Description

[Detailed explanation of the invention] [Field of industrial application] This invention is designed to adjust the amount of milk sucked according to all sucking and sucking forces of infants, that is, newborns and premature infants, including very small sucking forces. This invention relates to an adjustable nipple for a baby bottle.

[Prior art] Nipples for baby bottles for infants are well known, but in general, milk does not come out too well or milk comes out too much, so it is difficult to adjust the milk amount properly. The current situation is that it is difficult to do so.

The present applicant previously created a nipple for baby bottles in Japanese Patent Publication No. 51-38265 by creating a difference in wall thickness between the sucking opening at the tip of the nipple and the area around the sucking opening into a thin part and a thick part. A cross-shaped cross-cut is made on the thin membrane part, and the thick part acts as a fulcrum, allowing the sucking mouth part to perform a valve action.This allows the milk to be turned into baby food according to the sucking force of the infant. Although they have provided nipples that open to various sizes, they have not specifically discussed the differences in sucking power of infants.

However, in healthy infants, their physical strength improves with age, and at the same time their sucking power gradually increases, so there is no problem in their ability to adapt to feeding bottles, but for sickly infants such as newborns, premature infants, or infants with cleft lip and palate, , their sucking ability is very low, and there are individual differences in ability, so adjusting the amount of milk from the bottle and nipple is very delicate and problematic.

[Problems to be solved by the invention] This invention attempts to solve the above-mentioned problems by changing the tip of the nipple from the conventional hemispherical nipple to a flat shape, and making the center part an arch-shaped thin film part. By making cross cuts in the thin film part, the valve opens wide instantly even in response to the smallest sucking force. In other words, when the same amount of external pressure (sucking force) is applied, the shape of the strained shape at the tip of the nipple is larger than that of a hemispherical nipple, and the nipple opening also opens wider.

[Means for solving the problem] To explain the present invention, as described above, the tip of the nipple of the nipple is formed into a flat shape, and an annular thick wall is formed on the inner surface of the nipple near the center of the tip of the flat nipple. established a department,
An arch-shaped thin film part is provided above the center of the ring of this thick part, and a cross-cut cut is formed in the thin film part, so that the tip of the nipple is easily distorted by external pressure, and the nipple opening is also wide open. This invention relates to a nipple for a baby bottle.

[Function] In this invention, the tip of the nipple is made into a flat thin film, and by making a cross cut in the center, it can be opened immediately by the very small sucking force that can be applied just by touching it, as in the case of a newborn baby. The valve can be opened and closed sensitively to external pressure. This means that if the same external pressure (sucking force) is applied to the original nipple A and the hemispherical nipple, since the leading edge of the original nipple A is flat, the external pressure will appear as distortion at the tip, and the hemispherical nipple will The result is a larger deformation than that of a nipple. For this reason, the opening will inevitably be larger than the breast opening.

The fulcrum of the thick part is located around the thin membrane with cross cuts, so when an infant puts the nipple in their mouth, they put it into their mouth from the tip of the nipple to the swollen body, and squeeze the middle part of the nipple to suck. At the same time as you start to slurp, the crosscut opens, the thick part becomes the fulcrum, and the thin film piece shows a valve effect.

[Example] An embodiment of the present invention will be described according to the drawings.

Figure 1 is a longitudinal sectional view of the nipple A of the present invention, Figure 2 is a bottom view of the nipple A of the present invention, and Figure 3 is an enlarged sectional view of the longitudinal sectional view of the nipple in Figure 1, showing the nipple hole during sucking. It is an explanatory view of the valve open state.

First of all, in FIG. 1, the nipple A according to the present invention has the outermost tip of the nipple, that is, the most proximal part b, formed into a flat shape, and the annular thick part 1 is provided on the inner surface of the nipple near the center of this proximal part b. It consists of a papilla a, a body part 7, and a flange 8, in which cross-cut cuts 4 and 5 are made in an arch-shaped thin film part 3 formed by making a hemispherical small hole 2 in a thick part 1. A rib 7' protrudes below the body 7 and is positioned above the cap. In addition, as shown in the figure, a part of the flange 8 having a taper 8' has a two-stage structure air hole 1.
An air valve 10 is formed by perforating the air valve 1 to form a thin film and making a minus cut, and an annular bottom rib 9 is further provided below the flange 8 to securely connect the bottle and the nipple to protect the air valve 11 from strain. is made slightly longer than the length of the air valve 11, and is molded except for the position of the air valve 11.

In FIG. 2, crosscuts 4 and 5 are formed perpendicularly to the thin film portion 3 at the extreme end b at its center.
administer. FIG. 3 shows an enlarged sectional view of the nipple a, with the thin film portion 3 in the closed state and 3' in the open state during sucking.

[Effect of the invention] Regarding the use of the nipple according to the above invention, the flange 8 of the nipple A of the present invention is placed on top of a bottle containing milk, and the air valve 10 of the nipple A and the bottom rib 9 are placed in the bottle mouth.
When the baby enters, the cap screws together the nipple A and the bottle to form a baby bottle and allows the baby to breastfeed.

In addition, in the case of the nipple A of the present case, the most proximal part b of the nipple a
Since the nipple is flat and the center is composed of the thin film part 3, even a small external pressure causes a large strain in the flat part at the tip of the nipple, and the nipple inevitably opens wider than in a hemispherical nipple. Even with the same external pressure (sucking force), it appears as distortion of the breast hole, so milk can be sucked smoothly even with extremely low sucking force. Therefore, it can be applied to infants with relatively low sucking ability, such as newborns, cleft lip and palate infants, and sickly infants. Of course, it can be adapted to normal children without any problems.
