Detailed Description
The invention is further described below with reference to the drawings.
As shown in the figure, the plastic barrel for packaging and storing liquid comprises a barrel neck 1, a barrel body 2 and a barrel bottom 3 which are integrally formed, wherein the barrel body 2 is of an elliptic cylinder structure or an elliptic cone structure or the upper part is of an elliptic cone lower part is of an elliptic cylinder structure, the barrel bottom 3 is of an elliptic plane structure, the ratio of the long axis to the short axis of the barrel bottom 3 is greater than or equal to 6:5, the barrel bottom 3 is provided with a central line 7 along the long axis, and the barrel bottom 3 is of a concave structure along the local position of the central line 7.
Further, the barrel bottom 3 is concaved inwards along the center line 7 to form a V-shaped or U-shaped structure.
Further, the front and back surfaces of the barrel body 2 are of symmetrical structures, and the connecting parts of the two sides of the front and back barrel bodies are two symmetrical mould seam lines 4.
Further, the lower parts of the front and rear sides of the barrel body 2 are provided with transverse crease lines 6, and a space is arranged between two ends of the transverse crease lines 6 and the mould seam lines 4.
Further, when the upper part of the barrel body 2 is an elliptical cone and the lower part of the barrel body is an elliptical cylinder structure, transverse reinforcing ribs 5 are arranged on the front and rear surfaces of the joint part of the elliptical cone and the elliptical cylinder.
Further, the center line 7 is straight in the middle, and both ends extend to the two-sided mold seam line 4, and the extending line is inclined upward from the horizontal line by 20 ° to 70 °, preferably 42 ° to 48 °, more preferably 45 °.
Further, a transverse crease line 6 is arranged at a height h from the barrel bottom 3, the height h of the transverse crease line 6 from the barrel bottom is determined by the following formula,
h=｛〔2πb+4（a-b）〕÷2-2a｝÷2+h1
