Abstract
A wrapper and three-dimensional package for toasted and other hot food items that includes a sheet with an array of perforations extending through the sheet material between an inner face of the sheet material adapted to contact the food item, and an opposite, outer face of the sheet material. Spicules are formed from the sheet material surrounding each of the perforations and extending away from the inner face of the sheet material. The spicules form standoffs defining an air gap between the food item and the sheet material when the food item is contained in the wrapper, with the spicules engaging an outer surface of the food item to enable lateral migration of steam from the food item, along the air gap and through the perforations.
Claims37
A wrapper for toasted and other hot food items, comprising:
- (a) a sheet material for use in forming a protective wrapping around the food item;
- (b) an array of perforations extending through the sheet material between an inner face of the sheet material adapted to contact the food item, and an opposite, outer face of the sheet material;
- (c) a plurality of spicules formed from the sheet material surrounding each of the perforations and extending away from the inner face of the sheet material;
- and
- (d) the spicules forming standoffs defining an air gap between the food item and the sheet material when the food item is contained in the wrapper, with the spicules engaging an outer surface of the food item to enable lateral migration of steam from the food item, along the air gap and through the perforations.
A wrapper for toasted and other hot food items, comprising:
- (a) a sheet material for use in forming a protective wrapping around the food item;
- (b) an array of punched holes extending through the sheet material between an inner face of the sheet material adapted to contact the food item, and an opposite, outer face of the sheet material;
- and
- (c) the holes having diameter of between about 1 and 3 mm and a spacing of about 2-3 holes/cm2.
A wrapped hot food product, comprising:
- (a) a hot food item;
- (b) a wrapper formed of a sheet material forming a protective wrapping around the hot food item;
- (c) an array of perforations extending through the sheet material between an inner face of the sheet material contacting the hot food item, and an opposite, outer face of the sheet material;
- (d) a plurality of spicules formed from the sheet material surrounding each of the perforations and extending away from the inner face of the sheet material;
- and
- (e) the spicules forming standoffs defining an air gap between the hot food item and the sheet material with the spicules engaging an outer surface of the hot food item to enable lateral migration of steam from the hot food item along the air gap and through the perforations.
A method of forming a wrapped hot food product that maintains crispness and freshness for an extended time, comprising the steps of:
- (a) forming a wrapper sized for wrapping a hot food item that includes the steps of providing a sheet material for use in forming a protective wrapping around the hot food item;
- forming an array of perforations extending through the sheet material between an inner face of the sheet material adapted to contact the hot food item, and an opposite, outer face of the sheet material wherein the perforations include a plurality of spicules formed from the sheet material surrounding each of the perforations and extending away from the inner face of the sheet material, and the spicules adapted to form standoffs defining an air gap between the hot food item and the sheet material when the hot food item is contained in the wrapper;
- (b) placing a hot food item on inner face of the sheet material;
- and
- (c) folding the sheet material around the hot food item with the spicules engaging an outer surface of the hot food item to enable lateral migration of steam from the hot food item, along the air gap and through the perforations.
A three dimensional package for toasted and other hot food items, comprising:
- (a) a sheet material;
- (b) the sheet material defining a three dimensional package for providing at least partial protection to the food item;
- (c) the three dimensional package including an array of perforations extending through the sheet material between an inner face of the sheet material adapted to contact the food item, and an opposite, outer face of the sheet material;
- (d) a plurality of spicules formed from the sheet material surrounding each of the perforations and extending away from the inner face of the sheet material;
- and
- (e) the spicules forming standoffs defining an air gap between the food item and the sheet material when the food item is contained in the three dimensional package, with the spicules engaging an outer surface of the food item to enable lateral migration of steam from the food item, along the air gap and through the perforations.
A three dimensional package for toasted and other hot food items, comprising:
- (a) a sheet material for use in forming a three dimensional package for providing at least partial protection to the food item;
- (b) an array of punched holes extending through the sheet material between an inner face of the sheet material adapted to contact the food item, and an opposite, outer face of the sheet material;
- and
- (c) the holes having diameter of between about 1 and 3 mm and a spacing of about 2-3 holes/cm2.
A method of forming a three dimensional package for toasted and other hot food items that maintains crispness and freshness of the food items for an extended time, comprising the steps of:
- (a) providing a sheet material;
- (b) forming an array of perforations extending through the sheet material between an inner face of the sheet material adapted to contact the hot food item, and an opposite, outer face of the sheet material wherein the perforations include a plurality of spicules formed from the sheet material surrounding each of the perforations and extending away from the inner face of the sheet material, and the spicules adapted to form standoffs defining an air gap between the hot food item and the sheet material when the hot food item is contained in the wrapper;
- and
- (c) forming the sheet material into the three dimensional package wherein the package extends at least partially around the hot food item with the spicules engaging an outer surface of the hot food item to enable lateral migration of steam from the hot food item, along the air gap and through the perforations.
