No. 403,491 Claims. (Cl. 221-186) 'I'fhis invention rela-tes -to an article dispensing device and more particularly concerns -a slim, compact form of article dispenser which is adapted to carry a .stack of small articles such as pills, etc. for selective dispensation as required.
This invention is an improvement on the device set forth in applicants copending application Ser; No. 280,210, filed May 14, 1963, now Patent No. 3,159,308.
An object of this invention is to provide in an article dispenser ofthe slim, compact pencil type, improved means -for supporting the stack of articles immediately above the bottommost article as the same is being dispensed.
Another object of this invention is to provide in a device of the character desoibed, improved supporting means which is in a normally at, planar condition but is responsive to operation of the device to dispense a single article, to positively deflect a portion of the supporting means from its planar condition so as to curve the same and bring it into an operative position; the supporting means being restored to its normal planar condition when the article has been dispensed.
Other objects of this invention will in part be obvious and in 'part be hereinafter pointed out.

The device of the instant invention comprisesessentially a pair of telescopically related tubular members in slidable relation Ato-each other with spring means for maintaining the members in a normally longitudinally displaced relation, the members having dispensing openings normally in offset relation bu-t registrable upon #depressing the inner member within/the .outer member against the action-of -the spring to allow the bottommost article of a stack of articles within the inner member to be dispensed through the registering openings.
The device further includes simple support means for the stack of articles While the bottommost article is being dispensed, such means comprising a thin flat, flexible 'but stiff strip in normally planar form and which is disposed -within the device to become operative only oni depressing th-e inner member within the outer member, in which case the free end of the strip is curved and positively deflected toward the Ilongitudinal axis of thel inner member so as to bring the end edge of the strip into supporting engagement with the bottom of the stack of articles; the strip reassuming its normal planar condition 3,269,597 Patented August 30, 1966 when the inner member moves back toits normal, nondispensing position.
l"Thus, as shown4 in FIGS. 1-4, '10 designates an article dispensing device embodying the invention and adapted to carry a stack of karticles suclras pills vor the like.' The same comprises a pair of coaxially and reciprocably related elongated tubular members 111, 112, which are shown, for the purpose of illustration as being of rectangular cross-section. 'Members 11, 12 are formed of die cast metal but, also may be made of molded plastic or the like.
The outer member comprises a channel shaped element 13 having a front Wall 14 and sidewalls 15, 16. The side walls 15, 1.6 are formed along Ytheir outer longitudinal edges with outturned, slight flange portion-s 17. A back wall member 18 is arranged for slidably closing the open side of sidewalls 15, 1|6;member 18, having inturned flange portions'19 along the opposite edge portion thereof, for engaging'fl'ange portions 17 .on side Walls 15, 16. The member 11 is closed at itslower vend by la bottom Wall 20 formed with a centrally disposed socket 21 on its inner surface, vfor-the purpose hereinafter appearing.
The front wall 14-of member 11 is formed with a dispensing opening 22 adjacent the lower end thereof.
The innerrnember 12l in the form of an elongated bar, is formed with an article carrying recess 23 dened by a single side wall 24, a front'wall 25 and a rea-r wall 26. The recess 23 terminates at its upperend in spaced lrelation to the outer end of bar 12 to provide a depressivble head portion 27 which projects outwardly of the upper open end 28 of outer member 11. The inner member 12 is maintained in a longitudinally displaced relation to outer member 11 by a coil spring 29 which is seated at its lower end in -socket 21 of outer member 11 and at its upper end in a socket portion 30 formed on the underside of a solid abutment portion 31 which deiines the lower end of recess'23.
Abutment portionV 31 includes a transversely and downwardly inclined surface portion 32 which extends at its lower end to the lower end of a dispensing opening 33 formed in the -front wall 25 of inner member 12. The
' 29, by Way of head portion 27,` the opening 33 will be brought into registry with opening 22, to allow thebottommost article. Ato pass outwardly through said openings, aided bythe inclined surface 32, asshown in FIG. 2.
When head portion 27 of inner member 12 is released, the same is restored to its normal elevated position by the action vof spring 29; ythus leaving the openings 22, 33 in'oset, nondispensing'relation to each other, as shown in FIG. l.
Means is provided for supportingthe stack of articles in recess 23 while the bottommost yarticle A is being dispensed. To this end, there is provided a thin,flatstrip 35 which is formed of stiff but exible material such as metal or plastic; such strip being a normally planar condition but'being adapted to be exed into curvedV form and for thereafter reassuming its'planar. condition when left unrestrained.
Strip 35 is anchored at `its lower end 36 to a shouldered portion 37 of bottom wall 20 Vof the outer member 11, 'by adhesive or'the'like, as at 38. The strip 35 extends vertically upward and is adapted to project into a narrow guide slot'39 formed in abutment portion 31; said slot allel to back wall 26. Slot 39 opens at its upper end 3 into recess 23 at the upper end of inclined abutment surface 32.
The rectilinear guide slot 39 has an extended arcuate slot portion 40 extending from the upper end thereof; said slot portion 40 being formed in side wall 24 and projecting at its outer end toward the longitiudinal axis of member 12. The stri-p 35 has one lateral edge portion 35A adapted to be received in slot portion 40 as inner member 12 is depressed `toward its dispensing position, thereby curving the Ifree end portion 41 of strip 35 and bringing the end edge 41A thereof into supporting engagement with article A of the stack of articles as article A is being dispensed.
It will be apparent that normally planar strip 35 is positively flexed to curve the free end portion 41 into its article supporting position in timed relation to the outward movement of the dispensed article A so as to support the stack of articles as article A passes outwardly of the dispensing openings 22, 33. Furthermore, as inner member 12 is retracted to its normal position, the free end portion 41 of strip 35 is no longer constrained to its curved condition, and reassumes its normal planary condition in rectilinear slot 39.
The supporting strip 35 has a width somewhat less than the depth of recess 23, particularly when the articles of the stack are relatively small, particularly as to their dimension between Walls 25, 26. In this case, support strip 35 is guided by a single curved slot portion 40. However, when the articles to be dispensed are somewhat larger and with extended dimensions between walls 25, 26; then inner member 12 is provided with opposed side walls 24, 24A. In this case, wall 24A is also formed with a curved slot portion 40 aligned with slot portion 40 on wall 24 to receive therein the other lateral edge of support strip 35; thereby providing full support on both sides of said strip in its curved, stack supporting condition. Of course the support strip Will now have a full width between side walls 24, 24A.
Alternatively, in lieu of a through slot -to form guide portions 40, side wall 24 may be formed on its inner sur- -face with -a guide groove 42 of curved form which extends from slot 39, see FIG. 8. Such groove may also occur on the inner surfaces of opposed walls 24, 24A, to guide the support strip 35 as the same .is curved at its free end in the manner previously described.
To limit the reciprocal movement of inner member 12 relative to outer member 11, detent means is provided in the form of a shallow, longitudinally extending recess 43 formed in the outer surface of -front Wall 25 of inner member 12 with a shoulder detent 44 projecting from the inner surface of front wall 14 of outer member 11 into said recess 43 and to form stop means for limiting the travel of inner member 12 relative to outer member 11.
While device is shown as having a rectangular cross section, it is understood that the same have cross sections of other geometrical configurations to suit the articles of the stack carried therein.
As various changes might be made in the embodiments of the herein disclosed invention Without departing from the spirit thereof, it is understood that Iall matter herein shown or described shall be deemed illustrative and not by way of limitation except as set forth in the appended claims.
