Abstract: A container having lid and base portions (1,2) which are moveable between open and closed positions and a locking mechanism comprising: a holding bar (3) within the container moveable between a release position and a holding position in which it prevents the container being opened and a security device (4) which is insertable in the container so as to move the holding member (3) into the holding position and which is secured in this position by a locking device until released by application of a key or release apparatus.

Abstract: The invention relates to an adhesive for securing PCTFE films, especially blister containers to a support structure such as paperboard. In an exemplary embodiment an adhesive hot melt is blended with amides, such as erucamide, and minerals, such as magnesium silicate. The adhesive blend is mixed with optimal mixtures of amides and magnesium silicate. The adhesive blend is extruded onto a support structure such as paperboard.

Abstract: This invention relates to a laminate substrate. An exemplary embodiment comprises a paperboard layer with a heat sealable layer secured substantially adjacent to one side of the paperboard layer. A co-extruded layer is secured substantially adjacent to the other side of the paperboard layer. The co-extruded layer has five layers: a heat sealable layer secured to the paperboard layer, a first tie layer secured adjacent to the heat sealable layer, a semi-crystalline nylon layer secured adjacent to the first tie layer, a second tie layer secured adjacent to the semi-crystalline nylon layer, and a heat sealable layer secured adjacent to the second tie layer. A fourth heat sealable layer is secured adjacent to the co-extruded layer.

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 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 to a method and apparatus for heat sealing polymer coated paperboard substrates with light energy. Such structures of this type, generally, use lasers which allow a very accurate placement of the sealing energy and a controllable energy level.

Abstract: This invention relates to paperboard and plastic composite package structures that combine an intricate thermoformed shell with a paperboard base or cover. Such structures of this type, generally, provide a lightweight package with a good printing surface on the outside of the package.

Abstract: This invention relates to a method and apparatus for heat sealing polymer coated paperboard substrates using a uniform energy distributed light energy beam. Such structures of this type, generally, use lasers which allow a very accurate placement of the sealing energy and a controllable energy level.

Abstract: This invention relates to a process of making 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.
