New description: [New technical field] This creation is a kind of pacifier structure, especially a pacifier structure with breathable and leakproof function. [Prior Art] The nipple is made of soft plastic material, which can be deformed by suction to control the amount of liquid to be eaten. In the process of user's use, it is necessary to introduce air outside the bottle at the right time to balance the air and dust in the bottle. The principle is that the liquid in the bottle is smoothly discharged as shown in Fig. 8. At present, the prior art nipples 6〇, 6〇A, 6〇B are provided with valve holes 61, 61A, 6ib, valves on the nipples 60, 60A, 60B. The holes 6i, 6ia, 61B are directly permeable to the outside air, so they are 'easily leaking out' when the user leans or inverts the suction. If the temperature of the liquid in the bottle is high, it may even cause burns. For the user, It is dangerous. In addition, the valve holes 61, 61, and 61B may be excessively locked with a fixed ring-shaped cover body, so that the intake air amount is insufficient, which causes the user to be quite laborious when sucking, which not only affects the smoothness of the user when sucking. Affect their food intake. [New content] There is a shortcoming in the nipples of the prior art that the intake of the nipple is insufficient and the suction is difficult. The purpose of the creation is to provide a pacifier structure with a breathable and leakproof function, so that the user not only sucks smoothly when smoking. 'And the liquid inside the bottle is not easy to splash, greatly improving safety. To achieve the above objectives, the present invention provides a nipple breathable leakproof structure comprising a teat and a cover. The nipple is integrally formed and has a hollow milk-like convex portion, and an extension portion is laterally extended at a bottom end of the 3 M424949 nipple convex portion; at least one venting hole penetrates a top surface and a bottom surface of the extending portion; The top surface of the extending portion extends toward the nipple convex portion to form a ring-shaped film which is located between the vent hole and the bottom end of the convex portion of the nipple. Preferably, the nipple is provided on the periphery of the extending portion. Annular flange. Preferably, the diameter of the venting opening is tapered along the bottom surface to the top surface of the extending portion. The cover body has an annular side edge, and a mask is formed on the top surface of the cover body for the convex portion of the teat nozzle to protrude and protrude outside the top surface of the cover body, and has a first top surface on the cover body a groove, the first groove is a ring-shaped film that can accommodate the nipple. The ring-shaped film is movable against the cover. Preferably, the inner wall of the annular side of the cover has an annular thread. Preferably, the cover body comprises a second recess adjacent to the first recess and corresponding to the annular flange of the nipple. When the present invention is used, the convex part of the nipple is pierced from the lower part of the cover body through the perforation of the cover body, and the cover body is sleeved around the convex part of the nipple, so that the nipple is placed at the top of the nipple and is opposite to the top. The first groove of the cover body and the ring-shaped flange of the nipple correspond to and engage with the second groove of the cover body. The preferred embodiment of the present invention further comprises a bottle which is a bottle for holding a liquid, and the cover provided with the nipple can be fixed by a combination of the side of the morning thread having an annular thread and the bottle. When the user sucks the nipple, the force of sucking causes the ring film of the nipple to deform, and a gap is formed between the ring film and the first groove, and the air of the outside can be between the cover and the nipple, and The gap enters the bottle through the vent hole, so that the negative pressure in the bottle becomes low, the nipple is not easy to be compressed and deformed, and the user can smoothly avoid the inhalation of air and M424949 causes flatulence; when the user uses the bottle upside down, the bottle can be blocked due to the direction of the air flow. The internal liquid leakage leaks to achieve the effect of preventing leakage. [Embodiment] As shown in Fig. 1, the pacifier structure 10 of the present invention includes a nipple 2 〇 and a cover 30. As shown in FIG. 2 and FIG. 3, the nipple 2 is integrally formed into a 35, and the nipple 2 has: a hollow-like convex portion 21' and a laterally extending extension of the bottom end of the convex portion U of the nipple 2A. 22, and an annular flange 23 is formed on the top surface of the extending portion 22 near the circumference toward the end of the convex portion; at least one of the venting holes 24 penetrates the top surface and the bottom surface of the extending portion 22 and the diameter of the vent hole μ The film is tapered along the bottom surface of the extending portion 22 to the top surface; the ring-shaped film is located between the venting hole 24 and the bottom end of the teat 20, and the annular film 25 is convex from the top surface of the extending portion 22 toward the nipple 2 The tip end portion 21 extends obliquely. As shown in FIG. 4, the cover body 3 has an annular side 31, and the inner wall of the annular side has an annular thread, and a mask is formed on the top of the cover body 3 for the milk. The convex portion 21 penetrates through and protrudes from the top surface of the cover body 30 and has a first groove 32 and a second groove 33 on the inner surface of the cover body 3, and the first groove 32 can pass through Pay very much. λ is a ring-shaped film 25 of the valley nipple 20, the end of the ring-shaped film 25: the movable abutting against the inner top surface of the cover body 3; the second groove 33 is adjacent to the first concave; j * 3 ?, 廿 丨 1 slot 32 and corresponds to the annular flange 23 of the nipple 2 。. When in use, please refer to FIG. 1 , which is to pierce the underside of the convex portion 21 / cover 3 of the nipple 20 through the cover 3 , and the cover 30 is sleeved on the nipple 20 Around the gossip 21, the ring-shaped film 25 of the teat 20 is accommodated in the first groove 32 of the body 3 and abuts against the cover 30, and the nipple 20 is 3L convex '. 彖 22 series and the cover The second groove η of the 3 相对 corresponds and engages, and the ring-shaped film 23 of the 5 M424949 nipple 20 can be accommodated and abuts against the four grooves 32 of the cover 3 。. Referring to FIG. 5 and FIG. 7 , when the present invention is used, the cover 3 with the nipple 2 can be covered in the opening of a bottle, and the annular side 31 having an annular thread is used. It is fixed with the bottle 4, which is used to rectify the bottle which can hold the liquid. When the user sucks the nipple 2 ,, the force of the sucking force causes the ring-shaped film 25 of the nipple 20 to deform, and a gap 50 is formed between the ring-shaped film 25 and the first groove 32, and the air of the outside can be slid along the cover. The body 30^ is between the nipples 2, and enters the bottle 40 through the vent hole 24 through the slit 50, so that the user can smoothly avoid the inhalation of the air and cause the flatulence, and achieve the effect of ventilation, and on the other hand, the bottle 40 The negative pressure becomes lower, the nipple 2 is not easy to be compressed and deformed, and the shape can be restored. In order to facilitate the user to repeatedly absorb the suction... When the person inverts the field 4G, as shown in Fig. 1, the airflow direction enters the bottle 40 from the outside. Therefore, the liquid in the bottle 4 is not easily leaked, and the effect of the third is 30. The ring (10) 25 abuts against the cover groove 32 in the unabsorbed state, and blocks the vent hole 24 from leaking.幻幻儿全 [Simplified illustration of the drawings] Figure I is a partial cross-sectional view of an embodiment of the present creation.
