BACKGROUND OF THE INVE~
The present invention relates to absorbent articles, and ~ore particularlv to disposable diapers.
A various assortment of disposable diapers have been oroposed for use on infants, and have become increasingly po~ular with parents since they may be discarded after a single use and need not be laundered. Such diapers are normally constructed having a fluid impervious backing sheet, a fluid pervious--top-or -cover sheet, and an absorbent pad inte~nediate the backing and -cover sheets.
Many of the diapers have been provided with tape fas-teners which are used to secure the diaper about the infant.
Such fasteners generally take the forrn of a pressure-sPnsitive tape strip having a first end attached to the diaper and a second securement end which is attached-to the diaper during placement.
Prior to use, adhesive on the securement end is covered to pre-vent premature contact of the adhesive against the diaper or other article.
An overriding consideration in construction of the dia-per is the cost of manufacture and the diaper materials, sincethe diaper must be inexpensive to the consumer due to its dis-posability. Accordingly, the backing sheets of such diapers have been made frorn a relatively thin plastic material, such as poly-ethylene, in order to reduce the cost of the backing sheet and the diaper. ~owever, it has been found that when forces are applied to the tape strip during placement and use of the diaper, the tape strips have a tendency to tear the backing sheet and become ruptured from the diaper, thus rendering the diaper rela-~l~23~
tively useless. Additionally, it is desired that the tape fas-tener provides a snug fit and prevents a loose Æit of the diaper about the infant.
SUI~5ARY OF THE INVENTION
A principal feature of the present invention is the provision of a disposable diaper having an improved tape fastener.
The diaper of-the--present-invention comprises, an absorbent pad assembly having opposed-surfaces, a pai~ of side edges, and a pair of end edges connecting the side edges. The diaper has a tape fastener comprising, tape means having a first portion secured to one of the surfaces of the pad assembly, a securement portion for attachment to a spaced portion of the dia-per, an extensible portion connecting the first and securement portions, and elastic means constraining expansion of the exten-sible portion.
A feature of the present invention is that the exten-- sible portion permits enlargement of the tape means responsive to forces applied to the tape strip, thus permitting conformability of the diaper about the infant during use.
Another feature of the invention is that the extensible portion reduces the forces applied to a backing sheet in shear during placement and use of the diaper, and minimizes the possi-bility that the tape means may rupture from the diaper backing sheet.
Stil:L another feature of the invention is that the elas-tic means constrains the extensible portion to provide a snug fit of the diaper about the infant while permitting expansion of the . . . _ . .
- i ~
~23~4 extensible portion.
Yet another feature of the invention is that the extensible portion limits the amount of expansion of the tape means and prevents a loose fitment of the diaper which stherwise might be caused by a completely elastic tape strip.
Further features will become more fully apparent in the following description of the preferred embodiments of this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to Figs. 1 a~d 2, there is shown a dispos-able diaper generally designated 20 having an absorbent pad assem-bly 22. The pad assembly 22 has a fluid impervious backing sheet 24; such as polyethylenë, defining a back surface 26 of the pad assembly, a fluid pervious cover or top sheet 28, such as a non-.
~L~23~S~
woven material, defining a.front surface.30 of..the pad assembly 22, and an absorbent pad 32, s~!ch as.comminuted wood pulp termed in the art as fluff, located intermediate the backing sheet 24 and cover sheet 28. The pad.assembly 22 has.a..pair.of side edges 34, and a pair of end edges 36.connecting.the side.edges 34. The absorbent pad 32 also has a pair of~side~edges.38 and..end edges 40 connecting the.side edges 38. In a preferred.form, as shown, the side edges 38.of the pad.32 are located adjacent the side edges 34 of the pad assembly 22,..and .the fluid .imper.vious backing sheet 24 has lateral side margins..42 folded.o.ver and secured to the top sheet 28,- such that the backing.sheet side margins. 42 cover lat-eral side.margins of the absorbent.pad 32.
The diaper has a pair..of tape.fasteners generally designated-5.0 having.a.pressure-sensitive tape strip 52 and a lS ~ release sheet 54, with each of the fasteners being located adja-cent a side edge 34 of the.pad.assembly.22. The release.sheets 54 have an outer:release..surface 58 and.are attached to the front surface.30 of.the pad assembly 22 adjacent the side edges 34 by~
suitable means, such as adhesive.64. The release sheet S4 may be made.from any suitable material, such as paper or polyethylene, and the outer reiease.surface.58 of the paper release sheet may be formed by a suitable.silicone treatment or coating.
The tape strip 52 has a relatively:inextensible backing 65, such as.paper, adhesive 66 on a front surface.of the backing 65, a first.encl portion 68 secured to the back.surface 26~of the pad assembly.by the adhesive 66 adjacent the.side edge 34, a securement end portion.70 remote the first portion.68.and having.i-its adhesive.66 releasabl.y attached.~to the outer release surface `

~, , , :
58 of the release sheet 54, and an extensible central portion 72 extending between and connecting the first end portion 68 and securement end portion 70. As shown, the central portion 72 of the tape strip 52 has a fold about a laterally extending fold line 74 defining a first section 76 extending between the fold line 74 and first end portion 68 of the tape strip 52, and a sec- -ond section 78 extending between the fold line 74 and the secure-:
ment end portion 70 of the tape strip 52. The first and second _ sections 76 and 78 of the tape strip 52 include adhesive on their front surfaces, and the tape fastener has a sheet 79 of suitable material, such as paper, covering the adhesive on the first and second sections 76 and 78 to prevent attachment between the first ~
and second sections during ùse. As shown, the securement portion 70 of the tape strip 52 may have a folded over end defining a tab 80 to facilitate removal of the tape strip from the release sheet.
The fastener 50 also has an elastic strip 82 extending across the folded extensible portion 72 on the front surface of the tape strip 52, and having opposed ends 84 and 86 attached to the adhesive 66 on the first portion 68 and securement portion 70. The strip 82 may be made of any suitable elastic material, such as an elastic tape, product No. Y482, sold by Minnesota Mining and Manufacturing Company. As shown, the elastic strip 82 may have adhesive 88 on its ends 84 and 86 attached to the adhe-sive 66 and which may extend through a central part 90 of the strip 82.
With reference to Figs. l and 2, the tape fastener 50 is shown in a folded configuration prior to use of the diaper, with the tape strip S2 being releasably attached to the outer release surface 58 of the release sheet 54. In use, the tab 80 3~54 may be grasped in order to peel the securement portion 70 of the tape strip 52 from the release surface 58 of the release sheet 54, as shown in Fig. 3, such that the securement portion 70 of the tape strip 52 extends beyond the side edge 34 of the pad assembly 22. With reference to Figs. 3 and 4, when the secure-ment portion 70 is pulled, the extensible portion 72 unfolds and longitudinally extends while the elastic strip 82 constrains longitudinal expansion of the extensible portion 72. In this manner, the extensible portion 72 permits expansion of the tape fastener during placement and use of the diaper to reduce forces otherwise applied in shear to the diaper backing sheet 24, thus minimizing the possibility that the backing sheet may be torn and tape strip may be ruptured from the diaper. At the same time, the elastic band 82 constrains expansion of the extensible portion 72, and causes a close fit of the diaper about the infant. In addi-_ tion, with reference to Fig. 4, the extensible portion 72 limits the amount of longitudinal expansion of the tape strip 52 and elastic strip 82, and prevents overextension of the tape strip which otherwise might cause a loose fitment of the diaper about the infant.
Another embodiment of the tape fastener is illustrated in Figs.5 and 6, in which like reference numerals designate like parts. In this embodiment, the release sheet 54 is attached to the back surface 26 of the pad assembly 22 adjacent the side edge 34, and the first portion 68 of the tape strip 52 is spaced from the side ledge 34 and located adjacent the release sheet 54.
As before, the elastic strip 82 is connected between the first and securement portions 68 and 70, and the adhesive 66 on the the securement portion 70 is releasably attached to the release surface 58 of the release sh~et: 54. Howeverr if desired, the front surface of the first and second strip sections 76 and 78 may be free of adhesive to prevent attachment during use of the ~astener. Also, the elastic strip 82 is attached directly to the adhesive 66 on the tape strip 52 without additional adhesive on the elastic strip or band 82.
In use, the securement portion 70 of the tape strip 52 is peeled from the release sheet 54, and the securement portion -70 is drawn past the side edge 34 of the pad assembly 22 while the first and second sections 76 and 78 unfold about the fold line 74. When the outer end of the tape strip has been fully extended past the side edge 34, as shown in Fig. 6, the secure-ment portion 70 of the tape strip 52 is located at a position for attaching the tape strip to another portion of the diaper _ during placement on an infant while the elastic strip 82 longi-tudinally constrains the strip 52. In this manner, the tape strip ;2 may be readily removed from the release sheet 54 and extended into a configuration for use in securing the diaper.
Another embodiment of the present invention is illus-trated in Figs. 7-9, in which like reference numerals designate like parts. The fastener of this embodiment is similar to the fastener discussed in connection with Figs. 5 and 6, except that the tape strip 52 is aligned with an edge of the pad assembly 22, such as the end edge 36. Thus, with reference to Fig. 9, after the securement portion 70 has been removed from the release sheet 54, the pad assembly 22 may be gàthered and the tape strip may be utilized to secure tucks 92 in the diaper ~;3'~
between the first portion b8 and the securement portion 70 which is attached to the diaper, resulting in a snug fit of this part of the diaper about an infant.
Another embodiment of the present invention is illus-trated in Fig. 10, in which like reference numerals designatelike parts. In this embodiment, the fastener has a pair of rela-tively short anchoring strips ~4 having adhesive 96 attached between the opposed ends 86 and 84 of the elastic strip 82 and the securement portion 70 and first strip portion 68 in order to enhance the attachment of the elastic strip 82 to the tape strip 52.
Another embodiment of the present invention is illus-- trated in Fig. 11, in which like reference numerals designate like parts. In this embodiment, the fastener 50 has an anchor-ing ~trip 94 having a length greater than the length of the elas-tic strip 82 and having opposed ends 98 attached by adhesive 96 to the adhesive 66 on the tape strip 52. The anchoring strip - 94 has a slit 100 separating end portions of the anchoring strip 94 intermediate the ends 84 and 86 of the elastic strip 82 to permit expansion of the elastic strip 82.
Another embodiment of the present invention is illus-trated in Fig. 12, in which like reference numerals designate like parts. In this embodiment, back surfaces 102 of the strip first and second sections 76 and 78 face each other in the folded extensible portion 72, and the elastic strip 82 is secured to the back surface 102 of the first and securement portions 68 and 70. The extensible portion 72 permits expansion of the tape~
strip 52 while the elastic strip 82 constrains longitudinal l~Z3~
extension of the tape strip 52.
Another embodiment of the present invention is illus-trated in Figs. 13 and 14, in ~7hich like reference numerals designate like parts. In this embodiment, the diaper fastener has a pair of tape strips 52 and 52' on each of the diaper sides, with each of the tape strips 52 and 52' being similar to the fast~ner described in connection with Figs. 1-4. As shown, the tape strip 52' is relatively narrow and the tape strip 52 is located intermediate the second tape strip 52' and the end edge -36 of the pad assembly 22. Also, the securement portions 70 and 70' of both tape strips 52 and 52' may be releasably attached to a common release sheet 54. In use, the securement portions 70 and 70' are peeled from the release sheet 54, and the larger tape strip 52 is utilized to secure the diaper about an infant, as sho~l. in Fig. 14. Next, the second tape strip 52' may be attached to a lower spaced portion of the diaper in order to apply tension to this diaper portion after attachment, and secure - a snug fit of the lower diaper portion about the infant.
Another embodiment of the present invention is illus-trated in Figs. 15-17, in which like reference numerals desig-nate like parts. In this embodiment, the primary tape strip 52 has a first portion 68 attached to the back surface 26 of the pad assembly 22, and the securement portion 70 is releasably attached to a release sheet 54 on the front surface 30 of the pad assembly 22. As shown, the tape strip 52 has a cut~out 104 adjacent the side edge 34 of.the pad assembly, and an auxiliary strip 106 extends through the cut-out 104. The auxiliary strip 104 has an adhesive-bearing securement portion 108 releasably ~3~5'~
attached to a back release surface 110 of the tape strip secure-ment portion 70, and an elastic strip 112 extending between the securement portion 108 and the pad assembly where an end 114 of elastic strip 112 is secured to the diaper beneath the first strip portion 68. In use, the securement portion 70 of the tape strip 52 is utilized to secure the diaper about an infant, as shown in Fig. 17. Next, a tab 116 on the auxiliary strip 106 is utilized to peel the securemènt portion 108 from the tape strip 52, and the securement portion 108 of the auxiliary strip 106 is -attached to a lower spaced portion of the diaper. Thus, theelastic strip 112 of the auxiliary strip 106 causes tension on the lower part of the diaper to obtain a snug fit of this diaper .
part about the infant.
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 skilled in the art.

As shown, the elastic strip 82 may have adhesive 88 on its ends 84 and 86 attached to the adhe-sive 66 and which may extend through a central part 90 of the strip 82.
With reference to Figs. l and 2, the tape fastener 50 is shown in a folded configuration prior to use of the diaper, with the tape strip S2 being releasably attached to the outer release surface 58 of the release sheet 54. In use, the tab 80 3~54 may be grasped in order to peel the securement portion 70 of the tape strip 52 from the release surface 58 of the release sheet 54, as shown in Fig. 3, such that the securement portion 70 of the tape strip 52 extends beyond the side edge 34 of the pad assembly 22. With reference to Figs. 3 and 4, when the secure-ment portion 70 is pulled, the extensible portion 72 unfolds and longitudinally extends while the elastic strip 82 constrains longitudinal expansion of the extensible portion 72. In this manner, the extensible portion 72 permits expansion of the tape fastener during placement and use of the diaper to reduce forces otherwise applied in shear to the diaper backing sheet 24, thus minimizing the possibility that the backing sheet may be torn and tape strip may be ruptured from the diaper. At the same time, the elastic band 82 constrains expansion of the extensible portion 72, and causes a close fit of the diaper about the infant. In addi-_ tion, with reference to Fig. 4, the extensible portion 72 limits the amount of longitudinal expansion of the tape strip 52 and elastic strip 82, and prevents overextension of the tape strip which otherwise might cause a loose fitment of the diaper about the infant.
Another embodiment of the tape fastener is illustrated in Figs.5 and 6, in which like reference numerals designate like parts. In this embodiment, the release sheet 54 is attached to the back surface 26 of the pad assembly 22 adjacent the side edge 34, and the first portion 68 of the tape strip 52 is spaced from the side ledge 34 and located adjacent the release sheet 54.
As before, the elastic strip 82 is connected between the first and securement portions 68 and 70, and the adhesive 66 on the the securement portion 70 is releasably attached to the release surface 58 of the release sh~et: 54. Howeverr if desired, the front surface of the first and second strip sections 76 and 78 may be free of adhesive to prevent attachment during use of the ~astener. Also, the elastic strip 82 is attached directly to the adhesive 66 on the tape strip 52 without additional adhesive on the elastic strip or band 82.
In use, the securement portion 70 of the tape strip 52 is peeled from the release sheet 54, and the securement portion -70 is drawn past the side edge 34 of the pad assembly 22 while the first and second sections 76 and 78 unfold about the fold line 74. When the outer end of the tape strip has been fully extended past the side edge 34, as shown in Fig. 6, the secure-ment portion 70 of the tape strip 52 is located at a position for attaching the tape strip to another portion of the diaper _ during placement on an infant while the elastic strip 82 longi-tudinally constrains the strip 52. In this manner, the tape strip ;2 may be readily removed from the release sheet 54 and extended into a configuration for use in securing the diaper.
Another embodiment of the present invention is illus-trated in Figs. 7-9, in which like reference numerals designate like parts. The fastener of this embodiment is similar to the fastener discussed in connection with Figs. 5 and 6, except that the tape strip 52 is aligned with an edge of the pad assembly 22, such as the end edge 36. Thus, with reference to Fig. 9, after the securement portion 70 has been removed from the release sheet 54, the pad assembly 22 may be gàthered and the tape strip may be utilized to secure tucks 92 in the diaper ~;3'~
between the first portion b8 and the securement portion 70 which is attached to the diaper, resulting in a snug fit of this part of the diaper about an infant.
Another embodiment of the present invention is illus-trated in Fig. 10, in which like reference numerals designatelike parts. In this embodiment, the fastener has a pair of rela-tively short anchoring strips ~4 having adhesive 96 attached between the opposed ends 86 and 84 of the elastic strip 82 and the securement portion 70 and first strip portion 68 in order to enhance the attachment of the elastic strip 82 to the tape strip 52.
Another embodiment of the present invention is illus-- trated in Fig. 11, in which like reference numerals designate like parts. In this embodiment, the fastener 50 has an anchor-ing ~trip 94 having a length greater than the length of the elas-tic strip 82 and having opposed ends 98 attached by adhesive 96 to the adhesive 66 on the tape strip 52. The anchoring strip - 94 has a slit 100 separating end portions of the anchoring strip 94 intermediate the ends 84 and 86 of the elastic strip 82 to permit expansion of the elastic strip 82.
Another embodiment of the present invention is illus-trated in Fig. 12, in which like reference numerals designate like parts. In this embodiment, back surfaces 102 of the strip first and second sections 76 and 78 face each other in the folded extensible portion 72, and the elastic strip 82 is secured to the back surface 102 of the first and securement portions 68 and 70. The extensible portion 72 permits expansion of the tape~
strip 52 while the elastic strip 82 constrains longitudinal l~Z3~
extension of the tape strip 52.
Another embodiment of the present invention is illus-trated in Figs. 13 and 14, in ~7hich like reference numerals designate like parts. In this embodiment, the diaper fastener has a pair of tape strips 52 and 52' on each of the diaper sides, with each of the tape strips 52 and 52' being similar to the fast~ner described in connection with Figs. 1-4. As shown, the tape strip 52' is relatively narrow and the tape strip 52 is located intermediate the second tape strip 52' and the end edge -36 of the pad assembly 22. Also, the securement portions 70 and 70' of both tape strips 52 and 52' may be releasably attached to a common release sheet 54. In use, the securement portions 70 and 70' are peeled from the release sheet 54, and the larger tape strip 52 is utilized to secure the diaper about an infant, as sho~l. in Fig. 14. Next, the second tape strip 52' may be attached to a lower spaced portion of the diaper in order to apply tension to this diaper portion after attachment, and secure - a snug fit of the lower diaper portion about the infant.
Another embodiment of the present invention is illus-trated in Figs. 15-17, in which like reference numerals desig-nate like parts. In this embodiment, the primary tape strip 52 has a first portion 68 attached to the back surface 26 of the pad assembly 22, and the securement portion 70 is releasably attached to a release sheet 54 on the front surface 30 of the pad assembly 22. As shown, the tape strip 52 has a cut~out 104 adjacent the side edge 34 of.the pad assembly, and an auxiliary strip 106 extends through the cut-out 104. The auxiliary strip 104 has an adhesive-bearing securement portion 108 releasably ~3~5'~
attached to a back release surface 110 of the tape strip secure-ment portion 70, and an elastic strip 112 extending between the securement portion 108 and the pad assembly where an end 114 of elastic strip 112 is secured to the diaper beneath the first strip portion 68. In use, the securement portion 70 of the tape strip 52 is utilized to secure the diaper about an infant, as shown in Fig. 17. Next, a tab 116 on the auxiliary strip 106 is utilized to peel the securemènt portion 108 from the tape strip 52, and the securement portion 108 of the auxiliary strip 106 is -attached to a lower spaced portion of the diaper. Thus, theelastic strip 112 of the auxiliary strip 106 causes tension on the lower part of the diaper to obtain a snug fit of this diaper .
part about the infant.
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 skilled in the art.
