A fragile article is enclosed in the central portion of an elongated shock-absorbing cradle supported only at its ends by connection or attachment to the ends of an outer rigid box or framework. The opposite sides of the cradle extend along but are spaced inward of the sides of the box or framework to allow shock-absorbing flexing of the cradle if the box or framework is jolted or jostled during shipment or handling. The cradle can be formed of substantially rigid plastic material and have integ...

The present invention is directed to Tape Packages adapted to house semiconductor devices. The packages comprise a base component having a cover component disposed thereon to form an enclosure to house the semiconductor. A tape lead frame is disposed between the base and the cover and has a plurality of lead fingers extending into the enclosure for electrical connection to the semiconductor component. A spring between the base and the semiconductor device presses the semiconductor device into co...

A method and apparatus for heat sealing a thermoplastic sheet-type lid to a container by means of cooperating jaws, one of which is heated and contains an integral cutting edge for forming a line of weakness in the lid simultaneously with heat sealing to facilitate opening of the container. This jaw may optionally include a second outer cutting edge to aid in separating the lid from the remainder of the sheet.

A device for opening a flexible package is embodied by a planar tab which has a first tab portion for being secured to a flexible surface of a package to be opened and a second tab portion which contains lines of weakening which define a cutter having a cutting edge for enabling the cutter, by finger pressure, to be broken from the second tab portion at the lines of weakening and to be bent out of a plane defined by the second tab portion for exposing the cutting edge of the cutter for piercing ...

A retortable, hydraulically solid, sealed package (10) containing a liquid or semi-liquid food product (24) comprises a thermoplastics container (12) formed by a thermo-forming process and a heat-shrinkable thermoplastics closure diaphragm (20). The closure diaphragm is heat-sealed to a rim (18) of the container after the headspace above the product has been evacuated, and is subsequently subjected to external pressure so as to be non-elastically stretched and made to lie wholly in contact with ...

A two-part letter package comprising an envelope-letterhead blank having a copy area thereon and a reply item attached thereto. The blank is folded and joined or sealed to itself to form a carrier envelope containing the reply item and letter copy. An address area on the reply item is exposed in a window opening through the carrier envelope whereby the reply item may be addressed after the letter package is formed and sealed. Letter packages may be provided in continuous form for personalized co...

Apparatus and method of manufacturing microelectronic packages which have good heat dissipation characteristics are disclosed. A lead frame having a plurality of individual terminals is laminated to a metal base between layers of plastic insulation. A microelectronic circuit chip may now be bonded to an exposed region of the metal base without being subjected to the relatively high temperature involved in conventional package assembly operations. Following the bonding of the chip to the base, co...

Packages of bobbins of sewing thread contain an under-bobbin and another bobbin wound with the same type and shade of thread.

A litter package has a body of litter within a container of waterproof material and is for use by a pet animal after the package has been opened to expose the litter substantially throughout the area of the container when disposed for use. The litter body consists of particles of absorbent material or materials that are chemically neutral when wet. Testing means are associated with the litter and of an indicator type changing color if wetted by urine containing a color-changing reactant indicati...

This invention relates to a pressurized package of the class embodying a container for receiving a product, and propellant means in the container for discharging the product therefrom, said container having discharge means characterized by a cap mounted on said container for opening or closing an exit opening in the container depending upon the relative position of the cap, and a pressure chamber interposed between the cap and the container for returning the cap to its closed position with respe...
