  • Patent number: 4866906
    Abstract: The present invention provides a device for fixedly securing a cap and body of a capsule together to thereby render the capsule tamper evident. In one form of the invention, the capsules are conveyed at spaced intervals along a predetermined path of travel through a treatment zone which is generally perpendicular to the longitudinal axis of the capsule. An elongated bar having a tapered edge and positioned within the treatment zone engages the side of the capsule to produce an indentation in the side of the capsule which increases in depth from the entry and to the exit end of the treatment zone. This indentation around the capsule hermetically seals the cap and body of the capsule together so that the cap and body cannot be separated without destruction of the capsule. In another form of the invention, the bar is increasingly heated along its length so that, in addition to forming an indentation circumferentially around the capsule, simultaneously hermetically seals the capsule cap and body together.

  • Patent number: 4820364
    Abstract: The present invention relates to a method for sealing capsules to render them both tamper-proof and tamper-evident. The method comprises locating a quantity of an adhesion-promoting fluid between the adjacent surfaces of the overlapping capsule wall, and thereafter applying dielectric heat energy in the vicinity of the adhesion-promoting fluid, to cause the adjacent surfaces of the capsule walls to form a permanent bond. Preferably, the adhesion-promoting fluid may comprise a non-solvent for the capsule walls that further has a high dielectric constant. Suitable adhesion-promoting fluids include lower alkanols. The method is capble of rapid operation and is inexpensive by virtue of its simplicity. Reliable capsule seals are achieved that are incapable of violation.

  • Patent number: 4802323
    Abstract: In a capsule-sealing machine comprising a slat conveyor for carrying capsules over liquid binder application wheels and a bucket conveyor for receiving the sealed capsules and carrying them through the air drying chamber, a set of photoelectric inspection heads is positioned adjacent to the slat conveyor, and solenoid valves and air nozzles are positioned adjacent to the bucket conveyor. Signals produced by the inspection heads are delayed, and used to operate the solenoid valves to eject defectively sealed capsules from the bucket conveyor. The inspection heads are carried on a bar supported by brackets having inverted L-shaped slots which allow the bar to be moved upwardly and out of the way so that the slat conveyor can be cleaned or repaired. When the bar is in the inspection position adjacent to the slats, a slot in a lower edge of the bar fits over an adjusting wheel which permits fine adjustment of the positions of the inspection heads relative to the slats.

  • Patent number: 4761932
    Abstract: A capsule sealing machine (10) in which capsules (C) are fed from a supply hopper (16) to a rotating sealing table (12) for banding or sealing the capsules as they pass over a set of sealing wheels (13). The sealing machine has an improved capsule guide (22) for feeding the capsules from the hopper to the table, thereby reducing the cost and complexity of the machine while at the same time enabling a greater number of capsules to be sealed or banded in a given amount of time and space. The capsule guide comprises slotted magazine sections (23, 28 and 30) which are caused to vibrate by a vibrator (48) to promote discharge of capsules from the hopper and to advance the capsules along the slots. In one form of the invention, a capsule orienting device (51) is disposed in alignment with the magazine to orient the capsules in a desired end-for-end relationship before they are discharged onto the table.

  • Patent number: 4677812
    Abstract: A method for sealing an assembled gelatine capsule of the type used to contain and dispense medication is disclosed. An assembled capsule the axis of which is oriented perpendicular to the axis of a thin elongated bar is moved along and in contact with a thin edge of the elongated bar. The surface of the assembled capsule, at a point where the cap and body of the capsule overlie each other, is initially in contact with the thin edge of one end of the bar and the capsule is moved along the length of said bar so that the axis of the capsule moves closer to the edge of the bar. The bar is heated so as to be at a first temperature at a first point between its ends that will melt the gelatine, and the remainder of the bar is at a temperature that will heat plasticize the gelatine. As the capsule is moved along the heated bar it is rotated either by friction between the bar and the capsule or by mechanical means.

  • Patent number: 4667455
    Abstract: Disclosed is a method and apparatus for sealing together two generally cylindrical thermoplastic members, each having a longitudinal axis, an open end and a closed end, so that upon being joined they form a sealed capsule that may be swallowed. One capsule member may be snugly inserted into a vibrating cavity with the opened end of the member available to be filled with an active composition. The other member is placed over the first member and pushed downwardly so that the open portions of both members overlap one another. The overlapping portions of the wall members abut each other at a cylindrical interface band. Vibration causes only the overlapping wall portions of the members to rub together, thereby generating heat around the interface band. The heat, so generated, melts enough thermoplastic material at that band to produce, on cooling, a strong circular bond between both members.
