Abstract
An athletic protector, such as an athletic cup, with regions formed of the same compositional material, which is more rigid in one such region than in another such region.
Claims17
An athletic cup comprising a first region and a second region, the first region and the second region being formed of the same compositional material, wherein the first region is more rigid than the second region.
An athletic cup comprising
- a frontal region formed of a compositional material characterized by a first density;
- and
- a resilient comfort edge formed of the compositional material characterized by a second density, which second density is different from the first density.
A method of manufacturing an athletic cup molded from a single compositional material comprising:
- providing a granulated compositional material;
- injecting a first portion of the compositional material into a mold preheated to a frontal region forming temperature under a first pressure and exposing the first portion of the compositional to the frontal region forming temperature and first pressure for a first time period;
- injecting a second portion of the compositional material into a mold preheated to a resilient comfort edge forming temperature under a second pressure, and exposing the second portion of the compositional material to the resilient comfort edge forming temperature and the second pressure for a second time period;
- bringing the mold containing the frontal region into contact with the mold containing the resilient comfort edge;
- joining the frontal region with the resilient comfort edge by exposing the molds to a fusing temperature at a third pressure for a third time period.

An athletic cup molded from a single compositional material comprising:
- (a) A frontal region comprising:
- (i) granular ethylene vinyl acetate copolymer with a density of about 70 kg/m3,
- (ii) a convex outer surface with an apex that is about one-half (0.50) to one (1.0) centimeters thick,
- (iii) a concave inner surface;
- (iv) and a volume sufficient to enclose the wearer's genitals;
- (b) a resilient comfort edge wherein a distance between the outer surface and the inner surface at an apex is between about one-half and one centimeters;
- (c) a resilient comfort edge adapted to contact a wearer's skin, comprising ethylene vinyl acetate copolymer with a density of about 40 kg/m3.
