Abstract
An improved dual-seal, wide-surface roller-type dispensing package combination for cosmetics and the like. A wide-surface dispensing roller is held in place in a fitment which is adapted to be attached to the finish portion of a container for the product to be dispensed. The dispensing roller is allowed to revolve within the fitment to facilitate uniform dispensing and application of the contents of the container. The total package is completed by a closure which is adapted to snap into engagement with the container. A primary seal is formed between the dispensing roller and the fitment upon application of the closure. The closure also includes a quantity of resilient material, such as a foamed polymer, positioned to contact the dispensing roller and the fitment to form a secondary seal to prevent leakage of product when the closure is placed into engagement with the container.
