Abstract: The present invention provides a fluid dispensing container which more effectively regulates and controls fluids dispensed from the container. The container includes a unique funneling and valve assembly which funnels fluid from the container to a valved pouring spout. The container provides a unique fluid flow through an apertured tubular conduit to which the spout is pivotally mounted. Pivoting the spout opens and closes the valve assembly. The fluid flows through both ends of the tubular conduit, and as a result, the fluid flows more smoothly and uniformly from the container to the spout.

Abstract: A novel container having a plastic pour spout is provided, the container carrying a pour spout having a platform, a first side panel connected by hinge to the platform on a first side and a second panel connected by hinge to the platform on a second side, the two side panels having a substantially triangular shape. The hinged connection of the panels to the platform permit each pour spout to be provided in a flattened configuration in which the side panels are folded relative to the platform for insertion into an unerected carton. Following insertion, the panels again relax along the hinge-line and permit subsequent processing of the flattened carton stock. When the carton is folded, the panels move passively in response to the carton folding steps and assume an assembled configuration as the carton is assembled.

Abstract: A selectively attachable closure for a container. The closure includes a valve member connected to a restraining member by structure for causing the restraining member to be drawn toward the valve member.

The central expandable member is caused to outwardly expand when the restraining member is drawn toward the valve member. The central expandable member includes a hollow body positioned about the restraining member so that the central expandable member is supported by the restraining member. In use, the restraining member and the central expandable member are passed within a hole formed in a container while the valve member is seated on a periphery of the hole to support the closure, and the restraining member is drawn toward the valve member causing the central expandable member to outwardly expand and secure the closure within the hole.

Abstract: There is provided, in conjunction with a container fitted with a toggle-acting dispensing closure cap, a cap-surmounting secondary control cap to render the container "child-resistant". The control cap is sleeved over and is coaxial with and rotatable about the closure cap. Bridging a generally-cylindrical skirt-like wall of the control cap is a partial, sector-like top wall which covers only a portion of the closure cap including the toggle-like actuator used to open and to close a dispensing port of the container. The partial top wall, which is provided with a restricted through opening, prevents one from impressing effective opening forces on a "press-to-open" section of the actuator. Opening forces can be applied to the actuator only by a probe acting through the restricted opening in the top wall sector of the control cap, and then only when that wall sector overlies the press-to-open section of the actuator.

Abstract: A glue gun includes a nozzle body and a replaceable nozzle cap. The body is mounted in a melt casting of the glue gun such that it is rotationally adjustable. Thus, a rotationally asymmetric nozzle cap is more easily used because the nozzle body can be rotated to correct misalignment of the cap due to differences in the orientation of threads holding the cap to the body.A preferred nozzle includes a plurality of openings that allows the application of several small beads. These beads can be pressed into a thin layer if delay tack adhesive is used.

Abstract: A dispensing closure consisting of a cap with a cavity defined in its upper surface, and a spout to fit within the cavity. The spout has an enlarged base, and a central passage extending through the base and the remainder of the spout. Aligned trunnions are formed on the opposite sides of the base of the spout. An opening in the cap allows communication between the container upon which the cap is seated and the central passage in the spout. A pair of standards are integrally molded within the cavity in the cap, and one standard is situated on each side of the opening. A U-shaped bearing, with a slightly restricted opening, is located at the upper end of each standard and spaced fingers define the entrance into each bearing. The trunnions are forced downwardly into the opening in each bearing. The fingers deform momentarily to accept the trunnions and return to their unstressed condition to capture same, thus securing the spout to the cap and exerting a downwardly directed force upon the spout.

Abstract: A method and apparatus for dispensing a substance such as a hydrophylic polymer into a soil to minimize the need for repeated irrigation, plant feeding or the like. A trailer supports a mixing tank within which the polymer and a liquid such as water are continuously agitated. The mixture, in a liquid form, is sent through a pump to an outlet having a plurality of apertures communicating with the tank via a manifold. A valve operatively conditions the throughput of the water and polymer so that a series of high pressure pulses exit the outlet and cause slugs of liquid to contact the ground at a sufficient velocity that the slugs penetrate the soil and deform under the surface of the soil. The rapid opening and closing of the valve when used with the outlet's apertures can provide a distribution pattern in the soil which is substantially uniform and minimizes the likelihood of disproportionate polymer infusion in the ground which would otherwise cause non-uniformly swelling.

Abstract: A resealable plastic closure formed of one piece of plastic material includes a swivelable diaphragm to allow a hinged spout to pivot between an upright dispensing position and a down closed position. To permit easier operation in closures containing diaphragms in small sizes, the diaphragm is divided by a crease, hinging the two section, and one diaphragm section is invertible and the other diaphragm section is pliable, deformable. Improved side latches for the spout are provided by flexible latch member supporting wall that may flex into an adjacent cavity on the underside of the closure base. The fabrication of those side latches is enhanced in a process that withdraws one tool to create a void behind the latch member supporting walls so that the other tool, which forms the latch member, may be withdrawn without damaging the member by forcing the walls to flex laterally as the second tool is withdrawn.

Abstract: A closure includes a capping part (1), which is attachable to a container, in which a form-stable floor wall (9) has a sealing apparatus (11) with a sealing cone (13) is held to the rest of the capping part by means of a flexible wall area so that the sealing cone can be brought into and out of a sealing engagement relationship with a mouth opening (5) of the container. Measures are provided, for example in the form of inversions of a flexible wall area (12), to hold the sealing apparatus in end positions corresponding to open and closed positions of the sealing apparatus. In the end positions the sealing apparatus (11) can be moved by hand via an integral hand-manipulation portion (15). A pour spout (16) can be formed on the flexible wall area (12) so that it experiences a swinging upon movement of the sealing apparatus (11) between the closing and opening position corresponding to the respective positions of the flexible wall area.

Abstract: A tamper indicating seal for a dispensing closure that is secured to a container to discharge the contents thereof. Closure induces a depending skirt, and a planar top surface, with a cavity defined within the top surface. A spout is located within the cavity, and may be pivoted between a horizontal, closed position and a vertical, open position. The unique seal comprises a thin plastic tab, with frangible members depending below, to secure the tab to the upper surface of the spout in an overlying relationship. The frangible members are durable enough to form an effective seal, yet weak enough to fracture when the spout is pivoted toward its vertical position. The tab, when severed from the spout, is used as a proof of purchase indicator. The absence of the seal clearly indicates to the user that someone has attempted to gain access to the contents of the container.
