Abstract:
A container closure includes a utensil formed of a first polymer material, and a lid formed of a second polymer material, the utensil being detachably adhered to the lid by a chemical bond between the first and second polymer materials in the absence of any adhesive or bonding agent. A method for making the closure comprises the steps of introducing a quantity of a first polymer material into a mold to form a utensil, transferring the utensil from the first mold into a second mold or structurally modifying the first mold, and introducing a quantity of a second polymer material into the second mold or modified first mold to form a lid in such a manner that the utensil is detachably adhered to the lid by a chemical bond between the first and second polymer materials in the absence of any adhesive or bonding agent.
