Abstract: A method and system for validating a form, that includes providing, to a client, the form comprising a primary token, receiving, in response to the client loading the page form, a request for a secondary token, providing the secondary token in response to receiving the request, and receiving the form comprising the primary token and a secondary token from a client. The method further includes validating the form, where validating the form includes obtaining a first primary token hash from the secondary token, applying a first hash function to the primary token to obtain a second primary token hash, and determining that the first primary token hash and the second primary token hash match. The method further includes accepting the form upon validating the form.

Abstract: A moulded closure base includes a sidewall and a top plate. The sidewall has a retention projection having a retention surface for engaging a complementary projection on a container neck. The top plate has one or more access slots through which part of a die extends during moulding to form the retention surface.
