PAPER MILK-BOTTLE.

Specification of Letters Patent.

. Patented June 2, 1908.

Application filed April 14, 1905. Serial No. 255,669.-

To all whom it mag concern: Be' it known that I, JOHN J. BURKE, a citizen of the, United States, residin in Buflalo,

in-the county of Erie and State 0 New York,

structed of paper or analogous material, and

I the principal object of the invention is to in part a cylindrical or tubular body having simplify and chea en the manufacture of receptacles of this cl faracter by assembling and fastening the. component parts thereof in place without the aid of metal or other extra astenings. a

The invention also relates to certain details of construction which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings in Wh1ch,

Figure 1 represents a side elevation of the improved receptacle or bottle. Fig. 2 represents a longitudinal section on line a, a, Fig. 1. Fig. 3 is a central vertical longitudinal section through the improved receptacle. Fig. 4 is a topl plan view. Fig. 5 ls-a to plan view of t e cylindrical body before t e end pieces are fitted in place. Fi 6 is a vertical central section through one o the end pieces detached from the remainder ,of the receptacle. Fig. 7 is an enlarged fragmentary section through one of the ends of the body and one of the end pieces, the end piece being partially fitted in place to disclose the greater taper of the flange of the end piece.

The improved receptacle includes at least a flaring or taperingend and an end piece t ting in said end for closing the opening and also having a flaring or tapering annular flange which fits against the Interior surface of the flaring end of the body.

Im refen'ing to the drawings in detail, like num" als deslgnate like parts.

Th s entire receptacle or bottle is constructed of paper or analogous material and consists of a tubular or cylindrical body 1,-havmg its end portions 2 and 3, tapered or flared, a ottom end piece 4, and a top-,end piece 5. The end iecespr

closures

4 and 5, are of circular disl form and have tapering annular flanges 6 and 7, which are tapered to a slightly greatendeg'ree than the tapered end portions 2 and 3, of the body 1, so that as they are fitted into said tapered. ends, the elasticity of the paper causes the tapering annular surfaces of the ends 2 and 3, and the flanges 6 arid 7, to wedge into close contact.

Grooves 8, are formed at the juncture of the tapered ends with the body proper and the end pieces 4 and' 5, each have a small bead or annular enlargement 9, at the margin of their smaller extremity which are adapted to spring into the grooves to lock the end pieces in place.

In manufacturing thisimproved bottle or receptacle the cylinder body is first formed with the end portions thereof tapered as shown, and the annular interior grooves 8, at or near the jointure points of the ta ered end portions with the remainder of the Ody, the

ower taperedend thereof is moistened or dampened and the lower end piece 4, is fitted in the moistened lower tapered end 3, of the body sufliciently to spring the annular bead or enlargement 9, into the groove 8, as shown in Fig. 2. An annular, groove 10, is now formed or swaged inwardly in the telescoped taperin end 3, and flange 6, to permanently fasten t e lower end piece in place. The article is now dipped into melted paraflin or other suitable water proofing material and is then dried.

In drying the tapered end 3, shrinks upon the end piece 4, and thus more firmly secures the same in place.

The upper end piece 5, which in reality constitutes the stopper of the milk bottle is preferably formed with a flange 7, of greater depth than the tapered upper end 2, of the body so that when fitted in place the flange 7, will project sufiiciently to afford a convenient finger grasp for the purpose of withdrawing the end piece or sto per. 1

To increase the extent of ger grasp, the upper tapered ortion can have two semiclrcular or sim' ar recesses 11, cut in the top margin thereof on opposite sides as shown in Figs. 1, 2, 3, 4, and 5, to expose more of the endvpiece. or stopper at two opposite points. en'the endpieces are in place, their flanges at all points throughout are under compression from the tapered end portion of the body, and provide an annular telescoping sealing portion of fairly wide extent to insure an absolute air and water tight condition.

The upper end piece 5, is likewise water proofed by dipping and is forced into the upper tapered end of the body when it is desired to close the receptacle until the bead 9, springs into thegroove 8.

The great advantages of this improved construction are the simplicity and cheapness of manufacture, the air tight sealing of the end pieces in the body when fitted in'place which is due to the different degrees of taper of the end .portions of the body and the flanges of the end pieces and the perfect sanitary condition of the receptacle.

I claim as my invention.

In a device of the class described a cylindrical body of water-proofed paper having oppositely tapered end portions and annular interior grooves at the ower termination of each of the tapering end portions, a permanent end piece or closure of water-proofed paper comprising a circular disk, a tapered annular flange extending from said dis and tapered to a greater degree than the taper of I the end portions, and an annular projecting bead at the juncture of the flange and disk forming an annular enlargement of rolling or curving outline; said end piece being adapted to be permanently secured in place in one end of the body by first moistening the tapered end portion of the body, then fitting the end iece in position in said end portion 'with the ead sprung into the interior groove.

in said end, and finally forming a groove in the telescoped tapered flange and end portion below the interlocking annular groove and bead, and a removable end piece or closure of water-proofed paper comprising a circular disk, a tapered annular flange extending from said disk and tapered to a greater degree than the tapered end portion of the body and an annular bead at the juncture of the disk and flange; said end piece being adapted to be removably fitted in place with the bead sprung into the annular groove and the tapered flange telesco ed into the tapered end portion, and one o the tapered end portions of said body havin a portion cut away to expose the remova le tapered end piece to afford afin er grasp. for the convenient removal of. sai I end -piece, substantially as set forth.
