 Silgan's KS2 offers solutions to issues that have plagued home and office delivery bottle users, fillers, and re-fillers. It is molded of a proprietary blend of resins that resist cracking and features a pierceable shell design that virtually eliminates spillage. Closure also incorporates a flow-in closure liner for a superior bottle seal and a tamper-evident band to ensure product safety.

A unique feature of the KS2 is its pierceable shell. It incorporates a series of radiating perforated leaves that open when the bottle is installed, but remain attached to the cap and are removed with the cap when bottles are returned for refilling. This eliminates the potential for cap pieces remaining in the bottle where they can become lodged in refillers’ bottle cleaning equipment and cause work stoppages or delays. They also tend to reclose when the bottle is removed from the base, reducing the potential for spillage of any water remaining in the bottle.

Whereas most existing bottle closures incorporate a rigid foam liner to seal the closure to the bottle, the KS2 employs a flow-in liner that is injected following molding. This flexible liner conforms to any irregularities in the neck of the bottle that may have been created through repeated use, ensuring a complete seal even to an uneven surface.

The closure itself, molded of a proprietary blend of resins, is more flexible and resistant to cracking than existing closures. This makes cracking of closures and subsequent leaking much less likely during shipping, handling, and installation of bottles. The KS2 also incorporates a tamper-evident band that assures users that the water has not been opened prior to delivery.

A pull-tab molded into the closure skirt makes removal easier and ensures complete removal. This benefits bottle fillers by making removal prior to cleaning and refilling more efficient.
