Description

Telescopic nipple is extended in the tool air inlet

Technical field

This utility model relates to a kind of tool air inlet and extends telescopic nipple, is at the architecture advances of feeding bottle with nipple.

Background technology

Feeding bottle utilizes the locking closure lock to be contained in the imitative nipple as if parent breast type of feeding bottle epimere, supplies containing food and sucking of child's mouth, is a main apparatus of finishing the interior liquid storage of absorption bottle.And this nipple is when being sucked by the child, mends an amount of air by the feeding bottle bottle is outer, will cause the inside and outside pressure disequilibrium of bottle, causes liquid storage to be sucked discharge smoothly.Nipple hypomere or position, stage casing are to be equipped with intake valve, after by locking closure nipple being locked together in above the feeding bottle bottleneck, at nipple by the process of sucking, in the time of with the liquid storage sucking-off, promptly introduce an amount of bottle outer air automatically, enter the feeding bottle inner segment via this air inlet valve position, carry out the balance and the compensating action of pressure.

Yet, sucked in the process because of nipple, can be that the place, feed flow aisle of its inner segment forms the powerful liquid storage absorption district of suction; So be positioned at the bottle outer air that the place, air inlet seam hole of peripheral part, feed flow aisle imports, will be because of being in feed flow aisle periphery, and the air capacity of some is naturally again with being sucked out the outer liquid storage of bottle by the while sucking-off, and with the row that returns enter child's abdominal part, and then cause its abdominal bloating, discomfort, and the painful hard to bear phenomenon of crying and screaming is arranged, this is the common situation in infant feed back.

For at head it off, a kind of scheme of improving nipple structure has been proposed, mainly be that the intake valve of nipple bottom surface is used the extension setting that protrudes out pipe downwards, make the initial position of bottle external admission in entering feeding bottle, break away from below, nipple inner segment feed flow aisle; Though so can avoid air inlet to be sucked immediately, and prevent that it from returning row with liquid storage and entering nipple, infiltrates and cause abdominal part flatulence phenomenon in child's abdomen; But usually feeding bottle is tilting state, and this only has the pipe that protrudes out in single orientation, and is more because of the amount of banking up of liquid storage in the bottle if gone to the end during fragment position, and the basic shortcoming that pressure is big, fluid has some setbacks is promptly arranged; And quality far is lighter than the air inlet of liquid storage, because of being that vertical direction rises, so is close to the main liquid storage suction zone in stage casing, rear, feed flow aisle on the contrary, still has to incorporate in the liquid storage possibility that is sucked out, causes flatulence.

Therefore, in protrude out the nipple of tubular type intake valve, if will reach preferable anti-flatulence effect, then be this must be protruded out when pipe goes to fragment position to use; At this moment, because of the liquid storage amount of banking up in the bottle less, and have that pressure is less, fluid effect more smoothly; And, when the air inlet vertical direction rises, because of near liquid storage liquid level epimere, and can be very fast incorporate the interior air entrapment of original bottle.But, because of this protrudes out the set shortcoming in the single orientation of pipe, align up and continue use, in fact its difficulty and inconvenience are arranged.

And, be dissolved into liquid storage L problem at above-mentioned bottle external admission AIR, people have developed between cover of a feeding bottle nipple (middle section apparatus nipple) and feeding bottle bottleneck, increase by the one group of isolated air inlet pipe of packing in addition, in order to being extended, the bottle external admission causes position, feeding bottle bottle bottom technical scheme (as U.S. patent of invention US5779071, Nursing bottle with an air venting structure and U.S. Pat 5570796, Nursing bottle with an air venting structure); Though the intended purposes of its structure has its superiority; But because of such is independent, other adorns and the complicated structure of isolated air inlet pipe of several assemblies of must arranging in pairs or groups, except that causing the operational inconvenience of product manufacturing, assembling and use, and its specialized purpose-build can't be implemented in general common-use size feeding bottle, nipple collocation, promptly causes obviously improving in manufacturing cost; The process that is mutually locked of the mutual socket of these several assemblies and collocation feeding bottle, nipple, cover of a feeding bottle nipple particularly, difficulty can be got rid of in the sealing bottles fully, prevents the phenomenon of accidental gas leakage, and will make it implement to go up suitable inconvenience.

Summary of the invention

This utility model main purpose provides a kind of tool air inlet and extends telescopic nipple; It is the inner segment running-on of nipple, is positioned at the inner side edge place of milk gonys section intake valve, is provided with the downward extension sleeve pipe that is formed in one with nipple; The bottle outer air that nipple hypomere air inlet valve position is imported, be telescopic insulating effect to be set via this elongation downwards, air inlet is extended to breaking away from more far-reaching position, bottleneck position, and select automatically preferentially to enter in the feeding bottle and replenish by its mesolow place, reach the liquid storage suction zone of avoiding place, nipple inner segment feed flow aisle, and then the bottle external admission that effectively prevents from just to be imported into again with liquid storage in the bottle by the while sucking-off, guarantee that child's imbibition is smooth and easy and reach, with the abdominal bloating phenomenon that prevents its improper suction air.

This utility model time purpose provides a kind of tool air inlet and extends telescopic nipple; Wherein, remove described nipple inner segment running-on, be positioned at the inner side edge place of milk gonys section intake valve, set being equipped with outside the downward extension sleeve pipe position that is formed in one with nipple; Structure positions such as the mouth body of all the other nipples and intake valve, locating ring all need not have any difference with the conventional nipple structure; So can have and not change the easiest operating effect that nipple assembling, use and child suck custom etc. fully, and have simultaneously easy to make, inexpensive, clean and be easy to multiple practicality.
