Definitions

  • the invention relates to a barrel according to the preamble of claim 1.
  • the nozzle part In order to achieve the most complete possible emptying of a barrel or other similar container, it is generally known to arrange the nozzle part with the emptying opening delimited by it near the wall of the container, so that in the usual inclined position of the container during the residual emptying there are no areas in the former located lower than the lower vertex of the generally circular opening.
  • the arrangement of the nozzle part delimiting the emptying opening in the immediate vicinity of the barrel wall has the disadvantage that the nozzle part is less protected against lateral forces acting on the barrel from the outside even when it is arranged in a trough-shaped depression of the upper floor.
  • the neck part protrudes to a certain extent into the interior of the barrel. This ensures that, on the one hand, the section of the connecting piece projecting upwards relative to the region of the top floor which has the emptying opening is noticeably shorter, so that the depth of the trough receiving the connecting piece part can also be chosen to be correspondingly smaller.
  • the socket part must be made long enough to give a sealing plug which is screwed into the socket part provided with a corresponding inner fabric, a sufficiently tight fit.
  • the reduction in the depth of the trough receiving the nozzle part in the top of the barrel leads to a reduction in the size of those areas of the barrel which, in the inclined position during the residual emptying, lie below the lower apex of the emptying opening.
  • that portion of the nozzle part that protrudes into the interior of the barrel is on the inside a shield of the emptying opening, so that a filling material quantity depends on the axial extent of the portion of the nozzle part protruding into the interior of the barrel, no longer into the emptying opening can drain off.
  • a complete or almost complete emptying of a drum designed in this way is therefore not possible, although due to the reduced depth of the emptying opening and the associated one Trough part receiving trough the areas in the barrel, in which filling material can collect below the lower apex of the emptying opening, become smaller.
  • the invention is based on the object of designing a barrel of the type described in the introduction in such a way that the same can be emptied without the significant residual quantities remaining in the barrel.
  • the aim is that in the last phase of the emptying process, filling material located in the region of the trough-shaped depression cannot readily flow into the other regions of the top floor which are lower in the inclined emptying position of the barrel than the bottom of the trough-shaped depression.
  • an embodiment is to be possible in which no regions or regions of the barrel that are insignificant in terms of volume lie in the inclined emptying position thereof below the lower apex of the emptying opening.
  • the invention proposes that the neck part is provided with at least one opening at its portion, which projects into the interior of the barrel, through which the filling material can flow into the neck part.
  • the opening (s) should end on their side facing the top floor with the inner boundary of the trough-shaped depression in the top floor.
  • the opening (s) open towards the front end of the connecting piece part located inside the barrel.
  • This is useful, for example, if the connecting piece is manufactured by injection molding, since it is easier to demold with openings that are open towards the front end, which thus represent recesses on the front side of the connecting part.
  • a nozzle part the breakthrough chungen are limited on all sides by wall areas of the nozzle part, so that the latter is delimited at its front end by a circumferential wall, be more suitable to absorb the forces that occur when a screw plug is screwed in tightly, without the risk of the nozzle part spreading apart on its inner, front side End exists, which could affect the secure fit of the screw plug in the nozzle part.
  • the top of the barrel in the region of the trough-shaped depression can be provided with a threshold-like projection protruding into the barrel interior, the course of which is adapted to the contour of the depression, and expediently such that the threshold-shaped projection extends along the outer boundary of the barrel Deepening runs.
  • the projection can be formed by a fold in the bottom of the trough-shaped depression, so that an outer groove-shaped depression corresponds to the inner threshold-shaped projection.
  • the inner threshold-shaped projection projects upward from the other regions of the top floor.
  • the threshold-shaped projection prevents the filling material collecting on the inside of the bottom region of the trough-shaped recess from improper movement of the drum entirely or partially runs back into the remaining area of the top floor, which is lower in the emptying position than the area in the immediate vicinity of the emptying opening.
  • the protrusion can be the nozzle part on all sides with the exception of that Surround the outer edge of the barrel facing the trough-shaped depression.
  • the threshold-shaped projection at its end regions facing the barrel edge run out in front of the barrel edge in the bottom of the trough-shaped depression or in adjoining wall and / or floor areas, so that filling material standing in this area also from outside the bottom area of the Trough can flow unhindered in the direction of the discharge opening.
  • the specific design will depend on the respective circumstances.
  • the trough-shaped depression in such a way that the two lateral boundaries thereof have an increasing distance from one another in the direction of the edge of the barrel, the extent of the expansion of the trough-shaped depression in the direction of the barrel edge being chosen such that in the emptying position of the barrel which is inclined more than ninety degrees above the upright position, no place in the interior of the barrel is lower than the lowest point of the associated emptying opening which is connected to the interior of the barrel.
  • the presence of a threshold-shaped projection in the area of the barrel wall would possibly hinder an unimpeded flow of the filling material in the direction of the emptying opening. This would also be the case if the emptying opening is located directly or close to the barrel edge in order to achieve the most complete emptying possible.
  • the arrangement can be such that the upper placement surface of the neck part located outside the barrel and / or the upper boundary surface of a sealing plug screwed into the neck part or a screw cap to be screwed onto the neck part lies or lie in the plane of the top floor of the barrel to also serve as a stand.
  • the barrel 10 consists of barrel body 12, top floor 14 and the bottom floor, not shown.
  • the upper floor 14 is provided with two trough-shaped depressions 18 and 20, in each of which a nozzle 22 or 24 is arranged.
  • Each nozzle defines an opening 26 and 28, respectively.
  • the opening 28 is used for residual emptying.
  • the barrel is pivoted into the positions shown in FIGS. 5-7.
  • Normal emptying is usually effected through the opening 26, for example using a pipe connected to a pump, which is introduced through the opening 26 into the interior of the barrel to near the bottom thereof.
  • the opening 28 can be used for ventilation.
  • Both nozzles 22 and 24 are arranged and dimensioned with respect to their axial extent so that they do not protrude above the upper end face 30, so that the latter can be used as a stacking surface.
  • both connecting pieces 22 and 24 end somewhat below the upper end face 30 of the top floor 14.
  • the barrel 10 is provided in the area of the upper floor 14 and the lower floor with a circumferential ring 31, which is approximately L-shaped in cross section and delimits a groove 33 which is open towards the associated barrel end with the respective floor.
  • Both trough-shaped recesses 18 and 20 are each delimited by an inclined wall region 34 and 36, respectively, which connects the upper region of upper floor 14, which has end face 30, and the floor region 38 and 40, which delimits the respective trough-shaped recess 18 and 20 manufactures.
  • the arrangement is such that the inclined wall regions 34 and 36 are arranged at a distance from the associated connection piece 22 or 24.
  • the base region 40 of the trough-shaped recess 20 merges with the inclined wall region 36 with the interposition of a threshold-like projection 42 projecting into the interior of the barrel.
  • This threshold-like projection 42 is formed by a fold-like depression in the base region 40. It runs along the lower end of the inclined wall region 36, so that during the emptying process, during which the barrel 10 assumes a position inclined by more than 90 ° to approximately 180 ° with respect to the upright position according to FIG.
  • the threshold-like projection 42 thus forms the lateral boundary of a collecting space, in whose approximately central region the emptying opening 28 is located.
  • the two lateral boundaries 48, 50 of the trough-shaped recess 20 have an increasing distance from one another in the direction of the edge, that is to say the ring 31, of the drum, this distance in the region of the drum edge so is chosen that in the emptying position of the barrel, as shown approximately in Figure 5 of the drawing, the areas 52 and 54 adjacent to the trough-shaped depression on both sides in the circumferential direction of the barrel, which are essentially delimited by the barrel wall 56 and each one of the end sections of the inclined wall region 36 adjoining the barrel wall is not lower than the lower apex of the emptying opening 28.
  • the threshold-like projection 42 at both ends at a short distance from the barrel wall as shown in FIG 56 in the bottom 40 of the trough-shaped depression 28 or optionally also in the oblique wa let end area 36 run out so as to achieve a free passage for the filling material collecting in areas 52 and 54 near the barrel wall.
  • the nozzle 24 is first made separately from the actual barrel and then connected to it by welding or otherwise in a suitable manner.
  • the neck 24 projects with its lower part into the interior of the barrel.
  • This configuration allows the area of the nozzle that protrudes upward above the bottom 40 of the trough-shaped recess 20 to be made shorter. This can also reduce the vertical extent of the trough-shaped recess 20. This will generally improve the conditions for the most complete emptying of the keg in that the extent to which the lateral boundaries 48, 50 of the recess 20 must diverge to prevent the formation of areas in the keg when emptied , can be smaller. As a result, the extent of the depression 20 in a plane perpendicular to the longitudinal axis of the barrel becomes smaller, which leads to an enlargement of the end face 30 serving as a stacking area.
  • the nozzle 24 is provided with openings 60 which allow the filling material to flow freely into the nozzle during the emptying process.
  • the openings 60 are arranged so that they end on their side facing the associated barrel end with the inner boundary of the bottom 40.
  • the openings 60 are designed as holes in the wall of the nozzle 24, which are delimited by the nozzle wall over their entire respective circumference.
  • the embodiment according to FIG. 4 coincides in all essential parts with the embodiment shown in FIGS. 1-3 and 5-8, so that the same parts are provided with the same reference numerals, which are 100 times higher.
  • the nozzle 124 is integral with the Upper bottom 114 of the barrel made by injection molding.
  • the openings 160 in the section of the connecting piece 124 projecting into the interior of the barrel are designed as recesses which are open towards the inner front end thereof.
  • the invention is applicable regardless of how the barrel is made. It is thus possible to produce the barrel by extrusion blow molding, the emptying opening (s) being able to lie in the closing plane of the blow mold and thus in the weld seam, or through which the preform has been blown out of the barrel by means of welding was closed. But it is also possible to at least one of the openings outside the weld, this opposite z. B. offset by 90 degrees.
  • the bottoms of the barrel are produced by injection molding and are connected by welding to the actual barrel body, which can either be produced by extrusion or by blow molding.
