CLOSURE.

- Application filed April as, 1922; Serial no. 556,691.

To all whom it may concern.

Be it known that I, NIXON LEE, a citizen of the United States, and a resident of the borough of Brooklyn, in the county of Kings and State of New York, have invented certain newv and useful Improvements in C- sures, of which the following is a specification, reference being made to the accompanying drawings, forming a part thereof.

My invention relates to closures used for sealing the openings in containers, jars or bottles in which the closure is adapted to be repeatedly applied to and removed from the container, and furthermore to tightly seal the container when the closure is aflixed and locked in sealing position, even after repeated applications and removals.

The objects of my invention are, among other things, to provide an improved closure structure of this type of container and closure whereby a more perfect seal and re-seal is secured for such improved closure; to provide a closure with a depending skirt portion and a plurality of inwardly extending lips to engage with radially projecting lugs on the container in which the leading edges of the lip portions shall be formed to engage with progressively increasing ressure the under surfaces of the lugs to raw down the closure upon the rim of the container openings.- Furthermore I also provide a novel stop end for each of the lips to coact with the lugs to limit the rotation of the closure in the-seating direction which 85 stop end at the same time tends to draw down the cap of the closure upon the rim of the container opening with a distributed, substantially uniform pressure, thereby furnishing an effective closure seal which can L be repeatedly used for rescaling the container opening after the closure has been initially removed.

With the above and other objects in view, my invention comprises the novel construetion, combination and arrangement of parts to be hereinafter specifically described and then particularly pointed out in the appended claims.

I attain the foregoing advantages b the closure shown in the accompanying raw in s in whichig. l is a side elevation of the glass container showing a preferred embodiment of my improved closure cap in dotted lines; Fig. 2 is an enlarged bottom plan view of the closure; Y

Fig. 3 is an enlarged detail view;

Fig. 4 is an enlarged fragmentary bottom direction of locking and sealing the closure;

Fi 8 is an enlarged perspective vlew showm in detail the construction of the stop en of the closure; and

Fig. 9 is an enlarged vertical sectional view showing the closure locked on the container mouth.

Similar numerals refer to similar parts throughout the several figures.

Referring more particularly to Figs. 1 and 2, the container 10 preferably formed of glass or other friable material, is of any referred shape or form, and has formed immediately below the mouth 11 on the exterior walls of the container a plurality of radially-projecting equally spaced-apart lugs 12, thenumber varying according to the size of the container. These lugs 12 have rounded ends 13' and a substantially flat horizontall disposed underrsurface let as shown in i 1 and 9 to formthe locking means for t e closure with the container; each rounded end .13 therefore provides a progressively projecting under edge to coact with the stop end of the inturned lips as-will hereinafter be described. I

The closure 15 proper is preferably formed of a resilient sheet-metaland comrises the circular top or cap'16 from which epends the annular skirt rtion'17 which 'is usually knurled. The skirt 17 has s aced the skirts and segmental in shape as shown in i apart inturned lips 18 integral wit Fig. 2, and somewhat longer than the lugs -panding 12. The leading end 19 of each of the lips 18 is substantially square and bent downwardly to form the inclined depressed portion 20 which is adapted to initially engage the rounded ends13 of the lugs when the closure 15 is preliminarilyrotated toward.

locking position as shown in Fig. 7.

' The stop end of the lips 18 is formed as shown in detail in Fig. 8 by bending the lip end to form the inclined fiace 21 and diagonally disposed brace 22, the face 21 being adapted to engage with the under outer edge of the rounded end 13 of the lug 12 to stop the rotating movement of the these stop faces 21 when pressed against the under corners of the lug ends 13, the edges of which are progressively projecting as shown in Fig. 4. I

The 0 eration of my improved closure is substantially as follows: The closure 15 is set on the container mouth 11 so that the lugs 12 are disposed between the several lips 1-8 with the lining or pack 23 restlng on the circular rim 24. Then this closure is twisted or horizontally rotated on the container mouth 11 so that the depressed ends 20 engage the leading ends 13 of the lugs 12 and guide the lips 18 to slide along the under surfaces 14, as shown in the righthand end of Fig. 7.. Then the continued rotation of the cap causes the several lips 18 to ride along the under surfaces 14 of the lugs 12 until the face 21 engages the under corner of the end 13 which stops the closure rotation. Then a fin' al twist given to the closure 15 will cause the faces 21 to slide into firm locking engagement with the under outer edges of the lugs 12 tending to slightly spread the skirt 17 outwardly as shown in Figs. 4 and 5. The tension in the skirt 17 resists such spreading and effectually prevents further rotation of the cap. The effect of such complementary spring action between the ca 16 and exskirt 17 is that the lining or pack 23 is firmly forced down and compressed on the rim 24 from points e ually spaced apart on the circumference o the closure, and provides a hermetic seal of uniform tightness throughout the annular seating of the closure.

It is manifest that my improved closure may be readily removed and afterwards replaced on the container to attain resealing, and that I have embodied in my container closure structural features which add to the effectiveness of the seal under different conditions of usage.
