Abstract
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.

An improved, dual-seal, roller-applicator dispensing package comprising, in combination: a container having a neck portion defining an opening at one end thereof for dispensing the contents thereof, said neck portion including first and second interference fit means on its outer surface; a roller-retaining fitment having a generally arcuate roller-retaining socket covering the opening of said container neck and including at least one aperture for dispensing the contents of said container and an upwardly extending lip portion, and a container-engaging flange extending downwardly from said roller-retaining socket and including a container-engaging interference fit means on its inner surface for engagement with said first interference fit means on said container neck; a dispensing roller having a major portion inserted within said roller-retaining socket of said fitment so as to be in communication with said dispensing aperture and having a minor portion extending beyond the extremity of said roller-retaining socket to define a dispensing surface; and a closure member including a top panel and a skirt portion depending from the periphery of the top panel and having a container-engaging interference fit means on its inner surface for engagement with said second interference fit means on the neck of the container, said closure member including inwardly directed means on the interior of said top panel which contacts said dispensing roller to force said dispensing roller into sealing engagement with said fitment, and a quantity of resilient foamed polymer material positioned on the interior surface of the top panel radially outwardly from said inwardly directed means on the interior of said top panel and on a portion of the interior surface of the skirt portion to contact the dispensing roller and the lip portion of said fitment to create a seal therebetween and to bias said dispensing roller into sealing engagement with said fitment to thereby create a double seal between the dispensing roller and the fitment.
