Abstract
A child resistant tablet dispenser is disclosed wherein the dispenser is comprised of a body portion and a release mechanism. The body portion may be hollow and cylindrical and contain therein a plurality of tablets in a tablet magazine. The tablets may be individually dispensed through the release mechanism which has a child resistant dispenser requiring multiple actions before an individual tablet may be dispensed. The multiple actions required on the release mechanism may be in two different planes thereby requiring movement in a horizontal plane and movement in a vertical plane in order to release a slide actuator and then depress a release button for opening of the release mechanism lid. Upon opening of the lid, an individual tablet is forced outward from the cylinder of the body portion and dispensed.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention elates to a child resistant tablet dispenser wherein tablets may be individually dispensed after activation of a slide actuator and press button whereby the activation requires a two-step child resistant process thereby resisting child tampering and opening of the package.




2. Discussion of the Prior Art




Prior art child resistant tablet dispensers typically are comprised of flat horizontal based dispensers wherein childproof packaging or other material is required to be removed from the outer packaging prior to dispensing of the tablets or pills. Such container packaging is shown in U.S. Pat. No. 5,575,399 wherein a flat packaging container is shown which requires compression of child resistant tabs in order to separate the upper and lower horizontal package members.




Other tamper proof pill dispensing apparatus are known such as disclosed in U.S. Pat. No. 4,485,938 wherein individual pills are dispensed through a discharge outlet. Safety latches are also provided in diametrically opposite positions in order to prevent activation by children.




Other tablet dispensing receptacles are known such as that disclosed in U.S. Pat. No. 3,942,683 wherein a cylindrical housing is capped with a spring biased cover which is simply rotatable about a pivot point thereby providing access to the contents of the package.




However, none of the prior art package dispensers provide a child resistant tablet dispenser wherein the tablets are retained within a cylindrical body in magazine type formation and wherein the dispenser has a child resistant release mechanism for gaining access to the contents of the package.




SUMMARY OF THE INVENTION




The object of the present invention is therefore to provide a child resistant tablet dispenser wherein the dispenser has a release mechanism which may not be activated by a child or which is at least child resistant.




A further object of the present invention is to provide a tablet dispenser having a release mechanism wherein the release mechanism is child resistant and which contains a cylindrical body wherein a plurality of tablets may be contained.




An additional object of the present invention is to provide a child resistant tablet dispenser wherein the release mechanism is readily activatable preferably by an adult and wherein the release mechanism releases a hinged lid while also individually dispensing the tablets contained within a tablet magazine.




An additional object of the present invention is to provide a child resistant tablet dispenser wherein a tablet magazine is spring biased so that, after individual depletion of the tablets from the top end, each of the tablets may be singularly indexed for release upon the next activation of the release mechanism.




It is an additional object of the present invention to provide a child resistant tablet dispenser wherein the release mechanism, which preferably prevents a child from activating the mechanism, incorporates use of a slide actuator which must be used in conjunction with a release button, both actions requiring movement and perpendicular planes.




A further object of the present invention is to provide a tablet dispenser wherein the release mechanism is child resistant and wherein a hinged lid is biased such that upon activation and opening of the lid, individual tablets are dispensed from a cylindrical dispenser body.




The above and other objects are accomplished in accordance with the present invention by providing a child resistant tablet dispenser having a release button and slide actuator as a release mechanism, the release button requiring movement in the vertical plane and the slide actuator requiring movement in the horizontal plane in order for the hinged lid to be opened for releasing individual tablets contained within the package body.











All of the above outlined objectives are to be understood as exemplary only and many more objectives of the invention may be gleaned from the disclosure herein. Therefore, no limiting interpretation of the objectives noted are to be understood without further reading of the entire specification and drawings included herewith.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




The child resistant tablet dispenser


10


of the present invention is depicted in

FIG. 1

with a partial cutaway view shown therein. The dispenser


10


is comprised of a body portion


20


and a release and dispensing mechanism


40


which is attached to the top open end of the body portion. The body portion


20


is constructed of plastic or other similar material and may be cylindrical in design in order to retain therein a plurality of tablets to be dispensed. At the top open end of the body portion


20


is the release mechanism


40


which provides a child resistant dispensing mechanism wherein action is required along both the horizontal plane and the vertical plane. This action is required in the present embodiment by movement of slide actuator


35


in the left or right direction as well as depression of the release button


34


in order for the lid


30


to rotate about hinge


31


thereby releasing a tablet from the open end of the release mechanism


40


. Once dispensed, the lid is re-closed thereby locking the release and dispensing mechanism


40


and requiring re-actuation of the child resistant feature.




The body portion


20


, as indicated above, may be constructed of plastic or other similar materials such as aluminum, tin, metal alloy or other similar component. The body portion


20


may be designed as a hollow cylinder or ovoid


25


which retains therein a tablet magazine


21


for individual dispensing of the top most tablet


27


, as is shown in FIG.


2


and FIG.


3


. The tablet magazine


21


rest upon a platform


22


in the interior of the body portion


20


and within the cylinder


25


, the cylinder


25


matching the size and geometry of the tablet magazine


21


. The platform


22


on which the tablet magazine


21


rests is spring biased by spring


23


which is attached to the base


24


of the cylinder. The spring forces the tablet magazine in the upward direction thereby allowing the individual dispensing of tablets within the tablet magazine


21


. As each individual tablet


27


is dispensed from the top most end of the tablet magazine


21


, the spring


23


forces platform


22


upward thereby maintaining upward pressure on the tablet magazine and maintaining direct contact of the top most tablet


27


with release mechanism


40


.




The cylinder


25


of the body portion


20


may also have on the interior portion thereof a plurality of channels or ridges for the platform


22


to ride vertically thereon in order that the platform


22


may move in the vertical direction in either the upward or downward direction in ready fashion. Further, multiple springs may be provided to maintain the efficacy of the bias against platform


22


when the tablet magazine is in the near empty condition.




As is depicted in the figures, the child resistant tablet dispenser


10


of the present invention additionally has a release mechanism


40


mounted on the top most end of the body portion


20


. The release mechanism


40


is designed to provide a child resistant dispensing feature wherein multiple actions are required in order to prevent dispensing of the tablet from the tablet magazine by a child. The release mechanism


40


of the present invention as depicted in the figures maybe comprised of a release button


34


which requires depression thereof and which must be completed after movement along a horizontal plane of the slide actuator


35


. Slide actuator


35


therefore prevents downward movement of the release button


34


unless the slide actuator


35


is placed in the release open or unlocked position, as is depicted in FIG.


2


and FIG.


3


. When the slide actuator is in the closed or locked position as shown in

FIG. 1

, the release button may not be depressed or the lid


30


may not be raised.




As shown in FIG.


2


and in

FIG. 3

, the slide actuator has been rotated in a counter-clockwise fashion in order to allow the button


34


to be depressed with a downward force. Once the button


34


is depressed, the lid


30


opens and rotates about hinge


31


allowing the top most tablet


27


to be dispensed through opening


32


of the release mechanism. Continued downward force on the release button


34


causes the top tablet


27


to be slide forward and out of opening


32


thereby allowing a user to pull the tablet


27


from release mechanism


40


. Thus, as can be seen, the child resistant tablet dispenser


10


of the present invention requires that a multiple number of actions are required in order to dispense the tablet from the tablet magazine


21


and through the release mechanism


40


.




The present invention is utilized to dispense individual tablets from tablet magazine


21


. These individual tablets may be comprised of pharmaceutical material, ver the counter medications, tobacco products or other material in which restrictions must be placed upon child access. Thus, it is desirable to prevent easy access to the contents of the dispenser


10


of the present invention and a child resistant dispenser is therefore desired. The overall size of the dispenser


10


of the present invention may be such that is readily hand held and actuated by multiple movement of the users thumb.




Returning to the figures, as shown in

FIG. 4

, the release mechanism


40


is depicted therein. The release mechanism


40


is comprised of the release button


34


and the button support bar


33


which extends downward therefrom. The button support bar


33


contacts the upper surface of the slide actuator


35


when the slide actuator is in the closed or locked position as depicted in FIG.


4


. Upward pressure is maintained against the release button


34


by spring


36


which resists downward pressure movement of the release button


34


and which therefore will require, depending upon the strength of spring


36


, significant agility and downward force in order to open the release mechanism


40


.




The release mechanism


40


further is comprised of lid


30


which rotates about hinge member


31


once the release button


34


is depressed downward after slide actuator is opened. Lid


30


is hingedly connected to lid mount


39


which, in this embodiment, is fixed between the lid and the release button


34


. As shown in the figures, the inner portion of the lid


30


has welded or integrally formed therein a retaining arm


42


which is a rigid structure allowing translation of the downward force placed upon the release button


34


into upward rotational force placed upon the interior upper surface of the lid


30


. Thus, downward force of release button


34


will cause the lid


30


to rotate about hinge


31


. The retaining arm


42


is also sufficiently rigid enough such that when the release button


34


is in the locked position as is depicted in

FIG. 4

, upward force on the lid


30


will not cause the lid to open and the retaining arm


42


will maintain the lid


30


in the closed and locked position. However, once the slide actuator


35


is in the open unlock position, the release button


34


may be depressed and retaining arm


42


causes lid


30


to rotate about hinge


31


and lid mount


39


.




Also shown in FIG.


4


and

FIG. 5

is the slide arm


41


which is an additional semi-rigid or rigid structure which allows upward movement of the lid


30


to be translated to sliding movement in the horizontal plane by the slide hook


44


such that a right to left motion is completed and the top most tablet


27


is dispensed from the release mechanism


40


. Thus, as is shown in

FIG. 5

, the release button


34


has been depressed, retaining arm


42


has forced lid


30


to rotate about hinge


31


, and the slide arm


41


, working in conjunction with the upward movement of lid


30


, forces tablet


27


to be dispensed from the tablet magazine by the slide hook


44


.




As is shown in FIG.


5


and

FIG. 4

, beveled surface


43


works to allow the top tablet


27


to be removed readily by slide hook


44


by providing a curved or smooth surface for dispensing thereof. Once the top most tablet


27


has been released from the tablet magazine


21


, the lid


30


may be closed thereby forcing the slide arm


41


and slide hook


44


in the closed position as depicted in FIG.


4


. Further, the slide actuator


35


may be biased by another spring in the horizontal plane thereby forcing the slide actuator


35


in the closed and locked position once lid


30


is reclosed after dispensing of a tablet. Thus slide actuator


35


may have formed thereon a retaining notch for maintaining the slide actuator in the open position until the button


34


is depressed thereby causing the slide actuator


35


to work in conjunction with a biasing spring forcing the actuator back in the closed and locked position once the release button


34


returns to its upmost position as caused by the spring


36


.




As an alternative to the release button and slide actuator depicted in

FIGS. 1-5

,

FIG. 6

depicts an another embodiment


100


of the release mechanism wherein instead of a release button, upward force is required along thumbpad


133


in order to open lid


130


. Initially however, in order to force the lid


130


in the upward and open position, the slide actuator


35


must again be activated in order to allow the support bar


138


to bypass slide actuator


35


. Thus, in operation, the slide actuator


35


is placed in the open unlocked position as depicted in

FIG. 5

, and upward force along thumbpad


133


allows the lid


130


to rotate about hinge


131


thereby opening the dispenser. As is shown, the hinge point


131


may be constructed of a hinge bracket


132


which straddles the lid


130


and which allows rotational movement of the lid


130


thereon. A biasing spring


136


may be provided such that the lid


130


is biased to the closed position and therefore, once opened, the lid


130


will attempt to reclose and lock. The hinge bracket


132


may straddle the lid


130


on the exterior surface thereof. However, alternative hinge points may be constructed thereby allowing rotational movement of the lid


130


about any axis defined by hinge


131


.




In conjunction with the lid


130


is a similar slide arm


41


which allows the dispensing of individual tablets from the tablet magazine


21


upon upward movement of the lid


130


. Thus, thumbpad


133


provides a frictional contact for the user to rotate the lid


130


about hinge


131


thereby releasing the top tablet from the tablet magazine


21


through the use of slide arm


41


and slide hook


44


. Such a design may be desirable when downward force is not necessarily desired and instead an upward force or sliding action would be preferred while still maintaining the multiple action requirement of a child resistant dispenser.




One skilled in the art will appreciate that the present invention can be practiced by other than the described embodiments which are presented for purposes of illustration only and not by limitation.
