The present invention relates to diaper systems and flaps. More specifically, the present invention relates to diaper systems and flaps designed to prevent leakage of bodily fluids.
Diaper systems have long been used with children as a way of containing urine and excrement before a child begins to use a toilet. Diapers contain absorbent material to prevent a wearer from soiling outer garments. Diapers may also be utilized by adults or adolescents who are unable to use a toilet or may be incontinent.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is not intended to identify critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented elsewhere.
In one embodiment, a diaper system has a diaper having a front waist portion for being positioned proximate a wearer's abdominal area when fastened to the wearer and having a front edge, a rear waist portion having a rear edge, a central portion extending from the front waist portion to the rear waist portion, an interior surface, and an outer surface. The diaper system has a flap having an attachment end, a distal end, a midsection between the attachment end and the distal end, an inner surface, and an external surface. The attachment end is coupled to the outer surface. An absorbency area is adjacent the inner surface and has at least one absorbent layer. The midsection has a width that is less than or equal to a width of the distal end.
In another embodiment, a diaper insert has a liquid impermeable external surface, an inner surface, and an absorbency area adjacent the inner surface, the absorbency area having at least one absorbent layer configured to interact with an inner surface of the diaper to form a barrier restricting leakage of bodily fluids. The diaper insert has a distal end, an attachment end, and a midsection between the two. The diaper insert narrows from the attachment end to the midsection. The midsection has a width that is less than or equal to a width of the distal end.
In still another embodiment, an undergarment flap has an external surface, an inner surface adjacent an absorbency area, at least one absorbent layer adjacent the inner surface. The undergarment has an attachment end, a distal end, and a midsection between the attachment end and the distal end. The midsection has opposing sides that are generally mirror images to one another about a vertical line. A width of the midsection is less than or equal to a width of the attachment end and the width of the midsection is less than or equal to a width of the distal end.
In yet another embodiment, a method for minimizing leakage of bodily fluids from exiting a diaper system is provided. A diaper to be worn by a wearer is unfolded. The diaper has a front waist portion for being positioned proximate a wearer's abdominal area, the front waist portion has a front edge. The diaper has a rear waist portion having a rear edge and a central portion extending from the front waist portion to the rear waist portion. The diaper further has an interior surface and an outer surface. Then, a flap is coupled to the outer surface of the diaper. The flap has an attachment end, a distal end, and a midsection between the attachment end and the distal end. The flap further has an inner surface, an external surface, and an absorbency area adjacent the inner surface. The absorbency area has at least one absorbent layer. The flap is then folded up and over into the interior surface of the diaper to form a first fold. The flap is folded again at the midsection to create a folded area and an accordion fold. The flap is folded such that the distal end is proximate the attachment end, and is also proximate the diaper. Lastly, the diaper and the flap are secured to the wearer using side fasteners. The front edge forms a seal with the wearer's abdominal area, and the rear edge forms a seal with the wearer's lower back.
A diaper system 10 having a diaper 100 and a flap 200 may be configured to interact with a wearer to contain bodily fluids. As shown in
The front waist portion 110 may have a front edge 112 defining a top of the front waist portion 114, and opposing sides 116a, 116b that are generally parallel to each other. The rear waist portion 130 has a rear edge 132 defining a top of the rear waist portion 134, and opposing sides 136a, 136b that are generally parallel to each other. The central portion 150 is between the front waist portion 110 and the rear waist portion 130. The front waist portion 110 may be positioned proximate the wearer's abdominal area when the diaper 100 is fastened to the wearer, and the rear waist portion 130 may be positioned proximate the wearer's lower back when the diaper 100 is fastened to the wearer.
Side fasteners 180 may be fixed to the rear waist portion 130 proximate each opposing side 136a, 136b. The side fasteners 180 may be used to attach the rear waist portion 130 to the front waist portion 110. When the side fasteners 180 are engaged, the diaper 100 may be secured to the wearer. The outer surface 170 of the diaper 100 is preferably liquid impermeable. The interior surface 160 may be absorbent, and may consist of at least one absorbent layer 162. The diaper 100 may be disposable, reusable, or constructed from such materials as nonwoven plastic or cotton.
The flap 200 is configured to be coupled to the diaper 100. The flap 200 may be releasably coupled to the diaper 100, or the flap 200 may be securely coupled to the diaper 100. Moreover, the flap 200 may be coupled at a waist band of other types of undergarments, such as training pants, pull-ups, underwear, boxers, or a garter.
As shown in
In the I-shaped embodiments, and as shown in
In some embodiments, a width of the flap 200 is the smallest between opposing sides 260b, 270b of the midsection 230. The width of the flap 200 may vary at different areas of the flap 200. The width of the flap 200 may narrow from the attachment end 210 toward the midsection 230. The width of the flap 200 may similarly narrow from the distal end 220 toward the midsection 230. The width of the flap 200 at the midsection 230 may be less than or equal to a width of the central portion 150 of the diaper 100. In some embodiments, the width of the midsection 230 is less than or equal to the width of the distal end 220. In other embodiments, the width of the midsection 230 is less than or equal to the width of the attachment end 210.
The flap 200 has an external surface 240 and an inner surface 250. The external surface 240 may be liquid impermeable. In some embodiments, for aesthetic purposes, the external surface 240 may have a pattern or other artistic decoration. Further, the external surface 240 may have a wetness indicator. The external surface 240 may have an adhesion area 242 (shown in
The inner surface 250 may be absorbent. In some embodiments, for aesthetic purposes, the inner surface 250 may have a pattern or other artistic decoration. Further, the inner surface 250 may have a wetness indicator. The inner surface 250 may have at least one attachment area 252 proximate the attachment end 210 of the flap 200. The attachment area 252 may be configured to be coupled to the outer surface 170 of the diaper 100. Those skilled in the art will appreciate that the attachment area 252 may utilize an adhesive material, zipper, hook and loop fasteners, safety pins, plastic rivets, roll on glue, or other methods of attachment now known or later discovered. Further, the outer surface 170 of the diaper 100 may be configured to interact with the attachment area 252, and may also utilize an adhesive material, zipper, hook and loop fasteners, or other methods of attachment now known or later discovered. In some embodiments, the attachment area 252 may have a strip of pressure sensitive adhesive material that may be used to couple the flap 200 to the diaper 100. In other embodiments, the attachment area 252 may extend a width of the attachment end 210. In still other embodiments, the flap 200 has multiple attachment areas 252. In some embodiments, the side fasteners 180 may be utilized to secure the flap 200 to the diaper 100. Alternately, the flap 200 may be secured to the outer surface 170 by an adhesive material.
The attachment area 252 may be configured to couple to the outer surface 170 proximate the front waist portion 110. The attachment area 252 may be coupled to the outer surface 170 proximate the front edge 112, and may extend a width of the front edge 112. In other embodiments, the flap 200 may be configured to be coupled to the outer surface 170 of the diaper 100 proximate the rear waist portion 130, and may further be coupled proximate the rear edge 132.
It is foreseeable that the flap 200 may be permanently fixed from the attachment end 210 to the outer surface 170 at the front waist portion 110 of the diaper 100. The diaper 100 and flap 200 may be a single, unitary construction. In those embodiments, the attachment area 252 and the outer surface 170 of the diaper 100 may be indistinguishable and the flap 200 may extend from the front edge 112. In this configuration, when in use, the flap 200 may not extend up and over the top 114 of the diaper 100, but may extend downward towards the central portion 150 of the diaper 100.
The flap 200 may have a planar configuration and a folded configuration (see
At least a portion of the inner surface 250 is adjacent to an absorbency area 280. An area of the absorbency area 280 may be more than half an area of the inner surface 250. In some embodiments, the area of the absorbency area 280 may be generally similar (and in some embodiments, identical) to the entire area of the inner surface 250. In other embodiments, the absorbency area 280 may be adjacent to the inner surface 250 except for a boundary of one half inch or less from an outer perimeter 202 of the flap 200 (see
The absorbency area 280 has at least one absorbent layer 286. The absorbent layer 286 may help to absorb bodily fluids, and may expand and aid in restricting leakage. The absorbent layer 286 is positioned between the attachment end 210 and the distal end 220. The absorbent layer 286 may extend a width of the flap 200. Alternately, the absorbent layer 286 may extend a length of the flap 200. In some embodiments, the absorbent layer 286 extends a width of the distal end 220. The absorbent layer 286 may be configured to expand in an accordion-like fashion.
There may be different numbers of absorbent layers 286 at different parts of the absorbency area 280. In some embodiments, there are additional absorbent layers 286 proximate the distal end 220. In other embodiments, there are additional absorbent layers 286 proximate the midsection 230, and the absorbent layers 286 may be further increased at the folded area 234. The absorbency area 280 may have multiple absorbent layers 286 which may each be composed of a different material. It may be beneficial to have additional absorbent layers 286 at the distal end 220, as well as additional absorbent layers 286 at the midsection 230. Further, there may be additional absorbent layers 286 at a first end 284 of the absorbency area 280. The placement of the absorbent layer 286 may assist in efficiently pushing liquid toward areas that have not yet absorbed liquid. In this regard, the combination of the diaper 100 and the flap 200 may increase the overall efficiency and absorbency when compared to an absorbency of a standard diaper 100. In some embodiments, the absorbent layer 286 may be configured to expand in an accordion-like fashion. Those skilled in the art will appreciate that the absorbent layer 286 may consist of absorbent gel, super absorbent polymers, absorbent fibers, wood pulp, or any other absorbent material now known or later discovered.
In some embodiments, and as shown in
In some embodiments, the flap 200 is reusable. The absorbency area 280 may be configured to be detached and replaced after each use. Alternately, the absorbent layer 286 may be configured to be detached and replaced after each use. Those skilled in the art can appreciate that the absorbency area 280 may be coupled to the flap 200 with an adhesive material, zipper, hook and loop fasteners, or other methods of attachment now known or later discovered. Alternately, the flap 200 may have an insert (not shown) configured to receive the absorbency area 280.
In some embodiments, the flap 200 may be provided by itself, as it may be beneficial for a user to attach the flap 200 to a diaper 100 instead of purchasing diaper systems 10 that have the flap 200 pre-coupled to the diaper 100. A diaper insert and an undergarment flap are substantially similar to the flap 200 as described above, except they are not coupled to the diaper 100.
When in use, the diaper 100 is secured to the wearer. The front edge 112 may be proximate an abdominal area of the user, and the rear edge 132 may be proximate a lower back of the user. The front waist portion 110 may be secured to the wearer such that the front edge 112 may form a seal with the wearer's abdominal area. Likewise, a rear waist portion 130 may be secured to the wearer such that the rear edge 132 may form a seal with the wearer's lower back. When the diaper 100 is secured to the wearer and the wearer shifts positions, it is foreseeable that the changing positions may cause gaps between the wearer and the diaper 100. For example, if the wearer were to place his legs over his head, or sleep on his stomach, this may cause a gap between the front edge 112 and the wearer. The flap 200 may allow the wearer to move more freely while the diaper system 10 maintains leakage protection.
In use, the flap 200 may be attached to the diaper 100 and may be folded at the folded area 234. The folded area 234 may form a barrier between male genitalia of the wearer. The folded area 234 may be positioned below a waist of the wearer. A distal end 220 may be proximate the front edge 112 as shown in
The flap 200 may be used with both male and female users. Male children may more easily urinate towards a front waist portion 110, and the urine may flow over the top 114 and out of the diaper 100. The flap 200 may be positioned to assist in restricting leakage, as is illustrated in
Many different arrangements are possible without departing from the spirit and scope of the present invention. Embodiments of the present invention are described herein with the intent to be illustrative rather than restrictive. Alternative embodiments will become apparent to those skilled in the art that do not depart from its scope. A skilled artisan may develop alternative means of implementing the disclosed improvements without departing from the scope of the present invention. Further, it will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations and are contemplated within the scope of the invention. The description should not be restricted to the specific described embodiments.
