Definitions

  • the present invention relates to a nozzle comprising a hollow circular cylindrical nozzle main body having an externally threaded portion screwed into an internally threaded member and a strainer held by a strainer holder which has a circular aperture in its upper portion as known from FR-A-2.098.782.
  • the strainer has been accomodated in the round tubular strainer holder from which a part is formed by the internally threaded member.
  • nozzles incorporating a strainer in the forward end there is a need to replace or clean the strainer e.g. when the nozzle is to be used for a different kind of liquid.
  • the strainer it is desired that the strainer be easy to remove and install, while the strainer mount portion should be free of leaks.
  • a nozzle having a rectangular end for giving an increased effective area, whilst the nozzle includes a strainer which is easy to mount and remove and which is mounted in place without any likelihood of leakage from the mount portion.
  • the internally threaded member is provided with a pair of outwardly open grooves, one on each of opposite sides of its lower end, for reception of respective projections on the inner surface of the upper end of a rectangular tubular member which houses the strainer and strainer holder, a projecting edge of the nozzle main body fitting in the circular aperture of the strainer holder.
  • the rectangular tubular member has an inner periphery and an outer periphery which are square in horizontal section.
  • the outer periphery of the tubular member is slightly tapered.
  • the upper-lower relation is determined with reference to fig. 1.
  • the upper portion of the nozzle is positioned at the upper end of the drawing, and the lower portion of the nozzle is positioned at the lower end of the drawing.
  • a nozzle embodying the invention has a rectangular forward end portion which is in the form of a rectangular tubular member 1.
  • the member 1 has an inner periphery and an outer periphery which are square in horizontal section. The outer periphery is slightly tapered towards its lower end.
  • a pair of opposed upper extensions 2 is formed on opposite sides of the upper end of the tubular member 1.
  • a pair of horizontal inward projections 3 is formed on the inner opposed surfaces of the pair of upper extensions 2 at their upper ends.
  • An inward bent edge 4 is formed at the lower end of the tubular member 1 inside thereof. By the inward bent edge 4, a strainer 5 comprising a plurality of sheets is horizontally retained in the interior of the rectangular tubular member 1 at its lower end.
  • the strainer 5 is held in place by an inverted box-shaped strainer holder 6, which is formed with a circular aperture 8 in the center of its top wall 7.
  • the holder has in inner conical surface extending from the top wall 7 downward with an increasing diameter.
  • An internally threaded member 10 has an outer periphery square in horizontal section and having the same size as the upper end of the outer periphery of the. rectangular tubular member 1.
  • the member 10 is formed in each of opposite sides of its lower end with an outwardly open horizontal groove 11.
  • the internally threaded member 10 has a circular inner periphery at its lower portion.
  • the pair of inward projections 3 is fitted in the pair of grooves 11, whereby the internally threaded member-1.0 is attached to the rectangular tubular member 1.
  • a hollow cylindrical nozzle main body 12 is provided at its lower end with a projecting edge 13 of reduced outside diameter.
  • the main body 12 has an intermediate portion 14 of larger outside diameter on the upper side of the edge 13, and an externally threaded portion 15 on the upper side of the portion 14.
  • the projecting edge 13 is formed in its outer periphery with an annular groove 16 having an O-ring 17 fitted therein.
  • the projecting edge 13 is fitted in the circular aperture 8, and the intermediate portion 14 in the lower portion of the internally threaded member 10, with the externally threaded portion 15 screwed in the internally threaded member 10.
  • the projecting edge 13 fitting in the circular aperture 8 serves as a stopper for preventing the projections 3 from slidingly moving relative to the grooved portions 11.
  • the nozzle of the invention has a rectangular end portion, containers having a rectangular opening can be filled with a liquid quickly within a shortened period of time by inserting the nozzle end' portion into the container. Moreover, the strainer is easily removable from the nozzle main body for replacement or cleaning, while the nozzle mount portion is made completely liquid-tight against leakage.
