bodies, the content of which is under increased internal pressure, as is known from cans for drinks containing carbonic acid.
  • a limited region is originally closed by sheet metal and is then separated off by the action of a lever flap (tab) at a weakened line and pressed into the closed container. If one would like to design the can, and thus expressly the lid, to be reclosable, both solutions mentioned are not applicable.
  • the can may experience as few as possible modifying interventions during closing, in particular in the region of the sheet metal lid, in order to make it easier for the filler to get involved with a kind or a new type of can lid.
  • the principle of recloseability must thus be different without a tab (mostly SOT) being arranged on the lid panel.
  • a tab mostly SOT
  • additional free space is available which was hitherto occupied by the tab. This additional space is situated directly in the lid plane (slightly thereabove).
  • a sheet metal lid for closing a drinks can to facilitate assembly of an initially separate reclosing device and to facilitate its assembly on the sheet metal lid.
  • the sheet metal lid should also be designed so that it retains its pressure stability, that it does not lose the stackability and lies as close as possible to a standard shell in its at least external edge design in order to keep changes on a filling line as low as possible.
  • the recloseability of the container should however be facilitated by the lid, since the ironed (by DWI) one-part can body cannot contribute anything to this solution (recloseability) due to its original properties.
  • This object is achieved by claim 1 , claim 2 or claim 32 or 33 .
  • This lid is manufactured by a method (claim 31 ).
  • the invention adds to a solution in which an additional part (a reclosing device) is inserted in a “large opening” in the lid panel.
  • This additional part is not to be an object of is this description and be claimed, but only the sheet metal lid which as such brings with it the suitability, property and precondition of being combined with such a reclosing device in order to then be mounted and rebated on a filled body as a closure lid by the filler.
  • the large-dimension opening in the panel should be understood so that it provides a significantly larger opening than is the case for the regions which can be broken described in the introduction (claim 1 , claim 26 ). They have only relatively small dimensions in order to be able on the whole to keep the stability of the panel.
  • LOE closure lids are known (Large opening end), which provide an enlarged opening particularly for Gulp-drinks, which is orientated transversely and designed to be reniform, nevertheless not circular due to the necessity which continues to exist of attaching a tab to the lid sheet metal externally (via a rivet), and also this reniform shape lies only on one side of the axial centre plane of the lid, see WO 97/30902 (ANCC), there FIG. 9 .
  • the opening surface area becomes large.
  • a perforation is preferably introduced into the lid, the opening dimension of which goes beyond the lid centre (claim 2 ).
  • the large-dimension perforation is not closed by a sheet metal section and also cannot be broken open via a scored or weakened line, but remains open in order to be closed later by the reclosing device which has adapted geometry. It permits the opening and closing of the flow path in the opened region (the perforation) so that here a “large-dimension opening” will be discussed further on, which is free for the flow of the drink, controlled by the reclosing device, but which is not to be illustrated here, see for this in detail PCT/NL2004/00024, filed on 13 Jan. 2004 (WO-A 2005/068312).
  • the sheet metal lid as such is now as before a finally shaped sheet metal lid originating from a manufacturing method (claim 31 ). It is more than a shell (the crude form), it is ready to be combined with the reclosure in order then in this combination to replace a conventional SOT closure lid which is normal today by a scored line and to close in reclosable manner the bodies closed by it, which are likewise not illustrated here, because they are available according to standard.
  • An enclosing strip which is offset in one plane, is provided around the large-dimension opening. It serves for stabilisation (claim 1 ).
  • the stiffening plateau preferably extends not further than partly peripherally and in radial direction, wherein it is orientated to be flat, designed in particular to be part moon-shaped or arc segment-shaped (claim 3 ). It may also be described so that it has a bulge section with greater radial dimension and two arm sections which extend peripherally (claim 11 ). The plateau thus extends in a peripheral angle of more than 180° (claim 12 ).
  • the central offsetting may be in the range between 5% and 25% of the diameter of the lid panel (in each case in the non-perforated state) depending on the dimensions of the main opening designed to be large and intended in most cases to be circular (claim 24 , 21 ). A range between 10% and 15% is preferred, relative to the said diameter of the panel (lid panel) within the peripheral groove.
  • This offsetting towards one side makes it possible to attach the additional stiffening on the other side due to the stiffening plateau in part moon-shaped or arc segment-shaped design (in short ‘half-moon-like’). It includes at least 90°, preferably approximately 180° of the opening and—relative to the lid panel—is designed to be encompassing more than 180° (claim 12 ). Due to the central offsetting, space is provided between the one edge of the opening and the peripheral groove to arrange this stiffening.
  • the opening is possible to start from more than 30% of the surface of the as yet non-perforated lid panel. This dimension relates to the surface area which is the square of the radius. If the size of the opening is related to diameter, the diameter of the opening (for substantially circular design) is greater than 50% of the diameter of the panel, the same also applies to the dimensions of the radii. A range between 55% and 65% is preferred (claim 5 ).
  • the opening is at least essentially round (claim 28 ) or at least approximately oval. It has a free inner edge (claim 36 ).
  • stiffening plateau By attaching the stiffening plateau partly peripherally to the opening, which is enclosed by the at least one peripheral strip, further partly peripheral strip geometry is possible, which is designated as a “further intermediate strip” (claim 15 ). It is situated between the outer edge of the stiffening plateau and the peripheral groove.
  • the further intermediate strip and the peripheral strip preferably have on their peripheral extension, a constant width (claim 16 ). Due to the structures extending peripherally and arranged differently, it is possible to provide changing heights of these structures, which now refers to the axial direction of the geometries previously mainly described in radial direction (claim 18 , 19 ).
  • an up-and-down may be formed, which due to changing height levels ensures that stiffening occurs which in spite of the large-dimension perforation (opening) can extend to the entire lid panel.
  • a step is thus produced between in each case two adjacent areas.
  • the step may have a piece running diagonally at least in sections, which leads into the particular next structure via particular radii (claim 20 ).
  • a datum plane may be defined as a reference (claim 4 ), which is placed on the plane of the perforation, that is, is placed in the plane of the opening.
  • Other geometries may be defined in the other height positions relative to this datum plane (claim 4 , claim 33 ).
  • the lid panel in spite of the destabilising “large opening”, has high pressure stability and in addition surprisingly controlled ‘buckling’, which corresponds to bulging of the lid at excessive internal pressure. Up to normal pressure and several times normal pressure, the lid however remains stable so that a safe sealing on the first peripheral strip may be achieved by the reclosing device (claim 22 ). It lies reliably at the same height position (at the same level along its entire periphery), to ensure a sealing function with respect to a sealing lip of the reclosing device. In its closing and sealing position the lip presses onto the peripheral strip.
  • the loss of strength may be reliably compensated.
  • the combination of all stiffening geometries, in particular the features pointed out according to claim 1 , 2 also achieve controlled ‘buckling’ in the sense of head space enlargement by increased internal pressure in the closed can. All requirements of the lid, the pressure stability, the considerable dependence on standard closures, the stackability and the possibility of facilitating reclosure, indicated in the introduction, are achieved.
  • the further edge strip may lie at a different height position (claim 7 ) than the first peripheral strip, preferable deeper (claim 8 ).
  • the opening for the said device may contain two opposing flat sections to improve assembly (claim 10 ).
  • the flat sections extend radially inwards (claim 10 ).
  • the plateau height may preferably be placed above the datum plane (claim 13 , 4 ). If the plateau is defined radially inwards and radially outwards by the two peripheral strips (intermediate strip and enclosing strip), different height levels of these three regions achieve improved stabilisation (claim 14 , 18 ). Enclosing strip and further intermediate strip (claim 15 ) may preferably be placed at the same height (claim 18 ).
  • Leading-in of the said further intermediate strip which does not extend fully peripherally, but only partly peripherally, just like the stiffening plateau, takes place at the arm ends of the stiffening plateau (claim 17 ).
  • a leading-in surface which is designed to be V-shaped or Y-shaped, is formed here.
  • the surface of the or part moon-shaped stiffening (claim 11 ) preferably has no additional beads on its flat extension (claim 23 ).
  • the modified shell that is the finished product, which is prepared to receive the reclosing device, has a constant opening, which is also called perforation, but is not covered by sheet metal (claim 21 ). It has no scored or weakened lines (claim 4 c). Further, no tab (rip-open flap) is attached to the sheet metal (claim 4 a).
  • the staggered change in height levels occurs from radially inward to radially outward, beginning with the inner edge strip (around the large opening) to the first enclosing strip, to the stiffening plateau, to the further intermediate strip and finally via the peripheral groove to the folding or mounting edge. Between the stiffening regions which extend peripherally over at least 90° preferably diagonal steps are arranged.
  • FIG. 1 is a plan view of a lid as one of several first examples.
  • FIG. 2 is an axial section A-A through the lid according to FIG. 1 .
  • FIG. 3 is a further example with two axial sections A-A, B-B through the lid offset by 90°.
  • the lid 1 shown in FIGS. 1 and 2 as a first example of the invention is intended for a conventional drinks can body, which is not shown.
  • the lid is made from sheet metal having a thin wall thickness, as generally conventional.
  • lid panel 10 (as a panel) and a folded edge 11 for connection with an appropriate container.
  • a damping bead 12 (peripheral groove), which defines the lid panel 10 radially outwards, runs along the folded edge.
  • An ironed body is generally known and does not need to be described. It has an upper body edge, which is formed radially outwards as a flange and is closed by the folded edge 11 by a folding device (flanging roller) to form a multiple fold, mostly by the filler.
  • the folded edge 11 is arranged radially outside of the damping bead 12 , which is also called “peripheral groove”, and projects beyond the lid panel 10 at axial height.
  • the lid panel 10 itself also called a “panel”, is designed to be circular overall, but due to the opening 15 emerging significantly in size, which forms a cutout, essentially circular perforation in the lid panel, is still only partly present.
  • the cylindrical coordinates are used for the description, in radial direction (horizontal direction), the extension of the lid panel and in vertical or height direction, vertically to the plane E according to FIG. 2 , the axial direction.
  • the body itself is not shown, also the reclosing device 90 to be introduced into the opening 15 and to be assembled there on the edge, is not shown separately.
  • the opening 15 in FIG. 1 is shown with large dimensions in plan view. It is arranged off-centre, relative to its central point M 15 , which is offset with respect to the central point M 10 of the panel 10 by ⁇ M. Offsetting is selected to be between 5% and 25% in several exemplary embodiments, in the exemplary embodiment shown, it is in the range between 10% and 12% to 15%, in each case relative to the diameter d 10 of the panel 10 , which extends within the peripheral groove 12 . As shown d 10 is 2 ⁇ r 10 .
  • the diameter as an example of an opening dimension d 15 with 2 ⁇ r 15 of the perforation shown here in the example to be essentially circular is smaller than the diameter d 10 of the panel 10 , but greater than 50% of this opening dimension, which underlines the significant size of the opening 15 .
  • a first and a second peripheral strip surround the opening 15 .
  • the first peripheral strip 16 a borders directly on the edge of the opening and has two segment-like flat sections 15 b , 15 a at the inner side, which are opposite. They serve to improve assembly of the reclosing device 90 .
  • the second peripheral strip 16 has a radial dimension r 16 , which is greater than that of the first peripheral strip. It is formed in height direction above the plane E.
  • the plane E is placed in the opening 15 in horizontal direction and forms the comparison standard for height comparisons. It is the plane of the opening 15 , a two-dimensional extension within the plane is the opening surface. It describes the dimension of the opening 15 .
  • the peripheral strip 16 transfers via a gentle, in particular diagonally placed step 16 ′ into the inner peripheral strip 16 a .
  • the elevated peripheral ring 16 forms an annular pressure and support surface for a sealing and closing lip of the reclosing device 90 lying entirely at the same level.
  • the enclosing strip 16 runs completely around the opening 15 and delimits with respect to the peripheral groove on the left-hand side in FIG. 1 .
  • On the right-hand side in FIG. 1 it forms the limit to a plateau 20 designed to be sickle-shaped or part moon-shaped, which extends only partly peripherally around the perforation 15 . It is placed in that region of the lid panel, from which the opening 15 has been displaced in centre-offset manner. It is on the right side of the first axial centre plane extending vertically to A-A and through M 10 .
  • the partial enclosure is essentially 180° for circular design relative to the opening 15 .
  • the peripheral extension of the sickle-shaped plateau 20 is greater than 180°, in particular in the range between 200° and 240°, in particular in the region of 210° ⁇ 3%, relative to the periphery of the lid panel and the peripheral groove 12 .
  • the stiffening plateau has between these two ends 21 , 22 , a bulge 23 , which has its greatest radial extension in the central plane A-A and is tapered like an arc towards the ends 21 , 22 .
  • a further intermediate strip 17 which has essentially the same width on its peripheral extension, is provided between the plateau 20 and the peripheral groove 12 .
  • the peripheral extension corresponds to the extension of the arc of the plateau 20 and is in any case greater than 90°.
  • the two peripheral strips 16 and 17 have essentially the same width, designated in FIG. 1 by r 6 and r 7 . They also have essentially the same height position, easily seen in FIG. 2 with respect to the plane E.
  • Both the peripheral strip 16 and the peripheral strip 17 transfers via a preferably diagonal step 16 ′′ and 17 ′′ into the plateau region 20 , which lies at a deeper level, preferably slightly above the plane E in FIG. 2 .
  • An edge 20 ′ of the arc-shaped plateau 20 corresponds to these steps 16 ′′ and 17 ′′ and is designed as a preferably diagonal step in each case with at least one short diagonal section and two radii to pass over into the in each case adjacent region.
  • These diagonals 20 ′ form stiffenings.
  • the change between higher and lower positions (relative to a height direction), observed in a radial direction, on a “radius vector” (ray) from the centre M 15 forms a stiffening.
  • Leading-in of the outer peripheral strip 17 into the inner peripheral strip 16 takes place in the two lead-in zones 17 b , 17 a , which are directly adjacent the arm ends 21 , 22 of the plateau 20 .
  • Y-shaped or V-shaped zones are formed here, which are wider than the particular strip shape of the peripheral strips 16 , 17 .
  • the internal radius r 15 of the opening is shown in comparison to the radius r 10 of the lid panel.
  • the one or the other radius starts in each case from the centre M 15 or M 10 .
  • the radius r 15 is thus greater than half the radius of r 10 , in particular in the range above 60% between 60% and 65% of the main radius of the lid panel. This describes a large opening.
  • the man skilled in the art will understand “large” here in an optical relation to the size of break-open regions of drinks can lids normally expected to the priority date. When the man skilled in the art of cans compares the lengths of the radii, he would immediately say concerning r 15 : “This has been chosen quite large”.
  • the central offset ⁇ M in various exemplary embodiments lies between 5% and 25%. They change inasmuch as the size of the opening 15 also has a clearance and range, and the shape of the opening also has a clearance and range, which may deviate from the exact circular shape, for example polygonal or oval. It is at least approximately polygonal or oval.
  • the ⁇ M central offset lies between 10% and 15%.
  • An up-and-down is produced in radial direction, that is a change in height positions (level change), in particular in that region of the lid the opening 15 is displaced (centre-offset) from and in which the sickle-shaped plateau surface 20 is introduced without further additional stiffenings or additional beads.
  • the change of height positions takes place from radially inwards to radially outwards (in a staggered form), starting from the inner edge strip 16 a (around the opening 15 ), to the first enclosing strip 16 , to the stiffening plateau 20 , to the further intermediate strip 17 and finally via the peripheral bead 12 to the peripheral edge 11 .
  • Diagonally running steps are preferably arranged between these areas, as previously described using the step 20 ′ of the stiffening plateau 20 (as an essentially flat surface having a large extension).
  • the change of height levels of the geometric stiffening shapes 16 a , 16 , 20 , 17 , 12 , 11 can be seen in section in FIG. 2 .
  • Each of the stiffening geometries extends peripherally over at least 90°, as subsidiary lines C-C in FIG. 1 illustrate. They define an angle of 90° and all stiffenings extend far beyond it in peripheral direction, reaching 180° and even 360° for individual peripheral stiffenings.
  • the opening 15 is not covered by sheet metal, but is open. It has a free inner edge 15 a . It is centre-offset (relative to the diameter of the panel) between 5% and 25% and the first enclosing strip 16 surrounding it reliably retains the same height position to facilitate a sealing function.
  • the further exemplary embodiment according to FIG. 3 follows the first exemplary embodiment with two sections A-A, B-B.
  • FIG. 3 The remaining descriptions regarding FIG. 3 may be assumed from the preceding exemplary embodiment.
