Abstract
Official abstract text for this publication.
The tube is stretchable. The tube is stretched by applying tension in a longitudinal direction. The tube returns to its short state by releasing the above-described tension applied in the longitudinal direction. A plurality of protrusions are formed on an inner surface of the tube. Each of the plurality of protrusions extends in a circumferential direction. The plurality of protrusions are arranged side by side in the longitudinal direction of the tube. A pitch of the protrusions is less than or equal to 1.5 μm.
First claim
Opening claim text (preview).
What is claimed is: 1. A stretchable tube, wherein a plurality of protrusions extending in a circumferential direction are formed side by side on an inner surface in a longitudinal direction, and wherein a pitch of the protrusions is less than or equal to 1.5 μm, wherein an outer circumferential portion made of polysiloxane, wherein the protrusions are formed of a silicon compound having a larger number of oxygen atoms than polysiloxane. 2. The tube according to claim 1 , wherein heights of the protrusions are changeable depending on a tension applied in a longitudinal direction. 3. The tube according to claim 1 , further comprising: an inner circumferential portion which has the protrusions and is formed of the silicon compound.
