SCREW-TOP Fo sYRuP. AND OTHER CANS-I.
To all whom it may concern:
Be it known that 1, WILLIAM J. CHAMBERS, a citizen of the United States, residing in Ohicago, inthe county of Cook and State of Illinois, have-invented a new and useful Improvement in Screw- Tops for Syrup and other Cans, of which the following is a specification.
' My invention relates to screwcaps or screw-tops for cans.
Heretofore great difliculty has been. experienced in the practical operation of screwto s or screw-caps for closing syrup and 0t er cans containing sticky or gummy substances, owing to the screw-cap sticking fast and becoming very difficult to open or unscrew.
The object of my invention is to provide a screw-top can of ,a simple, strong, efficient, and durable construction which may be securely and tightly closed and which at the same time may be readily opened however fast or rigid the screw-cap may become stuck or fixed, and this without danger of breakage.
My invention consists in the means I employ to practically accomplish this object or result-that is to say, it consists, in connection with the screw top or nozzle, of a screwcap furnished with an upwardly-projecting peripheral rim having a roll or reinforcement at its upper edge and furnished with a slot to receive a nail, knife, or other implement serving as a lever to unscrew the cap. My invention also consists in the novel construction of parts and devices and in the novel combinations of arts and devices herein shown or describedi In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of a syrup or other screw-top can embodying my invention. Fi 2 is a top or plan view, and Fig. 3'is an e arged central vertical section.
In. the drawings, A represents the can or vessel havin an upper head a furnished with a screw-top having an inturned flange b to form a seat for the cork or packing disk O and. screw-threads b to receive a screw-cap D. The screw-cap D is furnished with integral annular flanges d d, which embrace between them the inturned flange f of'the upwardly-projecting rim F, thus securely and Specification of Letters Patent. Application filed May 16, 1906. Serial No. 260.894.
Patented Oct. 23,1906.
firmly attaching these two parts together. The upwardly-projecting rim F has a roll, fold,.or reinforcement f at'its upper edge, and this upwardly-projecting rim is provided with a diametricalslotf to receive a nail or knife or other implement to act as a lever in unscrewing the cap. The interengaging folds or flanges (1, (Z and f are preferably additionally locked together by teats or projection's d f formed at intervals therein, or, if desired, these interengaging flanges may be soldered together for additional or further security. 1
G is a sheet-metal disk or washer interposed between the cork or packing O and thescrew-cap D or its inturned flange d to pre- I vent the screw-cap stickin to the packing, and thus interfering with t e unscrewin ,of 70 the cap. The screw-cap or its-flan e is 7 preferably provided with an annular ead d to give a narrow bearing between the screwcap and the disk or washer G, and thus facilitate the unscrewing of the cap.
I claim 1. In a screw-top can, the combination with a screw-top, of ascrew-cap furnished with an upwardly-projecting annular rim having a hollow circular annular roll at its upper end and an inwardly-projecting annular flange at its lower end, an annular recess on theperiphery of the screw-top in which the' annular flange on said rim is clamped, said rim being provided with open slots through the same and across said hollow circular annular roll, dividing said roll into openended arch-like segments to serve as fulcrums for a lever in unscrewing the cap, substantially as specified.
2.- In a screw-top can, the combination with a screw-to of a screw-cap furnished with an upwar ly-projecting diametricallyslotted'rim to receive a lever for unscrewing the cap, said upwardly-projecting rim being 5 furnished with a roll or reinforcement at its upper edge, and said upwardly-projecting rim having an inturned flange at its lower end, and said screw-cap having flanges or folds embracing said upwardly-projecting flange on said rim, substantially as specified.
3. In a screw-top can, the combination with a screw-top, of'a screw-cap furnished with an upwar ly-projecting diametrically- Ice slotted rim to receive a lever for the cap, said upwardly-projecting rim havin an inturned flange at its lower end, and sai screw-cap having flanges or folds-embracing said upwardly-projectin flange on said rim, substantially as specifier? 4. In a screw-top can, the combination with a screw-top, of a screw-cap furnished with an upwardly-projecting diametricallyslotted rim to receive a lever for unscrewing the cap, said upwardly-projecting rim being furnished with a roll or reinforcement at its upper edge, and said upwardly-projecting rim having an inturned flan e at its lower end, said screw-cap having anges or folds embracing said upwardly-projecting flange on said rim, a cork or packin interposed be-' tween said screw-top and sai screw-cap, and a sheet-metal disk or washer interposed becap, substantially as specified.
5. In a screw-top can, the combination with a screw-top, of a screw-cap furnished with an upwardly-projecting diametricallyslotted rim to receive a lever for unscrewing the cap, said u wardly-projecting rim having an inturned flange at its lower end, sai screw-cap having flanges or folds embracing said upwardly-projecting flange in said rim, a 1
c'ork or packing interposed between said screw-top and said screw-cap, and a sheetmctal disk or washer interposed between said cork or packing and said screw-cap, substantially as specified.
