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 packaged elongate intravaginal device having a longitudinal axis comprising:
a. the elongate intravaginal device; and
b. an overwrap substantially enclosing the elongate intravaginal device and having a longitudinal overlap seam disposed generally parallel to the longitudinal axis, wherein:
i. the seam includes one ply of overwrap material disposed at a first margin of a overwrap blank, an inner surface of which is superposed on an outer surface of a second ply of overwrap material disposed at a second margin of the overwrap blank, opposite the first;
ii. the overwrap has a substantially continuous line of weakness that extends from the first margin to the second margin and at least 360° around the circumference of the elongate intravaginal device;
iii. the line of weakness extends across the longitudinal overlap seam and includes weakness elements superposed in each ply of the overlap seam; and
iv. the line of weakness does not intersect itself, thereby remaining a unitary structure upon destruction of the line of weakness.
2. The packaged elongate intravaginal device of claim 1 , wherein the line of weakness originates proximate a first end of the packaged device and extends toward a second end, opposite the first, of the packaged device.
3. The packaged elongate intravaginal device of claim 1 , wherein the line of weakness is inclined about 15° to about 45° from a plane perpendicular to the longitudinal axis.
4. A packaged elongate intravaginal device having a longitudinal axis comprising:
a. the elongate intravaginal device; and
b. an overwrap substantially enclosing the elongate intravaginal device and having a longitudinal overlap seam including one ply of overwrap material disposed at a first margin of an overwrap blank, an inner surface of which is superposed on an outer surface of a second ply of overwrap material disposed at a second margin of the overwrap blank, opposite the first, the overlap seam disposed generally parallel to the longitudinal axis, wherein:
i. the overwrap has a substantially continuous line of weakness comprising open and land portions, each having a length associated therewith, disposed about the device having an angle to a plane perpendicular to the longitudinal axis of the packaged device of about 20° to about 35° ;
ii. the line of weakness originates proximate a withdrawal end of the packaged elongate intravaginal device with a ratio of open length to land length along the line of weakness of less than about 3:2 and a ratio of open length to land length along the line of weakness distal the withdrawal end of at least about 2:1.
5. The packaged elongate intravaginal device of claim 4 , wherein the ratio of open length to land length along the line of weakness proximate the withdrawal end is less than about 5:4.
