**Abstract:** Using the concept of the $\lambda $-lattice introduced recently by V. Snasel we define $\lambda $-lattices with antitone involutions. For them we establish a correspondence to ring-like structures similarly as it was done for ortholattices and pseudorings, for Boolean algebras and Boolean rings or for lattices with an antitone involution and the so-called Boolean quasirings.

**Keywords:** $\lambda $-lattice, $\lambda $-semilattice, ortholattice, $\lambda $-ortholattice, antitone involution, Boolean quasiring
