Ice pack

Abstract

This product is an ice pack used, for example, for cooling the human body. As shown in the reference diagram, this product consists of a lid, a ring, an inner cylinder, and an outer cylinder. The inner cylinder shown in the reference diagram can contain, for example, ice or water. The inner cylinder can have the ring attached to the annular recess at the top. The ring can be connected to the inner circumferential surface of the cylindrical part of the lid. The outer circumferential surface of the cylindrical part of the lid can be connected to the inner circumferential surface of the outer cylinder. The outer cylinder is positioned to cover the inner cylinder. The surface of the outer cylinder has a pattern formed of multiple roughly diamond-shaped depressions, and this pattern is formed continuously in the circumferential and axial directions of the outer cylinder. This pattern not only has a decorative effect, but also improves the grip of the outer cylinder and is expected to have an anti-slip effect during use.
