## Abstract

The present disclosure provides a squeeze packing having a cut surface that describes a three-dimensional curved surface shape, in which the cut surface can be temporarily held with ease and intimately attached in an accurate manner without the use of an adhesive during fitting onto a device. The squeeze packing has, on at least one arbitrary portion of an endless ring finished to predetermined dimensions, a cut surface describing a three-dimensional curved surface shape extending diagonally so as to form a predetermined angle θ with respect to a radial direction of the ring, having a substantially S-shaped profile in side view, and curving in a width direction.

## Claims

### Claim 1

A squeeze packing, comprising a ring finished to predetermined dimensions, wherein the ring has at at least one arbitrary portion thereof cut surfaces extending diagonally, so as to form a predetermined angle θ with respect to a radial direction of the ring, said cut surfaces having two non-uniform S-shaped profiles extending through the width and the thickness or diameter of the ring, the S-shaped profiles having different curvatures in each side view, and said cut surfaces having three-dimensional curved surfaces in a width direction across a front side and reverse side.

### Claim 2 (depends on 1)

A method for manufacturing a squeeze packing as claimed in claim 1, characterized in comprising:
applying a twist in at least one arbitrary portion of a ring finished to predetermined dimensions, the twist being centered about a circumferential direction axis of the ring; bending the ring in an S-shape; and cutting the bent portion diagonally, thereby forming cut surfaces extending diagonally that, when the twist is released, said cut surfaces have two non-uniform S-shaped profiles extending through the width and the thickness or diameter of the ring, the S-shaped profiles having different curvatures in each side view, and said cut surfaces have three-dimensional curved surfaces in a width direction across a front side and reverse side.
