Mechanically Actuated Plunger Or Platen Patents (Class 53/101)
  • Patent number: 12139285
    Abstract: A system for evacuating and sealing containers filled with product, for example, food product, includes an enclosed, sealed housing wherein the pressure level and the atmospheric content can be controlled. A vacuum shroud is positioned in registry with a container entrance opening in the housing, the shroud connectible to a vacuum source and to a source of replaceable gas to replace the ambient air to be removed from the container. The shroud is advanceable to seal the container entrance opening and is retractable from the container entrance opening. A container transport system inserts the container through the housing entrance opening and into the shroud. Thereupon, a sealing system seals the housing from the ambient after the container has been inserted into the shroud. After the air in the container has been replaced with an inert gas and then the shroud retracted, a closure subsystem applies a cover to the evacuated container.

  • Patent number: 6082078
    Abstract: A method is provided for joining a flexible container to a threaded closure. According to the method, a flexible container is inflated with pressurized gas before applying torque to the container. A base of the flexible container is engaged in a container receptacle of a capping apparatus, then the capping apparatus is operated to cause a neck of the flexible container to engage a threaded opening in the closure. The bottle is then inflated and the capping apparatus is operated to thread the neck of the flexible container into the opening in the closure by causing relative rotation between the flexible container and the closure. The pressurized gas stiffens the flexible container and prevents it from buckling or twisting under torque loads applied to screw the container into the closure.

  • Patent number: 5425402
    Abstract: Two or more of a bottle-cleaning operation, a bottle-filling operation, a cap-dispensing operation, and a cap-affixing operation simultaneously process arrays of equally sized containers in an x-y array by engaging the bottles with movable heads of a head-carrying assembly. The containers can be a compressed array of bottles or a case of bottles in a box or the like. The nozzles for the cleaning and filling operations, and cap-handling devices for the dispensing and affixing operations can be repositioned for change to a new container size, for example with motor driven positioners. At least a subset of the heads are displaced along the axes of the container array, into registry with bottle arrays of the different size bottles. Preferably, each operational system in sequence is independently controlled to effect a container size change, such that the production line can be changed to the new size as the leading edge of containers of the new size arrive at the respective operational system.

  • Patent number: 4982555
    Abstract: The invention relates to a method and a device for the sealing of a container (10) by means of a wafer (20). The container comprises one or more joining means (14, 16) which are adapted so that by a joint (12), e.g. a welding joint, they are connected in a leakproof manner, to the wafer in an edge zone (21) of the same. The wafer is held against a contact surface (32) of a retaining means so as to be moved by the same until it rests in its edge zone (21) against anyone of the joining means (14, 16). While the contact with the retaining means is maintained, the wafer is connected by a fixing means (50) in its edge zone in a leakproof manner to anyone of the joining means through the fixing means supplying energy to the edge zone so that a joint (12) is formed. The invention makes it possible to fix in a leakproof manner a previously cut wafer to the opening part of a container.

  • Patent number: 4745730
    Abstract: An evacuating pump has a hollow cylindrical body, a cap at one end of the body, and a nozzle at the opposite end. A plunger disposed within the body has a piston attached to an inner end of a reciprocating rod, while the outer end of the rod extends through a bore provided in the cap. When the plunger is withdrawn, a vacuum is created at the nozzle, while on the inward stroke, a check valve flap seats over the nozzle inlet to prevent air from being injected through the nozzle. Air being compressed on the inward stroke escapes around the peripheral edge of the piston.

  • Patent number: 4694634
    Abstract: A vacuum sealing device includes a plug which is thrust into the port of an insulated steam injection tubing for closing an annular space of the tubing which confines a vacuum. The plug is mounted for movement within a first mounting element and for movement within a bellows having an end connected to the first mounting element. A second mounting element is connected to the opposite end of the bellows and carries a rod which is fixed to the plug. By moving the two mounting elements together, the bellows is compressed and the plug is thrust by movement of the rod. The first mounting element is connected to an upper clamping section which cooperates with a lower clamping section to engage around a tubular to be plugged. The upper section can be correctly centered with its plug over the port of the tubular by momentarily compressing the bellows to extend the plug. The plug is provided with a shank portion and a breakable tab for breaking the plug away from the shank portion.

    Abstract: An assembly for filling and sealing a cavity (14) in a container (10). The assembly includes a fill passage (18) in sealing engagement with the periphery of the receiving passage (12) in the container (10). A vacuum source (24) withdraws gas from the container (10) and the assembly. Powdered material under a vacuum is supplied to a vibrating platform (44) which dispenses the material while vibrating so that the material passes through a valve (48, 52), the fill passage (18) and into the container (10). A plug magazine (26, 125) stores and delivers one spherical ball (28) at a time to the fill passage (18) for being forced into the receiving passage (12) to seal the container (10). A vacuum valve (48, 52) seals the material supply from the fill passageway (18) to maintain the vacuum in the material supply when the container (10) is received.

    Abstract: The invention relates to a method and apparatus for charging a hydro-pneumatic reservoir with gas under pressure. The reservoir is positioned between two vertically aligned supporting members, with the oil charging port and gas charging port of the reservoir axially aligned. The supporting member on which the oil charging port is positioned, is vertically adjustable. The gas charging port carries an initially loose fitting bushing with an expander member at its outer end, the bushing permitting flow of gas therearound to permit charging of the reservoir. A force applying member is slidably mounted in the uppermost supporting member such that when gas under pressure is applied, it will cause the force applying member to move upwardly and the gas under pressure will pass around the bushing into the reservoir to charge the latter.
