Containers for holding materials

This invention describes a container with an outer, rigid shell made from recycled or biodegradable paper pulp, and an inner, flexible bag that holds the contents. The outer shell includes a specific feature, such as a hole, tab, or perforation, designed to help a user easily separate the shell from the inner bag. This separation feature also allows for at least partial destruction of the outer container, making it simpler to manage after use.

Why it matters: The core challenge remains the cost-effective production of durable, moisture-resistant pulp shells that can compete with established plastic alternatives. While sustainability trends continue, no specific technological shift in pulp material or manufacturing has fundamentally altered this balance in the past two years.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom pulp shell and molding
