Abstract
Official abstract text for this publication.
A pressure tank unit may include: a tank including a container space which contains compressed gas; and a plurality of protectors bonded to a surface of the tank, wherein the tank may include: a body part having a cylindrical shape; and a dome part provided at an end of the body part and having a hemispherical shape, the plurality of protectors may be arranged along a boundary between the body part and the dome part in a circumferential direction of the tank, each of the plurality of protectors may have a first portion covering the dome part and a second portion covering the body part, and an inner surface of the second portion facing the body part may include at least one bonding area bonded to the body part via a bonding material.
First claim
Opening claim text (preview).
What is claimed is: 1 . A pressure tank unit comprising: a tank comprising a container space which contains compressed gas; and a plurality of protectors bonded to a surface of the tank, wherein the tank comprises: a body part having a cylindrical shape; and a dome part provided at an end of the body part and having a hemispherical shape, the plurality of protectors is arranged along a boundary between the body part and the dome part in a circumferential direction of the tank, each of the plurality of protectors has a first portion covering the dome part and a second portion covering the body part, an inner surface of the second portion facing the body part comprises at least one bonding area bonded to the body part via a bonding material, and the at least one bonding area comprises a first bonding area and a second bonding area, wherein the first bonding area and the second bonding area are independent of each other. 2 . The pressure tank unit according to claim 1 , wherein the first bonding area and the second bonding area are aligned along the circumferential direction. 3 . The pressure tank unit according to claim 2 , wherein a groove is defined between the first bonding area and the second bonding area in the inner surface of the second portion. 4 . The pressure tank unit according to claim 1 , wherein an inner surface of the first portion which faces the dome part comprises a protrusion protruding toward the dome part, and the inner surface of the first portion is in contact with the dome part at the protrusion and faces the dome part via a clearance at a portion other than the protrusion. 5 . A pressure tank unit comprising: a tank comprising a container space which contains compressed gas; and a plurality of protectors bonded to a surface of the tank, wherein the tank comprises: a body part having a cylindrical shape; and a dome part provided at an end of the body part and having a hemispherical shape, the plurality of protectors is arranged along a boundary between the body part and the dome part in a circumferential direction of the tank, each of the plurality of protectors has a first portion covering the dome part and a second portion covering the body part, an inner surface of the second portion facing the body part comprises at least one bonding area bonded to the body part via a bonding material, and an inner surface of the first portion which faces the dome part comprises a protrusion protruding toward the dome part, and the inner surface of the first portion is in contact with the dome part at the protrusion and faces the dome part via a clearance at a portion other than the protrusion.
