1. Field of the Invention
This invention relates, generally, to a support material for a pillow or for slippers. More particularly, it relates to support material a having an hourglass shape.
2. Background Art
U.S. patent application Ser. No. 11/175,681 discloses a comfort pillow having a pellet filling. The pellet filling has a plurality of spherical hot stamped pellets, whereby, small fibers are connected to each neoprene pellet. The small fibers extend from the surface of each neoprene pellet. It would be more desirable for the support material to provide more comfort to a user and to increase airflow circulation around the support material to have a cooling effect. Thus, there is a need for a support material having an hourglass shape. This improved support material shape eliminates the need for the introduction of miniature fibers onto the pellet during the hot stamping process which drastically reduces costs of manufacturing.
Currently, commercially available support material for pillows includes open-celled foam or feathers. These pillows may not maintain their original shape after repeated use from a user. Additionally, many pillows contain support material that cannot withstand being washed in a washing machine without destroying the shape of the pillow, thereby, rendering the pillow useless for supporting a user. Thus, there is a need for a support material capable of being washable so that the pillow can be sanitized while maintaining the intended pillow shape.
Previously, certain support materials used for filling an object such as a slipper cannot maintain the shape of the slipper after being subjected to the force from the weight of a user standing on the slipper. For instance, the support material of a slipper being a single layer of foam will conform to the shape of a user's foot as the weight is forced upon the support material. However, eventually over time, the foam loses its structural ability to reform it's original shape when a user removes the force from their body weight from the support material. What is therefore needed is a support material capable of supporting a user and maintaining the shape of the object being filled after repeated use of the object by a user.
However, in view of the prior art considered as a whole at the time the present invention was made, it was not obvious to those of ordinary skill in the pertinent art how the identified needs could be fulfilled.
The long-standing but heretofore unfulfilled need for a support material having an hourglass shape, the support material includes a primary end having a primary diameter located opposite a secondary end having a secondary diameter, a substantially central portion has a tertiary diameter being a size less than the primary and secondary diameters, an outer wall surface of the support material has at least one recess, the at least one recess can retain a substance such as a cooling gel which also includes improvements that overcome the limitations of prior art support materials is now met by a new, useful, and non-obvious invention.
The novel support material has a primary end located opposite a secondary end. The primary end has a primary diameter. The secondary end has a secondary diameter. The support material has a substantially central portion having a tertiary diameter. The tertiary diameter has a size less than the primary diameter. The tertiary diameter has a size less than the secondary diameter forming an hour glass shape.
In a preferred embodiment, the support material is made of a closed celled material, including, but not limited to neoprene foam or neoprene rubber. A closed celled material is capable of being washed and dried. For example, a pillow or slippers that are filled with the novel support material being of a neoprene material can be washed and dried without damaging the shape or without negatively altering the comfort level of the pillow or slippers. Although not a preferred embodiment, the support material is made of an open celled material, including but not limited to, polyurethane foam or rubber.
It is within the scope of this current invention for the support material to be a pellet having an hour glass shape. It is a preferred embodiment for each pellet to have a primary end and a secondary end having a size between 8 mm-12 mm in diameter, a substantially central tertiary portion having a diameter being less than both the primary end and the secondary end, and to have a pellet length of approximately 20 mm. In an alternate embodiment, the pellet length has a range from 2 mm to 100 mm and a height ranging from 2 mm to 50 mm. For example, a novel pellet having a smaller size is more comfortable for a user when used as a filling material for a slipper or a neck pillow. A novel pellet having a larger size is more comfortable for a user when used as filling material for a pet bed or a bean bag chair. It is within the scope of this invention for the support material to be manufactured by a heat stamp process.
In a preferred embodiment, a plurality of novel pellets having an hour glass shape are capable of filling any conformable object including, but not limited to, a pillow, a spa pillow, neck pillow, lumbar support pillow for the office, a pet bed, a sleeping pillow a slipper, a bean bag chair, padding for a helmet, any padding, shoes, sandals, a chair cushion, or a floor pad. It is within the scope of this invention for the novel pellets to be retained within one compartment of a conformable object.
In a second embodiment, the novel support material having an hourglass shape can have at least one recess located on an outer wall surface of the support material. The at least one recess can facilitate in air circulation around the novel support material by the formation of pockets of cooler air. The at least one recess can retain a substance including, but not limited to, a gel or scented oil. This gel could have a cooling effect on a user and can increase user comfort when a user's force is applied to the supporting material. For instance, when a user's head is leaning upon a pillow filled with the novel support material or when a user's foot is standing on a slipper filled with the novel support material. It is within the scope of this invention for the substance to be aromatic. The novel support material having a scented substance is beneficial in eliminating odor from slippers and the aroma therapy aspect of the scent can facilitate in the relaxation of a user in close proximity to an object retaining the novel support material.
