Definitions

  • the present invention relates generally to pillows.
  • the present invention relates to mouldable pillows which adjust to provide consistent support to a user.
  • Pillows are used not only by humans, but also may be used by domesticated animals, such as dogs and cats.
  • pillows provide physical support to the head, neck and shoulders. This support assists in maintaining their alignment and relieving stress and. strain.
  • An adult human head weighs approximately 10 pounds, constituting about 8% of the entire body weight. To support this weight, the human neck bends slightly forward.- It is important that this natural curvature be maintained while resting on a pillow. .
  • a pillow that is too high may cause muscle strain in the back of the neck and. in the shoulders, because the neck is bent forward or to the side, which may result in obstruction of the trachea, reduced breathing and snoring.
  • a pillow that is too low can also lead to strained neck muscles.
  • a pillow are that it should provide comfort to the user and that it should provide therapeutic support to hold the user's head, neck, shoulders or entire back in a healthy orthopaedic position to allow the muscles, nerves and spine to relax.
  • Conventional pillows consisting essentially of a compressible filling material such as avian down, synthetic feathers or various foam materials encased in a cover made from one of a variety of non-elastic fabrics do not do so.
  • the conventional pillow makes "support” and "comfort” contradictory. While using such a conventional pillow, a user's body weight and body shape will compress the compressible filling. While a soft pillow may provide increased comfort, the softer the filling of a conventional pillow, the less support. Though a firm pillow my provide increased support, the firmer the conventional pillow, the less comfortable most users will find it.
  • Pillow fillings may be composed of a variety of foam materials such as polyurethane. Pillows have been formed into a distinctive contour to address different therapeutic support requirements. For example, some prior art pillows are designed to have greater height at the left and right sides and lesser height in the centre. Other prior art pillows are higher on one side and lower on the other. While such improved conventional pillows provide improved side or back support over standard conventional pillows, none of them are of a shape that is suitable for all pillow users.
  • buckwheat is a natural grain product with a coarse exterior.
  • the buckwheat hulls are substantially non-c ⁇ mpressible, under pressure from the weight of a pillow user the hulls would move with the motion of the user lying on the pillow.
  • buckwheat pillow provided- improved support, buckwheat pillows were considered to be very uncomfortable.
  • the buckwheat hulls became crushed and disintegrated.
  • the buckwheat filling emitted an oily, odorous substance, the movement of the buckwheat hulls produced considerable noise, and the filling was not washable.
  • EPS microbeads are made of expandable polystyrene (EPS), a known synthetic material derived from petroleum, EPS microbeads resolve many of the issues associated with buckwheat filling. Food-grade EPS has no odor. EPS microbeads are solid and, as their 97% air content is encapsulated in a closed cell bead, they are substantially non- compressible in the context of normal pillow use.
  • prior art EPS microbeads have a high surface friction that causes some noise when they move against other microbeads or a supporting surface.
  • EPS generates a high static electric load which causes the microbead filling to illuminate. Such illumination may be very disturbing to people moving on their pillow at night.
  • Microbead filling is substantially non-compressible and does not disintegrate with ⁇ normal use over time. Rather than compressing when body weight is applied, the microbeads move inside the pillow cover.- This results in the beads moulding around the anatomy of a user's body. Such individualized moulding provides much improved therapeutic support in any sleep or resting posture.
  • the . microbeads in prior art microbead pillows may prematurely move into an available space of the pillow cover, causing loss of the desired therapeutic support If the pillow is overfilled or encased in a tight pillowcase, the pillow may become overly firm and uncomfortable. To provide comfort and make the pillow function properly, the pillow cover and pillowcase should be made of an elastic material.
  • microbead pillow covers and pillowcases are made of a polyester spandex fabric, As many users prefer a natural fabric such as cotton for comfort reasons, microbead pillow covers or cases often are made of spandex on one side and a cotton blend on the other. As cotton fabrics are only 2-way stretchable, prior art microbead pillows using cotton-based pillowcases or pillow covers do not function well.

  • microbead fillings have the advantage of movement within the pillow cover, and the microbeads do not compress.
  • the movement of the beads is triggered by force applied to ' cause motion of the bulk of the beads. .
  • the motion ceases, causing the microbeads to lock-up arid act like a solid.
  • This locking effect is analogous to a sand structure.
  • the sarjd particles, like the beads, have extensive surface contact with other sand particles and act as a solid until the application of force causes the structure to collapse.
  • This same effect in a conventional microbead pjllow is highly undesirable, as the pillow feels hard when, the user's body is not moving.
  • microfibres with the microbeads to form a complex filling inhibits clustering of the microbeads into a static unit.
  • the microfibres provide absorption of forces, acting as microscopic shock absorbers in the complex filling. Minor motion of the pillow user causes the filling to move, dynamically adjusting and readjusting to the changing body shape and position,

  • the microfibres are approximately 10 microns in diameter.
  • the microfibres have near zero surface friction. They may be spun into spherical clusters of approximately 5 mm and mixed with the rnicrobeads into a complex filling. Once mixed with the microbeads, the microfibres form a web throughout the pillow which constrains bulk movement of the microbeads. as illustrated in Fig. 4. However, smaller volumes of microbeads would still be still displaceable throughout the pillow.
  • prior art microbead pillows with no additional component tb restrict flow of the microbeads, have the disadvantage of permitting dislocation of large volumes of microbeads in response to pressure exerted on the pillow by a user 14.
  • the beads may congregate in areas 16, 16, 20 of the pillow where there is available volume, resulting in a loss of desired therapeutic support.
  • Another effect of this mass dislocation of microbeads is the wrapping of the pillow around the neck, which may cause obstruction of the trachea or may induce or worsen snoring.
  • the microbead-microfibre complex filling of the present invention adjusts dynamically to the body shape and motion of the user 14 without causing bulking 1 of the filling.
  • the high surface friction of EPS beads in prior art microbead pillows may cause noise as the microbeads move against one another.
  • the addition of microfibres ' helps to reduce the rustling noise as the microfibres inhibit mass simultaneous movement of the microbeads,
  • the surface friction of the microbeads. can be reduced by applying an antistatic coating to the microbeads.
  • a variety of such antistatic chemicals are well known in the textile industry for use in eliminating static load on fabrics. The chemical has not previously been applied to microbeads. Microbeads treated with an antistatic coating are available from Sekusi Plastics Co. Ltd. of Tokyo; Japan.
  • the application of the antistatic coating results in a significant reduction of the surface friction of the microbeads and the surface of the beads becomes extremely slippery. As a result, movement of the microbeads within the pillow produces much less noise than is produced by microbeads which have not been treated with this antistatic chemical.
  • the reduced surface friction caused by application of the antistatic coating to the microbeads not only reduces the noise generated by the microbeads moving relative to one another, but also inhibits locking up in the absence 'of applied force and rapid unlocking upon application of feree which is characteristic of prior art microbead fillings.
  • High static electricity can be generated by rubbing EPS microbeads together. Discharge of this electric load results in illumination of the filling, which may be disturbing to pillow users. This electrostatic load also causes the microbeads to be attracted to each other, the surrounding fabric and the microfibr ⁇ s.
  • Application of the antistatic coating to the microbeads eliminates the generation of electrostatic loads inside the pillow, preventing the illumination caused by discharge of the electrostatic load, improves the independent movement of the microbeads, and prevents the microbeads from adhering to one another or ths microfibres.
