The invention provides a method for printing a pattern of ink on a substrate, such as corrugated paperboard, with a relief printing form made from a photosensitive element. The method includes forming an in-situ mask for the photosensitive element, exposing the element to actinic radiation through the in-situ mask in an environment having an inert gas and a concentration of oxygen between 190,000 and 100 ppm, and treating the exposed element to form the relief printing form having a pattern of printing areas. Printing is accomplished by securing the relief printing form to a print press, applying the ink to the printing areas on the printing form, and contacting the ink from the printing areas to the substrate to transfer the pattern of ink onto the substrate.

A honeycomb-shaped panel is formed from a plurality of generally sinusoidally shaped strips of molded fiberboard material each having spaced, oppositely directed flat peaks, the peaks of adjacent strips being secured together to form a plurality of hexagonally shaped cells extending perpendicular to the surfaces of the sheet. The strips may be cut from a single sheet of corrugated fiberboard sheet material and then secured together to form the honeycomb panel, or a plurality of such panels may be secured together face to face with their ribs aligned to form a stack, and selected cuts may be made through the secured, stacked panels to form a plurality of honeycomb panels of desired surface shape and height dimensions. The strips forming the cells are substantially rigid and resistant to collapse of the cells, and form a substantially rigid core when assembled between two flexible fiberboard skins, while the panel is bendable to adopt a desired panel curvature.

The provision of a hardened elevated surface within the a inside die cutting area of a cutting rule to limit and control the extent to which die cut scrap processed corrugated fiberboard sheet material can position itself within the area within the cutting rule before ejection limit the tendency for instability within the cutting rule after the die cut is achieved and to better control the ejection of the scrap processed corrugated fiberboard sheet material to better eliminate unwanted scrap downstream of the die cutting process. Eliminated scrap reduces malfunctions in further processing and helps to eliminate health and contamination hazards in the finished corrugated fiberboard sheet product.

A suspension packaging system can include a foldable member configured to form a cavity as well as a suspension device for suspending an article to be packaged within the cavity. The suspension portion can include foldable portions configured to cooperate with a retention member having pockets. The foldable portions can fit into the pockets and then be folded so as to generate tension in the retention member. The entire device, with the exception of the retention member, can be made from a single piece of material, such as corrugated cardboard, which thus reduces waste and simplifies bulk distribution of such a suspension packaging system.

The power supply plug 611 of an electric apparatus 61 is locked in the cut-in portion 52 in the power supply plug holding member 50, which is then housed between a packaging box 62 and the electric apparatus 61.

A manufacturing line for making corrugated paper has both a conventional feed stock location where stock is fed to the line and a gluing station where the stock is connected to the corrugated medium. The line includes multiple in-line printers that are positioned between the feed stock location and the gluing station. One printer can be used to print a first color or coating on a first portion of the stock, and another printer can be used to print a second color on a second portion of the stock. A center trim pickup can be used to divide the paper stock between the two portions.

A system whereby a collapsible box may be formed in the same way that standard cardboard boxes are made by folding a single sheet of material is provided. Square and rectangular boxes may be constructed which may be collapsed down to compact size and easily popped open. Boxes so constructed remain fully assembled with all seams and edges attached even as they are repeatedly folded and unfolded. The box may be made of corrugated cardboard or plastic and easily folded to a fraction of their open volume. The box may open instantly, and when opened, it becomes structural—that is resistant to applied loads—by “popping” certain points outwards. An element or construction that is comprised of a sheet of material that has been provided with a network of hinges such that when the element is folded its edges maintain a right angle relationship is also provided.

A bulk container is disclosed, having a plurality of substantially planar walls, a plurality of corners connecting the walls, and a top and a bottom both formed by a plurality of foldable flaps. A first corner and a second corner opposite the first corner each have two substantially parallel score lines on an inner side of each corner allowing the corners to fold at an angle of substantially 0° while maintaining the structural integrity of the container. The walls of the container are constructed from a multi-ply corrugated cardboard sleeve made up of two layers of multi-ply corrugated cardboard laminated to each other. Two corrugated cardboard inserts, each having foldable top and bottom flaps are laminated to the sleeve. Also disclosed is a method of manufacturing the container using a number of blanks and inserts.

The present invention relates to a single facer, which comprises a humidifying and heating unit placed on the upstream side of an air pressurization corrugating mechanism for humidifying and heating a corrugating medium and a feed mechanism for supplying the corrugating medium, processed by the humidifying and heating unit, to the air pressurization corrugating mechanism at a given speed. The corrugating medium is supplied at the given speed after the humidification and heating process for the corrugating medium, so that an air pressure to be taken at the corrugation is reducible and a predetermined flute configuration is maintainable. In addition, the spring back of the corrugating medium hardly occurs, which makes it possible to manufacture a corrugated fiberboard sheet with a high shock absorbing ability.

The Beverage Dispensing Box for Office and Kitchen Counters is intended to hold a flexible disposable beverage bag filled with a potable liquid and dispense that liquid under pressure when the spigot is opened. The Beverage Dispensing Box is unique in that it employs the law of gravity. Through the use of a sloped container floor and a weighted pressure plate, a natural force (non-mechanical or electrical) is applied to the flexible disposable beverage bag, thus causing the potable liquid to flow from the bag under pressure at a greater gallon per minute (GPM) rate than that of a typical un-pressurized flexible disposable beverage bag—commonly found in corrugated cardboard boxes such as the Wine-in-a-Box container; and at a greater GPM rate than that of a typical 2.5 or 5 gallon bottled water dispensing apparatus. The Beverage Dispensing Box is designed to sit on office, kitchen or other countertops where no electricity is required for use. The Beverage Dispensing Box is a durable reusable container that will positively impact the environment because it will be manufactured from recycled plastic and metals; and will displace the need for disposable plastic bottles, such as bottled water.

A method is provided for applying adhesive to the flutes of a corrugated sheet web. An applicator roll is provided with a uniform thin coating of adhesive by a metering rod. Exposed crests of the flutes are brought into contact with a coating of adhesive that has been applied to a surface of an applicator roll in order to provide a uniform bead of adhesive on the flute crests. The flutes are compressed against the applicator roll surface in a forward direction relative to the direction in which the web is moving adjacent the applicator roll surface. In one embodiment, the applicator roll has a surface linear velocity greater than the speed at which the web is traveling.
