May 27, 1952 J MACEY DISPENSING BOTTLE STOPPER Filed Jan. 15, 1950 INVENTOR ATTORNEY Patented May 27, 1952 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates generally to certain new and useful improvements in bottle stoppers but more particularly to a dispensing bottle stopper.

One of its objects is to provide a bottle stopper of this character which is so designed and constructed as to normally aiford a perfect seal for the bottle-contents and by a relative displacement of its parts cause the bottle-contents to be dispensed or poured in such quantity or at such rate as may be desired.

Another object of the invention is to provide a dispensing stopper for bottles which is simple, compact and inexpensive in construction, and which is composed of two members in telescoping relation with the outer or bottle-engaging member having pouring and vent openings therein and the companion inner member constituting an adjustable valve or closure as well as the control element for positioning the stopper in its seating and dispensing positions.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claim.

In the accompanying drawings:

Figure 1 is a fragmentary sectional elevation of a bottle equipped with my dispensing stopper in its sealing position. Figure 2 is a similar view with the stopper in its dispensing position. Figure 3 is a horizontal section taken on line 33, Figure 1. Figure 4 is an exploded perspective view of the stopper parts.

Similar characters of reference indicate corresponding parts throughout the several views.

By way of example, I have shown my dispensing stopper in connection with a conventional type of bottle Ill having the usual neck I l for receiving the stopper.

In its preferred construction, the stopper consists generally of a cork within a cork so disposed and correlated to seal the contents of the bottle in one position and to permit dispensing of the contents in another one of a plurality of positions depending on the amount of fluid to be dispensed. The outer stopper member I2 is sleevelike or tubular in shape to snugly fit into the neck of the bottle and it terminates at its upper end in an annular flange [3 adapted to abut on its bottom side against the top edge of the bottleneck, as shown in Figure 1. This stopper member may be made of any suitable material and its lower end is fitted with a cork or rubber packing ring I4 to form an eflective liquid seal. The bore or circular opening in this sleeve-like member 12 is preferably eccentrically disposed, as

shown in Figures 1 and 3, to provide a thickened wall It: at one side thereof containing an oblique dispensing port or hole It through which the contents of the bottle is adapted to be poured, the lower or inner end of this port opening into the lower portion of the bore of such sleeve-like member and its upper or outer end opening onto the outer face of the flanged top thereof. In the thinner diametrically opposite wall ll of the stopper member [2 are a plurality of obliquely disposed air vents or ports l8 which open at their lower ends into the bore of such member while their upper ends radiate outwardly through the member-flange l3 into the atmosphere.

Fitted snugly in the bore of the outer stopper,

member to normally seal the lower ends of its pouring and vent ports 16 and [8, respectively, is an axially-shiftable inner stopper member I9 having an annular flange 20 at its upper end for overlying engagement with the companion flange I3 of such outer member in the sealed position of the parts shown in Figure 1. In other words, when these flanges abut, the user knows that the bottle-contents are effectually sealed. The inner stopper member is made of any suitable material and has a cork or rubber packing ring 2! to provide an effective liquid seal between the contiguous walls of the companion stopper members a and about the inner or lower ends of the pouring and vent ports. When the inner stopper member is raised more or less it exposes the lower ends of these ports, in the manner shown in Figure 2, so that when the bottle is tipped up its contents will be dispensed through the port H5 at the rate desired, while air will enter the bottle through the ports [8.

I claim as my invention:

A dispensing stopper for bottles, comprising interfltting inner and outer stopper members for relative telescoping movement to pouring and sealing positions, the outer stopper member being in the form of a sleeve terminating at its upper end in an annular flange to abut at its bottom side against the top edge of the bottle neck and having pouring and vent ports in the sleeve-wall thereof and in intersecting relation at their inner ends with the sleeve-bore above the inner end thereof and opening at their outer ends into the atmosphere, the pouring port opening onto the outer face of said flange, the inner stopper member being in the form of a plug substantially coextensive with the length of the outer member and axially adjustable within the bore of the outer stopper member to regulate the opening and closing of said ports, said inner stopper memher having an annular flange at its outer end for abutting the top side of the companion outer stopper member flange in the sealed position of the parts, and packing rings on said stopper members for providing a liquid seal between them and over the inner ends of the vent and pouring ports and between the outer member and the bottle.
