CLOSURE FOR RECEPTACLES.

Speeication of Letters Patent.

Patented July 16, 1918.

Application filed November 27, 1915. Serial No. 63,702,

To all whom t may concern.'

Be it known that I, ROBERT A. RUSSELL,

residing at New York, in the county of Newv closure comprising a cover part and a tubular art, the cover part being' adapted to l over 1e the openlng in the bottle neck and the tubular part being adapted to encircle the exterior walls` of the bottle neck and having means to draw down the cover part tightly into sealing engagement with the lupperendof the bottle neck, and to provide meansv interengaging betweenA the .closure and the bottle adapted to prevent accidental loosening o f the cover part from sealing engagement. I

A further object isto provide a closure having a threaded part for engaging the bottle neck, and to provide a sleeve associated therewith for gripping a portion of the bottle neck to prevent detachment of the tubular part, the sleeve preferably possessing the quality of losing its grip upon the bottle when the tubular part is forcefullyrotated and thereby moved upwardly owing to the engagement of its threads with the threaded surface Vof .the bottle, and said' sleeve further preferably possessing the quality of indicating by its condition any unwarranted tampering with the closure.

A further object is to make the sleeve above referred to as a separate member, if

arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to' be taken as a part of this specification,

and in which I have shown a merely preferred form of embodiment of the invention:

Figure l represents a vertical central sectional view through a closure constructed in accordance with the provisions of this invention.

Fig. 2 represents a similar view illustrating a modification.

Fig. 3 represents a top plan View of the structure shown vin Fig. 1'.r

Fig. 4: represents a top plan view of the structure shown in Fig. 2; and

Figs. 5 and 6 illustrate further modifications.

Referring to the dra'Wings for a detailed 'description ofthestructure shown therein, the reference character L indicates the cover part of the closure, G the tubular part, and H the sleeve. These parts are each preferably formed of sheet metal, such as tin or the like/preferably lacquered upon-all .its surfaces soas to avoid corrosion in cases where the metal itself is subject thereto.

The cover part comprises a disk of a size to coverthe upper end of the bottle neck. Its exterior surface may be ornamented in any desired manner, as by embossing or lithographing.

The tubular part is preferably made as a Y sheet of metal bent around into tubular form and seamed together at its edges as indicated at l in Fig. 3. The upper annular edge of the tubular part may be connected to the peripheral portion of the cover part in any manner, but is preferably connected by means of a seam, as shown at 2. The form of the seam, so far as the present invention is concerned, is immaterial, except that an advantage results in so forming the seam that a portion thereof projects above the exterior surface of the cover .part so as to serve as a protecting ridge about the ornamentation which may be carried upon the outer surface of the cover part, and except also that an advantage is provided by making the inner annular portion of the cover part bent slightly downwardly where' the seam is 'formed so as to provide a part 'adapted to hug more closely about the upper A linmg member or gasket 6 .is arran ed within the closure vagainst the inner sur ace of the cover part.

By rotating the tubular part downwardly about the threaded surface of the bottle, the lining member 6 is brought into engagement with the upper surface of the bottle neck. A little force applied in rotating the tubular part downwardly causes the member 6 .to constitute an effective seal for the opening yin the bottle neck.

The' sleeve H is designed primarily to prevent any rotation of the tubular part from a position in which it holds the member 6 in vtight sealing engagement. rIhis sleeve preferably comprises a strip of metal bent around the lower annular edge of the tubular part and connected thereto as by a seam 7. It may, however', be formed integrally with the tubular part 'if expedience so dictates. Prior to screwing the tubular part down upon the bottle neck the lower annular edge of the sleeve projects straight downward as indicated by the dotted lines in Fig. l. After the tubular part has been screwed home then the lower annular edge of the sleeve is bent inwardly, as at 8, so as to engage rmly beneath the under surface of ain annular bead 9 formed upon the bottle nec l The firmness with which the portion 8 grips the bead depends upon the extent to which it rojects beneath the bead, to the shape of t e under surface of the bead, and to the stiffness of the material of which the` sleeve is composed. Preferably these elements are arranged so that the sleeve will constitute a grip which is amply suHcient to retain the tubular part against any rotation under all ordinary, or even slightly excessive, conditions. When, however, a highly excessive forcelis applied to rotate the tubular partthen the grip of the sleeve v will loosen, the part 8 will be caused to bend outwardly, and the closure will thereafter be easily removable.

In case the closure has been loosened by unauthorized hands, the condition of the sleeve after having been once removed as above, will serve as an eiiicient indication that the closure has been tampered with.

In the modification, Fig. 2, the sleevev is not only formed as a separate member, but

it is so shaped as to be easily detachable from the remainder'of the closure after the bottle has been once opened.v y

In Fig. 2 also the parts L and Gr are shown integral with each other. In this instance the sleeve may be made without a seam, as shown in Fig. 4. A seamless sleeve of this nature may be also employed in connection with cover and tubular parts which are seamed together as in Fig. 2l,V such an arrangement being shown in Fig. 6. A structure 'in which the cover and tubular parts are seamless, and in which the sleeve is formed of a band of metal seamed together is shown in Fig. 5. Such structure is preferably employed in connection with a seam such as' shown at 7 in Fig. 1.

It will be understood that various changes may be made in the form, construction and arrangement of the several parts and hence I do not intend to be limited to the details herein shown and described, except as they may be specifically included in the claims. Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

- 1. A screw closure "comprising, a threaded body portion adapted for coperative engagement with a threaded' receptacle for drawing the closure into sealing engagement therewith, and a vbendable sleeve depending from the lower part of the body portion and rotatable with respect thereto, said sleeve being adapted to .be crimped about a beading on the receptacle for normally holding the closure in sealing position, whereby the forcible unscrewing of the closure will break the engagement of the sleeve with the beading and permit the removal of the closure.

2. yA screw closure comprising, a threaded body portion adapted for coperative engagement with a threaded receptacle for drawing the closure into sealing engagement therewith, and a removable bendable sleeve depending from the lower part of the body portion and rotatable with respect thereto, said sleeve being adapted to be crimped about a beading on the receptacle for nor- 'lower edge turned upwardly, and a bendable sleeve having its upper edge turned downwardly for rotatable engagement with theV y ilpturned edge ofthe body portion, said sleeve being adapted to be crimped about a In testimony whereof I ailix my signature beading (n the receptzcle for normallholg.- in the presence 'of two Witnesses. n the c osure in sea in ostion w ere y th forcible unserewinggofp the closure Will ROBERT A' RUSSELL' 5 break the engagement of the sleeve with the Witnesses:
