Description
BACKGROUND OF THE INVENTION
[0001] The present invention is related to a slipper with hollow
sole, and more particularly to a slipper which can tenderly and
snugly attach to a user's sole. In addition, the slipper can
provide decorative visual effect.
[0002] Slippers are widely used in family life and leisure activity
such as dabbling. Slippers with more and more functions and more
and more beautiful appearance have been developed. The soles of the
conventional slippers are made from foam material, plastic or
rubber. With respect to the sole made from the foam material, the
sole is quite soft and lightweight. However, such sole tends to be
contaminated by dirt and soaked with water. Therefore, in fact, the
foam material is not an optimal material for the sole of a slipper.
With respect to the rubber sole, such sole is expensive and not so
soft as the foam material. A recently popular slipper has a sole
made by plastic injection molding. A PVC filament ring pad is
attached to the surface of the sole. The PVC filament ring pad
provides a good treading feeling. However, dirt tends to accumulate
in the PVC filament ring pad and is hard to clean up.
SUMMARY OF THE INVENTION
[0003] It is therefore a primary object of the present invention to
provide a slipper with hollow sole made by plastic blowing molding.
The plastic-made sole is dirtproof and lightweight.
[0004] It is a further object of the present invention to provide
the above slipper in which decorative fillings are additionally
filled into the hollow sole to achieve decorative effect and
enhance the appearance of the slipper.
[0005] According to the above objects, the slipper with hollow sole
of the present invention includes: a sole made by plastic blowing
molding as a flexible envelope, the envelope defining an internal
room, a working hole being formed on an edge of the sole; a clump
adhered to bottom face of the sole; and a detachable binder. The
sole is formed with at least one fixing hole in which at least one
end of the binder is detachably fixed. The fixing hole extends from
upper face to lower face of the sole.
[0006] The present invention can be best understood through the
following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Please refer to FIG. 1. The slipper with hollow sole of the
present invention includes a sole 1, a clump 2 and a detachable
binder 3.
[0016] The sole 1 has a toe section 12 and a heel section 13. The
sole 1 is made by plastic blowing molding as a flexible envelope
17. The envelope 17 defines an internal room 11 as shown in FIG. 6.
In this embodiment, the sole 1 can be transparent or
nontransparent.
[0017] The clump 2 is adhered to bottom face of the sole 1. A
bottom face 21 of the clump 2 in contact with the ground is formed
with stripes for enhancing friction.
[0018] In this embodiment, the binder 3 is fork-shaped and made
from rubber. The forked binder 3 has three end sections 31 fixed
with the sole 1. The sole 1 has at least three fixing holes 32 for
fixing the binder 3. The fixing holes 32 extend from upper face of
the sole 1 to lower face of the sole 1. A lower end of each fixing
hole 32 is enlarged. The end sections 31 of the binder 3 are fitted
through the fixing holes 32 and located in the enlarged lower ends
thereof as shown in FIG. 2.
[0019] The sole 1 is hollow so that the sole 1 is quite
lightweight. When a user wears the slippers on both feet, the sole
of the user will exert a pressure onto the sole 1 to resiliently
deform the sole 1 as shown in FIG. 3. After deformed, the sole 1
has a configuration adapted to the profile of the user's sole.
Therefore, the sole 1 will tenderly and snugly attach to the sole 4
of the user.
[0020] By means of the blowing mold, the surface of the sole 1 can
be made with wave stripes or figures as shown in FIG. 4. The wave
stripes make it easier for the hot gas of the sole 4 to escape.
Therefore, the soles of the user can keep cool and comfortable.
Also, the wave stripes provide some massaging effect.
[0021] Referring to FIG. 6, when making the sole 1 by plastic
blowing molding, a working hole 131 is left at rear end of the heel
section 13. A liquid filling 16 can be filled into the room 11 of
the sole 1 through the working hole 131 and then the working hole
131 is blocked with a plug 14. Accordingly, the sole 1 can provide
a cooling effect. In the case that the sole 1 is made from
transparent plastic material, a user can see the interior liquid
filling 16 through the transparent plastic material to have various
visual effects. Decorative pieces 18 such as bright chips can be
additionally filled into the sole 1 as shown in FIG. 5. When the
liquid filling 16 is disturbed, the decorative pieces 18 will float
along with the liquid filling 16 to enhance the appearance of the
slipper.
[0022] FIG. 7 shows a second embodiment of the present invention,
in which the binder 3A bridges over the sole 1A. The binder 3A is
composed of two symmetrical fixing sections 31A and an arch section
32A interconnected between the two fixing sections 31A. Two
symmetrical slots 17A are respectively formed between two sides of
bottom face of the sole 1A and the clump 2A. The two fixing
sections 31A of the binder 3A are fixedly adhered in the slots 17A
between the sole 1A and the clump 2A.
[0023] FIG. 8 shows a third embodiment of the present invention, in
which the binder 3B has an arch section and two sides of the arch
section respectively have several downward extending enlarged
insertion sections 32B arranged equal intervals. Several through
holes 121B are respectively formed on two sides of the sole 1B
corresponding to the insertion sections 32B. A lower end of each
through hole 121B is enlarged for receiving therein the insertion
section 32B. Accordingly, the insertion sections 32B can be fixed
between the sole 1B and the clump 2B.
[0024] The above embodiments are only used to illustrate the
present invention, not intended to limit the scope thereof. Many
modifications of the above embodiments can be made without
departing from the spirit of the present invention.
