Reservoir shading apparatus and method

Abstract

A reservoir shading structure made of multiple consumer beverage containers. The containers each have a bottle portion, and a top portion preferably with a collar. The top portion is removed, inverted, and replaced in the bottle portion to extend into the bottle portion. The top portion is hermetically sealed to the bottle portion and a cap is welded into the top portion to hermetically seal the consumer beverage container. The consumer beverage containers are UV resistant, made of NSF/ANSI Rule 61 compliant material, and may include carbon black in their construction. Multiple consumer beverage containers are placed in a uniform layer across the surface of the reservoir to form a shading structure that reduces evaporation and microbial growth.

9. A method of conserving water in a reservoir and avoiding chemical and microbial contamination, comprising the steps of: obtaining a consumer beverage container having a bottle portion for holding a beverage and a top portion for decanting the beverage; identifying a cut line under a collar on the top portion; heating the consumer beverage container adjacent the cut line; pressing the top portion into the bottle portion when the consumer beverage container is malleable from heating; forming a water tight seal between the top portion to the bottle portion; spin-welding a cap into the top portion, thereby sealing the consumer beverage container; and assembling multiple consumer beverage containers in a uniform layer across a surface of the reservoir, thereby creating a shading structure reducing evaporation and microbial growth.

10. The method of claim 9 including the step of procuring the consumer beverage container from among previously used consumer beverage containers.

11. The method of claim 9 including the step of adding ballast to an interior of the consumer beverage container.

12. The method of claim 9 including the step of obtaining the consumer beverage container made from material safe or drinking water.

13. The method of claim 9 including the step of obtaining the consumer beverage container comprising carbon black.

14. The method of claim 9 including the step of obtaining the consumer beverage container made of a UV resistant material.

15. The method of claim 9 including the step of heat sealing the top portion to the bottom portion.

16. The method of claim 9 including the step of heat sealing the collar to the bottom portion.

17. A reservoir shading structure, comprising: a consumer beverage container made from material safe for drinking water, and having a bottle portion for holding a beverage and a threaded top portion for decanting the beverage; the top portion having a collar; the top portion removed from the bottle portion, inverted, and replaced in the bottle portion, such that the top portion extends into the bottle portion; the top portion hermetically heat sealed to the bottle portion; and a cap spin into the top portion to render the consumer beverage container permanently hermetically sealed; wherein multiple consumer beverage containers placed in a uniform layer across a surface of the reservoir form the shading structure reducing evaporation and microbial growth therein.

18. The structure of claim 17 wherein the collar is heat sealed to the bottle portion.

19. The structure of claim 17 wherein the consumer beverage container comprises carbon black.

20. The structure of claim 17 wherein the consumer beverage container comprises a UV resistant material.

DETAILED DESCRIPTION

(6) The following, description is presented to enable any person skilled in the art to make and use the invention, and is provided n the context of a particular application, and its requirements. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the present invention Thus, the present invention is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed, herein.

(7) Referring to FIG. 1, a preferred embodiment of the present invention is an apparatus and method of protecting open-air reservoirs while eliminating waste caused by discarded consumer beverage containers (CBCs) 10, typically, but not limited to, water and flavored beverage bottles from eight ounces to two liters in size. CBCs 10 are effective as floats when sealed, and although usually constructed using easily bio- or photo-degradable materials. CBCs 10 can be made from a variety of star plastics, including high-density polyethylene.

(8) Referring to FIGS. 2 and 3, a conventional CBC 10 is shown. The CBC 10 comprises a bottle portion 12 for holding water or similar flavored beverage, and a top portion 14 comprising a threaded opening 16 through which the beverage (not shown) is introduced and consumed. The top portion 14 also includes a collar 18. To prepare the CBC 10 for conversion to a reservoir cover, the top portion 14 is removed from the bottom portion 12 along cut line 20 (FIG. 2) just under the collar 18,

(9) Referring to FIG. 4, the top portion 14 with the threaded opening 16 and collar 18 are inverted and pressed with heat into the existing, used (or new) bottle. Since the top portion 14 typically projects from the bottle portion 12, it creates a protruding structure that would interfere with other adjacent CBCs, thereby allowing light to enter the reservoir water, lessening the effectiveness of the cover. With the tap portion 14 inserted into the bottle portion 12 a more rounded profile is created. The top portion 14 is pressed with heat into the bottle portion 12, thereby creating a hermetically sealed structure.

(10) Referring to FIG. 5, once the top portion 14 is severed, inverted, inserted in to the bottle portion 12 and hermetically sealed, as cap 22 is spin welded into the top portion 14, thus hermetically scaling the modified CBC 10. In one embodiment, the cap 22 may be from an identical CBC 10 or from the CBC 10 under modification.

(11) In order to survive continued sun exposure, and to avoid leaching endocrine disruptors such as BPA into the water, CBCs 10 intended for recycling into reservoir covers are made from high density polyethylene (HDPE). Preferably the HDPE contains a carbon black primer and a UV inhibitor. Any additional materials comprising the CBCs 10 should be NSF (National Standards Foundation)/ANSI Rule 61 certified (i.e., safe for drinking water). The cap 22 used to seal each CBC 10 is preferably made of the same or a similar NSF/ANSI Rule 61 compliant material.

(12) In one embodiment sealing the bottle occurs after ballasting the bottle to give it an appropriate balanced weight. The balanced weight allows the CBC 10 to roll and helps prevent microbial and algal growth. By incorporating a permanent spin-welded seal, the lifespan of the reservoir cover is extended considerably. By repurposing consumer beverage bottles as reservoir covers, it is estimated that approximately eighty percent of the fifty million bottles thrown into landfills each year can be repurposed. Since

(13) The foregoing descriptions of embodiments of the present invention have been presented only for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the forms disclosed. Accordingly, many modifications and variations will be apparent to practitioners skilled in the art. Additionally, the above disclosure is not intended to limit the present invention. The scope of the present invention is defined by the appended claims.
