PJst-o ce address is `519 Fifth street, in

seid city,) 'have invented certain new and useful Improvements in Bottle or ar Clo- Sires, of which the following is a specifica- +ron.

iMy invention has relation to bottles or j'irs and closures for the 'same in which the bbttle is preferably made of glass or other itaple material and the top or cap of thin ta In the use ofclosures of this kind difulties are 'encountered in `the formation the threads on the neck of the bottle or j r by means of which the cap is secured r moved into place, and further diiculies are encountered in centering the cap on *he bottle (which cap' should be preferably (.omparatively shallow in depth), and fur- -her difficulties are encountered in retainig the cap in place, and in applying it to e ar. lly invention has for its object to provide Q jar closure in which these diiiiculties are civercome; in which the thread on the neck of the bottle is easily and readily formed; `wherein the cap may be made of thin metal and of shallow depth; which may be readily placed in position on the jar without the tid of machinery, and retained firmly in olace during handling, nent; and which may be readily centered .lpon the jar-neck so that its movements upon the threads will be immediate and true, the latter avoiding uneven seating of the cap on the ar, leakage, and uncertalnty in the applicatlon and removal of the cap, which result from an ,imperfect or diicult centering of the cap on the`jar.

To this end my invention resides in the construction and combination of parts hereinafter described and further pointed out in the claims. p

In the drawing forming part of this specitication: Figure 1 is a plan view of the top of abottle or jar wit my improved cap attached. Fig. 2 is a side elevation of Fig. 1 showing a portion onl of the jar. Fig. 3 is a side elevation of t e neck and upper portion of the j ar showing the construction storage vand ship of the threads. Fig. 4 is an enlarged sectional elevation of a portion of the cap and jar the section being taken substantially on the line 4.-4, Fig. 2, looking in the direction of the arrows. Fig. 5 is a like view taken substantially on the line 5-5 of Fig. 2, looking in the direction of the arrows. Fig. 6 is a plan and section of the cap taken substantially on the line 6--6 Fig. 2, looking in the direction of the arrows.

drawing like reference characters, indicate similar parts.

The preferred embodiment of my invention is 'shown in the accompanying drawing.

1 is a bottle or jar having a neck 2. Upon this neck is formed an outwardly extendlng annular rib or projection 3 havingprefer ably a circularly inclined outer face 4; and above this a series of short interrupted screw threads 5 preferably having their greater diameter or thickness between their ends as at 6, terminating in the .sharpened ends 7, with the enlarged entrant and ter'- minal spaces 8, 9. Whlle the outer and u per surface -10 of these` threads may e curved upward toward the neck, I prefer that the lower surface be pl-ane as at 11, and that said lower surface Aof each of the threads form with the outer surface of the neck of the bottle substantially a right angle.

The cap 12 consists of an annular and dependent-flange 13 and aI crown or top 14 preferably made in one piece of metal, and which maybe very much thinner and lighter in construction than the usual cap closures are; and within the cap is placed a sheet of paper (or any other desired material) 15 for completing the seal which is formed when the crown of the cap forces the paper down upon the upper annular edge 16 of the neck of the bottle, as shown in Fig. 5.

In order to increase the grip of 'the hand upon the cap it may be provided with a series of projections 17.

near as possible to mio of the flange. They may be of any desired number corresponding with the number of interrupted threads on the neck of the jar, and may be located at any desired point about the vcircumference of the flange of the cap havingregard for their position relative to the openings 8 between the screw threads.

At suitable points along the flange of the cap I form pendant lips 20, which are pref-- erablyexpansive, and which depend from i the lower edge of the pendant fiange 13, and

preferably have a sllght flare outward, so

`. that the circle which takes in the inner edge made wider than the space between the threads so as to allow the lugs 18 to freely enter between threads 5 and that the inclined edge 19 of the lugs may, by a slight turn engage the lower edge `11 of the threads, so that by the conjoint action of these elements and the engagement of the flexible li s 20 with theinclined surface of the ann ar shoulder 3 the cap may be readily and accurately centered upon the jar neck.

The movement necessary to en age the crown of the cap with the top o the 'jar will, asis apparent from. the drawing, 'be comparatively slight, and during its turning movement the flexible lips 20 are making frictional contact with the annular shoulder 3 and are being continuously expanded or sprung outwardly the farther down the cap is moved; so that when the cap is moyed home the lips will be bearl ing with sufiicient relative -pressure on the' annular shoulder to prevent the inadvertent turning or release of thecap, but without suicient friction to form a substantial o position to the reverse 'movement of t e can, or in other words its intentional un 4 seating and removal; whlle at the same time the friction 'of the lips on the annular shoulder, tending to retard the downward movement of the cap, will tend to force the upper inclined edge 19 of the lugs 18 forcibly against the under surface 11 of the.

threads, thereby providing means for locking the lugs against the threads.

The result of the foregoing is that at the termination of the downward movement of lthe cap, or in other words its screwing on movement, the llps will bear upon the an,'

will at the same time constitute means for firmly locking the lugs and screw threads together, this locking being secured by the! action of friction of the lips 20 on the sur-l face of the shoulder 3, the friction causing; an upward pressure of the lugs 18 against-l the surface v11 of the threads 5, the inclina-l tion'of the lugs and the threads causingi the parts 6 to act in a direction laterally ofi the line of movement of the cap or sub-g stantially perpendicular to the bottle neck, the nearer the inclined lugs reach the`= loweri end of the threads and the rib 5, the greater; the friction, due to this action and the more firmly are the parts held together. Another@ function performed by the projections 20 is! that of centering the cap when it is appliedi to the bottle or jar. Then `these projections@ perform the very important function ofl centering the cap on the bottle in a manner' which facilitates the placing of the cap inl position; both with regard to centering andi with regard to the threads. i

If desired the lugs may be located directly'above the lips, and the projections 17 otherwise convenlently located upon the flange of the cap.; and other modifications; may be made in theembodiment of my im; vention which fall within the purview` ofil the claims appended hereto. g

Having described my invention, I claimzi 1. In a bottle or jar closure, the combinal tion of a capcomprising a crown and ag pendant annular flange, the bottle having a'E series of interrupted threads formed on its neck, lugs extending inwardly from the flange of the cap, a circumferential projection formed on the neck of the bottle, andi pendant freely resilient lips on the flangei of the cap adapted to engage said projection.

2. In a bottle or jar closure,l the combination of a cap comprising a crown and a; endant flange, lugs extending inwardly rom the flange of the cap, means on the: bottle or jar for engaging said lugs, a circumferential projection formed on the neck of the bottle, the lower edge of said flange being provided with projections extendingl below the ,lower edge of said flange, said "project-ions being freely resilient and adapti ed to resiliently engage the circumferential projection on the neck of the bottle.

3. In a bottle or jar closure, the combination of a cap comprising a crown and pendant annular flange, a bottle or jar having a project-ion thereon, threads on the neck of the bottle, lugs on'the flange of the cap and pro'ections on said flange between which said lugs are disposed, and resilient means carried by the cap flange adapted to cause 'said lugs to forcibly engage said threads by engagement with the said bottle or jar projection.

4. In a bottle or jar closure, the combination of a cap comprising a crown and pendf 1,025,375 y a ant annular vfiange, a bottle or jar having respect tothe engaging means on the bottle 10 a projection thereon, means for engaging or jar.
