STOPPER FOR JARS OR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 239,243, dated March 22, 1881. Application filed January 20, 1881.- (No model.)

To all whom it may concern:

Be it known that I, ROBERT GORDON, a citizen of the United States, residing at B0- selle, in the county of Union and State of New Jersey, have invented new and useful Improvements in Stoppers for Jars or Bottles, of which the following is a specification.

My stopper is intended particularly for jars orjbottles in which fruit, vegetables, or other materials are to be hermetically sealed in a partial vacuum.

This invention relates to that class of stoppers employed to hermetically seal jars or hottles containing fruit and vegetables; and the object of the invention is to provide a simple and inexpensive rubbercovered stopper in which the covering is retained in place over the stopper and the latter is adapted to fit the different-sized mouths of the jars or bottles and prevent the contents thereof from gaining access to the rubber covering between it and the surface of the stopper.

To this end my invention consists in a stopper made in the form of a solid or imperforate truncated cone, which is surrounded on its broad end and its tapering sides with a closely'fitting cap of elastic material, the tapering form of the stopper serving to prevent the cap from being forced off the stopper when the latter is inserted in the mouth of the jar or hottle, and the solid or imperforate structure of the stopper serving to prevent the contents of the jar or bottle from gaining access to the elastic cap between the latter and the surface of the stopper.

The invention is illustrated in the accompanying drawings, in which Figure 1 represents a vertical sectional View of the stopper applied to a bottle; Fig. 2, a detached vertical sectional view of the tapering stopper and its elastic covering, and Fig. 3 a side view of the stopperrwithout the elastic covering.

Referring to the drawings, the letter A indicates a solid or imperforate stopper made in the form of a truncated cone, preferably composed of cork or other material which will adapt itself to any irregularity that may exist in the neck-openingof the bottle.

The tapering form of the stopper prevents the elastic cap or covering from being forced 0E the stopper when the latter is inserted in the mouth of a jar or bottle, while the rubber cap, closely fitting the broad top end of the stopper and its tapering sides, prevents the atmospheric air from passing through the pores of the stopper into the interior of the jar or bottle, and the solid or imperforate structure of the stopper precludes the possibility of the contents of the jar from passing to the rubber cap-that is, from gaining access to the elastic cap between the latter and the surface of the stopper.

A stopper constructed as above described is of great advantage in closing or hermetically sealiug the mouth of a jar or bottle of fruit or vegetables, because it is not afi'ected by any acid contained in such substances, and therefore the-contents of the jar or bottle is not changed or rendered unpalatable.

The top portion of the stopper being perfectly plain, it is well adapted to receive an ordinary cork-screw when it is desirable to remove the stopper.

Heretofore a bottle-stopper has been. constructed in which a cork having parallel sides is inclosed within a rubber casing, and the lower portion of the rubber casing has been provided with inwardly-projecting flanges for confining the cork within the casing, as in Patent No. 156,219; but such does not constitute my invention, and is not claimed; and, further, a combined stopper and medicinedropper has been constructed of a tapering stopper having a central passage through it for receiving the dropping-tube,.the sides of the stopper being surrounded by a rubber casing terminating above the corkin an airchamber, as in Patent No. 158,564 but such structure does not constitute myinvention, nor could it be used for the same purpose, as the fruit or vegetables could pass through the stopper and,
