ALL METAL SEALING CAP FOR PAINT CONTAINERS Filed April 21, 1930 Invent OI:
Patented Dec. 22, 1931 UNITED .STATES.
PATENT OFFICE ANDREW WYZENBEEK, on CHICAGO, rumors, Assreivon. ro BINKS MANUFACTURING 00., or CHICAGO, ILLINoIs, A CORPORATION or DELAWARE ALL METAL SEALING-CAI FOR PAINT CONTAINERS Application filed April 21,
My invention relates to caps for liquid containers, and in some of its general objects aims to provide a metal cap which will effectively seal the container even when the pressure in the container is many times greater than the external pressure, without requiring the use of non-metallic sealing portions such as are likely to be affected by the liquid with.- in the container.
Moreover, my invention aims to provide an entirely metallic container cap which can speedily and easily be attached to, and detached from, the receptacle portion of the container without the use of tools; which can easily be cleaned, and which will, automatically adjust itself to considerable variations in the shape and size of interfitting parts of'the cap and the container.
In its further objects, my invention aims to provide an easily manufactured and easily assembled container in which both the receptacle and the cap may be constructed entirely ofmetal, and in which the mouth portion of the receptacle (if'made of light material) is effectively reinforced to withstand theexpanding pressure exerted when the cap is attached to this month for sealing the container.
Still further and also more detailed objects will appear from the following specification and from the accompanying drawings, in which drawings Fig. 1 is a fragmentary view of a liquid spraying appliance embodying my invention, including a receptacle portion, a cap member, and a part of a spray-gun; the lower portion of the spray-gun and the portion of the receptacle being shown in a section taken centrally and vertically of the receptacle, and the remaining portions: of the spray-gun part being shown in side elevation.
Fig. 2 is a front elevation of the same portions.

taken along the line 5-5 of Fig. 2 and look ing upward.
Fig. 6 is a plan view of the spray appliance portions shown in Fig. 1, drawn on a reduced scale and with portions of the cap of the container broken away.
In using socalled paint-cup spray appliances, such as the one here illustrated, the liquid when thehigh specific gravity must be forced out of the receptacle by air pressure; and with many of the now employed coating materials a considerable pressure is required for this purpose; Consequently, the cap of the container must be sealed to the receptacle with such effectiveness as to Withstand this pressure, for which purpose it has heretofore been customary to interpose compressible seals between the cap and the mouth of the receptacle and the cap.
Inpractice, the materials commonly employ'ed for these seals-such as leather or rubberare gradually affected by many of the liquids used as coating materials, so that they occasionally need to be replaced. With some of the coating liquids now in use,this deterioration of the non-metallicseals by the liquid (and even by the fumes of the liquid) is so rapid that no material has been found sufliciently durable to withstand the action of the liquid for any considerable time, while also retaining the elasticity and compressibility needed for the effective sealing. Besides, such seals usually interfere with an expeditious cleaning of the container. Moreover, when such a seal crumbles or distintegrates as the result of the action of the liquid on the seal, portions of the seal may be forced up into the spray appliance along with the liquid, thereby clogging the appliance and'interfering with its op eration.
' My present invention overcomes these difting portions formed so that the needed compensation for any variations in their manufacture 1s afforded by a taperlng of these metal portions, thereby obviating the need of any compressible seal. Furthermore, my invention provides novel structural details both for the mouth end of the receptacle and for the cap, whereby the needed sealing effect and compensation for variations in thecoinmercialmanufacture of the parts can readily be secured, and whereby the pressure within the container may be utilized'for insuring a large contact area between the receptacle and the sealing portion of the cap.
Illustrative of my invention, Fig. 1 shows the upper part of a metallicreceptacle 1, which has its upwardly flaring mouth por tion tightly gripped by correspondingly formed stiffening ring 2, the extreme upper end portion 1 A of the container being spun outwardly over the upper edge of this stilfenin'gring; This stiffening ring is increased 7 in rigidityby an integral horizontal flange 3 projecting outwardly from the lower end of the ring, and a plurality of uniformly spaced lin 'ers 4: project radially of the ring from this "flange, each of the fingers being slightly twisted out of the general plane of theflange in the same direction as shown in Fig. 2. To prevent the stiffening ring 2 from slipping downwardly the receptacle desirably is bulged outwardly to present an amin lar shoulder 1 B underhanging the stifiening ring, which shoulder cooperates with the out wardly spun portion 1 A and thein'tervening mouth portion 1 C to form a groove in which the stiffening ring is seated.
Socketed in the upwardly flaring bore of the said container mouth portion 1 C is a correspondingly downwardly tapering seal ing flange?) which depends from and is integral with a cover lining 6. This cover lining has its central and major portion flat and in upward engagement with the flat and horizontal lower face of the central top portion 7 of'a container top which extends radially beyond the mouth of the receptacle, and which container top has a flange 8 depending from its periphery. This flange 8 is desirably of somewhat larger bore than'the outside diameters of the container mouth flange 1 A and the ring flange 3, and the top portion of the cover desirably includes an annular portion 9 disposed between the control top portion 7 and the depending flange 8, this annular top portion 9 being at'a higher elevation than the said central top portion 7.
The coverlining desirably comprises a cen-' tral portion 6 corresponding in diameter to the central'cover top portion 7 and connected to the'upper edge of the tubular sealing flange 5 by an annular portion 6 A which is raised above the top of the said lining portion 6, thereby aflording acurved connection between the said lining and the sealing flange, as shown in Figs. 1 and 3. The central or main portion 6 of the cover lining is underhung by a flat stiffening disk 10 which desirably is of somewhat larger diameter than the said portion 6, and which insures a rigid clamping of the cover lining to the central top portion 7 of the cover.
In the illustrated spray appliance, the cover top supports the body 11 of a spray gun, the interior of this body being connected to the interior of the receptacle by a liquid supply pipe 12 which is threaded into the said body and extends downwardly through t-he'central cover top portion 7, the central lining portion 6 and the stiffening disk 10. Threaded on the liquid pipe 12 is nut 17 which is run up against the stiffening disk to draw the gun body 11 tightly downward against the top of the cover.
The gun-body is further fastened totln cover by a hollow screw'13 which isthreaded upward into an air supply passage 1% in the said body, and which screw has its head underhanging the stiflening disk 10, so that the lining and the stiffening disk are clamped to the cover by the same means which taste the cover to the gun body 11.
lVith the top of the lining or sealing member thus rigidly clampedto the top of the cover by a stiffening dish, this entire lining or sealing member may be made ofsuch' thin metal (such as brass or bronze) that the pressure -within the container will ex and it against the mouth of the receptacle to insure a large contact area between the sealing flange 5 and the tapering mouth portion 1 C.
The depending flange 8 on the cover has suitably located portions thereof formed for interlocking with the fingers a, which fingers are here shown as three in number. For this purpose, I am showing the said cover flange as provided with three counterpart slots 15 extending circumferentially of the flange, each such slot bein considerably taller than the thickness of the fingers land sloping upward in the same direction circumferentially of the cover. Adjacent to the lower end of each slot, thecover flange has a por tion below the slot arched radially outward of the cover to afford an arched portion 16 of greater interior length than the width of one of the fingers a and to space the inner face of this arched portion farther from the axis of he cover. than the outer end of such a finger, thereby permitting the arched portion to be slipped downward over the tip of the finger when-the cover is rotatedto aline these parts.
lVhen the cover is rotated (in a direction which would be counter-clockwise in Fig. l or Fig. 6) after the, fingers have thus entered the lower ends of the respective slots, the lower edge of each slot is forced downward by engagement with the correspondingly inclined lower'face of the linger which projects through that slot, thereby pressing the cover downwardly. Consequently, the downwardly tapering tubular sealing portion of the cover is advanced spirally downward within the similarly tapering mouth portion 1 A of the container to afford a seal or" large area.
By using relatively soft metalsuch as aluminumfor the mouth of the container, and reinforcing this with a stifltening ring as above described, 1 permit the soft metal to yield sufliciently to insure an effective seal (even with air at high pressure within the container), even when the bore of the container mouth does not correspond accurately in taper to that of the sealing flange on the cover lining. To enhance this adjusting oi? the interlitting parts to each other, I desirably make the cover lining of a thin resilient metal (such as brass or bronze) which not only will afford the needed rigidity because of its resiliency and its tubular formation, but also will be sufliciently flexible to afford the needed adjusting of the interfitting conical face portions to each other.
@wing to these provisions and also to the considerable width of the interengaging por- (or height in Figs. 1 and 3),
an readily secure the desired efl'ective sealing without employing any rubber, cork, felt or tee like which would be affected by liquid or vapor within the container. In practice,
the bbdy of the attached spray gun aflords.
convenient handle for rotating the cover in either direction, and the spiral movement of the cover not only permits both a tight sealing, but facilitates the detaching of the cover in spite of such stickiness as may be due to liquid or vapors within the receptacle.
also, my use of a tapering annular seal engaging a tapering mouth portion enables me to secure a much larger contact area than can be obtained with the now common use of a ct engaging the upper end of the mouth of the receptacle, so that a relatively light clamping oi the top member on the receptacle will suflice for securing an adequate sealing.
e to the above described expanding of the sealing flange 5 by the internal pressure, and also to the flexible connection of this flange to the cover, I do not require any high accuracy in the forming of this flange and in the forming of the tapering month end bore of the container, so that I avoid expensive machining. Indeed, I have found small differences in the tapers of the two parts, or in their circular section to be immaterial, particularly if the taper of the sealing flange is not less than that of the said mouth bore.
llloreover, the cover lining can easily be de tached by merely loosening the nut 17 and the hollow screw 13, so that this lining can be replaced quickly and at low expense if necessary. So also, the space between the annular flange 5 and the depending flange 8 of the cover permits the entire interior of the cover to be cleaned easily by dipping the cover into a suitable solvent, which can be done without detaching either the spray gun or the liquid tube from the cover.
However, while I have here illustrated and described my invention in an embodiment including a desirable arrangement of the means for latching the cover to the receptacle of the container, 1 do not wish to be limited to these or other details of the construction and ar rangement thus disclosed, since changes might obviously. be made without departing ither from the spirit of my invention or from the appended claims.
Nor do I wish to be limited to the use of my invention'in connection with a container adapted to be held in the hand of the user, since its novel features will obviously be equally applicable to larger containers and containers designed for other purposesthan their use in association with spray guns mounted thereon. .I
