A reclosable packaging case for transporting or storing a product, such as a frozen food product, has minimal gaps upon reclosure of the packaging case. The reclosable packaging case has portions of one or more outer top flaps bent and inserted into openings in one or more inner top flaps. The portions, e.g., corner portions, of the one or more outer flaps are bent at pre-established angles and locations to align with the openings in the one or more inner flaps to ensure minimal gaps in the packaging case once the portions have been inserted into the openings in the inner top flaps, thereby assuring the minimal gaps to help preserve the quality of the product.

A cardboard box erector that folds four flaps provided on edges of an opening of a cardboard box so as to surround the opening is disclosed. The four flaps include a locking flap folded last among the four flaps. The cardboard box erector includes a folding unit configured to fold each of the four flaps in a predetermined order to close the opening, and a pushing unit configured to perform an action to push the locking flap inside the cardboard box and pull the locking flap back. The pushing unit has a suction unit configured to such and hold the locking flap.

A wheel insert for bicycle packaging includes a first insert panel configured to abut a side packaging panel of the bicycle packaging; and a second insert panel laterally offset from the first insert panel and configured to be spaced from the side packaging panel, the first insert panel defining an insert opening therethrough for receiving a wheel axle of a bicycle that is within the bicycle packaging.

A lid forming device of a cardboard box using a first flap with a slit and a second flap to be extended after being bent into a mountain shape is disclosed. The lid forming device includes first and second folding mechanisms. The fist folding mechanism folds the first flap in a direction of closing the opening. The second folding mechanism bends the second flap into a mountain shape and inserts part of the second flap into the slit of the first flap while extending the second flap. The second folding mechanism includes first and second retaining units. The first retaining unit retains a first face of the second flap located between a free end of the second flap and a bend line set beforehand in the second flap. The second retaining unit retains a second face of the second flap located between an anchored end and the bend line.

Example aspects of bicycle packaging and a method of assembling bicycle packaging are disclosed. The method of assembling bicycle packaging can comprise providing a first packaging body, the first packaging body comprising a first side panel, a first top panel connected to the first side panel at a first bend line, and a primary tab extending from an outward edge of the first top panel distal to the first bend line; providing a second packaging body, the second packaging body comprising a second side panel, a second top panel connected to the second side panel at a second bend line, and a secondary tab connected to the second side panel; engaging the primary tab with a primary slot formed at the second bend line; and engaging the secondary tab with a secondary slot formed at the outward edge of the first top panel.
