The present invention relates to a cover having a heat insulating property and floating on an upper portion of the liquid material. More specifically, the upper layer cover and a lower layer cover corresponding to the air can be injected therein, and the area is expanded on the side. It relates to a cover having an expandable wing that can be.

Conventionally, when there is a need to store water or other liquid substances capable of evaporation or volatilization for a long time in artificially formed ponds or swimming pools and large containers, when exposed to outdoor air in a natural state, the atmosphere is caused by temperature difference. Various methods have been proposed to solve the problem of the significant loss of liquid materials stored or managed due to evaporation to the medium.

In order to minimize the contact with the outside air while floating on the upper surface of the liquid material that needs to be preserved, a floating cover can be considered, but when snow or rain accumulates on the upper surface of the cover, the floating force is lost. Since it sinks to the lower part of the liquid material can not achieve the desired purpose, when using a foam layer having a plurality of pores therein can be positive to maintain the floating force, but of course the complexity of the process of manufacturing the foam layer In case of transporting it to the actual place of use, or in storage, a problem arises due to the large volume of the foam.

On the other hand, unlike the previous generations, who have been running forward without success for success, on the other hand, modern people are investing a lot of time to work hard for their own success and enjoy their leisure while maintaining their health. Is the reality. As a way of doing this, many people spend their time looking for swimming pools and swimming to stay healthy. However, more modern people are getting better at living and swimming in their own homes. By the way, if you have a swimming pool in your home, it's good to see in the daytime, but if people use the swimming pool, it's not a problem. There was always a risk of falling into a safety accident.

Therefore, in order to prevent evaporation or volatilization of the liquid material and to prevent a person or object from falling into the liquid material, there is a need for a cover that can float on the upper surface of the liquid material. Conventionally, there has been a cover which floats in a pool by attaching a foam between films. However, since the protective cover increases the volume of the protective cover due to the attachment of the foam, it caused a lot of inconvenience.
