Description

Sterilizer for feeding bottle

The present invention relates to a nursing bottle sterilizer for heating and sterilizing the nursing bottle by supplying steam to a processing container containing the nursing bottle.

Generally speaking, as a sterilization method for feeding bottles, boiling sterilization using hot water is known. The boiling disinfection is as follows: using a deep-bottomed cooking pot, etc., soak the feeding bottle in boiling hot water for a certain period of time, and use heat to sterilize the feeding bottle.

However, in this boiling disinfection method, in order to take out the sterilized feeding bottle, it is necessary to move the pot with hot water to the sink, and add cold water to the hot water and pour it into the sink. Troublesome.

Therefore, as an alternative to the previous boiling sterilization method, a steam sterilization method using steam is proposed (for example, Patent Document 1). In the steam sterilizer, the feeding bottle of the treatment object is contained in a specific treatment container, and steam is supplied into the treatment container, thereby sterilizing the feeding bottle by the heat of the steam.

According to this steam sterilization method, there is no need for cumbersome work such as hot water treatment after the sterilization of the boiling sterilization method, and the sterilization work can be performed more easily than before.

Furthermore, in the steam sterilization method, the sterilized feeding bottle can be housed in the processing container until the next use. Therefore, compared with the boiling sterilization method, it is also advantageous in terms of hygiene.
