Abstract
The present disclosure provides a pillow insert. The pillow insert includes a plurality of sleeves, wherein each sleeve is substantially filled with a soft material and attached to an adjacent sleeve at least at one end and partially or completely unattached along an adjacent side. Each sleeve is substantially against the adjacent sleeve such that a pillow surface is provided. Also provided is a pillow assembly comprising the pillow insert, a padding component, and a cover.
Description
- The present application claims the benefit of U.S. Provisional Patent Application No. 62/867,400, filed Jun. 27, 2019, the disclosure of which is incorporated by reference herein in its entirety.
- The present disclosure provides a pillow insert. The pillow insert includes a plurality of sleeves, wherein each sleeve is substantially filled with a soft material and attached to an adjacent sleeve at least at one end and partially or completely unattached along an adjacent side. Each sleeve is substantially against the adjacent sleeve such that a pillow surface is provided. Also provided is a pillow assembly comprising the pillow insert, a padding component, and a cover.
- Pillows serve to keep the user's upper body in alignment during sleep, relieving pressure and counterbalancing points in the body. A proper pillow not only enhances user's sleep but also provides adequate support for supporting the user's head, neck, shoulders, hips, and spine, thereby preventing or alleviating back and neck pain and stiffness. Pillows should adjust to fit the user's body shape and sleeping habits, and standard-sized pillows may not be suitable as a “one size fits all” model.
- For example, for back and neck sleepers, a thicker pillow may cause the neck to become misaligned with the spine by pushing the neck too far forward or back. In some cases, a thinner pillow may allow the neck to maintain at a neutral angle and provide better rest.
- Challenges associated with the production of thin pillows include forming an even, flat surface, preventing the pillow filling from forming clumps, and preventing the pillow from sinking substantially upon applying pressure. For improved comfort and experience, a pillow should have few seams which can be felt by the user, which has the additional benefit of preventing lines or marks left on the user in contact with the pillow.
- Embodiments of the present disclosure provide a pillow insert and pillow assembly including a substantially flat planar pillow surface upon application of pressure.
- In some embodiments, the present disclosure is directed to a pillow insert including a plurality of sleeves, wherein each sleeve is substantially filled with a soft material and attached to an adjacent sleeve at least at one end and partially or completely unattached along an adjacent side, wherein each sleeve is substantially against the adjacent sleeve such that a pillow surface is provided.
- In further embodiments, the present disclosure provides a pillow assembly including a pillow insert comprising a plurality of sleeves, wherein each sleeve is substantially filled with a soft material and attached to an adjacent sleeve at least at one end and partially or completely unattached along an adjacent side, wherein each sleeve is substantially against the adjacent sleeve such that a pillow surface is provided; a padding component arranged on at least one outer side of the pillow insert; and a cover, wherein the pillow insert and the padding component are encased in the cover.
- In still further embodiments, the present disclosure provides a pillow assembly including a pillow insert comprising a plurality of sleeves, wherein each sleeve has a shape of a cylindrical tube, is substantially filled with a soft material, and each sleeve is attached to an adjacent sleeve at a first end and unattached along each adjacent side, wherein each sleeve is substantially against the adjacent sleeve such that a pillow surface is provided; a first padding component substantially covering a first outer side of the pillow insert; a second padding component substantially covering a second outer side of the pillow insert; an inner cover configured to encase the pillow insert and the first and second padding components to limit movement therebetween; and an outer cover configured to encase the inner cover, wherein the pillow assembly is about 2 to about 3 inches in height in an uncompressed state.
- The foregoing and other features and advantages of the invention will be apparent from the following description of embodiments hereof as illustrated in the accompanying drawings. The accompanying drawings, which are incorporated herein and form a part of the specification, further serve to explain the principles of the invention and to enable a person skilled in the pertinent art to make and use the invention.

In other embodiments, the pillow insert is part of a pillow assembly, and the pressure is applied to theouter sides 114 of the plurality of sleeves via contact to the pillow assembly. In yet further embodiments, the pillow assembly is covered, and the pressure is applied to theouter sides 114 of the plurality of sleeves via contact to the covered pillow assembly. The amount and/or method of applying the pressure is not limited, so long as the pressure is not too great such that the sleeves burst, thereby breaking the pillow insert and/or pillow assembly. The amount of pressure required to burst the sleeves, or to break the pillow insert and/or pillow assembly, can be determined by one of ordinary skill in the art. - As used herein a “pillow surface” refers to a structure that is any shape shorter in height than in width and depth, suitable for use in sleeping. By “substantially flat planar pillow surface,” it is meant that the
pillow insert 110 varies in height PH (seeFIG. 7 ) by less than 25%, preferably less than 20%, or more preferably less than 10% across the entire length and width of the pillow insert. Thus, a user of a pillow assembly having the pillow insert would not feel bumps or ridges on the pillow surface. - Advantageously, the pillow surfaces provided herein, and suitably the substantially flat planar pillow surface, provides neutral alignment of the user's head, neck, and spine when resting on the pillow assembly. In some embodiments, the pillow insert is about 2 to about 3 inches in height PH (see
FIG. 7 ) in an uncompressed state. In alternate embodiments, the pillow insert is about 3 to about 6 inches in height PH in an uncompressed state. In further embodiments, the pillow insert is about 2 to 6 inches, about 2 to 5 inches, about 2 to 4 inches, or about 2 to 3 inches in height PH in an uncompressed state. In further embodiments, the pillow insert is about 2, about 2.25, about 2.5, about 2.75, about 3, about 3.5, about 4, about 4.5, about 5, about 5.5, or about 6 in height PH in an uncompressed state. In embodiments, the pillow insert does not change substantially in height in a compressed state compared to the uncompressed state, i.e., the pillow insert changes in height by less than about 40%, less than about 35%, less than about 30%, less than about 25%, less than about 20%, less than about 15%, less than about 10%, or less than about 5% when compressed from the uncompressed state. - A further benefit provided by the
pillow insert 110 of the present invention is the lack of seams felt by the user, which provides increased comfort and also does not leave undesirable marks or lines on the skin of a user, which may occur when using pillows that have seams either on the pillow cover or pillow insert. In embodiments, with each sleeve being substantially against an adjacent sleeve of the pillow insert, the pillow surface is substantially seamless. Accordingly, in some embodiments, upon applying pressure to one or moreouter sides 114 of the plurality of sleeves of the pillow insert, the substantially flat planar pillow surface is substantially seamless. As used herein, “substantially seamless” means that seams are not visible in the surface of the pillow assembly, and/or that seams are not felt by a user of the pillow assembly, or that seams can be felt, but at a minimal level such that the comfort of the user is not impacted, or that seams do not leave marks or lines on the skin of a user. In embodiments, the pillow inserts do not comprise any seams at their adjacent sides, and are prepared from a single piece of continuous fabric such that no seams are visible or can be felt at the adjacent sides. - As shown in
FIGS. 1-5 ,sleeves 110 can have any suitable shape. In embodiments, each sleeve has a shape substantially of a triangle, a rectangle, a square, a hexagon, an octagon, a cylindrical tube, or a cross. In an embodiment, each sleeve has the shape of a cylindrical tube (see, e.g.,FIG. 1 ). In general, a cylindrical tube suitable for thepillow sleeves 110 has a substantially circular cross-section and has a length typically greater than its diameter, e.g. the length of the cylindrical tube is longer than the diameter by about 10% or more, about 50% or more, about 100% or more, about 150% or more, about 200% or more, or about 500% or more. In embodiments, the length of the cylindrical tube is about 2, about 3, about 4, about 5, about 6, about 7, about 8, about 9, or about 10 times the diameter of the cylindrical tube. In another embodiment, each sleeve has the shape of a triangle (see, e.g.,FIG. 4 ). Further exemplary embodiments of sleeve shapes are illustrated inFIGS. 5A-5F . The sleeves may have any shape, so long as they are capable of being attached at least at one end, partially or completely unattached along an adjacent side, and, upon applying pressure to one or more outer sides of the plurality of sleeves, each sleeve under pressure presses against the adjacent sleeve such that a substantially flat planar pillow surface is provided. As described herein, in embodiments, the pillow inserts do not comprise any seams at their adjacent sides, and each insert is prepared from a single piece of continuous fabric (or otherwise manufactured) such that no seams are visible or can be felt at the adjacent sides. - In additional embodiments, the lengths of
sleeves 110 can be varied such that different shapes can be created (e.g., crescent, curves (seeFIG. 9 ), shell-shapes, circular shapes, etc.) as may be desired or beneficial as a pillow surface. In further embodiments, the diameter and/or thickness ofsleeves 110 can be varied throughout the pillow insert, and connected with different height sleeves, so as to generate contour-shaped pillow surfaces, etc. (seeFIG. 10 ). -
Attachment point 118 between adjacent sleeves can be positioned at any suitable end of each sleeve. In some embodiments, eachsleeve 110 is attached to an adjacent sleeve at a same end, e.g., as illustrated inFIG. 2 , wherein eachsleeve 110 is attached to an adjacent sleeve at afirst end 116. In other embodiments,sleeves 110 are attached to one another at alternating ends, e.g., as illustrated inFIG. 3 , showing that a first sleeve of the plurality of sleeves is attached to a second sleeve viaattachment point 118 at afirst end 116; the second sleeve is then attached to a third sleeve viaattachment point 118 at asecond end 115; etc. This alternating attachment can continue throughout the entire pillow insert length (longitudinal axis (LA)). - In further embodiments, the sleeves are attached to one another at a
first end 116 and asecond end 115. For example, each sleeve is attached to an adjacent sleeve atfirst end 116 andsecond end 115. In some embodiments, the sleeves are attached to one another at the first and/or second ends in any combination or configuration. For example, each sleeve in the plurality of sleeves may be attached to an adjacent sleeve at afirst end 116, asecond end 115, or both ends 116 and 115, in any combination, throughout the entire length (longitudinal axis (LA)) of the pillow insert. - According to certain embodiments illustrated herein, e.g., in
FIGS. 1-4 , each sleeve is completely unattached along anadjacent side 112. In these embodiments, each sleeve is not forced to move along the longitudinal axis LA even when its adjacent sleeve may be moving or expanding along LA, thus allowing each sleeve to be substantially against an adjacent sleeve, and to press against the adjacent sleeve when under pressure and form a pillow surface and suitably a substantially flat planar pillow surface. - In further embodiments, a
sleeve 110 may be partially attached to an adjacent sleeve along anadjacent side 112. For example, as illustrated inFIG. 5C , an adjacent point ofattachment 150 can exist along anadjacent side 112 between each sleeve and an adjacent sleeve. In such embodiments,sleeves 110 are still capable of expanding and/or moving along the longitudinal axis LA without forcing an adjacent sleeve to move along LA, thus allowing each sleeve to be substantially against an adjacent sleeve, and to press against the adjacent sleeve when under pressure and form a pillow surface and suitably a substantially flat planar pillow surface. - Methods of attaching a sleeve at
attachment point 118 to its adjacent sleeve can be selected by the ordinarily skilled artisan. In some embodiments, the ends of the sleeves are directly sewn together. For example, when the sleeves have corners at their ends, the corner of one sleeve may be sewn to the adjacent corner on the adjacent sleeve. In further embodiments, the sleeves are attached via a connecting means. Non-limiting examples of connecting means include, e.g., a ribbon, thread, rope, or a length of fabric material that spans the ends of the sleeves to be attached; or a fastener at the ends of the sleeves to be attached, such as hook and loop fasteners, magnets, buttons, snapping fasteners, clips, and the like. In embodiments wherein the adjacent sides of the sleeves are partially unattached, any means of attachment provided herein is suitable for partial attachment of the adjacent sides.FIGS. 5A-5C also illustrate exemplary locations of attachment points 118 of eachpillow insert 110. - In embodiments, the plurality of
sleeves 110 are arranged adjacent to one another along longitudinal axis LA across thepillow insert 100, i.e., the sleeves are not stacked such that theirouter sides 114 are in contact with one another, but are placed such that adjacent sides are substantially against each other to provide a pillow surface. Accordingly, in embodiments wherein pressure is applied to one or moreouter sides 114 of the plurality ofsleeves 110, each sleeve under pressure presses against the adjacent sleeve along anadjacent side 112, thereby providing a substantially flat planar pillow surface across LA. - The plurality of
sleeves 110 are substantially filled with a soft material. Any suitable soft material filing may be used for the present invention. In some embodiments, the soft material comprises polyester fiberfill, down, feather, foam (e.g., shredded memory foam), or combination thereof. Further exemplary soft materials for filling the plurality of sleeves include, but are not limited to, buckwheat hull, microbead, shredded latex, kapok, cotton, gel, wool, and the like. Any combination of the materials described herein can be used to fill the plurality of sleeves, and each sleeve in the plurality of sleeves may be filled with the same or a different material. As described herein, the amount of material filled into sleeves can also be varied to create different shapes or contours of pillows as desired. - In some embodiments, provided herein is a pillow assembly, comprising: a pillow insert comprising a plurality of sleeves, wherein each sleeve is substantially filled with a soft material and attached to an adjacent sleeve at least at one end and partially or completely unattached along an adjacent side, wherein each sleeve is against the adjacent sleeve to provide a pillow surface. Suitably, upon applying pressure to one or more outer sides of the plurality of sleeves, each sleeve under pressure presses against the adjacent sleeve such that a substantially flat planar pillow surface is provided. The pillow assembly suitably further comprises a padding component arranged on at least one outer side of the pillow insert; and a cover, wherein the pillow insert and the padding component are encased in the cover.

FIG. 6 . InFIG. 6 ,pillow assembly 200 includespillow insert 100 comprising a plurality ofsleeves 110, as described herein, andpadding component 120. Thepadding component 120 may be substantially filled with a soft material orpadding component 120 may itself be made directly of a soft material. In embodiments, the padding component comprises polyester fiberfill, down, feather, foam (e.g., shredded memory foam) or combination thereof. Further exemplary soft materials for the padding component are provided herein and include, but are not limited to, buckwheat hull, microbead, shredded latex, kapok, cotton, gel, wool, and the like. In some embodiments, thepadding component 120 andsleeves 110 comprise the same soft material. In other embodiments, thepadding component 120 andsleeves 110 comprise different soft materials. - In some embodiments, e.g., as illustrated in
FIG. 6 ,padding component 120 is arranged on an outer side of thepillow insert 100. The outer side of the pillow insert comprises the surface formed by theouter sides 114 of the plurality of sleeves. In embodiments, thepadding component 120 substantially covers theouter side 114 of thepillow insert 100. By “substantially covers,” it is meant that at least 80% of the surface area formed by theouter sides 114 of the plurality of sleeves of thepillow insert 100 is covered by thepadding component 120. In some embodiments, “substantially covers” means that at least 80%, at least 85%, at least 90%, at least 95%, or about 100% of the surface area formed by theouter sides 114 of the plurality ofsleeves 110 of thepillow insert 100 is covered by thepadding component 120. - Each sleeve of the plurality of sleeves in the pillow insert comprises two
outer sides 114. When viewing the pillow insert in a top-down view such as inFIG. 2 , firstouter side 114 a of the plurality of sleeves faces the viewer, while the secondouter side 114 b faces away from the viewer. Thus, in some embodiments,padding component 120 is arranged on both a firstouter side 114 a and a secondouter side 114 b of the pillow insert. In certain embodiments,padding component 120 is configured to fold along the length of one end of the plurality of sleeves so as to be arranged on both firstouter side 114 a and secondouter side 114 b of the pillow insert (i.e.,padding component 120 is a continuous padding layer). In alternative embodiments,padding component 120 comprises a first padding component and a second padding component (i.e., separate components). In such embodiments, the first padding component substantially covers the firstouter side 114 a of the pillow insert, and the second padding component substantially covers the secondouter side 114 b of the pillow insert. - Cover 132 according to embodiments herein is illustrated in
