  • Patent number: 10421601
    Abstract: Processor tray for displaying tubular meat products in an arcuate configuration, and designed to help guide the packer to mold and place curved meat products in the tray. The filled tray is wrapped in film, and the configuration of the filled tray maintains the film taut to avoid leakage. The tray includes a rectangular upper shaped cavity, and a plurality of curved recessed pockets extend below the upper cavity to define a lower cavity. The tray is designed to provide structural rigidity that resists warping and breakage, thus enabling the overwrapped tray to be handled, shipped, and displayed with minimal leakage or breakage. In some embodiments the tray includes features that facilitate de-nesting of a stack of empty trays, and is adapted to facilitate movement of the wrapped package on a moving conveyor line. The tray is easy to manufacture and provides a lightweight and cost effective packaging product.

  • Patent number: 7762396
    Abstract: A cup carrier for holding beverage cups within a range of shapes and sizes is provided. The carrier has a cup-holding socket that has stabilizing shoulders and stabilizing walls extending inwardly and downwardly therefrom. The stabilizing walls include an upper portion having a relatively shallow angle and lower portions having a steeper angle. This extends the stabilizing wall further into an upper region of the socket, thereby enabling the stabilizing wall to contact smaller diameter cups at a higher point in order to increase stability. The upper portion contacts larger cups inserted into the socket. Because the upper portion initially has a relatively shallow angle, it exerts a desirable gripping force on the cups when it is deflected outwardly by the cup's sidewall. The carrier also includes a stepped center cavity for increased strength and rigidity.

  • Patent number: 6409021
    Abstract: A food serving tray, preferably of polystyrene foam, is provided having a base and bounding side walls. The base is formed with at least two bottom walls and at least one partition interposed therebetween. To provide enhanced stability and rigidity to the tray, protrusions, preferably step-shaped, are formed in the side walls located between the crests of the partitions and the top edges of the side walls. The protrusions provide changes in direction in the side walls which enhance the strength and rigidity of the tray. In addition, the bottom walls may be dished concavely so as to have portions extend upwardly. Under loading, the dished bottom walls become flattened and bi-axially stressed to further enhance the overall strength and stability of the tray.

  • Patent number: 6302324
    Abstract: A system for packaging of perishable food products involves initially packaging the food product in a receptacle containing an inert gas atmosphere and sealing a film to the receptacle. The inert gas atmosphere prevents deterioration of the food product subsequent to shipment from a central processing facility. The receptacle includes a sealing flange and a tab portion extending from the sealing flange, to which the film is sealed. To prepare the food product for display at a retail establishment, the tab and the film sealed thereto are removed from the package, to form an opening between the film and the receptacle. An atmosphere exchange operation is carried out through the opening, by inserting a nozzle through the opening and introducing an oxygen-containing gas into the receptacle cavity through the opening. The inert gas atmosphere initially contained within the receptacle is exhausted through the opening.
