Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to large flat water storage containers or the like and, in particular, discloses a novel form of thermal mass panel having advertising formed therein and a novel affixing method. 
       BACKGROUND 
       [0002]    Large scale fluid storage have become increasingly popular in dry climatic regions for the storage of significant volumes of fluids for later use in accordance with requirements such as for gardens, drinking and other household water usages. A number of these storage devices have a substantially elongated structure and have been utilized to form walls or the like. 
         [0003]    As the storage containers scale in size, often they are constructed in a long thin modular form which is often aesthetically pleasing form for placement along a wall. Unfortunately, long large thin modular volumes full of water pose a dangerous hazard if they are not firmly affixed to a wall or supporting structure. A toppling water containing vessel might crush anything in its toppling path.

     DETAILED DESCRIPTION 
       [0020]    In the preferred embodiment there is provided a flat sided enclosed moulded vessel with signage configured so that the walls of the shapes, letters or numbers form the internal bracing of the two major walls of the vessel, such that any liquid contained within the vessel can flow freely without pooling when the tank is stood on any of its surfaces. The moulded flat sided vessel has multiple functions of holding water and providing signage, and is configured such that the signage configuration is an integral part of the water holding structure. Additionally, the signage structures can be used for affixing the vessel to a supporting structure. 
         [0021]    Turning initially to  FIG. 1 , there is illustrated a plan view of an example water vessel  1  which can be formed by rotational moulding of a corresponding mould. The vessel  1  includes a series of apertures e.g  2 ,  3 ,  5 ,  9  wherein the apertures form two functions of providing structural support to the walls of the vessel and an information or advertising carrying capability. In the present case the apertures include circles  5 ,  9 , stars  2  and the letters USA. 
         [0022]    Turning to  FIG. 2 , there is illustrated a sectional view of the vessel through the line A-A of  FIG. 1 . The vessel is primarily formed from two walls  7 ,  8 , with water being held there between. The apertures e.g.  3 ,  5  provide for structural support bracing the walls  7 , 8 . 
         [0023]      FIG. 3  illustrates a further sectional view through the line B-B of  FIG. 1 . 
         [0024]    Ideally, the apertures are further structured such that, whilst information is made available by means of the apertures, no cavities exist for water to collect or “pool” and be held in the cavity. For example, in  FIG. 1 , the letters “U” and “S” have been formed from constituent parts such that water under the influence of gravity, will flow out of the space between the two arms of the “U” and the bottom of the “S” structure. 
         [0025]    Further, the vessel can be can be mounted with its large flat side parallel to a vertical, horizontal or angled surface or structure via the configured walled openings in its wall surfaces. 
         [0026]    It can be seen that the vessel uses cutouts of letters, numbers or shapes to give it strength and hold its shape when full. The letters, numbers or shapes are so configured that the negative and positive walls formed do not hold water in their curves or recesses but allow water to flow freely around the internal volume. The letters and numbers can include ABCDEFGHIJKLMNOPQRSTUVWXYZ AND 1234567890 and the shapes can including a circle and a star. 
         [0027]    Further, the vessel  1  can be readily stacked horizontally or vertically on a similar vessel without distortion. The vessel can further have hose interconnects at the top and bottom to provide for fluid flow on demand both into an out of the vessel in accordance with the normal requirements for fluid storage vessels of this type. Multiple vessels can be interconnected along side one another at their base thereby allowing water to equalise between vessels as a single volume. 
         [0028]    Ideally, a number of the apertures, e.g. the apertures  5 , 9  are sized so as to provide for an affixing means for the flat walled structure to a fixture. In the preferred embodiment, a series of through apertures are also placed in the flat walled structure to provide structural support for the structure. 
         [0029]    In the preferred embodiment a plate, spring screw and bolting mechanism is used in conjunction with the aperture to affix the tank to a wall or the like. 
         [0030]      FIG. 4  illustrates the affixing mechanism in its components parts which can include a screw bolt  10 , a spring nut  11  and a flat plate washer  12  dimensioned to fit the size of the hole. The screw bolt is inserted though the aperture in the flat plate washer and through a wall fixture and spring bolt  11  utilised to hold the screw in place. 
         [0031]    Examples of the affixing process will now be described initially with reference to  FIG. 5  which illustrates a simple sectional view of the tank  40  having a series of circular holes  45 ,  46  formed there through, the holes being similar to the holes  5 ,  9  of the arrangement of  FIG. 1 . A first hole  42  has a screw  10 , flat washer  12  and retaining bolt  11  assembled therein so as to fix the tank  40  to wall  44 . A second further retaining unit including flat washer  50 , bolt  51  and nut  52  are shown before assembly. 
         [0032]    By utilising the retaining arrangement to fix the tank to a wall thorough the aperture in the tank, a compact and aethetically pleasing affixing mechanism is provided. 
         [0033]    The tank may be affixed in various orientations. For example,  FIG. 6  illustrates the tank being affixed on a slant, with the contained water able to flow freely without pooling. 
         [0034]    The affixing mechanism can lend itself to more complex and aethetically pleasing results. For example, as illustrated in  FIG. 7 , the fixing mechanism can be used to affix a flat walled tank  70  between two other walls  71 ,  72 , thereby providing a simple mechanism for hiding the tank if required) in a walled structure.  FIG. 8  illustrates a sectional view through the arrangement of  FIG. 7  clearly illustrating the three walls  70 ,  71 ,  72  and the fixing bolt  74 , flat washer  76  and screw bolt  75 .  FIG. 9  shows a further sectional view in an assembled form of the three walled structure. 
         [0035]    It can be seen the preferred embodiments provide a compact affixing mechanism for affixing a water tank to a structure in an aesthetically pleasing manner such the tank is also firmly and safely affixed to a structure. 
         [0036]    Although the invention has been described with reference to specific examples it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
