STOPPER FOR NIUCILAGE-BOTTLES.

SIEGIFICATION forming part of Letters Patent No. 657,051, dated August 28, 1900.

Application tiled April 23, 1900.

described and claimed.

In the drawings forming part of this specification, Figure l is a vertical central section through a liquid-receptaele with my improved stopper or cork applied thereto, and Figs. 2, 3, and 4 represent different forms of the stopper or cork in detail.

Like reference-numerals indicate like parts in the different views.

The bottle or receptacle lis formed at its upper end with an inwardly-extending flange 2, providing a circular opening leading into the body of the receptacle. The stopper or cork 3 is hollow, as shown, has a closed upper end at, and when in place extends down to a point adjacent to the bottom of the receptacle l. In the form of stopper shown in Figs. l, 3, and e the exterior surface thereof is conical or tapering from its upper closed end downwardly, so that when it is inserted into the receptacle l, as shown in Fig. l of the drawings, close contact will take place between the outer surface of said stopper and the inner surface of the tiange 2. In Figs. l and 3 of the drawin gs the inner surface of the stopper or cork 3 is also tapering and substantially parallel to the outer surface thereof. In Fig. 2, however7 both the exterior and interior surfaces of the stopper 3 are cylindrical, whereas in Fig. 4: the outer surface of the stopper 3b is tapering and its inner surface cylindrical.

In using my device the receptacle lis irst partially filled with mucilage or other liquid and the stopper or cork 3 is then introduced into the opening in the upper end of said re Ceptacle, forcing the liquid contained therein Serial No. 13,952. (No model.)

up around the outer surface of said stopper and providing an air-space on the inside of said stopper beneath its closed upper end 4. If there is enough liquid in the receptacle l to reach the point of contact between the outer surface of the stopper 3 and the edge of the flange 2, a seal will be formed at this point by the liquid itself. If the liquid is not forced up to the point named by the stopper 3 itself, the receptacle as a whole may be inverted so as to bring the liquid to a point around the inner edge of the Iiange 2, or the seal between the flange 2 and the stopper 3 may be formed in any other suitable way. In this condition the receptacle containing tho mucilage or other liquid may be shipped or stored for an indefinite time without danger of spilling the contents thereof and without danger of evaporation or drying of the saine. When it is desired to use the mucilage or other liquid, the upper closed end 4 of the stopper 3 is cut off adjacent to the tiange 2, so as to provide access to the contents of the receptacle l through the hollow stopper 3. An ordinary mucilage-brush may be introduced through the stopper 3 to the mucilage at the lower end thereof, and said mucilage is prevented from being forced up into the hollow stopper 3 by the vacuum or partial vacuum at the upper end of the receptacle l outside said stopper. Only such quantity of mucilage or other liquid will pass into the space at the lower end of the stopper 3 as is removed therefrom by the muoilage-brush.

In the form of my invention herein shown the stopper or cork 3 is constructed of animpervious material which may be easily severed-such as soft lead or some alloy thereofand the upper closed end et of said stopper is removed by making a horizont-al cut across the stopper adjacent to the iiange 2. I do not, however, limit myself to this particular construction or material, as the closed upper end of the stopper 3 may be formed in any suitable way and may be removed in any convenient manner.

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

The combination with a liquidrcceptaclc having an inwardly-'extending iange at its upper end, of a hollow stopper or cork of im- In testimony whereof I have hereunto set pervious, severable material having an intemy hand in presence of two subscribing Witgral, closed upper end, the said stopper or messes.
