Various other features, objects, and advantages of the invention will be made apparent from the following description taken together with the drawings.
The present disclosure is described with reference to the following Figures.
The present application relates to garments, and more specifically to garments having a pair of absorbent breast cups, which are capable of absorbing bodily fluids such as breastmilk or sweat. Examples of such garments are bras, camisoles, swimsuits, and other similar upper torso garments including integral breast cups or adapted to receive insertable breast cups. The upper torso garments can be any size, shape, or style, which details are not limiting on the scope of the present disclosure.
As noted, the exemplary embodiment of the disclosure requires that the absorbent terry cloth 4 is fully laminated on its inner and outer faces 41, 42 to the one-way transport material 3 and the foam 5, respectively. In one example, the absorbent terry cloth 4 is fully laminated to the one-way transport material 3 and to the foam 5 using hot melt spray glue. Fully laminating the absorbent terry cloth 4 to the one-way transport material 3 controls the movement of liquid through the layers because they are in direct contact with one another across the entire inner face 41 face of the absorbent terry cloth 4. Full lamination of the outer face 42 of the absorbent terry cloth 4 to the inner face 51 of the foam 5 ensures that a majority of the liquid is absorbed by the absorbent terry cloth 4 before the liquid absorbs into the foam 5. In other embodiments, the absorbent terry cloth 4 may be laminated only at an outer edge 43 thereof to the one-way transport material 3 and the foam 5; however, this may result in less controlled movement of the liquid from the one-way transport material 3 to the absorbent terry cloth 4, as the two layers would be able to move (e.g., float, slip, or slide) with respect to one another.
It is a feature of the preferred embodiment that the layer of absorbent terry cloth 4 has an outer edge 43 that does not extend to the outer edge 33 of the one-way transport material 3 nor to the outer edge 53 of the foam 5 when the layers 3, 4, 5 are centered with respect to one another (i.e., aligned one on top of the other with their perimeters being concentric) such that the absorbent terry cloth 4 is fully enclosed between the one-way transport material 3 and the foam 5 around its entire perimeter. This way, liquid that is absorbed by the absorbent terry cloth 4 is sealed within the breast cup 2, 2′ by the adhesive in the bonded edge of the breast cup 2, 2′, where the outer edge 33 of the one-way transport material 3 is bonded directly to the outer edge 53 of the foam 5. In some embodiments, the outer edge 43 of the absorbent terry cloth 4 is spaced inwardly from the respective outer edges 33, 53 of the one-way transport material 3 and the foam 5 by a predetermined offset 11. When the foam 5 is laminated to the absorbent terry cloth 4 and to the outer edge 33 of the one-way transport material 3, the one-way transport material 3 is bonded directly to the foam 5 across an entire width of the predetermined offset 11. In one example, the predetermined offset 11 has a width between about 0.5 cm and 1.5 cm. Note that the predetermined offset 11 may have roughly the same width around the entire perimeter of the breast cup 2 as shown in
In an instance in which the breast cup is a floating breast cup 2 meant for insertion into the bra 200 of
In one example, the method 700 includes sizing and shaping the absorbent terry cloth 4 such that the outer edge 43 of the absorbent terry cloth 4 is spaced from the outer edge 33 of the one-way transport material 3 by a predetermined offset 11 when the absorbent terry cloth 4 is centered on the one-way transport material 3. Optionally, the inner layer of foam 5 has the same size and shape as the one-way transport material 3, and the inner face 51 of the foam 5 is bonded directly to the outer face 32 of the one-way transport material 3 that extends beyond the outer edge 43 of the absorbent terry cloth 4 across an entire width of the predetermined offset 11. In another example, the one-way transport material 3 has an outer edge 33 that extends beyond that of the outer edge 53 of the foam, and the outer edge 33 of the one-way transport material 3 can be folded over the outer edge 53 of the foam 5 and bonded or stitched to the foam 5 within the predetermined offset 11.
In one example, the method 700 further comprises orienting the absorbent terry cloth 4 in the breast cup 2, 2′ such that the inner face 41 of the absorbent terry cloth 4 is smooth and the outer face 42 of the absorbent terry cloth 4 is fleecy.
In one example, the method 700 further comprises using hot melt spray glue to laminate the inner face 61 of the water-resistant material 6 to the outer face 52 of the foam 5, to laminate the inner face 51 of the foam 5 to the outer face 42 of the absorbent terry cloth 4 and to the outer edge 33 of the outer face 32 of the one-way transport material 3, and to laminate the inner face 41 of the absorbent terry cloth 4 to the outer face 32 of the one-way transport material 3.
In one example, in the molded breast cup 2, 2′, the absorbent terry cloth 4 is fully enclosed between the one-way transport material 3 on the inner face 41 thereof and the foam 5 and the water-resistant material 6 on the outer face 42 thereof.
Returning to
The layer of absorbent terry cloth 4 can be any appropriate terry material. In one example, the layer of absorbent terry cloth 4 is capable of absorbing at least 500%, and in some examples at least 570%, of its initial weight in water. In one particular example, a 5.67 square-inch sample of the absorbent terry cloth 4 can absorb on average about 7.5 milliliters of water. The layer of absorbent terry cloth 4 can be a double- or single-sided terry. The layer of absorbent terry cloth 4 can be French terry fabric, with the non-flat side being maintained as longer loops of yarn or being shredded to create fleece. In a preferred embodiment, the absorbent terry cloth 4 is a French terry, wherein the inner face 41 of the absorbent terry cloth 4 is smooth and the outer face 42 of the absorbent terry cloth 4 is fleecy. In one particular example, the layer of absorbent terry cloth 4 is weft-knit French terry, the non-flat side of which has been shredded to form fleece, made of 84% cotton (30S), 16% polyester (10S) having a weight of 340 gsm. In this configuration, the liquid is wicked away from the smooth inner face 41 of the absorbent terry cloth 4 toward the more absorbent fleecy outer face 42. In one example, the absorbent terry cloth 4 is treated on the outer face 42 with a chemical that causes the material to pull liquid away from its inner face 41 and thereafter prevents the liquid from returning to the inner face 41 of the material. In another example, the absorbent terry cloth 4 is a two-layer bonded terry or fleece fabric, the non-flat (e.g., fleecy) side of which is treated with a water-absorbent finish.
The layer of foam 5 can be any foam capable of providing a suitable padding according to the style of the bra 100, 200. In a preferred embodiment, the layer of foam 5 is an open-cell stretch foam having an element of water affinity.
The bras 100, 200 and breast pads 2, 2′ are washable and reusable without losing their functionality, such as their wicking capabilities, absorbency, water-resistance, breathability, shape, and construction integrity.
