Drawings
Fig. 1 is a sectional view of the present invention.
Detailed Description
The invention will be further elucidated with reference to the accompanying drawings:
referring to fig. 1, the leakage-proof structure of the feeding bottle comprises a nipple 1 and a straw cover plate 5, wherein the nipple 1 is made of a soft material, and the straw cover plate 5 is made of a hard material;
the nipple 1 is respectively provided with a spherical suction head 2, a conical squeezing area 3 and a sealing area 4 from top to bottom, a cavity is formed in the nipple 1, the middle of the lower end face of the sealing area 4 is provided with an opening 41 communicated with the cavity, and the spherical suction head 2 is provided with a milk outlet 45 communicated with the cavity;
the shape of the opening 41(a, b, c) is that the upper part 41a is narrow, the lower part 41c is wide, the middle part 41b is a transition between the two, the sealing area 4 is provided with an air-permeable channel 43, the lower part of the air-permeable channel 43 is provided with an air-permeable valve 42, the air-permeable channel 43 is not communicated with the cavity and penetrates through the upper end and the lower end of the sealing area 4, and the air-permeable valve 42 and the lower part 41c of the opening 41 are positioned at the same level;
the upper opening portion 41a of the sealing region 4 is narrower than the lower portion 41c, and is used for tightly adhering to the side wall 54 of the boss 51 of the straw cover 5, so that the sealing between the nipple 1 and the straw cover 5 is ensured, and the air leakage between the nipple 1 and the straw cover 5 due to the failure of sealing is avoided.
The middle part of the suction pipe cover plate 5 is provided with a boss 51 matched with the shape of the upper part 41a of the opening, a plug 52 for connecting a suction pipe is arranged in the boss 51, the suction pipe cover plate 5 is also provided with a vent hole 53, and air can enter the feeding bottle through the vent valve 42 and the vent hole 53 to balance the air pressure inside and outside the feeding bottle.
When the nipple is installed and used, the opening upper part 41a of the nipple 1 is tightly attached to the boss side wall 54 of the straw cover plate to form sealing, and the size and the interference fit between the opening upper part 41a and the boss 51 can be selected to achieve good sealing effect; the lower opening part 41c is not in contact with the side wall 54 of the boss 51, and the vent valve 42 is at the same level as the lower opening part 41c, so that a buffer space is reserved, and the boss 51 is prevented from being in contact with and pressing against the lower opening part 41c, so that the vent valve 42 is abnormally opened to cause liquid leakage.
