The disclosed systems and methods relate to improved cases for securely storing and shipping products. A case can include a back panel, an upper foldable section, and a lower foldable section. Each of the features of the case can be manufactured on a single sheet of material. The upper and lower foldable sections include panels having apertures for holding the top and bottom of a product, respectively. The case is foldable into a closed configuration such that a lower holder panel, a lower front panel, and a bottom panel form a lower box configured to hold the bottom of the first product, and an upper holder panel, an upper front panel, and a top panel form an upper box configured to hold the top of the first product.

A shipping box comprises a bottom structural flap and a plurality of sidewall structural flaps, of which at least two are connected to the bottom structural flap, and assembly elements that assemble the box in a stable way. The box is foldable in a flat folded position in which, from its upper part, in the use position, to at least three of the structural sidewall flaps are connected at least three functional flaps independent of each other, making the functional flaps the functions of lid, interior space reducer, fastening and/or handle, and that the assembly elements are located on the internal part of the box.

A corrugated corner element including at least some of a portion of material extending from a first terminal end to a second terminal end; a first corner element leg having one or more alternating ridges and grooves; a second corner element leg, extending from the first corner element leg, the second corner element leg having one or more alternating ridges and grooves; and a score mark formed in the portion of material, extending from an area proximate the first terminal end to an area proximate the second terminal end, wherein the score mark provides a line or portion along which the corrugated corner element may be bent or folded.

A foldable blank for forming a carton for shipping and displaying a plurality of products in an integrated tray is provided. The blank includes a rear panel, a first and second side panels both foldably connected to the rear panel, an exterior floor panel foldably connected to the rear panel, and a front panel foldably connected to the floor panel that is less than half the vertical height of the rear, first side, and second side panels and defines at least one retaining tab, wherein when the blank is folded to form the carton, each of the rear panel, first and second side panels, and front panel are at least partially double-walled.

The present disclosure relates to a packaging box and a paperboard structure.

A method of manufacturing a cartridge is described. An injection needle is inserted into a mold that forms a barrel. The barrel defines an open proximal end, an opposing distal end, an internal reservoir therebetween, and an arm projecting distally from the distal end of the barrel and having a portion bent at a fixed angle. The injection needle is positioned within a portion of the mold configured to form the arm of the barrel, and a terminal needle tip is oriented such that a beveled opening of the needle tip is distally facing. The injection needle is stabilized against movement with a gripping device. The mold is filled with resin to form the barrel around the injection needle. The gripping device is separated from the injection needle upon hardening of the resin.
