This patent specification relates to the field of cleaning devices. More specifically, this patent specification relates to a cleaning device having a plurality of inner cleaning layers that are revealed by removing outer cleaning layers.
Cleaning objects is an essential component of home life and professional life for many individuals. Typically, these individuals use cleaning instruments, such as cloths and sponges, to wipe and scrub surfaces and objects. Due to the nature of this use and with the use of cleaning products, the cleaning surfaces of these cleaning instruments can become worn to the point of decreasing their effectiveness. Users must then discard the entire cleaning instrument and replace it with another one. Not only is this time consuming and costly, but this leads to increased waste.
Therefore, a need exists for novel cleaning devices. A further need exists for novel cleaning devices which have a plurality of cleaning surfaces which can be individually revealed to provide the cleaning devices with renewed cleaning surfaces.
A renewable cleaning device is provided which has a plurality of cleaning surfaces which can be individually revealed to provide the cleaning devices with renewed cleaning surfaces.
In some embodiments, the device may include a body having two or more flexible material layers, and each flexible material layer may include a synthetic sponge material. The flexible material layers may be coupled together via compressing the flexible material layers together, and the flexible material layers may be removably coupled to each other so that they may be mechanically separated from each other, such as by peeling or pulling apart, without damaging the structural integrity of the flexible material layers.
In further embodiments, each flexible material layer may include and/or may be polyvinyl alcohol sponge.
In some embodiments, the device may include a body having two flexible material layers and an adhesive layer. The two flexible material layers may be coupled together via an adhesive, so that the adhesive layer removably couples the two flexible material layers together so that they may be separated without damaging the two flexible material layers.
In further embodiments, the device may include a plurality of flexible material layers and a plurality of adhesive layers. Each flexible material layer of the plurality of flexible material layers may be coupled to an adjacent flexible material layer via an adhesive layer of the plurality of adhesive layers so that the plurality of adhesive layers removably couple the plurality of flexible material layers together.
In further embodiments, each flexible material layer of the plurality of flexible material layers is made from a first material so that each flexible material layer is made from the same material, and each adhesive layer of the plurality of adhesive layers is made from a second material so that each adhesive layer is made from the same material.

In the case of air pore forming, there is no need to remove any additional material.
In preferred embodiments, the flexible material layers 21, 22, 23, 24, may be may be removably coupled to each other so that they may be mechanically separated from each other, such as by peeling or pulling apart, without damaging the structural integrity of the flexible material layers 21, 22, 23, 24, via compressing the flexible material layers 21, 22, 23, 24, together. In preferred embodiments, the flexible material layers 21, 22, 23, 24, may be removably coupled together so that each flexible material layer 21, 22, 23, 24, may be mechanically separated from an adjacent flexible material layer 21, 22, 23, 24, such as by peeling or pulling apart, without damaging the structural integrity of the flexible material layers 21, 22, 23, 24, via compressing the flexible material layers 21, 22, 23, 24, with a compression of between 100 grams to 1,000 kilograms per centimeter squared, optionally subjecting the flexible material layers 21, 22, 23, 24, to heat of between 60 to 260 degrees Celsius.
In some embodiments and as shown in
The device 100A, 100B, may comprise a plurality of flexible material layers 21, 22, 23, 24. In preferred embodiments, the device 100A, 100B, may comprise at least two flexible material layers 21, 22, 23, 24, such as two, three, four, five, six, seven, eight, nine, ten, etc., flexible material layers 21, 22, 23, 24.

A flexible material layer 21, 22, 23, 24, of the device 100A, 100B, may be made from or may comprise any flexible material which may be used for cleaning purposes. In some embodiments, one or more, such as each, flexible material layer 21, 22, 23, 24, of the plurality of flexible material layers 21, 22, 23, 24, may comprise a synthetic sponge material, such as which may be made of polyvinyl alcohol sponge, polyester sponge, polyurethane sponge, melamine foam, or synthetic expanded and foam materials. In some embodiments, one or more, such as each, flexible material layer 21, 22, 23, 24, of the plurality of flexible material layers 21, 22, 23, 24, may comprise a natural sponge material, such as animal fiber or sea sponges, vegetable cellulose sponge, or other naturally occurring sponge material. In some embodiments, one or more, such as each, flexible material layer 21, 22, 23, 24, of the plurality of flexible material layers 21, 22, 23, 24, may comprise a fabric cloth material.

Flexible material layers 21, 22, 23, 24, and therefore the body 11, may be configured in any size and shape. In preferred embodiments, flexible material layers 21, 22, 23, 24, may comprise a generally rectangular prism shape, optionally having rounded corners, so that when the flexible material layers 21, 22, 23, 24, are coupled together via the adhesive layers 41, 42, 43, the body 11 may comprise a generally rectangular prism shape, optionally having rounded corners, having a thickness defined by the thickness of the flexible material layers 21, 22, 23, 24, and the adhesive layers 41, 42, 43. In further embodiments, the flexible material layers 21, 22, 23, 24, and the adhesive layers 41, 42, 43, (and therefore the body 11) may comprise a cylindrical shape, a square prism shape, a triangular prism shape, or any other shape, including combinations of shapes. The thickness dimension of a flexible material layer 21, 22, 23, 24, may comprise its smallest dimension, while its length and width dimensions may comprise its two largest dimensions. For example, a flexible material layer 21, 22, 23, 24, having a three inch by four inch rectangular prism shape, may have a thickness dimension that may be less than fifty percent of its largest dimension, and more preferably less than ten percent of its largest dimension. Preferably, the thickness dimension of a flexible material layer 21, 22, 23, 24, may be between 0.0625 inches and 0.25 inches (1.58 millimeters and 6.35 millimeters).
In some embodiments, the device 100B may comprise one or more adhesive layers 41, 42, 43. In preferred embodiments, the device 100B may comprise at least two adhesive layers 41, 42, 43, such as two, three, four, five, six, seven, eight, nine, ten, etc., adhesive layers 41, 42, 43. In further preferred embodiments, the device 100B may comprise at least eleven adhesive layers 41, 42, 43, such as eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, or more adhesive layers 41, 42, 43. Adhesive layers 41, 42, 43, 23, may be configured in any size and shape. Preferably, an adhesive layer 41, 42, 43, may be shaped or applied to substantially cover (over 90 percent) of a major surface 21A, 21B, 22A, 22B, 23A, 23B, 24A, 24B, to which it is applied or adhered to.
An adhesive layer 41, 42, 43, may be made from or may comprise any flexible adhesive material which may be suitable for removably coupling two flexible material layers 21, 22, 23, 24, together and which may be flexible to allow the flexible material layers 21, 22, 23, 24, and therefore the body to be bent and flexed for use during cleaning, adsorbing, and rubbing tasks. In preferred embodiments, one or more, such as each, adhesive layer 41, 42, 43, may comprise a flexible waterproof adhesive material, such as described in the following paragraphs.
In some embodiments, a flexible adhesive material may comprise a hot melt adhesive. Hot melt adhesives are brought to liquid form with heat and can be used to coat entire surfaces before the adhesive cools into a solid polymer. Many industrial sectors appreciate them for their eco-friendliness, safety and shelf life. Different types of hot melt adhesives include EVA-based, APAO-based and those that are pressure-sensitive. Polyurethane hot melts are also available and may be used.
In some embodiments, a flexible adhesive material may comprise a reactive hot melt adhesive. Unlike non-reactive hot melt, reactive hot melt adhesives generate additional chemical bonds after the solidification process. This results in stronger adhesion once cured, expanded bonding as well as a higher resistance to moisture, heat and chemicals.
In some embodiments, a flexible adhesive material may comprise a thermosetting adhesive. Thermosetting adhesives are usually available in two-part forms. Resin and Hardener are mixed to obtain a desired setting time. The resin and hardener can be used in one-part form, however these aren't as common because they must be stored in low temperatures. Storing them in high temperatures can cause the desired reaction to occur prematurely, resulting in a much lower shelf life.
In some embodiments, a flexible adhesive material may comprise a pressure sensitive adhesive (PSA). Adhesives in this category are low modulus elastomers, meaning they do not require much pressure to deform and can be used on wet surfaces. They are quite durable for light load applications and are normally purchased as tapes or labels for non-structural applications. Pressure sensitive adhesives are usually based on an elastomer compounded with a suitable tackifier (e.g., a rosin ester). The elastomers can be based on acrylics, which can have sufficient tack on their own and do not require a tackifier. Styrene block copolymers (SBC), also called styrene copolymer adhesives and rubber-based adhesives, have good low-temperature flexibility, high elongation, and high heat resistance. They are frequently used in hot melt adhesive applications, where the composition retains tack even when solidified; however non-pressure-sensitive formulations are also used. They usually have A-B-A structure, with an elastic rubber segment between two rigid plastic endblocks. High-strength film formers as standalone, increase cohesion and viscosity as an additive. Water-resistant, soluble in some organic solvents; cross-linking improves solvent resistance. Resins associating with endblocks (cumarone-indene, α-methyl styrene, vinyl toluene, aromatic hydrocarbons, etc.) improve adhesion and alter viscosity. Resins associating to the midblocks (aliphatic olefins, rosin esters, polyterpenes, terpene phenolics) improve adhesion, processing and pressure-sensitive properties. Addition of plasticizers reduces cost, improves pressure-sensitive tack, decrease melt viscosity, decrease hardness, and improves low-temperature flexibility. The A-B-A structure promotes a phase separation of the polymer, binding together the endblocks, with the central elastic parts acting as cross-links; SBCs do not require additional cross-linking. Styrene-butadiene-styrene (SBS) is used in high-strength PSA applications, styrene-ethylene/butylene-styrene (SEBS) in low self-adhering non-woven applications, and styrene-ethylene/propylene (SEP) and styrene-isoprene-styrene (SIS) are used in low-viscosity high-tack PSA applications.
In some embodiments, a flexible adhesive material may comprise a contact adhesive. Contact adhesives are elastomeric and are applied to both items being bonded together. Once the solvent evaporates, the items are brought into direct contact. These types of adhesives are found in rubber cement or countertop laminates.
