Covers are provided with channels for directing the outflow of steam and gases through a partially clinched lid of a tray-shaped baking can, while the baking is taking place. The baked product is permitted to rise uniformly, with no deformation that would normally occur when the steam and gases act to depress the baked product if they are confined to the baking can. Because a lighter, lower water-active batter is required for the process of the invention, the resulting baked product is light and evenly baked and has a substantially extended shelf-life.Type: GrantFiled: June 9, 1983Date of Patent: May 20, 1986Inventor: Anthony P.

Patent number: 4586649Abstract: A food package for cooking popcorn in a microwave oven which comprises an inner pouch containing the popcorn kernels, oils and seasoning, an outer paperboard carton in the form of an inverted truncated pyramid and a stand therefor which is adapted to be packaged inside the carton. When the package is to be used, the outer carton is inverted and opened, the stand is removed, erected and placed in a microwave oven. The inverted outer carton is then placed on the stand which insulates the lower portion of the carton. In this position, the popping area of the package is in a position to be affected by maximum microwave energy efficiency and is protected against heat loss for maximum heat efficiency whereby, a higher ratio of popped to unpopped kernels can be obtained.Type: GrantFiled: February 13, 1984Date of Patent: May 6, 1986Assignee: Waldorf CorporationInventor: George P.

Patent number: 4584202Abstract: The package allows the popping of popcorn in situ within a pouch contained in a carton. The carton has a tear-away portion in its top panel which is removed when the package is put into the microwave oven. The pouch is folded in the carton so that the edges of the folded pouch are disposed beneath the opening formed by removal of the tear-away portion. The top panel of the carton includes marginal constraining portions bounding the opening which constrain the pouch once the popcorn has commenced popping. The basal portion of the pouch is thus held in the carton while the remainder of the pouch expands through the opening during popping. The carton is provided with feet which elevate the bottom panel of the carton in the microwave oven to minimize scorching of the bottom panel during popping.Type: GrantFiled: March 29, 1984Date of Patent: April 22, 1986Assignee: Waldorf CorporationInventor: Harry I.

Patent number: 4584101Abstract: A coffee package has a filter assembly double folded and enveloped air-tight in a wrapper in a vacuous or inert gas atmosphere. The filter assembly includes a generally rectangular support plate made up of an intermediate portion with an opening for pouring hot water therethrough and a pair of support legs connected with opposite sides of the intermediate portion. The support legs are formed with coactive nipping members adjacent to their edges such that, when the support legs are folded upright relative to the intermediate portion, the nipping members are firmly engagable with the upper edge of a receptacle to support the whole assembly in the raised position for use. A sack of filter paper open at one end is filled with a weighed volume of coffee powder and adhered to the back of the support plate to cover the opening in the support plate.Type: GrantFiled: February 8, 1984Date of Patent: April 22, 1986Assignee: Kataoka Bussan Kabushiki KaishaInventor: Joji Kataoka

Patent number: 4576278Abstract: The present invention relates to a food tray for supporting, containing and displaying food products which tend to exude or purge juices or liquids. In particular, the present invention relates to a food tray which comprises a sunken exudate reservoir. The reservoir is formed by adhering a sheet of a liquid impermeable material in a liquid tight manner to a raised shoulder area of a support portion of the tray to form a false bottom. The sheet material is further supported by standoffs rising up from the tray bottom. The sheet material is also perforated so as to allow flow of the exudate or purge through the sheet down into the reservoir where the exudate is trapped and retained out of contact with a food product which is located on top of said supported sheet. Preferably, the sheet material is opaque and the exudate is thereby hidden from view. Even more preferably, the sheet material is of the same color as the tray.Type: GrantFiled: September 13, 1984Date of Patent: March 18, 1986Assignee: W. R. Grace & Co., Cryovac Div.Inventors: Stanislaus Laiewski, Thomas A. Hessen, Thomas R. Hardy, Allie F. Gilvin

Patent number: 4573570Abstract: A structural support for a taco, for protecting the taco when packaged in an overwrap, and also serving as a taco stand to maintain an unwrapped taco in an upright position. The support is constructed from an elongated paperboard blank formed into an interlocked structural support with a flat base member and a forwardly projecting front. The front projects forwardly in a substantially semicircular shape such that a taco can be laid on its side on top of the flat base member and within the semicircular front, and the thusly protected taco can then be packaged with an overwrap for sale by a fast food restaurant. The taco support also has a pair of opposed, upwardly facing cutouts therein symmetrically positioned on opposite sides of the projecting front.Type: GrantFiled: June 22, 1984Date of Patent: March 4, 1986Assignee: Taco BellInventor: Jeffery J.

Patent number: 4558801Abstract: A film liner is provided in the form of a sleeve having a conforming seal area provided on the sleeve that joins opposing panels of the sleeve along a location that is spaced inwardly from an edge of the sleeve, and this conforming seal area has a length that is less than the length of the edge from which it is inwardly spaced. When the conforming liner according to this invention lines a container, such as a cheese-making box, the mouth of this liner forms a cuff over the peripheral edge of the container. When thus used, the interior surface including the conforming seal area of the liner provides a relatively flat, crevice-free surface for receiving cheese curd or like products, and excess paneling material is positioned underneath this conforming interior surface and out of contact with the product filling the container.Type: GrantFiled: August 9, 1984Date of Patent: December 17, 1985Assignee: Vilutis & Co., Inc.Inventor: Leonard J.

Patent number: 4552789Abstract: An improved L-type backing board insert for supporting food, such as shingled bacon slices, in a film wrapped package is disclosed comprised of a two-ply laminate. An opaque flexible base ply of pigmented plastic material, such as high density polyethylene, is printed on one side and is provided with a mat finish on the other side. A window aperture is formed in the opaque base ply for viewing both sides of a portion of the packaged bacon. A ply of transparent polyolefinic film, such as polypropylene film, is adhered to the base ply, substantially covering the entire printed face and forming a window over the window aperture formed in the base ply. Use of the polypropylene film provides the backing board with a high gloss finish.The improved two-ply backing board reduces the amount of ink necessary for printing on the backing board, captures the printing between the two layers of the laminate, and yields an inexpensive, flexible and high quality backing board.Type: GrantFiled: February 15, 1983Date of Patent: November 12, 1985Assignee: Huggitt Packaging CompanyInventor: Jack W.
