ABSTRACT:
A push-pull dispenser is shown having a base portion, an upwardly extending neck portion, a stem extends upwardly from the neck and has at least one stem lug depending from an upper portion of the stem. The stem lug may have four sides including an upper tapered or beveled surface and a lower horizontal surface. The push-pull dispenser also comprises a slidable dispensing cap disposed over the stem and at least one folding finger extending upwardly from a lower portion of the slidable dispensing cap. The at least one folding finger has an upper horizontal surface which engages the lower horizontal surface of the stem lug and inhibits resultant forces which typically cause slidable dispensing caps to deflect.
