Abstract
A casing for omni-directionally protecting a baking tray comprises a base and a frame skirt continuously formed around the outer periphery of the base, wherein the frame skirt is fixedly connected with the outer periphery of the base and comprises an outer side surface and an inner side surface, and the frame skirt has a roughly inverted U-shaped cross section; a method for protecting the surface of a baking tray, which provides a casing with a base and a frame skirt with a roughly U-shaped cross section. The method comprises the following steps: cleaning the surface of the baking tray, placing the base on the surface of the baking tray, and placing the frame skirt on the outer frame of the baking tray.
Claims16
A casing for omni-directionally protecting a baking tray, comprising:
- a base having a top surface and a bottom surface, wherein the bottom surface is in contact with an upper surface of the baking tray;
- and
- a frame skirt continuously formed around an outer periphery of the base, wherein the frame skirt is fixedly connected with the outer periphery of the base and comprises an outer side surface and an inner side surface, and the frame skirt has a roughly inverted U-shaped cross section,
- wherein the frame skirt comprises a first sidewall and a second sidewall corresponding to the first sidewall, and
- wherein the first sidewall is provided with:
- at least one screw groove extending vertically and partially along the first sidewall, and
- a partial non-opened portion above the at least one screw groove;
- and
- wherein the second sidewall is provided with at least one opening extending vertically and entirely along the second sidewall, and
- wherein the first sidewall is correspondingly arranged to the second sidewall to align the at least one screw groove having the partial non-opened portion above the at least one groove with the at least one opening.
A casing for omni-directionally protecting a baking tray, the baking tray is provided with a screw part, the casing for omni-directionally protecting the baking tray comprising:
