Abstract

A tablet or pill ejector is disclosed consisting of at least three detachably secured sections in the general shape of a pen. The front end of the device is provided with a hole communicating with axially aligned bores formed longitudinally in the sections and through which a pill may be ejected quickly. An ejector rod is provided in the bores adapted to move from a cocked position to a released position wherein it passes instantly through a pill retaining member located in the front section of the device. Cocking and trigger mechanisms are provided. In an alternate embodiment the front section is provided with a revolvable barrel adapted to contain a plurality of pills for ejection. The rear end of the device may be provided with a storage compartment and cap.

Claims

1. A tablet ejector generally in the shape of a pen and comprising at least three sections:

a front section, a middle section and a rear section;

said front section having a first central and longitudinal bore and at least one pill retaining means at the rear end thereof;

said middle section having a front portion provided with a second longitudinal bore in axial alignment with said first bore;

a cavity located rearwardly of said second bore, said rear section having a longitudinal third bore axially aligned with said first and second bores;

said third bore is of slightly larger cross-sectional area than said first and second bores;

an ejector rod slidable longitudinally in said first, second and third bores between a first rearward cocked position and a second released front position wherein the front end of said ejector rod has passed through said pill retaining means;

a circular plate rigidly secured to said ejector rod and extending within said cavity, a coil spring having one end abutting the rear wall of said third bore and the other end abutting said circular plate;

said coil spring surrounding said ejector rod, a foot carried by said rod and located immediately forwardly of said circular plate in said cavity and radially outwardly biased therein by a second coil spring;

a protuberance formed in the inner surface of said cavity and adapted to retain said foot in said cocked position;

a small slit made in the wall of said middle section immediately rearwardly of said protuberance;

a pocket clip rigidly secured to the exterior wall of the device and having a forward end overlying said slit and being slightly flexible, whereby said forward end can be pressed into said slit to release said foot and said ejector rod.

2. A tablet ejector as defined in claim 1, wherein said front section is provided with a revolvable barrel having a longitudinal axis;

said barrel being provided in turn with a plurality of radially spaced-apart holes, each constituting a pill retaining means;

lock means to prevent further movement of one of said holes when it comes into registry with said first bore; and

means to remove said barrel for reloading wherein the reloading means consists of a straight and rigid member having a rear portion serving as an axle for said revolvable barrel;

the forward portion of said member being of smaller diameter and adapted to slide in a frontward channel formed in said front section;

said member further having a forward end which can be grasped by the fingers of a user and pulled forwardly to free said barrel for removal.

3. A tablet ejector as defined in claim 1 wherein the rear portion of said rear section is formed with a compartment and a detachable cap is provided to close the latter, whereby a supply of pills can be conveniently stored in the device.
