Abstract

Claims (61)

1 . A scraping device for scraping and removing substances from an interior surface of a vessel, comprising:

a handle;

an elbow joint;

a semi-circular hook;

a ribbed edge;

a scraping tip; and

a substance collection reservoir;

wherein the substance collection reservoir includes a physical chamber built into the scraping tip;

wherein the substance collection reservoir extends from an end of the scraping tip into at least 1% of a length of the semi-circular hook;

wherein the handle is connected to the semi-circular hook by the elbow joint;

wherein the semi-circular hook is operable to conform to the interior surface of the vessel;

wherein the ribbed edge is formed along an exterior surface of the semi-circular hook and provides a flush fit between the scraping device and the interior surface of the vessel;

wherein the ribbed edge is formed along the outside perimeter of the semi-circular hook in its entirety and acts as a scrapping edge to scrape the interior of the vessel;

wherein the semi-circular hook has a handle end and a distal end;

wherein the scraping tip is located at the distal end of the semi-circular hook and extends away from the distal end of the semi-circular hook;

wherein the vessel includes an opening and a neck; and

wherein rotation of the scraping device causes the ribbed edge to scrape a substance adhered to the interior side surface of the vessel, thereby removing the substance from the interior side surface of the vessel.

2 . The scraping device of claim 1 , wherein the ribbed edge includes serrations to increase applied pressure at each point of contact between the serrations and the interior surface of the vessel.

3 . The scraping device of claim 1 , wherein the ribbed edge includes bristles for removing substances from the interior surface of the vessel.

4 . The scraping device of claim 1 , wherein the ribbed edge includes a blade for removing substances from the interior surface of the vessel.

5 . A scraping device for scraping and removing substances off an interior surface of a laboratory vessel, comprising:

a handle;

an elbow joint;

a semi-circular hook;

a ribbed edge;

a scraping tip; and

a substance collection reservoir;

wherein the substance collection reservoir includes a physical chamber built into the scraping tip;

wherein the substance collection reservoir extends from an end of the scraping tip into at least 1% of a length of the semi-circular hook;

wherein the handle is connected to the semi-circular hook by the elbow joint;

wherein the semi-circular hook is operable to bend and conform to the interior surface of the laboratory vessel;

wherein the ribbed edge provides a flush fit between the scraping device and the interior surface of the laboratory vessel;

wherein the ribbed edge is operable to scrape substances that have adhered to the interior surface of the laboratory vessel;

wherein the laboratory vessel includes an opening, a body and a neck;

wherein a width of the body is wider than a width of the opening and/or neck;

wherein the semi-circular hook has a handle end and a distal end; and

wherein the scraping tip is connected to the distal end of the semi-circular hook and extends away from the distal end of the semi-circular hook.

6 . The scraping device of claim 5 , wherein the ribbed edge includes serrations to increase applied pressure at each point of contact between the serrations and the interior surface of the laboratory vessel.

7 . The scraping device of claim 5 , wherein the ribbed edge includes bristles for removing substances from the interior surface of the laboratory vessel.

8 . The scraping device of claim 5 , wherein the ribbed edge includes a blade for removing substances from the interior surface of the laboratory vessel.

9 . The scraping device of claim 5 , wherein the scraping device includes two hooks on opposite ends of the scraping device connected by the handle.

10 . A scraping device for scraping and removing substances off an interior surface of a laboratory vessel, comprising:

a handle;

finger grips;

an elbow joint;

a semi-circular hook;

a ribbed edge; and

a scraping tip;

wherein the handle is connected to the semi-circular hook by the elbow joint;

wherein the finger grips are indents within the handle;

wherein the semi-circular hook is operable to bend and conform to the interior surface of the laboratory vessel;

wherein the ribbed edge provides a flush fit between the scraping device and the interior surface of the laboratory vessel;

wherein the ribbed edge is operable to scrape substances that have adhered to the interior surface of the laboratory vessel;

wherein the laboratory vessel includes an opening, a body and a neck;

wherein a width of the body is wider than a width of the opening and/or neck;

wherein the semi-circular hook has a handle end and a distal end; and

wherein the scraping tip is connected to the distal end of the semi-circular hook and extends away from the distal end of the semi-circular hook.

11 . The scraping device of claim 10 , wherein the ribbed edge includes serrations to increase applied pressure at each point of contact between the serrations and the interior surface of the laboratory vessel.

12 . The scraping device of claim 10 , wherein the ribbed edge includes bristles for removing substances from the interior surface of the laboratory vessel.

13 . The scraping device of claim 10 , wherein the ribbed edge includes a blade for removing substances from the interior surface of the laboratory vessel.

14 . The scraping device of claim 10 , wherein the handle has a left and right side, wherein the finger grips are located on both the left and right side of the handle.
