Abstract
Abstract A birth control means designed to limit sperm production by effecting a slight temperature increase in the testes comprises a scrotum insulator cut from a flat sheet of a flexible insulating material to the shape of a trapezoid. Preferably the insulating material is a moisture impervious plastic film vacuum metallized to have an infrared reflective surface. The scrotum insulator is used by being held in place around the scrotum preferably as by insertion in unmodified jockey-type shorts.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
As a scrotum insulator, (a) a sheet of flexible insulating material in symmetric trapezoidal form, the base of which is in the range of six to seven inches wide, the top of which is in the range of one and one-half to two and a half inches wide and the height of which is in the range of four and a half to five and a half inches, said base having a centrally located cutout adapted to accomodate the penis, and wherein said sheet is a moisture impervious plastic film having on one side a thin, infrared-reflective metal layer; (b) fastener means attached to the outer face thereof and adapted to secure said insulator to the undershorts of the user.
Claim 2
Dependent Claim
120 words
As a scrotum insulator, (a) a sheet of flexible insulating material in symmetric trapezoidal form, the base of which is in the range of six to seven inches wide, the top of which is in the range of one and one-half to two and a half inches wide and the height of which is in the range of four and a half to five and a half inches, said base having a centrally located cutout adapted to accomodate the penis, and wherein said sheet is a moisture impervious plastic film having on one side a thin, infrared-reflective metal layer; (b) fastener means attached to the outer face thereof and adapted to secure said insulator to the undershorts of the user.
Claim 3
Dependent Claim
42 words
The insulator of claim 1 wherein said cutout is of trapezoidal shape in the range of one and three-quarters to two and one-quarter inches at the base, three-quarters to one and one-quarter inches at the top and one-half to one inch high.
Claim 4
Dependent Claim
30 words
The insulator of claim 1 wherein said flexible insulating material is a reinforced polyethylene sheet vacuum metallized with aluminum over which aluminum is placed a thin protective clear plastic topcoat.
Claim 5
Dependent Claim
17 words
The insulator of claim 1 wherein said fastener means covers the geometric center of said outer face.
Claim 6
Dependent Claim
27 words
The insulator of claim 1 wherein said fastening means is a flexible hook tape fastener adapted to disengagably secure said insulator to the undershorts of the user.
Claim 7
Dependent Claim
119 words
As a scrotum insulator: (a) a sheet of flexible insulating material in symmetric trapezoidal form, the base of which is in the range of six to seven inches wide, the top of which is in the range of one and one-half to two and a half inches wide and the height of which is in the range of four and a half to five and a half inches, said base having a centrally located cutout adapted to accomodate the penis, and wherein said sheet is a low density, predominantly closed cell plastic foam less than three-eights inch thick; (b) fastener means attached to the outer face thereof and adapted to secure said insulator to the undershorts of the user.
Claim 8
Dependent Claim
119 words
