Reclosable aluminum cans aren’t new. But they have failed to gain widespread adoption on a regional or national scale. SNSTech, LLC plans to change that. The Austin, Texas-based company has developed SipNShut, a reclosable aluminum beverage can that it says meets the practical needs of all stakeholders involved: The reclosable design caters to today’s on-the-go, conscientious consumers; helps beverage brands stand out on the retail shelf; and meshes with the existing production capabilities of beverage can manufacturers.

The patented design of SipNShut features a wide mouth aperture with a sliding function that allows the consumer to easily open and close the can. It uses a standard can shell with a rivet in the center. Attached to the rivet is a triangular metal shutter with a food-safe thermoplastic resin coating that seals the opening of the can. Between the shutter and end panel is a rotating finger lever. The consumer pushes the lever to the left to break the seal of the can. When the consumer pushes the lever back to the right, the lever catches on the shutter and pulls it along to open the mouth of the can. The lever can be moved back to the left, moving the shutter to reclose the can. The opening of the can features a patented air channel to vent into the headspace to ensure smooth liquid flow and drinkability without splattering.

“It’s liquid tight once you open it and reclose it,” says Chris Schorre, chief marketing officer for SNSTech. “So if you tip the can over, if you put it in your backpack or something like that, it’s designed not to leak.”
