Definitions

  • closure caps having crimped edges to be deformed to grip a bead on the bottle and known as crown caps have been used in the sealing of bottles containing charged liquids.
  • crown caps have excelled so in holding against pressures up to 120 p.s.i. that their use has been almost exclusive in this field despite the fact that they can be removed only with a prying tool and are deformed thereby so as not to provide an effective reseal.
  • An effective reclosure seal undoubtedly can be made of bulky or expensive materials or in intricate designs not suitable for the bottling industry where package costs must be competitive. The need for an economical package capable of withstanding the pressures of charged liquids and providing an effective reseal has persisted for many years.
  • an object of this invention to provide for the sealing and recl-osing of charged liquid packages. More particularly, it is concerned with providing an economical package for this purpose.
  • the specific object of the invention is to provide an economical containerclosure combination suitable for modern high speed packaging operations and affording a pressure seal and effective reclosure.
  • FIG. 1 is a vertical sectional view of the closure blank used in the combination
  • FIG. 2 is a partial vertical sectional view on a larger scale showing how the closure blank is reformed on a contanier designed for our combination, the form of the marginal portion of the closure and liner prior to deformation being shown in dotted lines;
  • FIG. 3 is a fragmentary sectional elevation view showing the finished package.
  • the cap blank 9 is drawn from a sheet 0.008 to 0.0095 inch thick of deformable aluminum base alloy in the extra hard temper designated H19.
  • the term aluminum base alloy means an alloy containing at least fifty (50) percent by weight of aluminum.
  • the aluminum base alloy used to make the closure blank contains aluminum and between 0.3 and 1.5 percent manganese, between 0.2 and 0.8 percent magnesium and other metals not to exceed percentages of silicon 0.6, iron 0.7, copper 0.4, chromium 0.25, zinc 0.4, titanium 0.1, and in any other metal 0.05 and the total of other metals 0.15. This alloy is preferred as it is readily deformable and has good strength characteristics in the H19 temper.
  • the drawing operation provides a top panel 10 and a depending cylindrical skirt 11, and the skirt is knurled at 12.
  • a liner 13 preferably of an odorless and tasteless elastomeric material, such as for examle poly vinyl chloride.
  • the liner 13 should be retained in proper position by adhering it to the top panel, and liners made of poly vinyl chloride should be 0.028 inch thick, plus or minus 0.003 inch.
  • the drawings show the liner 13 as a disk, however, a ring type liner would also be satisfactory.
  • the closure receiving finish of the container 20 includes top sealing surface 21, a reduced annular portion or recess adjacent thereto presenting a side sealing surface 22, a radially outwardly extending shoulder 23 below the side sealing suface and closure retaining means, such as screw threads 24, below the shoulder.
  • the pressure block 30 used in applying the closure to the container 20 has a recess 31 and a shoulder 32. With this design, the pressure block deforms the marginal portion of the closure and liner from the horizontal plane positions shown in dotted lines to that shown in full lines in FIG. 2, while applying top pressure, to assure sealing contact over the top and side sealing surfaces 21 and 22.
  • a thread roller 33 Cooperating with the pressure block 30, in that it acts while the block retains the closure under pressure, is a thread roller 33 which deforms the skirt 11 into conformity with the threads 24.
  • the closure skirt 11 includes a band 14 connected to the remainder of the skirt by a number of frangible bridges 15, and the container has a downwardly facing, inwardly directed, shoulder 25.
  • the margin of the band 14 is turned under this shoulder by means of a roller 34 acting simultaneously with the thread rolling operation.
  • the band also acts to retain the liner compression and sealing efficiency.
  • the right angle bending about the top and side sealing surfaces provides a margin without irregularities and so provides uniform length of skirt in the finished closure.
  • the design provides a reduced top panel diameter after application for any given diameter of thread formation.
  • the effect of this is to reduce bulging of the top panel by internal pressure, because the fulcrum of such bulging is on a line nearer to the center of the top panel. This results in a lesser loss of liner compression that otherwise would be caused by internal pressure.
  • the knurled portion 12 of the skirt assumes a slight upward inwardly directed taper. From this, tension in the shoulder 16 formed by the pressure block 30 tends to collapse the unsupported portion of the skirt but this tendency to collapse is resisted by the knurling. It follows that residual tension in the shoulder 16 aids in maintaining liner compression on the top sealing surface 21.
  • a container-closure combination for packaging materials which develop pressures substantially above atmospheric pressures comprising,
  • a container having an upper open end presenting a top sealing surface and an exterior finish including an annular recess extending downwardly from and adjacent to the open end and presenting a side cylindrical sealing surface, an annular outwardly extending shoulder below said side sealing surface, a screw thread formation below said shoulder, and an annular inwardly directed shoulder below said thread formation, and
  • a closure having a metal thickness between 0.008 and 0.0095 inch composed of an aluminum base alloy in the extra hard temper, said closure including a top panel and depending skirt, the upper portion of the skirt being of lesser diameter than the portion immediately therebelow, a portion of the skirt below the lesser diameter portion conforming to the thread formation on the container and a band integrally connected with the skirt by frangible bridges around the skirt, said band having a crimped margin turned inwardly under said inwardly directed container shoulder, and
  • a sealing liner of resilient deformable material underlying the top panel of the closure and bearing on the top sealing surface contact with the cylindrical side sealing surface on the container by said lesser diameter portion of the closure skirt
