A gripping device for gripping an egg tray (3A) having a dimpled structure includes a gripping unit (4) that is movable up and down to engage and grip the egg tray (3A) and move it. The gripping unit comprises (4) at least a pair of opposite grip ping members (42A, 42B) which are movable in opposite directions, substantially transverse to the up and down movement of the unit (4), from a retracted position to an advanced position to grip a dimple (31) of the egg tray (3A), and from the advanced position to the retracted position to release the dimple. Each gripping member (42A, 42B) of said pair has a separate pressure operated actuator (46) operatively connected to it. The actuator (46), upon pressurization, moves the corresponding gripping member (42A, 42B) from the retracted position to the advanced position.

An egg carton may include a lid having first and second opposing longitudinal sides, first and second opposing ends, a major surface, and first and second denest-features respectively near the first and second opposing ends. Each denest-feature may have an upper wall extending from the major surface, an outward flange being parallel to the major surface, and a curved surface extending from the upper wall to the outward flange. The egg carton may include a base having first and second opposing longitudinal sides, first and second opposing ends, and lower egg receptacles for receiving corresponding eggs, and a hinge strip coupled between the lid and the base and configured to permit the lid to fold between a closed position and an open position.

Plastic egg cartons having mating cell and lid posts for improved egg protection. The carton has a base tray and hinged lid, the tray including a plurality of cells for receiving individual eggs, and the tray having a plurality of cell posts each formed at an intersection of four adjacent cells as an extension of the sidewalls of the four adjacent cells. Preferable, each cell post has four generally planar ramp surfaces, one disposed respectively on each of the four sidewall extensions. The lid has a plurality of lid posts for mating with the cell posts when the lid is in a closed position.

Tri-fold egg carton has a base and a cover each having a complementary matrix of egg receiving cells such that, when the cover is assembled on top of the base, the complementary cells encapsulate each egg in an individual cell pocket (see FIGS. 3-5). Each base cell and cover cell includes a central dome and first and second radially spaced apart circumferential hinges that surround the central dome, and lie radially inward of a lowermost standing ring, enabling the dome to move up and down above the plane of the standing ring (in the height direction of the closed carton) between multiple positions to accommodate jumbo eggs of varying dimensions (height and width) to hold them securely in their respective cell pocket. The base and cover further include full height cell posts with mating surfaces that engage in the assembled state. The carton further includes a lid which fits over the cover (of the assembled cover and base), in a secure and locked position

A tray supply device that reduces effort and burden involved in an operation is provided. The present tray supply device includes a tray storage unit, a detection unit, and a distribution unit. The tray storage unit is provided so as to correspond to one of a plurality of accommodation units that cause eggs to be accommodated in trays. The detection unit detects the amount of the trays stored in each tray storage unit. The distribution unit distributes empty trays to each tray storage unit in accordance with a detection result of the detection unit. An orientation change unit is further included, which changes the orientation of the trays so that the trays are accommodable in each tray storage unit.

The present disclosure provides a process. In an embodiment, a process for producing a packaging article includes providing a body having a geometric shape and composed of a three-dimensional random loop material (3DRLM). The 3DRLM is composed of an olefin-based polymer. The body has a sleeve with opposing ends on respective opposing surfaces of the body. The sleeve extends through an interior portion of the body and has an opening at each respective end. Each opening has a closed width. The process includes providing a product having an insert shape. The insert shape has an insert width that is greater than or equal to the closed width of the sleeve opening. The process includes inserting the product into the sleeve.
