A separable fastening device having first and second separable members wherein the first member has a surface of upstanding spear-like protuberances extending from one broad surface of its base and the second member has a surface of complementary engaging elements. The spear-like protuberances are characterized by the property that when the first and second separable fastener members are pressed into face-to-face relationship the spear-like protuberances on the first separable member penetrate the surface of the second separable member and engage the complementary engaging elements of the second separable member and resist separation parallel to the interfacial plane of engagement but are readily separable by peeling forces applied substantially normal to this interfacial plane. The first separable member having a surface of spear-like protuberances has particular utility as part of a separable fastener having reticulated urethane foam as the second complementary member, however it also provides a superior fastening device when used with a second separable member having a surface of complementary engaging elements in loop form. |
