Scraper sponge

Abstract

A scraper sponge for cleaning and scraping away unwanted substances from an object or surface comprising a sponge body defining a first surface, first layer, second layer, third layer, second surface opposite the first surface, a continuous side surface around the perimeter; and the back of a scraper secured to the first layer opposite the first surface and the scraper defined by the first layer and an aperture through and approximately in the middle of the second layer, third layer and second surface of the sponge body. The entire surface area of the scraper, on it's front surface, is covered with pyramid shaped points extending outwardly in the direction of the second surface of the sponge body and is made level with the second surface of the sponge body when forces are applied to the first surface and subsequent back of scraper to manipulate the rigid scraper on a hard surface. The sponge body has three surfaces available for cleaning and scouring: the first surface, front scraper surface and second surface. The seamless second layer, third layer, third surface, and continuous side surface of the second and third layer are made of the same sponge-like cellulose material. As an alternative, the second layer, third layer, second surface, and the continuous side surface of the second and third layer are not made of the same material and the sponge body has at least four surfaces adapted for cleaning and scouring; the first surface, scraper front surface, the continuous side surface of layer two and the second surface.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to sponges and, more particularly, to scraper sponges made of natural and / or manmade materials adapted for cleaning and scraping a desired area.[0002]Sponges have been used for many years as a tool for cleaning cookware, utensils, kitchen and bathroom surfaces, automobile surfaces, windows, floors, furniture and a myriad of other objects and surfaces. Sponges are used in these applications in part because they are absorbent, reusable, lightweight, and easy to grasp and manipulate. However, a primary disadvantage of sponges is that by themselves, sponges are too soft and pliable to scrape away unwanted substances such as dirt, hardened oils or grease, mildew, and waxes or foods that stick and adhere to surfaces and reside in corners, grooves and crevices. To remedy this problem, abrasive layers have been added to sponges to enable users to scrape away substances. However, abrasive layers do not effectively allow users to ...

Benefits of technology

[0005]Sponges are used because they are absorbent, reusable, and lightweight. However, a primary disadvantage of sponges is that by themselves, sponges are too soft and pliable to scrape away unwanted substances such as dirt, hardened oils or grease, mildew, and waxes or foods that stick and adhere to surfaces and reside in corners, grooves and crevices. Abrasive layers do not effectively allow users to remove substances residing in tight corners, grooves and crevices because-neither the sponge nor the abrasive layer provide a rigid enough edge, to enable users to impart the requisite forces necessary for scraping and removing unwanted substances from the tight locations and from flat surfaces.

Problems solved by technology

However, a primary disadvantage of sponges is that by themselves, sponges are too soft and pliable to scrape away unwanted substances such as dirt, hardened oils or grease, mildew, and waxes or foods that stick and adhere to surfaces and reside in corners, grooves and crevices.

Abrasive layers do not effectively allow users to remove substances residing in tight corners, grooves and crevices because-neither the sponge nor the abrasive layer provide a rigid enough edge, to enable users to impart the requisite forces necessary for scraping and removing unwanted substances from the tight locations and from flat surfaces.

The attachment of the scraper portion to the sponge portion precludes use of the total sponge surface area, making the use of this device inconvenient and allowing the use of only one full surface of the sponge.

Also, use of the sponge in this manner can injure the hand as there is no support for the scraper in the soft sponge.

Moreover, the pliable nature of the sponge make grasping the scraper portion all the more difficult for simple and effective removal of unwanted materials.

In addition, the scraper is small and narrow which is not economical and requires excess scraping to cover a greater surface area.

While this device in an improvement over a sponge alone, its design is bulky, and makes access to tight areas difficult if not impossible.

The scraper portion of the device does not include a serrated edge, and moreover the application of the device precludes complete use of the sponge surface area.
