Abstract
A waterproof bag having three layers, namely inner and outer layers made of a rather durable non-waterproof fabric, and an intermediate layer that is positioned between the inner and outer layers so as to be protected from sharp objects and the like. The bag has an upper circumferencial edge defining a bag opening, and the upper edges of the three bag layers are sewn together. There is a moderately stiff closure belt or strap at the upper portion of the bag. When the bag is to be closed in its waterproof containing position, the belt or strap and the upper portion of the bag is folded over several times, and the outer ends of the belt are brought together to form a loop. This provides a substantially waterproof container. The container is also shown as a containing section of a backpack.
Claims22
A waterproof container unit particularly adapted for use in camping and backpacking or the like, but also being adapted for use in other situations or activities where the container is subjected to impacts, sharp objects and other forms of abuse, said container unit comprising:
- a) a flexible container comprising three separately formed bag components, each of which has an upper edge portion, with the upper edge portions of the three bag components being joined to one another with portions of the three bag components below the upper edge portions being substantially unjoined from one another, so that substantial regions of the bag components are separate from one another, said three bag components comprising:
- i) an outer flexible and durable first bag component at an exterior surface of the container;
- ii) an inner flexible and durable second bag component positioned within the first bag component at an inner surface of the container;
- iii) an intermediate water proof third bag component positioned between the first and second bag components;
- b) said three bag components collectively comprising a container wall comprising a side wall portion and a bottom wall portion closing the side wall portion, said side portion having an upper container edge portion defining an upper container opening;
- c) said container wall comprising a lower containing wall section defining a containing chamber and an upper closure wall section comprising front and rear upper wall portions that can be positioned against one another, said closure wall section comprising a plurality of closure wall sub-sections extending along the upper closure wall section, with adjacent sub-sections being capable of one being folded downwardly relative to another about an intermediate folding portion so as to be in a folding configuration where interior surface portions of the front and rear upper wall portions press against one another in sealing relationship;
- d) a closure retaining device having a retaining position to retain the closure wall subsections in their folded configuration.
