FIELD OF THE INVENTIONThe present invention relates to improvements to a bra and related methods of its construction.
BACKGROUND TO THE INVENTIONBras of a kind which are made from a plurality of layers or plies of material which have been subjected to molding and trimming are known. Molded bras offer the benefit of convenient construction since the materials used lend themselves conveniently to the introduction of a three dimensional cup shape to define the breast cups of a bra by a molding device. Such a device is normally a molding press having appropriately shaped mold portions (an upper and lower mold portion) intermediate of which a pre-form planar ply or assembly of plies of materials can be placed whereupon the molding press can then introduce the three dimensional shape into the plies.
This process avoids the time consuming steps of creating a three dimensional cup form by the more traditional method of stitching together a plurality of panels of material, each cut to an appropriate perimeter shape. Whilst speed of production is an important factor to the manufactures of such bras, aesthetics and comfort factors are also important as these will distinguish the final product from competing products, at the point of sale.
Some of the materials used in the known molded forms of bras, lend themselves to being subjected to heat (and/or adhesive) to allow for such materials to be bonded to other material of the bra. This allows for an assembly of plies of material of a bra to be laminated together. It has however been an issue in respect of bras of the molded kind, to ensure that the perimeter of the bra is capable of being defined in a robust manner. Perimeter stitching or overlooking ensures that the perimeter remains in tact and is not subjected to fraying over a reasonable life span of the bra. Perimeter stitching usually involves the provision of a hem by some of the plies of the bra about the perimeter which is then stitched onto itself to define a hem about part of or all of the perimeter of the bra. Alternatively a separate piping like hem may be stitched about the perimeter.
However, stitching or overlooking can be a time consuming step in the manufacturing of a bra. It also requires accuracy in the stitch line in order for the appearance of the bra to remain attractive. Furthermore stitching can be prone to becoming undone or damaged resulting in the integrity of the perimeter of the bra being affected. The stitching itself and the material of the bra immediately adjacent to the stitching can also cause comfort issues to the wearer of a bra. Discomfort to a wearer is an undesirable result of a bra. Therefore the provision of stitching or overlooking to the perimeter of a bra can be undesirable.
Accordingly it is an object of the present invention to provide a bra which addresses the abovementioned disadvantages or which will at least provide the public with a useful choice.

BRIEF DESCRIPTION OF THE DRAWINGSThe present invention may be considered to consist in the foregoing and examples of which have been described with reference to the accompanying drawings in which:
With reference to the accompanying drawings there is shown in
The hem shown in
Where reference herein is made to inward and outward or similar terminology, it is meant be understood to be in relation to the body of the wearer of the bra. For example, the “innermost” or “inner side” is the face side of the bra that is closer to the body of the wearer than the outward portions of the bra.
The fully assembled bra of the present invention is preferably of a kind which incorporates a ply or plies of foam material within the breast cups 3, 4 but which does not include such foam materials within at least a substantial part of the chest band region 5. However, the present invention also applies to fabric only hemmed seamless bras, as shown in
In the following description a bra is referred to. However, it should be apparent that the same construction could form part of another garment such as an evening gown or a swimsuit.
Preferred construction details of the bra of
The hem 8 is preferably only of a width W sufficient to securely and permanently engage the exterior most ply 9 of the bra to the inside (concave side) face of the bra. The hem 8 may for example be between 4-12 mm in width. It preferably extends along the perimeter of the bra which may be defined as the outer perimeter line (or outer edge) 10, the lower perimeter line (or lower edge) 11 and the neckline perimeter (or neckline) 12 of the bra. Indeed the hem 8 is preferably continuous across the entire neckline 12 for both breast cups 3, 4 extending over the bridge region 14 between the adjacent breast cups 3, 4.
For further details of the assembly of preferred materials to define the bra of the present invention reference will now be made to the preferred method of its manufacture.
With reference to
The precursor core assembly 15 is introduced into a molding press consisting of a male mold portion 18 and a female mold portion 19 as for example shown in
Captured between the second foam ply 24 (and any other plies that may be associated therewith) is preferably an underwire assembly 25. The underwire assembly 25 is shown in plan view in
It is located intermediate of the second foam ply 24 and the then molded precursor core assembly 15A at a location corresponding to the breast cup form 20 being the lower region of the breast cup form where such an underwire assembly 25 would normally be provided as part of a bra. Molding of the components (as shown in
The excess material of the then molded precursor core assembly 15A and the then molded and laminated second foam ply 24 may then be cut to be removed from the breast cup form 20 to define the assembly as shown in
The next step in the manufacture of the bra of the present invention is to take one or for example both breast cup core assemblies 28 and laminate to their concave side, a ply of fabric material (the interior most ply 33). With reference to
The interior most ply 33 is preferably of a material such as nylon or spandex.
A vertical cross section through the then molded assembly of the breast cup core assemblies 28 and the interior most ply 33 is for example shown in
The next stage is for a wing shaped panel (wing panel 35) to be placed onto the interior most ply 33 and in part over the flange 29. The wing panel 35 is preferably of a plan shape corresponding to the wing portion of the chest band region 5 of the bra. It is positioned onto the interior most ply 33 in a location where the chest band region 5 of the bra is to be provided in part by the interior most ply 33. The wing panel is placed onto the same side of the interior most ply 33 as where the breast cup core assembly 28 is provided. The wing panel 35 is made from a rigid film material which may have some flexibility. It is preferably slightly sticky or adhesive on one side (that side to engage with the interior most ply 33) and not adhesive on the other side. In one method of the present invention it is provided to prevent any bonding of any other of the layers of the bra provided at this region to the interior most ply 33 on that side thereof where the wing panel 35 is located (other than the hem 8). In this one aspect the wing panel is made from a heat resistant material. In a second aspect, the material need not be heat resistant.
In the first aspect of the method of the present invention the heat resistant wing panel 35 is made from a heat resistant material which is of a kind which may be transparent and non-elastic. The plastic material will not melt below a temperature of for example 180 degrees Celsius. As this temperature will not be reached during the first method of manufacturing of the bra, the heat resistant material will not permanently bond with the plies of material immediately adjacent thereto.
In both the first and second methods of the invention utilising the wing panel, and as will be explained further on, the wing panel will be removed from the bra by hand.
The interior most ply 33 may be trimmed to cutaway excess material of the interior most ply 33 by cutting parallel (preferably along) the perimeter line of the wing panel 35 and (if not already done so before the wing panel was applied) at least part of the perimeter of the breast cup core assembly. Such cutting is for example demonstrated in
The provision of the wing panel 35 also allows for more accurate dimensioning of the shape of the wing portion of the bra during cutting. This is so because the plies defining the wing portions of the bra do not contain foam or any other shape consistent material and the wing portions are therefore too soft and elastic to be worked on (i.e. cutting accurately). The provision of the wing panel can reduce the dimensional deviation from approximately 2-3 centimetres to only 3 millimetres on average. It also may be provided for the purposes of allowing more convenient working of the material for the subsequent steps of the manufacturing of the bra.
The result of such cutting may define an assembly as for example shown in
From here the next step is preferably to apply the clasps or catches or taches to the distal ends of the interior most ply 33 of the bra. Preferably the clasps 38 are adhered by an adhesive and/or heat and/or ultrasonic welding to the interior most ply 33. As can be seen with reference to
The next stage in the method of manufacturing the bra of the present invention is to prepare the exterior most ply for the bra.
Whilst reference herein has been made to the interior most ply and the exterior most ply, the terms interior and exterior in this regard relate to the plies of material which are outermost on the bra. Reference to the interior most ply is not a ply located within the assembly of materials but is the ply of material which is to be adjacent most the body of the wearer. The outer most ply is the ply of material of the assembly of the bra which in a substantial part, is distal most from the body of the wearer.
Preparation of the exterior most ply 9 may in a first preferred method, involve the use of a template 40. The template 40 may for example be a substrate of a paper or card like material. Drawn or depicted on the template 40 is an outline of at least the lower perimeter line 11 and outer perimeter line 10 of the final form of the bra. This is as for example shown in
This material is sticky on the side facing the template 40 so that it can adhere to the template 40. Applied over the heat resistant plaster 43 is an assembly of layers the first consisting of an adhesive coated tape and the second band of elastic material although the band of elastic material is optional. It may also be optionally provided at wing portions only. The adhesive coated tape is provided at the assembly of this additional layer of tape away from the heat resistant plaster 43. The band of elastic material is provided to adhere to the heat resistant plaster 43. This may be by a suitable adhesive which can result in the sticking of this additional assembly of tape to the heat resistant plaster yet be able to be removed therefrom at a later stage. Glue is applied on the non-sticky side of the heat resistant material so that the elastic band can temporarily stay on the heat resistant material. One side of the adhesive coated tape is sticking on the elastic band. The whole of the template 40 (with the heat resistant plaster, the elastic band and the adhesive coated tape on top of it) is then placed on the thermal pressing machine as is shown in part in
The tape is of a kind which is adhesive on each side. The adhesive applied on both sides of the tape will melt when heated during the process of the manufacture of this bra enabling two plies of material of the bra to be bonded together by the adhesive coated tape. The adhesive coated tape is preferably also slightly elastic and can therefore provide mild elasticity to the material that is bonded. One example of an adhesive coated tape of this kind will result in the adhesive melting slightly at around 120 degrees Celsius. However at around 150 to 160 degrees Celsius the adhesive will completely melt and provide strongest adhesion ability. Normally the adhesive coated tape is supplied from the manufacture where one side of the tape is pre-covered with a non-stick paper which is peeled away for the purpose of exposing the adhesive coated tape for subsequent heat bonding.
The elastic band with which the adhesive coated tape engaged, is of a kind which may for example be one commonly used in garments or bras. The adhesive tape on both sides of the elastic band allows the exterior most ply to be attached to the interior most ply with the elastic band between the two plies along the perimeter of the bra. No stitching is required to affix the elastic band in the bra.
With reference to
The exterior most ply 9 may be of a material such as nylon or spandex or lycra.
The exterior most ply 9 is thereafter trimmed about the tape portions now present (being the second adhesive coating over the elastic band and the then bonded adhesive coating between the elastic band and the fabric) to the outer and lower perimeter line disposed regions thereof. Prior to the application of the exterior most ply 9 to the other components of the bra, the exterior most ply 9 has introduced therein, molded relief provided by a molding device of a kind as for example shown in
At some stage the exterior most ply 9 may have introduced therewith apertures 58 at a region of the exterior most ply 9 to correspond with the distal ends of the chest band region 5. The apertures 58 may be defined by cutting, such a ultrasonic cutting, laser cutting or physical cutting or any other suitable method. The assembly 36 and the then molded and in part trimmed exterior most ply 9A as shown in
While the apertures 58 as hereinbefore described are provided on the exterior most ply, they can equally be provided on the interior most ply to allow captured clasps to protrude through the interior most ply instead of the exterior most ply. In a preferred form, captured eyes protrude through the apertures on the exterior most ply, while captured hooks protrude through the apertures on the interior most ply. The other way around is also possible.
An alternative to the first preferred method described above for applying the assembly 44 to the exterior most ply 9 by the use of a template, will now be described. Rather than applying the tape as described with reference to
The tape may be applied by a device which consists of two surfaces at least one of which is a wheel and in between which the ply 9 can be fed. The two surfaces pinch together and can also draw therein between the tape for it to be pressure applied to the exterior most ply 9. One or both of the wheels may also include heating elements or the wheel may be heated for example to allow application of heat and pressure (see for example
Prior to the application of the exterior most ply, the exterior most ply may also be subjected to further steps of providing visually appealing appearance thereto. Such may be by a laser cutting or by stitching to have a lace or an embroidered appearance applied to the exterior most ply.
With reference to
In a first method of the present invention in respect of the use of the heat resistant wing panel, the application of heat occurs by an iron onto preferably the entire wing portion of the bra as it exists at this stage. As a result of the provision of the heat resistant panel, no bonding of the exterior most ply 9 (other than its hem) occurs with other regions of the assembly 36 at this stage. No iron heat will be applied to the cup regions of the bra at this stage but only to the wing regions. As such the exterior most ply 9 can be peeled back from the assembly 36 as for example shown in
Since the wing regions of the chest band 5 do not incorporate any material of significant rigidity (i.e. they preferably do not incorporate any foam material) it may be difficult to manipulate the wing panel regions of the various plies of material of the bra for the purposes of the steps of assembly of the bra. It may be for this reason that the wing panel 35 is employed during the assembly of the present invention. The wing panel is of a material which although flexible has some structural rigidity. Such structural rigidity allows for the outer perimeter line 10 and lower perimeter line 11 at the wing regions of the bra to be and remain clearly defined. It also provides a significantly rigid edge along the part of the outer and lower perimeter lines 10, 11 of the bra at the wing region of the chest band region 5. In a first aspect of the method involving the wing panel, allowing the folding of the hem 8 and the bonding of the hem 8 to the interior most ply 33. Without the heat resistant wing panel 35 being provided during the assembly of the bra it may make it difficult, without special devices other than an iron, to accurately define the hem. This is not so for the perimeter defined by the breast cups since these consist of a number of layers which create a more rigid edge for the exterior most ply to fold about. It may also make it difficult for the hem to be folded about the outer and lower perimeter line defined by the assembly 36. In a second method of the invention relating to the use of the wing panel, the wing panel has at this stage already been removed. Such removal has occurred before the folding of the hem 8 is to occur at the wing region of the interior most ply 33. Rather than utilising an iron for adhering the exterior and interior most plies at the wing region together to define the hem 8, a more accurate device for creating the hem is utilised. Since there is no heat resistant panel intermediate of the interior and exterior plies the use of an iron may result in the bonding of the interior and exterior plies together other than at a hem region. The device that may be utilised for merely applying heat and pressure at the hem region is a device as for example shown in
With reference to the first method of the invention involving the wing panel (where the wing panel is a heat resistant wing panel remaining in place during the formation of the hem 8 at the wing portion of the bra), the wing panel requires to be removed once the hem has been formed. As such a method of removal of the wing panel is required. It is for this region that the neckline perimeter of the bra is also not simultaneously bonded at its hemline when the outer and lower perimeter line disposed hem 8 of the exterior most plies are affixed. A subsequent affixing of the hem 8 at the neckline of the breast cup forms allows prior to such affixing, the removal of the heat resistant wing panel.
However as mentioned earlier in the specification substantially the entire perimeter of the bra may have a hem provided. As such, once the heat resistant wing panel has been removed it is then possible for the hem 8 at the neckline perimeter 12 of the bra to be affixed. A trimming of excess material of the exterior most ply 9 can occur to follow substantially the neckline perimeter of the assembly 36. However again a margin beyond the neckline perimeter 12A of the assembly 36 may be provided to the neckline edge 12B of the exterior most ply 9. This margin is preferably the same as the margin of the hem 8 to be provided at the neckline perimeter of the bra. A material like that of the tape 42 which is or includes the adhesive coated tape can be applied to the neckline perimeter 12B of the exterior most ply for its subsequent folding of the hem 8 of the exterior most ply 9 about the neckline perimeter 12A of the assembly 36. The application of the adhesive coated tape to the hem region 8 of the exterior most ply 9 at the neckline perimeter may also include the application of an elastic band like that incorporated in the outer and lower perimeter lines 10 and 11 of the bra.
A further reason for not applying any adhesive coated tape to the neckline perimeter of the exterior most ply prior to the exterior most ply having been molded by the bullet molder, is that the neckline perimeter would be very proximate to the regions of the exterior most ply 9 at where the surface relief is molded into the exterior most ply 9 by the bullet molder. As such the neckline perimeter of region of the exterior most ply during such molding will be subjected to heat and if an adhesive coated tape were applied at this point in time the effectiveness of the adhesive coated tape for subsequent use may be affected.
A pre-folded condition is as for example shown in
A further advantage that is obtained from a subsequently defined hem 8 at the neckline perimeter 12 of the bra is that any variations, deviations or inaccuracies in the location of the exterior most ply 9 to the assembly 36 can be taken into consideration at the subsequent trimming of the neckline perimeter region of the exterior most ply 9. Such subsequent trimming can ensure that a taught exterior most ply 9 is provided over the assembly 36 of the bra. Were the neckline perimeter 12 of the exterior most ply 9 trimmed at the stage where the exterior most ply 9 has its outer perimeter line 10 and lower perimeter line 11 trimmed (see
The hem 64 may be provided around the entire perimeter of the bra or around only a portion of the perimeter.
At each chest band end, the outer ply 62 extends beyond the inner ply 61 and is folded back to cover the hook and eye tapes. The hooks and eyes protrude through slits 72 and 73 on the outer ply 62 to the exterior.
In this way, the base portions of the hooks are laminated with the outer ply, either directly or indirectly through the hook tape.
The eye tape 66 is similarly installed.
While the present invention has been described with reference to particular embodiments thereof, it will be understood that such embodiments are susceptible of modifications and variations without departing from the scope of the present invention and that the invention will include all embodiments falling within the scope of the appended claims.
