Abstract: A cup structure for a bra includes an outer layer (10) made of netted cotton fabric, a foam layer (20) connected to an inside of the outer layer and an inner lining (30) connected to the foam layer. The outer layer and the foam layer are flexible at all directions so as to mate with the breasts of a wearer. The cup is made to have a shape and this shape can be maintained because the flexibility of the outer layer and the foam layer.

Abstract: A casing includes a hollow rectangular main body with upper and lower walls and front and rear upright walls to define right and left openings, and two pairs of mounting seats fixed to and disposed inboard to the upright walls and extending a longitudinal direction of the upper and lower walls. A retaining member is disposed above the upper wall to define a retaining groove. Each of two side plates has a depressing force transmitting abutment portion extending from an upper edge in a transverse direction thereof, and front and rear lateral abutment portions for abutment with the mounting seats when brought to cover the openings. A cover plate is superimposed on the upper wall, and has a front cover edge and a rear cover edge insertable into the retaining groove.

Abstract: An improved combination wall is composed of a foundation member, two foam boards and two face boards. The foundation member has two wall boards spaced in a parallel manner. Located between the two wall boards are a plurality of partition boards arranged at an interval such that the partition boards are parallel to one another, and that the partition boards are perpendicular to the two wall boards, and further that both sides of each of the partition boards are fastened respectively with inner surfaces of the two wall boards. The two foam boards are fastened respectively with the outer surfaces of the two wall boards. The two face boards are fastened respectively with the outer surfaces of the two foam boards.

Abstract: A rigid PVC foam material is made from a compound containing ingredients, such as polyvinyl chloride or vinyl chloroacetate copolymer, which is mixed with 5-50 parts by weight of ethylene vinyl acetate copolymer or ionized polyethylene resin or chloro sulfo polyethylene resin, 5-50 parts by weight of acrylobutadiene rubber or acrylic butadiene-styrene rubber or isoprene or natural rubber, 1-5 parts by weight of a stabilizer, 1-30 parts by weight of a chemical foaming agent, 0.2-5 parts by weight of a bridging agent, and 1-5 parts by weight of an extrusion-aiding agent. The mixture is extruded by a rolling machine at a temperature in a range of 100-150 degrees in Celsius and is subsequently transferred to a molding tool in which it is heated under a pressure and a temperature in a range of 120-170 degrees in Celsius for 10-60 minutes so as to bring about a foaming and bridging reaction.
