This invention relates to undercup insert members. More particularly, but ' not exclusively, the invention relates to undercup insert members for brassieres.

Brassieres are made with undercup wire inserts to maintain the shape of the cups. Also, the inserts provide support for the breast. The inserts have the disadvantage that the painting or paint coating can wear away and the insert can rust causing unsightly stains.

According to one aspect of this invention, there is provided an undercup insert member for a breast support arrangement, the insert member comprising an elongate curved main portion shaped to conform generally to the breast to be supported, the insert member being formed of a plastics material.

Preferably, the breast support arrangement is an article of breast supporting underwear, for example, a brassiere, although it may be another article of breast supporting clothing, such as part of a swimsuit, for example a bikini top.

Preferably, the plastics material is capable of providing support to the breast and to hold the arrangement open. Preferably, the undercup insert member is arrangeable under a cup of the breast support arrangement, and may be constructed to hold the cup open.

The main portion preferably comprises a wire, suitably an underwire.

Preferably, the main portion is sufficiently flexible to allow deformation, for example when being washed, such that the insert member can return to its original shape.

Desirably, the plastics material is a polymeric material. Preferably the plastics material is an acetal polymer, advantageously an acetal homopolymer.

Alternatively, the plastics material is an acetal copolymer. The plastics ’ material may be a resin. A suitable plastics material is sold under the trade mark

Delrin, which is a registered trade mark of E.I. du Pont de Nemours and

Company.

The plastics material may be a flexible and/or resilient material. The plastics material may be a thermoplastic polyester, a thermoplastic polyester elastomer, and/or a liquid crystal polymer. The plastics material may comprise a filler or reinforcement, which may be in the form of glass. The filler or reinforcement may comprise approximately 10% w/w of the plastics material, up to approximately 20% w/w of the plastics material or up to approximately 30% w/w of the plastics material. Suitable plastics materials may be sold under the trade marks VECTRA, CELANEX and RITEFLEX by a company Ticona.

Referring to Figs. 1 and 2 of the drawings, there is shown an undercup insert member 10 for a brassiere. The undercup insert member 10 is in the form of an underwire for a cup of a brassiere. The insert member 10 comprises an elongate curved main portion 12 formed of a plastics material, and is curved to conform to the size and shape of the breast to be supported. The insert member 10 is sewn into a hem underneath the cups of the brassiere to provide support for the breast.

The main portion 12 is formed by moulding and has a profile of a generally oval configuration. In some embodiments, the profile may be of a kidney shape.

The main portion 12 has opposite ends 14, 16 which are rounded.

The provision in the preferred embodiments of the main portion 12 having a generally oval profile and having rounded ends provide the advantage that there is a reduced risk of the insert member 10 piercing the brassiere.

The undercup insert member 10 is formed of a suitable plastics material which combines sufficient rigidity to provide support to the breast, and also sufficient flexibility to allow bending and twisting of the insert member 10 during use and washing so that it will return to its original configuration. A suitable such material is an acetal homopolymer resin, for example as sold under the trade mark Delrin, a registered trade mark of E.l. du Port de Nemours and Company.

Another embodiment of the invention is shown in Figs. 3, 3A and 3B which ' is generally similar to the embodiment shown in Figs. 1 and 2, and comprises the same features. These features have been labelled with the same reference numerals. In addition to the features shown in Figs. 1 and 2, the embodiment shown in Fig. 3 also includes flange members 18, 20 provided at the ends 14, 16 of the main portion 12. The flange members may be formed of the same } material as the main portion 12. Alternatively, the flange members can be formed of a rubberised material, which may be a rubberised version of the . material from which the main portion 12 is formed. The flange members 18, 20 allow the insert member to be sewn into the brassiere. As can be seen from Fig. 3A and 3B, the profile of the main portion 12 is generally kidney shaped.

In some embodiments, the flange members 18, 20 extend substantially the whole length of the main portion 12, as shown in broken lines in Fig. 3, and

Is designated by the numeral 22, to allow stitching along the length of the main portion 12. This would be particularly suitable for use in sports brassieres, and allows the insert member to be stitched into the brassiere substantially along the whole of the length of the main portion 12.

A further embodiment is shown in Figs. 4 to 8 which is generally similar to the embodiments shown in Figs. 1 to 3B, and comprises many of the same features. These features have been labelled with the same reference numerals.

The embodiment shown in Figs. 4 to 8 differs from those shown in Figs,. 1 to 3B in that the main portion 12 comprises two regions, a first or outer region 30, and a second or inner region 32. The insert member 10 shown in Figs4to 7 is sewn into the brassiere such that the outer region 30 is arranged adjacent the outer region of the breast, and the inner region 32 arranged adjacent the inner region of the breast. :

The outer region 30 has a profile shown in Fig. 6 which comprises first and , second opposite elongate support elements 34, 36 which are connected to each other by a connecting element 38. The connecting element 38 is of a narrower v width than the support element 34, 36 such that the profile of the outer region 30 is generally of an hour glass shape, as shown.

The provision of the outer region 30 having a profile of an hour glass shape provides the advantage that it allows the outer part to twist when the . brassiere is put on and therefore provides improved aesthetics and is more comfortable for the wearer.

As shown in Fig. 5, the outer region 32 of the main portion 12 has a profile which is generally oval in shape.

There is thus described several embodiments of an insert for a brassiere which is formed of a plastics material and the preferred embodiments of which have an oval profile and rounded ends. Thus, the preferred embodiments have the advantage that they will not rust or otherwise corrode but also, they have the advantage of overcoming a problem with prior art insert members, whereby if the coating is worn away after continuous use to reveal bare metal, there is danger of piercing the body of the wearer. Also, a disadvantage of prior art insert members is that they can be detected by metal detecting machines, for example at airports causing embarrassment to the wearer. The provision of and undercup insert member formed of a plastics materials overcome such problems.

Various modifications can be made without departing from the scope of the invention, for example the main portion could have a generally circular profile.

In addition, the insert member could be used in other forms of breast supporting underwear, or in swimsuits.

It will be appreciated that the dimensions and sized of the insert member will vary depending upon the size of the breast to be supported by the brassiere. ' Whilst endeavouring in the foregoing specification to draw attention to those features of the invention believed to be of particular importance it should be understood that the Applicant claims protection in respect of any patentable feature or combination of features hereinbefore referred to and/or shown in the drawings whether or not particular emphasis has been placed thereon.
