Tampon overwrap
View Patent ↗A packaged elongate intravaginal device has an overwrap substantially enclosing the device. The overwrap has a longitudinal overlap seam disposed generally parallel to the longitudinal axis. The seam includes one ply of overwrap material disposed at a first margin of a overwrap blank superposed on a second ply of overwrap material disposed at a second margin of the overwrap blank, opposite the first. The overwrap has a substantially continuous line of weakness that intersects a plane including the longitudinal axis of the packaged device at at least three unique locations. The line of weakness extends across the longitudinal overlap seam and includes weakness components superposed in each ply of the overlap seam, and the line of weakness is arranged and configured in a manner to permit the overwrap to remain as a unitary structure upon destruction of the line of weakness.
1. A method of opening an overwrap enclosing an elongate intravaginal device having a longitudinal axis comprising the steps of:
a. grasping an insertion end and a withdrawal end of the overwrap, the overwrap having a circumference and a substantially continuous line of weakness disposed about the device, the line of weakness extending in a straight line completely about the circumference of the overwrap and having an angle to a plane perpendicular to the longitudinal axis of the packaged device of about 20° to about 35°;
b. rupturing the line of weakness while maintaining the unitary structure of the overwrap;
c. removing the withdrawal end of the overwrap from the elongate intravaginal device;
d. grasping the withdrawal end of the elongate intravaginal device;
e. removing the overwrap from the insertion end of the elongate intravaginal device; and
f. inserting the elongate intravaginal device into a vagina.
2. The method of claim 1 , wherein the step of rupturing the line of weakness comprises twisting the ends of the overwrap in opposite directions about the longitudinal axis.
3. The method of claim 1 , wherein the step of rupturing the line of weakness comprises bending the ends of the overwrap perpendicular to the longitudinal axis.
4. The method of claim 1 , wherein the step of rupturing the line of weakness comprises pulling the ends of the overwrap in opposite directions along the longitudinal axis.
5. A method of sealing the dome end of a tampon overwrap comprising the steps of:
a. forming a tubular overwrap having a circumference with a longitudinal seam, a first end of the tubular overwrap corresponding to a withdrawal end of the tampon, a second end of the tubular overwrap corresponding to the dome end of the tampon, and a line of weakness extending in a straight line toward the second end of the tubular overwrap in a first direction at an angle of between about 15° to about 45° from a plane perpendicular to the longitudinal seam and extending completely about the circumference of the tubular overwrap;
b. closing the first end of the tubular overwrap by folding over and sealing a portion of the tubular overwrap;
c. inserting a tampon into the tubular overwrap; and
d. closing the second end of the tubular overwrap by:
i. twisting excess tubular overwrap material is extending beyond the dome end of the tampon in the first direction; and
ii. folding the excess tubular overwrap material toward the first end of the tubular overwrap and conforming the excess tubular overwrap material to the dome end of the tampon.
6. The method claim 5 , wherein the first direction is clockwise.
7. The method claim 5 , wherein the first direction is counterclockwise.
