Definitions

  • a dispensing tap may include a body having a peripheral skirt for connection to the neck of a container, a dispensing head, and a throat connecting the body to the dispensing head which provides a flow path from the body to the dispensing head.
  • the dispensing head may further include a dispensing outlet or mouth.
  • a shut off valve may be configured for sealing engagement with the mouth of the dispensing head, and a piston may be axially guided within the dispensing head.
  • the piston may include a peripheral seal slidably engaged with an interior surface of the dispensing head.
  • a valve stem extends from the piston and a terminal end thereof may be coupled to the shut off valve.
  • the spring may comprise a slotted tubular spring element formed from a tensile polymer.
  • the slotted tubular spring element may be captured between opposing loading cones formed on the piston and the dispensing head.
  • the vent may include a ball valve disposed within an interior of the body, or the ball valve may be located at the terminal end of an extension tube which would extend into the interior of the container when mounted.
  • FIG. 1 illustrates a hquid container and a dispensing tap in accordance with an exemplary embodiment of the invention
  • Fig. 8 illustrates a cross-sectional view thereof taken along hne 8-8 of Fig. 2;
  • FIG. 9 illustrates a perspective view thereof with the actuator piston depressed for dispensing
  • FIGs. 16 and 17 illustrate closed and open cross-sectional views of yet another self-venting structure in accordance with some embodiments of the invention
  • Fig. 19 illustrates a cross-section view thereof taken along line 19-19 of Fig. 18;
  • Fig. 20 illustrates an exploded perspective view thereof
  • Fig. 21 illustrates a perspective view of the dispensing head thereof
  • Fig. 23 illustrates a perspective view of a further exemplary embodiment of a dispensing tap including finger holds and a lever actuator;
  • Fig. 30 illustrates a perspective view thereof with the lever actuator depressed for dispensing
  • the piston 118 may be selectively actuable or depressible (see arrows in Figs. 9-10) by a button structure 130 which is integrated with the upper surface of the piston 118.
  • the piston 118 may be actuated between a normally closed position (See Figs. 2-8) wherein the shut off valve 116 is seated within the mouth 114, and an open position (See Figs. 9 and 10) wherein the shut off valve 116 is disengaged from the mouth 114.
  • the button structure 130 may be integrally formed with the piston 118 or may be molded separately and attached.
  • the dispensing head 108 may include external finger holds 132 to facilitate depression of the actuator button 130 connected to the piston 118.
  • the exemplary finger holds 132 extend radially outwardly from the exterior surface of the dispensing head 108 and facihtate the depression of the button actuator 130 with the users thumb by providing a leverage point for the user’s index and middle fingers straddling the dispensing head 108.
  • a spring 134 may be captured between the piston 118 and the dispensing head 108 normally biasing the piston 118 and shut off valve 116 to the closed position.
  • the spring 134 may comprise a slotted tubular spring element formed from a tensile polymer.
  • the slotted tubular spring element 134 may be captured between opposing loading cones 136, 138 formed on the piston 118 and the dispensing head 108.
  • the slotted tubular spring element 134 is cylindrical in shape and the loading cones 136, 138 are generally conical in shape.
  • the exemplary embodiments of the loading cones include a first frustoconical pre-loading wall section having a steeper wall angle greater than 11 degrees, and a second frustoconical primary loading wall section having a shallower wall angle of less than 11 degrees.
  • the spring 134 may comprise a conventional coil spring 134A captured between the piston 118 and dispensing head 108.
  • the upper and lower loading cones 136, 138 act as spring guides.
  • an atmospheric vent 140 may be provided in communication with an interior of the body 102 and in some embodiments, the vent 140 may be opened and closed with movement of the piston 118 and shut off valve 116. As best seen in Figs. 8 and 10, a vent 140 extends between an interior surface of the dispensing head 108 and the interior of the body 108.
  • the vent 140 may include ball valve 142 disposed on the interior of the body 108 to prevent fluid from escaping in at rest conditions.
  • the peripheral piston seal 120 is configured with a v-shaped multiple lip (chevron) seal for engagement with the vent opening formed on the interior surface of the dispensing head.
  • the peripheral chevron seal 120 may be engaged with, or overlie, the vent opening when the piston is in the closed position (See Fig. 8) and may be disengaged from the vent opening (See Fig. 10) when the piston is in the open position.
  • This arrangement creates a self -venting system wherein the vent 140 and the shut off valve 116 are opened and closed simultaneously.
  • some embodiments 200 of the invention may exclude the ball valve structure and rely on only the chevron seal 220 to prevent fluid from escaping in at rest conditions.
  • the embodiment 200 is structurally and functionally similar to tap 100, and includes body 202, dispensing head 208, throat 210, mouth 214, shut off valve 216, piston 218, button 230 and spring 234.
  • the diameter (P D ) of the peripheral seal 120 on the piston 118 is larger than the diameter (Vb) of the shut off valve 116.
  • Vb diameter of the shut off valve 116.
  • normal fluid head pressure is greater on the piston seal 120 than the shut off valve 116, and naturally exerts a higher force in the closed direction to keep the shut off valve 116 closed.
  • the arrangement further works advantageously when external pressure is exerted on the container 900 to prevent leaks from the shut off valve 116.
  • the configuration is visible in Figs. 1-10 which show the upper piston portion of the dispensing head having a slightly larger diameter than the lower mouth portion. However, the features are best illustrated in Fig. 11 showing the two different internal diameters.
  • some embodiments 600 of the invention may include an actuator lever 670 which engages with the top of the piston.
  • the embodiment is similar in internal functional structure as the previous embodiments 100, 200, 500, with the exception of the lever 670 and finger hold structures 632.
  • the tap 600 includes a body 602, dispensing head 608, throat 610, mouth 614, shut off valve 616, piston 618, seal 620, valve stem 622, button 630, spring 634, vent 640 and ball valve 642.
  • the 670 lever may be L-shaped and pivotably anchored at one end 672 on the exterior of the body 602.

Abstract

L'invention concerne un robinet de distribution (700) pour liquides, comprenant un corps (702) relié au goulot d'un récipient (900), une tête de distribution (708) munie d'un orifice de sortie ou ouverture (714), et un étranglement (710) qui relie le corps à la tête de distribution. Une vanne d'arrêt (716) est conçue pour venir en contact d'étanchéité avec l'ouverture de la tête de distribution, et un piston (718) est guidé dans le sens axial à l'intérieur de la tête de distribution. Le piston comprend un joint d'étanchéité périphérique (720) en prise coulissante avec une surface intérieure de la tête de distribution, et une tige de vanne (722) couplée à la vanne d'arrêt. Le piston peut être actionné sélectivement entre une position normalement fermée et une position ouverte. Un évent (740) est en communication avec l'intérieur du corps et l'évent est ouvert et fermé par le mouvement du piston et de la vanne d'arrêt.
