CONTAINER Filed July 7, 1938 l ATTORNEYS Patented sept. 17, 1940 UNITED STATES amazes CONTAINER Vitalis nimmer, Monntnin Lakes, N. J. Application July 1, 193s, serial No, 217,930

s claims.

This invention relates to an improved container for the storage and shipment of liquids.

A further object of the invention is that of furnishing a unit of this character ideally suited for the storing and dispensing of carbonated or other liquids having relatively high internal pressure.

A still further object is that of providing-a container from which liquids may readily be dis- |0 pensed and which container may have a sealing means associated withY it to assure of the maintenance of the stored liquid without spillage, deterioration or loss of carbonated gas.

Another object is that of providing a container 1b which will not contaminate or transmit by odor or taste any objectionable characteristics to the liquids contained therein With these and other objects in mind, reference is had to the attached sheet of drawings.

m illustrating one practical embodiment of the invention, and in which:

Fig. 1 is a plan view of the container with certain of the parts broken away to show underlying construction;

Fig. 2 is a sectional view taken along the lines 2-2 and in the direction of the arrows of Fig. 1;

and

Fig. 3 is a perspective view of the top of a container as constructed in accordance with the a teachings of my invention.

This application is a continuation in part of my applicationv Serial No. 92,982, led July 28, 1936.

In the illustrated. embodiment. I have shown my invention applied to a preferredform or arrangement for making a high-pressure resisting beverage container and -it is understood that this islonly illustrative, that certain deviations, substitutes/or mechanical equivalents, or use for non-carbonated or non-pressureV beverages 4or other/liquid or viscous materials, would not deviate from the spirit of the invention.'

Thus a illustrates the outer housing wall or body of thevprimary container structure. 'I'his a wall is preferably made of a plurality of plys or a number of convolutions of suitable paper rolled upon a mandrel with a suitable adhesive between the layers.

The ends of the container are formed by paper 50 discs b and c separated Aand secured together by a stiffening filler plate or `disc d adhesively attached to them. Each of the end discs b is provided wi'th an annular peripheral flange k which contacts tightly with the inner surface of the cylindrical wall a of the container and to which it is secured by suitable adhesive. As will appear from the drawing, said iiange 7c extends outwardly or toward the ends of the container. The-inner cover discs c are similarly provided with inwardly extending annular flanges ll similarly se- Il cured to the inner wall a of the container. 'Ihe embodied means for further securely fastening the end members to the cylindrical container and integrating same therewith comprises the provision of cylindrical extensions at either end of the 10 side wall a of the container, which extensions are curled, clamped or folded and formed .over and inwardly along the inner surface of the anges Ic, 7c and are secured thereto by-suitable adhesive previously applied to the surfaces to be l5 secured. Thus-the flanges 1c, lc of the end pieces b are adhesively attached to the inner walls of the container which are in turn folded over and inwardly and preferably the inwardly folded ends of said container a extend to meet or lie against the outerlgsurfaces of the discs b. The construction, as shown and described, is useful in providing a substantially strong and rigid structure which can be readilyv formed with simple dies or other well 'known' methods and readily assembled. 25

It will be understood, however, that my invention is not limited to any particular physical construction of the end closures ofthe container, as will be clear from the appended claims.

It is to be noted that one end, constitutingv the bottom of the` container structure is preferably made imperforate, and the opposite end assembly, dening the top, is preferably made with an opening for filling and emptying the container. Thus the upper vend p ieces b and c, with the stlffening plate d, before being insertedv and secured to the tubularbody portion a have attached, the neck or spout member'e. This member may be a molded compound and mechanical equivalents may be employed in the formof a o flanged member. with a threaded neck portion, embracing the end parts b and c and secured with a locking nut. Regardless of the material and particular conflguratiomv of-this member, it will be observed that in eifect the stiifening plate d' 45 provides an enlarged flange 'portion forminga part ofthe member.

After the body portion of the container structure is completely assembled, with ends inserted and secured with suitable adhesive and the ends of the body portionl a formed and crimped or flanged over the edges of the end pieces b and b, the container housing form is thoroughly dried to remove all moisture-from 'the adhesive used.

The fibrous structure is now used as a -form to supportv within it, an impervious, tasteless, odorless, non-toxic pressure-resisting, elastic and exible compound, which, when set, constitutes a secondary water and. gas impervious' container within the brous form structure, as illustrated, at h.

I have discoveredthat materials which have a permeation or impregnation characteristic property, as a rule are unsuited as a lining material to resist or sustain pressure. I have also discovered that materials in soluble form, after the evaporation of the solvent, usually leave voidsI when the compoundhas dried or-set; such voids forming minute channels for `the passage and escape of the retained pressure. Such materials as waxes of. all kinds, synthetic rubber compounds, synthetic resin varnishes and lacquers, commonly considered to be impervious are entirely unsuited for resisting air, gas or liquids under pressure; This is; :partly due to the lack of density of the structure or the voids' between crystals. I have found that all soluble compounds, used in liquid state, when dry, retain a considerable quantity of residual solvent for a long time, which imparts to beverages with which it comes into contact, detrimental characteristics either in the form of taste or odor or lchanges'o. temperature and rough handling. It

is of course obvious that if such a film were used f to confine gases or liquids -and fractured,` the gases or liquids, especially if under pressure, would readily escape.

Moreover, inlorcier for the rosin to be employed as a liner material in connection with containers for carbonated liquids it must be free from oils or soft gums containing oils, which would have. a deleterious effect upon the carbonation or 4otherwise detrimentally affect the contained liquid. I have also discovered that the objections are not simply overcome by 'employing conventional plasticizing materials, in that they either reduce the melting point of the rosin compound and/or impart to it an undesired taste or odor. 1 hare, however, found that I can plastlcize a'.:.l compound with a rosin a suitable quantity of polymerized hydrocarbon essentially of straight chain structure.` In other words, there `is included polymerizd isobutylene, which is .af

polymerized product produced from a hydrocarbon derived for example from the refining of petroleum'.

Such a compound results'in a product which These characteristics may be controlled within any desired limits,- depending upon the quantity of the hydrocarbon polymer compounded with -pound is easily accomplished by melting the compound andlpouring it into the paper container form and immediatelyvemptying it. A thin dense glazed iilm h will adhere to the inner surface of the container, forming a quasi glasslike inner impervious container within the form housing which imparts the necessary form, strength and structure, this inner container also possessing great elasticity. Since this plasticized compound has no penetration, saturation or impregnation properties, and' is poured or ap plied into the form in a molten state and emptied immediately in the same manner in which slush castings are molded, it is obvious that the impervious or secondary container is a molded impervious container itself, which acquires support from the rigidifying outer container.

Thus, among others,'the several objects of the invention as specically aforenoted are achieved.-

It will be obvious'that numerous changes in construction and rearrangements of the parts might be resorted to without .departing from the spirit of the invention as defined by the claims, which are: Y

l. A liquid and gais impervious container. for

.packagingliquidsfor human consumption consisting of an interior, impervious lm formed principally from a mixture of resin and polymerized isobutylene-bothof which are tasteless, odorless and non-toxic, said 'film-being supported to resist pressure by means of a rigidifying ible to avoid cracking by normal ilexure caused 'by internal pressure and an exterior supporting structure upon which the film is adherent.

3,'A liquid and gas'impervious container for packaging liquids for human consumption consisting of a continuous interior, water and gasimpervious, dry, non-tacky nlm composed of 5 tof per cent-polymeriz'ed isobutylene and 8 0 to 95 per cent rosin, which is tasteless, odorless,

non-toxic'and suillciently flexible to avoid cracking by normal exure caused -by internal pressure and ari exterior'supporting structure upon which the illm isadherent.
