Another problem that the tradition feeding bottle exists is: nipple is screwed on the feeding bottle by the screw-on collar, the nipple circumferential edges is fixed on the milk bottleneck by spiral cover and realizes sealing; baby sometimes uses tooth and stings nipple and pull; the marginal portion of using bigger strength may pull nipple or nipple is drawn out; liquid will seepage in the bottle; influence baby and have milk, the clothes of also can making dirty causes much unnecessary troubles.

Summary of the invention

At the defective that exists in the technique scheme, the object of the present invention is to provide a kind of feeding bottle of taking back the aspiration base, can solve feeding bottle return-air problem, keep bottle internal pressure balance, can also prevent that nipple from being pulled at by baby tears off, the process that makes baby have milk is smooth and easy, approaches to suck breast milk.

Above-mentioned purpose is achieved through the following technical solutions:

A kind of feeding bottle of taking back the aspiration base, include bottle, nipple, the rotary collar, suction pipe seat, it is characterized in that: described suction pipe seat surface cylindrical is provided with many group muscle ribs, the muscle rib is corresponding bottom nipple, the suction pipe seat surface is provided with corresponding to annular protrusion round in the nipple bottom and that seal, be concaved with an annular return-air groove between annular protrusion and the suction pipe seat surface cylindrical, be provided with the air inlet of perforation in the bottom of return-air groove, be provided with the fluid passage of a perforation in the inside center of annular protrusion.

Described muscle rib is formed by the sawtooth assembled arrangement of many groups projection, and is gapped between the sawtooth.

In described every group of muscle rib, the height of middle sawtooth is lower than peripheral sawtooth height.

Described air inlet lower end is provided with a cylinder silica gel check valve.

Has a sealed step on the described annular protrusion, in order to circle in the sealing nipple bottom.

Described fluid passage lower end is connected with suction pipe, and the other end of suction pipe is connected with the suction nozzle with weight.

Described bottle is provided with one and has externally threaded bottleneck at the top, can make nipple be maintained on the bottle for the bottle cap screwing of perforation in the middle of tapped.

Adopt above-mentioned structure design, cylindrical is provided with many muscle ribs on the suction pipe seat surface, after nipple bottom and suction pipe seat correspondence, be tightened on the bottleneck with the rotary collar again, promptly finished whole combination, at this moment, soft nipple bottom inner circle is sealed by the annular protrusion of suction pipe seat, the corresponding back of muscle rib and nipple bottom is because the gap that exists between the sawtooth of every group of muscle rib, air outside is entered in the return-air groove on suction pipe seat surface, enter in the bottle by check valve through air inlet again, reach the equilibrated effect of the intravital air pressure of bottle of keeping.Aforesaid way has been abandoned the technical scheme that return-air hole is set fully on the nipple body of flexible material, reach same purpose in another kind of return-air mode, and simple in structure, easy to process.

In addition, because cylindrical is provided with many muscle ribs on the suction pipe seat surface, after nipple bottom and suction pipe seat correspondence, be tightened on the bottleneck with the rotary collar again, make between nipple bottom and the bottleneck very fasteningly, baby promptly uses tooth to sting and firmly pull nipple, and nipple can not come off, more safer than common feeding bottle, more practical.
