Modification project of a closure currently in use on the market (35×18 aluminum capsule with spice dispenser), with one having the same aesthetic characteristics but which allows the consumer to extract the plastic dispenser that remains inside the glass when he has finished the product, this to differentiate the two pieces without the aid of tools that could harm the health of the consumer (tips, knives or other).

Since this is a capsule with a guarantee seal obtained on the aluminum body, it is not necessary to have a guarantee seal also on the plastic insert inside it, we thought of designing a piece with the same shape as the current dispenser but with characteristics different functional.

In practice, the dispenser will have an external crown consisting of two semi-circles connected to the central pourer by two bridges of one millimeter and a “joist” of about five millimeters, the latter in addition to connecting the two semi-circles to the central pourer, has the fulcrum function for lifting the two semicircles. .

When the pourer has to be extracted from the glass, the consumer will have to lift the two half circles by breaking the two one-millimeter bridges and keeping the two half-circles facing upwards, he will have to exert a traction that will allow the doser to be extracted from the glass container.

An important aspect of this project is that it will allow adequate separation of glass and plastic components, facilitating correct separate collection by the final consumer.


The fundamental element of novelty is the possibility of totally and easily separating the container (glass) from the dispenser (plastic) at the end of use without the aid of tools that can compromise the health of the consumer.

The capsule must be as compatible as possible with the bottling plants used by customers.

The possibility of extracting the dispenser from the glass at the end of use makes it possible to make the recyclability of the container completely manageable.
