' PAPER CONTAINER.

Application flled Aprfl 24, 1920. Serial No. 376,400.

Theipresent invention relates to aper containers, that is, to containers ma e of any suitable fibrous stock, whether paper or resembling paper, and particularly to the neckand the cap fitted therein. The container may be in the form of a can with a cylindrical side wall, or in any suitable polygonal or curved form, wound or formed 'in any suitable way and having a bottom seal of any suitable kind. The paper stock may be single or multiple ply with or without incorporating a binder, and the container may be coated with parafline or the like and may have a paper covering or advertising label.

I have found it desirable to provide a seat or ledge projecting a considerable distance inwardly of the side wall of the container, for otherwise the ca the contents in sealing the container. In accordance with this part of my invention, the neck, reenforced for strength and formed from a continuation of the side wall so as to be integral therewith, has a ledge which projects sufficiently inwardly of the side wall to form a seat that not only supports the cap over an extended area but practically insures that the cap will not be pushed into the contents. For this purpose the'ledge is formed of a plurality of folded portions, preferably of two, the terminal portion being enclosed between the other port1ons with its end surface-covered thereby or in contact therewith so as to prevent capillary attraction through its raw edge. In the preferred embodiment hereinafter described these folded portions comprise a base portion, an intermediate portion, and a terminal portion folded upwardly between the base and intermediate portions; the intermediate portion having a horizontal part and the terminal portion extending into contact therewith to form the ledge. So also, in this embodiment, the reenforced neck has a cap-retaining groove formed by an outwardly bul mg part, and the ledge projects inwardly o the side wall in uninterrupted conformity .with the lower surface thereof to further extend the seating surface. Preferabl the cap, seated in the groove and on the edge, is, in

order to more'efi'ectively seal the contamer,

gripped on its upper surface by the upper edge of the roove, which extends outside of the upper e ge of the side wall to facihtate the fitting of the cap in the groove. Further is often pushed into than the advantages pointed out above, this specific form of construction compensates nicely for changes in gage dimensions, due to manufacturing inaccuracies and to expansion and contraction of the blanks before they are formed into containers, for the ledge may extend to any required depth witnnthe container.

Whether or not the container has a neck of the foregoing form, but preferably so, the

invention comprehends as another of its parts a paper container in which the upper part of the neck is turned over a ainst the top surface of the ca to tighty seal it therein after filling. lhus, before filling, the conta1ner comprises an upstanding neck which is of a height sufficient to be turned over against the cap, the intention being that the container be su plied to the packer with the neck upstan ing, and that the packer turns over the neck to seal the contents. In the s ecific embodiment hereinafter described, t e terminal part of the neck is enclosed within the folds of the turned over upper portion and preferably extends upwardly into contact with another part thereof so that the possibility of the ingress and egress of moisture or foreign matter between the folds is minimized. In fact this part, turned over against the upper surface of the cap, is highly compressed and ractically solidified to form a rigidly set head, so that the container is securely closed particularly where the ca is gripped between the upper and lower e ges of the cap-retaining groove. Where the previously mentioned ledge, on which the cap is seated, is also highly compressed and practically solidified into rigidly set form, the cap is substantially hermetically sealed in the neck of the container almost indefinitely.

Although the container may ,have any suitable form, I prefer the form of a. firkin wherein the side wall flares upwardly, for then the containers, without the caps, may

be nested in shipment to the packer. Furture or liquids from the contents between the folds formin the reenforced neck. The ressure to w ich the reenforced neck is subected in formin it is made possible by the added stock of-t e folds. a

In the accompanyln .1 drawings Illustrating the preferred em odiment of the 1nvention in application, as an example, to a. firkin of sing e ply stock, having a ermetlcall sealed bottom, ig. 1 is an elevation, partially 1n section and partly broken away in full 'vlew, of the container with the neck upstanding as before sealin Fig. 2 is an enlarged sectional detail of t e upstanding neck with the cap fitted therein; Fig. 3 is a' view similar. to Fig. 1 but with the upper part of the neck turned over: and Fi 4 is an enlarged sectional detail thereo with the neck shown upstanding in broken lines.

The container has an upwardly flaring side wall 1 of paper stock of suitable thickness and surface finish, and a hermetically sealed bottom closure 2 formed by so interlocking and compressing folded portions of a continuation of the side wall with folded ortions of the bottom member 3 as to rigidy set them against penetration and against upward and downward pressure.

The reenforced neck is formed from acontinuation of the side wall and comprises a base portion4, an intermediate portlon 5,

and an abbreviated terminal portion 6 folded upwardly between the base and intermediate portions, so as to have its outer surface in contact at 7 with the base portion and its inner surface in contact at 8 with the intermediate portion. The neck has a cap-re-- taining groove 9 formed by an outward bulge at 10 of the base and intermediate portions, and the intermediate portion has a horizontal part 11 extending inwardly of the sidewall in uninterrupted conformity with the lower surface of the groove. The peripheral surface of the terminal portion 6 is in contact at 12-with the underside of the horizontal part 11 so as to prevent capillary attraction of contents of the container through the raw edge of the paper stock with the consequent contamination and change of the contents. The intermediate portion forms with the terminal portion a ledge '13, which has its inside surface at 14 substantially vertical so as to form an extended seating surface -for a. suitable paper cap 15. Not only does the ledge extend inwardly of the side wall for a suflicient distance to'provide a suitable seat for the cap, but it also prevents the cap from being pushed readily into the contents when sealing the container. Furthermore, although the cap is held against that seat by the upper edge 16 of the groove, that edge lies outside of the upper edge of the side inch. The lower part 0 wall .to enable the cap to be readily fitted in place for sealing.

In order thatthe neck, and particularly the ledge 13, may be rigidly set to permanent gage dimensions, those parts are preferably subjected, in forming, to a pressure of from 4,000 to 6,000 ounds er square F the le go is compressed more than the upper part to bring v. the inner surface thereof substantially ver- --tical and also to force moreintimately into contact with each other the lower parts of the ledge and base portion to thereby more effectively exclude the seepage bf the con-' tents of the containerbetween the folds of the neck. a

' The firkins are intended to be shipped to the packer in the formshown in Fig. 1, the cap 15- being removed to permit nesting. After a container is filled, the up er part of the neck'is turned over against t c upper surface of. the ca into a highly compressed, practically, solidlfied and. rigidly set bead 17, hermetically sealing the. cap in place with the terminal part 18 folded upwardly into contact with another part and enclosed therebetween to prevent the ingress or egress of moisture or foreign matter between the folds of the bead.

A sealed container of this kind, filled with liquids or solids, such as molasses, cheese, etc., may be transported without hazard, and maintain its dimensions and hermetical closure almost indefinitely. Still the container may be readily opened to consume the contents by cutting away the ca 15.
