TAPERED FIBROUS-MATERIAL BOTTLE AND THE LIKE,
Application filed March 14, 1924. Serial No. 699,274.
This invention relates more particularly to the formation of bottom closures for the tapered bodies or barrels of paper or other fibrous material bottles; and the ob ects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanations of the accompanying drawings that illustrate What 1 now believe to be the preferred mechanical expression or embodiment of my 1nvention from among other forms, constructions and formations scope thereof.
An object of the invention is the production of a tapered or conical so-called paper bottle within the spirit and -With an improved permanent comparatively rigid bottom closure.
With this and other objects in view, my 1nvention consists in certain novel features 'of construction and in combinations and arrangements as more fully and particularly explained and specified hereinafter.
v Referring to the accompanying drawlngs forming a part hereof:
per bottle embodying my invention.
of Fig. 1, in sectional elevation.
F ig. 3 is a detail vertical section on an enlarged scale in an exaggerated manner showing a waterproofing and stiffening coating.
Fig. 4t, shows certain mechanism in vertical section, and a paper, disk and a paper bottle body in cross section and in sectional elevation respectively, all to illustrate a certain step in the method of forming paper bottles with permanent bottom closures, in accordance with my invention.
Figs. 5 and 6, are vertical sectional views illustrating additional steps in the method of bottoming paper bottles in accordance with my invention. V
The paper bottle illustrated, embodies a barrel or body 1 in the form of a truncated cone, tapering upwardly from a bottom or base of relatively large diameter to a mouth ible sheet of paper or so-called pulp or paper' board material, of suitable shape, that is bentor rolled around a mandrel so that the longitudinal edges of the blank overlap These overlapping edges are suitably secured together to form a preferably liquid tight pert-- manent joint or seam 1, throughout the length of the tapered or conical paper material body. This tapered body, prior to the formation of the mouth portion and the bottom closure of the complete bottle, is of greater length than the tapered body of the completed bottle. This extra length of the tapered body is taken up in the formation of the bottle mouth and the bottom closure. The bottle mouth in the example illustrated, is formed by a metal neck or mouth ring 2, usually embracing and suitably attached to the upper edge portion of the paper body surrounding the small upper open end of the body. This neck ring forms thecept in so far as may be essential to my bottom Fig. 1 shows in side elevation a so-calledpaclosure.
The bottom of the completed marketable bottle embodies a flanged or skirted paper material disk 3, that is stiff or rigid and permanently centrally eonvexed or arched inwardly (upwardly) and thus held under tension within and closing the large end of the conical body 1. and in the body by a lockcrimp formed by the body end embracing the annular skirt or flange 3* of disk? The lower end of the conical paper body 1, is radially expanded outwardly to form downwardly facing more or less, abrupt annular This disk 3 is permanently secured to I seat or shoulder 1 and depending approximately cylindrical ameter.
The disk 3 is tightly seated and wedged portion 1, of enlarged diagainst said annular shoulder 1 and the disk flange 3 tightly fits within the enlarged cylindrical portion 1 of the body. The annular angular edge portion of the disk 3, at the j uncture between the disk body and its flange, is held compressed against the annular shoulder 1 by the crimp that locks the disk to the body.
The disk 3 and its depending flange, enter a substantial distance into thelower end of the body, and the disk is locked in and to the body to form a permanent liquid tight joint by any suitable means, preferably by any suitable cooperating formation of the body end and disk flange rendered stiff and permanent b paraffin or other suitable stiffening and pre 'erably waterproofing substance or material.
against loosening of the crimp.
The disk flange 3 and the body wall end forming the crimp. are swaged and compressed together longitudinally of the bottle and toward the'annular shoulder 1 of .the body so that the flange 3 may be swaged longitudinally into the crimp, to hold the disk rigidly and permanently to and against the shoulder 1 and against loosening.
The flanged disk 3 is of enlarged overall diameter or is oversize with respect to the internal diameter of the bottle body at or below shoulder 1", to form and maintain the enlarged cylindrical portion 1 and the shoulder 1" of the bottle body and the upwardly or inwardly convexed form ofvthe disk, all'witlr the end in view of producing and maintaining a liquid tight joint between disk and body and maintaining the disk in permanent relative position in the body to avoid variation of the internal capacity of the bottle, after the com- 4 pletion of the bottle.
After these pa er bottleshave been other wise completed, t \ey are usually treated externally and internally with liquid paraflin or other suitable waterproofing-and stiffening material, which on hardening may coat the paper walls, as indicated in a decidedly exaggerated manner by Fig. 3, and one obj ect of the arched or u wardly convexed bottom 3 is to cause the liquid waterproofing material within the bottle to drain to the annular joint 3 and there harden to stiffen and aid in rendering said joint thoroughly liquid proof.
The main objectof employing the bottom disk of oversize -or enlarged diameter is to produce and maintain a tight permanent seal between the disk and bod and cause the disk to assume and maintain t e arch or convexity toward the bottle mouth and a consequent radially outward tension against the surrounding end portion of the body. These paper bottles are of necessity constructed of certain rated capacity, which capacity must be usually indicated on the exterior of the bottle. The bottle must be so made-as to reduce to the minimum possibility of the bottle being increased or decreased in capacity by.
deformation due to handling, shi ment, the weight of the contents or from ot er causes. Heretofore, one cause for the change in capac ity of paper bottles, has been due to the bulgposition of the disk and prevents possibility of upward movement thereof while thetight fitand oversize and tension of the disk and the crimp hold the disk ermanently against downward movement. he permanent upward convexity of the disk is produced during the method of applying and fixing the disk in the bottle and the natural tendency of the disk to resume its natural 'flat form, partieularly under the weight of the bottle contents,
aids in maintaining the liquid tight jo'int between the disk and the bottle bod and'the peic'lmanently fixed position of the isk in the bottles, according to my invention, the extra length open end conical paper body 1, is placed in a tapered hollow mandrel 4, with the large open end of the conical pa er body projecting upwardly through and a distance above, a ring die 5 forming the up or end of the mandrel. The upper end of t is'ring die 5 forms an enlargement 5, providing a shoulder forming ste surrounding the upper end of the bore of t e die and this enlargement 5 is surrounded by a vertical c lindrical wall formed by the inner surface 0 upstanding cylindrical flange 5', at the topof the die. The tapered large end of the paper body projects through the die and a distance above the same, and past the enlargement 5 and annular lip or edge 5".
Referring to Figs.'4, 5, 6, I show a reciprocating punch die 7 for cutting flat large diameter disks 3, from a web of paper a, fed across ring die 6, and deliverin each flat "disk in the die 6, onto the interna upwardly facing shoulder 6,,within said die 6, see Fig. 5, and
' to thereon hold the flat disk pending a. disk fianging operation. While the flat disk is thus held on the flange forming shoulder 6, a disk flanging plunger 8 descends through the hollow or ring punch die7, and enters the die 6 and engages the central portion of fiat disk 3 and draws or forces said disk 3 through opposite the discharge end of thering die 6.
The parts are so arranged and proportioned,
that the plunger 8 will carry the flanged disk directly from die 6 into the lar e projecting: end of the paper body, and W1 1 drive said In the method of bottoming conical paper flanged disk into the body and utilize the same as a die in expanding, swaging, and shaping. the body end into and to conform to the enlargcmentb 'and the annular lip 5", see Fig. 6. The end face 8%, is convexed to produce the desired inward bulge of the disk 3 when within the bottle body.-
The' diameter of the working end of the plunger 8, is less than the contracted bone of flanging died and the internal diameter of the cylindrical end 1 of the bottle body, and hence the flanged disk fits on the: working end of said plungerwith its flange exteriorly'.
surroundin said end and is thus forced into the enlarged end of the paper barrel until the shoulder formed by enlargement 5 and the paper shoulder 1 thereon, arrests further in- (3. the drag of theflange or'skirt forming ac;
tion. will stretch the body of thedisk 3 across and to the bottom face .of the dieor plunger -8 and cause said body of the disk to assume under tension, theconvexed form of, the bot tom face of the plunger 8, and the disk is held to this convexed form as\it enters the upper end of the paper bodyl in the hollow mandrel. However, the disk 3 is not molded or swaged to a permanent non-resilient convexcd form by being ammedand crushed between opposingdies. The disk is drawn under tension to this convex form but constantly, tends to flatten out to its normal or original flat condition. Under this constant tendency to return to its normal flat condition,
this disk in the completed bottle, is held under tension in its convexed form and hence constantly exerts radial pressure against the inner surface of the annularradial enlarged portion 1 of the set forth.
When this ste of insertin the disk and conforming the ottle body t ereto, is completed, the plunger '8, is withdrawn, and the mandrel and its bottle body containing the disk are brought into position for crimping. Any suitable means, such as a rotary crimping head, then acts on the projecting cylindrical end of the paper body to lock the flanged disk in the body, as by the formation of the crimp hereinbefore described. During this crimping operation pressure is applied to the crimplongitudinally of the paper body and toward the small end thereof, and this pressure is sustained by the shoulder formed paper body wall, as herein by enlargement 5, and hence the position of the flanged disk within the body is not changed. It is hence possible to apply the desired heavy pressure during the crimping operation without forcing the flanged disk into the paper body beyond the position prede termined and necessary in a bottle of the desired rated capacity.
No claims are herein made to. the method of and the apparatus for bottoming paper containers, disclosed hereby. as such method and apparatus are claimed in my divisional application Serial No. 283,399, filed June o, 1928.
It is evident that various changes, modifications and variations might be resorted to without departing from 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 bottle embodying a paper material body longitudinally tapering from a largebottom rim to a small top mouth, said body ,having a permanent relatively-fixed bottom closure embodying a flanged paper material disk of oversize spanning the interior of the large end portion of said body and permanently secured therein by crimping, said disk being centrally c'onvexed inwardly and thus permanently held under tension exerting outward radial pressure against said body, said body having a radially enlarged portion and angular shoulderreceiving and against which said disk is permanently held, said disk maintaining the formation of the body providingsaid enlargement and shoulder.
2. A bottle embodying apaper material body longitudinally tapering from a large bot-tom rim to a small top mouth, said body having a permanent relatively-fixed bottom closure embodying a flanged paper material disk of oversize spanning the interior of the large end portion of said body and permanently secured therein by V crimping, said sai disk radially enlarged with the formation of an annular shoulder against which i said. disk is tightly held inwardly, said disk .bein held under tension convexed inwardly and'daeing fixed against longitudinal movement in said body. 3. A bottle embodying a longitudinally tapered body of paper material and the like annular shoulder, and a flanged paper material disk permanently fixed in said enlarged portion of the body by crimping and held upwardly in tight engagement with said shoulder, said disk being centrally convexed upwardly and thus held under tension with a constant tendency to return to flat form whereby the circumference of the disk is held under constant expanding tendency against the inner surface of the body.
large end of the body being maintained by K at its large end portion radially enlarged in 1 diameter and having a downwardly facing 4. A bottle of fixed rated capacity embodying a longitudinal body of paper material and-the like having a permanent liquid tight bottom closurejemhodying an oversize disk fixed in said body against relative longitu dinal movement, the'lower end of the body forming a tight disk holding crimp. roviding thelbottle with :1 depending a r bottom rim, said disk forming and maintaining the endof the'body receiving the same with an annular shoulder seating against and stopping inward movement of the disk and an annular radial enlargement, said disk being swaged into and inset in the body while convexed inwardly to reduce its circumferential diameter and thus held under constant ten-.
dency to return to flat form, whereby the .circumfere cc of the disk is driven radially outwardly nder constant expanding tension against the inner surface of the surrounding annular portion of the body.
5. A bottle of fixed rated capacity embodying a longitudinally tapered paper barrel composed of a folded paper sheet having its ends overlapping and secured together to form disk, said disk being of over-size and shaping the barrel to form a shoulder fitting the top face of the disk and an annularl radial enlargement surrounding and fitting the circumference of the disk and holding the disk under'tensionjn its eonvexed form.
6. A. tapered paper container including a longitudinally tapered liquid tight sheet paper barrel, the lower end portion of which is enlarged in diameter thereby forming said barrel with an intermediate downwardly facing shoulder joining said enlarged end and the adjacent tapered portion; and a transverse permanent inset bottom closure driven within said barrel end andagainst said shoulder, said bottom closure including a transverse upwardly eonvexed resilient paper disk having an annular depending flange, said disk being held. in its convexed form within said enlarged barrel end by a depending annular stiff rim of enlar ed external diameter with res ect to the ad oining tapered portion of'the barrel, said radially enlarged rim formedby crimping together the disk'flange and the barrel end, whereby the load of the bottle contents on the convexed disk tends tomaintain the liquid tight joint between the disk and bottle body.
In testimony whereof I have hereunto set' my hand at Fulton, N. Y., this'13th day of Main, 1924.
