Definitions

  • This invention is concerned with apparatus to allow the discharge of liquid from a container.
  • the container commonly includes a side discharge port near the bottom of one container side and a discharge means is provided to allow the contents to flow from the liner bag through the discharge means.
  • the liner bag needs to be punctured in a manner which prevents the plastic bag adjacent the puncture entering the discharge means.
  • the cutter teeth sever all but a portion of the membrane which covers the bore of the nozzle and in so doing forms a discharge opening and a flap which remains connected to the liner by the unsevered membrane portion.
  • the flap is prevented from entering the discharge opening created by the cutter and is held out of alignment with the discharge opening by a flap retainer which projects through the discharge opening into the interior of the liner bag.
  • the flap retainer also prevents the bag around the discharge opening entering the discharge opening.
  • the present invention achieves the above conditions by using a cutter which is rotated to perform the cutting operation as distinct from the known arrangement where the movement of the cutter is purely linear.
  • the invention can be said to provide a bag puncturing means which comprises a cutter support which has a threaded portion at one end of the support whereby the cutter support is can be engaged with a threaded nozzle of a bag, said nozzle has a bore closed by a cutable membrane to be punctured by said bag puncturing means, a passageway through the cutter support, a compression spring housed in the passageway, said spring having a first end disposed within said passageway whereby the spring is held captive to the support and a length such that when the spring is uncompressed a portion of said spring which terminates in a second spring end projects from the passageway beyond said one end of the support, a membrane cutting means connected to said support so as to be rotatable with said support, said membrane cutting means includes a portion which will always project beyond said one end of said support.
  • Fig.l is a side view of a first form of spring mounted cutter according to the invention.
  • Fig.2 is a side view of a second form of spring mounted cutter according to the invention.
  • Fig.3 is a side view of a third form of spring mounted cutter according to the invention.
  • Fig.4 is a side view of a fourth form of spring mounted cutter according to the invention.
  • Fig.5 is a side view of a fifth form of spring mounted cutter according to the invention.
  • Fig.6 is a side view of a sixth form of spring mounted cutter according to the invention.
  • Fig.7 is a side view of a cutter and spring combination according to the invention.
  • Fig.8 is a front view of a blade cutter according to the invention.
  • Fig 9 is an edge view of the cutter shown in Fig.8,
  • Fig.10 illustrates the cutter of Figs.8 and 9 as initially mounted in a bag nozzle prior to bag puncturing taking place
  • Fig.11 is a view similar to Fig.10 where the cutter of that arrangement is commencing to cut the membrane of the liner bag to form a discharge opening, and Fig.12 illustrates the situation after the liner bag membrane has been punctured.
  • Fig.l shows a compression spring 1 which has a constant diameter for most of its length and has a conical leading end 2 and a clamping coil 3 at its other end.
  • the clamping coil 3 has a greater diameter than the body of the spring 1.
  • a cutter 4 which moves linearly with the compression and decompression of the spring 1 in a bag puncturing operation is welded to the spring. The position of the cutter 4 is such that even when the spring is substantially compressed, as will be clear from the following description, the cutting end 24 of the cutter 4 will always be in a position to engage the membrane of the liner bag to be punctured.
  • Fig.3 illustrates the spring 1 of Fig.2, although it could be of the form shown in Fig.l, around which there is a sleeve 6 provided with a cutter 4. The sleeve is welded at 7 to the spring 1.
  • Fig.4 is a modified version of the Fig.3 arrangement where the sleeve 6 is replaced by a curved plate member 8 fitted with a cutter 4 and welded at 9 to the spring 1.
  • Fig.5 is a variation of the arrangement shown in Fig.4.
  • Fig.6 varies from the previous embodiments in that the cutter 4 does not move linearly with the spring during compression/decompression.
  • the cutter 4 has a body 10 of predetermined length and it is welded to the clamping coil 3 of the spring 1.
  • Fig.7 shows a variation of the Fig.6 arrangement in that the cutter body 10 is replaced by a sleeve 11 provided with a cutter 4.
  • the sleeve 11 slides over the spring body and it is provided with a rear end flange 12 which abuts the clamping coil 3.
  • Figs.8 and 9 show a variation of the Fig.7 cutter in that a support bar 13 is provided and the bar 13 has an out turned flange 14 at one end to abut the clamping coil 3. The bar 13 is joggled at 15 to provide the cutter 4.
  • Figs.10,11,12 show the operation of the cutter of the form shown in Figs.8 & 9.
  • a container with a side 16 shown in part and provided with a bag nozzle receiving opening 17.
  • the liner bag in the container is identified 18 and the nozzle 19 is welded to the outside of the liner bag with the bore of the nozzle covering a membrane forming portion 20 of the liner bag 18.
  • the bag nozzle 21 has a internal threaded zone 22 to receive a threaded first end of a cutter support 23.
  • the other end of the cutter support 23 is also threaded and it has a clamping member 24 mounted thereon.
  • the member 24 can be part of a flow control valve, not shown.
  • the spring 1 is housed in the bore 25 of the support 23 and the clamping coil 3 abuts the outer end of the support 3 and is clamped thereagainst by a shoulder 26 in the bore of the member 24.

Abstract

Le dispositif de perçage d'un sac comprend un porte-lame (23) et une lame (4) ainsi qu'un ressort de compression (1), ces derniers étant reliés au porte-lame (23) de sorte que la rotation du porte-lame (23) se traduise par la rotation de la lame (4), tous deux étant situés dans l'espace cylindrique (25) du porte-lame (23) et s'étendant au-delà d'une première extrémité du porte-lame (23). Ce porte-lame (23) est adapté pour être relié par vissage à un ajutage (19) d'une garniture (18) d'un récipient pour, premièrement, mettre en contact une extrémité d'attaque (5) du ressort (1) avec une membrane (20) recouvrant l'alésage de l'ajutage (19) puis, deuxièmement, comprimer le ressort (1) pour pousser la lame (4) contre la membrane (20) afin de percer et couper partiellement un rabat (28) de la membrane (20); ensuite, le ressort (1) libéré se détend à l'intérieur de la garniture (18) pour empêcher le rabat (28) de pénétrer dans l'alésage de l'ajutage (19).
