Definitions

  • a device for emptying a pasty mass containing tubular bag with the in the first part of the claim 1 features is known from DE 1 536 003 A.
  • the tubular bag is supported there by a basket, in a cylinder receiving the tubular bag is used.
  • When emptying the tubular bag enters the basket and is protruding from through the basket Piercing thorns.
  • DE 9 103 038 U discloses a further device according to the first part of claim 1.
  • a knife inserted into the device with a transverse to the radial direction of the tubular bag Surface.
  • To empty the tubular bag is on whose rear end exerted pressure, extending through the bag contents continues and the front hose end against the oblique knife edge presses. This will make one at the front End of hose bag existing, running from the center to the outside Crease cut and opened the tubular bag.
  • the tool is designed as a stationary element, so it is a complete piston feed to complete emptying of the tubular bag in the way.
  • the invention is based on the object, a device for emptying a paste containing a pasty mass Tubular bag to provide a safe opening and restless Draining guaranteed.
  • the device should can also be used with machine-operated dispensing devices his.
  • the embodiment according to claim 4 may during application of pressure on the rear end of the bag a depression located part of the tubular bag film in the Deform dent into it until it is the most overstretched middle area of the foil is the tip of one in the Well arranged mandrel reached and thereby bursting is brought.
  • the bursting of the overstretched film leads - what favorable for an unhindered dispensing of the bag contents is - to a much larger opening than they through mere piercing or achieved by cutting with a knife becomes.
  • the embodiment of the invention according to claim 5 is in With regard to the smallest possible axial length of the entire Device cheap.
  • the arrangement according to claim 8 is expedient in that as she ensures that the most bulging and stretched Part of the tubular bag film in contact with the Dorn dictate is brought.
  • the device shown in FIGS. 1a and 1b consists of a cap arrangement which comprises two cap parts 11 , 11 ' integrally connected via a central part 10 .
  • Each cap part has a transverse wall 12 , 12 ' , a circular-cylindrical flange 13, 13' pointing backwards (in FIG. 1a) and a circular-cylindrical trough 14, which is arranged in each case in the center and protrudes downward (in FIG. 1a) '14' up.
  • the front end of a suitably sized tubular bag 15 , 15' is inserted and connected to the flange 13 , 13 ' .
  • the trough 14 , 14 ' serves to accommodate the front, as closed by a clip tubular bag lobes.

  • the mandrel 18 is located next to the opening of the outlet nipple 17th
  • the recess 16 ' is, as shown in Figure 2, a total of approximately segmental.
  • the application pressure causes the part of the tubular pouch 15, 15 ' located above the respective depression 16, 16' to bulge into the depression until it reaches the mandrel tip 19 , 19 ' and thereby bursts open.
  • the length of the mandrel 18 , 18 ' is dimensioned in relation to the depth of the recess 16 , 16' and taking into account the film material so that the mandrel tip 19 , 19 'is not touched until the film is sufficiently overstretched and when bursting as possible forms large opening. In this way, it is ensured that the tubular bag contents can flow unhindered into the depression 16, 16 ' and from there into the outlet nipple 17, 17' .
  • the recess 16, 16 ' forms with the surface of the transverse wall 12 , 12' a rounded as little as possible and - unless it is to be feared damage to the film - substantially sharp edge to hinder slipping of the tubular bag film.

  • the mandrels 18 , 18 ' may also be so long that their tips 19 , 19 ' are aligned with the plane of the respective transverse wall 12 , 12 ' .
  • the apparatus of Figure 2 differs from that of Figure 1a and 1b in that the tubular bag scoring tip 29, 29 ' at the end of a tapered cylindrical tube 28 , 28' is formed, with its other end coaxially in the respective outlet nipple 27th , 27 ' protrudes and is integrally formed on these over a predetermined breaking point 26 , 26' .
  • the force required for destroying the predetermined breaking point 26 , 26 ' is to be greater than the force required is to burst the tubular bag film by the tip 29 , 29 ' .
  • the design according to FIG. 2 is also possible in the embodiment according to FIGS. 1a and 1b.
  • FIG. 3 The embodiment of Figure 3 is consistent with that of Figure 2 is largely identical, but the tubes 38 , 38 ' in this case to the cap parts 31, 31' are not formed on predetermined breaking points, but resiliently biased against the emptying direction.
  • the bias voltage originates in each case from a spring 36, 36 ', which is supported on a projection 34, 34' provided in the interior of the outlet nipple 37, 37 ' .
  • the force of the spring 36 , 36 ' is to be dimensioned so that when advancing the dispensing piston exerted by the tube tip 39, 39' on the tubular bag film pressure sufficient to score the tube bag and cause it to burst.
  • the tip 49, 49 ' acting on the tubular pouch film is formed at the end of a lever 48, 48' integrally formed on the transverse wall 42, 42 ' and in its unstressed position from the transverse wall 42, 42 'runs diagonally upwards.
  • the tip 49, 49 ' is located in or near the axis of the respective outlet nipple 47, 47'.
  • the two tubular bags 45 , 45 ' are shown without special end closures. They can be designed as in FIG. 1 a or in FIGS. 2 and 3, wherein the transverse walls 42 , 42 'can optionally be provided with trough-like formations similar to FIG. 1 a.
  • the Cap arrangement for jointly receiving two each Shaped tubular bag is the same also applicable to designs in which a cap assembly provided for three or more bags or each of several Bags with a separate cap or only a single bag with cap is present.
