Latest Patents

Kawakami's latest patents include innovative designs for can-shaped containers. One patent describes a can comprising a barrel, an upper lid, and a lower lid bonded to the barrel. Both lids feature a gas liquid impermeable barrier layer, preferably aluminum foil, along with resin layers heat fused to both sides. The design incorporates a tab and score on the upper lid, which is engineered to prevent breaking when the can is dropped by ensuring the yield strength of the top lid is greater than that of the lower lid. This differential strength is achieved by varying the thickness of the barrier layer between the two lids.

Another patent focuses on a cover for a can that consists of a multi-layer base of aluminum foil sandwiched between heat-fusible resin layers. The outer resin layer is designed with an inner section and a surrounding outer section, separated by a smooth, continuous gap. This innovative design allows for better stress distribution over the multi-layer base, enhancing the overall durability of the can.
