Abstract

The utility model discloses a piston type flatulence resistant milk bottle. The utility model is designed in order to solve the problem of the prior piston type milk bottle that the infant is flatulent due to milk sucking. The piston type flatulence resistant milk bottle of the utility model comprises a bottle, a reductive bottle mouth at the top end of the bottle is provided with an external thread, the external thread is screwed with an internal thread containing a nipple sleeve cover, a plug-in opening is arranged at the bottle bottom end of the bottle, a piston is matched and embedded in the plug-in opening, a bulge matched with the shape of the inner wall of the reductive bottle mouth is arranged at the top end of the piston. With the structure, when the infant sucks the nipple and the piston reaches at the reductive bottle mouth, because the bulge matched with the shape of the inner wall of the reductive bottle mouth is arranged at the top end of the piston, can embed into the reductive bottle mouth, ensuring no air in the bottle and not causing the flatulence of the infant.

Description

Piston type is prevented the flatulence feeding bottle

Technical field

This utility model relates to a kind of feeding bottle, is meant a kind of piston type feeding bottle of automatic extruding especially.

Background technology

Existing a kind of automatic squash type feeding bottle is to be built-in with a discoid piston at a feeding bottle, and the bottom interlocking has a bottom, and the top interlocking has the upper shield of nipple; Like this, when the baby sucks, cause bottle internal gas pressure to descend, by the effect of atmospheric pressure, bottle outer air pressure will promote piston and slide to bottleneck at the bottom of bottle, reach in the bottle and the balance of bottle outer air pressure, it is very smooth and easy that the baby is sucked, and the feeding bottle of this structure has obtained general application.But because feeding bottle has the bottleneck of dwindling usually, when piston was sliding into this and dwindles bottleneck, the slip that can not make progress again made baby's gas of requiring great effort very much that sucks, and entered air easily and produce bubble in feeding bottle, made the baby suck air and caused flatulence.

The utility model content

In order to overcome above-mentioned defective and deficiency, the purpose of this utility model is to provide a kind of piston type to prevent the flatulence feeding bottle, can prevent to cause the baby to produce flatulence owing to sucking, and the baby suck more laborsaving.

In order to achieve the above object, the anti-flatulence feeding bottle of the piston type that this utility model provides comprises: a bottle, the vertical bottleneck that dwindles of described bottle is provided with an external screw thread, described external screw thread and one has a female thread bolt of the upper shield of nipple, be provided with one in described bottle bottom and fill in mouth, describedly fill in the suitable piston that is embedded with in the mouth, described piston tip is provided with and dwindles the suitable projection of bottleneck inner wall shape.

After adopting above-mentioned structure, utilize the piston of a given shape to insert by the bottom of feeding bottle, the top of this piston is provided with one and dwindles the suitable projection of eck inwall with feeding bottle, can allow fully liquid is fully siphoned away in the feeding bottle, compared with prior art, the projection that increases not only makes the more leicht fallen D/A that sucks, also inhale less than air simultaneously, do not have in the air admission feeding bottle in the process owing to suck, can in feeding bottle, not produce bubble, so can prevent effectively that the baby from producing flatulence by sucking, health is had very great help.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As shown in Figures 1 to 4, be the anti-flatulence feeding bottle of a kind of piston type of this utility model, has a bottle 10, the bottle 10 vertical bottlenecks 11 that dwindle are provided with an external screw thread 15, this external screw thread 15 and one has a female thread 16 bolts of the upper shield 13 of nipple 14, be provided with one in bottle 10 bottoms and fill in mouth 12, by filling in the suitable piston 20 that is embedded with in mouthfuls 12, the top of piston 20 is provided with and dwindles the suitable projection of bottleneck inner wall shape 21, during milk-sucting nozzle 14, external pressure promotes piston 20 naturally and moves, when piston reaches when dwindling bottleneck 11, the projection 21 that the top of piston 20 is provided with is deep into the inside that dwindles bottleneck, and the liquid in the bottle 10 is pushed fully.

As further preferred, on the projection 21 of the top of piston 20 setting, also be provided with one and the suitable protuberance of nipple 14 inner wall shape, the liquid in the feeding bottle is fully siphoned away.

Structure in sum, this utility model utilization cooperates the piston with a projection and protuberance that dwindles bottleneck and nipple, and product loses push effect completely, the liquid in can the extinction feeding bottle, and the person of smoking takes little effort, lacking of the interior liquid residue of feeding bottle, feeding bottle is cleaned easily, and in the process that sucks, do not have in the air admission feeding bottle, can in feeding bottle, not produce bubble, this utility model can not allow the person of sucking produce flatulence, make for good health, so can provide good usability.

The above is the detailed description of preferred embodiment of the present utility model, is not to be used for limiting this utility model, and the embodiment of all its similar variations and proximate structure all should be covered by in the protection domain that this utility model claims are defined.

Claims

1, the anti-flatulence feeding bottle of a kind of piston type, comprise a bottle, the vertical bottleneck that dwindles of described bottle is provided with an external screw thread, described external screw thread and one has a female thread bolt of the upper shield of nipple, be provided with one in described bottle bottom and fill in mouth, describedly fill in the suitable piston that is embedded with in the mouth, it is characterized in that described piston tip is provided with and dwindles the suitable projection of bottleneck inner wall shape.

2, according to the anti-flatulence feeding bottle of the described piston type of claim 1, it is characterized in that, also be provided with a protuberance suitable on the described projection with the nipple inner wall shape.
