Silgan Closures has launched its new one-piece 55 mm KS2 plastic closure for five-gallon and three-gallon Home and Office Delivery (HOD) water bottles.
Molded of a proprietary blend of resins that resists cracking, the closure reportedly features a pierceable shell design that virtually eliminates spillage. The KS2 also incorporates a flow-in closure liner for a superior bottle seal and a tamper-evident band to ensure product safety.
The KS2 closure 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 could eliminate 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 could reclose when the bottle is removed from the base, reducing spillage.
The KS2 reportedly 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 is reportedly molded of a proprietary blend of resins. This could make it flexible and resistant to cracking than existing HOD closures, which could make cracking of closures and subsequent leaking less likely during shipping, handling and installation of bottles.
The KS2 reportedly incorporates a tamper-evident band that assures users that the water has not been opened prior to delivery. It reportedly requires less resin to mold, in keeping with Silgan Closures’ ongoing commitment to environmental responsibility, and it can run on existing application equipment without major changes.
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.
