BACKGROUND OF THE INVENTION  
       [0001]     1. Technical Field  
         [0002]     The present invention is related to portable sanitary sheet for seated toilet bowl that is available for carrying in the pocket or bag and can be used simply by spreading over seat of seated toilet bowl in the rest room. Besides a great deal of advantages of portability, the invention represents more convenient and sanitary properties in utilizing than conventional sanitary sheet for seated toilet bowl.  
         [0003]     2. Description of the Prior Art  
         [0004]     Except for the case of making a private use of independent personal seated toilet bowl, single seated toilet bowl needs to be used for the people and in this case sanitary problem takes place above all. In other words, when a seated toilet bowl is once used there arises a good possibility that preoccupying person leaves dirts or other foreign substances on seat ( 5 ) making it much unsanitary and causing the other persons to feel uncomfortable in utilizing seat and so it is the most common to use seat either by clearing urine or dirts left on seat ( 5 ) with tissue paper or newspaper or by covering again tissue paper or newspaper on seat after clearing urine or dirts. However these methods are quite inconvenient,  
         [0005]     uncomfortable, unsanitary, and asking too much excessive consumption of tissue paper leading to uneconomical problem.  
         [0006]     As a resolution to the above mentioned problem, sanitary sheet has once been introduced to attach on seat dozens of sheet (made of paper or film) whose reverse side is coated with sticky resin and to utilize in separate piece in need. But this product has been found to have problem because it&#39;s inconvenient in use getting wet with rain or detergent when cleaning, unsanitary owing to the possibility of contamination to urine or excrement and much likely to be missing. In addition, due to somewhat high manufacturing cost and difficult process technologies related, it&#39;s not commonly applied at present.  
         [0007]     For this reason, another type of product has also been introduced to fold in half and pile in dozens layer sanitary sheets fabricated as  FIGS. 4, 4   a  inside rectangular-shaped box attached to the wall of the restroom, and take out by piece to use. This can not be used for portable purpose but for the restroom purpose only and therefore it should be noted that the intention of the product is different from that of the present invention.  
         [0008]     Firstly, it&#39;s needed to look over conventional sanitary sheet as  FIG. 4 . The sheet is shaped to make it enable to pull out the center part of the paper ( 32 ) by forming cutting line ( 31 ) to the oval type of hole in the center except for the restricted area of the rear part. In order to use this right, it is required to spread main body ( 10 ), pull out cutting line ( 31 ) by using both hands, remove the center part of the paper ( 32 ) and then put main body ( 30 ) on seat to use. But in different way it is also available to remove the  
         [0009]     center part of the paper ( 32 ) not completely separated from main body ( 30 ) but partially separated by pulling out cutting line ( 31 ) only. In this case the center part of the paper ( 32 ) is hanging on main body ( 30 ) downwards inside seat. In the same way  FIG. 4   a  is designed to cut ahead the whole center of main body ( 40 ) with same shape as in  FIG. 4  except for the partial area of the rear part on which the center part of the paper ( 42 ) is hanging. Accordingly when spreaded over seat, the center part of the paper ( 42 ) is hanging on main body ( 40 ) downwards inside seat.  
         [0010]     By the way, all these methods are troublesome as the center part of the paper ( 32 ,  42 ) contacts with the water inside seat. Because of this, the towards main body ( 30 ,  40 ) and reaches up to main body ( 30 ,  40 ) thus leading to the uncomfortable and unsanitary result. The users then find the way to completely cut the center part of the paper ( 32 ,  42 ) off main body ( 30 ,  40 ) to use main body ( 30 ,  40 ) with hole only. Therefore it&#39;s quite natural that it takes a lot of time and causes inconvenience to use the sheet. The product in  FIG. 4  with cutting line ( 31 ) takes more time than that in  FIG. 4   a.    
         [0011]     Moreover, conventional type of sanitary sheet as in  FIG. 4 ,  FIG. 4   a  is shorter in width than in length and likely causes fingers to touch the surface of seat when griping both sides of main body ( 30 ,  40 ) to place on seat ( 5 ) and is therefore unsanitary. In the case of using the restroom placed in travelling devices in movement (vehicle, airplane, train) the problem is getting worse as user find it so difficult to stand in balance and much inconvenient  
         [0012]     to match main body ( 30 ,  40 ) straight to the center of seat.  
         [0013]     Further, conventional type of product described makes old persons, patients and children find it much inconvenient to use.  
       BRIEF SUMMARY OF THE INVENTION  
       [0014]     The invention aims at providing a sanitary sheet for seated toilet bowl which can be carried for easy use in need all the time and is more sanitary.  
         [0015]     The detailed composition of the present invention features main body ( 10 ) which when placed on seat ( 5 ) with it&#39;s width (a) &amp; length (b) forming rectangular has hand grip ( 11 )( 11   a ) protruded to it&#39;s both sides, center hole ( 12 ) with at least more than 1 support part ( 13 ) and a sticky resin-coated part ( 14 ) symmetrically forming under limited area of main body ( 10 ) and the center of support part ( 13 ) with cutting line.  
         [0016]     The present invention also features main body ( 10 ) which when placed on seat ( 5 ) with it&#39;s width (a) &amp; length (b) forming rectangular has hand grip ( 11 )( 11   a ) protruded to it&#39;s both sides, center hole ( 12 ) with at least more than 1 support part ( 13 ) and is folded in small size and inserted into carryable vinyl pack ( 50 ).

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0022]     To begin with, the 1st application example of the invention shows main body ( 10 ) which when placed on seat ( 5 ) with it&#39;s width (a) &amp; length (b) forming rectangular as  FIG. 2  has hand grip ( 11 )( 11   a ) protruded to the direction of both sides of seat ( 5 ), center hole ( 12 ) with at least more than 1 support part ( 13 ) connected to main body ( 10 ). Nextly the 2nd application example of the invention shows sticky resin-coated part ( 14 ) symmetrically forming at both sides of center hole ( 12 ) which is a part of above-mentioned main body ( 10 ).  
         [0023]     In the 2nd application example, sticky resin-coated part ( 14 ) has only to be sticky to an extent that main body ( 10 ) manages to keep it&#39;s position on the surface of seat. In this case it might be more convenient in use to have sticky resin-coated part ( 14 ) colored and print a explanatory note on the part of main body ( 10 ) saying “please have sticky resin-coated part contact with seat”.  
         [0024]     Nextly, the width ( 1 ) of hand grip ( 11 )( 11   a ) protruded to both sides when placing main body ( 10 ) on the center of seat needs to be 20 mm minimum and 300 mm maximum. As a result of the application examples of the invention, 50 mm˜100 mm has been found to be proper for the above width ( 1 ). As a major part of the invention, the hand grip ( 11 )( 11   a ) is a technology that has never been applied to conventional type of sanitary sheet. As being extended long to the width direction hand grip makes it quite easier to spread by hand main body ( 10 ) and place in position on seat ( 5 ) and much convenient to use in the restroom placed in travelling devices in movement as well.  
         [0025]     Explaining again, in the 1st application example gripping hand grip ( 11 )( 11   a ), spreading main body ( 10 ) to both sides, and matching the hole ( 12 ) of the invention to the center hole of seat ( 5 ) are needed for use, in the 2nd application example gripping hand grip ( 11 )( 11   a ), spreading main body ( 10 ) to both sides, and matching the hole ( 12 ) of the invention to the center hole of seat ( 5 ) and then slightly pressing with hand grip ( 11 )( 11   a ) facing the ground are followed to have sticky resin-coated part ( 14 ) stick to the surface of seat and place in position afterwards. In the next when a user sits on seat ( 5 ), a support part ( 13 ) formed in the hole ( 12 ) is naturally cut by the weight of the user and therefore no troubles are raised in evacuating excrement and urine.  
         [0026]     As shown above adopting the present invention fingers are kept out of the contact with seat ( 5 ) thus sanitary and it&#39;s quite convenient and sanitary to separate the whole main body ( 10 ) from seat ( 5 ) by pulling hand grip ( 11 )( 11   a ) hanging down to both sides of seat ( 5 ). Therefore hand grip ( 11 )( 11   a ) is sanitary, convenient and safe in both using the invention for evacuating and removing the invention from seat ( 5 ) after evacuating and so enables old persons, patients and children to use easily.  
         [0027]     On the other hand, it has been noticed in the test that it is so inconvenient in use to spread main body ( 10 ) by pulling hand grip ( 11 )( 11   a ) and place firm on seat ( 5 ) as specified earlier but without support part ( 13 ) of the hole ( 12 ) because the shape of the hole ( 12 ) is distorted to the direction of both sides or further torn due to the tension imposed. Accordingly it has come to an conclusion that it is more desirable to apply at least more than 1 support part ( 13 ) to the direction of both sides as the invention. By the way, it&#39;s better to keep the width of support part ( 13 ) less than 20 mm and is also available to adopt less than 10 mm in 2 lows however these can be freely adjustable. Additionally cutting line can be applied in the center of support part ( 13 ) to make it easier to cut support part ( 13 ) by the weight of users when placing main body ( 10 ) on seat ( 5 ).  
         [0028]     And as described earlier, support part ( 13 ) which has been cut by the weight of a user has it&#39;s center area mostly cut and therefore differently from the conventional products the cut length is getting shorter. Accordingly a support part ( 13 ) whose center area keeps out of contact with the water inside seat, makes it available to avoid seeing it soak to the water inside seat and therefore takes away uneasiness owing to unsanity.  
         [0029]     The invention suggested so far can be used for portable purpose after inserting into vinyl pack ( 50 ) by folding main body ( 10 ) in two and repeating the same process until it gets smaller to around 10 cm in width and 5 cm in length as  FIG. 3 . Of course, it is quite natural that the invention can be inserted in the box attached to the wall of the restroom to pull out by piece for use and in this case it can be folded in larger size (ie: the width=30 cm, the length=20 cm).  
         [0030]     As for raw material for the invention, it is desirable to select very thin paper which is well soluble in water or water based film, but on the other hand it might also be available to select various types of materials because materials which are not soluble in water can be reused once collected into the trash can. And further it would be much better to apply the anti-bacterial &amp; perfuming treatment to main body ( 10 ) but perfuming treatment is not necessarily required. Additionally it might also be much better to make main body ( 10 ) of the invention in various colors, print on main body ( 10 ) advertisement or public propaganda.  
         [0031]     The invention specified above is contrived to measure the width (a) longer than the length (b) and form support part ( 13 ) in the center hole ( 12 ) and is therefore convenient, safe and sanitary in use compared with conventional type of product. Moreover it can be used conveniently &amp; safely in the restroom placed in travelling devices in movement (vehicle, airplane, train) as well and can also be used promptly and conveniently by anyone including young and old, men and women all alike and patients.
