The insulated insert is made of a foamed polyurethane body to which on all sides, except its bottom, a thin, flexible, unfoamed polymer bag is integrally bonded. The bag is a unitary structure having a generally uniform rectangular shape, the bag being formed by sealing shut one end of a tubular member with a transverse seam and forming longitudinal creases extending from opposite ends of the seam. The inner box, which is snugly, but removably, disposed within the insert, is preferably made of corrugated fiberboard and is shaped to include a rectangular prismatic cavity bounded by a plurality of rectangular side walls and a closed bottom end, the top end thereof being open. The closure member is a thick piece of foam material snugly, but removably, disposed in the open end of the inner box.

A corrugated web having tapered flutes is usable in straight-through flow filter elements. The corrugated web can be made by passage between a pair of corrugated rollers having tapered teeth. Methods of making usable corrugated rollers include methods for generating the tapered teeth at the end points and the extension between the end points. Corrugated webs may be made from a variety of media, including certain media that stretches in the machine direction. Methods of forming the corrugated web into filter elements (e.g., air filter elements) includes forming filter media by securing a flat sheet to the corrugated web. The filter media may then be wound into a filter element, including application of sealant during the winding process to close selected flutes.

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 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.

A shipping pallet compatible with fork-lifts and pallet-trucks is made from stamped or die cut flat corrugated board.

Formed between the adhesive pre-metering roll and the adhesive applicator roll is an adhesive pre-metering nip where pre-metering of the adhesive takes place. Between the adhesive applicator roll and the adhesive re-metering roll, provision is made for an adhesive re-metering nip where final re-metering and calibration of the adhesive film takes place.

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.

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.

A corrugated paperboard wraparound blank for forming a shipping case is provided, including five wall panels and four sets of end flaps connected via fold lines, at least two sets of stacking tabs, and at least two corresponding sets of receiving slots for receiving the stacking tabs. The wraparound blank is formed of a heavier material than a conventional blank, which would typically be difficult for automatic packaging equipment to form into a case, but the fold lines are creased with optional perforations or scoring. An optional modification aiding folding is presented for conventional case packers. The heavier fiberboard better supports and protects an inner product, such as cartons or paper bottles of liquids and reduces damage to the cap and neck. The heavier material in combination with the stacking tabs allows an increase in stacking height, thereby reducing transportation costs.
