Title: Utility bag that can be unfolded

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     Design of a utility bag including a four-fold piece and two sidings, such that when the bag is folded up, by drawing the correspondingly positioned zipper; a bag is formed, to utilize the bag with a hanger; an extension hanging pouch is attached to the first link element for interconnected application. 
     2. Description of the Prior Art 
     Conventional bags come in many varieties, and basically they are executed to have two grips each attached to the top of the bag. Structurally, such a utility bag has a zipper on top of the pouch, or else, in the form of a zipper-bound raise lid which, once raised open, makes possible the loading of objects by way of the opening, or conversely the withdrawing of objects placed therein. The greatest disadvantage with such design is that it leaves little chances of variation, for example, when one brings a few bottles or containers containing cosmetic items for travel, these bottles and containers, that are randomly positioned, may collide with each other when the bag moves is moved. Further, when one needs to use such bottles and containers in, i.e., a hotel, one needs to take them out from the bag one by one, at least until one finds the desired article which is time consuming, and when leaving the hotel the user needs to put the desired articles into the bag. 
     SUMMARY OF THE INVENTION 
     The primary object of the invention, therefore, is to provide the design for a utility bag which can be fully expanded and can be used for hanging applications. The invention utility bag includes: a bag body and an extension hanging pouch; the body is composed of four folds and two sidings which are deployed on both sides of the fourth fold; the four folds will form a pouch with sidings on both sides once the sealing zipper is drawn to closure. On top of the first fold is furnished a hanging hook which, together with a first coupling element furnished on a chosen spot inside the fourth fold, which makes possible the first coupling element being abutted upon an extension hanging pouch for series application once the body which is fully developed is meant for use in a pendent, hanging position.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIG. 1, it is seen that the invention of a utility bag for hanging application comprises essentially a body  1  and an extension pouch  2 , whereof 
     The body  1 , as shown in FIG.  3  and FIG. 4, is composed of a four-fold piece  11  and two sidings  12  which are to be coupled to both sides of the fourth fold  114 , the first three fold pieces  111 ,  112  and  113  each has zipper  115  on the outer rim, on the extension of the two siding  12  circumferentially to the tail side of the fourth fold  114  are provided a symmetrical zipper  121 , so that by interactive drawing of zipper  115  with zipper  121 , the first three fold pieces  11   1 ,  112 ,  113  may form a pouch abiding by the contour of both sidings  12 , with the first fold piece  111  and the third fold piece  113  being respectively the frontal boarding and the rear boarding of the pouch, on top of the first fold piece  111  is provided a hanging hook  13 , while the second fold piece  112  is located on top of the pouch and complete with a raise lid  14  on the center, on a chosen quarter of the interior of the fourth fold piece  114  is provided a first coupling element  15 ; and the interior of the fourth fold piece  114  and that of the two sidings  12  accommodate sewing to form a container pouch  116  which is made of web texture or tape; 
     The extension pouch  2 , as shown in FIG. 4, is an appendant pouch additional to the bag body  1 , on top of the extension pouch  2  may bear a second coupling element  21  by means of which intercoupling is made possible with the first coupling element  15  on the body  1 , on one side of said second coupling element  21  is equipped a container bag  22  of which the material is web texture or tape, a lug  23  in addition is provided centrally on top of the extension pouch  2 ; 
     Structured accordingly, the bag may serve the purpose of a common bag by opening the raise lid  14  regularly, like what is shown in FIG. 2, while in special occasion or to meet special needs, the closure state of zipper  115  with zipper  121  may be defeated so that the bag may present itself in a fully developed state, whereby hanging is executed by means of the hanging hook  13  on top of the body  1 , and that achieving the utmost exploitation of a bag in all its possibilities, in that mode, objects being carried in person may be securely placed into the container bag  16  of the body  1  to facilitate withdrawal for use later on, the extension pouch  2  may be bound to the first coupling element  15  by means of the second coupling element  21  on top, so that the body  1  of the bag may be suitably interconnected in series with the extension pouch  2  for use. 
     Also, by the design of the invention the extension pouch  2  may be prosecuted in specific pattern pursuant to specific user&#39;s needs, more specifically, the second link element  21  may be interconnected with the first link element  15  on the body  1  in a mutually serially connected utility mode, or else in a separately handing utility mode. Where the separate hanging utility mode is the case, the hanging is procured in position with respect to the lug  23  on top of the extension pouch  2 , by then, the user may elect a utility mode that best suits his needs to make use of the extension pouch  2 , thereby fulfilling its versatility in scope of applications. 
     Next, as shown in FIG.  4  and FIG. 5, execution as to interactive coupling of the first link element  15  on the body  1  with the second link element  21  on the extension pouch  2  may be either in terms of zipper chain or button clasping technique, or otherwise. It is to be noted that variants, replacements executed using the know-how and technique taught in this invention, to the extent not departing from the realizable results, shall be deemed covered in the scope of claims.
