Patent Application
20170367908
The present invention relates generally to diapers, and particularly to an ecofriendly diaper system.
Currently, there are several solutions for storing, cleaning and disposing children and adult diapers. Some of these solutions attempt to provide disposable diapers, but these solutions fail to meet the needs of the industry because of high cost, the significant and undesirable contribution to landfills, and introduction of harmful chemicals to the users and the environment. An estimated 27.4 billion disposable diapers are used in the US, resulting in approximately 3.4 million tons of waste added to landfills each year. Disposable diapers often contain hazardous chemicals such as Dioxin, Tributyl-tin (TBT), and sodium polyacrylate. Other solutions attempt to provide washable cloth diapers, but these solutions are similarly unable to meet the needs of the industry because of foul odor and unsightliness of the soiled diapers, the high cost of cleaning by third-party services, and the possibility of not having diapers on hand when needed.
It would be desirable to have a solution that provides a low-cost and ecofriendly diaper system for storing, cleaning, and re-using diapers at home. Furthermore, it would also be desirable to have a material composition that is absent of harmful chemicals. Therefore, there has been a very long-felt need in the industry for a diaper management solution that provides for storage and cleaning of diapers at home, absent any of the aforementioned deficiencies.
The present invention advantageously fills the aforementioned deficiencies by providing an ecofriendly diaper system, which provides a low-cost, environmentally friendly, and chemical-free solution for storing and cleaning soiled diapers at home. Ecofriendly is defined as having little, or no, harmful impact on the environment.
The present invention is an ecofriendly diaper system that is ecofriendly, and is capable of recycling soiled diapers at a low cost, without foul odor, without unsightliness, without harmful chemicals. The ecofriendly diaper system is comprised of a water-soluble diaper bag, which stores a soiled diaper, seals via a knot or heat, and can be stored and cleaned in a conventional manner at home. Preferably, the water-soluble diaper bag is made of a thin film of polyvinyl alcohol. Further, the polyvinyl alcohol film is manufactured to react with water at temperatures above the normal human body temperature, and optionally made with an opaque color. In an embodiment, the water-soluble bag is shaped long enough to permit sealing it via a knot. In a different embodiment, the water-soluble bag is sealed by heat. The sealed water-soluble bags containing soiled diapers are stored in a conventional household hamper, and cleaned using a conventional washer/dryer. The water-soluble diaper bags may be manufactured in different sizes to accommodate diapers of different of sizes.
The ecofriendly diaper system of the present invention optionally has a diaper container for storing and dispensing unused water-soluble diaper bags. This diaper container may have a moisture-proof lid to protect the unused water-soluble diaper bags in the diaper container. Further, the diaper container has an optional heating element to seal the water-soluble diaper bags containing soiled diapers. In the presence of a heating element, appropriate electrical safety measures are employed in compliance with the relevant safety and regulatory requirements. Further, either an ON/Off switch or an automated sensor is provided to heat and seal a water-soluble diaper bag when needed, absent the risk of overheating via a shut-off mechanism.
The water-soluble diaper bag is optionally manufactured with polyvinyl alcohol, an ecofriendly compound that has excellent film forming properties, is odorless and nontoxic, and has high tensile strength and flexibility. Further, the polyvinyl alcohol compound can be manufactured to dissolve in water at specific temperatures, such as one that is above the normal human body temperature, thus, avoiding accidental ruptures due to the moisture content of the soiled diapers. Still further, the polyvinyl alcohol compound may be manufactured in opaque and colorful finishes for aesthetic reasons and to hide the unsightliness of soiled diapers.
The conventional cloth or washable diapers are optionally externally coated by a thin film of moisture-proof material, such as plastic, to minimize leakage of the content through the walls of the diaper into the bag.
The present invention is unique when compared with other known systems and solutions, such as disposable or cloth diapers, in that it provides an ecofriendly diaper that does not contribute to landfills, does not contain any harmful chemicals, stores soiled diapers at home without foul odor or unsightliness, and can be washed in conventional household washer/dryer. The present invention is substantially more ecofriendly and cost effective compared to the currently used diaper solutions.
The present invention is superior to other systems and unique in that the overall architecture of the system is different from other known systems. More specifically, the present invention is unique due to the presence of: (1) a water-soluble diaper bag, which seals and stores soiled diapers at home without foul odor or unsightliness; (2) the ability to clean the soiled diapers in conventional household washer/dryer; (3) a container and dispenser for storing unused water-soluble diaper bags with a moisture-proof lid; (4) a heating element for sealing the water-soluble bags containing soiled diapers; (5) an ecofriendly system that does not contribute disposable diapers to landfills; (6) cost effective materials and processes; (8) water-soluble bags of different sizes, opacity, and colors; and (8) no harmful chemicals. The present invention fully recycles diapers in a convenient, safe, ecofriendly, and cost-effective manner.
Among other things, it is an object of the present invention to provide an ecofriendly diaper system that does not suffer from any of the problems or deficiencies associated with prior solutions.
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, which are intended to be read in conjunction with both this summary, the detailed description, and any preferred and/or embodiments specifically discussed or otherwise disclosed.

With reference to
The diaper container 300 optionally provides a pair of heat-sealing elements 340 for sealing a water-soluble diaper bag containing a soiled diaper along the heat-sealing zone 115. The heat-sealing elements 340 are mounted on the diaper container 305 and against the inside surface of a heating element lid 325 in a mating manner when the heating element lid 325 is closed. In the preferred embodiment of the present invention, the heating element lid 325 is pivotally attached to a surface of the diaper container 300 via heating element lid hinge 330 as shown in
The heat-sealing elements 340 are electrically powered to heat the elements and seal the water-soluble diaper bags containing diapers, using batteries or household electricity. In the presence of such heat-sealing feature, appropriate electrical safety measures are employed in compliance with the relevant safety and regulatory requirements. An ON/Off switch 335 activates the heating-sealing elements 340 long enough to seal a bag but not to overheat.
A thermal insulator 345 is positioned inside the diaper container 300 in between the heating sealing elements 340 and the storage space 305 to protect any unused diaper bags stored in the storage space. The thermal insulator is made of a commercially available thermal insulation material such as silicone, melamine Foam, polyimide foam, fiberglass, mineral wool, or polystyrene.
In its most complete version, the ecofriendly diaper system is made of the components illustrated in
In a different embodiment of the present invention, the outer surfaces of the conventional washable or cloth diaper 400 are externally coated by a thin film of moisture-proof material, such as a thin film of plastic, to prevent leakage of the content through the walls of the diaper.
