The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are added. However, the scope of the present invention particularly limits the present invention in the following description. The embodiment is not limited to these embodiments unless otherwise stated.

FIG. 1 is a schematic sectional view showing an artificial nipple 100 according to the first embodiment of the present invention. As shown in the figure, the artificial nipple 100 has a substantially bowl-shaped nipple trunk 110 corresponding to the mother's breast, and a nipple 120 corresponding to the mother's nipple, which is provided so as to be continuous therewith. . Also, on the lower side in the figure of the nipple torso 110,
A base 112 having a nipple-side ventilation hole, which is a flange for connecting to a baby bottle main body (not shown), is provided. The nipple trunk main body 111 is formed continuously from the base portion 112 so as to reduce the diameter. In addition, an opening 121 for the nipple is provided at the tip of the nipple 120. The nipple opening 121 communicates with the beverage space D formed by the nipple trunk 110 and the nipple 120 of the artificial nipple 100. A check valve 130 is provided near the base portion 112 of the beverage space D. The check valve 130 has a check valve main body 131 and a valve 132 as shown in FIG.

The check valve body 131 is made of resin or the like, and has a substantially cylindrical shape as a whole. Therefore, a check valve opening 131a is formed below the check valve main body 131. A mounting hole 131b for mounting the valve 132 in a movable state is provided above the check valve main body 131. This mounting hole 131
A valve 132 is attached to b as shown in FIG. The valve 132 is provided with a disc-shaped valve element 132a as shown in FIG. And this valve body 132a

32b is provided with a stopper portion 1 for stopping the valve 132 from coming out of the mounting hole 131b of the check valve main body 131.
32c is provided. Therefore, the valve body 132a of the valve 132 has a length corresponding to the length of the valve body movable handle 132b in FIG.
Will move upward. When the stopper 132c contacts the inside of the check valve main body 131, the movement of the valve 132a stops, and the valve 132 is opened.

On the other hand, in FIG. 2, the valve body 132a of the valve 132 moves downward in the figure, and the valve body 132
FIG. 13 is a diagram showing that the movement stops by contacting the upper surface of the valve 31 and the valve 132 is closed. Thus, the check valve 13
In FIG. 1 and FIG. 2, for example, milk, which is a beverage from the baby bottle main body provided in the downward direction, is guided into the beverage space D, but conversely, the milk in the beverage space D is baby bottle. This prevents the flow to the main body. After the milk is guided into the beverage space D, the check valve 130 is closed by the milk as shown in FIG. In this state, when a baby or the like, who is the user, performs the feeding exercise described below while holding the artificial nipple 100, the nipple trunk 110 and the nipple 120 of the artificial nipple 100 shown in FIG. The artificial nipple 100 is deformed, and the internal pressure increases. At this time, since the check valve 130 is in the closed state, the internal pressure in the artificial nipple 100 is kept constant without pressure being released from the artificial nipple 100 toward the baby bottle. Non-return valve 13 acting like this
FIG. 4 is a view of FIG. 0 as viewed from above in FIG. 1, and FIG. 3 is a view as viewed from below. As shown in FIG. 3, the mounting holes 13 are provided in three directions around the stopper portion 132c of the valve 132.
1b is formed.

The hatched wall surface of the artificial nipple 100 forming the beverage space D is made of, for example, silicone rubber. When the artificial nipple 100 is connected to, for example, a baby bottle containing milk or the like via the base portion 112, as described above, the milk inside the baby bottle is supplied from the bottle opening of the baby bottle to a check valve. After passing through 130, the artificial nipple 100 is guided to the beverage space D. Then, the milk guided to the space D of the artificial nipple 100 is, as described above, when the infant or the like performs the feeding exercise, as described above.
Through the nipple opening 121 of the artificial nipple 100.

At this time, if the artificial nipple 100 is inserted, for example, into the mouth of a baby, the discharged milk has a structure that can be given to the baby. Since such an artificial nipple 100 is used when a mother gives artificial milk to a baby or the like using a baby bottle or the like instead of the mother's own breast milk, as shown in FIG. 1, the artificial nipple was approximated to the mother's breast and nipple. It has a shape. By the way, the nipple 120 and the nipple trunk 110 of the artificial nipple 100 of the present embodiment
As shown in FIG.
122, 122 are formed in a groove shape, for example, at seven locations in an annular shape. The thickness of the thin portion 122 is about 0.5 mm at the thinnest portion. And this thin part 1
Numeral 22 is formed so as to gradually increase in thickness from the thinnest part, and is configured so that the boundary between the thin part 122 and the inner surface 123 of the artificial nipple 100 becomes gentle, and forms a waveform as shown in FIG. ing. The inner surface 12 of the artificial nipple at this time
3 has a thickness of, for example, about 1.6 mm.

The thin portions 122 are arranged at predetermined intervals, for example, at intervals as shown in FIG.
That is, from the base portion 112 to the thinnest portion of the first thin portion 122 is 12.5 mm, from the thin portion 122 to the thinnest portion of the next thin portion 122 is 4 mm, and from the thin portion 122 to the thinnest portion of the next thin portion 122. Is 4 mm, and up to the thinnest portion of the next thin portion 122 is 3.2 mm.
Similarly, thin portions 122 are arranged at intervals of 3 mm, 3 mm, and 3.9 mm.

The artificial nipple 100 according to the present embodiment
Although it is configured as described above, it is used as follows. First, the artificial nipple 100 is attached to, for example, a baby bottle containing milk or the like. By holding the feeding bottle by the mother and inserting the artificial nipple 100 into the mouth of the infant, the infant is given milk. FIG.
FIG. 3 is a view showing a state where a mother or the like inserts an artificial nipple 100 into the mouth of an infant 200, the infant 200 holds the artificial nipple 100, and sucks up milk into the artificial nipple 100. In FIG. 5, the feeding bottle and the like are omitted, and the artificial nipple 100
Only are represented. That is, when the infant 200 holds the artificial nipple 100, the nipple opening 121 of the nipple 120 is first sucked by a pressure change due to several peristaltic movements. At this time, the valve 13 of the check valve 130
2, the milk flows into the artificial nipple 100 from the mounting hole 131b of the check valve body 131 as shown by the arrow in FIG.

In this state, the nipple 12 of the artificial nipple 100
0 is in contact with the tip of the baby cavity 220 of the baby 200 and the tongue 230 of the baby 200 causes the artificial nipple 10
0 will be pushed upward in the figure. That is, in FIG. 5, the upper surface of the artificial nipple 100 extends from the baby cavity 220 of the infant 200 to the upper palate 210 and the alveolar ridge 28.
It will be pressed against the part from 0 to the lip 270. By the way, when the infant 200 drinks milk or the like through the artificial nipple 100, the infant 200 performs the feeding movement by the peristaltic movement of the tongue as shown in FIGS. FIGS. 6 and 7 show continuous images of the state of the oral cavity in which the infant 200 is performing a feeding exercise using an ultrasonic tomography apparatus. In FIG. 6A, the infant 200 performing the feeding exercise has a depression called the feeding hole 220. The nursing cavity 220 holds the baby 20
0 have only the period of nursing for breastfeeding, and then disappear when they grow up.

The mother's nipple enters this nursing cavity 220 in the mouth of the infant 200. In this state, in the oral cavity, the tongue 230 of the infant 200 hits the nipple from below, and further the tongue 2
The side of 30 rises and comes into close contact with the nipple. Then, as shown in FIGS. 6B and 6C,
The front of the tongue 230 rises and pushes the nipple from below, and this movement gradually moves to the back of the tongue 230 as shown in FIGS. 5 (a) to 5 (c).
In this process, the tongue 230 performs a peristaltic motion in a wave-like manner from the front to the back, the nipple is squeezed from the base to the tip, and the nipple is extended and hits the tip of the feeding cavity 220. Then, a closed space E is formed between the nipple, the tongue 230, and the upper jaw. As shown in FIG.
The closed space E becomes smaller due to the extension of the nipple and the like,
Preferably, the nipple or the like will extend until the closed space E disappears. As a result, the pressure in the closed space E becomes zero.
(Zero), and thereafter, due to the peristaltic motion of the tongue 230, only the tongue 230 moves to the back while the closed space E is sealed, so that the volume of the closed space E increases.
The suction power by negative pressure increases. Then, when the closed space E is opened by the increased suction force, breast milk is squirted vigorously in the direction of the epiglottis 260 (see FIG. 5) of the infant 200, and by swallowing the spouted breast milk, the breastfeeding movement is performed. Will end.

As described above, the infant 200 performs the peristaltic movement of the tongue 230, elongates the nipple of the mother, seals the closed space E, reduces the volume, and performs the peristaltic movement while keeping the hermetically closed state. By moving it, a negative pressure is generated effectively. By effectively generating a negative pressure in this way, the ejection of breast milk is further promoted, and it is intended to drink breast milk more effectively. Also in the artificial nipple 100 according to the present embodiment, as shown in FIG.
Since the thin portions 122 are provided at seven places across the nipple body 110 and the nipple body 110, the tongue 230 of the infant 200 described above is provided.
The seven thin portions 122 are elongated by the peristaltic motion of the nipple, and the nipple 120 and the nipple trunk 110 are also elongated in the mouth of the infant 200. At this time, since a plurality of thin portions 122 are provided at predetermined intervals from the nipple 120 to the nipple trunk 110, the nipple 120 and the nipple trunk 110 are more evenly extended. Further, in the present embodiment, since the check valve 130 is provided, after the milk is introduced into the artificial nipple 100 in the state of FIG. 5 described above, the milk is prevented from returning to the baby bottle side. Will be done. In addition, the pressure in the artificial nipple 100 is prevented from being released to the baby bottle side.

In this state, when the infant 200 performs the peristaltic movement of the tongue 230 described above, pressure is applied to the artificial nipple 100 in the direction of collapsing in the lateral direction of FIG. It is held without falling off. Therefore, the artificial nipple 100 does not collapse due to the peristaltic movement of the infant 200. In addition, the pressure thus held in the artificial nipple 100 acts on the weaker part, the extension 122, and this extension 12
2 will work to extend. In this way, the artificial nipple 100 is stretched without being crushed,
As shown in FIG. 8, the closed space E formed by the artificial nipple 100, the tongue 230, the soft palate 240, and the like is smaller than that in FIG. Thereby, the closed space E having a smaller volume (preferably, the closed space E is in a state where it disappears) is closed by the peristaltic motion of the tongue 230 as shown in FIG. Thereafter, by further moving the tongue 230, a negative pressure is generated, and the milk in the artificial nipple 100 is spouted in the direction of the arrow in FIG. And, if the volume of the closed space E in FIG. 8 is small,
growing.

Therefore, as in the present embodiment, the nipple 120 and the nipple trunk 110 are connected to the extension 122 and the check valve 1.
The extension by the function of the internal pressure by 30 allows a higher pressure to be generated in the closed space E, and a greater amount of milk to be ejected from the artificial nipple 100. Thus, the infant 200 can drink milk more smoothly and more appropriately. Further, in the present embodiment, as shown in FIG. 1, since the boundary between the thin portion 122 and the artificial nipple inner surface 123 forms a gentle waveform, the artificial nipple 100 formed of silicon rubber is used. In manufacturing, it is easy to remove from the mold, making it easy to manufacture. Therefore, the artificial nipple 100 of the present embodiment extends in the same manner as the mother's nipple, thereby increasing the amount of milk squirted, and the artificial nipple 100 itself does not collapse as in the case of the mother's nipple, and has a rigidity. Can also be maintained. In the present embodiment, the example in which the artificial nipple 100 is applied to a baby bottle containing milk is shown. However, the artificial nipple 100 according to the present invention is not limited to this. Obviously, it can be applied to drinking in containers other than baby bottles.

In the present embodiment, the artificial nipple 100
Is provided with seven thin portions 122, but is not limited to this.
Obviously, any number of locations can be provided.
