Abstract: A method of packaging thermally labile goods. The method includes the steps of (a) obtaining a legend correlating some thermally labile goods with a first color and other thermally labile goods with a second color, (b) locating the thermally labile goods to be packaged on the legend and identifying the correlated color, (c) selecting thermally conditioned panels displaying the correlated color from amongst a plurality of panels displaying different colors wherein the panels are color coded in relation to the phase change temperature of the phase change material contained within the panels, (d) lining the retention chamber of a thermally insulated container with the obtained thermally conditioned panels, (e) placing the thermally labile goods to be packaged into the lined retention chamber, and (f) closing the container.

Abstract: A chuck for grasping bottle caps is provided for use in machines for torque-testing bottle caps. The chuck comprises a housing having an open-ended cavity, with an annular plate fastened within the housing's open end. The plate provides a seat for a flat elastomeric ring and also constrains the ring against radial expansion. The elastomeric ring defines an opening to accommodate a cap to be tested. The housing further accommodates a metal pusher member which normally engages the inner end of the elastomeric ring. A camming mechanism mounted within the cavity is arranged to apply a force to move the pusher member against the elastomeric ring and this force coacts with the constraining force of the annular plate to cause the elastomeric ring to expand inwardly into tight gripping engagement placed with a cap disposed within the elastomeric ring, whereby torque can be applied to the cap by rotation of the chuck without deforming the cap.

Abstract: Cap holder means which holds the inner peripheral surface of a cap has an outer diameter which may be shrunk to a value less than and expanded to another value greater than the diameter of the inner peripheral surface of the cap. When the cap holder means assumes a shrunk condition in which the outer diameter thereof is less than the diameter of the inner peripheral surface of the cap, the cap holder means is capable of smoothly receiving a cap from a cap feeder. Upon receiving a cap, the cap holder means may be changed to an expanded condition presenting an outer diameter greater than the diameter of the inner peripheral surface of the cap, thereby allowing caps of any varying internal diameter to be centered with respect to the cap holder means. This allows a smooth delivery of the cap from the cap holder means to a capping head.

Abstract: A radially expansible press plunge comprising two main parts named formation part (1) and expansion part (2) which are movable in relation to each other, and in which the expansion part (2) is arranged to provide an expansion of at least some part (16) of the press plunge when the said main parts (1, 2) are moved together, and in which the expansion part (2) comprises a cup formed expansion body (16), and in which the formation part (1) is designed with a formation surface (12) against which at least parts of the expansion body (16) is adapted to slide when the formation part (1) and the expansion part (2) are moved axially towards each other, and in which the expansion part (2) is materially composed of two different portions, namely an outer press portion (19) for executing the actual radially outwards directed contact pressure of the press plunge and consisting of a wear resistant, temperature resistant and elastic material, and an inner carrier portion (20) of a relatively hard, elastic material, preferab

Abstract: A method of and device for applying foil to a container that has a closure over its upper surface, and especially to a bottle with a head that along with its cap is to be wrapped all the way around with a blank, especially of foil, by applying the blank around the head while leaving part of the blank to project beyond it, wrapping the sleeve-shaped extension to one side against the upper surface of the cap to create an outer cap cover, and pressing it down, especially with a resilient pad.

Abstract: A plunger (4) for joining an inner workpiece (7) to an outer tubular workpiece (2) is disclosed. The plunger includes an expansion element (9) which engages the inner workpiece and crimps it to the outer workpiece. The expansion element (9) is an annular cup-shaped resilient element which is mounted on a part (21) which is movable relative to a body (8) and to a bottom plate (16). The body (8) and its bottom plate (16) are provided with guide surfaces which are spaced apart to provide a space through which the expansion element may pass upon movement of member 21. The guide surfaces constrain the resilient expansion element to move into pressure applying engagement with the inner workpiece.

Abstract: A heatable sealing head includes resilient, yielding cup springs which transmit pressure and heat to a thin cover insertable between the sealing head and the container rim. This cover, which may be metallic and is coated on the underside with a thermoplastic material, is thereby deformed about portions of the container rim. The cup springs are disposed conically in their relaxed state so that their radially outer portions are situated closer to the cover than their radially inner portions, by which they are fixed to the sealing head. For increasing the flexibility of the cup springs, a spacer piece is inserted between an outer cup spring facing the cover and at least one cup spring nearer the sealing head in order to keep the radially inner portions of these two cup springs spaced from one another while leaving a clearance space between the radially outer portions of the spaced cup springs.

Abstract: A thin-walled can body having a terminal curled rim at an open end thereof, has this open end closed and sealed by a diaphragm which is first formed into a dished shape by a forming tool which then cuts the dished diaphragm from a web and places it on the open end of the body. The upturned edge portion of the diaphragm is subsequently pressed into adhesion between a heat-sealable layer of the diaphragm and the curled rim, the latter being hot, by a presser tool comprising a mount carrying a spring-loaded pad. The pad is resiliently deformable and applies controlled pressure directly on the diaphragm, thus effecting complete conformity of the latter to any irregularities of the curled rim.

Abstract: A platen including an annular surface adapted to heat seal a piece of film to the lip of a cup, and a central projection which is hotter than the annular surface to cause greater shrinkage in a central portion than in the surrounding portion of the sealed piece of film. This shrinkage of the central portion and the resultant gathering of the surrounding portion results in a planar central portion of the sealed film with radially projecting ridges and grooves around its periphery. The ridges and grooves draw visual attention to the central portion and features, such as perforations for a straw-hole, located therein.
