Abstract

The utility model discloses a feeding bottle with a U-tube for adjusting air supplement, which is the milk feeding appliance for infants. The feeding bottle with a U-tube for adjusting air supplement is composed of a U-tube which is added on an ordinary feeding bottle composed of a bottle body, a cap and a nipple and crosses the bottle body wall portion, and a regulating system composed of the U-tube and a regulating sleeve. When in milk feeding, so long as the regulating sleeve is slightly pushed, the purpose of regulating air supplement can be achieved.

Description

Feeding bottle with U-tube for adjusting air supplement

The present invention relates to a kind of improved Infantile nursing bottle.Particularly a kind of feeding bottle of regulating air inflow.

Existing feeding bottle is by bottle, lid, nipple or only be made up of bottle, nipple.What sell on the market is exactly this form.When sucking, as long as nipple is put into the infant mouth, then fall tilting bottle, infant can suck.But, in the process that sucks with existing feeding bottle, usually the appearance of discontinuity choke milk phenomenon.In addition, it is investigated that patent documentation learns that an existing invention that overcomes the above problems patents.Title is: " the adjustable feeding bottle of air inflow ".Its structure more complicated is unfavorable for again using.

Task of the present invention is that a kind of improved Infantile nursing bottle will be provided.The milk problem of choking more than it can solve simply.

Task of the present invention is finished as follows: inside and outside bottle cap and milk are adorned UNICOM's bottle on the nozzle assembly, and the thin U-shaped pipe of the bottle wall portion that jumps.The seam of bottle cap and milk nozzle assembly and U-shaped pipe outer wall should be closely connected.The regulating sleeve of regulating air inflow is equipped with in the end that is exposed at the outer U-shaped pipe of bottle.The end of the intravital U-shaped pipe of bottle is flat mouthful.When feeding bottle is filled milk; When regulating sleeve is open mode, also be full of milk in one section U-shaped pipe in the bottle.And because capillarity, the liquid level in the pipe is higher than the liquid level in the bottle.When the bottle inversion was breast-feeded, inner and outer air pressure should keep equilibrated trend.So, being detained the milk in the pipe, can not move toward bottle is outer.And along with the continuation that sucks, the appearance of inner small and outside big pressure difference makes the gas of outside to move in bottle.Thereby the milk that promotes to be detained in the pipe is emerged in bottle.At this moment the U-shaped pipe has just become a gas passage, and the quantitative gas of supply in bottle reduces or the interior negative pressure of counteracting bottle.

The present invention only will increase by three little parts in addition when adopting following example structure, and cost does not almost increase.

Below with reference to accompanying drawing invention is described in further detail.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the present invention.

Fig. 2 is along the cutaway view of 1-1 line among Fig. 1.

With reference to Fig. 1, the union elbow of U-shaped pipe part and lid " 7 " cast solid.Outer tube " 4 " joins with the outer hole " 6 " of lid " 7 ".Interior pipe " 5 " joins with the endoporus " 9 " of lid " 7 ".Lid " 7 " is with moulding when casting, and cross-drilled hole molding mouth " 8 " seals with thermal source, with keep the U-shaped pipe along logical.Regulating sleeve " 2 " is enclosed within the afterbody of outer tube " 4 ".The length of regulating sleeve " 2 " should be less than the length of the breach " 3 " of outer tube " 4 ".The hair step that withdraws from prevention regulating sleeve " 2 " is pressed in the end of outer tube " 4 " with thermal source.Outer tube " 4 " preferably adopts plastics to make.Regulating sleeve preferably as shown in Figure 2 the plastics of cross sectional shape make.Middle partly should being longer than among the 1～2mm(figure of outer ring do not outpour).Nipple " 10 " is made with rubber.Nipple " 10 " cooperates with interior pipe " 5 " external diameter, should guarantee non-leakage liquid.Bottle " 1 " is made by transparent material, and milk what are used to observe.
