DESCRIPTION:
BRIEF SUMMARY
The invention concerns a measuring/dispensing device for granular or powder products.
A number of measuring/dispensing devices for powder or granular substances find an increasingly wider use on the market. Said devices are applied on containers and make it possible to dispense their contents in pre-determined quantities. Special reference is made to measuring/dispensing devices for detergents and for products for personal and room hygiene and for pharmaceutical purposes.
Some measuring devices belonging to the known technique consist of a measuring chamber, into which the product to be dispensed enters when the container is capsized, and of a collecting chamber, into which the product is transferred from the previously filled up measuring chamber, when the container is brought back to its upright position.
The dispensing of the product occurs when the container is capsized again, when the pre-measured product flows out of the dispensing chamber, while a new quantity of product is transferred from the container into the measuring chamber. The patent for industrial invention which makes the object of the U.S. patent application Ser. No. VI92A000021 in the name of the same inventor of the present invention, describes a measuring/dispensing device, wherein the measuring chamber and the collecting chamber are obtained through fixed surfaces which intersect each other at an angle.
The presence of surfaces intersecting each other at an angle does not allow a very precise measuring, particularly when the container on which the measuring device is applied is handled too abruptly or too slowly or when only a limited amount of product is left in the container.
In order to eliminate the mentioned inconveniences the present invention has the main purpose of disclosing a measuring/dispensing device allowing the dispensing of strictly constant quantities of product, with very limited weight tolerance, even though the measuring and dispensing operations are performed abruptly or too slowly.
Another purpose of the invention is for the measuring/dispensing device to allow the dispensing of strictly constant quantities of product even when the container only holds a limited quantity thereof.
The described purposes and advantages are reached by an improved measuring/dispensing device for granular or powder products which, in accordance with the main claim, comprises: chamber holding the measured product, closed at the bottom and connected with an over-lying collecting chamber through a joining wall complete with at least one first opening; element, wherein it delimits a dispensing duct, said second element comprising a product-measuring chamber presenting an open bottom and a second opening connected with the mentioned at least one first opening of the mentioned first element; least one opening, communicating with the dispensing duct of said first element, suited to allow the dispensing of the product, slanted walls, converging toward the bottom of the element to which they belong and matching at the top and at the bottom of a same central, essentially cylindrical area. According to a preferred embodiment the second element of the device is eccentrically matched in the holding chamber of the first element and it defines within said holding chamber a dispensing duct arranged at the opposite side of the openings made laterally in said first and second elements, wherein said openings are obtained each in correspondence with at least one slanted wall belonging to the element wherein it is made.
According to a preferred embodiment the holding chamber of the first element and the overlying collecting chamber are divided into two separate zones through a vertical partition allowing also the measuring of partial quantities in relation with the total measured quantity, said partial quantities being dispensable separately or jointly, by suitably adjusting the position of the lid.
According to another embodiment the holding chamber of the first element and the overlying collecting chamber are divided into two zones through a vertical p
