The utility model provides air intake of bottles and cans, which is suitable for drinking liquids which are positioned in sealing bottles or cans. The utility model is composed of a base, a press cover, and elastic strips, wherein, the tubular-shaped base which is provided with holes is fixedly connected with the bottles or the cans; the cross section of the press cover is in the shape of T; the middle of the cross section of the press cover is provided with a through hole; the through hole which is positioned at the end with a small diameter of a T-shaped press cover is covered by the elastic strips which are sheathed in the tubular-shaped base following the press cover. While children suck milk, airs with normal pressure outside the bottles push away the elastic strips and enter the bottles when the pressure is negative in the bottles; when the pressure in the bottles is same with the pressure out of the bottles, the elastic strips can automatically retract under the action of elasticity, the hole of the press cover is tightly covered, and the children can continuously suck without changing the airs.

Description

Air intake of bottle and can

A kind of Bottle ﹠ Can admission piece is applied to daily life, belongs to the human lives and needs class.

In daily life, we usually see children when having milk with feeding bottle or drinking water, because in milk or the water inspiration mouth, negative pressure state occurs in the bottle, and the ventilation of having to allows and could continue to suck in the air admission bottle.Can cause like this increases child sucks number of times, mouth fatiguability.

The utility model purpose just provides a kind of when children suck or absorb water, can be from the Bottle ﹠ Can admission piece of trend feeding bottle air inlet.

The utility model is following realization: the Bottle ﹠ Can admission piece is made up of base, gland, elastic strip; Wherein: on the tubular base porose be fixed in bottle or jar on, the gland section is T word shape, has in the middle of it through hole, elastic strip to cover on the through hole of T word shape gland diameter small end and with gland and is enclosed within the tube-like base.In use, after child sucks water or the milk, negative pressure can appear in bottle or the jar, the air pressure of bottle outside will be higher than pressure of the inside of a bottle, so the air of relatively high pressure will be oppressed elastic strip and be made its distortion, the space occur between the through hole on elastic strip and the gland, in the air admission bottle of relatively high pressure, make to keep normal pressure in the bottle, children need not take a breath and can continue to have sucked.This feeding bottle or the jar that has the Bottle ﹠ Can admission piece, because children need not take a breath and can continue to suck, can alleviate the tired of children's mouth and omit time of exchanging gas, and can steadily, happy ensure out the milk amount, the infant easily holds milk hypopharynx amount and time, few for a long time disadvantage of easily choking when going out the milk amount when having prevented from not take a breath valve.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model:

Wherein: 1. nipple; 2. feeding bottle; 3. base; 4. elastic strip; 5. gland;

Fig. 2 is a gland front view in the utility model:

Fig. 3 is a base front view in the utility model:

As shown in Figure 1, base is fixed on the bottle, and bottle can be straight up and down, for attractive in appearance, also can be the middle concavity that is.T word shape gland diameter small end external diameter and base internal diameter are transition fit, promptly just in time compress into base and can not deviate from automatically, and elastic strip covers on the gland center through hole.When gland was compressed into base, elastic strip was tightened and also is pressed into base thereupon.Like this, when be negative pressure in the bottle, the air of the normal pressure that bottle is outer just backs down elastic strip and enters in the bottle, in the bottle, when the bottle external pressure is the same, elastic strip since elastomeric effect bounce back automatically, the gland port lid is tight, so dust can not enter in the bottle.The utility model is not only applicable to bottle, is applicable to that institute is Packed jar yet, as beverage can etc.

Claims (1)

1, a kind of Bottle ﹠ Can admission piece, it is characterized in that: the Bottle ﹠ Can admission piece is made up of base, gland, elastic strip; Wherein: on the tubular base porose be fixed in bottle or jar on, the gland section is T word shape, has in the middle of it through hole, elastic strip to cover on the through hole of T word shape gland diameter small end and with gland and is enclosed within the tube-like base.
