Weatherchem Corp.: Dispensing closure redesign

Weatherchem’s Flapper® dispensing closure has been redesigned.

Pw 3629 Webweatherchem
The closure is available for the 53-485 size and in the following dispensing options: .100/Pour, .100/.300, and Tri/Pour. Designed to dispense dry foods like spices and grated cheese as well as pet and chemical products. Now sift resistant (SR), it can be used without a liner when using an external shrink-band and shipping upright. It also eliminates the old sift hole cleanouts and adds a concaved sift surface--making the lid easier to close by eliminating product build-up. A wider thumb-indent and a larger, deeper depressing lip makes it easier to open. Offers a modern look with a glossy finish and easy-to-read graphics.
