Definitions

  • a common type of closure cap for a filler spout on automobile gasoline tanks is adapted for bayonet connection with such spout.
  • the spout comprises a top provided with a rim having diametrically opposite female notches therein through which latching lugs on the cap are insertable to provide a bayonet type connection upon turning of the cap in one direction over the top.
  • Opposite cam surfaces are provided over which the latching lugs can ride. Each of these surfaces extends from and slopes downwardly from adjacent the end of a notch and terminates adjacent a downwardly extending stop.
  • a spring pressed sealing disc structure is secured to the underside of the cap top to seal against the spout rim upon twisting or turning of the cap in said one direction, provided the latching lugs are inserted properly through the notches.
  • the arcuate or helical retaining feet form a screw threaded connection with the cam surfaces of the spout.
  • latching can be effected substantially without interruption by turning or rotating the cap in one direction.
  • lt can be unlatched by turning the cap in an opposite direction, and removed by lifting the ends of the retaining feet through the spout notches.
  • the retaining feet retain the cap loosely on the spout until the cap is manually removed.
  • the construction permits relatively wide notches compared to the width of the latching lugs.
  • the ends of the retaining feet may be provided with downwardly extending end projections insertable into the respective spout notches to locate the same when the cap is placed on the spout for latching it.
  • the invention has as its objects, among others, the provision of economical and simple means on a closure cap for an automobile tank filling spout or the like, to insure that the cap is properly seated on the spout before it is latched, in combination with such means of simple and economical means for retaining the cap on the spout while it is being unlatched while simultaneously allowing venting of gas pressure which may build up in the tank, thus preventing the gas pressure from blowing the cap away from the spout as it is being unlatched.
  • FIG. 1 is an isometric view looking at the underside of the closure cap of this invention
  • FIG. 2 is an isometric view of the filling spout hereof illustrating its relationship to the cap of FIG. 1 before they are latched;
  • FIG. 2A is a developed elevational view illustrating a filling spout with a deep cam to compare it with a shallow cam shown in FIGS. 2 and 4; the blocking prong and retaining foot hereof being illustrated;
  • FIGS. 3 through 3-D are vertical sections taken along line 3-3 in FIG. 2 which includes an intermediate arcuate section, illustrating the relationship of the safety cap hereof to the filling spout in various positions during the latching operation; in these Figs.:
  • FIG. 3 illustrates the position wherein the retaining feet are ready for positioning in the spout notches

  • FIG. 7 is a schematic elevational view illustrating an embodiment wherein a downwardly extending end projection is provided at the end of each retaining foot insertable into a spout notch to facilitate location of the notches;
  • FIG. 8 is an isometric view of the underside of a late model emission control gap, illustrating the retaining lug construction employed therein.
  • the positions of the parts are referred to considering the top of the spout and the cap as the uppermost part. It is to be understood, however, that the spout and the cap may be arranged, for example, horizontally, depending on the environment wherein the spout is employed. Although particularly adapted for the filler spout of an automobile tank, the invention hereof is applicable to any other filling spout for a tank wherein pressure can build up in the tank.
  • FIGS. 1, 2, 3 through 3D, 4 and 5 a more or less conventional filling spout 2 for an automobile gasoline tank of the shallow cam type, is illustrated in association with the closure cap construction hereof. These parts have a bayonet type connection.
  • Filling spout 2 has a top comprising rim 3, and horizontal flange 4 extending inwardly and substantially even with rim 3.
  • Diametrically opposite entry notches 5 and 6 which provide for a bayonet connection, are formed in flange 4 which has a down turned flange 7 on each side of the spout extending between entry notches 5 and 6.
  • the under edge of one of down turned flange 7 forms a cam surface 8 which extends from an edge of notch 5, slopes gradually downwardly and terminates adjacent a downwardly extending stop 9 at opposite notch 6.
  • a like cam surface 11 and stop 12 are formed on opposite flange 7 with cam surface 11 diametrically opposite cam surface 8, and stop 12 diametrically opposite stop 9.
  • the cap 13 hereof which cooperates with the described spout, comprises a flat top 16 having diametrically opposite upright lugs 17 for grasping to turn the cap on the spout, and a downwardly extending cylindrical flange 18 which fits over the spout.
  • a centering hub 19 is secured to the underside of cap top I6, and a conventional spring pressed sealing disc structure 21 is fixedly secured between the cap top and centering hub 19.
  • Centering hub 19 encloses a conventional gas vapor emission control valve 21' which is preferably employed but it is not necessary for the latching features of this invention.
  • the parts of the cap thus far described are conventional.
  • centering hub 19 has fixedly secured thereto a pair of diametrically opposite outwardly extending latching lugs 22 and 23 which are provided by the top ends of downwardly extending blocking prongs 22 and 23' respectively, insertable through the notches.
  • latching lugs 22 and 23 are integral with blocking prongs 22' and 23, respectively, they may be provided as separate elements in line with each other. Extending from the lower end of the respective blocking prongs 22' and 23 and integral therewith are arcuately shaped diametrically opposite downwardly inclined or helical retaining feet 22 and 23, respectively.
  • feet extend in the same circumferential direction about the axis of the cap, and are rigid with the centering hub 19 and the respective blocking prongs.
  • Each forms a generally L-shaped structure with the associated blocking prongs and latching lugs; and because of their arcuate shape and downward inclination they provide a screw cooperable with the cam surfaces or edges 8 and 11.
  • the ends of retaining feet 22 and 23' are insertable through the respective notches 5 and 6. It will be noted from FIGS. 1, 2, and 3 through 3D that in latching the cap the ends of retaining feet 22" and 23" are inserted through the respective notches 5 and 6, and turned or rotated until the upper latching ends 22 and 23 of blocking prongs 22' and 23', respectively are fully inserted through the respective notches 5 and 6 such upper ends 22 and 23 forming the latching lugs as was previously noted.
  • the latching lugs 22 and 23 ride over cam surfaces 8 and 11 whereupon the cap becomes fully latched when the latching lugs and associated blocking prongs engage against the respective stops 9 and 12; tight latching and sealing of the cap being maintained by the spring pressed sealing disc structure 21.
  • FIGS. 3 through 3D illustrate various positions as the cap is turned or rotated clockwise to latch the same
  • FIG. 4 schematically depicts development of the L-shaped structure 23, 23 and 23 insertable through notch 6 in the spout from adjacent which the end of sloping cam surface 11 extends.
  • the left-hand portion of FIG. 4 shows the position just after retaining foot 23 has entered notch 6, while the phantom lines indicate further positions after the cap has been rotated clockwise.
  • cam surface 11 has a slight gradual slope from edge 6' of entry notch 6. This facilitates insertion of the retaining foot and rotation of the L- shaped structure.
  • latching lug surface 23 rides against cam surface 11, being pressed against it by the spring pressed sealing disc structure 21 as it engages the rim of the spout.
  • latching lug 23 and associated blocking prong 23 engage against stop 12
  • the cap becomes tightly latched by the spring pressure exerted by spring pressed sealing structure 21.
  • the opposite L-shaped structure 22, 22' and 22" is simultaneously inserted through notch 5 (FIG. 1), and latches in the same manner.
  • blocking prongs 22' and 23' insure that the cap becomes evenly seated on the spout rim 3 before it can be rotated for latching the same, to thus prevent latching with only one lug. Unlatching is effected by rotating the cap in a counterclockwise direction until the ends of the retaining feet are removed through the respective entry notches 5 and 6.
  • retaining feet 22 and 23 are underneath latching surfaces 8 and 11, respectively, as the cap is being unlatched; and during this period pressure built up in the tank is vented through entry notches 5 and 6, and between the flange l8 and the outside surface of spout 2.
  • pressure built up in the tank is vented through entry notches 5 and 6, and between the flange l8 and the outside surface of spout 2.
  • such pressure cannot blow the cap away from the spout because the retaining feet can engage such surfaces upon axial displacement of the cap under said pressure, to thus retain the cap on the spout until the gas has been completely vented whereupon the cap can be removed manually from the spout by turning it to move the lower ends of the retaining feet through the spout entry notches 5 and 6.
  • possible injury to the person unscrewing the cap is precluded.
  • Each of the latching lugs and associated blocking prongs and retaining feet are of a width substantially less than the width of each of spout notches 5 or 6 as can be seen best from FIG. 5. Thus an initial loose fit is provided which facilitates locating the notches and entrance of the ends of the retaining feet into the notches.
  • FIG. 4 illustrates a deep cam construction wherein latching surface 11" extends from an edge 6" of flange 7" a substantial distance. Consequently, it blocks smooth entrance of retaining foot 23 underneath cam surface 11
  • the shallow cam not only has the advantage described but it is also easier to manufacture, and consequently reduces cost compared to a deep cam.
  • the precise depth of the cam surface below the rim of the spout is not particularly critical, nor is the degree of slope of the cam surface critical. All that is desirable is for the slope to be gradual, and for the end of the cam surface to lead gradually from the entry notch as shown in FlG. 4 to allow retaining foot 23" to slide into position easily.
  • a suitable cam slope is between about 4 to 6.
  • FIG. 8 depicts a present popular type of late model closure cap for a deep cam on the spout.
  • Diametrically opposite latching lugs 31 are offset or staggered relative to opposite retaining lugs 32 which are provided on downwardly extending brackets 33 also located diametrically opposite each other.
  • two distinct turning operations are required to latch the cap, after retaining lugs 32 have been inserted through the spout notches, namely, an initial turning until latching lugs 31 are opposite the notches in the spout whereupon the cap drops down vertically, and a final turning to latch the same by the latching lugs riding over the cams.
  • each end of a retaining foot for example retaining foot 22" with reference to FIG. I, may be provided with a downwardly extending end projection 22 insertable into a notch 5 to facilitate location of the respective notches when the cap is placed on the spout for latching it.
  • This feature is not necessary but may be employed if so desired.
  • the spout is about 2% inches outside diameter with horizontal flange about 54 of an inch wide, the depth of cam flanges 7 at the highest point being about 3/16 of an inch, notches 5 and 6 about it: of an inch wide, blocking prongs 22' and 23' each about 3/16 of an inch wide, and about inch long, and stops 9 and 12 each of about if: of an inch wide and if: of an inch long.
  • the arcuate length of each retaining foot is about 7a of an inch and its angle of inclination about 5".
  • each of the L-shaped structures is a rigid continuous structure rigid with centering hub 19. It may be formed as a stamping integral with the hub or as a separate rigid structure welded to the metal hub.
  • the previously described embodiment of the invention is an internal bayonet connection which is common for closure caps on automobile gasoline tanks; and the latching and L-shaped structure is on the exterior face of centering hub 19 for entry through internal bayonet notches in the spout.
  • the principle of the invention is also applicable to an external bayonet connection, which is illustrated in FIGS. 6 and 6A wherein, for example, a radiator filling spout 36 is shown.
  • Opposite exterior entry notches 37 are provided in horizontal exterior flange 38 of the spout from which extends a downwardly extending flange 39.
  • the under surface 41 of flange 39 provides the camming surfaces.
  • L-shaped structures 42 having the described retaining feet 43 with locater extensions 44 at their ends, are rigid with the interior face of centering hub 45. They are insertable through notches 37 and the upper ends 44 serve as latching lugs to engage against cam surfaces 41 when the cap is fully positioned on the spout and rotated in a clockwise direction.
