Definitions

  • the present invention is intended to provide an improved combined pouring spout and piercing device which removes the mentioned disadvantages and also facilitates the piercing of container walls, achieving a correctly shaped pierced hole conforming with the thread core.
  • the hole is slit open radially repeatedly at its edge.
  • the pierced material curls radially away on the side of the container wall remote from the piercing.
  • a round pierced hole adapted to the corediameter is formed into which the threads can be introduced and screwed with absolute reliability until a packing ring seated on the threaded shank presses firmly against the outer surface of the bag.
  • the pouring spout of the invention provided with an internal, fluid-conducting conduit, includes a threaded shank, a housing with a positioning surface, and a piercing head.
  • the positioning surface and the piercing head are arranged at opposite ends of the threaded shank.
  • the positioning surface is in abutment with a packing ring mounted on the threaded shank.
  • the threads are deep with small pitch and small flank angle. They commence with a greatly downwardly swept thread introduction noseon one of several cutting edges of the piercing ribs.
  • the threads terminate in the packing ring region at the positioning surface.
  • the piercing ribs are arranged more or less radially and rise away from the piercing tip at an acute angle, i.e., an angle less than 90".
  • FIG. 1 shows a pouring spout in elevation.
  • FIG. 2 shows a plan view thereof without closure plug.
  • FIG. 3 shows a cross section of the piercing tip along the section line H in FIG. 1.
  • FIG. 4 shows the pouring spout placed upon a container, partially in axial section.
  • FIG. 5 shows a part of FIG. 4 in enlarged fashion and partially in cross section.
  • the illustrated pouring spout housing 1 possesses an outer periphery 3 provided with raised portions 2 of handgrip form.
  • the fluid-conducting conduit 4 is closable with a closure plug 5, and at its pouring edge 6 is inclined obliquely outwards to render drip-free pouring possible.
  • a positioning surface 7 delimits the lower end of the housing 1, from which surface an externally threaded, tubular shank 8 with V-threading 9 commences.
  • Connected with the lower end of the threaded shank is alternately ribbed and fluted piercing head 20, which terminates in a piercing tip 10.
  • the ribs 14 of piercing head 20 protrude substantially radially from the axis of the spout and have cutting edges 13 on their outer edges. As illustrated in FIG.
  • the piercing ribs rise from the piercing tip 10 at an acute angle.
  • the ribs attain a continuously greater protrusion from the axis of the spout with increasing distance from the piercing tip, until a maximum protrusion is attained. It is preferred to make the maximum protrusion equal to the thread root radius.
  • Packing ring 11 is mounted around the threads 9 and lies in abutment with the positioning surface 7.
  • the inner diameter of ring 11 is less than the crest diameter of the threads, as shown in FIG. 5.
  • This ring is made of a resilient material, such as rubber.
  • the shank 8 and its threads 9 terminate at their lower end with a downwardly swept thread-introduction nose 12.
  • the crest of this nose 12 recedes radially from its normal radial position at 21 into coincidence with the outer edge of its rib 14 at point 22. In its downward sweep into coincidence with the outer edge of the rib, the nose 12 never curves so rapidly that its surface becomes vertical.
  • the angle A in FIG. 4, formed between the vertical and the extension of the crest line at point 22, is always greater than 0.
  • the preferred angle shown is approximately 15. Angle A greater than 0 assures that the wall of the container will slide along the thread nose when the spout is given a screw movement after the container has been pierced with piercing head 20.
  • the piercing head In operation, the piercing head is forced through the wall of a container.
  • the ribs 14, by means of their cutting edges 13, form slots in the container, and the resulting sectors are later automatically curled over to form a hole exactly fitting the roots of the threads 9.
  • Bite is the amount of container wall pinched between the packing ring 11 and the upper thread flanks, as measured in the radial direction from the axis. If the particular bite chosen is too small, the unsupported, inner edge of the hold will collapse under pinching pressure.
  • a thread depth of at least 2 mm. and a flank angle between 15 and 25 are used.
  • the diameter of the threaded shank can be varied to obtain required pitch, thread depth and flank angle for a particular container wall thickness.
  • the threads must always be sufficiently coarse to accept the wall thickness of the particular container. Particular cases of given wall thicknesses are readily designable by one familiar with .the skills of mechanical engineering, given the desired m'ediately below the positioning surface ,7 (FIG. 5). This perniits secure tightening without fear of excessive rotation.
  • the present invention is useful for containers containing s'olid fluids, such as granulated sugar, which is flowable, as .well as for liquid fluids.
  • “Lower” and upper are with reference to FIG. 1, the uppermost part being the closure plug 5, the lowest point being the piercing tip 10.
  • a combined pouring spout and piercing device for penetrating a thin wall container and for drawing off a fluid from within said container, comprising an elongated, fluted and ribbed piercing head, the ribs having cutting edges thereon converging'to a sharp point at one end of the head and achieving continuously greater transverse protrusion progressively towards the other end of the head until a predetermined maximum protrusion is attained, the sharp point serving to puncture and penetrate the thin wall container when thrust therethrough, the ribs rising radially from the sharp point at an angle of less than 90, an externally threaded tubular shank aligned with and connected to the piercing head at its end of greatest rib protrusion, the root radius of the threads substantially equaling the predetermined maximum protrusion of the ribs, the threads including a downwardly swept nose means to engage the threads with the container wall, the nose terminating at one of said cutting edges, an elongated housing aligned with and connected to the
  • a device wherein the threads have a flank angle of between 15 to 25 and a depth of at least 2 millimeters.
  • a device wherein the ribs divide the conduit in its lower part into several individual passages.
  • a device according .to claim 1, wherein the packing ring consists of resilient material yielding to a positioning pressure and the packing ring is threaded onto the threads.
  • a device wherein the outer periphery of the housing possesses raised means to provide a hand grip and further includes a closure plug inserted in the conduit at said opposite end of the housing.
