Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims benefit to provisional application 60/586,022, filed on Jul. 7, 2004, entitled “Comfort Pillow”, which is incorporated herein in its entirety.

FIELD OF THE INVENTION

The present invention relates to the field of pillow designs, and in particular to a breathable pillow stuffed with pellets.

BACKGROUND OF THE INVENTION

In a struggle to design the perfect pillow, inventors and companies have developed pillows with stuffing ranging from cotton and synthetic materials to bird feathers and buckwheat. In each of these applications at least one problem exists with the designs; these problems include heat retention, noise, structural degradation in a short time span, and uneven compression. As a result, numerous pillow fillings have been introduced into the market in an attempt to create the perfect pillow.
U.S. Patent Application No. 20030200609 discloses a cushioning device. The cushioning device has a flexible container and a plurality of polymeric beads within the flexible container which flows under a slight force and shears easily. The cushioning device is capable of receiving a physical object that applies a force to the cushion. When the force is initially applied to the cushioning device, the cushioning device is deformed to conform to the physical object from its original shape. When the physical object is not applying the force, the cushioning device reverts to a shape that is close to but not identical to the original shape, except for a limited number of materials such as molded elastomeric materials. In addition, the pressure exerted by the cushion on the physical object will reduce pressure that would cause tissue damage and lead to decubitus ulcers.
U.S. Pat. No. 6,235,391 discloses a resilient material shaped into a bent strand with a preferred length from 1.5 to 7 inches forms a filling element for cushions, pillows and upholstered articles. The strand may be bent so as to have a Z-shape or an S-shape or a V-shape or a C-shape along a portion of its length. The length of the strand is greater than its nominal cross-sectional thickness. A quantity of filling elements (e.g., the filling material), preferably formed from flexible, open cell polyurethane foam, is inserted or blown into a casing for a cushion, pillow or upholstered article. Following compression, the filling elements rebound substantially to their uncompressed state without clumping together or leaving pockets within the casing.
U.S. Pat. No. 5,778,470 discloses a pillow structure formed with an outer cover or casing in which a foam shell is enclosed, where in a horizontally disposed partition being mounted in the shell along the horizontal central axis of the pillow structure, wherein the partition controls the random movement of beads enclosed within each compartment defined by the partition, whereby the beads are prevented from moving or being transferred between the respective juxtaposed compartments.
U.S. Pat. No. 4,307,200 discloses a composite foamed material and a process for the production thereof are disclosed herein, the process comprising premixing expandable or expanded polystyrene beads, a binder and fragments of resilient, open-celled neoprene. The materials are combined in the proportions of about 4-15% polystyrene beads, about 6-25% binder and about 60-90% open-celled neoprene. The combined materials are preferably compressed to a density of about 5-30 lbs. per cubic foot, more preferably 5-17 lbs. per cubic foot, and steam is applied to the compressed materials to cure the binder, and in certain embodiments to expand the polystyrene beads, thereby producing the desired composite foamed material.
U.S. Pat. No. 3,999,801 discloses a seating structure removably receives a typically amorphous styrofoam pellet-filled body cushion. The seating structure includes a shell for holding the cushion and a pedestal for supporting the shell on a floor surface. In the preferred embodiment the shell has a bottom portion, rear support, side and front portions integral with, and extending generally upward from, said bottom to define a contoured and shaped cushion-receiving cavity. The shell is generally concavo-convex in shape with the pedestal attached to the convex underside of the shell. The pedestal is additionally adapted to removably receive casters or detachable base supports.
U.S. Patent Application No. 20040019972 discloses a cushioning apparatus such as a pillow which includes an upper pocket with reception cavity for receiving preferably loose or grouped non-integral filler material such as down, fiberfill or fiber-balls and another pocket for receiving additional filler material such as a foam core filler material. The foam core filler material is preferably an integrated or monolithic foam body of, for example, visco-elastic or alternate polyurethane foam. The core preferably has a non-planar upper surface contour allowing for a relatively thin, consistent height upper pocket thickness. The pillow also preferably includes a lower pocket joined about its periphery to the upper pocket such as by way of an intermediate gusset panel with beading and with the lower pocket also receiving loose or non-integrated filler material and with the bottom surface of the core preferably having a convex surface such as one symmetrical with the top surface.
There is a need however, for a breathable comfort pillow that does not retain heat, while being hypoallergenic, durable, silent, and extremely comfortable.
