Description

Infant Pacifier For anti-reflux}

The present invention relates to a baby nipple, and in particular, a backflow prevention device used to prevent backflow of liquid due to the difference in temperature and pressure between the inside and outside of the container when the nipple of a container containing liquid such as milk or beverage is locked with a connecting member. It's about infant nipples.

Generally, infants consume formula through a bottle. A baby bottle is a container that contains a liquid such as milk or beverage, a nipple that is coupled to the top of the container and pressurized to consume the milk or beverage contained in the container, and a nipple that is coupled to the top of the container in a fastened state to seal the container. It is composed of connecting members. At this time, the shape of the nipple may be composed of a nipple-shaped nipple with a feeding hole formed at the end, and a straw-shaped nipple with a penetration passage of the same diameter at both the top and bottom in the form of a cylindrical straw.

When an infant sucks the liquid inside the bottle through the nipple while the bottle is tilted, the inner bottom of the bottle becomes a vacuum state. A ventilation hole is provided on one side of the nipple to maintain this vacuum space at atmospheric pressure. This allows the air outside the container to flow into the inside of the container, which is in a vacuum state.

A nipple provided with ventilation holes in this way allows infants to easily consume milk and beverages in the container without forcibly sucking them in, thereby reducing the incidence of otitis media that may occur in infants when consuming milk or beverages.

As a related prior art, Korea Patent No. 10-2182367 (November 18, 2020) discloses an aeration device for baby bottles.

As shown in FIG. 4, in the prior art, an auxiliary pressure adjustment hole 331 is formed on the inside of a cut groove 351 that is concave from the outside to the inside on one side, and the auxiliary pressure adjustment hole 331 ), an auxiliary pressure control film 332 is formed with a linearly cut auxiliary opening and closing hole 333 in the center. Through the configuration of the auxiliary pressure control membrane 332, a ventilation hole is provided so that the air outside the container flows into the inside of the container in a vacuum state.

In addition, in baby bottles, the temperature inside the container becomes higher than the temperature outside the container due to the high temperature of the milk and beverage contained within the container, thereby increasing the internal air pressure. This causes the milk and beverage to flow into the feeding hole or penetration of the nipple due to the difference in air pressure inside and outside the container. A phenomenon of backflow to the outside occurs.

To solve this problem, a separate backflow prevention member is installed between the container and the nipple to prevent backflow of liquid due to the difference in air pressure inside and outside the container.

As a related prior art, Korea Patent No. 10-1897663 (2018.09.05.) discloses a backflow prevention member with a backflow prevention function.

As shown in FIGS. 3 and 4, the prior art is to place a backflow preventer (20) between the baby bottle body (10) and the nipple (30) separately from the nipple (30), and to use a nipple clamp (40). It is configured to be inserted through. The configuration of the backflow prevention body 20 is configured to prevent the backflow of liquid to the outside through the nipple's feeding hole or through passage due to the difference in air pressure between the inside and outside of the container.

However, as in the prior art, since a separate backflow prevention member is constructed to prevent backflow phenomenon, there is a problem in that additional manufacturing costs for the backflow prevention member are required.

In addition, since baby bottles are made up of multiple parts, it is inconvenient to separate and assemble the multiple parts each time the baby bottle is washed. Adding a separate backflow prevention member causes this inconvenience even more. There is a problem that has consequences. In fact, families with infants usually use about 4 to 6 baby bottles together. If the number of parts that make up a baby bottle is large, it becomes more cumbersome to separate and assemble the bottle for cleaning, and a large number of small-sized bottles are also used. There is a problem in that parts are easily lost.
