  • Heat and pressure resistant bottle with increased oxygen barrier and method of production
    Patent number: 8136331
    Abstract: This invention provides a bottle that allows for easy and efficient application of shrink sleeves. The ease of application is partly a result of the invention's wall thickness along its body-forming portion. The body-forming portion of the invention has thick walls and thus exhibits negligible expansion during a hot-filling process. This permits a shrink sleeve to be placed onto the body-forming portion of the resistant bottle prior to filling. If the resistant bottle is hot-filled, the sleeve shrinks as a result of radiant heat emanating outwardly from the high temperature product, without the aid of an external heat source, such as a heat tunnel.
