Description

BRIEF DESCRIPTION OF DRAWINGS

(1) FIG. 1 depicts a front view of an embodiment in accordance with the present invention of a washable, reusable garment for retention of body fluids when worn on a person's lower body part;

(2) FIG. 2 is a top view, taken in the direction of line 2-2 of FIG. 1, and looking down toward the crotch portion of the garment of FIG. 1; and

(3) FIG. 3 is a sectional view of the crotch portion of the garment of FIG. 1 taken along line 3-3 of FIG. 1.

DESCRIPTION

(4) As used here, certain terminology is for convenience only and is not to be taken as a limitation on the invention. For instance, words such as upper, lower, left, right, top, bottom, side, horizontal, vertical, back, front, upward, and downward merely describe the configuration shown in the Figures. It is understood that the components may be in any direction and the terminology, therefore, should be understood as encompassing such variations unless specified otherwise.

(5) The terms elastic and stretchable include any material which can be stretched, and which tends to return to its original shape when relaxed.

(6) By the term seamless is meant that the body portion of the garment is free of seams in the back, the front, and the sides.

(7) By the term barrier film is meant a film that prevents or retards movement of liquid, such as blood and/or urine.

(8) With reference now to the Figures, whenever possible, the same reference numerals and letters are used throughout to refer to the same or like parts.

(9) More specifically, shown in FIG. 1 is a front view of a washable, reusable garment 10 for retention of body fluids when worn on a person's lower body part. The garment 10 is useful as an incontinence garment, a menstrual garment, a training garment, a diaper, and the like.

(10) The garment 10 may be constructed of various materials that are woven, non-woven, or combinations thereof, and may optionally include a moisture wicking agent. Cotton, nylon, and/or polyester, and/or blends thereof are suitable materials. Nylon is a particularly suitable material. Also polyester is a particularly suitable material, and more particularly suitable is an interior top cloth of polyester to which a moisture wicking agent has been applied, such as in a dye bath. Various such moisture wicking agents are known in the art. It is also desirable that the garment 10 should be appropriately elastic and/or stretchable so as to provide a snug fit about the wearer's lower body part.

(11) The garment 10 has a body portion 20 and a crotch portion 30. The body portion 20 has a waist opening W, and is seamless. By seamless is meant that the body portion is free of seams in the back, the front, and the sides, such seams being common to undergarments, and often being undesirable as the seams create panty lines that are often visible through the wearer's outer garment, such as slacks. The body portion 20, together with the crotch portion 30, forms the first and second leg openings L1, L2.

(12) FIG. 2 is a top view of the garment 10 taken looking down in the direction line 2-2 of FIG. 1, and toward the crotch portion 30. FIG. 3 is a sectional view of the crotch portion 30 taken along line 3-3 of FIG. 1.

(13) As can be seen, on the inside of the crotch portion 30, there is sewn or otherwise attached a pocket 40, adapted for receiving a removable absorbent pad AP in a space S defined by the pocket 40. The absorbent pad AP may be disposable or reusable, and optionally may be provided with a pull tab T for facilitating removal of the absorbent pad AP from the pocket 40. More particularly, the pocket 40 has two edges 60 and 70, which suitably may be incorporated into the garment 10 at or near the leg openings L1, L2. The back end 110 of the pocket 40 is closed by being sewn or otherwise attached to the garment 10, and the front end 120 of the pocket 40 is left open for receiving the absorbent pad AP.

(14) On the inside of the pocket 40 is included an absorbent composite 140, for absorbing body fluids, such as urine, blood, menstrual flow, et cetera. The absorbent composite 140 may be sewn, or otherwise attached to the pocket 40. The absorbent composite 140 may be constructed of various materials that are woven, non-woven, or combinations thereof, and may be any absorbent material that is suitable for when the garment 10 is washed. One suitable material for the composite 140 is a non-woven fabric of a polyester/rayon blend. One such suitable polyester/rayon blend is commercially available under the trade name, HYDREX. More preferably, the composite material, such as HYDREX, contains an antimicrobial agent, such as by the composite material being needle punched with an antimicrobial Agion fiber (from Agion Technologies of Massachusetts). Various such antimicrobial agents for treating the fiber are known in the art, a well known one being silver ion, Ag+. Typically, the antimicrobial agent not only helps obviate infection to the wearer, but also helps obviate odor from the wearer. HYDREX, needle punched with an Agion fiber having antimicrobial Ag+ is commercially available from Texel, Inc. of Canada.

(15) Preferably, the absorbent composite 140 includes a barrier film BF, which prevents or retards movement of liquid, for instance out of the garment and onto the wearer's legs. Suitably, the absorbent composite 140 may be impregnated, coated or laminated with the barrier film BF, on a side of the absorbent composite 140 inside the space S defined by the pocket 40. Various materials are known as barrier films BF, and particularly suitable for the barrier film BF is polyurethane, and preferably, it is laminated to the barrier composite 140. The term polyurethane is intended to include copolymers thereof that are suitable, such as polyurethane-polyester copolymer. For instance, a urethane film manufactured by Deerfield Urethane, Inc. is very suitable for lamination to the absorbent composite 140, particularly when the absorbent composite 140 is HYDREX, needle punched with an Agion fiber having antimicrobial Ag+.

(16) Also, an optional barrier film OBF of the same or a different barrier material may be disposed on the outside of the crotch portion 30, such as by lamination.

(17) Although the present invention has been shown and described in detail with regard to only an embodiment of the invention as depicted in the drawings, it should be understood by those skilled in the art that it is not intended to limit the invention to the specific embodiment disclosed. Various modifications, omissions, and additions may be made to the disclosed embodiment without materially departing from the novel teachings and advantages of the invention, particularly in light of the foregoing teachings. Accordingly, it is intended to cover all such modifications, omissions, additions, and equivalents as may be included within the spirit and scope of the invention as defined by the following claims.
