Definitions

  • the present invention relates generally to containers and more particularly to an improved finish for glass containers such as bottles which are sealed by means of closures of the type known as crown closures or caps.
  • Glass containers or bottles of the type contemplated in the instant invention wherein the closure and sealing thereof are effected by means of a standard metal crown closure, are commonly employed to contain carbonated beverages or other liquids capable of exerting internal pressure.
  • a standard metal crown closure typically, such glass bottles have the so-called standard glass finish or crown finish, which includes a circumferential radially outwardly projecting bead having a rounded profile, adjacent their opening or mouth.
  • the gasket or liner is initially compressed between the metal of the crown cap and the generally upwardly facing sealing surface of the standard glass finish at the mouth of the bottle to form a seal therebetween.
  • a suitable die means engages the fluted ski-rt portion of the crown closure so as to radially compress and deform the fluted skirt portion of the closure inwardly so as to grip the aforementioned bead portion of the finish to thereby maintain the seal.
  • a principal object of the present invention is to provide an improved finish for glass containers and bottles for use with crown closures.
  • Another object of the present invention is to provide an improved finish for glass bottles so as to permit the sealing and unsealing of the bottle by means of a standard crown closure without excessive deformation of the crown closure.
  • a further object of the present invention is to provide an improved finish for glass bottles which are to be sealed by standard crown closures, wherein the crown closure may be readily removed from the bottle and reapplied by hand to effect a tight seal.
  • An additional object of the present invention is to provide an improved glass bottle which is adapted to be sealed by a standard crown closure wherein the crown closure may be readily removed from the "bottle without the necessity of employing specially designed tools or openers.
  • Another object of the present invention is to provide a bottle sealed by a standard crown closure wherein only slight deformation of the crown closure is necessary to effect removal thereof and such removal may thereof by removal of the crown closure without the use of special tools or openers but with commonly available lever means such as coins or the like and without substantial deformation of the crown closure so that the surface 30 having a radius R in radial section.
  • FIGURE 1 is a side elevational view of the neck portion of a glass bottle embodying this invention
  • FIGURE 2 is a fragmentary plan view of the glass bottle shown in FIGURE 1;
  • FIGURE 3 is an enlarged fragmentary sectional view of the top profile of the glass bottle shown in FIGURE 1;
  • FIGURE 4 is a side elevational view, partly in section, of the neck portion of a glass bottle embodying this invention with the mouth of the bottle sealed by a standard crown closure according to this invention;
  • FIGURE 5 is a fragmentary sectional view showing a specific dimensioned example of a crown closure receiving finish embodying the present invention.
  • FIGURES l, 2 and 3 of the drawings there is shown a fragmentary portion of a glass container or bottle having a neck portion 12 provided at the open upper end or mouth portion 14 thereof with a crown closure receiving finish 16 and an annular outwardly extending shoulder or shelf'18 spaced therebclow.
  • the finish 16 generally comprises a thickened or transversely enlarged portion at the mouth portion 14 of the bottle and will be seen to include an annular generally upwardly facing flat sealing surface 20 extending transversely to the longitudinal axis X of the neck 14, an outwardly facing longitudinally extending cylindrical surface 22 concentric to the axis X and an annular upwardly diverging beveled or conical closure gripping surface 24 extending obliquely to the axis X.
  • annular sealing surface 20 can extend in a plane normal to the axis X and thus be normal to the cylindrical surface 22, as shown in the drawings, it has been found that its sealing function will not be impaired while the molding of the half sectionsforming the bottle will be facilitated if the sealing surface 20 is inclined slightly to the normal plane so as to extend both outwardly and slightly downwardly of the axis X as shown by the dotted line 20 in FIGURE 3. This departure or inclination from a plane normal to the axis X need only be very slight, generally not exceeding about 5 as indicated in FIGURE 3.
  • the upwardly facing sealing surface 20 is connected to the interior inwardly facing cylindrical wall surface 26 of the bottle 10 by an annular outwardly flaring arcuate inner transition or edge surface 28 having a radius B in radial section.
  • the outer cylindrical surface 22 is connected to the upwardly facing sealing surface 20 by the annular inwardly flaring arcuate outer transition or edge
  • the disposition of the conical gripping surface 24 relative to the cylindrical surface 22 is such that the oblique exterior angle A formed by the intersection of the conical surface 24 and the cylindrical surface 22 with a vertical plane is within the range of 210 to 230 degrees and preferably about 225 degrees.
  • the conical gripping surface 24 and the outwardly facing cylindrical surface 22 meet at a relatively sharp slightly rounded annular gripping edge surface 32.
  • the gripping edge surface 32 be relatively sharp, and that it have at most a very small radius R
  • the radius R should not exceed 0.025" and is preferably in the range of 0.0lO"-0.01S" for sealing a glass bottle 10 with a standard crown closure.
  • the annular outwardly extending shoulder 18 which is spaced axially below the conical gripping surface 24 includes an upwardly facing fiat annular bearing or camming surface 38 extending radially outwardly from the reduced cylindrical neck portion 34 in a plane substantially normal to the axis X.
  • the upwardly facing annular cammin'g surface 38, the reduced cylindrical neck portion 34 and the conical gripping surface 24 will be seen to define an annular space or slot 40 underlying the finish 16.
  • the upwardly facing annular cam-ming surface 38 should be spaced below the conical gripping surface 24 such that when a standard crown closure is in operative sealing engagement with the finish 16 a sufficient space exists between the lowermost extremity of the skirt portion of the crown closure and the surface 38 to permit the insertion of a suitable camming instrument such as a coin or the like into the annular slot 40, as will be more fully described hereinafter.
  • FIGURE 4 of the drawings there is shown the neck portion 112 of the glass bottle 10 with a standard crown closure 42 secured in operative sealing engagement with the closure receiving finish 16.
  • the standard crown closure 42 includes a sheet metal shell 44 having a top portion 46 and a depending fluted skirt portion 48 terminating in a lowermost peripheral edge 50.
  • the fluted skirt portion 48 is provided with inwardly directed flutes 52 alternating with outwardly directed rib forming pleats 5-4.
  • a gasket or liner 56 of compressible molded resilient material such as a suitable thermoplastic or elastomeric material compounded so as to be odorless and tasteless and to be free from effects on, or to be affected by ordinary foods or liquids which may be stored in the bottle 10.
  • a suitable thermoplastic or elastomeric material compounded so as to be odorless and tasteless and to be free from effects on, or to be affected by ordinary foods or liquids which may be stored in the bottle 10.
  • the liner 56 comprises a vinyl chloride plastisol such as has been illustrated in US. Patent 3,002,641.
  • the plastisol liner 56 will be seen to have been deformed during the capping operation so as to conform to, and be in intimate sealing engagement with, the upwardly facing sealing surface 20, the inner transitional edge surface 28 and the outer transitional edge surface 30 of the closure receiving finish 16. Such deformation of the liner 56 will cause an inwardly disposed annular ridge 58 to be formed therein which is in sealing engagement with the inwardly curving inner transitional edge surface 28.
  • the fluted skirt 48 of the crown closure 46 has, under the influence of a suitable capping die (not shown), been crimped by being sharply bent or deformed inwardly as at 60 about the small radius R of the relatively sharp annular gripping edge surface 32 so as to form and dispose therebelow relatively short locking or gripping shoulders 62 in intimate gripping contact with the conical gripping surface 24.
  • the locking or gripping shoulders 62 which are formed by lower portions of the flutes 52, will be seen to define a relatively short downwardly extending, inwardly converging, gripping surface which merges with the outwardly diverging or flaring flute portions of the lowermost marginal edge portion 64 of the fluted skirt 48 in a knee-like radially inwardly facing arcuate surface 66.
  • crown closures As is well known, the removal of such crown closures from sealing engagement with a standard glass finish requires rather severe permanent deformation of the closure as well as special tools or openers which are capable of readily effecting such severe deformation. Of course, such severe permanent deformation of the crown closure precludes its reapplication to the standard finish to effect a rescaling of the bottle.
  • the gripping shoulders 62 need extend only a relatively short distance inwardly of the largest outside diameter of the finish 16.
  • a minimum or limited amount of distortion of the crown closure 42 is necessary to effect sufiicient outward movement of the fluted skirt portion 48 so as to permit the kneeJike arcuate surface 66 to clear the outer cylindrical surface 22 of the finish 16 and thereby effect removal of the crown closure 42.
  • crown closure 42 Any permanent deformation of the crown closure 42 which may occur during removal of the closure will be slight since most, if not all of the relatively slight outward distortion of the fluted skirt portion 48, necessary to permit release of the grip of the closure 42 on the finish 16, will be elastic because of the inherent or natural resiliency of the metal shell 44.
  • removal of the crown closure 42 can be readily effected by simply inserting -a suitable lever means such as a coin 68 in the annular slot 40 so as to dispose a marginal edge portion of the coin between the lowermost peripheral edge 50 of the crown closure 42 and the upwardly facing flat carnming surface 38 of the annular outwardly extending shoulder 18 and then rotating or twisting the coin 68 relative to the slot 40, as shown by the arrows B and B so that the underside of the coin engages the cumming surface 38 while the upper side of the coin engages the lowermost peripheral edge 50 of the crown closure 42.
  • a suitable lever means such as a coin 68 in the annular slot 40 so as to dispose a marginal edge portion of the coin between the lowermost peripheral edge 50 of the crown closure 42 and the upwardly facing flat carnming surface 38 of the annular outwardly extending shoulder 18 and then rotating or twisting the coin 68 relative to the slot 40, as shown by the arrows B and B so that the underside of the coin engages the cumming surface 38
  • such outward camming of the knee-like arcuate surface 66 so as to permit removal of the crown closure 42 may be effected by depressing the outer edge of the coin 68, as shown by the arrow C in FIGURE 4. While a coin has been illustrated as a means for effecting removal of the crown closure, it will be apparent that many other flat implements such as keys and the like which are also commonly available can be similarly employed as a suitable lever or carnming means.
  • FIGURE 5 of the drawings there is shown a specific dimensioned example of a crown closure receiving finish 116 for a glass bottle adapted to receive a standard crown closure according to the present invention.
  • the dimension of the finish 116 are as follows:
  • the fluted skirt portion of the crown closure was crimped inwardly, as aforedescribed by reference to FIGURE 4 of the drawings, so as to have a minimum crimped diameter of 1.210 below the glass finish 1'16. This dimension should be contrasted with the considerably smaller corresponding crimped diameter of about 1.130" which is necessary when a similar standard crown closure is applied to a standard glass finish.
  • the standard crown closure so applied to the finish 116 maintained its initial seal under an internal container pressure of pounds. After removal and reapplication of the crown closure, in the manner aforedescribed, the reestablished seal was maintained under 30 pounds of container pressure, which is adequate for mos-t carbonated beverages stored under refrigeration.
  • the neck portion 112 of the bottle 110 differs from that of the neck portion 12 of the bottle 10 aforedescribed in that the annular outwardly extending shoulder 118 is in the form of a radial flange, the underside of which merges with .the below disposed reduced diameter neck portion of the bottle 110 in a smooth transversely curved annular surface 108.
