Revolutionary, yet familiar

XO is the new, innovative relock system for beverage cans. While new and revolutionary, the XO opening will still feel familiar to everybody: the XO resealable can opens like a traditional SOT (Stay-On-Tab) can, yet it includes what the SOT is missing: the ability to be relocked. Opening the XO-equipped can is an easy, intuitive and one-handed procedure. It’s the Relock Revolution for all canned beverages.

Seal breaking & Venting

Smooth laminar liquid flow

The XO System is not only the Relock Revolution for beverage cans, but it also improves the entire drinking experience. While opening the XO System, the self-sealing XO Internal Relock Disc is pushed down diagonally towards the liquid. When the can is brought to the mouth and tilted, the liquid flows around the disc in a wavelike movement – the socalled “laminar flow.” The hole under the XO Pull Tab, used for venting during the opening process, operates as an air inlet. This results in a greater and smoother flow rate and pouring speed. As the XO Slider is made of plastic material, the drinking sensation is entirely different from traditional aluminum cans: The can doesn’t feel steelcold against the lips, and there are no sharp edges. The clean surface and the smooth laminar pour provide an unprecedented experience.

The on-the-go solution

By pushing the XO Slider back over the mouthpiece and pushing the XO Pull Tab back down, the can is relocked: The reason why we invented the system and call it the Relock Revolution. The XO System safely contains and preserves the beverage and its carbonation for freshness at a later time. It also protects it from insects, dirt, and spillage. The XO System passes through several processes invisible to the user to achieve this: the XO Slider inside the can releases the XO Internal Relock Disc into its "closed" position. In addition, the exterior XO Slider covers the mouthpiece and seals the freshness inside. The instantly relocked can is leak-proof and the perfect portable solution.

Relocking the can: first, move the XO Slider back over the mouthpiece.

Visible safety

The XO System fully meets the beverage industry’s shelf life standards. To ensure the freshness of the product, it is necessary to indicate to brands, retailers and consumers alike that the beverage can is in its original, untampered delivery condition and has not been previously opened. XO has integrated a smart solution with the well visible XO Tamper-Proof Band – a biaxially-oriented PP band welded to the XO Pins. When initially opening the can, the XO Tamper-Proof Band breaks. When relocking the XO System, the band disappears behind the XO Pull Tab. There‘s no littering because the band will always remain connected to the can.



If the can has not been opened before, the Tamper-Proof Band remains unbroken on top of the XO Pull Tab.



During the initial opening, the Tamper-Proof Band is broken by lifting the XO Pull Tab.

XO production facilities

During the development of the XO System, an efficient and adaptable production process was the only objective. XOLUTION, in collaboration with experienced partners, installed in 2013 the first production line in Austria. It was all in one place: injection molding of the plastic parts, debagging and stamping of the shells, assembling and finishing of the final XO End, extensive testing and quality control and packaging of our end product: a fully automatic and standardized process with adaptability to larger capacities of different diameters in defined regions.

In May 2017 the second production line for the next generation of XO ends started in Czech Republic with an annual capacity of 200 mio. XO Ends. Further assembly lines will follow in the near future.

Cans demand quality

Cans are successful because they are resistant to various temperatures, pressure and other infl uence. This is the challenge we had to meet. We developed a broad test program to meet all the requirements. Within the production process we constantly perform online and offline tests for all steps of the injection and assembly processes.

Shell Standards

XO Ends are based on industry standard shell platforms. Xolution works with all major Global Can Makers and the customer has the choice of which shell base he wants to use. There is no limitation in Shell profile or Shell diameter. Therefore there is no need to adjust chucks or rolls in the seamer for similar styles (B64, CDL+/E, ISE, OLOF, Super End)
