Abstract

The utility model relates to a nipple, which is a nipple that can prevent the child from inflating due to the air suction by improving the air inlet structure of the nipple. The nipple is hollow inverted funnel type, the lower side surface of the flange at the bottom end of the nipple is provided with a push-pull type protruding pipe which is integrally formed with the nipple, the top end of the protruding pipe is opened on the flange of the nipple, the tail end of the protruding pipe is closed, but a split hole connected to the hole of the protruding pipe is longitudinally cut at the middle section. The nipple is normally closed, the crack hole is closed, air is not fed, and juice can be prevented from entering the tube; when the nipple is sucked, the air outside the bottle is introduced into the protruding pipe under normal pressure and pushes away the crack hole to be filled into the bottle, so that the air pressure inside and outside the bottle is balanced. Ensure that the infant does not inhale the air in the bottle.

Description

A kind of nipple that can effectively prevent flatulence

This utility model relates to a kind of infant article, relates to a kind of feeding bottle or rather, particularly a kind of nipple structure that can effectively prevent flatulence.

Feeding bottle is the main tool of slops such as infant feed fruit juice, milk, comprises that bottle and interlocking supply the infant mouth to contain and suck the also maltha hollow nipple of falling the funnel type of its liquid outlet quantity of may command on the bottle top.The feeding bottle nipple is mainly finished the fluid function, and the action of infant by containing food, sucking nipple makes juice, liquid in the feeding bottle flow out through the liquid outlet of nipple front end.Along with the discharge gradually of juice, liquid in the feeding bottle, air chamber strengthens in the bottle, and air pressure reduces relatively, imports air as if untimely outward by bottle, then can stop the continuation of a bottle interior juice, liquid to be discharged because of the adsorption of air pressure, makes infant suck difficulty.

One of solution to the problems described above is to establish on the nipple together or above together air inlet, makes nipple can introduce the outer equal-volume air of bottle simultaneously in the fluid process, makes a bottle interior supercharging reach air pressure balance, and assurance juice, liquid are stablized, sucking-off constantly.

The conventional nipple structure as shown in Figure 1, the air inlet 11 of nipple 1 is arranged on the end section flange 12 of mouth body, be positioned at mouth bottom section edge and lack each concavity air intake duct 13 below of establishing, and running-on 21 peripheries that pass through feeding bottle locking closure 2 are arrested when overlapping nipple 1 stage casing ring-like indent neck groove 14 location, the fin 22 that is positioned at air inlet 11 outer rims that these locking closure 2 bottom surfaces are set, be pressed against flange 12 tops, form the air inlet aisle 2A of a line, continue with air inlet aisle 2A in running-on 21 that air intake duct 13 extends downwards and the below of the slit 1A between nipple 1 wall body, the child is when sucking liquid continuously, bottle outer air A scurries into slit 1A by air intake duct 13, after folding into air inlet aisle 2A, enter in the bottle by air inlet position again, make a bottle internal and external pressure balance.

The structure of this nipple 1 has following 4 unavoidable shortcomings:

1. requiring has higher precision, all requires below the 1mm as the width of slit 1A, the height of fin 22 etc., and particularly the width of slit 1A with running-on 21 bores of accurate cooperation locking closure 2 and the external diameter of concavity neck groove 14, has increased the difficulty of making;

2. nipple 1 is made by the soft rubber material, in the distortion that is subjected to produce inequality when uneven strength is suppressed, the degree of locking and screwing as locking closure 2, because of individual application of force situation difference has difference on the depth, the press power of the too big generation of locking closure power is also big, makes flange 12 be subjected to over-drastic pressure, causes air inlet aisle 2A to dwindle even complete obiteration (flange 12 end faces and locking closure 2 bottom surfaces are close to), thereby losing function by air intake duct 13 air inlets, this is the modal use shortcoming of this structure nipple;

3. nipple separates usually with feeding bottle and sells, when the nipple of the bottle of consumer's acquisition first brand, adapted second brand, can use mutually though external form, specification are roughly similar, but owing to locking closure 2 running-ons 21 bores, concavity neck groove 14 external diameters and fin 22 height, position etc. eventually can not be identical, and cause difference on the result of use, even forfeiture air inlet function, cause and suck difficulty;

4. enter the interior air A of bottle by air inlet 11, accumulate in the below in nipple 1 fluid aisle 15 in advance, work as juice, when liquid sucked in child's mouth, a little air A can sneak in child's abdomen with juice, liquid, and the child sucks air will cause the flatulence discomfort, causes the child to cry and scream.

The purpose of this utility model is a kind of nipple that can effectively prevent flatulence of design, can safe air inlet and keep stable, fluid swimmingly, and air can not sneaked in child's mouth with juice, liquid, prevents that effectively the child is because of sucking the flatulence that air causes.

A kind of nipple that can effectively prevent flatulence of the present utility model is the hollow flexible glue of falling a funnel type plastid, it is characterized in that:

There is the pushing and drawing shape of endcapped to protrude out pipe with nipple is one-body molded on the flange downside of described nipple bottom, protrudes out the pipe top end opening on nipple flange, protrude out the terminal middle section of pipe and longitudinally dissect and be connected to the ceasma that protrudes out the pipe pore.

Protrude out pipe and sucked at nipple under the normality of masterpiece time spent, the thick compressing of the managed end wall of its ceasma and sealing, not air inlet also can prevent that a bottle interior juice, liquid from entering and protrudes out pipe; When nipple is sucked the power effect when distortion is arranged, the space enlarges between nipple and bottle cap, while being sucked out along with juice, liquid in the bottle, the bottle internal gas pressure reduces, and the outer atmospheric air of bottle is introduced to protrude out in the pore and push ceasma open and replenished in the bottle equilibration flask external and internal pressure, make imbibition stable, smooth and easy, air directly imports depths in the bottle by protruding out pipe, can not accumulate near the fluid aisle of nipple inside, guarantees that the child can not suck a bottle interior air.

Nipple of the present utility model protrudes out pipe and breach is set protruding out the pipe end by extending, and airtight when forming normality, open air inlet when sucking, air replenishes in the feeding bottle through pore, realizes safe air inlet and keeps the effect of stablizing fluid; Protrude out pipe and air is introduced in the no liquid space of feeding bottle depths, the equilibration flask inner and outer air pressure, the place, fluid aisle that can not accumulate in nipple is sneaked in child's mouth with juice, liquid; Nipple bottom flange is that thallus is not afraid of bi-directional compression, and under the big or small application of force effect of locking closure, the problem that does not all have pore to dwindle or disappear all can be stablized, balancedly air inlet.

Referring to Fig. 2, Fig. 3, Fig. 4, end section flange 31 downsides of the hollow nipple of falling the funnel type 3 are one-body molded to have protruding out of pushing and drawing shape to manage 32, and this end that protrudes out pipe 32 is a closed.In vertical ceasma 322 that the useful thin cutter in middle section that protrudes out pipe 32 ends dissects out, this ceasma 322 reaches deeply to the pore 321 that protrudes out pipe 32.This nipple can be assembled with the bottle cap 4 and the bottle 5 of various brands, just can extend certain depth places in the bottle 5 and protrude out pipe 32, as shown in Figure 4.

In conjunction with referring to Fig. 5, pore 321 is under the normality of the broken sucking distortion of nipple 3, the air pressure P inside and outside because of feeding bottle equates, and upward ceasma 322 is very thin to protrude out pipe 32 ends, the thick compressing of managed in addition end wall forms closes shape, so not air inlet, in like manner, juice, liquid can not be entered by the ceasma 322 that closes and protrude out in the pipe 32 in the bottle.

But when sucking nipple 3 makes the wall portion 33 of mouth body produce minor changes, mouth body wall portion 33 enlarges with the space that cooperates of 4 of bottle caps, after adding that juice, liquid W are sucked discharge in the feeding bottle 5, bottle internal gas pressure P reduces, and causes the outer atmospheric air A of bottle to be imported in the pore 321, and pushes ceasma 322 open because of the external force supercharging and clamp-on in the bottle 5, when enough air pressure is arranged in the bottle, this ceasma 322 recovers normally off again automatically, realizes the balanced action of supercharging in the bottle, makes the sucking fluid stablize, continue.Air A directly by protruding out the depths of managing 32 introducing bottles, 5 inside, can not accumulate near the fluid aisle 34 of nipple 3 inside, and can guarantee the unlikely air A that is used as the equilibration flask internal gas pressure in the process of sucking juice, liquid W in the unexpected inspiration importing bottle 5 of child.Because the child can unexpected not suck air A, produces flatulence so can effectively prevent child's abdominal part, air A mends in the bottle fast, swimmingly, and the juice in the bottle also can be fast, outflow swimmingly, and it is laborsaving, light that the child is sucked.

During actual the use, its extent of opening was very tiny when air A pushed ceasma 322 open, air A is the crack with the quick infiltrate ceasma 322 of pressure propulsion mode, naked eyes be difficult to see ceasma 322 moment the opening and closing process and open, closed degree, juice, liquid can't be entered in the pore 321 by the ceasma place in the bottle, and the extent of opening of ceasma 322 has just schematically been amplified among Fig. 5.

Nipple of the present utility model is broken through the many shortcomings in the conventional nipple air intake structure fully, make the child in sucking process, reach the equilibrated function of use of air inlet, really can effectively prevent the ballooning the when child sucks milk, and have simple in structure, be easy to make, be suitable for multiple practicality such as specification is many.
