Application filed July 13, 1918.

be held by frictional contact with the wall of the bottle mouth to form a closure and when raised exposing the opening in the under disk or ring to allow the contents to be poured out, and after partial discharge of the contents the flap can be pressed down again to exclude air and foreign matter from the bottle.

The invention is shown in the accompanying drawing, in which,

Figure 1 is a plan View of the complete stopper.

Fig. 2 is a sectional view, and,

Fig. 3 is a sectional view of a bottle with the stopper in place, the under ring or disk being shown in section and the flap raised.

In these drawings 1 is the under part or disk made-of suitable cardboard, or paper having a discharge opening 2, which may be of ordinary form. To this disk a cover portion or flap is secured by pasting it thereto over the area defined by the hinge joint 3, and the arc 4 extending between the ends of this joint. The cover portion may be stitched along the line of the hinge joint and a'row of perforations, or a scored line may be made at 5, adjacent the line of stitches.

The edge of the cover disk or flap is out out at 6 forming notches in the edge of the cover flap near the hinge joint, and these notches grow deeper toward the free end of Specification of Letters Patent.

the flap. They are intended to enable the edge of the flap near the joint to clear the lip of the bottle and prevent buckling of the thin material of the flap, which otherwise would occur by lifting the flap. Without these notches the edges of the flap working along the convergent or curved contour of the inner edge of the bottle lip would be forced inwardly toward each other, and either cause tearing of the flap at or close to the hinge line or the thin material would he rumpled,and creased from its fiat form, so that in repeated use during the periodic partial emptying of the bottle the cover will not fit accurately upon the under disk and will not be properly seated all around the bottle lip. With the clearance afforded by the notches, however, the flap may be raised and replaced repeatedly without damage thereto, and the original form will be pre served to provide the intended closing effect.

The whole stopper may be covered with paraffin if desired.

The notches are primarily to allow the flap to be turned back at such an angle to the axis of the bottle that the opening is freely exposed and the flap will act as a pouring lip over which the liquid can flow into the glass or other receptacle, and by reason of the clearance afforded by the notches the flap can be turned to the proper angle and yet will present asmooth surface for the flow of the liquid thereon, and without deflecting the liquid.

What I claim is:

A bottle stopper consisting of a perforated disk having a flap hinged thereto, and with notches in its edges adjacent the hinge to clear the bottle lip, substantially as described.

In testimony whereof I aiiiX my signature.
