Description

The feeding bottle air return system

Technical field

The relevant a kind of feeding bottle parts of this utility model relate to specifically and a kind ofly are used for the feeding bottle return-air so that the external and internal pressure of baby child's feeding bottle when sucking with feeding bottle can reach the feeding bottle air return system of dynamic equilibrium.

Background technology

Feeding bottle generally uses in the virgin developmental process of baby.In the use of feeding bottle, when baby child sucked milk power solution by nipple, along with the minimizing of solution in the bottle, the air pressure in the feeding bottle a bottle interior vacuum can occur less than the outer air pressure of bottle, and baby child has milk the situation of effort.In general nipple uses, owing to when baby child sucks milk by nipple, cause the feeding bottle external and internal pressure poor, air enters in the bottle by face, return-air hole, nipple, the bubble formation flatulence that makes air dissolve in producing in milk powder and the water, make baby suck milk and suck air and cause paroxysmal enterospasm and stomachache, make the baby can occur vomitting milk, beat every etc. bad problem.

There is a kind of air return system at present, forms with two parts of airway, covered one or two return-air hole, can reach some return-air effects at return-air by the return-air lid.But this air return system exists two bad leak: a, a return-air hole or two return-air holes, only can be at the position of return-air hole return-air, and the return-air effect is received influence; B, difficult sterilization or purging system spot, unhygienic.

The utility model content

The purpose of this utility model is at the problems referred to above, provides a kind of simple in structure, and return-air is effective, the feeding bottle air return system of easy cleaning.

For achieving the above object, this utility model adopts following technical scheme:

A kind of feeding bottle air return system comprises return-air lid and airway, and described return-air lid comprises:

One loam cake, this loam cake along the circumferential direction is provided with at least two outlet holes, and this outlet hole edge extends to form at least two first passages downwards;

One lower cover, be provided with into milk hole at this lower cover periphery with the described corresponding position, hole of advancing to suckle, this bore edges that advances to suckle extends upward the formation second channel, this second channel and first passage closely cooperate and form the milk passage, form gas channel in this passage outer space that goes out to suckle, and described lower cover periphery extends upward formation one annular lip, on this annular lip, have at least two return-air mouths, in the middle of this lower cover downside, be convexly equipped with a boss downwards, be provided with passage at this boss center, this passage is communicated with described gas channel;

Described airway is socketed on described boss.

Preferably, the outlet hole of described loam cake is three, is shaped as arc and evenly setting along the circumferential direction.

Preferably, described return-air mouth quantity is three, is arranged on the position of corresponding described gas channel.

As a kind of selection, can under this lower cover, be provided with annular caulking groove by side periphery, be used for the feeding bottle bottleneck chimeric.

As a kind of selection, also can be provided with a cylinder at described boss center, described passage is positioned at described cylindrical center.

As a kind of selection, described boss comprises central cylinder and around this cylindrical ring wall, described passage is positioned at described cylindrical center, and described airway is enclosed within the described ring wall outside.

Preferably, described airway has one and is used for and a belled wide diameter end of described ring wall and a thin footpath end, has slotted eye at this thin footpath end.

Compared with prior art, feeding bottle air return system of the present utility model is in communication with the outside owing to forming venting channels and revolve mouth by return-air mouth and feeding bottle in the passage outside that goes out to suckle, return-air can be back to the bottle bottom of feeding bottle along venting channels, airway, avoid air dissolves in water, to form flatulence, and cause baby child occur vomitting milk, beat every etc. bad problem, and return-air mouth and venting channels form around return-air, and the recipient is not to restriction for its return-air, and return-air is effective; And the return-air lid is combined by loam cake and lower cover, and the two can be dismantled, and it cleans convenient, more health.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Shown in Figure 1 is a kind of feeding bottle air return system of this utility model, comprise return-air lid and airway 30, described return-air lid comprises: a loam cake 10, this loam cake along the circumferential direction is provided with three outlet holes, outlet hole is shaped as arc and along the circumferential direction evenly is provided with, and this outlet hole edge extends to form at least two first passages 11 downwards.

Described return-air lid also comprises a lower cover 20, referring to Fig. 1 and Fig. 2, be provided with three holes of advancing to suckle at this lower cover periphery with the described corresponding position, hole of advancing to suckle, this bore edges that advances to suckle extends upward and forms second channel 21, this second channel 21 closely cooperates with first passage 11 and forms the milk passage, form gas channel 22 in this passage outer space that goes out to suckle, and described lower cover 20 peripheries extend upward formation one annular lip 23, have three return-air mouths 24 on this annular lip 23, this return-air mouth 24 is arranged on the position of corresponding described gas channel 22.Be convexly equipped with a boss 25 downwards in the middle of these lower cover 20 downsides, be provided with passage 26 at these boss 25 centers, this passage 26 is communicated with described gas channel 22.Described airway 10 is socketed on described boss 25.

Be provided with annular caulking groove 27 at 20 times side peripheries of lower cover, be used for the feeding bottle bottleneck chimericly,, prevent that milk is excessive so that better seal bottleneck.

As shown in Figure 1, also can be provided with a cylinder 28 at described boss 25 centers, described passage 26 is positioned at the center of described cylinder 28, and the milk that this cylinder 28 can be avoided entering airway 10 when sucking enters passage 26 again, and influences return-air.Described boss 25 also can comprise central cylinder 28 and around this cylindrical ring wall (figure does not show), described passage 26 is positioned at the center of described cylinder 28, and described airway 30 is enclosed within the described ring wall outside.

Described airway 30 has one and is used for holding 32 with described boss 25 belled wide diameter ends 31 and a thin footpath, holds 32 to have slotted eye 33 in this thin footpath.This wide diameter end 31 is outside being enclosed within boss 25 time, near boss, form collection chamber, avoiding sucking more for a long time baby child produces bigger pressure oscillation in feeding bottle, can store a part flows into airway 10 when the reversing feeding bottle milk simultaneously, avoids milk to enter passage 26.Thin footpath holds 32 to be used to derive air, even at the bottom of its slotted eye of offering 33 can guarantee that thin footpath holds 32 to touch bottle, still can reliably air be imported.

Fig. 3 is the installation diagram of feeding bottle.Loam cake 10, lower cover 20 and airway 30 are installed together successively in Fig. 3, reinstall feeding bottle 40 bottlenecks, are compressed by feeding bottle spiral cover 60.When baby child sucked, milk flowed out through nipple 50 from the passage that goes out to suckle of upper and lower covers; And air enters from the mouth that revolves between feeding bottle spiral cover 60 and the feeding bottle 40, and cooled via return air mouth 24, gas channel 22 and airway 10 flow into the position, bottle bottom of feeding bottles 40, the smooth and easy outflow of assurance milk.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
