Claims
1-8. (canceled)
9. A pillow comprising: an air permeable pillowcase having an
inside receiving space, the pillowcase being made of a transparent
material and provided with a plurality of apertures formed therein;
a plurality of resilient blocks formed of a deformable foam
material, the blocks being disposed within the inside receiving
space and defining a spacing therebetween; and whereby when the
head of a user is placed on the pillow and subjected to movement,
the pillow conforms to the changing position of the head through
deformation of the resilient blocks and provides comfortable
support for the user during sleep.
10. The pillow of claim 9, wherein the shape of each resilient
block is selected from the group consisting of spherical,
rectangular, columnar and rod-like.
11. The pillow of claim 9, wherein the resilient blocks are of
different shapes.
12. The pillow of claim 9, wherein the resilient blocks are of
different colors.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to bedclothes, and
more particularly to a pillow.
[0003] 2. Description of the Related Art
[0004] People are becoming more aware of the importance of the
quality of sleep, so they are more selective in choosing their
bedding, especially pillows. Because pillows determine whether
people sleep well or not, most people demand their pillows to be
comfortable, air-permeable and, above all, to conform to their head
shapes. However, everyone has an individual head shape that is more
or less different from another, so it is not easy to select a
pillow suitable for everyone.
[0005] Recently, many manufacturers in this field have developed
related products, which provide comfort, air-permeability, and
ergonomics. For example, pillows that are integrally formed of foam
material, such as latex, are commonly called space pillows,
ergonomic pillows, or memory pillows which conform to the human
curvature from the neck to the head and are air-permeable and
supportive to enable the user to feel comfortable.
[0006] The latex pillows are generally manufactured by injection
molding with various moulds of different shapes and sizes to
provide diversified shapes and sizes for children and adults.
However, many different moulds are required to manufacture the
pillows, so the production cost is relatively high.
[0007] Further, the conventional latex pillow has limited
deformability, so that the pillow does not completely conform to
the user's head curve when the head of the user is placed on the
pillow. Moreover, if the user turns back and forth on the bed while
sleeping, the conventional latex pillow will not effectively deform
to accommodate this motion.
[0008] In addition, the air-permeability of the material that the
pillow is made deeply affects the quality of the pillow. If the
material is not air-permeable, the user will easily feel tired and
sleep badly. Hence, the user must pay much attention while
selecting suitable pillows.
SUMMARY OF THE INVENTION
[0009] The primary objective of the present invention is to provide
an improved pillow that has low production cost, is highly
deformable to accommodate different head shapes, and prevents the
user from feeling muggy and providing comfort during sleeping.
[0010] The foregoing objective of the present invention is attained
by the improved pillow that includes a pillowcase having a
receiving space inside and a plurality of resilient blocks disposed
inside the receiving space. The resilient blocks are made of a foam
material, such as latex.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 is a perspective view of a first preferred embodiment
of the present invention; and
[0012] FIG. 2 is a perspective view of a second preferred
embodiment of the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0013] Referring to FIG. 1, a pillow 10 constructed according to a
first preferred embodiment of the present invention includes a
pillowcase 20 and a plurality of resilient blocks 30.
[0014] The pillowcase 20 is made of an air-permeable and
ventilative cloth, and includes a receiving space 21 inside.
[0015] Each of the resilient blocks 30 is a small ball made of an
injection molded foam material, such as latex, and is disposed
inside the receiving space 21 and securely encapsulated by the
pillowcase 20. The pillowcase 20 has a zipper to securely hold the
resilient blocks 30 inside the pillowcase 20. Alternatively, the
pillowcase 20 may have an opening to securely hold the resilient
blocks 30 inside the pillowcase 20 by seaming the opening. Spacing
31 is formed between the resilient blocks 30.
[0016] When the head of the user is placed on the pillow 10, the
resilient blocks 30 of the pillowcase 20 are squeezed and deformed
and the spacing 31 is also deformed to further cause some of the
resilient blocks 30 positioned under the head and the neck to
slightly move towards bilateral sides of the pillowcase, such that
the pillow 10 can conform to fit the head of the user. Further,
when the user sleeps and turns back and forth to change the angle
at which the head lies on the pillow 10, the pillow 10 is
correspondingly deformed. In otherwords, the interrelated positions
among the resilient blocks 30 change according to the user's
sleeping motion and provide accommodating support for the user's
head and neck, thereby further enabling the user to sleep more
comfortably.
[0017] Further, the spacing 31 ventilates the air inside the
receiving space 21 to reduce the temperature and humidity inside
the pillow 10, such that the user feels quite comfortable while
sleeping.
[0018] More, it is easy to reduce the production cost by the
manufacturers producing a great number of the resilient blocks 30
and putting different numbers of the resilient blocks 30 into
pillowcases 20 of different sizes to produce pillows of different
sizes.
[0019] The resilient blocks 30 of the present invention are not
limited in shape and appearance to provide resilient support.
[0020] Referring to FIG. 2, the pillow 40 constructed according to
a second preferred embodiment of the present invention is a pillow
for children and is different from the first preferred embodiment
in that the pillowcase 41 is made of a transparent plastic material
having a plurality of apertures 42, and a plurality of resilient
blocks 43 of various shapes and colors disposed inside the
pillowcase 41. The resilient blocks 43 can be, for example,
rectangular, long-pillared, moon-shaped, or any shape attractive to
children.
[0021] In addition, the resilient blocks used in the pillow of the
present invention can also be soaked in diversified fragrant
liquids that tranquilize the user and further help the user to
sleep well.
