Description

Tumbler with sterilization function {TUMBLER WITH STERILIZATION FUNCTION}

The present invention relates to a tumbler having a sterilization function, and more particularly, a healthier beverage intake environment by simultaneously sterilizing and sterilizing not only the inner and outer surfaces of the periphery of the container, but also the part (upper part) where the user's mouth is frequently touched and the beverage in the container. It relates to a tumbler equipped with a sterilization function to promote

The domestic plastic consumption surveyed by the Korea Consumer Agency in 2018 was 132,7 kg per person as of 2015, which is higher than the US 93.7 kg, China 57.9 kg, and Japan 65,9 kg. It was found that indoor stores such as specialty stores handle the most disposable plastic cups.

Accordingly, the Ministry of Environment introduced a “disposable cup prohibition policy” in indoor stores to minimize the consumption of disposable cups. The practical limitations of using disposable plastic cups or disposable paper cups have been pointed out.

The use of tumblers is strongly recommended as part of a countermeasure against environmental problems such as global warming and marine pollution caused by the use of disposable plastic cups or disposable paper cups.

The aforementioned tumbler refers to a large cup without a heel or handle, and a flat bottom. It has a relatively large capacity to share beverages over a long period of time, is light in weight, and has a good portability and dual vacuum insulation structure. With several advantages such as excellent thermal insulation and storage with an openable lid, many people use it in daily life as well as sports and leisure activities.

On the other hand, as with most tableware and household containers, the tumbler is also a household container for beverages, so scale (stains due to sediment in water, etc.) may get stuck and bacteria cannot but multiply. Moreover, since it has a relatively large capacity, drinks are shared over a long period of time, whereas washing is not hygienically clean because the space for washing is long, about once a day.

As such, if the tumbler is not properly managed and the tumbler gets scaled or bacteria multiply, it will smell and be hygienically vulnerable. In particular, in the hot season, such as summer, it has to be washed (sterilized) frequently as it reveals more hygienic problems.

Furthermore, for the prevention of a new type of coronavirus disease 19 (COVID-19) that first occurred in Wuhan, China in December 2019 and is now spreading around the world, not only tableware used by everyone but also personal use The hygiene of the container also requires more attention than before, so cleaning and sterilization of the tumbler is a very important time.

However, the tumbler has a rather complicated structural nature of the opening and closing structure of the beverage outlet for securing portability and heat retention and convenience for drinking, and the sealing structure to prevent liquid leakage when the outlet is opened and closed. Uneasy.

In order to solve the above problems, through Korean Patent Registration No. 10-1653590, a tumbler having a sterilization function that can be used more hygienically by sterilizing the inside of the tumbler with the antibacterial power of ultraviolet rays has been disclosed.

1 is a cross-sectional view of a tumbler having a sterilization function according to the prior art. The conventional tumbler having a sterilization function, as shown in FIG. a container 910 divided into a first space 912 for accommodating a beverage and a second space 913 for accommodating an ultraviolet sterilization module 940; a stopper 920 for opening and closing the opened upper surface of the container 910; a sensor unit 930 provided at the upper end of the container 910 to detect whether the container 910 is open or not and to apply a signal when the container 910 is closed; A charging receiver 941 mounted in the second space 913 of the container 910 and receiving an induced voltage from the outside, and a battery ( 942), a UV lamp 943 receiving power from the battery 942 to irradiate UV rays, and receiving a signal from the sensor unit 930 to control the driving of the UV lamp 943 for a preset time an ultraviolet sterilization module 940 configured with a controller 944 to sterilize the inside of the container 910 by irradiating ultraviolet rays for a preset time when the container 910 is closed; and a charging base 950 having a built-in charging transmitter 951 for generating an induced voltage by receiving power from the outside so as to transmit an induced voltage to the charging receiver 941 .

According to the related art, a UV sterilization module 940 is provided at the lower end of the container 910 and sterilizes the inside of the container 910 with the antibacterial power of UV radiation emitted from the UV sterilization module 940, thereby making a tumbler. can be used more hygienically.

In addition, by driving the UV sterilization module 940 using the power charged by the wireless charging method, it is easy to wash the tumbler, improves the convenience of use, and only when the container is closed by closing the stopper 920 of the tumbler By irradiating UV light from the UV sterilization module 940, sterilization power and safety are improved, and the lifespan of the UV sterilization module 940 is extended.

However, since the ultraviolet sterilization module 940 for sterilization of the container 910 is provided in the second space 913 provided at the bottom of the container 910, the sterilization effect by the ultraviolet sterilization module 940 is effective for the container. (910) has no choice but to be concentrated (focused) only on the lower part, and this has the disadvantage that the sterilizing power of the upper surface of the container 910 to which the stopper 920 is coupled or the proximal portion thereof is greatly reduced.

After all, it is urgent to research and develop a tumbler that can increase the sterilization (sterilization) efficiency by sterilizing the inside and outside of the container and simultaneously sterilizing the upper opening of the container and the beverage contained in the container.
