PAPER BOTTLE.

Specification 'ofLetters Patent.

Application filed February 21, 1919. serialia.'a'zaase.

To all whom it may concern:

Be it known that I, GEORGE R. Iu NN, a citizen of the United States, resldmg at Baltimore, in the State of Maryland, have invented a new and useful Paper Bottle, of

which the following is a specification.

. ferred forms of This invention relates to paper bottles and one of its objects is to provide a container of this character having end closures all portions of which are located entirely within the walls of-the container so that a number of the containers can be packed in a carton which would be too small to hold a like, num-v ber of containers of the same capacity having caps extending around or housing the ends ofthe containers.

A further object is to provide a container utilizing flat abutments or shoulders consti-.

Another obJect is to provide novel means for locking the caps in position. With the foregoing andother objects in view which will appear as the description proceeds, the mvention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the'claims it being understood that various changes may bemade in the proportions and arrangements of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.

In the accompanying drawings the prethe invention have been shown. i

In said draWings- Figure 1 is .a view partly in section and partly in elevation of a paper bottle embodying the present improvements.

Fig. 2 is an enlarged section through a portion of one cap and'showing the means for detachably securing it 'infplace.

Fig. 3 is an enlarged section through a portion of a container and showing a modified means for securing thecap in position.

' Referring to the figures by characters of reference, 1 is a papercontaine'r stiffened or Patented Sept. 9,1919.

reinforced wherever desired by ribs 2 pressed thereinto.

tainer and each is preferably formed with its outer face flat, as at 5, thus to present a flat shoulder or seat for the end closure of the container. These fiat shoulders, 5, are perpendicular to the axis of the container thereby to stiffen the container against pressure along radial lines.

Each closure includes a paper disk 6 so proportioned as to fit snugly within one end portion of the container and to rest upon the shoulder 5, said disk having a flange 7 adapted to fit against the inner surfaceof the wall of the closure and to be supported Stop ribs '3 and 4 are i pressed into the end portions of the conwith its free edge flush with the end of the closure.

For the purpose of stiffening the flange of the closure atone end of the container, parallel rooves 8 are pressed into the inner facet ereof, these grooves also constituting means for facilitatingv the removal of the closure as hereinafter pointed out. These grooves serve to keep the closure in shape rior to its insertion into the container. he closure in the other end of the container and which constitutes the bottom of the device isnot to be removably mounted. Instead it can be held in place by a suitable araflin, or the like, as shown in adhesive, Fig. l or, if preferred and as shown in Fig. 3, an annular groove 9 can be pressed into the flange 'of the bottom closure so that said closure can be snapped into place to bring the rib a into the groove. In either case the connection between the container and the bottom cap is sealed by placing the lower end of the container .in a film of melted paraflin thus to leave a thin layer of the paraffin upon the bottom edges of the container and its bottom closure as shown at 1Q. After thecontainer has been filled With a liquid, powder, or other material, the top closure is inserted thereinto so as to become seated snugly upon the shoulder of the rib 3. By the use of a hand unch or other dcv1ce,.

incisions are made in t e contacting port-ions of the flange 7 and the container wall so as to produce outwardly and upwardly inclined locking tongues or barbs 11 each. made up of the two thicknesses of'materia-l. The thick:

ness cut from the flange 7 will be pressed out into the opening formed in the wall of the container, as shown clearly in Fig. 2. Thus it will be seen that by perforating theflange of the cap and the container at intervals, the cap will be locked securely in position. The cap can be unlocked, however, by pressing the tongues inwardly until they lie flush with the faces of the flange and container wall and fill the openings. By then placing a finger nail in one of the grooves 8 the cap can be pulled out of the container and the contents removed.

If desired, and as shown in Figs. 1 and 2 the top of the container can be sealed by standing the closed container in an inverted position within a film of hot paratlin thus to form a thin layer of paraliin upon the edge of the container and the flange of its cap, as shown at 12. Also, if desired, a small amount of paraflin can be placed in the openings where the tongues 11 are located, thus to close the openings and likewise prevent the tongues from being pressed back into the openings while the container is being handled. However under ordinary circum- .stifi'enin" face )er )endicular to the axis of the container, and a closure insertible into the container and Into engagement with said face. 7

2. The combination with a paper container, of a. stitfening rib pressed thereinto, a flanged paper closure insertible into the container and into engagement with the rib, there being annular grooves pressed into the inner surface of the flange of the closure for holding the closure in shape prior to insertion.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
