* Fig. G-is a view-showing thablank from which the end closure-is formed.

Fig. 7 is a fragmentary view illustratingzthe manner of opening the-container:by tearing out the tear strip.

- Fig. 8 is anenlarged sctional-view on the I indicates the container body which may .be

of any suitable material but-which will: prefer- I ably be of glass-or -=-possibly -plasticmaterial.

This container body isshown ashaving; a relatively short neck-portion 2 atits-upper;end which provides the opening 3 through which the .con-

tainer is filleda-nd throughwhich-thecentents thereof are discharged.

' The neck 2 is provided at its top-with anexterior bead havinga "cylindrical-side' wall, the under side of. which bead provides a downwardly faoing'shoulder' 4'which is situated a short distance below the top of the neck.

The end closure by which the container is sealed is indicated generally at 5, and it is preferably made of sheet metal. Said end closure is formed with a depending cylindrical skirt portion 6 which encircles and tightly fits the part of the neck above the shoulder 4, the lower edge of the skirt portion being crimped inwardly beneath the shoulder 4 as shown at I.

In order to provide an hermetic seal for the container, I preferably employ a sealing gasket 9 between the top edge of the neck 2 and the closure member 5, and the central portion of the closure member may be depressed so as to provide the channel 8 to receive the packing 9, this and which has itslerigthdimension, that is, the

being a common expedientincontainers of this 'The container .isv constructed .to,.,be; opened .by tearing out a tear strip ..from,the.,end ,closureli, andfor this purpose; the;.s kirt,portion'6.o.the end closure is providedwitha.scoreline vi 0. which extends completely; arqund the skirt at a point slightly above the-shoulder 4.

The end closure ,is.;also provided witlra. tab 1 I i which is, formed integrally. with. the closure dimension fromitstipto its, ,base.-where it, joins .the skirt ,portion,, ektending parallelto the lower edge of theskirt, said tabgqbeingspaced,,from

. s lower ed e of th s irtnortion as hown at l2. The end. closure is further providedwith a branch scoreline l3 which .ext,ends from the encircling scorelinel0..to,.the,edge of the inturned portion- I. at.a..point. .wh ere the upper edge of the tabmeets, said edge.

The blank fromv which theend closure ismade is shownat 5min Fig.v 5. @Thisyblank-iscircular inshape; and has-the tab. l l...integral therewith.

The blank is also formed with the circular, scoreline 1 ll ,and'with the. branch, scoreline. l 3 which extends .from thescoreline l0 to the edgeof the blankat the-point where thetupper edge of the tab meets the edgeef the blank.

After- ;the blank 5a,- has .been .blanked out .from

the" sheet metaland the-tscorelines l0 and I3 have been'formedfin -the blank .then said blank :is deformed by .meanspf dies,:to produce. the

\ end closure such.as;, shown..in. -Fig.. 2. which is provided with the depending skirtb. The dotted line; Ilin 6;indi cat es;-where; the.blank 5a .is.,.=bent to form;.-;the ;skirtpportion ofthe end closure.

The end clos reth s firmed xt e y p d .on the container asvshown in lfig. 3, saidcontainer having previously been provided with the packing material 9, and the end closure is sealed to the container body by crimping the lower edge of the skirt inwardly beneath the shoulder v lower marginal edge portion of the skirt underneath the shoulder as shown at I but it also bends the root portion l8 of the tab inwardly under said shoulder. This crimping operation brings the tab l I underneath the shoulder 4 and into a position where it lies flatly against the outside of the container neck 2 and has its length dimlinsion extending circumferentially of said neo The encircling scoreline I0 is situated slightly above the shoulder 4, and the upper portion of the branch scoreline l3 will extend from the scoreline ID to the shoulder 4 as shown in Fig. 1 while the lower portion of said branch scoreline [3 will be in the portion of the skirt which is crimped in under the shoulder 4 as shown in Fig. 4.

The advantage of spacing the tab H from the lower edge of the skirt portion as shown at I2 is that said tab will be below and out of .the path of the crimping wheel which is used for crimping the edge I of the skirt underneath the shoulder 4, and, therefore, said tab will not be distorted in any way bysaid crimping operation. I

This crimping operation, however, will force the tab into engagement with the exterior of the neck 2 so that the tab will lie closely against said neck and 'will be situated entirely beneath the shoulder 4. The tab is thereby protected by the shoulder, which is an advantage because it eliminates danger that the tab may he accidentally bent outwardly from the position shown in Fig. 4 during the handling or transportation of the sealed container.

This tab construction has the further advantage thatit enables the container to be opened by a key element I4 of the usual type which is provided with a tab-receiving slot l5. To open the container, the free end of the tab l I will be separated from the neck of the container as shown by dotted lines in Figs. 2 and 4 and then the key M, while held in position substantially parallel to the container axis, is applied to said free" end of the tab and is turned to wind the tab thereon. When thetab is completely wound on the key then further turning movement of the key will operate to tear the skirt, first along the branch scoreline l3 and then along the circumferential scoreline I0 thereby to tear mi from will take place along the encircling scoreline l0. Since the tear strip includes the inwardly crimped edge portion 1 of the skirt 6, said tear strip will be curved transversely, and as it is wound up on the key into the roll Hi, the inner or concave face of the tear strip will be presented on the outside of the roll and each turn of the roll will thus be seated in the concave face of the preceding turn.

This is clearly indicated in Fig. 8. The advantage of this is that each turn of the roll IE will be properly positioned in the roll by the preceding turn and the roll will be built up on the key without any danger that the turns of the roll will slip sidewise thus causing a collapse of the roll.

It will be noted that the encircling scoreline I0 is located in the lower portion of the skirt 6. The advantage of this is that, after the tear strip l9 has been torn out for opening the can, the end closure will still have a skirt of suflicient depth to fit over the top of the container thereby making'it a'replaceable cover or closure.
