Definitions
- the present invention relates to plastic containers with a homogeneous wall thickness.
- the present invention further relates to the manufacture of these
- containers made of plastic, in particular polycarbonate are known. These containers are made, for example, from compositions (also called compounds) which are a polymer, in particular polycarbonate, and conventional ones
- compositions of the polymer (polycarbonate) and the additives are also referred to as plastic.
- the additives which are also called additives, are, for example, stabilizers, processing aids and others.
- the plastic containers can also include other components, such as rubber seals or
- Containers made of plastic can include, for example, the named and / or other components.
- container made of plastic means containers containing plastic.
- Plastic containers have numerous advantageous properties such as high transparency, good mechanical properties, high resistance to environmental influences and long life, as well as low weight and easy, inexpensive to manufacture.
- the plastic containers can be produced, for example, by the extrusion blow molding process or by the injection stretch blow molding process.
- the extrusion blow molding process is usually carried out with a single-shaft extruder
- the injection stretch blow molding process is a combination of injection molding and blow molding.
- the injection stretch blow molding process is carried out in three stages:
- the injection stretch blow molding process is disclosed, for example, in Anders, S., Kaminski, A., Kappenstein, R., "Polycarbonate” in Becker, / Braun, Kunststoff-Handbuch, Volume 3/1, Polycarbonate, Polyacetale, Polyester, Celluloseester, Carl Hanser Verlag Kunststoff, Vienna 1996, pages 213 to 216.
- the plastic containers known from the prior art have the disadvantage that they do not meet certain requirements which are important for the practical use of the containers.
- the present invention is therefore based on the object of providing containers made of plastic which have high mechanical strengths with the least possible material expenditure.
- the non-uniform wall thickness of the containers which are known from the prior art, results from their manufacture, since the plastic melt gives uneven wall thicknesses during processing by the extrusion blow molding process or by the injection stretch blow molding process.
- the object of the present invention is achieved by a container containing plastic, the regular container wall at its thickest point being at most three times as thick as at its thinnest point.
- the regular container wall at its thickest point is preferably at most 2.6 times as thick as at its thinnest point.
- the regular container wall at its thickest point is particularly preferably at most 2.2 times as thick as at its thinnest point.
- the container is preferably a bottle.
- the container is particularly preferably a water bottle.
- the container preferably contains the plastic polycarbonate.
- the object of the present invention is achieved by a method for producing the container according to the invention by extrusion blow molding or by injection stretch blow molding.
- Rotationally symmetrical containers are preferred. Containers with only one opening are preferred.
- a regular container wall means the container wall at all those places where thicker or thinner places are not intentionally provided. 4 such deliberately thicker places can be seen in the area of the bottle neck.
- the regular container wall would be the same thickness everywhere under ideal production conditions.
- the containers according to the invention were produced, for example, from a polycarbonate with certain theological properties. Therefore, the uniaxial stretch test with which these theological properties can be measured will be described below.
- the uniaxial stretch test of polymer melts and its implementation are known to the person skilled in the art.
- the uniaxial stretch test can be carried out with Münstedt-type devices. These are described in H. Münstedt, J. Rheol., Volume 23, pages 421 to 436 (1979). These are also described in common textbooks such as in Ch. W. Macosko: Rheology, Verlag WileyNCH,
- the determination of the shear viscosity as a function of time is preferably carried out in a rotary rheometer at low shear rates.
- the shear viscosity can also be determined in a rotary rheometer under oscillating deformation and converted to a time-dependent viscosity using common methods.
- the structure and use of rotational rheometers are described in common textbooks. For example, in M. Pahl, W. Gleissle, H.-M. Laun: Practical Rheology of Plastics and Elastomers, NDI Verlag, 1995.
- the expansion viscosity as a function of time is preferably determined using a Münstedt expansion rheometer.
- the uniaxial stretching test can also be carried out with a number of other rheometers, for example with the commercially available stretching rheometer from Meissner. This is described in J.
- the Hencky strain ⁇ is a dimensionless quantity.
- the expansion viscosity r ⁇ _ has the unit Pascal multiplied by seconds.
- the shear viscosity ⁇ also has the
- the quotient S serves as a measure of the relative increase in the expansion viscosity ⁇ e.
- the quotient S is dimensionless.
- S is the quotient of the expansion viscosity T
- the total strain ⁇ (unit: dimensionless) is with the sample length L o (unit: meter) and the current sample length L (unit: meter) as well as the strain rate ⁇ (unit: 1 divided by second) and the time t (unit: second) linked via:
- a plastic in particular polycarbonate, is particularly preferred in which the ratio S at a temperature of 200 ° C. is greater than 1 with a Hencky strain ⁇ of 2.0 and a strain rate range ⁇ between 0.1 and 0.01 3, and that with a Hencky strain ⁇ of 2.5 and a strain rate range ⁇ between 0.1 and 0.01 it is greater than 1.5.
- the present invention relates to a container containing plastic. What is meant here is a container that contains the plastic, for example, as wall material. What is not meant is a container made of completely different materials that only contains the plastic as a filling.
- the present invention furthermore relates to a process for producing this container by extrusion blow molding or by the injection stretch blow molding process.
- plastics in particular polycarbonates
- the person skilled in the art can set various parameters of the plastics, in particular polycarbonates, in a targeted manner. For example, it can influence the molecular weight and the degree of branching.
- the choice of monomers and comonomers or of the end groups also has an influence on the expansion rheological
- the present invention is not limited to containers containing plastics in which the plastics have the theological properties mentioned. These are only preferred because they allow the containers to be manufactured using simple and known processes (extrusion blow molding or injection stretch blow molding). In general, it is only important to achieve the homogeneity of the wall thickness mentioned. This can also be done with other methods and other plastics (eg injection molding or pressing).
- the containers according to the invention have the advantage that they have a high mechanical strength for a given amount of plastic per container.
- the containers according to the invention have numerous other advantages. They are resistant to mechanical loads, i. H. unbreakable and also have an advantageous range of other mechanical properties. They have good optical properties, in particular they have high transparency. They have a high heat resistance.

They are easy and inexpensive to produce by known methods. The good processing properties of the plastic, in particular polycarbonate, are advantageously expressed here. They have a low one
