This invention relates to improvements in closures,cand refers particularly to closures for botties, jars and the like.

Itis an object `of the invention Vto provide a closure including a retaining member which` is split and has the adjacent extremities of the split portions and an arm'all held together by a friable joint, either welded, brazed or soldered, so that when the connection is broken the closure may be readily removed.

Another object of the invention is to provide such a closure wherein the arm is so secured that by movement of it the friable connection may be easily broken.

Having thus briefly and broadly stated some of the objects and advantages of the invention I will now proceed to describe it in detail with the aid of the accompanying drawing in which:

Figure 1 illustrates a plan view of one form of the closure, and

Figure 2 is a section on the line 2--2 of Figf of the invention and Figure 6 is a section on the line 6-6 of Figure 5.

Figures 'I and 8 are details showing two slightly different forms of the friable joint.

Referring iirst to Figures 1 and 2, IIl designates the neck of a conventional bottle over the mouth of which a circular gasket II is arranged. This gasket is held in position by a split retaining member I2 which is circular and has a peripheral depending skirt I3 which is crimped to engage the periphery of the bottle neck. The member I 2 is split substantially radially from adjacent one side of the skirt I3 across the said member and down to the bottom of the opposite side of the skirt, and the adjacent extremities of the split member and skirt portion are arranged in overlapping relation as shown at I 4. Between the overlapping extremities of the member I2 an arm I5 is inserted which is connected, preferably adjacent the severed skirt side of the member, to both extremities of the latter by a friable connection as indicated at I6 in Figures 1 and 7. This arm I5 extends across the top of the cap to form a lever rigid in the plane of the surfaces of the split member so that by its movement about the connection I6 in a direction parallel with the plane of the overlapping extremities the said connection may be readily broken and the overlapping extremities of the member I2 released from one another, after which, obviously, the said member and its skirt may be readily removed.

In the modificationshown in Figures 3 and 4, the periphery I Ib of the gasket I Ia is downturned to extend around the bottle neck Ill, anda ring II, made of rubberor other suitable material, is supported by the inwardly exed margin of the gasket periphery. The split retaining member. I2c, in this instance, is substantially annular to bear upon the gasket IIa over themouth of the bottle and has its integral downturned skirt inturned at its lower extremity to engage the lower margin of the gasket periphery IIb. In this instance again the member I2a and skirt 43a are substantially radially split, the split portion extending from the bottom of one side of the skirt I 3a completely across that side of retaining member I2a and at least partly across its opposite side toward the other side of the skirt. The split extremities Illa are again arranged in overlapping relation, and between these overlapping portions an arm I5a rigid in the plane of the surfaces of the overlapping extremities is inserted which is secured to both extremities of the member I2a by a friable connection I6. Thus the connection may be readily ruptured by movement of the arm |511I in a direction parallel with the plane of the overlapping extremities.

In the modication shown in Figures 5 and 6, the cap I I c, which extends over the mouth of the bottle I0, has its periphery downturned to support a suitable ring I'Ia which bears against a bead Illa. formed around the bottle neck and the top of the cap is spaced above the top of the bottle neck. Around the latter a second and lower flange Illb is provided between which and the underside of the downturned gasket periphery a substantially annular retaining member I 2c is provided. This member is transversely Y split and has overlapping extremities I4c which,

together with an arm I5c rigid in the plane of the overlapping extremities of the transversely split member, are secured to one another by a friable joint Ilc. It will be noted in this instance that the two overlapping extremities of the member I2C rest against one another and that the arm |50 bears against the outer of the two overlapping extremities in which case the latter is preferably apertured as shown at 20 in Figure 8 so that the friable connection I6c may be made directly between the arm I5c and the inner of the two overlapping extremities thereby holding the outer extremity between them. Again by movement of the arm I c in a direction parallel to the plane of the split extremities breakage of the connection I 6c may be readily caused thereby rendering the member I2c easily removable. Then the cap llc may be moved downward and slightly tilted to break the vacuum within the bottle after which the gasket may be readily takenoi. Y y

Obviously the f riable connections shown in Figures 7 and 8 may be interchangeably employed with any of the closure forms above described.

- the latter, a lever rigid in the plane of the surfaces While in the foregoing the preferred embodi-` ments of the invention have been described and shown, it is understood that furtherl alterations and modifications may be made thereto provided they fall within the scope of the appendedclaims.

What I claim is: c

l. A closure including a covering means 'extending over the mouth of a vessel, a split retaining memberhaving overlapping extremities holding said covering means in position, a lever arm rigid in the plane of the surfaces of the over lapping extremities, a iriable joint securing said overlapping extremities and one end of the lever arm to one another whereby upon movement of the Varm in a direction parallel with the plane oi' the overlapping extremities said joint is adapted to be broken and said overlapping extremities freed from'one another.A

2. A closure including-a gasket extending over the mouth of a bottle, a retaining member including a depending peripheral'skirt engaging the neck ofethe bottle, said memberholding 'said gasket'in. positiomsaid member vand skirt being split andi having overlapping extremities, a'lever of the overlapping extremities, and a friable connection securing the lever to both overlapping .extremities W-hereby upon movement of said lever A lapping extremitiesthe connection is adapted to be broken.

4( A closure including a gasket extending over the mouth of a bottle, a substantially annular retaining member over the gasket having adepending peripheral skirt, said skirt engaging the neck'of the bottle, said skirt being substantially radially split from one peripheral margin and said split extending at least across the adjacent side of the annular retaining member, the adjacent extremities of the latter and of the skirt lying in overlapping relation, a lever arm rigid in the plane of the overlapping Vextremities of the skirt, and a friable connection securing the arm to' the overlapping. extremities of the skirt whereby when said leverarm 'is sufficiently moved in a direction parallel with the plane ofthe overlapping extremities the connection is ruptured.
