Abstract: A thermoplastic bag structure comprising a front and rear bag wall, a bottom and an open mouth top portion, said open mouth portion being characterized by having two pairs of single film handle loops each of which are located at opposite ends of said open mouth portion, the handles of each pair being side-by-side and each handle is an integral single film loop extension of said front and rear bag walls. The bag structures can be unitized by providing a detachable tab at the bag mouth opening and unitizing the bag structures through this tab. The method of forming said bags involves providing an end sealed collapsed thermoplastic film tube and removing plastic to form a bag mouth opening and handles at one end thereof. The resulting bag is an ungussetted bag which can be unitized into a pack by providing a detachable, unitizing tab at the bag mouth opening.

Abstract: A cosmetics case holds one or more cosmetic pencils in a flat hollow container body having a plurality of openings on one side to receive the cosmetic pencils, lipsticks, or the like. A holding body is slidable in the container body and releasably holds the cosmetic pencils or the like. The holding body slides between a retracted position and a projected position which projects a portion of the cosmetic pencils or the like from the opening. One or more springs urge the holding body to the projected position and a retainer releasably retains the holding body in the retracted position to control the desired position of the cosmetic pencils.

Abstract: A fragile article such as an electric lamp having a glass bulb of spherical, paraboloidal or general pear-shaped configuration is protectively packaged by inserting it into snug slip-fitted relationship with an open-ended hexagonal sleeve-like carton of boxboard or other suitable packaging material. Parts of opposing walls of the carton are cut, scored and interconnected to provide a foldable flap assembly that is automatically actuated when the carton is expanded from collapsed condition and is then converted in "snap-like fashion" into a laterally-extending platform that locks the carton in its fully-erected tubular configuration. The platform is provided with a suitable aperture which frictionally grips the basal end portion of the inserted lamp and thus holds the lamp in loaded position within the carton.

Abstract: A microscope drape fabricated from a very thin, transparent heat-resistant plastic film which is adapted to completely house an operating microscope including its support arms, is provided with an improved means for securing the tubular ocular housing extension of the drape to the oculars of the microscope which consists of a thin malleable strip attached to the ocular housing which permits the ocular housing to be secured to the microscope by crimping and folding over the metal strip after positioning the ocular housing on an ocular of a microscope.

Abstract: A package assembly for transporting hazardous materials including a bottle containing a hazardous material disposed within a metal can wherein the bottle is surrounded on all sides by individual upper, lower and side absorbent non-resilient and frangible synthetic resin foam elements. The foam elements provide cushioning for the bottle and absorbency in case of spillage. The individual foam elements are maintained out of contact with each other by means of fiberboard spacers. The spacers are disposed to separate the upper and lower ends of the bottle from the resin foam and to protect the frangible foam from disintegration due to abrasion by the bottle. The metal can be suspended within an outer corrugated fiberboard box by means of a fiberboard insert element for the outer box. The fiberboard insert element supports the can out of contact with the outer fiberboard box and provides a protecting buffer zone between the can and the walls of the outer fiberboard box for the protection of the can.

Abstract: An elongated hanger of the "Pegboard" type is packaged with loose hardware in a paperboard carton by the supplier of the hardware. Upon receiving the carton, a retailer removes the outer and upper end portion of the carton to form a display and access opening in the carton, removes the hanger from the carton through the opening, attaches the hanger to an upright display panel and then suspends the carton from the hanger by causing the hanger to telescope into the inner end of the carton and to underlie the upper wall thereof. In this way, the merchandise is displayed in an open carton which is supported in outwardly extending relation from the display panel by the hanger.

Abstract: A pad of plastic bags comprising a plurality of bag units stacked upon one another, each unit comprising two open-mouthed pockets separated by a selvage portion between the open mouths, the open mouth of one pocket being in the reverse plane from the open mouth of the other pocket whereby when the unit is folded over on the selvage portion the open mouths of both pockets face in the same direction, and transverse score lines in the selvage portion adjacent each open mouth to permit tearing away of each pocket in the unit from the selvage portion, the selvage portions of all the units being connected to form a base portion.

Abstract: A bag pack and individual bags characterized by having handles which are integral extensions of the front and rear of said bag. The bags have a mouth which includes stress relief curves on both sides of an upperly extending tab. The tab includes at least one orifice adapted to securely surround a suspension means. Below or below and above and closely adjacent to said orifice is bonding means fastening all of said bag structures together and simultaneously contributing rigidity to said orifice. Below said bonding means an above the points of maximum amplitude of said stress relief curves is a line of preweakening in said tab to accommodate tear-off of individual bag structures from said pack.

Abstract: A round trip mailer box is formed from a unitary corrugated cardboard blank with a plurality of scored lines for a quick and easy folding of panels to set up the box. The corners of the box are reinforced and strengthened by folding and bracing corner panels. The folding of the box is completed by inserting tabs on two interchangeable and overlapping top panels, one over the other, into cutouts on opposite sides of the box. These overlapping top panels can be interchanged so that when a mailing label is placed on each top panel, the box can be mailed to a recipient and later remailed back to the sender by simply interchanging the relative positions of the top panels. The box is easily secured in its closed position by taping or other closure means at the two inserted end tabs of the box and is easily opened, reclosed and reused.

Abstract: A can carrier suitable for carrying a six-pack of cans including a top plate, bottom plate and spacer holding the top plate and bottom plate in relative position. Each part can be constructed from a sheet of plastic. The top plate and bottom plate each include arcuate recesses defining arcs of greater than 180.degree. to contain the cans. The recesses in the top plate are such that the can body is closely received therein and the can is prevented from dropping from the carrier by the engagement of the top flange on the can with the top plate of the carrier.

Abstract: A sheet metal tray for retaining corrugated fin strips for heat exchangers has a plurality of upright partitions spaced laterally apart to accommodate the corrugated strips.

Abstract: A thermoformed structural foamed plastic container for electrical circuit boards and the like is provided with a conductive outer surface to dissipate electrostatic charges which can adversely affect the circuit elements disposed within the container. The container is preferably formed of integrally joined clamshell sections which are connected by an integral hinge and are provided with suitable support bosses and the like for securing an electrical circuit element within the package interior. The entire exterior or interior surface of the container is provided with a spray or brush deposited or vacuum applied conductive coating comprising carbon or other metallic substances. The container may be formed in two separate sections joined together with interlocking tabs and slots which provide electrically conductive engagement between the container sections.
