1. Field of Invention
The invention relates to a waterproof bag, and more especially to a waterproof bag that can be well sealed by plastic strip members.
2. Related Prior Art
Generally speaking, it's a big concern for people that their personal belongings often get wet when they participate in water sports activities, and thus a various kinds of bags with waterproof functions are developed. However, for those doing surfing activities, they pay more attention to the watertight bags with much higher sealing quality and portable functions than those regular waterproof bags. Take an example of the magnetic tape disclosed in U.S. Pat. No. 7,187,261, the magnetic tape includes a pair of strip members covering the magnet that are welded together, which is applied to two opening sides of the a waterproof bag by using high frequency welding whereby the magnet is encapsulated in hermetically sealed capsules to replace the conventional technique using zipper seals.
Nevertheless, the shortcomings of this kind of the magnetic tape are high cost with poor sealing effects. In practical uses, the fact that this kind of bags having magnetic tape barely resist the sudden severe impact of incoming waves just by the magnetic attraction, which therefore limits the waterproof functions. Accordingly, there is a need to provide a high-quality water resistance of the waterproof bags that can resist tremendous forces of waves without affecting watertight function.
SUMMARY OF INVENTIONTo solve aforementioned problems, a new waterproof bag of the present invention is therefore provided.
Specifically, the present invention is directed to a waterproof bag, which comprises a bag body, first and second strip members and a fastener. The bag body is essentially consisting of two flexible sheets and has an opening facing upward at a top edge thereof The top edge of the bag body is to be folded over to turn the opening upside-down. The sealing clip structure is disposed at the top edge of the bag body and includes first and second strip members that are respectively disposed at opposite sides of the bag body for sealing the opening of the bag body. The fastener is disposed on the bag body for fastening the sealing clip structure once the top edge of the bag body with the sealing clip structure thereon is folded over and turns the opening of the bag body upside-down.
Preferably, a pair of connecting rings may be respectively disposed at opposite edges of the bag body.
Preferably, the bag body is formed with a fold line about which the top edge of the bag body with the sealing clip structure thereon is folded over to a position where the sealing clip structure is ready to be fastened by the fastener.
Preferably, the first strip member includes a jutting section extending downward from a bottom thereof The jutting section has a bottom edge that is tapered in thickness toward an inner side thereof and joined to the fold line. Besides, each of the first and second strip members may include a connecting section extending upward from a top thereof and extending outside the top edge of the bag body. The connecting sections of the strip members together are formed with a zip-lock seal therebetween.
Preferably, each of the two connecting sections of the first and second strip members may include a lip portion extending upward and outward therefrom so that a clearance is defined between the lip portions of the connecting sections when the opening of the bag body is sealed by the first and second strip members. Moreover, the connecting sections may be formed with a plurality of ribs on opposed inner sides thereof
Preferably, the first strip member and the fastener are arranged on the same side of the bag body and are together configured to form a zip-lock seal therebetween once the top edge of the bag body with the sealing clip structure thereon is folded over. Furthermore, the second strip member may be formed at opposite ends thereof with a pair of projections. The fastener, on the other hand, has a pair of folding sections at opposite ends thereof and extending outside the bag body. Each of the folding sections of the fastener defines an engaging hole for reception of a respective one of the projections of the second strip member when the folding sections are folded over back to the bag body.
Compared with the traditional bag, the present invention is a waterproof bag with absolute positive watertight effects. Specifically, the opening of the bag body with the sealing clip structure thereon is folded down, which makes the bottom edge of the first strip member press against the fold line of the bag body, so as to firmly seal the opening of the bag body. Secondly, the fastener secures the sealing clip structure once the bag body is folder over, by engaging with the first strip member, the second strip member or both. Accordingly, the present invention achieves functions of great watertight seal to resist tremendous forces of waves while being used in water sports activities.
Other features, objects, aspects and advantages will be identified and described in detail below.

As described above, the waterproof bag 100, 200 of the present invention has the bag body with a material having a characteristic of high friction, which helps sealing the opening of the bag body by itself Moreover, the opening of the bag body is secondly sealed by the zip-lock seal of the first and second strip members of the sealing clip structure. But not just yet, the top edge of the bag body with the sealing clip structure thereon is further folded over to have the bottom edge of the first strip member press against the fold line of the zip-lock seal, creating a third sealing effect. This allows the two flexible sheets of the bag body to be firmly bond to each other and therefore the opening of the bag body is well sealed. The first and second strip members are then fastened onto the fastener to achieve great watertight effects.
It will be appreciated that although a particular embodiment of the invention has been shown and described, modifications may be made. It is intended in the claims to cover such modifications which come within the spirit and scope of the invention.
