This invention relates generally to the field of pillows. In particular, the invention relates to nursing and feeding pillows. In some embodiments, such pillows axe provided with various attachments to facilitate positioning of a baby on the pillow.
Over the years, a variety of support pillows have found commercial acceptance. One exemplary support pillow is the Boppy® pillow, marketed by The Boppy Company. Various forms of this pillow are described in U.S. Pat. Nos. 5,261,134, 5,546,620, 5,661,861, and 6,055,657, among others. The complete disclosures of these patents are incorporated herein by reference.
One particular use of support pillows is to facilitate feeding and nursing. This invention relates to ways to enhance the use of various embodiments of nursing and feeding pillows.
In one embodiment, the application describes a feeding pillow having a pillow body that is generally defined by a medial region and two opposing arms that extend from the medial region. The medial region is configured to be placed near or adjacent a user's stomach, with the arms generally near or adjacent the user's sides. Also, the pillow body has a top surface that is adapted to support a baby and a bottom surface that is adapted to be placed on the user's lap, although it will be appreciated that the pillow could be flipped over and used in the opposite manner. The pillow body comprises a fabric cover and a fill material disposed within the fabric cover. A support member is removably coupled to the pillow body at or above the top (or bottom) surface.
In one aspect, the support member has a firmness that is different than a firmness of the pillow body. For example, the support member may have a firmness that is greater than that of the pillow body. Such a relatively firm support member may be particularly useful in orienting a baby when positioned on the pillow, such as when a mother is nursing the baby. However, in some cases, the firmness of the support member could be less than that of the pillow body.
In another aspect, the support member covers a majority of the medial region at the top surface. This configuration is particularly useful when a baby is laid atop the pillow. In some cases, the support member may cover substantially all of the medial region at the top surface.
For convenience of description, the support member may be defined in terms of a top surface, a bottom surface, a distal side and a proximal side. In one aspect, the top surface generally angles downward from the distal side to the proximal side. This helps to position the baby against the mother, and is particularly useful when nursing the baby.
The pillow body may include a pocket at the top surface. The pocket defines an enclosure into which the support member is removably received. In this way, the support member may be removed simply by slipping it out of the pocket. In one aspect, the pocket is sewn about an outer periphery of the pillow body. The pocket may also define an opening, and a zipper may be used to close the opening. This opening may be located at or near the outer periphery, the inner periphery (adjacent the well region), along one of the arms, across the top of the pillow, and the like.
In one particular configuration, the medial region of the pillow body has a length in the range from about 14 inches to about 26 inches and a width in the range from about 6 inches to about 16 inches. Each of the arms may have a length in the range from about 6 inches to about 20 inches, and a width in the range from about 4 inches to about 8 inches to define a stomach receiving region with a width of about 7 inches to about 18 inches. Also, the support member may have a length in the range from about 15 inches to about 25 inches, a width in the range from about 5 inches to about 15 inches, a height at the distal side in the range from about 2 inches to about 5 inches, and a height at the proximal side in the range from about 0.25 inches to about 2 inches to define an angle of inclination in the range from about 20 degrees to about 35 degrees.
In one particular arrangement, the support member may further comprise reduced sized arms or rounded projections that are shorter than the arras of the pillow body. The support member may also include a contoured upper surface so as to define an elevated distal edge and a recessed center region. The support member may be constructed of a variety of materials to provide the appropriate firmness, including materials such as an open cell foam, a closed cell foam, a gel material, visco-elastic materials, inflatable bladders, and the like.
Optionally, a belt may be removably attached to the arms. For example, a pair of buckle clips may be used to removably attach the belt to the pillow body.
In another embodiment, the invention provides an exemplary method for supporting an object on the lap of a sitting user. According to the method, a support pillow is placed on a user's lap. The support pillow comprises a pillow body generally defined by a medial region and two opposing arms that extend from the medial region, and the medial region is placed near or adjacent the user's stomach, with the arms generally near or adjacent the user's sides. The pillow body also has a top surface and a bottom surface that is placed on the user's lap. The pillow body comprises a fabric cover and a fill material disposed within the fabric cover, and the support pillow further comprises a support member removably coupled to the pillow body at or above the top surface. With this arrangement, an object is placed onto the support pillow so as to rest on the support member.
In one aspect of the method, the support member has a firmness that is greater than a firmness of the pillow body, and the support member has a top surface, a bottom surface, a distal side and a proximal side. Also, the top surface of the support member generally angles downward from the distal side to the proximal side. Further, the object is a baby who, when placed on the pillow, angles toward the user's chest when resting on the support surface. In this way, the mother may more easily nurse the baby. If needed, the pillow may be secured about the user's waist using a belt.
In a further aspect, the support pillow further comprises a pocket at the top surface of the pillow body. The pocket defines an enclosure into which the support member is removably received. This allows the support member to be removed from the pocket. Such a configuration permits the support member to be replaced with a different support member, such as one with a different geometry and/or firmness. This also provides the benefit of allowing the pillow to be washed in washing machine after removing the support member.
In another embodiment, the invention provides a feeding pillow that is constructed of a pillow body that is generally defined by a medial region and two opposing arms. The medial region is configured to be placed near or adjacent a user's stomach, with the arms generally near or adjacent the user's sides. The pillow body has a top surface that is adapted to hold a baby and a bottom surface that is adapted to be placed on the user's lap. The pillow body further includes a fabric cover and a fill material disposed within the fabric cover. Also, a support member is positioned at or near the top surface or the bottom surface such that one of the surfaces is more firm than the other surface. In this way, a user has the option of choosing which surface to hold the baby and which surface to place on the user's lap. As one specific example, a mother may choose to have a more firm surface for holding a baby while the bottom surface, that rests on the user's lap, is more plush and pliable. However, it will be appreciated that depending on the size and body shape of the user, or the size and body shape of the baby, the user may prefer to have the firmer side up or to have the softer side up.
In one aspect, the support member comprises a layer of dense foam material. In some cases, the foam layer may be sewn or otherwise connected to the fabric cover. In one option, the foam layer includes a depression such that the top surface includes a recessed region that is adapted to hold a baby.
The invention provides various pillows that may be used in a variety of ways, usually in association with the care of a baby. Merely by way of example, the pillows of the invention may be used to assist with nursing or feeding a baby. In a typical use, the pillow will be placed on a user's lap, with the baby resting on a top surface of the pillow.
In one particular arrangement, the pillows may be constructed of a medial region and two side arms that are widely spaced-apart from each other so that the pillow may be placed about the waist and/or stomach of an adult. In some cases, the arms may be somewhat flexible to permit the arras to be further separated or distanced from each other. The arms may be somewhat resilient so that if spread and released, they spring back to their original position. This permits the pillow to be placed about large objects, with the arms tensioned against the object, yet not uncomfortably. For example, when the ends of the pillow arms are separated enough to be placed about the torso of an average sized adult, the inward force produced by each arm is sufficient to hold the pillow in place about the torso, yet not so tight that it is uncomfortable. Further, when the pillow clings about a relatively large object, the medial region does not buckle, but keeps its shape. When removed, the pillow's resilience permits it to spring back to its original shape. In some cases, the arms may be sufficiently separated in their normal position such that they can be easily placed about a user's waist without the need to separate the arms. Such an arrangement is particularly useful when the pillow is placed on a user's lap and a baby is positioned on top of the pillow. Optionally, a belt that is coupled to the arms may be used to hold the pillow in place.
In one important aspect, the pillow has a top surface and a bottom surface. The top surface is used to support a baby while being held by the mother, caregiver, or the like, while the bottom surface is designed to rest on the user's lap. The bottom surface may be constructed to be somewhat firm, yet can have some “give” when resting on a user's lap. As such, the top surface may be more firm than the bottom surface. This helps to ensure that the user will feel comfortable when the pillow is resting on her lap. However, it will be appreciated that the softer surface could also be used to hold the baby while the firmer surface rests on the user's legs. This may depend on a variety of factors, including the mother's preference, the size and body shape of the mother or the baby, and the like.
As previously mentioned, the top surface which holds the baby may be configured in some embodiments to be more firm than the lower surface. This provides increased support to the baby. Also, the top surface may be configured as a removable insert or support surface. This permits a pillow with a uniform firmness to have a firmer surface by utilizing the more firm insert or support surface.
To construct the pillow, a cover or shell is used to surround a fill material. In one embodiment, the fill material may completely fill the interior except near the top surface of the pillow where a layer of dense foam may be provided to increase the stiffness and rigidity of the pillow at the top surface. In some cases, such as where a firm insert or removable support member is used, the entire pillow body may be filled with the fill material, with the added firmness being provided by the insert. Examples of foam materials that may be used to provide the increased firmness at the top surface include polyurethane foams, neoprene, latex, memory foams and the like. The fill material used to make the pillow may be such that the pillow is relatively firm when filled, particularly so that the pillow will not significantly deflect under the weight of a baby. Examples of materials that may be used include polyester fibers, foamed materials, and the like. One method for filling the cover with a fill material is described in U.S. Pat. No. 7,089,639, which is incorporated herein by reference.
The cover may be constructed of a top and bottom main portion using one or more pieces of fabric and a center and/or side panel(s) at the inner periphery and/or sides of the pillow. In some cases, the overall shape of the pillow may be similar to those described in U.S. Pat. Nos. 5,261,134, 5,661,861, 5,546,620 and 6,055,687; 6,685,024; 6,434,770; 6,671,908; 7,017,212; 6,279,185; 6,412,128; 7,451,508; 7,127,760; 6,944,898; 7,587,773; 7,472,443; 7,404,222; 7,430,774; 7,832,036; 7,778,752; 6,038,720; 6,763,539; and U.S. patent application Ser. No. 13/071,358, filed Mar. 24, 2001 and entitled “Travel Nursing Pillow,” incorporated herein by reference. One particularly useful geometry is a U-shape with a medial region and shortened arms. The medial region is sized to extend across the user's stomach and be gently curved. The arms are spaced apart so as to extend along the user's sides without buckling of the pillow. The medial region is also wide enough to hold a baby while feeding. The main portion of the cover or shell may, in some cases, be constructed of two or more pieces of material which are sewn to each other, with the center and/or side panel(s) being sewn to the main portion, although other coupling techniques may be used, such as by using a fabric glue. Some techniques for attaching a center panel of material to a cover are also described in U.S. Pat. No. 6,412,128 and U.S. Patent Publication No. 2008/0010750, which are incorporated herein by reference. The material used to construct the main portion(s) of the cover and/or the center and/or side panel(s) may be a fabric, such as cotton, polyester, velvet, cotton/poly blends and the like. Such fabrics permit the pillow to be firmly stuffed with fill materials. When stuffed in this manner, the pillows are able to maintain their shape for extended time periods. Such fabrics also provide an aesthetically pleasing surface.
The support pillows of the invention may find use with a variety of applications where the arms are placed around or adjacent an object. Merely by way of example, such applications may include placement about a torso to facilitate nursing or feeding or an infant, the holding of an object, such as a book, a toy, food, or the like.
The stiffening layer or member used at or near the top surface may conveniently be sewn or otherwise attached to the cover at the top surface. In some cases, a separate stiffening member could be attached to the pillow body in a manner similar to a “pillow top” mattress. Further, in some cases, a stiffening member could be removably attached to the top surface similar to a “topper” used on mattresses.
In one embodiment, increased firmness at the top surface may be obtained by using a separate support member having a firmness that is greater than the resilient fill material that is used to construct the pillow body. The support member may be configured to be removably attached to the pillow body. Making the support member removable from the pillow body provides a number of advantages including: the ability to remove the support member when washing the pillow (such as in a conventional washing machine), replacing the support member with one of a different size, shape and/or firmness, the ability to use the pillow without the firmer surface, and the like.
The support member may be removably attached to the pillow body in a variety of ways. For example, the pillow body may include a pocket into which the support member is inserted. The pocket may be an integral part of the cover or a separately attached pocket or sleeve. A variety of fasteners could be used to close the pocket or sleeve, such as a zipper, buttons, snaps, clips, ties, a hook and loop fastener material, and the like. As another example, the support member could be attached using discrete fasteners, such as by a hook and loop fastener material, snaps, buttons, clips, a zipper, ties, buckles and the like. Further, in some cases, the support member may be positioned atop the pillow without using any fasteners.
Another way to removably attach the support member to the pillow body is by using a separate slipcover that slips over the pillow body. The support member may be integrally attached to the slipcover or removably attached, such as within a sleeve or pocket of the slipcover. The slipcover could fully envelop the pillow body, or could slip over only a portion, such as the top surface in a manner similar to a mattress cover.
One particular advantage of using a separate support member is that it may be engineered to have a size, shape and/or firmness that is different from the rest of the pillow. This may be accomplished by using materials that can be shaped and/or contoured more easily than using a traditional fiber fill material. Examples of materials that can be used for the purpose include open cell foams, closed cell foams, visco-elastic materials, gels, inflatable bladders and the like. The support member can be made using a molding process or a self-skinning foam process.
The removable support member may have an outer shape that is somewhat similar to the top surface of the pillow body. In some cases, the support member could be slightly smaller, especially along the arms (or may include no arms at all). This reduced size helps when inserting the support member into a pocket.
The support member may also be inclined from a distal side (away from the user) to a proximal side (adjacent the user). In other words, a top surface of the support member may angle downward toward the user. This positions the baby somewhat on her side when laying lengthwise across the pillow, thus helping to position the baby's mouth near the mother's breast when nursing and keep the baby from rolling away from the mother. The angle of decline may be in the range of about 20 degrees to about 35 degrees off horizontal. While defined in terms of an “angle”, it will be appreciated that the top surface of the support member may not be flat or planar and the “angle” has reference to the height at the distal side relative to the proximal side.
For example, in some cases one or more of the surfaces of the support member could be shaped or contoured. For instance, the top surface could be recessed relative to an outer edge to form a lip around at least a portion of the support member. This lip helps to hold the baby on the pillow and also assists in positioning the baby relative to the mother. Other shapes are also possible, such as a flat inclined surface. Further, the bottom surface could also be contoured so as to provide a friction surface to help secure the support member to the pillow body.
The firmness of the support, member may be defined relative to the pillow body, such as 2 or 3 times as firm, or in terms of a specific firmness or density. Also, in some cases, the support member itself could have layers/sections with different firmnesses and/or constructed of different materials. Further, the support member could be constructed of multiple components and/or layers. For example, the support member could be constructed of a relatively firm base layer and a top layer of a less firm material or vice versa. Or, the center portion could be less firm while the ends are more firm. Also, different support members may be included in a kit or sold separately so that the top surface of the pillow can be customized by the user. This allows the pillow to be used in a wide variety of applications. For example, different support members could be used for different sized babies, different sized mothers or other users. Also, such support members could be used to configure the pillow to be used for bottle feeding, simply holding the baby, or for non-baby uses, such as holding a book or other object.

Feeding pillow 10 includes a somewhat curved outer surface or periphery 12 which is rounded. Pillow 10 further includes a somewhat curved central inner surface or periphery 14 which defines a well region 16. While the body of the pillow 10 is substantially continuous and uniform, with curved surfaces 12 and 14 also being continuous, it is convenient to consider the pillow body as having a medial region 15 and two arms 18 and 20. The arms 18 and 20 extend somewhat perpendicularly away from the medial region 15, but are slightly curved out from the outer periphery to give the pillow 10 its overall curved configuration. While the continuous structure does not provide a precise or exact division between the medial region 15 and each arm, considering the body of the pillow in view of these components facilitates a description of the structure and function of the pillow 10.
Arms 18 and 20 include respective ends 22 and 24, positioned remotely of the medial region 15. Pillow 10 is proportioned so that ends 22 and 24 can easily fit around the sides of an adult's torso or waist. Pillow 10 has a bilateral symmetry with respect to a central plane which passes vertically through medial region 15. Pillow 10 is also symmetrical about a mid-plane which horizontally bisects the pillow body. In some cases, it may be convenient to refer to a center line which horizontally lies along and bisects the pillow. Further, pillow 10 includes a top surface 21 and a bottom surface 23, with top surface 21 designed to support a baby while bottom surface 23 is designed to rest on a user's lap. As described herein, top surface 21 could in some cases be placed face down on the user's lap while bottom surface 23 is placed faced up and used to hold the baby.
Well region 16 has a width that is selected to permit the support pillow to reach around the torso or waist of most users. The pillow 10 is also constructed so that the arms 18 and 20 may be moved away from each other to vary the width so that the pillow 10 may be used in a variety of applications, including larger sized adults.
Pillow 10 includes a central core which may be constructed of a fill material 37 such as a hypoallergenic polyester filling. The central core is encased by a cover 34. The majority of cover 34 is constructed of a material that is compliant while generally not stretchable. Examples of such fabrics include cotton, polyesters, cotton/poly blends, or other pliant conforming fabrics. The fill material is firmly and tightly packed into cover 34, such that the core and cover 34 together provide a self-supporting pillow body, i.e., the support pillow 10 retains its shape without any sagging or drooping of arms 18 and 20 when held at the medial region 15. The tightly packed fill material forming core also provides the pillow with firmness in the sense that it will undergo only slight elastic deformation (as compared to a conventional pillow) when the pillow rests on an object (such as a person's legs). Other fill materials that could be used include natural or synthetic fibers, synthetic beads, feathers, foam, and organic granular fill materials such as husks and seeds and the like.
In the embodiments shown, cover 34 is formed of multiple pieces of fabric, it being appreciated that cover 34 could be constructed in other ways as well. For convenience of discussion, cover 34 can be described in terms of three major components: a top piece 40 (which forms a top surface), a bottom piece 42 (which forms a bottom surface), and a center panel 44. Examples of materials that may be used for top piece 40 and bottom piece 42 include cotton fabrics, polyester fabrics, cotton/poly blends and the like. By using such materials for the top piece 40 and bottom piece 42, various conventional fabrics may be used to provide a comfortable, decorative and aesthetically pleasing surface. Although shown with top piece 40 and bottom piece 42, it will be appreciated that a single piece of fabric or multiple pieces may be used to cover the top and bottom of the pillow. Sewn to top piece 40 and bottom piece 42 is center panel 44. In this way, center panel 44 surrounds the inner well 16 and the outer periphery and eliminates a seam running along the mid-plane. Although the pieces may be sewn together, other techniques may also be used, such as by using glue, lacing, staples, snaps and the like. The configuration the center panel 44 makes the pillow sufficiently resilient to spring arms 18 and 20 back to their original shape.
As best shown in
Stiffening layer 53 will typically be coextensive with top surface 21 and thus extend along medial region 15 as well as ends 18 and 20. Stiffening layer 53 may be constructed of a dense foam, such as a polyurethane foam with a high IFD, or Indentation Force Deflection. The acronym IFD refers to the hardness or softness of the foam. For example, the higher the IFD, the firmer the foam. IFD is defined as the amount of force, in pounds, required to indent a fifty square inch, round indentor foot into a predefined foam specimen a certain percentage of the specimen's total thickness. IFD is specified as the number of pounds at a specific deflection percentage on a specific height foam sample, e.g., 25 pounds per 50 square inches at a 25% deflection on a four inch thick piece.
In some embodiments, the IFD may be at least 20, and in some cases greater than about 30 and in other eases in the range from about 30 to about 45.
Stiffening layer 53 may also have a thickness in the range from about 0.5 inch to about 3 inches. Also, in some cases, multiple foam pieces or other stiffening materials could be stacked on each other to form layer 53.
To facilitate construction, stiffening layer 53 may be sewn or otherwise attached to top piece 40. Further, various stitching patterns in top piece 40 may be employed.
As shown in
Although shown integrated into pillow 10, it will be appreciated that stiffening layer 53 could be removably attached to pillow 10 so that it could be removed when needed. For example, cover 34 could include a sleeve or pocket into which stiffening layer 53 is inserted. The pocket could include one or more fastening mechanisms to secure stiffening layer 53 within the pocket. For example, the pocket could have a zipper that is used to close an opening through which stiffening layer 53 is inserted. Also, stiffening layer 53 may be sized, shaped or otherwise configured to be similar to any of the other inserts and/or stiffening members described herein.

Pillow body 130 may be formed in a variety of ways. In the embodiment shown, cover 134 is formed of multiple pieces of fabric that are sewn together. However, it will be appreciated that cover 134 may be constructed of various pieces of fabric that are sewn or otherwise connected together in ways other than those illustrated in the specific embodiments. For convenience of discussion, cover 134 may be described in terms of the following major components: a type piece 140 (which forms a top surface), a bottom piece 142 (which forms a bottom surface) and a side panel 144 which extends around the sides of pillow body 130. These various fabric pieces may be constructed using any of the fabrics described herein. By using such materials for top piece 140, bottom piece 142 and side panel 144, various conventional fabrics may be used to provide a comfortable, decorative and aesthetically pleasing surface. Importantly, by constructing pillow 100 in this manner, pillow body 130 may be washed using conventional techniques. For example, pillow body 130 may be placed in a conventional washing machine and washed in a gentle cycle. In this way, if pillow body 130 becomes soiled, it may be easily cleaned by simply using a washing machine.

One particular advantage of using a removable support member 148 is that support member 148 may be removed when not needed. This may occur for a variety of reasons. For example, support member 148 may be constructed of a material that is not suitable for a conventional washing machine. Hence, support member 148 may be removed from pocket 146 prior to placing feeding pillow 100 into a conventional washing machine. Also, different shapes, sizes, and firmnesses of support members may be interchanged within pocket 146. In this way, the shape and feel of top surface 121 may be varied simply by varying the type of support member 148 that is placed within pocket 146. Finally, in some cases feeding pillow 100 may be used without any type of support member 148. In this way, pocket 146 may be left empty while feeding pillow is in use. Still further, while support member 148 has been described as being able to be coupled to feeding pillow 100 using pocket 146, it will be appreciated that other techniques may be used. For example, a separate slip cover with or without a pocket may be placed over some or all of pillow body 130 to hold support member 148 to top surface 121. Other techniques tor holding support member 148 to pillow body 130 include ties, clips, buttons, a hook and loop fastener material, and the like.
One particularly advantageous use of support member 148 is that it may be used to provide a more firm support surface for holding an object than is provided by pillow body 130. As previously described, pillow body 130 may be filled with a fill material 137 that is somewhat soft and pliable. In some cases, it may be desirable to have one of the surfaces, such as top surface 121, with a firmness that is different from pillow body 130. For example, support member 148 could be constructed of a material that is either more firm or less firm than the firmness provided by fill material 137. In many cases, it will be desirable to have support member 148 having a firmness that is greater than the firmness provided by pillow body 130. Such may be the case when feeding or nursing a baby where feeding pillow 110 rests upon a user's lap. Advantages of such a firmness are also described herein with reference to the embodiment of
Another particularly advantageous use of support member 148 is that it may be shaped to accommodate different uses. As shown in
The angling of the baby while feeding may be thought of in terms of providing top 160 of support member 148 with an angle of inclination. Although shown with a contoured top 160, this angle may be defined in terms of a straight line or plane extending from lip 168 to inner periphery 166. This angle is relative to bottom 162. The angle of inclination as just defined may be in the range from about 20 degrees to about 35 degrees, and in some cases about 25 degrees to about 33 degrees. This so-called “angle” is particularly critical in orienting the baby at the appropriate position to facilitate nursing. Such an orientation of the baby may be provided using other geometries, and not necessarily by using lip 168 and recessed region 170. For example, top 160 could be planar or may include other surface contours to help appropriately angle or position the baby. Further, bottom 162 could also include contours, such as being roughened or include scallops or other surface treatments to help adhere support member 148 to pillow body 130.
As previously described, support member 148 may be configured to be more firm than pillow body 130. This may be accomplished by constructing support member 148 out of a dense foam material, such as a polyurethane foam with a high IFD. The IFD may be similar to that described in connection with other embodiments. The polyurethane foam material may be open cell or closed cell and may therefore include a skin as is known in the art. Support member 148 may be formed using a molding process or may be surface modified using surface modification equipment as is known in the art. Other types of materials that may be used to form support member 148 include viscoelastic materials, gels, inflatable bladders, fill materials encased within fabrics, and the like.

Support member 148 may be sized to be slightly smaller in outer dimensions than pillow body 130 so that it may fit within pocket 146. In the embodiment shown in
Support member 148 includes rounded edges that pass over arms 118 and 120 when support member 148 is within pocket 146. As such, support member 148 does not include arms in the sense that feeding pillow 100 includes arms. This configuration may be used to facilitate inserting of support member 148 into pocket 146. Also, the absence of any arms may also help to position or orient the baby when feeding as previously described.
