Description

The feeding bottle of a kind of bottom return-air

Technical field

This utility model relates to the feeding bottle of a kind of bottom return-air.

Background technology

The gas returning port of existing feeding bottle is generally arranged on nipple, and close to outlet hole, the air entered from gas returning port is easily drawn to outlet hole and then is sucked in abdomen by child by child when having milk, and causes child to rise the phenomenon of tripe and spitting milk; Meanwhile, existing feeding bottle mostly adopts plastics body, easily separates out harmful substance, be not easy to growing up healthy and sound of child under high temperature soaks.For this reason, be necessary to carry out structural Curve guide impeller to existing feeding bottle.

Utility model content

In order to solve the problem, this utility model provides the feeding bottle of a kind of bottom return-air.

This utility model solves the technical scheme that its technical problem adopts:

A feeding bottle for bottom return-air, comprises body and has at the bottom of elastic bag, and for wrapping up bottom body, be provided with through hole bottom described body, at the bottom of described bag, the position of corresponding through hole is provided with check valve at the bag end.

Described body is provided with an annular groove in its sidepiece lower end.

In tubbiness at the bottom of described bag, its top open part cross-sectional area is less than bottom.

Bottom inside at the bottom of described bag is provided with a location sealing post upwardly, and location sealing post comprises a bottom, in truncated cone-shaped in tubular middle part with a top in truncated cone-shaped, and mid diameter is minimum; Be provided with an air inlet in location sealing post, this air inlet extends at bag the end, and described check valve is arranged in air inlet; Described through hole and location sealing post match.

Described body adopts glass material to make.

The beneficial effects of the utility model are: adopt this utility model of said structure by arranging at the bottom of through hole and bag bottom body, realize when feeding bottle uses from return-air bottom body, the situation can thoroughly avoiding child to suck air when sucking the breast occurs, and prevents child to rise tripe or spitting milk.This utility model is simple and practical, Be very effective.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, this utility model is further illustrated:

Fig. 1 is schematic diagram of the present utility model;

Fig. 2 is decomposing schematic representation of the present utility model;

Fig. 3 is generalized section of the present utility model.

Detailed description of the invention

With reference to Fig. 1 ~ Fig. 3, this utility model is the feeding bottle of a kind of bottom return-air, and comprise body 1 and to have at the bottom of elastic bag 2, the bag end 2, for wrapping up bottom body 1, is provided with through hole bottom body 1, and, the position of corresponding through hole is provided with check valve 4 at bag the end 2; Body 1 adopts glass material to make, and makes body 1 in use can not separate out harmful substance.Adopting this utility model of said structure by arranging at the bottom of through hole and bag 2 bottom body 1, to realize when feeding bottle uses, from return-air bottom body 1, thoroughly to avoid the situation generation of child's suction air when sucking, prevent child to rise tripe or spitting milk.This utility model is simple and practical, Be very effective.

As shown in the figure, in the present embodiment, it is as follows that the bag end 2 and body 1 concrete is connected hermetically-sealed construction: wrapping the end 2 adopts silica gel material to make, and body 1 is provided with an annular groove 5 in its sidepiece lower end; The bag end 2, is in tubbiness, its top open part cross-sectional area is less than bottom, can turn up in bag medial wall, the end 2, assemble time first by bag at the bottom of 2 medial walls turn up, then will wrap with bottom body 1 at the end 2 and fit, and then the medial wall at the bag end 2 will be restored, the connection of wrapping the end 2 and body 1 can be realized, the up-small and down-big laminating degree improving the bag end 2 and body 1 in the bag end 2, improves sealing effectiveness.The bottom inside at the bag end 2 is provided with a location sealing post upwardly, location sealing post comprise a bottom 61, in truncated cone-shaped in tubular middle part 62 and one tops 6 in truncated cone-shaped, middle part 62 diameter is minimum; Be provided with an air inlet 3 in location sealing post, this air inlet extends at bag the end 2, and check valve 4 is arranged in air inlet 3; Through hole and location sealing post match.Carry out extruding clamping by the edge of the 61 pairs of through holes in top 6 and bottom of location sealing post, play the bag end 2 and the effect that seals of through hole junction; This sealing structure excellent.

Above-described embodiment is preferred version of the present utility model, and this utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to this utility model spirit, and these equivalent modification or replacement are all included in the scope set by the application's claim.
