Patented Aug. 24, 1943 NT OFFICE 2,327,965 r NONREFILLABLE PAPER BOTTLE Lydia B. Koch, New Yo NewRochelle, N. Y. said Koch rk, and Irving F. Mandell, said Mandell assignor to Application :Iuly 5, 1939, Serial No. 282,924 3 Claims. (01. 229-56) This invention relates to paper containers, with special reference to bottles constructed wholly of paper, including the top and bottom closures, and is addressed to methods for hermetically closing the ends.
The art of making paper containers for storing liquids, has advanced materially within the past decade, so far, in fact, that small improvements, tending to strengthen, lighten and decrease the liability of leakage, becomes potentially valuable.
With these matters in mind it is an object of the invention to provide a method of stoppering such containers whereby the mouth closure, after having been inserted and sealed becomes irremovable, except by violent disrupture, assuring the contents of the container to be in its original condition, inviolated, and free from substitution, tampering and deterioration, even by air.
A further feature resides in the provision of a bottom closure for such containers, re-enforced by integral ribs materially strengthening the structure up to a point completely resistant of both internal and external strains, short of actual demolishment, permitting the use of light material.
Finally to produce a paper container combining the foregoing features in a single structure, and at substantially no increased expense over the usual forms.
These highly important characteristics are accomplished by the novel means and processes hereinafter described and illustrated in the annexed drawings, constituting a graphical component of this disclosure, and in which:
Figure 1 is a partial side elevational, partial vertical sectional view of a complete embodiment of the invention.
Figure 2 is a similar, but fragmentary, view of the upper portion of the container with a stopper disc inserted therein, and drawn to an enlarged scale.
Figure 3 is a fragmentary longitudinal sectional view, drawn to a further enlarged scale and showing the disc and adjoining parts of the con tainer wall provided with an adhesive.

Figure 6 is a top plan view of the bottom closure.
Figures 7, 8 and 9, are edge and sectional views of the bottom closure, illustrating advanced stages in its construction.
Figure 10 is a partial side elevational, partial sectional view showing the closure as assembled within the shell of a container.
Figure 11 is another like view of the same after v enseaming the closure in the bottom edge of the container shell.
Figure 12 is a transverse sectional view taken on line |2-l2 of Figure 6.
'I'he frustro-conical paper bottle, illustrated in the drawings, exhibits material improvements at its top over any known patents or structures in the multifold formation of the mouth rim and method of positively and permanently securing a closure disc.
'As shown, the bottle consists of a lower, main cylindrical body portion is on which is fixed a conical upper part I6, having a plurality of uniformly spaced grooves ll, of constantly varying cross section, wider and also deeper at their upper ends I 8 and blending at their lower ends into conical surface, as at i3.
It is to be understood that while a two part structure is indicated, the improvements are equally applicable to a unitary structure.
In any event the upstanding portion of the tapering neck 20 and including the upper ends of theundulated elements, are formed by crimping and spinning to produce a curved annular bulge 2|, terminating in a re-entrant curve 22 leading to a straight walled cylinder 23.
The loweredge of the cylinder is turned sharply inward to constitute a level ledge or seat 24, re-enforced by doubling closely upon itself, as at 25, the continuation 26 of which is curved upwardly, in juxtaposition with the inner surface of the bulge 2|, as at 27.
The upper extremity 28 of the element 21 is bent sharply downwardly, as at 29, forming a re-enforcement for the cylinder 23, against which it makes intimate contact, to a reentrantly turned short curve 30, thence upward, as at 3|, in snug contact with the element 21, ending in the space between parts 21 and 29.
The exposed faces of the cylinder 23 and seat 24 are supplied with an adhesive, shown at 32 and 33 respectively, on the latter of which is deposited a paper disc 35 to form a closure to the bottle mouth.
After the disc has been inserted a further spinning operation is performed by which the several upstanding elements 2|, 22, 23, 21, 28 and 29 are forced inwardly and downwardly over the margin of the disc, positively confining it, additionally to the adhesive, by doubly enseam'ing and sealing.
From the foregoing, it will be clear that the bottle can be opened only by complete disruption of the disc, or upper surrounding elements of the bottle mouth.
A closely similar condition is exhibited in the manner of securing the bottom closure, which, in the present disclosure, indicates an advance in the art, in that the closure element is materially strengthened and re-enforced in a manner not heretofore known in the construction of paper containers.
Such closures for the larger endsof bottles are usually of very considerable area as compared with the mouth closures, and failure is known to have frequently occurred, unless extremely heavy and stiff material was used.
In Figures 7 to 12 the various stages of bottom closure construction are clearly indicated.
These include the production of a fiat disc 40 of circular shape; press forming the blank to present a central, slightly conical raised surface 4!, having a plurality of radial ribs 42 pressed outwardly from its surface, a circular center 43, from which the ribs radiate, and a fiat marginal surface 44.
The margin 44 is die formed to produce a cylindrical skirt or band 45 to closely fit in the container shell l5, presenting the conical surface upwardly and eventually the skirt is infolded by spinning to produce a doubly seamed joint 46, which may be further secured by an adhesive. preferably applied to both surfaces of the skirt, rendering the joint capable of resisting any internal pressure to which the bottle may be subjected and obviously constituting an impervious closure.
This construction enables the use of quite thin, but strong paper, which may be treated while in sheet form to resist penetration by liquids, and it is to be understood that all exposed surfaces of the container, particularly at the juncture of the closures, are subjected to a coating of suitable liquid proofing substance.
Although the foregoing is generally descriptive of the best known embodiments of the invention, it is to be understood that all matter herein is subject to such minor changes and modifications as may arise in manufacture that fall within the concept of the scope of the appended claims.
Having thus described the invention and set forth the manner of its construction and application, what is claimed as new and sought to secure by Letters Patent, is:
1. In the process of forming a top closure for paper bottles adapted to contain liquids, the steps which consist of convexly curving the upper end of the bottle thereby to form an annular bulge, re-entrantly turning the rounded upper edge of the bulge to blend into a straight walled cylinder, forming a transverse inreaching ledge at the lower end of the cylinder, layering the material to reinforce said ledge and bulge, turning the material at an arcute angle to produce an annular reinforcement for the cylinder, disposin a paper disk on said ledge, and spinning all of the several elements extending above said disk to cover the margin therewith, thereby to bind it permanently on said ledge.
' 2. In a liquid containing paper bottle having a multiple walled annular mouth convexly curved exteriorally in cross section, and an inreaching transverse annular ledge in said mouth, the inher element of said mouth wall extending upwardly as a cylinder therebeyond to such distance that when it is curled inwardly it extends over the extreme inner edge of said ledge, and a flat paper cap permanently secured between said ledge and the inwardly curved portion of said mouth wall.
3. In a liquid containing paper bottle havin a multiple walled annular mouth convexly curved exteriorally in cross section, and an inreaching transverse annular ledge in said mouth, the inner element of said mouth wall extending upwardly as a cylinder adapted to be curled inwardly and downwardly, to extend over the extreme inner edge of said ledge, a flat paper cap held stabilized between said ledge and the inwardly and downwardly portion of said mouth wall, and an adhesive applied to said ledge prior to curling said mouth wall.
