Abstract
An open-ended tamper-resistant container has a flexible seal over the oven end. The tamper-resistant container is particularly suited for holding a volatile material for slow diffusion. The container has at least one free-standing rib which prevents downward pressure or squeezing on the flexible seal of the container which could otherwise rupture the seal and/or result in leakage of the material held in the container. The tamper-resistant container is suitable for independent use or use in conjunction with an electrically heated vapor dispensing apparatus.
