James Alexander Corp.: Radius seal for plastic ampoules

The specially-engineered radius seal provides a stylish, finished look to the product. The glass-free ampoule is comprised of a one-piece molded polyethylene or polypropylene unit that remains intact and sealed until activated by the user. Activation is accomplished instantaneously with a gentle squeeze of the package. This breaks an inner plastic membrane that seals in the contents prior to use. Another gentle squeeze then dispenses the product.
