Abstract

The utility model relates to an anti-choke nipple with automatic air inlet. The utility model is characterized in that the nipple seat cushion is provided with an air inlet; the air inlet has the function of the one-way valve. When the air enters the inner cavity of the feeding bottle through the structure, the utility model avoids that the baby holds the nipple when in sucking milk. The water outlet of the nipple is positioned on the both sides of the front end of the nipple, and the water outlet is a linearity opening. The utility model has definite tension. When the nipple is acted by the suction force, the water outlet automatically opens, the suction force disappears, the water outlet automatically closes, and the utility model has the functions of choking prevention and leakage prevention.

Description

Automatic air inlet anti-choke nipple

This utility model relates to the nipple that a kind of infant feeding is used.

Common nipple from present use, the place that has the following disadvantages: the one, the necessary own opening of the nipple of buying back, general method is to open a little hole in the front top of nipple, this little hole is if open the child that easily chokes too much, the too small milk of can not inhaling again of Ruo Kaide, and the time have the excessive phenomenon of spilling leakage of milk to take place, thereby the bad grasp of nipple openings of sizes.The 2nd, the baby can make the phenomenon that produces negative pressure in the feeding bottle and suppress nipple in the process that ceaselessly sucks, thereby makes the baby produce sense of discomfort.

The purpose of this utility model is the nipple that need provide the anti-antiseep of choking of a kind of safe automatic air inlet with the baby that feeding bottle is breast-feeded for vast, and it can effectively overcome the shortcoming that conventional nipple exists.

The purpose of this utility model is to realize like this, at first respectively have a symmetrical linear opening in nipple front end both sides, the oblique the place ahead of opening direction, it is shaped as " ∩ " shape or " 1 " shape or serpentine or " () " shape and arc etc., its opening length can be manufactured material classification different with thickness (being the elasticity difference) and the shape difference of opening is calculated according to nipple, generally be 3～5mm, the main purpose of doing like this is control milk discharge and flow velocity, makes it to reach a desired level.Because the opening of nipple is positioned at nipple front end both sides, milk can flow to the both sides, oral cavity and swallows then into esophagus when the baby sucked, and can not head direct for the throat child that chokes because of milk like this.In addition, the opening of this nipple is linear opening, opening has certain tension force, having only when the baby sucks could breakdown, suction this linearity opening that in a single day disappears will be closed automatically with the tension force of self, so just can guarantee the baby whenever have a suck of this linear opening of milk just automatically breakdown once, every pharynx a bite this linear opening of suckling will be closed automatically, thereby reduced the chance that the baby is choked more, also reduced baby oral cavity burden.

In addition, an air inlet is arranged on the nipple seat cushion, this air inlet also is linear opening, feeding bottle has covered the equidistant ventilative aperture of a circle, when the linear opening on the nipple seat cushion is corresponding with the ventilative aperture on the bottle cap, just constitute one-way valve structures, this valve communicates with the feeding bottle inner chamber, makes when the baby sucks that generation is during negative pressure in the bottle, and this linear opening opens automatically, air just can enter in the bottle through open linear opening by the air-vent on the bottle cap, when stopping to suck, this linear opening is closed automatically, has so just solved the phenomenon of suppressing nipple, and the milk in the feeding bottle can spill and leakage yet, feeds the baby with milk and can obviously feel convenient and easy with this nipple.

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is milk bottle cap front air inlet sketch map.

Fig. 2 is nipple outlet and air inlet sketch map.

Feeding bottle has covered the equidistant ventilative aperture 1 of a circle, respectively there is a symmetrical linear opening 2 nipple front end both sides, this opening has certain force of strain, have only and when being subjected to certain external suction, just can open this mouthful, external suction is in case disappear, this opening can be closed automatically, a linear opening 3 is also arranged on the nipple seat cushion in addition, when the air-vent that covers when this opening and feeding bottle is corresponding, just constituted an one-way valve structures, when producing negative pressure in the feeding bottle, air just can enter the feeding bottle inner chamber through this opening by the spilehole on the bottle cap.

Claims

1, a kind of automatic air inlet Anti-choking nipple of feeding bottle is characterized in that unidirectional air inlet is arranged on the nipple seat cushion, and the outlet of nipple is positioned at nipple front end side.

2, device according to claim 1 is characterized in that the air inlet on the nipple seat cushion is linear opening, and can communicate with the feeding bottle inner chamber.

3, device according to claim 1 is characterized in that the outlet of nipple has two, and symmetry is positioned at nipple front end both sides, and these two outlets are linear opening.
