Description

BACKGROUND OF THE INVENTION

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.

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

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.

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.

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.

The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
