  • Patent number: 11432595
    Abstract: A cup, a mold and an underwear are disclosed. The cup includes an upper surface layer, a lower surface layer and a nipple-exposure prevention layer. The upper surface layer is provided with an inner concave portion, the nipple-exposure prevention layer is arranged in the inner concave portion, and the upper surface layer is arranged towards a side far away from a breast. When the lower surface layer of the cup is closely attached to the upper surface layer, and the lower surface layer is contacted with a nipple, the nipple-exposure prevention layer is capable of preventing a nipple on a female breast from being prominent.

  • Publication number: 20140057529
    Abstract: A brassiere cup support and method of manufacturing the support and cup therewith. The support comprises a plastic support in the shape of one or more of an underwire, an uplifting panel, a reinforcing pad, a sternum region, or an extended fish bone like pattern capable of providing desired “firmness” or “hardness” along its length and thereby providing desired degrees of support therealong. The plastic support comprises at least one layer of polymer and at least one layer of a second material, wherein the at least one layer of polymer and the at least one layer of the second material are in the form of a sandwich. Preferably, the plastic support comprises at least two layers of polymer and at least one layer of the second material, with an adhesive applied therebetween to secure the layers to one another.

  • Publication number: 20080073811
    Abstract: A method of forming a brassiere cup with a flexible plastics support feature includes providing a mould for forming the brassiere cup with a trough where the support feature is to be formed, laying down in the mould material from which the brassiere cup is to be formed such that some of the material extends into the trough, locating plastics material upon the material that extends into the trough so as to partially fill the trough with plastics material, and applying heat sufficient to soften the plastics material such that the plastics material consolidates into a desired shape as defined by the shape of the trough.
