Applicationmled. January 29, 1306. kSerial No. 298,546.

To all whom it may concern: d

Be it known that I, ROBERT M. WnrrsoN, a citizen of the United States of America, and residing at Chicago, in the county of Cook, State of Illinois, have invented a new and useful Closure for Vessels, of which the following is a specification. n

My invention relates to certain new and useful improvements in closures forl vessels and is designed to furnish means for hermetically sealing vessels, such as jars, lbottles, crocks or other 'containers, which closure is provided with a device for disrupting the seal to open the vessel,

The invention is further designed to furnish means for securely attaching to the cover of the vessel, the disrupting means, so

as to facilitate the handling of the parts in assemblingthe same. Y Y

The invention further designs toff'urnish means to prevent fragments of the disrupted seal fromaccidentally falling into the contents of the jar.

To such end this invention consists in cer'- tain novel features of construction, a description of which will be found in the followingv specification and the essential features of which will be more definitely set forth in the appended claims. i

The invention is clearly illustrated4 in the drawings furnished herewith in which- Figure 1 is a plan view of a vessel containing my improved closure. Fig. 2 is a central, vertical section thereof. Fig. 3is a perspective view of the wire loop that forms the means for disrupting the seal, and Fig. 4 is a perspective view of the cover. -V

Referring to these drawings 10,'represents a vessel here shown as a jar, and 20, represents the cover that is arranged to closethe open end thereof. The open end or neck of the jar contains an annular groove 11, below ed to receive and hold athin disk 30, of cardboard, paper or the like. The cover 20, is provided with a knob 2.1, centrally located,

and extending abovea central depression 22,V

formed in the upper face of the cover, the upper face of the knob being practically fiush with the highestpoint of the cover and its side tapering. down to the cover. Acircum-V ferential groove 23, is formed in the periphery ofthe cover, which groove is adapted. to receive and hold'a `Wire loop 41, that forms part of the seal disrupting device 40. As

shown the loop 41 of the disrupting device is in the form of an open ended ring, one end of which is bent upward and inward towardthe center of the loop portion, as at 42, Where it is bent into the form of a ring 43, which when the disrupting device is applied to the cover, encircles the knob 21. The ring 43 is preferably somewhat less in diameter than the greatest diameter of the knob, so that it may be forced past said part, and into the smaller part of the knob to secure it upon the knob and thereby prevent the ring from accidentally springing up and away from the knob. The advantage of an arrangement of this kind, is perfectly obvious. The end of the disrupting device is in a convenient osition to be grasped, and yet is so confined t at it is rout of the way so as not to interfere with the packing of the jars, and is not liable to become disengaged. The space between the edge of the cover and the neck of the jar is filled with a sealing substance, 50, as for instance paraflin, beeswax, plaster of paris, resin or the like, the loop 41 being completely embedded therein. The undercut groove 11 forms a seat for the sealing substance, and the latter not only hermetically 'seals the lcover to the jar but prevents its removal before the seal is broken.

Immediately below the Vcover is the disk 30, which is sprung into the groove by forcing it past the ridge or annular bead 13, that separates the two

grooves

11, 12. The disk 30, forms a sort of su plemental cover for the jar, and is provide for the purpose of preventing any of the fragments, of the broken seal, from falling into the interior of the jar.' This is especially desirable, since the vessel may be used to contain food stuifs, or other delicate substances where it is exceedingly important `to guard against Vthe entrance of foreign substances. which is asmaller annulargroove 12, adapt- Y the disrupting device 40 in place uV on it, is

then placed upon the annular bea or ridge 13, and the sealing substance poured into the annular space between the edge "of the cover and the neck of the jar, completely covering the wire loop, iilling the groove in the neck and extending slightly over the It will be perfectly obvious that the cover cannot become loosened from any ordinary handling or usage, but

that When the jar is to be opened the seal lnay be easily broken by simply removing the ring from the knob and drawing rprvard on the saine. 'ihe cover 2O can now be removed and any particles of the sealing material that may have fallen "cpon the disk, may be discharged therefrom. ihe disk 3U may then be pried away to expose the contents of the jar.

lt shot ld be noticed that the loop ai is placed in sich a position, that vvhen it is ptlled ort to break thc seal, the opening which it makes n ill permit the cover to be readily Withdrawn.
