CAI CLOSURE.
Application'led April 17, .1922. Serial No. 553,974.
To all lwhom t may cof/wm:
Be it known that I, JAMES S. REID, a citizen of the United States,residing at Cleveland, in the countyv of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Cap Closures, of which the following is a specification.
the parts of which extend but slightly`above the top portion of the container; which closure is provided with an improved baiiied air vent; and whichv closure is simple in construction, is made of a minimum number of parts, and which can be manufactured and sold at low cost.
Further objects of the invention are in art obvious and in part will appear more 1n detail hereinafter.
The invention comprises the construction and varrangement of parts hereinafter described and claimed.
In the drawings, which represent one suitable embodiment of the invention, Fig. 1 is a piani view of the capmember; Fig. 2 is a vertical sectional view of the closure applied to a container; Fig. 3 is an inside plan View of the cap member; Fig. 4 is a plan view of a portion of the container with the cap member removed; and Fig. 5 is a vertical sectioal view of the container on the line-5 5, Fig. 4.
Referring to the drawings, 1 represents a portion of a fuel tank in which is an opening, such as a filling opening, 2. :At diametrically opposite points at the/ edge of said opening, radially extending recesses 3 are provided, and the metal of thev container around said opening and between said the container around the opening 2. The
lower or inner edges of said flanges are inclined, as shown in Fig. 5, so as to form cam faces 5 for engagement by the locking spring fingers of the cap member, as will later appear. Each of said cam faces is provided with a dwell portion 6 and a lug or projection 7, the latter limiting the rotary movement of the cap member.
The cap member comprises a substantially circular top portion 8 having a central dome 9 and a plurality, four being sho-wn, of radially extending projections or finger portions 10, the latter facilitating the turning ofthe cap member. The upper edge portion of a cylindrical or cap-shaped member which comprises a cylindrical wall portion 11 and a bottom portion 12, is secured to the to-p portion 8 around the central dome 9 by crimping, as indicated at 13, Fig. 2.
At the Ybase of said cap-shaped member and at diametrically opposite points, portions of the metal of the bottom portion 12 and the cylindrical wall portion 1l are sheared and bent upwardly, so as to form ,two spring fingers 14 which are adapted for engagement with the cam faces 5, as before referred to. Said fingers extend upwardly and outwardly, as viewed in Fig. 2, the outer Y ends of said lingers extending beyond the cylindrical wall portion 11 of the cap shaped member.
The openings 15, formed by the upwardly extending sheared fingers 14, provide air passages between the fuel tank or other container and the'chamber 16 in the cap-shaped member and the central dome 9, the latter being provided with an aperture 17 leading to the atmosphere. While the openings 15 are suiiiciently large for the passage of air therethrough, the sheared ngers 14 serve as a baie to largely prevent the splashing of gasolene or other contents of the container into the chamber 16.
The cap member is applied by inserting the depending cap-shaped portion thereof through the opening 2 ofthe container, the` spring lingers 14 passing through the radially extending recesses 3. The cap memb'er may then be turned, the spring fingers 14 riding up the cam faces 5 with gradually increasing binding action. The cap member' may be turned until said ngers strike the projections 7 at which point the outer ends of said fingers will lie in the dwell portions 6 in the cam faces, so that the cap member will be securely locked in closed position.
An annular gasket 18, of cork or the like,
is preferably provided, being suitably secured to the inner face of the top portion 8 of the` cap member and snugly surrounds the upper portion of the depending capshaped member. When the cap member is p in closed position, the gasket 18 lies between ythetop portion 8 of the cap member and that portion of the lcontainer surrounding the opening 2, so that said opening is effectively sealed. Due to the great resiliency of the spring lingers 14, the gasket is relieved of undue pressure and grinding action, so that its life is materially lengthened. The ,gasket is also protected from the contents of the container.
To remove the cap member, it is only nec-,
essary to turn, it in the reverse direction, whereupon the spring fingers 14 will ride down the cam faces and the cap member may7 ilbe lifted bodily from the container.
of said sheared lingers providing an air' vent which affords communication between the inside of the container and the air chamber within said cup-shaped portion.
2. `A closure device for containers having spaced recesses and cam portions, comprising a cap member having a top Aportion land a hollow cup-shaped locking portion providing an air chamber within said cupshaped portion, said top portion being provided with a vent affording communication.
between the outsideatmosphere and said air chamber, and said cup-shaped portion beimY provided with outwardly extending sheared ngers adapted to enter the recesses of said container and engage the cam portions thereof upon relative'4 rotation of said cap member and said container, the formation of said sheared ngers providing a balled air vent whichv affords communication between the inside of said container and the air chamber within said cup-shaped portion.
3. A closure device for containers having `spaced recesses and cam portions, comprising a cap member having a top portion provided with a centrally disposed dome and a hollow cup-shaped locking portion having its upper edge secured to said top portion around the dome thereof by a crimping operation, said top portion being provided in the dome thereof with a vent affording communication between the outside atmosphere and the air chamber within` said cup-shaped locking portion, said locking portion being provided with outwardly extendingsheared fingers adapted to enter the recesses of the container and engage the cam portions thereof upon relative rotation of said cap member and said container, the formation of said sheared fingersproviding a vent which affords communication between said air chamber and the inside of said container.
4. A closure device for containers having spaced recesses in` cam portions, comprising a cap member having a top portion and a cup-shaped locln'ng portion secured thereto, opposed corner portions of said locking portion being sheared to provide locking fingers, thevfree outer end portions of said sheared lingers being adapted to enter the recesses of the container and engage the cam portions thereof upon relative rotation ofsaid cap member and said container, said sheared fingers extending upwardly and outwardly from the bottom of said cup-shaped locking portion.
In testimony whereof I hereby alix my signature. t
