DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Before the present invention is described in greater detail, it should be noted that the similar elements are denoted by the same reference numerals throughout the disclosure.
Referring to FIG. 2, a portable bag 2 of the first preferred embodiment comprises a bag body 21 with an interior space 214 defined therein, a zipper 22 disposed on the bag body 21, and a strap 23 attached to the bag body 21; wherein, the bag body 21 comprises an opening 215 for aiding the interior space 214 in communicating with the outside; further, a plurality of storage pockets 28 and inner compartments 27 are disposed within the interior space 214 of the bag body 21 for regularly placing personal articles therein. Additionally, the zipper 22 includes a zipper track 221 arranged around an outer circumference of the opening 215 and a first zipper tab 222 disposed thereon for sliding along the zipper track 221; an interlocking portion 2211 and a detaching portion 2212 are adjusted by the movement of the first zipper tab 222 along the zipper track 221.
Still further, the strap 23 consists of a fixed portion 231 and a strap loop 232 opposite thereto; wherein, the fixed portion 231 is attached to one side of the bag body 21, in the proximity of the detaching portion 2212; a blocking portion 25 is coupled to the strap loop 232, which can be optionally arranged as a plurality of keys as shown in FIGS. 2 and 4 or as a decoration with various shapes, such as with a tulip shape shown in FIG. 3, and the arrangement of the keys is adopted in this preferred embodiment. Furthermore, the outer diameter of the blocking portion 25 is larger than a dimension of the detaching portion 2212 while drawing the first zipper tab 222 together, whereby the blocking portion 25 is able to be inserted and fixed into the interior space 214.
Referring to FIG. 2, while in use, the personal articles are placed into the interior space 214 of the bag body 21 by drawing the zipper 22 apart; subsequently accompanying with FIG. 4, the blocking portion 25 is inserted into the opening 215 and further the zipper 22 are interlocked so as to aid the blocking portion 25 to be blocked therein by the smaller dimension of the detaching portion 2212 while drawing the first zipper tab 222 together. In this manner, the strap 23 exposed out of the bag 2 can be held in the wrist, and the blocking portion 25 can also be pulled out through slightly drawing the zipper 22 apart, thereby increasing the convenience of use. Accordingly, referring to FIG. 5, the strap 23 is permitted being entirely inserted into the interior space 214, whereby the strap 23 is hidden therein and the bag 2 can be simply held by hand.
Referring to FIG. 6, a portable bag 2 of the third preferred embodiment comprises the similar elements, operations and function as the first preferred embodiment. Differently, a fixed portion 231 of the strap 23 is attached to one side of the bag body 21, in the proximity of the interlocking portion 2211. While drawing the zipper 22 together, the blocking portion 25 is inserted into the interior space 214 and is blocked by the detaching portion 2212, thus the strap 23 is attached to both sides of the bag body 21 to form as a bag with a shoulder strap. Additionally, the blocking portion 25 comprises a plurality of keys 251 and a decoration with various shapes 252 for enclosing the keys 251, so as to protect the bags 2 against the sharpness of the keys 251. The decoration 252 can also be withdrawn while using the keys 251.
Referring to FIG. 7, a portable bag 2 of a fourth preferred embodiment comprises the similar elements, operations and function as the first preferred embodiment. Particularly, the opening 215 is disposed around an outer circumference of the bag body 21, and the zipper track 221 is arranged along the opening 215; a second zipper tab 223 is additionally disposed on the zipper track 221, opposite to the first zipper tab 222. Further accompanying with FIG. 8, while in use, both the first zipper tab 222 and the second zipper tab 223 slide toward the direction A, B, or C. It illustrates in FIG. 8 that both the first zipper tab 222 and the second zipper tab 223 slide toward the direction B and the blocking portion 25 is blocked in the interior space 214, thus the strap 23 can be held in the wrist or be exerted as a shoulder strap. Furthermore, people can simply carry out the articles from the bag 2 by drawing the first zipper tab 222 or the second zipper tab 223.
To sum up, the present invention notably takes advantage of a portable bag comprising a blocking portion engaged to the strap loop of the strap, which has a larger outer diameter than a dimension of the detaching portion while drawing the zipper together, so as to block the blocking portion in the bag through the movement of the zipper. Additionally, the blocking portion can also be pulled out through slightly drawing the zipper apart, thereby increasing the use convenience and the use efficiency without spending much time looking for the personal articles from the bag.
While we have shown and described the present invention with reference to the specific preferred embodiment, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
