Description

[Detailed Description of the Invention] The present invention particularly relates to a nursing bottle for use with a direct nipple.

A nursing bottle that uses a direct-attached nipple has a nipple that fits well into the mouth of the baby bottle so that it does not come off even if the baby holds it in his/her mouth and pulls on it during breastfeeding, and also prevents the nipple from falling out of the mouth of the baby bottle when breastfeeding. Various improvements have been made in the past to ensure that the introduction of air is carried out appropriately in response to the sucking of milk.

The present invention was also made in view of the above, and includes a baby bottle with an annular bead formed at the upper end of the opening, and a nipple with an upper flange extending laterally and continuing from the periphery of the enlarged lower end of the nipple body.
an upper cylinder extending downward from its outer periphery; a lower flange extending laterally from its lower edge; a lower cylinder extending laterally from its outer periphery;
A knob is formed from a part of the lower edge, and then an annular groove is formed on the inner surface of the lower cylinder between it and the lower flange, and an annular protrusion is formed on the lower surface of the lower flange with a gap provided in a part of the knob. In addition, the annular groove and a part of the inner surface of the lower cylinder have vertical grooves for introducing air, which ensures that the bottle can fit securely into the mouth of the baby bottle, and can also be inserted into the bottle during breastfeeding. This allows air to be introduced appropriately in response to sucking of milk.

The present invention will be described below with reference to an embodiment shown in the drawings.A baby bottle 1 is a so-called wide-mouth bottle with the same diameter, and the bottle mouth edge forms an annular bead 3 with a narrow circumferential groove 2 formed below.

The nipple 4 is made of natural rubber or special synthetic resin, and the nipple 5, neck 6, and bulge 7 form a nipple body 8, and the top surface 9 of the soybean nipple is flat and thin. , a suction hole 10 is formed in its center.

First, an upper flange 11 is formed in this nipple body 8 in a continuous manner with the lower end periphery of the swollen portion 7, and an upper cylinder 12 extending downward from the outer periphery of the flange 11 is formed in an arc shape.
A lower flange 13 is formed from the lower edge, a lower cylinder 14 is formed downward from the outer peripheral edge, a knob 15 is formed from a part of the lower edge to adjust the outer shape, and then the lower cylinder 14 is formed.
An annular groove 16 that fits and presses into contact with the annular bead 3 of the baby bottle 1 is formed at the upper part of the inner surface of the baby bottle 1 between the bottom flange 13 and an annular flange 17 that comes into pressure contact with the bottom surface of the baby bottle mouth on the bottom surface of the bottom flange 13. In the drawing, gaps 18 are formed at three equally spaced places in a part of the cylinder, and two vertical strips for air introduction are formed in the annular groove [6] and a part of the inner surface of the lower cylinder 14, that is, in the part of the knob 15. A groove 19 and a vertical groove 20 are formed, and a slight convex portion 21, 22 with an arcuate inner surface is formed between each groove.

In the above embodiment, when the baby bottle 1 is filled with milk and the nipple 4 is attached to the bottle mouth, the state shown in FIG. 1 is obtained.

That is, the annular groove 16 of the teat 4 fits into the annular bead 3, the lower cylinder 14 fits inside it and is attached in a press-contact state, and the annular protrusion 17 also comes into press-contact with the bottle mouth end surface. A convex portion 21 formed on the annular groove 16 and the inner surface of the lower cylinder 14
and the convex portion 21 forms an air introduction path between the longitudinal groove 19 and the annular ridge 17 on the lower surface of the lower flange 13 without losing the vertical groove 19, 20 even when the restoring force of the nipple material is applied;
When the pressure is removed in the baby bottle by sucking milk from the sucking hole 10 of the teat 5, air is introduced and enters through the gap 18 formed in the annular ridge 17, and the milk can be sucked without resistance.

In the above embodiment, the knob 15 is located at the annular protrusion 17.
It is more effective to form the gap between two of the three gaps 18 formed in the above.

That is, when breastfeeding, if the knob 15 is placed upward, two of the three gaps can be used for introducing air.

However, in this case, if the infant's sucking power is low and the sucking power increases as the infant's growth progresses, air should be introduced in accordance with the sucking power no matter what condition the infant is breastfeeding in. Can be done.

The present invention provides a direct attachment nipple as described above, in which a baby bottle is formed with an annular bead at the upper end of the opening, an annular groove is formed on the inner surface of the nipple to fit into the annular bead, and the annular groove Two longitudinal grooves are formed on a part of the inner surface of the lower cylinder, and a slight convex portion is formed between the longitudinal grooves, and an annular ridge is formed on the lower surface of the lower flange, and three gaps are formed between the two longitudinal grooves. When the nipple of a baby bottle is attached, the space between the lower cylinder, the annular groove and the outer peripheral surface of the bottle mouth, and the inner side of the annular protrusion a
A ventilation path is formed between the bottle and the end surface of the bottle mouth, and communicates with the gap formed in the annular ridge, so that air is introduced into the bottle in response to sucking of milk, and the bottle is kept in good condition. It is possible to breastfeed, and since three gaps are formed at regular intervals in the annular protrusion, it has various effects such as being able to breastfeed from any position under the same conditions.
