AI Technical Summary

Benefits of technology

The Child Resistant and Senior Friendly Can Lid has several advantages. Firstly, the outer edge of the lid is tapered in and smooth, making it difficult to grip or pry off. Secondly, the lid can be tightly closed without leaving any gaps between it and the can. This helps to create a partial vacuum within the can, which prevents air from escaping and maintains the quality of the food or medicine. Thirdly, the lid is designed to be easily opened using a flexible locking tab and gripping ribs. Overall, the Child Resistant and Senior Friendly Can Lid provides a secure and effective way to protect and preserve the contents of cans.

Problems solved by technology

Another advantage of the Child Resistant and Senior Friendly Can Lid is that the outer edge is tapered in and smooth and not easy to grip or pry off.

Abstract

The present invention is directed to a can lid that is child resistant, and at the same time senior friendly, and can be initially installed on a can to be removed by an adult, especially a senior adult, and be put back on the can in the same condition where a child could still not be able to easily remove it. The child resistant and senior friendly can lid provided has a replaceable can lid and a locking member, such that when a can is initially opened, it may be readily resealed. The child resistant and senior friendly can lid has tapered, smooth sides to make the lid difficult to grasp and a sealing ledge on the inside surface to grab the seam roll of the upper edge of the can. The lid sealing ledge is relieved in two areas ninety degrees apart leaving a ridge to maintain a seal when the lid is attached to a can. The can lid will be flexible enough to bend for removal by seniors but resistant to removal by children.

Description

FIELD OF THE INVENTION[0001]This application provides a new and unique can lid for metal cans that will be difficult for children to open but adults, especially senior adults, will have the ability to open the lid and replace it and reseal the container so equipped, readily and easily. More particularly, a child resistant and senior friendly can lid is provided having a replaceable can lid and a locking member.BACKGROUND OF THE INVENTION[0002]Canning is the process of preserving a product by processing and sealing it in an airtight metal can. Cans are typically either two-piece or three-piece cans. In the case of a two-piece can, a can body is formed by punching a metal plate to form a cylinder closed at one end. The can is then filled and the open end closed by seaming a lid to the can body during the canning process. In the case of a three-piece can, a can body, open at both ends, is formed by rolling and seaming a metal plate. A first end is closed by seaming a lid to the can bod...
