Wearable article having elastic belt
Disclosed is a wearable article comprising a main body and a ring-like elastic belt comprising a front belt and a back belt. At least some of the elastic bodies may be arranged in an array, the array defined as meeting: a) one array is formed by 2-10 elastic bodies; b) each elastic body within one array is disposed in an inner-interval between each elastic body of 2-4 mm; and c) one specific array disposed in an extra-interval between at least one neighboring elastic bodies outside the specific array of greater than the inner-interval. Further, the front belt may comprise at least 5 arrays.
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.
2. The absorbent article of claim 1 , wherein all of the elastic bodies disposed in the front belt are arranged in the at least 3 arrays.
3. The absorbent article of claim 1 , wherein the elastic bodies of the one array has a density of no more than 940 dtex.
4. The absorbent article of claim 1 , wherein the elastic belt comprises no more than 60 elastic bodies.
5. The absorbent article of claim 1 , wherein the article has a Waist Circumference Force according to the Whole Article Force Measurement herein of no more than 10 N.
6. The absorbent article of claim 1 , wherein all of the elastic bodies disposed in the front proximal tummy zone are arranged in concentrated arrays.
7. The absorbent article of claim 6 , wherein the tensile stress of the front leg zone is no more than 50% of the tensile stress of the front proximal tummy zone.
8. The absorbent article of claim 7 , wherein the tensile stress of the back leg zone is no more than 100% of the tensile stress of the back proximal tummy zone.
9. The absorbent article of claim 1 , wherein the tensile stress of the front distal tummy zone is lower than the tensile stress of the back distal tummy zone.
10. The absorbent article of claim 1 , wherein at least a portion of the elasticity of at least one of the elastic bodies is removed in the region overlapping with the front and back waist panels of the main body.
11. The absorbent article of claim 1 , wherein the elastic bodies of the array are disposed at an elongation of from 100% to 350%.
