COMPOSITE MOISTUREPROOF PAPER BOARD.
Application filed July as, 1924. Serial No. 728,324.
To all whom it may concern:
Be it known that I, O'r'ro Knnss, a citizen of the United States, residing at Appleton,
county of Outagamie, State of Wisconsin,
5 have invented certain new and useful Improvements in Com osite Moistureproof Paper Board, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompany- 10 ing drawing, forming a part of this specification. I
. My present invention in its preferred embodiment has relation to the improvement of that class of moisture proof board intended for use in forming boxes, caddies,
cartons, and like containers intended for the packaging of products from which moisture is to be excluded or the moisture content of which products is to be retained. Features U of the invention, however, will be found 'capable of wider application.
The invention consists in the features of novelty herein described, illustrated in the accompanying drawing and particularly pointed out in theclaims at the end of this specification.
In the drawings, Figure 1 is a perspective viewof a moisture proof board embodying my invention. Figures 2, 3 and 4 are views 30 similar to Fig. 1 but showing several modifications of the invention. Figure 5 is a erspective view of a compound sheet ormedof three sheets of paper united by films af asphalt, similar to the upper compound sheet shown in Fig. 1.
In certain respects, the present invention is designed as an improvement upon that set forth in Patent No. 1,503,957 granted to my assignee August 5,1924.
In forming composite moisture proof board or compound pa er sheets by uniting together a plurality 0 sheets of 'paper by means of asphalt, it is found that there is a tendency of the residual oil, present in the asphalt to strike through the paper sheets and stain or discolor the surfaces thereof. My present invention overcomes thls objecsurfaces of. the composite board or comounjd pap er sheets, a sheet of sized paper hat will tend {to resist the passage there- ..jofthe residual oil present In the spha, t' 'and to-employ for one or more of the remaining sheets forming the board, a
tiongb'y employing for the outer or exposed sheet or sheets of unsized paper that will readily absorb the residual oils of the asphalt and so prevent the passage of such oils described.
It has heretofore been proposed to form boxes, caddies and like containers of dorm- I gated straw board surfaced with a top and bottom sheet of paper or board, the top and bottom surfacing sheets in some instances being made of waterproofmaterial, with a view to excluding moisture from the contents of the containers and with a view also to preventing access to the corrugated straw board of moisture which tends to impair its strength and hence the strength of the container as a whole. By the present invention, a box or container 'may be made which will more effectively serve not only to exclude the moisture from its contents, but also to guard against the weakening of the corrugated straw board by excluding moisture therefrom.
In the several figures of the drawing, the sheets of paper and the films-of asphalt are shown of'exaggerated thickness, for the purpose of better illustration, but it will be understood that these sheets of paper and films of asphalt will be referabl of the thicknesses and weights ereinaf r designated.
Referring to the form of the invention illustrated in Fig. 1, A designates a sheet of corrugated straw board of the weight and thickness commonly employed in the manufaoture of ,moisture proof board. To the upper and lower surfaces of this corrugated will vary somewhat according to the strength and thickness of the finished box orcontainer. In Fig. 1, theupper and lower composite board or compound paper sheets are shown each as formed of three sheets of paper designated respectively B, C and D, united by thin films of asphalt E and F. Preferably, the sheets B and D are of kraftpaper that may weigh about '65 pounds to the ream (480 sheets), this weight being based on a ream of sheets 24 x 36 inches. The 'center sheets C may be of paper weighing approximately from 10 to 253 pounds to the ream (of sheets 24 x 36 through the outer sheet D and staining or discolorin sheet O 0% unsized p'ifper that will readily absorb, such res'dual oils from "the asphalt. Preferably, also, the inner sheet,B will be formed of unsized paper in order to enable the silicate of soda or like cement that will be used to unite the sheet B to the corrugated straw board A to better penetrate the sheet B and thus effect a more secure and permanent, .bond between the corrugated board A and the sheet B. The outer sheets D are preferably made of ,sized paper which tends to prevent the penetration of the residual oils of the asphalt to the outer surface of such sheets.
When a box or container is made of the composite moisture proof board last described, it will be seen that the inner and outer composite sheets formed of paper and asphalt will serve effectively not only to prevent the" passage of moisture to or from the contents of the box or container, but will also serve to guard the corrugated straw board sheet A from becoming damp or soggy and so losing its strength.
In the form of the invention illustrated in. Fig. '2 of the drawing, the upper and lower composite sheets of paper and asphalt are shown as each comprising two sheets of paper 0 and D united by films of asphalt F, the inner sheets being cementedpreferably by silicate of sodato the corrugated sheet of straw board A. In this form of the invention, the sheets D are preferably of kraft paper weighing approxirnately to 90 pounds to the ream, while the films of asphalt F may weigh from 40 to 50 pounds to the ream. The inner sheets C are of unsized paper and thus more effectively serve not only to absorb the residual oils from the asphalt films F and pre- Vent such oils staining or discolor'ing the outer surface of the sheets D, but also serve to permit a more rapid and better penetration of the silicate of soda that is used in uniting the sheets 0 to the tips or crowns of the corrugated straw board 'A.
In Fig. 3 of the drawing, the corrugated sheet of straw board A. is shown as faced its surface, make-the central upon its opposite sides with composite moisture proof boards which are similar to the moisture proof board set forth in the hereiubefore mentioned Patent No. 1,503,957. That is to say, the moisture proof boards upon the opposite sides of the corrugated straw board A each comprises three sheets of paper designated B, C and D that are united together by thin films of asphalt E and F, and the sheets B are united by a suitable adhesive such as silicate of soda G to light stiffening paper boards H, these. boards H being united by silicate of soda or other suitable cement to the tips or crowns of the arches of the corrugated straw board A. The Weights of the individual plies or sheets making up the asphalted sheets of paper, as well as the weights of the film or films of asphalt used, will vary, depending upon the thickness and strength required in the finished container. Inthis form of the invention, however,..the sheet C will be of unsized paper, to prevent the passage of the residual oils from the asphalt through the outer sheets D, and the thin sheets of stiifened board H are preferably unsized so as to permit the better penetration thereinto of the silicate of soda 'or like adhesive which serves to unite the boards H to the crowns or tips of the corrugated straw board A.
In the form of the invention illustrated in Fig. 4 of the drawing, the corrugated straw board A-is shown as faced upon its inner surface with a sheet K of ordinary straw board, or if preferred, of a jute lined straw board, and upon its outer surface with a composite moisture proof board similar to that illustrated in Fig. 3- and above described. That isto say, the com-"" posite board upon the outer surface of the corrugated sheet A shown in Fig. 4;, consists of sheets of paper B, C and D united together by films of asphalt E and F, the innermost paper sheet B being united by a fihn of silicate of soda G to a light paper board H, which will be cemented by a suitable adhesive, such as silicate of soda, to to the crowns of the corrugations of the straw board A. In this form of the invention, as in that shown in Fig. 3, the sheet D Will-be of sized paper, the sheet C of ul1- sized paper, and the light cardboard sheet ll will be unsized, for the reasons already set forth.
In Fig. 5 of the drawing, I have shown a composite board or compound sheet similar to the board or sheet with which the corrugated straw board A illustrated in Fig. 1 is surfaced upon its opposite sides. A sheet thus formed may obviously be used for various purposes other than the covering of corrugated sheets, and being very thin' great many uses.
Having thus described my invention, what I claim as new and desire to secure by Let.- t-ers Patent is 1. A composite moisture-proof paper board or compound paper comprising a .plurality of sheets of paper united together by asphalt, the outer one of said sheets being .of sized paper and another of said sheets being of unsized paper adapted to absorb the residual oil from the asphalt and so prevent discoloration of the outer sheet.
2. A composite moisture-proof paper board or compound paper comprising at least three sheets of paper united together by thin films of asphalt, one at least of the outer sheets being of sized paper and the inner or central one of said sheets being unsized paper adapted to absorb the residual oil from the asphalt and so prevent dis-' board comprisin a sheet of corrugated board having ad esively connected to one Side thereof a composite paper board composed of at least three sheets of paper united together by films of asphalt, the sheets next to the corrugated board being of unsized paper and the outer sheet being of sized paper.
5. A composite moisture proof paper board comprising a sheet of corrugated board having adhesively connected to the opposite sides thereof a composite paper board or compound paper composed of a plurality of sheets of paper united together by films of asphalt, the sheets next to the corrugated board being of unsized paper.
6. A composite moisture proof paper board comprisin a sheet of corrugated board hiavin a hesively connected: to at least one si e thereof a composite paper board composed of a plurality of sheets of paper united together .by films of asphalt, and a sheet of light paper board adhesively connected to the innermost of said paper sheets, said light sheet of board being unsized and being cemented to said corrugated sheet.
