Abstract: This relates to the removal of articles from a nest which is travelling along a predetermined path. Most particularly, nests are mounted on an endless conveyor chain and carried thereby past various stations for forming a package beginning with a container, a product placed in the container, and finally a lid. This particularly relates to the removal of such a article as the afore described package. Each nest is provided with a pad or plate in the bottom thereof to be positioned below the container. The plate is carried by a plunger which projects downwardly through the bottom of the nest and also through the conveying chain. In accordance with this invention, the lower end of the plunger engages a ramp which pushes the plunger upwardly as the nest travels along a predetermined path to lift the package out of the nest.

Abstract: This relates to an induction heating coil which is of a single turn construction and particularly configurated for inducing electrical energy into a metal foil barrier layer of a laminated container closure for effecting heat bonding of the closure to a container in a preselected seal pattern. The seal pattern contains either one corner or the closure is provided with a projecting pull tab wherein there is a greater heating requirement and thus a requirement for the induction of higher electrical energy into the closure. The need for the induction of a greater amount of heat into the closure at a corner or the location of a projecting pull tab is provided for by reducing the cross section of the heating coil at the location of the greater heat requirement. The reduction in cross section is primarily effected by forming a notch in the heating coil. If desired, a closer control of the heating effect of the coil may be obtained by positioning in the notch a ferrite insert.

Abstract: This relates to an induction heating coil which is of a single turn construction and particularly configurated for inducing electrical energy into a metal foil barrier layer of a laminated container closure for effecting heat bonding of the closure to a container in a preselected seal pattern. The seal pattern contains either one corner or the closure is provided with a projecting pull tab wherein there is a greater heating requirement and thus a requirement for the induction of higher electrical energy into the closure. The need for the induction of a greater amount of heat into the closure at a corner or the location of a projecting pull tab is provided for by reducing the cross section of the heating coil at the location of the greater heat requirement. The reduction in cross section is primarily effected by forming a notch in the heating coil. If desired, a closer control of the heating effect of the coil may be obtained by positioning in the notch a ferrite insert.

Abstract: This relates to an induction heating coil unit which includes a conventional one turn induction coil which has associated therewith a laminated core. The core is formed of electrically conductive metal members and insulating, preferably plastic, members. The core members are arranged in stacked relation over the coil and then the core is normally potted in a supporting structure preferably of a plastic material. Where maximum heat is required, the concentration of the conductive members is increased. By varying the ratio of the conductive members to the insulating spacer members, the desired electrical energy may be induced into a closure having an intermediate metal barrier layer so as to control the heating of the closure and thus the heat bonding of the closure to an associated container.

Abstract: A frame and membrane assembly for a liquid transfer cell wherein the frame has a peripheral portion including opposite faces and one face is planar and the opposite face carries a peripherally outer sealing ring and inwardly thereof an anchoring arrangement for the membrane. Most specifically the anchoring arrangement is in the form of a peripheral groove of a generally dovetail cross section with an outer peripheral portion of the membrane being seated within that peripheral groove and retained therein in interlocked relation by way of a continuous second sealing ring. The second sealing ring, when the cell is assembled, is squeezed so as to both more tightly interlock the membrane with the frame and to form an inner seal between the two adjacent frames.

Abstract: A frame and membrane assembly for a cell subject to fluid flow. The frame includes a peripheral portion having opposite faces which are to be sealed together. One of the faces is planar while the other of the faces is provided with a plurality of grooves. In an outermost groove there is a final sealing ring. An intermediate groove is generally dovetail shaped in cross section and the peripheral portion of a membrane is locked within that groove by a second sealing ring which deforms under pressure to increase the mechanical interlock while further forming an intermediate seal between two adjacent frames. A principal feature is an innermost groove in which there is seated a third sealing ring. The third sealing ring underlies the membrane and when two adjacent frames are brought together in the formation of a cell, the membrane is forced against the underlying sealing ring which deforms and resiliently clamps the membrane against the next adajcent frame so as to form an innermost seal.

Abstract: This relates to an induction heating unit which is particularly constructed for inducing electrical energy into the periphery of a metal foil barrier layer of a closure for a container to thereby heat the closure and heat bond the closure to the container. In lieu of the customary single turn coil, there is provided a multiple turn coil which is mounted in one of two opposing U-sections of a core. The U-sections may either be formed of ferrite or be of a laminated construction. First legs of the U-sections are utilized to clamp a closure to a container while there will be an air gap between the other opposed legs of the U-sections. Heating may be controlled by either varying the air gap or by varying the ratio of electrically conductive members with insulating spacers.

Abstract: This relates to an apparatus for heat bonding a lid having a metallic layer to a plastic container. The container, filled with a product, is seated in a nest and a lid is seated in place thereon. There is at least one corner on the lid and projecting from that corner is a pull tab. An induction heating unit is associated with the lid and presses it tightly against the container while inducing electrical energy under controlled conditions into the metal layer. The induction heating unit is provided with a specific arrangement of ferrite members for controlling the induction of current into the metallic layer. The ferrite parts in conjunction with the induction coil serve to concentrate the induced electrical energy into substantial alignment with the induction coil notwithstanding the fact that there is a corner and there is projecting from the corner of the lid a pull tab.

Abstract: This disclosure relates to a closure having a plastic layer which is to be heat bonded to a plastic outer layer of a container. The closure is provided with a pull tab to facilitate the removal thereof from the container. Heat bonding of the closure to the container is effected by induction heating utilizing a metal foil barrier layer within the closure. By offsetting a portion of the closure in alignment with the pull tab, the bond between the closure and the container may be configurated so as to facilitate the initial peeling of the closure from the container when the pull tab is lifted.
