Conventional devices for cutting sheet material and especially food wrap typically involve the permanent attachment of a cutting blade to a specialized container, see for example U.S. Pat. No. 5,984,158 to Frank which relates to a cutting blade for an aluminum foil dispenser. In such conventional devices, the cutting blade is typically attached next to, or over, a wall of the specialized container that is narrow, typically less than ⅛ inch (0.3 centimeters), see for example U.S. Pat. No. 6,491,198 to Frank, U.S. Pat. No. 2,771,186 to Burbank, U.S. Pat. No. 3,567,087 to Schramm and U.S. Pat. No. 5,947,360 to Frank.
However, none of these devices provide for the attachment of the device to a general purpose container such as a drawer which have wider walls, typically ¼ inch (0.6 centimeters) or more, and which can be used to store other objects. Further, these devices are generally designed for permanent attachment to the specialized container.
One aspect of the present invention is to provide a device for cutting food wrap or other sheet material which can be removably mounted on or in a general purpose storage container such as a drawer. In one embodiment, this device is concealed when the drawer is in a closed position.
Another aspect of the present invention is to provide a device for cutting sheet material having: (1) a mounting portion for attachment to a wall of a general purpose storage container, the general purpose storage container having a holder for the sheet material, and storage space for objects other than the sheet material; and (2) a cutting portion attached to the mounting portion along a first side and having a cutting edge along a second side. In addition, the general purpose storage container can be a drawer and the drawer can be mounted in a cabinet. Also, the drawer can include means for moving the drawer from a first position where at least a portion of the cutting portion is accessible from outside the cabinet and a second position where the cutting portion is not accessible from outside the cabinet.
Further aspects of the present invention include: (1) the holder being a bottom surface of the general purpose storage container; (2) the mounting portion being removably attached to the wall; and/or (3) the mounting portion being a channel having a base and two arms, the channel being placed over a top of the wall such that the base of the channel is adjacent to the top of the wall and the arms of the channel are adjacent to the inside surface and outside surface of the wall respectively. Also, the base and arms of the channel can be generally flat.
Yet another aspect of the present invention provides: (1) that the second side of the cutting portion is positioned parallel to, and proximate to, the plane defined by the outside surface of the wall; and/or (2) that the cutting edge includes a series of teeth for cutting the sheet material. Also, the corner between a ridge of a tooth and the inside wall of the tooth can be rounded and/or a corner between a ridge of a tooth and the outside wall of the tooth can form an angle of about 90 degrees.
A further aspect of the present invention provides a system for cutting sheet material having: (1) a drawer having general storage space for holding a sheet material supply and at least one other object; and (2) a cutter having a mounting portion and a cutting portion, the mounting portion providing means for attaching the cutter to a wall of the drawer.
Another aspect of the present invention is to provide a method for cutting sheet material in which a user: (1) opens a drawer having a cutter on a wall of the drawer; (2) pulls sheet material from a holder in the drawer such that the sheet material extends across a cutting edge of the cutter; (3) applies stress to the sheet material, such that a portion of the sheet material presses against the cutting edge of the cutter; (4) severs a portion of the sheet material from the sheet material along the portion of the sheet material pressing against the cutting edge; (5) removes the severed portion for use; and/or (6) closes the drawer. In addition, the method can include: (1) attaching a mounting portion of the cutter to the wall; and/or (2) detaching a mounting portion of the cutter from the wall to remove the cutter.
The mounting portion 12 in this embodiment is a channel defined by two side arms or plates 16, 18 and a base or top plate 20 defining a rectangular cross-section. However, the mounting portion 12 can have other shapes, for example a square, curved or circular cross section. Also, other shapes for the mounting portion 12 such as spherical, oblong, or free form are also possible.
In this embodiment, the length of the device 10, that is along the direction of the cutting edge 14, is 13 inches (33.0 centimeters), the inside width, that is across the base 20 is 12/16 inches (1.9 centimeters), the inside depth across the first arm 16 is 14/16 inches (2.2 centimeters) and the inside depth across the second arm is 15/16 inches (2.4 centimeters). The plates 16, 18, and 20 in this embodiment are each ⅛ inches (0.3 centimeters) thick.
This embodiment employs dimensions for a typical kitchen drawer and a typicial food wrap roll, but any dimensions which allow for the removable attachment of the device 10 to the wall 42 of a general purpose storage container 40 can be used. Also, the height of the cutting portion 14 is selected to allow enough clearance for a typical drawer to be moved normally from open to closed positions with respect to a cabinet. Also, if the dimensions of the channel are too large for a particular container, shims can be used between the arms 16, 18 and the respective wall 42 surface to keep the device 10 in place.
The cutting portion 14 in this embodiment has a first side 22 which connects to the mounting portion 12 and a second side 24 which extends away from the mounting portion 12. This second side 24 is configured with a cutting edge 26. The cutting edge 26 in this embodiment is serrated, that is formed as a plurality of cutting teeth 28 and are configured to easily guide and tear off selected portions of the sheet material. In this embodiment, each tooth is 3/16 inches (0.5 centimeters) in height and the cutting portion is ⅛ inches (0.3 centimeters) thick.
In this embodiment, the cutting portion 14 is attached to the mounting portion 12 such that the cutting edge 26 extends above and aligns with the outside surface 48 of the wall 42. By aligning with the outside surface 48 of the wall 42, after a selected piece 62 of the sheet material 60 is torn away, the remaining edge of the sheet material remains frictionally connected to the cutting edge 26 along the tear and a portion of the remaining sheet material is also frictionally connected to the inside edge 66 between the base 20 and the first arm 16. By having these two frictional connections, the remaining sheet material 60 is held from falling back into drawer 40. In this way, the sheet material 60 can be conveniently grasped from above the wall 42 for selecting another piece of sheet material to sever without having to reach into the drawer 40. By maximizing the distance between the cutting edge 26 and the inside edge 66, the angle of the frictionally attached sheet material is lower, and the sheet material is more likely to remain frictionally attached to the device 10 for subsequent use.
Among the distinguishable features of the present invention is an inside drawer mounted apparatus having one or more pieces which are removable, dimensions for attachment to a wide, that is greater than ⅛ inch (0.3 centimeters) wall, and/or the ability to be concealed when the drawer is in the closed position.
While the device may be used in any application involving sheet materials, in one embodiment the sheet material 60 is food wrap, such as for example, plastic wrap, waxed paper, aluminum foil wrap, freezer paper, and parchment paper. These sheet material examples are not intended to limit the scope of the invention.
The present invention has been described by way of exemplary embodiments to which it is not limited. Variations and modifications will occur to those skilled in the art without departing from the scope of the present invention as recited in the appended claims and equivalents thereof.
This application claims the benefit of U.S. Provisional Application No. 61/213,227 filed May 19, 2009.
