1. An absorbent article, comprising:
a main body and a ring-like elastic belt comprising a front belt and a back belt, wherein the front belt is joined to a front waist panel of the main body, and the back belt is joined to a back waist panel of the main body, wherein the front and back belts each having a left side panel and a right side panel, and wherein transverse edges of the front belt and the back belt are joined by first and second seams to form a waist opening and two leg openings;
wherein each of the front belt and back belt formed by a plurality of elastic bodies running in the transverse direction sandwiched between an inner sheet and an outer sheet; each front belt and back belt having transversely continuous proximal and distal edges, the proximal edge being located closer than the distal edge relative to the longitudinal center of the article;
wherein each of the proximal edges and the distal edges of the front belt and the back belt are substantially parallel, the longitudinal length of the back belt being longer than that of the front belt, wherein the distal edge of the front belt is aligned with the distal edge of the back belt, and the proximal edge of the front belt is not aligned with the proximal edge of the back belt;
wherein all of the elastic bodies disposed in the back belt are arranged in at least 5 arrays, the at least 5 arrays meeting a), b), and c) as follows:
a) one array is formed by 2 elastic bodies;
b) each elastic body within the one array (of clause a) above) is disposed in an inner-interval in the longitudinal direction between each elastic body of 2-4 mm; and
c) one specific array, outside of and separate from the one array, disposed in an extra-interval in the longitudinal direction between at least one neighboring elastic bodies outside the specific array of greater than the inner-interval;
wherein all of the elastic bodies disposed in the front and back belts extend in the transverse direction substantially parallel to each other;
wherein the entirety of the length of the belt side edge of the front belt is seamed with a certain length of the belt side edge of the back belt to define a seam length LS; and
wherein the front and back belts are each divided into 4 zones extending in the transverse direction and defined by its location from the distal edge to the proximal edge relative to the percentage of the seam length LS wherein 0-25% is the waist zone, 25-50% is the distal tummy zone, 50-85% is the proximal tummy zone, and 85-100% is the leg zone.
