May 5, 1959 H. R. TREGILGAS POCKET TABLET DISPENSER AND UNIT TABLET CONTAINER THEREFOR Filed Dec. 17, 1955 INVENTOR HAROLD R. TREGILGAS W8 l l l .mmmmwmmmmmmmmmw llllll i mi Mal).
POCKET TABLET DISPENSER AND UNIT TABLET CONTAINER THEREFOR My invention relates to a pocket tablet dispenser and unit tablet container for the dispenser wherein a series of tablets may be contained to be kept in a convenient manner within ones pocket and having a similar appearance to an ordinary pen or pencil with a pocket clip for holding the same.
A feature resides in providing a tablet dispenser wherein the tablets are held concealed within the dispenser ready for immediate use and without contaminating or exposing the tablets, remaining in the dispenser, to the air.
It is a feature to provide a unit tablet container which may be in the form of a plastic tube containing about 20 tablets, more or less, with both ends of the container hermetically sealed and each tablet being separated from another by a gelatin disk which acts to seal the individual tablets within the unit container so that when the unit container with a series of tablets is placed within the dispenser, one tablet at a time may be dispensed from the lower end of the dispenser.
It is a feature to provide a dispenser and a holder for a series of tablets wherein the user of the dispenser may quickly dispense a tablet when needed without being evident to other people or to cause any embarrassment to the user of the dispenser. My dispenser is particularly adapted for use for nitro-glycerin tablets, and my unit container provides a means of sealing the tablets individually from moisture; consequently, the tablets retain their strength much longer than where they are dispensed or taken from a bottle such as the old method which is now employed for dispensing such tablets. It is extremely difcult for an older person in pain with heart trouble to get a smallbottle from the pocket and then extract a small pill from the bottle.
My dispenser can be designed to carry any size tab-let to provide a convenient and quick means for the user to carry various tablets such as saccharin tablets for diabetic cases. I have found that the quick convenience provided by my ydispenser to the user is of primary importance, particularly in heart cases where it is important that the patient be able to use the nitro-glycerin tablets as prescribed by his doctor. Thus, a life may be saved in the convenience provided by my dispenser to the user.
A compart nature and the convenient manner in which it may be carried in ones pocket provides the user with a dispenser which is ready at hand. If the user desires, the tablet may be dropped directly on ones tongue or into the mouth. Furthermore, the inconspicuous nature of my dispenser having a character similar to an ordinary fountain pen or pencil provides the user with a more desirable means of dispensing tablets than where the` same were ordinarily carried as heretofore in vials or pill boxes.
It is a feature to provide a dispenser wherein a half turn twist of` the button at the top ofthe dispenser, in. one direction will lock the same against the dispensing States Patent of tablets therefrom, while a half turn twist in the other direction -will release the dispensing mechanism of the dispenser so that a tablet may be readily ejected therefrom when the operating button is pushed downward. Spring means hold the operating button normally out ot operation.
It is a further feature to provide a dispenser wherein the unit tablet container is supported in the lower end of the dispenser while the upper end thereof is provided with a push rod operated by a ratchet rod and spring means to move the push rod a step at a time in the operation of ejecting a tablet. The operating button which is depressed to eject a tablet may be marked with a red cross on the top end thereof or the top end may be formed polygonal in shape so that the dispenser may be easily distinguishable on sightor feel from. other pocket pens or pencils. This button may be of a white nature so that the red cross will show up readily. It isdesirable that either the entire dispenser be made of a transparent plastic material or at least the lower end thereof be of such a construction so that the operator may see exactly how many tablets remain in the dispenser. With the unit tablet container of a transparent nature, the operator has the convenience of being fully advised as to the number of unused tablets remaining in the container. Pills may be supplied in the unit tablet container for use in the dispenser, and when filled the ends are sealed to preserve the potency of the pills against exposure to air.
The unit tablet container which holds the individual tablets is preferably translucent and may be colored red for nitro-glycerin tablets, blue for saccharin tablets or any other identifying color may be incorporated in the body of the container.
The features of my invention will be more fully and clearly hereinafter dened.

Figure 12 is an enlarged View of a restrictingv sleeve which has been removed from the. casing. Figure 13 is an end View on the linerl313 of Figure 9 as indicated by the arrows.
Figure 14 is an end View on the line 14-14 of Figure l() as indicated by the arrows. s
, Figure 15 is anenlarged view of a spring lockingmern-` assente y i portion l1 and `a lower endportion 12. These portions 1I, ll and 12 are threadedtogether at 13 and 14W Thus, the hollow casing of the dispenser A may be taken apart for disassembling the same or putting it together to form unit dispenser for tablets,` pills" or other items which are usually adapted to be prescribed by a physician lfor a patient orwhere an individual wishes toA `take certain vitamin or tablets.` u l i i The dispenser A is preferably made of transparent plas-` ticso thattho operator or `user of the dispenser may readilyi observe the operation of dispensing tablets and to be quickly advised as to any remaining tablets in the dis penser. The upper portions `1t) and 11 may be made translucent or of colored plastic which may not be transf l parent if desired. v r
t `The operating button 15 for my dispenser A is preferably made of white plastic with a red cross 16 formed infthe upper end to distinguish my dispenser from ordinary ball point, fountain pens or pencils. This identitieation is `furthe benet of the patient or user of the to the dispenser A.
\ Thus, the reservoir tube B forms ameans of providing a supplyof tablets 17 which are adapted to be `disn pemedout of tbedispensernat the will `of the operator.
I provide a pocket clip C having a spring nature for holding the dispenser in the pocket of the user.- The pocket clip C is held between the portions 10 `and 11 as indicated in the drawings. i
The operating parts of my dispenser A are of a simple character and comprise the toothed rod 20 with anop erating end 2l. The rod 20 may be formed integrally with the operating head or button l or secured thereto in any suitable` manner. `A disk `member 22 is supported by the collar: 23 in a fxedposition on the upper end of the rod 28. M A coilspring24 extends around the upper end of the lrod 20and into the recess formed in the operatingbutton 15. This spring 24 is placed` in` poaition `before the disk 22 with the collar 23is positioned onthe upper end of therod 20.`
` Anmuasrzs isformed in the member 11 to 11min me outer movement ofthe operating button1l5, i
A hollow plunger member 26 formed with the closed operating end 27 isprovided to operate on the eiectorrod 20. l The plunger member 26 is formed with oppositely disposed spring arms 28 near the upper end thereof which are adapted to engage with the teeth 29 formed on thek ejector rod 20 when the rod 20 is turned by the button 15 to bring the teeth into engagement with thev spring arms 28 of the member 26.@ i
Whenitheeiector rod 20 is in position sosthatltbe spring arms 28 engage the teeth or are inlline with the teeth 29 `soasto engage the same, the operating rodlis in :the `proper position to push the plunger member 26 downwards degree at a time each time the operating button 15 is depressed by the operator. The ejector-rod 20is placed `in operating position by turningthe button clockwise and out of operating position with :the spring 28 lwhen the button 15 is turned counterclockwise.` When the ejector rod 20 Ais out of operating position, to operate the plunger member 26 the button l5 may be pressed inwardly without operating the mechanism of the dispenser, and thus, no tablets will be dispensed when the in thisposition. x
The upper end of the plunger member 26 is provided with a disk member 30` which is formed with an annular groove 31 in which the spring 32 is positioned. The spring 32 frictionally holds the plunger member 26 against free movement in the casing member 10 of the dispenser as illustrated in Figure3.
A guide member 33 is held in the casing member 10 by collar members 34 and 35. The bar-like portion 36 of the guide member 33 between the collars 34 and 35 is adapted to tit in the notch 37 formed in the disk end 30 of the plunger member 36 when the parts are assembled in the casing of the dispenser A. Thus, the guide member 33 holds the plunger member slideably positioned within lthe casing and against turning so that the turning of the operating N button 15 will turn the teeth 29 of the rod into or out of engagement with the springs 28 of the plunger member 26.
The unit tablet container B is adapted to be placed in the lower end y12 ofthe `dispenser" A. This is` accomplished by separating the parts 10 and 12 on the threads 14 and inserting the unit B in the dispenser ready for operation.` At the time when the unit B is placed in the dispenser A, the plunger member 26 is placed in its uppermost position so that the end 27 may be brought to bear against the end disk 19 of the unit tablet holder, and thus, force the tablets out of the front end of the unit B when pressure is exerted against the operating button l5. The tablets 17 it reasonably loose in the tubular casing 18 of the unit B while the disks` 19 are sutlciently snug to form close compartments between cach tablet 17. The disks 19 are preferably formed of a gelatin-likesubstance so that if the patient or` user of my dispenser drops a disk 19 into his mouth or is carried into the mouth of the user of my dispenser, the disk will cause no harm but will be readily dissolved in the alimentary canal of the patient or person.
The lower end of the dispenser out of which the tablets 17 are dispensed may be provided with a spring restricting sleeve 38 which is formed with inner spring ends 39 and outer spring lingers 40. This sleeve 38 is forced into the outer end of the portion 12 of the dispenser A as illustratcd in Figure 16 and is adapted to provide a spring restricting means for holding the disks 19 and the tablets 17 from falling out of the dispenser. As the end 27 of the plunger 26 is forced against the tablets, the lowcrmost tablet spreads the fingers 40 suliciently to` allow the same to be ejected therebetween whereupon the fingers 40 close and retain the following tablet until further pressure is exerted on the end 27. Thus one tablet may be dispensed at a time. This restricting spring sleeve 38 also holds the unit tube 18 of the unit B from being lforced out of the dispenser while the tablets 17 with the disks 19 are being dispensed.
The underside of the disk 22 is formed with a projecting portion 41 which is integral with the disk 22 and is adapted to rotate therewith when the operating button 15 is rotated clockwise or counterclockwise to position the toothed rod 20 in the plunger tube 26. Figure 4 shows a portion of the disk 22 broken away to expose the portion 41 to show the shoulder portion 42 thereof bearing against the guide bar 36 when the disk 22 is turned counterclockwise as indicated by the arrow.
Figure 5 illustrates the disk 22 rotated clockwise in the direction of the arrow causing the shoulder 43 to bear against the opposite side of the guide bar 36 than that shown in Figure 4.
When the operating button 15 is rotated counterclockwise to position the member 41 with its shoulder 42 against the guide bar 36, the ejector rod 20 is turned out of engagement with the spring lingers 28 of the plunger member 26.
When the button 15 is turned clockwise, thenr the shouldery43 is brought to bear against the other side of `the guide bar 36 (Figure 5), and in this position, the ejector rod 20 is set to cause the teeth 29 thereof to engage with the spring ngers 2S and by depressing the button 1S, the plunger member 26 is caused to bear against the outer disk 19 of the unit B, and continued pressure against the button will eject one of the tablets 17 out of the lower end of the dispenser A.
After a tablet has been ejected by the operator, the button 15 can be turned counterclockwise, as a safety measure, to prevent accidental dispensing of a medical tablet 17.
It will be apparent that my dispenser A provides a very desirable means for inconspicuously dispensing the medical tablets 17. Thus, any patient of a doctor who is required to take certain medical tablets periodically can carry the dispenser in his pocket and not only quickly dispenses a tablet at a time therefrom but without virtually disclosing to anyone that he is taking such a tablet. Furthermore, the convenient manner in which the tablets are supported within the unit B so that a new unit can be supplied for the dispenser A is of primary importance. I have found in critical heart cases my dispenser is invaluable to provide quick means of providing the patient with nitro-glycerin tablets when needed.
It will be apparent that while the drawings and specilication illustrate a form of my dispenser that variations may be made in the style, construction and details thereof within the scope of the following claims without departing from the purposes and intentions of my invention.
