Certain products generally packed in ;con tainers such as pails and buckets, must; from their ,nature, be sealed against the atmos= phere ,Qne sucn. product .is a. lard sul )st i1- 5.; tute comprising homogenized vegetable.

lt ha been t e practice to dispense such products in sealed pails and :the ultimate consumer would cut out the lid of the. container w ith a e'anopener or .the 1ike ,.,where,- fore the container, because of such mutilationand because of the resultant sharp edges leitI-on the container, could not-be utilized except with extreme care and-,only at such great risk of physical injury that generally such containers were thrown away. These containers, ii they'were usable, were very desirableto the po'orenclasses, yet, for the reasonsstated, the use thereof was generally dispensed with. 1 A An object of our invention is to provide means for..,se alinga smooth edged. vessel .or

. container, so that after the seal, is broken and the container is emptied, the container ma be used for the ,same purposes for wh ch similar unsealed containers are used.

Anotherobject of our invention is to provide simple and efiicient means for accomplishin the purpose stated.

Anot er object is to provide a means for the purpose stated that is economical of production and application.

Another object is to provide means that may be readily detached from the container without the employment of special instruments and without mutilating the container.

Another object of our invention is to rovide a device wherein the likelihood o injury to one opening the container is reduced to a minimum.

. These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which:

Fig. 1 is a side elevation of a pail having mounted on it a lid or closure togetherwith sealing means, all of which form details of our invention.

Fig. 2 is a plan view of'the device shown in Fig. 1. a

Fig. 3 isan enlarged fragmental sectional view on line 3-3'of Fig. 2.

Fig. 4 is an enlarged fragmental view of the disclosure in Fig. 3. n

Fig. 5 is a plan view of a lid-forming a detail of our invention.

Figs. 7,8; 9iandi 1 0 are plan views similar to Fig; 2' and showing; the steps incident to removal or: a. lid v and seal ingrring from a pailsuch as is shownin. Fig; 1.

The pail? 20 is provided at its upper end. with. an outwardly turned head 21-, whereby to provide asmooth unobstructed inner surface 22% of the ail affording no: inaccessible crevice or the ike in which anythin may lodge and therefore permitting rea y and easy cleansing of the inside of the pail; A lid 23; provided with an annular U-shaped oove' or ledge 24, is adapted to closethe mouthof the pail, the groove assuming an inverted position and adapted to receivev the head 21. Preferably the groove carries a sealing compound 25, for example, a solution of ben'zolv and rubber, or latex or sap of rubber tree dissolved in aqua ammonia,

21 for securely clamping the sealing ring and the lid upon the bead 21. The lid and locking ring are applied under pressure. The looking. ring comprises a radially extending tearing tabv 29' provided with an aperture 30. At opposite sides of the tearing tab 29 the locking ring is cut away to provide inwardl diverging slots 31 and 32. The outer e ges of the slots 31 and 32 are disposed adjacent the upwardly formed bead 33 of the locking ring, the inner face of which bead defines the groove 27 in the locking ring. The inner annular edge 34 of the locking rin is bent slightly in relation to the interme iate portion or body 35 of the locking ring so that an annular flange is provided that. yieldingly engages upon the upper face 36 of the lid 23, the engagement being at the extreme inner edge of the annular flangeand entirely around the flange, the contact between the flange and the lid being annulan.

It: is readily apparentv by reference to Figs. 3 and 4 thatv the application of the lid and lockingringto thepail, under pressure, serves to seat: and retain. the sealing outer annular ed e 28' of the sealing rim is adapted to be 10 ged under the bee compound between the ring and the pail so as to seal the contents thereof.

When the ail is to be opened, an ice pick or the like 37 has its point inserted through the aperture 30, see Fig. 7. The ice pick is projected through the opening, until the point thereof may be brought into engagement upon the ocking ring at some distance from the tab 29, for example as shown in Fig. 8. In order to accom lish this, the ice pick should be inserted rom the outsideas shown in Fig. 7, and the tab should be twisted upwardly as disclosed in Figs. 8 and 9. When the point of the ice pick rests upon the sealing ring as shown in Fig. 2, the handle is lifted thereby transversely tearing the sealing ring as disclosed in Fig. 9. The weakening of the sealing ring by provision of the inwardly diverging slots 31 and 32 assures a transverse tearing of the tab so that after the ring has been torn or severed as shown in F ig.

lid by bringing same to bear upon the outer Occasionally the" annular edge of the lid at the junction Presthereof with the bead on the pail. sure directed upon the lid at the said point will eilectively and expeditiously loosen the lid from the pail.

It will be not-edthat the engagement of the yielding flange of the ring on the top or lidprecludes injury that occasional raw edges on the ring might inflict on persons who may handle the pail.

What we claim is: I

1. The combination with a can having a lid beaded to the rim of the can and having an annular depression adjacent said bead, of a sheet-metal sealing-rin having its outer edge beaded over the lidead and its inner resilient portion extending across-saidde.

pression and having its extreme circular edge bearing down resiliently on 'thetop face of the lid.

2. The combination with a can having a lid beaded to the rim of said can, of a sealing-rin having its outer edge beaded over the lidead and its inner circular part extended inwardly to form an annular flange bearing down on the top face of the lid, the edge of said flange being provided with spaced notches'forming between them a tab, said notches terminating short of the aforesaid bead.

In testimony whereof, we have hereunto subscribed ournames this 30th day of J anuary, 1925.
