Description
TECHNICAL FIELD OF INVENTION
[0001] This invention relates mainly to a long-filament fiber
memory foam pillow, in particular, it relates to the long-filament
fibers inner tube covers on a foam unit having egg-shaped supports,
to supply softness and smooth comfort with elastic support.
DESCRIPTION OF RELATED ART
[0002] In the light of the hectic pace of daily activities in our
modern society, if the mental stress cannot be appropriately
alleviated, it could lead to serious insomnia. It is for this
purpose that the selection of good bedding, the level of comfort of
bedding can have a critical effect on the quality of our sleep.
Since the human neck is left in suspension as soon as a person lies
down, a pillow is needed in order to provide a proper level of
support to maintain the neck at such a level as to ensure that a
person has a healthy sleep posture as well.
[0003] Nevertheless, it has been observed that the conventional
pillows after long term use, in the area where a person often lays
their head, a depression frequently can be found such as shown in
FIG. 1, in accordance with FIG. 2, of which the conventional
pillows at least comprises:
[0004] The main body of the pillow (10), which contains a filler
(101), the said filler (101) can be made of down feathers, silk or
memory foam; and
[0005] An external cover (20), which is used to wrap around the
exterior of the main body (10).
[0006] When conventional pillows are not in use, regardless of
which material is chosen as the filler (101), it should remain in a
fluffy state, and should be able to provide the level of support
needed by the person who lays his head on it. However, when a
person lays his head down on the body of the pillow (10) covered by
the external cover (20), if the content of the filler (101) is made
of down feathers or silk that would be compressed and shifted,
rather then displaced toward the areas where it is not compressed.
As shown in FIG. 2 that the compressed area of filler (101) is
thinner, relatively speaking, the area of filler that is not
compressed (101) has a higher density; as a result it easily
provokes the phenomena such as shifting and flattening. Even if the
filler (101) is made of memory foam after long-term use that it
cannot remain in its initial form. This causes the pillow to be
unable to provide close comfortable support between the users head
and the pillow. This means that for the user after sleeping on the
pillow for long periods of time, they may experience discomfort due
to muscle stiffness
[0007] A number of conventional pillows that are available in the
marketplace employ a filler (101) which is made of short chemical
fibers. In the production process, the aforementioned short
chemical fibers are cut into lengths of a few centimeters, that
they are easily broken down and separated. Hence, after long-term
use causing the performance features such as fluffiness, air
permeability and softness become inadequate. As a result, the
comfort of sleep is adversely affected.
[0008] In light of these facts, existing pillows have been
investigated and improved; with regards to this invention, it is
designed in order to improve these issues, after spending a
considerable amount of time on research, development and repeated
testing, this invention is disclosed.
