To all whom it may concern:

Be it known that 1, WILLIAM H. Rose, a citizen of the United States, and residing at Jersey City, Hudson County, State of 5 New Jersey, have invented certain new and useful Improvements in Package Closures, of which the following is a specification.

This invention relates to closures for receptacles made of paper or other fibrous material.

It is the object of the invention to provide a metal closure which can be easily and quickly applied to a paper or other similar receptacle without the. use of tools -or machinery involving complicated mechanical operations and one which when, in position will be firmly secured to the body of the receptacle and practically non-' removable without destruction of the re: ceptacle itself. 'The invention viewed in a more limited aspect further aims to provide a closure which is so shaped as to support the wall of the receptacle against inward pressure so that crushing or mutilation of the receptacle at the ends thereof is prevented. Cther novel and valuable features of the invention will hereinafter appear.

The invention may be embodied in closures which differ in form and which are ca 1| able of use in different relations and for di 1i? erent purposes. In the drawings accompanying this specification and forming a part thereof T have, therefore, illustrated the in'ven tion applied to various forms of receptacles and closures. Tn the drawings: 'Fig. 1 is a view in elevation showing the closure applied on one end of a paper bottle, I

carton or the like; I Fig. 2 is a vertical sectional view of the to device of Figure 1 showing the construction of one form of my improved closure and its relation to the part of the receptacle to which it is applied;

Fig. 3 is a sectional viewshowing my im- Referring to the drawings in detail the numeral 10 represents in each of the figures t5 the body of the receptacle to which the Fig. 4: is a vertical sectional, view of a por--- closure is applied, such body being made of paper or other fibrous material and having a straight wall to receive the closure or closures applied thereto. The body of the receptacle, as shown in the various figures of the drawing, is made cylindrical although other shapes of body may be employed.

In the construction illustrated in Figures 1 and 2 the numeral 11 generally designates the main body or central" portion of the closure which is formed with an opening in which a removable friction cover 16 is inserted; Aroundthe' central portion 11 in this form of my improved closure there is provided an inner wall 12 and an outer wallor flange 18, these walls being preferably of substantially the same length andextend ing some distance beyond the plane ofthe central portion 11 of the closure. The wallsprefer- 'ably made by striking up or indenting the material of the wall, such prongs pointing toward the base of the flange 13 or toward the bottom of the pocket formed between the walls 12 and 13. The prongs arebent inwardly or toward the wall 12 to a slightextent so that they will be compelled to engage and embed themselves in the material come prising the wall of the receptacle when the an closure'is forced into position.

Tn Figure 3 of the drawing there is shown a receptacle having my improved closures applied to each end thereof, such arrange ment being useful in mailing tubes or any other construction where it is desired to apply both a top and a bottom to a paper-tube; Different forms of closure are shown at the two ends of this figure, it being evident of course, that any of the various forms of clo-x roe sures herein illustrated may be used on the ends of the tube shown in this figure. The closure shown at the-right hand portion of Figure 3 is substantially the same as that illustrated in Figure 2, except that the central portion 11 thereof is not providedwith an opening. This closure is provided with an inner wall 12 and an outer wall 13, the latter having on its inner surface prongs 15 substantially the same as shown in Figure lie 2. The form of closure shown at the left hand portion of Figure 3 comprises a body or central portion 11 which is provided with a wall or flange 13 similar to the wall] 13 shown in Figure 2, this wall 13 being provided on its inner surface with projections 15 substantially the same as those shown in the otherform of the invention.

' In this'for nof closure I dispense with the .themselves in the wal1 o1f;. the receptacle and.

this form of device the closure is alsoproivided with an inner wall 12 and an outer wall 13 between which there is formed a pocket for the reception'of'the end of the receptacle, the outer wall 13? being provided with prongs 15 which arei adapted to embed prevent removal of'Fth'e. closurethereform.

It is apparent' that-giny improved closure can be easily applied-to a paperreceptacle by merely forcing the closure on the receptacle. No tool's-{or machinery are necessary for this operatiomiand it is'further apparent that when employed in-the form shown in Figures2'. and 4 andat the ri ht hand portion of Figure'3,'the wall of t e receptacle will be] braced against external pressure so that crushing or mutilation of the same will not take place.

Furthermore it will be understood that the various forms of my improved closure when applied to a receptacle will be firmly secured thereto, this result being accomplished in each case by the prongs on the outer wall or flange engaging and embed-- ding themselves in the material forming the wall of the receptacle. A closure construct.- ed in either of the ways above described will, therefore, be practically nonremovable when once applied to a receptacle since it becomes necessary to tear or mutilate the paper of the receptacle in order to detach the closure there-from. On account of this secure fastening of the closure to the receptacle, my improved device is of value where a permanent closure is desired for a paper receptacle with or without an opening, and also where as shown in Figure 4, it is desired to provide a closure which will permit use of the contents of the receptacle and at the same time prevent refilling of the same.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is;

1. A construction of the kind described comprising a receptacle having a straight wall of paper or other fibrous material, a nonremovable metallic closure therefor having a body portion and a straight flange integral with the body portion, said flange being shaped to surround and closely fit said wall, said flange having a series of intc gral projections on the inner surface there of extending toward the base of the flange for engaging in the material of the wall and permanentl holding the closure in position when orced on the receptacle.

2. A receptacle having an opening surrounded by a straight wall composed of fibrous material, a metallic closure mounted in said opening, said closure having a central portion lying within the wall of the receptacle, a straight wall on said closure extending outwardly from the central portion thereof and contacting with the inner wall of the receptacle, an outer straight wall or flange on said closure spaced from the inner wall thereof and engaging the outer wall of the receptacle, whereby a pocket is formed between the walls of said closure in which the wall of the receptacle is inserted and held, one of the walls of said closure having a series of integral prongs extending toward the bottom of said pocket for engaging in the fibrous material forming the wall of the receptacle to prevent removal of the closure from the receptacle.

In testimony whereof I aflix my signature.

' WILLIAM H ROSE.
