Definitions

  • the invention relates to a barrel according to the preamble of claim 1.
  • the nozzle part In order to achieve a residue-free 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 there are no areas in the usual inclined position when emptying the container located lower than the lower vertex of the generally circular opening.
  • the arrangement of the nozzle part delimiting the drain opening in the immediate vicinity of the barrel wall has the disadvantage that the nozzle part is less protected against forces acting laterally on the barrel from the outside even when it is arranged in a trough-shaped recess in the upper floor. This applies to forces that act directly on the nozzle part.
  • an arrangement of the emptying opening and the connecting piece part delimiting it is often chosen at a noticeable distance from the barrel wall, with a deformation zone, for example in the form of an upwardly projecting bead, being arranged between the connecting piece part and the barrel wall in order to at the barrel edge in At about the level of the discharge opening occurring impact and impact stresses to cause a targeted deformation, which consumes a large part of the impact and impact energy and thus protects the adjacent areas, in particular the nozzle part, from impermissible stresses.
  • a deformation zone for example in the form of an upwardly projecting bead
  • the invention has for its object to design a barrel of the type described in the introduction so that the aforementioned difficulties are at least largely reduced. It should be possible to arrange the emptying opening with the associated nozzle part in such a way that complete or almost complete emptying is possible without on the other hand having to accept any restrictions or disadvantages with regard to the resistance of the barrel in the area of the discharge opening against stresses caused by external forces, in particular impacts and impacts.
  • the invention proposes that the deformation zone which is approximately wrinkled in cross section is arranged in the region between the connecting piece part and the boundary of the trough-shaped depression to the upper end face of the upper floor.
  • deformation zone in the barrel according to the invention which, as in the known arrangement, absorbs shocks and impacts and makes it largely ineffective due to elastic deformation.
  • this deformation zone according to the invention outside the area between the nozzle part and the barrel edge or barrel wall, however, it is possible to arrange the nozzle part with the drain opening in this area, i.e. closer to the barrel wall, if necessary directly so that the outer apex of the drain opening aligned with the barrel wall.
  • the deformation zone When subjected to external forces, in particular blows and impacts on the barrel edge and / or the nozzle, the deformation zone gives way, so that there is no fear of overstressing the barrel, which can lead to cracks or breaks.
  • the deformation zone can be formed as at least one fold protruding into the interior of the barrel in the trough-shaped depression. But it can also as at least one outwardly projecting towards the upper end face of the top floor fold in the trough-shaped Ver be deepened. Of course, in both cases there is the possibility of providing several fold sections and / or several parallel folds. Last but not least, this depends on the space available.
  • the deformation zone can terminate at its two ends with the wall or the edge of the barrel, so that the area and the support part bearing area is delimited by the deformation zone compared to the remaining area of the top floor. If, as is often the case, the barrel is provided with an integral L-shaped ring at its end regions, according to a further proposal of the invention, the deformation zone at both ends can enter the circumferential groove delimited by the ring located at the associated barrel end leak. This is particularly advantageous if the deformation zone is or are designed as a fold (s) protruding into the inside of the barrel, which also form or form an upwardly open groove.
  • the two lateral boundaries of the trough-shaped depression can have an increasing distance from one another in the direction of the edge of the barrel.
  • an embodiment is advantageously selected in which the deformation zone ends at an acute angle, preferably approximately tangentially, in the barrel wall or in the groove delimited by the L-shaped ring.
  • Such a configuration may not be very advantageous since the fold protruding outwards in the direction of the upper end face of the top floor in the emptying position of the barrel creates a deeper, groove-like channel in which contents are collected. In this case, this channel should merge into the adjacent wall areas at both ends in such a way that the filling material collecting therein can run out.
  • the nozzle part can protrude at least with a portion of its axial extent into the interior of the barrel, so as to shorten the portion of the nozzle part that protrudes outwards from the trough bottom. This measure helps to reduce the risk of external forces acting directly on the nozzle part.
  • the neck part is provided with at least one opening at its section, which protrudes into the interior of the barrel, through which the filling material enters the neck part can flow in.
  • the opening (s) should end on the side facing the top of the barrel with the inner boundary of the trough-shaped depression in the top.
  • 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 through which the preform from which the barrel has been blown can be welded was closed. However, it is also possible to arrange at least one of the openings outside of the weld seam offset from it, for example by 90 °.
  • the nozzle parts assigned to the openings can be molded in one piece in one operation. But they can also be manufactured as separate nozzle parts and connected to the barrel by means of welding.
  • Another possibility is to manufacture the bottoms of the barrel by injection molding and to connect them to the actual barrel body by welding, which can be produced by extrusion or blow molding.
  • the problems described in the introduction with regard to emptying the barrel as completely as possible on the one hand and arranging a deformation zone for accommodating in particular shock and impact stresses are the same in all cases, regardless of the type of manufacture, so that the invention can therefore be used with advantage in all cases.
  • the barrel 10 consists of barrel body 12, top floor 14 and the bottom floor, not shown.
  • the top floor 14 is with two trough-shaped depressions 18 and 20 are provided, in each of which a nozzle 22 or 24 is arranged.
  • Each nozzle defines an opening 26 and 28, respectively.
  • the opening 28 of the two openings 26 and 28 located on the top floor serves for the residual emptying.
  • the barrel is pivoted into the positions shown in FIGS. 5 and 6.
  • Normal emptying is usually effected through the opening 26, which may be larger, for example using a pipe connected to a pump, which is introduced through the opening 26 into the interior of the barrel up to the vicinity of 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 respective associated barrel end with the respective associated floor.
  • the trough-shaped recess 20 assigned to the connecting piece 24 is delimited by an inclined wall region 34 which connects the upper region of the floor 14 with the end face 30 and the bottom region 36 delimiting the trough-shaped recess 20 manufactures.
  • the arrangement is such that the inclined wall region 34 is arranged at a distance from the nozzle 24 in its central section.
  • the inclined wall region 34 merges into the base region 36 of the depression 20 with the interposition of a deformation zone 38.
  • This deformation area 38 is formed by a fold 40 which is formed in the bottom 36 in such a way that it projects inwards into the barrel 10.
  • This fold 40 forming the deformation zone 38 runs along the lower end of the inclined wall region 34, so that it forms a transition between this wall region and the bottom 36 of the bottom-shaped recess 20. Consequently, the deformation zone 38 also runs approximately coaxially in its central section at a distance from the connector 24.
  • the deepest 42 of the fold 40 which in the examples shown in the drawing delimits or forms an upwardly open groove, lies approximately at the level of the plane perpendicular to the longitudinal axis of the barrel, in which also the deepest 44 of the groove 33 delimited by the ring 31 lies.
  • Fig. 1 shows that the inclined wall region 34 and thus also the deformation zone 38 begin at a distance in the circumferential direction of the barrel from the nozzle 24 on the barrel wall or the barrel edge and on the other side of the nozzle 24 at the same distance on the barrel wall or The end of the barrel ends, so that the recess 20 is arranged symmetrically to the nozzle 24.
  • the arrangement is such that the two end regions 43 of the deformation zone 38 each extend - in relation to the depression 20 - in an arcuate manner in order to achieve a flowing, approximately tangential transition into the barrel wall at both ends. In the specific case, it goes through the fold 40 delimited groove at both ends into the groove 33, which is delimited by the ring 31 formed on the barrel body and the opposite region of the barrel wall.
  • the deformation zone 38 can also be arranged at a distance from the lower end of the inclined wall region 34, that is to say closer to the connecting piece 24. It is also possible to provide more than one fold, in which case all folds in the deformation region expediently run parallel to one another.
  • the embodiment shown in the drawing should represent an optimum insofar as it requires the least space for the deformation zone 38 and the extension of the trough-shaped depression 20 in the plane perpendicular to the longitudinal axis of the barrel can thus remain as small as possible. This is important because the aim is to obtain the largest possible end surface 30 as a stacking surface.
  • the course of the deformation zone 38 ensures that the nozzle 24 is surrounded by the deformation zone over a larger part of its circumference, so that the effectiveness of the forces acting on the nozzle 24 or the barrel edge is independent of the direction Deformation zone is guaranteed.
  • the base 36 of the depression 20 and thus also the connection piece 24 will experience a temporary slight displacement due to external impact or impact effects. However, this is of no importance, since the base 36 and nozzle 24 can spring back into their original position after the impact or impact stress has ended.
  • the nozzle 24 is provided on its side facing away from the barrel edge with a web-shaped extension 46, which is also connected to the bottom region 36 and is intended to prevent the nozzle from being exerted by forces acting directly on the nozzle 24 is bent too strongly inwards relative to the base region 36 which supports it. This does not rule out the fact that the acting forces lead to a deformation of the fold 40 and are thereby rendered largely harmless.
  • the fold 40 protruding into the interior of the barrel which in the exemplary embodiments shown in the drawing limits the trough-shaped depression 20 on its circumference, insofar as it is defined by the inclined transition surface 34, forms a threshold-shaped projection on the inside of the top floor, which in the emptying position 6 protrudes upwards relative to the other areas of the top floor 14.
  • the threshold formed by the fold 40 prevents the contents which are collecting on the inside of the bottom region 36 from improper movement of the barrel entirely or partially runs back into the remaining area of the top floor, which in the emptying position is lower than the area in the immediate vicinity of the emptying opening 28.
  • Fig. 5 of the drawing shows an intermediate position during the emptying process. It shows that due to the arrangement of the deformation zone 38 possible attachment of the nozzle 24 delimiting the emptying opening directly on the barrel edge during the entire emptying process, ie at all inclined positions of the Barrel, which are necessary, there are no pockets or other areas in the barrel in which fill material collects that cannot drain through the opening for emptying. Apart from the arrangement of the nozzle near the barrel wall, the prerequisite for this is that the two lateral boundary areas of the trough have a sufficiently increasing distance from one another in the direction of the rim of the barrel. This also has the advantage that the deformation zone is given a course which, under the action of force, causes folding in all areas thereof without excessive shear stress. The measure of forming the deformation zone in its longitudinal course without sharp transitions and changes in direction also serves the same target stress.
  • the nozzle 24 shown in Fig. 3 of the drawing is made in one piece with the top panel.
  • the connecting piece 124 is first produced separately from the actual barrel and then connected to it by welding or otherwise in a suitable manner .
  • the lower part of the neck 124 projects into the interior of the barrel. This configuration makes it possible either to make the socket longer in order to obtain a longer thread for the screw closure, or to keep the area of the socket protruding upward above the bottom 136 of the trough-shaped recess 120 shorter.
  • the depth of the trough-shaped depression 20 can also be less.
  • the nozzle 124 is provided with openings 150 which allow the liquid to flow freely into the nozzle.
  • the openings are arranged so that they end on their side facing the associated barrel end with the inner boundary of the bottom 136 of the trough-shaped recess 120.
  • the other, possibly larger, opening 26 with the associated connection piece 22 is arranged at a greater distance from the barrel edge than the opening 28 with the associated connection piece 24.
  • the deformation zone 60 assigned to the opening 26 in the usual way between the nozzle 22 and the barrel edge, approximately parallel to the latter, arranged and designed as an outwardly projecting bead which forms a recess in the emptying position of the barrel, from which the contents collecting therein can hardly be removed. This is avoided in the embodiment according to the invention at the other emptying opening 28 and the associated nozzle 24.
