Definitions

  • ABSTRACT A vented pouring spout formed of synthetic plastics material adapted to be retracted in stored position within a container opening and pulled up to extended pouring position for dispensing of the container contents.
  • the spout is formed at its inner end with venting means for permitting the entry of air within the container through the pouring spout simultaneously with the liquid dispensing.
  • the invention presents an effective solution to the problem in providing a new and novel pouring spout designed to simultaneously dispense a container contents and vent the container interior to the surrounding atmosphere.
  • the spout has a simple unitary construction which facilitates rapid, gurgle free pouring while permitting the entry of atmospheric air through the spout into communication with the container interior. This is accomplished by forming radially opening air passages about the circumference of the spout base in conjunction with spout supporting means.
  • An annular baffle is also provided at the innermost end of the spout for separating the dispensing liquid flow from the incoming air supply.
  • Another object is to provide a one piece self-venting pouring spout economically molded of synthetic plastics material.
  • a further object is to provide a pull up pouring spout incorporating container venting means in conjunction with supporting means for rigidly retaining the spout in pouring position.
  • FIG. 1 is a perspective view of the vented pouring spout of the invention
  • FIG. 2 is a part elevational part sectional view of pouring spout in retracted stored position within a closure nozzle
  • FIG. 3 is a view similar to FIG. 2, but showing the nozzle inserted in a container with the spout in extended pouring and venting position;
  • FIG. 4 is an enlarged fragmentary view showing the engagement of the spout base with the nozzle.
  • FIG. 5 is a bottom plan view of the pouring spout.
  • the vented spout l molded of synthetic plastic material, has a cylindrical body 2 terminating at its upper end in a circumferential lip 3.
  • a semi-circular lifting bail 4 is hingedly connected to the lip 3 at diametically opposed points 5.
  • the cylindrical spout body has an outwardly tapered portion 6 terminating in a lower edge 7.
  • the baffle 10 is provided with a central aperture 11 and is axially spaced from the lower edge 7 so as to form four radially directed openings 12.
  • the spout 1 is retained within a closure fitting 13, also molded of synthetic plastic material, comprising a nozzle 14 having an internal cylindrical throat 15.
  • the lower portion of the throat 15 has a reduced diameter as indicated at 16 forming a spout retaining ledge 17, clearly seen in FIG. 2.
  • a container wall engaging surface 18 is formed along the lower exterior of the nozzle throat 15.
  • a circumferentially enlarged cap receiving bead 19 is formed about the upper end of the nozzle 14.
  • the uppermost end of the nozzle throat 15 is closed off by a tear-out sealing diaphragm 20 having an integrally formed ring pull 21 for tearing.
  • a captive snap cap 22 is connected by a strap 23 to the nozzle 14 for frictional engagement over the nozzle bead 19.
  • the fully assembled closure fitting is pressed into a closure receiving opening 24 formed in the head 25 of a container 26.
  • the container opening 24 bites into the nozzle surface 18 forming a leakproof joint.
  • the container In operation, the container is supplied to the filler who performs the filling operation through the opening 24 and presses the nozzle 13 into the opening, sealing the containerfor shipment.
  • the end user opens the snap cap 22, and tears away the sealing diaphragm 21 by means of the ring pull 21, exposing the readily grasped spout bail 4.
  • the spout 1 is then pulled up to extended pouring position.
  • the pouring action of the spout is illustrated in FIG. 3 wherein it can be seen that the container contents are dispensed through the central aperture 11 in the spout baffle 10 simultaneously with the entry of air into the spout and through the openings 12.
  • the baffle 10 effectively separates the outgoing fluid from the incoming air with the radially directed openings 12 providing a direct, unimpeded path for air to communicate with the interior of the container.
  • the openings 12 are so formed in conjunction with the spout supporting feet 8 as to minimize the spout extension within the container during pouring to facilitate complete emptying of the container.
  • a self-venting pouring spout adapted to be pulled up from a retracted stored position within a container to an extended pouring position comprising a substantially cylindrical upper body portion, a circumferential lip at the upper end of said body portion for supporting said spout in retracted position, a lower body portion terminating in a spout base having a lower edge, an annular baffle axially spaced from said spout lower edge and connected thereto by a plurality of axially extending feet forming a series of radially directed openings therebetween circumferentially spaced about said spout base and a central aperture located in said baffle whereby liquid is dispensed through said central aperture while venting air is simultaneously introduced through said spout in communication with one or more of said radial openings.
  • a fluid dispensing closure fitting for containers comprising an annular dispensing nozzle including a cylindrical throat terminating in a lowermost free edge, a container wall engaging surface surrounding said nozzle throat, closure engaging means formed on the upper end of said nozzle, spout supporting means formed along said nozzle throat, a self-venting pouring spout adapted to be pulled up from a retracted stored position within a container to an extended pouring position, said spout including a substantially cylindrical upper body portion, means formed on the upper end of said body portion for engaging said spout supporting means along said throat with said spout in retracted stored position, a lower body portion terminating in a spout base, having an annular baffle formed with an axially directed liquid dispensing aperture, said spout base including circumferentially spaced means adapted to engage said nozzle throat lowermost free edge for retaining said spout in extended pouring position within said nozzle, and radially directed passages formed in said spout base intermediate
