Abstract
An interference fit is effected for a threaded closure cap used in mounting a trigger sprayer onto the threaded neck of a container by the provision of an oversized elastomeric gasket seal presenting at least one radially extending protrusion bent by the cap during the cap threading operation to lie between the cap and the container neck, the protrusion having a predetermined thickness to form the interference fit for increasing resistance to cap backoff.
