SOUTHWICK, JR., QF WHEELING, WEST VIRGINIA, ASSIGNOR 'I O HAZEL- A'ILAS GLASS C0., OF WHEELING, WEST VIRGINIA, A CORPORATION OF WEST VIRGINIA REQEPTACLE AND cLosURE afirmaron wise.

yA further obj ect of the invention is to pro.-

vide a cap which permits readv removal from the container without liability of injury. to the operator, and yet which remains intact for replacement for resealing the container.

Other objects and advantages of the invention will be apparentto those skilled in the art, from the following detailed description,

when taken inv connection with the accom-n panying drawing; in which Figure 1 is a vertical sectional view of the cap closure; and l f Figure?, is a side elevational view of a glass jar with the improved finish; the neck of the jar being partly broken away to show the finish in section'.

Referring to lthe drawingmore in detail,

.the numeral 1\ indicates a portion of a glass container, which may or may not be provided with the usual beading 2, as desired. The finish of the glass container includes a plurality of knobs around the mouth of the container in spaced relation and at a slight distance below the mouth thereof. The number, size andv shape of the knobs or'studs, as well as their spacing are variable, depending upon the size of the container, the holding power desired, the gauge of cap metal, etc. i

The cap is indicated enerally by the numeral 4, and may be ma e of any of the common metals, such as tin plate, zinc, iron, steel or aluminum. The top of the cap is prefer'- ably provided withan annular seat 5 to receive the sealing compo 6; but it is to be understood that the cap may be equally well designed as a side seal. In embodying the 1nor studs 3 which are arrangedve'ntion in a cap of the side seal type, the annular seat for the sealing material is formed in the skirt instead of in the top of the cap as illustrated in the preferred form of construction.' And while I have illustrated, and Vprefer to use, a compo sealing medium, yet the seal may obviously be made by rubber gaskets gbr rings, or by a liner ofy pulp and oil paper, etc., and the invention contemplates the use of any desirable sealing medium.

The skirt of the cap is provided with a continuous annular beading, which presents an internal groove 7. This internal 'annular groove is arranged at the proper distance -from the top of the cap, so that when the cap 1s in sealing position the groove will engage over the knobs or studs 3.

The bottom ot the skirt is provided with an outward roll or bead 8, to facilitate the insertion of a, removing tool, and to eliminate the liability of cutting the operator.

The manner of applying and removing the cap Will now be briefly described.

In view of the fact that the cap has a continuous cylindrical skirt, it will be fairly rigid,eand hence it would be practically impossible to stretch it over a continuous bead finish of slightly greater diameter, i. e., of a diameter sufficiently large to cause a gripping action with the cap. However, by the use of the finish disclosed herein, comprising a plurality of knobs or studs with intervening spaces', lthe skirt is distorted and iattened out tangentially between the knobs, and hence can be forced over the knobs with comparative ease, due to the increased diameter of the skirt at the points of engagement with the knobs.

This distortion of the cylindrical skirt, together with whatever stretch occurs, results in a clamping action; the lower wall of the annular groove clamping over the spaced' knobs, and thereby securely fastening the cap i i hasvbeen once removed it will be stretched sufficiently to permit an easy reseal to be made by manual pressure. l By reason of the fact that the locking 5 groove 7 is continuous, the cap does not have to be placed on the container in any particular position relating to the knobs or studs 3. This facilitates the sealing; and when the caps are to be employed in vacuum sealing it permits the use of the present vacuumizers. i

While the cap and glass' finish have been described herem in considerable detail, it will be understood that various changes and modifications may be made Without departing from the spirit of the invention, and the appended claims are intended' to be of such scope as to cover allsuch changes or modifications.

What I claim is 1. In combination, a glass container, a plurality of integral knobs widely spaced about the mouth of the container, a cap having a depending skirt, said skirt provided with a continuous internal groove spaced from the lower edge thereof, said cap seated on the mouth of the jar with the groove engaging over said knobs.

2. In combination, a metallic. cap having I an annular seat adapted to receive a sealing 3o medium, the skirt of said cap provided with a continuous annular internal groove spaced from the lower edge ofthe skirt, a glass container, knobs Widely spaced about the mouth of the container and formed `integral with the container, said knobs being below the mouth ofthe container a sufficient distance to cooperate with the continuous groove, when the cap is in sealing position.

3. In combination, a metallic cap having 40 inl its top an annular seat adapted to receive a sealin composition, the skirt of said cap provided with a continuous annular internal groove, the bottom of the skirt having an outwardly rolled edge, a glass container, widely s aced knobsA having curved surfaces arrange about the mouth of the container and formed integral with thecontainer, said knobs being below the mouth of the container a sufcient distance to cooperate with the continuous groove, when the cap is in sealing position.
