[Technical field of invention]

The present invention relates to a nipple for a baby bottle. It is possible to encourage the overall development of the oral cavity, jaws, etc. through active exercise. The present invention also relates to a nipple for a baby bottle that sufficiently prevents liquid from running out and dripping at the suction port.

0002

[Technical background of the invention]

In recent years, with advances in childcare science for infants and young children, it has become necessary to There is a growing trend towards promoting the development of children.

0003 Conventionally, when the suction opening of a baby bottle has a round hole, it is possible to feed even if the infant does not make suction movements. Because milk comes out just by tilting the bottle, it is almost impossible to support the development of the infant's oral cavity. There wasn't.

0004 In addition, the nipple outlet is cut into an X-shape and a Y-shape to create a valve mechanism. There are also suction ports available commercially, in which the valve is opened by the infant's suction movements. Although it can encourage the development of the infant's oral cavity because it closes and milk comes out, the sucking movement However, there is almost no occlusal movement, and it is not sufficient to promote jaw development. However, it is insufficient from the perspective of promoting the overall development of the oral cavity, jaws, etc. of infants. Ta.

[0005] On the other hand, conventionally, there have been problems with dripping of liquid such as milk from the suction port and difficulty in draining the liquid. It had become. For example, in the case of a round-hole suction port, milk can be dispensed simply by tilting the bottle. In the case of the X-cut and Y-cut suction ports mentioned above, the valve mechanism and Because it acts as a liquid, it can almost prevent dripping, but it is sufficient to prevent liquid from running out. I couldn't say yes. In particular, if highly viscous fruit juice etc. is placed in a baby bottle, Even with X-cut and Y-cut, liquid may drip, which has been a problem. So Therefore, the appearance of a nipple that can sufficiently prevent fluid shortage and dripping has been long awaited. there was.

[0006]

[Purpose of invention]

The present invention was developed in view of the above-mentioned circumstances, and is designed to help infants suck during breastfeeding. Encourage active pulling and occlusal movements to fully promote the overall development of the oral cavity, jaws, etc. For baby bottles that can be used to prevent fluid from running out or dripping at the suction port. The purpose is to provide nipples.

[0007]

[Summary of the idea]

In order to achieve this purpose, in this invention, In a baby bottle nipple with a suction port on the tip, The tip surface with this suction port is formed into a concave surface that is recessed inside the nipple. It is characterized by.

[0008] In this way, since the tip surface with the suction port is formed into a concave surface, the concave tip The end face acts as a valve to open and close the suction port, and also prevents the suction port from opening. This poses great resistance. Therefore, the suction force due to the infant's suction movement is applied to the tip surface. At the same time, only when the infant bites the nipple, the suction port opens and milk etc. coming out. Therefore, when breastfeeding, encourage infants to actively perform sucking and biting movements. This can fully promote the growth of the oral cavity, jaws, and other areas.

[0009] Furthermore, if the tip surface with the suction port is formed into a concave surface, the tip surface will return to its original shape. Because the force of trying to return to its shape is large, the suction port returns to its original position as soon as the infant stops breastfeeding. Because it returns to its shape and closes, it drains very well. Also, the suction port tries to open. Since it has a high resistance to water leakage, it can sufficiently prevent dripping and is hygienic. . In particular, even if highly viscous fruit juice is placed in a baby bottle, the liquid may run out. And dripping can be sufficiently prevented.

[Specific explanation of the idea] Hereinafter, a nipple for a baby bottle according to an embodiment of the present invention will be explained in detail with reference to the drawings. Ru.

[0011] FIG. 1 is a longitudinal sectional view of a nipple for a baby bottle according to an embodiment of the present invention, and FIG. A plan view of the neck, FIG. 3 is an enlarged view of the main part of FIG. 1, and FIG. 4 explains the action of the nipple shown in FIG. 3. This is a diagram for

0012 The nipple 1 for a baby bottle according to this embodiment includes a base 3 having a flange 2 at the lower end, and a base 3 having a flange 2 at the lower end. A substantially hemispherical shell-shaped body 5 continues above 3, and a part of this body 5 extends further upward. It has a distal end portion 7 extending outward. Furthermore, is this nipple tip 7 made of flexible material? It is formed from

[0013] The lower end of the trunk 5 of the nipple 1 has an outwardly projecting trunk flange 5a. An annular groove 9 is formed on the outer periphery of the upper part of the base 3 which is continuous with the body flange 5a. It is formed. The nipple 1 is a cap member having an opening through which the nipple 1 is inserted. (not shown) to the baby bottle body (not shown), but at this time, the flange of the base 3 The flange 2 is held between the cap member and the upper end of the baby bottle body, and the annular groove 9 is engaged with the opening in the member.

[0014] The flange 2 also includes a through hole 11 and a hemispherical shell-shaped valve body that covers the lower part of the through hole 11. 13 are formed. This valve body 13 has a notch extending in the radial direction of the flange 2. An eye 13a is provided to allow air to flow in from the outside of the baby bottle, and to allow air to flow in from the inside. It is a check valve that prevents milk from flowing out.

[0015] Now, in this embodiment, as clearly shown in FIG. 22 is formed into a concave surface so as to be recessed inside the nipple. This concave surface is preferably , as shown in the figure, is preferably formed from a curved surface with a constant curvature. Sara In the illustrated example, the suction port 21 has a - shape, but other types include an X cut and a Y cut. A flat hole is preferable, and a round hole is also acceptable.

[0016] In this way, since the tip surface 22 is formed into a concave surface, the tip surface 22 has a suction port. It acts as a valve to open and close 21, and also prevents the suction port 21 from opening. It imposes great resistance. Therefore, as shown in FIG. The suction force caused by the sucking movement of the infant acts on the suction port 21, and at the same time, the infant moves toward the arrow 2. Only when the nipple tip 7 is bitten from the direction 4, as shown by the solid line in FIG. The neck tip 7 is distorted, the suction port 21 opens, and milk etc. come out. Therefore, infants Babies are forced to perform sucking and occlusal movements while breastfeeding; Encourages active movement and promotes the overall development of the oral cavity, jaw, etc. I can do it.

[0017] Furthermore, if the distal end surface 22 is formed into a concave surface, the distal end surface 22 may return to its original shape. Due to the large force exerted by the infant, the suction port 21 returns to its original shape as soon as the infant stops breastfeeding. The liquid drains very well because it returns to the original position and closes.

[0018] Furthermore, since the suction port 21 has a large resistance to opening, there is sufficient liquid dripping. can be prevented and is hygienic. In particular, avoid putting highly viscous fruit juices into baby bottles. Can sufficiently prevent liquid shortage and dripping even when the liquid is .

[0019] Note that the present invention is of course not limited to the embodiments described above, and can be modified in various ways. It is Noh. In particular, the concave surface of the distal end surface 22 only needs to be recessed inside the nipple; It is not limited to this, and may have various shapes. As mentioned above, the suction port 21 also has a negative shape. However, various other shapes such as an X cut, a Y cut, and a round hole may also be used.

[0020]

[Effect of the idea]

As mentioned above, in the present invention, the tip surface where the suction port is provided is formed into a concave surface. Because of this, there is a lot of resistance to the suction port opening, and the infant makes suction movements. Only when the nipple is bitten at the same time, the suction port opens and milk etc. comes out. therefore , allows infants to actively perform sucking and occlusal movements during breastfeeding, and improves the oral cavity, It can sufficiently promote the growth of the jaw and other areas.

[0021] Furthermore, because the force of the tip surface trying to return to its original shape is large, the infant may stop breastfeeding. At the same time, the suction port returns to its original shape and closes, so the liquid drains very easily. Also , since there is a large resistance to the suction port opening, it is difficult to sufficiently prevent liquid dripping. can be used and is hygienic. In particular, highly viscous fruit juices are placed in baby bottles. Even in such cases, running out of liquid and dripping can be sufficiently prevented.
