Description

本発明は、例えば乳幼児等が授乳等に際し利用する人工乳首及び哺乳器に関するものである。   The present invention relates to an artificial nipple and a sucker used by, for example, infants when breastfeeding.

従来より、搾乳した母乳や、調乳したミルク等を収容した容器に、キャップを介して人工乳首を取り付け哺乳器として使用している。
このような哺乳器は、人工乳首の先端側に先端開口が形成されているため、乳幼児等が人工乳首をくわえ、舌による蠕動様運動を行うことで、容器内のミルク等を摂取できる構成となっている。
また、人工乳首には、外方に突出するように成るフランジが周状に配置され、このフランジがキャップと容器との間に挟まれることで、人工乳首が容器に固定される構成となっている。 Conventionally, an artificial nipple is attached to a container containing milked breast milk, prepared milk, or the like via a cap and used as a sucker.
Since such a sucker has a tip opening formed on the tip side of the artificial nipple, an infant or the like holds the artificial nipple and performs a peristaltic movement with the tongue, so that the milk in the container can be ingested. It has become.
In addition, the artificial nipple has a configuration in which a flange that protrudes outward is arranged in a circumferential shape, and the artificial nipple is fixed to the container by sandwiching the flange between the cap and the container. Yes.

しかし、乳幼児等が容器内のミルク等を摂取し続けると、容器内のミルク量が減少し、哺乳器の内部が外気に比べ負圧となり、ミルク等を先端開口から摂取し難くなる。
このため、例えば特許文献１に示すように、人工乳首のフランジに通気孔を形成することで、哺乳器内部の負圧を解消する構成となっている。
特開２００４−１２９９４０号公報（図３等） However, if an infant or the like keeps ingesting milk or the like in the container, the amount of milk in the container decreases, the inside of the sucker becomes negative pressure compared to the outside air, and it becomes difficult to ingest milk or the like from the tip opening.
For this reason, as shown, for example in patent document 1, it is the structure which eliminates the negative pressure inside a nursing bottle by forming a ventilation hole in the flange of an artificial nipple.
JP 2004-129940 A (FIG. 3 etc.)

しかしながら、例えば人工乳首を乳幼児等の舌による蠕動様運動で伸展するような硬度の低い柔らかい材質で形成すると、人工乳首のフランジをキャップで固定する際、フランジが変形し、これによりフランジに形成されている通気孔も変形するため、通気孔が確実に機能せず、哺乳器内の負圧が解消しないという問題があった。
このような哺乳器内の負圧を解消するために、特許文献１に示す人工乳首のフランジの通気孔の開口を大きくすることが考えられる。
しかし、通気孔の開口を大きく形成すると、通気孔の開口から容器内のミルク等の液体が漏れ出すという問題が生じる。 However, for example, if the artificial nipple is formed of a soft material with low hardness such that the artificial nipple is stretched by a peristaltic movement of the tongue of an infant or the like, the flange is deformed when the flange of the artificial nipple is fixed with a cap, thereby forming the flange. Since the vent hole is also deformed, there is a problem that the vent hole does not function reliably and the negative pressure in the sucker is not eliminated.
In order to eliminate such negative pressure in the nursing bottle, it is conceivable to enlarge the opening of the vent hole of the flange of the artificial nipple shown in Patent Document 1.
However, if the opening of the vent hole is formed large, there arises a problem that liquid such as milk in the container leaks from the opening of the vent hole.

そこで、硬度の低い材質で成る人工乳首であっても、容器内の液体が漏れ出すことなく、容器内の負圧を円滑に解消できる人工乳首及び哺乳器を提供することを目的とする。   Accordingly, an object of the present invention is to provide an artificial nipple and a sucker that can smoothly eliminate the negative pressure in the container without leaking the liquid in the container even if the nipple is made of a material having low hardness.

前記課題は、請求項１の発明により達成される。すなわち、請求項１の構成によれば、座板部には容器等の内部の負圧を解消するための貫通孔が形成されているので、人工乳首が固定される容器等の内部の負圧を解消することができる。
また、人工乳首は硬度（ＪＩＳ−Ｋ６２３５（ＩＳＯ７６１９）におけるＡ型デュロメータによる硬度）５度乃至３０度という柔らかい弾性材料から成っているため、アダプタ部材により座板部を容器に固定する際、アダプタ部材の移動により座板部が変形するおそれがある。
そして、座板部の変形により、座板部に形成されている貫通孔が変形し、容器等の内部の負圧を解消できないおそれがある。しかし、本発明では、座板部には、複数の貫通孔が形成されているため、一方の貫通孔が変形し負圧解消の機能を発揮できなくても、他方の貫通孔で容器等の内部の負圧を解消することができる。したがって、確実に容器等内の負圧を解消できる構成となっている。
また、複数の貫通孔は、それぞれの孔径が０．１ｍｍ乃至０．２ｍｍという小さい孔径と成っているため、各貫通孔から容器内の液体が漏れ出すことがなく、また、固形物等で目詰まりを起こすこともない。
以上のように、本発明では、硬度の低い材質で成る人工乳首であっても、容器内の液体が貫通孔から漏れ出すことがなく、容器内の負圧を円滑に解消することができる人工乳首である。 The object is achieved by the invention of claim 1. That is, according to the structure of Claim 1, since the through-hole for eliminating the negative pressure inside a container etc. is formed in the seat board part, the negative pressure inside a container etc. to which an artificial teat is fixed is formed. Can be eliminated.
Further, since the artificial nipple is made of a soft elastic material having a hardness (hardness by an A-type durometer in JIS-K6235 (ISO7619)) of 5 to 30 degrees, the adapter member is used when the seat plate is fixed to the container by the adapter member. There is a possibility that the seat plate portion is deformed by the movement of the.
And the deformation | transformation of a seat plate part deform | transforms the through-hole currently formed in the seat plate part, and there exists a possibility that the negative pressure inside containers etc. cannot be eliminated. However, in the present invention, since a plurality of through holes are formed in the seat plate portion, even if one through hole is deformed and the function of eliminating the negative pressure cannot be exhibited, the other through hole can be used for a container or the like. The internal negative pressure can be eliminated. Accordingly, the negative pressure in the container or the like can be reliably eliminated.
In addition, since the plurality of through holes have small diameters of 0.1 mm to 0.2 mm, the liquid in the container does not leak from each through hole, and it is not There is no clogging.
As described above, in the present invention, even in an artificial nipple made of a material with low hardness, the liquid in the container does not leak from the through hole, and the artificial negative pressure in the container can be eliminated smoothly. It is a nipple.

好ましくは、請求項２の発明の構成によれば、座板部は、アダプタ部材と容器に挟持され、アダプタ側ネジ部と容器側ネジ部とが螺合されることにより固定される。このため、アダプタ部と容器との螺合の際、一の貫通孔が変形した場合、その近傍に他の貫通孔を配置しても、同様に変形する可能性が高い。
そこで、本発明では、一の貫通孔から座板部の円周に沿って両側に９０°（度）以上、離間した位置に他の貫通孔を配置している。これにより、一の貫通孔と他の貫通孔との間の距離が十分に離れるため、一の貫通孔と同様の影響を受けにくい。すなわち、一の貫通孔が変形等しても、他の貫通孔は変形等することなく貫通孔として機能させることができる構成となっている。 Preferably, according to the configuration of the invention of claim 2, the seat plate portion is sandwiched between the adapter member and the container, and is fixed by screwing the adapter side screw portion and the container side screw portion. For this reason, in the case where one through hole is deformed when the adapter portion and the container are screwed together, there is a high possibility that the same deformation occurs even if another through hole is disposed in the vicinity thereof.
Therefore, in the present invention, other through holes are arranged at positions spaced from each other by 90 ° (degrees) or more on both sides along the circumference of the seat plate portion from one through hole. Thereby, since the distance between one through-hole and another through-hole is fully separated, it is hard to receive the influence similar to one through-hole. That is, even if one through-hole is deformed, the other through-hole can function as a through-hole without being deformed.

好ましくは、請求項３の発明の構成によれば、複数の貫通孔が中央部を中心とした対称位置に配置されているので、貫通孔を座板部に形成する際に、形成し易い構成となっている。   Preferably, according to the configuration of the invention of claim 3, since the plurality of through holes are arranged at symmetrical positions with the central portion as the center, a configuration that is easy to form when forming the through holes in the seat plate portion. It has become.

好ましくは、請求項４の発明に構成によれば、流出口部の開口の直径が０．５５ｍｍ以上と成っている。人工乳首の先端側等に形成されている流出口部は、普通サイズの場合、その開口の直径は０．３ｍｍ乃至０．４５ｍｍと成っている。これは月齢では例えば、０ヶ月乃至８ヶ月程度の乳児等が使用する場合である。
そして、乳幼児等が更に成長し、ミルク等の摂取量が増え、飲む時間が長くなると人工乳首の流出口部の開口を大きくする必要が生じる。
本請求項に係る流出口部の開口は、このように、ミルク等の摂取量が増えた場合に使用される、いわゆるＬサイズの流出口部に該当する。
ところで、流出口部の開口が大きくなると、小さい場合に比べ、ミルク等が流出口部から排出された後の容器等の内部に生じる負圧がより高まることになる。
この場合、貫通孔が１つで、漏れを防ぐため等の理由で孔径が０．１ｍｍ乃至０．２ｍｍと小さいときは、負圧の大きさに比べ、孔径が小さすぎるため、十分に容器等内の負圧を解消できなかった。
しかし、本発明では、貫通孔が複数あるため、たとえ各貫通孔の孔径が小さくても、複数の貫通孔で負圧を解消することができる構成となっている。
このように、本発明では、例え摂取量が増えた場合であっても、容器等の内部の負圧を円滑に解消しつつ、同時に容器内の液体が貫通孔から漏れ出さない構成となっている。 Preferably, according to the fourth aspect of the present invention, the diameter of the opening of the outlet portion is 0.55 mm or more. In the case of a normal size, the outlet portion formed on the tip side of the artificial nipple has an opening diameter of 0.3 mm to 0.45 mm. This is the case when the infant is about 0 to 8 months old.
As infants and the like grow further, the intake of milk and the like increases, and the time for drinking becomes longer, it becomes necessary to enlarge the opening of the outlet of the artificial nipple.
The opening of the outlet part according to the present claim corresponds to a so-called L-size outlet part used when the intake amount of milk or the like is increased.
By the way, when the opening of the outlet portion becomes larger, the negative pressure generated inside the container or the like after milk or the like is discharged from the outlet portion becomes higher than when the opening is small.
In this case, when the hole diameter is as small as 0.1 mm to 0.2 mm for the purpose of preventing leakage, etc., the hole diameter is too small compared to the negative pressure, so that the container etc. The internal negative pressure could not be resolved.
However, in the present invention, since there are a plurality of through holes, the negative pressure can be eliminated by the plurality of through holes even if the diameter of each through hole is small.
Thus, in the present invention, even if the intake amount is increased, the internal negative pressure of the container or the like is smoothly eliminated, and at the same time, the liquid in the container does not leak from the through hole. Yes.

前記課題は請求項５の発明によれば、請求項１の構成を有する哺乳器により達成される。   According to the invention of claim 5, the object is achieved by a sucker having the configuration of claim 1.

本発明は、硬度の低い材質で成る人工乳首であっても、容器内の液体が漏れ出すことなく、容器内の負圧を円滑に解消できる人工乳首及び哺乳器を提供できるという利点がある。   The present invention has an advantage that even an artificial nipple made of a material having low hardness can provide an artificial nipple and a sucker that can smoothly eliminate the negative pressure in the container without leaking the liquid in the container.

以下、この発明の好適な実施の形態を添付図面等を参照しながら、詳細に説明する。
尚、以下に述べる実施の形態は、本発明の好適な具体例であるから、技術的に好ましい種々の限定が付されているが、本発明の範囲は、以下の説明において特に本発明を限定する旨の記載がない限り、これらの態様に限られるものではない。 Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

（哺乳器１００の全体構成等について）
図１は、本発明の実施の形態に係る哺乳器１０の構成を示す概略図である。図１に示すように、哺乳器１０は、搾乳した母乳や調整ミルク等の液体を収容するためのガラス製又は樹脂製の容器である例えば、哺乳瓶１１を有している。また、哺乳器１０は、弾性材料である例えば、シリコーンゴムやイソプレンゴムから成っている人工乳首１００を有している。
また、哺乳器１０は、人工乳首１００を哺乳瓶１１に対して固定するためのアダプタ部材である例えば、樹脂製のキャップ１２を有していると共に、哺乳瓶１１にキャップ１２を介して取り付けられた人工乳首１００を覆うためのフード１３も有している。 (About the overall configuration of the baby 100)
FIG. 1 is a schematic diagram showing the configuration of a baby sucker 10 according to an embodiment of the present invention. As shown in FIG. 1, the baby bottle 10 has, for example, a baby bottle 11 that is a glass or resin container for containing a liquid such as milk milk or adjusted milk. The baby bottle 10 has an artificial nipple 100 made of an elastic material such as silicone rubber or isoprene rubber.
The feeding bottle 10 has, for example, a resin cap 12 that is an adapter member for fixing the artificial nipple 100 to the feeding bottle 11 and is attached to the feeding bottle 11 via the cap 12. A hood 13 for covering the artificial nipple 100 is also provided.

（人工乳首１００等について）
図２は、図１の人工乳首１００の概略図であり、図３は、図２の概略平面図であり、図４は、図３のＡ−Ａ’線概略断面図である。図２に示す人工乳首１００は、図４に示すように内部が中空と成っていると共に、全体が、硬度（ＪＩＳ−Ｋ６２３５（ＩＳＯ７６１９）におけるＡ型デュロメータによる硬度）が５度乃至３０度、例えば１５度乃至２５度のシリコーンゴムで形成されている。
本実施の形態の人工乳首１００を、使用者である乳幼児等が口腔内に入れると、図４の人工乳首１００の先端側が、口腔内の哺乳窩に当接する。そして、この状態で、乳幼児等の舌が図４の人工乳首１００の壁面１１０に当接し、蠕動様運動を行うと、人工乳首１００が伸展（伸長）する構成となっている。
これは、母乳授乳時における母親の乳首が、乳幼児等の舌の蠕動様運動で伸展していることが近年研究により判明したこと基づき、より人間の乳首に近い動きをする人工乳首１００とするための構成である。 (About artificial nipples 100 etc.)
2 is a schematic view of the artificial nipple 100 of FIG. 1, FIG. 3 is a schematic plan view of FIG. 2, and FIG. 4 is a schematic cross-sectional view taken along line AA ′ of FIG. The artificial teat 100 shown in FIG. 2 has a hollow inside as shown in FIG. 4 and the whole has a hardness (hardness according to A-type durometer in JIS-K6235 (ISO7619)) of 5 to 30 degrees, for example, It is made of silicone rubber at 15 to 25 degrees.
When an infant or the like who is a user puts the artificial nipple 100 of the present embodiment into the oral cavity, the distal end side of the artificial nipple 100 in FIG. 4 comes into contact with the nursing cavity in the oral cavity. In this state, when the tongue of an infant or the like comes into contact with the wall surface 110 of the artificial nipple 100 of FIG. 4 and performs a peristaltic movement, the artificial nipple 100 is extended (elongated).
This is because an artificial nipple 100 that moves more like a human nipple is based on recent studies that the mother's nipple during breastfeeding has been extended by a peristaltic movement of the tongue of an infant or the like. It is the composition.

すなわち、本実施の形態の人工乳首１００は、乳幼児等の舌による蠕動様運動で伸展可能な程度の柔らかさを有する必要があり、そのため、例えば硬度１５度乃至２５度のシリコーンゴムで形成されている。
また、図４に示すように、人工乳首１００の内側には、溝状の凹部１２０がリング状に２カ所形成されている。凹部１２０の肉厚が薄くなることで、人工乳首１００は乳幼児等の舌の蠕動様運動で、より先端側に向かって伸展し易い構成となっている。
なお、このような凹部１２０が形成されていない、内面が平滑状とされた人工乳首とされていてもよいのはもちろんである。 That is, the artificial nipple 100 according to the present embodiment needs to have a softness that can be extended by a peristaltic movement by the tongue of an infant or the like. For this reason, the artificial nipple 100 is formed of, for example, silicone rubber having a hardness of 15 degrees to 25 degrees. Yes.
In addition, as shown in FIG. 4, two groove-shaped recesses 120 are formed inside the artificial nipple 100 in a ring shape. By reducing the thickness of the recess 120, the artificial nipple 100 is configured to easily extend toward the distal end side due to the peristaltic movement of the tongue of an infant or the like.
Of course, it may be an artificial nipple having a smooth inner surface, in which such a recess 120 is not formed.

人工乳首１００には、図３及び図４に示すように、その先端部に流出口部である例えば、センタ孔１３０が形成されている。センタ孔１３０は、人工乳首１００の内部と連通する構成と成っているので、図１の哺乳瓶１１内に収容された調整ミルク等が人工乳首１００の内部空間に達すると、その後、センタ孔１３０から流出し、人工乳首１００からの摂取が行える構成となっている。
なお、人工乳首１００の壁面１１０及びセンタ孔１３０等により、図４に示す乳首本体１０１が形成される。 As shown in FIGS. 3 and 4, the artificial nipple 100 is formed with, for example, a center hole 130 as an outflow portion at the tip thereof. Since the center hole 130 is configured to communicate with the inside of the artificial nipple 100, when the adjusted milk or the like accommodated in the baby bottle 11 of FIG. It can be taken out from the artificial nipple 100.
The nipple body 101 shown in FIG. 4 is formed by the wall surface 110, the center hole 130, and the like of the artificial nipple 100.

このような乳首本体１０１の図４の下方側には、図３及び図４に示すように、円周状に形成される座板部１０２が形成されている。
座板部１０２には、図３に示すように、例えば２個の薄肉状の凹部とされた段部１０２ａ，１０２ｂが形成されており、段部１０２ａ，１０２ｂの中央に複数の貫通孔である例えば、２個の通気孔１０３ａ、１０３ｂが形成されている。また、２個の通気孔１０３ａ等は略円形の開口と成っており、各通気孔１０３ａ等の孔径は、それぞれ０．１ｍｍ乃至０．２ｍｍの大きさと成っている。 As shown in FIGS. 3 and 4, a seat plate portion 102 formed in a circumferential shape is formed on the lower side of FIG. 4 of the nipple main body 101.
As shown in FIG. 3, for example, two thin-walled step portions 102a and 102b are formed in the seat plate portion 102, and there are a plurality of through holes in the center of the step portions 102a and 102b. For example, two vent holes 103a and 103b are formed. The two air holes 103a and the like are substantially circular openings, and the diameters of the air holes 103a and the like are each 0.1 mm to 0.2 mm.

通気孔１０３ａ等は、以下のような働きをする。すなわち、図１に示す人工乳首１００をキャップ１２を介して哺乳瓶１１に装着すると、哺乳器１０内はセンタ孔１３０を除き、密閉状態となる。この状態で乳幼児がセンタ孔１３０から調整ミルクを摂取すると、哺乳器１０内は、外気に対し負圧となり、摂取し難くなる。
そこで、人工乳首１００の座板部１０２に通気孔１０３ａ等を設け、この通気孔１０３ａ等を介して外気と連通することで、哺乳器１０内の負圧を解消する構成となっている。 The air holes 103a and the like function as follows. That is, when the artificial nipple 100 shown in FIG. 1 is attached to the baby bottle 11 via the cap 12, the inside of the baby bottle 10 is in a sealed state except for the center hole 130. When the infant takes the adjusted milk from the center hole 130 in this state, the inside of the baby bottle 10 becomes a negative pressure with respect to the outside air, and it becomes difficult to take it.
Therefore, a vent hole 103a and the like are provided in the seat plate portion 102 of the artificial nipple 100 and communicated with the outside air through the vent hole 103a and the like, thereby eliminating the negative pressure in the sucker 10.

各通気孔１０３ａ等は、図３に示すように、円周状に形成されている座板部１０２の円周形状に沿って、相互に離間して配置されている。具体的には、一の貫通孔である例えば、通気孔１０３ａから人工乳首１００の中央部に向けて配置した第１の仮想線Ｉ１と、他の貫通孔である例えば、通気孔１０３ｂから人工乳首１００の中央部に向けて配置した第２の仮想線Ｉ２とで形成される角度が１８０°（度）となり、通気孔１０３ａ、１０３ｂは、人工乳首１００の図３における中央部を中心とした対称位置に配置されている。
なお、一の貫通孔からの第１の仮想線Ｉ１に対して、他の貫通孔からの第２の仮想線で形成される角度は９０度乃至２７０度の範囲であればよく、他の貫通孔を９０度の位置に配置してもよい。
さらに、貫通孔を３箇所形成し、一の貫通孔における第１の仮想線Ｉ１に対して、二及び三の貫通孔をそれぞれ１２０度離間した位置に配置するよう構成してもよく、通気量を考慮すると貫通孔は２箇所乃至３箇所であることが好ましい。 As shown in FIG. 3, the air holes 103 a and the like are arranged away from each other along the circumferential shape of the seat plate portion 102 formed in a circumferential shape. Specifically, for example, the first imaginary line I1 arranged from one vent hole toward the center of the artificial nipple 100 from the vent hole 103a and the other pierced hole such as the vent hole 103b to the artificial nipple. The angle formed by the second imaginary line I2 arranged toward the central portion of 100 is 180 ° (degrees), and the vent holes 103a and 103b are symmetrical with respect to the central portion of the artificial nipple 100 in FIG. Placed in position.
The angle formed by the second imaginary line from the other through hole with respect to the first imaginary line I1 from the one through hole may be in the range of 90 degrees to 270 degrees. You may arrange | position a hole in the 90-degree position.
Furthermore, three through holes may be formed, and the two and three through holes may be arranged at positions 120 degrees apart from the first virtual line I1 in one through hole. In consideration of the above, it is preferable that the number of through holes is two to three.

また、図３に示すセンタ孔１３０の開口は略円形となっており、その開口の直径が０．５５ｍｍ以上とされた比較的流量が大きなサイズとなっている。すなわち、発達状態にもよるが、乳幼児の月齢が０ヶ月乃至８ヶ月程度の場合は、調整ミルク等の摂取量が少なく、その分、センタ孔１３０の開口の直径は、０．３ｍｍ乃至０．４５ｍｍ程度で十分である。
しかし、乳幼児が月齢を重ね成長してくると、調整ミルク等の摂取量が増え、センタ孔の径が０．３ｍｍ乃至０．４５ｍｍでは、開口面積が小さすぎて、時間が必要となるなど十分に調整ミルクを摂取できない。そこで、本実施の形態では、センタ孔の開口面積を大きくするため、孔径を０．５５ｍｍ以上、例えば０．６５mmとし、成長した乳幼児でも円滑に哺乳瓶１１内の調整ミルクを摂取できるように構成されている。
なお、センタ孔径を０．３ｍｍ乃至０．４５ｍｍ程度の通常の人工乳首とした場合でも、上述のような通気孔を設けることで、確実に通気を行うことができる。 Further, the opening of the center hole 130 shown in FIG. 3 has a substantially circular shape, and the diameter of the opening is 0.55 mm or more, and the flow rate is relatively large. That is, although depending on the developmental state, when the infant is about 0 to 8 months old, the intake of the adjusted milk or the like is small, and the diameter of the opening of the center hole 130 is 0.3 mm to 0.00 mm. About 45 mm is sufficient.
However, as infants grow older, the intake of adjusted milk and the like increases, and if the center hole diameter is 0.3 mm to 0.45 mm, the opening area is too small and time is required. I can't get adjusted milk. Therefore, in the present embodiment, in order to increase the opening area of the center hole, the hole diameter is set to 0.55 mm or more, for example, 0.65 mm, so that even a grown-up infant can smoothly take the adjusted milk in the baby bottle 11. Has been.
Even when a normal artificial nipple having a center hole diameter of about 0.3 mm to 0.45 mm is provided, ventilation can be reliably performed by providing the ventilation holes as described above.

また、図４に示すように、人工乳首１００の内部の中空部分の内径は２５ｍｍ乃至３０ｍｍ程度、ここでは２７ｍｍで、人工乳首１００の座板部１０２等を除く、乳首本体１０１の高さが、３３．５ｍｍと成っている。この内径は、高さに比して大きく形成されているため、このような人工乳首を広口径乳首と称している。
すなわち、乳首本体１０１の高さが３３．５ｍｍ程度の場合、広口径乳首でない、通常の人工乳首の内径は、１８ｍｍ程度である。
つまり、広口径乳首では、乳首本体１０１の高さに対する人工乳首１００の内径は７５％乃至９０％程度とされているが、通常の人工乳首では５５％程度とされている。
そのため、広口径乳首では内径が大きく、人工乳首１００が取り付けられたキャップ１２を哺乳瓶１１に装着する際に、座板部１０２に歪みが生じ易く、ひいては貫通孔による通気を確実に行い難くなる傾向が高くなる。さらに、広口径乳首とされている場合、高さ方向に対する剛性が弱くなるため、通気が行われず、哺乳器１０内の負圧が高まった場合に乳首本体１１０が哺乳器１０内に入り込んでしまうおそれもあった。 Further, as shown in FIG. 4, the inner diameter of the hollow portion inside the artificial nipple 100 is about 25 mm to 30 mm, here 27 mm, and the height of the nipple body 101 excluding the seat plate portion 102 of the artificial nipple 100 is It is 33.5 mm. Since this inner diameter is larger than the height, such an artificial nipple is referred to as a wide-bore nipple.
That is, when the height of the nipple body 101 is about 33.5 mm, the inner diameter of a normal artificial nipple that is not a wide-diameter nipple is about 18 mm.
That is, in the wide-diameter nipple, the inner diameter of the artificial nipple 100 with respect to the height of the nipple body 101 is about 75% to 90%, but in the normal artificial nipple, it is about 55%.
For this reason, the wide-diameter nipple has a large inner diameter, and when the cap 12 to which the artificial nipple 100 is attached is attached to the baby bottle 11, the seat plate portion 102 is likely to be distorted, and thus it is difficult to reliably vent the through hole. The tendency becomes higher. Further, when the nipple is a wide-diameter nipple, the rigidity in the height direction is weakened, so that ventilation is not performed and the nipple body 110 enters the sucker 10 when the negative pressure in the sucker 10 increases. There was also a fear.

（キャップ１２と哺乳瓶１１との螺合等について）
図１に示すように、哺乳瓶１１の開口に近傍には、容器側ネジ部である例えば、雄ねじ１１ａが形成されている。また、キャップ１２の内側には、雄ねじ１１ａに対応する容器側ネジである例えば、雌ねじ１２ａが形成されている。
図５は、図１の人工乳首１００の座板部１０２とキャップ１２との関係を示す概略説明図である。図１及び図５に示すように、人工乳首１００は、その座板部１０２がキャップ１２と哺乳瓶１１の開口上面とに挟まれることで、哺乳瓶１１に対して固定される構成となっている。
すなわち、キャップ１２の雌ねじ１２ａと哺乳瓶１１の雄ねじ１１ａとが螺合される際、人工乳首１００の座板部１０２がキャップ内面と哺乳瓶開口端に挟まれて固定される。
また、座板部１０２上面とキャップ１２内面は、ごく僅かな隙間が形成されており、さらに乳幼児が乳首本体１１０をくわえた際や、哺乳器１０内の圧力が負圧となることに伴って、人工乳首１００が僅かに変形し、通気孔１０３ａが外気と連通することとなる。 (About screwing between the cap 12 and the baby bottle 11)
As shown in FIG. 1, for example, a male screw 11 a that is a container-side screw portion is formed in the vicinity of the opening of the baby bottle 11. In addition, for example, a female screw 12a that is a container side screw corresponding to the male screw 11a is formed inside the cap 12.
FIG. 5 is a schematic explanatory view showing the relationship between the seat plate portion 102 and the cap 12 of the artificial nipple 100 of FIG. As shown in FIGS. 1 and 5, the artificial nipple 100 is configured to be fixed to the baby bottle 11 by the seat plate portion 102 being sandwiched between the cap 12 and the upper opening surface of the baby bottle 11. Yes.
That is, when the female screw 12a of the cap 12 and the male screw 11a of the baby bottle 11 are screwed together, the seat plate portion 102 of the artificial nipple 100 is sandwiched and fixed between the cap inner surface and the baby bottle opening end.
In addition, a very small gap is formed between the upper surface of the seat plate portion 102 and the inner surface of the cap 12, and when the infant holds the nipple body 110 or when the pressure in the baby bottle 10 becomes negative. The artificial nipple 100 is slightly deformed and the vent hole 103a communicates with the outside air.

本実施の形態に係る哺乳器１０は、以上のように構成されている。そして、使用者である例えば、母親が哺乳器１００を使用する際は、哺乳瓶１１内に調整ミルクを入れる。このとき、母親は、図１に示すように、人工乳首１００の座板部１０２にキャップ１２を被せ、キャップ１２の内側の雌ねじを哺乳瓶１１の雄ねじ１１ａに対して螺合させる。
この際、人工乳首１００の座板部１０２は、哺乳瓶１１の上面に当接した状態で、キャップ１２により回転方向に力が加わる。人工乳首１００は上述のように硬度２０度前後の柔らかいシリコーンゴムから成っているため、この力により座板部１０２が変形し、座板部１０２に形成されている通気孔１０３ａの開口を塞いでしまうことがある。このとき、通気孔が１つでは、哺乳器内の負圧が解消されず、乳幼児が哺乳瓶１１内の調整ミルクを摂取し難くなるおそれがある。
しかし、本実施の形態では、通気孔１０３ｂも形成されており、通気孔１０３ｂで外気と連通されるので、哺乳器１０内の負圧がこの通気孔１０３ｂで解消される構成となっている。 The sucker 10 according to the present embodiment is configured as described above. For example, when the mother who is the user uses the baby bottle 100, the adjusted milk is put into the baby bottle 11. At this time, as shown in FIG. 1, the mother puts the cap 12 on the seat plate portion 102 of the artificial nipple 100 and screwes the female screw inside the cap 12 with the male screw 11 a of the baby bottle 11.
At this time, the seat plate portion 102 of the artificial nipple 100 is applied with a force in the rotational direction by the cap 12 in a state of being in contact with the upper surface of the baby bottle 11. Since the artificial nipple 100 is made of soft silicone rubber having a hardness of around 20 degrees as described above, the seat plate portion 102 is deformed by this force and blocks the opening of the vent hole 103a formed in the seat plate portion 102. It may end up. At this time, if there is one vent hole, the negative pressure in the baby bottle cannot be eliminated, and it may be difficult for the infant to take the adjusted milk in the baby bottle 11.
However, in the present embodiment, the vent hole 103b is also formed and communicates with the outside air through the vent hole 103b, so that the negative pressure in the sucker 10 is eliminated by the vent hole 103b.

また、本実施の形態では、通気孔１０３ａ等は孔径が０．１ｍｍ乃至０．２ｍｍという小さい径で形成されているので、通気孔１０３ａ等から哺乳瓶１１内の調整ミルクが漏れ出すことがなく、また目詰まりを起こすことがない。つまり、０．１ｍｍ未満の場合、調整ミルク等に混入している固形物によって通気孔１０３ａが目詰まりを起こすおそれがあり、通気ができなくなってしまうおそれがある。また、０．２ｍｍよりも大きい場合、漏れ出てしまうおそれがある。
このように、本実施の形態では、硬度が低く柔らかいシリコーンゴムでなる人工乳首１００であっても、哺乳瓶１１内の調整ミルクを通気孔１０３ａ等から漏れ出させることなく、哺乳器１０内の負圧を円滑に解消することができる。 In the present embodiment, since the vent hole 103a and the like are formed with a small diameter of 0.1 mm to 0.2 mm, the adjusted milk in the baby bottle 11 does not leak from the vent hole 103a or the like. In addition, there is no clogging. In other words, when the diameter is less than 0.1 mm, the air holes 103a may be clogged by solid matter mixed in the adjusted milk or the like, and there is a possibility that ventilation cannot be performed. Moreover, when larger than 0.2 mm, there exists a possibility of leaking.
Thus, in this embodiment, even in the artificial nipple 100 made of soft silicone rubber with low hardness, the adjusted milk in the baby bottle 11 is not leaked from the vent hole 103a or the like, Negative pressure can be eliminated smoothly.

また、図３に示すように、通気孔１０３ａと通気孔１０３ｂとは、１８０°（度）離間して配置されている。これにより、両者の間隔は十分広がるため、例え通気孔１０３ａが座板部１０２の変形により塞がれても、他の通気孔１０３ｂは、その変形の影響を受けにくい。したがって、他の通気孔１０３ｂで哺乳器１０内の負圧を解消することができる。
また、図３に示すように、通気孔１０３ａと通気孔１０３ｂとは、人工乳首１００の中央部（図３のセンタ孔１３０）を中心に対称位置に配置されている。このため、人工乳首１００の製造工程において、通気孔１０３ａ等を容易に形成することができる。
なお、本実施の形態では、通気孔１０３ａと通気孔１０３ｂとを１８０°（度）離間させて配置したが、これに限らず、通気孔１０３ａから９０°（度）乃至２７０°（度）の範囲に形成してもよい。
すなわち、図３の矢印Ｒの範囲内であれば、通気孔１０３ｂは通気孔１０３ａと十分離間して配置されるので、通気孔１０３ａが受けた座板部１０２の変形の影響を回避できる構成となっている。 Also, as shown in FIG. 3, the vent hole 103a and the vent hole 103b are arranged 180 degrees (degrees) apart. As a result, the distance between the two is sufficiently widened, so that even if the vent hole 103a is blocked by the deformation of the seat plate portion 102, the other vent holes 103b are not easily affected by the deformation. Therefore, the negative pressure in the sucker 10 can be eliminated by the other vent 103b.
Further, as shown in FIG. 3, the vent hole 103a and the vent hole 103b are arranged at symmetrical positions around the central portion of the artificial nipple 100 (center hole 130 in FIG. 3). For this reason, the vent 103a etc. can be formed easily in the manufacturing process of the artificial nipple 100.
In the present embodiment, the vent hole 103a and the vent hole 103b are arranged 180 degrees (degrees) apart from each other. However, the present invention is not limited to this. You may form in a range.
That is, as long as it is within the range of the arrow R in FIG. 3, the vent hole 103b is disposed sufficiently away from the vent hole 103a, so that the influence of deformation of the seat plate portion 102 received by the vent hole 103a can be avoided. It has become.

また、本実施の形態ではセンタ孔１３０が０．５５ｍｍ以上と大きくなっている。このような孔径が大きい人工乳首１００は、月齢が高い乳幼児が使用すると共に、哺乳器１０内に発生する負圧も大きくなる。
すなわち、センタ孔が小さい場合より、通気孔による外気との連通面積を大きくとる必要がある。しかし、通気孔の開口面積を大きくすると、その分哺乳瓶１１内の調整ミルク等の漏れの原因となるという問題がある。
しかし、本実施の形態では、通気孔１０３ａ等を２カ所形成し、それぞれの通気孔１０３ａ等の開口面積を大きくしないことで、調整ミルクの漏れ防止と、負圧の解消を同時に達成できる哺乳器１０となっている。 In the present embodiment, the center hole 130 is as large as 0.55 mm or more. Such an artificial nipple 100 having a large hole diameter is used by infants with a high age, and the negative pressure generated in the baby bottle 10 also increases.
That is, it is necessary to take a larger communication area with the outside air through the vent hole than when the center hole is small. However, when the opening area of the vent hole is increased, there is a problem that it causes leakage of adjusted milk or the like in the baby bottle 11.
However, in the present embodiment, a baby bottle that can achieve the prevention of leakage of adjusted milk and the elimination of negative pressure at the same time by forming two vent holes 103a etc. and not increasing the opening area of each vent hole 103a etc. It is 10.

図６は、本実施の形態に係る哺乳器１０と従来の哺乳器との比較例を示す表である。
従来の哺乳器と本実施の形態の哺乳器１０の人工乳首は、共に硬度２２度、哺乳瓶に対するキャップの締めトルクは１００Ｎである。
そして、従来の哺乳器の人工乳首の座板部には通気孔が１カ所のみ形成されているが、本実施の形態の哺乳器１０では、図３に示すように、２カ所形成した。
そして、両者共、人工乳首のセンタ孔から大気圧基準の−２６．６ｋＰａで吸引した。
その結果、本実施の形態では、図６に示すように、哺乳瓶内の負圧は大きく解消されたが、従来の哺乳器では、負圧が解消されにくかった。
また、本実施の形態では、負圧の解消により調整ミルクの流量も増えた。すなわち、本実施の形態の人工乳首１００は、月齢が高く、調整ミルクの摂取量が多い、乳幼児でも使用しやすい人工乳首であることが実際に検証された。 FIG. 6 is a table showing a comparative example of the sucker 10 according to the present embodiment and a conventional sucker.
Both the conventional nipple and the artificial nipple of the sucker 10 of the present embodiment have a hardness of 22 degrees, and the tightening torque of the cap with respect to the baby bottle is 100N.
Then, only one vent hole is formed in the seat plate portion of the conventional nipple artificial nipple, but in the sucker 10 of the present embodiment, two holes are formed as shown in FIG.
Both of them were sucked at −26.6 kPa based on atmospheric pressure from the center hole of the artificial nipple.
As a result, in this embodiment, as shown in FIG. 6, the negative pressure in the baby bottle was largely eliminated, but in the conventional baby bottle, the negative pressure was difficult to be eliminated.
Further, in the present embodiment, the flow rate of the adjusted milk is increased by eliminating the negative pressure. That is, it was actually verified that the artificial nipple 100 of the present embodiment is an artificial nipple that is easy to use even for infants, which is high in age and has a large intake of adjusted milk.

このように、本実施の形態の哺乳器１０は、負圧が円滑に解消されるので、特に、図４に示す広口径乳首のように、内径が大きく、装着時の歪みが発生しやすいだけでなく、負圧により哺乳器１０内に入り込み易い人工乳首に適用すると、従来生じていた、月齢の高い乳幼児の使用による人工乳首の落ち込みを未然に防ぐことができる。   As described above, the sucker 10 according to the present embodiment eliminates the negative pressure smoothly. In particular, like the wide-bore nipple shown in FIG. In addition, when applied to an artificial nipple that can easily enter the nursing bottle 10 due to negative pressure, it is possible to prevent the artificial nipple from falling due to the use of an infant with a high age, which has occurred in the past.

本発明は、上述の各実施の形態に限定されない。本実施の形態では、センタ孔を円形としたが、これに限らず、Ｙ字状やスリット状としても良い。その場合は、０．５５ｍｍ以上の径のセンタ孔１３０と同等の開口面積を設定する。また、上述の各実施の形態は、相互に組み合わせて構成するようにしてもよい。   The present invention is not limited to the embodiments described above. In this embodiment, the center hole is circular. However, the center hole is not limited to this, and may be Y-shaped or slit-shaped. In that case, an opening area equivalent to the center hole 130 having a diameter of 0.55 mm or more is set. The above-described embodiments may be configured in combination with each other.
