My invention relates to an improvement in cocktail shakers, the object being to produce a shaker of superior convenience, appearance and effectiveness, constructed with particular reference to preventing the escape of any fluid, no matter how violently it is shaken.

With these ends in view, my invention further consists in a cocktail shaker having certain details of construction and combinations of parts as will be hereinafter described and particularly pointed out in the claims.

In the accompanying drawing:

Fig. 1 is a broken view, partly in elevation and partly in vertical section, of a cocktail shaker constructed in accordance with my invention;

Fig. 2 is a detached view, partly in elevation and partly in vertical section, of the cap thereof;

Fig. 3 is a similar view of the upper portion of the container thereof;

Fig. 4 is a view in transverse section on the line 4—4 of Fig. 3; and

Fig. 5 is a detached perspective view of the removable strainer, looking at its under face.

In carrying out my invention, as herein shown, I employ a cylindrical container 10 contracted at its upper end to form a tapering top 11 which merges into a slightly-conical neck 12 terminating in a flaring lip 13, the parts named being preferably made integral, though that is not essential. With such a container, I employ a cylindrical cap 14 corresponding to it in diameter and having a relatively-flat top formed with concentric shoulders 15 and 16 and provided with a handle comprising a two-piece sheet-metal grip 17 and a nut 18, into the upper face of which the main part of the grip is inserted and soldered in place. The said nut 18 receives a screw 19 passing upward through the center of the top of the cap 14, to which the handle is thus firmly secured. A slightly-conical, annular, sheet-metal stopper 20 of about half the depth of the cap is located concentrically therein and has its upper edge soldered as at 21 within the shoulder 15 in the top of the cap 14. The taper of the stopper 20 corresponds substantially to the taper of the neck 12 of the container, as shown in Fig. 1, the parts being so proportioned that when the shaker is held by its opposite ends in the hands as in use, the lateral pressure upon its ends will tend to crowd the conical stopper into the flaring neck 12 and effectually seal it. In this connection, it will be noted that a slight clearance 21a is provided for between the lower edge of the cap and a shoulder 22 formed near the upper end of the body of the container. But it is to be understood that when the cap is applied to the container, the stopper 20 fits into the neck 12, so as to seal it and prevent its contents from escaping. The point made above is that the harder the shaking, the tighter the seal. The snug fitting of the lower end of the cap over the upper end of the container as at 23 constitutes an additional safeguard against any escape of fluid from the shaker.

Within the lower end of the neck 12 of the container I locate a fastening-ring 24 soldered or otherwise secured in place and struck-up at spaced intervals to produce locking-bosses 25 which enter inset bayonet-notches 26 formed in the upstanding flange of a shallow cup-like removable strainer 27 having an upstanding faceted handle 28 provided for readily rotating the strainer within the ring 24 sufficiently to engage and disengage its notches 26 with and from the locking-bosses 25.

The flange of the strainer is turned outward to form a lip 29 which, when the strainer is in place, rests upon the upper edge of the ring 24, as shown at 30 in Fig. 1, but this is not essential.

As shown, the lower end of the container is formed with three concentric inwardly-struck bands or fillets 31, while the cap 14 is provided with two of such fillets 31. But these fillets are purely ornamental and may be omitted, though they give the finished shaker a high degree of style in the modern taste for design.

My improved cocktail shaker, as thus shown and described, in addition to being relatively simple in construction and convenient to use, effectively prevents any escape of liquid during the shaking operation, without any particular precautionary measures to that end—in fact, the harder it is shaken, the more effective the sealing action of its cap. The shape given to it by the character of its construction gives it a high degree of attractiveness.

I claim:

1. In a cocktail shaker, the combination with a cylindrical body formed at its upper end with a tapering top merging into a tapering neck extended to form a flaring lip, of a cylindrical cap substantially corresponding in diameter to the diameter of the container, its lower edge fitting snugly over the upper end of the body thereof, a handle for the said cap, a conical sheet-metal stopper secured by its upper edge concentrically within the cap and fitting within the tapering neck of the container, and a removable strainer located within the lower end of the neck of the container.

2. In a cocktail shaker, the combination with a cylindrical body formed at its upper end with a tapering top merging into a tapering neck extended to form a flaring lip, of a cylindrical cap substantially corresponding in diameter to the diameter of the container, its lower edge fitting snugly over the upper end of the body thereof, a handle for the said cap, a conical sheet-metal stopper secured by its upper edge concentrically within the cap and fitting within the tapering neck of the container, a retaining-ring fixed within the lower end of the neck of the container and having locking-bosses, and a removable strainer having an upstanding flange formed with locking-notches for coaction with the said bosses of the retaining-ring and also provided with an upstanding handle.
