  • Patent number: 5816709
    Abstract: A leak-proof travel bag for carrying items containing liquids, such as personal toiletry products, is provided with a ziplock seal towards the top of the bag. The bag also has one fastener for retaining the top of the bag in a once folded position, and a second fastener attached to a flap for retaining the bag in a twice folded position. Optionally, located inside the bag is an absorbing membrane that prevents liquids that might have become free from their original containers during travel from reaching the two folds that protect the ziplock seal.
