Description

{Nipple and nursing container comprising the same}

The present invention relates to a pacifier and a mammal having an pacifier.

Background Art [0002] Mammals having artificial nipples and artificial nipples mounted on a mammalian body such as a bottle accommodating milk or pre-exploited breast milk beverages are widely used in the feeding of infants and toddlers. When infants and toddlers bite the pacifier and aspirate to feed from the mammal, the pressure in the mammal decreases as the beverage decreases. As the pressure in the mammals decreases, it becomes gradually difficult for infants and toddlers to breastfeed. Thus, an artificial nipple having a non-return valve capable of introducing external air into the mammal, and a mammal having an artificial nipple are known so that the pressure in the mammal is not lowered (Patent Document 1).

Japanese Patent Publication No. 2011-92551

However, since the mammal having the artificial nipple and the artificial nipple described in Patent Document 1 has only a single backflow prevention valve, the flow rate of the air flowing into the mammal according to a decrease in pressure within the mammal, that is, an increase in pressure difference between the inside and outside of the mammal It cannot be adjusted to decrease. Therefore, as the pressure difference between the inside and outside of the mammal increases, the flow rate of air flowing into the mammal increases. Therefore, the amount of beverages that infants and toddlers can feed in one feeding operation increases, but too much of the beverage is not desirable for infants and toddlers. In other words, in the case of infants and toddlers with strong suction power at the time of feeding, the time (feeding time) required to drink all the drinks in the mammal is shortened. On the other hand, in the case of infants and toddlers with weak suction power at the time of feeding, the feeding time becomes longer. Therefore, in the mammal having the artificial nipple and the artificial nipple described in Patent Document 1, the feeding time cannot be appropriately adjusted according to the suction force of the infant, that is, the pressure difference between the inside and outside of the mammal.

An object of the present invention is to provide an infant with a pacifier and a mammal having an pacifier capable of adjusting an appropriate feeding time or flow rate of a drink in a simple manner.

According to an embodiment of the present invention, the artificial pacifier body, the first pressure member having a plurality of vent holes having different opening areas at the same pressure difference, and a second vent member having a vent hole, An artificial nipple mounted on a body of a mammal for receiving a beverage, by selectively communicating the ventilation holes of the second ventilation member with respect to the plurality of ventilation holes of the first ventilation member, thereby allowing the mammal to pass through the communicating ventilation holes. An artificial nipple is provided, which is capable of adjusting the flow rate of gas flowing in from the outside.

That is, in the present embodiment, the flow rate of the gas flowing in from outside the mammal by appropriately selecting and communicating the ventilation holes of the second ventilation member with respect to the plurality of ventilation holes of the first ventilation member according to the suction force at the time of feeding of an infant or toddler. Adjust it. For example, in the case of infants and toddlers with strong suction power during feeding, the ventilation holes of the first ventilation member are selected so that the flow rate of the gas flowing in from outside the mammal is reduced. As a result, the pressure in the mammal that has been lowered by aspiration rarely rises, so that the amount of drink that an infant or toddler can feed in one feeding operation can be reduced. On the other hand, in the case of an infant with a weak suction force during feeding, the ventilation hole of the first ventilation member is selected so that the flow rate of the gas flowing in from outside the mammal increases. As a result, the pressure in the mammal that has been lowered by aspiration immediately rises, so that the amount of drink that an infant or toddler can feed in one feeding operation can be increased. Therefore, it is possible to realize an appropriate feeding time for infants and toddlers or to adjust the flow rate of beverages in a simple manner. On the other hand, the appropriate feeding time in the present specification means, for example, a time required for drinking all the drinks in the mammal is about 15-20 minutes.

In addition, according to another embodiment of the present invention, there is provided an artificial nipple characterized in that the plurality of ventilation holes of the first ventilation member or the ventilation holes of the second ventilation member is a backflow prevention valve.

That is, in the present embodiment, the plurality of vent holes of the first vent member or the vent holes of the second vent member is a backflow prevention valve, thereby preventing the beverage from leaking out of the mammal through the vent holes communicating with each other.

In addition, according to another embodiment of the present invention, the first ventilation member and the second ventilation member are in a donut shape and so that the artificial nipple body is mounted on the mammal body through the first ventilation member and the second ventilation member. An artificial nipple is provided, which is formed in a flat shape and is formed by overlapping the first ventilation member and the second ventilation member with each other so that the ventilation holes communicate with each other.

That is, in the present embodiment, the artificial nipple is attached to the mammal body through the first vent member and the second vent member formed in a donut shape and a flat plate shape, thereby adjusting an appropriate feeding time or a flow rate of beverage for an infant with a simple mechanism. Can be.

Further, according to another embodiment of the present invention, each of the plurality of vent holes in the first vent member is formed in one of the concave or convex part, and the vent hole of the second vent member is different from the concave or convex part. An artificial nipple provided on the side, wherein the communication of the ventilation hole is made by fitting the concave portion and the convex portion of the first ventilation member and the second ventilation member.

That is, in the present embodiment, since the communication of the ventilation holes is achieved by fitting the concave and convex portions of the first ventilation member and the second ventilation member, communication of the ventilation holes can be performed more reliably.

Further, according to another embodiment of the present invention, a mammal provided with the artificial nipple and the mammal body of the above-described embodiment is provided.

According to the present invention, it exhibits a common effect that the proper feeding time or the flow rate of the beverage can be adjusted in an easy manner for infants and toddlers.

Hereinafter, embodiment of this invention is described in detail, referring drawings. Throughout the drawings, common reference numerals are assigned to corresponding elements.

1 is a perspective view of a mammal 1 according to an embodiment of the present invention, and FIG. 2 is a partial longitudinal cross-sectional view including the artificial nipple 2 of the mammal 1 in FIG. 1. On the other hand, in this specification, in description of each component of the mammal 1, it is prescribed as'upper' or'lower' based on the arrangement in the mammal 1 in a horizontally erected state.

The mammal 1 has an artificial nipple 2, an installation member 3, and a mammal body 4. The artificial nipple 2 has a first vent member 5 which is a vent part, a second vent member 6 which is a vent stopper, and an artificial nipple body 7. The mammalian body 4 is a bottle or the like for accommodating a drink for infants and toddlers such as milk or pre-exploited breast milk, and is formed of, for example, glass or hard synthetic resin. The artificial nipple body 7 is installed in the mammal body 4 through the first vent member 5 and the second vent member 6, and as will be described later, the installation member 3 is attached to the mammal body 4 It is fixed by screwing with respect to.

3 is a top view of the installation member 3 of the mammal 1 of FIG. 1, FIG. 4 is a front view of the installation member 3 of FIG. 3, and FIG. 5 is a line AA of the installation member 3 of FIG. It is a cross section of.

The installation member 3 is a cylindrical member, and is formed by integrally molding a hard synthetic resin, for example, polypropylene. The installation member 3 has an installation member body 31 and an annular flange portion 32 extending inward in the radial direction from the top of the installation member body 31. The flange portion 32 defines the upper opening 33. The pacifier 2 protrudes upward through the opening 33. On the lower surface of the flange portion 32, an annular fitting projection 34 (Fig. 5) extending downward is formed. The fitting projection 34 fits into the fitting groove 75a of the pacifier body 7 as will be described later. The lower circumference of the installation member body 31 defines an opening 35 having a larger diameter than the upper opening 33. On the inner circumferential surface of the installation member body 31, a female screw portion 36 that is screwed with a male screw portion 41 (FIG. 2) provided on the outer circumferential surface of the upper end portion of the mammal body 4 is formed.

FIG. 6 is a top view of the first ventilation member 5 of the pacifier 2 of the mammal 1 of FIG. 1, FIG. 7 is a bottom view of the first ventilation member 5 of FIG. 6, and FIG. 8 is 6 is a cross-sectional view along line AA of the first ventilation member 5 of FIG. 6, FIG. 9 is a cross-sectional view along line BB of the first ventilation member 5 of FIG. 6, and FIG. 10 is a first ventilation member of FIG. 7 ( It is a sectional view at line CC of 5).

The first ventilation member 5 is a donut-shaped and flat-shaped member, and is formed by integrally molding an elastic member such as soft synthetic resin, for example, silicone resin. Below the outer circumferential surface of the first ventilation member 5, an annular flange portion 51 extending outward in the radial direction is provided. Further, four circular fitting holes 52a, 52b, 52c, and 52d are formed on the upper surface of the first ventilation member 5. Each of the fitting holes 52a, 52b, 52c, and 52d is arranged at equal intervals around the central axis of the first ventilation member 5. In each of the fitting holes 52a, 52b, 52c, backflow prevention valves 53, 54, 55 are provided, respectively. A backflow prevention valve is not provided in the fitting hole 52d and is closed. Therefore, it can be said that the first ventilation member 5 has three ventilation holes 53, 54, 55 as the backflow prevention valves 53, 54, 55. On the other hand, a closed boss portion 56 is formed on the back side of the first ventilation member 5 corresponding to the fitting hole 52d, and an opening 57 is formed in the center of the first ventilation member 5. have.

Each of the backflow prevention valves 53, 54, and 55 has a pair of valve bodies. For example, the backflow prevention valve 53 has a pair of valve bodies 53a and 53b, as shown in FIGS. 7 and 10. The valve bodies 53a and 35b are plate-shaped movable pieces extending obliquely downward from the inner circumferential surface of the fitting hole 52a. Between the front ends of the respective valve bodies 53a and 53b, slits 53c extending along the radial direction of the first vent member 5 are formed. 8 is a sectional view through the slit 53c, the slit 53c is not shown in FIG. 8, but only one valve body 53a is shown. A partition wall 53d is formed around the valve bodies 53a and 53b on the lower surface of the first ventilation member 5.

Normally, as shown in Fig. 10, the slits 53c are closed so that the valve bodies 53a, 53b have a wedge-shaped cross section. Therefore, the pressure due to the flow of gas or the like directed from the bottom to the top of the first vent member 5 acts in a direction in which the valve bodies 53a and 53b are more closed. That is, the slit 53c remains closed, and the backflow prevention valve 53 is closed with respect to the flow upward from the bottom of the first ventilation member 5. On the other hand, the pressure due to the flow from the top to the bottom of the first vent member 5 acts in a direction in which the tip ends of the valve bodies 53a and 53b are separated from each other. Therefore, the slit 53c is opened, and the backflow prevention valve 53 is opened with respect to the flow downward from the top of the first ventilation member 5.

The other non-return valves 54 and 55 are similar to the non-return valve 53 in terms of basic configuration and operation other than the shape of the valve body. The backflow prevention valve 54 has a pair of valve bodies 54a, 54b. The valve bodies 54a and 54b are movable pieces of a curved shape extending obliquely downward from the inner circumferential surface of the fitting hole 52b. Between the front ends of the valve bodies 54a and 54b, slits 54c extending along the radial direction of the first vent member 5 are formed. Normally, the slit 54c is closed so that the valve bodies 54a, 54b have an arc-shaped cross section. That is, normally, the valve bodies 54a and 54b form one convex curved surface as a whole.

The backflow prevention valve 55 has a pair of valve bodies 55a, 55b. The valve bodies 55a and 55b are movable pieces of a flat plate shape extending from the inner circumferential surface of the fitting hole 52c toward the lateral direction. Between the front ends of the valve bodies 55a and 55b, slits 55c extending along the radial direction of the first vent member 5 are formed. A partition wall 55d is formed around the valve bodies 55a and 55b on the lower surface of the first ventilation member 5. A partition wall 54d is formed around the valve bodies 54a and 54b on the lower surface of the first ventilation member 5. Normally, the slits 55c are closed so that the valve bodies 55a and 55b have a straight cross-section. That is, normally, the valve bodies 55a and 55b form one plane as a whole.

The above-mentioned three non-return valves 53, 54, and 55 have the pressure due to the flow required to open in this order, that is, the pressure due to the flow required to open each slit 53c, 54c, 55c. It grows. This depends on the magnitude of the force component force acting in the direction of separating the tip of each valve body when a pair of valve bodies are subjected to pressure from the upward to downward flow of the first vent member 5. When each of the non-return valves receives the same pressure in the flow direction in which each is opened, that is, is disposed under the same pressure difference, the magnitude of the force force acting on each valve body is the arc of the valve body disposed in the wedge shape. It is larger than the valve body arranged in the shape, and the valve body arranged in the arc shape is larger than the valve body arranged in the linear shape. Therefore, the opening area of each slit 53c, 54c, 55c when arranged under the same pressure difference decreases in this order, and the flow rate of the backflow prevention valves 53, 54, 55 also decreases in this order.

11 is a top view of the second ventilation member 6 of the artificial nipple 2 of the mammal 1 of FIG. 1, FIG. 12 is a front view of the second ventilation member 6 of FIG. 11, and FIG. 11 is a cross-sectional view along the line AA of the second ventilation member 6.

The second ventilation member 6 is a donut-shaped and flat-shaped member, and is formed by integrally molding a hard synthetic resin, for example, polypropylene. In the vicinity of the opening 61 of the upper surface of the second ventilation member 6, an annular support wall 62 extending upward is formed. In addition, an annular circumferential wall 63 extending downwardly from the outer circumferential circumference is formed on the lower surface of the second ventilation member 6. Therefore, a concave portion 64 partitioned by the circumferential wall 63 is formed on the lower surface of the second ventilation member 6. The first vent member 5 is fitted to the recess 64 as will be described later.

A hollow boss portion 65 extending downward is formed on a portion of the lower surface portion corresponding to the upper surface portion of the second ventilation member 6 on which the supporting wall 62 is formed. On the upper surface of the second ventilation member 6, a sectional semicircular groove 66 extending from the outer circumferential surface of the second ventilation member 6 toward the inside in the radial direction is formed. The sectional semicircular groove 66 communicates with the hollow boss portion 65 and forms a vent hole 67.

14 is a top view of the pacifier body 7 of the pacifier 2 of the mammal 1 of FIG. 1, FIG. 15 is a front view of the pacifier body 7 of FIG. 14, and FIG. Fig. 17 is a right side view of the pacifier body 7, and Fig. 17 is a sectional view along line AA of the pacifier body 7 in Fig. 14, and Fig. 18 is a sectional view along line BB of the pacifier body 7 in Fig. 16. .

The pacifier body 7 is a hollow member, and is formed by integrally molding an elastic member such as a soft synthetic resin, for example, silicone resin. The pacifier main body 7 has a base portion 71, a first nipple body portion 72, a second nipple body portion 73, and a nipple portion 74. The base 71 has a flange portion 75, a neck portion 76, and an overhang portion 77.

The flange portion 75 extends in a ring shape from the lower end of the cylindrical neck portion 76 in the radial direction outward. On the upper surface of the flange portion 75, an annular fitting groove 75a is formed to fit with the fitting projection 34 provided on the lower surface of the flange portion 32 of the installation member 3 (Fig. 2). The outer diameter of the flange portion 75, the outer diameter of the flange portion 51 of the first vent member 5, and the outer diameter of the second vent member 6 are approximately the same. The inner diameter of the opening 78 of the flange portion 75, the inner diameter of the opening 57 of the first vent member 5 and the inner diameter of the opening 61 of the second vent member 6 are approximately the same ( Figure 2).

The neck portion 76 is formed to fit within the opening 33 of the installation member 3 so that it is formed in the axial direction very slightly longer than the thickness of the flange portion 32 of the installation member 3. In addition, the outer diameter of the neck portion 76 is formed very slightly smaller than the lower flange portion 75 and the upper overhang portion 77.

The overhang portion 77 is an annular convex curved surface whose diameter gradually increases from the upper end of the neck portion 76 toward the bottom, and the maximum diameter portion 77a which is an annular portion having a maximum outer diameter in the overhang portion 77 Through it reaches the first nipple torso (72). On the other hand, the overhang portion 77 may be formed in a flange shape extending radially outward from the upper end of the neck portion 76.

The first nipple body portion 72, the second nipple body portion 73, and the nipple portion 74 are generally conical in shape with the tip of the nipple portion 74 as a whole. The substantially conical midline axis C1 is inclined to the upper jaw side with respect to the central axis C2 of the base 71. In other words, the pacifier body 7 is a rotationally symmetrical bobbin shape in which the lower portion of the base 71, that is, the maximum diameter portion 77a of the overhang portion 77, is centered on the central axis C2. The upper part than the part 77a is inclined substantially like a cone, and shows the shape arrange|positioned on the base 71. As shown in FIG. Therefore, the mammal 1 according to the present invention has a directionality for proper use, and when feeding, it is necessary to be bitten by an infant or toddler so that the right side in FIG. 16 is the upper jaw side. In this embodiment, the inclination angle is 7°, but other angles may be used.

The first nipple body portion 72 and the second nipple body portion 73 are ring-shaped convex curved surfaces that gradually decrease in diameter toward the upper side. Between the first nipple body portion 72 and the second nipple body portion 73 is divided by a first fastening portion 79 made of a concave curved surface in a ring shape. In other words, the first nipple body portion 72 and the second nipple body portion 73, which are all convex curved surfaces, are continuously connected by the first clamping portion 79. Accordingly, the first nipple body portion 72 is divided by the maximum diameter portion 77a of the overhang portion 77 and the first fastening portion 79.

The nipple 74 is substantially spherical, and a perforation 74a (FIG. 14), which is a through hole for feeding, is formed near the top near the upper jaw side. Since the perforation 74a is arranged near the top near the upper jaw side, the beverage released when the infant is breastfeeding is prevented from directly contacting the inside of the throat. The pores 74a are preferably disposed at a position where the released beverage reaches the throat via the upper jaw. A concave curved surface 74b is formed at a portion slightly above the lower jaw side of the nipple portion 74. The concave curved surface 74b is formed at an angle more inclined toward the upper jaw than the central axis C1.

Between the second nipple body portion 73 and the nipple portion 74 is divided by a second fastening portion 80 made of a concave curved surface in a ring shape. In other words, the 2nd nipple body part 73 which is a convex curved surface, and the papillary part 74 which is substantially spherical shape are continuously connected by the 2nd clamping part 80. Therefore, the second nipple torso 73 is divided by the first fastener 79 and the second fastener 80.

Next, while explaining the mammalian motion of the infant and the infant with the pacifier body 7 described, another characteristic of the pacifier body 7 will be described. Infants and toddlers squeeze the beverage from the artificial nipple body 7 by suctioning the peristaltic movement of the tongue. At this time, the infant sends the bulge down the throat while pressing the artificial nipple body 7 with the upper jaw as the tip of the raised tongue. That is, the pacifier main body 7 is pressed while moving its lower chin side from the bottom to the top by the raised portion of the tongue. By adjusting the path of the tongue in the pacifier body 7, that is, the hardness of the region R of the lower jaw portion shown in FIGS. 14 and 15, it is possible to improve the freedom of movement of the tongue. As a result, as a function of the pacifier main body 7 itself, it is possible to induce the peristaltic movement of the infant's tongue, so that the infant and the infant can move more smoothly. This will be described with reference to FIG. 17.

Mammal exercise in infants and toddlers starts from pressing the tip of the raised tongue into the abutment portion 73a, which is the lower jaw portion of the second nipple body portion 73. Therefore, first, it is necessary to form the pacifier main body 7 so that this portion is easy to be pressed. This is realized by the presence of the hollow portion 81 formed by the inner surface of the overhang portion 77 and the inner surface of the first nipple trunk portion 72. That is, when the abutment portion 73a of the second nipple body portion 73 is pressed by the tip of the raised tongue, the upper portion of the first nipple body portion 72 elastically deforms into the cavity portion 81. Subsequently, as the tip of the raised tongue moves upward, the upper portion of the first nipple torso portion 72 is restored, and the restoring force helps the tongue move upward. At this time, inside the artificial nipple body 7, the beverage is gradually compressed toward the nipple portion 74.

The portion to be easily crushed after the second nipple torso portion 73, which is the starting point of the infant's mammalian movement, is the boundary region between the nipple portion 74 and the second tightening portion 80, that is, the nipple portion 74 ) Is the lower portion K of the concave curved surface 74b. This is realized by thinning the front and rear of the portion K of the path through which the tongue passes, ie, the upper portion J of the second clamping portion 80 and the center C of the concave curved surface 74b of the nipple portion 74. By easily forming the lower end portion K of the concave curved surface 74b, the beverage can be efficiently discharged from the pores 74a. In one embodiment, the upper portion J of the second tightening portion 80 is 0.9 mm thick, and the center C of the concave curved surface 74b of the nipple portion 74 is 0.8 mm thick. The lower portion K of the concave curved surface 74b of the head 74 is set to a thickness of 1.3 mm.

Moreover, the infant's mammalian movement is terminated by rising from the tip of the raised tongue to the tip of the papillae 74, and returns to the starting point again. In the case where the entire papillae 74 has a spherical shape, that is, a convex curved surface, The tip of the raised tongue slips just before the end, falls off the path, and the release of the drink may not be good. However, since the nipple portion 74 of the pacifier body 7 has the above-described concave curved surface 74b, it is possible to move the tip of the raised tongue from the diameter of the nipple portion 74 to the end point without falling off. do.

The artificial pacifier body 7 has a variety of characteristic configurations as described above on the path of the infant's tongue, thereby inducing the peristaltic movement of the infant's tongue, so that the infant and the infant can move smoothly.

And, the upper surface of the first nipple body portion 72 and the second nipple body portion 73 is formed to have a smaller protrusion of the convex curved surface than the lower jaw side surface. Therefore, less irregularities are formed in the entire upper jaw side of the pacifier body 7. For this reason, the upper jaw side portion of the pacifier main body 7 is in close contact with the upper jaw of an infant, so that stable mammalian movement can be performed. In addition, since the upper jaw side portion of the pacifier main body 7 is in close contact with the upper jaw of an infant or toddler, it is possible to reliably lower the oral cavity by suction, thereby enabling efficient feeding. Moreover, since the unevenness of the entire upper jaw side of the pacifier main body 7 is small, the upper lip of an infant or toddler is prevented from being rolled into the mouth side due to friction with the pacifier main body 7.

Moreover, the pacifier body 7 is, as described above, about the central axis C2 of the base 71, the central axis C1 of the cone is inclined toward the upper jaw side, so that the pacifier body 7 In the state where the upper jaw side portion is in close contact with the upper jaw of an infant, a wide area and a large cavity 81 can be secured to the lower jaw side of the pacifier body 7. As a result, freedom of movement of the tongue can be improved.

The artificial nipple body 7 is formed of a soft synthetic resin or the like, and thus can be colored in various ways. The conventional pacifier was formed of a transparent or white cloudy silicone resin. However, the pacifier body 7 may be colored in a warm color such as pink or apricot, or other colors. By coloring the entire body of the pacifier 7 and making it a color other than a transparent or white turbid color, confusion with other mammals in a hospital or the like can be prevented and visibility can be improved. Moreover, by coloring in a warm color system, it can contribute to the enhancement of appetite for infants and toddlers, and can make them feel kind and friendly. Moreover, by partially coloring the pacifier main body 7, a figure or a shape can be given to make the pacifier with high design. On the other hand, instead of coloring, imprinting or the like may be used. For example, as shown in Fig. 14, characters such as'UP', which means upward, may be engraved to make it easier to determine the direction during use.

19 is a perspective view showing the fitting of the first ventilation member 5 and the second ventilation member 6. Before assembling the mammal 1, it is first necessary to fit the first vent member 5 and the second vent member 6. That is, as described above, the first ventilation member 5 has three backflow prevention valves 53, 54, and 55 corresponding to the ventilation holes. As described above, under the same pressure difference, since the flow rates obtained by the respective backflow prevention valves 53, 54, and 55 are different, one appropriate backflow prevention valve is selected. The second ventilation member 6 is covered from the top with respect to the first ventilation member 5 to insert the boss portion 65 of the second ventilation member 6 into the fitting hole in which the selected backflow prevention valve is disposed. , Fit is completed. That is, the first ventilation member 5 is fitted in the concave portion 64 of the second ventilation member 6, and at this time, the lower surface of the circumferential wall 63 of the second ventilation member 6 and the first The upper surface of the flange portion 51 of the ventilation member 5 abuts. As a result, one vent hole communicating with the upper and lower portions of the first vent member 5 and the second vent member 6, that is, the vent hole corresponding to the selected backflow prevention valve is obtained. In other words, the first ventilation member 5 and the second ventilation member 6 constitute a flow rate adjustment mechanism. On the other hand, the hollow boss portion 65 and the groove 66 of the second vent member 6, that is, the shape of the vent hole 67, etc. are designed so as not to inhibit the flow of gas through the selected backflow prevention valve.

Moreover, prior to assembly of the mammal 1, the pacifier body 7 is installed with respect to the installation member 3. That is, the artificial nipple body 7 is inserted through the opening 35 and the opening 33 under the installation member 3. At least the outer diameter of the largest diameter portion 77a of the overhang portion 77 of the pacifier body 7 is larger than the inner diameter of the opening 33 of the installation member 3, so that the pacifier body 7 is elastic Insert while deforming. Finally, the pacifier body 7 is inserted until the flange portion 32 of the installation member 3 is disposed on the throat portion 76 of the pacifier body 7. In the state in which the installation of the pacifier body 7 to the installation member 3 is completed (FIG. 2 ), the fitting projection 34 of the flange portion 32 of the installation member 3 is the pacifier body 7. The fitting groove 75a of the flange portion 75 is fitted. Therefore, even if the infant bites and pulls the pacifier body 7 strongly, the pacifier body 7 is not easily removed from the installation member 3.

Here, in the state in which the artificial nipple 2 is installed with respect to the installation member 3, the flange portion 32 of the installation member 3 and the overhang portion 77 of the artificial nipple body 7 are separated. Moreover, since the diameter of the overhang portion 77 gradually increases from the upper end of the neck portion 76 toward the top, the gap between both members is widening toward the outside in the radial direction. With such a configuration, even if the infant bites the pacifier body 7 to the inside, between the flange portion 32 of the installation member 3 and the overhang portion 77 of the pacifier body 7 No lips are caught.

When the final assembling of the mammal 1 is described, first, on the opening end of the mammal 4 main body in which the beverage is put, as described above, for example, the backflow prevention valve 53 is selected and fitted in advance. The first ventilation member 5 and the second ventilation member 6 are placed. Subsequently, the assembly is completed by covering the installation member 3 and the artificial nipple body 7 previously installed from above, and screwing the installation member 3 against the mammalian body 4 (FIG. 2). At this time, the support wall 62 formed on the upper surface of the second ventilation member 6 is in contact with the lower surface of the artificial nipple body 7. Therefore, when the mounting member 3 is screwed to the mammalian body 4, even if it is closed too strongly, the upper surface of the second ventilation member 6 and the lower surface of the artificial nipple body 7 are prevented from being in close contact, The ventilation hole 67 is prevented from being blocked.

When the infant sucks the artificial nipple 2 and the pressure in the mammal 1 decreases, a pressure difference occurs between the inside and outside of the mammal 1. The backflow prevention valve is opened by the pressure difference, passes through the gap between the female screw portion 36 of the installation member 3 and the male screw portion 41 of the mammalian body 4, through the vent hole 67, and finally External air enters the mammal through the backflow prevention valve (53). On the other hand, the presence of the backflow prevention valve 53 prevents the beverage from leaking out of the mammal 1.

20 is a view for explaining the flow rate measurement of the mammal 1 of FIG. 1. In the measurement method, water at room temperature is placed in the mammal 1, and is sucked at a pressure of -13 kPa by a vacuum pump P to measure the flow rate of the sucked water. Water sucked from the mammal 1 is accommodated in the container 100. 26.1 (ml) for the case of passing through the wedge-shaped backflow prevention valve 53, the case of passing through the circular backflow prevention valve 54, and the case of passing through the linear backflow prevention valve 55 /min), 23.3 (ml/min), and 18.0 (ml/min). On the other hand, when the ventilation was not performed in the mammal 1, that is, when the pressure in the mammal 1 continued to decrease, 14.1 (ml/min) resulted.

From the above, according to the suction force at the time of feeding of an infant, the ventilation holes 67 of the second ventilation member 6 are appropriately selected and communicated with respect to the ventilation holes 53, 54, 55 of the first ventilation member 5 By doing so, the flow rate of the gas flowing in from outside the mammal 1 can be adjusted. For example, in the case of infants and toddlers with strong suction power during feeding, the vent holes 55 of the first vent member 5 are selected so that the flow rate of the gas flowing in from outside the mammal 1 is reduced. As a result, the pressure in the mammal 1 reduced by suction rarely rises, so that the amount of drink that an infant or toddler can feed in one feeding operation can be reduced. On the other hand, in the case of infants and toddlers with weak suction power during feeding, the ventilation holes 53 of the first ventilation member 5 are selected so that the flow rate of the gas flowing in from outside the mammal 1 increases. As a result, the pressure in the mammal 1 reduced by suction immediately rises, so that the amount of drink that an infant or toddler can feed in one feeding operation can be increased. Therefore, it can be realized to adjust the proper feeding time or the flow rate of the drink (for example, about 15 to 20 minutes required to drink all the drinks in the mammal) in an easy manner for an infant or toddler. Moreover, since communication of the ventilation holes is achieved by fitting the concave portions (fitting holes) and convex portions (boss portions) of the first ventilation member 5 and the second ventilation member 6, communication of the ventilation holes is achieved. It can be performed more reliably.

On the other hand, the communication of the ventilation holes is not dependent on the fitting of the concave and convex portions of the first ventilation member and the second ventilation member, that is, it has a structure having no convex portions, and may be performed by positioning the ventilation holes of each other. In addition, a plurality of hollow boss portions extending upwardly are installed on the upper surface of the first vent member, and a counterflow prevention valve as described above is installed in the boss part, and through holes are installed and fitted in the corresponding second vent member. You may make it a fitting structure. In addition, since the adjustment of the flow rate under the same pressure difference is substantially the same as the adjustment of the opening area of the vent hole, a non-return valve having a different valve body shape as in the above-described embodiment is not used, and is simply applied to the first vent member A structure may be provided in which a plurality of through holes having different opening areas are provided. Moreover, when the first ventilation member has a plurality of through holes having different opening areas, a configuration may be provided in which the backflow prevention valve is provided only in the hollow boss portion of the second ventilation member. In the above-described embodiment, in the above-described flow rate adjustment mechanism, three adjustable ventilation holes may be used, but two or four or more may be used.

The above-described features of the pacifier body are applicable not only to the above-described mammalian machine, but also to a conventional mammalian machine.
