Promising Packaging Patents January 2014
Light-barrier package

Light-barrier packageProtective container displays light-sensitive products (shown)
Transparent containers such as bottles and jars have a coating that reduces light transmission through the container and offer a viewing area or window to make the product and its actual color visible to a consumer or purchaser. The containers are useful for protecting photo-sensitive products while allowing the color of those products to be displayed to the user.

It is claimed to be especially applicable in protecting light-sensitive or light-curable products, including cosmetics, from the effects of environmental light exposure during storage or while merchandised.

A-B InBev's vented can lid improves pouring
Anheuser-Busch InBev has filed a patent that relates to improvements in a double-opening system for beverage cans. Specifically, the patent describes methods for two openings in the lid of a beverage container or can: a primary or pour opening for the liquid and a secondary vent opening to allow air into the can while liquid is flowing from the primary opening. Key aspects include a lid, a pour panel defined by a pour score in the lid and a vent panel defined by a vent score in the lid.

IML label adds oxygen barrier to retortable containers
The invention addresses the need for new in-mold labeled (IML) containers that have good oxygen barrier properties and that can be retorted. The processes involve setting into a mold a multilayer label having an oxygen barrier layer and injecting a melted resin suitable for forming a container. The process forms a container with an oxygen barrier layer; it is optimized when the multilayer label has at least one oxygen-absorbing resin layer containing ethylene-vinyl alcohol copolymer, has an oxygen absorbent and the container is retortable.

A closure with a 3D seal prevents leaks
In this update, inventor/CEO Aron James Clarkson of the Star One Group in the U.K. discloses the latest status concerning a patent-pending closure that prevents leaks for chemical containers and other package types that relies on a form-fitting seal. He claims that the larger, 3D surface area of the seal becomes far more effective than for a normal container and closure.
