In the exemplary embodiment of the invention dis-V closed in the drawings, a dispensing closure is shown to comprise a body member 10 arranged to extend through an opening 11 provided in a container 12 adapted to hold a quantity of material to be dispensed, such as salt. 'Ihe bodymember is generally at or wafer-like and is provided with an outer end 13 which extends just slightly outwardly of the surface of that portion of the wall of container 12 deiining the periphery of opening 11. Associated with body member 10 is a lid member 14 alternatively receiveable within the body member to effect a closure thereof, and extendable outwardly of the body member to permit a dispensing operating therethrough. ln the instant invention, the lid member is arranged to be flush across the outer end l13 when it is in the closedA position and improved means are provided for hingedly connecting the lid member to the body member to permit this disposition land to maintain the lid member in an out of the way position during a dispensing operation. In the illustrated embodiment this connceting means comprises a pair of hinges 15 which additionally serve as a means for aligning the lid with the body member during a closing operation. Hinges 15 preferably extend from outer end 13 thereby allowing the outer end to have a continuous peripheral engagement with the body member around opening 11.

Coacting means are provided on the lid and body member to retain the lid removably ush across the outer end of the body member in the closed positon. A more detailed description thereof will-be made herefollowing, it being sufficient for a general understanding of the invention at this point to note that these means include rib elements 16 on the lid member and bead means 17 on the body member. The instant invention further comprehends the provision of a body member having an internal polyangular cross-section providing lan improved spout action during the dispensing of the particulate material. Further, a novel distribution of foramina 18 in a transveres inner wall 19 extending across the body member aids in this improved spout action and provides an improved action in returning any particulate material which may have remained temporarily on the body member subsequent to a dispensing operation.

A general description of the illustrated embodiment of the invention having been presented above, a more specific description of the elements thereof is made herefollowing. As best seen in Figs. 2 to 6, body member 10 conn prises a member having a laterally outwardly enlarged outer end 13 provided with a peripheral, outwardly opening groove 13a arranged to receive the inner peripheral edge 12a ofthe container wall portion deiining opening 11. To assist in the installation of the body member, the laterally outer surface 10a of the inner end of the body member may be beveled inwardly to spring the container wall slightly during insertion and allow it to snap into the groove 13a. As best seen in Fig. 2, outer end 13 eX- tends continuously to have an unbroken sealing engagement with the container wall, thereby precluding the passage lof undesirable materials, such as water vapor, into' the container, and precluding undesirable leaking of particulate material from the container outwardly.

Extending through the body member, from end to end thereof, is a stepped passage or bore 10b having an outer portion 10c, a relatively narrower inner portion 10d, and a transversely extending, peripheral shoulder 10e therebetween. It is preferred that passage outer portion 10c have a polyangular cross section, herein disclosed as tnangular. Bead means 17 extends marginally around the outer end of passage outer portion 10c, and wall 19 extends transversely across the inner end of inner passage portion 10d. Foramina 18 are generally uniformly distributed `throughout walt 19,y with ,a number thereof closely juxtaposed to the wall of the body member defining inner passage portion d. One foramen 18a, at

the'` apex; 107, ofl the body Vfmember, is arranged fto have its laterally outwardpoitiongcoineident; with; Ythe inner servesgasaY means for `controlling the` flow tofprovide 'an improyed'spoutelike. actiorr ,wherein` the dow is directed generally over the apex lof. Y Y f Lids member; 14A comprises a dat. closure elementiv havingga' peripheralgconguration; generallycomplementary tothc polyangular cornigurationgof passage outer portion 10a ofgthe body member. A depending peripheraL flange 1421i extends completely around Vthe margin of the lid member toV bereceivedfwithin passage portion 10c when thelidfis the closedposition off Fig. Y7. The longitudinal'extentofY ange 1'4armay be such that the inner tip 14b thereof will-be spaced slightly, fromshoulder 10e when the lid member is` disposed ush across the outer end of. the body member. Rib meansl, which may comprise discontinuous, separated elements as seen in Fig. 2, are spaced longitudinally inwardly from theouter surface of the lid member to be received inV outer passage portionYV 10c below the b ead 17 and toY extend transversely outwardly of the bead means into contact-with the body wall dening passage portion 10c. Thus when the lid member is disposed inthe closed position of Fig. 7, the ribelements coact with bead means 17 to lock releasably the lid in the closed position.

To limitrtheY inward movement of the lid member through passage; outer portion 10,c, flange entl 14B is disposed to abut shoulder "10e of the body'V member whenthe 1id,member is movedfjust 'slightly inwardly of Ythe flush position. Thus, rib elements 16 coacting withv bead means"17, and 'ange end 1'4b coactingwithshoulder 10e mutually coact topermit a limited movement of the lid member longitudinally within passage portion 10c. Y f Hinge means 15i extends from ,outery end' 13 lof the Vbody member todispose theV lid.` member in a position generally normal; to the transverse extent of body mem- Y ber 10 when the lid is, in the open position (as seen in Fig. 6).' Thus, duringa dispensingoperation, the lid member is automatically maintained out of' the path of ow of the material being/dispensed. l'Preferably, hinge means ,'1'5 comprises two such hinges, which hinges are spaced substantiallyv apart to provide improved alignment of' ther lid member withY the passageouter portion V10c to permita simple,gsubstantially fool-proof. closure operj ation. Y VAs best seen-in Figs. 6 and .7', hinges 15j are secured to the outer surface of the lid member, precluding any. interference with theflush positioning of the lidmember relative to outer end 13, in the .closed position thereon@ Y Y To assist in moving the lid member. from thev closed position, a tab. 14e is extended from the outer surface ofthe; lid kmember adjacent its apex to overlie` apex 10)c Y of the body member when the Vlid member is in the closed position. o As Vthe outer surface of the Vlid membery is flush-with' outer end 13, the disposition of tab 14e may Yof; the simple, integrated structure it may be formed advantageously by such mass production means as plas-V Yti: moulding. It is preferredithat the material have some resilient characteristics to provide theproper functioning ofhin'ges 15 andto allow the snappingv of the lid @einem member intothe passage VAportion 10c past thebead means lt is believed that the operation of the device is substantially self-evident from the above structural description. The closure is mounted on the container by inserting the inner end of the body` member through a suitable opening 1G provided in the container wall, until the surrounding container -wa'll portion' snapsy into place in groove 13a of the body member. AssumingA lid member i4* to beY disposed inthe open position of Fig. extending outwardly from the container'wall, to close the device, the l-id member is hingedly swung'on hinges 15 until it is received'in, passagefouter portion "10c, ribs =16 snapping past bead 17., Thelidpmembcr Yis then releasably locked between bead 17 and shoulder 10e of the body memberY and extends completely across the passage to effect a sealing closure thereof. Y

'To dispensel particulate material from the container, lid member 14 is swung tothe open` position of 'Fig'.VV 6 by manipulation of tab 14e. Container 12 is then disposed to effect the pouring of the material through foraminous wall 19, with` apex 10) of the body member disposed generally downwardly duringY the dispensing operation. Upon completionA of the dispensing operation, the container is returned to the upright position wherein the body member extends generally horizontally and any particulate material remaining,Y on the body member tends to fall backwardly into the container through the foraminouswall. This return of particulate material is aided in the disposition of foramen 18a at the apex of the body member as the material would normally tend to collect at this point subsequent to the completion of a dispensing operation and thus, substantially all ofthe material not actually dispensed will be returned to the container. 'Ifhismaintans the dispensing closure relatively Yfree of such material which would otherwise have a tendency to prevent proper closure thereof.
