My invention relates to caps or closure devices for jars and other receptacles.
An object of the invention is to provide a cap of the character indicated, designed to permit the use of a knife or other implement as a means for rotating the cap in attaching it to or removing it from the receptacle.
Other objects of-the invention will appear hereinafter.
In the accompanying drawing Fig. 1 is an elevation showing a cap constructed in accordance with my invention, applied to a jar, the latter being broken away. Fig. 2 is a top plan view of a cap and an implement in position for rotating the cap in removing it from or attaching it to a receptacle. i
Fig. 3 is a sectional elevation of the cap. Fig. 4 is a sectional elevation of a modified form of cap.
Referring to the accompanying drawing, I have shown a capor closure 5 which may be of usual construction, except as hereinafter particularly pointed out. As shown, the cap 26 is made of a single piece of sheet metal and comprises a top portion 6 and a dependlng flange or skirt 7 formed with screw threads to engage corresponding screw threads on the jar or receptacle 8 to which the cap 1s attached.
The lower margin of the skirt 7 is rolled, as 1s customary, to form a bead 9.
In accordance with the present invention,
the top portion 6 of the cap is formed with a pair of raised portions or bosses 1Q spaced 8 apart to provide a channel 11. The inner edges 12 of the bosses 10 form the side walls of the channel 11, said edges, as shown, being parallel and equally spaced from the center i of the ca 9 As shown inFig. 3, the side walls 4 12 are su tantiallyvertical.
The channel'11 is of suitable width to re ceive the blade of an ordinary table knife 13 which can thus be used as a lever for screwing the cap down tightly on the receptacle or for ti removing the cap. Any other smtable implelel with the top cover ment might be used in place of the knife 13.
The bosses 10 are preferably arranged symmetrically on opposite sides of the center of the cap, and the edges 12 are of considerable length so that if force is applied to the implei0 ment 13 for rotating'the cap, the pressure at the points of contact between the implement and cap is comparatively small, and any danger of mutilating either the cap or imple ment is avoided.
The walls 12 or edges, of the implement receiving channel 11 are exceptionally resistant to distortion under pressure of the cap rotating device because of the bosses being formed integral with and in their entirety raised N above the plane of the adjacent surfaces of the top coverportion. Such resistance is further enhanced by arranging at least a major 7 portion of the upper wall of each boss paralortion and at the upper margins of the e' ges 12 or walls, of the channel. The upstanding arcuate wall defining the outer margin of each bm also contributes materially in preventing collapse of the boss under pressure resulting from to 10 tative movement of the cap rotating implement.
Fig. 4 shows a modification in which the side walls 12 of the channel 11 are undercut or inclined in a manner to provide an overhanging lip or the like which prevents the; knife blade or other implement from acci dentally slipping out of place when'in use.
Modifications may be resorted to Within the spirit and scope of my invention.
A closure comprising in its entirety a single circular piece of sheet metal stamped to form a circular top portion, and a dependingscrew threaded attaching flange, said 88 topportion being formed with a pair of hollow bosses at opposite sides of its center," said bosses having a pair of opposed walls cooperating with each other and those areas of the top portion therebetween forming 90 a transverse channel adapted to receive a closure rotating implement, said opposed walls conver 'ng upwardly to facilitate holding the imp ement in the channel ainst 5 other than lengthwise movement an said bosses having a major portion of their upper surfaces arranged substantially parallel with the remaining areas of the top portion and in a plane thereabove.
Signed at Toledo, Ohio, this 27 day of August, 1932.
