Tumbler with sterilization function {TUMBLER WITH STERILIZATION FUNCTION}

The present invention relates to a tumbler equipped with a sterilization function, and more specifically, to provide a healthier beverage consumption environment by simultaneously sterilizing and disinfecting the inner and outer surfaces of the container as well as the area (top portion) frequently touched by the user's mouth and the beverage in the container. This relates to a tumbler equipped with a sterilization function to promote .

According to a 2018 survey by the Korea Consumer Agency, domestic plastic consumption was 132.7kg per person in 2015, which is higher than the United States' 93.7kg, China's 57.9kg, and Japan's 65.9kg. It was found that indoor stores such as specialty stores handle the most disposable plastic cups.

Accordingly, the Ministry of Environment introduced a policy to ban the provision of disposable cups in indoor stores to minimize the consumption of disposable cups, but when using reusable cups (mugs, etc.) inside the store and leaving the store, The practical limitation of using disposable plastic cups or disposable paper cups has been pointed out.

The use of tumblers is actively recommended as a response to environmental problems such as global warming and marine pollution caused by the use of disposable plastic cups or disposable paper cups.

The tumbler mentioned above refers to a large glass without a heel or handle and with a flat bottom. It has a relatively large capacity for sharing drinks over a long period of time, is light in weight, is easy to carry, and has a double/vacuum insulation structure. It has many advantages, such as excellent heat retention and storage with an openable lid, so many people use it not only in daily life but also in sports and leisure activities.

On the other hand, like most tableware and household containers, the tumbler is also a household container for holding drinks, so water stains (stains caused by sediment in the water, etc.) may form and bacteria are bound to proliferate. Moreover, since it has a relatively large capacity, drinks are shared over a long period of time, but washing is only once a day, and the interval between washings is long, so it is not hygienically clean.

Likewise, if the tumbler is not maintained properly and water stains or bacteria grow on the tumbler, it will smell and become hygienic. In particular, in hot seasons such as summer, it must be cleaned (sterilized) frequently because it presents more hygiene problems.

Moreover, to prevent the new type of coronavirus disease 19 (COVID-19), which first emerged in Wuhan, China in December 2019 and is currently spreading around the world, all utensils that are shared by everyone as well as personal utensils must be used. The hygiene of containers also requires greater attention than before, making cleaning and sterilizing tumblers very important.

However, the tumbler has a somewhat complicated structural characteristic of the opening and closing structure of the beverage discharge port to ensure portability, heat retention and convenience of drinking, and the sealing structure to prevent liquid leakage when opening and closing the discharge port, making it difficult to clean and clean the relevant parts. Uneasy.

In order to solve the above-mentioned problems, a tumbler with a sterilization function that sterilizes the inside of the tumbler using the antibacterial power of ultraviolet rays to enable more hygienic use has been disclosed through Republic of Korea Patent No. 10-1653590.

Figure 1 is a cross-sectional view of a tumbler with a sterilizing function according to the prior art. As shown in Figure 1, the conventional tumbler with a sterilizing function has an open upper surface and a transmission plate 911 through which ultraviolet rays are transmitted. 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 that opens and closes the open upper surface of the container 910; A sensor unit 930 provided at the top of the container 910 to detect whether the container 910 is opened and closed 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), an ultraviolet lamp 943 that receives power from the battery 942 and irradiates ultraviolet rays, and receives a signal from the sensor unit 930 to control the operation of the ultraviolet lamp 943 for a preset time. An ultraviolet sterilization module 940 that consists of a control unit 944 and sterilizes the inside of the container 910 by irradiating ultraviolet rays for a preset time when the container 910 is closed; It is characterized in that it includes a charging base 950 that has a built-in charging transmitter 951 that receives power from the outside and generates an induced voltage to transmit the induced voltage to the charging receiver 941.

According to Chinese technology, an ultraviolet sterilization module 940 is provided at the bottom of the inside of the container 910, and the inside of the container 910 is sterilized using the antibacterial power of ultraviolet rays emitted from the ultraviolet sterilization module 940, thereby making the tumbler can be used more hygienically.

In addition, by driving the ultraviolet sterilization module 940 using power charged by wireless charging, it is easy to clean the tumbler and improve convenience of use, and only when the container is closed by closing the cap 920 of the tumbler. By irradiating ultraviolet rays from the ultraviolet sterilizing module 940, sterilizing power and safety are improved, and the lifespan of the corresponding ultraviolet sterilizing module 940 is extended.

However, since the ultraviolet sterilizing module 940 for sterilizing the container 910 is provided in the second space 913 provided at the bottom of the container 910, the sterilizing effect by the ultraviolet ray sterilizing module 940 is not effective in the container 910. (910) It has no choice but to be concentrated (focused) only on the lower part, which has the disadvantage of greatly reducing the sterilizing power on the upper surface of the container 910 or the adjacent area to which the stopper 920 is coupled.

In the end, research and development of a tumbler that can increase sterilization (disinfection) efficiency by simultaneously sterilizing the top of the opening of the container and the beverage contained in the container in addition to sterilizing the inside and outside of the container is urgently needed.
