The door 30 may include one or a plurality of hinges 32, or the like, so that the door may be hingedly opened from one side. The hinges 32 may be fastened to the toilet shelter 12 with fasteners, but may also be integrally fastened thereto using a variety of thermoforming or heat lamination techniques. Further, the door 30 may include a handle 34. Again, the handle 34 may be repositionable along the door 30 to meet the particular usage, including any of the portable toilet schematic arrangements shown and described herein.
FIGS. 4 and 5 introduce elements of the interior housing 24 of the lower toilet shelters 12. As shown, each of the units may include a lower holding tank assembly 50. Typically, the holding tank includes a top wall, sidewalls and bottom wall to generally define a closed receptacle to receive and retain waste and chemicals. The lower holding tank may further include a removal port to drain and remove waste. A toilet seat 40 is mounted to the toilet unit 44 which is gravity fed to the holding tank assembly 50. In other examples, a urinal 42 is mounted either to a portion of the toilet unit 44, the base 26 or to the sidewall 20 in fluid communication with the holding tank assembly 50. The base 26 may be constructed of solid plastic and its upper surface may include a non-skid floor 46 as a sanitary top surface. In other examples, a potable water sink may be secured in the interior housing 24 in fluid communication with the holding tank assembly 50.
Any of the portable toilets shown and described herein may be positioned along a generally flat surface for use in a variety of configurations for a portable restroom arrangement. Exemplary positioning includes rows of portable toilets aligned adjacent to one another replicating a ‘six-pack’ drink package design. FIG. 6 introduces one such particular schematic arrangement, wherein the six portable toilets 10a-10f are spaced apart from one another and positioned in two adjacent rows, for instance in three shelters per row. Other examples include fewer or greater than three shelters per row. Each door 30 is facing outward to allow convenient access, while the opposing face 38 of each portable toilets 10a-10f are spaced apart from one another and aligned back-to-back. The result is a unique schematic arrangement of a ‘six-pack’ design. In particular examples, any of the body wrap labels shown and described herein may draw attention to a particular advertising or labeling scheme. This portable toilet schematic may create an aesthetically-pleasing toilet arrangement, wherein patrons may designate the schematic as a landmark, for instance with directions “meet me at the ‘X’ vender six-pack.” Those of ordinary skill in the art having the benefit of this disclosure will recognize other toilet schematics include any variety of arrangements replicating bottle- or can-grouping commercial packaging, including a ‘twelve-pack’, straight line, wine box, fast-food collection or the like.
