Jules Montenier was an cosmetic research chemist and businessman who pioneered the use of flexible polyethylene bottles with his introduction in July 1947 of the squeeze bottle for Stopette underarm deodorant.

Beginning in 1938 Montenier was looking for a way to apply liquid deodorant directly to the skin. Working with newly developed polyethylene plastic Montenir developed an injection-molded bottle with a heat-sealed bottom. Before he could try the new bottle, he learned of a similar product made by the Plax Corp. used for the packaging of hydroflouric acid for by the General Chemical Co. Montenier worked with Plax on new bottles, testing them for a year. The result was Montenier's "hand form" 2 1/4 oz. bottle with a 20 mm neck. Stopette in the new squeeze bottle was an immediate success and led to the increased demand for polyethylene bottles for a wide array of products.
