Application filed June 21, 1924. Serial 110,721,471.

This invention relates to an improvement in receptacle closures and, more particularly,

screw closures suchas are used in connection with'bottles, jars, and the like, containing foods, for example, catsup.

An object of the invention is to provide such a closure which has very eifective means for preventing corrosion of its parts due to action engendered b the contents of the receptacle, or due to ot er causes.

Another object consists in providing such a closure, the seams of which are rendered very tight to prevent leakage.

Another object consists in providing such a closure which is made from sheet material that has previously been treated soas to cause the closure formed therefrom, without further treatment, to embody the above named features of advantage.

Another object consists in providing certain improvements in the form, construction and arrangement or the several parts whereby the above named and other objects may be efiectively attained.

A practical embodiment of the invention is represented in the accompanying drawings, in which I 0 Fig. 1 represents a detail side View, partly in section, showing the closure in scaling engagement upon the neck of a glass rece tacle.

ig. 2 represents a similar view showing the closure and receptacle after the element for holding the closure in sealing engagement has been stripped ofi.

. Fig. 3 represents an enlarged detail section showing the seam uniting the top to the body of the closure, and adjacent parts.

Fig. 4 represents a detail plan view, partly broken away, of the sheet material from which the closure is made.

Fig. 5 represents a section taken in the plane of the line V-V of Fig. 4, looking in the direction of the arrows.

I have illustrated my invention as being applied to a closure which contains a threaded portion and also a tear-off strip or band at the lower edge thereof, Wlllch band is designed to be bent arounda beadmg on the receptacle to seal the closure in position thereon. The tearing off of this band enables the unscrewing of the closure from the receptacle, and the former maybe used as an ordinary screw closure thereafter untll the contents of the receptacle have been consumed.

The main body portion of the closure is denoted by 1. It is composed of sheet material and united in circular form by an interlocking seam 2. This body portion is provided with suitable threads, in a. well understood manner, for cooperation with the customary threads upon the receptacle 3; and the body portion may also have a knurling 4, as is usual, to assist in the manual operation of screwing it onto or unscrewing it from the receptacle.

The top of the closure'is denoted by 5,

and it may conveniently be united with the body portion 1 by an interlocking seam marked 6, which operation may be performed by a die, as is well understood in the art.

It may be stated that the seams which unite the edges of the body portion and which also join the top to the body portion are folded so as to cover and conceal the edges of the material.

The central portion of the top 5 is desiriably depressed, as clearly shown in the drawings, and the under side of the same is provided with a suitable sealin disc 7 which may conveniently be compose of cork composition, rubber compound, or other suitable yielding material. By forming the tofp 5 with a depressed center, the screwing o t he closure onto the receptacle tends to force the sealing disc not only against the outer edge of the neck of the receptacle, but also, to a slight extent, down within the neck of the receptacle. This is a feature of advantage because it imparts a wedge-like action to the mutual engagement of the disc 7 with the receptacle 3, thereby affording a very tight seal; and also because it enables the disc 7 to cover any tiny fissures which may exist in the neck of the receptacle just below its extreme outer edge, and thereby prevent leakage.

The lower part of the body portion 1 of the receptacle includes a cylindrical do ending stri or band 8, which is free 0 any screw tread. The parts are so proportioned that, when the closure is screwed firmly upon the receptacle, the band or strip 8 will be coincident with the usual beading 9 that is provided upon receptacles of this nature, immediately below the screw thread.

With the closure in thislast nam'ed posltion, it is a simple matter for the band 8 to be acted upon by seaming or spinning rollare, or gripping jaws, so as to crimp its lower edge underneath the beading 9, as clearly shown in full lines in Fig. 1. It

will be observed, at this juncture, that the lower edge of the band 8 is shown ,in its :(glglnal cylindrical form in dotted lines in The act of thusspinnin'g or bending the band or strip 8 around underneath the bead- 4 ing 9 setsup a firm locking engagement 'be-' tween the receptacle and the. closure so as to.hold the said parts in substantially hermetically sealed condition, thereby preventing the access of air to the contents of the receptacle, which is a matter of importance.

One end of the band 8 is developed in the form of a tongue 10 which overlaps to a considerable distance the remainder of the band.

.A scored or weakened line '11 is formed at r the junction of the band 8 with the body porshipped and stored injsealed condition. vWhen it is received by the consumer, it is tion 1 of the closure.

It is intended that the receptacle will be only necessary for the latter to insert the thumb nail be'neath the end; of the tongue 10 and bend the same 'bac'kwardly upon itself in order to obtain a firm gri thereupon. Continuation ofthis manua motion This operation at once breaks the locked sealing engagement, and the closure may be unscrewed to open'the receptacle in the ordinary manner. The condition of the closure after the band or strip 8 has been removed is shown in Fig. 2, .and it will be seen that there remains a complete sightly and satisfactory screw closure which may be used in the customary manner until the contents of the receptacle have been dissipated.

' There is an important practical advantage in this closure arising from the fact that the 1 element which provides for locking the clofibrous material, suchas oiled paper. sheet is represented by 13. I

sure in sealing condition is combined with a complete screw threaded closure, because the unsealing does not destroy the closure asa closure of general utility.

The 'sheet' material from which the 010- sure is made, and, ofcourse, the closure made therefrom, constitute the basic fea tures of my invention.

The material itself preferably consists of sheet metal, such as tin, which has been coated upon one or both sides with some anticorrosive substance, such as lacquer, printing colors, or the like. This sheet metal is represented by 12 (Fig. 5). To one side of the said sheet metal is secured, as by a suitable, adhesive, a thin layer or sheelthof As is well known, the tin is commonly metal of which received in sheets of considerable size and have been lacquered and before they are cut up for the forming of the closures.

As oiled paper suitable for this-purpose and an adhesive suitable for applying it to the sheet material, are both well known commercial articles, thereis no need furtherto describe the character or composition of' either.

By preference, the fibrous sheet 13 is applied to only one side of the-sheet material 12 and, after these two parts have been caused firmly to adhere to each other, the composite sheet is cut up or blanked out and utilized for forming the closure. in a well understood manner, care being taken to so dispose the -materialduring the operations, that'the fibrous sheet or layer 13 will be on the inside of the formed closure, as clearly shown in Figs. '1, 2 and 3.

This oiled paper, or the like, serves as a very efficient protective covering for the the closure is composed, so as to prevent themetal from corroding under the influence of acid or other agentscontained in or .engendered'by the contents coating or layer'of oiled paper, or the like,

adds so much protective value to the lacquer, that a closure free from any criticism in the respect just noted is practically assured.

The great, if not vital, importance of'having a closure for this class ofreceptacles, which is really proof against corrosion, is generally admitted by those familiar with this art, so

that I regard the provision of this material for the manufacture of such closures, and

closures manufactured therefrom, as yery substantial advance steps.

This fibrous layer 13 not only serves to rotect, as above described,'but, owing to the act that it is folded into the seams 2 and 6,

it automatically acts as a packing for the said seams rendering them much tighter than they otherwise would be so as to pre- .vent leakage 'of air or contents.

This fibrous layer also provldes a certain yielding quality to the interior of. the closure, thereby enabling it better to conform to any irregularities on the exterior of-the receptacle.

While I have described and illustrated my invention in connection with a closure of a particular structure, I desire expressly to 7 state that the invention is not limited thereto, since I believe-myself the first to construct a closure of sheet material provided with a fibrous layer adhering thereto.

It will be understood that various changes may be resorted to in the form, construction, composition and arrangement of the several parts without departing from the spirit and scope of my invention; and hence, I do not intend to be limited to the details herein shown and described, except as they may be included in the claims.

'What I claim is:

1. A receptacle closure composed of sheet metal having an anti-corrosion lamina of treated paper, or the like, adhering to a surface thereof, said closure including a folded seam and said lamina being folded into the seam and located on the inside of the closure.

2. A receptacle closure composed of sheet metal having an anti-corrosion lamina and comprising, a body portion, said body portion being bent intocylindrical form and having the meeting edges thereof joined by a folded seam, and a top for closing the end of said body portion, said top being joined to the body portion by a folded seam; said anti-corrosion lamina being composed of treated paper or the like firmly adherent to a surface of said sheet metal, located on the inside of the closure and folded into the seams thereof, thereby protecting the metal and packing said seams to give them additional tightness.

In testimony, that I claim the foregoing as my invention, I have signed my name this 19th day of June 1924.
