Definitions

  • This invention is particularly concerned with improved lightweight closure caps usable for the closing and sealing of openings in bottle necks and of other containers having comparable openings where resistance to substantial pressure within the container during shipment and storage thereof is a requisite while at the same time destructibility and removal of the cap by hand action without the use of any tools can be readily achieved. Additionally the invention is particularly concerned with methods for forming such caps and particularly for providing destructibility of the same when desired by the user without that provision for destructibility introducing the likelihood of fracture or failure under pressure into such caps as they are sealingly secured about the container opening.
  • the weakening, if not real fracturing, of the metal of the caps remaining in back of the scores after scoring developed in two stages.
  • the first of these stages was in the forming of the caps and the second was in the applying of them to the containers.
  • the skirt in its extent from the bend to the lateral free edge thereof would be subjected to increasing destructive forces due to the moving of the same strip of metal into a position where it occupied less space than it did while laid out in the flat. This imposed a compressive action upon the metal which could be relieved if the cap skirts were permitted to pucker, thus extending their area. Puckering, however, is unsightly and undesirable so is to be avoided. With caps having their skirts thus scored in the fiat, there is nothing to prevent this puckering action from manifesting itself instead in the reducing of the width of the score and while doing so, exerting a weakening, bending action on the thin wall of metal in back of the score.
  • the securing of the caps could be achieved in a number of Ways, for example, by a spinning tool having inwardly urged rotating elements to move the metal of the cap inwardly or by means of a multi-jawed crimping tool crimping the cap inwardly without leaving any space for the puckering of it.
  • the forces applied to affect this sealing are quite substantial and they were applied to prior art cap skirts already weakened by the action of forming them out of the flat after scoring. Again the destructive forces would be focused on the thinnest part of the metal. In many instances the caps would be weakened beyond the critical point at which they no longer resist the pressures in the containers which they were intended to seal.
  • Caps made in accordance with the invention are free of the first and most acute of these two destructive factors inasmuch as no weakening of the metal beyond the thinning of it is effected in the cap manufacture. Accordingly little appreciable weakening is effected in the second step, the applying of the caps such as by spinning or crimping as just described.
  • the caps of the invention are formed by means of a method wherein fiat blanks are scored at the same instant they are being formed in the desired cup or cap shape.
  • the skirts are scored first, such scoring commencing at the periphery of the cap top or where the skirts are bent out of the fiat and then continuing down to the free edge of the skirt.
  • cap blanks may be sheared from the strip, or be provided already sheared and then be formed into the general cup-shape of a cap while being scored as well all in the single stroke of a press.
  • Another object is to provide a novel method for manufacturing such caps.
  • Still another object is to provide such closure caps, which though readily destructible and removable when intended, are stronger and more pressure-resistant than closure caps of comparable size and material heretofore made.
  • Still another object is to provide such closure caps which though scored for destructibility and ready removal are weakened to a minimum extent in the securing of them to container openings.
  • a further object is to provide a method for forming such caps which, in spite of substantial scoring of the same, retains the strength of the cap to the fullest extent possible.
  • Still another object is to provide such method which is productive of scores in the finished cap which are substantially uniform throughout in cross-section.
  • a still further object is to provide such a method which avoids deformation or straining of the metal remaining in back of the scores.
  • a still further object is to provide apparatus for carrying out the method of the invention.
  • a more detailed object is to provide a method for forming internally scored closure caps having a top and a skirt extending therearound wherein scoring formed in the skirt is unaffected by the forming of the skirt from the flattened to a laterally extending position with respect to that flat.
  • Another detailed object is to provide a method for simultaneously forming the skirt of a closure cap laterally from a flat blank while scoring the same internally.
  • FIG. 1 is a plan view of the cap blank for use in forming the closure cap of the invention.
  • FIG. 2 is a vertical section including the blank of FIG. 1, taken on line 2-2 thereof, of die elements for performing the method of cap forming in accordance with the invention showing those die elements in their initial position with the blank therebetween ready for the commencement of the forming.
  • FIG. 3 is a fragmentary perspective view partially broken away of the die elements and blank at an inter mediate stage in the method of forming the cap.
  • FIG. 3A is a greatly enlarged fragmentary vertical section taken through the score knife of the cap and die elements in the position of FIG. 3.
  • FIG. 4 is a vertical sectional view with a part of the cap skirt broken away showing the final forming stage.
  • FIG. 5 is a greatly enlarged fragmentary perspective view of the scored portion of the cap formed in accordance with the invention as viewed from the inside thereof.
  • FIG. 6 is a perspective view of a completed cap in accordance with the invention with a fragment of the nonscored portion of the skirt broken away to expose the interior thereof.
  • FIG. 7 is a greatly enlarged fragmentary vertical sec tion of a cap applied to a container neck.
  • the closure cap of the invention is shown per se in FIG. 6 Where it is generally indicated at 1. It has a disclike top 2, surrounded by a downwardly extending skirt 3 from the free edge 4 of which a tearing ear 5 extends laterally outwardly. Where the parallel sides 6 and 7 meet the edge 4 at the positions 8 and 9, the internal scores in accordance with the invention commence. These scores have parallel portions 10 and 11 shown in detail in FIG. 5
  • the scores continue in portions 14 and 15 around the inside of the rounded portion 12 and then extend substantially across the top 2 of the cap in continuing parallel portions 16 and 17. These portions 16 and 17 as here shown terminate at the positions 18 and 19 adjacent a portion of the cap diametrically opposite from the rounded portions 14 and 15 of the scores. Considering the light weight of the material used for these caps, the scoring is adequate if it terminates at the positions 18 and 19 for when the tearing of the tear strip 21 between the scores has continued that far, the separated portions 21 and 22 of the cap will have been sufficiently freed from each other that at the end of the tearing action, the cap will come right off the container neck to which it is applied.
  • the portions 10 and 11 have the same Width and depth from their commencement at 8 and 9 to the rounded portions 14 and 15. That same uniform width and depth also continues around the rounded portions at 14 and 15 and, likewise continues across the top of the cap in the portions 16 and 17.
  • This uniform scoring throughout having been effected by a method of manufacture about to be described makes it quite clear that the material remaining in back of the scores remains of the same thickness and has the same undistorted condition from the commencement of the scores at 8 and 9 throughout the full extent of the portions 10 and 11, 14 and 15, and 16 and 17.
  • the cap has a gasket 25 secured therein.
  • This gasket is preferably formed in situ within the cap and results from the applying of material in fluid form which, when suitably heated, sets up into the form of a resilient gasket and is adhered to its seat within the cap. As seen, the gasket extends part way in beneath the top of the cap at 26 and part way down the skirt of the same to the position 27.
  • An important aspect of this gasketing resides in the fact that as the fluid material out of which the gasket is made is flowed across the rounded portions 14 and 15 of the internal scores, a certain amount of it flows into those scores, as shown at 18 in FIG.
  • the cap of the invention possesses the greatest strength and greatest resistance to leakage of any scored cap heretofore devised in lightweight material.
  • FIGS. 1 through 4 The method by which the cap blank is given the uniform scoring in accordance with the invention, is illustrated in FIGS. 1 through 4.
  • the initial form is a flat blank 26 as shown in FIG. 1. This may be stamped out of a flat sheet as an integral part of the forming operation or may be brought to the forming stage in a blank as seen in FIG. 1. What is significant to note, however, is that the blank is in no way scored while in the flat leaving all of the scoring to be effected along with the forming of the blank into the cap. Turning then to FIG. 2, the blank 26 of FIG.
  • the forming anvil 30 has an outer cylindrical surface 32 of the size desired for the interior of the cap while the drawing die 31 has an inner cylindrical surface 33 whose diameter is equal to the diameter of the wall 32 of the forming anvil plus twice the thickness of the blank 26 and leaving enough additional clearance to enable the drawing die to move down over the forming anvil with a blank therebetween and to be thereafter retracted therefrom.
  • the forming anvil 30 is provided with pair of scoring knives 34 and 35 extending outwardly from the cylindrical surface 32 thereof to the extent needed to effect the desired scoring in the cap.
  • the knife portions 34 and 35 clearly shown in FIG. 3, continue at their upper ends in rounded portions 36 and 37 which are accurately aligned with and continue into parallel knife portions 38 and 39.
  • the portions 38 and 39 extend across and project up from the otherwise flat top 40 of the forming anvil 30.
  • These knife portions have uniform cross-sectional shape throughout, are accurately aligned and are continuous for each knife. They may be provided in various manners as would readily suggest themselves to one skilled in the art, but for the present and for the consideration of the method involved, it is only necessary to appreciate that they are formed on the forming anvil and project outwardly therefrom.
  • the drawing die 31 has moved down to an intermediate position where first its bottom flat face 41 and then its rounded entrance surface 42 extending from the face 41 to the inner surface 33 has engaged the upper surface of the blank 26 and has turned the peripheral portion 43 of that blank around the rounded edge 44 where the side wall 32 of the forming anvil turns into the top 40 thereof.
  • the peripheral portion 43 of the blank has been moved down towards a vertical position with the intermediate portion 45 between the top and the portion 43 of the blank being turned down around the rounded surface 44 of the forming anvil.
  • the wiping action imparted to the metal lying in back of the score during the formation thereof does not have the hardening effect which results when the prior art blank is scored in the flat. It can readily be appreciated that any brittlness in the scored are-a such as results from hardening in prior art methods is a detriment.
  • the instant invention discloses a method for making closures from which flow advantages in terms of economy and manufacturing efliciency of substantial importance.
  • the closure cap so formed is characterized by the complete absence of fracturing or weakening of the thin layer of metal in the skirt lying behind the score line. It has been found that even though the skirt of the cap is severely deformed in the application of the cap to a container neck, the cap will remain fully effective due to this structural imporvement. Furthermore the ease with which the closure cap of the invention can be torn off of a container neck is greatly enhanced since a relatively deep score can now be made in the metal without fear of detrimental weakening at this point. Such features make this closure particularly well-suited for the capping of beer or soft drink bottles where substantial internal pressures are present and ease of opening is an essential re quirement.
  • a lightweight metal closure cap of the type adapted to be formed over a lip bordering the opening of a container neck said cap comprising a flat disc-like top portion, a cylindrical skirt depending from and around said top portion, a pair of score lines commencing at the free end edge of said skirt extending up said skirt and continuously across said top, said score lines establishing a tear strip therebetween, a single tearing ear extending laterally outwardly as an integral extension of said tearing strip from the free edge of said skirt at the commencement of and between said score lines, an annular gasket formed in situ within said cap and extending from a position closely adjacent the periphery of said top to a position part way down said skirt, said score lines in said skirt being uniform in cross-sectional depth and width throughout their length, said score lines in said skirt having been formed by the simultaneous scoring of the interior of said skirt while forming the cap from a flat blank by drawing an annular peripheral portion of said blank laterally from the plane of said blank while supporting the center circular portion of said blank and scoring said annular peripheral portion as
