DETAILED DESCRIPTION OF THE INVENTION

[0059] FIG. 1 shows a view of a plastics material container 1 according to the invention. This container has a bottom section 2. This bottom section 2 is adjoined by a main body 4 of the container, which forms a substantial part of the volume for holding a liquid. A labeling region 42 is provided within this main body. The reference sign hG indicates the height of this main body in the longitudinal direction of the container. The reference sign hB indicates the height of the bottom section (also in relation to the longitudinal direction).

[0060] Adjacent to the main body in the longitudinal direction L of the container is the lower shoulder, then the above-mentioned deformation section 6, which has a height hD. This deformation section 6 is followed by the shoulder region 8 of the container, and this in turn by a mouth region 10 with a height hM.

[0061] It can be seen that the main body section extends over more than half the height of the entire container. The height hD of the deformation section is preferably less than the height hS of the shoulder region and also less than the height hG of the main body.

[0062] The reference sign 12 refers to a conical region, which is preferably arranged between the deformation section and the main body 4 and which particularly preferably tapers towards the top.

[0063] FIG. 2a shows a detail of the container shown in FIG. 1.

[0064] It can be seen that two grooves 62 and 64, arranged one above the other in the longitudinal direction L, are provided in the deformation section 6. The groove 62 has three groove sections 62a, 62b, and 62c that adjoin one another and are located one after the other in the circumferential direction. A groove base of these three groove sections is the same size in each case. The cross-section of a groove section, such as groove section 62b, preferably widens from its starting point A to a central region M and then tapers again to its end section B. Preferably, the groove sections are each symmetrical with respect to a plane which extends in the longitudinal direction of the container through the center of the groove sections and which extends in a radial direction of the plastics material container.

[0065] It can be seen that the groove sections 64a and 64b are offset here by half a pitch in the circumferential direction of the container relative to the groove sections 62a, 62b, and 62c.

[0066] In addition, another groove 82 is provided (above the grooves 62, 64), which is formed in the shoulder region 8. It can be seen that this further groove is formed circumferentially without interruption.

[0067] FIG. 2b shows a further detailed view of a slightly modified container, which, however, can preferably be combined with the above embodiments.

[0068] It can be seen that three grooves 62, 64 and 66 arranged one above the other in the longitudinal direction L are provided in the deformation section 6. The groove 62 has three groove sections 62a, 62b, and 62c that adjoin one another and are located one after the other in the circumferential direction. A groove base of these three groove sections is the same size in each case. The cross-section of a groove section, such as groove section 62b, preferably widens from its starting point A to a central region M and then tapers again to its end section B. Preferably, the groove sections are each symmetrical with respect to a plane which extends in the longitudinal direction of the container through the center of the groove sections and which extends in a radial direction of the plastics material container.

[0069] It can be seen that the groove sections 64a and 64b are offset here by half a pitch in the circumferential direction of the container relative to the groove sections 62a, 62b, and 62c.

[0070] The groove 66 also has three groove sections 66a, 66b and 66c here. In the rotational position, these are again arranged at the same position as the groove sections 62a, 62b and 62c of the groove 62.

[0071] In addition, a further groove 82 is provided (above the grooves 62, 64, 66), which is formed in the shoulder region 8. It can be seen that this further groove is formed circumferentially without interruption.

[0072] FIG. 3 shows a representation of the container shown in FIG. 2, with individual sections A, B, C and E highlighted to illustrate them in more detail below. It can be seen that a plurality of grooves are also formed here above the labeling region 42 and below it.

[0073] FIG. 4 shows a detailed view in the region of the main body, or of the grooves arranged there. It can be seen here that these grooves are connected to one another by a very short groove base. The grooves have a radius of curvature which is between 1 mm and 2 mm, preferably between 1.2 mm and 1.8 mm, and particularly preferably between 1.3 mm and 1.7 mm.

[0074] FIG. 5 is a detailed view in a region of the uppermost groove 66 in the deformation section. It can be seen that, viewed from above, the wall has a radius of curvature R1 and, below this, passes into an approximately rectilinear section via an inwardly curved curvature radius R2.

[0075] FIG. 6 shows a plan view of the container shown in FIG. 1. It can be seen that this container is substantially rotationally symmetrical with respect to its longitudinal direction L. In addition, the grooves 62, 64 and 66 in the deformation section can also be seen here from above.

[0076] FIG. 7 shows a view from below of the bottom section of the container. Here, one can see a total of eight long ribs 32 running in the radial direction, which end in the central region 34 of the bottom section. The reference sign 36 indicates a center of the bottom section which preferably has the injection point.

[0077] The reference signs 38 indicate furtherbut shortenedradial ribs, each of which is arranged between the first reinforcing ribs 32. These second radial ribs 38 also extend in the radial direction R but do not extend to the central region, but ending at approximately halfway along the bottom section.

[0078] FIG. 8 shows a view along the arrows EE of FIG. 3, i.e., in the region of the first rib 62 of the deformation section. It can be seen that a total of four rib sections 62A, 62B, 62C and 62D are provided here. At the respective connection points between the rib sections 62, the cross section is at a maximum.

[0079] FIG. 9 shows a sectional view of the container according to the invention. Numerous diameters D1-D14 are shown here. The diameter D3, which at the same time is also the diameter of the footprint of the container, can be seen here, for example. In the area of the labeling section, a maximum cross-section D4 and a minimum cross-section D5 are shown. However, these preferably differ by less than 10%, preferably by less than 5%.

[0080] In the upper section of the main body, two diameters D6 and D7 are also shown, but they are also only slightly different.

[0081] The diameters D8-D12 indicate the individual ribs 62, 64 in the deformation section 6. It can be seen that rib 64 has a smaller diameter overall than rib 62.

[0082] It can also be seen that the bottom section extends slightly inwards, which is indicated by the distance A1. The reference sign hE indicates the height of the label section 42.

[0083] The applicant reserves the right to claim all features disclosed in the application documents as essential to the invention, provided that they are novel over the prior art individually or in combination. It is also pointed out that features which can be advantageous in themselves are also described in the individual figures. The person skilled in the art will immediately recognize that a particular feature described in a figure can be advantageous even without the adoption of further features from this figure. Furthermore, the person skilled in the art will recognize that advantages can also result from a combination of several features shown in individual or in different figures.
