  • Patent number: 4140235
    Abstract: A two-part closing arrangement for packing containers of plastic material comprises an internally threaded tubular body of a soft plastic secured to an inturned lip at the mouth of the container and into which is screwed a stopper-like cap also of plastic material and which is provided with a down-turned flange overhanging the mouth to be gripped by the user for applying and removing the cap.

  • Patent number: 4132051
    Abstract: A method of manufacturing packing containers from a thin flexible plastic material intended to be enclosed within an outer shell of stiffer material for reinforcing purposes in which a plastic tube is extended from an annular extrusion die into which a filling pipe extends. The filling pipe is divided into a number of branch pipes arranged in a row and each of these branch pipes is entered into a corresponding longitudinally extending section of the interior of the extruded tube established between parallel spaced sealing zones formed between the front and back walls of the extruded tube which is expanded and thereafter somewhat flattened for this purpose. Longitudinally spaced transverse sealing zones are then formed across the flattened and filled tube sections and cuts are then made through the longitudinally and transversely extending seaing zones thus dividing them into individual filled containers.

  • Patent number: 3952900
    Abstract: A cap type structure for closing a pour-out opening in the top of a packing container wherein the pour-out opening terminates in an outwardly turned flange portion which engages and interlocks with an inwardly turned flange portion on the cap which is made of plastic material and a sealing ring of thermo-plastic material is located between the inter-engaging flange portions. The cap is removed by means of a pull tab which is secured to the flange portion of the cap which causes the flange to be torn off.

  • Patent number: 3935968
    Abstract: A composite container structure for fluent materials such as a liquid which is composed of an external cylindrical sleeve made from a relatively rigid material and an internal cylindric liner of plastic material for receiving the liquid. The internal liner terminates in a hemi-spherical bottom within the sleeve and the upper portion of the liner which projects beyond the sleeve has a dome-shaped configuration which terminates in a central inturned threaded neck forming a filling and pouring opening that is closed by an externally threaded plug portion of a screw type cap.

  • Patent number: 3936662
    Abstract: An interlocking system includes a number of individual key elements such as an identity card each of which has a pre-determined code marking consisting of a number of index elements arranged to form a pattern. At least one interlocking device adapted to co-operate with the key elements includes a release element sensitive to radiation as a function of the radiation pattern pre-determined by the code marking on the key element. The interlocking device comprises a radio-active radiation source, a detector and means such as a slot for interposing the coded key element between the radiation source and the detector.
