' Q PAPER'BOTTLE Filed March 5, 1931 ATTORNEY Patented June 6, 1933 UNITED. STATES PATENT OFFICE ANDREW'BODOR, OI NEWARK, NEW JERSEY PAPER BOTTLE Application; fled larch 5, 1931. Serial No. 520,284.

This invention relates to receptacles composed of paper or similar material, with particular reference to milk bottles.

Glass bottles, such as are used for a like and are provided with a removable paper cap of usual type.

A further feature is in the provlsion of a paper milk bottle conforming to the cus- 20 tomary symmetrical shape of a glass bottle,

and so inex ensive that it may be discarded when emptied after use, its cost being less than the expense of collecting, cleaning and sterilizing milk bottles'of glass construction.

. These and other advantageous features, later becoming apparent, are accomplished by the novel design, construction and arrange-- ment of parts, hereinafter described and illustrated in the accompanying drawing, forming'a material part of this disclosure, and in which Figure 1 is a pers ective view of a partially coiled blank rom which the bottle is made. I

Figure 2 is a' perspective view of bottle showing its cylindrical lower portion and rufiled upper portion as conically formed by 0 the first operation.

' Figure 3 is a side elevational view of the bottle after the second, or seat forming and flanging operation, and corrugated bottom.

Figure 4 is an enlarged fragmentary sec- 5 tional view of the upper portion of the same.

Figure 5 is a side elevational view of the completed bottle.

Figure 6 is a fragmentary sectional view of the neck and mouth, showing the cap, seat and bead, and drawn to an enlarged scale.

It is therefore an object of this invention Figure 7 is a similar view showing the bottom construction.

Figure 8 is a fragmentary sectional view taken on line 88 of Fig. 3, drawn to an exaggerated scale.

Figure 9 1s a The entire wall of the bottle is made from a single oblong rectangular blank 10 of suitable sheet material, as heavily calendered paper, uncreased and presenting four straight unbroken edges.

The width of the blankis such as to pro- 'duce a completed bottle, wholly without waste of materiahand itslength is preferably such as to be coiled to constitute two or more fragmentary sectional view similar to Fig. 6, but with the cap omitted.

layers of a thin walled cylinder 11, its edges slightly overlapping and being firmly and neatly secured, both inside and outside, by an adhesive unaffected by liquids.

These cylinders, which are uniform in diameter, length and allother respects, are

placed upon a mandrel, tapered for approximately half the, length of the bottle, and there subjected to a rotating conical die provided with means in connection with the mandrel, to produce a series of evenly spaced, uniform plaits or ruflles 12 widest at their upper extremity and gradually blending, as at 13, into the cylindrical body14.

The extra thicknesses of material at these plaits is condensed under heavy pressure to present an essentially smooth appearance,

and it is to be noted that all of the plaits are folded uniformly in the same direction.

The next operation is to enlarge the mouth portion, that is the upper end, of the bottle by especially designed machinery, at the same time forming a flat'cap receiving seat 15having a raised marginal flange 16 of such height as to permit curling tightly inward uponitself to constitute a condensed head 17 to seat upon and seal the cap 18.

insertion of a disc 20 having a down reaching annular flange 21 closely fitted to the interior of the cylinder, their edges being in register, and prior to insertion an adhesive is applied to the exterior of the flange.

Thereafter a knurling operation is performed on the upper portion of the flange, adjacent to the disc, forcing the material outwardly, in the form of vertical corrugations 22 into the walls of the surrounding cylinder forming a leak proof, permanent joint, the knurling and heading operations .bein'g performed by the use of expansible tools which also hold the flanged bottom in position.

Thisjoint is further secured by coiling the plural walls of the cylinder 14 inwardly to form an enclosing head 23 interengaging the upturned edge of the flange 21.

: The entire bottle may be further sealed by 1 covering the interior and exterior with melted mineral wax, thus efi'ectually sealing the hottle and its content against any possible infiltration of air or leakage of contents.

Due to the plurally layered walls of the 25 bottle an efiicient, essentially rigid structure I is produced, and by reason of designing spe- -cial machinery for its construction, in addition to its simplicity and freedom of waste, the bottles can be produced at a cost comparatively low.

A though the foregoing is descriptive of the preferred embodiment of the invention, it will be apparent that minor chan es may be made in its construction, without t e exercise .of invention or conflicting with the scope of the claim hereto appended.

Having thus descri d the invention, what is claimed as new and desired to secure by Letters Patent, is Apaper bottle comprising a bod having amain cylindrical portion and a nech continuous with one end of saidportion, a bottom for the opposite end of said portion, a cap, ,a right angularly disposed flange extending from the'outer end of said neck and providing at its inner portion a seat for the outer margin of said ca and an inwardly and downwardly turne resilient portion continuous with-said flange and engaging said seat and the outer edge of said cap, whereby, to

provide a V-shapedannular pocket for the' outer edge of said cap. 1
