FRICTION-TOP CAN.
SPECIFICATION forming part of Letters Patent NOv 795,127, dated. July 18, 1905.
Application filed December 31,1904 SerialNo. 239,279.
To (bi/l whom it may concern:
Be it known that 1, JOHN G. HODGSON, aciti- Zen of the United States, residing in May wood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Friction-Top Cans, of which the following is a specification.
My invention relates to improvements in cans of the kind or class commonly known as friction-top cans, or cans which are designed to be opened and closed repeatedly as the contents are being used, and which have a top or head furnished with a friction-seat adapted to receive a friction or slightly-wedging cover that is forced into the seat to tightly close the can by the tight close metal-to-metal contact of the cover with the seat in the top or head of the can. In this kind or class of cans great difficulty has heretofore been experienced in producing a liquid-tight closure between the top and friction-cover, especially where the cans are filled with an extremelypermeable or fluid liquid, like turpentine, ben" Zin, &c.
The object of my invention isto provide a friction-top can of a simple, eflicient, durable, and economical construction which may be readily and repeatedly closed and sealed by simply forcing the cover in place and readily opened by simply prying off the friction-cover and which at the same time may be closed liquid-tight with certainty and reliability.
My invention consists in the means I employ to practically accomplish this object or result-that is to say, it consists in a can having a top or head furnished with the customary integral depending friction seat wall or flange to engage the cover and having outside of said friction seat-wall an annular channel or gutter serving as a seat for an elastic or spring acting member with which the frictioncover is provided, in combination with a friction-cover having an integral friction seat wall or flange tightly engaging the seat wall or flange of the can-top, and provided with a rim portion furnished with a rounded or reversely-curved depending spring-actingmember engaging the seat Wall or gutter of the can-top, the cover being also provided with a marginal folded rim to enable the frictioncover to be removed from the can. My invention also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown or described.
In the accompanying drawings, forming a part of this specification, Figure 1. is a central vertical section of a friction-top can embodying my invention. Fig. 2 is an enlarged detail section, and Fig. 3 is a similar section showing the friction-cover loosely in place before it is pressed home.
In the drawings, A represents the can-bod y, and C its bottom head, secured thereto by a folded or other seam 0.
B is the can-top secured to'the can-body by a soldered or other seam a. The top B has a marginal flange Z) for securing the same to the can-body and a raised bead or shoulder b to serve as a fulcrum in prying off the frictioncover D. The top B has an integral depending seat wall or flange b tightly engaging the corresponding seat Wall or flange (Z of the friction-cover D, these interengaging seatwalls b dbeing, preferably,slightly wedging or tapering and the seat-wall d of the cover being slightly larger in diameter than the seatwall 6 of the can-top to insure a firm and tight gripping or anchorage of the two together when the cover D is forcibly pressed or driven home in the can-top B.
The top B has two annular gutters or chan nels b 6* between its friction seat-wall b and its raised bead or shoulder b, the outer one 5 to give room for the insertion of a tool under the rim of the cover D for prying off the cover and the inner channel or gutter 6* to serve as a seat for the elastic or spring acting member on the friction-cover D.
The friction-cover D is provided at its marginal rim d with a folded flange d to serve as a shoulder in prying off the cover and also with a depending elastic or spring acting member d curved to fit the annular channel or gutter 6* of the can-top and formed by the parallel depending flanges or walls (Z d in the cover D. A curved flange or wall (Z6 unites the seat-wall (Z with the wall (Z and forms a raised bead or annular upwardly-projecting rib on the cover, so that this raised wall 5 will not contact with the annular bead b" be low of the can-top B, and thus act as a stop to prevent the proper seating or forcing home of the friction-cover D in the can-top B. The free space (Z between the cover D and can-top B adjacent to the friction seat walls or flanges d 5 thereof and formed by this annular head or wall (Z enables the spring or elastic contacting members d and 5* of the cover and can-top to act effectively in rendering the closure tight against the most permeable liquids without materially tending to loosen the cover or counteract or overcome the frictional grip or anchorage produced by the parallel and slightly-wedging friction seat walls or flanges b and d of the can-top and cover. The curved flange or Wall (Z on the cover preferably projects slightly above the rim cl of the cover when the cover is not applied to or pressed home on the can-top, so that when the cover is pressed or driven home the slightest upward spring of the elastic-acting member (Z against its seat (I on the can-top may thus bring the rim (Z flush or on a level with the rim or wall d. The upward pressure between the seat 6 and the elastic or spring acting member 6Z3 of the cover is, however, so slight in comparison with the iirm and secure gripping or anchorage together of the interengaging friction seat-walls 5 (Z of the can-top and cover that it produces no appreciable tendency to loosen the cover. while at the same time-producing and affording by its elastic or spring action a safe and reliable liquid-tight closure.
I claim 1. In a friction-top can, the combination with a top having a depending friction seat wall or flange and two channels between said seat-wall and its outer rim, of a friction-cover having a depending friction seat-wall and a depending annular spring-acting member fitting and engaging the inner channel of the can-to p, said friction-cover having a raised annular wall between its said spring-acting member and its said friction seat-wall and forming a free space between the cover and can-top intermediate of said engaging parts of the cover and can-top, substantially as specified.
2. In a friction can-top, the combination with a top having a friction scat-wall and an annular seat-gutter between said wall and the outer rim of the can-top, of a friction-cover having a friction seat-wall tightly engaging the seat-wall of the can-top, and provided with a rim portion furnished with a rounded or reversely-curved depending spring-acting member engaging the seat-gutter of the cantop, said friction-cover having a raised annular wall between its said spring-acting memher and its said friction seat-wall and forming a free space between the cover and cantop intermediate of said engaging parts of the cover and can-top, substantially as specified.
3. In a friction-top can, the combination with a top having a friction seat wall or flange and an annular seat-gutter between said Wall or flange and the outer rim of the cantop, of a friction-cover having a friction seatwall tightly engaging the seat-wall of the cantop, and provided with a rim portion furnished with a rounded or reversely-curved depending spring-acting member engaging the seat of the gutter of the can -top, said cover being also provided with a marginal folded rim to serve as a shoulder for removal of the cover, said friction-cover having a raised annular wall between its said springacting member and its said friction seat-wall and forming a free space between the cover and can-top intermediate of said engaging parts of the cover and can-top, substantially as specified.
4c. In a friction-top can, the combination with a top having a friction seat-wall and an annular seat-gutter between said wall and the outer rim of the can-top, of a friction-cover having a friction seat-wall tightly engaging the seat-wall of the can-top, and provided with a rim portion furnished with a rounded or reversely-curved depending spring-acting member engaging the seat-gutter of the cantop, said cover being also provided with a marginal folded rim to serve as a shoulder for removal of the cover, and said frictiontop being further provided with a second annular gutter to enable a prying instrument to be inserted under the folded rim of the cover, said friction-cover having a raised annular wall between its said spring-acting member and its said vfriction seat-wall and forming a free space between the cover and can-top intermediate of said engaging parts of the cover and can-top, substantially as specified.
