Abstract: A server lid for a container with an integral tear strip tamper evident feature. A tear strip for the tamper evident feature is molded as an adjunct to a base member which forms the closure. The tear strip is joined to the base by at least one frangible web, and hinges about the frangible web to overlie front edges of one or more flaps formed in the server lid. Ultrasonic welds connect the overlying tear strip to the flaps or adjacent the flaps for providing a tamper evident feature.

Abstract: A metal slide lid for a container which is formed from a metal blank, but in which substantially all of the raw metal edges of the blank are shielded by formed shapes. A pair of rolled rails depend from the top portion, are spaced by a sufficient distance to accept a container on which the lid is to slide, and the rolls are such that the raw metal edge is shielded within the roll. The non-rolled portions of the container, particularly the front edge which can be engaged by the fingers, is formed into a tight safety hemmed edge.

Abstract: A lid for a container is provided generally comprising a main body and a door having a flip section pivotally connected to a push section, the push section pivotally connected to the main body. The main body includes a recess that defines a pivot wall. The flip section is positioned to engage the pivot wall and rotate relative to the push section in response to downward pressure on the push section. The floor of the recess includes a dispensing hole sized to dispense large items. Preferably, the dispensing hole is sized to accommodate a person's fingers while gasping an item. Additionally, the flip section of the door includes a sealing ring projecting from the underside of the door. The sealing ring is sized to engage the inner periphery of the dispensing hole to provide a seal to preserve organic or other perishable items.

Abstract: A lid for a container is provided generally comprising a main body and a door having a flip section pivotally connected to a push section, the push section pivotally connected to the main body. The main body includes a recess that defines a pivot wall. The flip section is positioned to engage the pivot wall and rotate relative to the push section in response to downward pressure on the push section. A detent mechanism is used to control opening the door in at least two stages. In the first stage, the detent mechanism substantially fixes the push section in a closed position, and in the second stage substantially fixes the push section in an open position. In one embodiment, the floor of the recess is sloped to increase container space and limit flexure of the push section of the door.

Abstract: A seamless candle can is formed in a blank and draw operation, and includes a complex bottom structure formed at the end of the drawing process. The bottom structure includes an annular base which occupies less than 30% of the area of the bottom surface, and a raised central platform for supporting a wick structure. The platform is raised at least 0.25 inch above the container bottom. A gently sloping surface joins the annular support ring to the central platform. The distance by which the platform is raised and the angle of the connecting surface are adapted to prevent overstretching of the material during the formation of the bottom, so as to prevent the formation of holes in the seamless can which would cause leaks. The central platform serves to support a wick sustainer at a location above the bottom of the can in order to reduce the possibility of flash-over.

Abstract: A die and method of assembling a high torque capacity metal spool. The spool comprises a cylindrical barrel, a pair of flanges and a pair of flange hubs. The die includes a support member and a curling member that is adapted to move relative to the support housing. The die is adapted to be driven towards a matching die to press a spool therebetween. Each curling member includes an annular curling face which is adapted to curl and compress metal edges of the cylindrical barrel, the flanges and the flange hubs into tightened curls. The tightened curls secure the cylindrical barrel with the flanges and flange hubs. Each die further includes a plurality of nibs carried by the support housings which project outward from the curling face of the curling member after the tightened curls have been formed to swage a plurality of detents into the tightened curls of the spool. The resulting detents in the metal spool provide for increased torque transfer between the flanges, the flange hubs and the cylindrical barrel.

Abstract: Presented is a design aid and method for use in designing a two dimensional graphical illustration for a two dimensional sheet to be formed into a three dimensional item such as a decorative tin or metallic container. The graphical design aid comprises a two dimensional graphical surface which defines various regions of relative distortion resulting from the manufacturing process whereby the three dimensional item is formed from the two dimensional sheet. Once the various regions of relative distortion have been mapped, they are preferably filled with a graphical distortion designator such as a fill color and/or pattern. The various regions may conform to or depart from design lines based upon the distortion or function of the resulting region of the formed three dimensional item.
