  • Patent number: 8028498
    Abstract: A Method of Processing a Container and Base Cup Structure For Removal of Vacuum Pressure A plastic container (10) has a wall extending to a lower portion including a pressure panel (20). The panel (20) is transversely oriented and can move from a downwardly inclined position providing a geometrically unstable configuration to an upwardly inclined position providing a geometrically stable configuration to control pressure change in the container. This movement may be provided by suitable actuating means such as rod (22). In the unstable configuration a base cup 50 or any other suitable holder can support the container and enable it to be conveyed in a container handling or processing system.

  • Patent number: 7421831
    Abstract: The system for removing or replacing caps for vials in a fixed array includes a removable cartridge with a plurality of sets of gripper plates corresponding to the number of columns in the array. Each plate has a plurality of gripper arms corresponding to the number of rows in the array. The gripper arms have hooked ends which are oriented in opposite directions in each set of plates. Relative positioning of the gripper arms is varied by one or more rotating cams, which cause the gripper arms on one plate of each set to move relative to the gripper arms of the other plate(s) of the set, varying the combined width and/or relative angle of the gripper arms to manipulate a cap inserted into the end of each vial. The plurality of plate sets and gripper arms allow all vials in the array to be capped or de-capped simultaneously.

  • Patent number: 6655115
    Abstract: An apparatus and an automated method are disclosed by which embossed seals are created in the necks of corked bottles. A die is employed with an image bearing die surface. The bottle moves along an automated bottle track. Molten seal material is introduced into the cavity above the cork in the neck of the bottle. The image bearing surface of the seal embossing mechanism is superimposed over the mouth of the bottle containing the molten seal material. The seal embossing mechanism is centered relative to the top of the bottle. The die surface is extended from the seal embossing mechanism into contact with the surface of the molten seal material. The mechanism is motivated along an automated seal track coincident with the movement of the bottle along the automated bottle track with the image bearing die surface in contact with the molten seal material until the material has cooled so that the die impression will be retained by the sealing material. The image bearing die surface is then retracted.

  • Patent number: 6205744
    Abstract: An embossed seal is formed in a cavity in the neck of a corked bottle over a cork using a die having a die surface with a die image. A first molten seal material is introduced into a die cavity. The die cavity is formed in part with the die surface. The introduction of the first molten seal material deposits an embossed seal portion with an embossed surface. The embossed seal portion is allowed to cool. A second molten seal material is introduced into the cavity of the neck of the corked bottle. The embossed seal portion is brought into contact with the molten seal material in the bottle cavity with the embossed surface disposed on top facing away from the molten seal material. The molten seal material partially melts the embossed seal portion to form a single seal upon cooling. The embossed seal portion is sufficiently cooled and solidified to prevent melting and damage of the embossed surface.

  • Patent number: 5732751
    Abstract: An ink supply container for an ink-jet printer is provided with a main reservoir, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet which is normally closed to prevent the flow of ink. A fill port is provided for directing ink into the reservoir to fill the reservoir. The apparatus and method for filling the ink container includes a nozzle that seals around the fill port and that has valved fluid lines connected thereto for evacuating the container prior to filling and for directing ink into the evacuated reservoir. The nozzle surrounds a plug that is moved to seal the port while the nozzle is still sealed around the port immediately after the container is filled.

  • Patent number: 4729208
    Abstract: A series of syringe bodies with their lower ends closed is filled with a solution of medicine to a predetermined level in the bodies. The syringe bodies are placed in a lyophilizer with the bodies arranged in a predetermined pattern. A plurality of plungers for the syringe bodies is arranged in a corresponding pattern and above the syringe bodies. After the medicine in the syringe bodies is lyophilized in the lyophilizer, a reduced pressure is created in the lyophilizer and the plungers are simultaneously moved into the syringe bodies to a predetermined level above the lyophilized medicine. The pressure within the lyophilizer is then increased to atmospheric and the assembled syringes are removed. Apparatus for implementing the process can include a lower rack having openings for retaining the syringe bodies in the predetermined pattern, and an upper rack seatable on the lower rack for retaining the piston portions of plungers in facing relation to, aligned with, and above the openings of the syringe bodies.

    Abstract: A tool for placing a lid or closure on a cup or container, such as a cardboard or plastic cup containing hot coffee delivered to a customer at a take-out food service establishment. The preferred form of tool has a upright handle with spring-loaded telescopic sections and a bottom member or shoe which fits snugly within an upstanding marginal flange of the lid with which this tool is to be used, so that when the tool is raised, the lid will be carried with it. The tool is manipulated to place the lid on the top of the cup filled with coffee or other liquid. Downward motion of the handle portion of the tool moves the telescopic portions relative to each other, first compressing a spring, and then suddenly releasing the spring with a hammer effect, to drive the lid into mating engagement with the cup, with just the right amount of pressure to produce adequate sealing between the cup and the lid, without damage to either. Alternative forms of tool, not employing the hammer effect, are also disclosed.
