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 distal edges;
wherein at least some of the elastic bodies disposed in the front belt are arranged in at least 3 arrays, the at least 3 arrays meeting a), b), and c) as follows:
a) one array is formed by 2-10 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 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 each of a select number of the at least 3 arrays is a concentrated array that meets requirements a) and b), each concentrated array being disposed at an extra-interval in the longitudinal direction from an adjacent array, wherein the extra-interval is a distance greater than the inner-interval;
wherein all of the elastic bodies disposed in the at least three arrays 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;
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 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; and
wherein the concentrated array is disposed in the front proximal tummy zone.
