PAPER BOTTLE INVENTOR WM Ii!- 41- AW ATTORNEY Filed May 29, 1926 Patented Apr. 15, 1930 UNITED STATES ARLINGTON MOORE, OF NEW YORK, N. Y.

PAPER BOTTLE Application filed ma 29,

This invention relates to paper containers,

or bottles and more particularly to those of a type having a permanently attached swivel top which is provided with a port, through which the contents of the receptacle may be poured, when the cap is moved into a position to bring the port into register with a corresponding port in the neck of the bottle.

More specifically, the present invention relates to certain improvements on the type of bottle. shown in my pending application Serial No. 507,371, and has for its objectto simplify the constructions of said prior devices, and to produce a construction which will be at least as durable and rigid as said prior devices and which may be constructed by tools which are less complicated than those necessary for the production of said prior devices.

A further object of the present invention is to provide an improved body construction which will be practically seamless, so that all danger of leakage will be avoided and the side wall of the container will be of uniform thickness at all points, whereby a perfectly cylindrical or conical surface may be provided between the wall and the cap which rotates thereon, so that the cap may seat tightly thereon and still have'the desired freedom of rotation.

For a more completeunderstanding of my invention reference is made to the accompanying drawings in which Fig. 1 is a view, partly in elevation, and partly in central longitudinal section, of a preferred form of my invention. Fig. 2 is a transverse sectional view on the line 22, Fig. 1. Figs. 3 to 6 inclusive are detail sectional views of portions of the side wall. Figs.- 7, 8 and 9 are detail sectional views illustrating successive steps in the operation of forming the cap and its swivel connection with the body.

As shown in the drawing, the side wall 1 of the container tapers uniformly from top to bottom, and is preferably formed by Windinga sheet of the paper stock, which has been cut I out to form a suitably shaped blank, onto a conical mandrel, the contour of the blank being such that, when it is wound thereon, two complete plies of the stock will be formed 1926. Serial 110,112,486.

about the same, so that the end edges 1, and 1 will be substantially opposite each other, or at opposite sides of the middle portion of the sheet, as shown in Fig. 3. The plies of stock, as thus convoluted, are subjected to a very high pressure between conical male and female dies, so that the end portions of the blank, which are at the inner and outer sides of the intervening portion of the sheet, will be pressed toward one another until their in ner and outer surfaces are flush with the inner and outer surfaces of the adjacent middle portion of the sheet, thereby pressing the por tion of the sheet, which is initially held out of contact with the surface of the dies bythe inner end. portion of the sheet, into contact with said die surfaces and causing two right angular bends, or two oppositely disposed shoulders to be formed in the intervening sheet portion, as it extends between the ends of the sheet, and against which the edges 1",

1 abut. The inner surface of the inner end portion and the outer surface of the outer portion are thus made continuous with the respective inner and outer surfaces of the adj acent sheet portions, as shown in Fig. 4. It will be observed that, as thus formed, the thickness of the side wall will not, at any point, be either greater or less than two plies of the stock. The stock also extends practically continuously between the ends of the blank and the intermediate portion thereof, as said ends are pressed with great force into contact with the surfaces with which they abut, so that they are practically welded thereto.

As shown in Fig. 5, the blank may be of such length that its end portions 1 and 1 slightly overlap, in which case, when the pressure is applied, the bends which are formed in the sheet, as it passes between its ends, will not be as sharp as those shown in Fig. 4- and the end portions of the blank will be pressed into a somewhat tapering form, as indicated at l in Fig. 6. In this instance the stock will be somewhat more highly consolidated at the points where there are slightly more than two plies of stock, so that the end portions of the blank will be more securely welded to the adjacent surfaces of the in the construction illustrated in Fig. In practice, the construction last described 1 considered somewhat more desirable than the beyond two plies is distributed, or pressed back into the adjacent portions of the stock, so there is no actual increase in the thickness of the stock at any point, while the welding of the end portions to the middle portions is more effectively performed.

its blanks cut from the same pattern, or

due to changes in humidity of the atrnc here, these variations will be compensated for by the high pressure to which the overlapping portions are subjected.

ln the operation of forming the side wall, internal shoulder 2 is formed against said. bottom being inserted after filling and held in place by bending or rolling the rim portion 9 inward and pressing there 1 st, in a manner similar to that described in connection with the sealing of the closi in my application Serial No.

the formation of the cap and its swivel coiniection with the side wall, the conical e assembled therewith in a manner similar to that described in my pending application, Serial No. 507,371, the conical shell beinserted in the conical side wall, so that ats tightly in its smaller end, and a port formed therein, in such a position that it istcrs, or is in a position to register, when coated, with a port '7 in the side wall. the cap l is forced into the shell 8, so that its flange 5 extends outwardly therein, in close engagement therewith, the relative positions he side wall, shell and cap, before the ng operation is begun, being indicated i '1". It is to be especially noted that the wall It terminates 1 on a line between body part 4- of cap 4,- and the edge 5 of 5, the extremity l of body wall 1 pping the flange 5 for about one-fourth e distance from the body part a of cap 4 edge 5 of the flange 5, and that the 91 extends beyond the edge of the distance somewhat greater than the of the flange. l? ie operation of foldi these parts together is as follows llhe shell 3 is folded inward to such a point that its terminal portion 3 overlaps the terminal portion 5 of the flange 5 for approximately one-third the length of the latter, the line 3' at which the shell 3 is folded reversely being a distance from the edge of the flange 5 equal to about one-third of the length of the latter. The position of the parts at the end of this part of the operation is indicated. in Fig. 8. This and the following part of the operation, described below, may be and in side the other, as the slight amount of excess stock portion 3 of the shell extending rev nay vary slightly in length at diderent which the shell was folded by the which. a bottomll of stiff board is secured, b d 4 f cap 4 t th d f one of the stools which they overlap, preferably are'substantially continuous but are best understood by being divided into component stages for their descri tion. As thus arranged, the flange 5, with the t ainal ely on its inner surface, is then. bent inwarr at the line 3 where the shell terminates tiereon, so that the outer surface of the tern'iina 3 is laid in contact with the in of the flange 5 from the point wh flange was bent inward to the body of cap i, in which position the DUI,

operation will be brought into contact w :h the body part 4: of the cap l, the position of the parts at the end of this operation being dicated in Fig.3. It will be note l thus folded, there will be four thick the material lying within the seam wall, and five thicknesses of materl the end of the side wall.

In the next part of the operation, by means of suitably shaped dies, the various folds, above described, are pressed eutr l high pressure, against a conical roof which corresponds to the outer su side wall, and extends continuou the end of the side wall, so that the yond the end of the side wall are pi ward until the outer surface of tion between the end of the side we. point where the shell is bent inwa flange is continuous with the onc of the side, wall, a sharp outwarr shoulder 3 being formed in the sl which the end of the side wall abut in Fig. l, in which the finished f shown (thickness of parts being nioie or less exaggerated).

[it the same time that'the folds pressed transversely, or outwardly, as chore scribed, they are pressed longitudi y to form a flat rim portion 3?, th of the shell, at the region 8 'i'flllii'i, reversely to form the terminal por pressed against the body portion the mass being thus firmly co I the contacting surfaces are pi sonically welded together into a solid mass, by reason of the high pressure to which the" are e: ijected, forming a liquid tight connection letween the shell. and cap. The compo. in; ing of the side seam of body wall performed this time, it that the closure is not ins when the container is filled an Upon the completion of the up the parts related indicated in .c tapering shell 8, which is new practice tegrally connected with the cap, 5 close contact with the correspondi ing inner surface of the side wall, or is seated thereon, so as to make a liquid tight connection therewith, by its shoulder 3, which enmtaeaa the ring like seam formed by folding together the end portions of the shell and the cap flange is of uniform thickness, except at the point where it is overlapped by the side wall, the latter supplying the difference of the extra fold, so that the inner surface 8 of the seam ring is parallel with its duter surface 9.
