Abstract

The invention relates to a container produced from a plastic material in extrusion blow molds with a container body, having a first end, and a second end substantially opposite the first end, a first and second sealing surface formed on the inner wall of the first end, wherein the first and second sealing surfaces surround a filling opening and can be connected to one another in a fluid-tight manner, and a container base having a standing surface formed at the second end. A pouring element is formed on the container at the first end below the first and second sealing surfaces.

First claim

The invention claimed is:

1. A container produced from a plastic material, especially in extrusion blow molds, comprising:
a container body having a first end and a second end substantially opposite the first end;
a first sealing surface and a second sealing surface formed on an inner wall of the first end, wherein the first and second sealing surfaces surround a filling opening and are configured to be connected to one another in a fluid-tight manner, wherein the first and second sealing surfaces form a seam with a long side and a first and second seam end when the sealing surfaces are connected in the fluid-tight manner, wherein a first and a second shoulder are formed on the container adjacent to the long side of the seam, and wherein the first shoulder is longer than the second shoulder and the pouring element is formed on the first shoulder;
a container base forming a standing surface at the second end; and
a pouring element formed on the container body at the first end below the first and second sealing surfaces.

2. The container according to claim 1 , wherein the pouring element is blow molded together with the container.

3. The container according to claim 1 , wherein the pouring element is formed below the long side of the seam.

4. The container according to claim 1 , wherein the pouring element is formed below the first or second seam end.

5. The container according to claim 1 , wherein the container base has a shape of an ellipse with a main axis and a secondary axis, whereby the container has two opposing long sides and two opposing short sides.

6. The container according to claim 5 , wherein the seam is oriented parallel to the main axis.

7. The container according to claim 5 , wherein the seam is oriented parallel to the secondary axis.

8. The container according to claim 5 , wherein the pouring element is formed on one of the short sides.

9. The container according to claim 5 , wherein the pouring element is formed on one of the long sides.

10. The container according to claim 1 , wherein the pouring element has a height, so that in a top view of the container the pouring element is within contours of the container base.

11. The container according to claim 1 , wherein the pouring element has a neck, a cap and a pour opening, wherein the cap closes the pour opening.

12. The container according to claim 11 , further comprising a cutting line formed at the neck.

13. The container according to claim 11 , wherein the cap is connected to the container body by a holding strip.

14. The container according to claim 1 , wherein the pouring element is olive-shaped in cross-section.

15. The container according to claim 1 , wherein the pouring element is teardrop-shaped in cross-section.

16. The container according to claim 1 , wherein a teardrop-shaped base is formed at a transition from the pouring element to the container body.

17. The container according to claim 1 , wherein the pouring element has a pyramid shape, wherein one side of the pyramid shape is a cut-off cap.

18. The container according to claim 17 , wherein the cut-off cap has a truncated cone shape.

19. The container according to claim 1 , wherein the pouring element adjoins the long side of the seam or projects into the seam.

20. The container according to claim 2 , wherein the pouring element has a lens-shaped projection.

21. The container according to claim 2 , further comprising a pair of lens-shaped projections, each formed on one of the first and second shoulders, which lens-shaped projections lie opposite one another on the shoulders.

22. The container according to claim 1 , further comprising a vent opening on the container body.

23. The container according to claim 1 , further comprising a closure cap configured to close the pour opening in a fluid-tight manner.

24. The container according to claim 23 , further comprising an interrupted cutting line at the neck and wherein the cutting line in an interrupted region thereof acts as a hinge for the closure cap.

25. The container according to claim 1 , wherein the container body, first and second sealing surface, container base and pouring element are integrally formed.

26. A container produced from a plastic material in extrusion blow molds, comprising:
a container body having a first end and a second end substantially opposite the first end;
a first sealing surface and a second sealing surface formed on an inner wall of the first end, wherein the first and second sealing surfaces surround a filling opening and are configured to be connected to one another in a fluid-tight manner, wherein the first and second sealing surfaces form a seam with a long side and a first and second seam end when the sealing surfaces are connected in the fluid-tight manner, wherein a first and a second shoulder are formed on the container adjacent to the long side of the seam, and wherein the container base has a shape of an ellipse with a main axis and a secondary axis, whereby the container has two opposing long sides and two opposing short sides;
a container base forming a standing surface at the second end; and
a pouring element formed on the container body at the first end below the first and second sealing surfaces.

27. A container produced from a plastic material in extrusion blow molds, comprising:
a container body having a first end and a second end substantially opposite the first end;
a first sealing surface and a second sealing surface formed on an inner wall of the first end, wherein the first and second sealing surfaces surround a filling opening and are configured to be connected to one another in a fluid-tight manner;
a container base forming a standing surface at the second end;
a pouring element formed on the container body at the first end below the first and second sealing surfaces, the pouring element blow molded together with the container;
first and a second shoulders formed on the container; and
a pair of lens-shaped projections, each formed on one of the first and second shoulders, which lens-shaped projections lie opposite one another on the first and second shoulders.
