It has the advantages of simple structure, easy operation and low manufacturing costs.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a storage bag and specifically relates to a waterproof storage bag being a commodity used in daily life.[0002]Currently, a waterproof storage bag generally comprises a bag body and a sealable opening. After a user has put an object such as a mobile phone, a camera or a portable personal computer into the bag body, the user could simply close the sealable opening so that water outside the bag body would not be able to enter the bag body. In general, the sealable opening could be tightened by a zipper. However, if a user inadvertently fails to fasten the zipper completely, or if the user fails to notice that the zipper is broken due to long-term use, water outside the bag body would then enter the bag body. As a result, the object inside the bag body would get wet and thus damaged. Therefore, there is a market demand for a waterproof bag which could indicate to a user whether its waterproof function is still functioning...

AI Technical Summary

Benefits of technology

The present invention is a waterproof bag that can indicate whether its waterproof function is still properly functioning. It has advantages of simple structure, easy operation, and low manufacturing costs. The bag opening is provided at an upper end of the bag body, which can also be provided with a hanging string or a string hole for increased portability. The bag is made of a multi-porous resilient member surrounded by an air-permeable member made of air-permeable fabrics or plastic material. The air-permeable member is thicker at four sides to leave a recess area in middle part so that an object is easily fixed in position inside the bag body. The opening of the bag can be manually pressed to compress the multi-porous resilient member and restore its original condition, ensuring tight sealing. The soft plastic material is easy to change its shape and restore its original condition, and smooth surfaces can adhere to each other without any gaps, resulting in better sealing effect and longer durability. The vacuum storage bag does not contain any hard components and is therefore safe and convenient for use.

Problems solved by technology

However, if a user inadvertently fails to fasten the zipper completely, or if the user fails to notice that the zipper is broken due to long-term use, water outside the bag body would then enter the bag body.

As a result, the object inside the bag body would get wet and thus damaged.
