A clamshell packaging for airtight packaging of foodstuff includes a tray folded out of a single sheet. The tray has at least two adjacent pool parts, each pool part having a bottom wall and upstanding walls arranged around the circumferential edge of the bottom wall. The adjacent pool parts are hingedly connected to each other along an upper edge of a respective upstanding wall, so the adjacent pool parts can be hinged on top of each other to form a closed box. A circumferential, horizontal flange is arranged to the tray to at least some upper edges of the upstanding walls. A plastic barrier foil is arranged in the pool parts and extends onto and substantially covers the flange. The flange includes a seal zone extending along the length of the flange. The seal zone is line symmetrical along the hinge line at the upper edge of the connected walls.

Described are a machine and a method for forming containers from blanks, including a plurality of shaping hoppers, an endless conveyor which defines a feed path and on which the hoppers are mounted in succession and a plurality of pushing elements which are movable in such a way as to follow the respective shaping hoppers along at least a stretch of the feed path and which have a to-and-fro operating movement towards and away from the respective hopper along a direction transverse, preferably perpendicular, to the feed path. The machine also includes folding means disposed along the feed path downstream of the pushing elements and configured to produce, respectively, a top closure and/or a bottom closure of the tubular blank.

A carton. The carton may include a floor panel; a plurality of side panels extending about a periphery of the floor panel, a front tab formed at an upper edge of a front side panel, upper side flaps extending from upper edges of a first end side panel and a second end side panel, and wherein each flap includes a side receiving slot; foldable corner gussets extending between adjacent side panels, wherein the floor panel, side panels, and foldable corner gussets are configurable to form a compartment region; a hingeable lid, including: a lid panel, a front edge flap, a side tab formed on each opposing side edge of the lid panel, and a front receiving slot formed in the front edge flap, wherein the lid panel is configured to cover the compartment region when in a closed position; and wherein the front tab of the front side panel is configured such that when the hingeable lid is in the closed position, the front tab aligns with the front receiving slot and is receivable therein and each side tab aligns with its respective side receiving slot and are receivable therein.

A shipping box includes a plurality of sides and a plurality of bladders. The sides are arranged as a rectangular solid with fixed sides and a top side. The top side includes an openable cover for access to an interior of the rectangular solid. The rectangular solid has a size determined based on dimensions of an object placed in the interior of the rectangular solid. The bladders are arranged on each of the sides and configured to be inflated as a cushioning mechanism for the object while placed in the interior of the rectangular solid. The bladders are made of a material based on a weight of the at least one object.

A rectangular blank has sides X and Y, where a and b are side dimensions, h is height, and r is width, or width reduced by height h, of the periphery region R of the finished packaging. The method includes: producing folding lines B in the blank parallel to side Y at these distances from the latter: B.sub.1: a.sub.1=h; B.sub.2: a.sub.2=h+a; B.sub.3: a.sub.3=2h+a; severing of two severing lines T, each starting from opposite sides X, along one of the folding lines B, or the extension thereof; selecting the distance between two end points E.sub.T of the severing lines T which are closer to an axis of symmetry S.sub.1 parallel to the side X, such that the distance corresponds to a side B″ of the finished packaging or length of a side M of a packaging insert.

A plant for automated packaging of items in cardboard boxes includes a forming station of open sheet boxes starting from a cardboard web, an item introduction system, a box closing station, and a feeding system. A cutting and creasing system at the forming station produces a longitudinal elongate element defining the bottom and top walls and a first pair of side walls of the box, and transverse panels providing the second pair of side walls. A first gluing system bonds the transverse panels to the elongate element by applying hot-melt strips on the side edges of the elongate element, and a pair of suction-cup manipulators applies the transverse panels on the elongate element at the glue strips to obtain a cross-shaped blank. The closing station includes a folding and automatic gluing system that folds and bonds the side walls and the top wall of the box to produce finished packages.

There is disclosed is a cosmetic-product packaging. The cosmetic-product packaging includes an outer container, an inner container and a lid. The lid is pivotally coupled to the outer container. The outer container and the lid are provided with at least one lid projecting tab and at least one container projecting tab, such that a distal end of the lid projecting tab clips onto a distal end of the container projecting tab to secure the lid in a closed position to the outer container. The inner container is mountable within outer container. Furthermore, the inner container, in operation, accommodates a cosmetic product. The inner container is user-accessible when the lid is in open position, i.e. the distal ends of projecting tabs are spatially mutually separated, for accessing the cosmetic product. The inner container comprises customizable holding tabs and a planar side panel of the outer container is reflective.

Techniques for corrugate and chipboard knocked-down case inspection and manufacturing are described. In an example, a piece of cardboard is cut according to a shape of a knocked-down case, and a first plurality of measurements are made. The piece of cut cardboard is scored to create a plurality of fold-lines, based at least in part on the first plurality of measurements, and a second plurality of measurements are made. A fold-line between a major panel and a minor panel is folded, based at least in part on the second plurality of measurements, and a third plurality of measurements are made. A fold-line of a tab of the piece of cut cardboard is folded, based at least in part on the third plurality of measured distances. The tab is glued to a panel of the piece of cardboard to form a knocked-down case.

An egg carton and method and apparatus for forming an egg carton. A main body of the egg carton may be made of a single sheet of material and folded or otherwise bent to form the majority of the carton's interior space. Partition walls may be engaged with slots formed in the main body to define separate storage areas of the interior space as well as help hold the main body in the desired configuration. Hooks on the sides of the partition walls may engage with openings in the main body to secure the main body to the partition walls.
