This invention relates to a portable container which upon closure cannot be opened until the lapse of a predetermined interval.

Cbjects ci my invention include providing such a container, the predetermined locked interval of which may be set when open and cannot be changed when closed. Another object is to provide such a container which will automatically rewind itself and reset the interval duringv the opening and closing of the container. A :further object is to provide a light weight portable automatic time-lool ed container simple in design and` practicable for mass production.

in this speciiication when l refer to cigarettes, such reference is only as an example to clarify this presentation, and it should be understood that my invention applies and refers equally to, any drug, food or other matter, the consumption ci which a person may desire to control or limit in some respect.

Other objects and novel features within the scope of my invention will be apparent from the following specification especially when considered in conjunction with the drawings in which:

-igure i3 a fragmentary View of the interior Figure le is a fragmentary side view of Figure 13.

' is a sectional fragmentary View taken i ntialy along line i5l5 of Fig. 9.

es i .o 3 show a cigarette case including three parts preferably made of transparent plastic, a 'nach section lil, a cigarette chamber lid iii hinged 'thereto by a piano type hinge i6 and a .ha-lrn cover i' for a timer mechanism i3. A plurality of projections lA extend into a rectangular shaped cigarette Vholding chamber I9 from 2 the inner Walls of back section lll and lid l5 (Fig. 9)

Lid l5 is called a lid purely for convenience of explanation. Because it also contains cigarettes, it could also be said that I5 is the oontainer and the back section le is the lid. This .should be lrept in mind in interpreting the specification and claims hereafter set forth since any differentiation between the lid and the rest of the container may be purely artiical.

in alternate form oi' projection E3B is shown Figures 13 and lll. These are formed by the fight angle intersection of a plurality of grooves Projections AEA and B are arranged to position standard length cigarettes horizontally and the longer or king size vertically in an orderly and parallel manner. The cigarettes are further maintained in this position, each in its own location, whether the case be full or not, by two separators 2l and 22 which are hinged together as a part of piano hinge l@ as shown in Fig. ll. Each of the two ends of each separator are formed around respective torsional springs 23 in which is inserted hinge pin Ed. Springs 23 are effective to normally separate the separators 2l and 22, pressing each against the cigarettes in the respective halves of the case which in turn causes lid l5 normally to spring open. The separators are designed in a U shape without crossing each other, to be adjacent to at least three Walls of chamber i9 to position the cigarettes therein whether they be standard or king size.

Figures 5 and 5 show a winding `and setting shaft 2? to which are fixed a winding gear 26, an arm 2i?, and a knurled knob 29. Bearinged on shaft 27 is a great gear 3 l, a clock spring barrel from which an ear 35 is bent to turn a notched disk Si also journaled on shaft 2l. A clock spring 35 interconnects shaft l with great gear 3l or barrel 32, the two latter parts being intern connected.

The knob end or shaft il? is bearinged in timer cover l i and the other end is bearinged in a back plate 3l.

Slidably mounted in an elongated hole 38 in back plate 3l is a stud 3Q on which is journaled a ratcheting idler gear el. A groove in a dist; d2 which is iixed to stud Se positions ratchet spring t3 which also bears on two of four spacers 6.

These four spacers il@ position a top plate ill relative to bottom plate 3l. Between these plates and bearinged therein are various conventional and standard timing gears anddevices such' as gear 48. Idler gear 4! normally meshes with great gear 3l and gear 48, but ratchets when the great gear turns clockwise as viewed in Figures l, 5, 10, 11 and 12.

A balance wheel i9 is also shown. Gear i8 and balance wheel 49 and the gearing, etc., between them may be considered conventional and are not shown in detail. Any suitable escapernent or other timing device may be substituted for them within the scope of my invention.

Back plate 3? is bent forwards 90 to form the bottom face of the timer I3. portion of plate 3l there is mounted an L-shaped rack bar 52 which meshes at certain times with winding gear 26. Back section lll is shouldered to furnish a sliding bearing for rack 52 and to retain it in a position adjacent to back plate 3l. rlhis shoulder is not shown. A link 53 interconnects lid I5 with rack 52 by means of studs 55 and 55. The movement of lid l5 is not limited to 90, but is thus shown for purposes of explanation only.

One end of a shaft 5I is bearinged in back plate 3? and the other end in timer cover Il. Loosely fitted on shaft 6I is a channel shaped stamping 62 and a linger lever 53 positioned between the legs of stamping 62 and notched to nest therewith for mutual actuation. One leg of stamping 52 is extended to form tooth Ell Which is positioned to move into notch 55 of notched disk 3ft when the latter is positioned as shown in Figures 5 and 12. Tooth 55 also blocks the movement of stamping 52 by nger lever 53 when notch 55 is out ci alignment.

-Latch pin or bolt il extends through suitable openings in stamping 52 and the bent edge of back plate 31 and also through a notched out portion of rack 52. Latch pin 1i is circumferentially grooved to ensure its retention within a loop of a spring i2. Both ends of spring i2 make substantially a right angle bend about shaft 5i and press against cover ii or back sections It at 113 in such a manner as to resiliently press either stamping 62 or latch pin i! or both downward to engage a latch hole i5 of an ear 'i5 in lid l5. One side of ear l5 is cammed to press latch pin Vil independently of stamping 52 out of the way to allow a latch pin i! to enter hole 'i5 when the lid l5 is closed at a time when notch 65 is out of alignment with tooth 55.

One end or leg of spring i2 terminates at i3, but the other is looped in a manner to engage ear 33 to form a ratchet stop i5 and continues to engage an elongated hole in finger lever 53. Ratchet stop 75 allows ear 33 to pass under it when turned clockwise, but acts to stop the mechanism when notch disk 3i is turned counterclockwise to a position Where notch 55 is receptive to tooth 55.

The timer cover l? is clamped to back section It by Vtwo screws passing through holes 8l in the back or front plates 3'! or 13'! and threaded in cover Operation The timer is designed (1) to prevent the manual withdrawal of latch pin 'ii for a preset interval after lid i 5 has been closed; (2) to rewind and start upon the closing of lid i5; (3) to reset automatically for repetitive intervals; and (4) to allow gradual change of the interval period through a plurality of small subdivisions of the range from substantially zero time to maximum time by the user only when the lid is open.

With the case open, as shown in Figures 8 and 9, rack 52 is disengaged from winding gear 25 Along the turned A and in this position the main spring assembly including parts 25 to 34 may be turned clockwise by turning knob 29, since in this direction gear 5i ratchets rather freely. Suppose we set the assembly and more particularly notch f5 of disk 5e in the position shown in Fig. 10 at 150 degrees or a little less than 40 minutes from the ultimate stopping position of disk Sli shown in Fig. 12. The numerals shown in Fig. 1 are on the transparent timer cover I'! through which notch 55 of disk 34 is clearly visible. The numerals are positioned to indicate the length of time which must elapse Vor the length of the interval before the case can be opened, on the assumption that the timer mechanism will provide for the great wheel 3| to make one complete turn in minutes. Any other timing of the great wheel is within the scope of my invention. Ear 33 is accordingly now positioned degrees of travel from ratchet stop 76.

Now if lid l5 is slowly closed, then during its initial movement rack 52 does not engage winding gear 25, but when it does contact gear 25 it turns the winding shaft 2'! together with arm 2S counterclockwise almost one complete turn to the position shown in Fig. 1l. Note that ratchet gear il has prevented the great gear 3! from turning with shaft 2'! and accordingly energy equivalent to practically one turn of the clock or main spring 35 has been stored therein. Also ear 53 and notched disk 35 have remained stationary but the tip of arm 28 has shifted contact from one side oi ear 55 to its other side.

However great gear 3|, spring barrel 32, ear 33 and notched disk 55, all turn slowly counterclockwise as the timing mechanism functions until the parts are stopped in the positions shown in Fig. 12 by ratchet stop '15. Latch pin li can now be disengaged by manual pressure on iingei' lever 55 at the will of the operator. Note that arm 25 has not moved and cannot, because rack 52 is locked and in engagement with winding gear 25. Neither can the interval setting be altered while lid i5 is closed.

rl'he main spring as indicated by the travel of arm 2t from the position shown in Fig. i() to that of Fig. ll was originally wound very close to 350 to 36D degrees, but as shown in Fig. 12 it has unwound only 150 degrees and the timing mechanism has stopped at this point. When the latch pin 'El is withdrawn by manual pressure on finger lever 53, the 200 to 216 degrees of uneXpended energy within the main spring 35 react on the rack bar 52 to aid in opening the lid i5. This force is in addition to the force in torsion springs 23. The unexpended force of the main spring is completely expended when the mainspring assembly, parts 25 to 34 assume the positions shown in Fig. 5.

However, since in going from the position shown in Fig. 10 to that of Fig. 1l, arm 25 made practically full turn and in moving from the position shown in Fig. 12 to that shown in Fig. 5, the winding gear 26 and the winding shaft 21 have turned only 200 to 210 degrees, they still have 150 degrees yet to go before rack 52 disengages from gear 25, accordingly, it is clear that the complete opening of the lid will turn notched disk 3G and all the parts 25 to 35 clockwise to the starting positions shown in Fig. 10. If now the case lid i5 is reclosed the timer will be started, rewound and reset to repeat for an identical subsequent interval.

Rack 52 and link 53 would be in the position shown in Fig. 5 when parts 25 to 35 are in the position shown only at the end of a 90 minute or 350 to 360 degree interval. I H

With the case open if it is desired to lengthen the interval then knob 29 can be turned slightly clockwise. It is desired to decrease the interval, then knob 29 must be revolved clockwise at least until ear 33 has passed ratchet stop 1S, since ratchet gear il will not allow assembly 26 to 3,4 to be turned counterclockwise.

Although exemplary forms of the invention been described in detail hereinabove and illustrated in the accompanying drawings, it should be understood that the invention is capable of embodying a wide variety of modications without departing from the spirit of the invention or the scope of the appended claims.
