Definitions

  • Bottle caps of the type to which my lnvention relates have heretofore been extensively used for sealing bottles containing mmeral waters and other iuids having al deleterious action upon the cushion disk within the cap, Aparticularly when this disk is made of composition cork.
  • theh facing center disk has been made of tin foil cemented or 'otherwise attached directly to the cushion disk, or secured thereto by means of a fibrous backing having applied thereto a dry adhesive made tacky by means of a thin film of moisture applied to the cushion disk.
  • the object of my present invention is to provide a bottle cap having a protecting center disk secured in position by a fusible medium de void of moisture, and thus avoid any possibility of slippage of the disk while pressing it disk in application tied.
  • the medium used for securing the facin place is of itself water insoluble an acld resisting and, being fusible at low temperatures, will vform a very thin coating between the facing disk andthe cork so as to preclude the possibility, in the event of imperfections inthe facin disk, of the cork being attacked bythe fiui contents of a bottle.
  • the cementing medium may be readily fibrous disk ⁇ and thereby minimize the danger handled, is not affected by ordinary changes ,of temperature or atmospheric conditions,
  • the facing disk may be readily cut to size simultaneouslywith the cutting of the facing disk so as to secure a bonding stratum coeextensive with the area of the facing disk, and may be quick- 1y fused to secure the desired bonding action between the facing diskand the cushion disk.
  • vcushion disk within said shell, a facin' disk of water repellent, gas impervious fibrous material, such ⁇ as a relatively hard, highgloss' or water-finishpaper provided with a coating of' resistant varnish, said disk being of smaller .diameter than, and concentric with, said cushion disk, and a thin stratum of a water insoluble, fusible, cementitious material, such as gutta percha co-extensive 1n area with said facing disk, between said facing disk and said cushion disk; and in such other novel characterlstics as are hereinafter set forth and described, and to the method of making said. caps, all as hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.
  • Figure 1 1s a bottom plan view upon an enlarged scale of a bottle cap embodying the invention.
  • Figure 2 is a section on the line 2-2 of Fig. 1.
  • Figure 3 is a vertical section illustrating the 'first stage of applying the center disk to the cushion disk.
  • Figure 4 is a similar view illustratlng the Figure 5 is a viewillustrating a stage intermediate those illustrated in Figs. 1 and 2,
  • a bottle cap embodying the invention consists of the usual metallic shell a having a fluted skirt b. Secured within this shell is a I lcushion disk c, which may be either of natural,
  • composition cork is more extensively used than natural cork
  • the lip of the bottle Will be positioned between the facing disk and the skirt b, the contacting area being such as to bring the facing disk to a point at the inner edge of such contacting area.
  • the dimculty of applying V a' center spot ofpa. r to the cushion disk presents roblems a together different from the use o a facing disk coextensive, with the cushion disk; as for example the facing disclosed in my Patent No.11,656',614, granted June 17,11928.
  • a facing which completely covers the cushion disk may be readily united .adhesivel to the sheet or blank fromwhichv the cushion disk ⁇ is stamped, ⁇ or in other words, the facing sheet and cushion sheet a're united adhesively, and the laminated disks unched therefrom. f But in applying a" ormed center.
  • the exposed edge of the paper spot is of an area which cannot be protected by a facing, such as foil or varn'ish, since the spot is punched from I sheets.
  • This objection I have overcome by ausing a combination consisting of paper of f the character described and a liquid and gas resistant fusible adhesive..
  • this new cap is resistant to acids and alkalies and', therefore, useful in connection with liquids with which a foil spot cannot be employed, and that it is at the same time substantially less expensive than a foil spot cap. Moreover, it does not present the mechanical diiiiculties'which are present in applying a foil center spot.
  • the hard, tough paper serves as an excellent carrier for the varnish film as Well as for the gutta percha and insures coextensive varnish'and gutta percha films.
  • the gutta percha serves not only as a medium for uniting the paper and varnish films to the cushion layer, but constitutes an acid and gas-resistant, waterinsoluble, backing layer, thereby preventing m0isture, acids or gases which penetrate the varnish film or paper from attacking the cushion layer.
  • a hard paper having a Water-finish or high-gloss permitsthe use of even films of varnish and gutta percha, since the paper does not'absorb either the fused gatta percha or the varnish to any appreciab e extent. Consequently, it
  • the center disk d is composed of a glazed hard paper, such as is generally known as express paper, sulphite paper or bleached kraftpaper having' a water-finish, i. e., high-gloss finish.
  • a glazed hard paper such as is generally known as express paper, sulphite paper or bleached kraftpaper having' a water-finish, i. e., high-gloss finish.
  • Such papers are, of themselves, independently of the finish, fairly non-absorbent, and when required for pasting purposes, are usually provided with a dry gummed surface. The process of producing 4such gummed paper results in a curl in the paper.
  • a cap embodying theinvention lends itself to rapid roduction methods, which will now be descri d. l
  • the centerdisk d is compl tely assembled in relation to the shell a.
  • the caps, completely assembled, may be rapidly fed in relation to cutting dies g. and,
  • a very small quantity of wax such as parain or ceresin wax or wax-compounds, may be delivered upon said disks-within the shell a following the application of the disk d to the disco, and prior to the application of heat and pressure through the medium of the car Arier z' and plunger j.
  • heat and pressure will spread a drop of wax in a ver thin lfilm about 'the entire exposed face'of t e two disks, theraw edge of the diskd .also being coated with this Wax.
  • This thickness of thedisc d will be a proximately ive-thousandths of an linc y while the thickness of the binding stratum'e, in the ultimate product, will be relativelyv less than the thickness of the gutta-percha tissue, or a mere fraction of a thousandth of an inch.
  • the wax surface stratum will also be but a mere Afraction of a thousandth of an inch, and is not perceptible to the eye, although sensible to the touch.
  • the glazed face of thedisk d does not require, a wax surfacing, and, so far as I have vbeen able to determine, most of the wax is . ⁇ expressed from this surface and forced from the disk to the exposed area of the cushion disk c.
  • the glazed surface upon the strip d con-v sists of a waterproof compound consisting of resin, China-wood oil and a drier, and con'- taining a plasticizer.
  • a bottle closure comprising a metallic shell, a cushion disk in said shell, a facing disk of yhard paperhaving a varnished outer surface, said disk being of smaller diameter than and concentric with said cushion disk, and a stratum of heat-fusible,acid-resistant and water insoluble adhesive material cextensive in area with the facin disk between the latter and the cushion dis and uniting the two disks.
