Abstract

PURPOSE:To allow a sucking to naturally learn the same sucking action as at the time of breast-feeding from the mother's body at the time of breast-feeding with a feeding bottle by providing an internal wall to hang down from a nipple head to a deep part side and forming a milk sucking hole in one part of a diaphragm provided on the hang-down edge of the internal wall. CONSTITUTION:By screwing the female screw of a clamping ring 4 to a male screw 6 of a bottle main body opening 5, a bottle mouth fitting part 9 of a nipple 3 is brought into tightly contact with the bottle main body opening 5, and a setting is completed. Only by holding the nipple 3 of a feeding bottle 1 to be already set in one's mouth and sucking the head, a milk sucking hole 13 is not opened, and a milk in a bottle 2 main body cannot be suck-drunk. Namely, unless a diaphragm 12 existing at the hand-down edge of an internal wall 11 to hand down at the deep part side of a nipple head part 7 is suppress- deformed, the milk sucking hole 13 is not opened. Thus, a sucking learns the fact that milk can be suck-drunk by holding the nipple 3 deeply in his mouth, allowing upper and lower jaws to execute a chewing movement, squeezing the nipple head part 7 with a tongue tip from the deep part to the head side, and simultaneously, allowing a suck-drinking force to be worked.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a nipple for a baby bottle.

[Conventional technology]

Conventional baby bottle nipples are made of highly flexible materials (natural rubber,
Nipples made of plastic, etc.) that are formed in a shape close to the mother's breast and have sucking holes formed at the tip of the nipple are widely used (for example, Japanese Patent Publication No. 38265/1983,
(Refer to Utility Model Publication No. 57-27462, etc.).

[Problem to be solved by the invention]

A conventional baby bottle sucker having a sucking hole formed at the tip of the nipple allows an infant to suck milk from the bottle by simply sucking the tip of the nipple during breastfeeding.

On the other hand, in order for an infant to suckle breast milk directly from the mother's body, the infant must hold the mother's nipple deep in its mouth, up to the areola, and while chewing with its upper and lower jaw, move the tip of its tongue from the areola to the nipple. He is sucking while applying pressure to the side and squeezing.

That is, when breastfeeding directly from the mother's body, it is not possible to suck enough milk (breast milk) just by sucking the tips of the mother's nipples (nipples).

Breastfeeding has recently come into the spotlight, but for several days immediately after birth, infants are fed formula milk using a bottle, which is produced by breast milk. There are times when you have no choice but to do so. In such cases, bottle-feeding does not require as many complex linked movements of masticatory movements of the upper and lower jaws and squeezing movements of the tip of the tongue as compared to direct breastfeeding from the mother's body. It has been pointed out that as a result, infants tend to make less effort to suck, which may hinder a smooth transition to breastfeeding. It has also been reported that by subjecting infants to training, it naturally contributes to the development of the cerebrum.

The present invention has been proposed in view of the above points, and its purpose is to provide a nipple for a baby bottle that can induce sucking effort more similar to the state of breastfeeding directly from the mother's body. It is something.

[Means to solve the problem]

In order to achieve the above object, one aspect of the present invention is to provide an inner wall that has an opening at the tip and hangs down toward the back from the tip of the nipple,
A diaphragm is provided at the hanging end of this inner wall, and a sucking hole is formed in a part of this diaphragm.

Another aspect of the present invention is to provide an inner wall extending from the inner surface on the bottle spout fitting side to the nipple tip side in the deep part of the nipple tip having an opening at the tip, and to provide a diaphragm at the extended end of this inner wall. A sucking hole is formed in a part of the diaphragm.

[Function] The sucking hole opens when the diaphragm is pressed, and closes when the pressure is released. This diaphragm is located deeper than the tip of the nipple, so the sucking hole opens when the infant holds the nipple deeply in its mouth and presses the diaphragm with the tip of its tongue while chewing the nipple up and down. . As a result, when breastfeeding with a baby bottle, it is possible for the infant to naturally learn the same sucking motion as when breastfeeding from the mother's body.

〔Example〕

FIG. 1 is a longitudinal sectional side view of a nipple for a baby bottle showing one embodiment of the present invention, and the baby bottle (1) schematically includes a bottle body (2), a nipple (3), and a nipple. is composed of a ring (4).

The bottle body (2) is made of transparent plastic and has a roughly cylindrical shape. The bottle body (2) has an upper opening (
The opening (5) is completely closed except for the opening (5), which has a circular shape with a slightly smaller diameter. Opening (5)
A male thread (6) is provided on the outer periphery of. A scale (not shown) is provided on the side of the bottle body (2) to measure the amount of milk sucked by the infant.

The nipple (3) is made of transparent, flexible and elastic material (natural rubber, plastic, etc.) that is harmless to infants and can be sterilized by boiling. The nipple (3) is sized to fit the infant's mouth, and its shape roughly consists of an egg-shaped nipple tip (7), an inverted funnel-shaped middle part (8), and a bottle opening fitting part ( 9), which are integrally molded.

The nipple tip (7) is formed with a substantially -shaped wall thickness, and has a small diameter opening (10) at the central tip. This small diameter opening (
10) is circular in the illustrated example, but may have another shape.

At the back of the nipple tip (7), there is provided an inner wall (11) that hangs integrally from the small-diameter opening (10) toward the back, and a diaphragm (12) is integrally formed on the hanging end of this inner wall (11). do.

The inner wall (11) is shaped like a diaphragm (1) by the infant's sucking force.
The portion 2) is formed so as not to be exposed from the small diameter opening (10). The diaphragm (12) is formed to partition the inside of the nipple (3), and has one or more sucking holes (13) formed in a part thereof, for example, in the center or the periphery. However, the figures and planes show a case where one sucking hole (13) is formed in the center of the diaphragm (12).

The formation position of the diaphragm (12) is preferably near the areola-equivalent position in the mother's breast, and in terms of the position inside the nipple (3), it is at the boundary between the breast d tip (7) and the inverted funnel-shaped middle part (8). It is preferable to place it near the tip of the nipple (
7) or in the opposite direction.

As shown in Fig. 1, the diaphragm (12) may be a flat membrane parallel to the plane perpendicular to the center line #i of the nipple (3), or may have a convex spherical surface or a concave spherical shape on the tip side. good.

The thickness of the diaphragm (12) should be such that it can be deformed by the normal chewing force of the infant's upper and lower jaws.

The sucking hole (13) formed in the diaphragm (12) is formed by a cut, and this cut is either a ■-shaped single cut, an X-shaped cross cut, or a Y-shaped triple cut. Form.

In the case where the sucking hole (13) is cut-shaped, the sucking hole (13)
) The diaphragm (12) at the formation position is preferably formed thinner than other parts.For example, as shown in FIG. Hole (
13), the point of change in wall thickness between the central part and the peripheral part becomes a fulcrum for the opening and closing operation of the notched hole edge, allowing smooth opening and closing operation, and improving the function of the check valve. can have.

The inverted funnel-shaped intermediate portion (8) is formed continuously from the base of the nipple tip (7) and continues to the bottle mouth fitting portion (9).

The bottle mouth fitting part (9) fits the bottle body opening (5),
A flange (14) is provided which acts to seal the baby bottle (1) by receiving the pressing force of the ring (4).

Tapered portions (15) are provided above and below the outermost edge of the flange (14) to help ensure more complete contact between the nipple (3) and the bottle body (2). Also, tightening is done with a ring (
4) and the nipple (3) are fitted in a ring shape in the boundary area between the inverted funnel-shaped middle part (8) and the bottle opening fitting part (9). The flange (14) is provided with one air valve (17) inside a circumferential tapered portion (15) in direct contact with the bottle body opening (5). A plurality of air valves (17) can also be provided.

The air valve (17) has a two-stage structure in which the outside diameter is larger than the inside diameter, and a cup-shaped protrusion inside the small hole (18). 17) has a check valve structure consisting of a thin film portion (19) that is single-cut or cross-cut in an X-shape in the axial direction.

In order to protect the air valve thin film part (19), the bottom of the flange (14) has a part of the peripheral taper (
15) is provided with a ring-shaped lip (20) slightly higher than the height of the protrusion of the air valve thin film portion (19).

The tightening ring (4) is made of plastic with some elasticity, and is designed so that the nipple (3) can be removably fitted into the opening (5) of the bottle body at its bottle mouth fitting part (9). A circular notch is provided in the center of the top lid with a size that fits the bottle spout fitting part (9), and a female thread that is threadedly connected to the male thread (6) of the bottle body opening (5) is tightened. are provided on the inner surface of the side part of the ring (4).

The above is the configuration of the baby bottle according to one embodiment of the present invention,
Next, we will explain how to use it.

To tighten, loosen the screw by operating the ring (4), and to tighten, remove the ring (4) and nipple (3) from the bottle body (2). Milk is poured into the bottle body (2) through the bottle body opening (5) in an appropriate mold. Set the nipple fitting part (9) on the tightening ring (4). To tighten, screw the female thread of the ring (4) onto the male thread (6) of the bottle body opening (5), and then attach the bottle spout fitting part (9) of the 6th nipple (3) to the bottle body opening (5). the set is completed. If you just hold the nipple (3) of the set baby bottle (1) in your mouth and suck the tip, the sucking hole (13) will not open and the milk in the bottle body (2) will be sucked. I can't. That is, the diaphragm (12) at the hanging end of the inner wall (11) that hangs down toward the back of the nipple tip (7).
The sucking hole (13) will not open unless it is compressed and deformed. This allows the infant to deeply hold the nipple (3) in his/her mouth,
Chew the upper and lower jaws and touch the tip of the nipple (7) with the tip of your tongue.
The baby will learn that milk can be sucked by applying sucking force while squeezing from the back to the tip. Such a sucking motion is more similar to the sucking motion when breastfeeding directly from the mother's body. During the sucking operation, the opening degree and the amount of milk flowing out of the sucking hole (13) are naturally adjusted according to the sucking force of the infant and the compressive force of the inner wall (11) and the diaphragm (12), And during this time, the air valve (1
The air valve (17) opens and closes to replenish air into the bottle body (2), allowing the infant to continue and smoothly breastfeed. When you stop sucking, it closes completely to prevent milk from flowing out.

In addition, the sucking hole (13) formed in a part of the diaphragm (12) is
In addition to cuts, single or multiple small holes may be used.

Next, FIG. 3 shows another embodiment of the present invention, in which the inner wall (11) is extended from the inner surface on the bottle mouth fitting part (9) side, and the A diaphragm (12) is provided at the end, and a sucking hole (13) is formed in a part of this diaphragm (12). The other configurations are the same as those in FIG.

Further, the usage is also the same as that in FIG. 1, so a description thereof will be omitted.

〔Effect of the invention〕

According to the present invention, when breastfeeding with a baby bottle, the action of holding the nipple deeply in the mouth, making masticatory movements of the upper and lower jaws, and applying sucking force while squeezing the tip of the nipple from the back to the tip side with the tip of the tongue, that is, It is estimated that this method is more similar to direct breastfeeding from the mother, allowing for a smooth transition to breastfeeding for newborns and contributing to cerebral development.

In addition, the structure is simple because the diaphragm is simply provided through the inner wall that hangs down to the back of the nipple tip, or the diaphragm is provided through the inner wall that extends from the inner surface on the side of the bottle spout fitting. Not only is it easy to manufacture, it is also easy to clean, and residual milk residue and clogging can be easily removed by cleaning, and it does not interfere with boiling sterilization.
