The consumption of drinks packaged in metal cans with separation or displacement opening (environmentally friendly) does no offer adequate hygienic protection in that the can may become contaminated by the outside surface of the lid that the liquid must necessarily contact (during consumption). Further risks come from the lips contacting the lid and from the openng profile when the drink is being sipped directly from the can.

The SHES (Safe Hygienic Easy Simple) system will overcome of these deficiencies by adopting an integrated dispenser, tied inside the can to the removable part of the lid.

In this improved can, pulling the opening lever not only opens the can, but also pulls the dispenser toward the outside thus implementing a solid leak-proof connection between the dispenser and the lid.

In terms of industrial fabrication, this innovative container can be easily manufactured with only minor changes or additions to the existing manufacturing lines already developed for the production of existing cans.
The innovation is environmentally friendly, with no impact on the environment thanks to the dispenser being built with the same material of the can and lid, or a compatible material, allows for a full recycle of the can after use.

Its adoption represents a moderate increment of the total costs while allowing conspicuous advantages in terms of hygiene, safety, and convenience.
