Definitions

  • This invention relates to composite material for use in the manufacture of containers and more particularly to a composite material especially adapted to the purpose, of providing a liner for bottle caps and the covers of containers in general.
  • composition cork inserts have been employed, such'inserts comprising com 'minuted cork and a suitable binder
  • Such 5 composition inserts, or liners are more dense and uniform than such liners made from the natural product but they are still unsatisfactory for many purposes because of the fact that thebinder of the composition is attacked by many solvents and this results in disin: tegration of the material which is supposed to form the seal for the container.
  • composition cork and other fibrous resilient materials may be used in accomplishing the objects of my invention but these materials are not used alone, or merely protected by .a
  • I provide some preferably resilient fibrous material, such as cork, composition cork, pulp board, news board, or gray felt and to this material I apply protective layers of a waterproof adhesive and an insoluble varnish.
  • the adhesive and varnish may be carried by a suitable medium, such as cellulose material in sheet form, for example, paper, or the like.
  • cellulose material in sheet form, for example, paper, or the like.
  • I have found that paper is quite satisfactory as a carrying medium and I prefer to employ thoroughly sized paper Whichhas been thoroughly calendered to provide hard surfaces.
  • I apply in any suitable manner a film of what I call insoluble varnish.
  • insoluble varnish is 'eant a varnish which is insoluble, or inert such solvents as alcohol, acetic acid, citric acid and carbonic acid.
  • varnish although insoluble in and impervious to alcohol and acids of the character described, nevertheless absorbs some moisture and permits some moisture to pass through a film of this varnish. Accordingly, I employ a film of waterproof adhesive and this is employed in such a manner that it is protected front the action of alcohol and other solvents of the character indicated above which would otherwise destroy the adhesive.
  • I may apply to'one silr face of the. sheet of paper, or the like, a film of insoluble varnish.
  • a film of waterproof adhesiye such as gutta-per'cha, or sir'nilar rubber-'llke material.
  • This adhesive may be used as a means I i a.
  • the sheet of paper, or the like for bonding the sheet of paper, or the like, to a base material, preferably resilient in character, such as cork,pulp board or felt.
  • This composite material may be cut intosuitable form for application to bottle caps, jar covers and the like, or,'if desired, the material'may in a sense be assembled within the container cover.
  • the paper may be coated, or otherwise provided with films of varnish and adhesive.
  • the resilient material may be inserted in the container cover and thereafter the varnished and adhesive coated paper may be applied to the fibrous material within the container cover or cap.
  • a varnish which comprises a resin which is resistant to alcohol, acetic acid, carbonic acid and the like and an oilwhich is resistant to these materials.
  • the varnished surterial and together form a complete seal for the container which is impervious to moisture and inert to the action of such ingredi ents as may constitute the contents of the container.
  • the adhesive is protected by the varnish and, while the varnish alone is incapaable of preventing the escape of moisture, yet this function is performed in a satisfactory mannerby the adhesive which remains intact because of the presence of the protective film of varnish.
  • my invention is particularly suitable for use in the manufacture of containers for beverages, food products and pharmaceutical preparations, many of which contain alcohol, or acids of the character indicated above, which would attack and destroy the ordinary varnish films heretofore proposed as a means for sealing the surface of cork, or other inserts used in container covers.
  • FIG. 1 is a plan view of a strip of composite material embodying my invention
  • Fig. 2 is an enlarged planview of a disc cut from the strip illustrated in Fig. 1;
  • Fig. 3 is an enlarged elevation of the disc shown in Fig. 2 and Fig. 4 is a greatly enlarged fragmentary section view of a portion of the discillustrated in Figs. 2 and 3.
  • a strip of composite material embodyin my invention comprising a base ayer of material 1 preferably resilient in character and a superimposed composite layer 2 adhering to the-base layer.
  • the composite material is shown in strip form from which blanks may be out in any desired shape to fit bottle caps, jar covers and the like, or for other purposes.
  • Fig. 2 shows in enlarged form a circular disc cut from the strip illustrated in Fig. 1. From this enlargedvlew it ap ears that the composite layer 2 supported y the base 1 comprises a carryin medium 3 in the form of a sheet of paper aving on its upper surface a film 4; of insoluble varnish and on its lower surface a fihn of waterproof adhesive 5.
  • the base material 1 comes in contact with the inside of the cap or cover and the varnished film is exposed to thecontents of the container.
  • the film of varnish is highl resistant to and impervious to solvents, sucfi as alcohol, aceticacid, citric acid and carbonic acid, or in other words the varnished film may be saidto be insoluble.
  • the adhesive 5 while not necessarily insoluble in alcohol and acids of the character described, is
  • the layer of paper, or t e like, disposed between the films of varnish and adhesive serves, not only as a carrier for these films, but also as a means for strengthening and reinforcing the composite material to prevent accidental injury to the underlying adhesive film.
  • the combination of varnish and adhesive films according to this invention entirely prevents from the container.
  • the layer of paper, or other cellulose material, illustrated at 3 in the figures of the accompanying drawing is preferably hard surfaced. Where I- employ paper I prefer.-
  • the adhesive material 5 is preferably a" composition may be altered accordinglly) to provide an adhesive which is not unduly r Y used herein is intended to describe an adhesive material composed entirely, or only in part, of gutta-percha for various ingredients may be combined with the gutta-percha to improve its characteristics for certain purposes.
  • Gutta-percha in strip form may be applied to the paper 3 in any suitable manner, or the gutta-percha adhesivemay be dissolved in a suitable solvent and applied to the paper 3 in liquid form.
  • the product is to be used under conditions such that relatively high atmospheric temperatures prevail it is desirable to incorporate withthe gutta-percha materials which have a tendency to harden the same and prevent it from melting or softening at elevated atmospheric temperatures.
  • low temperatures prevail the gutta-percha ittle. at the prevailing low temperatures.
  • Gutta-percha is especially suitable for accomplishing the objects of my invention for it is waterproof and when combined with a" film of varnish as contemplated by my invention a composite material impervious to moisture is formed.
  • the gutta-percha adhesive may be first dissolved in an appropriate volatile solvent, such as highly refined gaso-' line, naphtha, toluene, benzene .or xylene.
  • an appropriate volatile solvent such as highly refined gaso-' line, naphtha, toluene, benzene .or xylene.
  • the solution may be heated until the mass thickens and it may be applied in the thickened state to the back of paper previously varnished and the remaining volatile solvent permitted to evaporate.
  • Various or resins are available for thisvpurpo'se including certain natural gums and at least one synthetic gum. Of the natural gums Zanzibar, Madagascar, and esterized manila gums give the best results. All of these natural gums which are insoluble in alcohol, and black damar, elastica (dry rubber resin) and certain grades 01- copal, fuse with di fliculty in the oils. Esterized manila however fuses more readily than the others.
  • Cumar gum (manufactured by the Barrett Companyis soluble in the hot oils of the varnish wit out. any preparatory treatment. Cumar gum may be compounded largely with certain of the oils which are resistant to alcohol, such for example as China wood oil, and it has been .found that with such a combination it is possible to add small amounts of oil, such as linseed oil, which is soluble in alcohol, and this without destroying the alcohol resisting properties of the varnish.
  • any volatile thinner in which the constituents of the varnish are soluble may be employed.
  • a hydrocarbonthinner such as high test kerosene, is suitable.
  • Various oils may be used to dissolve the cumar gum.
  • the following example is given as a representative varnish composition which may be regarded as insoluble in alcohol and in acids of the character indicated above :150-pounds cumar gum, 50 gallons China wood oil, 5 gallons linseed oil, 5 gal lons perilla oil, 18 pounds precipitated manganese resinate, 10 pounds cobalt linolate,
  • This varnish may be thinned down hot with high test kerosene, or any other appropriate volatile solvent.
  • This example is used merely as an illustration of one type of varnish which is suitable for carrying out my 1nvent1on.
  • Such a varnish successfully withstands the corrosive or solvent action of chemicals such as alcohol, acetice acid and citric acid or the like customarily encountered in beverages, food products, pharmaceutical preparations and cosmetics.
  • the varnish After the varnish is applied to the paper it is preferably baked to harden the varnish filmand increase its resistance to the action of chemicals. It is quite satisfactory to bake the varnished paper at a temperature of-aptrial, and a film of waterproof adhesive bonding said resilient material to the other proximately 300 F. for about an hour.
  • the adhesive coating may be applied to the paper after the baking operation has been completed.
  • a composite material of the character described comprising a layer of sheet material, an insoluble film of varnish adhering to one surface of said layer of sheet material, a layer of resilient material, and a waterproof adhesive bonding said resilient material to the other surface of said layer of sheet material, whereby the adhesive is protected from the action of solvents by the film of varnish and a composite material impervious to moisture is formed.
