An inflatable pouch for packaging a circuit board is formed from two superposed sheets of an electrostatically dissipative plastic. The plastic sheets are welded together to form two air chambers therebetween, each having a plurality of passages therein and they are folded over along a transverse centerline so as to form a bottom end along the centerline, an open end opposite the bottom end and opposing front and rear walls. The side portions of the front and rear walls are welded together to form the side edges of the pouch. The passages in the front wall adjacent the open end of the pouch include enlarged portions which are transversely offset from and interengageable with corresponding enlarged portions in the rear wall to prevent a circuit board from sliding out the top of the pouch. Both air chambers are inflatable through a single inlet aperture which is sealable with a clamp.

A method of making a jewelry display card includes the steps of welding a plastic hanger member on the rear side of a plastic card member so that the hanger member is spaced inwardly by at least approximately one-sixteenth of an inch from the perimeter of the card member, overlaying a foam pad on the front side of the card member, overlaying a flexible, plastic sheet on the foam pad and welding the flexible, plastic sheet to the card member along a welded seam which extends around substantially the entire perimeter of the card member.

A method of forming a jewelry clutch includes the steps of molding an inner gripping piece from a substantially solid, elastomeric, thermoplastic material and forming a plastic outer casing having an opening at one end thereof around the gripping piece. The method further includes the step of inserting an elongated stud or post into the opening in the casing so that the post penetrates through the gripping piece to form a substantially resealable opening therein. The clutch formed by the method can be installed on the post or stud of a jewelry item so that the stud passes through the opening in the outer casing and is received in the resealable opening in the gripping piece to releasably retain the post in the clutch.

A display assembly includes a channel member which is adapted to be received in a substantially horizontal, upwardly facing disposition on a supporting surface, a hanger member which is receivable in engagement with the channel member and a package member which is receivable on the hanger member and operative for supporting and displaying an item in front of the supporting surface. The hanger member includes an engagement portion which is receivable in engagement with the hanger member and at least one arm which extends outwardly from the engagement portion, and the package member is receivable on the arm of the hanger member. In a first embodiment of the display assembly the package member comprises a display box which is releasably receivable on the arm and operative for supporting and displaying an item contained in the box. In a second embodiment of the display assembly, the package member comprises a package such as a display card which is receivable on the hanger member so that it is operative for displaying an item in front of the supporting surface.
