Patent Application
20170079280
The technical field relates to shoes package and storage boxes, and more particularly to a high-performance anti-fungal, anti-bacterial, insecticidal and deodorizing microcapsule and its application, and various kinds of chemical agents and carriers are added or attached onto the inner surface of the package box to achieve the anti-fungal, anti-bacterial, and deodorizing effects, and the chemical agents and carriers are made of constant-temperature sublimable volatile substances and film formers.
In early time, most shoes product packages taking costs into consideration were made of saturated monobasic aldehydes such as formaldehyde (formalin). Since these shoes product packages are considered as carcinogenic and teratogenic substances by World Health Organization and recognized as the sources of allergy as well as one of the most potential mutagens, therefore the using content is strictly restricted to a range≦(20 mg/kg) for infant products and a range≦(75mg/kg) for products in direct contact with skin. Under such limitation ranges, it is difficult to achieve the expected anti-fungal effect during the process of packaging and storing shoes products. Therefore, most manufacturers changed the raw material to dimethyl fumarate (DMF) which is the primary substance for the anti-fungal effect. However, DMF also causes damage to human health. According to clinical experiments, DMF may cause inflammation by the inhalation through esophagus and result in human intestinal and visceral corrosive damages, and after such substance is in contact with skin, DMF may cause contact dermatitis and pain such as itching, irritation, redness, and burn, and thus jeopardizing human health tremendously. Therefore, the European Product Safety Commission passed the decision of banning the use of dimethyl fumarate (DMF) on Jan. 29, 2009 by way of poll and requested for the approval of by the European Product Safety Commission. On Mar. 17, 2009, the European Product Safety Commission announced Directive 2009/251/EC of banning the use of DMF and specified the maximum limit of using DMF in a product to 0.1 mg/kg, and thereafter American Apparel and Footwear Association (AAFA) also announced the restricted substances list RSL Version 4 which includes the DMF banned by the European Product Safety Commission.
Under the strict control and use of formalin and DMF, it gives a headache to related manufacturers to prevent fungal attack to shoes products in the period after being packaged to the time being stored by consumers. In present markets, the substances added to the shoes products for preventing fungal growth are mainly divided into the following two types:
1. Desiccants mainly composed of silica gel, calcium chloride, magnesium chloride, aluminum oxide, molecular sieve, activated carbon, charcoal, or activated clay. These substances mainly attach water molecules on their structures through physical methods to create a dry environment in the limited space, such that fungi will not grow easily. However, such product has the following drawbacks: (A) This product cannot provide a long-term safe protection because the water content of only 8˜15% by weight is absorbed. (B) After saturation, factors including the ambient temperature and the self deliquescence may regain moisture and produce fungi and molds if the desiccant is not changed timely. (C) No air is allowed in the package, and thus desiccants are just applicable for closed package only. (D) There are concerns about the desiccant being eaten by children by mistake.
2. Anti-fungal tablet is mainly composed of natural mustard oil (commonly known as wasabi extract), but actually composed of “allyl isothiocyanate” (artificial mustard oil). The substance is a strong stimulating gas spread in a specific space and achieving the effect of preventing fungi or molds from growing easily by fumigation. Since the anti-fungal tablet has a strong stimulating volatile smell, it is used for shoes products only so far. However, this substance has several serious problems: (A) “Allyl isothiocyanate” is one of the top listed items in the “List of Hypertoxic Chemicals” (Rank 15th among more than 300 items). (B) The powerful toxicity of allyl isothiocyanate may harm animals and humans substantially. (C) The substance achieves the expected effect by the volatile stimulating gas through fumigation, so that if the package is unable to prevent air from entering, the fumigation time is very limited and thus failing to maintain a long-time protection. (D) The composition of “allyl isothiocyanate” fears humid air, so that the dryness in the storage environment, packaged content and package box may be maintained during use, so as to achieve the fumigation function. (E) The substance vaporized from “allyl isothiocyanate” is a yellow acidic gas which may yellow a white packaging material or oxidize (rust) a metal substance. (F) There are concerns about the anti-fungal tablet being eaten by children by mistake.
