BACKGROUND OF INVENTION
The present invention relates to a cookware article, and in particular to a handle for cookware, and an article of cookware deploying such a handle.
Cookware handles commonly have holes at the end for receiving hooks or pegs for vertically hanging in a kitchen. Hollow handles are preferred for their lighter weight, as well as lower conductivity of heat, with respect to solid metal handles. As the hollow handle also dissipates heat, is provides the user with greater latitude to directly grasp the handle when cookware article is used on a stove top for a generally reasonable period of time. Hollow handles can also be relatively large for easy and secure gripping, but remain light in weight so the pan is not tipped over.
However, providing a hanging hole in a hollow handle presents some problem and complexity in its design and manufacturing, as it is desirable to prevent water and other materials from entering the hollow handle and flowing toward the flange where it would be heated and possibly produce steam. Thus, this hanging hole is preferably a pipe that extends downward through the open cavity of the handle to seal it, or in fact a solid plug at the end of the cookware with a simple bore through it. The former approach of providing a sealed pipe through the hollow portion is more complex to manufacture than a solid plug. However, the solid plug adds weight, in contradiction to the otherwise beneficial attribute of a hollow handle.
It is therefore a first object of the present invention to provide a generally hollow handle with a hanging mount that is simpler to manufacture without adding significant weight.
It is a further object of the invention to provide a hollow handle with a hanging mount that is unlikely to collect or accumulate debris.

DETAILED DESCRIPTION
Referring to FIGS. 1A through 4B, wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved cookware article, generally denominated 100 herein
In accordance with the present invention, the cookware article 100 has a vessel portion capable of retaining fluid 110 and a hollow handle 120 that has three sections, the first of which is a flange section 130 that is generally solid for attachment to the sidewall of a pot, pan or other cooking vessel 110. The flange section 130 typically is winged shaped with respect to the hollow handle portion 120 that extends in the generally orthogonal direction therefrom, and typically has 2 or more mounting or rivets holes. Next, a hollow sealed tubular grip portion 140 is attached to the terminal portion of the flange section 130 distal from the vessel 110. The third portion of the hollow handle 120 is a terminal section 150 that is plugged at the end opposite the connection to the grip portion 140, and otherwise has a hollow cavity 155, with at least one side opening or aperture having rim 151 that is spaced apart from the far end of the cavity 155. The aperture is preferably downward facing to prevent contaminating from food spatter or dripping utensils while the cookware article is used.
FIG. 2 illustrates in further details more preferred embodiments of the cookware handle 120, showing the terminal portion 150 having a cavity 155 with an aperture defined by rim 151. The cavity 155 has curved inner sides 154a, 154b, 154c and 154d. Disposed between curved inner sides 154a and 154b is a flat inner upper surface 153a. The rim 151 has an upper edge 152 toward the side thereof most distal from the grip portion 140. The handle 120 is preferably constructed of stainless steel, but may combine other metals, and include a rubber grip coating. The curved inner sides 154a-154d facilitate cleaning and discourage attachment of debris within cavity 155. The curved inner sides preferably have a radius of curvature of at least about 2 mm. Ideally rim 151 terminates close to the bottom inner surface 153b, just above the end of the curve of inner sides 154c, of cavity 155, which along with the inner smoothly curved inner sides facilities draining of fluid that may enter during cleaning It is also preferable that the rim 151 of the aperture is displaced closer to the end of the termination portion most proximal to the cookware article 100 than the opposing which is more distal from the cookware article 100.
Terminal portion 150 is preferably fabricated with a sealed lower portion 157 that engages the opening in the hollow grip portion 140 at a lower rim 158 having the same shape but slightly smaller inner dimensions of adjacent portion of the grip portion 140 to aid in the assembly of handle 120.
Further, the upper portion of the cavity 155 from the upper edge 152 of rim 151 to the inner surface 153, denoted H1, is preferably at least 25% of the vertical extent of the aperture defined by rim 151, denoted as H2. Thus, the portion of the cavity in the direction of the handle 120 that is closed, and not open via aperture 151 is at least about 20% of the total height of cavity 155.
FIGS. 3A and 3B show one mode of using a hanging hook 10 to suspend the cookware article 100 from a fixed upper surface 5. The hanging hook 10 terminates in end surface 11. In this embodiment the end 11 of the hanging hook is optionally flat and supported substantially horizontally to fixed upper surface 5. This flat end 11 enters cavity 155 of handle 120 at rim 151 to support the pan 100 by making contact with the flat inner upper surface 153 of cavity 151.
FIGS. 4A and 4B show another mode of using a hanging hook 10′ to suspend the cookware article 100 from a fixed side surface 5′, but is equally applicable to a hook 10 that can pivot. In this embodiment a portion 11a of the hanging hook 10 enters cavity 155 of handle 150, but cooking article 100 is supported at the upper edge 152 of rim 151 which contacts the distal end of portion 11a, denoted as 12. Portion H1 is preferably at least about 5 mm to secure hook 10′. H2 is preferably about 20 mm or longer to facilitate the user inserting the end 11 of hook 10 into rim 151.
While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be within the spirit and scope of the invention as defined by the appended claims.
