Abstract: An octagonal shaped foldable box having a flap locking system. The foldable box includes: eight sidewall sections; a pair of opposing locking flaps extending from two of the eight sidewall sections, each opposing locking flap having a generally trapezoidal shaped tab cut therein for locking a first opposed locking flap with a second opposed locking flap; and a pair of opposing interior flaps, wherein each opposing interior flap extends from three of the eight sidewall sections, and wherein each opposing interior flap includes a first and a second flap edge, and each flap edge includes a fold-over region for forming a sealed corner with two sidewall sections.

Abstract: A pack of cigarettes or of products of the tobacco industry is effectively protected against light, as well as against the loss or the penetration of humidity and the loss of aroma or off flavor of the products it contains, even though it is wrapped in a blank generally comprising only a single layer of material, when particular precautions are taken order to form the corners of the pack. Another advantage of the proposed package resides in the fact that it possesses several opening mechanism at the user's choice, permitting the latter to open his pack either as a conventional soft pack or as a hard pack. A package of this type is particularly ecological since it is preferably made up from a biodegradable material.

Abstract: A rectangular cardboard box made from typically a single cardboard piece comprises a rectangular, tubular body having four walls terminating in end flaps which respectively connect to the walls through fold lines. The end flaps are foldable along the fold lines to close at least one end of the tubular body. The end flaps which are adjacent to each other are separated by a corner and define a first slit extending through the cardboard and along the corner between the flaps from the outer flap ends to a position which is outwardly spaced from the fold lines of the adjacent end flaps, where the first slit terminates. A second slit is defined on the inner surfaces of the adjacent end flaps. The second slit extends outwardly only partially through the thickness of the cardboard piece and defines a line that extends outwardly from the fold line of one adjacent end flap, then extending across the corner between the end flaps, and further extending inwardly to the fold line of the other adjacent end flap.

Abstract: A flat top thermoplastic coated container and blank including side edge panels, a front edge panel adaptable to being folded back onto itself and having an arcuate-shaped perforated line formed thereon, and a cover panel. The perforated line breaks upon the cover panel being opened to form a horizontal, arcuate-shaped pouring edge. The side edge panels are wider adjacent the cover panel than adjacent the front edge panel to effectively control film delamination upon the cover panel being opened and prevent seepage or "wicking" at the side seam upper edge.

Abstract: A bag-less box for flowable materials constructed of a preferably single-wall outer covering, a preferably triple wall liner glued to the inner panel surfaces thereof, and a lid positionable on the outer covering when folded in and assembled. The outer covering is formed by cutting and folding a corrugated blank to define interconnected panels, top flaps and bottom flaps. Gusset fold areas are formed by diagonal through-cuts in the bottom flaps at flap corners adjacent the panels. With the gusset fold areas and the bottom flaps folded in, a self-sealing box bottom is defined such that a liner bag is not needed.

Abstract: A six-sided sealed carton which is formed by folding a generally rigid, unitary, die-cut blank of a composite polymeric material, in which one of the ends is provided with a reclosable pour-out spout that includes an integral part of the blank, at least some of the corners of such carton being self-sealed by webbed areas or gussets which are integral portions of such blank but which are of reduced thickness relative to the major portions of the remainder thereof, such carton being adapted to contain a particulate material which is in direct contact with the inner surfaces thereof. In a preferred embodiment the carton is formed from a die-cut sheet of a composite polymeric material, a major portion of the thickness of which is an expanded polymeric material.

Abstract: A container for shipping and temporarily storing fresh meat cuts which is a corrugated container of right parallelepiped construction and made up of interconnected corrugated panels. Each panel has a kraft paper outer liner with an outwardly facing wire side, a wax impregnated kraft paper inner liner and a medium positioned between the liners. Each opposed side wall of the box is made up of a pair of superimposed major flaps, and minor flaps extend from the opposite side edges of the panels making up the end walls of the box along and against portions of the outer side of the outermost major flap in each of the pairs of major flaps at opposite sides of the box.

Abstract: An open ended carton which includes a moisture barrier membrane liner attached to interior surfaces of a cover. The membrane liner includes first and second hingedly connected attachment sections which are heat sealed to the cover at marginal sealing areas. A pour spout is provided by pivoting one attachment section outwardly from the carton opening. Pressure sensitive adhesive disposed on the marginal areas of the outwardly pivoting attachment section effects a moisture barrier closure of the carton.
