v PILL DISPENSER 2 Sheets-Sheet 2 Filed April 21. 1951 INVENTOR. aza/saxc/wmlwzmr Patented July 13, 1954 UNITED rEN-T o rri c s 5 Claims.

This invention relates to dispensing devices and' more particularly to dispensing parts of bottlesand similarcontainers for dispensing pills, tablets and similar compressed or substantially solidproducts.

It is one of the objects of the present invention to provide means affording successive discharge of pills and like products from acontainer or the like.

It is another object of the present invention toprovide means permitting, selectively, the discharge from a container of a predetermined dose or closes, quantity, number of pills and like articles and in predetermined sequence (one or more at a time) It is still another object of the present invention to provide means ensuring the function of the dispensing means only when the container is placed in a predetermined position other than its normal, upright position.

Yet a further object of the present invention is the provision of means causing discharge of a pill, tablet and like article from withina container by manipulation of a simple push button, lever or slide so that the remainder of the'con'tents oi the container will not be brought into contact with a persons hand which is usually the case with conventional containers if one or more pills or'the like are to be removed from withinthe container.

Still another object of the present invention is to provide means rendering'the possibility of sell ing the container togetherwith the "dispensing means therefor in sealed condition in order to prevent tampering with the contents thereof.

Yet another object of the present invention-is to provide means conducive to a simplifiedoperation of the dispensing meanswhich will cause discharge of the contents of the container only if dispensing means made inaccordance with the present invention.

With the above and other objects in view, the invention will be hereinafter more fullydescribed and the combination-and arrangement of parts Willbeshown in the accompanying drawingiand' pointed out in the claims which'form part'of the specifica'tion.-

desire-a pill In the body l'l there-is provided a transversely extending slot 22 in which a trans verse operating slide 23 is worked to receive the pill 29 'from the pening-Zl and to intercept the column flow" of the pills while dropping-- the I pill r -=received by the slide to discharge or outlet end "to the position showndn Fig.2. simultaneousla as the slide 23 is moved inwardly to dispense the pill, a top finger or stop portion 26 is moved under the pill column to separate the pill to be dispensed from the other pills in the upper part of the opening 2!. A spring 21 is compressed at this time against an abutment 28 which projects downwardly into the slide opening 22. The opposite end of the spring 2'! lies in a recess 29 of the slide.

In order to adapt this slide for the dispensing of more than one pill, say, two pills, a stop memher or abutment 3| is pivoted to be swung from a position shown in Fig. 3 to a position shown in Fig. 5. A pivot projection 32 depends from the body, and the stop member 3| is pivoted thereupon. When operating stop member 3| by means of handle 32', the stop portion of member 3! may be projected into a recess 33 in the side of the slide opening 22 as indicated in the adjusted position shown in Fig. 5. The pivoted member 3| may be provided with a detent 34 which can cooperate with either of two depressions 35, 35' in the body I1. Accordingly, two pills will roll off the inclined surface 25 of the bottom stop portion 25, as the slide is moved inwardly to the position shown in Fig. 5.

In order that the slide 23 be not operated while thebottle is in upright position, a gravity latch 36 is pivoted out of a recess 31 provided in the body (Fig. 4) and into a slot 38 extending in the portion 25. Automatically, as the bottle with the dispenser is inverted, the latch 36 will drop down to the position shown in Fig. 4 and out of the way to permit the easy sliding of the operating member 23. The operating member 23 can be depressed with the thumb engaging the extended outer end 39 thereof. A portion 45 will come to rest against the abutment 28 to properly register hole 42 in the slide with the outlet end 24 of the opening 2|.

It will thus be apparent from this form of the invention that either one or two pills can be discharged from this dispenser by a mere setting of the stop member 3| to either one position or the other.

Referring now particularly to Figs. 7 to 11, there is shown a modified form of the invention which differs from the other form in that the pills are carried by the slide to the dispensing opening. This dispenser comprises a body 45 which is threaded upon neck 45 of the bottle 41 with a gasket 48 therebetween. Body 45 has a funnel portion 49 for receiving pills 50. This portion 49 projects into the neck 46 of the bottle.

The body 45 has a transverse opening in which is operated a slide 52. This slide 52 has a central opening 53 adapted to receive a pill 50 and to carry the same laterally to the right of the opening 51, as seen in Fig. 7, and further to discharge the pill through a hole 54. A projection 55 extends from the body 45 downwardly into a slot 55' and supports the end 56 of a spring 56 that serves to return the slide 52 to a position away from the opening 54 and where opening 53 is blocked off by the body 55. This spring 55 will return the slide 52 after it has been pressed to discharge the pill 50 through the opening 54. The latch 5'! falls down by gravity about pivot 51' to the position shown in Fig. to release the slide 52 when the bottle and the dispenser are inverted.

When the bottle is in an upright position, the latch 5'! will automatically fall to the position shown in Fig. 11 to retain the slide against lateral displacement and in order to prevent the bottle from being refilled with pills or with other contents. A stop plug 58 extends upwardly from the slide 52 and travels in a guide slot 59 provided in the body 45 as indicated in Fig. 10. Upon the return movement of this slide 52, the pill 50 will be automatically received therein. The top face 52 of the slide 52 will, as the slide is moved to discharge the pill through the opening 54, prevent the downward movement of the pill column.

It is to be mentioned that the dispenser body IT or 45 may be sealingly engaged with the neck of the bottle in any known and appropriate manner, so that the dispenser body cannot be detached from the bottle without breaking the latter. The invention further contemplates to produce dispenser body and bottle from one and the same material and to thus form a single unitary structure.

It is further contemplated in accordance with the invention to employ any tamper-proof seals to avoid detachment of the dispenser body from the bottle, if desired, so that the bottle equipped with the dispenser body will become substantially non-refillable in view of the latch mechanism 36 or 51 hereinabove referred, which in upright position of the container or bottle enters under gravity in a suitable recess of the operating slide 23 or 52, as the case may be.

It is obvious that means may be proposed which are equivalent to the aforesaid latch or look mechanism, such as a ball or rectangular element freely movable in a groove extending respective predetermined distances into the slide and body of the cap, whereby the slide will be impaired in its operation in predetermined position of said element within said groove.

While various changes may be made in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claims.
