BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baby bottle for infants, and more particularly to a baby bottle which is already filled with sterile purified water for dissolving milk.

[0002]

2. Description of the Related Art A conventional baby feeding apparatus comprises a container body made of polycarbonate, an artificial nipple made of synthetic rubber, a ring-shaped resin-made stopper, and a hood. The artificial nipple is joined to the open end surface of the container body. A screw portion is formed in the container opening, and a ring-shaped stopper is screwed and attached. Then, the peripheral edge of the artificial nipple is positioned and sandwiched between the stopper and the opening end surface, whereby the peripheral edge of the artificial nipple is liquid-tightly adhered to the opening end surface. In addition, a communication hole for preventing collapse of the artificial nipple is formed in a peripheral portion of the artificial nipple.
When using such a feeding device, first, hot water after boiling is put in the container body, and then milk is melted and cooled to a predetermined temperature, and then lactation is started. In addition, since the feeding hole of the artificial nipple needs to be changed according to the age of the infant, artificial nipples having different diameters and shapes of the feeding hole are available. In addition, various types of milk are also available due to the relationship between metabolic abnormalities and immunological abnormalities (such as atopy) in infants. Further, even when the milk is cooled or sucked by the infant's nipple during feeding, and the nipple is crushed due to negative pressure in the container body, air is supplied into the container from the vent hole. I am trying. Then, after breastfeeding, the conventional feeding device is disassembled into respective members, washed and sterilized by boiling, dried, and then used again.

[0003]

By the way, in the conventional nursing device, it takes time to clean and reuse each time it is used. In addition, the conventional baby feeding machine does not cause a problem in preparing milk in a household having a tap and a boiling facility, but has a problem in use in an emergency or in the field. With the recent widespread use of inexpensive resin elastomers and the like, it has become possible to provide inexpensive artificial nipples. Therefore, portable disposable baby bottles and the like have been proposed, and the above problems are being solved. . However, conventional feeding devices require an errand from milk powder and tap water. That is, tap water is boiled once, milk powder is dissolved in hot water at about 70 ° C, and this is brought to around 38 ° C with a cooling device or the like, and then breast feeding is performed, which is very troublesome. In the case of disposable baby feeding devices, milk prepared in advance is packed in a container, and the human skin is warmed outdoors by using a disposable warmer and the like. However, even in such a case, the preparation of milk requires the same labor as that of a conventional feeding device. Commercially available formula milk may be used, but there are few types of commercially available formula milk for adults, and in many cases the milk is left in a place other than the refrigerator so that it cannot withstand long-term storage. In fact, even if the milk is sterilized and filled in the feeding container, it is not completely sterilized, and therefore, it cannot avoid the deterioration due to the temperature after one day. Furthermore, recently, infants with hypersensitivity such as atopy may react sensitively to certain indigenous bacteria and other proteins in tap water. In such a case, tap water etc. should be prepared in the preparation of milk. The use of causes problems.

Therefore, an object of the present invention is to provide a convenient and convenient disposable baby container, which can be easily adjusted to a proper temperature by a simple heating means without the need to cool the milk at the time of milk preparation and the allergic abnormality can be prevented as much as possible. The object of the present invention is to provide a feeding container capable of preparing the prepared milk.

[0005]

According to the present invention, a resin container main body in which an artificial nipple is liquid-tightly joined to an opening during use, water filled in the container main body, and a side wall of the opening of the container main body. A ring-shaped stopper that is attached by engaging the formed engaging portion and holds the artificial nipple in the opening with the peripheral edge of the artificial nipple sandwiched between the ring-shaped stopper and the opening of the container body. And a sealing material which is liquid-tight and can be opened at the time of use. A water-repellent gas-permeable film is provided at the opening of the ring-shaped stopper, and the filling water is steam-sterilized. The above-mentioned object is achieved by providing a nursing device characterized in that the adhesive sealing strength of the above-mentioned sealing member can withstand the steam sterilization.

According to the present invention, the gas permeable membrane is attached to the opening of the ring-shaped stopper, and the lid is replaceable with the artificial nipple. According to the feeding device of the present invention, the gas-permeable film is peelably coated on the opening of the ring-shaped stopper.

[0007]

In the above-mentioned feeding container, the resin container body is 10
High-pressure steam sterilization at 0 ° C. or higher, particularly 105 ° C. to 130 ° C. is possible, and the seal member of the connection opening of the artificial nipple is also welded to the opening and has a seal strength capable of withstanding high-pressure steam sterilization. The purified water filled in the body is sterilized by steam sterilization. Even if such sterile purified water is stored in the container for a long period of time, no water rot or bacterial growth is observed. Therefore, it is not necessary to boil the filled purified water when using the feeding container, and it is safe to dissolve the milk powder at room temperature. For this reason, it is possible to quickly prepare milk without the need for operations such as so-called hot water adjustment when adjusting milk, and it is possible to easily warm the filling water in the container to the level of human skin with a simple heating element or the like. .
That is, as shown in FIG. 2 attached, the ring-shaped stopper is once removed, the seal member is peeled off, and then the ring-shaped stopper is tightened again, and the ring-shaped stopper can be applied to a simple heating means such as a microwave oven. In this case, even if a part of the filled water becomes a steam gas due to heating, the gas in the void in the container passes through the water-repellent gas permeable membrane, so that the inside of the container becomes pressurized or becomes negative pressure. There is nothing to do. Furthermore, the filling water can be completely purified water, and can be a prepared water that is safe and free from the generation of substances that cause allergic abnormalities without breeding bacteria or molds, no matter how long it takes. it can.
