This invention has relation tothe pro-' vision of-sheet paper or other fibrous material in the form of or for the formation of container mouth hood covers, and particularly involves a paper or other fibrous material disk either in hood cap form or in fiat form, as an article of manufacture, that possesses certain peculiar characteristics, whereby such disk is adapted, when softened by heat, to be 'molded and'secured'by contraction under the exterior rim of a container mouth or into exterior depressions or irregularities of the container mouth or neck, to become stiff or approximately rigid when cool and to maintain-its position covering and lockedon the container by reason of the stiffness or approximate ri the contracted part of ,the set disk thus shaped on the container, without added or separate bands, ties or other fastening means; and the objects and nature of the invention will be readily understood b those skilled in the art in the light of the following explanations of the accompanying drawings that illustrate what I now believe to be the preferred mechanical ex.
pressions or embodiments of my invention from among other forms, positions, constructions, Within the spirit and scope of my invention. -An' objectof the invention is to provide an inexpensive effective sheet paper material hood cap or hood cap disk for containsubstances, comers, particularly for glass bottles and the like, carrying a binder that is of high-melting-point quick-setting, and normally-hard, and that imparts to the portion or portions of the hood cap carrying the same sufiicient strength for hood cap securing purposes and the characteristic of being capable of stripping or peelin from lass surfaces without leaving an objectionable glass fouling deposit such as results from attempts to employ paraflin alone to bind hood caps on glass bottles, without noting the softness, low melting point, low strength, and slow setting properties of such paraflin.
With this and other objects in view, my invention consists in hood cap sheet paper or other fibrous material possessingcertain' characteristics as more fully and particulargidity of 4 and adaptations A CORPORATION 01' YORK; f AND OTHER CONTAINERS. 1

I .7

Fig. 4 shows a bottle mouth andthe sheet disk shaped thereon to .form a hood cap or y cover self secured thereon.
diagrammatically illus Fig. 5 shows in side elevatiompaper or":
other sheet fibrous material hood form for form to container thereon, when softtion, and in skirted orfflared application in such mouths for securing terior container mouth rim.
In carrying out my invention, flat sheet skirted or flanged cover or hood cap, such as 3, that will exteriorly cover. and protectthe mouth portion of a container, such-as.
sued by heat, by contraction under the ex,
portion thereof, or otherwise to lock the cap on the bottle mouth by contraction into a depression or under a projection at the exterior of the neck.
It is acharacteristic of my invention that by embodying in the disk certain substances or their equivalents, I can form each disk of a single ply or layer of thin inexpensive fibrous material such as certain commercialapers or sO-called. pulp boards, without buil ing up special materiallayer by'la'yer or otherwise constructing the same in lamibleached refined Montan wax,
and parafiin oil,
impregnated with the wax.
,drain or otherwise dewax the paper surfaces a sheet of comparatively thin flexible commercial paper of'one thickness, when carrying anyone or morelof several-substances such as waxes that meet.
certain requirements, distributed throughout a sheet of such paper, or if only at the portions thereof that-are to perform secur ngor holding functions, willpossess certain characteristics necessary for hood cap purposes, under my invention; For instance, sheet fibrous material suitable for hood cap purposes, impregnated in whole or in. part with any one of certain synthetic waxes or nsoluble soaps, or with c-arnauba wax,'or -w1th or with shellac or with a composition of candelilla wax or with the commercial product known as Smith and hliehols vegetable wax, possesses characterist cs within the spirit and scope of myinvention.
I find that sheet paper material that embodies anv one or more of such substances remains stlfl' or set at the portions treated therewith, at atmospheric or climatic temperatures, and becomes. soft, pliable or moldable when heated to the necessary temperatures, is perfectly sanitary for use on or n connection with food products, is approx mately insoluble in water, is without Ol)]C tionable odor when cool or set, does not attract vermm or insects, is non-poisonous,
wax,
does not foul or objectionably adhere to glass or to the surfaces of the cap forming or applying head, and is not seriously objectionable in color.
The single ply or thin paper material disks can be treated with one or more of the waxes and insoluble soaps hereinbefore mentioned, by dipping in the wax while such wax is in the melted state, or in any other suitable manner. I prefer to impregnate the paper or sheet fibrous material with the molten wax and drain or otherwise remove surplus wax from the surface of the paper.-
As at present advised by experience, I wish to avoid excess exterior coatings of the wax on the. surfaces of the paper but wish the wax to fill or impregnate the body or interior of the paper, as the excess surface coatings are but surplusage and when the paper is heated to the wax melting point such sur plus surface coatings are liable to flow therefrom to adjacent or contacting objects. The wax is reduced to the melted state by heat, and when the liquid wax is applied to the paper sheet, or the paper sheet is completely or partially dipped or immersed in the wax, the wax is absorbed or otherwise taken up by the paper which then becomes internally I preferably to remove exterior or surface wax from the paper to'avoid excess exterior coatings of wax or waxsurplusage, while retaining sulfa cient wax within the body of 'thepaper and on the surface -thereof,for thejpurposes of my invention, Any suitable method Jcan'be "followedto'flremove exterior surplus Wax from the paper; The paper di and thereby by the disk 1, of Fig. 2.

The hood cap thus formed on the bottle mouth from the flat disk 1 when softened by heat, has a usually flat central portion 5 (whereon usually appear certain exposed display indicia, legends or advertising) and an annular depending skirt orflange 0 that quickly sets and is contracted at d under the exterior rim of the bottle mouth, and that becomes stifl or more or less rigid at climatic oratmospheric temperatures to secure or look the hood cap on the bottle mouth. The skirt or .flange thus provides the self securing'or locking por- I tion d of the hood cover, and it is essential that at least the portion of the paper disk 1 that is toform this part d of the hood cap, be impregnated with one or more of the waxes hereinbefore mentioned or the equivalent thereof.
The flat paper disks will be usually placed on the market properly impregnated with one or more of the waxes or equivalent substances, usually with the central portions of the disks imprinted or hearing the desired display matter. I
The bottlers will purchase these flat treated paper disks, and will be equipped with proper implements or machines for molding the fiat disks, when softened by heat, directly on the bottle mouths to form the hood caps thereon, insuch manner that said caps remain locked or secured onthe bottle mouths by the stiff or' rigid contracted flanges of the caps. The softened portions of the caps, quickly 'cool to atmospheric temperatures and quickly become set and rigid so that removal of the cap preferably re-' quires rupture or tearing of the flange there.
tion of an insect. Montan wax is a mineral product produced in Europe but for the purposes of my invention it is necessary to use the refined or bleached commercial product of this wax, either alone or mixed with a small proportion of paraflin oil, or other neutral wax, grease or oil, suitable for the purpose.
Carnauba, candelilla, and Smith and N ichols, are vegetable waxes and. for my purhowever,

neck and cap forming head. The paraflin oil, or its equivalent, corrects this difficulty and renders the wax neutral as-an adhesive for glass and metal when impregnating the paper disk;
All of these waxes even whenmixed with paraffin oil in proper proportion, are homo geneous masses or solids at atmospheric or climatic temperatures and paper 1mpregnated therewith remains sufficiently stifi', set or rigid at such temperatures for the pur-' poses of myinvention, and becomes soft or. moldable when heated approximately to the melting points of the waxes which is approximately between 150 and 200 F.
Paper or other sheet fibrous material impregnated with or embodying various insoluble soaps or so-called synthetic waxes, also possesses the characteristics of, and is within the scope of myinvention. Such insoluble soaps are solids at climatic temperatures and have melting points around 270 F.'more or less, and can be composed of Montan, carnauloa, or candelilla wax,'stearic acid, andother ingredients. For instance, I find that compositions about as follows are suitable for the purposes of my invention,
namely p 1) Montan wax.. "500 g Stearic acid 270 'g. Soda ash solution 15 g. Magnesium acetate solution 17 g.

For my urposcs this composition is mixed with para oil in about the proportions of ten parts composition to one part oil. Y
Y The proportions of the ingredients of the several compositions can be-varied and also equivalent each composition, and I do not wish to limit my invention to the compositions as outlined but wish to cover and include-sheet material'possessing the characteristics of my substances suitable for the purpose; may be included or embodied therein. In the compositions indicated caustic solutions of other metals than aluminum can be employed to form an insoluble stearate or palmitate (for example, such as lead). Paper or other fibrous sheet material of my lnvention hereinbeforedescribed possessing the characteristics substantially as ingredientscan be employed in- I compositions or pointed out, can be put on the market in various forms, and shapes for container capping and other purposes, and-I'do not wish'to limit all features of my invention to the flat disk form, hereinb-efore described.
For instance, in Fig. 5, I show such sheet material of my invention in premolded, drawn or pressed into flanged, skirted or flared'hood-cap form, for'the market. These caps 7, of Fig. 5 can be prepared for the market from the flat disks of Figs. 1 or 2, either impregnated at the lower edge or securing portions of their skirts 7, on impregnated throughout. These flared skirted caps are usually pressed or drawn by dies from commercial sheet paper such as pulp board, as hereinbefore described, and then impregnated with any one or more of the commercial or synthetic waxes hereinbefore mentioned, as described in connection with the flat disks. .Surplusor surface coating wax is preferably removed from the skirted caps, before they are ready-for packing and shipment.
These skirted treated caps, are flared so that they can be nested to reduce the s ace required for packing, and also to facilitate the application thereof to bottle months. These flared skirted caps are softened by heat before or afterthey are slipped onto (2) Carnauba wax Q. 420 g. the bottle mouths, and while-so softened, any Stearic acid "420 g. suitable means is utilized to contract the Magnesium acetate solution 15 g. securing impregnated portions of the cap Caustic aluminum solution about skirts, to fasten and secure the caps on the bottle mouths, by the cooling and setting I thereof, as hereinbefore described in connec 1 tion with the flatimpregnated di sks.
