Sept. 14, 1937.
H. SPENGLER CLOSURE Filed Jan. 25, '19s? I I a1 INVENTOR.
m max/W thereof from the position of Figures 1 to 3 to In applying the cap of Figures 1 to 3 to the top of the can I6a, having the bead Ila, with a lower recess I8, a cylindrical die IS .with a bevelled-lower edge 20 may be: employed; As
shown in Figure 6, the bead Ila has an inwardly projecting portion 34 upon which the cork disk 13 is compressed.
The die I9 contains an actuating member 2I.
screwed at 22 into the threaded recess 23. The
cylindrical member I 9 also receives the coil spring 1 24 which presses down the fiat die member 25; The flat member 25 has an upstanding nipple 26,
whichis tapped and receives the bolt 21 having the head 28. The bolt passes through the opening 29 in the cup 23 and may reciprocate in said cup 23 andalso in the recess 30 in the end of the rod 2 I. r 1 q In operation, the capping die I 9. will come down and thebevel 20 will strike the extended fold .I2,,
collapsing the metal of the lower portion I3 the position of Figures 5 and 6.
In the meanwhile, the fiatelement 25 will-press down upon' the baselll and'the cork 34 holding I them in position upon the top of the bead Ila.
The-extension of the ridge I2 will automatically press the metal of --the lower skirt I3 into the recess I8 with the result, as shown in Figures 5 and 6, that the portions of metal indicated at I2" in'Figures 5 and 6 corresponding to the flattened ridge I2 will be firmly clamped on the outside of I the bead Ila, while the cork willbe depressed on the. upper portion of the bead Ila.
The attached cap, as showninFlgures 5 and6, is devoid of the sharp outstanding edge, has a relatively neat appearance and may be mostreadily applied by a capping die, such as indicated in Figure 4, with substantial rapidity by automatic machinery.
The'caps, as formed in Figures 1.to 3, may ordinarily have a maximum external diameter at the ridge, I2 of linches, and a maximum depth before placement'upon the bottle top of inch.
Regardless of the depth of the bead I14 and the location of the recess I8, the operation indicated in, Figure 4, with straightening out of the ridge I2 will cause the lower skirt I3 to collapse around thelower portion of the bead with the indentations and elevations I4, I5, being received intherecess I8. I ,7
It will be noted that the outside of the cap, as shown in Figures 5 and 6, after attachment will be substantially cylindrical and a prying or bottle opening tool may be inserted there below to lift the cap from thetop of the bottle.
The cap construction thus far described is fully disclosed andclaimed in the prior application, Serial No. 72,679. a I
The present application isparticularly directed to the indentations 50 of round contour, as best shown in'Figures 1 and 3, or of wedge shape con tour, as shown at 50' in Figure 7, the similarly functioning parts of Figure '7 beingindicated by the same numerals as in Figure3 primed.
As shown, these indentations or 50 break up the fold or'ridge I2 into a series of sections or segments with the result that the metal of such fold or ridge I2 may be more readily unfolded or expanded to grip the top of the can and to form a close seal around the top and side of the bead.
Particularly where delicate containers of thin glass or metal are employed, it is desirable to weaken the fold I2 in the manner indicated in the indentations 50 or 50' so that the force required by the die in the operation as shown in Figure 4 will be a minimum and will not result in any deformationor undue stress or strain upon the container.
As' shown, the indentations 50 and 50' are spaced apart by two of the indentations I4, but it is obvious that this spacing could be varied so that the indentations 50 might be spaced five, six or even oneof said indentations I5 or bulges I4.
'If desired, in forming the indentations 50 and 50, said indentations may be caused to constitute a continuation of the indentations I5.
In comparing the indentations 50 of Figure 3 with 50' of Figure 7, it has been found that sharper corners 15, as indicated in Figure 7, when deformed into the final shape, as shown in Figures 5 and 6 will result in hardening of the metal around the periphery of the skirt with the result that the hardened vertical streaks in the skirtoi' the final cap structure will assure a closure of maximum strength which will stand up over long periods of time. r
, Referring to Figure 6, it' will be noted that the top of the cap has been drawn down and over the lip Il so as to place the cork or flexiblesealing material B in tension .and. to force it into" the recess between the lip Il and the skirt of the cap,
said recess being indicated at in Figure 6, This tensioned cap construction is more fully shown and described in my copending application, Serial No. 122,630 filed January 27, 1937. 4
In Figure 8 is illustrated an alternative construction in which the bulge I2 extends over the entire upper portion of the skirt, said upper portion of the skirt being provided with vertical grooves or recesses 50 to enable more ready deformation and spreading of the bulge.
In Figure 8 similar functioning parts to those in Figures 1 to 3 are indicated by the same numerals provided with a superior "3.
It is apparent that the specific illustrations shown above have been given by way of illustration and not by way of limitation and that the structures above described are subject to' wide variation and modification without departing from the scope or intent of the invention, all of which variations and modifications are to be included within the scope of the present invention.
What is claimed is; V
1. A cup shaped cap for'applicationto cans and bottles provided with top beads and similar con-. tainers, said cap having a circular base, a skirt depending circularly from said base, a cylindrical pliable sealing disk inset against said base inside of said skirt, said skirt h'avinga corrugated orindented lower portion, a smooth cylindrical upper portion and an intermediate bulged'portion providing extra metal, said bulge being adapted to'be contracted and spread to extend said skirt to grip the side of the bead and force the corrugated portion tightly below the bead, said bulge being provided with a plurality of indentations to enable more readily contraction and spreadingthereof.
