Numeral 0 is made of silicone rubber, and has a hollow portion A in which milk or the like flows from a baby bottle or the like. And this silicone rubber part is the nipple torso 11
And the nipple 12 and the like. This nipple torso 1
Reference numeral 1 denotes a base unit 1 to be attached to the baby bottle or the like.
1a and a nipple torso main body 11b corresponding to a part of the mother's breast
And The nipple 12 is provided with an opening 12a through which milk or the like spouts. Such an artificial nipple 10 is attached to a baby bottle or the like (not shown), and milk or the like contained in the baby bottle is to be drunk through the artificial nipple 10. FIG. 15 shows that the infant 20
It is a figure which shows the state which drinks the milk etc. in a baby bottle (not shown) using 0. As shown, the infant 20
Will press the nipple 12 of the artificial nipple 10 against the baby cavity 22 in the hard palate 21 by the peristaltic movement of the tongue 23 of the self. At this time, these soft palate 2
4. Closed space B formed by tongue 23 and nipple 12
Has a higher pressure than the space C near the epiglottis 26.

Accordingly, when the tongue 23 in FIG. 15 performs peristaltic motion and the contact between the tongue 23 and the soft palate 24 is released, the pressure between the space B where the pressure is high and the other space C is reduced. Due to the difference, the milk and the like in the artificial nipple 10 squirt from the opening 12a of the nipple 12 and are guided toward the epiglottis 26. By generating the pressure in the oral cavity in this way, the infant 20 drinks milk or the like in the baby bottle connected to the artificial nipple 10.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS. still,
Since the embodiments described below are preferred specific examples of the present invention, various technically preferred limitations are added.
The scope of the present invention is not limited to these embodiments unless otherwise specified in the following description.

FIG. 1 is a 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 is provided so as to be continuous with a substantially bowl-shaped nipple trunk 110 corresponding to the mother's breast.
And a nipple 120 corresponding to the mother's nipple. Further, on the left side of the nipple body 110 in the figure, a base 112 which is a flange for connecting to, for example, 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. An opening 121 is provided at the tip of the nipple 120. This opening 121 is
It communicates with a space D provided inside the artificial nipple 100. The hatched wall surface of the artificial nipple 100 that forms the space D is made of, for example, silicon 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 passes through the mouth of the baby bottle and the artificial nipple 100 To the space D. Then, the milk guided to the space D of the artificial nipple 100 is provided in the nipple 120 and the opening 12
1, the nipple 100 is discharged to the outside.

At this time, if the artificial nipple 100 is inserted into, for example, the mouth of a baby, the discharged milk can be given to the baby. Is used when giving artificial milk to a baby or the like using a baby bottle or the like instead of the mother's breast milk, and thus has a shape similar to the mother's breast and nipple as shown in FIG. By the way, as shown in FIG. 1, the nipple 120 of the artificial nipple 100 according to the present embodiment is formed with, for example, three thin and thin portions 122, 122, which are elongated portions, in an annular shape. . And between these thin portions 122, 122, 122, these thin portions 12
Compared to 2, 122, 122, thick portions 123, which are rigid portions having a relatively large thickness, are formed adjacently and alternately.
Specifically, for example, the dimensions are as shown in FIG. As shown in FIG. 3, the thickness of the artificial nipple 100 is, for example, 2.56 mm, and in this case, the thin portions 122 and 12 are thin.
2, 122 is 1.00 m compared to the thickness of 2.56 mm
m. The distance from the opening 121 of the nipple 120 to the end of the first thin portion 122 is 7.46 m.
m, the distance from the thin portion 122 to the end where the thick portion 123 is changed is 9.46 mm, the distance from the thin portion 122 to the end is 11.46 mm, and the end from the thin portion 122 to the thick portion 123 is 16 mm. .46 mm. Thus, the thin portions 122, 122, 122 have a width of 2.00.
mm, three thick portions 123, 123 having a width of 2.00 mm are arranged between the three thin portions 122, 122, 122. These thick portions 123, 123 have thicknesses of other artificial nipples 100.
It is formed to be about 1.00 mm thicker than 56 mm (see FIG. 3).

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 the mother or the like inserts the artificial nipple 100 into the mouth of the infant 200 and the infant 200 holds the artificial nipple 100. In FIG. 2, the feeding bottle and the like are omitted, and only the artificial nipple 100 is shown. Artificial nipple 100
When the nipple 120 of the artificial nipple 100 is attached to the infant 200, the distal end of the nipple 120 is brought into contact with the distal end of the baby cavity 220 of the infant 200, and the artificial nipple 100 is pressed upward by the tongue 230 of the infant 200 in the figure. Become. That is, in the figure of the artificial nipple 100,
The infant 200 is pressed against the portion from the baby cavity 220 to the hard palate 210 and the alveolar ridge 280 to the lip 270.

Incidentally, the infant 200 is placed on the artificial nipple 10.
When milk or the like is to be drunk through the 0, a feeding movement is performed by the peristaltic movement of the tongue as shown in FIGS. FIGS. 4 and 5 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. FIG. 4 (a)
In the infant 200 performing the feeding exercise, the baby 2
There are 20 depressions. The nursing cavity 220 has only a period during which the infant 200 performs a nursing exercise for nursing, and then disappears when it grows up. The mother's nipple enters this baby 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 the side surface of the tongue 230 rises further, so that the tongue 230 comes into close contact with the nipple. And
As shown in FIGS. 4B and 4C, the front of the tongue 230 rises and pushes the nipple from the tongue, and this movement gradually moves to the rear of the tongue 230 as shown in FIGS. 5A to 5C. It will move like a wave. In this process, the tongue 230
Performs peristalsis in a wave-like manner from front to back,
The nipple is squeezed from the root to the tip, and a closed space E is formed between the nipple, the tongue 230, and the upper jaw. The closed space E shown in FIG. 5B becomes smaller as the nipple or the like grows, and preferably, the nipple or the like grows until the closed space E disappears. As a result, the pressure in the closed space E is further increased, and the tongue 2
When this closed space E is opened by the peristaltic motion of 30,
Negative pressure occurs, and the breast milk vigorously flows through the epiglottis 2 of the infant 200.
The baby is spouted in the direction of 60 (see FIG. 2), and by sucking out the spouted breast milk, the feeding operation is completed.

As described above, the infant 200 performs the peristaltic movement of the tongue 230, extends the nipple of the mother, increases the pressure in the closed space E, and effectively generates a negative pressure when the closed space E is opened thereafter. Like that. 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. 2, the nipple 120 is provided with three thin portions 122, 122, 122 (shaded portions).
Due to the peristaltic motion of the tongue 230, the three thin portions 122, 122, 122 extend, and the entire nipple 120 also extends in the mouth of the infant 200. FIG. 7 shows this state. As shown in FIG.
The closed space E formed by the artificial nipple 100, the tongue 230, the soft palate 240, and the like becomes smaller as compared with FIG. As a result, the closed space E having a higher pressure (preferably, a state in which the closed space E disappears) is opened by the peristaltic motion of the tongue 230 as shown in FIG. At this time, a negative pressure is generated, and the milk in the artificial nipple 100 spouts in the direction of the arrow in FIG. The higher the pressure in the closed space E shown in FIG. 7, the larger the amount of the squirted milk. Accordingly, as the nipple 120 extends as in the present embodiment, a higher pressure is applied to the closed space E. And its opening allows
A larger amount of milk can be spouted from the artificial nipple 100.

According to this embodiment, as shown in FIG. 1, the thin portions 122, 122, 12
2, relatively thick portions 123, 123 are provided, and the thin portions 122, 122, 122 and the thick portions 123, 123 are alternately arranged.
The thick portions 123, 123 are, as described above, the artificial nipple 1
Compared to the thickness of 2.56 mm of 00, it is formed to be about 1.00 mm thicker, so that the baby 200 can feed
Even when the artificial nipple 100 is pressed in the oral cavity, the thick portions 123, 123 having high rigidity make the thin portions 122 having low rigidity,
The rigidity of 122 and 122 can be supplemented. FIG. 8 shows this state. FIG. 8 shows an artificial nipple 100 taken from the direction indicated by the arrow in FIG.
Are shown in (b) and (c). FIG. 8 (b)
The artificial nipple 10 in the state of peristaltic movement of the tongue 230 shown in FIG.
This represents a crushed state of 0. As shown in FIG. 8B, the artificial nipple 100 retains its shape without being crushed at all, particularly at a portion hidden by the alveolar ridge 280, despite being pressed by the tongue 230. FIG. 8C shows the collapsed state of the artificial nipple 100 when the peristaltic motion of the tongue 230 shown in FIG. 7 is released. As shown, it can be seen that the artificial nipple 100 is wrapped by the tongue 230 without being crushed.

Therefore, the artificial nipple 10 of the present embodiment is
0 extends in the same manner as the mother's nipple, thereby increasing the amount of milk squirted, and also maintaining the rigidity of the artificial nipple 100 itself without being crushed as in the case of the mother's nipple. 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. Further, in the present embodiment, the thin portion 12
Although 2, 122 and 122 are provided at three places, the present invention is not limited to this, and the thin part 122 may be provided at one place of the artificial nipple 100. Further, this thin portion 122 is attached to the artificial nipple 100 by 2
Obviously, four or more than four locations may be provided.

FIG. 9 is a schematic sectional view showing an artificial nipple 300 according to the second embodiment of the present invention. The configuration of the artificial nipple 300 according to the present embodiment is substantially the same as that of the above-described artificial nipple 100 according to the first embodiment. Equal,
Description is omitted. In FIG. 9, the artificial nipple 300 has a nipple trunk 110, a nipple 120, and a flange 112, as in the first embodiment. However, in the first embodiment, the thin portion 122, which is an extension,
In contrast to the nipple 120, which is provided only on the nipple 120, in the present embodiment, as shown in FIG.
Is also provided. In the present embodiment,
As in the first embodiment, a thick portion 323 that is a rigid portion is provided adjacent to the thin portion 322. However, in the present embodiment, unlike the first embodiment, the boundary between the thin portion 322 and the thick portion 323 is formed smoothly. That is, a waveform is formed as shown in FIG.

As described above, the thin portion 322 and the thick portion 323
By forming the waveform smoothly at the boundary portion of, the decrease in the rigidity of the elongated thin portion 322 can be made gentle. Then, when the infant 200 starts the feeding motion as described above while holding the artificial nipple 300, even if the artificial nipple 300 is pressed in the lateral direction in FIG. Since the artificial nipple 300 is not crushed, the feeding movement of the infant 200 does not become difficult. Also, in the present embodiment, unlike the first embodiment, the thin portion 322
Is provided from the nipple 120 to the nipple torso 110, so that when the infant 200 feeds, the artificial nipple 30
0 will extend more evenly. Further, in comparison with the nipple 120 of the first embodiment, in the present embodiment, even when the nipple 120 is slightly crushed, it is possible to prevent the flow path of milk or the like from being blocked. it can. Thereby, the infant 200 can drink milk more smoothly and more appropriately. Further, in the present embodiment, as shown in FIG. 9, since the boundary between the thin portion 322 and the thick portion 323 forms a gentle waveform, the artificial nipple 300 made of silicon rubber is formed. In manufacturing, it is easy to remove from the mold and to manufacture.

FIG. 10 is a schematic sectional view showing an artificial nipple 400 according to the third embodiment of the present invention. The configuration of the artificial nipple 400 according to the present embodiment is substantially the same as the above-described artificial nipple 100 according to the first embodiment. Therefore, the following description will focus on the differences, and the same configurations will be denoted by the reference numerals. Thus, the description is omitted. In FIG. 10, an artificial nipple 400
As in the first embodiment, the nipple body 11
0, a nipple 120 and a flange 112. However, in the present embodiment, the nipple 120 and the nipple torso 110 are formed to be thinner than the nipple 120 and the nipple torso 110 of the first embodiment. A thin portion 422 which is an extended portion is formed from 120 to the nipple trunk 110. Then, as shown in FIG. 10, a plurality of rigid portions 433 are arranged inside a material forming the thin portion 422. That is, the rigid portion 423 annularly arranged in FIG. 10 is formed of an elastomer, and the thin portion 422 arranged so as to cover the rigid portion 423 is similar to the first embodiment, It is formed of silicon rubber. This elastomer is higher in hardness and harder than silicone rubber, so that when the infant 200 performs a feeding exercise, the artificial nipple 400
The thin portion 422 formed of silicone rubber extends from the rigid portion 423 formed of elastomer.

In this case, since a plurality of elastomers as the rigid portions 433 are provided inside the thin portion 422, the artificial nipple 400
However, in FIG. 10, it becomes difficult to collapse in the vertical direction. Therefore, the artificial nipple 400 is crushed and the infant 200
There is no possibility that the breastfeeding exercise of the baby becomes difficult. Further, in the present embodiment, since rigid portion 423 is provided from nipple 120 to nipple torso 110, infant 20
At the time of the nursing movement of 0, rigidity is ensured also at the nipple trunk 110 of the artificial nipple 400. Further, the rigid portion 423 may be made of not only an elastomer but also a hard silicone. In this case, the thin portion 422 needs to be made of a soft silicone, for example. By making the hardness of silicon different as described above, the thin portion 422 and the rigid portion 423 can be formed. Further, in the present embodiment, for example, three rigid portions 423 are provided, but the present invention is not limited thereto, and a configuration in which only one rigid portion 423 is provided may be adopted.

FIG. 11 is a schematic sectional view showing an artificial nipple 500 according to the fourth embodiment of the present invention. The configuration of the artificial nipple 500 according to the present embodiment is substantially the same as the above-described artificial nipple 100 according to the first embodiment. Therefore, the following description will focus on the differences, and the same configurations will be denoted by the same reference numerals. Thus, the description is omitted. In FIG. 11, an artificial nipple 500
As in the first embodiment, the nipple body 11
0, a nipple 120 and a flange 112. However, in the present embodiment, as shown in FIG.
The first embodiment differs from the first embodiment in that a spiral shape is formed around the 0 and the nipple trunk 110. By forming the thin portion 522 in a spiral shape in this manner, the artificial nipple 500 can be more easily extended when the infant 200 is feeding. In addition, during the feeding, even if pressure is applied in the vertical direction of FIG.
Since the thick portion 523, which is a rigid portion, is always disposed at the position corresponding to 2, the artificial nipple 500 is not crushed and the feeding movement of the infant 200 does not become difficult. Further, in the present embodiment, as shown in FIG.
Since 2 is formed in a spiral shape, the artificial nipple 500 made of silicon rubber can be easily pulled out of the mold in manufacturing, and thus can be easily manufactured.

FIG. 12A is a schematic sectional view showing an artificial nipple 600 according to the fifth embodiment of the present invention. The configuration of the artificial nipple 600 according to the present embodiment is substantially the same as the artificial nipple 100 according to the above-described first embodiment.
The following description will focus on the differences, and the same components will be denoted by the same reference numerals and the description thereof will be omitted. In FIG. 12A, the artificial nipple 600 has a nipple trunk 110, a nipple 120, and a flange 112, as in the first embodiment. However, in the present embodiment, as shown in FIG.
The first embodiment is different from the first embodiment in that a plurality of substantially rhombic shapes are formed on the nipple body 110 of the zero. Since the thin portion 622 is provided on the nipple torso 110 of the artificial nipple 600 in this manner, the nipple torso 110 extends from the nipple 120 during the feeding movement of the infant 200, so that it is closer to the mother's breast. The artificial nipple 600 performs the above operation. In addition, when the thin portion 622 is formed in a substantially rhombic shape, the thin portion 622 is more easily extended in the longitudinal direction due to the property of the substantially rhombic shape. That is, in FIG. 12A, the substantially rhombic shape is
Since the horizontal direction (arrow B) is formed longer than the vertical direction (arrow A), when feeding, the horizontal direction (arrow B)
Easy to stretch. Further, when the artificial nipple 600 extends, the thin portion 622 extends in the direction B in FIG. 12 and deforms into a diamond shape crushed in the direction A in FIG. At this time, the thick portion 62, which is a rigid portion, is adjacent to the thin portion 622.
Since 3 is provided, this rhombus is more prevented from being crushed in the A direction. Therefore, since the artificial nipple 600 moves closer to the actual breast, the infant 200
Can perform a baby-feeding movement more smoothly.

Although the present embodiment has been described as having a substantially rhombic shape, FIG.
The same operation and effect can be obtained even when the shape is substantially wavy as shown in FIG.

FIG. 13 is a schematic sectional view showing an artificial nipple 700 according to the sixth embodiment of the present invention. The configuration of the artificial nipple 700 according to the present embodiment is substantially the same as the above-described artificial nipple 100 according to the first embodiment. Therefore, the following description will focus on the differences, and the same configurations will be denoted by the reference numerals. Thus, the description is omitted. In FIG. 13, an artificial nipple 700
As in the first embodiment, the nipple body 11
0, a nipple 120 and a flange 112. However, in the present embodiment, as shown in FIG. 13, a thin portion 722 which is an extended portion is provided at the distal end of papilla 120. In this way, the thin portion 722 is
Is provided at the distal end of the baby, so that the milk can be spouted more appropriately to the infant 200 who performs the feeding exercise. In other words, in the stage shown in FIG. 5B in the above-mentioned feeding motion, that is, when the illustrated closed space E is opened and the milk is spouted from the artificial nipple 700 into the mouth of the infant 200, the artificial nipple 700 Because the tip extends,
Milk will spout more smoothly. In addition, since the artificial nipple 700 according to the present embodiment is formed of a thick portion 723 which is a rigid portion, except for the tip portion of the nipple 120,
The artificial nipple 700 is hardly crushed in the vertical direction in FIG.
