as shown in the exemplary drawings , the present invention is embodied in a bladder insert for use in creating contours and facial expressions in stuffed doll heads while maintaining the softness and pliability of cloth . generally , the stuffed bladder insert comprises a sack or pad filled with a stuffing material that has been stitched prior to filling the bladder to provide the desired shape and contour of the doll head . the stuffed bladder insert is then covered by an outer bladder or “ skin ” of fabric to complete the doll head . optionally , additional smaller stuffed bladders or pads are attached to the stuffed bladder insert to provide additional contouring prior to adding the fabric skin of the outer bladder . as will be appreciated , the bladder insert substantially fills the doll head . thus , no additional stuffing is required after the bladder insert is inserted into the outer bladder to complete the doll head . the bladder insert is made of a stretch cloth or other knit or elastic fabric . examples of suitable fabrics include , but are not limited to , lycra ®, spandex , knit jersey , gaberdine , rib stitch or interlock stitch cotton , wool , polyester , nylon , acrylic , blends thereof , or the like . preferably , the bladder insert is made from a knit jersey fabric . as shown in fig1 three parts are used to construct the bladder insert : an upper part 10 , a lower part 12 , and a back part 14 . the upper and lower parts preferably include stitched darts , or tapered folds , which create different shapes and contours of the doll head . stitched darts are well known in the cloth and garment business , and are generally formed by folding a piece of fabric and sewing a line of stitches extending from the fold - line to the edge of the fabric . typically , the line of stitches is formed at a diagonal to the fold , creating the tapered fold or dart , with the size of the dart depending on the angle of the line of stitches relative to the fold - line . as will be appreciated , the larger the angle of the line of stitches relative to the fold - line , the larger the dart and the greater the shaping or contouring effect of the dart . it should be noted that the present invention contemplates shapes or contours formed in the bladder insert by sets of contouring stitches other than in the form of darts . for example , a line of stitches parallel to a fold or sewn in a curve relative to the fold may be used to form distinctive shapes or contours . in the embodiment shown in fig1 the upper part 10 of the bladder insert includes four darts , 16 , 18 , 20 , and 22 . darts 16 , 18 , and 20 produce a rounded contour in the bladder insert that defines the forehead in the doll head . dart 22 produces a contour that defines the bridge of the nose and the area between the eyes of the doll head . darts 16 , 18 , 20 , and 22 are all sewn in the upper part 10 such that the tapered folds of the darts are on one side of the upper part . the side of the upper part with the tapered folds is the inner surface , while the opposite side is the outer surface . in fig1 the outer surface 38 of the upper part is shown . similarly , the lower part 12 of the bladder insert includes seven darts , 24 , 26 , 28 , 30 , 32 , 34 , and 36 . darts 24 , 26 , 28 , 30 and 32 produce a rounded contour in the bladder insert that defines the shape of the jaw in the doll head , while darts 34 and 36 define the shape of the chin . darts 24 , 26 , 28 , 30 , 32 , 34 , and 36 are all sewn in the lower part 12 such that the tapered folds of the darts are on one side of the lower part . the side of the lower part with the tapered folds is the inner surface , while the opposite side is the outer surface . in fig1 the outer surface 40 of the lower part is shown . as will be appreciated , the position , length and number of contouring stitches , in the form of darts or otherwise , used in the upper and lower parts will determine the shape and contour of the bladder insert . fig1 shows an arrangement of darts suitable for producing a bladder insert that will simulate a human face when incorporated into a doll head . however , other arrangements of stitches and / or darts are also contemplated and can be used to produce bladder inserts that will simulate a wide variety of faces , including faces of other species , such as bears , cats , dogs and the like , for use in other stuffed toys . after adding the desired stitches or darts to the upper and lower parts , the bladder insert is assembled by sewing the three pieces of the bladder insert together . first , the upper and lower parts are placed together with outer surfaces 38 and 40 facing each other and edges 42 and 44 aligned . a line of stitches , or seam , 46 , sewn through the two parts 10 and 12 and along aligned edges 42 and 44 , joins the two parts 10 and 12 to form a front part . next , the joined upper and lower parts are unfolded along seam 46 , and are placed together with the back part 14 , with the outer surfaces 38 and 40 facing outer surface 48 of the back part . the back part , which typically is the same size or slightly smaller than the joined upper and lower parts , is centered on the joined upper and lower parts with the top 50 and the bottom 52 of the back part positioned at or near the top 54 of the upper part and the bottom 56 of the lower part , respectively . the back part 14 is joined to the upper and lower parts by a seam 58 , sewn around the back part near its edge , leaving a gap 60 . the assembled bladder insert is then turned inside out through gap 60 , such that all darts , seams and other stitches are located inside the bladder insert and the outer surfaces 38 , 40 and 48 are all located on the outside of the bladder insert . a front view of the assembled bladder insert is shown in fig2 and a back view is shown in fig3 . also shown in fig3 are four marks , 62 , 64 , 66 , and 68 . optionally , marks 62 and 64 are placed on the outer surface 48 of the back part 14 of the bladder insert so as to be positioned in the back of the doll head directly opposite the left eye socket of the doll head . similarly , marks 66 and 68 are placed on the back part of the bladder insert so as to be positioned in the back of the doll head directly opposite the right eye socket . these marks may be applied to the back part of the bladder insert before or after the back part is attached to the upper and lower parts . the bladder insert is stuffed to fill out the contours created in the bladder insert by the placement of darts and other stitches , to thereby provide the desired final shape of the doll head . materials suitable for stuffing the bladder insert include cotton , wool , kapok , polyester fiber or foam , or other fibrous or spongy material . after the bladder insert is stuffed to substantially provide the desired shape of the doll head , the gap 60 in the bladder insert is sewn shut . optionally , additional smaller stuffed bladders or pads may be attached to the stuffed bladder insert to provide additional contours and shapes . for example , fig4 shows two views , front and side , of a small nose bladder 70 that is used to create a more pronounced nose on the doll head . the nose bladder 70 consists of a small piece of fabric 72 that is filled with stuffing then sewn shut with stitches 74 to enclose and secure the stuffing . the fabric and stuffing used to produce the nose may be the same as that used to produce the bladder insert . in the embodiment shown in fig4 a small round nose bladder is formed from a circular piece of fabric filled with stuffing to produce a small ball . as will be appreciated , a wide variety of other shapes may be formed by varying the shape and size of the fabric piece , the amount of stuffing , and the placement of stitching used to enclose the stuffing . [ 0045 ] fig5 shows a left side view of a stuffed bladder insert 76 . also shown in fig5 is the placement of a small nose bladder on the stuffed bladder insert . the nose bladder 70 is placed against the stuffed bladder insert 76 at the desired attachment point , and is secured to the bladder by a series of stitches . [ 0046 ] fig6 shows a front view of a stuffed bladder insert 76 . as shown in fig6 darts 16 , 18 , and 20 produce a rounded contour to form the forehead of the doll head . likewise , darts 24 , 26 , 28 , 30 and 32 produce a rounded contour to form the jaw of the doll head . in this embodiment , a small nose bladder 70 is attached to the stuffed bladder insert 76 just below the dart 22 forming the bridge of the nose . [ 0047 ] fig7 shows a left side view of a stuffed bladder insert 76 after stitches have been added to create eye sockets . to create the left eye socket , a needle and thread is inserted into the back part 14 of the bladder insert 76 at mark 62 and is pulled through the front of the bladder insert at a point 78 located near the desired location of the left eye , leaving a portion of the thread trailing from insertion point 62 . the needle and thread is then inserted back into the bladder insert at a point 80 , located near point 78 , and drawn through the bladder insert , exiting the bladder at mark 64 . the thread is then pulled back and secured , typically by tying it off with the thread trailing from insertion point 62 , thereby pulling a portion of the bladder insert between points 78 and 80 back toward the back part 14 , creating the left eye socket . the right eye socket is made in the same way , using marks 66 and 68 , shown in fig3 . the shape and contour of the eye sockets can be varied , depending on the depth and position of the stitches used to catch and secure the front of the bladder insert to the back part . the stuffed bladder insert shown in fig7 is substantially in the form of the doll head , with contours defining the shape of the forehead , nose bridge , chin , jaw and eye sockets , and , optionally , a nose bladder defining the shape of the nose . in order to give the doll head a more life - like appearance , and to conceal the stitching and / or additional bladders used to create the shape of the head , an outer bladder with a fabric “ skin ” is used to cover the stuffed bladder insert . the outer bladder is generally formed by sewing two or more pieces of fabric together to form the bladder in a size and shape suitable for containing the stuffed bladder insert . darts or other stitches may be used to give the outer bladder a suitable rounded shape . fabrics suitable for use in forming the fabric skin of the outer bladder include lycra ®, spandex , knit jersey , gaberdine , rib stitch or interlock stitch cotton , wool , polyester , nylon , acrylic , blends thereof , or the like . preferably , the outer bladder is made from a flesh - colored knit jersey fabric . other fabric colors may be used depending on the desired final appearance of the doll head . similarly , the outer bladder may be formed in shapes other than rounded , depending on the shape of the stuffed bladder insert and the desired final appearance of the doll head . [ 0050 ] fig8 shows a front view of a die cut front piece 82 of the outer bladder . although this embodiment is shown with simulated hair 84 attached to the outer bladder 86 , the addition of “ hair ” is optional . yarn is preferably used to simulate hair , although other materials , including strands of cotton or wool fabric , synthetic fibers , and the like may be used . preferably , the simulated hair is sewn to the outer bladder , but may also be attached by glue or other adhesive . if desired , facial features such as a mouth , eyebrows and eyes , may be printed , painted , embroidered , heat transferred or otherwise applied to the fabric skin on the front piece of the outer bladder . [ 0051 ] fig9 shows a back view of a die cut back piece 88 of the outer bladder . as with the front piece of the outer bladder , simulated hair 84 may be sewn or glued onto the back piece 88 . an opening 90 extends down the middle of the back piece 88 from a point near the top 92 of the back piece to the open neck hole 94 . [ 0052 ] fig1 shows a pair of ears 96 , which may optionally be attached to the doll head . each ear is formed from two substantially circular pieces of fabric 98 , which are placed on top of each other and sewn together with a line of stitches 100 placed around the edge of the circular piece , leaving a gap 102 in the stitching . the ear is turned inside out , thereby concealing the seam formed from the stitching 100 inside the ear . as will be appreciated , the shape of the ears may be varied by changing the size and shape of the pieces of fabric used to make the ears . in addition , the ears may be filled with a stuffing . the outer bladder is assembled by placing the front piece 82 and the back piece 88 together with the outer surfaces together , and sewing the two pieces together along the outer edges , leaving the opening 90 and the neck hole 94 open . the outer bladder is then turned inside out to conceal the seam within the outer bladder . a front view of an assembled outer bladder 104 is shown in fig1 , with ears 96 sewn onto the outer bladder at either side . [ 0054 ] fig1 shows a headless stuffed doll body 106 . the outer bladder 104 is placed on the doll body 106 , and sewn to the doll body along the neck hole 94 as shown in fig1 . the assembled doll 108 is shown in fig1 , before the bladder insert is inserted . to provide the shape and facial contour of the doll head in the assembled doll 108 , the stuffed bladder insert 76 is inserted into the outer bladder 104 through the opening 90 , as shown in fig1 . as will be appreciated , because the bladder insert is already shaped according to the desired contour and shape of the doll head , and further because the bladder insert substantially fills the outer bladder , the insertion step is very simple and straightforward , with little or no need to manipulate the bladder insert , or portions thereof , within the confines of the outer bladder after insertion . after insertion , the opening 90 in the back of the outer bladder 104 is sewn shut , to thereby secure the bladder insert within the outer bladder . a back view of the finished doll 110 , with is shown in fig1 . a side and a front view of the finished doll 110 is shown in fig1 . in the side view , the bladder insert 76 is shown with dashed lines inside the outer bladder 104 of the doll head . both views show the shape and facial contours produced by the bladder insert , including the nose 112 , forehead 114 , jaw 116 , and chin 118 . it should be appreciated that these previously illustrated embodiments are only exemplary and therefore other embodiments are not excluded . it should be appreciated that the bladder insert can be constructed from fewer or more than three pieces of fabric . it should be further appreciated that the placement of darts and other stitches shown in the drawings are exemplary , and that one of ordinary skill in the art will appreciate that the placement of such stitches can be modified to produce different shapes and contours of the stuffed head . it should be further appreciated that additional small stuffed bladders may be optionally added to the bladder insert before it is inserted into the outer bladder to thereby produce additional shapes and contours . as shown in the drawings , a small stuffed bladder may be used to produce a nose in the stuffed doll head . similarly , small stuffed bladders of various shapes can be attached to the bladder insert to emphasize the chin , cheeks , forehead , lips and the like . although the invention has been described in detail with reference to only a few preferred embodiments , those having ordinary skill in the art will appreciate that various modifications can be made without departing from the spirit of the invention . for example , it should be understood that the bladder insert of the present invention can be modified to produce a wide range of shapes and contours to thereby produce a variety of soft doll heads , including heads suitable for use with stuffed animals and the like . with such possibilities in mind , the invention is defined with reference to the following claims .
