Claims17
An absorbent tampon comprising a mass of absorbent material which has been compressed into a generally cylindrical, self-sustaining form in a transverse dimension and in a longitudinal dimension, wherein subsequent to compression the generally cylindrical, self-sustaining form comprises a maximum transverse dimension of less than 13 millimeters, wherein the tampon has a syngyna absorbent capacity of between about 6 and about 9 grams, and wherein the tampon undergoes a growth, upon fluid absorption, in the transverse dimension of at least 7 millimeters according to the dynamic expansion test, and in the longitudinal dimension.
An absorbent tampon comprising a mass of absorbent material which has been compressed into a generally cylindrical, self-sustaining form in a transverse dimension and in a longitudinal dimension, wherein subsequent to compression the generally cylindrical, self-sustaining form comprises a maximum transverse dimension of less than 13 millimeters, wherein the tampon has a syngyna absorbent capacity of between about 6 and about 9 grams, and wherein the tampon has an average expansion rate in the transverse dimension of greater than 1.7 millimeters per minute after absorbing 3 grams of sheep's blood at a rate of about 1 gram per minute according to the dynamic expansion test, and wherein the tampon undergoes growth, upon fluid absorption, in the longitudinal dimension.
An absorbent tampon comprising a mass of absorbent material which has been compressed into a generally cylindrical, self-sustaining form in a transverse dimension and in a longitudinal dimension, wherein subsequent to compression the generally cylindrical, self-sustaining form comprises a maximum transverse dimension of less than 14 millimeters, wherein the tampon has a syngyna absorbent capacity of between about 9 and about 12 grams, and wherein the tampon undergoes a growth, upon fluid absorption, in the transverse dimension of at least 7 millimeters while under a contained pressure of 0.25 psi according to the dynamic expansion test and in the longitudinal dimension.
