FRECTEON==TP GANQ Specification of Letters Patent.
Patented Sept. 19, 1905.
Application filed May 10, 1905. Serial No. 259,667.
To all whom it may concern:
Be it known that we, JOHN M. YOUNG and CLARENCE M. SYMoNDs, citizens of the United States, residingin San Francisco, in the county of San Francisco and State of California, have invented a new and useful Improvement in Friction-Top'Cans, of which the following is a specification.
Our invention relates to improvements in friction-top cans or cans having a top or head with a large opening therein surrounded by a slightly-inclined or wedging annular flange constituting a friction-face and closed by a friction cap or cover having a corresponding slightly-inclined or wedging friction face or flange engaging the friction-face of the can top or head.
' The object of our invention is to provide a friction-top can of a simple, durable, and economical construction having, as usual in such cans, a removable cap or cover for openingand closing the can as the contents are being used and provided with a protective frangible seal adapted to bear the name or trade-mark of the manufacturer of the material in the can and which. protective seal will require to be broken or destroyed before the can can be opened, and thus guard against the can being again refilled with spurious or inferior goods and palmed ofi' under the original label on the can as genuine, and in which the frangible seal may be applied at the canfactory where the cans are manufactured to a seal-holder ring, adapted to be sealed'and irremovably secured to the can after it is filled by a friction-closure similar to that employed for sealing and securing the frictioncover itself in place.'
Our invention consists in the means we employ and herein shown anddescribed for practically accomplishing this object or result that is to say, it consists in a friction-top can having an annular top provided'with a large opening therein surrounded by a depending flange, a frangible-seal-carrying friction-fit ring fitting within said annular can-top and provided with a fold embracing a frangible seal, a frangible seal carried by said ring, and w a friction top or cover fitting within said ring.
It also consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described, and specifically set forth in the claims.
In the accompanying drawings, forming a part of this specification, Figure l is a vertical sectional view of a can embodying our invention. Fig. 2 is a top oigplan view. Fig. 3 is a top or plan view with the friction cap or cover removed, and Fig-t is an enlarged sectional view. I
In the drawings, A represents the can-body, the same being of any suitable kind or form.
B is the friction top or head of the can, having a large opening B therein surrounded by a depending annular flange 5. The annular top or head B has an outer annular seamingflange b, by which it is united by a seam a of any suitable kind to the can-body A. The seam a, as indicated in the drawings, is a crimped or rolled seam. The bottom head C of the can has a countersink C and seamingflange c, which is united to the lower end of the can-body by a seam to, this being also preferably a rolled or crimped seam, although any other suitable form of seam may be employed. The annular can-top B, in addition to the depending or downwardly-projecting annular flange b, is furnished with an outer marginal channel or groove 6 and with an outer depending or downwardly-projecting flange b and with a horizontal flange 6*, said flanges b 5* forming an annular depending flange b.
D is an annular friction-fit irremovable sheet-metal ring having a horizontal flange d, the outer edge or rim of which is adapted to rest snugly against and tightly engage the .annular flange of the top B and form a tight snug fit therewith. The ring D has a depending flange or portion (1, the outer face of which is adapted to tightly fit and snugly engage the inner face of the depending flange 6 of the can-top B when the ring D is forced under great pressure into the can-top B, this being ordinarily done after thecan is filled in the same manner that the ordinary friction cover is forcedinto the ordinary friction-top can to close the same; but the friction-fit ring D is thus irremovably secured to the can-top B, as its horizontal flange d fits snugly within the annular flange 6 of the can-top, so that no leverage or other means is afiorded for removing or prying off the friction-fit frangibleseal-carrying ring D. The inner face of the -depending flange or portion (1 of the ring D' frangible's'eal in its bearing or carrying ring D. The frangible seal or carrying-ring D is preferably furnished with a marginal fold d at its extreme inner edge to give a smoothedged opening into the can when the frangible seal is cut-out or removed.
The friction cap or cover F has a somewhat deep countersink F therein, forming a depending annular flange f nearly upright, but preferably slightly wedging or inclined, and the. outer face f of which constitutes the friction-face of the cover that engages the corresponding friction-face d of the annular depending flange dof the ring D, thus forming a liquid-tight closure between said cap or cover F and the frangible-seal-bearing ring D when the cap or cover F is forcibly pressed home in said ring D. The friction cap or cover F is provided with a folded flange f at its rim to strengthen and stiffen the same and give ita smooth edge or rim. The folded flange f at the rim of the cover F also affords a shoulder for engagement with a lever or tool used in prying off the cover for opening the can.
At the can-factory where the cans are manufactured the frangible seal E is first clamped and fixedly secured to its carrying-ring D. After the can is filled this ring D is driven or forced under great pressure into the can-top B and these two parts so tightly and firmly secured together that they cannot afterward be separated and forming a liquid-tight joint by the extremely tight fit between the two and connectimgthe same. The friction cover or cap F is then ver'y tightlyforced into the frangible-sealcarrying ring D, thus forming a liquid-tight joint between the two by the close tight elastic grip between the friction or interengaging faces f 01 of the flanges f d, and as the elastic gripping or friction faces of the cover F and ring'D are slightly wedging or inclined the act of forcing the cover F into the ring D operates very firmly to clamp the ring D between the cover F and the can-- top B, thus giving still further security and tightness to both the joint between the ring D and top Band to the joint between the cover F and ring D. The intermediate ring D in a sense acts somewhat as a packing between the somewhat elastic depending flange f of the cover F and produces a closure which is exceedingly tight, safe, and reliable. The customer or packer in closing or sealing our improved can thus has two friction-closure operations to perform -first, that of seating the friction-closure frangible-seal-bcaring ring I), in place in the can-top B and then the seating of the friction-cover F within the ring D; but both these operations or closures are very simply and easily performed. Our improved can thus has a double-friction closure.
If desired, the parts D, E, and F may be as sembled at the can-factory, so that the packer or customer after the can has been filled may close or seal it by simply pressing or forcing the assembled parts D, E, and F within the can-top B in the same manner as is done in the ordinary friction-top-can closure. In our invention also the parts B, D, E, and F may, if desired, be all assembled together at the can-factory and the part B seamed to the canbody A after the can is filled, or, if preferred, the part B may be secured to the can at the factory and the can filled through its lower end, the bottom head C in such case being seamed to the can-body after the can is filled. We, however, prefer to practice our invention in the manner first described and wherein both the friction-fitring D and the friction-cover F are appliedafter the can is filled.
When the purchaser or user desires to open the can, this is done by simply prying off the friction cap or cover F, as is customary in cans of the kind to which our invention relates. After the cover F is thus removed the frangible seal E, which is preferably of paper,
may then be removed by breaking, tearing, .or cutting it out.
As the frangible seal E cannot be replaced after being once cut out or broken, the can is incapable of use a second time without detection by refilling it with spurious goods, thus affording ample protection to the original packer of the can against fraud. K
The frangible paper seal E may have printed thereon the name or trade-mark E of the packer whose goods are in the can.
To more firmly secure the frangible seal in place after being clamped between its carrying-ring D and the clamping-fold (V, we preferably form holding teats or projections d in the ring D.
We claim- 1. The non-refillable friction-top can herein shown and described, and comprising, in combination, a body A, a top or head B seamed to said body, and having a depending annular flange'b, downward flange and horizontal flange b, a frangible-seal-carrying irremov able friction-fit ring D, having horizontal flange d, and annular depending friction-fit flange or wall d, and provided with an integral fold 01 a frangible seal embraced by said integral fold in said ring D, and a friction cap or cover F having a-friction flange or wall f engaging the flange or wall d of said ring D, substantially as specified.
