CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. Pat. application Ser. No. 07/017,631, field Feb. 24, 1987, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates generally to waterproof pouches for small personal items and, more particularly, to a waterproof pouch removably attachable to wearing apparel, such as swimsuits. 
     U.S. Pat. No. 1,164,011 discloses a waterproof pocket removably attachable to a bathing suit. The bathing suit is provided with a slit for receiving the pocket, and the pocket is attached to the portion of the bathing suit above the slit by four apertured knobs. The knobs are poked through the material of the bathing suit and are fastened in place on the suit by split rings inserted through the apertures in the knobs. 
     Other examples of bathing suits having waterproof pockets are shown in U.S. Pat. Nos. 1,142,509 and 1,603,299. Also, U.S. Pat. Nos. 1,003,711, 3,611,444, and 4,266,300 disclose detachable pockets for wearing apparel. Further, examples of waterproof pouches with multiple closure means are disclosed in U.S. Pat. Nos. 3,998,304 and 4,421,450. 
     SUMMARY OF THE INVENTION 
     The present invention provides a waterproof pouch which is readily releasably clampable to an edge portion of wearing apparel. The pouch is constructed of flexible impermeable plastic sheet material and includes a readily openable and recloseable waterproof seal protected by a closure flap having readily openable and recloseable fastening means. 
     In the preferred embodiment of the invention, the waterproof seal is provided by a pair of complementary sealing strips each having tongues and grooves releasably interlockable with those of the other. Also, the pouch is clamped by means of a readily openable and closeable over-center snap-acting clamp. The clamp is preferably attached to the pouch by a separate reinforcing strip which extends over a portion of the clamp and is heat-sealed to the pouch. 
     The above, as well as other advantages of the present invention, will be readily apparent to one skilled in the art when the following detailed description of the invention is read in conjunction with the attached drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings, FIGS. 1-4 show a waterproof pouch 10 constructed in accordance with the invention. The pouch 10 includes a flexible plastic rear wall 11a having an upper extension 11b which serves as a closure flap, and a flexible plastic front wall 12 heat-sealed or otherwise adhered to the rear wall 11a along lower and opposite side edge portions and forming an open-top compartment therewith. 
     A transversely extending fastening strip 14 is adhered to an outer side of the front wall 12 about midway between its upper and lower edges, and a complementary fastening strip 15 is adhered to an inner side of the closure flap 11b along an edge portion which is a lower edge portion when the flap is closed. The strip 14 is provided with small hooks and the strip 15 is provided with a wooley or looped surface. Such mating hook and loop fastening strips are available under the trademark &#34;VELCRO&#34;. They are readily openable and recloseable. 
     A clamp 16 is secured in place on the outer side of the rear wall 11a by a slotted rectangular piece 18 of flexible plastic heat-sealed or otherwise adhered to the rear wall 11a along an upper edge 18a and opposite side edges 18b. The clamp 16 may be termed a one-piece, overcenter snap-acting mechanism and is more clearly shown in FIGS. 4 and 5. 
     The clamp 16 is made of semi-rigid plastic in one piece, but may be considered as including three parts connected together by thin sections. Thus, a mounting base 16a, an operating lever 16b, and a generally U-shaped spring 16c are provided. The mounting base 16a is connected by a thin section 16d to one end of the spring 16c and by a thin section 16e to the operating lever 16b. The other end of the spring 16c is connected by a thin section 16f to the operating lever 16b. The thin sections 16d, 16e, and 16f act as pivotal connections, being more flexible than the remainder of the clamp 16. A fulcrum post portion 16g of the mounting base projects through the slot in the flexible plastic piece 18. Mating portions of the base 16a and the operating lever 16b are provided with toothed surfaces for gripping an edge of wearing apparel 22 when the clamp 16 is closed thereon, the wearing apparel 22 being shown in phantom in FIG. 4. When the clamp is in its closed position as shown in FIG. 4, the spring 16c urges securely grip the wearing apparel. 
     When not in use, the pouch 10 is generally flat with the rear wall 11a in contact with the front wall 12 throughout, but the walls are separable, as shown in FIG. 4, except at their lower and opposite side edges, to define a waterproof compartment 10a for receiving an item in the pouch. 
     With reference to FIGS. 1, 4 and 6, a flexible plastic sealing strip 12a is provided as an extension of the front wall 12, and a complementary sealing strip 20 is adhered to the upper edge portion of the inner side of the rear wall 11a. The sealing strips 12a and 20 are provided with releasably interlockable tongues and grooves, as shown in FIG. 6, for providing a waterproof seal. 
     To insert an item in the pouch 10, the closure flap 11b may be lifted by grasping a lower edge portion and pulling the VELCRO fastening strip 15 away from its complementary fastening strip 14. The sealing strip 12a may then be pulled away from the complementary sealing strip 20 to open the pouch. After the item is inserted, the strips 12a and 20 may be pressed together at their tongue and groove portions to form a waterprooof seal, and the closure flap 11b may be fastened in a closed position by pressing the fastening strips 14 and 15 together. 
     To clamp the pouch 10 to an item of clothing or the like, the operating lever 16b may be pulled upwardly to an open position with one hand while holding the mounting base 16a with the other hand. The lower toothed portion of the mounting base 16a may then be placed in overlying relationship with an item of clothing and the opening lever 16b may then be snapped back to the closed position to securely clamp the clothing between the operating lever and the mounting base. 
     It should be noted that various modifications may be made in the structure shown and described without departing from the spirit and scope of the attached claims.
