Tank compartment 86 receives and holds the liquid urine waste. Tank compartment 86 has therein an air space (not shown) above the liquid urine waste. It will be understood that odor-causing vapor released from the liquid urine waste into the air space of tank 86 can be a source of objectionable urine waste odor to persons using portable urinal 10, unless such odor-causing vapor is prevented from contacting the olfactory senses of such persons. It will be understood that reducing the amount or concentration of odor-causing vapor released through the first mouth 492 into undesired contact with the olfactory senses of such persons can be effective to reduce or avoid discomfort experienced by persons using the first station 22 and portable urinal 10. The first primary odor prevention device 752 is functional to reduce the amount of odor-causing vapor released from the first urine receptacle 482 out through the first mouth 492 into the first personal space 301 for undesired contact with the olfactory senses of persons using the first station 22 and portable urinal 10. The first primary odor prevention device 752 thus is functional to reduce or avoid olfactory discomfort experienced by persons using the first station 22 and portable urinal 10.

As shown in FIG. 8, the first urine receptacle 482 includes a continuous outer lip 762. The outer lip 762 of first urine receptacle 482 defines the first mouth 494. First mouth 494 includes an open space or first mouth opening in open communication with air in the first personal space 301 of first station 22 for receiving a stream of urine which passes therethrough upon being released from the urinary organ of the first person during an act of urination. First urine receptacle 482 includes a receiver sidewall 764. The receiver sidewall 764 is generally continuous and terminates at outer lip 762. The receiver sidewall 764 tapers inward from the outer lip 762 defining first mouth 494. The receiver sidewall 764 is in open communication with a receiver outlet 766. Receiver outlet 766 is spaced from the outer lip 762 and from first mouth 494 defined thereby. Receiver outlet 766 is located at a vertical position below first mouth 494 to enable gravity flow of liquid urine waste impinging upon receiver sidewall 764 along a downward path defined by the receiver sidewall 764 through the receiver outlet 766 into a urine conduit (not shown). It will be understood that the receiver sidewall 764 has a negative or fade-away angle intermediate the outer lip 762 and receiver outlet 766 to prevent urine from back splashing on the user during release of a urine stream. It will be understood that the urine conduit (not shown) is formed by suitable tubing in communication between the receiver outlet 766 and tank compartment 86 for liquid urine waste to flow therethrough. In the specific embodiment illustrated, receiver outlet 766 and the urine conduit (not shown) are positioned above tank compartment 86 to cause gravity flow of liquid urine waste downward through the intermediate urine conduit (not shown) into the tank compartment 86. Returning to FIG. 8, receiver sidewall 764 defines a funnel structure 768 having wide upper section 769 and a narrow neck 770 below the upper section 769 and opposite the first mouth 494. The upper section 769 has an upper section cross-sectional area. The neck 770 has a neck cross-sectional area which is less than the upper section cross-sectional area. The first primary odor prevention device 752 includes the receiver outlet 766 being located at a bottom of the neck 770 in spaced relation to upper section 769.

According to embodiments, a portable urinal is constructed of any suitable material. In embodiments illustrated herein, for example, a portable urinal is formed of any suitable material which provides sufficient structural strength and durability. In the specific embodiment illustrated in FIG. 1, portable urinal 10, for example, is formed of thermoplastic material. It will be understood that any suitable thermoplastic material can be used. In the specific embodiment illustrated in FIG. 1, the thermoplastic material is polyethylene material. According to embodiments, the polyethylene material can withstand rain, wind, snow and heat without undergoing substantial change of shape or dimensions and without failure during use. It will be understood that, according to embodiments, thermoplastic material when used can be constructed in any suitable manner. For example, thermoplastic material forming portable urinal 10, or components thereof, can be suitably thermoformed, vacuum formed, rotationally molded, or blow molded. According to the specific embodiment illustrated in FIG. 1, the exterior movable doors, fixed exterior walls, interior privacy partitions and roof are vacuum molded. According to embodiments, a portable urinal has an outside diameter or width of about 54 inches. According to one specific embodiment (not shown), a portable urinal has an outside diameter or width of about 45 inches and thus fits two abreast in a standard ISO shipping container having a nominal width of about 8 feet. According to embodiments, a portable urinal is provided which is sufficiently tall to accommodate a typical user having an individual height of about 6 feet. For example, a portable urinal 10 is provided according to embodiments which is approximately about 85 inches in overall height and about 54 inches in diameter and is suitably sized to accommodate three simultaneous users each having an individual height of about 6 feet without bending down to fit beneath the roof. According to embodiments, a portable urinal 10 has a load rating sufficient to accommodate three simultaneous users each having a weight of about 300 pounds and waste urine in the tank compartment 86 having an additional weight of about 800 pounds. According to embodiments, the movable base 18 can have a height or spacing between the bottom 76 and floor 110 which is in the range of, for example, about 2 inches to about 4 inches. It will be understood that any desired height or spacing between bottom 76 and floor 110 can be provided without departing from embodiments. It will be understood that portable urinal 10 such as, for example, movable base 18 for example, can include separate support members such as wood or steel members (not shown) as desired or necessary to provide structural support without utilizing excessive material. According to embodiments, each station 14 can include a molded shelf (not shown) which is suitable to accommodate an item such as a beverage can. According to embodiments, tank compartment 86 has any desired capacity. In the specific embodiment illustrated, tank compartment 86 has a capacity of about 120 gallons. It will be understood that tank compartment 86 can be vented in any suitable manner. It will be understood that each urine receptacle 90 can include a screen which is suitable to retain foreign objects in the urine receptacle 90 and to prevent such foreign objects such as, for example, cigarette butts, from entering the primary odor prevention device 750, a drain line (not shown) from the primary odor prevention device 750 to tank compartment 86, or the tank compartment 86.

It will be understood that portable urinal 10 includes a tank compartment 86 having therein no added or supplemental chemical agent. Thus tank compartment 86 of portable urinal 86 contains only liquid urine waste and air space above the liquid urine waste. It will be understood that portable urinal 10 can, if desired, include an added or supplemental chemical agent in the liquid urine waste. Such a chemical agent can be in any desired form such as, for example, liquid, solid, slurry, suspension or gas. For example, tank compartment 86 can include therein a liquid admixture of chemicals commonly found in portable toilets. Such mixture of chemicals can be identified, for example, as “a blue water” mixture. It will also be understood that tank compartment 86 has a tank compartment upper outlet 780 (FIG. 13). The tank compartment upper outlet 780 is selectively operable to provide access to tank compartment 86 by an external service hose (not shown). The external service hose is operable to pump the liquid urine waste from the tank compartment 86 into a suitable disposal vessel (not shown). It will also be understood that tank compartment 86 includes a tank compartment sanitary outlet 784 (FIG. 1). The tank compartment sanitary outlet 784 is selectively operable to be connected to an external sanitary pipe (not shown).
