Ringless Metal Cans and Method - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240010395 titled 'Ringless Metal Cans and Method

Simplified Explanation

The abstract describes a patent application for a can design that includes a can body and a lid. The can body is made from a single piece of material and has an edge that defines a top opening. It also has an inwardly directed bead that extends around the body and defines a sealing surface of constant dimension. The lid has an outwardly directed sealing surface that abuts the inwardly facing sealing surface of the bead to seal the lid to the can body.

• The can body is made from a single piece of material and has a top opening defined by its edge.
• The can body has an inwardly directed bead that extends around its body and defines a sealing surface.
• The lid has an outwardly directed sealing surface that seals the lid to the can body by abutting the inwardly facing sealing surface of the bead.
• An alternative can body design has a pinched or collapsed bead that defines an upwardly facing sealing surface for engagement with a downwardly facing sealing surface of a can lid.
• The alternative can body design also includes an inwardly directed bead between the can body edge and the pinched or collapsed bead.
• The lid's outer brim is designed to be retained between the two beads of the alternative can body.

Potential Applications:

• Food and beverage packaging
• Pharmaceutical packaging
• Industrial product packaging

Problems Solved:

• Provides a secure and reliable seal between the can body and lid
• Simplifies the manufacturing process by using a single piece of material for the can body

Benefits:

• Enhanced product freshness and preservation due to the effective seal
• Cost-effective manufacturing process with reduced material and labor requirements
• Improved consumer experience with easy-to-open and resealable cans

Original Abstract Submitted

a can comprises a can body () and a lid (). the can body is manufactured using only a single homogeneous piece of material and has an edge that defines a top opening into the can. the can body also has an inwardly directed bead (), which extends around the body, is adjacent to the can body edge, and defines an inwardly facing sealing surface () of substantially constant transverse cross-sectional dimension along an axial extent. the lid defines an outwardly directed sealing surface which abuts the inwardly facing sealing surface presented by the inwardly directed bead in order to seal the lid to the can body. an alternative can body has an inwardly directed pinched or collapsed bead which defines an upwardly facing sealing surface () for engagement with a downwardly facing sealing surface of a can lid. the alternative can body additionally has an inwardly directed bead () between the can body edge and the pinched or collapsed bead. an outer brim () of the lid is configured to be retained between the two beads of the alternative can body.
