1'. 1.. TALIAFERRO METHOD OF FORMING LINERS FOR METAL CAPS FOR CONTAINERS Filed Nov. 13. 1924 Patented Feb. 22, 1927.
UNITED STATES PATENT OFFICE.
THOMAS L. TALIAFEBRO, OF CHICAGO, ILLINOIS.
METHOD or FORMING nnmns FOR marhncars non con'mnmns- Application m November 13,1924. f see-1a no. flaw The invention relates to new and improvements in the method of making liners for metal caps for ,containers- An object of the invention is to provide a method of making liners wherein the facing paper for the pulp board backing or'support is secured thereto by a layer of'wa'x "attached to the pulp board, adhering to a layer of wax attached to the facing paper,
and wherein said wax layers are so pressed together as to become a distinct layer, not
only uniting the facing paper to the pulpin a liner of the above type is also provided with adistinct layer of wax on the face thereof adjacent the content of. the con-' tamer, which wax layer is not only nonporous but moisture proof.
These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.
' coatings a In the drawings which show diagrammatically one embodiment of the inven-' tion-' a Figure 1 is a sectional view of a pulp board backing or support having acoating of wax thereon; Y
Fi 2 is a sectional view of a paper facing or "the pulp board support having a coating of wax on each face thereof, and
Fig. 3 shows the pulp board with its wax coating, and the facing paper with its wax plied, thereto, preparatory to the pressing o the parts thus assembled to cause the facing paper to adhere to said pulp board.
The method of forming liners is similar to a certain extent to that disclosed in myprior. Patent No. 1,47 6,115, granted December 4, 1923. In said prior patent, the facing paper is an oiled paper, and this is secured to the pulp board by means of a wax containing .a gum; While liners made after this method are perfectly satisfactory for mostpurposes, there are'times when it is desirable to have a liner which is non-porous and moisture proof. This is. not true oftheoiled paper. 'Furtherm'0re,,it is also desirable tohave a liner wherein the assembled parts include a layer which is capable of yielding toth'e irregularities in the glass so as to insure a very tight seal. The purpose 'of the present invention is to provide a.'
method offorming a liner which consists of pulp board, a paper facing and layers of wax, which layers of wax are preferably formed of paraffin, and in the finished article, said layers perform the double func-' tion of producing a cushion effect in the assemblcd parts of the liner, and also produc-. inga non-porous, moisture proof facing to which the content of the container are exposed.
To this end, I have provided a pulp'board 1 which is coated with hot wax so asto form a layer 2 which is of appreciable thickness.-
The wax will form a distinct layer by itself, which adheres to the outer face of the pul board and will not run into the pulp boar and saturate it. The paper facing 3 shown in Flgure 2, is provided with a layer of wax 4 on one side and a layer of wax 5 on the other side. These layers are formed, of
course, of the melted-wax, and this results in a distinct independent layer of waxon opposite sides of the facing paper. 7
The facing paper constructed as described above, is then laced on the'wax-coated surface of the pu p board as shown in Figure '3. While the wax is warm, as a result of the coating of the pulp board, or as a result .of apply ng heat to these assembled parts,
pressure is applied to the coated facing paper or the coated pulp board so as "to force these members toward each other. Thiswill cause the two 'wax layers between the pulp board and the facing paper, which contact, to strongly adhere, and in effect, form'a single layer of wax of sufiicint thickness to have a cushion-like effect when the liner is applied to acontainer. This will allow the liner to conform to any irregularities in the glass, and secureas a result, a tight seal. Furthermore, the layer 4 of paraffin on the outer face of the facing paper will likewise form a distinct layer on the surface of the paper, and this layer of wax is moisture proof and is nonporous, so that if the content of the container comes in contact with the liner, it will not work through the liner and cause the sealed package to leak."
In the carrying out of the method, the pulp board is preferably cut in a long strip, the
and these stri s are caused to adhere to each other, after w ich the liners are out from the assembled parts.
The article resulting from the method described above, is not claimed in this applicacation, but is described and claimed in my co-pending application Serial No. 749,663, filed November 13, 1924.
It is obvious that minor changes may be made in the method of assembling the parts, the essential features consisting in the utilizing of.the Wax to cause the facing paper to adhere to the pulp board. and the utilizing of the wax to form a cushion effect in the completed liner, and again in the utiliz ing of the fact that the layers of mm are non-porous and moisture proof.
Having thus described the invention, what I claim as new and desire to secure by Letters-Patent, is a The herein described method of forming liners for metal closures for containers comprising-"coating a layer-of pulp board with hot .Wax, coating a facing paper with hot wax on both sides thereof, applying saidwax coated facing paper to said wax coated face of the pulp board, and While the wax is warm. applying pressure to the pulp board and t'acin; paper to cause the contacting faces of wax to adhere.
In testimony whereof, I aflix my signature.
