A recently filed patent (Publication Number: US20230166884A1) describes a new design for a can container. The container consists of a can lid and a can body. The can lid has a disk-shaped panel portion with a circular score line on the outer edge, defining a region for forming a drinking opening. The lid also includes a groove portion connected to the panel portion, a rivet portion adjacent to the score line, a tab for opening, and a flange portion connected to the groove. The panel portion is inclined outward between the score line and the groove.

The can body is cylindrical and includes a fixing portion that is fixed to the flange portion of the lid. It also has a tapered portion between the body portion and the fixing portion, with a reduced diameter towards the fixing portion. The can body is filled with an effervescing content and has a positive internal pressure. The ratio between the diameter of the score line and the inner diameter of the body portion is specified to be between 0.6 and 0.8.

In addition to the above claims, the patent also mentions that in the tapered portion of the can body, the ratio between the inner diameter of the end portion on the fixing portion side and the inner diameter of the end portion on the body portion side should be set to 0.75 to 0.9. Furthermore, the can lid may include a convex portion on both the score line side and the can body side of the panel outer peripheral portion.

This patent application introduces a new design for a can container that aims to improve the drinking experience. The inclined panel portion of the lid and the tapered portion of the can body are designed to enhance the effervescence of the content inside the can. The specific ratios mentioned in the claims indicate the desired dimensions for optimal performance. The inclusion of convex portions on the lid adds to the overall design and functionality of the container.

It is important to note that the information provided is solely based on the claims of the filed patent and does not include any additional context or details.
