DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baby bottle for infant supplies, and more particularly to a baby bottle already filled with sterile purified water for dissolving milk. In particular, the present invention has a seal material that can be opened manually at the opening, but does not directly apply a load to the seal material even if the impact at the time of dropping or the internal pressure during autoclave sterilization increases, and the sealing water is sealed. The present invention relates to a baby bottle that can maintain its properties for a long time.

[0002]

2. Description of the Related Art A conventional baby bottle comprises a container body made of polycarbonate, an artificial nipple made of synthetic rubber, a stopper formed into a ring-shaped resin, a hood, and the like. The artificial nipple is joined to the open end surface of the container body. A threaded portion is formed at 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.
In the case of using such a baby bottle, first, boiling water is put into the container body, then the milk is dissolved, and after cooling to a predetermined temperature, breast feeding 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. In addition, at the time of breastfeeding, even if the infant is strongly sucked into the nipple and a negative pressure is generated in the container body and the nipple is crushed, air is supplied from the vent hole into the container. Then, after nursing, the conventional baby bottle is disassembled into respective members, washed and disinfected by boiling, dried, and used again.

[0003]

By the way, in the conventional baby bottle, it takes time to wash and reuse each time it is used. For this reason, cheap disposable baby bottles are desired. Further, in the conventional baby bottle, no milk solution is supplied. Therefore, the following problem occurs. Conventionally, most of the milk solution is boiled tap water. However, it is difficult to use it outdoors or in emergencies without boiling equipment. Tap water is once boiled. For this reason, after dissolving the milk powder in hot water of about 70 ° C., the milk powder is cooled to about 38 ° C. by a cooling device or the like, and then nursing is performed.
Furthermore, recently, in infants with hypersensitivity such as atopy,
In some cases, the reaction may be sensitive due to certain resident bacteria or other proteins in tap water. In such a case, use of tap water or the like in preparing milk causes a problem. Recently, a disposable baby bottle is filled with a pasteurized and flash sterilized milk solution in advance. However, since such a baby bottle is in the form of a milk solution, it can be stored in a refrigerator or a cooler box at best for only three days. It is also difficult to supply milk solutions of other varieties.

[0004] In view of the above, sterile water,
It is conceivable to fill a milk solution such as distilled water, RO water, or autoclave sterilized water. Such a solution does not boil, has no hypersensitivity substance, and has no water rot. However, the following problem also occurs in such a case. Sterile water, sterile water and the like must be kept liquid-tight for a long time without being contaminated in the baby bottle. For this reason, it is necessary to seal the opening of the baby bottle in a liquid-tight manner with a conventionally known sealing material. In addition, a notch or the like for pull-opening must be formed in the sealing material. However, with the sealing property of such a sealing material, the impact may be transmitted to the seal portion when the device is accidentally dropped or dropped by a pending machine during manufacturing, and the sealing material may be broken. In the case of autoclave sterilization, etc., there is no problem if the pressure adjustment during the sterilization process is performed accurately, but in the sterilization process with rough pressure adjustment, a pressure difference occurs between the inside and the outside of the baby bottle, which is also a problem. There is a possibility that the sealing material may be broken. Furthermore, the sterile water in the baby bottle does not directly become drinking water, but becomes drinkable only when the milk is dissolved. Therefore, space for filling milk is desired in the baby bottle. Accordingly, an object of the present invention is to provide a convenient, safe and sanitary disposable baby bottle, which has a seal material that can be opened by hand at the opening, while increasing the impact upon dropping and the internal pressure during autoclave sterilization. An object of the present invention is to provide a baby bottle in which a load is not directly applied to the sealing material and the sealing property of the filling water can be maintained for a long period of time.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a resin bottle having a constant volume and a transparency, which has an opening through which an artificial nipple is joined in a liquid-tight manner during use. An openable sealing material is provided, and the resin bottle is filled with a liquid in an aseptic or sterile state, and a shock-resistant buffer gas is filled in the resin bottle in a range of 15 to 45% by volume. By providing a baby bottle characterized by having
The above object has been achieved.

The above-mentioned resin bottle having a constant volume does not need to have a complete constant volume. Usually, the volume may be reduced once by elastic deformation of a wall or the like due to impact or the like. It will return. Further, under the influence of the molding history and the like, it may be slightly shrunk or expanded by a heating treatment such as autoclave sterilization, but it has a constant volume at room temperature due to the above-mentioned elastic deformation. The above-mentioned transparent resin bottle is required to have transparency so that at least the level of the filling liquid inside can be confirmed. Resin bottles are usually blow molded,
This is a molded product obtained by a general-purpose molding method such as injection molding and vacuum molding, and a commonly used blow molded product can be used. The opening of the bottle molding is formed with a screw or the like of a stop ring member of the artificial nipple or the like so that the artificial nipple or the like can be joined in a liquid-tight manner.

The hand-openable sealing material is capable of sealing the opening of the resin bottle in a liquid-tight manner for a long period of time, while it can be easily opened with a hand, that is, a finger or the like. The sealing material is a resin film, a sheet, a molded lid, or the like that can be thermally welded to the opening, and may be a laminated material such as an aluminum foil. It is desirable that the resin such as a film, a sheet, or a molding lid is compatible with the resin of the opening, for example, a general-purpose resin similar to the resin of the opening is used. The aseptic or sterile liquid in the resin bottle does not cause water decay for a long period of time, and has high safety without the necessity of boiling when milk is dissolved. The resin bottle is filled with a buffer gas, for example, a gas such as air or an inert gas such as nitrogen or carbon dioxide in a range of 15 to 45% by volume, particularly 20 to 40% by volume, and furthermore 25 to 35% by volume. ing. If the gas is charged within such a range, the sealing property of the weak seal material is maintained even when an impact due to a drop or a pressure difference occurs during sterilization of a sterile liquid or a sterile liquid during autoclave sterilization. That is, when the gas filling falls below the above range, when the resin bottle instantaneously causes a large change in volume due to the impact at the time of falling, the impact extends to the weakest part of the sealing property, and the sealing material is formed by the so-called water hammer state. May break.
On the other hand, if the gas filling exceeds the above range, the gap becomes excessively large, and the handling of the baby bottle becomes poor due to the necessity of increasing the volume of the baby bottle. Further, by filling the above gas, when the baby bottle is used, the filling liquid is not directly drinkable but a predetermined amount of milk or the like is added to the bottle. For this reason,
The generation of voids in the baby bottle does not cause the filling liquid to be discarded for the introduction of milk. Mixing and dissolving milk is also easy. Therefore, there is no danger of aseptic destruction of the inside of the baby bottle at the time of production, transportation, storage, and at the time of use,
The sterile or sterile liquid in the baby bottle can be used in any place without boiling and without fear of hypersensitivity.

Is filled. Thereby, the sterile liquid can be easily filled in the baby bottle, and breastfeeding of the hypersensitive patient can be performed with confidence. It is desirable that the sterilizing filter has a pore size of 0.6 μm or less, and 0.4 μm or less for removing debris other than bacteria. According to a third aspect of the present invention, it is possible to provide a sterilizing solution in the baby bottle according to the first aspect of the present invention, wherein the sterile solution or the sterilizing solution is autoclaved together with the resin bottle. And By providing such a sterilizing liquid, complete water rot and the like are prevented, and long-term storage is possible. The temperature of the autoclave sterilization is preferably in the range of 100 to 140 ° C, particularly preferably in the range of 105 to 120 ° C. If the temperature is lower than the above range, the sterilization time is long, and if the temperature is higher than the above range, the resin bottle may be thermally deformed. Further, pressure regulation becomes a problem during the autoclave sterilization, but a load is not applied to a sealing material or the like due to the buffer gas, and rough setting for pressure regulation is possible.

A fourth aspect of the present invention is directed to obtaining the autoclave sterilizing solution according to the third aspect of the present invention, wherein the resin bottle is made of a polypropylene resin. Desirably, the resin of the resin bottle is a thermoplastic resin, and versatile polyethylene, olefinic resin such as polypropylene, phenolic resin,
Examples thereof include a carbonate resin, a polyester resin, a cellulose resin, and a polyamide resin. However, among the above-mentioned resins, polyolefin-based resins are preferable as those which are hygienic and less affected by solutes and the like. Polyethylene terephthalate, polypropylene, and polycarbonate are preferred as the preferable resin having excellent non-constant volume and transparency. Above all, it is desirable that the resin is a polypropylene resin that can withstand the above-mentioned autoclave and has good moldability.

[0010] The invention of claim 5 or 6 aims to specifically provide the seal material which can be opened manually according to the invention of claim 1. It is characterized in that it is attached to the opening so that it can be peeled,
Second, the hand-openable sealing material is characterized in that a cut-out portion for pull-opening is formed. The sealing material is a resin film, a sheet, a resin molded lid, or the like, and the resin used is the same as or similar to the resin at the opening of the resin bottle. Further, it is desirable that the sealing material is a laminated material having such a resin on the bonding surface and has excellent gas barrier properties. These are liquid-tightly adhered to the opening surface by a heat seal. In the case of a seal material that can be peeled open, the peel strength of the easy seal depends on the diameter of the opening and the width of the sticking surface.
2,000 g to 200 g, the opening width is 1 mm or more and 3 mm or less, and if the opening inner diameter is 30 mm or more and 60 mm or less, the peel strength is 3300 g / cm to 66 g / cm. It is desirable to be within the range. If it is within such a range, it can be opened manually, and there is no possibility that the package will be broken by the impact of dropping. Also, the notch formed in the pull-open seal material has a tensile force of 20 when a so-called pull ring is pulled.
Desirably, it is 00 g to 200 g.

According to a seventh aspect of the present invention, there is provided a sterile or sterile liquid for a baby bottle according to the first aspect of the present invention, wherein the sterile or sterile liquid comprises purified water, distilled water in which solid milk is dissolved,
It may be characterized in that it is a solution comprising RO water or a solution containing any of minerals, vitamins, sugars, amino acids and peptides. Therefore, a suitable nutrient milk solution can be provided by appropriately adding oxidation-resistant ascorbic acid, calcium, and the like.

The body wall of the resin bottle 2 is transparent, and is elastically deformed by a slight external pressure. Polypropylene has no functional groups or the like, does not adversely affect the filling liquid, is excellent in transparency, impact resistance, moldability, and has heat resistance enough to withstand heating temperatures such as autoclave sterilization. For this reason, complete sterilization is possible in an autoclave or the like, and there is no problem when applied as a milk solution to infants with hypersensitivity or the like. The resin bottle 2 is filled with the milk solution 5 and the milk solution 5 is filled with 200 mL. The milk solution 5 is sterile purified water filled from the opening 3 of the resin bottle 2 after passing distilled water through a sterilization filter. The milk solution 5 is obtained by making the opening 3 liquid-tight with a sealing material 4 described later and then sterilizing the milk 3 together with the resin bottle 2 in an autoclave. The filter has a pore size of 0.2 μm. Autoclave sterilization was performed at 110 ° C. for about 1 hour. Such a milk solution 5 has no proteins or other allergens, has no growth of molds and bacteria during long-term storage, and does not cause any problem when applied to ARTP patients.

A void 100 mL in the resin bottle 2 is filled with a nitrogen gas 6 as an inert gas as a buffer gas, and the nitrogen gas 6 is replaced and filled through a sterilization filter. Therefore, the filling amount S of the milk solution 5 in the resin bottle 2 is 66.6.
% Of the buffer nitrogen gas 6 is 33.3%.
% By volume. A sealing material 4 is adhered to the surface of the opening 3 of the resin bottle 2, and the sealing material 4 is formed by laminating aluminum foil on the same resin layer as the resin of the opening 3 of the resin bottle 2. The sealing material 4 is adhered to the opening 3 in a liquid-tight manner by heat application.

Next, a case where the baby bottle 1 of the present embodiment is used will be described with reference to FIGS. In the state shown in FIG. 1, the baby bottle 1 is placed in a microwave oven and heated from room temperature to 37 ° C. to 40 ° C. in about 10 seconds by high-frequency dielectric heating. In this case, even if the feeding container 1 is stored for a long period of time, the milk solution 5 does not cause water rot or propagation of bacteria. Therefore, it can be prepared by adding milk powder to a safe milk solution 5 that does not require boiling or the like. For this reason,
Nursing milk can be provided immediately by heating for about 10 seconds in a microwave oven or the like. Further, since the purified water does not show any breeding of bacteria and molds, it is possible to prevent allergies of infant patients such as atopy as much as possible. Therefore, with the milk solution 5 heated to approximately 40 ° C., the stopper 7 is removed, the sealing member 4 is peeled off, and a predetermined milk powder is poured into the resin bottle 2. In this case, since the resin bottle 2 is sufficiently filled with the nitrogen gas 6 to have voids, the milk powder can be easily and safely poured into the resin bottle 2. Then, even when the milk solution 5 and the milk are stirred to produce the milk solution 14 as shown in FIG. 3, the milk solution 14 can be mixed so as not to spill from the opening 3 without forcibly attaching the artificial nipple 8.
