Removable Closure Guided In Rotary Movement (e.g., Screw) Patents (Class 220/288)
  • Patent number: 5437387
    Abstract: A container for transporting and storing vessels containing hazardous liquids and a method for making such a container. The container has a cylindrical housing and a cap that screws into the mouth of the housing and is locked by a latch. When the cap is screwed into place, an elastomeric sealing ring on the cap is compressed against the housing to provide a liquid-tight seal between the housing and cap. Interlocking hook-shaped members that project from the housing and from a central location of the latch act as a fulcrum on which the latch can be pivoted. Under the bias of a serpentine tongue, a locking member that projects from an end of the latch protrudes through a bore in the housing and is adapted to be received by a hole in the cap, thus locking the cap until the other end of the lever is depressed to disengage the locking member from the hole of the cap.

  • Patent number: 5348182
    Abstract: A fitment to be attached to an apertured wall of a container or the like is initially formed (as by plastic molding) with a thin cylindrical plastic molding) with a thin cylindrical wall dimensioned to fit inside the aperture in the container. A flange is formed on the exterior of the cylindrical wall to fit against the exterior of the container wall, surrounding the aperture therein. Preferably the flange slants downward-outward. A curling tool is forced against the end of cylindrical wall, curling it outward-upward to fit tightly against the interior of the container wall opposite the flange, thereby crimping the fitment to the container. Curling of the cylindrical wall may be performed either before or after the fitment is installed on the carton. The fitment is formed to be closed by a cap and preferably to engage the cap in a tamper-evident manner. In a preferred form of the invention the cap and fitment are initially molded as a unitary member.

    Abstract: A child-resistant molded plastic container lid for open head containers wherein a threaded connection is provided between the container and lid. The lid is provided with at least one and in certain instances with a pair of diametrically disposed resiliently biased locking members, pivotally connected to the closure, which cooperate with locking teeth on the container. The lever arms of the locking members are offset and substantially parallel to each other on opposite sides of the pivotal connection. An elliptical spring is integrally connected to each lever arm and cooperates with portions of a gusset wall enclosing the lever arm to provide continued biasing memory on the locking member. A seal arrangement is also provided between the lid and the container to provide a tight and rigid seal and to reinforce the top of the container and lid to prevent the lid from popping off the container when it is dropped while full of liquid or powder material.

  • Patent number: 4964562
    Abstract: A construction for attaching a flanged pour spout to a gable top type paperboard carton blank for packaging potable liquids. The blank is provided with a barrier layer on its inner and outer forming surfaces, and a pour spout extending out from one gable forming panel. An opening is die cut in this panel, and the barrier layers applied. These layers span the opening. Thereafter, a pouring aperture is cut in the barrier layers which span the opening. An annular seal between the two barrier layers is formed by pressing the layers together while applying ultrasonic vibrations to them. The flange of the pour spout is adhered to the outer barrier layer, also by pressing and applying ultrasonic vibrations. By this construction, the edges of the opening in the paperboard are sealed and cannot contaminate the liquid within a carton formed from the blank.

  • Patent number: 4909434
    Abstract: A liquid-containing paperboard laminate carton including a one-piece plastic spout having a pair of opposing flanges sealed about an aperture in one of the carton walls to both the innermost and outermost surfaces of the carton wall. The double flange configuration not only forms a mechanically positive interlock between the plastic spout and the carton wall, but even more importantly, isolates the cut edges of the aperture from exposure to liquid either from within the container or from the environment through which the carton must pass from the point of manufacture until it is ready for disposal after its contents have been consumed. The spout preferably includes a liquid passageway having a membrane-type seal across its discharge orifice to provide evidence of tampering and a resealable closure member such as a screw cap or a snap-on closure held in place by means of a mating ring or groove on the spout.
