Description

Technical Field

[0001] The present invention relates to a cleaning sponge having an inner capsule containing soap, and more specifically, to the dimensions of the holes in the capsule.

Background Art

[0002] Many people use a bathing sponge, for example, to wash dishes, and a cleaning sponge to clean and wash various accessories. It is known that the inventor has prior art regarding a cleaning sponge containing soap based on two methods. The first method is a sponge containing one solid soap such that when the soap comes into contact with water, it dissolves and soap bubbles are formed on the sponge. This method is inefficient, and there is a problem because the solid soap does not actually dissolve upon contact with water, but rather requires rubbing the solid soap, which is not possible because the solid soap is hidden inside the sponge. The second method is a sponge containing a relatively flexible capsule containing liquid soap that flows from inside the capsule into the sponge through small holes in the capsule. In this case, when the sponge is wrung, the capsule is actually wrung, causing the liquid soap to flow from the inner capsule into the sponge. The flow of liquid soap from the capsule into the sponge is not controlled, and even if the sponge is already full of bubbles and saturated with soap, the user's hand causes the liquid soap to continue to flow from the capsule into the sponge due to the pressure applied to the sponge during use, so this method is not perfect.

[0003] The present invention operates according to the principle of the second method described above, but provides an improved sponge having capsules that introduce new devices to solve problems specific to such sponges.

DETAILED DESCRIPTION OF THE INVENTION

[0005] The main object of the present invention is to provide a cleaning sponge having an inner capsule containing dishwashing soap paste such that when pressure is applied to the sponge by the user's hand during use, the soap flows out of the capsule in a controlled manner, and to provide the above-described sponge such that squeezing the sponge intentionally mainly leads to the flow of soap into the sponge.

[0006] The present invention refers to a sponge (1) having an inner capsule (2) containing dishwashing soap paste (3). FIG. 1 is a schematic top view of the capsule (2). FIG. 2 shows a cross-section of the sponge (1) and the inner capsule (2) having dishwashing soap paste (3). FIG. 3 shows a sponge (2) having an inner capsule (2) containing squeezed soap (3).

[0007] The sponge (1) may be one of various existing sponges, such as a sponge designed for dishwashing, a bath sponge, and various sponges for various uses. For the sake of brevity, the term "cleaning sponge" hereinafter and in the claims refers to all types of such sponges for the various above-described purposes. The sponge (1) has a generally flat rectangular cubic shape with a relatively wide upper surface (11), a wide bottom surface (12), and two narrow longitudinal side surfaces. The terms upper surface and bottom surface refer only to the larger and wider sides of the cleaning sponge (1) as shown in the drawings, whereas in reality, none of the side surfaces of the sponge (1) and the capsule (2) are shown as being upper surfaces. The cleaning sponge (1) can be made from an outer refined pad coating layer (6) and an inner sponge layer (6).

[0008] The inner capsule (2) is actually a closed packet having from six to eight holes (4) through which the dishwashing soap paste (3) flows from the capsule (2) into the sponge (1). The inner capsule (2) is of course smaller than the sponge (1). The capsule (2) is made of a material that is prone to wringing so that when the capsule is wrung, soap flows out through the holes in the capsule. Any material that can be wrung by an external force can be used to manufacture the capsule (2), although the capsule may be made of rubber or silicone. Thus, for example, materials such as those used to manufacture the inner tube of a bicycle tire can be used to manufacture the capsule or simply a plastic material or nylon material.

[0009] The capsule (2) preferably has a general shape of a flat rectangular cube that conforms to the outer shape of the sponge. The capsule (2) has a relatively wide upper surface (21) and a wide bottom surface (22) (not shown in the figure). The terms upper surface and bottom surface refer only to the larger and wider sides of the capsule (2), whereas in fact none of the sides of the sponge (1) and the capsule (2) are shown as being the upper surface. It is of course recommended that the capsule be made from a single integral part.

[0010] Holes (4) in the inner capsule (2): The inner capsule (2) contains from six to eight holes (4). The main new idea of the present invention is that there are from six to eight holes in the wide upper surface of the capsule and from six to eight holes in the wide bottom surface, and the size of each hole (4) is between 0.2 and 0.4 microns. Thus, when pressure is applied to the sponge (1) and thereby to the capsule (2), based on the fact that the viscosity of the dishwashing soap paste is from 10 3 to 10×10 3 cPa-s, there is no overflow of soap from the capsule through these holes (4) into the sponge. This combination of the viscosity of the soap (3) and the number and size of the holes (4) ensures the desired flow of soap from the capsule (2) into the sponge (1).

[0011] Incidental pressure on the sponge: When the user wrings the sponge, a pressure perpendicular to the wide side of the sponge (and the capsule) is applied - the pressure is naturally applied during sponge use, and then the sponge (1) itself presses against the wide sides (21)(22) of the capsule (2), and the sponge actually presses the hole (4) downward, preventing any overflow of soap from the capsule. Intentional pressure on the sponge: When the user wrings the sponge, a horizontal pressure is applied to the narrow side of the capsule, and the pressure is not naturally applied during sponge use, and then the hole (4) allows the soap to flow out of the capsule. Therefore, the user can control the flow of soap from the capsule into the sponge well and effectively.

[0012] The present invention has been described in connection with what is considered to be the most practical and preferred embodiments, but it is to be understood that the invention is not limited to the disclosed embodiments, but is intended to cover various configurations included within the spirit and scope of the broadest interpretation and to embrace all such modifications and equivalent configurations.

[0013] The capsule (2) can be made from various malleable materials. One such material is a nylon bag that can function as the capsule (2) required for the product that is the subject of the present invention. The inventor recommends that the nylon bag be 0.25 mm thick, although nylon bags (2) of various thicknesses can be used. The nylon bag (2) used needs to be perforated as described in the present application and needs to have between 6 and 8 holes (4) on each side. The diameter of such holes (4) needs to be between 0.2 and 0.4 microns. When the sponge (1) contains the capsule (2) made from the above-described nylon bag having the above-described thickness and the above-described diameter of the holes (4), no (substantial) flow of soap from the capsule (2) occurs by the application of normal pressure, that is, for example, the pressure applied by the average use of the sponge (1) when using the sponge (1) for washing dishes. However, when a more strongly intentional pressure is applied to the sponge (1) containing the nylon bag capsule (2), the soap flows from the capsule (2), enabling the effective and good use of the sponge (1).

[0014] The inventive part of the present invention is a combination of three things, namely (a) the specific viscosity of the soap, (b) the exact amount of holes, (c) the specific diameter of the holes, and (d) the number of holes on the upper surface being the same as that on the bottom surface in order to enable the efficient diffusion and dispersion of the soap inside the washing sponge. This combination provides good results, means, and the desired flow and control of the flow of soap from the inner capsule to both sides. If the viscosity of the soap, or the specific diameter or the exact number of holes, or the position of the holes is changed, the flow is not controlled, and any constriction of the sponge means that either a lot of flow is generated or it is difficult to obtain flow, and it may be one-sided only.
