IMPROVFEMENT IN PAPER BAGS.
Specification forming part'of Letters Patent No. I 76,548, dated April 25, 1876 application'filed r September 27, 1875.
To all whom it may concern 3 Be itknown that I, THOMAS PHILLIPS,'0f Akron, in the county of Summit andlState of Ohio, have invented a new and 'useful fiour and grocery bag, as an article of man ufacture and-I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, and which represents a flour-bag with a portion torn down to represent, by a darker surthe outer and inner surfaces of the ba g.
Manila paper, as at present used tor flour and other strong bags, is frequently made of two sheets run together in the paper-machine so as to form one thick sheet, and the pulp of both of these sheets has been hereto- In the making of my paper bag I prefer to use the bleached-pulp surface for the exterior of the bag a, which gives it the same saleable appearance as that of the bags now inus and made entirelyot' bleached stuff, and the inside of the bag has an unbleached-pulp surface, b, which is stronger and cheaper than the bleached pulp, so that at a reduced cost I produce a stronger paper bagthanhas been the other of similar pulp unbleached, or very little bleached, for the sake of economy of first cost, and for strength.
The pulp of which the paper composing the bag is made is not originally of different qualities 'or colors, as has been essayed by paper-makers, but is of the same quality-one part being changed in color by bleaching, the other pulp left in its natural color by being unbleached or slightly bleached. No coloring matter is put in the pulps.
What 1 claim as a new articleof manufacture is i The herein-described paper bag, having one surface of bleached pulp for the sake of merchantable appearance, and the other surface of unbleached or slightly-bleachedpulp, for the sake of cheapness and strength, as described and represented.
