Description
~044851 ., BACKGROUND OF THE INVENTION
The present invention relates to absorbent articles, and more particularly to disposable diapers.
During recent years diapers of the disposable type have come into widespread use. Such diapers are generally constructed having a fluid impervious backing sheet, a fluid pervious top sheet and an absorbent pad located between the top and backing sheets. Although disposable diapers have attained a high degree of popularity with parents since they are discarded after a single use and need not be laundered, proper disposal of the used diapers may pose difficulty for the parent. At certain times, for example during travel in an automobile, immediate disposal of the soiled diapers may not be possible. At other times, for example at an individual's residence, disposal of the diapers may prove trouble-some or unsanitary. It has been suggested that the backing sheet could be removed from tlle soiled diaper, and the remainder of the diaper maybe disposed of in a flush toilet. However, conventional top sheets have sufficient wet strength to prevent their disintegration under use, and the wet strength properties may result in difficulties in sewage disposal systems, for example in septic tank systems, after flushing the d;apers.
Thus, more commonly, the soiled diapers are discarded into trash containers until they may be permanently disposed through other refuse disposal systems.
Although stored only temporarily in a trash container, the unsanitary aspect in this manner of disposal is apparent. Moreover, many parents feel that handling of soiled disposable diapers is objectionable.
A principal feature of the present invention is the provision of a disposable diaper of simplified construction which may be handled and discarded after use in a sanitary and convenient manner.
According to one aspect, the absorbent article of the present invention comprises an absorbent pad assembly having a plurality of marginal edges, and a disposal bag having a cavity and opening means communicating with said cavity, said bag being formed into a compact shape of reduced dimensions and being located and retained while in said compact shape adjacent one of said edges, whereby said bag may be extended to enlarged dimensions after use of the article for placement of the soiled article in the bag and retention therein.
According to another aspect of the invention, a disposable diaper comprises a flexible disposal receptacle having a cavity and opening means opening into the cavity, said receptacle being formed into a configur-ation of reduced dimensions; and an absorbent pad assembly having a front surface, a back surface, a pair of waistline portions, a plurality of longi-tudinally extending folds defining a longitudinally extending central panel ` and panel means having a pair of outermost panels overlying the front sur-face of the central panel, said outermost par,els being laterally movable in at least one waistline portion, and the pad assembly having an end section adjacent an end edge in the one waistline portion, said end section being folded against the front surface of the pad assembly and covering at least

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to Figs. 1 and 2, there is shown a flat diaper designated ~enerally 26 having an absorbent pad assembly 27. The pad assembly 27 has a fluid impervious backing sheet 28 defining a back surface 30 of the pad assembly, a fluid pervious cover or top sheet 32 defining a substantial portion of a front surface 34 of the pad assembly, an absorbent pad 36 positioned intermediate the backing sheet 28 and cover sheet 32, front and back waistline portions 33a and 33b, and a crotch portion 35 ` 15 intermediate the waistline portions 33a and b. The diaper or pad assembly has a pair of side edges 38a and 38b, and a pair of end edges 40a and 40b connecting the side edges 38a and b. The dia-per 26 may also have a pair of conventional tape fasteners 42 adjacent one end edge 40b of the pad assembly, with securing por-tions 43 of the fasteners 42 extending past the side edges 38a and b of the pad assembly for securing the diaper about an infant.
As best shown in Fig. 2, the top and backing sheets 32 and 28, respectively, may extend to the end edges of the diaper.
The flat diaper 26 of Fig. 1 may have a plurality of longitudinally extending folds about fold lines 44a, 44b, 44c, and 44d defining a box-pleat configuration of the diaper, as shown in Fig. 3. As illustrated in Figs. 1 and 3, the box-pleat ~4~
diaper 26 has a longitudinally extending central panel C, a pair of first panels B and D extending from and overlying the central panel C, and a pair of outermost panels A and E extendin~ ~rom and overlying the first panels B and D. The pleat means 46 of the box-pleat diaper may be spaced apart in a lateral central por-tion of the diaper, as shown in Fig. 3, for a purpose which will be described below. As is apparent, the outermost panels A and E
may be moved laterally in the waistline portions 33a and b of the pad assembly to laterally expand the pleat means.
As illustrated in Figs. 2-4, the box-pleat diaper 26 has an end section or flap 48 adjacent the end edge 40a, which may be folded about a lateral old line 50 over the front surface 34 of the diaper, such that the front surface 34 of the end sec-tion or flap means 48 engages against the front surface 34 of the diaper adjacent the end section 48. Preferably, the end edge 52 of the absorbent pad 36 most adjacent the end edge 40a of the dia-per is spaced from the end edge 40a, and the fold line 50 of the end section 48 is located adjacent the end edge 52 of the absorb-ent pad 36, in order that the backing sheet 28 in the end section 48 overlies an end portion of the absorbent pad when the end sec-tion is folded into place on top of the diaper.
As illustrated in Fig. 3, the diaper has a disposal bag or receptacle generally designated 53 located on the front surface 34 of the outermost panels A and E adjacent the fold line 50 in the waistline portion 33a. As shown in Fig. 14, the bag 53 has a pair of flexible side walls 55a and 55b joined together along side edges 57a, 57b, and 57c, and defining a cavity 59 intermedi-ate the side walls 55a and b. The bag 53 has an opening or 104~8Sl olJening means 61 opening into or communicating with the cavity 59 adjacent a longitudinal end 62 of the bag. Longitudinal side sections 63a and 63b of the bag may be laterally folded about longitudinally extending fold lines 65a and 65b against a surface of a central section 67, as shown, to reduce the lateral dimen-sions of the bag. The dimensions of the bag may be further reduced by rolling the laterally folded bag into the configura-tion shown in Fig. 3, although the longitudinal dimensions of the bag may be reduced in any other suitable manner, such as by fold-ing, if desired. Thus, the bag 53 of reduced configuration isplaced on the outermost panels A and E adjacent the fold line 50, and in one embodiment the opening means 61 of the bag may face toward the end edge 40a, as shown.
The diaper also has securing means 54, such ad adhesive, to retain a portion of the front surface 34 of the end section 48 against the underlying front surface 34 of the box-pleat diaper.
Although for convenience the securing means 54 is described in connection with the use of adhesive, it will be understood that other suitable securing means may be utilized to retain the front surface of the end section to the underlying front surface of the diaper, such as by heat sealing. The securing means 54 may com-prise a spot of adhesive 56 intermediate the spaced pleat means 46 on the front surface 34 of the central panel C, and a pair of adhesive lines or spots 58 on the front surface of the outermost panels A and E, such that the bag 53 is located intermediate the : securing means 54 and the fold line 5~. The adhesive spot 56 retains the front surface 34 of the central panel C in the end section 48 against the underlying front surface 34 of the central panel C of the diaper. Similarly, the adhesive lines 58 retain the ~ront surface 34 ol the outermost panels A and E in the end s~ction ~8 against the front surace 34 of the underlying portions ol the oUt~ ost p~ els in the diaper.
After the end section 48 has been folded over the bag <Ind top of the diaper, as indicated by the direction of the arrow in Fig. 4, the end section 48 may be pressed against the underly-in~ portion of the diaper to obtain a good set of the adhesive and retain the end section 48 in place. Thus, as shown in Fig. 5, when the end section 48 is attached to the underlying front sur-face of the diaper, the disposal bag 53 of reduced configuration is capture(l beneath the cnd section 48 by the securing means 54.
~lthough, for convenience, the bag 53 is described as placed in the one waistline portion 33a of the diaper, it is apparent that the bag may be placed in the other waistline portion 33b, if desired.
The use of the disposal bag 53 in conjunction with the folded over end section 48 is described as follows. As shown in Figs. 6 and 7, as the end of the box-pleat diaper 26 adjacent the end section 48 is unfolded during placement of the diaper on an infant, the spots of adhesive 56 and 58 or securing means 54 aintain front surface portions of the end section 48 against the under]ying front surface 34 of the diaper, and retain the bag 53 in place beneath the end section 48. Thus, as the outermost panels A and E are spread outwardly, the outermost panels of the end section 48 are unfolded from under the central panel C of the end section, and the outermost panels of the underlying diaper are unfolded from beneath the bag 53, with the spot of adhesive 56 retaining the bag in place beneath the end section 48, as J
10~
shown in Fig~ 7. When the end of the diaper is completely unfolded, the securing means 54 retains the entire length of the end section 48 in an overlying relationship with a portion of the diaper adjacent the end section 48. In this configuration of the diaper, adhesive spot 56 retains the central panel C of the end section 48 against the underlying portion of the diaper central panel, as well as the bag 53 in place beneath the end section 48, while the adhesive lines 58 retain the outermost panels of the end section 48 against the underlying outermost panels of the pad assembly. As shown, the end section 48 covers the disposal bag 53 to prevent contact of the bag against the skin of the infant during use.
As shown in Fig. 8, after use of the diaper and removal from the infant, the end section 48 may be broken away from the adhesive spot 56 to expose the disposal bag 53. The bag 53 is shown in this drawing as having its opening means 61 facing away from the fold line 50 to demonstrate that the opening means may .
face either way. The bag 53 may be removed from the diaper, after which it may be unrolled and unfolded to its full dimensions. The soiled diaper may then be inserted directly through the opening means 61 into the cavity of the bag, if desired. Alternatively, the user may place his hand in the cavity of the unfolded bag to grasp the soiled diaper through the bag, after which the bag is inverted to cover the soiled diaper, as described below.
In one embodiment of the diaper of the present inven-tion, as illustrated in Fig. 9, a portion of the bag side wall 55b adjacent the opening means 61 is secured to the front surface ~f the pad assembly by the adhesive spot 56 to retain the end of the bag in place on the pad assembly. The bag 53 is shown in the drawing after it has been unrolled and unfolded about the longi-~udinal fold lines 65a and b. In this embodiment of the diaper, the bag has its opening or opening means 61 facing toward the other waistline portion 33b of the diaper. Alternatively, as shown in Fig. 10, the opening means 61 may face away from the other waistline portion 33b of the diaper. Additionally, the bag 53 may be secured to the ~ront surface of the pad assembly by additional securing means 69, such as adhesive spots 71, to firmly anchor the end of the bag adjacent the opening means 61 to the pad assembly, as shown. Securing means 73 is also provided in the cavity 59 of the bag 53 to close the bag after the soiled diaper has been covered by the inverted bag. The securing means 73 may comprise a tape strip 75 having a first portion 77 secured to one of the side walls adjacent the opening means 61, such as side ` 15 wall 55a, and a second securement portion 79 having adhesive ` releasably covered by a release sheet 81.
The use of the bag in the diaper of Fig. 10 to cover `~ the soiled diaper by inverting the bag is described in connection with Figs. 11-13, although it will be understood that any of the diapers previously described may be utilized in a similar manner.
As shown in Fig. 11, the user inserts his hand through the open-ing means 61 into the cavity 59 of the bag 53, which overlies the front surface of the pad assembly, and grasps a lower portion of the soiled diaper through a side wall of the bag, the side wall serving as a protective member for the hand, similar to a glove, eo prevent soiling of the user's hand when contacting the diaper.
Next, the user withdraws his hand from the cavity 59 through the opening means 61 while grasping the diaper through the side wall, 10~8~1 causing ~he bàg 53 to be inverted. In this configuration, the original inner surfaces of the bag side walls are turned outwardly, and the soiled diaE-er has been placed into the cavity S9' of the inverted bag 53, as shown in Fig. 12, with the soiled diaper covered by the bag. Finally, as shown in Fig. 13, the release sheet 81 is removed rom the securement portion 79 of the tape strip 75, and the securement portion 79 of the tape strip 75 may be utilized to close the opening means 61 of the bag, providing a closed cover for the soiled diaper to permit sanitary disposal of the diaper. During inversion of the bag 53 in the diaper of Fig. 9, the bag overlies the back surface of the pad assembly.
Thus, there has been described a diaper having a dis-posal bag for the diaper when soiled. The diaper may be placed in the bag in a convenient and simplified manner without soiling the user's hands. After placement in the bag, the diaper may be discarded in a sanitary manner.
The foregoing detailed description is given for clear-ness of understanding only, and no unnecessary limitations should be understood therefrom, as modifications will be obvious to those ski~led in the art. For example, it is contemplated that the bag 53 may be utilized to cover absorbent articles other than diapers, such as sanitary pads. Additionally, the bag may be located against the back surface of the diaper waistline portion, or may be positioned adjacent side edges of the pad assembly. The bag may be utilized with almost any configuration of a diaper, such as a flat or inverted pleat diaper, as well as a box pleat diaper.
I' will also be apparent that the bag 53 may be secured to the pad assembly by means adjacent the side edge 57b of the bag, such that opening 61 of the bag is located remote the securing means when ~0 the bag is extended to its enlarged dimensions.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to Figs. 1 and 2, there is shown a flat diaper designated ~enerally 26 having an absorbent pad assembly 27. The pad assembly 27 has a fluid impervious backing sheet 28 defining a back surface 30 of the pad assembly, a fluid pervious cover or top sheet 32 defining a substantial portion of a front surface 34 of the pad assembly, an absorbent pad 36 positioned intermediate the backing sheet 28 and cover sheet 32, front and back waistline portions 33a and 33b, and a crotch portion 35 ` 15 intermediate the waistline portions 33a and b. The diaper or pad assembly has a pair of side edges 38a and 38b, and a pair of end edges 40a and 40b connecting the side edges 38a and b. The dia-per 26 may also have a pair of conventional tape fasteners 42 adjacent one end edge 40b of the pad assembly, with securing por-tions 43 of the fasteners 42 extending past the side edges 38a and b of the pad assembly for securing the diaper about an infant.
As best shown in Fig. 2, the top and backing sheets 32 and 28, respectively, may extend to the end edges of the diaper.
The flat diaper 26 of Fig. 1 may have a plurality of longitudinally extending folds about fold lines 44a, 44b, 44c, and 44d defining a box-pleat configuration of the diaper, as shown in Fig. 3. As illustrated in Figs. 1 and 3, the box-pleat ~4~
diaper 26 has a longitudinally extending central panel C, a pair of first panels B and D extending from and overlying the central panel C, and a pair of outermost panels A and E extendin~ ~rom and overlying the first panels B and D. The pleat means 46 of the box-pleat diaper may be spaced apart in a lateral central por-tion of the diaper, as shown in Fig. 3, for a purpose which will be described below. As is apparent, the outermost panels A and E
may be moved laterally in the waistline portions 33a and b of the pad assembly to laterally expand the pleat means.
As illustrated in Figs. 2-4, the box-pleat diaper 26 has an end section or flap 48 adjacent the end edge 40a, which may be folded about a lateral old line 50 over the front surface 34 of the diaper, such that the front surface 34 of the end sec-tion or flap means 48 engages against the front surface 34 of the diaper adjacent the end section 48. Preferably, the end edge 52 of the absorbent pad 36 most adjacent the end edge 40a of the dia-per is spaced from the end edge 40a, and the fold line 50 of the end section 48 is located adjacent the end edge 52 of the absorb-ent pad 36, in order that the backing sheet 28 in the end section 48 overlies an end portion of the absorbent pad when the end sec-tion is folded into place on top of the diaper.
As illustrated in Fig. 3, the diaper has a disposal bag or receptacle generally designated 53 located on the front surface 34 of the outermost panels A and E adjacent the fold line 50 in the waistline portion 33a. As shown in Fig. 14, the bag 53 has a pair of flexible side walls 55a and 55b joined together along side edges 57a, 57b, and 57c, and defining a cavity 59 intermedi-ate the side walls 55a and b. The bag 53 has an opening or 104~8Sl olJening means 61 opening into or communicating with the cavity 59 adjacent a longitudinal end 62 of the bag. Longitudinal side sections 63a and 63b of the bag may be laterally folded about longitudinally extending fold lines 65a and 65b against a surface of a central section 67, as shown, to reduce the lateral dimen-sions of the bag. The dimensions of the bag may be further reduced by rolling the laterally folded bag into the configura-tion shown in Fig. 3, although the longitudinal dimensions of the bag may be reduced in any other suitable manner, such as by fold-ing, if desired. Thus, the bag 53 of reduced configuration isplaced on the outermost panels A and E adjacent the fold line 50, and in one embodiment the opening means 61 of the bag may face toward the end edge 40a, as shown.
The diaper also has securing means 54, such ad adhesive, to retain a portion of the front surface 34 of the end section 48 against the underlying front surface 34 of the box-pleat diaper.
Although for convenience the securing means 54 is described in connection with the use of adhesive, it will be understood that other suitable securing means may be utilized to retain the front surface of the end section to the underlying front surface of the diaper, such as by heat sealing. The securing means 54 may com-prise a spot of adhesive 56 intermediate the spaced pleat means 46 on the front surface 34 of the central panel C, and a pair of adhesive lines or spots 58 on the front surface of the outermost panels A and E, such that the bag 53 is located intermediate the : securing means 54 and the fold line 5~. The adhesive spot 56 retains the front surface 34 of the central panel C in the end section 48 against the underlying front surface 34 of the central panel C of the diaper. Similarly, the adhesive lines 58 retain the ~ront surface 34 ol the outermost panels A and E in the end s~ction ~8 against the front surace 34 of the underlying portions ol the oUt~ ost p~ els in the diaper.
After the end section 48 has been folded over the bag <Ind top of the diaper, as indicated by the direction of the arrow in Fig. 4, the end section 48 may be pressed against the underly-in~ portion of the diaper to obtain a good set of the adhesive and retain the end section 48 in place. Thus, as shown in Fig. 5, when the end section 48 is attached to the underlying front sur-face of the diaper, the disposal bag 53 of reduced configuration is capture(l beneath the cnd section 48 by the securing means 54.
~lthough, for convenience, the bag 53 is described as placed in the one waistline portion 33a of the diaper, it is apparent that the bag may be placed in the other waistline portion 33b, if desired.
The use of the disposal bag 53 in conjunction with the folded over end section 48 is described as follows. As shown in Figs. 6 and 7, as the end of the box-pleat diaper 26 adjacent the end section 48 is unfolded during placement of the diaper on an infant, the spots of adhesive 56 and 58 or securing means 54 aintain front surface portions of the end section 48 against the under]ying front surface 34 of the diaper, and retain the bag 53 in place beneath the end section 48. Thus, as the outermost panels A and E are spread outwardly, the outermost panels of the end section 48 are unfolded from under the central panel C of the end section, and the outermost panels of the underlying diaper are unfolded from beneath the bag 53, with the spot of adhesive 56 retaining the bag in place beneath the end section 48, as J
10~
shown in Fig~ 7. When the end of the diaper is completely unfolded, the securing means 54 retains the entire length of the end section 48 in an overlying relationship with a portion of the diaper adjacent the end section 48. In this configuration of the diaper, adhesive spot 56 retains the central panel C of the end section 48 against the underlying portion of the diaper central panel, as well as the bag 53 in place beneath the end section 48, while the adhesive lines 58 retain the outermost panels of the end section 48 against the underlying outermost panels of the pad assembly. As shown, the end section 48 covers the disposal bag 53 to prevent contact of the bag against the skin of the infant during use.
As shown in Fig. 8, after use of the diaper and removal from the infant, the end section 48 may be broken away from the adhesive spot 56 to expose the disposal bag 53. The bag 53 is shown in this drawing as having its opening means 61 facing away from the fold line 50 to demonstrate that the opening means may .
face either way. The bag 53 may be removed from the diaper, after which it may be unrolled and unfolded to its full dimensions. The soiled diaper may then be inserted directly through the opening means 61 into the cavity of the bag, if desired. Alternatively, the user may place his hand in the cavity of the unfolded bag to grasp the soiled diaper through the bag, after which the bag is inverted to cover the soiled diaper, as described below.
In one embodiment of the diaper of the present inven-tion, as illustrated in Fig. 9, a portion of the bag side wall 55b adjacent the opening means 61 is secured to the front surface ~f the pad assembly by the adhesive spot 56 to retain the end of the bag in place on the pad assembly. The bag 53 is shown in the drawing after it has been unrolled and unfolded about the longi-~udinal fold lines 65a and b. In this embodiment of the diaper, the bag has its opening or opening means 61 facing toward the other waistline portion 33b of the diaper. Alternatively, as shown in Fig. 10, the opening means 61 may face away from the other waistline portion 33b of the diaper. Additionally, the bag 53 may be secured to the ~ront surface of the pad assembly by additional securing means 69, such as adhesive spots 71, to firmly anchor the end of the bag adjacent the opening means 61 to the pad assembly, as shown. Securing means 73 is also provided in the cavity 59 of the bag 53 to close the bag after the soiled diaper has been covered by the inverted bag. The securing means 73 may comprise a tape strip 75 having a first portion 77 secured to one of the side walls adjacent the opening means 61, such as side ` 15 wall 55a, and a second securement portion 79 having adhesive ` releasably covered by a release sheet 81.
The use of the bag in the diaper of Fig. 10 to cover `~ the soiled diaper by inverting the bag is described in connection with Figs. 11-13, although it will be understood that any of the diapers previously described may be utilized in a similar manner.
As shown in Fig. 11, the user inserts his hand through the open-ing means 61 into the cavity 59 of the bag 53, which overlies the front surface of the pad assembly, and grasps a lower portion of the soiled diaper through a side wall of the bag, the side wall serving as a protective member for the hand, similar to a glove, eo prevent soiling of the user's hand when contacting the diaper.
Next, the user withdraws his hand from the cavity 59 through the opening means 61 while grasping the diaper through the side wall, 10~8~1 causing ~he bàg 53 to be inverted. In this configuration, the original inner surfaces of the bag side walls are turned outwardly, and the soiled diaE-er has been placed into the cavity S9' of the inverted bag 53, as shown in Fig. 12, with the soiled diaper covered by the bag. Finally, as shown in Fig. 13, the release sheet 81 is removed rom the securement portion 79 of the tape strip 75, and the securement portion 79 of the tape strip 75 may be utilized to close the opening means 61 of the bag, providing a closed cover for the soiled diaper to permit sanitary disposal of the diaper. During inversion of the bag 53 in the diaper of Fig. 9, the bag overlies the back surface of the pad assembly.
Thus, there has been described a diaper having a dis-posal bag for the diaper when soiled. The diaper may be placed in the bag in a convenient and simplified manner without soiling the user's hands. After placement in the bag, the diaper may be discarded in a sanitary manner.
The foregoing detailed description is given for clear-ness of understanding only, and no unnecessary limitations should be understood therefrom, as modifications will be obvious to those ski~led in the art. For example, it is contemplated that the bag 53 may be utilized to cover absorbent articles other than diapers, such as sanitary pads. Additionally, the bag may be located against the back surface of the diaper waistline portion, or may be positioned adjacent side edges of the pad assembly. The bag may be utilized with almost any configuration of a diaper, such as a flat or inverted pleat diaper, as well as a box pleat diaper.
I' will also be apparent that the bag 53 may be secured to the pad assembly by means adjacent the side edge 57b of the bag, such that opening 61 of the bag is located remote the securing means when ~0 the bag is extended to its enlarged dimensions.
