Definitions

  • the present invention relates generally to dispensing containers and more specifically to dispensing cap constructions enabling accurately measured amounts of container contents (in granular particulate powdered or liquid form) to be dispensed from the cap
  • Dispensing containers are of course well know n and are used in man ⁇ different industries for many different purposes
  • One such use is in the food industry, and a specific example includes jars and other similar containers which contain solid foods (such as spices) in paniculate granular or powder-like form
  • jars and other similar containers which contain solid foods (such as spices) in paniculate granular or powder-like form
  • a measu ⁇ ng spoon or separate measuring cup is utilized in coniunction with the ]ar or container when accurate amounts are to be obtained
  • the present invention eliminates the need for measuring spoons or cups by providing a hollow cap, which serves as its own measu ⁇ ng device, for use with an otherwise conventional container While the incorporation of a measuring function into a container/cap construction for the discharge of desired amounts of the container contents is not new (see for example, U S Patent Nos 1,802,284, 2,804, 103, 3,860, 1 1 1 , 4,613,057 and 4,635,828), the present invention provides an improved and simplified structure for accomplishing this result More recently, improved dispensing type measuring caps or closures have been disclosed in commonly owned U S patent application Se ⁇ al No 08/288,896 filed August 10, 1994 and in commonly owned U S Patent No 5,465 871

  • the skirt incorporates an inverted, partial dome-like (or partial upright bowl-shaped) weir panel which, along with a portion of the pivotable top, form a measu ⁇ ng chamber into which measured amounts of container contents may be poured
  • This weir panel also serves as a weir dam to prevent excess amounts of container contents from spilling over the edge of the panel and into the measu ⁇ ng chamber
  • the weir panel edge lies parallel to a diametrical center line extending across the top of the cap, (and perpendicular to the longitudinal vertical axis of the cap) so that an adjacent weir opening into the chamber is semi-circular in shape
  • the pivotable flip top includes a panel hingedly secured to the depending skirt along a hinge axis which extends along the same diametrical center line
  • one half of the flip top panel overlies the measuring chamber, while the other half of the flip top panel overlies the weir opening, the two half portions (also referred to herein as the dispensing panel portion and the push panel portion) separated by the hinge axis
  • a semi-circular flip top stop surface underlies the push panel portion, sloping downwardly from the hinge axis to the depending skirt
  • This stop surface terminates at the hinge axis in a seat or cradle in which a hinge axis nb on the underside of the flip top is received
  • a living leaf-type spring is hinged to the push panel portion of the flip top and is interposed between the push panel portion and the sloped flip top stop surface In this way, the flip top panel is resiliently mounted such that when the push panel
  • an internal thread (or other suitable means) is provided for enabling conventional securement of the cap to the threaded upper end of a container or jar
  • diametrically opposed pins or protections aligned with the hinge axis, extend from the flip top panel and snap into mating dimples provided at the upper end of the depending skirt so as to hold the flip top panel in place
  • the semi-circular pe ⁇ pheral portion of the measuring chamber, at the uppermost portion of the depending skirt may be provided with a snap-type engagement surfaces for interaction with the peripheral edge ofthe dispensing panel portion of the flip top panel, to thereby enable sealing engagement when the flip top panel is rocked to a closed position
  • the integral leaf spring may be omitted such that the flip top panel must be moved manually from the open to the closed position
  • annular ring spaced radially inwardly of (and concentric with) the depending skirt, seats on the upper annular nm of the container or jar to prevent any egress of container contents and also to serve as a stop limit to the screw threaded action between the threads on the cap and the threads on the container
  • a substantially rectangularly shaped flip top is mounted for pivoting movement within a similarlv shaped opening formed in the top surface of the cap
  • the hinge axis of the flip top as well as the weir edge of the internal w en panel are vertically aligned with each other, but laterally offset from a parallel, diametrical center line through the cap
  • the above described rectangular flip top incorporates a measuring chamber seal panel or shut-off blade which seals the weir aperture against further transfer of material to the measuring chamber when the flip top is opened and the measured amount dispensed from the chamber
  • a further improved measuring/dispensing closure which also incorporates a flip top cap and a built-in shut-off blade
  • a plastic measuring/dispensing closure includes a pivotable flip top which is seated on a dome-like upper portion of a peripheral skirt The dome-like portion tapers upwardly and inwardly to a round opening defined by an upstanding annular nm, and the flip top is arranged to seal the opening in a closed position, and to permit dispensing of measured amounts of contents through the opening when in the closed position Located within the dispensing opening, there is an inverted, dome-shaped chamber wall, or weir dam panel, formed with a horizontal chordal edge so that a weir opening is formed between the chordal edge and the peripheral surface of the dispensing opening
  • a measuring chamber is formed by reason ofthe cooperation of the weir dam panel, the underside of the cap portion of the flip top, and the peripheral portion of the dispensing opening formed in the dome-like portion of the closure skirt
  • the underside of the flip top is formed with a shut-off blade which has a cur ature generally similar to that of the cap portion of the flip top
  • This shut-off blade extends vertically downwardly from the underside of the cap portion and is shaped and sized to engage the edge of the weir dam panel when the flip top is moved to an open position upon the exertion of force or pressure on the press flange portion of the flip top
  • the user may transfer a desired amount of contents from the body of the container into the measuring chamber After the desired amount has been transferred, the user may then open the flip top and, at the same time, cause the shut-off blade to engage the chordal edge of the weir dam panel so that the amount dispensed from the closure is exactly that amount which has been transferred into the measuring chamber
  • the user need not be concerned that additional contents will flow from the container into the measuring chamber when the container is lifted to facilitate dispensing contents from the measuring chamber

Abstract

L'invention concerne un capuchon distributeur doseur (10) destiné à un récipient (C), pourvu d'une paroi latérale périphérique (14) et d'un volet pivotant (12) faisant office de couvercle, soutenu par la paroi latérale périphérique de façon à pouvoir basculer autour d'un axe d'articulation qui sépare une partie poussoir (16) d'une partie de distribution du couvercle basculant. Une chambre de dosage (58) est formée dans une zone entourée par la paroi latérale périphérique, se trouvant sous la partie de distribution du couvercle. Cette chambre de dosage est définie par une partie de la paroi latérale périphérique, par la partie de distribution du couvercle et par une partie de déversement (50) formant un angle, s'étendant, depuis la paroi latérale périphérique, vers le bas et vers l'intérieur et se terminant par un bord de déversement (52) qui est sensiblement aligné, dans le sens vertical, avec l'axe d'articulation, ce qui crée une ouverture de déversement (53) permettant l'entrée dans la chambre. Le couvercle pivotant comporte un volet d'obturation (34) qui s'étend vers le bas et vient en contact avec le bord de la partie de déversement.
