Abstract: The envelope of the present invention is prepared from a single blank of material to include easy opening means and security features for tamper evident delivery of credit cards, debit cards and other sensitive material. The envelope structure includes a bangtail flap foldably attached to the rear panel of the envelope and folded inside the envelope, a pair of perforated lines located on each side of the rear panel for providing access to the inside bangtail flap, and a separate opening means for the closure flap.

Abstract: This invention relates to a height measurement apparatus for determining volume/density of wood chips on a conveyor. Such structures of this type, generally, employ the use of contacts that ride on top of the pile of wood chips in order to more accurately measure the volume and density of the wood chips.

Abstract: This invention relates to calendering systems. Such structures of this type, generally, employ the use of hard and soft nips to provide excellent smoothness without gloss mottle.

Abstract: This invention relates to an apparatus and method for determining paperboard thermal conductivity. Such structures of this type, generally, determine the thermal conductivity of a planar material, such as paperboard or insulating foams. The apparatus is designed to characterize the heat flow from a heated brass cylinder, through a flat paperboard sample, and into another brass cylinder. The brass cylinders are fully insulated, except at the sample interface. During the test, which is in a transient state, the hot mass loses energy, raising the temperature of the cooler mass as the two masses approach an intermediate equilibrium temperature. Knowing that the brass masses are fully insulated, except for the heat transfer interface, and knowing the physical properties of the masses, the only unknown in the mathematical model describing the experiment is the thermal conductivity, k, of the paperboard sample, which enables its determination.

Abstract: This invention relates to the construction of sleeves for use with paperboard cups. Such structures of this type, generally, employ a paperboard sleeve backed with hot-melt glue dots which are used to improve the insulating characteristics of a paperboard cup to the same level of common polystyrene cups.

Abstract: This invention relates to automotive evaporative emissions canisters. Such structures of this type employ a carbon-filled foam which adds adsorptive performance to the canister without having to enlarge the canister or having to change the carbon in the canister to a higher performance carbon.

Abstract: Paper web formation analyzers can be employed both on operating paper machines at high speed and on cut samples as a desk top unit, so as to unify formation evaluation for both situations.

Abstract: This invention relates to electro-magnetic rappers which are used on precipitators. Such structures of this type, generally, employ the use of a wear guide which reduces rapper liner wear.

Abstract: This invention relates to chemical additive management systems. Such structures of this type, generally, allow a manufacturer to determine if a chemical additive to be used will contain a chemical component or reaction product that is of toxicological concern to the end-user.

Abstract: This invention relates to paperboard lids having a radiation cured overprint varnish. Such structures of this type, generally, protect the graphics which are printed upon the paperboard lid such that the graphics are not distorted and/or marred during the platen sealing process.

Abstract: This invention relates to paperboard composite structures with a glass-coated film. Such structures of this type, generally, improve the shelf life of refrigerated and other oxygen-sensitive products and provide a barrier to flavors and fragrances to maintain product quality.

Abstract: This invention relates to packages which are designed to dispense a pre-determined amount of product. Such structures of this type, generally, include a series of internal folds that allow a pre-determined amount of product to be loaded into the dispensing chamber. This pre-determined amount is then dispersed from the dispensing chamber by the end-user until the chamber is empty.

Abstract: Using induction heaters, two rotating metal bands are heated to a target temperature, continuously sensed by infrared temperature probes and then compressed on either side of a mated pair of paperboard carton flanges in an extended nip. The mated paperboard flange area is then heated by conduction from the metal bands to the activation temperature of the coating material to form a uniform bond between the paperboard surfaces.

Abstract: This invention relates to paperboard containers. Such structures of this type, generally, allow for the container to be formed into a self-locking, pail-like container for holding food stuffs.

Abstract: This invention relates to a fin sealed box, an integrate barrier coating and a relockable fitment closure that are combine to create a novel package which is easily formed, filled and sealed by the packager and easily opened and reclosed by the consumer. Such structures of this type, generally, employ reclose feature such as an audibly relockable fitment breakaway button snap, an tear-away tab, to add even more convenience and tamper-evidence for the consumer.

Abstract: This invention relates to a two piece paperboard package that houses a unit dose product on an internal slide card within an outer paperboard shell. This package may have one or more internal or external lock(s) that prevent the slide card from being pulled out without triggering some type of lock release mechanism. This package is focused around providing a child resistant, senior-friendly unit dose package that can be opened and closed numerous times and then finally disposed of.

Abstract: This invention relates to a method for producing anti-counterfeit paper. Such processes of this type, generally, add a certain percentage of wood fiber lumens which have been loaded with one or more fluorescent agents. These wood fiber lumens would look normal under regular light, but will glow when exposed to various manners of radiation.

Abstract: This invention relates to paperboard materials for carrying static cling vinyl products for transport to end users. Such structures of this type, generally, provide good adhesion for the static cling vinyl product, but allow the vinyl product to be peeled off easily.

Abstract: This invention relates to paperboard laminates for pharmaceutical blister packaging. Such structures of this type, generally, employ a hot melt adhesive and calcium carbonate (CaCO.sub.3) blend which is capable of sealing to polytrichlorofluoroethylene (Aclar.RTM.). Aclar.RTM. film is commonly used for high moisture barrier packaging in pharmaceutical applications.

Abstract: This invention relates sealing of paperboard cartons in order to form an integral structural. Such structures of this type, generally, employ the use of radiation curable, pressure-sensitive adhesives and "spot curing" of the adhesives in order to seal and form the carton.
