Patented Mar. l5, 1932.
UNITED STATES PATENT ol-*FICE LINDSAY THORNE CRABBE, OF CHICAGO, ILLINOIS, ASSIGNOR TO PHOENIX-HERMETIC COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW YORK CLOSURE FOR JARS Application led June 26,
The invention relates to new and useful improvements in closures for jars or the like.
An object of the invention is to provide a metal cap having thread grooves in the skirt thereof and a bead at the lower end of the skirt, with a covering shell, the walls of which are smooth and can be decorated, and wherein the shell is firmly secured to the cap by a clamping engagement with the top of the cap and the beadat the lower edge of VFigure l is a view partly in side elevation and partly in section, showing the cap and the shell before the parts have been assembled and connected, and
Fig. 2 is a view similar to Fig. 1, but showing the shell attached to the. cap.
The invention has to do with a covering shell for a screw cap for bottles or jars. The screw cap includes a top portion and a depending skirt. The skirt is provided with a thread groove and a hollow outwardly rolled bead disposed at the lower edge thereof. The covering shell is made of metal and includes a top portion having a substantially horizontal annular peripheral flange adapted to engage the outer face of the top of the cap when the parts are assembled, The center portion of the top of the shell may be domeshaped. Said shell has a depending flange, the inner diameter of which is substantially the same as the outer diameter of the hollow' bead on the cap. When the shell is placed on the cap, thisidepending skirt extends downwardly outside of the bead, and the lower edge thereof isof such length that it maybe turned or bent underneath a portion of the bead for firmly clamping the cap against the horizontal annular portion in the top of the shell. Thus the parts are firmly locked together, so that the cap may be forcibly turned by gripping theshell.
Referring more in detail tothe drawings, the jarcap as shown includes a top portion 1 'having a depending skirt 2 which is provided with thread grooves 3. There may be ,a single thread groove or a plurality ofi thread grooves. Said thread groove terminates at the lower edge of the bead so as to .1931. serial No. 547,128.
receive cooperating threads on the jar. The lower edge of the skirt is rolled outwardly, thence upwardly and inwardly to form a bead 4. Disposed within the screw cap is a sealing pad or disk 5 which may be of the usual construction.
The invention is directed particularly to a covering shell for a screw cap. This covering shell includes a top having 'a horizontal annular peripheral portion 6, and as shown a domed portion 7. Said shell is provided with a skirt 8. The walls of the shell are smooth so that they may be decorated in any way desired. The skirt is'so proportioned it will bear firmly on the same directly above the skirt of the cap and the holding threads formed therein. The skirt 8 is cylindrical, y
and the inner diameter of the skirt is substantially thesame as the outer diameter of the bead 4. The shell is slipped down over the cap until the horizontal portion 6 comes in contact with the top of the cap. The cap and shell are firmly pressed together, and while so held. the lower edge portion 9 of the skirt 8 is bent underneath the bead 4 to a slight extent so as to .firmly grip the bead, and thus the cap is clamped between the top of the shell and this lower inturned edge portion of theskirt. The skirt is not turned under to any great extent, so that it does not project to the inside of the bead 4, and therefore, the bead L may be made with its internal diameter just sufficient to provide proper clearance for the threads on the jar to enter the screw cap. If the screw cap should be slightly out of round in the region of the threaded portion, due to the stresses incident to threading the same, it may readily reform itself to lit the threads of the jar without in any way disturbing the connection of Y the shell to the screw cap, as the portion of means for releasing the cap from the jar is the shell. The shell is grasped and turned, and through its connection with ythe cap, it f must turn the cap on to or off from the jar. Furthermore, the gripping of the cap is accomplished in the region of the skirt of the cap. The shell makes Contact with the upper face of the cap only to a limited extentin the region of the upper end of the threaded skirt of the cap. It also makes contact with the bead at the lower end of the skirt'of the cap, and thus it is that the cap is firmly clamped in the region of the skirt, and therefore, the clamping grip of the shell on thev capA is in the region of the threaded skirt which makes frictional Contact with the holding means on the neck of the jar.
From the above it will be apparent that I have provided a covering shell for a screw cap which is smooth and which can be decorated in any way desired in the Hat sheet, and the shaping of the shell to connect the same to the screw cap does not in any way 'disturb or destroy the decorated surface of the sheet.
- Furthermore, the shell when attached to the cap substantially covers and encloses the same so that there is no portionof the cap visible when the closure is attached to a jar. The shell may be decorated in any desired color throughout, and the whole closure will have the 'same color appearance of the shell.
It will be noted that the cap 1 is provided with a knurl 9 forming vertical corrugatio'n's which strengthen the cap in a vertical direction against collapsing when the shell is bumpedv or otherwise secured to the cap. Furthermore, the bead 4 at the lower end of the cap greatly strengthens the cap, :not only aiding in the attachment of the shell thereto, but it also strengthens the closure formed by the cap and attached shell.
Having thus described the invention, what I claim as new and desire to secure 'by Letters-Patent,is
1. A closure for jars comprising a metal cap having a depending skirtprovided with thread grooves adapted to engage cooperating threads on the jar, the lower edge of said skirt being rolled outwardly, upwardl and inwardly into a bead, a covering meta shell having a top and a skirt, said top being prof vided with a horizontal annular peripheral portion adapted to contact with the outer -face of the cap directly vover the skirt on said cap, the central portion of said top being dome-shaped, the skirt of said shell be ing cylindrical with the inner diameter thereofssubstantially the 'same as the outer diamat the lower edge of the of the Shell, the outer face of said shell being smooth throughout whereby the same 'may be decol being provided with a horizontal portion.
adapted to contact with the outer face vof the cap directly over the skirt on said cap, the skirt of said shell being cylindrical with the inner diameter thereof substantially the same as the outer diameter of the bead, said skirt extending below the bead 'and having the lower edge portion thereof bent underneath the outer portion of said bead and into firm gripping contact therewith, whereby said cap is firmly clamped between the horizontal portion in the top of the shell and the inturned portion at the lower edge of the skirt of the shell, the outer face of said shell being smooth throughout whereby the same may be decorated.
In testimony whereof, I affix my signature.
