DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention pertains to a dispensing apparatus designed to equip a tube or box containing pills, sweets or similar granulated products. It applies particularly, although not exclusively, to drugs containing tubes, particularly homeopathic drugs.
Traditionally, homeopathic products are generally found in the shape of spherical pills called "granules" whose diameter varies from 4 to 5 millimeters, or "globules" whose diameter is approximately 1.5 millimeters. These spherical pills are contained in a cylindrical tube. Upon each use, the operator opens the tube and takes a given number of pills therefrom. Thsi operation is particularly delicate in the case of homeopathic drugs since the unused pills must remain in the tube without coming into contact with the hands of the operator to avoid contamination.
Experience shows that by tilting the tube, the operator drops an excessive number of pills which must be put back in the tube, thus, contaminating them.
The present invention is designed to eliminate these disadvantages by offering a simple and economical device, capable of precisely delivering the desired number of pills, granules or globules. It also pertains to the method of utilization of this dispenser.
SUMMARY OF THE INVENTION
A dispenser, such as the one described in the invention, is designed to be recessed in the mouth of a tubular container for containing pills or similar products that are approximately spherical, and is characterized by the fact that it includes a fixed rear opening in front of which an axial tubular chimney moves laterally with reference to a fixed lateral stop which is used to retain the pills that are gravity fed into the chimney when the latter is aligned with the opening. The stop then clears the chimney when the latter is laterally reset in position and is no longer in alignment with the opening.
According to another feature of the invention, a number of means are provided inside the lid of the tube to make the chimney travel laterally, away from its reset position.
According to yet another feature of the invention, such actuation means include a roughly tapered boss extending inwardly at the center of the bottom of the lid, while the rear opening is centered on the geometrical axis of the tube and while in reset position, the chimney is laterally offcentered in the tube, its internal channel pointing to the tip of the lid tapered boss.
According to a still further feature of the invention, the internal diameter of the chimney is approximately equal to the diameter of the pills to be dispensed, while the distance between the rear of the chimney and the fixed stop is equal to a multiple of that diameter.
According to yet another feature of the invention, a number of means are provided to axially set the position of the lateral stop, which allows for the selection of the number of pills to be dispensed.
According to another feature of the invention, a number of return means including an elastic soft blade equip the chimney to bring it back to its reset position when it is no longer activated from the boss of the lid.
