Technical field

This utility model relates to a kind of bottle end intake structure of feeding bottle, is meant a kind of bottom structure-improved that is applicable to the hard feeding bottle especially.

Background technology

The structure of existing various feeding bottles, the most widely used is the hard feeding bottle, be provided with a bottom in the bottom surface of feeding bottle, be provided with the cushion of a sealing in the bottom, in cushion, offer a cross bore or a word hole, as the structure of air inlet, this structure, through secular use, discovery is easy to split leakage, has lost the function of sealing of cushion, needs to change new product, cause the inconvenience of user, and, can further have influence on the whole speed of using because of the flow of air inlet, through research because of hole is little if be used for bigger child, discovery is the problems of liquid flow deficiency because of air, the suction that can allow hungry child exert oneself very much, the effect of sucking-off milk increases fast, though this kenel has ensured that the baby's is safe in utilization, but relatively allow some childs inhale less than, thereby produce the problem that some use; This shows that the shortcoming that this existing structure exists has influence on the convenience of use, for the article of more realistic demand are provided, the inventor researches and develops, and uses the problem that easily produces that goes up to solve prior art.

The utility model content

For overcoming above-mentioned defective, this utility model main purpose is to provide a kind of bottle end intake structure of feeding bottle, at the bottom of bottle, form fast any flow intake method of valve-type, with big flow with open the air inlet that entire diaphragm type valve block replaces existing small through hole pattern fast, make it can be applicable to that the bigger neonatal of bigger infant and suction uses, can allow the action of air inlet more smooth and easy, particularly the edge part of valve block can be held entire along the suction action that sucks.

For achieving the above object, the bottle end intake structure of this utility model feeding bottle, it has a bottom that is arranged in a feeding bottle lower end, bottom contains a base plate and the ring limit portion that one links to each other, ring limit portion is for being formed by the base plate bending, inner surface in ring limit portion is provided with junction surface in, is engaged in an outer engagement portion of feeding bottle with interior junction surface; Be provided with an outstanding engaging post as the conical head rivet shape in the centre of base plate, the first half of engaging post is an enlarged head, and Lower Half is a shaft portion; In base plate, be provided with at least one perforation; Other is provided with a valve block of being made by flexible material, and valve block is covered within each perforation of base plate, and valve block is provided with a connecting hole, and connecting hole penetrates the shaft portion that is sleeved on the engaging post; The periphery of valve block is equipped with thinner together edge part, makes it air-breathing when mobile, can start slightly towards base plate; Allow air suck in the feeding bottle with perforation.

The bottle end intake structure of this utility model feeding bottle, use elastic valve block that the perforation of bottom is launched air-breathing function, no matter the sort of suction, the capital makes valve block interoperation very swimmingly, and action accurately can be adapted to various flow requirements, particularly big flow requirements, can improve inhale the service property (quality) of milk, so good usability can be provided, be fully unlike the prior art a structure.

The specific embodiment

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

Extremely shown in Figure 6 as Fig. 1, bottle end intake structure for this utility model feeding bottle, has a bottom 2 that is arranged in a feeding bottle 1 lower end, bottom 2 contains a base plate 21 and the ring limit portion 22 that one links to each other, ring limit portion 22 is for being formed by base plate 21 bendings, inner surface in ring limit portion 22 is provided with junction surface 23 (representing with internal thread part among the figure) in, be engaged in an outer engagement portion 11 (representing with external thread part among the figure) of feeding bottle 1 with interior junction surface 23, wherein, interior junction surface 23 and outer engagement portion 11 are meant screw thread; Be provided with an outstanding engaging post 24 as the conical head rivet shape in the centre of base plate 21, the first half of engaging post 24 is an enlarged head 25, and Lower Half is a shaft portion 26; Being provided with number in base plate 21 bored a hole for 27 (representing with three holes among the figure); Other is provided with a valve block 3, is made by flexible material, makes valve block 3 be covered in 27 the interior side of respectively boring a hole of base plate 21, and valve block 3 is provided with a connecting hole 31, allows connecting hole 31 penetrate to be sleeved on the shaft portion 26 of engaging post 24; 27 allow air suck in the feeding bottle 1 to bore a hole.Wherein most particularly be equipped with thinner together edge part 32 in the periphery of valve block 3, its natural state can be toward sagging, can seal and be affixed on base plate 21, make it when the nipple suction is fair, when producing vacuum suction, edge part 32 is started slightly towards base plate 21 places, can allow that an amount of air is entered in the feeding bottle 1 by perforation 27 places.

Structure in sum, this utility model uses elastic valve block that the perforation of bottom is launched air-breathing function, no matter the sort of suction, the capital makes valve block interoperation very swimmingly, and action accurately can be adapted to various flow requirements, particularly big flow requirements, can improve inhale the service property (quality) of milk, thus good usability can be provided, be one fully with existing different structure.

The above is the detailed description of preferred embodiment of the present utility model and graphic; be not to be used for limiting this utility model; protection domain of the present utility model should be as the criterion with claim; the embodiment and the approximate construction of the spirit variation similar with it of all claim all should be contained among this utility model.
