  Any of the portable urinals as described above can be used as long as they are in an automobile with sufficient indoor space, but in particular, a container (bottle) type is a user's clothes. The use (addition) of clothing such as trousers and skirts that hides it is difficult or impossible especially for men because of its size. Therefore, it cannot be used easily in places where there is a line of sight of others, such as a sightseeing bus, or in places where the appearance of others is expected even in the outdoors.

  In addition, even if it can be used to add work in a private vehicle that is driven by the user while it is stopped, it is still difficult to urinate without worrying about the eyes of others in the daytime. This is because it is necessary to urinate toward the urine receiving part while holding the portable urinal, and it is necessary to expose the penis if it is a man, and even a woman needs to take a proper posture. Because.

  The invention of the present application was made in view of toilet situations in such driving and outdoor activities, etc., and even if it is urinary in the absence of toilets, it does not bother the eyes of others and is used It is an object of the present invention to provide a portable urinal that can be used without any restriction on the posture of the time.

  A portable urinal according to a first aspect of the present invention for solving the above-described problems is a flexible urine receiving cup, a urine reservoir, and a connection between the urine receptacle cup and the urine reservoir. A urine transfer tube, and a vacuum pump provided to suck the urine discharged to the urine receiving cup through the urine transfer tube and depressurize the urine reservoir for transfer to the urine reservoir. It is characterized by providing.

According to a second aspect of the present invention, in the portable urinal according to the first aspect, the suction port of the decompression pump and the urine storage container are connected by a flexible decompression tube. is there.
The invention according to claim 3 is the portable urinal according to claim 1, wherein the decompression pump is a manual pump.
The invention according to claim 4 is the portable urinal according to claim 1, wherein the decompression pump is an electric pump.

According to a fifth aspect of the present invention, the urine storage container has a lid detachably attached to the top thereof and is attached in a watertight manner. The urine transfer tube and the decompression tube both have their respective ends. A coupling type detachable one-touch joint consisting of a joint attached to the portion and a counterpart joint attached to the lid is connected to the urine storage container. It is a portable urinal of any one of 2-4.
The invention according to claim 6 is provided with a check valve for preventing the urine transferred to the urine storage container from flowing back toward the urine receiving cup. It is a portable urinal of any one of these.

  In the portable urinal of the present invention, the urine receiving cup and the urine reservoir are different from each other through the urine transfer tube. In such a structure, the urine receiving cup constituting the portable urinal is smaller than the entire size of the conventional bottle-type portable urinal in which the urine receiving cup and the urine storage container are integrated. be able to. Therefore, in use, the urine receiving cup and a part of the urine transfer tube connected to the urine receiving cup are put inside clothing (for example, trousers and pants), and then urinated in the urine receiving cup. It is also easy to hold so that For this reason, according to the portable urinal of the present invention, it can be used without worrying about the eyes of others. Then, when it is desired to add the work, the user himself / herself holds the urine receiving cup in this way, and then urinates the urine receiving cup while driving the pump. The urine discharged in this way is transferred to the urine storage container through the urine transfer tube by the suction action of the pump, so that the urine storage container is placed in the back of the body, for example, By placing it in your car, you can use it without worrying about the eyes of others.

  That is, in the present invention, the pressure reducing pump is provided, and urine is transferred (conveyed) to the urine storage container by suction action by driving the pump. Since it can be used without being low, it is very convenient and convenient. If the urine transfer to the urine container depends on gravity drop as in the past, the position of the urine container must be lower than the urine receiving cup so that the portable urinal Since the whole must be maintained, there is a restriction on the posture during use. On the other hand, in the use of the portable urinal of the present invention, even when the user stands up, the urine storage container is attached to the waist of the user, for example, higher than the urine receiving cup as described above. be able to. Similarly, even when used in a car, even when used while sitting on a seat, the urine storage container can be placed on the seat, which is convenient and extremely convenient. The urine transfer tube may have an appropriate length.

  According to a second aspect of the present invention, when the suction port of the decompression pump and the urine storage container are connected by a flexible decompression tube, the decompression pump is connected to the decompression tube. Since the urine storage container can be placed at a position away from the urine storage container through the length of the urine storage container, for example, the urine storage container is held in a waist bag and the decompression pump is You can also keep it in your pocket. Thereby, portability can be improved. The decompression pump is preferably a manual pump as described in claim 3 because it is easy to reduce the size and simplification, but may be an electric pump as described in claim 4. The amount of urination per person is usually about 200 to 500 cc, and the discharge flow rate (5 to 20 cc / sec) is also small. Therefore, such a decompression pump only needs to be able to appropriately reduce (depressurize) the space in the urine storage container to such an extent that such urine can be sucked into the urine storage container. . That is, since this decompression pump may be of such a performance that can smoothly suck and transfer urine, the required amount of exhaustion may be small and the exhaust speed performance may be low. The air pump can be used. Since the urine receiving cup is only an entrance (receiving port) through the urine transfer tube to the urine reservoir, it is sufficient if there is a space where urine does not overflow by driving the decompression pump.

  In addition, as described in claim 5, by connecting the both tubes to the urine reservoir, both tubes can be easily removed in discharging the urine collected in the urine reservoir. Therefore, after use, urine can be easily discarded by bringing the urine storage container with both tubes removed into the toilet. In the present invention, as described in claim 6, it is preferable for safety to provide a check valve for preventing a backflow. In addition, what is necessary is just to provide the attachment position in the appropriate place of the tube for urine transfer.

  In the present invention, the urine receiving cup may be formed into a shape and a structure that can easily receive urine in males and females. The male urine receiving cup has a cylindrical shape or an elbow-shaped cylindrical shape with one end closed, and the end of the urine transfer tube is connected to one end thereof, and the other end side opened is a penis insertion portion. It is good to form so that the cross section (opening cross section) of a cylindrical part may be circular. The urine receiving cup itself may be made of an appropriate material such as resin (hard resin, soft resin) or rubber. When the urine receiving cup is made of a hard resin, it is preferable that a rubber packing having a ring shape is attached to the inner peripheral surface of the opening along the circumferential direction. On the other hand, a urine receiving cup for women has a funnel shape with an oval or oval opening that can be pressed or closely contacted with the genital area including the urethral opening more widely than the left and right sides of the genital area, and is placed at the appropriate position at the bottom. It is advisable to connect the end of the urine transfer tube. In addition, it is good to attach the rubber packing which makes a ring shape along the circumferential direction of this opening to the peripheral part pressed against the said shadow part in this opening.

The typical partial sectional view for explanation which materialized the portable urinal of the present invention (fracture sectional view). The partially broken sectional view for description when the urine container is separated in the portable urinal of FIG. A is a plan view showing another example of a urine receiving cup, and B is a central cross-sectional view of A. FIG.

  Embodiment 1 which embodies the portable urinal according to the present invention will be described with reference to FIGS. However, in this example, it is the portable urinal 100 for men, and the elbow (cylinder) -shaped urine receiving cup 10 having a circular cross section, the cylindrical bottle-shaped urine container 20 and the connection between the two are connected. The flexible urine transfer tube (circular pipe) 30 for feeding (pouring) the urine discharged into the urine receiving cup 10 into the urine storage container 20, and the urine storage container 20 It is composed of a decompression pump 40 and the like that are connected by piping so as to decompress the inside, and all are made of resin.

  The urine receiving cup 10 has a bottomed cylindrical shape in which a cylinder is bent or curved at 90 degrees, and its inner diameter is sized so that a penis can be inserted. A peripheral edge 12 of the opening 11 is formed around the inner peripheral surface thereof. A ring-like rubber packing 14 is attached so that the cushion surface exists along the direction. As a result, the uncomfortable feeling during use (when penis is inserted) is alleviated. However, the urine receiving cup 10 of the portable urinal 100 for men as in this example is easily deformed or flexible. It may be made of rubber or resin. However, it is preferable to have elasticity so that it can be returned to the original shape after being crushed by the user's own hand, for example.

  The urine storage container 20 has a cylindrical bolt shape, and is mainly composed of a container main body 21 and a lid 25 attached to an upper end portion of the urine storage container 20 by a screwing attachment / detachment method. That is, the urine storage container 20 is configured by screwing a female screw 23 formed on the inner peripheral surface of the lid 25 into a male screw 23 formed on the outer peripheral surface of the upper end of the container main body 21. A rubber packing (ring packing) 27 is interposed at the upper end of the container main body 21, and the water tightness (and airtightness) is maintained by compressing the rubber packing 27 by screwing it. The decompression pump 40 is a manual pump in this example, and is a known simple pump that discharges air sucked from the intake port 43 from the exhaust port 45 by repeatedly driving the bellows 42 at the upper end to be pushed down. A simple air pump is used.

  One end 30a of the urine transfer tube 30 is connected to the bottom 16 of the end opposite to the opening 11 of the urine receiving cup 10 to keep it watertight (and airtight), and the other end 30b is connected to the urine storage container. The lid 20 is connected to the lid 25 while maintaining watertightness (and airtightness), and communication between the urine receiving cup 10 and the urine storage container 20 (internal space 20k) is ensured. Further, the other end 50b of the decompression tube 50 having one end 50a connected to the intake port 43 of the decompression pump (manual pump) 40 is connected to the lid 25 of the urine storage container 20 while maintaining airtightness. The inside of the urine storage container 20 can be depressurized by driving the pump 40. The capacity of the urine storage container 20 may be set by adding an appropriate safety factor to the standard urine output for one time. For example, the internal capacity is set to about 1 liter. Moreover, both the tubes 30 and 50 are tubes made of a flexible material such as vinyl, for example, and both have an inner diameter of 5 mm.

  In this example, both the tubes 30 and 50 are connected to the lid 25 at the other ends 30b and 50b by joints 33 and 53 attached to the respective ends and a counterpart joint 35 attached to the lid 25. , 55 are connected via detachable one-touch joints 37, 57 of a coupling type, and one-touch connection (detachment) is achieved. However, the urine transfer tube 30 is a joint attached to the other end 30b of the urine transfer tube 30 with respect to a counterpart joint (female joint) 35 fixed to a 90-degree elbow joint 30e attached to the top of the lid 25. The (male joint) 33 is a one-touch joint 37 that is detachably fitted. Similarly, the decompression tube 50 is a joint attached to the other end 50b of the decompression tube 50 with respect to the counterpart joint (female joint) 55 fixed to the 90-degree elbow joint 50e attached to the upper portion of the lid 25. The (male joint) 53 is a one-touch joint 57 that is detachably fitted. In addition, a urine introduction tube 30g and an air suction tube 50g having appropriate lengths are extended in a hanging manner inside the lid 25 (inside the container main body 21) in both elbow joints 30e and 50e. Further, in the urine storage container 20, a partition plate 28 that divides the two tubes extending in a hanging manner is provided in a hanging manner from the lower surface of the lid 25.

  In this example, when the tubes 30 and 50 are separated from the joint state shown in FIG. 1 (see FIG. 2), they are attached to the joints 33 and 53 attached to the other ends 30b and 50b and the lid 25. The other counterpart joints 35 and 55 each include a mechanism for closing the valve. Therefore, when the tubes 30 and 50 are separated from each joint state in this way, the urine remaining in the tube is set not to leak from the other end 30b of the urine transfer tube 30, and the urine reservoir is set. The urine in the urine storage container 20 is also prevented from leaking from the counterpart joints 35 and 55 attached to the lid 25 of the container 20.

  Thus, in the portable urinal 100 of this example, by driving the decompression pump 40, the air in the interior (space) 20k of the urine storage container 20 is reduced by the decompression tube 50 as indicated by the dashed arrow. The air flows through the exhaust port 45 of the decompression pump 40. Accordingly, as shown in FIG. 1, for example, when water W is injected into the urine receiving cup 10 at a flow rate at the time of urination while being driven, the urine transfer tube 30 is blocked. The inside (space) 20k of the reservoir 20 is rapidly depressurized. As a result, the water W flows through the urine transfer tube 30 as indicated by a solid arrow, passes through, is sucked into the urine storage container 20, and is dropped and collected. In addition, the decompression pump 40 in this example is a manual pump, and a hand-pumped air pump capable of supplying air to, for example, a floating ring which is a seawater bathing equipment is also sufficient. What is necessary is just to connect the air suction port (suction port) 43 side of the pump to the urine storage container 20 through the decompression tube 50. That is, since the amount and flow rate of one urine to be suctioned by the portable urinal 100 are very small as described above, it is sufficient to use a simple air pump. In this example, a manual pump is used. However, even when an electric pump is used, it is sufficient to use a dry battery type small motor.

  Next, a method (example) of using the above-described portable urinal 100 will be described. When urinating or preparing for urination, the user puts the urine receiving cup 10 into clothes (for example, trousers), and inserts the penis into the opening 11 of the urine receiving cup 10 as indicated by the arrow A1. Then, the urine receiving cup 10 is held between the groins by closing both legs as appropriate. At this time, if the boxer type underpants are attached, the urine receiving cup 10 can be stably held on the body in the pants.

  On the other hand, the urine transfer tube 30 is taken out from the upper part of the trousers along the lower abdomen, for example. On the other hand, the urine storage container 20 to which the tube 30 is connected is accommodated in the waist bag together with the decompression pump 40 in advance, for example, and this waist bag is attached to its own waist. Then, urination is started while driving the pump 40 by itself. By starting the urination, urine is discharged into the urine receiving cup 10, but at the same time, the inside of the urine transfer tube 30 is blocked with urine, and the internal space 20k of the urine storage container 20 is rapidly decompressed, so that the urine is discharged. The produced urine flows (transfers) into the urine storage container 20 through the urine transfer tube 30. Thus, the user can use the vacuum pump 40 until the end of urination.

  As described above, in such use, the urine receiving cup 10 is not seen by others due to the appearance. For this reason, even in a sightseeing bus or outdoors, it is possible to urinate without worrying about the eyes of others as compared with the use in a conventional portable urinal. That is, since the urine receiving cup 10 is merely an accepting port for the urine storage container 20, the urine receiving cup 10 itself is not as large as a portable urinal integrated with a conventional urine storage container. Because there is no, it can be held inside the clothes. And the urine storage container 20 is accommodated in the waist bag, etc., and it does not cause the discomfort on an external appearance. Therefore, you can use it with confidence. Thus, by carrying such a portable urinal 100, even a frequent urine person can enjoy a vacation without hesitation.

  Also, for example, when taking measures against urination due to urinary movement while moving in a private car, the car is stopped in place, the urine receiving cup 10 is taken out, and the urine receiving cup 10 between its own crotch is the same as described above in the trousers. Hold. On the other hand, the urine storage container 20 to which the urine transfer tube 30 is connected may be placed on the floor in the vehicle, but as described above, the tube 30 is taken out along the lower abdomen, for example, a sheet. Can also be used in That is, the discharged urine is not transferred to the urine storage container by a natural drop method by mere gravity as in the prior art, but is transferred by suction by decompression. Therefore, the urine storage container 20 is urinated for urination. This is because it can be held higher than the receiving cup 10. Thereby, especially in the frequent urination person, if the portable urinal 100 of this example is mounted in a personal car, it can be relieved even if it encounters a traffic jam.

  After the addition, the tubes 30 and 50 are removed from the lid 25 as described above at the one-touch joints 37 and 57 at the ends, and the urine storage container 20 with the lid 25 is held and the toilet is placed in a proper place. The urine collected by unscrewing the screw 25 and then collecting the urine collected in the toilet bowl may be disposed next. In this case, as described above, in this example, when both tubes 30 and 50 are removed, the joints 33 and 53 of the ends 30b and 50b and the counterpart joints 35 and 55 on the lid 25 side are also closed. Since the mechanism is included, there is no urine leakage from each joint in the process of transporting the urine container 20 to the toilet. As a result, it can be used and processed without worrying about soiling the surroundings.

  In this example, the decompression pump 40 has its suction port 43 connected to the urine storage container 20 via the decompression tube 50, but the suction port 43 is directly connected to the urine storage container 20 without using such a tube. , Piping, connection. In the case where the size is reduced as in the case of the electric pump, by doing so, the urine storage container 20 with the pump can be obtained, and the size can be further reduced. On the other hand, as in this example, when the decompression pump 40 is connected via the decompression tube 50, the holding and installation position of the decompression pump 40 can be selected within the range of the length of the tube, which is convenient. As shown in FIG. 1, urine transferred toward the urine storage container 20 at an appropriate position of the urine transfer tube 30, particularly, a position (part) close to the urine receiver cup 10 is transferred to the urine receiver cup 10. It is advisable to provide a check valve Cv that prevents backflow toward the front.

  In the above example, since the urine receiving cup 10 is for a male, it has a cylindrical shape. However, in the case of a female, the urine leaks or overflows depending on the body shape in the vicinity including the urethral opening. It is good to make it the funnel shape which has the shape of the opening which is easy to receive urine without doing. FIG. 3 shows an example thereof. The urine receiving cup 10b of the present example has a funnel with an opening end 12 forming an ellipse or an ellipse so that the opening 11 is long on the left and right in the figure. It is formed to have a shape, and one end 30a of the urine transfer tube 30 is connected to the bottom 16b.

  The portable urinal according to the present invention is not limited to the above-described embodiments and the like, and can be modified and embodied as appropriate without departing from the scope of the invention. As described above, the portable urinal according to the present invention requires the holding of the urine receiving cup and the driving of the decompression pump in its use. For this purpose, the hand can be moved freely. I can do it. Therefore, the portable urinal according to the present invention can be used not only as a countermeasure against a toilet during movement in a vehicle such as an automobile or during outdoor activities, but also, for example, even if it is a person with difficulty walking or a bedridden person. Even if there is no assistant (assistant), the person who can move can also add himself / herself, which is also effective as a countermeasure against urination of such person.
