Abstract: Improved bottles for dispensing liquid household products such as liquid detergents and fabric softeners. The package is comprised of a multilayer body in which the inner layer includes polyethylene made with a metallocene catalyst. The bottles have improved stress cracks resistance yet may be lighter then traditional bottles. They may be made by blow molding.

Abstract: A container having a lightweight bottle body resistant to stress cracking, especially useful for liquid household products such as heavy duty liquid detergents, but also for liquid fabric softeners, light duty liquid detergents, automatic dishwashing gels, chemicals, foods and other products. The light weight of the body limits the amount of resource needed to produce the body and the amount of plastic material to be disposed of when the contents have been consumed. In one embodiment, the body includes a multilayer resin structure having an inner layer which includes a metallocene polyethylene polymer. An octagonal shape, ribs or grooves at the intersections of the panels, a drainback fitment, an off center neck, and an in-mold label are optional.

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.
