Artificial nipple for a nursing bottle

Abstract

The invention aims to provide an artificial nipple for a nursing bottle which permits close fitting of the nipple to the sucking fossa of an infant while avoiding deformation of the nipple while providing a form that is similar to a human nipple, and which can prevent the upper and lower sides of the nipple from contacting each other during peristalsis-like movements. In view of this, the present invention provides an artificial nipple for a nursing bottle having: a nipple top part having at its tip a dispensing hole for dispensing a liquid drink; and an artificial nipple body which is continuous to the nipple top part, and whose diameter and wall thickness are greater than those of the nipple top part. The artificial nipple is made of a flexible material. The nipple top part has a rib, which prevents contact between an upper side and a lower side of the nipple top part when the nipple top part is compressed flat, at a portion where gums of an infant touch when an upper lip of the infant is in contact with the artificial nipple body or at an internal surface in the vicinity of the portion.

Description

technical field [0001] The invention relates to an artificial nipple for a feeding bottle used for breastfeeding infants. Background technique [0002] When breastfeeding with the sucking movement of the infant, the nipple is placed in the breastfeeding socket (depression) of the upper jaw of the infant, and the nipple is squeezed from the root to the tip by using the peristaltic movement of the infant's tongue Yes, the above-mentioned breast-feeding action can be performed by making the nipple close to the breast-feeding socket of the infant's palate. [0003] In order to facilitate the sucking action of infants, an artificial teat for nursing bottles has been proposed that allows the nipple to smoothly enter the nursing nest by making the nipple more off-center (Japanese Patent Publication No. 2000-288). [0004] However, this artificial pacifier has the following problems: since its shape is different from human nipples, it will cause discomfort to infants; The upper si...

AI Technical Summary

Problems solved by technology

[0004] However, this artificial pacifier has the following problems: since its shape is different from human nipples, it will cause discomfort to infants; The upper side and the lower side of the nipple are pressed together to flatten the nipple, and the inside of the nipple becomes vacuum and breastfeeding cannot be performed.

The above-mentioned artificial teat can be formed into a shape similar to a human nipple, and if it is made of elastic material, it can allow the nipple to enter the lactation socket, but there is a problem that the shape of the nipple is squashed and prevents smooth peristaltic movement , and there is a problem that it is difficult to make the nipple close to the nursing nest of the infant, and since the valve port of the check valve is formed in a slit shape, there is a problem that breastfeeding cannot be performed when the valve port is clogged and the inside of the nipple is in a vacuum state.
