Definitions
- the present invention relates to a method and an apparatus for producing hollow plastic bodies and to a hollow plastic body produced thereafter.
- State of the art State of the art :
- the plastic containers When testing the stacking capacity, the plastic containers are subjected to increasing pressure until the hollow body is deformed.
- the pressure load on the hollow body creates a compressive stress in the vertical side walls.
- This compressive stress initially leads to a certain increase in circumference and, if the compressive stresses are too high in the regions which cannot deform outwardly, lead to denting inward.
- the stack load leads to bulging (elephant foot) or rolling of the transition radius between the vertical wall and the horizontal floor in the wall areas near the floor.
- these longitudinal ribs are produced exclusively by a corresponding configuration of the blow mold with axially extending indentations during the blow molding from a tubular preform with a constant wall thickness. The thickness of the container wall remains unchanged in the circumferential direction.
- the method according to the invention for the production of blow-molded plastic hollow bodies on a blow molding machine with an extruder, extrusion head with a circumferential distributor and a corresponding blow mold, a targeted adjustment of the wall thickness of the ejected preform being carried out by ejecting the tubular preform from the extrusion head by adjusting the nozzle / mandrel gap is characterized in particular by the fact that a desired thick-thin setting can be achieved over the scope and length of the tubular preform by a sequential or simultaneous action of three differently profiled, separately adjustable nozzle / mandrel gap setting elements.
- This multiple setting option of the hose is of great importance for large-volume hollow bodies such as industrial containers (e.g. 220 liter drums) and is unique in the past and the quality of the containers is unmatched.
- the containers produced in this way with vertical wall areas, a substantially horizontally extending upper floor, or a tightenable lid, with at least one filling and emptying opening arranged therein and a corresponding lower floor have a plurality of spaced apart ribs in the vertical wall areas exclusively on the inside of the Wall on, the wall profile remains evenly smooth and unchanged on the outside.
- the stacking load capacity is noticeably improved, whereby the handling (e.g. the application of drum grippers or a lateral rolling of the drum) is not impaired by the smooth, unchanged drum wall.
- adjacent wall areas alternately have a different thickness of the wall thickness, the transitions from thinner to thicker wall and vice versa on the inside of the wall being wave-shaped with increasing and decreasing curves.
- the wall thickness of the thicker strip-shaped wall areas is of equal thickness and the wall thickness of the thinner strip-shaped wall areas is of equal thickness.
- the plastic container according to the invention is produced in the blow molding process, a tubular preform pressed out of an annular extrusion nozzle being inflated in a blow mold, the preform being adjusted to an evenly increasing wall thickness in the axial direction by means of appropriate nozzle control and by means of appropriate nozzle control in the tube areas with the highest Degrees of extension for the 90 ° to the Partition-level container areas of the top and bottom are set to a greater wall thickness, and with the appropriate nozzle control in the tubular preform on the inside and / or on the outside pronounced longitudinal ribs or thick spots are set such that the in a blow mold with a smooth surface for the lateral or vertical Wall areas of completely blown containers, at least in the vertical container wall in the axial direction, have adjacent strip-shaped wall areas with alternately thinner and thicker wall thickness (ribbed drum).
- the new triple or multiple nozzle / mandrel gap setting elements according to the invention advantageously result in a large number of new application possibilities for large-volume plastic blow molded parts of all kinds (for example automotive accessories or the like).
- technical blow molded parts such as, for. B. Plastic fuel tanks (KKB ' s) for the automotive industry in excellent quality.
- Hollow body such as a standard ceiling drum or Vanguard FRH drum
- the axial ribs in the vertical wall areas increase the stiffness of the hollow body, i.e. an increase in the dent resistance of the barrel casing, and the ribs in the axial radii in the transition area to the top of the barrel bottom result in an increase in the rolling resistance of the floor radii.
- the wall thickness of the container has been increased overall and thus the material weight has been increased in order to avoid dents and bulges or a rolling of bottom-side hollow body regions.
- the rib-like thickenings are located exclusively on the inside of the hollow body wall, the ribs can be arranged as follows: in the axial direction only over a certain partial area or over the entire length or height of the cylindrical wall, in the radii or transition areas from the vertical to the horizontal base or cover areas, in the disc-shaped base or cover areas.

- FIG. 1 shows a section of an extrusion head 10 with three adjustable nozzle / dome gap setting elements DO, DS I in connection with DF and DS II in the operating position “nozzle gap open” with extrusion of a tubular preform 22.
- the extrusion head is enclosed by a housing 16.
- the housing 16 there is a hollow cylindrical storage space 18 in which the molten plastic material conveyed from one or more extruders into the extrusion head has been distributed and possibly stored.
- the axially adjustable adjusting elements DS 1 and DS II are also easily detachable and thus easily exchangeable attached to the extrusion head housing.
- the axial adjustability or exact position setting of the adjustable nozzle / mandrel gap setting elements can, for. B. hydraulic or electric motor z. B. using small servo motors.
- the housing-fixed nozzle ring piece DF is easily detachable or exchangeably attached to the extrusion head housing. This serves in particular to be able to quickly replace the ring pieces and adjusting elements of the nozzle gap, which are tailored to the respective product and correspondingly profiled, when the product is changed or the downstream blow mold halves are exchanged.
- the respective path lengths for the adjustability of the setting elements are indicated by corresponding arrows.
- the surfaces of the fixed nozzle ring piece DF and the setting element DS II delimiting the nozzle gap are profiled and the surfaces of the dome D 0 and the setting element DS I delimiting the nozzle gap are smooth all round.
- the nozzle gap 20 is delimited on the outside by the lower, inner, smooth peripheral edge of the nozzle slide DS I and on the inside by the axially adjustable mandrel 14.
- the emerging hose 22 is formed uniformly thin over the circumference.
- the profiles of the fixed nozzle ring piece DF and the setting element DS II are not in the active engagement position.
- the nozzle slide DS I is simply raised with its smooth lower edge.
- the nozzle slide DS II can be lowered a bit.
- the circumferential tooth profile with teeth 24 and tooth gaps 26 evenly spaced apart from one another is indicated in the illustration on the right.
- the setting element DS I together with the setting element DS II is moved upward a little (see arrow), so that these two setting elements are not in an active engagement position with the exiting tubular preform 22.
- the nozzle gap 20 is then limited by the mandrel 14 and the profiled fixed ring piece DF.
- the hose 22 emerging from the nozzle gap is then no longer uniformly thick in the circumferential direction, but rather is formed somewhat thinner in two opposing regions (mold division plane of the blow mold) than in the hose regions arranged offset by 90 °.
- Such a double-oval setting of the nozzle gap or oval wall thickness setting in opposite areas of the hose is generally customary for blow parts with a flat top and bottom.
- the two opposing tube regions with thicker walls are guided between the opened blow mold halves in such a way that the horizontal container wall regions with the greatest degrees of stretching, which are at 90 ° to the mold-dividing plane or inflation paths of the plastic material are blown.
- This measure thus serves to even out the wall thickness in the finished container, so that the container wall in corner areas with high degrees of stretching or stretching is not thinner than in the other wall parts.
- the present invention includes the technical teaching of taking a third additional measure for the first time while maintaining the two previous measures to achieve a uniform wall thickness in the finished blown hollow body in order to be able to produce deliberate and reproducible irregularities in the wall thickness of the finished blown hollow body in a container production .
- Different design variants of the extrusion head according to the invention are described in more detail in the parallel PCT application PCT / EP99 / 01398 by the same applicant.
- a wall thickness control program for a targeted wall thickness adjustment over the length of the extruded tube is shown schematically in FIG.

- nozzle slide D 0 axially adjustable mandrel 14
- a continuous increase in the wall thickness over the length of the preform 22 is set according to program a) by slowly and steadily opening the nozzle cross section.
- the second adjusting device - the nozzle slide DS I in connection with the profiled nozzle ring DF - is used in the two longitudinal areas of the extruded preform (in the vicinity of the later squeezing edges across the hose) by appropriately enlarging the nozzle cross-section with outflow of additional plastic material (no displacement) a partially larger wall thickness is set over its circumference, and with the third setting device - the adjustable nozzle slide DS II with tooth / tooth space profiling - according to program c) a thick / thin setting of the wall thickness with formation of longitudinal ribs by partial lateral displacement of the art made of material in the nozzle gap.
- a simplified tubular preform 22 is shown in FIG. 3 in longitudinal section at the top and in triple cross section below for a special blown hollow body, namely a plastic fuel tank (KKB) 34.
- the tubular preform 22 is thicker at the top according to section A-A than at the bottom according to section C-C.
- the partial thick spots according to part program b) by means of the nozzle slide DS I are omitted for the sake of simplicity.
- the section B-B illustrates a single additional thick point 32, which is provided for the formation of a lateral opening in the finished container.

From the top view of this canister in FIG. 9 it can be seen in the partial cut areas that the axial ribs 44 run a little bit horizontally into the lower bottom area of the canister, while the corner areas of the canister are free of any rib formation. The axial ribs 44 stiffen the straight wall parts against excessive bulging when internal pressure occurs inside the canister. In contrast, in another canister 52 shown in FIG. 10, corresponding inner ribs 54 are formed only in the corner regions. These corner ribs 54 can be seen in the top view in FIG. 11 in the partially cut corner areas; they increase the stacking capacity and reduce the bulging (elephant feet) of the corner areas of such a canister.
- reference numeral 56 denotes a lid barrel in the worldwide known version of the standard lid barrel developed by Mauser in 1975.
- a multiplicity of strip-like, spaced apart ribs 58 are indicated, which extend into the bulbous barrel body areas.

- the cross-sectional illustration in FIG. 15 again shows the barrel body wall with inner ribs 68 in the left half of the figure and the wall area without ribs in the right half of the picture, very close above the barrel bottom.
- a transverse line can be seen in the barrel bottom, which represents the pinch seam 70 of the tubular preform in the mold division plane of the blow mold.
- a closed bung 72 is shown in FIG.
- the inner ribs 74 shown in FIG. 17 increase the stacking capacity of the barrel body, particularly in the case of hot filled liquid contents.
- the plastic inner container 76 for a pallet container is shown in FIG.
- the inner ribs 78 indicated here which are formed in the flat wall areas, stiffen these wall areas and prevent the wall from bulging inward when the containers are empty.
- the barrel diameter of a 55 gallon Vanguard lid barrel is approx. 590 mm.
- the distance (thin point) between two adjacent ribs should be at least about twice or a multiple of the width of a rib.
- the preferred number of ribs is approx. 32.
- a smaller number and for containers with larger diameters a larger number of inner stiffening ribs should be selected.
- an increase in the stacking capacity of the containers according to the invention - in particular when used for hot-filled liquid contents - can be achieved in the order of magnitude of 5% to 20% compared to conventional containers.
- the strip-like ribs in the vertical barrel wall preferably run only to just below the handling ring and not to the L- Ring or the top floor.
