Abstract

A food package for sliced food products to be maintained with a fluffed appearance, the package including a rigid base member forming a compartment for receiving the food product and a rigid lid sealed to the compartment. Advantageously, the base member includes a bottom wall and side wall portions that are configured to engage the food product to hold the slices in a fluffed arrangement thereof. Preferably, one or more tapered side wall portions hold the food product upwardly toward the lid and inwardly toward a center of the package. In preferred embodiments, the base member and lid provide a rigid-rigid construction of the food package. In preferred embodiments, the food package is also configured to stand-up in a vertical display orientation and does not require the food product be contained within a sealed pouch within the compartment.

Claims

1. A food package for containing sliced food products, the food package comprising:

a rigid base member;

a compartment of the base member in which slices of a food product are received;

a bottom wall of the compartment;

side wall portions of the compartment upstanding from the bottom wall and having a predetermined configuration for engaging the food product to hold the slices in a fluffed arrangement thereof, wherein a side wall portion has a ramp section that extends downward and inward toward the bottom wall at an oblique angle;

an opening to the compartment above the bottom wall; and

a rigid lid covering the opening to contain the sliced food product within the compartment, wherein the rigid lid hermetically seals to the rigid base member to seal the sliced food product within the compartment to avoid the need for sealing the sliced food product in a separate pouch within the compartment.

2. The food package of claim 1 wherein one or more of the side wall portions include a ramp section extending downwardly and inwardly at an oblique angle toward the bottom wall, such that the compartment is tapered and adapted to minimize movement of the sliced food product to be contained therein in order to maintain the fluffed arrangement of the sliced food product.

3. The food package of claim 1 wherein one or more of the side wall portions include a ramp section extending downwardly and inwardly at an oblique angle toward the bottom wall, such that the compartment is tapered arid adapted to push the sliced food product upward toward a viewing window of the rigid lid and minimize a volume of the sliced food product subject to compression forces from the weight of the food product thereabove in order to maintain the fluffed arrangement of the sliced food product as it appears through the viewing window.

4. The food package of claim 1 wherein one or more the side wall portions includes a ramp section that extends downward and inward toward the bottom wall at an oblique angle for holding the sliced food product upward and inward toward a center of the food package.

5. The food product of claim 1 wherein the side wall portion having the ramp section is a rear side wall portion having a rear ramp section that extends downward and inward toward the bottom wall at an oblique angle for holding the sliced food product toward a front side wall portion, such that a center of gravity of the food package is lowered when the food package is stood up on a support surface of the front side wall portion in a vertical orientation.

6. The food package of claim 5 wherein the rear ramp section for holding the sliced food product upward toward the rigid lid, such that a center of gravity of the food package is shifted toward the rigid lid when the food package is stood up on the support surface of the front side wall portion in the vertical orientation.

7. The food package of claim 5 further comprising a foot portion extending substantially vertically from the opening adjacent to the rear side wall portion, the foot portion having a base that is coplanar with the bottom wall, the foot portion for providing support for the food package in a horizontal orientation.

8. The food package of claim 7 wherein the foot portion comprises two foot portions positioned at opposite corners of the rear side wall portion, the base of the two foot portions and the bottom wall forming a tripod support for the food package in the horizontal orientation.

9. The food package of claim 1 wherein one of the side wall portions is configured to support the food package in a vertical orientation on a support surface with the bottom wall extending up from the support surface.

10. The food package of claim 1 wherein each of the side wall portions has an upper section that extends substantially vertically downward from the opening about a periphery of the opening, a portion of the rigid lid adapted to fit within the opening and nest with the upper section.

11. The food package of claim 1 further comprising channels formed in at least a portion of one or more of the side wall portions, the channels extending outward from the compartment and extending lengthwise substantially vertically, the channels adapted to provide structural stability to the food package and to assist in gas flushing the food package.

12. The food package of claim 1 wherein the rigid lid and the rigid base member include a reclosing mechanism for allowing the rigid lid to be reclosed over the opening after the rigid lid is unsealed from the rigid base member.

13. The food package of claim 1 further comprising at least one channel formed in the rigid lid for reducing the likelihood of deformation of the rigid lid upon unsealing the food package.

14. The food package of claim 1 in combination with the sliced food product contained within the food package.

20. The food package of claim 1 further comprising:

a heat seal formed between a portion of the rigid lid and a portion of the rigid base member in order to hermetically seal the sliced food product within the compartment to avoid the need for sealing the sliced food product in the separate pouch within the compartment.

23. The food package of claim 1 farther comprising the sliced food product within the compartment.

24. The food package of claim 1 wherein the oblique angle is between about 65–

75 degrees relative to a vertical axis when the food package is arranged in a horizontal orientation.

25. The food package of claim 13 wherein the at least one channel extends along a direction parallel to a major edge of the rigid lid.

15. A food package having a horizontal orientation and slightly inclined or vertical display orientation, the food package comprising:

a base member having an upper periphery with the package in the horizontal orientation thereof, there being a center of the upper periphery;

a main compartment of the base member for receiving a food product therein;

a bottom wall of the main compartment having a predetermined configuration including a center that is offset from the center of the base member upper periphery to shift the weight of the food product downwardly with the package in the display orientation thereof;

a tapered side wall portion upstanding from the bottom wall along one side thereof that generally lifts the food product away from the bottom wall to shift the weight of the food product forwardly with the package in the display orientation thereof;

a side wall portion opposite the tapered side wall portion that extends generally perpendicular to the bottom wall for being positioned adjacent to a support surface with the package in the display orientation thereof; and

a cover for hermetically sealing to the base member to seal the food product within the compartment to avoid the need for sealing the food product in a separate pouch within the compartment.

16. The food package of claim 15 wherein the base member includes small wells each having bottom walls aligned with the bottom wall of the main compartment to support the base member with the package in the horizontal orientation thereof with the size of the wells reduced relative to the main compartment to maintain stability in the display orientation of the package.

17. The food package of claim 16 wherein the bottom walls of the small wells and the bottom wall of the compartment form a tripod support in the horizontal orientation.

18. The food package of claim 15 wherein the tapered side wall portion holds the food product upward toward a cover of the base member, such that a center of gravity of the food package is shifted toward the cover when the food package is stood up in the vertical orientation.

21. The food package of claim 15 further comprising;

a heat seal formed between a portion of the cover and a portion of the base member in order to hermetically seal the food product within the compartment to avoid the need for sealing the food product in the separate poach within the compartment.
