Fastener with tape

A fastener with tape comprising:

• a male member comprising a mating projection having a bulging head and a seat portion supporting said mating projection, said seat portion having a flat male surface near the base of the mating projection, and a female member comprising:
• a body having a mating hole in a center thereof, communicating with face and reverse sides, the mating hole having an approximately equal height to the mating projection of the male member and having a reduced diameter intermediate portion with its inner diameter being gradually increased toward the face and reverse sides to provide respective lead-in surfaces for said male member head, a female face surface on the face side around the mating hole, said female face surface being in contact with the flat male surface when the female member is set in engagement with the male member with its face surface side up, the maximum diameter of said female face surface being smaller than the diameter of said flat male surface of the male member, a female reverse surface on its reverse side around the mating hole, said female reverse surface being in contact with the flat male surface when the female member is set in engagement with the male member with its reverse surface side up, the minimum diameter of said female reverse surface being larger than the flat male surface of the male member;
• whereby the female member face and reverse surfaces are asymmetrical such that the female member can be engaged with the male member from either side of the female member, with a correspondingly different force of engagement which is brought about by the difference of the contact areas of the male member with the female member between when the female member is set in engagement with the male member with its face side up and when the female member is set in engagement with the male member with its reverse side up;
• and wherein said female member has at least one mold hole across which the tape at least partially extends internally thereof.
