Abstract
Abstract A molded, internally threaded fastening device adapted for receipt of a threaded member. The fastening device is molded in a generally flat position with two preferably joined complementary sections adapted to be manually folded over upon one another, in face-to-face relationship, to form the fastener. Each complementary section defines a generally concave cavity extending along the complementary face which will cooperate with the concave cavity in the complementary face of the other complementary section to define a generally axially extending threaded member receiving bore when the two complementary sections are folded over upon one another. Each concave cavity includes molded internal thread portions on the concave surface thereof which are adapted to cooperate and register with the molded thread portions in the other cavity to form a continuous internal thread along at least a part of the threaded member receiving bore. Each complementary section also includes at least one convexly extending loop which in connection with the concave cavity defines a substantially circular aperture. When the complementary sections are folded over upon one another, or are in the preassembled position, the apertures will form a portion of the threaded member receiving bore through which the threaded member must pass.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
150 words
A molded, one-piece, internally threaded, threaded member receiving fastener, said fastener being molded in two joined, complementary sections each having a complementary face adapted to be manually folded over upon the other to form a preassembled fastener, each of said complementary sections comprising: a generally concave cavity extending along the complementary face and intersecting at least one periphery of said face, said cavity adapted to register with the cavity in the other complementary section when the sections are folded face-to-face to define a threaded member receiving bore, said cavity having molded thread portions on the concave surface thereof which will register with the molded thread portions in the other concave cavity to form a substantially smooth internal thread in the threaded member receiving bore, and at least one loop extending convexly from said face, said loop being substantially coaxial with said cavity and partially defining said threaded member receiving bore.
Claim 2
Dependent Claim
150 words
A molded, one-piece, internally threaded, threaded member receiving fastener, said fastener being molded in two joined, complementary sections each having a complementary face adapted to be manually folded over upon the other to form a preassembled fastener, each of said complementary sections comprising: a generally concave cavity extending along the complementary face and intersecting at least one periphery of said face, said cavity adapted to register with the cavity in the other complementary section when the sections are folded face-to-face to define a threaded member receiving bore, said cavity having molded thread portions on the concave surface thereof which will register with the molded thread portions in the other concave cavity to form a substantially smooth internal thread in the threaded member receiving bore, and at least one loop extending convexly from said face, said loop being substantially coaxial with said cavity and partially defining said threaded member receiving bore.
Claim 3
Dependent Claim
27 words
The fastener of claim 1 wherein each of said complementary sections additionally comprises loop receiving depressions to receive the loops convexly extending from the other complementary face.
Claim 4
Dependent Claim
18 words
