Lower section is equipped with circular arc platform, and the side wall of the circular arc platform is connected on bottom of bottle bottom surface, and at least three reinforcements are evenly equipped in the bottom of bottle
Rib.
In the present invention, the groove is semicircle shape, and the circular arc platform diameter R1 is greater than groove diameter R2.
In the present invention, the strengthening rib strip is arc-shaped recess, and the diameter of the strengthening rib strip, which is greater than, to be reinforced
The cup depth of rib.
In the present invention, the bottom of bottle bottom surface is arc-shaped, the side wall of the circular arc platform and the bottom of bottle bottom of arc-shaped
Face is tangent.
In the present invention, the bottom of bottle side wall and bottom of bottle bottom surface are tangent.
In the present invention, the ratio between the groove height H1 and taper platform height H2 are 1:0.69 ~ 0.63.
In the present invention, the combined altitudes of the circular arc platform and bottom of bottle bottom surface nadir are H3, the combined altitudes
The ratio between H3 and taper platform height H2 are 1:0.7 ~ 0.73.
In the present invention, the position that circular arc platform side wall is connect with bottom of bottle bottom surface is arranged in one end of the strengthening rib strip
On, the strengthening rib strip other end successively passes through circular arc platform, taper platform, the face of groove and is centered around the four of protrusion in inside grooves
Zhou Shang.
The utility model has the beneficial effects that there is no claw-like tension groove in the present invention, therefore optimize bottom of bottle bottom surface
The area of contact, while corner being avoided between original technology median claw and pawl to hit recess, be also convenient for bottom of bottle production demoulding and
It is completely nested label on outside the PET beverage bottle body, improves the integrality of bottom of bottle appearance.And in the case where bottom of bottle is by groove
Be provided with circular arc platform, taper platform, strengthening rib strip etc., improve the compressive resistance of bottom of bottle, reach do not crack, the use such as evagination is not wanted
It asks.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing:
Fig. 1 is the structural schematic diagram of the present embodiment；

Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Referring to Fig.1,2,3, a kind of flukeless bottom structure including the groove 2 in bottom of bottle 1, bottom of bottle 1 and is located at 2 center of groove
On protrusion 3, the bottom of bottle 1 includes bottom of bottle bottom surface 11 and the bottom of bottle side wall 12 that is centered around on bottom of bottle bottom surface 11.Further, institute
The lower section for stating groove 2 is equipped with taper platform 4, is equipped with circular arc platform 5 below the taper platform 4, the side wall of the circular arc platform 5 is connected to bottle
On bottom bottom surface 11.At least three strengthening rib strips 6 are evenly equipped in the bottom of bottle 1, and in the present embodiment, then be evenly equipped with six plus
Strengthening tendons item 6.One end of above-mentioned strengthening rib strip 6 is arranged on the position that 5 side wall of circular arc platform is connect with bottom of bottle bottom surface 11, described to add
6 other end of strengthening tendons item successively passes through circular arc platform 5, taper platform 4, the face of groove 2 and the surrounding that protrusion 3 is centered around inside groove 2
On.Further, above-mentioned groove 2, taper platform 4, circular arc platform 5 link position on also each be equipped with easily demoulding transition
