Description

[Detailed Description of the Invention] The present invention relates to a nipple for a nursing bottle, and an object of the present invention is to provide a nipple that has good suction during use and can appropriately supply milk.

Originally, the purpose of a nursing bottle was to fully elicit the suckling movement of infants by holding the nipple tightly in their mouth and sucking out milk with the force of their jaws and tongue.

To achieve this, it is necessary to make the tip of the nipple, that is, the nipple, into a shape that is easy to suck without deforming it, and to ensure that the amount of milk that comes out is stable.

This invention was made in consideration of the above points, and the thickness of the nipple is made thicker at the body and thinner at the neck, and the nipple is slightly thicker than the neck, and the nipple is made thinner on the inner surface toward the center. The outer shape is formed so that the vertical cross section is approximately horizontally circular, and the top surface is formed with a through hole that is continuous with three cuts and has a through hole that does not leak liquid at the end of each cut. By doing so, the above purpose can be achieved.

The embodiment of the present invention shown in the drawings will be described below. The nipple 1 is made of natural rubber or special artificial rubber, and its wall thickness is thick at the body 2 and gradually becomes thinner toward the neck 3. It is formed slightly thicker than 3.

A circumferential groove 5 is formed in the lower part of the body part 2 for fitting into the upper surface through-hole edge of the tightening cap for attaching the nipple to the baby bottle, and a flange 6 of approximately the same thickness is formed at the lower end of the circumferential groove 5. .

The papilla 4 has an inner surface that is gradually thinner toward the center to form a concave portion, an outer shape that is approximately horizontally circular in longitudinal section, and a top surface that is slightly flat. Continuing with the cut, a through hole 7 is formed at each cut end, which is a circular through hole that does not leak liquid.

On the upper surface of the collar 6, an annular groove 8 is formed continuously on the side wall of the circumferential groove 5.
is formed, and a projecting edge 9 is formed in an annular shape on the outer circumferential raising surface, and a horizontally elongated rectangle extending from the inner edge of the annular groove 8 to the inner edge of the bottle mouth end surface 11 of the baby bottle 10 is formed on the lower surface. A concavity 12 in the shape is formed, and the ends are shallower than the concavity and widen toward the outside in a small mound continuous with the concavity, and the center of the top is low and is raised with a gentle slope toward both ends. A groove 13 that is narrow at the center and widens toward both ends is formed in the radial direction to form a ventilation path between the bottle and the end face 11 of the bottle mouth.

Then, the recess 12 has a ventilation hole 1 communicating with the annular groove 8.
3 is formed.

Further, the tightening cap 14 that holds the nipple 1 and screws it onto the bottle mouth is molded from hard synthetic resin, and the circular hole 15 for attaching the nipple that loosely holds the nipple in the circumferential groove 5 in the center of the upper wall surface is made of hard synthetic resin. A downward annular protrusion 16 that fits into the annular groove 8 is formed, and when an infant holds the nipple in its mouth and pulls on it, it catches and prevents the nipple from falling out.

Further, an annular projection 17 is formed on the lower surface for pressing the collar 6 of the nipple 1 against the bottle mouth end surface 11.

The nipple 1 is attached to the baby bottle 10 with a tightening cap 14, as shown in FIG.

When the baby bottle 10 is filled with milk and the baby is fed with the tightening cap 14 tightened, the pressure inside the baby bottle 10 is reduced due to sucking, and the inside of the bottle is sucked from the vent hole 13a through the gap between the side wall of the circumferential groove 5 and the inner hole 15. Air is permeated through the body and normal suction and drinking occur.

When the infant grows up and has strong sucking power and the amount of milk flowing out is insufficient, the tightening cap 14 is loosened.

In such a case, the amount of milk flowing out is increased by ventilating through the gap formed by the threaded portion of the baby bottle 10 and the tightening cap 14 through the ventilation passage formed by the bottle mouth end face 11 and the groove 13b.

In this case, the amount of milk flowing out is adjusted by the tightness of the tightening cap 14.

On the other hand, in the nipple 1, the nipple 4 has an approximately horizontal cross-circular shape in the longitudinal section, so it is easy to suck, and it is difficult to deform, resulting in a stable flow rate. The nipple 4 is formed slightly thicker than the neck 3, so the lips and tongue are in close contact with each other, and the through hole 7 is three-cut, and each cut end is connected with a through hole that does not leak, so it can be opened. The opening is extremely smooth, and the closer you get to the center of the cut, the thinner the wall thickness is, so it gradually becomes larger and does not open suddenly and cause suffocation.

Of course, there will be no leakage from the through hole 7 even if the milk is filled with milk and falls over.

As mentioned above, the present invention provides a nipple that has extremely good suction during use, provides a stable amount of milk, and allows breastfeeding in a state similar to that of a mother's breasts. It's something you get.
