Abstract
Abstract A cup is molded from two layers of stretchable materials by molding first the crown portion, inverting the materials and then molding the remainder of the cup. The resulting cup has a non-stretchable crown portion, a substantially non-stretchable longitudinal cup portion and a unitary multidirectional stretchable periphery portion. A pair of these cups are used to form a unique brassiere wherein the base layer forms a unitary cup, support frame and torso-encompassing portion.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
93 words
A method of making a brassiere cup from two layers of stretchable material comprising: attaching a first layer of stretchable material to a second layer of stretchable material; molding a first area of said first layer and juxtaposed portion of said second layer with one of said layers contacting a heated male mold to form the crown of the cup; and molding a second area of said first and second layers including said first area with the other of said layers contacting a heated male mold to form the remainder of the cup.
Claim 2
Independent Claim
93 words
A method of making a brassiere cup from two layers of stretchable material comprising: attaching a first layer of stretchable material to a second layer of stretchable material; molding a first area of said first layer and juxtaposed portion of said second layer with one of said layers contacting a heated male mold to form the crown of the cup; and molding a second area of said first and second layers including said first area with the other of said layers contacting a heated male mold to form the remainder of the cup.
Claim 3
Dependent Claim
27 words
The method according to claim 1 wherein said step of attaching includes sewing said first layer to said second layer along the periphery of said first layer.
Claim 4
Dependent Claim
27 words
The method according to claim 1 wherein said step of attaching includes bonding said first layer to said second layer along the periphery of said first layer.
Claim 5
Dependent Claim
36 words
The method according to claim 1 wherein said second layer contacts said mold during the crown molding step and said first layer and portions of said second layer contact said mold during the cup molding step.
Claim 6
Dependent Claim
22 words
The method according to claim 1 wherein said second layer is sufficiently larger to form the support frame for said molded cup.
Claim 7
Dependent Claim
34 words
The method according to claim 1 wherein said first layer is substantially triangular and forms almost all of the lower portion of the cup and substantial portions of the upper portion of said cup.
Claim 8
Dependent Claim
30 words
The method according to claim 1 wherein said first area is sufficiently stretched and heated during the two molding steps to form a dual layer cup having a nonstretch crown.
Claim 9
Dependent Claim
31 words
The method according to claim 7 wherein said second area is sufficiently stretched and heated during the cup molding step to form a dual layer cup having substantially no longitudinal stretch.
Claim 10
Dependent Claim
48 words
The method according to claim 1 wherein said crown molding step includes securing said first area of said first layer and juxtaposed portion of said second layer about the periphery thereof to limit the stretching to said first area and stretching said first area over a male mold.
Claim 11
Dependent Claim
45 words
The method according to claim 9 wherein said cup molding step includes securing said second area of said second layer larger than said first area about the periphery thereof to limit stretching to said second area and stretching said second area over a male mold.
Claim 12
Dependent Claim
17 words
The method according to claim 10 wherein two different male molds are used in the molding steps.
Claim 13
Dependent Claim
30 words
The method according to claim 10 wherein the same male mold is used in both molding steps with the layers being drawn over said male mold to two different depths.
Claim 14
Independent Claim
109 words
A method of making a brassiere cup from two layers of stretchable material comprising: attaching a first layer of stretchable material having an area less than the total area of the to-be-formed cup to a second layer of stretchable material; molding a first area including a substantial portion of said first layer and juxtaposed portion of said second layer with one of said layers contacting a heated male mold to form the crown of the cup; and molding a second area of said first and second layers including said first area with the other of said layers contacting a heated male mold to form the remainder of the cup.
Claim 15
Independent Claim
109 words
A method of making a brassiere cup from two layers of stretchable material comprising: attaching a first layer of stretchable material having an area less than the total area of the to-be-formed cup to a second layer of stretchable material; molding a first area including a substantial portion of said first layer and juxtaposed portion of said second layer with one of said layers contacting a heated male mold to form the crown of the cup; and molding a second area of said first and second layers including said first area with the other of said layers contacting a heated male mold to form the remainder of the cup.
Claim 16
Independent Claim
111 words
A method of making a brassiere cup from two layers of stretchable material comprising: attaching a first layer of stretchable material having an area less than the total area of the to-be-formed cup to a second layer of stretchable material; molding a first area including a substantial portion of said first layer and juxtaposed portion of said second layer with one of said layers contacting a first heated male mold to form the crown of the cup; and molding a second area of said first and second layers including said first area with the other of said layers contacting a second heated male mold to form the remainder of the cup.
Claim 17
Independent Claim
111 words
A method of making a brassiere cup from two layers of stretchable material comprising: attaching a first layer of stretchable material having an area less than the total area of the to-be-formed cup to a second layer of stretchable material; molding a first area including a substantial portion of said first layer and juxtaposed portion of said second layer with one of said layers contacting a first heated male mold to form the crown of the cup; and molding a second area of said first and second layers including said first area with the other of said layers contacting a second heated male mold to form the remainder of the cup.
Claim 18
Dependent Claim
32 words
The method according to claim 14 wherein said first male mold has the shape of the crown of the cup and said second male mold has the shape of a complete cup.
