Description
inclined to' provide cam surfaces 33.with
secured to said tank.
adapted to bejwelded or otherwise suitably At its upper end, said neck body portion is provided with an inwardly extending transverse wall 30' whichterminates in a 7 depending flange 31. At two diametrically f' opposite points, parts of thewall 30and the flangeBl are cutaway to providetwo pas sageways 325thr0ugh which are adapted to ing member, as will later appear. "The cutting away of parts of said wall 30 and flange 31 provides two depending flange portions 31 of si'ibstantially semi-circular form and thelbottom edges of. these flange portions are which cooperate the closures locking fingers 6 in effecting detachableconnection of the closureto the neck. In order to liinit rotary movement of the closure locking fingers up along the cam surfaces 8,}each flange portion is provided at'th'e rearof its cam surface with a depending stop projection 34 .andfjust. in' advance of these projections,
eachcamsurface'is providediwith a recessed 7 portion or dwell 35, inwhi'ch'dwells'the closure locking fingers seatswhen .the -.closure isin fully locked position {on the neck.
The closure is appliedtQ the: neck in the usual manne'r'fo'f bayonet-joint connections, the i closure locking fingers I 6 being a ssed down through 'the pass'ageways' 32''}oftlie neck: "The closure is then turned ina iclo.ck-; w se directionwh'ich causes the closure fin- -gers to'ridef up the jcain surfaces33'until I reach the dwells 35 thereim'furjtheri'rog tary movement ofsaid fingers in this ,dire'c 'tionbeingprevented by the; stop projections 34; said fingers ride" up the' camsurfaces 33, they move downwardly in openings 7 of" the, fclosure inner" wall, v such" downward In YQ 'e b in p rm tte yfih 'r i' y of the arms ".8 of the closure locking member,

to turn it in the reverse direction, whereupon the closure locking, fingers leave the dwells 35and ride do'wnthecam surfaces 33 to the passageways 32, after which the closure can be readily lifted from the neck.
Preferably, the closure is provided with a yieldinggasket 38 which is adapted to snug- 1y surround the cup-shaped portion of the closure inner wall and to engage the lower surface ofthe horizontal flange portion-1 thereof; While engagement of the gasket '38 with thecup-shaped portion of the closure inner wall is usually snug enough to maintain the gasket in position, said gasket can not escapefrom the' closure due to the outwardly extending locking fingers 6..of the "closure locking member. Whenthe closure, is applied to the neck as in Fig, 1, said gasket is compressed between the flange portion'l of the closure inner wall and the top transverse wall 30 of the neck, Said gasket is of insufii cient' width tofreach' the "cylin: fdrical skirt;portion"1l of the closure outer wall sotliat theventopening or openings 22 in the margin jofvthe'horizontal flange .portion'l of thejclosure inner wall are not covered thereby.
