Disclose a kind of Fluid-filled structures, such as capsule (40).Described capsule has first surface (41) and relative second surface (42), and two surfaces connect (43) to limit each limit (51 56) at periphery.Fluid encapsulated between first surface and second surface by described capsule.The part on described limit can have concave configuration, or described limit not only has concave configuration but also have convex configuration.The shape of capsule can be the pattern such as hexagon of tessellation, in order to can effectively manufacture multiple capsule. |
