Abstract

PURPOSE:To obtain a nursing nipple permitting an infant to efficiently drink milk by the movement of a tongue, by a method wherein a nipple part is formed into such a slightly flat and almost oval cross-sectional shape, that the part near to the leading end of one of flat parts and the central part of the other flat part are thick and the region from both side parts of the nipple part to the head part thereof is thin, and an emitting port is formed to the leading end part of the nipple part. CONSTITUTION:A nipple part 4 is inserted in the mouth of an infant so that one flat part 5 of said nipple part is turned to the upper jaw of the infant and the other flat part 6 thereof is turned to the tongue of the infant. The infant receives the nipple part 4 in the oral cavity thereof and the body part 3 of a nipple is supported by the upper and lower lips 8 and gum 9 of the infant, and the nipple part 4 is grasped between the tongue 10 and upper jaw of the infant. The infant sucks the under surface of the nipple part 4 toward the leading end thereof while pushes up the nipple part 4 toward the upper jaw 11 by the tongue 10. At this time, since the central part of the flat part 6 of the nipple part 4 is formed thickly, it is prevented that only the part to which the tongue is applied is locally depressed and the whole of the flat part 6 is pushed up toward the opposed flat part 5 and milk is emitted from an emitting orifice 7. since the flat part 5 is flat and the part near to the leading end thereof is thick, said flat part 5 is easily deformed along the upper jaw 11 of the infant and the nipple is stable in the oral cavity.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a nursing nipple that is attached to a baby bottle and is used to feed an infant.

Conventional Technique f41 As shown in Japanese Utility Model Publication No. 56-8677, conventionally used nursing nipples have a generally hemispherical body on the upper part of the flange that is connected to the opening of the baby bottle. A nipple is formed in the upper central part of the body, and the upper end of the cylinder is closed in a substantially hemispherical shape, and a suitable discharge port is bored in the center of the tip of the nipple.

Also known as a special nipple is one in which one side of the nipple is flat and the flat part is thicker than the other parts, as shown in Japanese Patent Laid-Open No. 60-182949.

Problems to be Solved by the Invention By the way, when an infant is normally fed, when the nipple is inserted into the mouth, the nipple of the nipple is captured by the upper and lower gums and the tip of the tongue, and the upper and lower lips are attached to the base of the nipple. Close it to enclose it. The tip of the tongue presses the papilla of the nipple from below and handles the nipple from the base toward the tip, creating negative pressure in the oral cavity and causing milk to flow into the oral cavity.

Therefore, the structure of the nipple is preferably one that allows milk to flow efficiently into the oral cavity through this behavior.

However, although the general nipple mentioned above is suitable for sucking out milk by suction, it is not necessarily suitable for squeezing out milk with the tongue.In other words, the nipple is cylindrical. Because of this, the position of the nipple in the upper jaw is not stable, and the material of the nipple is usually too flexible, so when you press it with your tongue, only the part that you pressed with the tongue becomes depressed, making it impossible to squeeze out a sufficient amount of milk.

In particular, in the case of a discharge hole having a circular needle hole shape, milk is discharged only by suction, and cannot be discharged by tongue movement, which does not correspond to the movement of an infant when refilling. Also, “cross” shape and “Y”
For those with letter-shaped discharge holes, the discharge amount varies depending on the angle of the nipple in the oral cavity, and depending on the angle, milk may not be discharged sufficiently.

The teat disclosed in Japanese Patent Application Laid-open No. 60-182949 was invented as a nipple for infants with cleft lip and jaw, and is excellent in that the flat part stably contacts the upper jaw of the cleft area. The parts other than the flat part are thin and flexible, and the disadvantage that a sufficient amount of milk cannot be discharged when pressed with the tongue has not been solved.

The present invention has been made in view of the above circumstances, and is a novel feeding method that allows milk to be discharged by suction in the same manner as before, and also enables milk to be efficiently squeezed out and drunk by the movement of the infant's tongue. The purpose is to provide a nipple for use.

As a means of solving the problem, the present invention provides a method in which the papilla has a flat, approximately elliptical cross section, and the part near the tip of one flat part and the central part of the other flat part are thickened. It is characterized by having a thin wall extending from both sides of the nipple to the tip, and having a discharge port formed at the tip.

Another invention of the present application is that in the nursing nipple, the discharge port is a "-"-shaped slit extending in the short diameter direction of the nipple, and the discharge port is located at the tip of the nipple. The nipple is formed closer to the center or closer to the other flat part, and the nipple is provided protruding from the center of the upper surface of the torso, and the nipple is formed at least in the flat part of the torso. The outer surface of the body and the upper surface of the body. is characterized by forming seven right-angled steps.

The drawing shows a nursing nipple of the present invention, which is made of a soft elastic material such as rubber or polyurethane. A flange portion 1 is formed at the lower end thereof, and an air valve 2 is provided in a part of the flange portion 1. By placing this flange portion 1 on the periphery of the opening of the baby bottle and tightening it with a screw, the nursing nipple is attached to the baby bottle and the air valve 2 opens, allowing outside air to pass through the inside of the baby bottle. Shinuru.

A body portion 3 is bulged from the upper part of the flange portion 1. The body 3 has a substantially hemispherical or bell-shaped shape, and a nipple 4 is protruded from the center of the top.

The inner surface of the papilla 4 has a substantially oval cross section, and flat portions 5 and 6 are formed facing each other. and one flat part 5
The part near the tip is thick, and the thickness gradually becomes thinner from there downward. In addition, the other flat portion 6 has a thick wall at the center, and the wall thickness gradually decreases upward and downward from there. Further, the top and both sides of the nipple 4 are formed thin.

The inner circumferential surface of the teat head 4 has a cylindrical shape with an oval cross section as described above, and the changes in the thickness of the teat head 4 are all caused by changes in the shape of the outer circumferential surface. Therefore, the external shape of the papilla 4 is that its base is slightly constricted,
A portion near the tip of the one flat portion 5 and a central portion of the other flat portion 6 have a bulged shape.

At the base of the nipple 4, the upper surface of the body 3 and the outer surface of the flat portion 5.6 form a step at right angles.

Further, a discharge lower formed of a "-"-shaped slit extending in the short diameter direction of the teat head 4 is bored at the top of the teat head 4. The discharge lower is bored at a position closer to the center of the tip of the nipple 4 and the other flat portion 6 of the nipple.

Operation In the present invention, as shown in FIG. 4, the device is inserted into the infant's mouth with the negative flat portion 5 facing the baby's upper jaw and the other flat portion 6 facing the tongue.

The infant accepts the papilla 4 into the oral cavity, and the upper and lower @8 and the gums 9
supports the trunk 3 and holds the papilla 4 between the tongue 10 and the upper jaw 11. This state is shown by the solid line in FIG.

Here, the infant pushes up the nipple 4 toward the upper jaw 11 with the tongue 10 while handling the lower surface of the nipple 4 toward the tip of the nipple 4 and sucking it. At this time, since the central part of the flat part 6 of the papilla 4 is formed within the thickness, only the part where the tongue 10 hits is not locally depressed, and the entire flat part 6 is formed in the opposite flat part 5. They are pushed up to approach each other, and milk is discharged from the discharge lower.

Further, since the flat portion 5 is flat and the portion near the tip is thick, it easily follows the shape of the baby's upper jaw 11 and is stable in the oral cavity.

Effects of the Invention According to the present invention, by pushing up the flat part 6 with the tongue 10, the flat part 6 as a whole is pushed up so as to approach the flat part 5, so that the space inside the papilla 4 is efficiently reduced. At the same time, the discharge lower opens easily, milk is discharged efficiently, and breastfeeding is extremely easy.

Normally, the outlet of the nipple forms a "cross" or "Y" shaped incision at the tip of the nipple, but in the present invention, the posture of the nipple 4 in the oral cavity is stabilized. Therefore, if there is a vertical slit in the oral cavity, the slit can be easily and sufficiently opened by pressing the papilla 4 against the upper jaw 11 with the tongue 10. Therefore, in the second invention, there is only a J-shaped slit extending in the short diameter direction.Therefore, in this invention, the discharge lower is less likely to open inadvertently and spill milk, and the discharge lower Excellent durability.

Further, according to the third invention, since the discharge lower is formed at a position close to the flat portion 6, the milk is once discharged onto the tongue 10, flows on the tongue 10, and is poured down. Therefore, the milk does not directly squirt into the back of the throat, which has the effect of preventing the infant from drying out.

Furthermore, in the present invention, since the nipple 4 is inserted into the oral cavity and manipulated with the tongue to discharge milk, it is not preferable to insert the 7L neck too deeply into the infant's mouth.

According to the fourth invention, since a step is formed between the flat parts 5, 6 of the nipple 4 and the trunk 3, only the nipple 4 can be placed in the oral cavity regardless of how the infant holds the nipple. It is inserted into the body and can be held in the optimum condition at all times.
