Description

TECHNICAL FIELD The present invention relates to a nipple for a liquid milk powder container,

The present invention relates to a method and an apparatus for post-injection treatment of a nipple and a coupling unit for disposable liquid milk powder containers for use in traveling with a baby, and in particular, to a milk powder container such as a milk powder bottle injected for safety and hygiene of infants Which is produced in the injection process of the nipple and the coupling port, and cleaning and sterilizing for removing foreign substances in a consistent process so as to produce an efficient and hygienic liquid The present invention relates to a nipple for a milk powder container and a post-injection process of a nipple coupling for coupling the nipple to a container, and in particular, to a hygienic treatment method and a treatment device.

A big problem for parents who go out with infants is to feed infants with powdered milk. Separate containers for hot water are provided. Separate milk powder cans are provided so that milk powder can be put into containers when needed. There was a troublesome problem.

In recent years, prefabricated or kit-shaped milk powder containers have been introduced to avoid such troubles and to make it easier for parents with infants to go out.

As an example of such a kit-type milk container, a disposable kneading bottle for infant feeding is disclosed in Korean Patent No. 10-0914500 (registered on August 21, 2009), and as another example, 10-1624291 (registered May 19, 2016) discloses a disposable bottle kit.

In this conventional milk powder container, a nipple is generally connected to an inlet side of a container to be injection-molded. Recently, a product containing liquid milk powder has been marketed and a nipple is combined with a container, And the like.

To this end, a nipple coupling unit for coupling to the inlet side of the liquid milk powder container and a nipple coupled to the coupling unit are manufactured by injection molding and supplied.

The nipple for producing the nipple is usually produced by molding liquid silicone. The nipple coupling for coupling the nipple to the container is produced by, for example, screw injection of polypropylene. In the production process, Or it could get stuck.

In the case of infants, the skin is very weak, and the infants should contact the mouth with the nipple. Therefore, the nipple and nipple joint used in the baby disposable liquid milk powder container with weak resistance must perform sanitization in the post injection molding process.

In connection with the hygienic treatment in the post-injection molding process, in the prior art, the nipple and the coupling port are sprayed with air to be cleaned, and then subjected to assembly, foaming and inspection processes in a clean room and then sterilized and shipped. There is a problem that the sanitary treatment is incomplete due to the completion of the washing, so that the foreign matter is likely to remain, and the minute burrs generated during the injection molding remain, which may damage the soft skin of the infants.

Accordingly, improvement of hygiene control for nipples and joints used in mass-produced liquid milk powder containers has been required.

1 and 2, a nipple 5 is coupled to a coupling port 4 formed on an inner surface of a screw in an inlet portion 2 from which a screw 1 fastened to the container 1 containing liquid milk powder is removed, do.

A radially enlarged flange 6 is formed at the upper end of the coupling opening 4 to prevent the infant from directly touching the lid or gum against the rigid inlet 2 of the container when the infant eats powdered milk. The nipple 5 is in the form of a conventional nipple and is supported at its lower portion by a support portion 7 whose radius is enlarged to be engaged with the upper end of the coupling means 4 so as to be engaged with the inside of the upper end of the coupling means 4, An annular recessed groove 8 is formed on the upper side of the engaging hole 7 and the engaging portion 9 protruding inward from the upper end of the engaging hole 4 is engaged so that the nipple 5 is retained in the engaging hole 4.

The nipple 5 and the coupling port 4 are separately manufactured and supplied in a sterilized and packaged state, and are used when necessary in a container for receiving liquid milk powder.

A nipple 5 produced by injection molding with liquid silicone and a nipple coupling 4 produced by screw injection, for example, polypropylene for coupling the nipple to the liquid milk powder storage container, Nipples and fittings may have microscopic burrs and foreign matter such as residual chemicals.

In the case of infants, the skin is very weak and the infants should contact the mouth with the nipple. Therefore, the nipple and nipple joint used in the baby disposable liquid milk powder container with weak resistance should remove the burr from the injection molding process, need.

For this purpose, in the present invention, as shown in the process chart of FIG. 3, after the air cleaning by the air injection is performed on the injection-molded nipple and its fittings, burr removal, cleaning, inspection, assembly, vacuum packaging, And post-processing such as sterilization.

That is, as shown in FIG. 3, the post-injection processing method of the present invention is a method of manufacturing a post-injection processing method, which comprises: a nipple coupling port formed by injection, for example, by screw injection with polypropylene; After the washing (steps S1 and S1 '), the fine washing process (steps S2, S2', S3 and S3 ') is carried out in a separate processing device 10 and dried (steps S4 and S4' The nipple and the coupling port are assembled (step S6), vacuum packaged (step S7), and inspected (step S8) to obtain a sterilized gas (for example, (Step S9) with an EO gas (e.g., EO gas).

In the above steps S1 and S1 ', the foreign substances on the surface of the nipple and the nipple coupling hole are firstly removed in the injection process by air cleaning as a cleaning pre-treatment.

Then, it is transferred to a separate processing device 10 and subjected to a precise washing process by washing water. The precise cleaning process is performed by ultrasonic cleaning (steps S2 and S2 ') for generating ultrasonic waves in the water tank and washing residual chemical substances and foreign substances on the surface by the washing water (steps S2 and S2'), Residual matter and foreign matter are removed from the nipple and the coupling port (steps S3 and S3 '), and then sterilized hot air or dry air is supplied and dried in the next steps S4 and S4'. Details of the processing apparatus 10 will be described later.

The nipple and the coupling port which have undergone the precise cleaning process in the processing apparatus 10 are checked in the clean room 60 for the presence or absence of foreign substances or the like by means of a magnifying glass (steps S5 and S5 '), (Step S6). The assembled nipple and the coupling hole are vacuum-packed in step S7 and subjected to inspection (S8).

Then, it is sterilized with EO (Ethylene Oxide) gas and shipped as a finished product. The EO gas is widely used for disinfection of instruments sensitive to heat and sensitive to moisture, such as fine and detailed surgical instruments, various plastic and rubber products, various catheters and endoscopes as sterilization materials using strong toxicity.

In the present invention, following the air cleaning steps S1 and S1 ', ultrasonic washing in the water tank in steps S2 and S2' in the processing unit 10 for cleaning with the washing water, S3 '), it is possible to remove residual chemical substances and foreign substances which may remain on the surface during the injection process by washing with bubbles in the water tank, and even if the minute burrs which may be present in the nipple or the coupling port can be removed, Since the sanitization process can be performed and the drying process is performed in steps S4 and S4 ', the hygiene process absolutely required for infant feeding can be efficiently performed.
