FIELD OF THE INVENTION
This invention relates to a disposable garment made from two half width segments bonded together in the rear panel and not bonded in the front panel for a front opening. The garment is put on by stepping through the leg openings, pulling up, and attaching the front closure tape to define a receptacle for pads of different shape between segments alone, or in combination with cooperating pads located on the inside segment, and other locations to define different embodiments for use as diapers, training pants for children, adult incontinent products, and for feminine hygienic use and undergarments.
BACKGROUND OF THE INVENTION
Present disposable diapers can be applied in a prone position by folding the front portion around the user's crotch and connecting front and rear garment panels with side tapes. Older children can leave one side tape attached, step into the one completed leg opening, pull the diaper up around the other leg, and attach the other side tape to complete the waist and second leg opening, a procedure not easily accomplished by children or adults using oversized diapers for incontinence.
Training pants include larger sizes, higher absorbency pads, side fastening means, and a monolithic absorbent pad enclosed between a pervious upper sustrate and an impervious lower substrate.
There are two general types; garments where side fasteners remain attached and the garment expands around the waist when applied, and, garments with some expandable waist members and side fastening means such as elasticized tapes or hook and loop connecting tapes.
Some training pants have extensible materials for the garment waist so that side fasteners stay connected while the user steps through one leg openings and, balancing on one leg while the second leg is placed through its leg opening, the garment is pulled up over the torso. A typical garment is described in U.S. Pat. No. 6,358,077 B1.
Other training pants are put on by stepping through one of the leg openings, pulled up, and front and rear portions are connected by attaching the other side fastening member as described by U.S. Pat. No. 6,727,404 B2.
The instant garment including well known elements can be applied in a prone position like a diaper or, with sides connected, put on by stepping through both leg openings before attaching the front closure tape to complete the waist opening with the degree of waist snugness found most comfortable by the user. With elastonmeric substrates for the garment structure, elasic side fastening means, and elastic front closure tape, a wide range of waist adjustment is achieved.
The front opening differs from current diapers, training pants and adult care products by allowing frontal inspection of pads, a front opening for male urination, for front opening of the garment to pull down for male or female toilet use, and a thinner appearance and bulk than current adult incontinent products by using one or more thin pads having super absorbent agents for pads selectively shaped and located for the intended use.
The instant garment is preferably made with two bio-degradeable segments and a separable “self contained” leakproof pad with a plastic bottom enclosure for separation and disposal of non-degradeable and bio-degradeable materials. Because absorbent pads are enclosed within liner and the outer cover sheet, current diapers, training pants, and adult incontinent garments are not separable and the entire garment with integral pad is discarded, exascerbating landfill problems.
Some current adult undergarment products have multiple elastic strands aligned transversely and bonded at spaced intervals for expansion and shirred contraction of the waistband. Expanded over the waist, tension is not adjustable and can exert excessive pressure around the waist.
The instant garment avoids the complication of applying multiple elastic strands by providing elastomeric materials and three elastic tapes for adjustment of the waist opening to the degree of preferred tighness and to avoid complex manufacturing manipulations.
In addition to the pad or cooperating pads described below, the front opening permits use of a supplemental front panel pad for insertion between segments for overnight or occasional heavy fluid incontinent use.
The supplemental pad is only used between segments in the front panel area and can be lightly adhered to one of the surfaces between segments for easy removal and replacement without taking the garment off the user.
Five embodiments for combinations of differemt pad shapes and ;pcations are described below in the summary and description of the invention.
SUMMARY OF THE INVENTION
The front opening disposable garment is constructed from two similarly shaped half width overlapped segments selectively bonded between segments in the rear to form a unitary rear panel, and not bonded between segments in the front panel to define a front opening. Segments of all embodiments have elastic strands along side margins to shirr and form leg cuffs when the garment is folded. Substrates used for the segments can be nonwovens and/or paper composites.
Within the context of the two segment assembly, substrates can be extensible, one ply, or a two ply laminate depending on the intended use as disposable diapers, training pants, or for adult and feminine use.
As an assembly of two segments, one of which is reinforced along a linear margin, the garment is used a receptacle for enclosed pads of different shapes, locations, and embodiments of the specifications.
The central overlap area between segments is used for pads of different shapes, and adding a coacting pad inside the garment results in two layer absorbency in the central area.
In current products, extra central absorbency requires thicker machine formed absorbent pads versus the addition of separately processed air laid absorbent pads in two separate layers of the instant front opening garment.
Other shaped pads located between segments include a pad with “wings” on the innermost segment cooperating with a pad with “wings” and attached to the overlapped outermost segment to define a combination full width absorbent pad with “wings” in the front and rear panel areas.
In a first embodiment, a first pad assembly is attached to the inside of the outermost segment in the front panel area. The absorbent pad is enclosed between pervious top and impervious bottom substrates sealed around the pad margins to form a leakproof pad assembly. The pad assembly is a discreet ‘fluid recepticle’ and attached in the front panel area without affecting the front opening.
In a second embodiment, the pad assembly is longitudinally extended an sealed around the periphery. The pad plus end seals are proximate the ends of the garment to provide absorbency in the overlap area of both front and rear panels. The pad assembly is bonded to both segments in the rear panel only, and left unbonded in the front panel area.
In a third embodiment, a pad assembly is extended toward the curvilinear margin and attached to the inside of the outermost segment, forming one half of a garment with full width absorbency. A similar pad assembly on the innermost segment is superposed in mirror-image relationship to the other segment, thus forming the other half of a garment with full width absorbency, including two layer absorbency in the central overlap area.. The front opening remains unbonded and functional.
In a fourth embodiment, pads of the above-embodiment are used in conjunction with a third pad attached to a support panel bonded to the innermost segment at the panel ends and having elastic strands at side margins. When the garment is folded the support panel forms a shirred contoured receptacle for supporting absorbent pads or body parts.
This embodiment results in absorbency of the support panel pad plus double fluid absorbency in the central overlap area and full width fecal absorbency in the two overlapped cooperating pads of embodiment 3.
In embodiment 5, a support panel with stretched elastic strands along side margins and a width substantially equal to the overlap width is attached to the innermost segment near both end margins.
When folded for use, side margins of the support panel shirr to form a contoured receptacle for genetalia and the catheter.
A catheter tube advances through an aperture in the support panel and through an aperture in the central overlap area of the inner segment near the front end margin. The catheter tube advances over an absorbent pad attached to the front panel and passes through a centrally located aperture in the crotch region of the outermost segment. The pad absorbes fluid leakage that passes through the support panel.
These and other objectives will be understood from the detailed description when read in conjunction with other embodiments of the drawings.
