Abstract

A dispenser for tablets is disclosed which protects against inadvertent dispensing, e.g., by children. The dispenser includes a housing forming a tablet storage compartment, a movable slide and an operating key for the slide mounted adjacent a wall of the housing. A detent blocks movement of the slide toward a discharge position. The detent is mounted on the housing remote from the operating key. The slide is moved by simultaneous movement of the detent and operating key.

Claims

1. A dispenser for dispensing tablets, said dispenser comprising:

a housing defining a tablet storage compartment and having an outer wall;

a slide movably mounted within said housing;

an operating key disposed adjacent to said housing outer wall, said operating key being movable;

spring means resisting movement of said operating key in one direction;

said slide having a tablet dispensing portion;

said housing having a tablet discharge opening;

said operating key being effective when forced in said one direction to shift said slide to position said tablet dispensing portion in registry with said tablet discharge opening;

means for selectively blocking movement of said slide, said means for blocking comprising a detent mounted upon said housing and spaced from said operating key;

said detent being shiftable from a first position in which it engages and blocks said slide to a second position in which it is disengaged from said slide and permits movement thereof; and

spring means resisting movement of said detent to said second position.

2. The dispenser of claim 1 in which said housing comprises a top, the operating key being disposed at said top and said detent is shiftable in a plane transverse to the plane of slide movement.

3. The dispenser of claim 2 in which said detent comprises a rocker member having a first rocker arm forming an operating face;

a spring section carried by said first rocker arm;

a second rocker arm;

said slide further including a shoulder;

a blocking finger carried by said second rocker arm, said blocking finger being disposed beneath said shoulder when the detent is in said first position.

4. The dispenser of claim 3 in which said housing wall includes a vertical slot and said slide includes a lug extending through said slot, said shoulder being formed on said lug.

5. The dispenser of claim 3 in which said slide includes a lug extending through said tablet discharge opening, said shoulder being formed on said lug, said blocking finger being shiftable away from said tablet discharge opening a distance greater than the diameter of a tablet.

6. The dispenser of claim 3 in which said housing comprises a wall, a sunken recess formed therein, one of said rocker arms being mounted within said recess.

7. The dispenser of claim 3 further comprising a pin mounted on said housing, said rocker member being snap-mounted upon said pin.

8. The dispenser of claim 3 in which the first and second rocker arms are of unequal length with the second rocker arm being longer than the first rocker arm.

9. The dispenser of claim 1 in which said slide carries a depending lug;

and said detent comprises a latch member shiftable transversely of the path of movement of said slide;

said latch member having a recess adapted to receive said lug when said detent is in said second position.

10. The dispenser of claim 1 in which said detent includes a rocker member, said slide includes a lug and said detent comprises a pair of latch members shiftable transversely to the plane of movement of said slide, said latch members being configurated to form a recess for receiving said lug when said dtent is in said second position.

11. The dispenser of claim 10 further comprising a foil hinge interconnected to each of said latch members and to said rocker member.

12. The dispenser of claim 1 in which said detent includes a rocker member, a guide tab carried by said slide, a wall of said housing having a niche therein, said rocker member being disposed to engage said guide tab when said detent is in said first position, said rocker member having two arms disposed at right angles, one of said arms being disposed in said niche when said detent is in said second position.

13. The dispenser of claim 1 in which said detent is slidable, said detent comprising a dividing finger, said dividing finger extending in a direction opposite to the direction of movement of the slide and when said detent is in said first position being disposed for locking engagement with the end wall of said slide, said slide having an opening in its end wall, said finger being in registry with said opening when said detent is in said second position to permit movement of said slide and to separate a tablet positioned for dispensation from the remaining supply of tablets.

14. The dispenser of claim 1 in which said slide comprises a projection disposed within said housing, said detent including a rocker arm, said rocker arm having a first arm and a second arm, when said detent is in said first position said first rocker arm being disposed for engagement with said slide projection.

15. The dispenser of claim 1 in which said detent comprises a rocker member having a first rocker arm and a second rocker arm, said arms extending at an angle relative to one another;

said first arm extending in a direction opposite to the direction of movement of said slide;

means pivotally mounting said rocker member;

said first arm, when said detent is in said first position, having its free end disposed for engagement with said slide;

said detent, when in said second position, being disposed so that said slide can enter the angular space between said first and second arms.

16. The dispenser of claim 1 in which said detent comprises a rocker member having a second arm, said second arm being disposed in the plane of a wall of said housing opposite from said operating key when said detent is in said first position.

17. The dispenser of claim 16 in which said rocker member support pin includes bevelled sections on the end thereof and said rocker member is axially snapped onto said pin.
