Description

Sole and environmental slippers with the sole

The invention relates to a sole and slippers, in particular to a sole made of environmentally friendly materials and an environmentally friendly slippers with the sole.

Slippers are a type of shoe with only ears on the toe portion. Because they are very convenient to wear and take off, they are widely used. Most structures of general slippers are made of polyethylene vinyl acetate (EVA), polyethylene (PE), polypropylene (PP), polyurethane (PU), thermoplastic polyurethane elastomer rubber (TPU), polyvinyl chloride (PVC) or each Although made of similar plastic materials, it has the advantages of waterproof, durable, lightweight, low cost, etc., but these materials are not easily decomposed in the natural environment, and a large amount of use will cause a considerable burden on the natural environment.

Therefore, one of the objects of the present invention is to provide a shoe sole that can solve the aforementioned problems.

Therefore, in some embodiments, the sole of the present invention includes a main body layer and a wear layer. The body layer includes a top surface and a bottom surface on opposite sides, and the composition includes cork. The wear layer is disposed on the bottom surface of the main body layer, and the composition includes raw rubber that has not been vulcanized.

In some embodiments, the composition of the main body layer further comprises coffee material mixed with the cork material.

In some embodiments, the sole further includes a fiber woven layer, the fiber woven layer is disposed on the top surface of the main body layer, and the composition of the fiber woven layer includes natural fibers.

In some embodiments, the composition of the fiber woven layer includes at least one of cotton, hemp, natural silk, and natural leather.

In some embodiments, the thickness of the body layer is between 5 mm and 10 mm.

In some embodiments, the thickness of the wear-resistant layer is between 3 mm and 10 mm.

Another object of the present invention is to provide an environmentally friendly slippers.

Therefore, in some embodiments, the environmentally friendly slippers of the present invention include the sole as described above, and a shoe ear disposed on the top side of the sole.

The invention has at least the following effects: the main body layer, the wear-resistant layer and the fiber woven layer of the sole are made of environmentally friendly materials that can be naturally decomposed in the natural environment or easily decomposed by artificial means, which is not only harmless to the human body, but also damaged After it is unavailable, it can be gradually decomposed after a period of time without burdening the natural environment. In addition, in the embodiment in which the main body layer contains a coffee material, based on the characteristic that the coffee material can deodorize, it is possible to prevent the environmentally friendly slippers from generating an odor after long-term wearing.

1 and 2, it is an embodiment of the environmentally friendly slippers 1 of the present invention. In this embodiment, the environmentally friendly slippers 1 include a sole 2 and an insole 3 disposed on the top side of the sole 2, and a herringbone clip is used Foot slippers are described as an example, but the environmentally friendly slippers 1 can be any type of slippers, and are not limited to specific embodiments.

The sole 2 includes a main body layer 21, a wear layer 22 and a fiber woven layer 23.

The main body layer 21 of the sole 2 has a top surface 211 and a bottom surface 212 located on opposite sides. In one embodiment, the composition of the main body layer 21 includes cork, which is mainly processed from cork to form a structure suitable for the sole 2 The size of the production. Among them, the above-mentioned cork material can be obtained by crushing the remaining scraps in the process of producing cork stoppers, but not limited to the source of the material. In another embodiment, the main body layer 21 can also be made of cork material mixed with coffee material (such as coffee grounds) and an adhesive, and then prepared by hot pressing. Adding the coffee material can penetrate the fragrance and deodorization characteristics of the coffee material To allow users to use the environmentally friendly slippers 1 for a long time, it is not easy to produce odor, wherein the preferred weight percentage of the cork material is 45% ~ 55%, the preferred weight percentage of the coffee material is 5% ~ 15%, the The preferred weight percentage of the adhesive is less than 45%, and the preferred thickness of the body layer 21 is between 5 mm and 10 mm. Within this implementation range, the body layer 21 can have good structural strength and The deodorizing effect, however, can be adjusted as needed in the implementation, and is not limited to these implementation ranges. In addition, in this embodiment, the adhesive is preferably selected from the group consisting of viscose, UV-curing adhesive, or the foregoing combination. The viscose contains a polymer, and the polymer is selected from polyurethane, urea formaldehyde resin, and polyvinyl acetate. , Polyvinyl alcohol, polylactic acid, melamine-formaldehyde resin, melamine-urea-formaldehyde co-condensation resin, phenolic resin, resorcinol-formaldehyde resin, epoxy resin, or a combination of the foregoing. In this way, the main body layer 21 Coffee materials are all environmentally friendly materials, and the adhesive is also easy to decompose materials, which is conducive to achieving the effect of environmental protection.

The wear layer 22 of the sole 2 is disposed on the bottom surface 212 of the main body layer 21, and the composition includes raw rubber that has not been vulcanized. The vulcanization process will convert the raw rubber from a linear macromolecule to a three-dimensional network. Although the mature rubber can improve the strength and toughness of the rubber and is easier to form, it will also cause the rubber to be difficult to decompose. Therefore, in this embodiment, the composition of the wear layer 22 is made of raw rubber, which is an environmentally friendly material that is more easily decomposed, and Compared with the main body layer 21, which has better strength and hardness, it is suitable for manufacturing the wear-resistant layer 22 which is easier to wear. In addition, based on structural strength and wear requirements, the preferred thickness of the wear-resistant layer 22 is, for example, between 3 mm and 10 mm, but not limited to this implementation range.

The fiber woven layer 23 of the sole 2 is disposed on the top surface 211 of the main body layer 21, and its composition may include natural fiber materials such as cotton, hemp, natural silk, natural leather, etc., which can improve the comfort of wearing the environmentally friendly slippers 1 It can also strengthen the toughness of the top side of the main body layer 21, so that the main body layer 21 is not easy to crack and damage. However, according to actual needs, the sole 2 can also omit the arrangement of the fiber woven layer 23, that is, the sole 2 can also be provided with only the main body layer 21 and the wear layer 22.

In summary, the main body layer 21, the wear layer 22, and the fiber woven layer 23 of the sole 2 of the environmentally friendly slippers 1 of the present invention are made of environmentally friendly materials that can be naturally decomposed in the natural environment or easily decomposed by artificial means. The human body is harmless, and after being damaged and unusable, it can be gradually decomposed after a period of time, which will not cause a burden on the natural environment and meet the requirements of environmental protection. In addition, in the embodiment in which the main body layer 21 includes a coffee material, based on the deodorizing property of the coffee material, it is possible to prevent the environmentally friendly slippers 1 from generating an odor after long-term wearing. Therefore, the environmentally friendly slippers 1 of the present invention can indeed achieve the purpose of the invention.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still classified as This invention covers the patent.
