Application filed March 12, 1926. Serial u 94,236;
This application is a continuation in' part of United States Ser. No. 22,759, filed April 13,1925. The invention forming the subject matter thereof relates to a composition 5 of matter and has for one of'its objects a convenient and portable form of a normally plastic medium used for toilet or medical purposes. By the term lastic medium throughout the following escription and 1 claims it is intended to represent any sort of an ointment, emollient, salve or a cleansing or healing instrumentalityof normally pasty, oily or greasy nature. Probably one of the most useful applications of the invention will be in connection with cold cream and as such it will be hereinafter described.
According to the invention a fibrous material is impregnated throughout with a nor mally plasticmedfium, the fibrous material serving as a vehicle therefor and the plastic medium being so retained within the material as to be liberated by the warmth of the skin when the composition of matter is rubbed thereover. Various types of fibrous 2 material may be availed of, such 'as fabric or tissue or crepe paper. More particularlythe invention comprises a sheet of crepe'paper of convenient size for handling with which cold cream is normally permanently combined. A peculiarity of cold cream, however,
is thetendency of some of its principal ingredients to volatilize upon exposure to the air. Consequently a'sheet of paper treated with cold cream in the obvious manner such as has been resorted to in the application of rouge to tissue is unavailing because of the time necessarily elapsing betweenithe manufacture of the toilet preparation and its use,
during which period the cold creamhas been 40 found to have entirely evaporated from the 9 ratus by which the method according to the pa er. 5 I I further object of the present invention is a method, of manufacturing fibrous material treated with a normally plastic medium,
such as cold cream, so as to assure the retention of the plastic medium in association with the material irrespective of the time element. To this end a plastic medium of a particular constituency and maintained at a predetermined temperature is distributed over the surface of a sheet of fibrous material simul-- taneously with the application of pressure to the sheet. Subsequently the sheets are treat ed in a seasoning process and further periods 0t pressureto produce a composition of mat "plurality of many terwhich maybe defined as a homogeneous article of fibrous material and a normally plastic medium, the plastic medium being incorporated within the very fibres of the'sheet in such manner as not to volatilize or escape e0 therefrom although the surface of the sheets may containpracticallymo oily matter which would render them inconvenient in handling. More particularly the method comprises applying the plastic medium evenly from a 55 solidified cake thereof over a sheet of fibrous mater al by an instrumentality to which the sheet s applied withthe simultaneous appli cation of pressure. Thereafter a plurality of such sheets may be stacked in bundles 'm sealed 111 'imperviousenvelopes and subjected to a seasoning process for a predetermined period dependent upon the quality of the fibrous material and the particular characterlStlCS of the plastic medium at the time of its application to the fibrous material. After the seasoning operation the bundles are again subjected to a predetermined pressure. again dependent upon the factors hereinbefore referred to. For the convenience of the users 0 the sheets may be incorporated in a pad or f booklet to be readilyremoved therefrom. To this end the bundles may be stitched and cut to the desired size to form pads.
The invention also resides in the instru- 35 mentality'by "which the method hereinbefore described may be carried out.
These and other objects of the invention and the means for their attainment will be more apparent from the following detailed description of preferred embodimentsthereof which are illustrated in the accompanying drawings and in which:
Figural is a view illustrating somewhat schematically one completed form of appastack of sheets of the composition of matter, 1
suitably stitched, and indicating by dot and dash lines how the stack may be cut into a leaved booklets.
Figure 3 isa view in perspective showing one of the booklets out from a stack'and in ready for use.
In the following description the 7 terms tissue or crepe paper and cold cream will be used as illustrations, respectively, of types offibrous materialand a normally plastic me- I I contact therewithor rubbedthereover.
It has been found that the ess ential'ingredients of some cold' creams manufactured-Q dium with which the, same is impregnated but it is to be understood that these terms. are used by way of illustration only and the invention in its broadest aspects contemplates its application to a. variety of products having the characteristics of the material named.
If coldcream were applied to a sheet of fibrous material, such as tissue paper, in the ordinary manner, even though the paper could be said to be saturated with the same at the time of. manufacture it would be found that with the lapse of time all of the cold cream had evaporated leaving the paper dry and substantially free from cream, and this even though thetreated tissue were confined a hermetically sealed envelope." it has been found, however, that the evaporation and loss of the cream may be avoided" when a method of manufacture is adopted which will force or drive the cold cream into-the very fibre of the tissue to make, ineitect, a Homogeneous article of fibrous material and cream.' Then even though I the cream on the surface of the paper evaporates, that entrained, within the fibre, and perhaps also in the interstices of the fibres,"may be liberatedby'the heat of the skin when the. tissue. is brought into according to certain formulae volatilize so readily as to be impractical fog; thepurppse at hand while other creams made according to other formulae are so liquid or so easily liiiuefiable as to be'equally inapplicablej-The co d cream capable of be forced into the fibre and retained therein it is believed must be composed ofidgredientsnotreadily volatilized and of suflicien't solidity and 'bodyto.
force its way into the fibre under pressure."
This cream when maintained at moderatelylow temperature is substantially solid andin the process of manufacture-of the composi tion of matter is used in the form of a brick-1 The cream maybe incorporated with various gradesof paper and the formula; and consistency of the cream selected is dependent to some extent on the stock to be treated. A heavier paper necessitates the application of more creamof-a stifi'er constituency and may-be found advantageous to apply another sheet of similar tissue to the one already treated with cold. cream and this sheet is juxtaposed to thefirst sheet against that side evaporates. The enveloped stacks are placed so in a chamber or seasoning room and maintained at a predetermined temperature between "40. and 60? F. dependent to some extent uponthe paper and cream and prossures used. .Ithas beenfound that a sea- 5 soning temperatureof substantially 50 will give excellent results. Apparently during the seasoningoperation the cream works its way into the fibres of the tissue and the cream sets therein to form what is in effect a homogeneous structure. After the seasoning the bundles, still wrapped in impervious covers are subjected to great and extended pressure at vwhich time the cream is wholly driven into the fibres-ofthe material while substantially none is left Ion-the surface. 'By

After the bundles are 'ressed it will be fbun'd desirable toform boo ets of the cold cream tissuefrom them. The'bundles are therefore stitched at cutrup into "ooklets ready for the market.
fibrous material a is illustrated as formed in a ressurerollsib. One of the rolls, say 0,
requires a greater application of pressure in orins' one of a train oflc'old cream applying the process. With a non-volatilized cream as described above and retained in brick form at a temperature of from 40to 50 F. a
paper stock of about fifteen is used.
In the manufacture, the solidified cold cream is' applied to the paper simultaneously with the application of pressure thereto, a suitable instrumentality being availed of to insure the even application of the cream in the proper quantities. In some situations as under certain conditions of the cream due to atmospheric or temperature conditions it pounds base rolls 0 e by. which cold cream is taken from, esurfaceof abrick m, of cold cream and applied to-one surface of the sheet simul- Ohe' form of apparatus by which the 'method-ofmanufacture may be carried out isillustrated in- Figure 1. There the sheet of ipred'etermined pointsandthen i roll a from-which it is led between .a pair of taneously yVith-theressing operation, the roll 0, serving to app y. the proper .amountof I cream evenly over the surface of the sheet, In order that-thebrick of cream may be main- 4 tained at the proper stiffness itstemperature" is controlled'by refrigerating: coils e,dispos ed a about the pan. f, wit inaeaSing-adapted to be -pres sed;upwardly against the roll a, by means of the springs'g. Inorder to further control the quantity-10f. cream in itsapplicai v tion the paper, the central roll. d is mamas ingly maintained againstthe outer rolls by ad'ustable spring pressed bearings d.
rom the rolls b, c the treated sheet is conducted to cutting devices It, which sever the sheet coming from the roll into a plurality of rectangular sheets a which are then stacked into a bundle a If desired, depending to a reat' extent onthe characteristics of the librous material andthe constituency of the cream, a second untreated sheet of fibrous material may be annexed to the treated sheet on that side to which the cream has been applied. To this end a sheet i may be conducted from a roll 11 and pressed into contact with the sheet a, by pressure rolls 7', 7c. The pressure of the rolls may be regulated by the spring pressed bearing 9" on roll j; In this instance, the rectangular sheets (1 comprise two layers as will be understood. The undles are then subjected to a seasoning process,
During this seasoningthe edges of the sheets have a tendency to dry out. To obviate this the bundles a, are enclosed in animpervious envelope Z, The wrapping, of course, may be done by hand but in the illustrated embodiment the stacks are shown as formed on. a traveling belt-n periodically movable to convey, by the stops m, a bundle within the V envelope Z and then convey the wrapped bundle onto a conveyor n upon which the bundles are conducted during a seasoning operation Within a chamber 11/ wherein the atmospheric, temperature and time conditions 'areregulated according to the characteristics of the sheets at the commencement of the seasoning.
At the end of the seasoning treatment the bundles are delivered onto a belt 0 which conducts them to a press p where they are sub- 'ected to a pressure dependent upon the numr of sheets making up a bundle and the characteristics thereof; After the pressing operation the bundles are removed from the envelope and stitched as indicated at a and then out along the linesa into a plurality of booklets a as'shown in Figure 3. g
It will thus be seen that a convenient; in?
. strumentality has-been provided incorporate ing plastic medium in a vehicle which can be readily carried about the person, for instance,
foruse at times when the medium in-the" usual receptacles cannot be conveniently carried or used.. This instrumentality isbest defined as a homogeneous. articleoof a plastic medium and fibrous-material and with it the plastic medium maybe transferred to the skin the warmth ofthe slffn being suflicient to liberate the plastic medium.
While the invention has been described as the product of and/or a method by=which cold cream may be incorporated in a sheet of .tissue paper it is to be understood that the invention in its broadest aspects is not limited to such but is equally applicable to any'plastic medium, such as ointment .or other grease like paste carried with a fibrous material,
such as, paper, fabric or equivalent substances for convenience in handling and use. What I claim is:
1. The method of manufacturing a homogeneous article of paper and a cold cream which consists in evenly distributing the cold cream from a substantially solidified brick of predetermined characteristics maintained at a predetermined temperature over one surface of a sheet offibrous material simultaneously with the application of pressure, and in a film of such thinness it may be held prac tically absorbed therein so that no substantial cream appears as such free on the surface of the paper, seasoning the sheet to effect substantially perfect assimilation of the cream by the sheet, and pressing it.
2. The method of manufacturing a homogeneous article of fibrous material and a plastic-medium which consists in evenly distributing the medium from a substantially solidilied brickof predetermined characteristics such thinness has been applied that it isheld' practically absorbed therein and no cream. appears'as such free on the surface of the paper and which has beensubjected to a seasoning operation-tor effect substantially perfect assimilation of the cream by the paper..
4; The method of manufacturing a toilet [preparation comprising applying cold cream to a-sheet of paper -1n a layer of suchthinness that when applied to the paper it may be held practically absorbed therein so that substantially no cream appears as such free upon the'surface of the'paper, and subjecting the article so formedto a seasoning to effect perfeet assimilation of' the cre'am'by the paper.- ;5.. The method of-manufacturin'g a toilet preparation comprising applying cold" cream. to a sheet of paper in a layer of film of such thinness thatwhen applied tothe paper it may be held practically'absorbed therein so that substantially no cream appears as ,such free upon the surface of the paper, subjecting the article so formed to "a seasoning to effect perfect-assimilation of the cream by the paper,-and. thereafter subjecting thearticl'e-so-for'med to pressure.
