ABSTRACT:
A roll-on applicating package is described which is adapted to dispense products incorporating a liquid which has a very low surface tension. The liquid tends to penetrate mechanical seals and migrate to outer surfaces of ordinary applicating packages, creating an unsightly appearance and a negative tactile impression. The package of the present invention includes a means to establish a primary seal and includes, within its closure, an absorptive insert adapted to make continuous contact with a lip surrounding the applicating roller when the package is sealed. The insert is made of a non-hygroscopic material which possesses an ability to draw the liquid into its exterior by capillary action. Because of the preferential migration of the liquid into the insert, outer surface fouling of the package is obviated.
