  • the present invention can take many different forms.
  • the base tray and its corresponding outer enclosure component can be square, elongated rectangular or otherwise, when viewed in plan view.
  • the base tray compartments are preferably formed from a single sheet of material.
  • the flexible transparent film which extends across the top of the base tray is preferably in a taut condition.
  • taut condition refers to the interaction between the rigid base tray and the flexible film, whereby the film is drawn from its attachments to the peripheral and internal flanges of the rigid base tray generally straight across the top of the tray, thereby enhancing visualization of the food contents within the compartments of the rigid base tray.
  • the flexible film has a surface area of at least 10 square inches (65 cm2).
  • the carbon dioxide content of the gas atmosphere is preferably at least 10 percent by volume.
  • Certain foodstuffs are capable of absorbing the carbon dioxide.
  • the foodstuff may be in such a quantity that a head space provided above the product and beneath the flexible film is from 20 to 90 percent.
  • a package of this type allows for an easy packaging of the foodstuff and employs standard packaging material and standard packaging methods.
  • the outer enclosure component is generally box like in order to facilitate handling, shipping, storage, display, etc. of the package. This outer enclosure component will essentially be opaque except for the opening(s) therethrough which permit visualization of the foodstuff with the base tray.
  • the package is essentially square as viewed in plan view, the base tray including one large recessed compartment and a pair of smaller recessed compartments.
  • the package may be an elongated rectangle, the base tray including a larger number of recessed compartments.

  • Figure 10a illustrates a variation of the invention, showing a base tray with straight side walls and a bottom, this view being a cross-sectional view taken along a line corresponding to line 10-10 of Figure 5.
  • Figure 11 is a top plan view of another embodiment of a package made in accordance with the present invention.
  • Figure 12 is a bottom view, showing the opposite side of the package of Figure 11.
  • Figure 13 is a front elevational view of the package of Figure 11, taken in the direction of the arrow A of Figure 11.
  • Figure 14 is a right side elevational view of the package of Figure 11, taken in the direction of the arrow B of Figure 11.
  • Figure 15 is a top plan view of the base tray of Figure 11, removed from the outer enclosure component.
  • Figure 16 is a bottom view of the base tray of Figure 15, showing the opposite side thereof.
  • Figure 17 is a front elevational view of the base tray of Figure 16, taken in the direction of the arrow A of Figure 15.
  • Figure 18 is a left side elevational view of the base tray of Figure 15, taken in the direction of the arrow B of Figure 15.
  • Figure 19 is a right side elevational view of the base tray of Figure 15, taken in the direction of the arrow C of Figure 15.
  • FIGs 1 through 4 illustrate a package 10 made in accordance with the present invention, the base tray of which is shown separately in Figures 5 through 10.
  • This package 10 comprises an outer enclosure component 11 which encloses an inner base tray 12.
  • the outer component 11 includes a top 13 which is generally opaque except for a plurality of windows 14, 15 and 16 which are located so as to allow one to see through the outer component 11 to view the contents in the base tray 12.
  • This embodiment includes a pair of opposed side walls 17 and 18 and a pair of opposed end walls 19 and 20 and a bottom 21.
  • the base tray 12 is shown separately in Figures 5 through 10, removed from the outer enclosure component 11.
  • the base tray 12 is formed from a piece of material into a shape which includes peripheral flanges 33 which extend completely around the periphery of the base tray and internal flanges 34 which run between the various recessed compartments.
  • the peripheral flanges 33 and internal flanges 34 are located in a common plane which is conveniently referred to as a reference plane.
  • the base tray has three recessed compartments formed therein, namely two smaller recessed compartments 35 and 36 and a larger recessed compartment 37.
  • this base tray 12 is covered by a flexible transparent film 31.
  • the top surface of the base tray lie closely against the inside of the top of the outer enclosure component 11, as is apparent for example in Figure 3.
  • the package constitutes a neat, easy to handle, easy to ship rectangular package while concurrently permitting relatively easy viewing through the outer enclosure component of the food products within the recessed compartments of the base tray.
  • Figure 10 illustrates one compartment 37 of the base tray 12 in cross-sectional view with foodstuff 37a contained therein.
  • the base tray is rigid and would generally be made of plastic. Suitable plastic materials include acrylonitrile copolymers, polyesters, polypropylene and the like. As illustrated, the rigid base tray has side walls providing the compartments with a depth of at least 0.35 inches (8.9 mm) and preferably 1.0 inch (25.4 mm).
  • the flexible film 31 is taut and is preferably of a clear plastic material. Suitable materials include polyester, nylon, polyethylene and the like. The materials may be monolayered or multilayered, but preferably multilayered.
  • the flexible film is attached to the base tray 12 at the peripheral and internal flanges 33 and 34 so as to airtightly seal compartments containing foodstuff, preferably in a taut condition.
  • the attachment at the flanges may be by any suitable sealing technique such as heat seal, glues, ultrasonic, etc.
  • the foodstuff 37a may include meat, such as poultry, red meats, fish, etc. These types of materials generally absorb carbon dioxide.
  • the volume of the foodstuff within each compartment may be such that the headspace, that is, the free space between the foodstuff and the flexible film 31 is preferably 20 percent to 90 percent and preferably between 40 percent and 75 percent.
  • the foodstuff containing compartment 37a is flushed with a gas atmosphere, preferably such that the carbon dioxide content of the gas is at least 10 percent by volume and preferably 50 percent by volume. Suitable gas flushing techniques are employed.
  • Figures 11 through 19 illustrate another embodiment of the invention.
  • This package is of a different overall shape, being an elongated rectangle rather than square, and includes a larger number and different arrangement of recessed compartments in the base tray and correspondingly a different arrangement of openings in the top of the outer enclosure component for visualization of the food products or the like within the recessed compartments of the base tray.
  • Figures 11 through 19 which are similar to corresponding elements in Figures 1 through 10 use the same reference numerals, but raised by 100.
  • Figures 11 through 19 show a different arrangement of recessed compartments including seven recessed compartments 50 through 56.
  • the narrow ends of the outer component, elements 119 and 120 are located along the long side of the package 110, while the sides 117 and 118 are located on the shorter sides of the package 110.
