Closure Type Patents (Class 222/528)
  • Patent number: 4216880
    Abstract: Collaspsible spout for dispensing fluent materials from containers such as used for various liquids and/or granular or powdered products. The container includes a top panel provided with an aperture. A lever is pivotally disposed to selectively open and close the aperture and carries on its underside a pliant sleeve sealed at one end about the periphery of the aperture and with its other end adapted to be opened adjacent the outer end of the pivotable lever. In closed position the lever in the form of a flat strip lies generally flush atop the container and for opening the container the lever is pivoted outwardly from the top of the container, thereby automatically extending and unfolding the pliant tubular sleeve. The aperture is reclosable by swinging the strip back against the top of the container. In an alternate embodiment, the lever is disposed within the pliant sleeve and includes a cutting tip at its inner end for cutting the aperture as the lever is pivoted upwardly.

  • Patent number: 4214674
    Abstract: A toy water gun assembly capable of ejecting water in bursts or in a continuous manner, is disclosed. A separate, pressurizable water container is connected by a flexible hose, to a pistal shaped member. A section of the flexible hose, mounted in the pistol shaped member, is continuously clamped by a lever. A spring biases the lever to prevent the release of a water stream through a nozzle which is mounted on the front of the pistol shaped member. A trigger member having a pointed pawl pivotably mounted thereto, is operatively connected to the lever. An initial movement of the pawl member caused by a quick pull on the trigger member momentarily removes the lever from its position clamping the hose. Additional movement of the pawl causes it to slide off the lever, thereby allowing the lever to return to its regular position wherein the hose is clamped.

  • Patent number: 4196030
    Abstract: A method of making an extruded construction for bags, comprising forming in an integral one piece plastic extrusion a flexible collapsibly foldable thin wall closure web area joined at its opposite ends to proximal ends of a pair of pull flange portions of substantial length, and as part of the extrusion forming separable resiliently flexible interlocking complementary fastener profiles adjacent to said proximal ends; collapsibly folding the closure web area away from the flange portions and the profiles, coupling the fastener profiles together, and enveloping the collapsibly folded closure web area within bag body side wall panels having end parts joined to the extrusion adjacent to the profiles. The side wall panels may be extruded integrally with the closure web area, the flange portions and the fastener profiles; or the side wall panels may be separately formed and sealed to the collapsibly folded closure web area or the flange portions adjacent to the profiles.

  • Patent number: 4150778
    Abstract: A carton structure fabricated from a single blank of paperboard or similar foldable sheet material is characterized by a tubular body having hingedly connected sidewalls which are initially folded and connected in flattened relation, with panels at opposite ends of the blank overlying each other and constituting a body sidewall in which the outer wall panel has a tear tab arranged to be torn loose and hinged outwardly when the carton is set up so as to form a dispensing opening while the inner wall panel has an integral portion in which a hinged spout forming member is cut and positioned so that a portion thereof which is secured to the tear tab will be pulled into the dispensing opening and form therein a pouring spout upon outward movement of the tear tab. This application is a continuation-in-part of Ser. No. 824,351, filed Aug. 15, 1977, is now abandoned.

  • Patent number: 4148155
    Abstract: A system and apparatus for growing plants in a nutrient solution while supported in an inert medium contained in a pot container includes a nutrient solution reservoir and automatic feeder apparatus for maintaining a predetermined level of nutrient solution in the container including a tube member connected to the reservoir having an open end carried a predetermined distance above the container bottom for dispensing the solution. An air vent communicates with the tube member allowing air to enter the reservoir in response to the level of nutrient solution in the container falling below the open end of the tube member as the solution is drawn by capillary action through the media into the roots. The nutrient solution flows into the container until the open end of the feeder tube is covered so as to continuously maintain the level of nutrient solution. An overflow opening drains excess liquid from the pot preventing overwatering and stagnation when used outdoors.

  • Patent number: 4119263
    Abstract: A bulk container for bottom unloading having a novel deformable bottom feature. The novel bottom feature comprises a plurality of scorelines being formed on the central portion of the bottom with the scorelines serving to weaken the bottom portion so that it deforms into a generally funnel shape from the weight of the product positioned within the container. The product is then removed from the container through an opening in the deformed bottom with the flow from the container being controlled by a slide plate if flow control is desired by the user of the container.

  • Patent number: 4103887
    Abstract: Portable barbell apparatus is disclosed comprising a collapsible enclosure made of a synthetic polymeric material. The enclosure has a base and an aperture for filling the enclosure. The center of gravity of the enclosure is between the aperture and the base, an opening being provided in the enclosure for receiving the end of a weight supporting bar, the opening being positioned in between the center of gravity and the aperture. This arrangement allows for the positioning of a pair of the enclosures on either end of a weight supporting bar after which the enclosures may be filled with water, sand or other particulate material so that the assembly may be employed as a barbell. When not in use, the enclosures may be removed from the weight supporting bar, emptied and conveniently transported and/or stored. The aperture comprises a slit and has a resilient member extending around the periphery thereof to resiliently bias the slit to a closed position.

  • Patent number: 4039118
    Abstract: An automatic dispensing container for containing and dispensing granular material is disclosed which may be constructed from a single piece of sheet material to form a container having an internal ramp partition. The ramp serves to direct the material by force of gravity toward and through a dispensing orifice having a configuration which impedes the free flow of material. The rate at which the material is dispensed is controlled by a structure integral with the ramp which, when moved, serves to assist the flow of material through the orifice.
