Benefits of technology

The patent describes a way to improve the freshness of a package of produce by allowing some oxygen to enter through a small opening in the lid. This is done while maintaining the low-oxygen atmosphere in the package using a breathable film. The film can be selected based on the specific produce to be packaged and can be designed to allow gas to escape while keeping oxygen out. This helps to keep the produce fresher for longer periods of time.

Problems solved by technology

The patent text discusses the challenge of maintaining the freshness of fruits and vegetables in markets. The text describes the use of rigid plastic packaging and the impact of oxygen levels on the freshness of the product. The technical problem addressed in the patent is the need for a cost-effective packaging system that provides a breathable structure or membrane, while also allowing for the use of a food container system that is simple and not cost-prohibitive for food processors to implement and operate.

Embodiment Construction

[0027]The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, the embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art.

[0028]Referring to the drawings and in particular to FIG. 1, therein is shown an exploded isometric rendition of a rigid polymer plastic construct food container system 1 according to the present invention. The food container system includes a main tray member 4 that is rectangular viewed from above, with a multiple recesses 10, 12 into which a food items such as cut fruits and vegetables is place. As opposed to prior practices, a polymer film or foil is not disposed over the recesses in order to retain th...

Abstract

A rigid polymer food container system for holding fruit and vegetables is described. The system essentially comprises a lid and a tray with complementary mating rims that when assembled together form an airtight seal and which is further releaseably lockable to each other. Additionally, an opening formed into either the lid and/or tray member to permit the flow of air, the opening being further covered with a gas-permeable membrane that is held to the plastic surface by an adhesive. The opening permits some level of oxygenation to delay senescence of the food product and the gas-permeable membrane contributes to minimize bacterial infection and fluid leakage.
