Definitions

  • Holler ABSTRACT A sheet metal closure cap embodying a tearstrip extending diametrically of the panel and defined by two opposed scores extending from points in the upper areas of the v CLOSURE CAP ron CONTAINERS RELATED APPLICATION
  • the present invention is a continuation-in-part of copending application, Ser. No. 579,911 filed Sept. I6, 1966, now abandoned.
  • An object of our invention is the creation of a so-called convenience" closure cap providing an external side seal o n the container involved and incorporating novel effective cap removal means which will not detrimentally affect either the ease of cap application or its ready removal by hand and without resort to the use of special tools.
  • a further object of our invention is the provision of a sheet metal closure cap, aluminum for example, embodying a novel form of tear-strip" and pull-ring arrangement which will facilitate easy removal of the cap and with no danger of injury to the person of the individual involved.
  • a still further object of our invention is the provision of a closure cap of the above character embodying a tear-strip defined by a pair of scores or score-lines which, while effective in facilitating cap removal do not extend far enough into the attaching skirt to adversely affect the skirt-rolling operation.
  • the scores are of sufficient depth to make cap removal quite easy they are not located even in part, in the path of the rolls which constrict the cap skirt into firm holding engagement with the bottle or such container.
  • FIG. 1 is a fragmentary perspective view showing a closure cap embodying our invention affixed to a container.
  • FIG. 2 is a transverse sectional view of the cap and fragment of the bottle shown in FIG. 1, wherein the sealing element or liner does not extend across the mouth of the bottle.
  • FIG. 3 is a view like FIG. 2 but with the sealing element closing the bottle mouth and the tear-strip so formed that there is a small generally transverse slot at the point of initial tear-strip separation thereby. to facilitate initiating such separation.
  • FIG. 4 is a fragmentary detail sectional view showing the initial step involved in securing the pull-ring to the tear-strip wherein the apertured ring is slipped over the hollow upstanding boss.
  • FIG. 5 is a view like FIG. 4, but with the boss reshaped to form an annular locking bead or shoulder overlying the aperture wall.
  • FIG. 6 is a fragmentary plan view of the tear-strip with the transverse slot embodied in the structure of FIG. 3.
  • FIG. 7 is a sectional view of another form of ring connector.
  • This cap which is formed of sheet metal and preferably aluminum, comprises a panel 14 or top portion and a peripheral depending attaching skirt I5 or flange. A small radius l6 joins the panel and skirt. Within the cap is an annular sealing ring 17, gasket or liner, such lying against the interior surface of the skirt l5 and radius 16. If preferred, this sealing means may be a cuplike element of plastic or other suitable material covering the entire surface of the cap. The choice may well be dictated by the product being packaged and/or the specific tear-strip construction as will be explained later herein.
  • closure cap to a filled bottle involves merely telescoping the gasketed cap over the neck 10 and bringing rollers (not shown) of conventional apparatus (not shown) into rolling engagement with the lower fraction of the skirt exterior.
  • This conventional procedure contracts the skirt l5 and presses the gasket firmly against the sealing surface 13 and constricts the skirt to a diameter somewhat less than that of the neck itself, thus insuring against cap displacement and leakage or loss of product.
  • a tear-strip 18 extends diametrically across a major fraction of the cap panel 14 being defined by two straight convergent side scores 19 such that the wide or broader end of the strip is at or adjacent the periphery of the panel while the other end is near, though slightly beyond the panel axis. At the narrow end, the two scores 19 are joined together by an arcuate score 20.
  • a single radial score 21 extends from the medial point of this arcuate score 20 to the nearest point of the radius 16 at the panel periphery.
  • the other or convergent scores 19 extend into the radius 16 (FIG. 1) with one of them extending well into the skirt proper but terminating in the upper fraction of the skirt or in any event not below the median point, height wise. Thus, there is no score in the path of the skirt-constricting rollers.
  • a pull-ring 22 which though preferably formed of polyethylene or some similar plastic material, may be of metal. It is of substantial diameter to facilitate ready firm grasping and is anchored to the narrow end of the tear-strip 18.
  • the anchoring means is a drawn hollow rivet 23 produced by initially forming a hollow upstanding boss at the small inner end of the tear-strip. This boss enters an aperture 24 in the pull-ring and then is crushed axially to produce an annular retaining shoulder or bead 25 which secures the ring to the strip. It will be observed that the pullring 22 is widened substantially at its point of connection to the strip to increase its strength and resistance to rupture.
  • this pull-ring 22 encircles the small end of the tear-strip and normally lies flat against this strip and the panel. It will therefore be apparent that quite in contrast to the customary procedure involving inserting a finger tip or finger nail beneath an end of the tear-strip and thereby initiating actual strip separation, our novel arrangement permits one to first lift the pull-ring with ease to a position at which it may be grasped firmly before any strip-tearing is in fact initiated. Then the pull-ring is drawn generally toward the cap periphery and thence in a direction about the cap skirt, such completing the cap-removing operation. Thus, instead of using only one finger to initiate tear-strip separation two or more fingers grasp the pull-ring, thereby enabling one to exert maximum force at the outset in tearing the strip along the scores 19.
  • one score 19 extends well into the skirt.
  • the pull-ring 22 is lifted to perhaps the dotted line position (FIG. 3) and'then is pulled upwardly and laterally separating the strip along the scores 39 and completely across the skirt at the single score which extends well into the skirt.
  • the ring and strip are pulled in a generally clockwise direction so as to break the cap panel along the score 2i, thereby completing the cap removal operation.
  • the sealing ring may be removed with the cap or pulled off as a final step.
  • cap removal involves grasping the pull-ring 22, lifting same and then pulling it in an upward direction along the length of the str 9 toward the cap periphery and thence in a circular direction about the cap axis until the panel separates along the score 21. Until such removal is desired, the tapered or curved sealing surface 13, effectively holds the cap'against axial displacement.
  • FIG. 7 we have shown another form of connector fastening the tear-strip l8 and pull-ring 22 securely together.
  • the head of rivet 23 is thereupon, flattened, as shown, to secure the pull-ring 22 to the tear-strip 18.
  • the collar portion may be omitted so that the flange 28 in effect becomes the equivalent of a collar or simple washer.
  • a closure cap for a container having a mouth opening defined by an annular rim and including outwardly of said rim an annular downwardly and inwardly tapering sealing surface comprising a metal cap element having a top panel portion, a depending attachedannular skirt joined peripherally with said panel portion, the annular skirt being telescoped over said rim and contracted tightly about said sealing surface, a prescored tear-strip integral with said metal panel portion and skirt and defined by a continuous score comprising a pair of unequal length divergent, radially outwardly directed scores, the shorter one of said scores terminating in the skirt and the longer one of said scores extending into the skirt to be at least in close proximity to the lower edge of the latter, said pair of scores beginning in the central region near the axis of said panel portion and merging in said region, pull-ring means and means attaching said pull-ring means to the one end of the tear-strip adjacent the said merged scores, the attached pullring being disposed substantially flat against the portion of the tear-strip in the top panel and said
  • the tear-strip includes a slot in the metal along said score in the top panel opposite the location of attachment of said pullringmeans'on the tear-strip, said means being disposed intermediate said slot and said terminal ends of the pair of scores, thereby minimizing resistance to initiation of tearing of the strip upon operating said pull-ring means.
  • Tli'lifih'ap defined irT'ElaiinT, wlTei-EE ihEUSst'iY cap includes a liner underlying the top panel portion of the metal cap element.
  • closure cap defined in claim 3, wherein the liner comprises a cuplike element of plastic material interposed between the metal cap element and the container, engaging the annular sealing surface of the container and covering the mouth of the container.
  • a two-piece closure cap for a glass container having a mouth opening defined by an annular rim and including, outwardly of said rim, an annular downwardly, inwardly tapering sealing surface
  • an elastomer cap element having an annular sealing ring and an integral, annular, downwardly and inwardly depending sidewall, said sealing ring engaging over the annular rim of said container mouth, said sidewall having a minimum internal diameter less than the maximum external diameter of said rim, said elastomer cap element adapted to snap-fit over said container rim and engage said sealing.
  • a metal cap element'nestingly overlying said elastomer cap element comprising a panel portion, a depending attached skin about the periphery of said panel'portion, a continuous prescored tear-strip integralinsaid metalpanel portion and skirt and defined by a pair of radially, outwardly directed scores each beginningin the central region of the" top panel, one of said scores terminating in the skirt and the other of said scores extending farther along the skirt terminating at least in close proximity'to the lowerper' ipheral edge of the latter, and an arcuate score merging with said pair of scores in said central regionof: the top panel, pull-ring means, and means attaching said pull-ring means to said-tear-strip adjacent said arcuate score and disposed substantially flat against the tear-strip and encircle said arcuate score, said pullring means operating as a lever thereby initiating severing the tear-strip upon raising the pull-ringsubstantially, the unequal length scores providing for removal of the metal cap element
  • A' convenience opening closure comprising a tear-strip portion therein defined by means weakening the closurealong a predetermined path, a pull removal device for sever ing said'tear-strip portion, a fastener attached'to said tearstrip and having a head portion to be applied in firmly .con-
  • said device including an aperture receiving said fastener prior to application of the head portion thereof, and a preformed collar in said aperture and interposed between said fastener and said device, the head of said device being applied and covering said collar to firmly engage said collar.
