Abstract: The rim of a pail body is provided with a compound curl for reception of a lid. The compound curl comprises as upper region extending away from the wall of the pail body or its outside, a lower region extending from the outer periphery of the said upper region towards the wall of the pail body and a rim edge part which extends from the inner periphery of the said lower region away from the wall of the pail body and is intermediate the said upper and lower regions whereby a lid applied over the rim with the central part thereof located within said rim can be clamped onto the said compound curl to form a seam therewith.The said lower region and the said rim edge part constitute a smaller pre-curl within the compound curl, the rim edge being spaced below the said upper region so that in clamping on the lid, a region of the said rim edge part is brought into supporting engagement with the said upper region.

Abstract: When the free marginal portions 42 are telescoped within the confines of the peripheral flange 36 preparatory to the soldering operation, inward pressure on the end tank 38 usually is maintained during the soldering operation. Of course, the soldering operation involves the application of heat to both the peripheral flange 36 and the peripheral side wall 40. This sometimes will cause the free marginal portion 42 of the peripheral side wall 40 to deform inwardly away from the peripheral flange 36, thus leaving excessive spacing between the free marginal portion 42 and the peripheral flange 36. In order to avoid this condition, raised dimples 44 are formed in the header plate 34 along the peripheral flange 36 and spaced slightly inward from the latter a distance equal to the thickness of the peripheral side wall 40.

Abstract: In a metal can at least one component having an edge portion forming part of a seam is made from pre-laminated plate comprising a metal substrate with a polymeric film bonded over the whole of one or both of its sides. An aerosol valve cup is made from such plate with its underside having such a polymeric layer, and is secured to the can body in a seam by conventional mechanical deformation, such as swaging, so as to compress the polymeric layer in the seam. This provides a satisfactory seal without the need for any additional sealing material within the seam.

Abstract: A triple seam for assemblying a bottom to a container body, and a process for forming the triple seam. The process comprises the step of forming an axially extending seaming structure comprising a plurality of layers belonging to adjoining edges of the body and bottom. One of the adjoining edges includes a first layer and a contiguous overfolded second layer having an axial length less than the axial length of said first layer to increase the number of layers in a first axial section of the seaming structure. The process also includes the step of lamination rolling the seaming structure to a uniform width. A hook-shaped profile is formed in said body edge as a preliminary step in this process.

Abstract: A reusable industrial drum is formed by temporarily joining the periphery of the end closure to the rim of the cylindrical shell by curling to produce a spiral seam. The outermost layer of the seam, consisting of a portion of the end closure, is cut to permit the end closure element and shell to be separated and disassembled. Further processing operations may take place on the closure element and shell separately. The closure element is thereafter re-mated with the shell, a seam sealant having previously been introduced between the parts, and a locking ring such as a bolt or chime ring is placed over the reassembled seam. The locking ring surrounds the periphery of the seam to hold the seam together. After use, the drum can be readily disassembled for reprocesing and reuse by simply removing the bolt or chime ring.

Abstract: A method is provided for producing an end plate for a container having a continuous wall, with a novel end plate being produced thereby. The end plate includes a thickened plate which is disposed perpendicular to the continuous wall, with the thickened plate having a diameter less than the inner diameter of the cylindrical walls. A sheet having a peripheral down-turned flange is disposed above the thickened plate, with the down-turned flange having a diameter greater than the diameter of the cylindrical walls. An opening is provided in the sheet which is aligned with an opening in the thickened plate. An end portion of the continuous wall is bent outwardly to form a peripheral lip which has an outer diameter less than the diameter of the sheet. A seam between the continuous wall and the metal sheet is formed by inserting a stud into the opening and engaging a groove-containing roller to the down-turned flange and peripheral lip.

Abstract: A vessel with a metal skin particularly well suited for cosmetic use is provided. The metal skin covers the shoulder region from the base of the neck over the side wall and extends inwardly over a substantially planar metal plate adhered to the bottom of the container. The metal skin is formed into a cup shape and the jar is dropped in up-side down and crimped over the metal plate on the bottom. Pre-forming the shoulder region of the metal skin avoids unsightly stress marks in the upper exposed portion of the container.

Abstract: A metal container has a seam which comprises two continuous groups of concentric circular arcs having a center angle of 180 degrees or 180 degrees and under 180 degrees and centered on two points separated from each other by a distance equal to 1/2 of the sum of the thickness of two metal sheets making up the seam. The axis of the seam is a straight line passing through the two centers that can be inclined at any angle with respect to the axis of the container. The seam has a cross-sectional shape that is mostly point-symmetrical with respect to a center that is the mid-point between the two centers. The seam is formed by an apparatus which comprises a seaming roll and a chuck ring, each of which has a forming groove comprising, in cross-section, two continuous circular arcs centered on two points that are separated from each other by the distance equal to 1/2 of the sum of the thicknesses of the metal sheets making up the seam.

Abstract: An improved hermetically sealed composite container formed by double-seaming a pair of compounded metal ends to extended length flanges on the opposite ends of a can body so that the compound is bonded to an inner liner on the can body to provide an effective seal. The compound material is placed in the seaming panel and curl area of the metal ends so as to provide a more extensive seal area when the metal ends are double-seamed with the extended flanges on the can body. The extended length flanges provide a considerably greater contact area between the can body inner liner and the metal ends when the metal ends are double-seamed to the can body.

Abstract: A nesting drum and a method of making the same is provided. The drum comprises a shell which has a necking at the bottom to accommodate a double seam between the shell and the closure. The closure has a raised circular center and a plurality of ribs which re-enforce the shell to resist large loads.

Abstract: This invention relates to a novel lifter construction for rolling filled cans. It is designed to allow a lifter plate to effect relative rotation with respect to a lifter body to be forcibly driven in order to introduce the merits of the free rotation system into a lifter of prior art forced driving system. To this end, there is proposed a construction wherein the lifter plate is driven by a clutch and the clutch is disengaged with lifter pressure, and a construction wherein the lifter plate may be rotated through a given angle on the plate supporting bed. Preferably, a detector is provided to detect an abnormal rolling of cans or the like.

Abstract: A fluid filter of the disposable automotive spin-on type has a cup-shaped member and a closure member which together form a chamber for receiving a filtering media. The cup-shaped member has a relatively thin side wall and an open end defined by a marginal edge including a bead. The closure member is a one-piece stamping of uniform thickness and substantially thicker than the cup-shaped member. The closure member closes the open end of the cup-shaped member and includes an annular rim which extends perpendicularly to the plane of the closure member and generally parallel to the side wall of the cup-shaped member. A channel defined by the rim receives the bead of the cup-shaped member and the rim is crimped to form a fluid-tight connection between the members.
