UNITED STATES PATENT OFFICE.
CHARLES HAMMER, OF BROOKLYN, NEW YORK, ASSIGNOR TO AMERICAN METAL CAP COMPANY, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.
METAL CAP.
Specification of Letters Patent.
. Patented Mar. 30, 1920.
To all whom it may concern -Be it known that I. CHARLES HAMMER, a citizen of the United States, residing in Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Metal Caps, of which the following-is a specification.
This invention relates to metal caps of the type formed with a flange which is intended to be forced onto a jar by downward pres sure alone and held thereon by friction. with or without a vacuum.
The object of the invention is to improve and simplify the construction of such caps 15' well as to increase their effectiveness in use.
\Vith the foregoing and other objects in view, which will appear as the description proceeds. the invention resides in the arrangement of parts and the details of construction hereinafter described and claimed, it being understood that changes in the embodiment of the invention herein disclosed can be made within the scope of what is claimed. and as indicated in the variations of the claims without departing from the spirit of the invention.
In the accompanying drawing forming part of this specification Figure l is a view in section of part of a jar and cap before the cap is pressed down onto the jar.
Fig. 2 is a view the same as Fig. 1 after the cap has been pressed home.
Fig. 3 is a view similar to Fig. 1 of the cap when employed with a sealing ring,
Fig. l is a view similar to Fig. 2 showing thecap and seal when pressed down on the vessel.
Fig. 5 is a plan view of the improved cap.
Like reference numerals indicate corresponding parts in the different figures of the drawing.
The reference numeral 1 indicates the upper end of a glass or jar formed with a substantially straight outer wall 2 and an upper edge formed with a downwardly and outwardly inclined wall or corner 3.
The metallic cap is formed with top 4 having therein a centrally located depression 5. The cap is also formed with a downwardly extending annular flange designed to surround and frictionally engage the wall 2 of the glass 1. The annular flange of the cap isi'ormed below the top 4 with a substantially straight inwardly inclined or contracted portion 6. Below the inward inchne 6 is an outwardly inclined or flared poi" tion 7 which is slightly curved and terminates at its lower end in a bead or curl 8. Disposed between and connecting the lower portion of the outward incline 7 is an inward curve 9 formed on a substantial arc.
The proportions of the cap and jar preferably are such that when the cap is loosely placed on the jar the inclined outer corner 3 of the jar supports the cap by contact with the upper portion of the outer incline 7 at the point where it merges into the inward curve 9. By applying pressure straight downward on the cap, it is forced from the position shown in Fig. 1 to that illustrated in Fig. 2. The cap remains in place on the jar by frictional engagement with the wall 2 either with or without. the assistance of a vacuum.
When it is desired further to seal the jar a sealing mag 10 as shown in Figs. 3 and 4 is employed. This sealing ring at its lower edge engages the juncture of the inward curve 9 and the inward incline 6, and at its upper edge touches on an incline the top 4 of the cap. When the cap is pressed home. the sealing ring assumes a position such as is shown 1n Fig. 4.
The improvements of the present invention are strong, simple, durable and inexpensive in construction and thoroughly cflicient in action.
What is claimed as new is:
1. A friction closure comprising a top having an annular flange formed with an inward incline, an outward incline below the inward incline and an inward curve connecting the inward and outward inclines.
2. A friction closure comprising a top having an annular flange formed with a substantially straight inward incline. a slightly curved outward incline, and an inward curve on a considerable are connecting the inward and outward inclines.
3. A friction closure comprising a top having an annular flange formed with a sale stantially straight inward incline, a slightly curved outward incline, and an inward curve on a considerable are connecting the inward and outward inclines, there being a head on the lower edge of the outward incline and a depression in said top.
4. The combination of a jar having a Sillr stantially straight outer wall with a downwardly and outwardl inclined portion at the upper end thereo of a cap having an annular flange formed with an inward incline, an outward incline below the inward incline, and an inward curve connecting said inclines, the proportions of such jar and cap being such t at the downward and outward incline of the jar enga es the juncture of the outward incline an the inward curve when the cap is applied loosely to the jar.
' 5. A closure comprisin a top havingan annular flange formed with an inward incline, and an inward curve below said in- 15 ward incline.
6. A closure comprising a top having an annular flange formed with an inward incline, an inward curve below said incline, and a sealing ring arranged at an angle to the perpendicular and bearing on said curve at its lower edge.
7. A closure comprising a top having a flange formed with a straight inward ineline, an outward incline therebelow, an inward curve between said inclines and a sealing ring hearing at its lower end against said curve and at its upper end extending inwardly at an incline to a contact with said top.
