This case relates to a large-volume bottle (1000 C.C-5000C.C). More specifically, the large-volume bottle is made by a blow molding technique and has a handle integrally formed with the bottle body.

Please refer to the first figure, a conventional large volume bottle, which is a hollow molded product made by blow molding technology. The large-volume bottle 1 can be roughly divided into a threaded bottle mouth from the top to the bottom (in the drawing, the bottle cap 10 is coupled to the threaded bottle mouth), the bottle shoulder 11, the bottle body 12, and the bottle bottom 13. The bottle shoulder 11, the bottle body 12 and the bottle bottom 13 are cross-sectional profiles of rounded rectangles, and the upper half of the bottle body 12 has a volume constriction portion 121 recessed toward the central axis, the volume constriction portion A handle 122 is formed in 121. The four sides of the bottle body 12 are vertical and have no reinforcing or pressure resistant design thereon. The center of the bottom 13 is slightly raised toward the inside of the bottle to increase the structural strength.

The above-mentioned large-volume bottle is used for accommodating liquid materials, and its capacity is usually set between 1000 C.C and 5000 C.C. The liquid content produces a large internal pressure on the large-volume bottle, and the large-volume bottle is subjected to the impact of the top pressure, the side pressure and the indefinite direction due to stacking, collision or accidental falling during storage and transportation. The above-mentioned large-volume bottle structure is lacking in effectiveness. In the case of reinforcement and pressure resistance design, the problem of cracking easily occurs.

The fifth feature is that the length of the first groove extends to the bottom corner edge of the bottle body, and the first groove forms a reinforcing concave corner which is triangularly recessed toward the inner portion of the bottle at the bottom end corner of the bottle body.

The bottom of the bottle has a first groove and a second groove which are disposed along the diagonal and are recessed into the interior of the bottle. The first groove and the second groove converge at the center of the bottom of the bottle, thereby increasing the rigidity of the entire bottom of the bottle. .

The first groove and the second groove have the characteristics of groove depth grading, and the rigidity of the bottom of the bottle is increased by the change of the groove depth, and the groove depth of the first groove is gradually greater than the groove depth of the second groove; Further, the first groove and the second groove have the characteristics of the groove width gradation, and the groove width of the first groove is gradually more than the groove width of the second groove; thereby increasing the rigidity of the entire bottle bottom. .

The first groove forms a reinforcing concave corner which is recessed toward the inside of the bottle at the corner of the bottom of the bottle to increase the rigidity of the corner of the bottom of the bottle.

The lower half of the bottle body has an inwardly concave film attachment portion, and the four sides of the film attachment portion are respectively provided with geometric grooves, and the groove is preferably rounded and rectangular. According to the side pressure and the topping strength of the bottle body, and can resist the hydraulic pressure inside the bottle, the bottle wall is prevented from being outwardly convex.

The body half of the bottle has a three-dimensional configuration feature of upper narrow width and lower width, so that it is easier to maintain the uniformity of the thickness of the bottle wall in the blowing process and increase the top pressure strength of the bottle body.

The side wall of the half of the bottle body has a planar feature of upper narrow and lower width, thereby increasing the lateral compressive strength of the bottle body.

Through the above various structural features, the tolerance strength of the large volume bottle of the present invention to the internal pressure, the top pressure, the lateral pressure and the impact force in all directions is improved.
