Description

The feeding bottle of vomit milk prevention

Technical field

This utility model relates to a kind of feeding bottle, more specifically to a kind of bottle inside and outside air pressure balance that can guarantee feeding bottle, prevents infantile vomiting milk, can also avoid the feeding bottle of the vomit milk prevention in the milk in the outer air admission feeding bottle of bottle simultaneously.

Background technology

Feeding bottle is the ware commonly used of infant, and the present normally used infant feeding bottle of China comprises that the bottle of glass or plastic material, the milk that is installed in bottle upper end bottleneck are chewed, gland and protective cover, and milk is chewed and had the mouth that sucks.The milk of existing infant feeding bottle is chewed with bottleneck and is taked totally enclosed mode, and when infant was sucked milk, the milk in the bottle reduced gradually, space in the bottle increases accordingly, the bottle inner air pressure descends gradually, and bottle outer air pressure is higher than pressure of the inside of a bottle, can produce negative pressure, in the time of in air can't enter bottle from nipple, make the milk can not sucking-off, cause the difficulty that continues to suck, the milk volume flow instability, even nipple occurs and inhaled flat phenomenon, influenced normal nurture.At this moment have only the air of allowing to enter in the bottle, thereby the balance negative pressure could continue to suck from sucking the hole.So not only make troubles, and make infant be forced to suck a large amount of air, spitting milk, the phenomenons such as milk, hiccough of choking take place, influence the appetite of infant, and cause symptoms such as infant flatulence, spitting milk, stomachache, otitis media easily to the adult.Use this feeding bottle nurture to waste time and energy, and because air can enter feeding bottle from the mouth that sucks, and baby's part saliva also can be along with the air admission feeding bottle, these mouthfuls water and air contact with the intravital milk of bottle, influence the quality of milk easily, and be very unhygienic.Therefore milk must finish off at once, in case it is just apt to deteriorate to place the time milk of growing a bit a little, can't drinks to the baby once more, otherwise also might cause the baby sick.

In order to solve the problem that the baby sucks air, someone improves general feeding bottle, as Chinese patent literature CN2067569 " the anti-sanitation feeding bottle of choking of may command flow ", the anti-sanitation feeding bottle of choking of a kind of may command flow is disclosed, form by common feeding bottle, nipple with by the air permeable disc of air-vent, the sebific duct and the protective cover that have a may command flow stainless steel ball, because the sebific duct of action of gravity band stainless steel ball is always fallen extreme lower position in the bottle, no matter what all exhaust to contain milk in the bottle, no matter the baby is seated, recumbency, any attitude all can be sucked freely.

But the feeding bottle of this structure is just changed to the mouth that sucks that the air-vent of feeding bottle is chewed from original milk on the air permeable disc, air still can enter feeding bottle from the mouth that sucks, pollute milk, and the sebific duct that it is found that the band stainless steel ball in actual use bends easily, milk is difficult to by the sebific duct bending place, causes the baby to be difficult to be drawn onto milk.

Chinese patent literature CN2180254 " baby health-care feeding bottle " then is inside and outside feeding bottle is installed communicating pipe connection feeding bottle, plays the purpose that guarantees air pressure balance, and its shortcoming is that air still can enter feeding bottle from the mouth that sucks, and pollutes milk.

Summary of the invention

The purpose of this utility model is that prior art is improved, and a kind of feeding bottle of vomit milk prevention is provided, and can avoid in the milk in the outer air admission feeding bottle of bottle under the prerequisite of the bottle inside and outside air pressure balance that guarantees feeding bottle, and the technical scheme of employing is as follows:

The feeding bottle of vomit milk prevention of the present utility model, comprise that bottle, milk are chewed, gland and protective cover, milk is chewed, gland and protective cover are installed in bottle upper end bottle mouth position, milk is chewed and is had the mouth that sucks, it is characterized in that: also comprise flexible inner bag, the opening of flexible inner bag is equipped with bracing ring, and the external diameter of bracing ring has air-vent greater than the internal diameter of bottleneck on the sidewall of bottle.When infant is sucked milk when chewing, the mouth that sucks that milk is chewed by milk from flexible inner bag is sucked away, the pressure of flexible inner bag reduces, the intravital pressure of bottle also reduces, therefore air enters in the bottle from air-vent, makes the bottle internal pressure keep identical with extraneous, and the compressing flexible inner bag, make the volume-diminished of flexible inner bag, the pressure in flexible inner bag is also with till the pressure on the inside and outside boundary of bottle is consistent.Owing to adopted flexible inner bag, the elastic force of flexible inner bag is little, therefore flexible inner bag is understood reduced volume under the pressure effect in the external world after internal pressure reduces, and Wai Jie air can not enter flexible inner bag from the mouth that sucks like this, guaranteed the health of milk in the flexible inner bag, and the cost of flexible inner bag is low, can be disposable therefore, and using the back flexible inner bag can abandon, much cleaner, be particularly useful for the user out using.

A kind of scheme preferably, the external diameter of described bracing ring is less than or equal to the external diameter of bottleneck.Gland is not easy to run into bracing ring like this, causes bracing ring to damage.

In order to allow bottle can be used for weighing milk, described air-vent is positioned at the top side wall of bottle.Because flexible inner bag weighing milk is inaccurate, therefore come weighing milk proper with bottle, if the position of air-vent is lower, the bottle that is higher than air-vent just can't be used for weighing milk, otherwise milk can spill bottle from air-vent, therefore the amount of the milk that bottle can weighing is just smaller, is difficult to satisfy the demands.With the set positions of the air-vent top side wall to bottle, then the bottle part of air-vent below can be used for weighing milk, just can utilize the most volume of bottle to come weighing milk fully.

For the ease of weighing milk, described bottle lateral wall is provided with a plurality of scales.

This utility model beneficial effect against existing technologies is to avoid can not polluting the milk in the feeding bottle in the milk in the outer air admission feeding bottle of bottle under the prerequisite of the bottle inside and outside air pressure balance that guarantees feeding bottle; And air-vent is set to the top side wall that is positioned at bottle, then can utilize the most volume of bottle to come weighing milk fully.
