Cork I3 is preferably glued or cemented to shell 6|.

In Fig. 4 the cap has the outer element or shell 4| and the element 42. Shell 4| has the top 40 from which downwardly extends ring or skirt portion 4| bent inwardly at ll, a space being formed for the reception of the downwardly extending annular flange 42' depending from the ring-like flat portion 22 of insert 42. The por-- tion 42' is clamped between the wall 4| and flange 4|". Depending from flat portion 42 at its center is the hollow projection or extension 43 having the closed bulbous end 2|. The cork I3 is secured to the flat portion 42 and extension 43 of element 42 by any suitable means, such as, cement. The space between the tops of the ele-' ments 4| and G2 may be occupied by a filler or spacer disc 2 made of suitable material, such as, for example, cork, fibre, paper or composition.

In Fig. 5, the inner shell 35 is provided with the threaded depending portion or skirt 32, for engagement with the complementary threads 3| of the neck 38 of a container. The threaded portion 32 and depending hollow central projection 38 are confined within the outer shell 36. The lower edge of the threaded skirt 32 of element 35 is clamped between the cylindrical wall of skirt 36 of shell 36 and its inturned edge 34. The top 33 of the outer shell and the top 35 of the inner shell contact each other. The central projection 33 may be provided with the end prongs 22 extendingin an outward direction and formed after the cork 31 is fixed to inner shell 35 and in the manner similar to that hereinbefore stated with reference to prongs 2| Unscrewing the cap forces cork 31 upward sufficiently to overcome the initial tightness between it and the neck of the bottle, thereby permitting easy removal of the cap from the bottle by a lineal pull.

In Fig. 6 the cap has a top recess 53. Shell 50 is cup-shaped having the annular flange 50 which is clamped between the inturned inner annular wall and outer annular wall 5|" of shell 5|. Shell 5| has the projection 52 received in the cork I3, and cork |3 is suitably secured to projection 52 and the bottom surface of shell 5|, as by cement or glue. I

In Fig. '7, the cap comprises the outer shell 56 and inner shell 54. Outer shell 56 is cup-shaped having the depending circular wal1 56'. Inner shell 5:1 has a central annular recessed inward projection 55 for receiving the upper portion of cork or stopper l3 towhich it is secured by any suitable means, and further has a ring-like bottom 54 and upstanding circular wall 54 the upper edge of which rests against the top of outer shell 53. The two shells are firmly fixed to gether by turning in the lower edge of wall 56 as indicated at 5'! so that it engages the ring 54.

As depicted in the above embodiments of the invention, the closure is a combined cap and stopper which comprises three elements, namely, the two preferably metallic shells in interengagement and a stopper or plug secured to one of the metallic elements, the latter being provided with a projection or depending wall in engagement with the stopper to facilitate said securement.

The interlocking cap members or shells are each formed from a one-piece metal stamping, one of the shells having the projecting wall to which the stopper is secured.

The closure may be suitably embossed, or lithographed or otherwise printed. I

In the accompanying drawing I have illustrated the invention embodied in some of its practical commercial forms but as these illustrations are primarily for purposes of disclosure it will be understood that the invention is not limited to these particular forms of structure and that it may be modified in many respects without departure from the true spirit and scope of the invention as herein defined and claimed. I wish it further understood that the terms which I have employed herein are used in a descriptive rather than in a limitating sense, except however, for such limitations that may be imposed by the state of the prior art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A closure comprising a combined cap and stopper, said cap comprising two interconnected members, one of said members being of sheet material with a peripheral off-set flange secured to the other member, said one member having a depending centrally disposed tubular projection extending into an end of' the stopper only partway of the length thereof and securing the cap to the stopper.

2. A closure comprising a combined cap and stopper, said cap comprising two interconnected members, one of said members being of sheet material with a peripheral off-set flange secured to the other'member, said one member having a depending centrally disposed tubular projection extending into an end of the stopper only partway of the length thereof and securing the cap to the stopper, said projection having an approximately closed free end to add rigidity to the walls thereof.
