PAPER BOTTLE AND THE LIKE.

Specification of Letters .Patent.

Application filed July 17, 1913. Serial No. 779,477.

Patented Aug.18,1914.

To all whom it may concern Be it known that I, WILBUR L.'WRIGHT, a citizen of the United States,- residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Paper Bottles and the like, of which theiollowing is a specificatiom This iirvention relates ,to certain improve- I ments in paper bottles, and the like; and the invention.

objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawings illustrating' what I now believe to be the preferred embodiment from among other formations within the spirit and scope of the An object of the invention is to provide a paperbottle or other receptacle havin its paper wall at its upper end or neck outwardly or bell shaped by the application flared of a neck ring thereto, so that the neck ring rests in the bell mouth and is upheld thereby.

The invention consists in certain novel' features in construction and in combinatlons and arrangements as more fully and particularly set forth and pointed out here inafter.

Referring to the accompanying drawings:-Figure 1, is a sectional view of the neck or mouth portion of a paper bottle or vessel showing the neck ring resting thereon preparatory to being forced down to bell the mouth of the aper vessel and secured.- Fig. 2, is a sectional view of the mouth or i neck of the vessel after the neck ring has been forced down therein and secured thereto.

In the drawings, I show a paper bottle or other vessel wherein the surrounding upright or longitudinal paper wall 1, tapers or contracts upwardly from a com aratively large base to a comparatively sma l neck or mouth, producing a bottle approximately frusto-conical in form, with the paper wall terminating in the top edge 2.

In carrying out my invention, I provide a metal (or other suitable stiff material) annulus or neck ring or vertically arranged sleeve 3, having itslower edge bent or turned inwardly to form an approximately horizontal annular inwardly or radially projecting flange 4, extending into and Surrounding the open center or'bore of the ring. The upper. portionr-of the ring flares or bells upwardly and outwardly and terminates in an exterior dependin annular flange 5, so that the upper portion of the ring is in the form of an invdrted U. The lower end portion of the ring is approximately cylindrical and is of an external diameter to permit said lower end of the ring to freely sli down into the mouth of the paper wall 0 the bottle about to the position disclosed by Fig. 1, of the drawings. After the ring has been placed in the mouth of the paper wall to the position ap roximately as shown in Fig. 1, a suitably s ped plunger or presser head descends on the ring and forces the same downwardly a certain distance with respect to the paper wall approximately to the position shown by Fig. 2. The ring-is longitudinally or vertically formed to flare or hell the mouth or neck of the paper wall outwardly when forced down therein. The downwardanovement of the ring in the paper wall under heavy 3 pressure, forces the neck or'top edge of said wall to follow the outwardly curving upper portion of the ring, and thereby expands, outwardly curls oiyfiares said portion of the wall outwardly with the rim to the form or position indicated by 7, an

so that the outer annular edge portion thereof is approximately curled by and within the ring. The bottle canbe then rapidly rotated against a suitable spinning tool or other imp ement to spin tuck or turn the exterior depending free edge of the ring inwardly below and with the curled top edge 1 portion 7 of the paper Wall and thereby securely lock the ring in the bottle mouth. The flange at the lower end of the ring and located within the bottle mouth, forms a sealing seat for the disks or caps generally employed as closures for milk bottles and machines. The mouths of t e bottles must be strong'enough to withstand the vertical devices of the thrust of the closure disk-tor'cing plungers, without breaking or bending down or otherwise distorting. ll accomplish this desirable result by employing the flaring neck rings with the mouths of the paper walls of the bottles beiled outwardly therein and thereby stiiiened and rendered capable of resisting excessive downward pressure on the rings. The neck ring rests on and in the bell of the paper wall and hence an exceedingly strong durable structure is produced enabling the paper bottles to he successfully employed in filling and capping machinery.

It is evident that various changes, variations and modifications might be resorted to without departingltrom the spirit and scope of my invention, and hence I do not wish to limit myself to the exact disclosures hereof.

What I claim is 1. A paper wall receptacle having its mouth portion formed by a neck ring having an internal closure-se'at-torming shoulder, said ring having a closure-retaining cylindrical portion above said shoulder and flaring upwardly and outwardly above said cylindrical portion and from thence extending outwardly, downwardly and inwardly to form the top edge or the bottle mouth and a projecting exterior run around said mouth,

said ring fitting down within the paper wall of the receptacle, the upper end of said paper wall bodily flaring and curling-outwardly within said projecting exterior rim, the lower exterior edge of the ring projecting inwardly below said curled portion of said wall to lock the ring on the wall.

2. A bottle having a paper material wall, and a neck ring extending down therein and forming the bottle mouth, said ring forming a sealing-disk shoulderand flaring upwardly above said shoulder and curving upwardly, outwardly and downwardly to form said mouth with'a curved top edge and a projecting exterior rim, the upper end of said wall belling and curling outwardly and downwardly within said curved top and rim of said ring to support said ring against collapse of said wall under capping and filling machine pressure on the ring andits shoulder, the exterior annular edge or said ring extending inwardly below said curled end of said wall to lock the ring thereon.

In testimony whereof ll afix my signature in presence of two witnesses.
