Abstract: A sandwich press or food holder for use with a cooking appliance, such as a toaster or oven. Sidewalls of the press that define a space in which a food item is received can have one or more ridges that define a convex surface inside the cavity and a concave surface on an exterior of the sidewall. The concave surface can be positioned adjacent a heating element when the press is received in a cooking cavity of the appliance. One or more openings can be provided in the sidewall, e.g., to allow radiant energy to pass and/or steam to escape. A handle can permit two-handed manipulation of the press and can have a gripping portion that is offset from an area directly above the press.

Abstract: The present invention provides an immobilized reaction device and a method for carrying out reaction by utilizing the immobilization technology. The immobilized reaction device includes a columnar reactor with an inlet and an outlet. The reactor is provided with an interior cavity which is defined by a top portion and a bottom portion opposite to each other, and a side wall connecting the top portion and the bottom portion.
