CAN AND THE LIKE.

To all whom it may concern:

Be it known that I,'EUGENE L. GREENE- WALD, a citizen of the United States of America, and resident of Wilkinsburg, Pennsylvania, have invented certain ew and useful Im 'rovements in Cans andthe like, of which t e following is a specification.

My invention relates'to improvements in cans and the like which may be made of sheet metal or any other suitable material,

certain of the improvements being susceptible of use in the construction of cans of paper or other suitable material, and in the construction of closures for containers as will be hereinafter set forth.

Heretofore, in-the construction of cans and similar articles comprisinga body part and a cover part for the end of the body secured to the body part as to form a permanent joint between the body and its head. Such a construction precludes the easy-removal of the cover section,-in order to open the can it becomes necessary to cut or otherwise mutilate a part of the can, the cover part or body part or both.

Another objection to oining the cover to the body in the ordinary manner is that the drawing or working of the edge of the cover to form the depending flange which is bent and stretched to form theseal, causes an annular thinner and weakened section a slight distance within the edge of the cover part and at a point where more than elsewhere it is important to have the normal thickness and strength of metal or other material. In

other words, the material is stretched, and

if the metal of which the device is made is lacquered inthe sheet, or before the can is sealed, the .coating of lacquer or the like will crack when the cover is applied to the body. It is the object of this invention to overi come the foregoing and other objectionable features of certain types of cans and similar containers, so as to provide a can or the like to which the cover section is applied in a novel manner and'whereby the same may be readily opened by a simple manipulation and without mutilating, tearing, cutting or in any way rupturing the head or body of the same.

A further object is to apply the heador cover to the body and form a seam between Specification of Letters Patent; Patented Nov. 4%, 1919. Application filed November 7, 1913, Serial No. 799,641. Renewed February 13, 1918. Serial No. 216,976. I

being substantially coincident, the cover resting on the flange and if desired, a suitable gasket or sealing composition may be interposed between theflange and cover art.

The scaling is accomplished by radially corrugating1 the edges, or by folding or crimping t em so as to reduce the outer diameter of the same. The two edges are si multaneously bent to the same extent, to aposition alongside the body,the contiguous body part, the flange and outer edge of the cover part to a width substantially equal to' the width of the flange are thus disposleld.

substantially parallel to each other. 2-wall corrugated seam between the cover and body produces interfitting corrugations in the parts and serves toassist in locking the parts together and against relative rotary movement and has the veryimportant advantage that by suitable means the oorrugated edge of the cover may be bent out and when the said corrugations are shallower atseveral points the cover may be removed without a mutilation ofeither of the parts.

The coverpart may be a flat circular disk of metal or other suitable material and corresponds approximately to the diameter or outside dimensions-of the flange on the body part. When the cover part is joined to the grooved or flaring ended body-member by a corrugated seamand the flange and edge of the cover part are bent beneath the flare,

the plain disk suffices as a cover member and the parts are securelylocked together. In I the body of uniform section, the cover part is provided with. looking extensions or tabs constructed of flexible or other suitable materiaL' The tabs are bent in beneath the flange and when the corrugated seam is formed and the flange and edge of the cover are bent against the side of the body, certain tabs may be of such a length as to project from beneath; the parts forming the seam so that they may be engaged by means of a suitable device to assist in removing the cover. The tabs may be provided on the covers for the bodies having flaring ends, to augment the locking action and to provide means whereby the cover may be more readily loosened and removed. The metal or material of the body part may be nonyielding so that the corru ations will not sink into the material as tie parts do not depend on enterin or biting lnto the ma terial for their 100 ing function. The material of the can body and cover are not stretched when the parts 'are secured together and consequentlythe body part will be of uniform thickness throughout which is an advantage as it allows the container to be made of thinner material than heretofore. The entire can may therefore be formed and sealed without stretching any of the material thereof.

The objects and novel features of the inventionwill be-apparent from the following detail description, taken in connection with the drawings, in which Figure 1 is a perspective view of a can or container embodylng-lnv invention, the

Referring to Figs. 1 to 'l, of the drawings,

bottom respectively, the said flanges being formed on the body 20 in any suitable manner, but preferably so that the flanges and tubular part will be of the same thickness throughout. Circumferential V-shaped grooves or

depressions

23 and 24 are formed in the body 20 just within the flanges 21 and 22, respectively, the grooves thus forming the'flaring months or ends 25 and 26.

The cover part for thebottom of the can body comprises a metal disk 27 of a diameter substantially equal to-the diameter of the flange 22. and having its periphery substantially in coincidence with the periphery of the flange.

'The bottom 27 is secured to the can by crimping or corrugating and simultaneously bending both the flange 22 and the bottom 27. The corrugations formed are arranged non-concentrically and are deeper at the outer edge of the flange and bottom and as this corrugating operation reduces the actual circumference of both flange and bottom, the edges thereof may readily be bent toward theaxis of the can and into the groove 24 asthe corrugations gradually in-' crease in depth. When bending the flange and bottom into the groove a resilient headlike roll may be formed to assist in holding the bottom on. However, the extensive frictional contact between the bottom and the flange, ,and the fact that both extend inwardly into the groove 24 serves to effect a preferably provided with an approximately V-shaped annular groove 30, the wall 31 of which may which may be of an inclination .to conform to the flare of the portion 25 so that it will seat tightly on the latter and automatically center the cover part on the mouth of the can. The flaring end 25 provides an inner sealing shoulder part, and an outer shoulder beneath which the edge of the plate-like cover part may be corrugated and bent. It is to be understood that the entire center of the cover "part 29 may be depressed, leaving an inclined wall 32, as before, to fit tight against and center the said cover on the mouth of the body. The bead formed by the grooved portion also serves to reinforce the cover and enables the head of the can to resist greater side pressures thereon.

Beyond the groove 30 of the cover and concentric therewith, there is a groove 293 adapted to receive-and retain a suitable gasket or sealing composition 292. Preferably an albuminous or similar gasket is inserted in the groove 291- in a liquid state and allowed to solidify. A small soft rubber gasket may also be fitted in the groove. An annular bead 251 is formed at the upper edge of the flaring portion 25 of the body and is of such a size as to fit in the groove 291 and compress the gasket therein as shown in when the parts are seamed together to assist-in forming a hermetic seal. The head 251 comprises a portion of g the resilient bead formed atthe end of the can body when the cover is secured to the flange of the body part and bent down.

The edge or periphery of the cover part coincides with the periphery of the flange 21, as in the construction of the bottom.

' In addition, the cover has a series of spaced integral or attached, yielding extensions 01" The longer tabs may be bent upon themselves intermediate their ends, as indicated,

in dotted lines in Figs. 2 and 3, and then bent beneath the flange 21, the short tab 33 being also bent beneath the flange. The cover part 20 is thus locked to the body partby the

extensions

33, 34,,and 35,, but as the ends of the

extensions

34 and 35 project beyond the edge of the seam formed when the flange 21 and edge of the top 29 are .corrugated and bent into the groove 23, they be vertical, and the wall 32of for supporting the cover instrument and drawn outwardly. The lock which the extensions effect is thereby released and the corrugations orfolds in the cover part 29 may be drawn outwardly, thereby gradually increasing the diameter of the corrugated dependingnflange formed on tlie cover until it will ally slip over the beadlike roll 37 formed when the flange 21 is folded or corrugated and bent into the groove 23 with the cover part 29 locked thereto.- It is not necessary to force the extension 33 from beneath the inwardly extending seam. The said extension may serve as a hinge about which the cover may be turned'when it is raised off the can.

may be seized with the fingers or a suitable A gasket may be fitted about the inclined wall 32 of the groove 30 in the cover part 29 .or it may be arranged in a suitable groove in the flange 21 so as to form a more effective seal. -A suitable. sealing composition such as albumen, or thelike, may also be applied to the abutting faces of the flange and cover section to augment the-sealing action. The

flange 21 and edge of the cover part 29 may be crimped, folded or corru ated and simuI-J taneously bent'into the groove 23 alongside the can body, in the same manner as the bottom part 27 is aflixed to the body.

It is to be understood that looking "exten- ,sions may 'also be provided on the bottom part 27 or they may be entirely omitted from both bottom and top, if desired, the inherent properties of either the bottom or top holdingthe same in place on the body.

The can bod may be equipped with a bottom of the or inary or any preferredtype;

The can body may, furthermore, be made up with the bottom attached thereto and the flange 21 thereof corrugated and bent into the groove 23 before the lid 20 is applied thereto. In such a construction lockwith, the lid beingset on the mouth of the can so that the groove 30 coeperates to center the cover. To properly place the cover sec-- wing extensions for the lid may be dispensed tion, it may be provided with several spaced dents and the cover section mav be turned so that the dents-therein will register with certain corrugations on the' inturned body flange. To secure the-cover to the can, the cover is corrugated or crimped from its edge onto the head or roll 37 and simultaneously bent downwardly and into the groove 23,

forming. in effect a downwardly and inwardly turned corrugated flange on the cover 29, the corrugations 'thereof/- finally fitting into the corrugations of the flange 21.

The edges of the seams formed by the longitudinal corrugations may be of a slightly smaller diameter than the body portionof I the container and will, therefore, not be sub-- ject to any knocks which might accidentally .loosen the parts or destroy the seal.

, Referring to Fig. 4, the securing flange at i the mouth of the can body 201 comprises the roll flange or'bead 211 formed by rolling the flange so that the edge thereof will not be exposed. Heretofore it has been impossible to apply a seal of the crown type to a wide mouth container because the bead has been faulty in that it lacked resilience. A resilient bead is essential in order to get a hermetic seal with a large diametered core and such a bead is pro ided in the roll bead or flange 211. A resilient band may be se-.

cured to the can body or the bead may be folded instead of rolled, the essential feature being to. provide resiliency. The cover 38 has a depressed portion formed by the groove 301, the depressed portion resting on the inner bead 202 where an additional seal is had. The marginal edge of the'cover is rolled so that the raw edge of the cover will be unexposed and so as to form a resilient bead 381 of suflicient'resiliency to snap over the bead or flange 211. No locking tongues are reqliired as the bead 381 is sufliciently stifi' to hold the cover under the flange 211. The cover 38 may be corrugated as at 382 between the bead 381 and groove 301 to apply the same to the can body orit may be corrugated across the resilient bead as it is applied to the body to confine the edge of the cover beneath the resilient flange 211. The cover may be lifted ofl' by means of a suitable instrument, the corru tions- 382 and bead 381 swinging out su ciently for that purpose.

In Fig. 7 I have shown a cylindrical container or can body 40 which may have a suitable bottom and has the flaring portion 41 at its mouth. A continuous flange 42 extends around the upper edge of the flar; ing portion 41, as is shown in dotted lines.

The flange 42 may be corrugated and bent in beneath the flaring portion 41 which forms a shoulder or bead at the end of the can beneath which the edge of the cover part 43 may be corrugated and bent.

The cover part may be a flat blank, with or without extensions or a grooved blank wit-h or without extensions, such as shown in Fig. 5.

In the arrangement indicated in dotted lines in vFig. 7, the edges of the flange 42 and cover 43 coincide and any suitable sealing means or composition, as heretofore described, may be disposed between the two. A plurality of cover locking and detaching extensions or tabs 44 are arranged about the edge of the cover and when the cover and flange are corrugated and bent down,

[the tabs extend'a short distance inside the they may be readily engaged with a suitable instrument and removed from their locking relation with the flange 42. The tabs may be entirely dispensed with if desired, as

metal member 46, one part 47 of which en-' circles the end of the can body and has the sharp projections 48 which may be forced through the body to the opposite side and clenched to secure the member 46 to the body 45. A suitablesealing or cementing composition may be introduced between the part 47 and the can body so that there will be no possibility of leakage'through the holes made by the points 48. The member 46' has an outwardly projecting portion 50, which is disposed at right angles to the can body at its upper edge. The portion 50 constitutes an attached metal flange for the paper can, receptacle, or tube and is provided so that a metal cover may be detachably connected thereto by corrugations. It is'to be understood that the cover 51 may be metal or non-metal and the body part may likewise be of a metallic or non-metallic material. The lid 51' may have a groove 52. to center the same in the mouth of the can and to also provide a wall 53 of a sur. face comprising a centering and sealing means coiiperating with the inner wall of the container 45. The center of the cover may be depressed and a suitable gasket or sealing composition or both may be located between the adjacent faces of the flange 50 and cover 51.

For the purpose of detachably uniting the coverto the body, 'corrugating or crimping means may be applied to form a seam between the two parts comprising longi- In Fig. 9 I have shown a completed tu-' bular metal can, the body 55 of which is formed at its ends with inwardly extending depressions 56 and 57 and outstanding

continuous flanges

58 and 59 located at the ends of the depressions. The bottom 60, provided with a centering depression or groove 61 may be detachably applied to one end of the body 55 by longitudinal corrugations, a gasket and sealing composition '.located between the bottom and flange, if desired. Locking tabs formed integral with the edges of thebottom will serve to lock the parts together when the flange and edge of the bottom have been bent into the depression and alongside of the body, the depressions being provided so as to fit the seam within .the borders of the body in order that the can will be substantially the same diameter throughout its length. In attaching the bottom, the locking tabs or ex-v tensions need not be bent on themselves to form detaching tabs, as it is not customary to remove the bottom; however, the locking tabs are short enough sothat they may readily be bent down by a suitable instrument to unlock the parts and permit the removal of the bottom by bending out the corrugations thereof. g

The cover 62 has a centrally depressed portion or a groove to center the same in the mouth of the can and to form a wall 63 extending into the .mouth of the can against which a suitable plunger may rest while the flange 59 and overlapping edge of the cover are being corrugated and bent alongside the can into the depression 57. A suitable gasket, a coating of sealing-substance or'both may be applied between the flange and cover. The cover may be provided with integral locking, or locking and detaching tabs or extensions 64 which extend beneath the edge of the flange to detachably lock the parts together. The detaching tabs being doubled I under the edge of the flange assist in locking the parts together. The ends of the apertured tabs project a short distance from beneath the edge of the seam, and being flexi ble they may be engagedb a suitable instrument and drawn out. his unlocks the parts and a continued pulling on the tab increases the diameter of the cover flange due to the tendency to straighten out the corrugations therein at several points, as indicated in Figs. 1 and 3, so that the cover may be raised off the body. A bead 65 extending around the body of the can serves to reinforce the body and may provide a fulcrum for an instrument used in prying 'out the corrugated seam.

In Fig. 10 I have illustrated a common form of sheet metal can body 66 which has the integral outstanding

continuous flanges

67 and 68 at its opposite ends forming a can stead of three locking .ta

- ing composition or a gasket 671 or both may be inserted between the flange and bottom part. A plunger may be inserted into the interior of the body when the parts are corrugated together to prevent the collapse of the body. v

- The cover part 70 may be similar in construction to' the bottom art except that inb's 1 preferably provide one locking projection 701 and two apertured flexible locking and detaching.

tabs 702 all integral with the cover at its edge. In Fig. 10 an edge view of the cover blank is shown which isin most respects similar to the blank shown in Fig. 5.- In Fig. 11 one of the locking. and detaching tabs 702 is shown in sectlon, a part 71 being bent to lie directly beneath the flange 68 and extending inwardly to the can body, the part 72 of the tab being bent at right angles to the part 71and lying alongthe can body.

In Fig. 12 an elevation of a portion of a partly finished corrugated seam is shown and also a sectional view of the same, While Fig. 13 shows a view in section of the com pleted seam which detachably secures th head or cover tothe body.

It will appear from the scription that I have shown a construction in which a metallic or non-metallic cover part is secured to a metallic or non-metallic tubular part by means of corrugations and suitable locking devices, thereby providing a can with a hermetic closure which may readily be removed from the body without cutting or otherwise mutilating the parts.

The edge of the cover and a flange on the foregoingdetubular part are turned over by a concurrent corrugating and bending operation,

and there is, consequently, no drawing or.

stretching of the metal in either part. ,The locking tabs or tongues may be comparatively short, approximately five times as long as the thickness of the metal of the can body. The corrugated down-turned edges may be pulled out to release the locking tongues or the latter may be of suflicient length to be accessible to a suitable instrument from the exterior.

In all of the devices shown the corrugations are radial or disposed in planes radial to the axis of the top and body, and form a solderless seam, i. e., atwo-wall seam free from solder.

The invention may be applied to sheet metal cans, containers of paper and'the like, to vitreous containers or non-vitreous containers of flexible material. I

As fully set forth, a satisfactory joint or seam may be formed by the cooperating beveled surfaces of the corrugated flange, cover and body, the latterbeing slightly indented when the corrugation is done on the' exterior. The corrugations reduce the outer diameter of the cover part and flange part so t-hatbending the same alongside the body will not require any change in the metal as bulging or stretching.

In case the joint formed is not sufliciently tight, suitable sealing means may be inserted between the cover and the flange or; body of the can;

The cover parts having grooves or depressions therein automatically center themselves in the mouth of the can body and seat on the edge rim or on the ledge formed by the flaring part ofthe body. Locking tabs or tongues may be provided for the cover parts or the tongue may be dispensed with. Each of the tabs is flexible so that it may readily be bent without breaking. Certain of the tabs may be bent on themselves intermediate their ends so that the free ends thereof may interlock with the corrugated seam and project from beneath the seam so as to be accessible for the purpose of pulling out the corrugations of the cover part. The corrugations take up the excem peripheral length of the edges of the flange and cover, decreasing in depth from the edge inwardly. The longitudinal corrugations, folds or creases form interlocking means between said flange and cover to prevent the movement of the latter around the flange' The corrugation of the tab and tubular part together keeps the tab tight. According to the foregoing description, it will be apparent that numerous modifications are possible without departing from the spirit of the invention, and, therefore, I do not wish to be limited to the exact details as shown and described.

Having thus fully described my invention, what I claim is 1.
