Definitions

  • the skirt portion 21 which connects with the lower end of the skirt portion Ztl is both outwardly and downwardly ilared and the middle of this double-curved portion 2l constitutes a shoulder intermediate the inner step portion 2% or the skirt and the outer, substantially straight or vertical, portion 22 thereof which carries the bead 1l and lugs l2.
  • the gasket lll includes a main cushion portion 23 which completely tills the downward channel l5, and a downwardly and outwardly tapered elongated portion L4 which follows ⁇ down along the inside of the tapered portion 20 of the cap shell. terminates in an outwardly ilared feather edge portion 25 which actually ends at approximately 26 underneath the shoulder portion of the shell. it will be seen that the upper edge of the gasket lli terminates on the underside yof the top panel portion 7 adjacent the bottom end of the channel forming wall i6, as indicated at 27.
  • the gasket ltl may be formed of various known rubber-like resilient gasket materials having the desired physical and chemical properties.
  • a preferred class of materials from which the gaskets lo may be formed are the resin compositions known in the art as plastisols
  • a preferred plastisol type gasket composition is described in detail in Unger :and Zipper Patent No. 2,874,863.
  • the gaskets itl may be deposited in the cap shells by various known techniques, one being the so-called ilowed-in technique wherein the plastisol composition is uncured, paste-like condition is squirted' from one or more nozzles into the cap shells (at position 8 cap shell portion FIG. 5) whichare turned upside down on a chuck rotating at high speed.
  • the proper amount of gasket material can be deposited in the corner portion and then it can be correctly shaped by a forming die which may also be heated ⁇ so as to simultaneously shape and cure the gasket material.
  • the present invention is not particularly concerned with either the details of the gasket composition or the particular technique used in forming it into the gaskets 1t?. Rather, any suitable rubber-like resilient gasket material having the proper physical and chemical properties may lbe used, and any suitable manufacturing techniques may be employed.
  • the sealing finish of the glass jar 5 comprises a top edge portion 3G which merges with a :beveled ortapered side seal portion 3l.
  • the relative relationship of the gasket lil, and the glass finish when the closure cap 6 is in'fully sealed position are shown .in FIG. 7.
  • the closure caps d are applied to the iilled glass jars S and turned Y down to fully sealed position thereon in known manner using lnown high speed capping equipment. Generally, this 4combined capping and sealing operation begins with applying the caps loosely onto the mouths of the jars At its lower end, the gasket lo f CIT passing through an atmosphere of steam, and then turning the caps down lightly to position with the lugs 12 engaging underneath the glass lugs l.
  • the gasket lil in combination with the cap shell and the sealing nish on the rim of the container.
  • the rst seal is formed at the feather edge 26. Since this seal is located at a relatively remote distance from the portions of le gasket which are engaged with the glass iinish, and because of the thinness of the feather edge portion and the inability thereof to transmit compression forces, this feather edge seal at Z6 is fully protected and easily maintained so that no part of the atmosphere has an opportiunity to gain entrance between the gasket l@ and the cap shell portion S.
  • the second portion of the seal is in the area where the thinned out, tapered skirt portion 24 of the gasket is maintained under radial compression between the distended portion 35 ol the cap shell and the unyielding opposing tapered nish 3l.
  • the leakage rate in this portion of the seal is reduced to a minimum since it will be seen that for any part of the atmosehere to pass this seal it will have to traveL through the gasket, not cross-wise or transversely in the narrow direction but lengthwise and parallel to the drawn out portion. Hence, for practical purposes there is no leakage to speak of through this portion of the seal.
  • closure cap 6 described above in detail in connection with the accompanying drawings represents the presently preferred embodiment of my invention.
  • the cap shell on the lower portion of the skirt could be provided with thread formations rather than the lugs l2 so as to he a screw cap for cooperation with exterior threads on the glass finish.
  • the exterior diameter of the bottom or outermost skirt portion 22 may be reduced somewhat, and -minor variations may he made in the contour of the upper ⁇ stepped portion of the shell. Minor variations may he made in proportions.
  • a closure cap of the -top and side seal type for use in establishing and maintaining a hermetic seal on a glass container of the type in which the upper edge of the rim together with a portion of the side surface thereof constitute the hermetic sealing finish
  • said cap coniprising a generally cup-shaped shell having a top panel portion with the margin having a down-turned channel formation to register with said upper edge and having a stepped skirt portion with the upper inner step thereof integrally joining the outer wall of said channel formation as a continuation thereof and providing a downwardly and outwardly tapered side portion the bottom of which directly joins an outwardly flared shoulderportion
  • the improvement comprising an annular sealing gasket located generally within the corner of said shell having its upper and inner edge located on the underside of said top panel portion adjacent the bottom of the inner side wall of said channel formation with its lower and outer edge terminating in ⁇ a feather edge on the under-side of said outwardly flared shoulder portion, with said gasket filling said channel formation and having a downwardly and outward
  • a sealed package comprising a glass container having a hermetic sealing finish provided in part by the top edge of the rim and in part by a contiguous downwardly tapered side surface and having protruding cap-retaining means helow said finish and a closure cap in hermetically sealed relationship on the top of sai-d container, said cap comprising a generally cup-shaped shell having a top panel portion with the margin thereof having a down-turned channel formation in registry with said top edge of said sealing finish and having a stepped skirt portion with the upper inner step thereof integrally joining the outer wall of said channel formation as a downwardly and outwardly tapered continuation portion which telescopes over said tapered side surface of said sealing nish with the lower end thereof directly joining an outwardly and downwardly flared shoulder portion of said skirt which in turn directly joins a lower outer step portion of the skirt which has inwardly protruding ⁇ cap-retaining means in engagement with said cap-retaining means on said finish, and an annular sealing gasket locate-d generally within the corner of said shell having its
