  • Patent number: 4779776
    Abstract: A seeding device to dispense seed suspended in a gel or other carrier medium in either a continuous stream or discrete pulses. A coulter opens a furrow of earth to the proper depth and seed carried in a gel or other suspension medium is delivered in a pulsed or continuous stream into the furrow which is then covered with earth by a trailing coverer. An auger delivers the seed in suspension and the speed of the auger is controlled to vary the volume of seed and gel or other suspension medium delivered. Circumferentially spaced cam lobes on a drive wheel control the frequency and therefore the row spacing of the seed suspension medium distributed in the pulse delivery mode.

  • Patent number: 4753371
    Abstract: S-shaped opening and closing element for controlling the flow of a fluid or body (powder, granulate) and adaptable to any form of package or fitting containing fluids, characterized in that its shape in two S-bends permits both an instantaneous stoppage of the flow of the fluids and an instantaneous flow of said fluids; this, as a function of the given position, by manual or mechanical traction on the element. The S-shape ensures very effective fluid-tightness, without supplementary elements. The opening and closing element can be employed for controlling flow from a container having a supporting device for the element. The container can have more than one compartment.

  • Patent number: 4749103
    Abstract: A child resistant dispensing closure having a pourout style spout that is telescopically mounted on a cylindrical extension of the closure. The closure is described with two embodiments of a push-pull spout. In both cases the closure threads onto a container finish and a pourout spout of the push-pull type is mounted on a cylindrical extension of the closure. The closure extension has a side opening adjacent the closed upper end through which the contents may be dispensed. The spout effectively closes the opening when in assembled form. Interengaging beads and lugs formed on the exterior of said closure and interior of said spout define the only relative rotational position that permits the spout being pulled up on the closure to uncover the opening therein. The proper rotational position is indicated when indicia on the spout and closure are aligned.

  • Patent number: 4726491
    Abstract: A pour spout container with a pour spout which may be pulled out of the container is disclosed as including a container (10) and a pour spout (24, 48). The sealing cap (20, 50) is provided for sealing the container and the pour spout. Threads (16, 22) are formed between the cap and a container neck (12). Threads (30, 32) are formed between an inner cap (20a, 50a) and pour spout (24, 48). Turns of threads (30, 32) are greater than the turns of threads (16, 22) so that the sealing cap may be removed from the container while remaining attached to the pour spout. Grasping of the cap may be utilized to extend the pour spout fully from the container without contacting the pour spout which has been in contact with the fluid in the container. Thereafter the cap may be removed from the pour spout for dispensing fluid. For this purpose, the pour spout is prevented from turning relative to the container so that unthreading thereof can be accomplished without grasping the pour spout.
