  However, in these conventional nipples and suckers, since a through hole or a suction valve is formed in the flange at the bottom of the nipple in any case, the configuration is complicated, and high technology and labor are required for production. In short, it was expensive.

  In addition, although the valve structure is adopted, an air passage is always formed in the part. Therefore, when milk with a high temperature is accommodated, the internal pressure of the baby bottle becomes high, and the milk passes from the air passage to the outside. There was also a risk of leakage.

  Furthermore, depending on how the cap is tightened, the valve structure provided on the flange may be deformed, which hinders the normal operation of the valve.

  The present invention has been made in view of such a conventional situation, and adopts a ventilation control structure having a completely different structure from the conventional one to solve the problems of eliminating negative pressure during feeding and preventing milk leakage. The purpose is that.

  In order to solve the above-described problems, the present invention provides a baby bottle comprising an elastic nipple, a baby bottle body, and a cap that is attached between the nipple and an opening of the baby bottle body. A flange portion that can be placed on the top surface of the opening of the baby bottle main body and has a diameter slightly larger than the maximum diameter is formed at the lower end portion of the nipple, and a V-shaped groove is formed annularly over the entire upper surface of the flange portion. And a flat open portion that is continuous with the bottom of the V-shaped groove in the outer direction of a part thereof, and a ventilation groove is formed in the lower surface of the flange portion corresponding to the open portion in the diametrical direction. On the other hand, a means for providing a ventilation adjusting structure by providing a ring-shaped ridge rib that can be fitted into the V-shaped groove on the lower surface of the inward flange provided on the cap was adopted.

  According to the ventilation control structure having such a configuration, when the nipple having the above configuration is placed on the top of the opening of the baby bottle body via the cap, the bottom surface of the flange portion of the nipple is in close contact with the top of the opening. The part is sealed. In addition, when the cap is tightened further, the ribs provided on the bottom surface of the inward flange of the cap spring up the outer end of the ventilation groove via the V-shaped groove to form a ventilation path between the inside of the bottle and the outside air can do. As a result, the negative pressure is eliminated.

  And the means of making the top | upper surface of the opening part of the said baby bottle main body into a horizontal plane of predetermined width was employ | adopted.

  Furthermore, the length of the said ventilation groove employ | adopted the means that the outer side edge part is a length located in the middle of the width | variety of the top | upper surface of the opening part of the said baby bottle main body.

  Thereby, the lower surface of the flange part of a nipple and the said top surface closely_contact | adhere reliably, and the opening part of a bottle is reliably sealed over a perimeter.

  In addition, the said opening part and ventilation groove | channel can be provided in 1 thru | or several places in the circumferential direction of a flange part.

  According to the baby bottle ventilation control structure according to the present invention adopting the above configuration, the nipple flange portion can be securely attached to the top surface of the baby bottle main body over the entire circumference only by lightly tightening the cap to which the nipple is attached. Therefore, it is possible to expect an excellent effect that the opening of the bottle is sealed and the inadvertent leakage of milk can be surely prevented.

  In addition, by tightening the cap, the ring-shaped ridge ribs jump up the outer peripheral end of the flange portion provided with the ventilation groove and open the ventilation groove, so that the negative pressure state in the bottle that occurs during breastfeeding Can be resolved. Further, since the opening area of the ventilation groove can be adjusted by adjusting the tightening of the cap, the degree of eliminating the negative pressure can be changed as appropriate. Therefore, it has become possible to breastfeed comfortably at all times.

  In addition, the top surface of the opening of the baby bottle body is a horizontal surface, and the garden has the outer end of the ventilation groove located in the middle of the q, so the nipple flange is only placed on the top surface. The opening can be reliably sealed over the entire circumference.

  In addition, since the shape and number of ventilation grooves can be selected as appropriate, an optimal one can be selected according to the size of the baby bottle.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a baby bottle ventilation control structure according to the present invention will be described with reference to the accompanying drawings.

  1 (A) and 1 (B), 1 is a baby bottle body made of glass or synthetic resin, 2 is a nipple made of an elastic material such as silicone rubber, and 3 is a nipple 2 for the baby bottle body 1. It is a cap made of synthetic resin for fixing to, and a baby bottle is constituted by these members. In addition, this structure is not different from the structure of various conventional baby bottles. Further, the material of each of the above-described constituent members is not particularly limited, and can be appropriately selected as necessary.

  The shape of the baby bottle main body 1 is not particularly limited, and a conventionally known one such as a bottle with a wide-mouth opening is used. However, as will be described later, the top surface 11 of the opening needs to be flat (horizontal plane). This is because the lower surface of the flange portion 24 of the nipple 2 described below is in close contact. The cap 3 includes a screw body 31 that can be screwed to the screw portion 12 on the outer peripheral surface of the upper end opening of the baby bottle body 1, and an inward flange 32 that engages the nipple 2. While engaging with the constricted part 23 of the nipple 2 to be described below, the flange part 24 of the nipple 2 is sandwiched between the lower surface of the inward flange 32 and the horizontal top surface 11 of the bottle body 1, so that the nipple 2 Is fixed (see FIG. 1B). A ring-shaped protruding rib 32a is formed on the lower surface of the inward flange 32, which will be described later.

  Next, the nipple 2 will be described with reference to FIGS. In each figure, 21 is a nipple with a predetermined opening formed in the top of the head, 22 is a torso, 23 is a constricted part, 24 is a flange part, and 25 is a bottom fitting part. It is the same as a conventional nipple. The material is not particularly limited, but is formed of silicon rubber or the like. The notch opening formed in the upper surface of the top of the nipple 21 is not shown, but is formed by, for example, a cross, Y-letter, or one-letter slit, and milk is sucked out from the notch opening. The body portion 22 has a substantially conical shape with a plurality of gentle step portions in the middle, and the lower end thereof is reduced in diameter to form a constricted portion 23. The inward flange 32 of the cap 3 described above is engaged with the constricted portion 23. Following this constricted portion 23, a flange portion 24 that can be placed on the top surface 11 of the opening portion of the baby bottle body 1 is formed outward, and the maximum diameter thereof is the top surface of the opening portion of the baby bottle body 1 11 is the same as or slightly larger than the maximum diameter. And the lower surface fitting part 25 is formed in the lower surface so that it may fit in the opening part of the baby bottle main body 1. FIG. When attached to the baby bottle main body 1 via the cap 3, the entire circumference of the lower surface of the flange portion 24 can be brought into close contact with the top surface 11 of the baby bottle main body 1 to completely seal the opening of the bottle.

  As shown in FIGS. 2 and 3, a V-shaped groove 24 a is formed in an annular shape on the upper surface of the flange portion 24 over the entire circumference. Also, two of them are formed with open portions 24b that are continuous with the bottom of the V-shaped groove and are flat in the outward direction. On the other hand, on the lower surface of the flange portion 24 corresponding to the open portion 24b, a ventilation groove 24c composed of three parallel grooves is recessed in the diametrical direction (in particular, FIGS. 3B and 3E). (See (F).) The length of the ventilation groove 24c is such a length that the outer end portion is located in the middle of the width of the top surface 11 of the baby bottle body 1, and in relation to the V-shaped groove 24a on the upper surface, V It is located outside the bottom of the groove 24a. The details are shown in the enlarged view of FIG.

  Next, with reference to FIG. 5, the operation of the ventilation adjustment structure including the above-described components will be described. FIG. 2A shows a state in which the inward flange 32 of the cap 3 is engaged with the constricted portion 23 of the nipple 2 and is lightly tightened and screwed to the screw portion 12 of the baby bottle body 1. In this state, the projecting rib 32a provided on the lower surface of the inward flange 32 of the cap 3 is fitted into and pressed into the V-shaped groove 24a on the upper surface of the flange portion 24 of the nipple 2, and thereby the flange portion 24 having elasticity. Since the lower surface of the bottle is completely in close contact with the top surface 11 of the baby bottle main body 1, the opening portion of the baby bottle main body 1 is reliably sealed over the entire circumference. Therefore, even if the baby bottle falls down, the milk inside does not leak out.

  Subsequently, when the cap 3 is further tightened, the rib ribs 32a further press the upper surface of the flange portion 24 of the nipple 2 at the portion of the ventilation groove 24c, as shown in FIG. As a result, the outer peripheral end portion of the flange portion 24 jumps up and the close contact with the top surface 11 is released. Thereby, the ventilation groove 24c is opened to the outside and a ventilation path with the outside air is formed. As described above, this jumping is because the flat open portion 24b is formed on the upper surface on the opposite side of the ventilation groove 24c, and the flange portion 24 and the inner surface of the cap 3 do not interfere with each other. By forming an air passage in this way, the negative pressure during feeding is eliminated, and the infant can easily suck and drink milk.

  In this case, since the open area of the air passage formed by the air vent 24c can be adjusted by the degree of tightening of the cap 3, the state of the air passage optimal for a baby to be fed can be secured.

  When the cap 3 is further tightened, the ventilation groove 24c is crushed and the ventilation path is closed again. Therefore, the milk inside does not leak out.

  Thus, by appropriately adjusting the tightening degree of the cap 3, it is possible to adjust the degree of opening of the air passage, so that it is possible to select the elimination of the negative pressure that is optimal for breastfeeding.

  The ventilation groove 24c is not limited to the above embodiment, and various forms can be adopted. That is, as illustrated in FIG. 6, (A) one groove, (B) two grooves, (C) a U-shaped groove, (D) three grooves gradually. Various things, such as what expands, can be adopted. Moreover, the installation location is not limited to one location, and can be provided at 2 locations (E) as in the embodiment, or at 3 locations (F) or more at equal intervals.

  In short, it is only necessary to provide a vent groove 24c having a desired shape on the lower surface of the flange portion 24 of the nipple 2 so that it can be opened and closed by the degree of tightening of the cap 3 to secure the vent path.
