Abstract: In accordance with the invention, an improved packaging system for protection against the theft of goods by overlabeling comprises a layer of packaging material surrounding the goods, a label adhered to the packaging material, and a transparent film covering the label. In contrast with conventional packaging, the outer surface of the transparent film is provided with an antiadhesive coating to inhibit overlabeling. The transparent film can be smooth or textured. The advantage of texturing, as by embossing, is to reduce the surface area to which an overlabel can adhere. The antiadhesive coating is preferably a composite layer comprising a non-adhesive base coating of silicone and a layer of "tack kill" material such as an acrylic plasticizer for neutralizing a subsequently applied adhesive. The result is that a spurious label applied on the film over the original label readily disengages in the course of ordinary package handling.

Abstract: An apparatus for forming a weld between first and second thermoplastic materials in which the softening temperature of the second thermoplastic material is lower than that of the first thermoplastic material. The apparatus includes a supplier for supplying the first thermoplastic material and the second thermoplastic material to the same weld position with the second thermoplastic material at a first side of the first thermoplastic material, and a projector for projecting a laser beam to the weld position from a second side of the first thermoplastic material.

Abstract: A double zipper pouch having first and second pockets adjacent one another and with a common wall portion, each pocket having an opening for receiving contents such as identification papers. The first and second pockets are formed so that their openings are displaced relative to one another. Pressure actuated resealable fasteners are disposed adjacent the openings in each of the first and second pockets. First and second indicators are also disposed adjacent the openings to provide an indication of the location of the associated opening. The indicators are preferably different from one another so as to provide an identification for the associated pocket. An adhesive material is formed on the back of the first pocket for affixing the pouch to, for example, a package.

Abstract: An improved tray attachment for a chair wherein a mounting mechanism for the tray is attached to the underside thereof, and is provided with a pin extending in parallel with one side of the tray, such pins having a free end for being slidably received in a mounting block, whereby the tray may be moved in forward and rearward directions by such slidable movement and may be pivoted to a vertical storage position about the axis of such pin. The mounting block is also pivotally mounted on a transverse horizontal extension of a vertical rod, wherein the tray may be raised and lowered by raising and lowering the vertical rod, and by fixing such rod to an arm of the chair at its desired height. The pivotal connection between the transverse rod and the mounting block permits the tray to be tilted, and a second vertical rod, attached to the opposite arm of the chair, may be raised and lowered to support the tray in a horizontal or tilted disposition.
